[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a centerless grinder with a guide wheel frame that is easy to adjust the angle, including a driving box 1, a rotating seat 2 and a fixed plate 3. One side of the top of the driving box 1 is rotatably connected to the rotating seat 2, and the top of the rotating seat 2 is fixedly connected to the fixed plate 3. The fixed plate 3 is connected to a connecting frame 4 through a connecting mechanism, and assembly blocks 5 are symmetrically provided on both sides of the connecting frame 4. A rotating motor is installed on one side of the connecting frame 4, and a rubber roller 6 is installed inside the connecting frame 4 through an assembly mechanism. An angle adjustment mechanism is provided between the driving box 1 and the rotating seat 2, and the rubber roller 6 is installed inside the connecting frame 4 through the assembly mechanism, and then the connecting frame 4 is installed on the outside of the fixed plate 3 through the connecting mechanism. The rotating motor drives the rubber roller 6 to rotate on the inner side of the connecting frame 4, and then drives the rubber roller 6 to move toward the grinding material through the angle adjustment mechanism, so that the two sides of the grinding material are respectively fitted with the rubber roller 6 and the grinding roller, driving the grinding rotation while also grinding its surface smoothly.

[0020] The assembly mechanism includes a No. 1 plug rod 8 and a No. 2 clamping block 10. The assembly block 5 is provided with a No. 1 plug rod 8 inside, and multiple No. 2 clamping blocks 10 are fixed on the outside of the No. 1 plug rod 8. The rubber roller 6 is provided with a spline groove inside, and the No. 1 plug rod 8 is connected with the spline groove through the No. 2 clamping block 10. First, place the rubber roller 6 into the inside of the connecting frame 4, and make the center of the rubber roller 6 and the assembly block 5 parallel to each other, and then align the position of the No. 2 clamping block 10 with the spline groove, and then insert the No. 1 plug rod 8 into the inside of the rubber roller 6 through the assembly block 5. At this time, the No. 1 plug rod 8 is fixed together with the rubber roller 6.

[0021] The output end of the rotating motor is fixedly connected to a rotating shaft 7, and a No. 1 clamping block 9 is symmetrically fixedly connected to the outer side of the rotating shaft 7. A rectangular clamping groove is symmetrically provided on the inner side of the No. 1 plug rod 8. The outer side of the rotating shaft 7 is clamped and connected with the inner side of the No. 1 plug rod 8 through the No. 1 clamping block 9. One end of the rotating shaft 7 is fixedly connected to the output end of the rotating motor. Then, the rubber roller 6 is rotated to align the rectangular clamping groove on the inner side of the No. 1 plug rod 8 with the No. 1 clamping block 9 on the outer side of the rotating shaft 7. The rubber roller 6 is pushed to clamp the No. 1 clamping block 9 and the rectangular clamping groove together, so that the No. 1 plug rod 8 is connected to the output end of the rotating motor through the rotating shaft 7. The rotating motor can drive the rubber roller 6 to rotate on the inner side of the connecting frame 4.

[0022] A threaded hole is provided inside the assembly block 5, and a pressure cover 11 is provided on one side of the assembly block 5. A threaded column 12 is fixedly connected to one side of the pressure cover 11. The outer wall of the threaded column 12 is threadedly connected to the inner wall of the threaded hole. A hexagonal hole is provided inside the pressure cover 11. After the threaded column 12 is aligned with the threaded hole, a hexagonal wrench is inserted into the hexagonal hole, and the threaded column 12 is screwed into the threaded hole. The threaded hole is closed by the pressure cover 11 to prevent the No. 1 insertion rod 8 inserted into the rubber roller 6 from falling out of the threaded hole. When the rubber roller 6 needs to be removed from the connecting frame 4, the pressure cover 11 is removed from the connecting frame 4 using a hexagonal wrench, which is convenient for people to pull out the No. 1 insertion rod 8 from the inside of the rubber roller 6.

[0023] The angle adjustment mechanism includes a worm gear 13, a worm 14 and a drive motor 15. The worm gear 13 is fixed to the outer side of the rotating seat 2. The worm 14 is rotatably installed inside the driving box 1. The outer wall of the worm 14 meshes with the outer wall of the worm gear 13. The drive motor 15 is installed on the outer side of the driving box 1. The output end of the drive motor 15 is fixedly connected to one end of the worm 14. The drive motor 15 can drive the worm 14 to rotate inside the driving box 1. The worm 14 and the worm gear 13 mesh with each other. When the worm 14 rotates, the rotating seat 2 can be driven to rotate. The rubber roller 6 is connected to the fixed plate 3 through the connecting frame 4 to automatically adjust the angle of the rubber roller 6.

[0024] A connecting rod 16 is fixedly connected to one side of the fixing plate 3, and a No. 2 plug rod 17 is fixedly connected to the outer side of the connecting frame 4. One end of the No. 2 plug rod 17 is inserted into the interior of the connecting rod 16, and a connecting bolt is passed through the No. 2 plug rod 17 and the connecting rod 16, and nuts are threadedly connected at both ends of the connecting bolt. One end of the No. 2 plug rod 17 is inserted into the interior of the connecting rod 16, and then the connecting bolt is inserted into the junction of the No. 2 plug rod 17 and the connecting rod 16, and nuts are tightened at both ends of the connecting bolt to fix the No. 2 plug rod 17 and the connecting rod 16 together.

[0025] A flange is provided on one side of the driving motor 15 , and a group of mounting holes are symmetrically provided on both sides of the flange. Fixing bolts are provided inside the mounting holes, and the flange is detachably connected to the outer side of the driving box 1 through the fixing bolts.

[0026] The guide wheel frame of the centerless grinder first places the rubber roller 6 into the interior of the connecting frame 4, and makes the centers of the rubber roller 6 and the assembly block 5 parallel to each other, and then aligns the No. 2 clamping block 10 with the position of the spline groove, and then inserts the No. 1 plug rod 8 into the interior of the rubber roller 6 through the assembly block 5. At this time, the No. 1 plug rod 8 is fixed together with the rubber roller 6, and then the rubber roller 6 is rotated to make the rectangular slot inside the No. 1 plug rod 8 aligned with the No. 1 clamping block 9 outside the rotating shaft 7, and the rubber roller 6 is pushed to clamp the No. 1 clamping block 9 with the rectangular slot together, and after aligning the threaded column 12 with the threaded hole, insert the hexagonal wrench into the hexagonal hole, screw the threaded column 12 into the threaded hole, and use the pressure cover 11 to close the threaded hole, so as to solve the problem in the prior art that a large number of bolts need to be removed when dismantling the guide wheel frame when inspecting the inside of the machine, and the operation is relatively cumbersome and laborious, which reduces the convenience of the device.
