1、紙塑包裝制品生產(chǎn)工藝指導(dǎo)Production process guidance of paper pulp packing products 制漿、供漿系統(tǒng)： Pulping and pulp supply system1 原漿板或廢回收紙： 在制漿車間規(guī)劃出專用的區(qū)域分類擺 放好原漿板或廢回收紙，在進(jìn)入擺放區(qū)的原料應(yīng)先做好雜質(zhì)、 粘膠紙、裝訂針、包裝帶的分揀工作，以防雜質(zhì)混入紙漿后影 響成品的外觀和結(jié)構(gòu)力。Virgin pulp board or recycled waste paper: You need to prepare a special place to put the virg

2、in pulp board or recycle waste paper. Before you put the raw material in the area, please sort out impurities, adhesive paper, binding needing and packing belt from raw material to prevent impurities mixed with paper pulp effecting the appearance and structure.2 碎漿 :原料在進(jìn)行破碎分解之前，先在磅秤上稱好重量，然 后再通過人工投料或

3、原料輸送帶進(jìn)給的方式逐一將原料投到 水力碎漿機(jī)的工作桶里， 加入適量的水混合， 然后起動(dòng)碎漿機(jī)； 碎漿時(shí)間一般情況下為2030分鐘，和原料的含水率、成份 以及水溫有關(guān)。Pulping: Before pulping, you should weight, then put the raw material to barrel of hydrapulper by manual or conveyor, addsome water, then start the machine. Generally, the pulping time is 20-30min according to the mo

4、isture content of raw material and water temperature.3 放漿 :水力碎漿機(jī)制好的漿通過機(jī)器底部的放漿閥直接排 放到濃 /配漿池或由連接在放漿管上的漿料輸送泵到濃漿池， 放漿過程中碎漿機(jī)一邊運(yùn)轉(zhuǎn)一邊打開進(jìn)水閥適量的沖水； 對紙 漿分解度要求較高的場合， 還要在漿料輸送泵的后一級增加紙 纖維疏解除砂磨漿機(jī)。Draw off paper pulp: After pulping, the paper pulp will flow to pool through the release valve in the bottom of the machi

5、ne, or flow to the pipe which connect to the pool. And during this process, should turn on the hydrapulper and open inlet valve to pour into some water. If you have a requirement about pulp decomposition degree, you can add one process of pulp fiber revocable sand pulping machine.4 濃/配漿 :從水力碎漿機(jī)或前一級漿

6、泵（包括磨漿）輸送到 濃漿池中的漿料由安裝在濃 / 配漿池上的漿料攪拌器充分?jǐn)?拌、加水混合均勻 ,這時(shí)濃 /配漿池中的漿料濃度應(yīng)調(diào)為符合生 產(chǎn)要求的供漿濃度約為。這時(shí)可根據(jù)紙漿產(chǎn)品對防水防油防潮的要求加入適量的添加 劑，對有些添加劑有特殊工藝要求的可放入碎漿機(jī)中充分?jǐn)嚢?混合。Thick/mixing pulp: After the pulp flows to the pool, add some water, there is pulp pond beater which installed on the pool to stir the paper pulp, adjust the pa

7、per pulp to the required concentration of can add some additives in the pool according to the requirement of water proof, oil proof and damp proof, and stir the paper pulp to mix it.5 供漿 :前一級配漿泵將配漿池中調(diào)好濃度、攪拌均勻、符合 生產(chǎn)工藝要求的漿通過配漿泵泵到供漿池中， 再由供漿泵輸送 給生產(chǎn)線上的各成型設(shè)備， 成型設(shè)備的溢流漿通過溢流回漿管 路再回到供漿池。Paper pulp supply: Aft

8、er the pulp adjusted, the paper pulp will pumped to the pulp supply pool by pulp pump. Then pulp pump will supply the pulp to the forming machine. The overflow pulp of forming machine will return to the pulp supply pool through pipe. 產(chǎn)品成型系統(tǒng) : Forming system1. 半自動(dòng)餐盒成型機(jī)開機(jī)前應(yīng)檢查各運(yùn)動(dòng)部件的潤滑油情況,機(jī)器內(nèi)儲氣罐的排水閥、氣源三

9、聯(lián)體中油杯的油量 .Please check the lubricating situation of forming machine, check the oil mass of drain valve, gas triplets in compressed air pot before start the machine.2. 開機(jī)前檢查模具的緊固情況 ,模具表面網(wǎng)面有沒有紙漿或損壞 的情況 ,洗模和洗毛邊的供水狀況以及噴嘴有沒有堵塞 .Check the fastening situation of mould, check whether there is pulp or damage

10、 on the wire mesh, check the water supply situation and spray nozzle is plug or not.3. 空氣壓縮系統(tǒng)工作后 ,檢查到半自動(dòng)餐盒成型機(jī)的氣源壓力是否穩(wěn)定在56kg/cm2,然后起動(dòng)半自動(dòng)餐盒成型機(jī)。After air compressed system works, check whether the air source pressure of the forming machine is in 5 6kg/cm2 or not, then start the machine.4. 起動(dòng)供漿系統(tǒng)后 ,觀察進(jìn)入

11、機(jī)器漿桶里的漿料濃度情況,同時(shí)打開漿桶底部的攪拌吹氣手動(dòng)閥 ,溢流情況是否正常 .Start pulp supply system and observe the concentration situation of pulp in the barrel. Meanwhile, open blow valve of bottom tank to check whether the overflow is normal.5. 上述環(huán)節(jié)確認(rèn)正常后 ,既可轉(zhuǎn)入生產(chǎn) .After the above steps are normal, then you can start the production

12、.6. 每天下班后要將模具沖洗干凈 ,以防吸附在模具網(wǎng)上的紙纖維 時(shí)間長積累多了后造成堵網(wǎng)現(xiàn)象 ;機(jī)器漿桶內(nèi)的余漿在用不完 的情況下盡量排掉 ,然后沖洗干凈 ,以免因氣溫高的時(shí)候在漿桶 內(nèi)發(fā)酵腐爛 .Clean the mould before you stop the machine, to avoid the paper pulp stick on the wire mesh and it will cause plug net from day to day. Please draw off the rest of paper pulp and clean the barrel, to

13、prevent the pulp fermentation decay in the tank.三、循環(huán)水系統(tǒng) : Circulating water system:1. 半自動(dòng)餐盒成型機(jī)成型模具上真空脫水出來的白水通過真空 管道流入負(fù)壓 /排水罐中 ,由安裝在排水罐上的液位傳感器控制 排水電磁閥而開關(guān)系統(tǒng)中相應(yīng)的氣動(dòng)閥和單向止回閥的工作， 從而將系統(tǒng)中的循環(huán)白水排放到回水池中存儲， 以供制漿系統(tǒng) 碎漿、調(diào)漿用 .When the forming machine produces products, extract the vacuum from forming mould, the wate

14、r of paper pulp will be squeezed and the water will flow to vacuum subnormal pressure container / water discharge container. Start liquid level sensor control drainage solenoid valve of water discharge container, pneumatic valve of switch system and check valve, to make the water discharge into wate

15、r recycle pool for pulping, pulp adjusting.2. 制漿系統(tǒng)中各環(huán)節(jié)上的調(diào)漿稀釋用水由循環(huán)回水池上的水泵 供給 ,這樣就保證了循環(huán)水的重復(fù)利用 .The water which used for pulping is from the water recycle pool by pump, it ensures the circulating water reuse.3. 循環(huán)水的更換時(shí)間因氣溫、原料和生產(chǎn)情況等因素而不確定 , 一般1530個(gè)生產(chǎn)日，更換循環(huán)水時(shí)應(yīng)完全抽干凈循環(huán)回水池 中的水 ,將池內(nèi)沉淀物全部沖洗干凈 .The time of Cha

16、nging the circulating water is according to the temperature, raw material and production, generally, you need to change the water in 15-30days, extract the water and clean the water cycle pool.四、真空泵供水系統(tǒng) : Vacuum water supply system1. 方法一 ：水環(huán)式真空泵工作過程中要不斷的用水， 對一般生產(chǎn) 量不太大， 每天只有一班進(jìn)行生產(chǎn)的， 可以考慮用一臺真空泵 專用供水泵抽

17、循環(huán)回水池中的循環(huán)水供真空泵使用。Method 1: You should constantly use water during the water ring vacuum pump working, if the production is small, just use one shift of workers, you can consider using one set of pump which special for vacuum to pump the circulating water for circulating water supply pump using.2. 方法

18、二： 水環(huán)式真空泵工作過程中要不斷的用水 ,對于水的純 凈度有一定要求 ,供水壓力在 200hpa 就能滿足要求 ,所以整個(gè) 真空泵用水采用清水罐獨(dú)立供水 .視真空泵功率大小和循環(huán)水 溫、水量看是否需要配置冷卻塔散熱系統(tǒng)。 具體接駁時(shí)在真空 清水罐的出口處設(shè)有手動(dòng)閥 ,每天上班前打開閥門 ,下班后關(guān)閉 , 以防長時(shí)間有水浸著銹蝕真空泵 .氣溫在零度以下的地方還要 注意做好防凍措施 .Method 2: You need to add water constantly during machine working period, and water purity should be requir

19、ed. The water supply press should be 200hpa to satisfy the requirement. So it adopts clean water tank to supply water separately in whole vacuum pump, and to check whether needs cooling tower cooling system according the power of vacuum pump and circulating water temperature and water level. After c

20、onnection, there is a manual valve in the exit of vacuum clean water tank, open the valve before work and close after work to prevent water rusts vacuum pump, and you need to make anti-freezing measures when the temperature is below zero degree.五、空氣壓縮系統(tǒng) :Compressed air system1. 螺桿式空氣壓縮機(jī)、 儲氣罐和壓縮空氣組成的

21、空氣壓縮系統(tǒng)是 為整個(gè)成型系統(tǒng)提供干凈穩(wěn)定的氣源 ,日常維保做的好基本上 是無故障的 .Air compressed system is composed of screw air compressor, compressed air pot and compressed air, which provide clean and stable air source for all forming system. And there is no malfunction if you make daily maintenance.2. 每天下班后放盡儲氣罐里的壓縮空氣 ,打開儲氣罐底部的放水 閥排

22、完儲氣罐中的冷凝水 .Releaseall the compressed air of compressed air pot and open water drain valve of pot bottom to release all condensate water.3. 在室溫較高或空氣相對濕度較大的季節(jié) ,一定要開壓縮空氣冷干機(jī)冷凝壓縮空氣中的水份 ,防止高溫高壓含有一定水份的壓 縮空氣進(jìn)入到設(shè)備中損壞氣動(dòng)元件 ,在低溫干燥的冬季視具體 情況可不開冷干機(jī) ,關(guān)閉冷干機(jī)進(jìn)出口閥門 ,打開冷干機(jī)直接閥 門即可.If the room temperature is high or air r

23、elative humidity is high, you should open compressed air dryer to compress the moisture of air to prevent the compressed air enter into machine to destroy the pneumatic elements in the high temperature and high pressure. In low temperature of winter, you can stop the compressed air dryer according to the situation, close inlet and outlet valves and open direct valve of compressed air d
