Integrated full-automatic thermoforming machine

Abstract

The invention discloses an integrated full-automatic thermoforming machine. The integrated full-automatic thermoforming machine comprises a rack, an output structure, a heating structure, a forming punch structure, a main shaft transmission structure, a programmable logic controller (PLC) control system, a sheet feed stopping structure, a rolling structure, a punching structure and a main speed-down motor. The integrated full-automatic thermoforming machine has the advantages that the structure is simple, a sheet passes through a front and rear conveying structure and the rolling structure which synchronously operate, then the sheet passes through a pre-heating plate which controls the temperature, the stopping structure and the forming punch structure, the whole heating forming is completed once, the error of the shrinkage variable in the processing process of the sheet is effectively reduced, the processing speed and efficiency are improved, the processing accuracy is effectively increased, and the applicability is good.

Description

technical field [0001] The invention belongs to PVC, PET, BOPS, GPPS, HIPS plastic molding equipment, and specifically relates to an integrated full-automatic thermoforming machine. Background technique [0002] Thermoforming machines are common equipment for making and processing various plastic products, such as cups, lids, plates and other containers made of PS, PET, PVC, GPPS, and HIPS materials, which are usually thermoformed by thermoforming machines. [0003] The existing flat-plate heating automatic forming machine is a kind of plastic sheet forming and processing equipment, which uses different molds to heat, air pressure, form, punch, and punch the plastic sheet to complete the processing and production of plastic materials. However, for the thermoforming machine in the prior art, for the workpiece with complex shape, generally one set of molds cannot complete it, and multiple sets of molds are required to form, punch, and punch in sequence. When the various proces...

[0003] The existing flat-plate heating automatic forming machine is a kind of plastic sheet forming and processing equipment, which uses different molds to heat, air pressure, form, punch, and punch the plastic sheet to complete the processing and production of plastic materials. However, for the thermoforming machine in the prior art, for the workpiece with complex shape, generally one set of molds cannot complete it, and multiple sets of molds are required to form, punch, and punch in sequence. When the various processes are connected, due to the heating of the plastic sheet After forming, it is easy to be affected by the environment such as air temperature, and it will cool down, causing the product to shrink, and mold positioning errors will occur during forming, punching, and punching. The whole process is complicated to use, and the processing accuracy is low, which seriously affects production. efficiency
