Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, specifically a continuous automatic film applicator. Background Technology

[0002] The automatic laminating machine is a device that uses a belt conveyor to continuously transport products and, together with laminating components and other structures, completes the automated lamination of product surfaces. Its continuous operation mode can improve lamination efficiency and is widely used in various product surface film lamination scenarios.

[0003] Existing automated film applicators have certain drawbacks in use: during the application process, air can easily be introduced between the film layer and the product surface, resulting in air bubbles after application, which affects the product's appearance and the quality of the film application. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a continuous automatic film applicator to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous automatic film applicator, comprising a frame and a belt conveyor, wherein a mounting frame is connected to the top of the outer shell of the belt conveyor; and a support frame is connected to the upper part of the inner side of the mounting frame, wherein a lead screw passes through the top of the support frame, and an adjusting plate is connected to the outside of the lead screw; the bottom of the adjusting plate is connected to the support plate through a spring telescopic rod, and a scraper is connected to one side of the support plate; a photoelectric switch is installed at the lower part of the inner side of the mounting frame; servo electric cylinders are installed on both sides of the outer surface and both sides of the back of the mounting frame, and the output ends of the four servo electric cylinders are connected to two servo slides, and the output ends of the two servo slides are connected to push plates.

[0006] By adopting the above technical solution, continuous product conveying can be achieved through a belt conveyor. The mounting frame provides a mounting base for each component. The support frame, lead screw, adjusting plate and spring telescopic rod work together to adjust the pressure of the scraper on the product. The support plate and scraper work together to adapt to products of different heights and reduce film bubbles. The photoelectric switch, servo cylinder, servo slide and push plate work together to reduce the phenomenon of product jamming when passing through the scraper. All components work together to achieve a continuous automatic film application operation.

[0007] Furthermore, the adjusting plate is threadedly connected to the lead screw, and the adjusting plate is slidably connected to the support frame.

[0008] By adopting the above technical solution, when the lead screw is rotated, the adjusting plate can slide stably along the support frame, thereby driving the spring telescopic rod to extend and retract, realizing the adjustment of the spring preload, and providing a structural basis for flexibly adjusting the scraper pressure.

[0009] Furthermore, the support plate is rotatably connected to the mounting frame, and both ends of the spring telescopic rod are rotatably connected to the adjusting plate and the support plate, respectively.

[0010] By adopting the above technical solution, when the product lifts the scraper, the support plate can rotate around the mounting frame to accommodate products of more height specifications. At the same time, the spring telescopic rod can deform with the rotation of the support plate to ensure stable pressure is applied to the scraper and to ensure the adhesion effect between the scraper and the product film layer.

[0011] Furthermore, the bottom of the support plate abuts against the support frame.

[0012] By adopting the above technical solution, the downward rotation angle of the support plate and scraper can be limited, reducing unnecessary friction between the two and the belt conveyor caused by excessive rotation, which helps to extend the service life of the scraper and the belt conveyor.

[0013] Furthermore, the bottom of the scraper is arc-shaped.

[0014] By adopting the above technical solution, the bottom of the scraper can fit more closely to the film layer on the top of the product, and can more smoothly comb the film layer when in contact with the product, which helps to reduce air residue between the film layer and the product surface.

[0015] Furthermore, the push plate has an "n" shaped cross-section.

[0016] By adopting the above technical solution, the travel distance of the servo slide can be compensated, avoiding gaps between the push plate and the product caused by the slide travel limitation, which helps to push the product through the bottom of the scraper more smoothly.

[0017] Furthermore, a controller and a belt conveyor are respectively installed on the top of the frame, and a guide assembly and a film application assembly are respectively provided on the top of the belt conveyor.

[0018] By adopting the above technical solutions, the controller provides the control basis for equipment operation, the belt conveyor realizes the continuous conveying of products, the guide component can limit the products to ensure the stability of the conveying direction, and the film application component completes the initial film application operation on the product surface.

[0019] Furthermore, the belt conveyor, film application assembly, through-beam photoelectric switch, servo cylinder, and servo slide are all electrically connected to the controller.

[0020] By adopting the above technical solutions, the controller can uniformly regulate the operating status of each component, ensuring coordinated operation of belt conveying, film application, detection, and pushing processes, thereby improving the automation level and stability of equipment operation.

[0021] Furthermore, the scraper is made of POM or PEEK material.

[0022] By adopting the above technical solution, the high strength and low surface friction coefficient of this material can be utilized to reduce wear when the scraper contacts the product film layer, while also helping to improve the adhesion between the scraper and the film layer.

[0023] Furthermore, the scraper is detachably connected to the support frame via bolts.

[0024] By adopting the above technical solution, the scraper can be easily replaced by removing the bolts when it is damaged, ensuring the long-term stable operation of the equipment.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the arrangement of a support frame, spring telescopic rod, support plate, and scraper, allows the support frame to abut against the bottom of the support plate when the product has not yet arrived. This reduces unnecessary friction between the support plate and scraper and the conveyor belt caused by excessive downward rotation, thus extending the service life of the scraper. When the product is transported by the belt conveyor to the area below the scraper, the product can lift the scraper, and the support plate rotates within the mounting frame, thus accommodating products of greater height. Simultaneously, the spring in the spring telescopic rod applies pressure to the scraper, which, combined with the arc-shaped structure at the bottom of the scraper, helps the scraper to better adhere to the film layer on top of the product, reducing air residue between the film layer and the product surface.

[0027] 2. This utility model, through the setting of lead screw and adjustment plate, can drive the adjustment plate to move up and down by rotating the lead screw, thereby causing the spring telescopic rod to extend and retract, thereby adjusting the preload of the spring, thus flexibly adjusting the pressure applied by the scraper to the product, which helps to adapt to the film application needs of more product specifications and improve the stability of the film application effect;

[0028] 3. This utility model, through the arrangement of a photoelectric switch, a servo cylinder, a servo slide, and a pusher, allows the photoelectric switch to detect that the product is below the scraper. At this time, the servo cylinder drives the servo slide and pusher to move downwards, aligning the pusher with the product. Subsequently, the servo slide drives the pusher to move towards the product. The pusher, with its n-shaped cross-section, can compensate for the distance, helping to push the product smoothly through the bottom of the scraper and reducing material jamming caused by scraper resistance. After the product passes, the servo cylinder drives the pusher to move upwards, and the servo slide drives the pusher to reset in the opposite direction, reducing interference with the subsequent product conveying and ensuring the continuity of the assembly line operation.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A type of automated film applicator, such as Figures 1-5As shown, the system includes a frame 1 and a belt conveyor 3. A mounting frame 6 is connected to the top of the outer casing of the belt conveyor 3. A support frame 7 is connected to the upper part of the mounting frame 6. The bottom of a support plate 11 abuts against the support frame 7 to reduce unnecessary friction between the support plate 11 and the scraper 12 and the belt conveyor 3 due to excessive downward rotation. A lead screw 8 passes through the top of the support frame 7. An adjusting plate 9 is connected to the outside of the lead screw 8. The adjusting plate 9 is threadedly connected to the lead screw 8 and slidably connected to the support frame 7. If it is necessary to adjust the pressure of the scraper 12 according to product specifications, or if the spring pressure decreases after prolonged use, the operator can achieve this by rotating the lead screw 8 at the top of the support frame 7. The adjusting plate 9 is threadedly connected. Rotating the screw 8 drives the adjusting plate 9 to slide up and down along the support frame 7, thereby causing the spring telescopic rod 10 to extend and retract, thus adjusting the spring preload and enabling flexible adjustment of the scraper 12's pressure on the product, improving the film application stability of more product specifications. A support plate 11 is connected to the bottom of the adjusting plate 9 via the spring telescopic rod 10. The support plate 11 is rotatably connected to the mounting frame 6. Both ends of the spring telescopic rod 10 are rotatably connected to the adjusting plate 9 and the support plate 11, respectively. A scraper 12 is connected to one side of the support plate 11. The bottom of the scraper 12 is arc-shaped. When the product passes under the scraper 12, it first lifts the scraper 12, and the scraper 12 then drives the support plate 11 to extend and retract. The mounting bracket 6 rotates internally to accommodate products of varying heights. Subsequently, the spring telescopic rod 10 between the adjusting plate 9 and the support plate 11 deforms due to the rotation of the support plate 11. The elastic force of the spring applies pressure to the scraper 12, causing the bottom of the scraper 12 to adhere to the film layer on top of the product. Combined with the arc-shaped structure at the bottom of the scraper 12, this allows for better adhesion between the scraper 12 and the film layer on top of the product, helping to reduce air residue between the film layer and the product surface, achieving a better bubble removal effect. A photoelectric switch 13 is installed inside the lower part of the mounting bracket 6. Servo electric cylinders 14 are installed on both sides of the outer surface and the back of the mounting bracket 6. The four servo electric cylinders 14 output... Two servo slides 15 are connected to the end, and push plates 16 are connected to the output ends of the two servo slides 15. The push plates 16 have an "n" shaped cross-section. When the photoelectric switch 13 detects that the product is below the scraper 12, the controller 2 will control the servo cylinder 14 to start. The output end of the servo cylinder 14 drives the servo slides 15 to move down, so that the push plates 16 connected to the output end of the servo slides 15 correspond to the height position of the product. Then the servo slides 15 start and drive the push plates 16 to move towards the product. Since the push plates 16 have an "n" shaped cross-section, they can compensate for the distance and push the product through the bottom of the scraper 12 more smoothly, reducing the jamming phenomenon caused by the resistance of the scraper 12.

[0039] See Figure 1In the above embodiment, a controller 2 and a belt conveyor 3 are respectively installed on the top of the frame 1. A guide component 4 and a film application component 5 are respectively installed on the top of the belt conveyor 3. After the belt conveyor 3 on the top of the frame 1 is started, the operator can place the product from the left side of the belt conveyor 3. Then, the product to be filmed is conveyed to the right by the belt conveyor 3. During the conveying process, the guide component 4 limits and guides the product to ensure that the product conveying direction is stable and can be aligned with the film application component 5. Subsequently, the film application component 5 performs film application on the surface of the product. The belt conveyor 3, the film application component 5, the photoelectric switch 13, the servo cylinder 14, and the servo slide 15 are all electrically connected to the controller 2. The operator turns on the equipment through the controller 2 and uniformly controls the operation status of the belt conveyor 3, the film application component 5, and the subsequent components to ensure that all links work together.

[0040] Example 2:

[0041] Based on the above embodiment 1, in order to reduce the wear caused by the scraper 12 on the product and the film layer, the following settings are now adopted.

[0042] See Figures 2-4 In the above embodiments, the scraper 12 is made of POM or PEEK material. These materials have high strength and low surface friction coefficient, which helps to reduce wear when the scraper 12 contacts the product film layer and further improves the adhesion effect between the scraper 12 and the film layer. The procurement cost of POM is lower than that of PEEK, but the mechanical strength of POM is also lower than that of PEEK.

[0043] Example 3:

[0044] Based on the above embodiment 1, the following settings are made to facilitate the replacement of the damaged scraper 12.

[0045] See Figures 2-4 In the above embodiment, the scraper 12 is detachably connected to the support frame 7 by bolts. When the scraper 12 is damaged, the staff can easily remove the bolts to replace the scraper 12, ensuring the continuous and stable operation of the equipment.

[0046] The implementation principle of this utility model is as follows: First, the staff turns on the equipment through the controller 2 and uniformly controls the operation status of the belt conveyor 3, the film application component 5 and subsequent components to ensure that each link works in tandem. After the belt conveyor 3 at the top of the frame 1 is started, the staff can place the product from the left side of the belt conveyor 3. Then, the product to be filmed is transported to the right through the belt conveyor 3. During the transport process, the guide component 4 limits and guides the product to ensure that the product transport direction is stable and can be aligned with the film application component 5. Subsequently, the film application component 5 performs the film application operation on the surface of the product.

[0047] Before the product is conveyed by the belt conveyor 3 to the bottom of the mounting frame 6, the support frame 7 inside the mounting frame 6 supports the support plate 11, so that the bottom of the support plate 11 abuts against the support frame 7, reducing unnecessary friction between the support plate 11 and the scraper 12 and the belt conveyor 3 due to excessive downward rotation.

[0048] As the product continues to be conveyed, it will enter the mounting frame 6. When the photoelectric switch 13 detects that the product is below the scraper 12, the controller 2 will control the servo cylinder 14 to start. The output of the servo cylinder 14 drives the servo slide 15 to move down, so that the push plate 16 connected to the output of the servo slide 15 corresponds to the height position of the product. Then the servo slide 15 starts and drives the push plate 16 to move towards the product. Since the cross section of the push plate 16 is n-shaped, it can compensate for the distance and push the product through the bottom of the scraper 12 more smoothly, reducing the jamming phenomenon caused by the resistance of the scraper 12.

[0049] When the product passes under the scraper 12, it will first lift the scraper 12. The scraper 12 will drive the support plate 11 to rotate within the mounting frame 6 to accommodate products of greater height. Subsequently, the spring telescopic rod 10 between the adjusting plate 9 and the support plate 11 will deform due to the rotation of the support plate 11. The elastic force of the spring will apply pressure to the scraper 12, so that the bottom of the scraper 12 adheres to the film layer on the top of the product. Combined with the arc-shaped structure at the bottom of the scraper 12, the scraper 12 can better adhere to the film layer on the top of the product, which helps to reduce the air residue between the film layer and the product surface and achieve a better bubble removal effect.

[0050] In addition, the scraper 12 is made of POM or PEEK material. These materials have high strength and low surface friction coefficient, which helps to reduce wear when the scraper 12 comes into contact with the product film layer and can further improve the adhesion effect between the scraper 12 and the film layer. The procurement cost of POM is lower than that of PEEK, but the mechanical strength of POM is also lower than that of PEEK.

[0051] After the product passes the scraper 12, the servo slide 15 reaches its end point of travel. Its built-in limit switch to prevent overtravel will be triggered, and the servo cylinder 14 will drive the servo slide 15 and push plate 16 to move upward. The apex and trough of the servo slide 15, i.e. the highest point and the lowest point, can also be set with limit switches to prevent the servo slide 15 and push plate 16 from colliding with the belt conveyor 3 or the mounting frame 6 when they move up and down. After the servo slide 15 and push plate 16 move upward, the push plate 16 will not interfere with the conveying of subsequent products. At the same time, the servo slide 15 will drive the push plate 16 to move in the opposite direction to reset until the internal limit switch to prevent overtravel is triggered, so as to push the next product and ensure the continuity of the assembly line operation.

[0052] If the pressure of the scraper 12 needs to be adjusted according to product specifications, or if the spring pressure decreases after prolonged use, the operator can achieve this by rotating the lead screw 8 at the top of the support frame 7. The lead screw 8 is threadedly connected to the adjusting plate 9. Rotating the lead screw 8 will drive the adjusting plate 9 to slide up and down along the support frame 7, thereby causing the spring telescopic rod 10 to extend and retract, thus adjusting the spring preload and achieving flexible adjustment of the scraper 12's pressure on the product, improving the film application stability of more product specifications. At the same time, the scraper 12 is detachably connected to the support frame 7 by bolts. When the scraper 12 is damaged, the operator can easily remove the bolts to replace the scraper 12, ensuring the continuous and stable operation of the equipment.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
