Description

Technical Field

[0001] This invention relates to the field of tension measuring roller technology, and in particular to a tension measuring roller. Background Technology

[0002] Tension measuring rolls are frequently used in steel rolling production and processing lines to measure tension, serving as feedback values ​​for tilt adjustment and tension closed-loop control. Since tension measuring rolls are usually installed at the equipment inlet, their surfaces are very prone to accumulating dust and foreign matter. If this dust and foreign matter are not cleaned in time, it will affect the quality of the product. Therefore, it is essential to clean the dust and foreign matter adhering to the surface of the tension measuring roll.

[0003] A search revealed a Chinese patent with publication number CN116603790A, which discloses a tension measuring roller surface cleaning device, including a worktable; a tension measuring roller rotatably connected to the worktable; a mounting plate fixedly connected to the worktable; the mounting plate being perpendicular to the tension measuring roller; a support frame slidably connected to the worktable; a cylinder fixedly connected to the mounting plate; the output end of the cylinder passing through the mounting plate and fixedly connected to one end of the support frame; a moving component connected to the support frame; a cleaning mechanism connected to the support frame; the moving component for moving the cleaning mechanism on the support frame; the cleaning mechanism for cleaning the tension measuring roller; and a steel lifting component connected to the worktable for lifting the steel strip on the tension measuring roller.

[0004] In the aforementioned technology, although the design of the cleaning mechanism makes cleaning the surface of the tension roll more convenient, the device requires the steel strip on the surface of the tension roll to be lifted by the steel lifting assembly before cleaning. This means the steel strip is removed from the surface of the tension roll before subsequent cleaning can be carried out. However, cleaning the tension roll in this way makes it impossible to detect the tension of the steel strip simultaneously during the cleaning process, causing the steel strip to stop conveying and requiring waiting for the tension roll to be cleaned. This prolongs the production and processing time of the steel strip and reduces work efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that tension detection cannot be performed simultaneously when cleaning the surface of the tension measuring roller in the prior art.

[0011] In one embodiment of the present invention, two connecting blocks are fixedly connected to both ends of the movable plate, and an electric telescopic rod is fixedly connected to one end of each connecting block. The output ends of the two electric telescopic rods are jointly fixedly connected to a brush plate.

[0012] In one embodiment of the present invention, a ring-shaped water pipe is fixedly connected to the side wall of the vacuum cleaner, a plurality of nozzles are provided at the bottom of the ring-shaped water pipe, a water pump is installed at one end of the top of the support frame, and the output end of the water pump is connected to the ring-shaped water pipe.

[0013] In one embodiment of the present invention, one end of the annular water pipe is connected to a first connecting pipe, one end of the first connecting pipe extends to the outside of the support frame and is slidably connected to the support frame, the output end of the water pump is connected to a second connecting pipe, and the first connecting pipe and the second connecting pipe are connected by a spring water pipe.

[0014] In one embodiment of the present invention, the support frame is provided with a through groove on one end side wall of the first connecting pipe, and a movable block is slidably connected in the through groove. The first connecting pipe passes through the movable block and is slidably connected to the movable block.

[0015] In one embodiment of the present invention, the movable block is provided with flanges at both ends of the through groove, and the flanges are slidably connected to the support frame.

[0016] In one embodiment of the present invention, a telescopic rod is rotatably connected to one end of the outer wall of the first connecting pipe, the top of the telescopic rod is rotatably connected to the second connecting pipe, and the telescopic rod is located inside the spring water pipe.

[0017] In one embodiment of the present invention, a first rotating shaft is fixedly connected to one end of the outer wall of the first connecting pipe, a first connecting lug is fixedly connected to the bottom of the telescopic rod, the first rotating shaft is rotatably connected to the first connecting lug, a second rotating shaft is fixedly connected to one end of the outer wall of the second connecting pipe, a second connecting lug is fixedly connected to the top of the telescopic rod, and the second rotating shaft is rotatably connected to the second connecting lug.

[0020] The technical solution of the present invention has the following advantages compared with the prior art:

[0021] The tension measuring roller of this invention features a dust collection mechanism positioned above the roller body. This allows the steel strip to pass over the bottom of the roller body, enabling the tension measuring roller to be cleaned while simultaneously detecting the tension of the steel strip, thus not affecting the production and processing of the steel strip. The dust collection mechanism includes a vacuum cleaner that absorbs dust adhering to the surface of the roller body. A cylinder design drives the vacuum cleaner to move up and down, adjusting the distance between the vacuum cleaner's input hood and the roller body. A motor drives a gear to rotate, which in turn drives a chain to rotate, causing a moving plate to reciprocate. During the movement of the moving plate, the vacuum cleaner moves along with the roller body, moving back and forth between the two ends above the roller body. Combined with the rotation of the roller body itself, this allows the vacuum cleaner to thoroughly clean the surface of the tension measuring roller.

[0022] The tension measuring roller described in this invention uses an electric telescopic rod to drive the brush plate to move up and down, thereby adjusting the distance between the brush plate and the tension measuring roller body, as well as the vertical distance between the brush plate and the dust collection hood. When there are firmly attached foreign objects on the cleaning roller that cannot be absorbed by the vacuum cleaner, the electric telescopic rod is used to drive the brush plate to move to the upper surface of the tension measuring roller body. In addition, when the moving plate moves, it will drive the brush plate to move together, so that the brush plate can brush the tension measuring roller body, thereby improving the cleaning effect of the roller surface of the tension measuring roller body. The brush plate is used when the tension measuring roller body is not inspecting the steel strip, thereby preventing the brush plate from brushing dust and foreign objects onto the steel strip, or the brush bristles on the brush plate from adhering to the steel strip, thus affecting the quality of the steel strip.

[0023] The tension measuring roller of this invention uses a water pump to deliver cleaning fluid into an annular water pipe, which is then sprayed out from a nozzle at the bottom of the annular water pipe to rinse the surface of the tension measuring roller body, thereby ensuring a more thorough cleaning. By placing the annular water pipe on the side wall of a vacuum cleaner, the vacuum cleaner can move the annular water pipe together, allowing the tension measuring roller body to be thoroughly rinsed. The design of the first connecting pipe, the second connecting pipe, and the spring water pipe allows the water pump to smoothly deliver the cleaning fluid into the annular water pipe without affecting the movement of the annular water pipe by the vacuum cleaner. The rinsing operation is performed when the tension measuring roller body is not used for tension testing of the steel strip, thereby avoiding any adverse effects of the rinsing fluid on the production and processing of the steel strip.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] Reference Figures 1-10 As shown, the present invention provides a tension measuring roller, comprising:

[0038] Tension roller body 1;

[0039] The dust collection mechanism is located above the tension measuring roller body 1;

[0040] Support seats 2 are provided at both ends of the tension roller body 1;

[0041] The vacuuming mechanism includes a support frame 3 and a vacuum cleaner 4. The bottom ends of the support plate 6 are fixedly connected to the tops of two support bases 2. Two cylinders 5 are fixedly connected to the top ends of the inner side of the support frame 3. The output ends of the two cylinders 5 are fixedly connected to the support plate 6. A gear 7 is rotatably connected to the bottom center of the support plate 6. The two gears 7 mesh with a chain 8. Support arms 9 are fixedly connected to the two ends of the sidewalls of the support plate 6. A slide rod 10 is fixedly connected to the bottom of the two support arms 9. The two ends of the slide rod 10 are fixed to the support arms 9 on the same side of the two support plates 6, and the slide rod 10 is located below the chain 8. A sliding plate 11 is slidably connected to one end of each sliding rod 10. A first sliding groove 12 is provided on the top of the sliding plate 11. A first slider 13 is slidably connected in the first sliding groove 12. A connecting column 14 is rotatably connected to the top of the first slider 13. The connecting column 14 is fixedly connected to the bottom of the chain 8. A vacuum cleaner 4 is installed at the bottom of the sliding plate 11. A vacuum cleaner hood 15 is provided at the input end of the vacuum cleaner 4 and is located directly above the tension roller body 1. A motor 16 is slidably connected to one end of the side wall of the support frame 3. The motor 16 is located above the support plate 6 and the output shaft of the motor 16 is downward. The output shaft of the motor 16 passes through the support plate 6 and is fixedly connected to the gear 7.

[0042] In this embodiment, when a large amount of dust adheres to the surface of the tension roller body 1, it is necessary to clean the dust to prevent it from affecting the quality of the steel strip. First, the vacuum cleaner 4 is turned on, and then the cylinder 5 is turned on, allowing the cylinder 5 to drive the vacuum cleaner 4 to move downwards. When the dust suction hood 15 at the input end of the vacuum cleaner 4 approaches the tension roller body 1, it can absorb the dust adhering to its surface. Next, the motor 16 is turned on, and the gear 7 rotates under the drive of the motor 16, thereby driving the chain 8 to rotate. When the chain 8 rotates, it will drive the connecting post 14 at its bottom to move together, thereby driving the first slider 1. 3. The movement of the moving plate 11 causes it to move back and forth on the slide bar 10. When the chain 8 rotates, the first slider 13 slides back and forth in the first slide groove 12 at the top of the moving plate 11. During the movement of the moving plate 11, the vacuum cleaner 4 can be moved together, allowing the vacuum cleaner 4 to move back and forth above the tension measuring roller body 1. At the same time, the tension measuring roller body 1 rotates during operation, allowing the vacuum cleaner 4 to thoroughly clean the roller surface of the tension measuring roller body 1. This allows the tension measuring roller body 1 to clean dust while detecting the tension of the steel strip, without stopping the machine and thus not affecting production efficiency.

[0043] Furthermore, such as Figure 2 As shown, two connecting blocks 17 are fixedly connected to both ends of the movable plate 11. An electric telescopic rod 18 is fixedly connected to one end of the connecting block 17. The output ends of the two electric telescopic rods 18 are fixedly connected to a brush plate 19.

[0044] In this embodiment, when the tension measuring roller body 1 is not performing tension detection on the steel strip, a more thorough cleaning can be performed on the tension measuring roller body 1. First, the electric telescopic rod 18 is opened. Driven by the electric telescopic rod 18, the brush plate 19 moves downwards. When the brush plate 19 contacts the tension measuring roller body 1, the motor 16 is turned on, driving the chain 8 to rotate. This causes the moving plate 11 to move back and forth on the slide rod 10, thereby driving the brush plate 19 to move back and forth on the tension measuring roller body 1. Simultaneously, in conjunction with the rotation of the tension measuring roller body 1, the brush plate 19... The brush 19 can remove dust and foreign objects that are difficult for the vacuum cleaner 4 to absorb from the surface of the tension roll body 1, thereby improving the cleaning effect. The vacuum cleaner 4 can be turned on during the brushing process. The dust suction hood 15 at the input end of the vacuum cleaner 4 is located above the brush 19. After the vacuum cleaner 4 is turned on, it can absorb the dust generated when the brush 19 is brushing. The brush 19 is used when the tension roll body 1 is not inspecting the steel strip, thereby preventing the brush 19 from brushing dust and foreign objects onto the steel strip, or the brush bristles on the brush 19 from adhering to the steel strip, which would affect the quality of the steel strip.

[0045] Furthermore, such as Figure 2 and Figure 9 As shown, a ring-shaped water pipe 20 is fixedly connected to the side wall of the vacuum cleaner 4. The ring-shaped water pipe 20 is located above the brush plate 19, so as not to block the brush plate 19 from moving downward. When the top of the brush plate 19 is flush with the ring-shaped water pipe 20, the dust cover 15 is located below the brush plate 19. Multiple nozzles 21 are provided at the bottom of the ring-shaped water pipe 20. A water pump 22 is installed at one end of the top of the support frame 3. The output end of the water pump 22 is connected to the ring-shaped water pipe 20.

[0046] In this embodiment, when the brush plate 19 removes the firmly attached dust and foreign matter from the tension roller body 1, some dust will still remain on the surface of the tension roller body 1 and will be difficult to remove by the brush plate 19. Therefore, the tension roller body 1 needs to be rinsed. Before rinsing, the vacuum cleaner 4 needs to be turned off to prevent it from absorbing the cleaning fluid, thus avoiding the situation where the dust inside the vacuum cleaner 4 becomes wetted by the cleaning fluid and becomes difficult to clean. Then, the input end of the water pump 22 is connected to a container containing the cleaning fluid via a water pipe. When the water pump 22 is turned on, the cleaning fluid flows into the annular water pipe 20 and is sprayed out from the nozzle 21 at the bottom of the annular water pipe 20 to rinse the tension roller body 1. During the rinsing process, the motor 16 is always on, that is, the connecting rod is rotating, so that the moving plate 11 moves back and forth on the slide bar 10, thereby driving the annular water pipe 20 to move back and forth above the tension roller body 1, so as to thoroughly rinse the tension roller body 1 and make the tension roller body 1 cleaner.

[0047] Furthermore, such as Figure 1 and Figure 5 As shown, one end of the annular water pipe 20 is connected to a first connecting pipe 23, one end of the first connecting pipe 23 extends to the outside of the support frame 3 and is slidably connected to the support frame 3, and the output end of the water pump 22 is connected to a second connecting pipe 24. The first connecting pipe 23 and the second connecting pipe 24 are connected by a spring water pipe 25.

[0048] In this embodiment, the first connecting pipe 23 and the second connecting pipe 24 are relatively rigid plastic pipes, thereby reducing the risk of the first connecting pipe 23 and the second connecting pipe 24 bending and dragging downwards like a flexible hose, which would affect the normal operation of the tension roller body 1. The design of the spring water pipe 25 allows the annular water pipe 20 to be pumped with cleaning fluid by the water pump 22 without affecting the movement of the annular water pipe 20.

[0049] Furthermore, such as Figure 1 and Figure 5 As shown, the support frame 3 has a through groove 26 on one side wall of the first connecting pipe 23. A movable block 27 is slidably connected in the through groove 26. The first connecting pipe 23 passes through the movable block 27 and is slidably connected to the movable block 27.

[0050] In this embodiment, the design of the through groove 26 and the movable block 27 allows the first connecting pipe 23 to be smoothly slidably connected to the support frame 3, while allowing one end of the first connecting pipe 23 to extend smoothly to the outside of the support frame 3. The movable block 27 is slidably connected to the first connecting pipe 23, allowing the annular water pipe 20 to move smoothly.

[0051] Furthermore, such as Figure 4 As shown, the movable block 27 is provided with flanges 28 at both ends of the through groove 26, and the flanges 28 are slidably connected to the support frame 3;

[0052] In this embodiment, the flange 28 is designed to limit the movement of the moving block 27, allowing the moving block 27 to slide up and down only within the through groove 26, thereby ensuring that the first connecting pipe 23 can always be slidably connected to the support frame 3.

[0053] Furthermore, such as Figure 1 and Figure 5 As shown, a telescopic rod 29 is rotatably connected to one end of the outer wall of the first connecting pipe 23. The top of the telescopic rod 29 is rotatably connected to the second connecting pipe 24, and the telescopic rod 29 is located inside the spring water pipe 25.

[0054] In this embodiment, the design of the telescopic rod 29 can limit the movement of the spring water pipe 25, preventing it from swinging too much during movement and coming into contact with a part of the steel strip or the tension roller body 1, thus affecting the production process.

[0055] Furthermore, such as Figure 7 and Figure 8 As shown, a first rotating shaft 30 is fixedly connected to one end of the outer wall of the first connecting pipe 23, a first connecting ear 31 is fixedly connected to the bottom of the telescopic rod 29, and the first rotating shaft 30 is rotatably connected to the first connecting ear 31. A second rotating shaft 32 is fixedly connected to one end of the outer wall of the second connecting pipe 24, a second connecting ear 33 is fixedly connected to the top of the telescopic rod 29, and the second rotating shaft 32 is rotatably connected to the second connecting ear 33.

[0056] In this embodiment, the design of the first rotating shaft 30 and the first connecting ear 31 allows the telescopic rod 29 to be smoothly rotatably connected to the first connecting tube 23, and the design of the second rotating shaft 32 and the second connecting ear 33 allows the telescopic rod 29 to be smoothly rotatably connected to the second connecting tube 24.

[0057] Furthermore, such as Figure 6 As shown, a connecting rod 34 is fixedly connected to one end of the side wall of the motor 16, and a second slider 35 is fixedly connected to one end of the connecting rod 34. The support frame 3 is provided with a second sliding groove 36 on one end of the side wall of the motor 16, and the second slider 35 is slidably connected to the second sliding groove 36.

[0058] In this embodiment, the design of the connecting rod 34, the second slider 35, and the second slide groove 36 allows the motor 16 to be smoothly slidably connected to the support frame 3, so that the motor 16 can move up and down together with the support plate 6, thereby not affecting the up and down movement of the vacuum cleaner 4.

[0059] Furthermore, such as Figure 3 and Figure 6 As shown, a third slider 37 is fixedly connected to one end of the support arm 9, and a third slide groove 38 is provided at both ends of the inner side wall of the support frame 3. The third slider 37 is slidably connected to the third slide groove 38.

[0060] In this embodiment, the design of the third slider 37 and the third slide groove 38 allows the support arm 9 to be slidably connected to the support frame 3, thereby making the support arm 9 more stable when moving up and down, and thus ensuring the stability of the vacuum cleaner 4 when moving up and down.

[0061] Working principle: When the tension measuring roller body 1 is performing tension testing on the steel strip, in order to prevent the production and processing of the steel strip from being affected by dust on the tension measuring roller body 1 and thus reducing quality, it is necessary to clean the dust on the tension measuring roller body 1. During operation, first turn on the vacuum cleaner 4, then turn on the cylinder 5, allowing the cylinder 5 to drive the vacuum cleaner 4 to move downwards. When the dust suction hood 15 at the input end of the vacuum cleaner 4 approaches the tension measuring roller body 1, it can absorb the dust attached to its surface. Then, turn on the motor 16, and under the drive of the motor 16, the gear 7 will rotate, thereby driving the chain 8 to rotate. When the chain 8 rotates, it will drive the connecting column 14 set at its bottom to move together, thereby driving the first slider 13 to move, and then driving the moving plate 11 to move on the slide rod 10. The device moves back and forth. When the chain 8 rotates, the first slider 13 slides back and forth within the first groove 12 at the top of the moving plate 11. During the movement of the moving plate 11, the vacuum cleaner 4 moves along with it, allowing it to move back and forth above the tension roller body 1. Simultaneously, the tension roller body 1 rotates during operation, enabling the vacuum cleaner 4 to thoroughly clean the roller surface. When the tension roller body 1 is not used for tension testing of the steel strip, a more thorough cleaning can be performed. In this case, the electric telescopic rod 18 is opened, and the brush plate 19 moves downwards under its drive. When the brush plate 19 contacts the tension roller body 1, the motor 16 is turned on, allowing the motor to drive... The chain 8 rotates, causing the movable plate 11 to move back and forth on the slide bar 10, which in turn drives the brush plate 19 to move back and forth on the tension roller body 1. Simultaneously, in conjunction with the rotation of the tension roller body 1, the brush plate 19 can thoroughly clean the roller surface of the tension roller body 1. During the brushing process, the vacuum cleaner 4 can be turned on. The dust suction hood 15 at the input end of the vacuum cleaner 4 is located above the brush plate 19. When the vacuum cleaner 4 is turned on, it can absorb the dust generated by the brush plate 19. Once the brush plate 19 has basically cleaned away the dust and foreign objects on the tension roller body 1, it is necessary to rinse the tension roller body 1. Before rinsing, the vacuum cleaner 4 should be turned off to prevent it from absorbing the cleaning fluid and thus preventing internal contamination. Dust becomes difficult to clean when it gets wet from the cleaning fluid. The water pump 22 is then connected to a container of cleaning fluid via a water pipe. The water pump 22 is then turned on, and the cleaning fluid flows sequentially through the second connecting pipe 24, the spring water pipe 25, and the first connecting pipe 23 into the annular water pipe 20. It is then sprayed out from the nozzle 21 at the bottom of the annular water pipe 20 to rinse the tension roller body 1. During the rinsing process, the motor 16 remains on, meaning the connecting rod is rotating, causing the moving plate 11 to move back and forth on the slide rod 10. This, in turn, causes the annular water pipe 20 to move back and forth above the tension roller body 1, thus thoroughly rinsing the tension roller body 1 and cleaning it more thoroughly.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
