The cutting guide rods are vertically and slidably connected to the cutting frame. When the piston rod of the cutting cylinder is pushed out, the cutting hot melt knife approaches the interior trim part film covering coil sent out between the film covering bottom roller and the film covering top roller and cuts the interior trim part film covering coil. After the limit switch is triggered by extrusion, the piston rod of the cutting cylinder is pushed out, and at the same time, the suction and pressure pump works.

[0016] Optionally, two pressing buffer rods are symmetrically and slidably mounted at the left and right ends of the pressing end seat towards the direction of the film covering top frame. A pressing plate is fixedly connected between the ends of the two pressing buffer rods on the film covering top frame.

[0017] A horizontally penetrating inner embedding rod slot is opened at the position where the pressing block is tangent to the top of the film covering top frame;

[0018] A belt hole is opened through the pressing block corresponding to the position of the pressing belt slot;

[0019] Optionally, a pressing belt pull rod is horizontally rotatably mounted in the middle of the pressing belt pull frame.

Under its own gravity, the upper end of the magnetic absorption limiting block is flush with the upper end surface of the belt pressing follower pulling block. When the extrusion block is directly above the belt pressing follower pulling block, the electromagnet in the limiting groove of the extrusion block is energized to adsorb the magnetic absorption limiting block to move upward and get stuck between the belt pressing follower pulling block and the extrusion block.

[0023] The present invention provides an automobile interior trim film covering device, which has the following beneficial effects:

[0024] First of all, the device realizes the automation and intelligence of interior trim film covering, greatly improving the production efficiency. When the film covering leading-out frame moves towards one end of the pressing end seat along with the film rack, the extrusion block extrudes the pressing plate to move outward, the second spring is compressed, the pressing clamping block moves away from the edge of the film covering top frame, and the lower end of the interior trim film coil sent out between the film covering leading-out bottom roller and the film covering leading-out top roller is distributed at the position under the brim. When the film covering leading-out frame follows the film rack to retract, the pressing clamping block resets under the action of the second spring, and the end of the interior trim film coil is squeezed between the pressing clamping groove of the pressing clamping block and the brim. The interior trim film coil covers the upper end of the film covering top frame, and the device can automatically complete the whole process from film material release, flattening, covering to cutting, reducing the tediousness and error of manual operation and making the production process smoother and more efficient.

[0025] Secondly, the film covering process is accurate and stable, ensuring the improvement of product quality. The designs of the film covering guiding plate, the belt pressing groove, the pressing end seat, etc. in the device effectively ensure the flatness and fitting degree of the interior trim film coil, avoiding the generation of problems such as air bubbles and wrinkles. At the same time, the use of the cutting hot melt knife realizes the accurate cutting of the film material, ensuring the neatness and beauty of the film covering edge.

[0026] Furthermore, the device has strong adaptability and flexibility. The inclined design of components such as the film rack and the film covering lead-out rack, as well as the settings of structures such as the film roller placement opening and the movable stroke hole, enable the device to adapt to the film covering requirements of interior trim parts of different sizes and shapes. In addition, the use of the wetting and permeating film also provides a better adsorption effect for interior trim parts of different materials, ensuring the stability of the film covering.

[0027] In addition, the device also pays attention to energy conservation and environmental protection. The negative pressure environment formed by the suction and pressure pump during operation not only enhances the adhesion between the interior trim part and the film covering coil, but also reduces unnecessary material waste. At the same time, the aqueous solution contained in the wetting tank can be recycled, reducing water resource consumption.

[0028] Finally, the film covering device of the present invention also has high safety and reliability. All operations in the device are precisely controlled by the controller, avoiding potential safety hazards that may be brought by manual operations. 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.

[0073] The pressing belt 1106 passes through the belt hole 1207 and is fixedly connected to a pressing belt follower pull block 1104. The pressing belt follower pull block 1104 is slidably embedded in the pressing block 1203. A pressing rod 1105 is fixedly connected to the lower ends between the left and right pressing belt follower pull blocks 1104. The pressing rod 1105 is clamped in the inner embedding rod slot 1206, and the left and right ends of the pressing rod 1105 slide in the corresponding guide strip holes 4011 on one side;

[0074] A vertically sliding L-shaped magnetic attraction limiting block 1107 is embedded in the tape pressing follower pulling block 1104. Under the action of its own gravity, the upper end of the magnetic attraction limiting block 1107 is flush with the upper end surface of the tape pressing follower pulling block 1104. When the extrusion block 706 is directly above the tape pressing follower pulling block 1104, the electromagnet in the limiting groove of the extrusion block 706 is energized to adsorb the magnetic attraction limiting block 1107 to move upward and get stuck between the tape pressing follower pulling block 1104 and the extrusion block 706. When the extrusion block 706 moves from one end of the pressing end seat 12 to one end of the film covering leading-out frame 7 along the film covering leading-out frame 7, the tape pressing follower pulling block 1104 moves along with it, and the interior trim film coil attached to the film covering top frame 4 is flattened through the pressing rod 1105. The tape pressing 1106 is pulled out and moves above the tape pressing groove 402. When the pressing rod 1105 moves to the bent section of the guide strip hole 4011, the tape pressing 1106 is pressed into the tape pressing groove 402, the edge of the interior trim film coil is sealed, the limit switch 403 is triggered by the extrusion of the pressing rod 1105, the interior trim film coil is cut off, the drawing and pressing of the film covering are completed, the electromagnet is demagnetized, the magnetic attraction limiting block 1107 resets and falls back, the tape pressing follower pulling block 1104 is separated from the extrusion block 706, and the tape pressing follower pulling block 1104 is pulled back to the slot of the pressing clamping block 1203 by the tape pressing 1106.

[0075] Embodiment 2, on the basis of Embodiment 1, a wetting and permeating film 1301 is attached upward along the side wall below the brim 404 in the wetting box 13. The wetting and permeating film 1301 carries the moisture in the wetting box 13 and always remains in a wet state. The end of the interior trim film coil in a state of being about to be extruded is adsorbed on the side wall of the film covering top frame 4 at the wetting and permeating film 1301 to be fixed, which helps to improve the stability of the fixation of the end of the interior trim film coil.

[0076] The working principle of this embodiment:

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

[0078] When the extrusion block 706 on the film laminating lead-out frame 7 approaches the pressing end seat 12, the electromagnet at the bottom of the extrusion block 706 is activated, attracting the magnetic limit block 1107 in the pressure belt follower pull block 1104, causing the pressure belt follower pull block 1104 and the connecting pressure rod 1105 and pressure belt 1106 to move with the movement of the film laminating lead-out frame 7. The pressure rod 1105 slides in the guide bar hole 4011, gradually flattening and pressing the interior trim film coil on the film laminating top frame 4. When the pressure rod 1105 moves to the bent section of the guide bar hole 4011, the pressure belt 1106 is pressed into the pressure belt groove 402 to achieve the sealing of the edge of the interior trim film coil.

[0079] At the same time, as the film laminating lead-out frame 7 continues to move, the limit switch 403 is triggered, cutting off the piston rod of the cylinder 801 from pushing out, and the built-in cutting hot melt knife 803 heats up 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 film laminating process, the wetting permeable membrane 1301 in the wetting box 13 remains in a wet state, ensuring that the end of the interior trim film coil is firmly adsorbed on the side wall of the film laminating top frame 4 to prevent it from shifting or falling off.

[0081] Subsequently, the piston rod of the film laminating drive cylinder 501 retracts, driving the film frame 6, the film laminating lead-out frame 7, and the cutting frame 8 back to their initial positions. At this time, the pressing plate 1202 on the pressing end seat 12 resets under the action of the second spring 1205, and the pressing block 1203 tightly presses the end of the interior trim film coil under the brim 404 of the film laminating top frame 4 to achieve stable fixation.

[0082] Meanwhile, the suction and pressure pump 10 starts to work, externally pumping the air in the film laminating suction and pressure frame 3 through the suction pipe and the suction and pressure hole 303 to form a negative pressure environment. The interior trim parts on the interior trim part storage table 301 are thus firmly adsorbed in the film laminating suction and pressure frame 3 to ensure the stability and accuracy of the film laminating process.

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