Description

Technical Field

[0001] This utility model belongs to the field of cold rolling technology, and specifically relates to a brush roller replacement device for a cold-rolled strip steel brush washing machine. Background Technology

[0002] On the cold-rolled strip steel production line, the brushing roller is the core component of the brushing machine, used to remove iron oxide scale, oil stains and other impurities from the surface of the strip steel. The brushing roller will gradually wear out during use, so it needs to be replaced regularly.

[0003] A search revealed a method for precise and efficient replacement of brush rollers in the cleaning section, disclosed in patent CN115382922B. This method connects the brush roller replacement system to an HMI interface, allowing selection of the brush roller to be replaced and execution of the replacement operation. Simultaneously, the replacement trolley automatically moves to the position of the brush roller to be replaced, and the lifting device automatically rises to the brush roller loading / unloading position. Subsequently, the replacement trolley and the overhead crane work together to replace the brush roller. However, the above brush roller replacement method relies on the overhead crane and manual labor, which not only takes a long time to disassemble and assemble the equipment, seriously affecting production efficiency, but also makes it difficult to center and adjust the parallelism of the rollers, resulting in decreased installation accuracy and affecting the washing quality.

[0004] A search revealed a roller changing trolley for squeeze rollers and brush rollers, with prior art announcement number CN222697114U. This device controls the operation of the moving trolley via an electrical remote control. A counterweight is detachably mounted in the fixed frame of the moving trolley, and a clamp is mounted on the moving trolley via a clamp adjusting device. The clamp is moved up and down or swung left and right by the cooperation of the first and second moving components in the clamp adjusting device, thereby aligning and clamping the clamp with the roller to be replaced. After the roller is removed from the equipment, the old roller needs to be manually removed from the roller changing trolley, and then the new roller needs to be manually installed on the roller changing trolley, resulting in a decrease in roller replacement efficiency.

[0005] Therefore, a brush roller replacement device is needed for a cold-rolled strip steel brushing machine, which can quickly and automatically disassemble and install the brush roller. Summary of the Invention

[0034] A brush roller replacement device for a cold-rolled strip steel brushing machine, the working process of which is as follows:

[0035] The washing machine is stopped and the fixing bolts and coupling of the old washing roller 5 are loosened. Then, the transfer mechanism 3, controlled by an external power source, carries the clamping mechanism 1 and the auxiliary installation mechanism 2 along the track 4 to the side of the old washing roller 5. Then, the hydraulic motor IV 3032 in the displacement mechanism II 303 controls the sprocket in the gear box II 3034 to cooperate with the chain guide rail II 3031 through the reducer II 3033, and controls the clamping mechanism 1 to move forward along the support rod 301 and approach the washing roller 5.

[0036] Subsequently, the hydraulic motor I 1061 in the clamping mechanism 1 controls the screw jack 106 to drive the sliding box 104 to rise and fall along the connecting column 103, thereby aligning the slot on the fixed block 1052 with the central axis of the brush roller 5; then, the manual hydraulic pump 1071 is operated, and the jack II 1074 is controlled to run through the reversing valve 1072, so that the jack II 1074 and the connecting plate I 1051 cooperate to control the adjusting frame 105 to make a large-scale angle adjustment. Then, the handwheel 108 is turned, and the gear on the handwheel 108 meshes with the gear ring 1081 to drive the adjusting frame 105 to rotate within a small range, thereby making a fine angle adjustment of the fixed block 1052, so that the slot on the fixed block 1052 is more accurately aligned with the central axis of the brush roller 5;

[0037] The displacement mechanism II 303 controls the clamping mechanism 1 to continue moving forward until the central shaft of the brushing roller 5 is inserted into the slot on the fixing block 1052. Then, the reversing valve 1072 is controlled to reverse, so that the jack I 1073 pushes the clamping block 1053 to hold the brushing roller 5 tightly. Then, the displacement mechanism II 303 is activated to control the clamping mechanism 1 to retract, and the brushing roller 5 is pulled out of the brushing machine.

[0038] The displacement control mechanism II 303 drives the clamping mechanism 1 to continuously retract, leaving operating space for the auxiliary installation mechanism 2. Then, the hydraulic motor II 2022 controls the roller to move the connecting plate II 202 along the limit frame 201 to above the support rod 301. Then, the hydraulic motor III 2031 drives the sprocket in the gear box I 2034 to mesh with the chain guide rail I 2033 through the reducer I 2032, thereby driving the moving plate 2035 to move laterally along the connecting plate II 202 until the sliding frame 2041 moves below the brush roller 5. Then, a pair of jacks III 204 operate synchronously, controlling the sliding frame 2041 to rise until the support groove at the top of the sliding frame 2041 is in contact with the central axis of the brush roller 5. Then, the jack I 1073 is controlled to drive the clamping block 1053 to retract, while the displacement mechanism II 303 controls the clamping mechanism 1 to retract, so that the central axis of the brush roller 5 disengages from the slot on the fixed block 1052. In this way, the old brush roller 5 is removed from the clamping mechanism 1.

[0039] Then, a pair of jacks III 204 operate synchronously, controlling the sliding frame 2041 to rise again, lifting the new scrubbing roller 5 placed in the support groove at the bottom of the sliding frame 2041. Then, the displacement mechanism II 303 controls the clamping mechanism 1 to move forward, so that the central axis of the new scrubbing roller 5 is inserted into the slot on the fixing block 1052. Then, the jack I 1073 is controlled to drive the clamping block 1053 to hold the new scrubbing roller 5 tightly. The pair of jacks III 204 are controlled to operate synchronously, so that the sliding frame 2041 is lowered. After the central axis of the new scrubbing roller 5 is disengaged from the support groove on the sliding frame 2041, the hydraulic motor II 2022 controls the roller to drive the connecting plate II 202 to reset along the limit frame 201. Then, the displacement mechanism II 303 and the clamping mechanism 1 drive the new scrubbing roller 5 forward until the new scrubbing roller 5 is installed in the scrubbing machine.
