Full-automatic plastic sucking and punching former

Abstract

The invention relates to a full-automatic plastic sucking and punching former which comprises an unreeling device, a sheet feeding device, a heating device, a forming device, a finished product withdrawal device, a caterpillar track device and a caterpillar track adjustment device, wherein the unreeling device, the sheet feeding device, the heating device, the forming device and the finished product withdrawal device are arranged on a rack in sequence; and the caterpillar track device and the caterpillar track adjustment device are arranged on the heating device and the forming device and connected with the sheet feeding device. The full-automatic plastic sucking and punching former is characterized by further comprising a cup switching device and a cup flanging device, wherein the cup switching device and the cup flanging device are arranged on the rack between the forming device and the finished product withdrawal device in sequence. By independently driving an upper template, the problem of excessive impact force during die spotting is solved, so that the punching shearing speed is increased; a cutter device which is provided with a ring-shaped cutter and a cutter baffle is arranged, so that the problem of adhering materials on the blade is solved and then the forming and punching shearing of PP (Propene Polymer) materials can be carried out at the same time; and the cup switching device and the cup flanging device are arranged, so that the full-automatic thermal forming production of the PP materials is realized, the production efficiency is improved and the flanged edge has better quality and more beautiful appearance.

Description

technical field [0001] The invention relates to a molding device, in particular to a fully automatic blister punching molding machine. Background technique [0002] PP is a semi-crystalline material, which is harder and has a higher melting point than PE, and is a homopolymer type. Because the homopolymer PP temperature is very brittle above 0C, many commercial PP materials are random copolymers with 1 to 4% ethylene or block copolymers with higher ethylene content. Copolymer PP materials have a lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but have stronger impact strength, and the strength of PP increases with the increase of ethylene content . The Vicat softening temperature of PP is 150°C. Due to the high crystallinity, the surface stiffness and scratch resistance of this material are very good, and PE does not have the problem of environmental stress cracking. Therefore, in the plastic thermoforming industry, PP has gradual...

Problems solved by technology

In this way, it is difficult to realize the automatic production of the thermoforming machine, which reduces the production efficiency. In addition, punching, shearing and hemming after cooling will obviously increase the difficulty of hemming and affect the quality of hemming
