Automatic bag making machine for blood bags

Abstract

The invention discloses an automatic bag making machine for blood bags, belongs to the technical field of blood bag production equipment, and aims to provide an automatic bag making machine which is high in blood bag processing efficiency and good in forming. The automatic bag making machine for blood bags comprises a feeding device used for feeding and treating two membrane materials, a pretreatment device used for carrying out tearing part fusion welding and pre-cutting on the heads of the two membrane materials, a fusion welding device used for welding the membrane materials and a pipe, a pipe feed device used for conveying a round pipe, a breaking valve and a backflow valve to the position between the two membrane materials, a bag cutting device used for cutting and forming a bag body and cutting a cutting opening corresponding to the tearing part, a discharging device used for grabbing and discharging the bag body and removing waste materials and a membrane drawing device used for moving the two membrane materials to corresponding stations in the bag making process, the tearing part corresponds to the backflow valve, and the breaking valve and the round pipe correspond to the pre-cutting position.

Description

technical field [0001] The invention relates to a blood bag production equipment, more specifically, it relates to an automatic blood bag making machine. Background technique [0002] In the existing technology, in the production process of blood bags, the blood bag bag making machine processes two rolls of PVC film through defilming, half-cutting, film pulling, spot welding, punching, tube loading, bag opening, high-frequency welding, bag cutting, The finished blood bag is made by tearing, output and other processes; the blood bag is equipped with a return valve, which is composed of a valve body and a valve sleeve. When processing the blood bag, the return valve needs to be assembled first, so There is an extra step of reflux valve assembly before bag processing, which increases the complexity of blood bag processing; [0003] In the process of blood bag processing, the existing blood bag making machine is not stable and perfect in the processing of membrane material pull...

AI Technical Summary

Problems solved by technology

[0002]In the production process of blood bags in the prior art, the blood bag bag making machine processes two rolls of PVC film through defilming, half-cutting, film pulling, spot welding, punching Hole, tube, bag opening, high-frequency welding, bag cutting, edge tearing, output and other processes to make the finished blood bag; the blood bag is equipped with a return valve, which is composed of a valve body and a valve sleeve. Generally, it is necessary to assemble and process the return valve first, so there is an extra step of assembling the return valve before blood bag processing, which increases the complexity of blood bag processing;

[0003] In the process of blood bag processing and production, the existing blood bag making machine is not enough for the processing of film pulling, tension adjustment, welding and cutting. Stable and perfect, thus affecting the precision and shaping of blood bag processing
