Heat sealing mechanism of film

Abstract

The invention discloses a film heat sealing mechanism, which belongs to the field of film processing machinery and equipment. The invention includes a fixed bracket, a heat-sealing motor, a drive shaft, a rotating shaft, a rotating disk, a translation bracket and a heat-sealing plate. The two sides of the fixed bracket are respectively connected with a driving shaft and a rotating shaft for vertical rotation, and the upper and lower sides of the driving shaft are respectively horizontal. An upper drive gear and a lower drive gear are provided, and an upper output gear and a lower output gear are arranged horizontally on the upper and lower sides of the adjustment sleeve. The adjustment sleeve and the rotating shaft are connected and fixed by an adjustment screw. The rod is matched with a rotation guide groove, a connecting plate is arranged between one side of the translation block and the guide plate, and a heat sealing plate is horizontally arranged at one end of the support rod. The invention has a reasonable structural design, can quickly, efficiently, stably and evenly drive a heat-sealing plate to heat-seal the film, and can adjust the heat-sealing rate of the film as required to meet the needs of production and use.

Description

technical field [0001] The invention belongs to the field of film processing machinery and equipment, and in particular relates to a film heat-sealing mechanism. Background technique [0002] At present, in modern industrial production, the packaging of powder materials has developed from manual packaging to semi-automatic and fully automatic mechanical packaging stages relying on packaging machines. The structure of packaging machines is also constantly updated and changed. The existing powder packaging machines can automatically The film is made into a bag and the powder is filled into the bag. During the film bag making process, the film needs to be heat-sealed with a heat-sealing mechanism so that the material in the bag does not leak out. Heat-sealing bags are widely used in In the fields of daily chemical product packaging and food and drug packaging, since the heat seal part of the packaging bag is most likely to leak when the product is filled, and most of the damage...

AI Technical Summary

Problems solved by technology

The structure of the existing heat-sealing mechanism is complicated and the operation is cumbersome. It is difficult to efficiently and stably drive the heat-sealing plate to heat-press and seal the film. Moreover, the bag-making rate of the existing heat-sealing mechanism is fixed, and it is difficult to adjust the heat-sealing bag-making rate according to the needs of use. Speed, the scope of application is narrow, it is difficult to improve the efficiency and quality of bag making, and cannot meet the needs of production and use
