A coating plate is installed in the center of the bottom of the horizontal plate, and a coating platform is installed below the coating plate. A coating base is installed on the top of the coating platform, and two sets of support legs are installed at the bottom of the housing. This utility model, with its coating plate, ensures the contact area between the printed material and the label, effectively reducing the pressing time, thereby ensuring complete bonding between the film and the label.

[0004] Although the above-mentioned equipment can perform anti-counterfeiting film application, it is inefficient in batch feeding of workpieces to be coated, which reduces the speed of applying anti-counterfeiting film to batch workpieces. Therefore, there is an urgent need for an anti-counterfeiting film coating mechanism to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of an anti-counterfeiting film pasting mechanism, including a support base 7. A feeding groove 8 is provided at the center of the upper surface of the support base 7. Conveying guide rollers 6 are rotatably engaged at both the front and rear of the support base 7. The two sets of conveying guide rollers 6 are connected by a conveyor belt 2. A servo motor 1 is provided on the side surface of the support base 7, directly opposite the conveying guide rollers 6.

[0023] The guide fixture 5 is provided in multiple sets and is equidistantly arranged on the upper end face of the conveyor belt 2. Three sets of workpiece slots 4 are equidistantly opened on the upper end face of the guide fixture 5. The guide fixture 5 is used for feeding and positioning.

[0024] The adhesive device 3 is fixedly installed at the center of the upper end face of the support base 7. The adhesive device 3 is used to heat-melt and adhere the anti-counterfeiting film.

[0025] The pasting device 3 includes an alignment guide seat 31. A mini cylinder 32 is provided at the center of the upper end face of the alignment guide seat 31, and a guide slide 36 is provided at the output end of the mini cylinder 32. Three sets of hot melt modules 35 are equidistantly arranged on the lower end face of the guide slide 36. Anti-counterfeiting film guide rollers 37 are rotatably engaged on both sides of the inner end face of the alignment guide seat 31. Synchronous pulleys 33 are provided on the front end faces of the two sets of anti-counterfeiting film guide rollers 37, and the two sets of synchronous pulleys 33 are meshed and connected by a synchronous belt 34. A reduction motor 38 is provided on the rear end face of the alignment guide seat 31 facing the anti-counterfeiting film guide rollers 37.

[0026] The inner end face of the conveyor belt 2 is bonded to the upper end face of the feeding chute 8, which provides sufficient support for the subsequent hot melt module 35 to press and bond the anti-counterfeiting film to the injection molded parts.

[0027] The lower end face of the hot melt module 35 is directly opposite the workpiece slot 4, which can effectively improve the accuracy of the subsequent hot melt module 35 in positioning and bonding the anti-counterfeiting film to the injection molded part inside the workpiece slot 4.

[0028] The bottom of the inner end face of the alignment guide seat 31 is provided with a positioning guide groove, and the positioning guide groove is slidably connected to the guide slide 36. The positioning guide groove can provide sufficient guidance and positioning foundation for the guide slide 36, thereby improving the efficiency of the hot melt module 35 in bonding the anti-counterfeiting film to the injection molded part.

[0029] The upper end face of the guide slide 36 is provided with two sets of linear slide shafts, and the guide slide 36 is slidably engaged with the inner end face of the alignment guide 31 through the linear slide shafts. The two sets of linear slide shafts can provide sufficient axial guiding stability for the guide slide 36, and then through the subsequent guide slide 36, drive the three sets of hot melt modules 35 to bond the anti-counterfeiting film with stability.

[0030] Working principle: Before applying the anti-counterfeiting film to the outside of the injection molded part, the operator can position the required anti-counterfeiting film roll inside one side of the anti-counterfeiting film guide roller 37, and then position the anti-counterfeiting film head inside the other side of the anti-counterfeiting film guide roller 37, so that the anti-counterfeiting film strip is horizontally transferred between the two sets of anti-counterfeiting film guide rollers 37, which facilitates the subsequent cyclic feeding and pasting of the anti-counterfeiting film. Then, the operator can position the injection molded part feeding module to the feeding end of the support card seat 7, which facilitates the feeding operation of multiple injection molded parts. When applying the anti-counterfeiting film to the injection molded part, the operator can simultaneously start the servo motor 1 and the reduction motor 38. First, the servo motor 1 can intermittently drive the injection molded part inside the guide fixture 5 and the workpiece slot 4 through the two sets of conveying guide rollers 6 to position the anti-counterfeiting film. At the lower part of the pasting device 3, the reduction motor 38 is then started. The reduction motor 38 can drive the two sets of anti-counterfeiting film guide rollers 37 to rotate synchronously through the two sets of synchronous pulleys 33 and synchronous belts 34. This allows the two sets of anti-counterfeiting film guide rollers 37 to export the anti-counterfeiting film from the upper part of the material strip and position it on the upper part of the three sets of workpiece slots 4, completing the positioning operation before pasting the anti-counterfeiting film. Then, the mini cylinder 32 is started, which can drive the guide slide 36 to move down. When the guide slide 36 moves down, it can drive the three sets of hot melt modules 35 to align the anti-counterfeiting film until the anti-counterfeiting film is pressed onto the injection molded part inside the workpiece slot 4. At this time, the hot melt module 35 can melt the connection point between the anti-counterfeiting film and the material strip, and at the same time press and paste the anti-counterfeiting film onto the upper part of the injection molded part.
