[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] As shown in the attached Figures 1-7The rattan grinding device shown in the figure comprises a frame 4, two bearing seats 8 are fixedly installed on the upper surface of the frame 4, a fixed shaft 22 is rotatably installed through the two bearing seats 8, a grinding wheel 3 is fixedly installed on the fixed shaft 22, and a fixed pressure wheel 2 is coaxially rotatably installed on both sides of the grinding wheel 3 through a plane thrust bearing 17, the diameters of the fixed pressure wheel 2 and the grinding wheel 3 are equal, the two fixed pressure wheels 2 are rotatably connected to the fixed shaft 22, and a transmission wheel 18 is fixedly arranged on the side of the fixed pressure wheel 2 away from the grinding wheel 3. Two slide rails 6 are fixedly installed on one side of the radial direction of the fixed pressure wheel 2, and the extension direction of the two slide rails 6 is perpendicular to the axial direction of the fixed shaft 22. The same arc-shaped sliding table 7 is installed on the two slide rails 6 through a slider. A bearing seat 8 is also installed at each end of the sliding table 7. A movable shaft 9 is installed for rotation through the two bearing seats 8. A movable pressure wheel 1 is fixedly installed on the movable shaft 9. The thickness of the movable pressure wheel 1 is equal to the total thickness of the two fixed pressure wheels 2 and the grinding wheel 3. The sliding table 7 is then connected to the operating component through transmission. The operating assembly includes a foot pedal 10, one end of which is provided with a pedal portion 11, and the other end of the foot pedal 10 is rotatably connected to the frame 4. The lower end of a transmission rod 12 is rotatably mounted on the foot pedal 10, and the upper end of the transmission rod 12 is provided with a push inclined surface 13, and the upper part of the push inclined surface 13 is inclined toward the direction of the fixed pressure wheel 2. A first return spring 14 is sheathed on the peripheral side of the transmission rod 12, and the upper end of the first return spring 14 is in contact with the transmission rod 12, and the lower end of the first return spring 14 is in contact with the frame 4. When the transmission rod 12 moves downward, the first return spring 14 is compressed; the sliding table 7 is provided with a push groove 15 that matches the push inclined surface 13, and the transmission The top of the rod 12 passes through the push groove 15 and the push slope 13 is in contact with the edge of the push groove 15. Except for the edge of one side of the push groove 15 that is in contact with the push slope 13, the other edge parts of the push groove 15 do not contact the transmission rod 12, so that the downward movement of the transmission rod 12 will drive the sliding table 7 to approach the fixed pressure wheel 2. Two second return springs 16 are also provided on the sliding table 7. One end of the second return spring 16 is fixedly connected to the sliding table 7, and the other end of the second return spring 16 is fixedly connected to the upper surface of the frame 4. When the sliding table 7 approaches the fixed pressure wheel 2, the second return spring 16 will be stretched, so that the movable pressure wheel 1 can be driven by the operating component to slide closer to or away from the fixed pressure wheel 2. The fixed pressure wheel 2, the movable pressure wheel 1 and the grinding wheel 3 are then transmission-connected to the drive motor 5 fixedly installed on the frame 4 and driven to rotate by the drive motor 5.The power output end of the driving motor 5 is provided with two belt pulleys. One of the belt pulleys is directly driven and connected to the fixed shaft 22 through a belt. The fixed shaft 22 is also provided with a matching belt pulley. Through the cooperation of the belt and the belt pulley, the fixed shaft 22 drives the grinding section wheel 3 to rotate at a high speed. The other belt pulley at the power output end of the driving motor 5 is drivingly connected to the planetary gear speed reducer 19. The speed reducer 19 is then drivingly connected to the transmission shaft 20 rotatably mounted on the machine frame 4. Four belt pulleys are fixedly arranged on the transmission shaft 20. One of the belt pulleys is drivingly connected to the speed reducer 19 through a belt, and the other three belt pulleys are respectively drivingly connected to the driving wheels 18 of the movable shaft 9 and the two fixed pressing wheels 2 through belts, thereby driving the movable pressing wheel 1 and the two fixed pressing wheels 2 to rotate slowly. The rotating speeds of the movable pressing wheel 1 and the fixed pressing wheels 2 are equal and the rotation directions are the same. The middle groove of the belt pulley on the movable shaft 9 is deeper, so that during the movement of the movable shaft 9, the corresponding belt will not fall off from the belt pulley even if it is loose. Similarly, a deeper middle groove is also provided on the other belt pulley corresponding to this belt to prevent the belt from falling off. The speed ratio of the movable pressing wheel 1, the fixed pressing wheels 2 and the grinding section wheel 3 is: movable pressing wheel 1: fixed pressing wheels 2: grinding section wheel 3 = 1:1:1500.

[0028] As a preferred embodiment, a grinding section workbench 21 is provided on the upper surface of the machine frame 4 at a position corresponding to between the movable pressing wheel 1 and the fixed pressing wheels 2. A limiting cylinder for restricting the radial displacement of the rattan is provided on the grinding section workbench 21 to prevent the rattan from detaching from the grinding section equipment during the grinding process. In practical applications, a protective cover can also be provided on the upper surface of the machine frame 4 to cover the structure on the upper surface of the machine frame 4 to improve safety. At the same time, the limiting cylinder is provided on the protective cover to make it more convenient for the rattan to be inserted.

[0029] The usage process of the grinding section equipment provided in this embodiment is as follows:

[0030] Step S1, place the rattan with rattan nodes between the movable pressing wheel 1 and the fixed pressing wheels 2 on the grinding section workbench 21 and make the rattan pass through the limiting cylinder, and push the rattan until the grinding section wheel 3 corresponds to the rattan nodes;

[0031] Step S2, step on the stepping part 11 of the foot pedal 10 downward with the foot. The foot pedal 10 rotates downward and drives the transmission rod 12 to descend. Then, the transmission rod 12 pushes the sliding table 7 towards the fixed pressing wheel 2 through the pushing inclined surface 13, so that the movable pressing wheel 1 approaches the fixed pressing wheel 2, and the movable pressing wheel 1 and the fixed pressing wheels 2 cooperate to clamp the rattan.

[0032] Step S3: Start the drive motor 5. Under the driving action of the transmission shaft 20 and each belt and pulley, the drive motor 5 drives the movable pressure wheel 1, the fixed pressure wheel 2 and the node grinding wheel 3 to rotate. The rotation speeds of the movable pressure wheel 1, the fixed pressure wheel 2 and the node grinding wheel 3 are 0.2 revolutions per second, 0.2 revolutions per second and 200 revolutions per second respectively. The rotational cooperation of the movable pressure wheel 1 and the fixed pressure wheel 2 drives the rattan to rotate slowly, and the node grinding wheel 3 rotates at a high speed and conducts high-speed friction on the rattan node until the rattan node is ground off.

[0033] Step S4: Release the foot pedal 10. Under the action of the first return spring 14 and the second return spring 16, the movable pressure wheel 1 returns to its original position and releases the rattan. At this time, the rattan can be continuously pushed to move the next rattan node to correspond to the node grinding wheel 3, and then steps S1 - S4 are repeated until all the rattan nodes are ground off.

[0034] Removing the rattan nodes by means of high-speed friction has higher efficiency and better safety. At the same time, the position of the original rattan node is smoother after grinding, which is convenient for subsequent processing.

[0035] The above embodiments only represent one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
