The base 1 is provided with a second rotating shaft 9 on the side of the lifting frame 6, and the lower end of the second rotating shaft 9 is rotatably connected with the base 1 through a bearing. The end of the first rotating shaft 5 is connected to the second rotating shaft 9 through a bevel gear. The side of the lifting frame 6 is provided with a bevel gear 10 that rotates on the side of the lifting frame 6. The end of the rotating shaft of the support wheel 2 is provided with a bevel gear that meshes with the bevel gear 10. The upper end of the second rotating shaft 9 passes through the bevel gear 10 and is slidably connected with the bevel gear 10. A guide block 11 is provided on the outer cylindrical surface of the second rotating shaft 9, and a guide groove that cooperates with the guide block 11 is provided on the inner wall of the bevel gear 10. When the first rotating shaft 5 rotates, the cam 7 rotates accordingly. Under the action of the cam 7 and the roller 8, the lifting frame 6 is continuously lifted and lowered.

Under the action of the guide block 11 and the guide groove, the bevel gear 10 rotates accordingly. When the lifting frame 6 is lifted and lowered, the support wheel 2 can rotate all the time, and there will be no situation where it cannot rotate.

[0029] like Figure 2 and Figure 3 As shown, the base 1 is symmetrically provided with upright posts 12, and the upright posts 12 are provided with cross beams 13 that are raised and lowered on the upright posts. When the lifting frame 6 is raised and lowered, the cross beam 13 is raised and lowered under the action of a first linkage mechanism, and the first linkage mechanism includes a rotating rod 14 that is rotatably connected between the middle position and the upright posts 12, and connecting rods 15 that are arranged at both ends of the rotating rod 14, and one inner end of the connecting rod 15 is rotatably connected to the end corresponding to the rotating rod 14, the upper end of the upper connecting rod 15 is rotatably connected to the cross beam 13, and the lower end of the lower connecting rod 15 is rotatably connected to the lifting frame 6. When the lifting frame 6 is raised and lowered, under the action of the rotating rod 14 and the connecting rods 15 arranged at both ends of the rotating rod 14, the cross beam 13 moves synchronously in the same direction or in the opposite direction, thereby realizing the linkage between the lifting frame 6 and the cross beam 13, which is mechanically linked, low in cost, and good in reliability.

[0030] like Figure 2 As shown, a plurality of shifting teeth 16 are evenly arranged on the outer cylindrical surface of the support wheel 2. After the support wheel 2 contacts the wood strip, the wood strip can be reliably driven to move under the action of the shifting teeth.

[0031] like Figure 3 As shown, a first guide rod 17 is provided at the lower end of the lifting frame 6 , passing through the base 1 and slidably connected to the base 1 , and the lifting frame 6 is guided to be lifted or lowered by the first guide rod 17 .

[0032] like Figure 3 As shown, a tension spring 18 is provided between the lifting frame 6 and the base 1 , and under the action of the tension spring 18 , a close fit between the cam 7 and the roller 8 is achieved.

[0033] like Figure 3 As shown, a support plate 19 is provided on the side of the lifting frame 6, and the bevel gear 10 is arranged on the support plate 19 and rotates on the support plate 19. A sleeve is provided at the lower end of the bevel gear 10, and the sleeve passes through the support plate and is rotatably connected to the support plate through a bearing.

[0034] like Figure 2 As shown, guide sleeves 20 cooperating with the columns 12 are provided at both ends of the crossbeam 13 .

[0035] like Figure 2 As shown, a buffer mechanism is provided between the pressing wheel 3 and the cross beam 13 , and when the first rotating shaft 5 rotates, the pressing wheel 3 rotates accordingly under the action of the second linkage mechanism.

[0036] like Figure 3 As shown, the buffer mechanism includes a support frame 21 for supporting the pressing wheel 3, the support frame 21 is provided with a second guide rod 22 passing through the cross beam 13 and slidably connected with the cross beam 13, the second guide rod 22 is provided with a compression spring 23, the upper end of the compression spring 23 contacts the cross beam 13, the lower end of the compression spring 23 contacts the support frame 21, and a baffle is provided at the upper end of the second guide rod 22. When the cross beam 13 descends, the pressing wheel 3 presses the wood, and the compression spring 23 plays a buffering role to prevent the wood from being crushed.

[0037] like Figure 2 As shown, the second linkage mechanism includes a No. 1 connecting rod 24, a No. 2 connecting rod 25, a No. 1 belt 26, and a No. 2 belt 27. The No. 1 connecting rod 24 is hinged to the No. 2 connecting rod 25, and a rotatable axle pin is provided at the hinge between the two. The end of the No. 1 connecting rod 24 away from the No. 2 connecting rod 25 is rotatably connected to the first rotating shaft 5, and the end of the No. 2 connecting rod 25 away from the No. 1 connecting rod 24 is rotatably connected to the rotating shaft of the pressure wheel 3. The first rotating shaft 5 is connected to the rotating shaft of the pressure wheel 3 through the No. 1 belt 26 and the No. 2 belt 27.

[0038] Since the crossbeam needs to be raised and lowered, the rotation of the pressing wheel 3 requires it to be connected to the first rotating shaft 5. The rotation of the first rotating shaft 5 drives the pressing wheel 3 to rotate, which can be achieved through the telescopic transmission assembly.

[0039] During use, when the first rotating shaft 5 rotates, it drives the No. 1 belt 26 to move, and the No. 1 belt 26 drives the No. 2 belt 27 to move, thereby causing the pressure wheel 3 to rotate accordingly. In this process, two coaxially arranged pulleys are fixed on the axle pin where the No. 1 connecting rod 24 and the No. 2 connecting rod 25 are hinged. One of the pulleys is connected to the first rotating shaft 5 through the No. 1 belt 26, and the other pulley is connected to the rotating shaft of the pressure wheel 3 through the No. 2 belt 27.
