The servo motor 301 and the resistance heating rod 308 are started, and the output shaft of the servo motor 301 drives the roller 310 to rotate. The roller 310 rotates to rub the outer surface of the woven bag, so that the woven bag slides on the upper surface of the fixed plate 309. At the same time, the resistance heating rod 308 heats up, so that the fixed plate 309 can heat the woven bag, so that the woven bag softens, and then under the pressure of the resistance heating rod 407, the surface of the woven bag is squeezed flat, so that the woven bag can be better fused together.

[0040] Reference Figures 1 to 5 In one aspect of the present embodiment, the heat sealing mechanism 4 includes a fixed shell 402 fixedly connected to the upper surface of the base 1, the upper surface of the fixed shell 402 is fixedly connected to a first electric telescopic rod 401, the lower end of the first electric telescopic rod 401 passes through the inner side surface of the fixed shell 402 and is fixedly connected to a limiting plate 406, and the lower surface of the limiting plate 406 is fixedly connected to a resistance heating rod 407.

The first electric telescopic rod 401 and the resistance heating rod 407 are started, so that the outer surface of the rubber roller 408 contacts the outer surface of the woven bag, and the limit spring 306 is deformed under the pressure of the first electric telescopic rod 401, so that the rubber roller 408 squeezes the outer surface of the woven bag, so that the woven bag is tightened, and at the same time, the lower surface of the resistance heating rod 407 is in contact with the outer surface of the tightened woven bag, so as to accelerate the fusion speed between the woven bags.

[0044] All electrical equipment in this solution are powered by an external power supply.

[0045] Working principle: When in use, first roll the woven bag onto the roller on the unwinding device 2, then pass one end of the woven bag body through the limit roller group 6, then pull the connecting plate 304, so that the connecting plate 304 drives the connecting column 305 and the pressure plate 307 to move upward, causing the limit spring 306 to deform, and then pass the woven bag from under the pressure plate 307, so that the woven bag passes from under the roller shaft 310 and the resistance heating rod 407, press the button on the control panel 302, start the servo motor 301 and the resistance heating rod 308, the output shaft of the servo motor 301 drives the roller shaft 310 to rotate, and the roller shaft 310 rotates to rub the outer surface of the woven bag, so that the woven bag slides on the upper surface of the fixed plate 309. At the same time, the resistance heating rod 308 generates heat, so that the fixed plate 309 can heat the woven bag to soften the woven bag. Then, under the pressure of the resistance heating rod 407, the surface of the woven bag is squeezed flat, so that the woven bag can be better fused together, which improves the heat-sealing quality of the woven bag to a certain extent. The woven bag is heated and shaped by the rubber roller 408 and the resistance heating rod 407, so that the outer surface of the woven bag is smooth and smooth, further improving the quality of the woven bag.

[0046] When the woven bag is heat-sealed, the first electric telescopic rod 401 and the resistance heating rod 407 are started, and the lower end of the first electric telescopic rod 401 drives the limit plate 406 to move downward, so that the outer surface of the rubber roller 408 contacts the outer surface of the woven bag, and the spring sheet 409 is deformed under the pressure of the first electric telescopic rod 401, so that the rubber roller 408 rolls on the upper surface of the woven bag. Since the rubber roller 408 is made of rubber material, the friction between the rubber roller 408 and the woven bag is increased. When the rubber roller 408 rolls, it squeezes the outer surface of the woven bag. The woven bag is tightened by the two sets of symmetrical rubber rollers 408, and the lower surface of the resistance heating rod 407 fits with the outer surface of the woven bag, thereby accelerating the fusion speed between the woven bags. Then the second electric telescopic rod 403 and the resistance heating wire 405 are started, and the upper end of the second electric telescopic rod 403 drives the lifting plate 404 and the resistance heating wire 405 to slide upward, so that the outer surface of the resistance heating wire 405 is dynamically fitted with the woven bag, and the high temperature generated by the resistance heating wire 405 can melt the outer surface of the woven bag, thereby reducing the occurrence of splitting of the outer surface of the woven bag.
