[0012] Compared with the prior art, this utility model provides a grinding device for hot roller processing, which has the following beneficial effects:

[0013] 1. This grinding device for hot roller processing uses an immersion grinding method to ensure that the debris generated during grinding is promptly washed away by the water flow to prevent it from remaining on the grinding contact surface. At the same time, the debris is driven by the grinding belt to approach the inner wall of the grinding water tank, and then moves downward over the lower barb partition to the bottom of the separator filter plate. The separator filter plate, the upper barb partition, and the lower barb partition work together to collect the debris, preventing the debris from mixing in the water and moving back to the surface of the hot roller, thus affecting the grinding efficiency.

[0014] 2. The grinding device for hot roller processing first preheats the hot roller and simultaneously heats the water inside the grinding tank through a heating plate, creating a relatively high-temperature grinding environment. During grinding, the grinding belt directly contacts the outer surface of the hot roller across its entire width, gradually grinding small areas to reduce deformation of the hot roller surface caused by grinding. Furthermore, during the grinding process, water is used to uniformly heat the hot roller, rapidly cooling the grinding area while maintaining the temperature of non-grinding areas. This reduces deformation caused by temperature differences, ensuring uniform contact between the grinding belt and the hot roller surface and improving the grinding quality.

[0015] 3. This grinding device for hot roller processing can clamp hot rollers of different diameters and lengths by adjusting the distance between the two telescopic clamping seats. Furthermore, by adjusting the distance between the rear support shaft and the front drive shaft, it can grind hot rollers of different diameters. By adjusting the position of the rear support shaft, the length of the grinding belt extending into the grinding water tank can be adjusted, ensuring that the grinding belt remains in contact with the surface of the hot roller. This device is suitable for grinding hot rollers of different sizes, thus improving its applicability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a grinding device for hot roller processing, including a grinding water tank 1, a clamping device 3 for clamping and fixing the ends of hot rollers of different sizes, and a grinding device 5 for grinding hot rollers of different sizes. The bottom of the grinding water tank 1 is equipped with a support bracket 2 for support. The left side wall of the grinding water tank 1 is equipped with a water injection pipe 8 for adding water to the inside. The bottom of the grinding water tank 1 is equipped with a drain pipe 7 for discharging sewage. The top of the grinding water tank 1 is equipped with the grinding device 5 for grinding hot rollers of different sizes. The inner wall of the grinding water tank 1 is equipped with a clamping device 3 for clamping and fixing the ends of hot rollers.

[0023] Furthermore, a heating plate 9 is installed on the inner wall of the grinding water tank 1 for heating. The heating plate 9 heats the water inside the grinding water tank 1. During the grinding process, the hot water heats the non-grinding area of ​​the hot roller and cools the grinding area with higher temperature, thereby reducing the temperature difference on the surface of the hot roller and reducing the deformation of the hot roller.

[0024] Furthermore, a separator filter plate 6 for separating filter cake is installed on the inner wall of the grinding tank 1 near the bottom. The end of the separator filter plate 6 is provided with an upper barbed baffle 61 to prevent the filter cake from moving outward along the separator filter plate 6. The bottom inner wall of the grinding tank 1, located below the separator filter plate 6, is provided with a lower barbed baffle 62 to prevent the filter cake from moving outward along the bottom of the separator filter plate 6. The debris moving downward along the inner wall of the grinding tank 1 can cross the upper barbed baffle 61 and enter below the separator filter plate 6. Through the cooperation of the separator filter plate 6, the upper barbed baffle 61 and the lower barbed baffle 62, a V-shaped opening is formed at the bottom of the grinding tank 1, making it difficult for the debris entering below the separator filter plate 6 to be discharged with the water flow. This allows the debris to be stored and filtered as much as possible below the separator filter plate 6, reducing the number of suspended debris in the water.

[0025] Furthermore, the grinding device 5 includes a front support plate 51, a positioning support shaft 52, a front support frame 53, a grinding motor 54, a front drive shaft 55, a rear support plate 56, a sliding support seat 57, an adjusting and moving motor 58, and a rear support shaft frame 59. The front support plate 51 is installed on the top of the grinding water tank 1, the front support frame 53 is installed on the top of the front support plate 51, the grinding motor 54 is installed on the left side wall of the front support frame 53, and the front drive shaft 55 is rotatably installed on the right side wall of the front support frame 53 via a bearing. The surface of the front drive shaft 55 is provided with anti-slip texture to improve the rotation of the front drive shaft 55. To ensure the stability of the grinding belt drive and prevent slippage, the output end of the grinding motor 54 passes through the front support frame 53 and is installed at the end of the front drive shaft 55. The rear support plate 56 is installed on the rear side of the top of the grinding water tank 1. The sliding support seat 57 is slidably engaged with the top of the rear support plate 56 in the front-back direction. The adjusting moving motor 58, used to control the front-back movement of the sliding support seat 57, is installed on the rear side wall of the rear support plate 56. A screw is installed on the output end of the adjusting moving motor 58, and the front end of the screw is threadedly connected to the bottom of the sliding support seat 57. The support bracket 59 is rotatably mounted to the sliding support seat 57 via bearings. A grinding belt is sleeved on the outer side of the front drive shaft 55 and the rear support bracket 59. The top of the front support plate 51 and the rear support plate 56 are both provided with inclined grooves. A positioning support shaft 52 for supporting and separating the upper and lower layers of the grinding belt is installed inside the inclined groove. The positioning support shaft 52 separates the upper and lower layers of the grinding belt to prevent contact and friction when the upper and lower layers of the grinding belt move in different directions during grinding. The inner wall of the grinding water tank 1 is located near the bottom and is rotated by bearings. The bottom support roller is equipped to support the bottom belt. The grinding belt that is not grinding at the bottom is separated from the grinding belt that is grinding at the top under the support of the bottom support roller, so as to prevent the two from rubbing against each other during grinding and affecting the quality. During installation, the grinding belt is sleeved on the outside of the front drive shaft 55 and the rear support shaft frame 59. The positioning support shaft 52 is composed of two support rollers. The lower side of the grinding belt passes through the middle of the two support rollers and the lower side of the grinding belt passes through the middle of the bottom support roller. The upper side surface of the grinding belt is in contact with the surface of the hot roller.

[0026] Furthermore, the clamping device 3 includes an angle adjustment seat 31, a telescopic clamping seat 32, an adjusting threaded ring 33, a clamping opening 34, an auxiliary support plate 35, and a rotating handle 36. The angle adjustment seat 31 is rotatably mounted to the left side wall of the grinding water tank 1 via a bearing. An angle adjusting motor 4 for controlling the rotation angle of the angle adjustment seat 31 is mounted on the left side wall of the grinding water tank 1 via a bracket. The output end of the angle adjusting motor 4 is mounted to the left side wall of the angle adjustment seat 31. The right end of the angle adjustment seat 31 extends into the grinding water tank 1. A direction insertion rod is provided on the left side wall of the telescopic clamping seat 32. The telescopic clamping seat 32 is movably inserted into the right side wall of the angle adjustment seat 31. The left end of the adjusting threaded ring 33 is rotatably mounted to the right side wall of the angle adjustment seat 31 via a bearing. A threaded ring is provided on the inner wall of the adjusting threaded ring 33 and threadedly connected to the outer wall of the telescopic clamping seat 32. The rotating handle 36 for controlling the rotation of the adjusting threaded ring 33 is connected to the adjusting threaded ring 36. A clamping opening 34 for pressing and fixing the end of the hot roller is installed on the outer wall of the ring 33. It is located on the right side wall of the telescopic clamping seat 32. An auxiliary support plate 35 for auxiliary support and positioning during the installation of the hot roller is installed on the right side wall of the telescopic clamping seat 32 and below the clamping opening 34. During installation, the end of the hot roller is placed on the auxiliary support plate 35, and then the rotating handle 36 is turned. The rotating handle 36 drives the adjusting thread ring 33 to rotate. The adjusting thread ring 33 drives the telescopic clamping seat 32 to move inward through the thread. The telescopic clamping seat 32 clamps and fixes the end of the hot roller through the clamping opening 34. After fixing, when it is necessary to adjust the grinding area during the grinding process, the angle adjusting motor 4 drives the angle adjusting seat 31 to rotate for adjustment. After the grinding is completed, the auxiliary support plate 35 is rotated to the lowest position to reset, which is convenient for the next grinding and installation work.

[0027] Furthermore, the clamping opening 34 has a trumpet-shaped opening. By squeezing the left and right clamping openings 34 towards the center, the end of the circular hot roller can be pushed and squeezed towards the axial position, thereby achieving the positioning function while squeezing and fixing. The end of the hot roller is chamfered to reduce the contact friction force when the clamping opening 34 is squeezing and fixing.

[0028] In use, water is added to the grinding water tank 1 through the water injection pipe 8, and the water is preheated by the heating plate 9. Then, the preheated roller end is placed above the auxiliary support plate 35 using the hoisting equipment. Then, the adjusting threaded ring 33 is rotated by turning the handle 36, which drives the telescopic clamping seat 32 to move inward. The telescopic clamping seat 32 drives the clamping opening 34 to move inward, and the telescopic clamping seat 32 squeezes the roller end into the clamping opening 34. By squeezing from both ends simultaneously, the roller end gradually comes into complete contact with the inner wall of the clamping opening 34. The clamping openings 34 on both sides then squeeze and fix the end. Then, the adjusting moving motor 58 is started, which drives the sliding support seat 57 to move backward. The sliding support seat 57 drives the rear support shaft 59 to move backward, and the rear support shaft 59 tightens the outer sleeve of the grinding belt, making the grinding belt more secure. The grinding belt contacts the surface of the roller material, and then the grinding motor 54 is started. The grinding motor 54 drives the front drive shaft 55 to rotate, and the front drive shaft 55 drives the grinding belt to rotate. The grinding belt grinds the surface of the roller material. During the grinding process, heated water is used to keep the hot roller warm and to cool the grinding area. At the same time, the grinding debris is cleaned up. The debris is moved by the grinding belt and water to a position close to the inner wall of the grinding water tank 1, and then slides down the inner wall of the grinding water tank 1. Finally, it slides to the bottom of the separator filter plate 6 for temporary storage to prevent the grinding debris from floating up and down in the flowing water cavity. After the bottom area is ground, the angle adjustment motor 4 drives the clamping device 3 to rotate. The clamping device 3 drives the material roller to deflect, thereby grinding different areas. After grinding is completed, the handle 36 is rotated in the opposite direction to release the fixing of the material roller, and then the material roller is lifted out by the hoisting equipment.
