[0049] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0051] Please refer to Figure 1-Figure 4 , Figure 1 A schematic structural diagram of a roller polishing device 100 provided in this embodiment at a first viewing angle; Figure 2 A schematic structural diagram of the roll polishing device 100 provided in this embodiment at a second viewing angle; Figure 3 A schematic structural diagram of the roller polishing device 100 provided in this embodiment at a third viewing angle; Figure 4 This is a schematic structural diagram of the frame 110, the roller 120 and the limiter 240 provided in this embodiment.

[0052] The present invention provides a roller polishing device 100, which includes a frame 110, a roller 120, a support seat 130 and an elastic member 150; the roller 120 is rotatably connected to the frame 110; the support seat 130 is movably connected to the frame 110, and the support seat 130 moves along the axial direction of the roller 120; the two ends of the polisher 140 respectively form a polishing end 141 and a mounting end 142; the polishing end 141 acts on the roller 120, and the mounting end 142 is movably connected to the support seat 130.

[0053] It can be understood that the polishing end 141 of the polisher 140 acts on the roller 120, and the polishing end 141 is in point contact with the surface of the roller 120. However, since the support seat 130 can drive the polisher 140 to move along the axial direction of the roller 120, and the roller 120 rotates around its axis, the contact position between the polishing end 141 and the surface of the roller 120 is constantly changing, so that the polisher 140 can polish the circumferential surface of the roller 120 to change the roughness of the circumferential surface of the roller 120.

[0054] It should be noted that the polisher 140 can not only make the surface of the roller 120 smoother, but also make the surface of the roller 120 rougher, thereby increasing the friction coefficient of the surface of the roller 120, so that the roller 120 can prevent the material from falling off the roller 120 when transporting the material.

[0055] Please refer to Figure 4 The roller 120 is provided with a plurality of annular grooves 121 arranged at intervals along its axial direction. Therefore, the depth of the peripheral surface of the roller 120 in the axial direction of the roller 120 is avoided. Therefore, the present embodiment also includes an elastic member 150, one end of the elastic member 150 is connected to the support seat 130, and the other end of the elastic member 150 is connected to the polisher 140; the elastic member 150 is used to make the polishing end 141 have a tendency to move toward the roller 120.

[0056] When the support seat 130 drives the polisher 140 to move from the notch of the annular groove 121 to the bottom of the annular groove 121, the polisher 140 approaches the roller 120 under the action of the elastic force of the elastic member 150, so that the polishing end 141 can abut against the groove wall of the annular groove 121, thereby polishing the groove wall of the annular groove 121; it can be understood that at this time, the elastic member 150 gradually extends.

[0057] When the support seat 130 drives the polisher 140 to move from the bottom of the annular groove 121 to the groove mouth of the annular groove 121, the position of the roller 120 will not change. Therefore, the polisher 140 will overcome the elastic force and move away from the roller 120, so that the polishing end 141 abuts against the groove wall of the annular groove 121 to polish the circumferential surface of the roller 120; it can be understood that at this time, the elastic member 150 gradually shrinks.

[0058] It should be noted that, during the process of the polishing end 141 acting on the roller 120, the elastic member 150 is always in a compressed state, so that the polisher 140 can always be subjected to the elastic force from the elastic member 150, so that the polisher 140 can be pressed against the roller 120, and then the roller 120 can be polished. If the elastic member 150 is in a free state, there is an interaction force between the polishing end 141 and the roller 120, and the roller 120 cannot be polished; if the elastic member 150 is in a stretched state, the polishing end 141 will gradually move away from the roller 120 under the action of the elastic member 150.

[0059] Therefore, the polisher 140 of this embodiment can be driven by the support seat 130 and can utilize the adaptability of the elastic member 150 to automatically polish the roller 120 with different surface depths to change the surface roughness of the roller 120, thereby increasing the friction coefficient of the roller 120 and improving the polishing efficiency and polishing effect.

[0060] In this embodiment, the elastic member 150 is a spring, and in other embodiments, other elastic structures may be used. In addition, in this embodiment, the elastic member 150 is extended and contracted in a direction perpendicular to the axis of the roller 120 , so that the elastic member 150 can drive the polishing end 141 to move closer to or away from the roller 120 .

[0061] For further information, please refer to Figure 1 The present embodiment further includes a support rod 160, the support seat 130 is connected to the support rod 160, and at least a portion of the elastic member 150 is sleeved on the support rod 160. Specifically, the axial direction of the support rod 160 is parallel to the expansion and contraction direction of the elastic member 150, thereby preventing the elastic member 150 from moving in other directions, preventing the polishing end 141 of the polisher 140 from being unable to act on the roller 120, and thus affecting the polishing efficiency and polishing effect.

[0062] According to the above structural arrangement, the present embodiment further includes a first detector 170 , a second detector 210 , a telescopic rod 180 and a controller 190 ; the controller 190 is electrically connected to the first detector 170 and the telescopic rod 180 .

[0063] The first detector 170 is arranged at one end of the support rod 160 connected to the elastic member 150. The first detector 170 is used to detect the telescopic state of the elastic member 150 and to send a telescopic signal to the controller 190. The second detector 210 is arranged on the frame 110 and is electrically connected to the controller 190. The second detector 210 is used to detect the curvature change of the circumference of the roller 120 along the axis direction of the roller 120 and to send a curvature signal to the controller 190. The controller 190 is arranged on the support rod 160 and is used to receive the telescopic signal and the curvature signal. The fixed end 182 of the telescopic rod 180 is connected to the support rod 160, and the movable end 181 of the telescopic rod 180 acts on the polishing end 141 of the polisher 140. The controller 190 drives the movable end 181 based on the telescopic signal and the curvature signal, so that the movable end 181 drives the polishing end 141 to approach or move away from the roller 120.

[0064] Specifically, the elastic member 150 in this embodiment is a spring. When the pitch of the spring reaches the minimum value, the spring cannot be compressed. However, at this time, a greater force may be required to act on the roller 120 to achieve the desired polishing effect. Therefore, the telescopic rod 180 is provided in this embodiment to compensate for the pressure acting on the polisher 140. The first detector 170 is used to detect the pitch of the spring. When the first detector 170 detects that the pitch of the spring reaches the minimum value, a telescopic signal about the spring is generated and the telescopic signal is sent to the controller 190.

[0065] The second detector 210 can emit ultrasound or light to the roller 120, and the roller 120 reflects the ultrasound or light. The second detector 210 obtains the groove depth of the annular groove 121 in the roller 120 by the time required for generating and receiving the ultrasound or light, thereby forming an arc signal about the roller 120 and sending it to the controller 190.

[0066] In other embodiments, the depth of the annular groove 121 of the roller 120 may be detected by other methods to detect the depth change of the surface of the roller 120 .

[0067] After receiving the telescopic signal and the radian signal about the roller 120, the controller 190 controls the contraction or extension of the telescopic rod 180 according to the telescopic signal and the radian signal, so that the movable rod of the telescopic rod 180 approaches or moves away from the roller 120, so that there is sufficient interaction force between the polisher 140 and the roller 120, so that the polisher 140 can polish the roller 120, thereby improving the polishing effect.

[0068] It should be noted that, in the present embodiment, the controller 190 is a servo motor 234 . In other embodiments, the controller 190 may also be other devices.

[0069] The second detector 210 can detect data such as the cross-sectional size, diameter, and rotation speed of different types of rollers 120, as shown in Table 1, Table 2, and Table 3, where H in the table is a horizontal rolling mill and V is a vertical rolling mill. The second detector 210 transmits the detected data to the controller 190, and the controller 190 controls the contraction or extension of the telescopic rod 180 to approach or stay away from the roller 120.

[0078] For further information, please refer to Figure 1-Figure 3This embodiment also includes a column 220, one end of which is connected to the support rod 160; the column 220 is provided with at least one mounting hole 221; the support seat 130 is provided with at least one adjustment hole 131; the roller polishing device 100 also includes at least one connecting member (not shown); the connecting member is movably matched with one of the mounting hole 221 and the adjustment hole 131, and fixedly matched with the other, and the column 220 and the support seat 130 are movably connected through the connecting member.

[0079] Specifically, one end of the column 220 is connected to the support seat 130, and the other end of the column 220 is provided with a through hole, and one end of the support rod 160 passes through the through hole and is connected to the elastic member 150. In this embodiment, the support rod 160 and the column 220 are connected by bolts. In other embodiments, other connection methods can also be selected according to actual conditions.

[0080] It should be noted that in this embodiment, there are multiple rollers 120, which are arranged at intervals on the frame 110, and the axes of the multiple rollers 120 are parallel. The arrangement direction of the multiple rollers 120, the axis direction of the rollers 120, and the expansion and contraction direction of the elastic member 150 are perpendicular to each other.

[0081] After polishing of one roller 120 is completed, another roller 120 needs to be polished, and the movable cooperation of the connecting piece and the adjustment hole 131 is utilized to drive the column 220 to move, wherein the moving direction of the column 220 is parallel to the arrangement direction of the multiple rollers 120, so that the column 220 can drive the polishing end 141 of the polisher 140 to move from one roller 120 to another roller 120, thereby realizing the polishing of multiple rollers 120 and improving the polishing efficiency.

[0082] Since the moving direction of the column 220 is parallel to the arrangement direction of the plurality of rollers 120 , the moving direction of the column 220 , the expansion and contraction direction of the elastic member 150 , and the axial direction of the rollers 120 are perpendicular to each other.

[0083] According to the above content, the adjustment hole 131 in this embodiment is an arc hole 1311, and the number of the arc holes 1311 is two, and the two arc holes 1311 are arranged at intervals along the axis direction perpendicular to the roller 120, and the centers of the circles coincide. It can be understood that the two arc holes 1311 are arranged at intervals along the arrangement direction of the multiple rollers 120, so when the connecting member and the arc holes 1311 are movably matched to drive the column 220 to move, the column 220 will move along the arrangement direction of the multiple rollers 120, so as to move the polishing end 141 of the polisher 140 from one roller 120 to another roller 120, thereby achieving polishing of the multiple rollers 120.

[0084] In other embodiments, the adjustment hole 131 may also be an elongated hole, and the extension direction of the elongated hole is parallel to the arrangement direction of the plurality of rollers 120 . Different adjustment holes 131 may be selected according to actual conditions to adjust the movement of the column 220 .

[0085] For further information, please refer to Figure 1-Figure 3 In this embodiment, the roller polishing device 100 further includes a moving assembly 230, which includes a base 231, a guide rod 232, a motor 234 and a coupling 235. The guide rod 232 is disposed on the base 231. The support seat 130 in this embodiment is provided with a through hole 132, which is slidably matched with the guide rod 232. The motor 234 is connected to the guide rod 232 through the coupling 235, so that the motor 234 can drive the guide rod 232 to rotate. It can be understood that the guide rod 232 in this embodiment is a screw rod. Therefore, when the guide rod 232 rotates, the support seat 130 can move relative to the guide rod 232 along the axial direction of the guide rod 232.

[0086] In this embodiment, the axial direction of the guide rod 232 is parallel to the axial direction of the roller 120 , so that the support seat 130 can move along the axial direction of the roller 120 .

[0087] It should be noted that the support seat 130 in this embodiment includes an adjusting portion 133 and a moving portion 134 , the adjusting portion 133 and the moving portion 134 are connected, the arc hole 1311 is arranged on the adjusting portion 133 , and the through hole 132 is arranged on the moving portion 134 , and the moving portion 134 is slidably matched with the guide rod 232 .

[0088] According to the above, in this embodiment, the moving assembly 230 further includes two sensors 233 . The two sensors 233 are spaced apart from each other on the base 231 , and the distance between the two sensors 233 is equal to the length of the roller 120 in the axial direction thereof.

[0089] When the support base 130 contacts an inductor 233 during the movement, the inductor 233 sends a contact signal to the motor 234. After receiving the contact signal, the motor 234 drives the wire rod to rotate in the opposite direction, so that the support base 130 moves in the opposite direction, and then the support base 130 gradually approaches the other inductor 233. As a result, the support base 130 can reciprocate between the two inductors 233, so that the polisher 140 can reciprocate along the axis direction of the roller 120, so that the roller 120 is polished multiple times to improve the polishing effect.

[0090] For further information, please refer to Figure 1-Figure 4In this embodiment, the roller polishing device 100 also includes a limit member 240, and the roller 120 is located between the limit member 240 and the polisher 140. In this embodiment, the limit member 240 is set to limit the movement of the roller 120 in a direction perpendicular to the axis of the polisher 140 under the action of the polisher 140, so as to avoid the position of the roller 120 from changing, thereby affecting the polishing efficiency and polishing effect.

[0091] Please refer to Figure 1-Figure 5 , Figure 5 The present embodiment also includes a dustproof member 250, which includes a shielding portion 251 and a clamping portion 252, wherein the clamping portion 252 is connected to the frame 110, the shielding portion 251 is engaged with the clamping portion 252, and the shielding portion 251 extends along the axis direction of the roller 120, thereby shielding the debris generated during the polishing process to prevent the debris from causing harm to the staff.

[0092] In summary, the present embodiment provides the elastic member 150 so that the polisher 140 can move toward the roller 120 under the elastic action of the elastic member 150, and can abut against the roller 120 under the action of the elastic force, thereby polishing the roller 120. In addition, the present embodiment also provides the support seat 130 to drive the polisher 140 to move along the axial direction of the roller 120, so as to realize automatic polishing of the circumference of the roller 120, thereby improving the polishing efficiency and polishing effect. The present embodiment provides the first detector 170, the second detector 210, the telescopic rod 180 and the controller 190, so as to compensate for the pressure of the polisher 140 on the roller 120 when the elastic force is insufficient, thereby improving the polishing effect.

[0093] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
