Description

Technical Field

[0001] This invention relates to the field of submerged roller processing technology, and more specifically to a submerged roller surface treatment device. Background Technology

[0002] Submerged rolls are one of the core pieces of equipment in continuous hot-dip galvanizing production lines. They are completely immersed in molten zinc in a high-temperature zinc pot and are used to change the running direction of the strip steel and provide stable support. The main structure of the submerged roll consists of a shaft head and a shaft body. After the submerged roll has been used for a long time, zinc dross will adhere to the surface, the coating will wear or the substrate will crack. In order to enable the submerged roll to be used normally, the surface of the submerged roll needs to be treated.

[0003] Application number CN202510971147.3 relates to the field of grinding equipment technology. This invention discloses a grinding device for processing the surface of submerged rollers, comprising: a base, with three rotating cylinders equidistantly mounted circumferentially inside the base, and both ends of the rotating cylinders extending to the outside of the base. A connecting ring is fixedly mounted on the top surface of each rotating cylinder. This application includes a clamping assembly, a rotating assembly, and an adjusting assembly. After three submerged rollers are clamped and fixed at one end by the three clamping assemblies, a servo motor drives the threaded sleeve on the surface of a reciprocating screw to move up and down reciprocally. During grinding of one side of the submerged rollers by an arc-shaped grinding plate, the rotating assembly enables the three clamped submerged rollers to rotate. Then, the three arc-shaped grinding plates simultaneously perform comprehensive grinding on the surface of the rotating submerged rollers, facilitating the processing of multiple workpieces at once and improving the production efficiency of submerged roller processing.

[0004] However, this patent does not allow for the processing of the shaft head of the submerged roller, which affects the processing effect of the submerged roller.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a surface treatment device for submerged rollers that can effectively solve the above-mentioned technical problems.

[0012] Furthermore, the roller surface treatment assembly includes: a limiting rod; a linear motion module mounted on the limiting rod; and a treatment head for treating the submerged roller. The processing head includes: a fixed frame; a second electric telescopic rod fixedly mounted on the fixed frame; a fixed block fixedly mounted on the output shaft of the second electric telescopic rod; a connecting block fixedly mounted on the fixed frame; a rotating shaft rotatably mounted on the connecting block; a spring fixedly mounted on the rotating shaft; a connector fixedly mounted on the rotating shaft; a cleaning part fixedly mounted on the connector; and a wiping part fixedly mounted on the cleaning part.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a surface treatment device for submerged rollers. When grinding the head of a submerged roller, an electric telescopic rod is used to control the chuck to apply appropriate pressure to the head of the submerged roller. Then, a second motor is started to drive the screw to rotate, controlling the support frame to move the chuck on the head of the submerged roller. By controlling the forward and reverse rotation of the second motor, the chuck is driven to reciprocate on the head of the submerged roller, thereby grinding the head of the submerged roller. When the chuck moves, it drives the fixed sleeve to move synchronously, causing the rotating block to slide on the surface of the guide rod through the slide groove, and the guide block to slide in the guide groove. Under the limitation of the guide groove and the guide block, the rotating block is driven to rotate, thereby causing the chuck to rotate, and the head of the submerged roller is thoroughly ground, resulting in a good grinding effect.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 11As shown, the present invention provides a surface treatment device for a submerged roller, comprising: a frame 1; a slide 3 slidably mounted on the frame 1; a linear drive assembly 2 for moving the slide 3; an end treatment assembly 4 for fixing the end of the submerged roller; and a roller surface treatment assembly for treating the roller surface. The submerged roller is placed on the slide 3, then fixed by the end treatment assembly 4, and then the roller surface treatment assembly 5, in conjunction with the linear drive assembly 2, treats the zinc slag and coating on the roller surface.

[0022] The linear drive assembly 2 includes: a motor 21 fixedly mounted on the frame 1; a gear 22 fixedly mounted on the motor 21; a rack 23 meshing with the gear 22; a connecting rod 24 fixedly mounted on the rack 23; and a slide 3 fixedly mounted on the connecting rod 24. After the submerged roller is fixed by the end processing assembly 4, when the roller surface of the submerged roller needs to be processed, the motor 21 is started to drive the gear 22 to rotate. The gear 22 and the rack 23 drive the connecting rod 24 to slide on the frame 1, thereby driving the slide 3 and the submerged roller to slide on the frame 1. At this time, the submerged roller cooperates with the roller surface processing assembly 5 to realize the processing work on the roller surface.

[0023] Specifically, the end processing assembly 4 includes: a connecting frame 41, which is fixedly mounted on the slide 3; a second motor 42 fixedly mounted on the connecting frame 41; a screw 43 fixedly mounted on the second motor 42; a support frame 44 threaded onto the screw 43; a fixing sleeve 47 rotatably mounted on the support frame 44; an electric telescopic rod 48 fixedly mounted on the fixing sleeve 47; a fixing rod 49 fixedly mounted on the electric telescopic rod 48; a hinge rod 410 rotatably mounted on the fixing rod 49; and a rotating rod 411 rotatably mounted on the hinge rod 410; and a fixed... The chuck 412 is installed on the rotating rod 411. The rotating rod 411 is slidably connected to the fixed sleeve 47. The support frame 44 is slidably connected to the connecting frame 41. After the submerged roller is placed in the slide 3, the motor 42 is started to drive the screw 43 to rotate. Under the limit of the connecting frame 41, the support frame 44 moves along the axial direction of the connecting frame 41, so that the support frame 44 drives the chuck 412 to move towards the submerged roller. Then, the electric telescopic rod 48 is started to pull the fixed rod 49 to move. The fixed rod 49 pulls the hinge rod 410 to drive the rotating rod 411 to move. The rotating rod 411 drives the chuck 412 to clamp and fix the shaft end of the submerged roller.

[0024] After the end processing component 4 is fixed, it is processed by the roller surface processing component 5. The roller surface processing component 5 includes: a limiting rod 51, which is fixedly installed on the frame 1; a linear movement module 52 installed on the limiting rod 51, one set of linear modules drives the processing head 53 to adjust laterally, thereby adjusting the grinding position; and a processing head 53 for processing the submerged roller. Another set of linear movement modules is installed on the limiting rod 51 to drive the processing head 53 to move down toward the submerged roller. When the surface of the submerged roller needs to be processed, the processing head 53 can effectively contact the submerged roller through the cooperation of the two sets of linear modules, thereby achieving the surface processing of the submerged roller.

[0025] The linear motion module 52 is preferably a ball screw module.

[0026] The processing head 53 includes: a fixed frame 531; an electric telescopic rod 532 fixedly mounted on the fixed frame 531; a fixed block 533 fixedly mounted on the output shaft of the electric telescopic rod 532; a connecting block 534 fixedly mounted on the fixed frame 531; a rotating shaft 535 rotatably mounted on the connecting block 534; a spring 536 fixedly mounted on the rotating shaft 535; a connector 537 fixedly mounted on the rotating shaft 535; a cleaning part 538 fixedly mounted on the connector 537; and a wiping part 539 fixedly mounted on the cleaning part 538.

[0027] When the processing head 53 moves down and contacts the submerged roller, the cleaning part 538 contacts the surface of the submerged roller. The cleaning part 538 is a grinding plate, which grinds the submerged roller and removes the zinc slag and coating on the submerged roller, thus achieving surface treatment of the submerged roller, which is convenient for repair and reuse.

[0028] Specifically, the fixed frame 531 moves down, causing the cleaning section 538 to move down. When the surface of the submerged roller has an annular groove, the electric telescopic rod 532 is activated to move the fixed block 533 down, thereby causing the brush head 5311 to contact the submerged roller. Thus, while the cleaning section 538 cleans the submerged roller, the brush head 5311 simultaneously cleans the inside of the annular groove, improving the cleaning effect on the submerged roller.

[0029] It should be noted that a telescopic rod 5331 is rotatably mounted on the fixed block 533; the telescopic rod 5331 is rotatably mounted on the cleaning part 538; a brush head 5311 is fixedly mounted on the fixed block 533; and the spring 536 is fixedly mounted on the connecting block 534. After the submerged roller is cleaned, it needs to be rinsed with water to wash off the zinc slag and coating on the submerged roller, thereby improving the overall cleaning effect of the submerged roller. After the submerged roller is rinsed, the electric telescopic rod 532 is activated to move the fixed block 533 upward. At this time, the telescopic rod 5331 deforms synchronously. When the telescopic rod moves to its maximum stroke, the electric telescopic rod 532 continues to move the fixed block 533. At this time, the fixed block 533 pulls the cleaning part 538 through the telescopic rod 5331 to rotate through the connector 537 and the rotating shaft 535, causing the wiping part 539 to rotate and become parallel to the submerged roller. At this time, the fixed frame 531 moves downward to wipe the surface of the submerged roller, thereby improving the cleaning effect of the submerged roller.

[0030] When the connector 537 rotates, the spring 536 deforms synchronously. When the cleaning part 538 needs to be reset, the electric telescopic rod 532 drives the fixing block 533 to reset. At this time, the spring 536 resets and drives the cleaning part 538 to reset, which is convenient for subsequent use. It should be noted that the cleaning part 538 is provided with a groove for the fixing block 533 to slide. The size of the groove is larger than that of the fixing block 533 to avoid interference.

[0031] It should be noted that the side of the chuck 412 that contacts the submerged roller is a polished surface, resulting in a relatively weak clamping force. This may lead to unstable fixation during actual use. Therefore, an airbag 511 is fixedly installed on the limiting rod 51, and the chuck 412 is hollow. A telescopic sleeve rod 4121 is installed on the chuck 412. The airbag 511 is connected to the telescopic sleeve rod 4121 via an air pipe. A telescopic plate 4122 is fixedly installed on the telescopic sleeve rod 4121. A fixing head 4123 is fixedly installed on the telescopic plate 4122. A limiting hole is provided on the chuck 412 to cooperate with the fixing head 4123. When the airbag 511 is compressed, the gas inside the airbag 511 is transported to the telescopic sleeve rod 4121 through the air pipe. Inside the rod 4121, the telescopic sleeve 4121 extends, which in turn causes the telescopic plate 4122 to slide inside the clamp 412, allowing the fixing head 4123 to extend from the limiting hole and contact the submerged roller shaft head, thereby fixing the submerged roller. It should be noted that multiple sets of fixing heads 4123 are provided, and multiple sets of fixing heads 4123 form a fixing surface to ensure the stability of fixing the submerged roller shaft head. When the processing head 53 moves down to process the submerged roller surface, the linear movement module 52 will squeeze the air bag 511, which will cause the gas in the air bag 511 to enter the telescopic sleeve 4121, causing the fixing head 4123 to move out, and then fix the submerged roller shaft head through the fixing head 4123, ensuring the fixing effect of the submerged roller.

[0032] Finally, it should be noted that after the surface treatment of the submerged roller is completed, the shaft end of the submerged roller needs to be treated. A guide rod 45 is fixedly installed on the connecting frame 41; a rotating block 46 is fixedly installed on the fixing sleeve 47; a sliding groove 461 is provided on the rotating block 46; a guide block 462 is fixedly installed on the sliding groove 461; a guide groove 451 is provided on the guide rod 45; the guide groove 451 cooperates with the guide block 462. When grinding the shaft end of the submerged roller is required, the electric telescopic rod 48 controls the chuck 412 to apply appropriate pressure to the shaft end of the submerged roller, and then the motor 42 is started. Rotating the screw 43 controls the support frame 44 to move the chuck 412 on the submerged roller head. By controlling the forward and reverse rotation of the motor 42, the chuck 412 is driven to reciprocate on the submerged roller head, thereby polishing the submerged roller head. When the chuck 412 moves, it drives the fixed sleeve 47 to move synchronously, causing the rotating block 46 to slide on the surface of the guide rod 45 through the slide groove 461, and causing the guide block 462 to slide in the guide groove 451. Under the limitation of the guide groove 451 and the guide block 462, the rotating block 46 is driven to rotate, thereby causing the chuck 412 to rotate, so as to fully polish the submerged roller head, resulting in a good polishing effect.

[0033] In addition, when processing the head of the submerged roller, a set of linear movement modules on the limit rod 51 will not be activated. At this time, the processing head 53 will not be in contact with the submerged roller, the airbag 511 will not be compressed, and the airbag 511 will not supply air to the chuck 412 through the air pipe. Therefore, the fixed head 4123 will not extend, and then contact the head of the submerged roller through the grinding surface on the chuck 412 to achieve the processing of the head of the submerged roller.
