Description

Technical Field

[0001] This utility model relates to the field of sheet coating technology, specifically to a sheet coating splicing device. Background Technology

[0002] Currently, in the production process of plastic sheet products, the lamination process is an important step to improve the appearance quality and enhance the protective performance of the product. This process uses specific equipment to attach the lamination material to the surface of the plastic sheet to achieve the purposes of beautification and protection. However, in the existing lamination process, especially when it involves the replacement and connection of lamination materials, there are a series of problems that need to be solved.

[0003] A search revealed that patent CN215151820U discloses a plastic sheet laminating device. This patent uses a structure consisting of a base, rotating roller, vertical plate, hydraulic cylinder, lifting frame, and laminating roller, combined with adjusting wheel, limiting ring, and first pressing wheel to ensure laminating effect. The design is simple and practical. However, when the old laminating material is used up and new laminating material needs to be introduced for docking, the lack of a stable operating platform means that the docking process is carried out in mid-air. This docking method is not only difficult to operate, but also prone to misalignment, which affects the final laminating effect and overall aesthetics of the product. In addition, due to the short docking time, operators often find it difficult to complete the precise docking operation in a short time, thus increasing the risk of the laminating material not docking properly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects in the existing technology by adding a placement platform at the outlet of the coating material, so that the beginning and end of the new and old coating materials can be stopped at any time for easy docking.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a sheet coating and splicing device, comprising:

[0006] The frame is divided into a discharge end and a feed end, and the feed end is connected to the discharge port of the device for placing the coating material.

[0007] A placement platform is located within the frame, and a limiting component is provided on the placement platform;

[0008] The limiting component includes a telescopic component and an extrusion component connected to the telescopic component. A placement space is formed between the extrusion component and the placement platform. The coating material extends from the feed end, passes through the placement space, and reaches the discharge end.

[0009] The telescopic component is adapted to move the extrusion component to adjust the size of the placement space or to extrude the coating material passing through the placement space.

[0010] Furthermore, the extrusion component is a pressure roller, which is adapted to be driven to move by the telescopic component.

[0011] Furthermore, two pressure rollers are provided, and the two pressure rollers are symmetrically arranged on the placement platform.

[0012] Furthermore, the telescopic component is an adjusting cylinder, the fixed end of which is connected to the placement platform, and the telescopic end of which is connected to the pressure roller.

[0013] Furthermore, the placement platform is provided with a support component, which includes a left drive roller and a right drive roller rotatably disposed on both sides of the placement platform. Both the left drive roller and the right drive roller are adapted to support the film material passing through the placement space.

[0014] Furthermore, a left connecting plate and a right connecting plate are fixedly connected to both sides of the placement platform, the left transmission roller is rotatably installed in the left connecting plate, and the right transmission roller is rotatably installed in the right connecting plate.

[0015] Furthermore, the left connecting plate and the right connecting plate are positioned oppositely on the placement platform, with one located above the placement platform and the other below it.

[0016] Furthermore, a right cavity is provided in the right connecting plate and a left cavity is provided in the left connecting plate. Both the left cavity and the right cavity are connected to the placement space. The left cavity and the right cavity are adapted to provide space for the coating material to pass around.

[0017] Furthermore, the frame is provided with a traction component, which includes an upper drive roller rotatably mounted at the discharge end and a lower drive roller rotatably mounted at the feed end. The upper drive roller is adapted to support the coating material located at the discharge end, and the lower drive roller is adapted to support the coating material located at the feed end.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:

[0019] 1. Through the setting of structures such as pressure rollers and adjusting cylinders, a placement space is formed between the pressure rollers and the placement platform, which allows the coating material to pass through. The adjusting cylinder changes the size of the placement space by moving the pressure rollers to accommodate coating materials of various thicknesses. At the same time, the adjusting cylinder can move the pressure rollers toward the placement platform to squeeze and fix the coating material passing through the placement space, which facilitates the stable connection of new and old coating materials.

[0020] 2. By setting up left and right drive rollers in opposite positions on both sides of the placement platform, the coating material passing through the placement space is routed around the left and right drive rollers respectively, thereby improving the support force on the coating material, improving the stability of the coating material conveying, and further improving the stable connection between the new and old coating materials.

[0031] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] Example 1

[0033] like Figure 1 , Figure 4 As shown, a sheet coating splicing device includes:

[0034] The frame 1 is divided into a discharge end 11 and a feed end 12. The feed end 12 is connected to the discharge port of the device for placing the coating material.

[0035] Placement platform 3 is located inside frame 1, and limit components 4 are provided on placement platform 3;

[0036] The limiting component 4 includes a telescopic component and an extrusion component connected to the telescopic component. The extrusion component and the placement platform 3 form a placement space 43. The coating material extends from the feed end 12 and passes through the placement space 43 to the discharge end 11.

[0037] The telescopic component is adapted to move the extrusion component to adjust the size of the placement space 43 or to extrude the coating material passing through the placement space 43.

[0038] like Figure 3-4 As shown, the extrusion component is a pressure roller 41, which is adapted to be driven to move by a telescopic component.

[0039] like Figure 3-4 As shown, there are two pressure rollers 41, which are symmetrically arranged on the placement platform 3.

[0040] like Figure 4 As shown, the telescopic component is an adjusting cylinder 42. The fixed end of the adjusting cylinder 42 is connected to the placement platform 3, and the telescopic end of the adjusting cylinder 42 is connected to the pressure roller 41.

[0041] The working principle of this embodiment is as follows:

[0042] When in use, the entire equipment is connected to the outlet of the device for placing the coating material. The coating material enters from the feed end 12 of the frame 1, passes through the placement space 43 from one side of the placement platform 3, and then extends from the other side of the placement space 43 to the discharge end 11 of the frame 1 to coat the sheet.

[0043] The upper part of the coating material located in the placement space 43 is restricted by the pressure roller 41. Depending on the thickness of the coating material, the pressure roller 41 can be moved by the telescopic cylinder, thereby changing the size of the placement space 43 to accommodate various specifications of coating materials.

[0044] When the coating material is almost used up, it needs to be replaced with a new coating material. The head of the new coating material needs to be joined with the tail of the old coating material. To avoid uneven joining in mid-air, which is difficult and unstable, the tail of the old coating material and the head of the new coating material can be placed in the placement space 43. The telescopic cylinder drives the pressure roller 41 to move towards the placement platform 3 until the head of the new coating material and the tail of the old coating material are squeezed and fixed. The fixed two sections are easier for the operator to join, making the joining of the new and old coating materials more stable and convenient.

[0045] Example 2

[0046] like Figure 4As shown, this embodiment further includes the following structure based on embodiment one: a support component 5 is provided on the placement platform 3. The support component 5 includes a left transmission roller 54 and a right transmission roller 52 rotatably disposed on both sides of the placement platform 3. Both the left transmission roller 54 and the right transmission roller 52 are suitable for supporting the film material passing through the placement space 43.

[0047] like Figure 4 As shown, a left connecting plate 53 and a right connecting plate 51 are fixedly connected to both sides of the platform 3, respectively. The left transmission roller 54 is rotatably installed in the left connecting plate 53, and the right transmission roller 52 is rotatably installed in the right connecting plate 51.

[0048] like Figure 4 As shown, the left connecting plate 53 and the right connecting plate 51 are in opposite positions on the placement platform 3, with one located above the placement platform 3 and the other located below the placement platform 3.

[0049] like Figure 4-5 As shown, a right cavity 55 is provided in the right connecting plate 51, and a left cavity 56 is provided in the left connecting plate 53. Both the left cavity 56 and the right cavity 55 are connected to the placement space 43. The left cavity 56 and the right cavity 55 are suitable for providing space for the coating material to pass around.

[0050] like Figure 2 As shown, a traction component 2 is provided on the frame 1. The traction component 2 includes an upper drive roller 21 rotatably mounted at the discharge end 11 and a lower drive roller 22 rotatably mounted at the feed end 12. The upper drive roller 21 is adapted to support the film material located at the discharge end 11, and the lower drive roller 22 is adapted to support the film material located at the feed end 12.

[0051] The working principle of this embodiment is as follows:

[0052] Two connecting plates are set on both sides of the placement platform 3, one higher and one lower. Each connecting plate is equipped with a drive roller. In this embodiment, the higher one is the right connecting plate 51 and the right drive roller 52, and the lower one is the left connecting plate 53 and the left drive roller 54.

[0053] When the coating material enters the frame 1 from below, it abuts against the lower drive roller 22 and is then guided to the bottom of the right drive roller 52. It extends into the right cavity 55 of the right connecting plate 51, passes through the placement space 43, passes through the left cavity 56 on the left connecting plate 53, then goes around from below the left drive roller 54 to above the left drive roller 54. After coming out from above the left drive roller 54, it passes through the placement space 43 again and enters the right cavity 55. At this time, it is located below the right drive roller 52. Then it goes around along the right side of the right drive roller 52 to above the right drive roller 52, and finally is pulled to the upper drive roller 21.

[0054] The interlocking arrangement of the left drive roller 54 and the right drive roller 52 in the right cavity 55 and the left cavity 56 provides stable support for the coating material. At the same time, the lower drive roller 22 supports and pulls the coating material at the feed end 12, and the upper drive roller 21 supports and pulls the coating material at the discharge end 11, making the transmission structure more stable.

[0055] During the transmission process, the coating material located at the placement platform 3 is always located in the placement space 43, that is, between the placement platform 3 and the pressure roller 41, so as to ensure that when the new and old coating materials are joined, the beginning and end parts of the two materials can be effectively fixed and limited at the placement space 43.

[0056] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
