Description

Technical Field

[0001] This utility model belongs to the field of car wrap film processing technology, and in particular relates to a car wrap film forming equipment. Background Technology

[0002] In the current field of car wrap processing technology, car wrap is a film applied to the surface of a car. Car wrap is essentially a transparent protective film applied to the car's paint surface; it's also commonly called a car body transparent film or car paint protection film. Its essence is a polyurethane film, which possesses superior toughness and abrasion resistance, and is impact-resistant. After application, it isolates the car's paint surface from the air, thus providing protection against acid rain, oxidation, and scratches. Depending on the type of car wrap, it requires molding equipment for shaping and processing.

[0003] Utility model patent CN211892013U discloses a compression molding mold for preparing TPU film, belonging to the field of TPU film production equipment. It includes a base with support columns fixedly welded to both sides. Nuts are threadedly connected to the outer sides of the support columns, and a first spring is slidably sleeved on the outer side of each support column. A support seat is fixedly welded to the upper end of the support columns, and a hydraulic press is screwed and fixedly mounted on the upper end of the support seat. A connecting rod is fixedly welded to the hydraulic rod of the hydraulic press. This compression molding mold for preparing TPU film allows for easy removal and replacement of the cutting edge plate by rotating the nut counterclockwise and moving it upwards. The nut design limits the connecting plate, preventing overpressure damage to parts. The downward pressure of the connecting plate drives the positioning pin, pressure plate, and rubber layer downwards, causing the cutting edge plate to cut the TPU film, achieving integrated compression and cutting, significantly improving production efficiency. The rubber layer and the second spring design protect the parts from damage during compression.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The aforementioned patent protects the parts by setting a rubber layer and a second spring. However, during the processing of the car wrap film, the film tends to stick to the inside of the mold and is difficult to remove, which reduces the processing efficiency of the car wrap film. Utility Model Content

[0040] Please see Figure 1-4 This utility model provides a technical solution: a car wrap film forming device, including a support mechanism 1, the support mechanism 1 including a base 11, a top plate 12 mounted on the base 11 via a support frame, two hydraulic push rods 121 fixedly mounted on the lower surface of the top plate 12, a fixed mold base 2, the fixed mold base 2 including a support box 21, the support box 21 fixedly mounted on the base 11, the support box 21 having a sliding groove 211, and a fixed mold 23 slidably connected in the sliding groove 211, a movable mold base 3, the movable mold base 3 fixedly mounted on the telescopic ends of the two hydraulic push rods 121, and a conveying mechanism 4, which includes a mounting housing 41 and a guide rail 44, both of which are supported by brackets. The mounting housing 41 and guide rail 44 are symmetrically arranged along the center line of sliding groove 211 and are fixedly mounted on the support box 21. A drive screw 411 is rotatably mounted inside the mounting housing 41. A slider 413 is threadedly connected to the drive screw 411. A drive motor 412 is fixedly mounted on the outer wall of the mounting housing 41. The drive motor 412 is connected to the drive screw 411. A slider 441 is slidably connected to the guide rail 44. A mounting frame 42 is fixedly mounted on slider 413 and slider 441. A conveying roller 43 is rotatably mounted on the mounting frame 42. A reduction motor 431 is fixedly mounted on the mounting frame 42. The reduction motor 431 is connected to the conveying roller 43.

[0041] The drive motor 412 drives the drive screw 411 to rotate, which in turn drives the first slider 413 to move laterally. The second slider 441 slides on the guide rail 44, which facilitates the lateral movement of the mounting frame 42. The reduction motor 431 drives the conveying roller 43 to rotate, which conveys the formed car wrap film. The support box 21 is equipped with an inclined guide plate to facilitate the sliding out of the car wrap film and improve the processing efficiency of the car wrap film.

[0042] Multiple pneumatic push rods 231 are fixedly installed on the bottom wall of the sliding groove 211. The telescopic ends of the multiple pneumatic push rods 231 are fixedly connected to the fixed mold 23, and supports 212 are fixedly installed on both sides of the inner wall of the sliding groove 211.

[0043] In addition, the pneumatic push rod 231 drives the fixed mold 23 to move longitudinally, raising the fixed mold 23 so that the car wrap film inside the fixed mold 23 can slide out. When the pneumatic push rod 231 descends, the fixed mold 23 is supported by the support 212, which improves the stability of the fixed mold 23.

[0044] A water storage tank 24 is installed inside the support box 21. A fixing frame 22 is provided on the upper surface of the support box 21. The fixing frame 22 is arranged around the sliding groove 211, and multiple nozzles 221 are installed on the inner wall of the fixing frame 22. A water pump 241 is installed inside the support box 21. One end of the water pump 241 is connected to the water storage tank 24 through a pipe, and the other end is connected to the multiple nozzles 221 through a pipe.

[0045] Furthermore, the water tank 24 stores anti-sticking agent, and the water pump 241 draws the anti-sticking agent and delivers it to multiple nozzles 221. The multiple nozzles 221 spray the anti-sticking agent into the fixed mold 23 to prevent the car wrap film from sticking to the fixed mold 23, so as to facilitate the conveying mechanism 4 to convey the formed car wrap film.

[0046] The moving mold base 3 includes a lifting plate 31, which is fixedly connected to the telescopic ends of two hydraulic push rods 121. An upper pad 32 is provided below the lifting plate 31. A moving mold 33 is detachably installed on the lower surface of the upper pad 32. Two sliding rods 34 are fixedly installed on the upper pad 32. The sliding rods 34 are slidably connected to the lifting plate 31. A limit plate 342 is fixedly installed at the upper end of the lifting plate 31. A shock-absorbing spring 341 is fitted on the sliding rod 34. One end of the shock-absorbing spring 341 abuts against the lifting plate 31, and the other end abuts against the upper pad 32.

[0047] Specifically, when the telescopic end of the hydraulic push rod 121 extends, it drives the upper pad 32 to descend, compresses the shock-absorbing spring 341, and drives the lifting plate 31 and the moving mold 33 to descend, so that the moving mold 33 cooperates with the fixed mold 23 to form the car wrap film. The shock-absorbing spring 341 reduces the vibration of the lifting plate 31 when it descends through its own elasticity, thus extending the service life of the moving mold 33.

[0048] The working principle and usage process of this utility model are as follows: Please refer to... Figure 1-4The water pump 241 draws anti-sticking agent and delivers it to multiple nozzles 221. The multiple nozzles 221 spray the anti-sticking agent into the fixed mold 23. The drive motor 412 drives the drive screw 411 to rotate, which drives the slider 413 to move laterally, so that the conveying roller 43 moves away from the sliding groove 211. The raw material is fed into the fixed mold 23. When the extension end of the hydraulic push rod 121 extends, it drives the upper pad 32 to descend, squeezing the shock-absorbing spring 341, which drives the lifting plate 31 and the moving mold 33 to descend, so that the moving mold 33 cooperates with the fixed mold 23 to form the car wrap film. After the moving mold 33 is lifted, the pneumatic push rod 231 drives the fixed mold 23 to move longitudinally and rise from the sliding groove 211. The drive motor 412 drives the drive screw 411 to rotate, which drives the mounting frame 42 to move above the fixed mold 23. The reduction motor 431 drives the conveying roller 43 to rotate, and the conveying roller 43 conveys the formed car wrap film, so that the car wrap film slides out from the fixed mold 23.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
