DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The two guide wheels 3 are connected to each other with a plurality of threaded rods 3. The two guide wheels 3 are connected to each other with a plurality of threaded rods 3.

[0024] Among them, one end of each two mutually cooperating telescopic plates 8 are fixedly connected to a disc 9, and the disc 9 can be moved by the extension and contraction of the telescopic plates 8. A pressure roller 10 is provided between each two mutually cooperating discs 9, and both ends of each pressure roller 10 are fixedly connected to a second rotating shaft 11. The opposite ends of each two mutually cooperating second rotating shafts 11 are provided with a slot 12 that cooperates with the corresponding disc 9. The opposite sides of the two sliding plates 5 are provided with a moving groove 13, and the inner tops of the two moving grooves 13 are installed with an electric telescopic rod 14. The telescopic ends of the two electric telescopic rods 14 are fixedly connected with a moving block 15, and the two moving blocks 15 are slidably connected to the inner walls of the corresponding moving grooves 13. The two first rotating shafts 6 located above are rotatably connected to the corresponding moving blocks 15. Through the cooperation of the electric telescopic rod 14 and the moving block 15, the pressure roller 10 located above can be moved up and down, and then the distance between the two pressure rollers 10 can be adjusted so that it can adapt to workpieces of different thicknesses;

[0025] Among them, a second motor 16 is installed on the side wall of one of the moving blocks 15, and the output shaft end of the second motor 16 passes through the corresponding moving block 15 and is fixedly connected to the corresponding first rotating shaft 6. A rotating groove 17 is opened in each disc 9, and a limiting mechanism for limiting the corresponding disc 9 is provided in each rotating groove 17. Each limiting mechanism includes a rotating rod 18 rotatably connected to the corresponding rotating groove 17, and the outer wall of each rotating rod 18 is fixedly connected to a rotating plate 19. Each rotating plate 19 is provided with a plurality of arc surfaces, and a groove is opened between two adjacent arc surfaces. The outer wall of each rotating plate 19 is slidably connected to a plurality of limiting rods 20, and each limiting rod 20 is fixedly connected to a spherical block at one end near the rotating plate 19. Each spherical block can slide on the corresponding rotating plate 19, and the inner wall of each rotating groove 17 is provided with a plurality of limiting grooves 21 cooperating with the corresponding limiting rod 20, and the outer wall of each limiting rod 20 is fixedly connected to a slider 22;

[0026] Among them, each slider 22 is elastically connected to the inner wall of the corresponding limit slot 21 by a spring 23, and each slider 22 can slide in the corresponding limit slot 21. The inner wall of each slot 12 is provided with a plurality of limit holes 24 that cooperate with the corresponding limit rod 20, and the inclination angle of each limit hole 24 is consistent with the inclination angle of the corresponding limit slot 21. Under the elastic action of multiple springs 23, multiple sliders 22 slide in the corresponding limit slot 21 until multiple spherical blocks slide into the corresponding grooves. In this way, the other ends of the multiple limit rods 20 are stuck in the corresponding limit holes 24, and the installation of the pressure roller 10 is completed. The other end of each rotating rod 18 passes through the corresponding disc 9 and extends to the outside. The end of each rotating rod 18 located at the outside is fixedly connected to a knob 25.

By adjusting the distance between the two pressure rollers 10, it is possible to adapt to workpieces of different thicknesses. When it is necessary to process workpieces of different lengths, the first motor 4 is started to rotate the bidirectional threaded rod 3, thereby moving the two sliding plates 5. By adjusting the distance between the two sliding plates 5, it is possible to install pressure rollers 10 of different lengths. After the distance between the two sliding plates 5 is adjusted, the two pressure rollers 10 can be installed in sequence.

[0028] The two pressing rollers 10 are then moved relative to each other and inserted into the corresponding slots 12 to achieve the initial fixation of the pressing roller 10. Then, the two knobs 25 are turned to rotate the two rotating rods 18 with the corresponding rotating plates 19. During the rotation of the two rotating plates 19, the spherical blocks of the multiple limiting rods 20 slide on the curved surface of the rotating plate 19. At this time, under the elastic action of the multiple springs 23, the multiple sliders 22 slide in the corresponding limiting grooves 21 until the multiple spherical blocks slide into the corresponding grooves on the rotating plate 19. In this way, the other ends of the multiple limiting rods 20 are stuck in the corresponding limiting holes 24, thereby achieving the installation of the pressing roller 10 at the bottom. The above steps can be repeated to install the pressing roller 10 at the top. In this way, the disassembly and installation of the two pressing rollers 10 are convenient and simple, and it is convenient to adjust and install pressing rollers 10 of different lengths according to workpieces of different lengths.
