Full automatic packing scale is a kind of packaging machinery, in the packaging industry occupies the position of play a decisive role and value in use, it provides the necessary technical equipment in the packaging process, the finished products. Although the packaging machinery production in the whole packaging industry in the proportion of less packaging materials, does not belong to a regular consumables, but integral to the packaging industry modernization is support. Without modern packaging machinery, no packaging industry modernization. Packaging machinery as a professional machinery, in addition to more than the general requirements general machinery, but also has beautiful appearance, compact structure, smooth operation, transmission device of high precision, high production efficiency, to perform well in its function, to meet the market demand.
Full automatic packing scale is a great potential for development of packaging machinery. With the continuous progress of science and technology, many new technologies have been applied in the automatic packaging machine. As people's consumption concept is changing, the packing of the goods to the crucial impact on people's purchasing behavior, many enterprises have to pay attention to the full automatic packing scale.
Quantitative scale of production enterprises of our country on a small scale, product design, research and development of component is very weak. Quantitative packaging industry in China in the past in a long-term low level of productivity, the main technology is not high situation, most enterprises are still in each other's internal and external technology copy copy, the original management stage to reduce production cost. Some artisanal small enterprises with a set of drawings of survival, blindly pursue low-cost, seriously disrupting the domestic market. Enterprises do not have independent intellectual property rights, especially the control of the core technology, the controller is quantitative packaging machinery of the brain, most enterprises are required to buy from foreign or joint ventures, wholly foreign owned enterprises. At present, the quantitative packaging equipment in China has entered a new period of adjustment of product structure, improve the ability to develop. Technology upgrading, product upgrading is an important topic in the development of the industry. Low level development will influence the quantitative packaging machinery to the whole
The rapid development of a quantitative packaging industry, so must strive to change the backward situation. To strive for greater domestic and international market.
Quantitative packing scale by weighing unit, trolley, sewing and conveying device, a pneumatic system, dust removal system, composed of quantitative packaging control instrument etc.. The key component influencing the speed and accuracy of the package is weighing unit, which comprises a storage silo, gate, a cut-off device, the scale body, a bag clamping device, stent, electrical control device. A storage bin for buffer hopper, for material reserve and provide a nearly uniform material flow; the gate is located at the bottom of the storage silo, when equipment maintenance or failure occurs, for the material blocking in the storage bin; a cut-off device consists of a cutting hopper, cut-off gate, pneumatic components, air door, to provide fast, slow two feeding levels in weighing process, the fast, slow feeding material flow can be adjusted separately, so as to ensure quantitative packing scale to meet the accuracy requirement of measurement and speed requirements; air door for balance weighing system air pressure; the scale body is mainly composed of a weighing hopper, bearing bracket and the weighing sensor, complete the weight to the signal transformation and transmission to the control unit; a bag clamping device is mainly composed of a bag clamping mechanism, pneumatic components such as the composition, role for the packaging bag tightly, let all the material weighing completed into package bags; electric control device comprises a weighing display controller, electrical components, control cabinet composition, function control system for work, make the whole system according to the preset program, orderly work.
Quantitative packing scale by weighing method can generally be divided into a bucket (net) scale and no bucket (GW) scale.
A hopper scale work will need to weigh the material through the feeding device is added to a weighing sensor for measuring weight balance. A hopper scale bearing device is a hopper, discharging device installed valve in the hopper bottom is a quantitative packing scale system. However, because the packaging materials (bag) inconsistent weight, no bucket weighing system work each weighing cycle must determine the tare weighing unit changes. Therefore, in each weighing cycle must be by the computer weighing control instrument automatic "peeled", because "peeled" occupied for several seconds, the packing speed without hopper scale of influence. Hopper can be used in the square hopper is arranged at the bottom of one or two to open the valve structure, the use of cylinder to drive the valve discharge. A bucket weighing precision, fast speed, and can be composed of two scale (and above) system, greatly improve the packing speed.
No hopper scale structure saves the hopper component, the weighing sensor is installed directly in the hopper and a bag clamping device, work material directly into the folder in the folder bag institutions on pocket weighing. Because there is no hopper scale omits the hopper component, greatly reduce the scale body height, suitable for packaging of the low.
With the development of science and technology, all kinds of food, aquatic products, put forward new demands on food packaging technology and equipment. At present, food packaging machinery increasingly fierce competition, the future food packaging machinery will coincide with the industrial automation, promote improve the overall level of packaging equipment, food packaging equipment the development of multi-function, high efficiency, low consumption.
Most enterprise annual output value of several million yuan to 10000000 yuan, 1000000 yuan less than a few enterprises still. Nearly 15% of the enterprises production or closed down every year, but 15% of the enterprises to join the industry, extremely unstable, hindered the stability of the development of the industry.
To adapt to the international market demand, development of green packaging machinery.
After joining the WTO, the international packaging machinery industry competition is becoming increasingly fierce, foreign green trade barriers put forward higher requirements on food packaging machinery industry, therefore, must change the traditional packaging machinery design and development model,
Taken into consideration at the design stage to make the packaging machinery in its whole life cycle (design, manufacture, assembly, use, repair and waste disposal processes) no effect or impact on the environment, resource consumption minimization, easy recovery and "green", to enhance the core competitiveness of China's packaging machinery.
Full automatic packing balance premise of continuous development in the packaging industry, under changing. New product development from research imitation tracking situation, has strong competitiveness, stimulate economic growth, improve the efficiency of. But there are some packaging machinery enterprises has not yet been achieved extensive management, fine management, between some packaging machinery enterprises in people's cognition and use and the law of market economy does not adapt phenomenon. Full automatic packing scale has:

全自動包裝秤是包裝機械中的一種,在包裝工業(yè)中占著舉足輕重的地位和利用價值,它給行業(yè)提供了必要的技術(shù)設(shè)備,以完成產(chǎn)品的包裝工藝過程。盡管包裝機械的產(chǎn)值在整個包裝工業(yè)中所占的比重不如包裝材料大,不屬于經(jīng)常性消耗品,但對包裝工業(yè)的現(xiàn)代化卻是不可或缺的支撐。沒有現(xiàn)代化的包裝機械,就沒有現(xiàn)代化的包裝工業(yè)。包裝機械作為專業(yè)性機械,除了比普通機械的一般要求外,還要有外表美觀、傳動裝置緊湊、運轉(zhuǎn)平穩(wěn)、精度高、生產(chǎn)效率高等要求,以很好地完成自身功能,適應(yīng)市場需求。
全自動包裝秤是極具發(fā)展?jié)摿Φ囊豢畎b機械。隨著科學(xué)技術(shù)的不斷進步,很多新技術(shù)被應(yīng)用在自動包裝機上。隨著人們的消費觀念不斷的發(fā)生著變化,商品的包裝對人們的購買行為起到至關(guān)重要的影響,很多企業(yè)紛紛把關(guān)注的目光投向了全自動包裝秤。
我國定量秤生產(chǎn)企業(yè)以小規(guī)模為主,產(chǎn)品的設(shè)計、研究和開發(fā)環(huán)節(jié)非常薄弱。我國的定量包裝工業(yè)過去長期處于一種生產(chǎn)力水平低下、主體技術(shù)不高的狀況,大部分企業(yè)目前仍然處于互相照搬照抄國內(nèi)外技術(shù),降低生產(chǎn)成本的原始經(jīng)營階段。更有一些作坊式的小企業(yè)用一套圖紙存活,一味的追求低成本,嚴(yán)重擾亂國內(nèi)市場。企業(yè)沒有自主知識產(chǎn)權(quán),尤其是核心的控制技術(shù),控制器是定量包裝機械的大腦,大多數(shù)企業(yè)卻需要從國外或合資、獨資企業(yè)購買。目前,我國的定量包裝設(shè)備已進入調(diào)整產(chǎn)品結(jié)構(gòu)、提高開發(fā)能力的新時期。技術(shù)升級,產(chǎn)品換代是行業(yè)發(fā)展的重要課題。定量包裝機械的低水平發(fā)展必將影響到整個定量包裝工業(yè)的快速發(fā)展,所以必須努力改變其落后狀況。爭取更大的國內(nèi)和國際市場。
定量包裝秤由稱重單元、小車、縫包輸送裝置、氣動系統(tǒng)、除塵系統(tǒng),定量包裝控制儀表等組成。其中影響打包速度和準(zhǔn)確度的關(guān)鍵部件是稱重單元,它包括儲料倉、閘門、截料裝置、秤體、夾袋裝置、支架、電氣控制裝置等。儲料倉為緩沖式料倉,用于物料儲備并提供一個接近均勻的物料流;閘門位于儲料倉底部,當(dāng)設(shè)備檢修或出現(xiàn)故障時,用于將物料封阻在儲料倉內(nèi);截料裝置由截料斗、截料門、氣動元件、補氣門等組成,在稱重過程中提供快、慢兩級給料,其快、慢給料的物料流均可單獨進行調(diào)整,從而保證定量包裝秤滿足計量的準(zhǔn)確度要求和速度要求;補氣門的作用為平衡稱重時系統(tǒng)內(nèi)的空氣壓差;秤體主要由稱量斗、承重支架和稱重傳感器組成,完成重量到電信號的轉(zhuǎn)變并傳輸給控制單元;夾袋裝置主要由夾袋機構(gòu)、氣動元件等組成,作用為夾緊包裝袋,讓稱重完畢的物料全部落入包裝袋;電氣控制裝置由稱重顯示控制器、電氣元器件、控制柜組成,作用為控制系統(tǒng)工作,使整個系統(tǒng)按預(yù)先設(shè)定的程序,有序工作。
定量包裝秤按稱重方式一般可以分為有斗(凈重)秤和無斗(毛重)秤。
有斗秤工作時將需要稱重的物料通過給料裝置添加到裝有稱重傳感器的秤斗中進行測重。有斗秤的承載裝置就是秤斗,安裝在秤斗底部的活門就是定量包裝秤系統(tǒng)的卸料裝置。但是,由于包裝材料(袋)重量的不一致性,無斗秤系統(tǒng)工作時每個稱重周期必須測定稱重單元的皮重變化。因此,在每個稱重周期前必須由電腦稱重控制儀表自動“去皮”,由于“去皮”占用了數(shù)秒鐘的時間,使得無斗秤的包裝速度受到一定的影響。秤斗可以采用在方形秤斗的底部設(shè)置一個或兩對開活門的結(jié)構(gòu),使用氣缸驅(qū)動活門卸料。有斗秤稱重精度高,包裝速度快,且可以組成雙秤(及以上)系統(tǒng),大大提高包裝速度。
無斗秤結(jié)構(gòu)省去了秤斗部件,將稱重傳感器直接安裝在下料斗和夾袋裝置上,工作時將物料直接放到夾在夾袋機構(gòu)上的口袋里進行稱重。由于無斗秤省去了秤斗部件,大大降低了秤體的高度,適合包裝現(xiàn)場低矮的場合。
隨著科學(xué)技術(shù)的不斷發(fā)展,各種食品、水產(chǎn)加工品的出現(xiàn),對食品包裝技術(shù)和設(shè)備都提出了新的要求。目前,食品包裝機械競爭日趨激烈,未來的食品包裝機械將配合產(chǎn)業(yè)自動化,促進包裝設(shè)備總體水平提高,發(fā)展多功能、高效率、低消耗的食品包裝設(shè)備。
多數(shù)企業(yè)年產(chǎn)值在幾百萬元到1000萬元之間,低于100萬元的企業(yè)為數(shù)還不少。每年有近15%的企業(yè)轉(zhuǎn)產(chǎn)或倒閉,但又有15%的企業(yè)加入這個行業(yè),極其不穩(wěn)定,現(xiàn)象阻礙了行業(yè)發(fā)展的穩(wěn)定性。
適應(yīng)國際市場要求,開發(fā)設(shè)計綠色包裝機械。
加入WTO后,國際包裝機械行業(yè)競爭日益激烈,國外的綠色貿(mào)易壁壘對食品包裝機械行業(yè)提出更高的要求,所以,必須改變傳統(tǒng)的包裝機械設(shè)計及開發(fā)模式,
在設(shè)計階段考慮到使包裝機械在其全生命周期中(設(shè)計、加工制造、裝配、使用、維修直至廢棄后處理處置過程)對環(huán)境無影響或影響最小化、資源低耗、易于回收等"綠色特征",以提升我國包裝機械的核心競爭力。
全自動包裝秤在包裝行業(yè)不斷發(fā)展的前提下不斷改變、精進。新產(chǎn)品開發(fā)擺脫仿研跟蹤的局面,競爭力曾強,拉動經(jīng)濟增長、效益提升。但是還存在一些包裝機械企業(yè)管理粗放,精細(xì)化管理尚未實現(xiàn),一些包裝機械企業(yè)對人的認(rèn)識和使用與市場經(jīng)濟規(guī)律之間不相適應(yīng)等現(xiàn)象。全自動包裝秤具有:
1、簡潔化,自動化。新型包裝機械普遍具備多功能、調(diào)整操作簡單等條件,機電一體化是包裝控制器的新趨勢。全自動包裝秤將配合產(chǎn)業(yè)自動化趨勢,新型設(shè)備及技術(shù)得到了普及。制造企業(yè)將趨向購買操作簡易且安裝容易的包裝機械,尤其是當(dāng)前制造業(yè)大量裁員,對簡易操作系統(tǒng)的需求將與日俱增。結(jié)構(gòu)運動控制等事關(guān)包裝機械性能的優(yōu)劣。
2、高效生產(chǎn)率。包裝機械廠商越來越注重開發(fā)快速、成本較低的包裝設(shè)備,未來的發(fā)展趨勢是設(shè)備更小型、更靈活機動、多用途、高效率。此趨勢還包括節(jié)約時間、降低成本,因此包裝界所追求的是組合化、簡潔化、可移動的包裝設(shè)備。在包裝機械自動化方面,自動化操作程序已獲得廣泛應(yīng)用。
3、配套完善。只重視主機生產(chǎn),而不考慮配套設(shè)備完整,將使包裝機械應(yīng)有的功能不能發(fā)揮出來。因此開發(fā)配套設(shè)備,使主機的功能得到最大的擴張,是提高設(shè)備的市場競爭力和經(jīng)濟性至關(guān)重要的因素。機械制造企業(yè)在為用戶提供生產(chǎn)自動線或生產(chǎn)流水線設(shè)備時注重成套完整性,無論是高技術(shù)附加值還是較簡單的設(shè)備,都按配套性要求提供。
包裝行業(yè)最緊迫的是改變包裝機械行業(yè)中各企業(yè)的發(fā)展方式,企業(yè)要站在新的起點上去審視和解決好以上的矛盾和問題,轉(zhuǎn)變發(fā)展理念,強化自主創(chuàng)新,增強市場意識,大力推進國內(nèi)包裝機械行業(yè)發(fā)展。要改變包裝機械行業(yè)現(xiàn)狀,促進包裝機械的發(fā)展,行業(yè)在大步前進的同時要注意包裝機械的發(fā)展趨勢。
全自動包裝秤必須發(fā)展出更為具有特色的新亮點,創(chuàng)新才能占據(jù)更多的市場,要了解整個行業(yè)的最新動態(tài),培養(yǎng)出超前的眼光以及敏感的市場洞察力,這些都是讓全自動包裝秤走在市場的最前沿必不可少的能力。
全自動包裝秤的出現(xiàn)給許多企業(yè)帶來了福音。自動化水平在制造工業(yè)中不斷提高,應(yīng)用范圍正在拓展。包裝機械行業(yè)中自動化操作正在改變著包裝過程的動作方式和包裝容器及材料的加工方法。實現(xiàn)自動控制的包裝系統(tǒng)能夠極大地提高生產(chǎn)效率和產(chǎn)品質(zhì)量,顯著消除包裝工序及印刷貼標(biāo)等造成的誤差,有效減輕職工的勞動強度并降低能源和資源的消耗。具有革命意義的自動化改變著包裝機械行業(yè)的制造方法及其產(chǎn)品的傳輸方式。設(shè)計、安裝的自動控制包裝系統(tǒng),無論從提高包裝機械行業(yè)的產(chǎn)品質(zhì)量和生產(chǎn)效率方面,還是從消除加工誤差和減輕勞動強度方面,都表現(xiàn)出十分明顯的作用。尤其是對食品、飲料、藥品、電子等行業(yè)而言,都是至關(guān)重要的。自動裝置和系統(tǒng)工程方面的技術(shù)正在進一步深化,并得到更廣泛的應(yīng)用。
全自動包裝秤不斷的發(fā)展壯大,包裝設(shè)備行業(yè)得以長久發(fā)展。自動化、新型的包裝設(shè)備一直都是客戶的最終需求,也是自動定量包裝秤的發(fā)展方向,包裝設(shè)備生產(chǎn)廠家對包裝設(shè)備需要進一步的創(chuàng)新與發(fā)展,這樣才能走的更遠(yuǎn)。
