Plastic sheet forming machine

Abstract

The invention relates to the field of plastic forming equipment, and discloses a plastic sheet forming machine. The machine comprises forming equipment. The forming equipment comprises a transmission structure. The transmission structure comprises a first guide column, a transmission shaft and a driving device in transmission connection with the transmission shaft, wherein a first upper mold disc and a first lower mold disc are slidably mounted on the first guide column, and the transmission shaft is in transmission connection with the first upper mold disc and the first lower mold disc. Blanking equipment comprises a waste removing mechanism, and the forming equipment further comprises a mold disc position fine adjustment device. According to the structure, mold opening and mold closing are achieved through one power source, the structure of the machine is more compact, accurate positioning and continuous motion control are achieved through the fine adjustment device, the problem that plastic sheets are difficult to clean is solved through waste collection, neatness and attractiveness of a workbench are guaranteed, and the working efficiency of workers is improved.

Description

technical field [0001] The invention relates to the field of plastic molding equipment, in particular to a plastic sheet molding machine. Background technique [0002] The molding and manufacturing method of plastic products such as beverage cup lids, coffee cup lids, and medicine food trays is to first place a tube of plastic sheets on the loading rack, and the plastic sheets are first softened by a heating device, and then blow molded in a blow molding device. , and finally cut into shape by a punching and cutting device and finally sent out. In the molding process, the upper and lower molds need power sources to drive respectively. Different products need to be replaced with different molds. Then, it is necessary to adjust the closed height of the upper and lower molds. The general structure is through the nut on the first guide post. Manual adjustment is performed, but the stroke is difficult to control during the operation, and the adjustment is not accurate, and gener...

AI Technical Summary

Problems solved by technology

In the molding process, the upper and lower molds need power sources to drive respectively. Different products need to be replaced with different molds. Then, it is necessary to adjust the closed height of the upper and lower molds. The general structure is through the nut on the first guide post. Manual adjustment, but the stroke is difficult to control during the operation, the adjustment is not accurate, and generally there are four first guide pillars, all of which need to be adjusted, it is difficult to control the level of the mold plate, and multiple adjustment operations are required to complete the height adjustment

Although the structure is simple, the equipment cost is high and the production efficiency is very low, resulting in high product cost, low product precision and high scrap rate

However, the operation is cumbersome and complicated, which wastes manpower and time, resulting in low production efficiency, high product cost, low product precision and high scrap rate.

[0003] Some follow-up processes need to punch plastic products. In the actual operation process, there is a big problem with the cleanliness of the punching machine. Because plastic products, especially plastic sheet products, are soft, light, and a little sticky, the workbench There are often a lot of waste on the table, which is often scattered everywhere by external force. It takes a lot of time and energy to clean up the waste on the table.

Moreover, the uncleaned work surface is very unsightly, so a device is needed to solve this problem
