Embodiment Construction

[0014] Such as figure 1 , The invention is a heat sealing device of a bag making machine. Its function is to heat seal the upper and lower layers of film passing through it. It mainly consists of a lower mold assembly, an upper mold assembly, a linkage rod 20 and a pneumatic pressure device (a cylinder) 1 in the figure.

[0015] The lower mold assembly is composed of polytetrafluoroethylene high temperature resistant cloth layer 5 , silicon rubber pad 10 , lower mold 11 , lower connecting plate 12 and lower beam 13 sequentially connected from top to bottom. The two sets of lower beams are installed on the surface of the bag making machine. By adjusting the hand wheel, gear shaft, gear and rack, the whole heat sealing device can be moved forward and backward. The lower mold 11 can be made into a plane or a bag shape as required, and the upper plane must meet the flatness requirements. The upper mold assembly consists of polytetrafluoroethylene high temperature resistant clo...

Abstract

The heat-sealing device of bagging machine comprises lower die component, upper die component, coupled bar and pneumatic pressure device, the lower end of the coupled bar is connected with power source, its upper end is connected with pneumatic pressure device, its lower die component includes lower die, lower connecting plate and lower cross beam which are connected together from top to bottom, and the upper die component includes upper die, upper die fixing plate and upper cross beam which are connected together from bottom to top. The upper cross beam is connected with pneumatic pressure device, and the upper die is equipped with heating element. Said invention can be used for heat-sealing various plastic bags, and its structure is simple and operation is convenient.

Description

Technical field: [0001] The invention relates to a bag making machine. Specifically relates to a heat sealing device of a bag making machine. It is used to heat seal the upper and lower layers of materials. It belongs to the technical field of bag making machinery. Background technique: [0002] With the continuous improvement of people's material life quality, the requirements for packaging bags for daily necessities and food are getting higher and higher. At present, the beautiful and generous special-shaped bags (bag type non-square or rectangular) with their own characteristics are very popular among customers. There is an urgent need for a bag making machine that can meet this need. The general bag making machine uses vertical and horizontal electric heating knives to heat, press and seal plastic films or composite films (such as paper-plastic composite, aluminum-plastic composite, etc.). Due to the separate process and the change of film tension, it is difficult t...
