Technical Field
[0001] This utility model belongs to the technical field of adhesive application devices, specifically relating to an adhesive application device for plastic parts. Background Technology
[0002] Labeling is a process in which labels are pasted or adhered to predetermined positions using mechanical equipment to achieve packaging purposes. Sports apparel and sporting goods require labeling after production. Typically, the trademarks on sports apparel and sporting goods are made of plastic. Before labeling, double-sided self-adhesive tape needs to be pasted on one side of the plastic trademark, and then the plastic trademark is pasted onto the target object using the double-sided self-adhesive tape.
[0003] When applying adhesive to plastic parts, a pressure roller is needed to firmly adhere the double-sided self-adhesive to the plastic parts. The commonly used adhesive application equipment uses a pressure roller made of stainless steel or other rigid materials. During the pressing process, the pressure roller and the plastic parts make tangential line contact, resulting in a short contact time and poor pressing effect. Utility Model Content

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figure 1 and 2 As shown, a plastic part bonding device includes a base 1 and a winding assembly 2. A first conveyor belt 11 and a second conveyor belt 12 are provided at the top of the base 1. The winding assembly 2 is fixedly connected to the top of the base 1. An unwinding assembly 3 is provided at the middle of the top of the base 1. Both the winding assembly 2 and the unwinding assembly 3 are located above the first conveyor belt 11.

[0022] According to the above structure, in use, the double-sided adhesive roll is placed on the unwinding assembly 3, and the trademark plastic part is placed on the first conveyor belt 11. After being conveyed by the first conveyor belt 11, the plastic part moves forward. When it moves to the bottom of the unwinding assembly 3, the unwinding assembly 3 applies the adhesive tape to the top of the plastic part. The oil film of the double-sided adhesive is recovered by the winding assembly 2. The plastic part after applying the adhesive passes between the bonding assembly 4 and the second conveyor belt 12, further pressing the adhesive firmly onto the plastic part and improving the adhesion.
[0023] like Figure 2-4 As shown, the unwinding assembly 3 includes two unwinding support frames 31 that are fixedly connected to the top sides of the base 1 respectively. A pressure roller 32 is rotatably connected between the two unwinding support frames 31. A second servo motor 34 is fixedly connected to one end of one of the unwinding support frames 31. The output shaft of the second servo motor 34 is fixedly connected to one end of the pressure roller 32. An unwinding roller 33 is rotatably connected to the top of the other unwinding support frame 31. An extension plate 35 is fixedly connected to one side of each of the two unwinding support frames 31. Two corresponding guide rollers 36 are rotatably connected between the two extension plates 35.
[0024] According to the above structure, in use, the double-sided tape roll is placed on the unwinding roller 33, the double-sided tape is passed between the two guide rollers 36, the oil film of the double-sided tape is torn off, and the double-sided tape is passed through the bottom end of the pressure roller 32. When the plastic part is conveyed to the bottom end of the pressure roller 32, the pressure roller 32 presses the double-sided tape onto the plastic part, thereby applying adhesive to the top of the plastic part.
[0025] like Figure 2 As shown, the winding assembly 2 includes a winding support frame 21 fixedly connected to the top of the base 1. A winding roller 23 is rotatably connected to one side of the top of the winding support frame 21, and a first servo motor 22 is fixedly connected to the other side of the top of the winding support frame 21. The output shaft of the first servo motor 22 is fixedly connected to one end of the winding roller 23.
[0026] According to the above structure, the torn oil film bypasses the top guide roller 36 and wraps around the take-up roller 23. During use, the first servo motor 22 drives the take-up roller 23 to rotate, thereby recovering the oil film.
[0027] like Figure 3-5 As shown, the bonding component 4 includes two sets of corresponding mounting plate groups. Each set of mounting plate groups includes two mounting plates 41 respectively set on both sides of the top of the base 1. A pressing component 44 is provided between the two mounting plates 41 in each set of mounting plate groups. The pressing component 44 includes a rotating shaft 445 rotatably connected between the two mounting plates 41. A flexible roller 441 is fixedly bonded to the side wall of the rotating shaft 445. The side wall of the flexible roller 441 is pressed against the top of the second conveyor belt 12. A heating element 442 is embedded in the edge of the flexible roller 441. The heating element 442 includes two layers of metal foil 443 with corresponding color numbers. A heating resistance wire 444 is fixedly connected between the two layers of metal foil 443.

A third servo motor 43 is fixedly connected to one end of one of the mounting plates 41. The output shaft of the third servo motor 43 is fixedly connected to one end of one of the rotating shafts 445.
[0028] According to the above structure, the plastic part after being coated with adhesive passes between the bottom end of the flexible roller 441 and the top end of the second conveyor belt 12. The flexible roller 441 is made of flexible materials such as latex or rubber. The flexible roller 441 is pressed against the top end of the second conveyor belt 12. The bottom of the flexible roller 441 that contacts the second conveyor belt 12 is deformed into a flat shape, thereby increasing the contact area with the double-sided adhesive. During pressing, the heating resistance wire 444 is energized and heats up. The edge of the flexible roller 441 is heated and rises in temperature. This not only applies a certain pressure to the plastic part, but also heats the double-sided adhesive, improving its adhesion and making it adhere more tightly to the plastic part.
[0029] The working principle of this utility model is as follows: During use, the double-sided adhesive roll is placed on the unwinding assembly 3, and the trademark plastic part is placed on the first conveyor belt 11. Conveyed by the first conveyor belt 11, the plastic part moves forward, and the double-sided adhesive roll is placed on the unwinding roller 33. The double-sided adhesive is passed between the two guide rollers 36, the oil film of the double-sided adhesive is torn off, and the double-sided adhesive is passed through the bottom end of the pressure roller 32. When the plastic part is conveyed to the bottom end of the pressure roller 32, the pressure roller 32 presses the double-sided adhesive firmly onto the plastic part, thus applying adhesive to the top of the plastic part. The torn-off oil film bypasses the top guide roller 36 and wraps around the take-up roller 23. During use, the first servo motor 22 drives... The rotating take-up roller 23 rotates to recover the oil film. The plastic part after being coated with adhesive passes between the bottom end of the flexible roller 441 and the top end of the second conveyor belt 12. The flexible roller 441 is made of flexible materials such as latex or rubber. The flexible roller 441 is pressed against the top end of the second conveyor belt 12. The bottom of the flexible roller 441 that contacts the second conveyor belt 12 is deformed into a flat shape, thereby increasing the contact area with the double-sided adhesive. During pressing, the heating resistance wire 444 is energized and heats up. The edge of the flexible roller 441 is heated and rises in temperature. This not only applies a certain pressure to the plastic part, but also heats the double-sided adhesive, improving its adhesion and making it adhere more tightly to the plastic part.
