1、 Process flow:

据悉，生产能够降解的一次性餐具的工艺过程主要包括∶选择主料、主料预处理、配料搅拌、定量送料、热压成形、表面喷涂、烘干、包装入库等8个部份。该一次性餐具设备便是基于该生产工艺而设计的，其主要完成定量送料和热压成形过程。即：上料→摊料→加压、加热、保压、卸压→脱模→（移走）→下一个循环。

It is reported that the production process of degradable disposable tableware mainly includes eight parts: selection of main materials, pretreatment of main materials, batching and mixing, quantitative feeding, hot pressing, surface spraying, drying and disinfection, packaging and warehousing. The disposable tableware equipment is designed based on the production process, which mainly completes the quantitative feeding and hot pressing forming process. That is: loading → spreading → pressurizing, heating, pressure maintaining, pressure relieving → demoulding → removing → next cycle.

采用3个工位：一工位完成上料工步，二工位完成加压、加热、保压、卸压工步，第三工位完成脱模与餐具移走的工步。移走工步运用负压吸住餐具然后放到传送带上，这个动作靠气动辅助装置实现。为增加时间利用率和单机生产率，周全利用电动机的功率，减少能耗，部分工作时间并行工作。

There are three working positions: one is to complete the feeding step, the second is to complete the pressurization, heating, pressure holding and pressure relief step, and the third is to complete the demoulding and tableware removal step. The removal step uses the negative pressure to suck the tableware and then put it on the conveyor belt. This action is realized by the pneumatic auxiliary device. In order to increase the time utilization rate and single machine productivity, the power of the motor is fully utilized, and the energy consumption is reduced.

二、一次性餐具设备工艺过程循环的八个工步内容：

2、 There are eight steps in the process cycle of disposable tableware equipment

工步一：在工位二，摊料马达旋转（3DT动作），同时成型缸上升（1'DT动作）到限定位置，液压系统压力升高，溢流阀卸载，时间2.5s。成型缸上升使得模具上下模分开的瞬时间，摊料马达中的旋转力使得餐具和模具易于分离，成型缸上升也为步骤二上料缸伸出做好了准备。

Step 1: in station 2, the spreading motor rotates (3DT action), at the same time, the forming cylinder rises (1'dt action) to the limited position, the hydraulic system pressure rises, and the relief valve unloads, the time is 2.5s. The rising of the forming cylinder makes the upper and lower dies separate. The rotating force in the spreading motor makes it easy to separate the tableware and the die. The rising of the forming cylinder is also ready for the extending of the feeding cylinder in step 2.
                                  

工步二：在工位一上料缸伸出完成上料，在第三工位的脱模缸同时伸出（4DT动作）顶料杆顶出餐具，时间2.5s。

Step 2: the feeding cylinder in station 1 is extended to complete feeding, and the demoulding cylinder in station 3 is extended at the same time (4dt action) to eject the tableware, with a time of 2.5s.

工步三：暂停5s，在第三工位取出餐具。

Step 3: pause for 5S and take out the tableware in the third position.

工步四：在工位一上料缸缩回取料，在第三工位脱模缸同时缩回（4'DT动作）复位，时间1.5s。

Step 4: retract and reclaim the material in the feeding cylinder of station 1, retract and reset the demoulding cylinder of station 3 at the same time (4'dt action), with a time of 1.5s.

工步五：回转马达旋转（2DT动作）转换工位，时间3s。

Step 5: rotary motor rotation (2DT action) conversion station, time 3S.

工步六：在工位二摊料马达旋转（3DT动作）摊料，同时成型缸下降（1DT动作）餐具成形，时间2，55o

Step 6: in the second position, the spreading motor rotates (3DT action) to spread the material, and the forming cylinder descends (1dt action) to form the tableware. The time is 2, 55o

工步七：在工位二成型缸位置保持不变，继续压实并加热固化，时间13.5s。

Step 7: keep the position of the forming cylinder in station 2 unchanged, continue to compact and heat to solidify for 13.5s.

工步八：一次性餐具设备整体停止2s。

Step 8: stop the whole disposable tableware equipment for 2S.
