[0018] The pressing block is provided with belt holes at the front and rear positions corresponding to the belt pressing grooves.

[0019] Optionally, a belt pressing rod is horizontally rotatably installed in the middle of the belt pressing pull frame, and belt pressing winding wheels are fixedly installed at the positions of the belt pressing grooves at both ends of the belt pressing rod, and a belt pressing winding wheel is wound with a belt pressing belt.

[0023] The present invention provides a film coating device for automobile interior decoration parts, which has the following beneficial effects:

[0024] First of all, the device realizes the automation and intelligence of interior parts lamination, greatly improving production efficiency. When the lamination lead-out frame moves toward one end of the clamping end seat by following the film frame, the extrusion block squeezes the clamping plate outward, the second spring is compressed, and the clamping block moves away from the edge of the lamination top cover frame.

The end of the interior parts film coil is squeezed between the clamping slot of the clamping block and the brim, and the interior parts film coil is covered on the upper end of the lamination top cover frame. The device can automatically complete the entire process from film material release, flattening, covering to cutting, reducing the tediousness and errors of manual operation, making the production process smoother and more efficient.

[0025] Secondly, the laminating process is accurate and stable, ensuring the improvement of product quality. The laminating guide plate, pressure belt groove, and clamping end seat in the device effectively ensure the flatness and fit of the film roll for interior parts, avoiding the generation of problems such as bubbles and wrinkles. At the same time, the use of the hot melt cutting knife achieves accurate cutting of the film material, ensuring the neatness and beauty of the laminating edge.

[0026] Furthermore, the device has strong adaptability and flexibility. The tilted design of the film frame, film lead-out frame and other components, as well as the film roller placement port, movable travel hole and other structural settings, enable the device to adapt to the film coating needs of interior parts of different sizes and shapes. In addition, the use of wet permeable membrane also provides better adsorption effect for interior parts of different materials, ensuring the stability of the coating.

[0027] In addition, the device also focuses on energy saving and environmental protection. The negative pressure environment formed by the suction pump when working not only enhances the adhesion between the interior parts and the film roll, but also reduces unnecessary material waste. At the same time, the aqueous solution contained in the wetting box can be recycled, reducing water resource consumption.

[0028] Finally, the coating device of the present invention also has high safety and reliability. All operations in the device are precisely controlled by the controller, avoiding the potential safety hazards caused by manual operation. At the same time, the device has a reasonable structural design and excellent material selection, ensuring the stability and durability of the device under long-term and high-load operation.

When the extrusion block 706 moves from one end of the clamping end seat 12 to one end of the laminating lead-out frame 7 with the laminating lead-out frame 7, the belt pressing follower pull block 1104 moves with it and is extended by the pressure rod 1105. The interior decoration film coil is flatly attached to the top coating frame 4, and the pressing belt 1106 follows the pulling out and moves above the pressing belt groove 402. When the pressure rod 1105 moves to the bending section of the guide strip hole 4011, the pressing belt 1106 is pressed into the pressing belt groove 402, and the edge of the interior decoration film coil is sealed. The limit switch 403 is squeezed and triggered by the pressure rod 1105, the interior decoration film coil is cut off, the extraction and pressing of the film is completed, the electromagnet is demagnetized, the magnetic limit block 1107 is reset and falls back, the pressing belt follower pull block 1104 is separated from the extrusion block 706, and the pressing belt follower pull block 1104 is pulled back by the pressing belt 1106 to the embedded groove of the clamping block 1203.

[0075] Embodiment 2, on the basis of embodiment 1, a wetting and permeable membrane 1301 is attached upwardly to the side wall below the brim 404 in the wetting box 13, and the wetting and permeable membrane 1301 carries the moisture from the wetting box 13 to keep it moist at all times, and the end of the interior trim film roll in a state to be squeezed is adsorbed on the side wall of the coating top frame 4 at the wetting and permeable membrane 1301 and remains fixed, which helps to improve the stability of the fixed end of the interior trim film roll.

[0076] The working principle of this embodiment:

[0077] First, the operator sets the relevant parameters through the controller 2 and starts the device. The film roller 602 on the film frame 6 rotates to release the interior trim film coil, which is smoothly sent out between the film drawing bottom roller 701 and the film drawing top roller 702. The piston rod of the film driving cylinder 501 pushes the film frame 6 and its attached film drawing frame 7 and cutting frame 8 to move horizontally along the upper end of the film top cover frame 4 toward the end of the pressing end seat 12. In this process, the interior trim film coil is gradually flattened and laid above the film top cover frame 4.

[0078] When the squeezing block 706 on the film lead-out frame 7 approaches the clamping end seat 12, the electromagnet at the bottom of the squeezing block 706 is activated, and the magnetic stopper block 1107 in the press belt follower pull block 1104 is attracted, so that the press belt follower pull block 1104 and the connected pressing rod 1105 and the press belt 1106 move with the movement of the film lead-out frame 7. The pressing rod 1105 slides in the guide bar hole 4011, gradually flattens the interior decoration film coil and presses it on the film top cover frame 4. When the pressing rod 1105 moves to the bending section of the guide bar hole 4011, the press belt 1106 is pressed into the press belt groove 402, so as to achieve the sealing of the edge of the interior decoration film coil.

[0079] At the same time, as the film lead-out frame 7 continues to move, the limit switch 403 is triggered, the piston rod of the cutting cylinder 801 is pushed out, and the built-in cutting hot melt knife 803 heats and cuts the interior trim film coil. At this time, the interior trim has been completely covered and sealed under the interior trim film coil.

[0080] During the laminating process, the moist permeable membrane 1301 in the moistening box 13 remains moistened, ensuring that the end of the interior trim film coil is firmly adsorbed on the side wall of the laminating top cover frame 4 to prevent it from shifting or falling off.

[0081] Subsequently, the piston rod of the film driving cylinder 501 retracts, driving the film frame 6, the film drawing frame 7 and the cutting frame 8 to return to the initial position. At this time, the pressing plate 1202 on the pressing end seat 12 is reset under the action of the second spring 1205, and the pressing block 1203 presses the end of the interior trim film coil tightly under the brim 404 of the film top frame 4 to achieve a stable fixation.

[0082] At the same time, the suction pump 10 starts to work, and the air in the film suction and pressure frame 3 is sucked out through the suction pipe and the suction and pressure hole 303 to form a negative pressure environment. The interior parts on the interior parts storage table 301 are therefore firmly adsorbed in the film suction and pressure frame 3, ensuring the stability and accuracy of the film coating process.

[0083] Finally, when the interior film roll is completely covered and fixed on the interior parts, the entire laminating process is completed. The device automatically stops working and waits for the next operation.
