Description

Technical Field

[0001] This utility model belongs to the technical field of skin trimming devices, specifically relating to a trimming device for PVC-coated skin. Background Technology

[0002] PVC coating is a technique that uses specific processes to attach PVC material to the surface of a substrate to form a protective or decorative layer.

[0003] Over time, PVC-coated skins may develop curling edges, requiring trimming to prevent the connection between the PVC-coated skin and the workpiece from gradually loosening. Currently, most PVC-coated skins are trimmed using a utility knife, which can easily scratch the workpiece surface and cause deformation of the PVC-coated skin during cutting, resulting in bending at the trimmed edge and making subsequent repairs difficult.

[0004] Therefore, a trimming device for PVC-coated skin is proposed. Summary of the Invention

[0005] This invention provides a trimming device for PVC-coated skin, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a trimming device for PVC-coated skin, including a scraper plate; a support frame disposed on the top of the scraper plate; a screw threaded to the center of the top of the support frame; a lifting plate that rotates the bottom end of the screw; a first through groove and two second through grooves opened on the top of the lifting plate, the first through groove being located between the two second through grooves; an edge trimming assembly disposed in the first through groove; and an edge pressing assembly disposed in the second through groove. The edge trimming assembly includes a cutter that slides on the inner wall of the first through groove; the edge pressing assembly includes a connecting frame that slides on the second through groove; a movable frame disposed on the top of the connecting frame; a pressure roller that rotates on the inner wall of the movable frame; a pressure block disposed on the bottom of the lifting plate near the second through groove; and a cutting groove opened on the top of the scraper plate near the cutter.

[0007] Furthermore, the top of the cutter is provided with a handle, and a cutting edge is provided on one side of the outer wall of the cutter. A cutting edge is provided on the bottom of the cutter, and a handle is provided on the top of the connecting frame.

[0008] Furthermore, a turntable is provided at the top end of the screw;

[0009] Furthermore, a guide column is provided on the inner side wall of the support frame, and the guide column passes through the lifting plate;

[0010] By adopting the above technical solution, the lifting plate is limited and guided by the guide column, ensuring that the lifting plate rises and falls vertically.

[0011] Furthermore, the bottoms of the pressure roller and the pressure block are on the same horizontal plane;

[0012] By adopting the above technical solution, when the pressure block squeezes one side of the PVC-coated skin, the pressure roller applies pushing pressure to the PVC-coated skin during the movement and rotation process, ensuring the flatness of the PVC-coated skin and thus ensuring the accuracy of subsequent cutting and trimming.

[0013] Furthermore, an inclined surface is provided on one side of the top of the shovel plate;

[0014] By adopting the above technical solution, the inclined shovel can be easily inserted between the PVC-coated skin and the workpiece, thereby trimming and removing the damaged skin edges.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention applies pressure to one side of the PVC-coated skin at the cut edge using a pressure block, and utilizes a rotating pressure roller during linear movement to squeeze the PVC-coated skin. This applies horizontal pushing pressure to ensure the cut edge of the PVC-coated skin is flat, preventing deformation and bending during cutting, thus ensuring the accuracy of subsequent cutting and trimming. It effectively trims warped edges of the PVC-coated skin without scratching the workpiece covered by the PVC-coated skin.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figure 1-4 This utility model embodiment proposes a trimming device for PVC-coated skin, including a scraper plate 1. A support frame 2 is integrally formed on one side of the top of the scraper plate 1. An inclined surface is opened on the other side of the top of the scraper plate 1. Through the inclined surface of the scraper plate 1, the scraper plate 1 can be easily inserted between the PVC-coated skin and the workpiece, thereby trimming the damaged skin edge. A screw rod 3 is threaded through and screwed into the center of the top of the support frame 2. A lifting plate 4 is rotatably connected to the bottom end of the screw rod 3. A guide post is provided on the inner side wall of the support frame 2. The guide post passes through the lifting plate 4 and limits and guides the lifting of the lifting plate 4 to ensure that the lifting plate 4 lifts vertically. A turntable 11 is provided at the top of the screw rod 3.

[0026] The top of the lifting plate 4 is provided with a through groove 5 and two through grooves 6. The through groove 5 is located between the two through grooves 6. The inner side wall of the through groove 5 is slidably connected to the cutter 71 in the trimming assembly 7. The top center of the cutter 71 is provided with a handle 72. The outer side wall of the cutter 71 is provided with a blade surface 73. The bottom of the cutter 71 is provided with a blade surface 74. The top of the shovel plate 1 is provided with a cutter groove 10 near the position directly below the cutter 71. The cutter groove 10 is adapted to the cutter 71.

[0027] The inner walls of the two through slots 6 are slidably connected to the movable frame 83 of the pressing assembly 8. The top of the two movable frames 83 is provided with a connecting frame 81. The top center of the connecting frame 81 is provided with a handle 82. The inner walls of the two movable frames 83 are rotatably connected to the pressure rollers 84. The bottom of the lifting plate 4 is provided with a pressure block 9 near the side of the two through slots 6. The bottom of the pressure rollers 84 and the pressure block 9 are on the same horizontal plane. When the pressure block 9 presses one side of the PVC covering skin, the pressure roller 84 applies pushing pressure to the PVC covering skin during the movement and rotation process, ensuring that the PVC covering skin is flat, thereby ensuring the accuracy of subsequent cutting and trimming.

[0028] The specific implementation method is as follows: When trimming the edge of the PVC-coated skin, the scraper plate 1 is inserted into the gap between the PVC-coated skin and the workpiece. The PVC-coated skin moves relative to the scraper plate 1, positioning the trimmed area of ​​the PVC-coated skin directly below the cutter 71. At this time, the turntable 11 is rotated, and the screw 3 rotates synchronously. Through the screw-on connection between the screw 3 and the support frame 2, the bottom end of the screw 3 pushes the lifting plate 4 to rise and fall linearly. The lifting plate 4 moves towards the PVC-coated skin. As the lifting plate 4 gradually moves, the pressure block 9 first contacts the PVC-coated skin and... During the pressing process, the pressure roller 84 also comes into contact with the PVC-coated surface. Then, the handle 82 is pulled to move linearly. Through the sliding connection between the moving frame 83 and the through groove 6, the pressure roller 84 rotates while moving linearly. By using the pressure roller 84 to push the PVC-coated surface, the PVC-coated surface can be flattened, ensuring that the PVC-coated surface is flat. Then, the handle 72 is pulled. Through the sliding connection between the cutter 71 and the through groove 5, the cutter 71 cuts the PVC-coated surface, and the edge of the PVC-coated surface is cut off, thus achieving the trimming of the PVC-coated surface.
