Description

Technical Field

[0001] This utility model relates to the technical field of paint protection film production equipment, and in particular to a gluing machine for molding thermoplastic polyurethane paint protection film. Background Technology

[0002] Paint protection film is a high-performance, new type of environmentally friendly film widely used in the automotive window tinting and maintenance industry. It is a common name for transparent paint protection film, which has super toughness and can isolate the car paint from the air after application, providing long-lasting protection for the paint. Paint protection film is a thermoplastic polyurethane film (TPU). During the production process, adhesive needs to be applied to the surface of the TPU substrate.

[0003] In existing technologies, it is inconvenient to evenly apply adhesive to the film surface and to smooth the film. Excess adhesive is also difficult to recycle. Therefore, we propose a gluing machine for forming thermoplastic polyurethane invisible car wraps. According to a search, patent publication number CN218048655U discloses a gluing machine for forming thermoplastic polyurethane invisible car wraps. Its technical solution includes a box body, an adhesive tank fixedly connected inside the box body, an electric heating plate and a sponge pad fixedly connected inside the adhesive tank, etc. An auxiliary gluing mechanism is provided inside the box body. This gluing machine can solve the technical problems existing in the prior art.

[0004] However, the aforementioned patent still has some drawbacks. When applying glue, the sponge pad absorbs the glue and then spreads it onto the outer wall of the rubber roller. However, since there is a gap between the rubber roller and the glue tank, when the equipment is not in use, the glue absorbed in the sponge will drip onto the rubber roller through the sponge pad and continue to drip down the rubber roller, resulting in glue waste. Moreover, the glue tank is fixed inside the box, making it inconvenient to replenish the glue tank, thus lacking practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a glue application machine for thermoplastic polyurethane invisible car wrap molding that can prevent continuous glue dripping, avoid glue waste, facilitate glue replenishment in the glue tank, and improve practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gluing machine for forming thermoplastic polyurethane invisible car wraps, comprising a housing and a gluing mechanism. A motor is fixedly installed at the front end of the housing, and a rotating shaft is rotatably installed on the housing. The front end of the rotating shaft is fixedly connected to the output end of the motor. A rubber roller is fixedly sleeved on the rotating shaft. The gluing mechanism includes a glue tank and two sets of baffles. An opening is provided at the top of the housing. The glue tank is slidably installed on the housing by cooperating with the opening. Two sets of electric lifting rods are symmetrically fixedly installed at the top of the housing. Connecting plates are fixedly provided at both ends of the glue tank. The output ends of the two sets of electric lifting rods are respectively fixedly connected to the two sets of connecting plates. A feeding port is provided at the top of the glue tank, and a material cover is installed on the top of the feeding port. The glue tank has a glue outlet at the bottom, with guide grooves at both ends. Two sets of baffles are fixed with guide rails at both ends. The two sets of baffles are symmetrically mounted on the glue outlet through the cooperation of the guide rails and guide grooves. A sponge pad and an electric heating plate are fixedly connected inside the glue tank. The bottom of the sponge pad contacts the top of the two sets of baffles. Two sets of fixing plates are fixedly connected between the front and rear inner walls of the tank. The two sets of fixing plates are symmetrically distributed on both sides of the rubber roller. Two sets of transmission plates are symmetrically hinged at the bottom of the two sets of baffles. The bottom ends of the two sets of transmission plates on the left and the two sets of transmission plates on the right are respectively hinged to the top of the two sets of fixing plates. A long plate is fixedly connected to the bottom of the fixing plate on the left side of the rubber roller. A glue brush is fixedly installed at the bottom of the long plate.

[0008] Preferably, an observation window is fixedly provided on the top of the glue tank.

[0009] Preferably, a handle is fixedly provided at the top of the material cover.

[0010] Preferably, a protective cover is installed at the front end of the housing.

[0011] Preferably, ribs are fixedly connected to both ends of the glue tank and the bottom ends of the two sets of connecting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During glue application, by activating the electric lifting rod, the electric lifting rod pushes the glue tank downward through the connecting plate. The glue tank drives the baffle downward, and as the baffle moves downward, the transmission plate pushes the baffle to slide outward under the guidance of the guide groove and guide rail, so that the baffle gradually opens. When the electric lifting rod is fully extended, the baffle is fully opened and lowered to the lowest position, with the inner side of the two sets of baffles at an appropriate distance from the outer wall of the rubber roller. At this time, the top of the glue tank is horizontal with the top of the tank body, and the top of the rubber roller abuts against the bottom of the sponge pad. Heating by the electric heating plate can prevent the glue from solidifying, allowing the sponge pad to absorb the glue, and then evenly distributing the absorbed glue. The glue is applied to the outer wall of the rubber roller. The rotation of the roller ensures the glue is evenly spread onto the film. After gluing, when the equipment is not in use, the electric lifting rod is activated. This lifts the glue tank upwards via the connecting plate. The glue tank then moves the baffle upwards. As the baffle moves upwards, it slides inwards via the transmission plate, gradually closing the baffle. When the electric lifting rod is fully retracted, the baffle is completely closed, sealing the glue outlet and preventing further dripping. The glue tank can then be raised and exposed. Opening the material cover allows for easy replenishment of glue, preventing waste and improving usability. Attached Figure Description

The groove 9 and the two sets of baffles 10 are both fixed with guide rails 11 at both ends. The two sets of baffles 10 are symmetrically mounted on the glue outlet 8 through the cooperation of the guide rails 11 and the guide groove 9. The glue tank 5 is fixedly connected with a sponge pad 12 and an electric heating plate 13. The bottom end of the sponge pad 12 contacts the top end of the two sets of baffles 10. The inner walls of the box 1 are fixedly connected with two sets of fixing plates 14. The two sets of fixing plates 14 are symmetrically distributed on both sides of the rubber roller 4. The bottom of the two sets of baffles 10 is symmetrically hinged with two sets of transmission plates 15. The bottom ends of the two sets of transmission plates 15 on the left and the two sets of transmission plates 15 on the right are respectively hinged to the top ends of the two sets of fixing plates 14. The bottom end of the fixing plate 14 on the left side of the rubber roller 4 is fixedly connected with a long plate 16. The bottom of the long plate 16 is fixedly equipped with a long plate 16. There is a glue brush 17; when applying glue, the electric lifting rod 6 is activated, which pushes the glue tank 5 downward through the connecting plate 7. The glue tank 5 drives the baffle 10 downward, and when the baffle 10 moves downward, the transmission plate 15 pushes the baffle 10 to slide outward under the guidance of the guide groove 9 and the guide rail 11, so that the baffle 10 gradually opens. When the electric lifting rod 6 is fully extended, the baffle 10 is fully opened and lowered to the lowest position. The inner side of the two sets of baffles 10 is at an appropriate distance from the outer wall of the rubber roller 4. At this time, the top of the glue tank 5 is horizontal with the top of the box body 1, and the top of the rubber roller 4 is against the bottom of the sponge pad 12. The heating of the electric heating plate 13 can prevent the glue from solidifying, so that the sponge pad 12 absorbs the glue, and then the absorbed glue is evenly applied. The glue is evenly applied to the film by rotating the rubber roller 4 on its outer wall. After the glue is applied, when the equipment is not in use, the electric lifting rod 6 is started, which pulls the glue tank 5 upward through the connecting plate 7. The glue tank 5 drives the baffle 10 upward. As the baffle 10 moves upward, it slides inward through the transmission plate 15, causing the baffle 10 to gradually close. When the electric lifting rod 6 is fully retracted, the baffle 10 is completely closed, thus sealing the glue outlet 8 and preventing glue from dripping. The glue tank 5 can rise upward and be exposed outside. By opening the material cover 18, it is easy to add glue to the glue tank 5, thus avoiding glue waste and improving its practicality.

[0023] The glue tank 5 is fixedly provided with an observation window 19 at the top; by providing the observation window 19, it is easy to observe the glue status inside the glue tank 5 so that it can be added in time.

[0024] The top of the material cover 18 is fixedly provided with a handle 20; by providing the handle 20, the glue tank 5 can be opened, closed and put in more conveniently.

[0025] The front end of the housing 1 is equipped with a protective cover 21; by setting the protective cover 21, the sprockets and chains in the prior art can be covered to prevent accidental injury to personnel during operation.

[0026] Ribs 22 are fixedly connected to both ends of the glue tank 5 and the bottom ends of the two sets of connecting plates 7; by setting the ribs 22, the connection between the connecting plates 7 and the glue tank 5 can be made more firm and stable.

[0027] This utility model discloses a gluing machine for forming thermoplastic polyurethane invisible car wraps. Its working principle is as follows: During gluing, the electric lifting rod 6 is activated. The electric lifting rod 6 pushes the glue tank 5 downwards via the connecting plate 7. The glue tank 5 drives the baffle 10 downwards. As the baffle 10 moves downwards, the transmission plate 15 pushes the baffle 10 to slide outwards under the guidance of the guide groove 9 and the guide rail 11, gradually opening the baffle 10. When the electric lifting rod 6 is fully extended, the baffle 10 is fully opened and lowered to its lowest position. The inner sides of the two sets of baffles 10 are at an appropriate distance from the outer wall of the rubber roller 4. At this time, the top of the glue tank 5 is horizontal with the top of the tank body 1, and the top of the rubber roller 4 abuts against the bottom of the sponge pad 12. Heating by the electric heating plate 13 prevents the glue from solidifying, allowing the sponge pad 12 to... The adhesive is absorbed and then evenly applied to the outer wall of the rubber roller 4. The rotation of the rubber roller 4 ensures that the adhesive is evenly applied to the film. Excess adhesive on the film is scraped off by the adhesive brush 17. After the adhesive application is completed, when the equipment is not in use, the electric lifting rod 6 is started, which pulls the adhesive tank 5 upward through the connecting plate 7. The adhesive tank 5 drives the baffle 10 upward. As the baffle 10 moves upward, it slides inward through the pull of the transmission strip 15, causing the baffle 10 to gradually close. When the electric lifting rod 6 is fully retracted, the baffle 10 is completely closed, thereby sealing the glue outlet 8 and preventing the adhesive from continuing to drip. The adhesive tank 5 can then rise upward and be exposed outside. The adhesive can be easily replenished by opening the material cover 18.
