Description

Technical Field

[0001] This utility model relates to the field of tension control technology, specifically to a tension control device for preventing scratches on steel strip shearing machines. Background Technology

[0002] Currently, most steel strip processing equipment in the industry is equipped with basic tension control mechanisms (such as tension rollers and cylinder drive components) and surface scraping components, which can basically meet the needs of simple processing scenarios. However, with the continuous improvement of the requirements for steel strip processing precision and surface quality in high-end manufacturing, existing equipment has gradually exposed problems such as insufficient flexibility in tension control, unstable scraping effect, and easy accumulation of slag on scraping components. Especially in high-speed, continuous steel strip processing scenarios, traditional equipment is difficult to achieve dynamic coordination between scraping and conveying. The burrs left by scraping can easily scratch the surface of the steel strip again, which restricts the production efficiency of high-quality steel strips. It is urgent to achieve a synergistic improvement in tension control and surface scraping through structural optimization. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4 This utility model provides a technical solution: A second support 2 is fixedly installed on the outside of the first support 1 by welding. A first cylinder 3 is fixedly installed on the top of the second support 2 by bolts. A first roller seat is fixedly installed on the top of the first cylinder 3 by bolts. A first tension roller 4 is installed inside the first roller seat through a bearing. The first cylinder 3 can drive the first roller seat to drive the first tension roller 4 to move up and down, so as to achieve height adjustment.

[0016] A third support 5 is welded and fixed to the outside of the first support 1. A second cylinder 6 is fixedly installed at the bottom of the third support 5 by bolts. A second roller seat is fixedly installed at the bottom of the second cylinder 6 by bolts. A second tension roller 7 is installed inside the second roller seat through a bearing. The second cylinder 6 can drive the second roller seat to drive the second tension roller 7 to move up and down, which works with the first tension roller 4 to realize the adjustment of the steel belt tension.

[0017] Start cylinders 3 and 6. Based on the material, thickness and other parameters of the steel strip to be cut, precisely adjust the height of tension roller 4 and tension roller 7: cylinder 3 extends and retracts to drive tension roller 4 to move up and down, and cylinder 6 extends and retracts to drive tension roller 7 to move up and down. The initial tension of the steel strip is preset by the height difference between the two to ensure that the tension meets the requirements of the cutting process.

[0018] A motor 8 is bolted to the center of bracket 5. The output of motor 8 is fixedly connected to one end of drive roller 9 via a coupling. The other end of drive roller 9 is rotatably mounted on a pre-set mounting base of bracket 1 via a bearing. Motor 8 drives drive roller 9 to rotate stably around its own axis, providing power for the steel belt conveyor. Both ends of drive roller 9 are fixedly connected to cranks 11 via keys. Cranks 11 rotate synchronously with drive roller 9, forming an eccentric extrusion driving force. Meanwhile, an outer sleeve 10 is welded to the outside of cylinder 6, serving as the mounting carrier for subsequent linkage components.

[0019] The steel strip to be cut is sequentially passed around the drive roller 9, the second tension roller 7, and the first tension roller 4. The motor 8 is started, and the output end of the motor 8 drives the drive roller 9 to rotate through the coupling. The drive roller 9 drives the steel strip to be stably conveyed along the preset path by friction and feeds it to the cutting mechanism.

[0020] An elastic telescopic rod 12 is fixedly installed on the top of the outer sleeve 10 by bolts. A plate is fixedly connected to the top of the elastic telescopic rod 12 by bolts. A vertical plate 13 is fixedly connected to the end of the plate away from the elastic telescopic rod 12 by welding. The top of the vertical plate 13 is the force-bearing end face, which is squeezed and adapted to the outer edge of the crank 11. When the crank 11 rotates, it can periodically squeeze the vertical plate 13. The elastic telescopic rod 12 can achieve buffering and reset by extension and retraction.

[0021] The outer end face of the outer sleeve 10 is fixedly mounted with a support seat 14 by bolts. The shaft body is fixedly connected to the inside of the support seat 14 by interference fit. The cleaning strip 15 is rotatably mounted on the outside of the shaft body by bearing. The scraping edge of the cleaning strip 15 faces the steel strip conveying path and is used to clean the burrs on the surface of the steel strip. The top of the cleaning strip 15 is fixedly connected with an elastic strip 16 by adhesive. The end of the elastic strip 16 away from the cleaning strip 15 is fixedly connected to the outside of the second cylinder 6 by welding. In the initial state, the elastic strip 16 is in a pre-stretched state. The elastic tension makes the scraping edge of the cleaning strip 15 fit tightly against the surface of the steel strip.

[0022] During the steel belt conveying process, the scraper 15, under the pre-stretch elastic force of the elastic strip 16, continuously and closely adheres to the surface of the steel belt, and scrapes away burrs and impurities on the surface in real time as the steel belt moves, so as to avoid burrs scratching the steel belt or damaging the slitting tools during the slitting process, thus ensuring the surface quality of the steel belt.

[0023] Simultaneously, when the drive roller 9 rotates, it drives the cranks 11 at both ends to rotate synchronously. The outer edge of the crank 11 periodically presses the top end face of the vertical plate 13. When the eccentric end of the crank 11 rotates to contact the vertical plate 13, it generates a downward pressing force to push the vertical plate 13 down. The vertical plate 13 drives the elastic telescopic rod 12 to compress downward. The elastic telescopic rod 12 stores elastic potential energy to buffer the pressing force. When the eccentric end of the crank 11 rotates away from the vertical plate 13, the elastic telescopic rod 12 releases elastic potential energy and pushes the vertical plate 13 to reset upward, completing one pressing and resetting cycle.

[0024] During the process of the vertical plate 13 being pressed down by the crank 11 and compressing the elastic telescopic rod 12, the bottom of the vertical plate 13 exerts a downward squeezing force on the top of the cleaning strip 15. This squeezing force overcomes the elastic tension of the elastic strip 16, causing the cleaning strip 15 to deflect downward with the shaft inside the support seat 14 as the fulcrum. When the cleaning strip 15 deflects downward, the angle of its scraping edge changes slightly. The burrs and impurities remaining on the scraping edge slide down the surface of the cleaning strip 15 under the action of gravity, realizing the self-cleaning of the cleaning strip 15 and avoiding the accumulation of burrs that affect the cleaning effect. When the vertical plate 13 is reset, the cleaning strip 15 is reset under the action of the elastic tension of the elastic strip 16, and the scraping edge is tightly attached to the surface of the steel strip again to continue burr cleaning.

[0025] The working principle of this utility model is as follows: start cylinder 3 and cylinder 6, adjust the height of tension roller 4 and tension roller 7, and preset the initial tension; check the adhesion between the cleaning strip 15 and the steel strip surface to ensure that the elastic strip 16 is in a normal pre-stretched state; start motor 8 for trial operation to confirm that the drive roller 9 and crank 11 rotate smoothly.

[0026] The steel strip passes sequentially around the drive roller 9, the second tension roller 7, and the first tension roller 4, and enters the shearing mechanism; the motor 8 drives the drive roller 9 to rotate and transport the steel strip, and the scraper 15 immediately scrapes off the burrs on the surface of the steel strip; the crank 11 rotates with the drive roller 9 and periodically squeezes the vertical plate 13, and the scraper 15 is dynamically fine-tuned by the extension and retraction of the elastic telescopic rod 12, which also serves to reset the vertical plate 13.

[0027] When the vertical plate 13 is pressed down by the crank 11 and compresses the elastic telescopic rod 12, the vertical plate 13 exerts a downward squeezing force on the cleaning strip 15, causing the cleaning strip 15 to deflect downward with the shaft inside the support seat 14 as the fulcrum, thereby causing the burrs remaining on the cleaning strip 15 to slide down its surface due to gravity.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
