A good pressure holding control method helps reduce product shrinkage and improve the appearance quality of the product. For some products, pressure maintenance is typically done manually, which is time-consuming, labor-intensive, and inefficient. Understandably, the aforementioned solution addresses this by having the following steps during the pressure maintenance operation: First, the No. 1 blocking cylinder extends, the carrier flows into the flow line from the previous workstation, the No. 1 positioning cylinder activates, the barcode scanner 20 scans the QR code, the material dispensing cylinder 21 extends, the No. 1 blocking cylinder and the No. 1 positioning cylinder retract, the carrier flows into the next workstation, defective products are blocked by the No. 2 blocking cylinder, and the transport module 11 transports them to the defective product flow line 12. For good products, the No. 2 blocking cylinder does not extend, and the product flows into the next workstation. The No. 4 blocking cylinder extends to block the carrier. The second and third positioning cylinders are raised, and the first and second pressure-holding mechanisms 13 and 14 hold the product under pressure. After pressure holding, the product flows into the next workstation. Compared with the prior art, the automated pressure-holding device, which includes the frame 1 and is set in the frame 1, with an intermediate flow channel between the above mechanisms, can quickly and effectively hold the product under pressure with high efficiency. This effectively solves the problem that different shaped products require different pressure holding pressures. A good pressure holding control method helps to reduce product shrinkage and improve the appearance quality of the product. Currently, pressure holding of products is generally done manually, which is time-consuming, labor-intensive, and inefficient.
