[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment: an automatic film laminating machine, comprising a body 1 and a bracket 10, a preheating box 3 is fixedly connected to the left end of the front side of the top wall of the body 1, a heat sealing machine 4 is fixedly connected to the right end of the front side of the top wall of the body 1, a film frame 5 is fixedly connected to the left side of the top wall of the heat sealing machine 4, a pressure wheel 6 is installed in the middle of the front side of the outer wall of the heat sealing machine 4, a bottom wheel 7 is installed at the bottom of the front side of the outer wall of the heat sealing machine 4, a limiting rod 8 is fixedly connected to the left end of the front side of the outer wall of the heat sealing machine 4, a heating cover 9 is fixedly connected to the right end of the front side of the outer wall of the heat sealing machine 4, a plurality of chain frames 11 are fixedly connected to the top of the bracket 10 at equal intervals, a pretreatment mechanism 2 is fixedly connected to the middle of the left side of the outer wall of the bracket 10, and the pretreatment mechanism 2 is used for pretreatment of the zipper that needs to be film-laminated; a plurality of fixed columns 12 are fixedly connected to the bottom of the bracket 10 at equal intervals, and a universal wheel 13 is installed at the bottom of the fixed column 12;

[0041] Specifically, during the automatic film lamination process, the preheating box 3 is started. As the preheating box 3 is started, the zipper will slowly move from the chain frame 11 to the inside of the preheating box 3 for preheating treatment. After the preheating is completed, the zipper will continue to move and eventually reach the top position of the bottom wheel 7. During this process, the limit rod 8 presses on the zipper to ensure that the input direction of the zipper is precisely controlled. The thermal transfer film will start to move from the film frame 5 and eventually reach the bottom position of the pressure wheel 6. The cooperation between the pressing wheel 6 and the bottom wheel 7 acts on the thermal transfer film and the zipper, so that the thermal transfer film can be evenly attached to the surface of the zipper. The heating cover 9 heats the pressing wheel 6. With the assistance of the heating cover 9, the temperature of the pressing wheel 6 will be increased, thereby performing secondary heating on the zipper and the thermal transfer film, ensuring a better heat-sealing effect, making the combination of the thermal transfer film and the zipper surface more firm and not easy to fall off, ensuring that the quality of the final product reaches the best state; the universal wheel 13 can be installed at the bottom of the bracket 10 through the fixing column 12, increasing the flexibility of the bracket 10, thereby improving the practicality of the entire equipment.

[0042] Reference Figure 1 、 Figure 3 and Figure 5 The pretreatment mechanism 2 includes a fixed box 201, which is fixedly connected to the middle part of the left side of the outer wall of the bracket 10, and a motor 202 is fixedly connected to the middle part of the front side of the inner wall of the bracket 10. The output end of the motor 202 is fixedly connected to a worm 203. The left and right ends of the front side of the inner wall of the fixed box 201 are rotatably connected to roller brushes 204. The middle part of the outer wall of the roller brush 204 is fixedly connected to a worm gear 205. The worm gear 205 is meshed with the worm 203. A spray pot 206 is fixedly connected to the middle and lower part of the left side of the outer wall of the bracket 10, and the top of the spray pot 206 is connected to a nozzle 207; the left and right sides of the bottom of the body 1 are fixedly connected to support columns 14, and the bottom of the support column 14 is fixedly connected to an anti-slip pad 15;

[0043] Specifically, before the zipper enters the preheating box 3 from the chain frame 11, it will first pass through the pretreatment mechanism 2 for a pretreatment step, press the spray bottle 206, so that the liquid inside the spray bottle 206 is evenly sprayed onto the surface of the zipper through the nozzle 207, and the zipper is moistened, and the motor 202 is started. The motor 202 starts to work, and its power is transmitted to the worm 203, so that the worm 203 starts to rotate. The rotation of the worm 203 will drive the worm gear 205 engaged with it to rotate together. During the rotation of the worm gear 205, the roller brush 204 will carefully clean the surface of the zipper, effectively removing dust and impurities on the surface of the zipper, thereby preventing these impurities from affecting the heat sealing effect and ensuring the quality of the heat sealing; the support column 14 is used to support the body 1 to improve the stability of the body 1, and the anti-slip pad 15 is used to prevent the support column 14 from sliding on the ground, reducing unnecessary risks. The model of the motor 202 is 5RK90RGU-CF.

[0044] Reference Figure 1and Figure 3 The top right side of the outer wall of the body 1 is fixedly connected with a fixing plate 16, and the top of the fixing plate 16 is fixedly connected with a limiting ring 17; the four corners of the outer wall of the body 1 are threadedly connected with an anti-collision shell 20, and the middle part of the outer wall of the anti-collision shell 20 is threadedly connected with a bolt 21;

[0045] Specifically, the fixing plate 16 has the function of firmly fixing the limiting ring 17. Through the adjustment of the limiting ring 17, the specific position of the zipper after the heat sealing treatment can be accurately controlled, which is convenient for the staff to collect and organize the work in the later stage. The design of the anti-collision shell 20 can effectively reduce the possible injuries that the staff may suffer when colliding with the body 1, ensuring the safety of operation. Through the connection of the bolts 21, the anti-collision shell 20 can be easily installed and quickly replaced when necessary, ensuring the maintenance convenience and service life of the equipment.

[0046] Reference Figure 1 and Figure 4 , a rotating shaft 18 is fixedly connected to the middle upper part of the front side of the outer wall of the preheating box 3, and the other end of the rotating shaft 18 is rotatably connected to the cover plate 19; an accessory box 22 is fixedly connected to the left end of the rear side of the top wall of the body 1, and a box cover 23 is installed on the top of the accessory box 22;

[0047] Specifically, by rotating the shaft 18, the staff can easily open the cover 19, so that when the equipment preheating box 3 fails, maintenance work can be conveniently carried out. In addition, the setting of the accessory box 22 greatly improves the storage efficiency of parts and tools, and effectively reduces the loss of tools. The integrity of the accessory box 22 can be achieved through the box cover 23 to ensure that all accessories and tools can be properly kept.

[0048] Working principle: During the automatic film lamination process, the preheating box 3 is started. As the preheating box 3 is started, the zipper moves from the chain frame 11 to the inside of the preheating box 3 for preheating. After the zipper is preheated, it reaches the top of the bottom wheel 7. The limit rod 8 presses on the zipper to help control the input direction of the zipper. The heat transfer film moves from the film frame 5 to the bottom of the pressing wheel 6. The pressing wheel 6 and the bottom wheel 7 adhere to the surface of the zipper. The heating cover 9 is used to increase the temperature of the pressing wheel 6 and perform secondary heating on the zipper and the heat transfer film, thereby achieving a better heat sealing effect.

[0049] Before the zipper enters the preheating box 3 from the chain frame 11, it will be pretreated by the pretreatment mechanism 2. Press the spray bottle 206 so that the liquid inside the spray bottle 206 is sprayed onto the surface of the zipper through the nozzle 207 to moisten the zipper. Start the motor 202. Under the action of the motor 202, the worm 203 starts to rotate, thereby driving the meshing worm gear 205 to rotate. After the worm gear 205 rotates, the roller brush 204 cleans the surface of the zipper to avoid poor heat sealing effect due to dust on the surface of the zipper. The fixed box 201 can reduce the dust flying during the cleaning process, which is more environmentally friendly.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
