[0002] Coating rollers are roller-shaped products made with a metal core and an outer polyurethane coating.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0049] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0050] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0051] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0052] As described in the background section, coating rollers are roller-shaped products made with a metal core and an outer polyurethane coating. As a core component of coating machines, the surface smoothness, levelness, surface scratches, and particulate impurities of coating rollers directly affect the surface quality of coated metal products. Therefore, when coating rollers exhibit decreased surface precision or defects, surface grinding is necessary.

[0053] Currently, the most common process involves using grinding devices such as grinders with abrasive belts or grinding wheels for polishing and grinding. The grinder includes a motor, mounting base, and electrical control system. Before use, the original machine tool's tool holder and other components must be removed to allow for the grinder's installation. After removing the tool holder, the grinder is mounted on the machine tool using its mounting base, and then the motor's power cable and the electrical control system's control cable are connected.

[0054] However, the grinding equipment has a complex structure, is bulky and heavy, and its overall installation and maintenance are cumbersome, affecting the overall efficiency of the coating roller grinding process. Furthermore, the high cost of using and maintaining consumables such as sanding belts or grinding wheels increases the overall cost of the coating roller grinding process.

[0055] Based on the above-mentioned technical problems, this application provides a rubber roller surface grinding device. In this technical solution, the rubber roller surface grinding device includes a machine tool, a connecting plate, and multiple grinding components. The machine tool has a tool holder, the connecting plate is connected to the tool holder, and the multiple grinding components are all connected to the connecting plate. Sandpaper is provided on the grinding components. The grinding components are configured to extend and retract relative to the connecting plate to apply pressure toward the coating rubber roller, so that the sandpaper is tightly against the surface of the coating rubber roller.

[0056] This solution involves directly adding a connecting plate and regrinding components to the existing machine tool's tool holder, eliminating the need for an additional large base or complex support structure, significantly reducing the installation complexity of the device and improving the efficiency of the regrinding process. Furthermore, the telescopic movement of the regrinding components relative to the connecting plate ensures that the sandpaper remains in close contact with the coating roller surface, compensating for gap changes caused by roller wear or deformation, and improving the regrinding effect.

[0057] It should be noted that, Figures 1 to 7 This diagram illustrates a simplified representation of the components in the rubber roller surface grinding device. The specific structures of the remaining components in the rubber roller surface grinding device are not limited to... Figures 1 to 7 of examples.

[0058] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, a rubber roller surface grinding device includes a machine tool 100, a connecting plate 200, and multiple grinding components 300.

[0060] Among them, combined Figure 1 and Figure 4 As shown, the machine tool 100 includes a base 110, a first support frame 120, a second support frame 130, a longitudinal feed mechanism 140, and a transverse feed mechanism 150. The first support frame 120 is connected to the base 110 via the longitudinal feed mechanism 140. The longitudinal feed mechanism 140 can drive the first support frame 120 to slide relative to the base 110. Here, the base 110 can be a guide rail, and the guide rail along... Figure 1 and Figure 4 It extends in the Y direction.

[0061] Unless otherwise specified, the directions indicated by the X, Y, and Z arrows in the figure are mutually perpendicular in three-dimensional space; the longitudinal feed mechanism 140 can drive the first support frame 120 to move along the length of the guide rail, that is, drive the first support frame 120 to slide along the direction indicated by the Y arrow.

[0062] The longitudinal feed mechanism 140 includes a motor (not shown in the figure), a first lead screw 141, and a slider 142. The slider 142 is connected to the first support frame 120 and is slidably connected to the guide rail. The output end of the motor is connected to the first lead screw 141 for transmission. The first support frame 120 is slidably connected to the first lead screw 141 through ball bearings. In specific implementation, the motor drives the first lead screw 141 to rotate, which in turn drives the first support frame 120 to slide along the extension direction of the first lead screw 141, so that the slider 142 moves relative to the guide rail.

[0063] The second support frame 130 is slidably connected to the second support frame 120 via a transverse feed mechanism 150. Specifically, the transverse feed mechanism 150 includes a second lead screw (not shown in the figure), a rotating wheel 151, and a slide rail 152. The slide rail 152 is connected to the first support frame 120, and a groove is provided on the second support frame 130. The slide rail 152 moves relative to the groove. The extension direction of the slide rail 152 is parallel to the direction of the X arrow, meaning that the second support frame 130 can slide relative to the first support frame 120 in the direction shown by the X arrow. The rotating wheel 151 is drivenly connected to the second lead screw, and the second support frame 130 is slidably connected to the second lead screw. In practice, rotating the rotating wheel 151 rotates the second lead screw, which in turn drives the second support frame 130 to slide along the slide rail 152.

[0064] The second support frame 130 has a tool holder 400, a connecting plate 200 connected to the tool holder 400, and multiple grinding components 300 connected to the connecting plate 200. Sandpaper 500 is provided on the grinding components 300. The grinding components 300 are configured to extend and retract relative to the connecting plate 200 to apply pressure toward the coating roller 10, so that the sandpaper 500 is tightly pressed against the surface of the coating roller 10.

[0065] Reference Figure 2 As shown, by setting a longitudinal feed mechanism 140 and a transverse feed mechanism 150, the longitudinal feed mechanism 140 can drive the grinding component 300 to move along the axial direction of the coating roller 10, which is suitable for coating rollers 10 with a large axial length; the transverse feed mechanism 150 can drive the grinding component 300 to move along the radial direction of the coating roller 10, which can change the distance between the grinding component 300 and the coating roller 10, and is suitable for coating rollers 10 with different diameters, improving adaptability. In addition, it can also finely adjust the distance between the grinding component 300 and the coating roller 10, which is suitable for fine grinding processes.

[0066] In the above embodiment, this solution directly adds the connecting plate 200 and the grinding assembly 300 to the existing machine tool 100's tool holder 400, eliminating the need for an additional large base or complex support structure, significantly reducing the installation complexity of the device. When grinding the coating roller 10, the roller 10 is rotated by a motor or other drive device. The longitudinal feed mechanism 140 and the transverse feed mechanism 150 work together to bring the sandpaper 500 into contact with the surface of the coating roller 10 for grinding, improving the efficiency of the grinding process. Furthermore, the telescopic movement of the grinding assembly 300 relative to the connecting plate 200 ensures that the sandpaper 500 remains in close contact with the surface of the coating roller 10, compensating for gap changes caused by wear or deformation of the coating roller 10 and improving the grinding effect.

[0067] The use and maintenance costs of 500 grit sandpaper are significantly lower than those of sanding belts or grinding wheels, which can reduce the cost of grinding processes.

[0068] In one possible implementation, combining Figure 5 As shown, the grinding assembly 300 includes a guide post 310, a mounting plate 320, and an elastic element 330.

[0069] The guide post 310 is connected to the connecting plate 200 and has a guide groove 311. The mounting plate 320 has a guide part 321, which is inserted into the guide groove 311. The mounting plate 320 fixes the sandpaper 500 through the fastener 322. The elastic member 330 is connected between the mounting plate 320 and the guide post 310 and is sleeved on the outer periphery of the guide part 321. When the sandpaper 500 comes into contact with the surface of the coating roller 10, the elastic member 330 always provides the mounting plate 320 with an elastic force away from the guide post 310.

[0070] In the above embodiment, the guide groove 311 on the guide post 310 provides strict motion trajectory constraints for the mounting plate 320, ensuring that the sandpaper 500 always applies pressure in a predetermined direction during the grinding process. This eliminates the risk of misalignment of the mounting plate 320, avoids localized deep scratches caused by skewed contact, and ensures the grinding consistency of multiple grinding components 300. It should be noted that when the grinding component 300 contacts the coating roller 10, due to the uncertainty of surface defects on the coating roller 10, the grinding component 300 may be subjected to reaction forces from different directions of the coating roller 10, which could cause the grinding component 300 to misalign and affect the grinding effect. By setting the guide groove 311, the motion trajectory of the mounting plate 320 is clearly defined, eliminating reaction forces from different directions of the coating roller 10 and preventing misalignment of the mounting plate 320.

[0071] The elastic element 330 is sleeved around the guide portion 321. When the sandpaper 500 abuts against the coating roller 10, it continuously applies a spring force away from the guide post 310, enabling the mounting plate 320 to have self-adjusting capability. It can be understood that the elastic element 330 can be a spring, which remains compressed when the sandpaper 500 abuts against the coating roller 10. This automatically compensates for gap changes caused by slight deformation or vibration of the coating roller 10, maintaining the grinding contact pressure between the sandpaper 500 and the coating roller 10.

[0072] In addition, the guide part 321 of the mounting plate 320 can be directly inserted into the guide groove 311 without complicated alignment operations, which shortens the installation time and allows ordinary workers to complete the replacement of the grinding component 300; it also facilitates the periodic inspection or replacement of worn elastic parts 330.

[0073] In one possible implementation, to ensure that the guide portion 321 does not disengage from the guide groove 311, the length of the guide portion 321 and the extension length of the spring can be adaptively designed. For example, even when the spring is at its longest, a portion of the guide portion 321 can still be kept inside the guide groove 311. Alternatively, both ends of the spring can be connected to the mounting plate 320 and the guide post 310, respectively. For example, the end of the spring near the guide post 310 can be connected to the guide post 310, and the end of the spring near the mounting plate 320 can be connected to the mounting plate 320. Through the connection of the spring to the mounting plate 320 and the guide post 310, combined with the length design of the guide portion 321, it can be ensured that the guide portion 321 does not disengage from the guide groove 311.

[0074] In practice, both the spring guide post 310 and the mounting plate 320 can be detachably connected. For example, the guide post 310 and the mounting plate 320 are provided with connection holes, and the two ends of the spring are hooked into the two connection holes respectively, so as to facilitate the disassembly and replacement of the spring.

[0075] The length of the guide groove 311 or guide section 321 can be designed as needed to further adapt to coating rollers 10 with different diameters.

[0076] Reference Figure 3 and Figure 5 As shown, in one possible implementation, the mounting plate 320 includes a connecting surface 323 and an arcuate convex surface 324.

[0077] The connecting surface 323 is provided with a guide part 321 and a fixing part 322. The arc-shaped convex surface 324 protrudes away from the guide post 310 and abuts against the sandpaper 500.

[0078] The guide portion 321 can be a columnar body, and the guide groove 311 can be a circular hole adapted to the guide portion 321.

[0079] The arc-shaped convex surface 324 of the mounting plate 320 contacts the arc surface of the outer diameter of the coating roller 10, enabling the sandpaper 500 to achieve large-area line contact rather than point contact along the generatrix of the coating roller 10. This significantly improves the grinding efficiency per unit time. When the coating roller 10 has slight bending or ellipticity errors, the geometric characteristics of the arc-shaped convex surface 324 allow the mounting plate 320 to automatically adjust the contact angle within a certain range according to the actual contour of the coating roller 10, thus being compatible with the grinding needs of non-standard rollers.

[0080] Here, the fastener 322 can be a screw. Fasteners 322 are provided on both the upper and lower parts of the same mounting plate 320. The screw on the upper part fixes one end of the sandpaper 500, and the screw on the lower part fixes the other end of the sandpaper 500. The sandpaper 500 can cover the arc-shaped convex surface 324.

[0081] For details, please refer to... Figure 3 As shown, the screw is located on the connecting surface 323 to avoid the coating roller 10 and prevent interference with the coating roller 10.

[0082] Alternatively, it can be understood that the mounting plate 320 is a semi-cylinder, with the arc surface of the semi-cylinder abutting against the sandpaper 500 and protruding away from the guide post 310.

[0083] In one possible implementation, refer to Figure 5 and Figure 6 As shown, and in combination Figure 1 and Figure 2 The mounting plate 320 extends axially along the coating roller 10, and multiple mounting plates 320 are arranged radially spaced along the coating roller 10. The length direction of the mounting plate 320 is parallel to the axial direction of the coating roller 10. A single mounting plate 320 extends axially along the coating roller 10. Combined with the control of the longitudinal feed mechanism 140, the mounting plate 320 can cover the entire length of the coating roller 10, which is especially suitable for continuous grinding of long coating rollers 10.

[0084] Multiple mounting plates 320 are arranged radially spaced along the coating roller 10, for example... Figure 2 The vertically spaced arrangement creates multiple grinding points, improving grinding efficiency.

[0085] Reference Figures 5 to 8 As shown, Figure 5 The image shows the first implementation of the grinding component 300. Figure 6 The image shows a second implementation of the grinding component 300. Figure 7 The image shows a third implementation of the grinding component 300. Figure 8 The fourth implementation of the grinding component 300 is shown.

[0086] In one possible implementation, refer to Figure 6 As shown, combined with Figures 1 to 3 Multiple guide posts 310 are provided, and the multiple guide posts 310 are arranged at intervals along the extension direction of the mounting plate 320. Multiple guide parts 321 and multiple elastic elements 330 are provided, and the multiple guide parts 321, multiple guide posts 310 and multiple elastic elements 330 are all provided in a one-to-one correspondence.

[0087] It should be noted here that you should continue to refer to... Figure 5 and Figure 6 As shown, it can be as follows Figure 5 A guide post 310 is connected to a mounting plate 320, or it can be as follows: Figure 6 As shown, a mounting plate 320 is connected to a plurality of guide posts 310. This application embodiment describes a mounting plate 320 connected to a plurality of guide posts 310.

[0088] In the above embodiment, a plurality of guide portions 321 are provided on a single mounting plate 320. Each guide portion 321 is inserted into the guide groove 311 of the corresponding guide post 310, providing multiple limiting points for the movement of the mounting plate 320 and improving the stability of the mounting plate 320 relative to the connecting plate 200 during telescoping.

[0089] Multiple guide posts 310 are arranged at intervals along the extension direction of the mounting plate 320, significantly improving the bending and torsional stiffness of the mounting plate 320. Compared with the single guide post 310 scheme of the first implementation, it can effectively suppress the vibration or displacement of the mounting plate 320 caused by the grinding reaction force, which is especially suitable for high-speed rotation conditions and ensures stable contact between the sandpaper 500 and the coating roller 10. Through redundant design, even if one guide post 310 fails or is damaged, the remaining guide posts 310 can still maintain basic functions, avoiding the failure of the entire grinding assembly 300.

[0090] In one possible implementation, the connecting plate 200 is provided with a mounting part 201, the mounting part 201 is provided with a positioning hole 202, the tool holder 400 is provided with a mounting groove 401, and the mounting part 201 is inserted into the mounting groove 401.

[0091] The tool holder 400 is equipped with a clamping bolt 600, which passes through the threaded hole of the tool holder 400 and is inserted into the positioning hole 202.

[0092] In the above embodiment, the mounting portion 201 of the connecting plate 200 is directly inserted into the mounting slot 401 of the tool holder 400, eliminating the need for complex alignment operations. Combined with the positioning hole 202, the position of the connecting plate 200 can be quickly locked. The clamping bolt 600 passes through the threaded hole of the tool holder 400 and is embedded in the positioning hole 202, forming a self-locking structure. Tightening / loosening operations can be completed with one hand, simplifying the structure, streamlining the operation process, and improving operational efficiency. Disassembly only requires loosening the clamping bolt 600 to release the fixation, facilitating regular maintenance or replacement of the sandpaper 500.

[0093] In one possible implementation, multiple positioning holes 202 are provided, and the multiple positioning holes 202 are arranged at intervals along the length direction of the mounting part 201. The clamping bolt 600 can be inserted into one of the positioning holes 202 through the threaded hole.

[0094] In the above embodiment, by providing multiple spaced positioning holes 202, the user can select the most suitable positioning point for fixing according to the actual length of the coating roller 10 or the grinding requirements. The clamping bolt 600 can be inserted into one of the positioning holes 202 through a threaded hole. By adjusting the different positioning holes 202 into which the clamping bolt 600 is inserted, the axial position of the connecting plate 200 (and the grinding assembly 300) can be precisely controlled to adapt to the grinding requirements of coating rollers 10 of different specifications.

[0095] In one possible implementation, refer to Figure 7 As shown, the grinding assembly 300 includes: a guide post 310 connected to the connecting plate 200, the guide post 310 having a guide groove 311; a mounting hemisphere 340 having a guide portion 321 inserted into the guide groove 311, the mounting hemisphere 340 fixing the sandpaper 500 by a fixing member 322; and an elastic member 330 connected between the mounting hemisphere 340 and the guide post 310, the elastic member 330 being sleeved on the outer periphery of the guide portion 321, the elastic member 330 always providing the mounting plate 320 with an elastic force away from the guide post 310 when the sandpaper 500 abuts against the surface of the coating roller 10.

[0096] The guide groove 311 on the guide post 310 provides strict movement trajectory constraints for the mounting plate 320, ensuring that the sandpaper 500 always applies pressure in a predetermined direction during the grinding process. An elastic element 330 is sleeved around the guide portion 321. When the sandpaper 500 abuts against the coating roller 10, it continuously applies a spring force away from the guide post 310. This elastic element 330 can be understood as a spring, which remains compressed when the sandpaper 500 abuts against the coating roller 10. This automatically compensates for gap changes caused by slight deformation or vibration of the coating roller 10, maintaining the grinding contact pressure between the sandpaper 500 and the coating roller 10.

[0097] In the above embodiment, the hemispherical surface 341 of the mounting hemisphere 340 abuts against the sandpaper 500, forming a natural multi-directional adhesion capability. The hemispherical surface 341 can simultaneously accommodate radial runout, axial offset, and minor taper errors of the coating roller 10, ensuring that the sandpaper 500 and the surface of the coating roller 10 always remain in contact. The continuous elastic force provided by the elastic element 330 enables the mounting hemisphere 340 to have self-adjusting capabilities, automatically filling gap fluctuations caused by wear or deformation of the coating roller 10.

[0098] In one possible implementation, mounting hemisphere 340 includes a connecting surface 323 and a hemisphere 341.

[0099] A guide portion 321 and a fixing member 322 are provided on the connecting surface 323. The hemispherical surface 341 protrudes away from the guide post 310 and abuts against the sandpaper 500. It should be noted that each mounting hemisphere 340 is provided with sandpaper 500, forming multiple points of contact with the coating roller 10. The hemispherical surface 341 of the mounting hemisphere 340 abuts against the arc-shaped surface of the coating roller 10 through the sandpaper 500, which can accommodate coating rollers 10 of various specifications and improve compatibility.

[0100] In one possible implementation, refer to Figure 8 As shown, combined with Figure 2 Multiple grinding components 300 are arranged radially at intervals along the coating roller 10. Sandpaper 500 covers multiple grinding components 300. One grinding component 300 at one end fixes one end of the sandpaper 500, and the other grinding component 300 at the other end fixes the other end of the sandpaper 500.

[0101] In this way, by setting up a sandpaper 500 to cover multiple grinding components 300, and fixing both ends of the sandpaper 500 to the end grinding components, while ensuring that the sandpaper 500 between the two end grinding components 300 has a certain deformation allowance, when grinding the coating roller 10, the transverse feeding mechanism 150 brings the multiple grinding components 300 close to the coating roller 10 simultaneously. Under the elastic force of the elastic element 330, the sandpaper 500 comes into close contact with the surface of the coating roller 10, and at this time, multiple points of contact are formed between each grinding component 300 and the coating roller 10, so that the sandpaper 500 grinds the coating roller 10. Through the above arrangement, the sandpaper 500 replacement process can be simplified, the maintenance efficiency of the device can be improved, and thus the grinding efficiency of the coating roller 10 can be improved.

[0102] The implementation principle of the rubber roller surface grinding device in this application embodiment is as follows: The rubber roller surface grinding device includes a machine tool 100, a connecting plate 200, and multiple grinding components 300. The machine tool 100 has a tool holder 400, the connecting plate 200 is connected to the tool holder 400, and the multiple grinding components 300 are all connected to the connecting plate 200. Sandpaper 500 is provided on the grinding components 300. The grinding components 300 are configured to extend and retract relative to the connecting plate 200 to apply pressure toward the coating rubber roller 10, so that the sandpaper 500 tightly abuts against the surface of the coating rubber roller 10. This solution directly adds the connecting plate 200 and grinding components 300 to the existing tool holder 400 of the machine tool 100, without the need for an additional large base or complex support structure, significantly reducing the installation complexity of the device and improving the efficiency of the grinding process.

[0103] In addition, the telescopic movement of the grinding component relative to the connecting plate ensures that the sandpaper always adheres tightly to the surface of the coating roller, compensating for gap changes caused by wear or deformation of the coating roller and improving the grinding effect.
