The limiting assembly 2 is fixedly mounted on the surface of the bearing assembly 3 close to the side where the polishing roller 1 is mounted. Among them, the guide seat 4 includes side connecting plates 43, and the side connecting plates 43 are provided with two groups. The two groups of side connecting plates 43 are symmetrically arranged on both sides of the outer surface of the bearing component 3. The surface of the side connecting plate 43 away from the motor 6 is fixedly installed with a frame plate 42, and the top of the frame plate 42 is threadedly connected with a cross plate 41, and the side of the cross plate 41 away from the frame plate 42 is fixedly connected to the motor 6, and a positioning block 47 is fixedly installed at the middle of the top of the side connecting plate 43, and a through rod 46 is fixedly installed between the opposite surfaces of the positioning block 47, and a connecting plate 49 is slidably installed on the surface of the through rod 46 away from the polishing roller 1. The staff places the plate on the supporting component 3, and sprays water into the suction cup 33 through the water spray pipe 31, so that the plate is adsorbed and fixed by the suction cup 33, and then the staff pushes the supporting component 3 to displace it toward the side of the polishing roller 1, so that the plate contacts the surface of the limiting component 2, and the limiting component 2 is fit and fixed to the surface of the plate. As the plate continues to displace toward the side of the polishing roller 1, the bottom of the plate and the suction cup 33 are scraped by the cross plate 41 and gradually separated. The staff starts the motor 6 so that the output end of the motor 6 drives the polishing roller 1 to rotate, and the plate is polished, thereby improving the efficiency of plate processing and material taking.

[0023] A threaded rod 45 passes through the middle of the connecting plate 49, and the threaded rod 45 is rotatably installed inside the connecting plate 49. A pulley 48 is sleeved between the threaded rod 45 and the connecting plate 49. A limit plate 44 is fixedly installed on the outer side of the connecting plate 49, and the limit plate 44 is fixedly installed on the side of the side connecting plate 43 close to the bearing component 3.

[0024] The second embodiment is based on the first and second embodiments. Figures 4 to 5 As shown, the bearing assembly 3 includes a bottom plate 39 , a slide rail 35 is symmetrically arranged on the top of the bottom plate 39 , a slider 34 is slidably adapted inside the slide rail 35 , and a positioning frame 32 is fixedly installed on the top of the slider 34 .

[0025] The outer surface of the positioning frame 32 is fixedly installed with a clamping plate 37 on both sides. The surface of the clamping plate 37 close to the connecting plate 49 is provided with a square groove. The inside of the clamping plate 37 is slidably adapted with a guide plate 38 through the square groove. The guide plate 38 is fixedly connected to the connecting plate 49 via a screw rod on the side away from the clamping plate 37.

[0026] A connecting rod 36 is fixedly installed on the surface of the positioning frame 32 near the limiting plate 44, and a water spray pipe 31 is fixedly installed on the upper surface of the positioning frame 32. There are four water spray pipes 31, which are symmetrically arranged with the bottom plate 39 as the center, and a suction cup 33 is fixedly installed on the top of each water spray pipe 31. The staff pushes the slider 34 to slide in the slide rail 35 and drives the positioning frame 32 to move. A water spray pipe 31 is arranged on the top of the positioning frame 32, and the sprayed water is scattered in the suction cup 33 on the top. Since the plate is placed above the suction cup 33, the moisture between the plate and the suction cup 33 can improve the suction force of the suction cup 33. Since the plate of some trowel shells is set to be curved during production, the flexible suction cup 33 can fit tightly on the bottom surface of the plate according to the shape of the plate.

[0027] The third embodiment is based on the first and second embodiments. Figures 6 to 8 As shown, the position limiting assembly 2 includes a bottom block 25, two of which are symmetrically arranged on both sides of the outer surface of the bottom plate 39, and a support rod 21 is fixedly installed at the middle of the top of the bottom block 25. The slider 34 drives the positioning frame 32 to slide in the slide rail 35, and drives the clamping plate 37 to slide on the surface of the guide plate 38, thereby changing the position of the positioning frame 32 to adjust the grinding position of the plate, so that the irregular position of the plate surface is pre-processed by the position limiting assembly 2.

[0028] The top of the support rod 21 is fixedly mounted with a bending frame 24, the top of the bending frame 24 is fixedly mounted with a protective member 23, and the plate-attaching shaft 22 is fixedly mounted between the opposite surfaces of the protective member 23. The plate moves toward the plate-attaching shaft 22 along with the slider 34, and the protrusion of the irregular curved plate is squeezed with the protective member 23 when it contacts the protective member 23 and the plate-attaching shaft 22, and the plate is limited from above, so as to pre-fix the irregular surface of the plate.

[0029] The protective member 23 includes a sleeve plate 232, a shrinking sleeve 231 is fixedly installed inside the sleeve plate 232, a round rod 233 is fixedly installed at the axis of the shrinking sleeve 231, a round plate 234 is fixedly installed on the surface of the round rod 233 away from the shrinking sleeve 231, and the round plate 234 is fixedly installed inside the plate-attaching shaft 22. The curvature of the plate surface fits with the plate-attaching shaft 22 and the protective member 23, and the plate-attaching shaft 22 is set to be hollow and sleeved on the surface of the protective member 23, so as to fit with the plate to limit and fix the plate, and prevent the irregular plate from shifting during polishing.

[0030] The shrinking sleeve 231 includes a shaft pad 2311, a slot 2312 is provided inside the shaft pad 2311, an insert block 2313 is fixedly installed inside the slot 2312, a square block 2318 is sleeved on the outer surface of the insert block 2313, and a cylinder 2317 is fixedly installed on the surface of the square block 2318 away from the insert block 2313. The shrinking sleeve 231 has multiple openings on its surface and is sleeved on the surface of the plate-attaching shaft 22, so that the shrinking sleeve 231 changes its shrinking shape according to the curvature of the plate, and squeezes the inner support plate 2315 provided inside the shrinking sleeve 231, so that the spring 2314 between the inner support plate 2315 is squeezed and shrinks inwards and supported on the surface of the sleeve plate 232.

[0031] The cylinder 2317 is sleeved on the outer surface of the round rod 233, and the two sides of the block 2318 are provided with rotation grooves. A rotating seat 2316 is rotatably installed on the surface of the rotating groove. A spring 2314 is fixedly installed between the opposite surfaces of the rotating seat 2316, and an inner support plate 2315 is rotatably installed on the surface of the rotating seat 2316.

[0032] When in use, the staff places the plate on the supporting component 3, and sprays water into the suction cup 33 through the water spray pipe 31, so that the plate is adsorbed and fixed by the suction cup 33, and then the staff pushes the supporting component 3 to displace it toward the side of the polishing roller 1, so that the plate contacts the surface of the limiting component 2, and the limiting component 2 is fit and fixed to the surface of the plate. As the plate continues to displace toward the side of the polishing roller 1, the bottom of the plate and the suction cup 33 are scraped and gradually separated by the cross plate 41. The staff starts the motor 6 so that the output end of the motor 6 drives the polishing roller 1 to rotate, and the plate is polished, thereby improving the efficiency of plate processing and material taking.

[0033] The staff pushes the slider 34 to slide in the slide rail 35 and drives the positioning frame 32 to move. A water spray pipe 31 is set on the top of the positioning frame 32, and the sprayed water is scattered in the suction cup 33 on the top. Since the plate is placed above the suction cup 33, the moisture between the plate and the suction cup 33 increases the suction force of the suction cup 33. Since the plate of some trowel machine shells is set to be curved during production, the flexible suction cup 33 can fit tightly on the bottom surface of the plate according to the shape of the plate.

[0034] The slider 34 drives the positioning frame 32 to slide in the slide rail 35, and drives the clamping plate 37 to slide on the surface of the guide plate 38, thereby changing the position of the positioning frame 32 to adjust the grinding position of the plate, so as to pre-process the irregular position of the plate surface through the limit component 2.

[0035] As the slider 34 moves toward the plate-attaching shaft 22, the irregular curved plate's protrusions are squeezed against the protective member 23 and the plate-attaching shaft 22, and the plate is limited from above to pre-fix the irregular surface of the plate.

[0036] The curvature of the plate surface fits with the plate-sticking shaft 22 and the protective member 23. The plate-sticking shaft 22 is set to be hollow and sleeved on the surface of the protective member 23, so as to fit with the plate to limit and fix the plate, thereby preventing the irregular plate from deflecting during polishing.

[0037] The shrinking sleeve 231 is provided with a plurality of openings on its surface and is sleeved on the surface of the plate-sticking shaft 22, so that the shrinking sleeve 231 can change its shrinking shape according to the curvature of the plate and squeeze the inner support plate 2315 provided in the shrinking sleeve 231, so that the spring 2314 between the inner support plate 2315 is squeezed and shrinks inwardly and is supported on the surface of the sleeve plate 232.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
