Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint-free board processing technology, specifically a paint-free board trimming device. Background Technology
[0002] Melamine-faced boards are decorative boards with a specially treated surface that can be used directly without additional painting. Due to their environmental friendliness, convenience, and aesthetic appeal, they are widely used in furniture manufacturing, interior decoration, and other fields. During the processing of melamine-faced boards, edge trimming of the wood is often required.
[0003] Chinese Patent Publication No. CN221621785U discloses a trimming device for wood processing, including a worktable. A fixed plate is fixedly connected to the upper end of the worktable, and an mounting plate is installed on the side wall of the fixed plate. A sanding belt is installed on the side wall of the mounting plate. A second threaded rod is rotatably connected to the middle of the worktable, and a second threaded block is threadedly connected to the outside of the second threaded rod. A movable plate is slidably connected to the upper surface of the worktable, and the upper end of the second threaded block is fixedly connected to the lower surface of the movable plate. With this structure, the sanding belt is used to modify the wood, and the cooperation between the second threaded rod and the second threaded block allows the movable plate to move. The movable plate can fix wood of different sizes, thus facilitating the trimming of the wood.
[0004] However, in actual use, the limited distance between the two mounting plates makes it difficult to easily replace the grinding belt, which greatly reduces work efficiency. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a paint-free board trimming device. When it is necessary to replace the sanding belt, the first rocker wheel is rotated to reduce the distance between the two transmission rollers. At this time, the sanding belt is loosened. Then, the old sanding belt is removed, and the new sanding belt is placed between the two transmission rollers. After that, the first rocker wheel is rotated in the opposite direction to drive the movable frame to move to the right, thereby increasing the distance between the two transmission rollers. The sanding belt is then taut, and the rotation of the first rocker wheel is stopped. This facilitates the replacement of the sanding belt and greatly improves work efficiency. 2. This utility model discloses a paint-free board trimming device. During use, the wood board to be processed is moved to the front of the sanding belt, and then the second rocker wheel is rotated so that the movable clamping plate drives the roller to move and fit against the front of the wood board, thereby clamping and fixing the wood board. The motor drives the sanding belt to rotate, and the wood board is trimmed during the rotation. Then the wood board is pushed to move horizontally, so that the wood board can pass through the upper end of the worktable. The wood board moves smoothly under the action of the roller, thereby completing the trimming work of the wood board. Attached Figure Description

The power output end of the motor 7 is fixedly connected to the adjacent transmission roller 6. A grinding belt 8 is provided between the two transmission rollers 6, and the two transmission rollers 6 are connected by the grinding belt 8. A groove 2 is opened on the rear side of the workbench 1. The fixed frame 4, the movable frame 5 and the grinding belt 8 are all movably inserted into the inner cavity of the groove 2. The cross-section of the fixed frame 4 and the movable frame 5 is L-shaped. The fixed frame 4 is fixedly connected to the front side of the support plate 3.
[0019] A first connecting plate 10 is fixedly connected to the rear side of the movable frame 5. A first slot 9 is provided on the support plate 3 near the right side. The first connecting plate 10 movably passes through the first slot 9. A first lead screw 11 passes through the first connecting plate 10 and is threadedly connected to the first connecting plate 10. A first fixing plate 12 is provided on both the left and right sides of the first connecting plate 10. The first fixing plate 12 is fixedly connected to the rear side of the support plate 3. The two ends of the first lead screw 11 are rotatably connected to the first fixing plate 12. A first rocker wheel 13 is fixedly connected to the right end of the first lead screw 11.
[0020] The top of the workbench 1 is provided with a movable clamping plate 14. Several rollers 15 are rotatably connected to the rear side of the movable clamping plate 14. A second connecting plate 16 is fixedly connected to the bottom of the movable clamping plate 14. A second lead screw 17 is threaded through the second connecting plate 16 and is threadedly connected to the second connecting plate 16. A second slot 20 is opened near the front side of the top of the workbench 1. The second connecting plate 16 movably passes through the second slot 20. A second fixing plate 18 is provided on both the front and rear sides of the second connecting plate 16. The second fixing plate 18 is fixedly connected to the bottom of the workbench 1. The two ends of the second lead screw 17 are rotatably connected to the second fixing plate 18. A second rocker wheel 19 is fixedly connected to the front end of the second lead screw 17.
[0021] Working Principle: This utility model discloses a trimming device for paint-free boards. During use, the wood board to be processed is moved to the front of the sanding belt 8, and the wood board is brought into contact with the front of the sanding belt 8. Then, the second rocker wheel 19 is rotated, which drives the second lead screw 17 to rotate. The second connecting plate 16 moves backward relative to the second lead screw 17 under the action of the thread. The second connecting plate 16 drives the movable clamping plate 14 to move backward. The second connecting plate 16 moves in the inner cavity of the second slot 20. The movable clamping plate 14 drives the roller 15 to move until it is in contact with the front of the wood board, thereby clamping and fixing the wood board. The motor 7 drives the sanding belt 8 to rotate, and the wood board is trimmed during the rotation. Then, the wood board is pushed to move horizontally, so that the wood board can pass through the upper end of the worktable 1. The wood board moves smoothly under the action of the roller 15, thereby completing the trimming work of the wood board.
[0022] When the grinding belt 8 needs to be replaced, the first rocker wheel 13 is rotated, which drives the first lead screw 11 to rotate. The first connecting plate 10 moves to the left relative to the first lead screw 11 under the action of the thread. The first connecting plate 10 drives the movable frame 5 to move to the left. The first connecting plate 10 moves in the inner cavity of the first slot 9, thereby reducing the distance between the two transmission rollers 6. At this time, the grinding belt 8 is relaxed. Then, the old grinding belt 8 is removed, and the new grinding belt 8 is placed between the two transmission rollers 6. Then, the first rocker wheel 13 is rotated in the opposite direction to drive the movable frame 5 to move to the right, thereby increasing the distance between the two transmission rollers 6. The grinding belt 8 is taut, and the rotation of the first rocker wheel 13 is stopped. This facilitates the replacement of the grinding belt 8 and greatly improves work efficiency.
