Description

Technical Field

[0001] The utility model relates to the technical field of film coating, and more specifically, particularly to an automatic deviation-correcting coating machine. Background Art

[0002] The coating machine is a machine that uses various forming pressure wheels to simulate manual veneer movements, applies glue to the surface of the substrate, and then attaches the decorative film material to the surface of the substrate to replace the traditional painting process. It is widely used in the coating of materials such as aluminum alloy, density board, plastic steel profiles and wood-plastic integrated wall panels. The film materials used in the coating machine are diverse, including roll films made of standard PVC film, CPL, aluminum foil, veneer and other materials. Due to the uneven tension on the film surface during the film roll feeding process, as the coating time and length increase, it will cause the film material and the substrate to be misaligned. Existing coating machines generally use manual correction, which is not only troublesome to adjust, but also has low adjustment accuracy. It will not only cause the pattern on the board to shift, but also cause some parts of the substrate to be incompletely coated, affecting the quality of the product. Utility Model Content

[0029] The feeding conveying mechanism 2, the laminating mechanism 5 and the discharging conveying mechanism 6 are sequentially arranged on the machine base 1;

[0030] The centering mechanism 3 is provided on the feeding and conveying mechanism 2 and is used to center the substrate;

[0032] In an embodiment of the utility model, the feed conveying mechanism 2 is used to convey the substrate, and the substrate is pushed to the middle position when passing through the centering mechanism 3 for better positioning and film pasting. The film feeding mechanism 4 is installed above the laminating mechanism 5, which is composed of multiple functional modules, among which the tensioning module 43 is used to pre-tension the film material conveyed, reduce the displacement of the film material and facilitate the subsequent lamination with the substrate. The monitoring module 44 is used to monitor the passing film material to determine whether the operating state of the film material is normal. When the moving position of the film material is offset, the deviation correction module 45 is started and the moving direction of the film material is corrected so that the film material returns to the correct position to improve the accuracy of the film pasting. After the film material comes out of the film feeding mechanism 4, it contacts the substrate, and is pasted on the surface of the substrate as the substrate is pushed forward, and then enters the laminating mechanism 5 for pressing. The pasted plate is sent out from the laminating mechanism 5 and transported to the outside by the discharge conveying mechanism 6.

[0033] Preferably, the correction module 45 includes a correction seat 451, a correction frame 452, a correction roller 453 and a correction cylinder 454; the correction seat 451 is connected to the fixed bracket 41, and a slide groove is provided on the inner side thereof; the correction frame 452 is provided with a roller, and is movably arranged on the slide groove through the roller; the number of the correction cylinders 454 is two, and the two correction cylinders 454 are respectively arranged on the top of the correction seat 451; the piston rod of the correction cylinder 454 is connected to the correction frame 452; the correction roller 453 is rotatably arranged in the correction frame 452.

When the film material deviates to one side, the two deflection correction cylinders 454 can be controlled to make the deflection correction frame 452 deflect in the opposite direction, so as to achieve the effect of controlling the conveying direction of the film material and then guiding the film material to the correct direction.

[0035] The roller may be a universal wheel, or the roller may be rotatably connected to the deviation correction frame 452 via a shaft.

[0036] Preferably, a guide groove or anti-skid texture is provided on the surface of the deflection-correcting roller 453.

[0038] Preferably, an adjustment component is also provided in the cover plate, and the adjustment component includes a left-hand screw rod, a left-hand nut seat, a right-hand nut seat and an adjustment handwheel; the left-hand screw rod is rotatably mounted on the cover plate, the adjustment handwheel is connected to the left-hand screw rod, the left-hand nut seat and the right-hand nut seat are respectively mounted on the left-hand screw rod, and the number of the deviation correction sensors is two, which are respectively arranged on the left-hand nut seat and the right-hand nut seat.

[0039] Through the above structural design, the left-hand screw can be driven to rotate by the adjusting hand wheel, so that the left-hand nut seat and the right-hand nut seat can move forward and backward on the left-hand screw to match the film materials of different widths. Specifically, the two screw parts in the left-hand screw are designed with positive and negative screw threads, so that the left-hand nut seat and the right-hand nut seat can be moved closer to each other or away from each other during the rotation process. In this way, only the rotation direction of the adjusting hand wheel needs to be controlled to quickly control the positions of the two nut seats for film materials of different specifications, so that the two deviation correction sensors can accurately and flexibly monitor film materials of different specifications.

[0040] Preferably, the cover plate is also provided with a digital position display, and the digital position display is connected to the left and right screw rods. By providing a digital position display and connecting the digital position display to the left and right screw rods, the amount of the left and right screw rods screwed in can be intuitively read, thereby improving the control accuracy of the adjustment hand wheel.

By providing the guide slope 32, the substrate can enter the centering baffle more easily.

[0043] Furthermore, a pulley block may be provided on the inner wall of the centering baffle to contact the substrate through the pulley block, so that the substrate can slide forward more easily and reduce the forward resistance.

[0044] Preferably, the centering baffle is installed on the feed conveying mechanism 2 through a centering seat; the centering seat includes a connecting plate, a push rod, a sliding seat, a push plate and a centering cylinder; the push rod is slidably arranged on the sliding seat, the connecting plate and the push plate are respectively arranged at both ends of the push rod, the connecting plate is connected to the centering baffle, and the push plate is connected to the piston rod of the centering cylinder. Through the above structural design, when the centering cylinder is working, it can act on the push plate and then drive the connecting plate forward and backward through the push rod, so that the position of the centering baffle can be quickly adjusted to adapt to the centering requirements of substrates of different specifications, with strong flexibility.

[0045] Preferably, an alarm device is also included, and the alarm device is connected to the monitoring module 44; a remote communication module is arranged in the alarm device. In this embodiment, when the monitoring module 44 detects that the position of the film material has a large deviation, and the deviation correction module 45 cannot effectively correct its position, the alarm device sends an alarm signal to the outside according to the working state of the monitoring module 44 to remind the maintenance personnel to carry out maintenance. Furthermore, the alarm device in this embodiment has a built-in remote communication module, and even if the maintenance personnel are not on site, the remote communication module can be used to promptly remind the maintenance personnel to quickly arrive at the site for processing.
