[0001] This invention relates to the field of signboard lamination equipment technology, specifically to an automated signboard lamination device. Background Technology

[0002] To protect the surface of signs from daily wear and tear, ultraviolet radiation, and chemical corrosion, it is necessary to cover the surface of the signs with a coating material. Currently, most of the coating is done manually, which is inefficient and costly. Therefore, we propose an automated coating device for signs. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an automated signboard laminating device that overcomes these deficiencies. The device features a reasonable design and compact structure, solving the problems of low efficiency and high production costs associated with manual signboard lamination.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated signboard laminating device, comprising a workbench, a film feeding roller, a film receiving roller, a cutting plate, and a conveyor belt for conveying the signboard. A film roll is mounted on the film feeding roller, and the film roll includes release paper and adhesive film spaced apart on the release paper. One end of the release paper is wound around the front end of the cutting plate via a guide roller, and then connected to the film receiving roller via another guide roller. The workbench is provided with a guide rail mechanism for sliding a film pulling mechanism. The film pulling mechanism includes a film pulling motor, and a cam is connected to the output end of the film pulling motor. A connecting rod is eccentrically connected to the side of the cam away from the output end of the film pulling motor. A fixed rod is rotatably connected to the inner side of the connecting rod away from the cam. A cutting plate is connected to the end of the fixed rod. The front end of the cutting plate is thin and is positioned corresponding to the cutting plate to separate the release paper and adhesive film on the top of the cutting plate.

[0007] The cutting plate is equipped with a clamping unit for holding the film;

[0008] A pressure plate is rotatably connected to the top of the cutting plate. The pressure plate is located under the cam, and its bottom is connected to the top of the cutting plate through a support spring.

[0009] Furthermore, the guide rail mechanism is located on both sides of the film stretching mechanism to support the sliding of the film stretching mechanism;

[0010] The guide rail mechanism includes an upper guide plate and a lower guide plate. The upper guide plate is disposed on top of the lower guide plate, and the lower guide plate has a slit. The cutting plate in the film stretching mechanism slides along the slit.

[0011] Furthermore, the clamping unit includes a clamping plate that rotates on the cutting plate. One end of the clamping plate passes through the cutting plate and is connected to the bottom of the cutting plate via a connecting spring. The clamping plate is provided with a lower buckle, and the bottom of the cutting plate is rotatably connected to an upper buckle that cooperates with the lower buckle. Both ends of the upper buckle are connected to the bottom of the cutting plate via torsion springs.

[0012] Furthermore, the clamping plate has a vertical plate at one bottom and a clamping head at the other end, which is positioned above the cutting blade side.

[0013] Furthermore, the lower guide plate is provided with a ramp to cooperate with the vertical plate, the lower guide plate is provided with a support plate to support the cutting plate, and a baffle to cooperate with the upper buckle is provided on one side of the support plate.

[0014] Furthermore, the front end of the pressure plate extends downward to form a pressure head for pressing the film. The end of the pressure plate away from the pressure head is provided with a beveled surface and a flat surface in sequence. The distance from the flat surface to the rotation axis of the cam is greater than the distance from the farthest end of the cam to its axis.

[0015] Furthermore, the worktable is provided with a pressure roller and a cutting assembly. The pressure roller is positioned between the film stretching mechanism and the cutting assembly and is used to roll the film on the top of the sign. The cutting assembly is used to cut off any excess film at the front end of the top of the sign.

[0016] Furthermore, the cutting assembly includes a cutting motor, the output end of which is connected to a lead screw, a slider is threaded onto the outer wall of the lead screw, a cutter is provided at the bottom of the slider, and a guide plate is provided on the worktable for the slider to slide.

[0017] Furthermore, push plates are provided at intervals on the conveyor belt.

[0018] (III) Beneficial Effects

[0019] This invention provides an automated signboard laminating device. It offers the following advantages:

[0020] 1. The cutting plate separates the release paper and the film. The clamp, in conjunction with the cutting plate, holds the front end of the film. The pressing head presses the end of the film onto the front end of the sign. The sign moves forward, causing the film to adhere to the sign. This automated process completes the film application for the sign, improving work efficiency and reducing labor costs.

[0021] 2. When the clamping head and the cutting plate hold the front end of the film, the lower buckle is fastened to the upper buckle. As the cutting plate moves away from the cutting plate, the clamping head will not deflect, so as to ensure that the film is pulled, which will inevitably separate the film from the release paper and improve the film application quality.

[0022] 3. After the cutting plate is reset, the clamp is deflected and reset under the action of the baffle, releasing the clamping force on the film, which facilitates the subsequent movement of the sign to drive the film application and complete the film application. The entire movement process of the clamp does not require the use of a drive mechanism, which reduces the production cost and control accuracy of the entire device.

[0023] 4. The cutting component cuts off the excess film on the front of the sign. When workers clean up later, they can simply peel off the cut-off excess film from the front of the sign without any excess film affecting the overall aesthetics of the sign. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] See attached document Figure 1-20An automated signboard laminating device includes a workbench 1, on which are mounted a film feeding roller 3, a film taking-up roller 4, a cutting plate 5, and a conveyor belt 2 for conveying the signboards. The film roll is mounted on the film feeding roller 3 and includes release paper and adhesive film spaced on the release paper. One end of the release paper is wound around the front end of the cutting plate 5 via a guide roller, and then connected to the film taking-up roller 4 via another guide roller. The guide rollers are positioned vertically on both sides of the release paper and are driven to rotate by a motor to transport the release paper. Then, the film taking-up roller 4 rotates to complete the winding of the release paper on the film feeding roller 3. The movement of the release paper is not directly driven by the rotation of the film taking-up roller 4, which can avoid the gradual increase in the outer diameter of the film taking-up roller 4 affecting the length of the release paper movement and can greatly improve the accuracy of signboard lamination.

[0047] The workbench 1 is equipped with a guide rail mechanism for the film pulling mechanism to slide. The film pulling mechanism includes a film pulling motor 71. The output end of the film pulling motor 71 is connected to a cam 72. The side of the cam 72 away from the output end of the film pulling motor 71 is eccentrically connected to a connecting rod 73. The side of the connecting rod 73 away from the cam 72 is rotatably connected to a fixed rod 74. The end of the fixed rod 74 is connected to a cutting plate 75. The front end of the cutting plate 75 is thin and is set corresponding to the cutting plate 5. It is used to separate the release paper and the film on the top of the cutting plate 5. When the sign is conveyed by the conveyor belt 2 to the bottom of the cutting plate 5, the front end of the sign exceeds the front end of the cutting plate 5 and the conveyor belt 2 stops working. Then the film pulling motor 71 is started. At this time, the cam 72 rotates and drives the fixed rod 74 to move through the connecting rod 73, which further causes the cutting plate 75 to reciprocate in the guide rail mechanism. When the cutting plate 75 moves toward the cutting plate 5, the front end of the cutting plate 75 is inserted between the release paper and the film on the top of the cutting plate 5, so that the film is separated from the release paper.

[0048] The cutting plate 75 is equipped with a clamping unit for holding the film. The clamping unit then holds the film, and the cam 72 continues to rotate, causing the cutting plate 75 to move away from the cutting plate 5.

[0049] A pressure plate 77 is rotatably connected to the top of the cutting plate 75. The pressure plate 77 is located under the cam 72, and its bottom is connected to the top of the cutting plate 75 through a support spring 78. As the cutting plate 75 moves away from the cutting plate 5, the protrusion of the cam 72 presses against the top of the pressure plate 77, causing the pressure plate 77 to deflect downward. At this time, the pressure plate 77 presses the film downward, so that the film held by the clamping unit is applied to the front end of the sign. Then the conveyor belt 2 drives the sign to continue moving forward. The sign drives the film to move, so that the entire film separates from the release paper and falls onto the sign, thus completing the automated film application, improving work efficiency and reducing labor costs.

[0050] In this embodiment, the guide rail mechanism is located on both sides of the film stretching mechanism to support the sliding of the film stretching mechanism;

[0051] The guide rail mechanism includes an upper guide plate 61 and a lower guide plate 62. The upper guide plate 61 is located on top of the lower guide plate 62, and the lower guide plate 62 is provided with a slit 63. The cutting plate 75 in the film stretching mechanism slides along the slit 63. When the film stretching mechanism moves in the guide rail mechanism, the cutting plate 75 moves along the slit 63, which improves the stability of the movement.

[0052] The clamping unit includes a clamping plate 761 that rotates on the cutting plate 75. One end of the clamping plate 761 passes through the cutting plate 75 and is connected to the bottom of the cutting plate 75 via a connecting spring 762. The clamping plate 761 is provided with a lower buckle 763. The bottom of the cutting plate 75 is rotatably connected to an upper buckle 764 that cooperates with the lower buckle 763. Both ends of the upper buckle 764 are connected to the bottom of the cutting plate 75 via torsion springs 765. When the clamping unit clamps the film, the clamping plate 761 deflects. Its front end cooperates with the top of the cutting plate 75 to clamp the film, and the rear end of the lower buckle 763 deflects upward and latches onto the upper buckle 764. This ensures that when the cutting plate 75 moves away from the cutting plate 5, the clamping plate 761 will not reset under the action of the connecting spring 762, so that the clamping plate 761 can maintain the clamping force on the film.

[0053] Furthermore, the clamping plate 761 has a vertical plate 7611 at one bottom and a clamp 7612 at the other end. The clamp 7612 is positioned above the cutting edge side of the cutting plate 75. The lower guide plate 62 has a ramp 64 that cooperates with the vertical plate 7611. The lower guide plate 62 has a support plate 65 that supports the cutting plate 75. A baffle 66 that cooperates with the upper buckle 764 is provided on one side of the support plate 65. As the cutting plate 75 moves closer to the cutting plate 5, the vertical plate 7611 gradually approaches the ramp 64, and the clamp 7612 at the other end of the clamping plate 761 moves downward due to the influence of the ramp 64. The clamp 7612 can work with the top of the cutting plate 75 to clamp the film. After the cutting plate 75 moves away from the cutting plate 5, the baffle 66 will abut against the upper buckle 764, causing the upper buckle 764 to deflect. At this time, the upper buckle 764 no longer limits the lower buckle 763. Under the action of the connecting spring 762, the clamp 761 resets, causing the clamp 7612 to deflect upward and no longer clamp the film, which facilitates the subsequent movement of the sign to drive the film to complete the film application. The entire movement of the clamp does not require the use of a drive mechanism, which reduces the production cost and control accuracy of the entire device.

[0054] In this embodiment, the front end of the pressure plate 77 extends downward to form a pressure head 771 for pressing the film. After the pressure plate 77 is subjected to pressure from the cam 72, the pressure head 771 will press the film downward, so that the film is applied to the front end of the sign. The end of the pressure plate 77 away from the pressure head 771 is provided with a beveled part 772 and a flat part 773 in sequence. The distance from the flat part 773 to the rotation axis of the cam 72 is greater than the distance from the farthest end of the cam 72 to its axis, providing space for the movement of the cam 72 and preventing the cam 72 from prematurely pressing the pressure plate 77, so that the pressure plate 77 presses down on the film before the cutting plate 75 and the cutting plate 5 are separated.

[0055] In this embodiment, the workbench 1 is equipped with a pressure roller 8 and a cutting component. The pressure roller 8 is located between the film stretching mechanism and the cutting component and is used to roll the film on the top of the sign. After the sign moves with the film, it is rolled by the pressure roller 8, so that the film is completely attached to the sign. The cutting component is used to cut off the excess film at the front end of the top of the sign. The cutting component cuts the excess film attached to the front end of the sign, and the worker can then simply peel off the cut excess film attached to the front end of the sign.

[0056] In this embodiment, the cutting assembly includes a cutting motor 91, a lead screw 92 connected to the output end of the cutting motor 91, a slider 93 threadedly connected to the outer wall of the lead screw 92, a cutter 94 at the bottom of the slider 93, and a guide rail plate 95 on the worktable 1 for the slider 93 to slide. When the cutting motor 91 is started, it drives the lead screw 92 to rotate, so that the slider 93 drives the cutter 94 to move along the guide rail plate 95 and cuts off the excess film at the front end of the sign.

[0057] In this embodiment, push plates 21 are provided at intervals on the conveyor belt 2. The push plates 21 are made of rubber to increase the pushing force of the conveyor belt 2 on the sign and prevent the sign from stopping due to resistance.

[0058] Working principle: The conveyor belt 2 moves the top label to below the cutting plate 5 and then stops. At this time, the film pulling motor 71 drives the cam 72 to rotate, which in turn causes the connecting rod 73 to drive the fixed rod 74 to move. The cutting plate 75 moves along the cut 63. When the cutting plate 75 moves towards the cutting plate 5, it will insert between the release paper and the film at the top of the cutting plate 5, causing the release paper and the film to separate. During this process, the vertical plate 7611 will deflect upward under the obstruction of the ramp 64, which will further cause the clamp 76 to... 12 deflects downwards and, in conjunction with the top of the cutting plate 75, clamps the front end of the film. When the vertical plate 7611 deflects upwards, the lower latch 763 engages with the upper latch 764. Under the action of the connecting spring 762, the clamp 7612 of the clamping plate 761 maintains the pressure on the film. The cam 72 continues to rotate. Subsequently, when the cutting plate 75 moves away from the cutting plate 5, it can drive the film to move, ensuring that the film separates from the release paper and preventing the film from not separating from the release paper, thus improving the film application quality.

[0059] As cam 72 continues to rotate and cutter 75 moves away from cutting plate 5, cam 72 will press pressure plate 77, causing pressure plate 77 to deflect and press head 771 to press the end of the film onto the front end of the sign. Then, cutter 75 returns to its initial position. At this time, upper latch 764 will press against baffle 66, causing upper latch 764 to deflect. At this time, upper latch 764 no longer locks lower latch 763. Under the action of connecting spring 762, clamp 761 returns to its initial position, and clamp head 7612 deflects upward, no longer pressing the end of the film. At this time, the film pulling electric... When machine 71 stops working, conveyor belt 2 starts working and drives the sign forward. At this time, the film on the front of the sign will follow the movement of the sign and be applied to the front of the sign. Then, after being pressed by pressure roller 8, the film is completely applied to the sign. Then, the sign moves under the cutting component driven by conveyor belt 2. At this time, cutting motor 91 starts and drives lead screw 92 to rotate. Then, slider 93 drives cutter 94 to cut off the excess film on the front of the sign. The film application process of the sign is completed automatically, which improves work efficiency and reduces labor costs.
