Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood product polishing technology, specifically an automatic polishing device for bamboo and wood products. Background Technology

[0002] Bamboo and wood products are made from bamboo as raw material, which is processed through peeling, steaming, gluing, hot pressing and other processes to produce industrial bamboo plywood or decorative bamboo flooring. The most common bamboo and wood products include: chopsticks, wooden bowls, wooden spoons, toothpicks, ashtrays, steamers, chopstick holders, fruit baskets and wooden stationery.

[0003] Currently, China has publicly disclosed an automatic wood board sanding and polishing machine, with the announcement number CN221159668U. The machine features a first and a second driving roller, both located in the Z-direction and above the guide rail. The first driving roller is positioned between the side sanding roller and the upper sanding roller, while the second driving roller is located on the side of the upper sanding roller away from the side sanding roller. Both the first and second driving rollers are driven to rotate by a roller rotation drive mechanism.

[0004] Based on the above-disclosed solutions and existing technologies, in the existing technology, when polishing products, the surface that is in close contact with the conveyor belt cannot be polished. It is necessary to manually flip the product over and polish it again to ensure that the burrs are completely removed. This is time-consuming and labor-intensive, and the distance between the side polishing rollers cannot be adjusted according to the width of the product, making it difficult to adapt to the polishing of different products. Therefore, we propose an automatic polishing device for bamboo and wood products to solve the above problems. Utility Model Content

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a belt conveyor, a turning roller, and a clamping rod. The polished product is conveyed to one end of the belt conveyor via conveyor belt A. The belt conveyor then conveys the product to the surface of the clamping rod. The turning roller rotates, causing the clamping rod to rotate. When the clamping rod rotates to the other end of the belt conveyor, the product turns over and slides onto the surface of the belt conveyor. The product is then conveyed to the surface of conveyor belt B for further polishing. This method avoids the problem of the surface that is in close contact with one side of the conveyor belt not being polished, which would make it difficult to ensure the completeness of burr removal during polishing.

[0018] 2. This utility model uses a bidirectional lead screw and a side grinding roller. By rotating the handle according to the width of the product to be ground, the bidirectional lead screw is rotated, which drives the nut block on the surface to move. The nut block drives the side grinding roller to adjust according to the width of the product, making it easy to adapt to the grinding of different products. Attached Figure Description

Both ends of the turning roller 3 are rotatably connected to two mounting plates on the surface of the worktable 1, and a servo motor is mounted at one end of the turning roller 3. When the turning roller 3 turns the product, the product on the surface of the belt conveyor 2 is conveyed to the conveyor belt B4, turning... Roller 3 will flip again to convey the next product. One end of belt conveyor 2 is equipped with conveyor belt B4, and the other end of conveyor belt B4 is equipped with conveyor belt C5. Conveyor belt A9 and conveyor belt C5 are arranged in parallel. Conveyor belt B4 is located on one side of conveyor belt C5. One end of one of the drive rollers of conveyor belt B4 is fixedly connected to a bevel gear set. One end of the bevel gear set is connected to one end of one of the drive rollers of conveyor belt A9 via synchronous belt A. One end of one of the drive rollers of conveyor belt A9 is equipped with motor A. The opposite ends of the conveyor rollers on the same side of conveyor belt A9 and conveyor belt C5 are fixedly connected. The bevel gear set consists of two bevel gears.

The sanded product is transported to one end of the belt conveyor 2 via the conveyor belt A9. The belt conveyor 2 transports the product to the surface of the clamping rod 13. The flipping roller 3 rotates, driving the clamping rod 13 to rotate. When the clamping rod 13 rotates to the other end of the belt conveyor 2, the product flips over and slides onto the surface of the belt conveyor 2. The belt conveyor 2 transports the product to the conveyor belt B4, and then the conveyor belt B4 transports it to the conveyor belt C5. The un-sanded side is sanded by the sanding rollers 7. The rotating handle can be turned according to the width of the product to be sanded, so that the bidirectional lead screw 12 rotates. The rotation of the bidirectional lead screw 12 drives the nut block 11 on the surface to move. The nut block 11 drives the side sanding rollers 10 to adjust according to the width of the product, so as to adapt to the sanding of different products.
