Upper pressure plate structure for heat sealing device of bag making machine

Abstract

The invention relates to an upper pressure plate structure for a heat sealing device of a bag making machine. The upper pressure plate structure comprises a pressure plate support body, wherein the lower surface of the pressure plate support body is fixedly connected to a pressure plate group, and the upper surface of the pressure plate support body is fixedly connected to an installation block; the pressure plate support body is provided with a downward groove, first support blocks and second support blocks, which are arranged in pairs, are formed in the groove, and the paired second support blocks are arranged between the paired first support blocks; end blocks are respectively packaged on the two ends of the pressure plate support body, and each end block is provided with a locking regulating wheel; a regulating rod penetrates the end blocks and the pressure plate support body, gears are respectively arranged on two ends of the regulating rod, and each gear is arranged on the outer side of the corresponding end block. According to the upper pressure plate, by adopting the two groups of pressure plate structures, the heat sealing efficiency is improved; through setting an adjusting screw and the regulating rod, the heat sealing intensity and the heat sealing position are conveniently adjusted, and the operation is simple; the pressure plate and the pressure plate support body are connected through a spring, so that the elastic heat sealing is achieved, the spring is hidden in the pressure plate support body, and the structure is compact; the pressure plate has the advantages of simple structure and convenience for assembly.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to 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 device is used to heat seal the upper and lower films to form a bag structure, which is an essential part of the bag making machine. The traditional heat-sealing device is generally only suitable for a single heat-sealing, and its hea...
