Description

Technical Field

[0001] The utility model relates to the technical field of automobile film production equipment, and particularly relates to an automatic edge film unrolling device for an automobile film production line. Background Art

[0002] Automobile film is a high-performance new environmentally friendly film, which is widely used in the automobile beauty and maintenance industry. The automobile film is mainly TPU film, and its production process is a film made by special processes such as calendering, casting, blown film, and coating on the basis of TPU granule material. At present, after extruding the TPU base film, it is necessary to use a film laminating machine to laminate protective films on both sides of the TPU base film.

[0003] At present, the edge film unrolling device of the protective film has the following disadvantages:

[0004] 1. It can only place one roll of coil material. Since the quantity of each roll of coil material is limited, when the coil material is used up, it is necessary to stop the machine to replace the coil material. And long-time shutdown not only causes great loss, but also needs to re-adjust the machine before it can meet the requirements of on-line production of automobile film.

[0005] 2. Ordinary unrolling devices generally use the method of turning over the roll to load the roll. Since the volume and quality of the protective film coil are large, it is easy to fall off during the turning-over process, and the safety is relatively low.

[0006] 3. During the unrolling process, the unrolling roller is prone to jitter, thus affecting the quality of the automobile film.

[0007] 4. Since the automobile film is produced on-line, it is necessary to adjust the unrolling position of the protective film at any time according to the extrusion position of the TPU film. Due to the large weight of the unrolling device plus the coil material, it is difficult for the entire unrolling device to follow the movement.

[0008] Therefore, how to design an automatic edge film unrolling device that can replace the coil material without stopping the machine, has high safety, does not jitter during the unrolling process, and can adjust the unrolling position following the production line has become an urgent technical problem in this field. Content of the Utility Model

[0009] The purpose of the utility model is to solve the deficiencies of the prior art and provide an automatic edge film unrolling device for an automobile film production line that can replace the coil material without stopping the machine, has high safety, does not jitter during the unrolling process, and can adjust the unrolling position following the production line.

Detailed Description of the Embodiment

[0033] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The present utility model can be implemented in the following manner:

[0034] Referring to Figures 1-4 , an automatic edge film unwinding device for an automobile film production line, comprising a base 1, two unwinding rollers 2 and two unwinding drivers 3, and each unwinding roller 2 corresponds to an unwinding driver 3.

[0035] Among them, a frame 4 that can reciprocate along the base 1 is arranged above the base 1; slide rails 11 are arranged at the four corners of the base 1, and sliders 41 adapted to the slide rails 11 are arranged at the bottom of the frame 4; the circuits on the base 1 and the frame 4 are installed by a drag chain 5. Installation fixing blocks 12 for fixedly installing the entire base 1 on the ground are arranged on both sides of the base 1. A plurality of mounting holes 13 for screws to pass through are arranged on the installation fixing blocks 12. A controller 6 for controlling the reciprocating movement of the frame 4 along the slide rail 11 is arranged on the side of the frame 4. When the controller 6 controls the frame 4 to move along the slide rail 11, the frame 4 drives the two unwinding rollers 2 to move synchronously, so that the unwinding roller 2 can adjust the unwinding position of the protective film at any time according to the extrusion position of the TPU film, so as to meet the requirements of on-line production of automobile film.

[0036] The two unwinding rollers 2 are arranged vertically. The two ends of the unwinding roller 2 are detachably installed on one side of the frame 4 through an anti-vibration fixing component 7; the anti-vibration fixing component 7 includes a support member 71 arranged on the frame 4. The support member 71 is in a C shape, and an upper fixing rod 711 and a lower support rod 712 protrude outward from the support member 71. A C-shaped opening 713 for the end of the unwinding roller 2 to enter and exit is formed between the upper fixing rod 711 and the lower support rod 712. An anti-vibration limiting member 72 for preventing the unwinding roller 2 from shaking during operation is arranged on the upper fixing rod 711. The anti-vibration limiting member 72 includes a locking rod 721 penetrating through the upper fixing rod 711 and a cylinder 722 for driving the locking rod 721 to move up and down. After the two ends of the unwinding roller 2 enter the C-shaped opening 713 of the support member 71, the cylinder 722 will control the locking rod 721 to move downward to lock the end of the unwinding roller 2, thereby preventing the unwinding roller 2 from displacing or shaking during the unwinding process, and effectively ensuring the production quality of the automobile film. A limiting block 714 for preventing the unwinding roller 2 from falling is protruded upward from the free end of the lower support rod 712. When it is necessary to take out the unwinding roller 2 for replacement, the unwinding roller 2 needs to be pushed away from the C-shaped opening 713. When the unwinding roller 2 moves to the limiting block 714, it can no longer move forward, thereby ensuring that the unwinding roller 2 will not come out of the lower support rod 712, and improving the safety of the automatic edge film unwinding device.

[0037] In order to rotate the unwinding roller 2 for unwinding, the two unwinding drivers 3 are connected to the anti-vibration fixing components 7 on the same side of the frame 4. At one end of the unwinding driver 3 facing the unwinding roller 2, there is a rotating connection sleeve 31 connected to one end of the unwinding roller 2. Inside the rotating connection sleeve 31, there is a rotating shaft connecting member 32. One end of the rotating shaft connecting member 32 is connected to the unwinding driver 3, and the other end is clamped with the unwinding roller 2. At one end of the unwinding roller 2 facing the rotating shaft connecting member 32, there protrudes outward a clamping convex portion 21 that is clamped with the rotating shaft connecting member 32. At one end of the rotating shaft connecting member 32 facing the unwinding roller 2, there is a concave clamping portion 321 adapted to the connecting convex portion. During the process of loading the roll, it is necessary to align the clamping convex portion 21 of the unwinding roller 2 with the clamping concave portion 321 of the rotating shaft connecting member 32 and then push it inward, so that the rotating shaft connecting member 32 can be accurately clamped with the unwinding roller 2, ensuring that the unwinding driver 3 can drive the unwinding roller 2 to rotate and unwind.

[0038] On the inner side of the support member 71, there is a coil exhaustion alarm 8, which is used to sense the thickness of the coil. In this embodiment, when the coil remains 100 m, the coil exhaustion alarm 8 will make a sound to prompt the staff to prepare for the roll change operation.

[0039] Working principle: The coil is sleeved on the two unwinding rollers 2. The forklift forks the two ends of the unwinding roller 2, and then places the unwinding roller 2 on the lower support rod 712 of the support member 71 of the anti-vibration fixing component 7. Then, the clamping convex portion 21 of the unwinding roller 2 is aligned with the clamping concave portion 321 of the rotating shaft connecting member 32 and pushed inward. When the rotating shaft connecting member 32 is accurately clamped with the unwinding roller 2, the air cylinder 722 will control the locking rod 721 to move downward to lock the end of the unwinding roller 2. After the two unwinding rollers 2 are loaded, the controller 6 is used to control the frame 4 to move along the slide rail 11, so that the unwinding position of the unwinding roller 2 is adapted to the extrusion position of the TPU film. When the coil of one of the unwinding rollers 2 is in use, the other unwinding roller 2 is in a standby state; when the coil exhaustion alarm 8 gives an alarm, a layer of double-sided tape is pasted at the unwinding end of the standby coil, and the double-sided tape of the standby coil is pasted at the end of the coil being used to achieve seamless docking of the coils. When removing the unwinding roller 2 with exhausted coil, the air cylinder 722 will control the locking rod 721 to move upward to release the end of the unwinding roller 2. The operator can push the unwinding roller 2 outward horizontally, and then use the forklift to remove the unwinding roller 2 from the support member 71.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
