[0026] When the bag film needs to be heat-sealed, the tension of the tension component is adjusted by using the adjustment component according to the length of the bag film, and the bag film is wrapped around the tension component to form an M-shaped state. The end of the bag film that starts to be heat-sealed is placed between the two conveyor belts 201 through the guide mechanism 300, and the motor 208 is started to drive the two conveyor belts 201 to rotate through the synchronous belt 207. Both conveyor belts 201 are provided with tensioning wheels 203. The conveyor belt 201 drives the bag film to move, and the bag film is heated by the heating block 204 to achieve heat sealing.

[0027] By setting up a tension component, the bag film can be tightened to assist in feeding. The tension of the tension component can be adjusted by using an adjustment component to expand the use range of the equipment. The guide mechanism 300 can make the bag film move more stably, thereby improving the stability of the equipment.

[0028] See also Figure 1-Figure 6 As shown, the tension assembly includes a first tensioning roller 404 and a second tensioning roller 406, a first mounting frame 403 is symmetrically provided on the vertical plate 100, the first tensioning roller 404 is rotatably provided on the first mounting frame 403, a second mounting frame 405 is provided on the vertical plate 100 between the two first mounting frames 403, the second tensioning roller 406 is rotatably provided on the second mounting frame 405, and the second mounting frame 405 and the two first mounting frames 403 are distributed in an isosceles triangle.
