Description

Technical Field

[0001] This utility model relates to the field of plastic surface coating technology, and in particular to a plate-shaped plastic coating bonding tooling. Background Technology

[0002] In the surface protection and decoration processes of sheet plastics (such as PVC, PMMA, PC extruded sheets, or foamed sheets), lamination is a routine procedure. Current practices typically involve two steps: first, a protective or decorative film is laid on the surface of the sheet, and then the entire sheet is fed into a pressure roller machine or vacuum laminator for pressing. Because the laminating equipment is large, energy-intensive, and requires multiple handling operations, it not only occupies a large space but is also prone to defects such as film misalignment, bubbles, and wrinkles. Furthermore, traditional pressure roller machines use fixed large rollers, which are poorly adapted to short-sized, small-batch sheet plastics, and require long setup and commissioning times, making it difficult to meet the needs of flexible production with multiple specifications.

[0003] To address these issues, the industry has developed several miniaturized, manual, or semi-automatic lamination fixtures. These fixtures typically place the heated sheet material on a platform after lamination and use a flipping plate or frame to allow the laminated sheet plastic to cool naturally, preventing the film from shrinking or peeling under high temperature or stress. While the structure is simple, it suffers from a problem: because the coefficient of thermal expansion of the film differs from that of the sheet plastic under high temperature or stress, air bubbles can easily form within the film. The lamination fixture cannot automatically remove these air bubbles. Utility Model Content

[0004] The purpose of this invention is to provide a plate-shaped plastic film laminating tool to solve the problem mentioned in the background art that existing film laminating tools have air bubbles in the film layer that cannot be discharged.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sheet-like plastic film laminating fixture, including a laminating table, the top surface of which is provided with a support platform for placing sheet-like plastic, and a flip cover is provided above the support platform; The laminating table has receiving grooves on both sides, and a hinge is provided in the receiving groove. The hinge is used to connect the laminating table and the flip cover. The flip cover can move laterally along the film-coating platform, and the receiving groove is provided with a snap-fit ​​component, which is used to fix the flip cover after it has been moved. The flip cover has guide holes at both ends, and a pressure roller that moves along the guide holes is provided in the inner cavity of the flip cover. The flip cover also has elastic elements at both ends, which are used to squeeze the pressure roller. The top surface of the laminating table is provided with a movable plate, and the top surface of the laminating table is provided with two limiting grooves. Each of the two limiting grooves is provided with a reset member. The reset member is used to drive the movable plate after movement to reset along the limiting groove. The movable plate is used to push the flip cover to move laterally on the laminating table. The side of the movable plate closest to the flip cover is fixedly connected to a rear edge plate, and the side of the flip cover closest to the movable plate is fixedly connected to a front edge plate. The rear edge plate abuts against the front edge plate to drive the flip cover to move laterally after flipping.

[0006] Preferably, the hinge includes a guide plate fixed to the bottom surface of the flip cover, the inner cavity of the guide plate is provided with a guide groove, and an insert rod is fixedly connected to the inner cavity of the receiving groove. One end of the insert rod extends into the guide groove and is slidably connected to the guide groove.

[0007] Preferably, the latching component includes a latching plate fixed to the bottom of the flip cover, the latching plate having a latch at the end away from the flip cover, a side plate fixedly connected to the top surface of the film-coating table, and a latching rod adapted to the latch fixedly connected to one side of the side plate.

[0008] Preferably, the elastic element includes a fixed plate fixed to the side wall of the flip cover, a connecting plate located on the outside of the flip cover is rotatably connected to the top of the pressure roller, a telescopic rod is fixedly connected between the fixed plate and the connecting plate, a spring is sleeved on the outer wall of the telescopic rod, and the two ends of the spring are fixedly connected to the fixed plate and the connecting plate respectively.

[0009] Preferably, the bottom surface of the rear edge plate is higher than the top surface of the front edge plate in the vertical direction.

[0011] The technical effects and advantages of this utility model are as follows: After the sheet-like plastic is coated with film, the flip cover is rotated and flipped. The inside of the flip cover is pressed by a pressure roller, which makes the film layer adhere to the sheet-like plastic. At the same time, the flip cover is moved by a moving plate, which in turn moves the pressure roller at the bottom, thereby rolling and pressing the film layer to adhere it. This avoids the film layer from shrinking and lifting at the edges, and at the same time squeezes out the air bubbles in the film layer. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] It includes a laminating table 1, the top surface of which is provided with a support platform 12 for placing sheet-shaped plastic, and a flip cover 2 is provided above the support platform 12. The laminating table 1 has receiving grooves 11 on both sides, and hinges are provided in the receiving grooves 11. The hinges are used to connect the laminating table 1 and the flip cover 2. The flip cover 2 can move laterally along the film covering table 1. The receiving groove 11 is provided with a snap-fit ​​component, which is used to fix the flip cover 2 after it has been moved. The flip cover 2 has guide holes 24 at both ends, and a pressure roller 23 that moves along the guide holes 24 is provided in the inner cavity of the flip cover 2. The flip cover 2 has elastic elements 4 at both ends, and the elastic elements 4 are used to squeeze the pressure roller 23. The top surface of the laminating table 1 is provided with a movable plate 3, and the top surface of the laminating table 1 is provided with two limiting grooves 16. The two limiting grooves 16 are provided with a reset member 6. The reset member 6 is used to drive the movable plate 3 to reset along the limiting groove 16 after the movement. The movable plate 3 is used to push the flip cover 2 to move laterally on the laminating table 1. A rear edge plate 32 is fixedly connected to the side of the movable plate 3 near the flip cover 2, and a front edge plate 25 is fixedly connected to the side of the flip cover 2 near the movable plate 3. The rear edge plate 32 abuts against the front edge plate 25 to drive the flip cover 2 to move laterally after flipping.

[0021] After lamination, existing lamination and bonding fixtures typically use a cover plate to press and cool the film to prevent edge lifting or shrinkage. However, during the cooling process, due to the difference in expansion coefficients between the film and sheet plastic, air bubbles are easily generated inside the film, which existing lamination fixtures cannot remove on their own. refer to Figure 1-6 It is understood that in this embodiment, a heated plate of plastic is first placed on the support platform 12, and a film is manually applied to the plate of plastic. After the film is applied, the flip cover 2 is flipped by the hinges in the receiving grooves 11 on both sides of the film application platform 1, so that the flip cover 2 covers the plate of plastic. Immediately after the covering is completed, the pressure roller 23 inside the flip cover 2 squeezes the top surface of the sheet-like plastic film layer. It is worth noting that the pressure roller 23 consists of an inner shaft and a rubber layer surrounding the inner shaft. When the pressure roller 23 squeezes the film layer, the rubber layer of the pressure roller 23 contacts the bottom surface of the film layer to avoid damaging the film layer and causing wrinkles. At the same time, the two ends of the pressure roller 23 can move along the guide hole 24. The pressure between the pressure roller 23 and the film layer is adjusted by the elastic element 4 to ensure the adhesion between the pressure roller 23 and the film layer. Finally, the resetting member 6 in the limiting groove 16 drives the moving plate 3 to move. The moving plate 3 pushes the flip cover 2 to move on the film coating table 1, thereby causing the pressure roller 23 inside the flip cover 2 to expel the air bubbles in the film layer. After the air bubbles are expelled, when it is necessary to fix the flip cover 2 that is moving on the film coating table 1, the flip cover 2 is fixed by the snap-fit ​​member to continuously press and cool the plate-shaped plastic after film coating.

[0022] This application involves flipping a cover 2 after coating a sheet-like plastic with film. The inside of the cover 2 is fitted with a pressure roller 23, which allows the film to adhere to the sheet-like plastic. At the same time, the flip cover 2 is moved by a moving plate 3, which in turn moves the pressure roller 23 at the bottom, thereby squeezing and bonding the film. This prevents the film edges from shrinking and lifting, while also squeezing out air bubbles in the film.

[0023] In embodiment 2, the hinge includes a guide plate 21 fixed to the bottom surface of the flip cover 2. The guide plate 21 has a guide groove 22 inside. A rod 15 is fixedly connected in the inner cavity of the receiving groove 11. One end of the rod 15 extends into the guide groove 22 and is slidably connected to the guide groove 22.

[0024] The snap-fit ​​component includes a snap plate 5 fixed to the bottom of the flip cover 2. The snap plate 5 has a snap slot 51 at the end away from the flip cover 2. A side plate 13 is fixedly connected to the top surface of the film covering table 1. A snap rod 14 that matches the snap slot 51 is fixedly connected to one side of the side plate 13.

[0025] Based on Embodiment 1, refer to Figure 2 , Figure 3 and Figure 6 It is understood that the hinge of this application includes a guide plate 21 fixed to the bottom of the flip cover 2. The guide plate 21 has a guide groove 22 inside. The inner cavity of the receiving groove 11 is fixedly connected to the insertion rod 15 inserted into the guide groove 22, so that the flip cover 2 is connected to the film coating table 1. When the flip cover 2 is placed horizontally, the flip cover 2 can drive the guide groove 22 of the guide plate 21 to slide at one end of the insertion rod 15, so that the moving plate 3 can drive the flip cover 2 to move on the film coating table 1, which facilitates the flip cover 2 to drive the pressure roller 23 to move and squeeze out the air bubbles in the film layer. In addition, after the air bubbles in the film layer are squeezed out, the flip cover 2 is moved to the end of the film covering platform 1 away from the moving plate 3, so that the latch 51 of the clamping plate 5 is on the outer wall of the clamping rod 14 fixed on the side plate 13, thereby fixing the clamping plate 5 and the flip cover 2. After cooling for a period of time, the flip cover 2 can be opened.

[0026] In embodiment 3, the elastic element 4 includes a fixed plate 41 fixed to the side wall of the flip cover 2, a connecting plate 43 located on the outside of the flip cover 2 is rotatably connected to the top of the pressure roller 23, a telescopic rod 42 is fixedly connected between the fixed plate 41 and the connecting plate 43, and a spring 44 is sleeved on the outer wall of the telescopic rod 42. The two ends of the spring 44 are fixedly connected to the fixed plate 41 and the connecting plate 43 respectively.

[0027] Based on Embodiment 1, refer to Figure 2 It is understandable that when the pressure roller 23 presses down, the pressure roller 23 moves upward along the guide hole 24. The pressure roller 23 drives the connecting plate 43 to move upward. When the connecting plate 43 moves upward, the telescopic rod 42 and the spring 44 are deformed through the fixing plate 41, so as to avoid the pressure roller 23 rigidly squeezing the film layer, causing imprints on the film layer and resulting in damage to the film layer.

[0028] In embodiment four, the bottom surface of the rear edge plate 32 is higher than the top surface of the front edge plate 25 in the vertical direction.

[0029] Based on Example 1 Reference Figure 1 and Figure 4 It is understandable that when the moving plate 3 pushes the flip cover 2 to move, the rear edge plate 32 of the moving plate 3 will press down on the front edge plate 25 of the flip cover 2, so that the flip cover 2 generates a downward force, thereby making the pressure roller 23 closely adhere to the film layer, avoiding the situation where the thickness of the sheet plastic is too low and the pressure roller 23 cannot press the film layer.

[0030] In embodiment 5, the reset component 6 includes a guide rod 61 fixedly connected in the limiting groove 16, a sleeve plate 62 slidably sleeved on the outer wall of the guide rod 61, the top surface of the sleeve plate 62 being fixedly connected to the bottom surface of the moving plate 3, a second spring 63 sleeved on the outer wall of the guide rod 61, the two ends of the second spring 63 being fixedly connected to the side wall of the limiting groove 16 and the side wall of the sleeve plate 62 respectively, and a handle 31 being fixedly connected to the side of the moving plate 3 away from the flip cover 2.

[0031] Based on Embodiment 1, refer to Figure 1 , Figure 3 ,and Figure 5 It is understandable that when the flip cover 2 is lifted to cover the film, the handle 31 first moves the moving plate 3 to the end away from the film covering table 1. At this time, the moving plate 3 drives the sleeve plate 62 to move along the surface of the guide rod 61. The movement of the sleeve plate 62 causes the spring 63 to deform under pressure. When the handle is released, the spring 63 returns to its original position and pushes the moving plate 3 to move. Then, the moving plate 3 drives the flip cover 2 to move, thereby enabling the pressure roller 23 to squeeze and remove the air bubbles generated in the film layer.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
