Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of traction devices, in particular to a traction mechanism used for steel fiber production. Background Art
[0002] Steel fiber is a new type of building material with many excellent properties. Its main function is to enhance the performance of building materials such as concrete. It can significantly improve the tensile, flexural and impact strength of concrete, and effectively improve the toughness and crack resistance of concrete. Therefore, the demand is high. In the production process of steel fiber, it needs to be pulled, wound or cut. However, during the pulling process, only steel fibers of fixed sizes can be pulled according to the constant distance between the pulling rollers. If steel fibers of other sizes are to be pulled, the pulling rollers need to be replaced or adjusted, which has low work efficiency, increased costs, and low practical performance. Therefore, it is necessary to design a steel fiber that can pull different sizes to reduce costs.
[0003] The existing traction mechanism can only pull steel fibers of a set size during use. If the size of the steel fiber changes, the steel fiber cannot be pulled due to low pressure, while high pressure will damage the steel fiber and increase losses. The practical performance of the device is not high.
[0004] Therefore, in order to solve the above problems, a traction mechanism for steel fiber production is proposed. Utility Model Content
[0005] In order to solve the problems raised in the above background technology, the utility model provides a traction mechanism for steel fiber production, which has the advantage of being able to traction steel fibers of different sizes.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a traction mechanism for steel fiber production, comprising a first support plate, a first rotating shaft inserted and connected to the upper part of the first support plate, a first roller sleeved on the outer side of the first rotating shaft, a connecting column fixedly connected to the top end of the first rotating shaft, a second support plate fixedly connected to the top end of the connecting column, a sliding groove provided inside the second support plate, a second rotating shaft rotatably connected inside the sliding groove, a second roller sleeved on the outer side of the second rotating shaft, sliders rotatably connected to both ends of the second rotating shaft, and a spring fixedly connected to the top end of the slider.
[0007] Preferably, an adjusting sleeve is spirally connected to the outer side of the second rotating shaft, a bolt is embedded in the adjusting sleeve, and the outer side of the adjusting sleeve is in contact with the inner wall of the second roller, and a limiting groove is provided on one side of the second roller.
[0008] Preferably, one end of the first rotating shaft is fixedly connected to a servo motor, and the servo motor is fixed on the outside of the first supporting plate.
[0009] Preferably, a support seat is sleeved on the outer side of the first rotating shaft, a bearing is embedded in the interior of the support seat, and the bearing is sleeved on the outer side of the first rotating shaft.
[0010] Preferably, the bottom end of the servo motor is fixedly connected to a support base, and a hydraulic rod is embedded in the interior of the support base.
[0011] Preferably, a lifting plate is fitted on the top of the hydraulic rod, a polished rod is inserted into the interior of the lifting plate, the top of the polished rod is fixedly connected to the bottom end of the first support plate, and the lower part of the polished rod is embedded in the interior of the support base.
[0012] Preferably, a brake wheel is fixedly connected to the bottom end of the support base, and there are four brake wheels, which are arranged at the four corners of the bottom surface of the support base.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0014] 1. The utility model provides a spring. When steel fiber needs to be produced and produced, one end of the steel fiber is clamped between the first roller and the second roller, and the first rotating shaft connected to the upper part of the first support plate is rotated. The first rotating shaft drives the first roller sleeved on the outside to rotate, and drives the steel fiber to move and pull it. If the size of the steel fiber changes, the steel fiber applies pressure to the second roller, and the second roller drives the second rotating shaft to move. The second rotating shaft pushes the slider to slide inside the slide groove opened inside the second support plate, changing the distance between the first roller and the second roller, thereby realizing the traction of steel fibers of different sizes. Under the action of the spring, pressure is applied to the slider, so that the first roller can apply pressure to the steel fiber, and the steel fiber will not be pulled normally due to too little pressure, and the steel fiber can be prevented from being damaged by excessive pressure, thereby reducing economic losses.
[0015] 2. The utility model sets an adjusting sleeve to put the steel fiber into the inside of the limiting groove, which can prevent the steel fiber from shifting when the steel fiber is pulled. If the size of the limiting groove is not conducive to pulling the steel fiber, the bolt embedded in the adjusting sleeve is pulled out, and the adjusting sleeve is rotated to drive the second roller set on the outside to move, and the limiting groove is adjusted to an appropriate size. It is convenient and quick, and there is no need to replace special rollers, and the performance is high. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figures 1 to 5 As shown, the utility model provides a traction mechanism for steel fiber production, including a first support plate 1, a first rotating shaft 2 is inserted and connected on the upper part of the first support plate 1, a first roller 3 is sleeved on the outer side of the first rotating shaft 2, the top end of the first rotating shaft 2 is fixedly connected to a connecting column 4, the top end of the connecting column 4 is fixedly connected to the second support plate 5, a slide groove 6 is opened inside the second support plate 5, the inside of the slide groove 6 is rotatably connected to the second rotating shaft 7, a second roller 8 is sleeved on the outer side of the second rotating shaft 7, sliders 9 are rotatably connected at both ends of the second rotating shaft 7, and a spring 10 is fixedly connected to the top of the slider 9. Under the action of the spring 10, pressure will be applied to the slider 9, so that the first roller 3 can apply pressure to the steel fiber, so that the steel fiber will not be pulled normally due to too little pressure, and the steel fiber can be prevented from being damaged by excessive pressure, thereby reducing economic losses.
[0024] Specifically, the outer side of the second rotating shaft 7 is spirally connected with an adjusting sleeve 11, the interior of the adjusting sleeve 11 is embedded with a bolt 12, and the outer side of the adjusting sleeve 11 is in contact with the inner wall of the second roller 8. A limiting groove 13 is provided on one side of the second roller 8. When the steel fiber is placed into the limiting groove 13, the steel fiber can be prevented from being offset when it is pulled.
[0025] Furthermore, one end of the first rotating shaft 2 is fixedly connected to a servo motor 14, and the servo motor 14 is fixed on the outside of the first supporting plate 1, so that the staff does not need to manually rotate the device, which reduces the labor intensity of the staff and improves work efficiency.
[0026] Furthermore, a support seat 15 is provided on the outer side of the first rotating shaft 2, and a bearing 16 is embedded in the interior of the support seat 15, and the bearing 16 is provided on the outer side of the first rotating shaft 2. Under the action of the bearing 16, the friction coefficient between the first rotating shaft 2 and the support seat 15 can be reduced, thereby ensuring the rotation accuracy of the first rotating shaft 2 and reducing energy consumption.
[0027] It is worth noting that the bottom end of the servo motor 14 is fixedly connected to a support base 17 , and a hydraulic rod 18 is embedded inside the support base 17 to facilitate the staff to adjust the height of the device to cooperate with subsequent processes.
[0028] It is worth noting that a lifting plate 19 is fitted on the top of the hydraulic rod 18, and a light rod 20 is inserted into the interior of the lifting plate 19, and the top of the light rod 20 is fixedly connected to the bottom end of the first support plate 1, and the lower part of the light rod 20 is embedded in the interior of the support base 17. Under the action of the light rod 20, the lifting plate 19 can be guided to prevent it from shifting during movement and increase stability.
[0029] It is worth mentioning that the bottom end of the support base 17 is fixedly connected to a brake wheel 21, and there are four brake wheels 21, which are arranged at the four corners of the bottom surface of the support base 17.

Under the action of the brake wheel 21, the labor intensity of the staff is reduced, the device can be quickly moved and fixed, and the hydraulic rod 18 embedded in the support base 17 is started to push the lifting plate 19 to move the first support plate 1 to a suitable position. Under the action of the light rod 20, the lifting plate 19 can be guided to prevent it from deflecting during the movement and increase stability. The staff first clamps one end of the steel fiber to the inside of the limit groove 13 between the first roller 3 and the second roller 8, starts the servo motor 14, and drives the first rotating shaft 2 connected to the upper part of the first support plate 1 to rotate. Under the action of the bearing 16, the friction coefficient between the first rotating shaft 2 and the support seat 15 can be reduced to ensure the rotation accuracy of the first rotating shaft 2 and reduce energy consumption. The first rotating shaft 2 drives the first roller 3 sleeved on the outside to rotate, and drives the steel fiber to move and pull it. If the size of the steel fiber changes When the steel fiber is put into the limiting groove 13, the steel fiber can be prevented from deflecting when the steel fiber is being pulled. If the size of the limiting groove 13 is not conducive to the traction of the steel fiber, the bolt 12 embedded in the adjusting sleeve 11 is pulled out, and the adjusting sleeve 11 is rotated to drive the second roller 8 set on the outside to move, and the limiting groove 13 is adjusted to an appropriate size. It is convenient and fast, and there is no need to replace special rollers, and the performance is high.
