[0022] like Figures 1 to 4 As shown, the present invention provides a grinding device for processing bamboo and wood products, including a support plate 1;

[0023] A transmission box 2 is fixedly connected to the top of the support plate 1. A moving groove 3 is opened at the bottom of the transmission box 2. A rotating rod 4 is set at the top of the transmission box 2. The bottom of the rotating rod 4 extends into the interior of the transmission box 2 and is movably connected to the bottom of the inner wall of the transmission box 2 through a bearing. A lifting plate 5 is threadedly connected to the surface of the rotating rod 4. The surface of the lifting plate 5 is slidably connected to the inner wall of the transmission box 2. Connecting rods 6 are fixedly connected to both sides of the bottom of the lifting plate 5. The bottom of the connecting rods 6 extends into the interior of the moving groove 3 and is fixedly connected to the mounting sleeve 7. The surface of the mounting sleeve 7 is slidably connected to the inner wall of the moving groove 3. A motor 8 is fixedly connected to the left side of the mounting sleeve 7. The left side of the motor 8 extends through to the left side of the transmission box 2. The output end of the motor 8 extends into the interior of the mounting sleeve 7 and is movably connected to the inner wall of the mounting sleeve 7 through a bearing. A grinding roller 9 is fixedly connected to the surface of the output end of the motor 8. Sandpaper 10 is pasted on the surface of the grinding roller 9.

[0024] refer to Figure 3 The top of the support plate 1 has a limiting groove 11. The bottom of the inner wall of the limiting groove 11 is fixedly connected to four springs 12. The top of the springs 12 is fixedly connected to a placement plate 13. The inside of the placement plate 13 is slidably connected to four limiting rods 14. The bottom of the limiting rods 14 extends into the inside of the limiting groove 11 and is fixedly connected to the bottom of the inner wall of the limiting groove 11.

[0025] As a technical optimization of this utility model, by setting a limiting groove 11, a spring rebounder 12, a placement plate 13 and a limiting rod 14, the bamboo and wood products can move downward when squeezed by the grinding roller 9, preventing the grinding roller 9 from pressing down too much and causing damage to the surface of the bamboo and wood products.

[0026] refer to Figure 1 The top of the placement plate 13 is provided with a placement groove 15, which is used in conjunction with the placement plate 13.

[0027] As a technical optimization of this utility model, by setting the placement groove 15, the bamboo and wood products can be limited, thus preventing the bamboo and wood products from tilting and moving during the grinding process.

[0028] refer to Figure 4 The transmission box 2 has two vertically fixed guide rods 16 inside, which pass through the lifting plate 5 and are slidably connected to the lifting plate 5.

[0029] As a technical optimization of this utility model, by setting the guide rod 16, the lifting plate 5 can be guided, thereby improving the stability of the lifting plate 5 when it moves.

[0030] refer to Figure 1 The top of the transmission box 2 is provided with a rotating block 17, and the bottom of the rotating block 17 is fixedly connected to the top of the rotating rod 4.

[0031] As a technical optimization of this utility model, by setting the rotating block 17, it is easier for the user to rotate the rotating rod 4, thereby improving the user's comfort.

[0032] refer to Figure 1 A baffle 18 is fixedly connected to the top of the limiting rod 14, and the surface of the baffle 18 is slidably connected to the inner wall of the placement plate 13.

[0033] As a technical optimization of this utility model, by setting the baffle 18, the placement plate 13 can be limited, and the placement plate 13 will disengage from the limiting rod 14.

[0034] The working principle and usage process of this utility model are as follows: First, place the bamboo or wood product on top of the placement plate 13. After placement, rotate the rotating block 17. The rotating block 17 drives the rotating rod 4 to rotate. The rotating rod 4 drives the lifting plate 5 to move downwards via a thread. The lifting plate 5 drives the connecting rod 6 to move downwards. The connecting rod 6 drives the mounting sleeve 7 to move downwards. The mounting sleeve 7 drives the motor 8 and the grinding roller 9 to move downwards. The grinding roller 9 drives the sandpaper 10 to move downwards so that the bottom of the sandpaper 10 contacts the top of the bamboo or wood product. If the grinding roller 9 presses down excessively during contact, the spring force of the spring mechanism 12 drives the placement plate 13 to move downwards, causing the placement plate 13 to move the bamboo or wood product downwards, preventing the grinding roller 9 from damaging the surface of the bamboo or wood product. Finally, start the motor 8, which drives the grinding roller 9 to rotate. The grinding roller 9 polishes the surface of the bamboo or wood product using the sandpaper 10 on its surface.

[0035] In summary, this grinding device for processing bamboo and wood products, by incorporating a mounting sleeve 7, a motor 8, a grinding roller 9, and sandpaper 10, can grind the surface of bamboo and wood products, improving the practicality of the grinding machine. By incorporating a rotating block 17, a rotating rod 4, a lifting plate 5, and a connecting rod 6, the grinding roller 9 can be manually moved up and down, preventing the grinding roller 9 from having a fixed stroke and being unable to grind bamboo and wood products of different sizes. Furthermore, by incorporating a limiting groove 11, a springback mechanism 12, and a placement plate 13, the device can move compressed bamboo and wood products downwards, preventing the grinding roller 9 from directly squeezing them. The grinding process addresses the issue of surface damage caused by bamboo and wood products. This improvement offers the advantage of easily adjustable grinding height, solving the problems of current grinding machines that use hydraulic cylinders to drive grinding rollers in vertical reciprocating motion. These problems stem from the fact that the single linear stroke of the hydraulic cylinder is only suitable for bamboo and wood products of a specific diameter, leading to intermittent or overloaded contact between the grinding roller and the workpiece, resulting in uneven surface grinding or increased equipment vibration. Furthermore, changing to workpieces of different diameters requires stopping the machine to adjust the hydraulic cylinder stroke parameters, reducing batch production efficiency. Frequent adjustments can also cause wear on hydraulic system seals, reducing the practicality of the grinding machine.
