Plastic uptake process for PVC film

Abstract

The invention discloses a plastic uptake process for a PVC film. A first shell, a feeding mechanism, a pushing mechanism, a cleaning mechanism, a heating mechanism, a limiting mechanism, a collectingmechanism and an air suction mechanism are included. The plastic uptake process has the beneficial effects that the feeding mechanism is mounted on the first shell, the pushing mechanism is mounted onthe first shell, moving of PVC plastic hard sheets is facilitated through the feeding mechanism and the pushing mechanism, and the PVC plastic hard sheets can be continuously placed below the heatingmechanism easily; the cleaning mechanism is mounted on the first shell, when the PVC plastic hard sheets pass through the cleaning mechanism, the cleaning mechanism cleans the bottom ends of the PVCplastic hard sheets, scraps on the PVC plastic hard sheets are fixed, and therefore collecting and cleaning of scraps are facilitated; and the limiting mechanism is fixed to the first shell, and locating of the PVC plastic hard sheets is facilitated through fixing of the limiting mechanism to the PVC plastic hard sheets.

Description

technical field [0001] The invention relates to a plastic-absorbing process, in particular to a PVC film plastic-absorbing process, and belongs to the field of plastic-absorbing technology. Background technique [0002] Blister molding is a kind of plastic processing technology. The main principle is to heat and soften the flat hard plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. The main advantages of blister packaging are that it saves raw and auxiliary materials, light weight, convenient transportation, good sealing performance, and meets the requirements of environmentally friendly green packaging; it can pack any special-shaped products without additional cushioning materials for packing; the packaged products are transparent and visible, Beautiful appearance, easy to sell, suitable for mechanized and automatic packaging, conveni...

Problems solved by technology

[0003] However, when blistering, since the bottom of the PVC plastic hard sheet is stained with debris, and when the user holds the plastic hard sheet, the dirt on the hands will be contaminated on the PVC plastic hard sheet. The bottom surface, so that when the vacuum pump is used to pump air, debris will enter the vacuum pump, causing damage to the vacuum pump and reducing the service life of the vacuum pump, and these debris will also be contaminated on the abrasive tool, affecting the plastic absorption of PVC plastic hard sheets At the same time, when the PVC plastic hard sheet is prevented from being heated on the blister machine, the PVC plastic hard sheet needs to be placed directly above the mold, but when the PVC plastic hard sheet is placed, the PVC plastic The position of the hard sheet is offset, so that the image of the mold after blistering is not in the center of the PVC plastic sheet, which is not conducive to the stacking and use of the blistered PVC plastic sheet
