Heat seal transmission structure of bag machine

Abstract

The invention discloses a heat seal transmission structure of a bag machine. The heat seal transmission structure comprises a fixing base, a transmission wheel, a transmission arm and a heat seal plate. The transmission wheel is arranged in the middle portion of the fixing base, the transmission wheel is connected with one side of a connection arm, the other end of the connection arm is connected with the heat seal plate, and the heat seal plate can be connected with a component on the fixing base. The transmission wheel comprises a sliding track and a sliding connection piece. The sliding connection piece is arranged on the sliding track and connected with the connection arm. A connection shaft is connected with a first connection body and a second connection arm body, and the second connection arm body is provided with an elastic movable rod. According to the heat seal transmission structure, the heat seal plate is conveyed through the round transmission wheel, the speed of the transmission wheel can be freely adjusted, the space between bag openings is guaranteed, the heat seal effect is higher than that of a traditional heat seal transmission piece, meanwhile, in the running process, a workpiece can be maintained and replaced conveniently, a transmission piece is simple in structure, operation is easy, mounting and demounting functions can be achieved conveniently, and an energy saving effect is achieved.

Description

technical field [0001] The invention belongs to the field of bag-making machine manufacturing, and in particular relates to a heat-sealing transmission structure of a bag-making machine. Background technique [0002] The bag making machine is a special equipment for making packaging bags, which is widely used in the production of packaging bags made of various plastics, paper and other materials. The process of forming a packaging bag by a high-speed bag making machine is: guiding the upper film and the lower film to be transported separately, overlapping the upper and lower films at a suitable position, and the overlapped films are heat-sealed longitudinally and transversely to form an integrated structure of multiple small bags, and finally separated. Cut into multiple pouches. The heat sealing mechanism is used to heat seal the upper and lower films into one body to form a bag structure, which is an essential part of the bag making machine. The traditional heat-sealing ...

AI Technical Summary

Problems solved by technology

The traditional heat-sealing mechanism is generally only suitable for a single heat-sealing, and its heat-sealing speed is slow and the efficiency is low; there have been high-speed heat-sealing devices, and its advantage is that it can realize multi-row heat-sealing, but its disadvantage is that the heat-sealing plate and The structure of the heat-sealing platen is complicated, it is not easy to replace, and the heat-sealing stability is not high
