The mould forming system of disposable tableware in our factory is a kind of automatic continuous multi position hydraulic forming machine. The motion system of the hydraulic system can be connected with PLC control system through RS-232C interface, which lays a hardware foundation for the research and development of PLC control system. The control system shall meet the requirements of reliable forming process, simple operation and convenient maintenance. The control system of injection molding machine in each cycle is divided into 8 processes:
1. In station 2, the expansion motor rotates (3DT function), the forming cylinder rises (1dt function) to the limit position, the hydraulic system pressure rises, and the safety valve unloads for 2.5s. When the upper and lower dies are separated by the rising of the cylinder, the rotating force of the diffusion motor makes it easy to separate the tableware and the dies. The rising of the forming barrel also makes preparation for the projection of the feeding barrel in step 2.
2. When the feed cylinder of station 1 is extended to complete feeding, the stripper cylinder of station 3 is extended (4'dt action), and the tableware is pushed out from the loading bar for 2.5 seconds.
3. Stop 5S and take out the tableware at the third station.
4. While retracting and releasing the loading cylinder of station 1, the release cylinder of station 3 retracts and releases (4dt action) for 1.5s.
5. The rotation (2DT action) of the rotary motor of the disposable tableware mold system is converted to 3s of the workstation.
6. When the double stall motor rotates (3DT function), the forming cylinder drops (1dt function), and the tableware forms for 2.5s.
7. The position of the two forming cylinders is the same, and the compaction and heating curing time is 12s.
8. Stop for 1s.
流程要求:系统控制每个设备依次按照以上8工作步骤循环动作,形成两个电磁铁控制油缸应联锁(也就是说,1 DT和DT只能有一个行动或不行动的同时,不同时),4 DT和4“DT要求是相同的。
Process requirements: each equipment is controlled by the system in turn according to the above 8 working steps, forming two electromagnet control oil cylinders to be interlocked (that is, 1 DT and DT can only have one action or not at the same time, not at the same time), 4 DT and 4 "DT requirements are the same.
In order to meet the requirements of convenient operation, maintenance and adjustment of disposable tableware mould, the following functions need to be realized:
(1) Realize continuous automatic operation and reduce labor intensity of workers
(2) Each process can realize single step, continuous action and inching, which is convenient for maintenance and adjustment.
(3) It can realize emergency stop and reduce accidents.
(4) Realize the indication of working step status (the first step), so as to understand the operation status of the equipment.
