Delay type heat sealing auxiliary equipment for plastic packaging bag sealing

Abstract

The invention relates to the technical field of plastic packaging bag sealing equipment, in particular to delay type heat sealing auxiliary equipment for plastic packaging bag sealing. The delay type heat sealing auxiliary equipment comprises a treatment table, a driving shaft is rotatably connected to the interior of the left side of the interior of the treatment table, and a movable sliding plate is connected to the exterior of the right end of the driving shaft in an engaged manner; and a crank connecting rod is hinged to the upper surface of the movable sliding plate, a pulling rope is fixedly connected to the rear surface of the crank connecting rod, and a positioning sliding plate is fixedly connected to the upper end of the pulling rope. The temperature of a heat sealing plate is controlled through a sliding rheostat, so that the temperature of the heat sealing plate cannot scald a packaging bag; and an extrusion transmission plate drives a transmission pressing plate at the right side to restore to the original position, at the moment, an extension spring is linearly restored, and then the heat sealing plate is restored, so that the heat sealing time is possibly well prolonged, the effect of improving the heat sealing efficiency of the equipment is achieved, the phenomenon of heat sealing cracking at the heat sealing position is avoided, and the heat sealing success rate of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of plastic packaging bag sealing equipment, in particular to a delay-type heat-sealing auxiliary equipment used for sealing plastic packaging bags. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. It is widely used in daily life and industrial production. In the process of plastic bag packaging, after placing items in the plastic bag, the opening edge needs to be heat-sealed. For small plastic bags, a simple heat-sealing device can be used for heat-sealing That is enough, but for the large plastic bags that have been placed in the pallet box, the mouth of the plastic bag needs to be fixed before heat sealing, so that the heat sealing can be better completed. [0003] However, when the existing equipment heat-seals the packaging bag, the heat-sealing effect is poor, whic...

Problems solved by technology

[0003] However, when the existing equipment heat-seals the packaging bag, the heat-sealing effect is poor, which causes the heat-sealed part to crack easily, which may cause heat-sealing failure, affect the heat-sealing effect of the equipment, and cannot properly The heat-sealed area is flattened and wrinkled-removed, which may affect the appearance of the heat-sealed area; therefore, those skilled in the art provide a time-delayed heat-sealing auxiliary equipment for plastic packaging bag sealing to solve the problems raised in the above-mentioned background technology.
