Description

Technical Field

[0001] This disclosure pertains to the field of automotive film manufacturing, specifically relating to a high-strength tear-resistant automotive film manufacturing equipment and process. Background Technology

[0002] With the continuous development of technology and the increasing number of cars owned, the demand for automotive paint protection film is also rising. Automotive films can be broadly divided into two categories: one is automotive window film, which is applied to car windows to control sunlight. Its basic performance includes safety, clarity, anti-glare, UV protection, heat insulation, scratch resistance, sufficient shelf life, and privacy protection; the other is automotive color-changing film, primarily for decorative purposes. Currently, the production process of automotive films requires dividing the film into different rolls. This paper proposes a high-strength tear-resistant automotive film manufacturing equipment and process. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a high-strength tear-resistant automotive film manufacturing equipment and process, which solves the requirement of slitting the automotive film in existing technologies.

[0004] The objective of this disclosure can be achieved through the following technical solutions:

[0005] A high-strength tear-resistant automotive film manufacturing equipment and process is characterized by comprising a base unit, a rolling unit, and a push-pull unit. The rolling unit is mounted on the base unit, and the push-pull unit is mounted on the rolling unit. In actual use, the push-pull unit pulls the roll required for rolling the automotive film into the rolling unit, the rolling unit rolls the automotive film onto the roll, and after the automotive film is rolled up, the roll is pushed out to complete the packaging of the automotive film, facilitating subsequent packaging and storage.

[0006] For rolling up automotive film, the rolling unit includes a roller, which is a hollow structure. Gear teeth are provided on the inner side of one end of the roller, which mesh with a first gear. The first gear is fixedly connected to a transmission rod, which is rotatably connected to a base unit. The transmission rod is connected to the output end of a first motor via a conveyor belt, and the first motor is mounted on the base unit.

[0007] The principle and effect of the above technical solution are as follows:

[0008] In actual use, the first motor and the second motor start. The first motor drives the transmission rod and the first gear to rotate. The first gear drives the roller to rotate. The second motor starts to make the conveyor shaft rotate, which feeds the car film from the cutter holder to the roller. Under the action of the roller, it is wound onto the roll.

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] like Figure 1-5 As shown, this device is a high-strength tear-resistant automotive film manufacturing equipment and process, including a base unit 1, a rolling unit 2, and a push-pull unit 3. The rolling unit 2 is installed on the base unit 1, and the push-pull unit 3 is installed on the rolling unit 2. In actual use, the push-pull unit 3 pulls the roll required for rolling the automotive film into the rolling unit 2. The rolling unit 2 rolls the automotive film onto the roll. After the automotive film is rolled up, the roll is pushed out, completing the packaging of the automotive film, which is convenient for subsequent packaging and storage.

[0024] For rolling up automotive film, the rolling unit 2 includes a roller 21, which is a hollow structure. Gear teeth are provided on the inner side of one end of the roller 21, which mesh with a first gear 211. The first gear 211 is fixedly connected to a transmission rod 212, which is rotatably connected to a base unit 1. The transmission rod 212 is connected to the output end of a first motor 213 via a conveyor belt. The first motor 213 is mounted on the base unit 1.

[0025] For cutting the automotive film after rolling, a blade 22 is provided. Both ends of the blade 22 are slidably connected to a blade holder 23, which is fixedly mounted on a base unit 1. A transmission shaft 231 is rotatably connected to the blade holder 23. One end of the transmission shaft 231 is connected to a second gear 232, which meshes with a third gear 233. The third gear 233 is fixedly connected to the output end of a second motor 234, which is mounted on the base unit 1. Electric cylinders 221 are connected to both ends of the blade 22. The electric cylinders 221 are connected to an electromagnetic brake 222, which is connected to a relay 223. A lever 224 is rotatably connected to the blade holder 23. A pulley 225 is provided at the lower end of the lever 224, and the upper end is mounted on the relay 223. A spring connects the lever 224 and the blade holder 23. The upper end of the lever 224 is provided with a contact. When the contact on the lever 224 contacts the relay 223, the relay 223 is activated.

[0026] In actual use, the first motor 213 and the second motor 234 start. The first motor 213 drives the transmission rod 212 and the first gear 211 to rotate. The first gear 211 drives the roller 21 to rotate. The second motor 234 starts, causing the conveyor shaft 231 to rotate, feeding the car film from the cutter holder 23 to the roller 21. Under the action of the roller 21, the film is wound onto the drum. The pulley 225 on the lever 224 is in contact with the surface of the drum and the car film. As the thickness of the car film increases, the lever 224 rotates. When the car film is rolled to a certain thickness, the contact point on the lever 224 contacts the relay 223. The relay 223 controls the electromagnetic brake 222 to start. The electromagnetic brake 222 controls the electric cylinder 221 to start. Under the action of the electric cylinder 221, the blade 22 falls to cut the car film.

[0027] For placing the film roll onto the roller 21 before winding and removing the roll after winding, a push-pull unit 3 is provided, including a push-pull rod 31. The push-pull rod 31 is set in a push-pull groove opened in the roller 21. One end of the push-pull rod 31 is set outside the roller 21, and the other end is set inside the roller 21. The end of the push-pull rod 31 inside the roller 21 is connected to a moving plate 32. A threaded rod 321 and a sliding rod 322 pass through the moving plate 32. The two ends of the sliding rod 322 are fixedly connected to a fixed plate 33. The two ends of the threaded rod 321 are rotatably connected to the fixed plate 33. One end of the threaded rod 321 passes through the fixed plate 33 and is fixedly connected to the output shaft of a third motor 331. The third motor 331 is mounted on the fixed plate 33, and the fixed plate 33 is fixedly installed inside the roller 21.

[0028] The push-pull rod 31 extends out of the roller 21 and is hinged to a gripper 311. A fourth gear 312 is provided on the rotating shaft of the gripper 311. The fourth gear 312 meshes with a rack 313. The rack 313 is slidably connected to the push-pull rod 31. A fifth gear 314 meshes with the end of the rack 313 away from the fourth gear 312. The fifth gear 314 is rotatably connected to the push-pull rod 31. The fifth gear 314 meshes with the sixth gear 315. The sixth gear 315 is fixedly connected to the first helical gear 316. The first helical gear 316 meshes with the second helical gear 317. The second helical gear 317 is fixedly connected to the seventh gear 318. The sixth gear 315, the first helical gear 316, the second helical gear 317, and the seventh gear 318 are all rotatably connected to the moving plate 32. The seventh gear 318 meshes with the rotating gear ring 34. The rotating gear ring 34 is slidably connected to the fixed plate 33. An eighth gear 341 meshes with the rotating gear ring 34. The eighth gear 341 is fixedly connected to the output end of the fourth motor 342. The fourth motor 342 is mounted on the fixed plate 33.

[0029] In actual use, the third motor 331 starts, the threaded rod 321 rotates, moving the moving plate 32 and the push-pull rod 31 to the outermost end of the drum 21. The worker places the drum on the drum 21. At this time, the fourth motor 342 starts, driving the rotating gear ring 34 to rotate. The rotating gear ring 34 drives the seventh gear 318 to rotate, which in turn drives the second helical gear 317, the first helical gear 316, and the sixth gear 315 to rotate. The sixth gear 315 drives the fifth gear 314 to rotate, which in turn moves the rack 313. The rack 313 then drives the fourth gear 312 to rotate, which in turn drives the gripper rod 311 to rotate. The gripper rod 311 rotates 90° and grips the drum. The third motor 331 reverses, pulling the drum onto the drum 21. The fourth motor 342 reverses again, the gripper rod 311 straightens, and winding begins. After winding is complete, the third motor 331 starts, and the push-pull rod 31 pushes the drum out of the drum 21.

[0030] For assisting in the rolling of automotive film, the base unit 1 includes a mounting base 11, on which the rolling unit 2 is mounted. Two stabilizing cylinders 12 are mounted on the mounting base 11, positioned behind the blade holder 23. The stabilizing cylinders 12 are rotatably connected to the mounting base 11. A rotating shaft passes through the mounting base 11 at one end of each stabilizing cylinder 12, and gear teeth are mounted on the rotating shaft. The rotating shaft of one of the two stabilizing cylinders 12 meshes with a ninth gear 121, which is fixedly connected to the output end of a fifth motor 122. The ninth gear 121 meshes with a tenth gear 123, which in turn meshes with the rotating shaft of the other stabilizing cylinder 12.

[0031] In actual use, the fifth motor 122 starts, driving the ninth gear 121 and the tenth gear 123 to rotate, causing the two stabilizing cylinders 12 to rotate. The automotive film that has completed the previous production step enters the stabilizing cylinder 12, and then enters the cutter holder 23 for subsequent steps. This prevents wrinkles from forming before the automotive film is rolled up and prevents deviation during operation.

[0032] In actual use, the third motor 331 starts, the threaded rod 321 rotates, moving the moving plate 32 and the push-pull rod 31 to the outermost end of the drum 21. The worker places the drum on the drum 21. At this time, the fourth motor 342 starts, driving the rotating gear ring 34 to rotate. The rotating gear ring 34 drives the seventh gear 318 to rotate, which in turn drives the second helical gear 317, the first helical gear 316, and the sixth gear 315 to rotate. The sixth gear 315 drives the fifth gear 314 to rotate, which in turn moves the rack 313. The rack 313 then drives the fourth gear 312 to rotate, which in turn drives the gripper rod 311 to rotate. The gripper rod 311 rotates 90° and grips the drum. The third motor 331 reverses, pulling the drum onto the drum 21. The fourth motor 342 reverses, the gripper rod 311 straightens, and winding begins. The fifth motor 122 starts, driving the ninth gear 121 and the tenth gear 123 to rotate, causing the two stabilizing cylinders 12 to rotate. The automotive film that has completed the previous production step enters the stabilizing cylinder 12 and then enters the cutter holder 23. The first motor 213 and the second motor 234 start, driving the transmission rod 212 and the first gear 211 to rotate. The first gear 211 drives the roller 21 to rotate. The second motor 234 starts, causing the conveyor shaft 231 to rotate, sending the automotive film from the cutter holder 23 to the roller 21. Under the action of the roller 21, it is wound onto the roll. The pulley 225 on the lever 224 is in contact with the surface of the roll and the film. As the film thickness increases, the lever 224 rotates. When the film is rolled to a certain thickness, the contact point on the lever 224 contacts the relay 223. The relay 223 controls the electromagnetic brake 222 to start, which in turn controls the electric cylinder 221 to start. Under the action of the electric cylinder 221, the blade 22 falls to cut the film. After rolling is complete, the third motor 331 starts, and the push-pull rod 31 pushes the roll out of the roller 21.
