Automatic bag sucking and opening device used in plastic bag packaging process

Abstract

The invention relates to an automatic bag sucking and opening device used in the plastic bag packaging process. The automatic bag sucking and opening device comprises a bag storing mechanism, a bag sucking mechanism, a rack and a sliding rail transmission mechanism. The bag storing mechanism is arranged on the rack and comprises a bag box used for storing package bags. The bag sucking mechanism comprises an upper vacuum suction cup, a lower vacuum suction cup and a lifting mechanism, wherein the upper vacuum suction cup is connected to the lifting mechanism and used for adsorbing and lifting the package bags in the bag box, and the lifting mechanism is connected to the sliding rail transmission mechanism. The sliding rail transmission mechanism is arranged on the rack and used for horizontally moving the adsorbed package bags to the corresponding position of the lower vacuum suction cup. The lower vacuum suction cup is arranged on the rack and used for being matched with the upper vacuum suction cup to open bag openings of the package bags. The automatic bag sucking and opening device is compact in structure and meanwhile needs to meet the requirements for economical efficiency, high efficiency and accuracy, and the production efficiency can be improved. Rapid, repeated and continuous opening of the bag openings of the package bags and bag replacing can be achieved, and labor is saved.

Description

technical field [0001] The invention relates to an automatic bag suction and bag opening device in the plastic bag packaging process. Background technique [0002] In many packaging processes, packaging is generally decomposed into multiple manual processes. Repeatedly opening the mouth of the packaging bag is a very important process. In the traditional packaging industry, manual bag opening is generally used, and the actions are repeated and cumbersome. . The bag opening mechanism is widely used in various packaging processes and automated production processes. The bag opening process is an important process in the packaging process. The use of a fully automatic bag opening mechanism can greatly improve production efficiency and avoid a lot of repetitive and tedious manual work. The bag opening process. The current bag opening mechanism mostly uses guide rollers, cylinders, etc. as power components, and different mechanisms are designed according to specific working purp...

AI Technical Summary

Problems solved by technology

The bag opening mechanism designed with the guide roller structure in the above invention is suitable for opening bags of film-like packaging bags, but not for thicker plastic and packaging bags made of other materials; the bag opening mechanism combined with a rubbing mechanism and an air cylinder This method is suitable for opening heavier woven bags, but the design structure is more complicated for the opening of lighter plastic bags
