Packaging heat sealing machine for sealing packaging bag

Abstract

The invention discloses a packaging heat sealing machine for sealing a packaging bag. The packaging heat sealing machine comprises a heat sealing machine body which is mainly formed by a hydraulic cylinder, a telescopic rod, a connecting rod, a base, a melt pressure plate and a heat sealing plate; a groove is formed in the heat sealing plate, and slide slots are formed in two sides of the groove; locating columns are fixedly connected to two sides of the base, the locating columns are slidably connected to sliding pieces, springs are arranged between the sliding pieces and a fixed plate, the bottom of the hydraulic cylinder is connected to the telescopic rod, the bottom of the telescopic rod is fixedly connected to a connecting piece, the bottom of the connecting piece is fixedly connected to a sliding plate, the bottom of the sliding plate is fixedly connected to the melt pressure plate, connecting rods are rotatably connected to two sides of the melt pressure plate, pressure rolls are arranged at the tail ends of the connecting rods, and the pressure rolls are rotatably connected through a rotary shaft. The heat sealing machine disclosed by the invention can avoid the condition that the sealing position is inaccurate as the melt pressure plate deviates in position after long-term use. The heat sealing machine sealing the packaging bag can avoid the condition that the buckle of the packaging bag wrinkles, and the sealing quality is good.

Description

technical field [0001] The invention relates to a packaging device, in particular to a packaging heat-sealing machine for sealing packaging bags. Background technique [0002] In the production of enterprises, it is often necessary to heat seal the mouth of the packaging bag to prevent the items from leaking out of the packaging bag, and the items are sealed inside the packaging bag to facilitate the transportation of the items. [0003] During the hot air process of the packaging bag, a packaging heat sealing machine is required. The packaging heat sealing machine is a device that fuses the opening of the bag by heating. It is used to heat seal the opening of the packaging bag. The packaging heat sealing machine is used for the production of enterprises It provides convenience and is conducive to the normal operation of the production line. [0004] However, after the current packaging heat-sealing machine is used for a long time, the position of the fusion plate is prone ...

AI Technical Summary

Problems solved by technology

[0004] However, after the current packaging heat-sealing machine is used for a long time, the position of the fusion plate is prone to be cheap, resulting in inaccurate heat-sealing positions, and when heat-sealing, the opening of the packaging bag is prone to wrinkles, the heat-sealing efficiency is low and the heat-sealing quality is poor , not beautiful enough, affecting the sales of food products
