Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, in particular to a surface cleaning device for an unwinding steel strip. Background Art

[0002] Stainless steel pipes are produced from steel strips. As raw materials, steel strips are very large in size and weight. During transportation and storage, it is impossible to protect each roll of steel strip from dust separately. At most, a layer of dustproof cloth can be covered during storage in the warehouse. This dustproof method has little effect on the entire production, processing, transportation and storage process of the steel strip, resulting in each roll of steel strip being contaminated with dust to varying degrees. Therefore, cleaning and dust removal steps are required during the unwinding of the steel strip before the production of stainless steel pipes.

[0003] Currently, there is no cleaning device for steel strip unwinding. Many workshops use a simple rack to press a rag to wipe the dust on the upper surface. There are two main shortcomings: 1. After wiping for a period of time, dust accumulates on the rag, and the cleaning effect decreases; 2. The lower surface of the steel strip is not cleaned and dusted, which is easy to cause scratches when the steel strip is extruded and formed later. Therefore, there are defects, and a cleaning device that can comprehensively, continuously and efficiently clean the steel strip is urgently needed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a device for cleaning the surface of an unwinding steel strip, which is used to solve the problem of poor cleaning effect of cleaning the steel strip by a fixed rag during the production of the existing stainless steel pipes.

[0025] The corresponding shaft seat 1 of the driving roller 5 is fixed on the fixed box 1, and the driving roller 5 is in transmission connection with the driving motor 8 installed on the fixed box 1. A horizontal relief through groove is provided at the position of the fixed box 1 corresponding to the support roller 4. A shaft seat guide rail 9 perpendicular to the conveying direction of the steel strip 3 is horizontally provided at the position of the fixed box 1 corresponding to the support roller 4. The corresponding shaft seat 1 of the support roller 4 is slidably connected with the shaft seat guide rail 9, and a tension spring 10 is horizontally arranged between the side of the fixed box 1 corresponding to the shaft seat 1 of the support roller 4 away from the driving roller 5.

[0026] On both sides of the steel strip 3 between the support roller 4 and the driving roller 5 in the fixed box 1, and above and below the belt 7, a pressure roller 11 and a supporting roller 12 parallel to the conveying direction of the steel strip 3 are respectively arranged. The pressure roller 11 and the supporting roller 12 are symmetrically arranged up and down, and two pressure rollers 11 and two supporting rollers 12 are respectively symmetrically arranged horizontally on both sides of the steel strip 3. Vertical relief through grooves are provided at the positions of the fixed box 1 corresponding to the pressure roller 11 and the supporting roller 12. Both ends of the pressure roller 11 and the supporting roller 12 respectively penetrate through the fixed box 1 and are connected with the second shaft seat 13. Above and below the second shaft seat 13 on the fixed box 1, a third shaft seat 14 is fixedly connected, and a positive and negative thread screw rod 15 in transmission connection with the second shaft seat 13 is vertically installed between the third shaft seats 14.

[0027] Sprockets 16 are installed at the lower ends of the positive and negative thread screw rods 15, and the sprockets 16 are in transmission connection through a chain 17. A chain guide rail 21 movably sleeved on the surface of the chain 17 is fixedly connected to the fixed box 1. One of the positive and negative thread screw rods 15 is in transmission connection with the tensioning motor 18 installed on the fixed box 1. The driving motor 8 and the tensioning motor 18 are both fixedly connected to the fixed box 1 through a connecting frame 20. The chain 17, the chain guide rail 21 and the tensioning motor 18 are all arranged below the fixed box 1.

[0028] Two dust removal brushes 19 parallel to the conveying direction of the steel strip 3 and located on both sides of the steel strip 3 are movably inserted into the fixed box 1. Dust removal bristles are arranged at the top and bottom of the dust removal brushes 19. Installation slots are provided at the positions of the fixed box 1 corresponding to the dust removal brushes 19. The two dust removal brushes 19 are respectively located inside the belt 7 between the pressure roller 11, the supporting roller 12 and the support roller 4 and between the pressure roller 11, the supporting roller 12 and the driving roller 5.

[0029] Working principle: When the steel strip 3 is unrolled, it passes through the fixed box 1 and the belt 7 and is conveyed from front to back. The tensioning motor 18 drives the second shaft seat 13 to move vertically and approach each other through the positive and negative thread screw rod 15, the sprocket 16 and the chain 17. The pressure roller 11 and the supporting roller 12 squeeze the belt 7 against each other, so that the upper and lower belt surfaces of the belt 7 are close to and attached to the upper and lower surfaces of the steel strip 3. At this time, the tension spring 10 is stretched, the two shaft seats 1 approach each other, and the support roller 4 approaches the driving roller 5 under the guidance of the shaft seat guide rail 9 to adapt to the change in the shape of the belt 7. When the dust removal fluff 6 contacts the steel strip 3, the steel strip 3 is normally unrolled and conveyed, and the upper and lower surfaces of the steel strip 3 can be comprehensively and passively dusted.

[0030] The driving motor 8 drives the belt 7 to run through the driving roller 5 and the supporting roller 4. The belt 7 can drive the dust-removing fluff 6 to actively wipe the dust on the upper and lower surfaces of the steel strip 3. When the upper and lower belt surfaces of the belt 7 approach each other, they will also contact the dust-removing brush 19, and the dust on the dust-removing fluff 6 is brushed off by the dust-removing brush 19. The dust-removing brush 19 is inserted and installed, which is convenient for separate cleaning and replacement, so as to achieve the purpose of continuously and efficiently cleaning the surface of the unwound steel strip 3 in all directions.

[0031] The tensioning motor 18 drives the second shaft seat 13 to move vertically away from each other through the right and left hand screw 15, the sprocket 16 and the chain 17. The pressing force of the pressing roller 11 and the supporting roller 12 on the belt 7 gradually decreases, so that the upper and lower belt surfaces of the belt 7 are separated from the upper and lower surfaces of the steel strip 3. At this time, the tension spring 10 drives the two first shaft seats 2 to move away from each other, and the supporting roller 4 moves away from the driving roller 5 under the guidance of the shaft seat guide rail 9 to tension the belt 7 to adapt to the change of shape, and then stops the dust removal work on the steel strip 3.
