Automatic feeding and discharging device for assisting in plastic uptake

Abstract

The invention discloses an automatic feeding and discharging device for assisting in plastic uptake. The automatic feeding and discharging device comprises a plastic uptake mechanism, a pushing mechanism, a taking and placing mechanism and a discharging mechanism; the pushing mechanism is horizontally arranged; a carrying plate at the top of the pushing mechanism linearly slide to and fro in the straight line direction; the plastic uptake mechanism comprises an upper plastic uptake part and a lower plastic uptake part; the two plastic uptake parts are separately and correspondingly arranged atthe upper part and the lower part of the pushing mechanism up and down; the taking and placing mechanism spans a part above the pushing mechanism; the discharging mechanism is arranged on one side ofthe pushing mechanism; and a plastic sheet to be plastic-uptaken is loaded on the carrying plate of the pushing mechanism. In plastic uptake, a plastic hard plate is automatically sucked in, and a product is automatically ejected or pushed back and automatically sucked and carried after plastic uptake is finished, so that the production efficiency of the plastic uptake is effectively improved, the plastic uptake cost of a single plate is reduced, and the plastic uptake quality is ensured well.

Description

technical field [0001] The invention relates to the field of blister automation, in particular to an automatic loading and unloading device for assisting blistering. 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. [0003] Blister technology is widely used in the market, but the existing plas...

AI Technical Summary

Problems solved by technology

[0003] Blister technology is widely used in the market, but the existing plastic hard sheet is generally divided into pieces manually, and then the plastic hard sheet is manually sent into the blister mechanism. The finished product is taken out; this purely manual method of blister loading and unloading has the following technical defects in the actual production process: 1. The production efficiency of manual loading and unloading of plastic hard sheets is low, and the production capacity cannot be effectively improved, resulting in high blister cost ;2. In order to improve the efficiency of blistering in the process of plastic hard disk blistering, it is often possible to blister multiple pieces of material at the same time, but manual feeding can only pick and place a single piece of material, so it is necessary to equip multiple operators to operate at the same time to complete the normal work , high labor cost; 3. When manually feeding materials into the blister mechanism, the accuracy of each discharge position cannot be guaranteed, and the position deviation of the discharge is prone to occur, and the material may not completely cover the vacuum suction port of the blister mechanism, resulting in a vacuum Blister failure; 4. In addition, after the completion of the blister, the softened plastic is absorbed by the vacuum negative pressure to form a product. After cooling and forming, there may be a situation of adhesion and fixation with the blister table. In this case, the material is taken out manually High difficulty
