Description

Technical Field

[0001] The present application relates to the technical field of steel wire unwinding, and in particular to a steel wire unwinding device. Background Art

[0002] Steel wool is a polishing material, mainly used for grinding and polishing stone products, metal products and wood products. Steel wool is made of low-carbon steel into filaments with a diameter of 0.125mm to 0.189mm. It has good softness and better wear resistance than cotton and linen fibers. It has grinding and polishing properties and can replace sandpaper and emery cloth for grinding and polishing the surface of wood products, metal products, decoration projects, etc.

[0003] Steel wool is usually made from cold-rolled steel wire through steel wool processing equipment. The cold-rolled steel wire is generally transported to the steel wool processing equipment through a wire unwinding device. The wire unwinding device proposed in the relevant technology includes a turntable. When in use, the wire roll is placed on the turntable, and one end of the steel wire in the wire roll is connected to the steel wool processing equipment. The steel wire is pulled by the steel wool processing equipment and then the turntable is rotated to realize the unwinding operation of the wire roll.

[0004] For the above-mentioned related technologies, the wire roll is heavy, resulting in a large rotational inertia when the turntable rotates. When there is no need to unwind the wire, the turntable will still rotate due to inertia, causing the wire to be in a relaxed state, affecting the control of the wire tension and the unwinding quality. Utility Model Content

[0005] In order to improve the problem of unwinding quality affected by unwinding through a turntable, the present application provides a steel wire unwinding device.

[0006] The present application provides a steel wire unwinding device that adopts the following technical solution:

[0007] A wire unwinding device comprises a fixed base and a wire pay-off frame, wherein the fixed base is used to support the wire roll, the wire pay-off frame is arranged on one side of the fixed base, and the wire pay-off frame is provided with a wire guide tensioning mechanism, and the wire guide tensioning mechanism is used to guide and adjust the tension of the passing wire.

[0008] By adopting the above technical scheme, when in use, the steel wire roll is directly placed on the fixed base, and then one end of the steel wire in the steel wire roll is passed through the steel wire guide tensioning mechanism, and then the end of the steel wire is connected to the steel wool processing equipment, and the steel wire is unwound by the pulling force of the steel wool processing equipment on the steel wire, and the steel wire is guided and tensioned when passing through the steel wire guide tensioning mechanism; the steel wire roll itself does not rotate, and the steel wire is guided and tensioned by the steel wire guide tensioning mechanism, so the steel wire is not easy to be entangled and loose, and the tension can be controlled, thereby improving the problem of unwinding by unwinding through a turntable affecting the unwinding quality.

[0009] Optionally, a center limit rod is vertically provided in the middle of the fixed base, and the wire guide tensioning mechanism includes a guide assembly and a tensioning assembly, the guide assembly includes a guide arm, one end of the guide arm is vertically rotatable and connected to the wire pay-off frame, and the other end of the guide arm is provided with a threading barrel for the wire to pass through, and the tensioning assembly is used to adjust the tension of the wire.

[0010] By adopting the above technical solution, after the wire roll is placed on the fixed base, the center limit rod passes through the center of the wire roll to limit the wire roll, thereby reducing the probability of the wire roll moving and becoming loose when unwinding; when in use, the fixed base is moved until the axis of the center limit rod coincides with the axis of the guide arm, and one end of the steel wire in the wire roll passes through the threading barrel and then through the tensioning assembly. During the pulling process, the steel wire will cause the guide arm to rotate around the axis of the center limit rod, thereby guiding the unwinding of the steel wire and reducing the probability of the steel wire being entangled and kinked; the tensioning assembly adjusts the tightness of the passed steel wire to improve the unwinding quality of the steel wire.

[0011] Optionally, the guide arm includes a fixed arm and a movable arm, one end of the fixed arm is connected to the wire pay-off frame for vertical rotation, and the fixed arm is provided with two threaded columns at intervals along its own length direction; the movable arm is provided with a waist-shaped through groove corresponding to the threaded column, and the two threaded columns are both inserted into the waist-shaped through groove, and a locking nut is threadedly connected to the threaded column, and the wire threading tube is provided at one end of the movable arm away from the fixed arm.

[0012] By adopting the above technical solution, when in use, the movable arm can be slidably fixed along the length direction of the fixed arm through the setting of the waist-shaped through groove, so as to adapt to different heights and diameters of the wire roll, so that the guide arm has a better guiding effect on the steel wire in the wire roll.

[0013] Optionally, the tensioning assembly includes a fixed pulley and a movable pulley for sequentially winding the steel wire, the fixed pulley is fixedly mounted on a pay-off frame, the movable pulley is slidably connected to the pay-off frame in a direction approaching or moving away from the fixed pulley, and the pay-off frame is provided with an adjustment component for automatically adjusting the distance between the fixed pulley and the movable pulley.

[0016] By adopting the above technical solution, the steel wool processing equipment can pull the steel wire to make the movable pulley overcome the elastic force of the compression spring and move a distance toward the fixed pulley. The position of the movable pulley maintains dynamic balance under the joint action of the steel wire tension and the elastic force of the compression spring.

[0021] Optionally, universal wheels are provided at the bottom of the fixed base.

[0022] By adopting the above technical solution, the setting of the universal wheel can facilitate the movement of the fixed base on which the wire roll is placed, saving time and effort.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The present application embodiment discloses a steel wire unwinding device. Figure 1The steel wire unwinding device comprises a fixed base 1 and a pay-off frame 2. The fixed base 1 is used to support and position the steel wire coil placed thereon. The pay-off frame 2 is fixedly installed on one side of the fixed base 1. The pay-off frame 2 is provided with a steel wire guide and tension mechanism 3. One end of the steel wire in the steel wire coil passes through the steel wire guide and tension mechanism 3 and then is connected to the steel wool processing equipment. The steel wool processing equipment is not shown in the figure. The steel wire guide and tension mechanism 3 is used to guide and tension the passing steel wire.

[0033] The fixed base 1 includes a base frame 11, a center limit rod 12, an edge limit rod 13 and a universal wheel 14. The base frame 11 is fixed by two horizontal plates 111 that are welded vertically to each other. The center limit rod 12 is welded and fixed to the center of the base frame 11 along the vertical direction. The center limit rod 12 includes four vertical rods 121. The four vertical rods 121 are evenly distributed around the center of the base frame 11 along the vertical direction. When placing the wire roll, the wire roll is directly placed on the upper surface of the horizontal plate 111, wherein the inner ring of the wire roll is sleeved outside the center limit rod 12. The center limit rod 12 can limit the movement of the wire roll. The edge limit rod 13 is welded and fixed to the two ends of each horizontal plate 111 along the vertical direction. The setting of the edge limit rod 13 can limit the outer edge of the wire roll and prevent the wire from being directly loosened when unwinding. The universal wheel 14 is a self-locking universal wheel 14 , and the universal wheel 14 is installed at the bottom of the base frame 11 . The setting of the universal wheel 14 enables the fixed base 1 to move more conveniently.

[0034] In addition, in order to further reduce the probability of the wire roll becoming loose during the unwinding process, a counterweight 15 is provided on the fixed base 1. After the wire roll is placed on the fixed base 1, the counterweight 15 is covered on the wire roll. The wire roll can be continuously pressurized during the continuous unwinding process, thereby reducing the probability of the wire roll becoming loose.

[0035] The pay-off frame 2 includes a crossbeam 21 and a vertical rod 22. The vertical rod 22 is vertically fixedly installed on the ground on one side of the fixed base 1, and the crossbeam 21 is horizontally welded and fixed to the top of the vertical rod 22. The wire guide tensioning mechanism 3 includes a guide assembly 31 and a tensioning assembly 32. The guide assembly 31 is used to guide the wire output from the wire coil, and the tensioning assembly 32 is used to adjust the tension of the wire.

[0036] Reference Figure 1-2The guide assembly 31 includes a guide arm, which includes a fixed arm 311 and a movable arm 312. A hollow shaft 211 is vertically arranged at one end of the cross beam 21 away from the vertical rod 22. One end of the fixed arm 311 is rotatably connected to the outer peripheral wall of the hollow shaft 211 through a bearing 212. The fixed arm 311 is arranged downward at a 30° depression angle. Two threaded columns 3111 are arranged at intervals along the length direction of the fixed arm 311. A waist-shaped through groove 3121 is opened on the movable arm 312 along the length direction of the movable arm 312 corresponding to the threaded columns 3111. Both threaded columns 3111 are inserted into the waist-shaped through groove 3121. A locking nut 3112 is threadedly connected to the threaded column 3111. Tightening the locking nut 3112 can press and fix the movable arm 312 on the fixed arm 311. A threading barrel 313 is welded and fixed to one end of the movable arm 312 away from the fixed arm 311 , and an anti-wear pad 314 is provided on the inner wall of the threading barrel 313 . The anti-wear pad 314 is used to protect the threading barrel 313 and extend the service life of the threading barrel 313 .

[0037] When in use, the position of the fixed base 1 is adjusted so that the center of the fixed base 1 coincides with the axis of the hollow shaft 211. After one end of the steel wire in the steel wire roll passes through the threading barrel 313, it passes through the hollow shaft 211, and then passes the steel wire through the elastic component 32, and finally connects the steel wire to the steel wool processing equipment. In the process of pulling the steel wire, the steel wool processing equipment drives the fixed arm 311 to rotate around the hollow shaft 211, so as to pull the steel wire out of the steel wire roll. The setting of the fixed arm 311 and the threading barrel 313 guides the steel wire, reducing the probability of the steel wire being entangled and tangled when unwinding. The setting of the threaded column 3111, the locking nut 3112 and the waist-shaped through groove 3121 enables the movable arm 312 to be adjusted along the length direction of the fixed arm 311, so as to adapt to steel wire rolls of different heights and diameters, making the guidance more accurate.

[0038] Reference Figure 1 The tensioning assembly 32 includes a fixed pulley 321 and a movable pulley 322. Three groups of fixed pulleys 321 are arranged at intervals along the length direction of the crossbeam 21. The movable pulley 322 is vertically slidably connected to the vertical rod 22. The vertical rod 22 is provided with an adjustment component for automatically adjusting the height of the movable pulley 322. The steel wire passing through the hollow shaft 211 is sequentially wound on the three fixed pulleys 321 from close to the hollow shaft 211 to away from the hollow shaft 211, and then the steel wire passes downward through the movable pulley 322 and is wound on the movable pulley 322, and then the steel wire is connected to the steel wool processing equipment.

[0039] The adjustment component includes a guide rod 323 and a compression spring 324. Two guide rods 323 are arranged in parallel. The two guide rods 323 are fixedly mounted on the vertical rod 22 through a mounting plate 325 in the vertical direction. The two guide rods 323 are both passed through the movable pulley 322, and the movable pulley 322 is located below the mounting plate 325. The compression spring 324 is sleeved on one of the guide rods 323. One end of the compression spring 324 is welded and fixed to the mounting plate 325, and the other end of the compression spring 324 is welded and fixed to the movable pulley 322. The compression spring 324 tends to make the movable pulley 322 slide downward away from the mounting plate 325.

[0040] When in use, the steel wool processing equipment works to pull the steel wire to unwind. When the instantaneous rate at which the steel wool processing equipment pulls the steel wire changes, the pulling force on the steel wire will change, and the tightness of the steel wire will change, affecting the quality of steel wire unwinding. The setting of the compression spring 324 can compensate for the magnitude of the force on the steel wire, that is, when the force on the steel wire increases, the movable pulley 322 is forced to overcome the elastic force of the compression spring 324 and move upward, thereby balancing the force on the steel wire; when the force on the steel wire decreases, the movable pulley 322 is moved downward by the elastic force of the compression spring 324, thereby balancing the force on the steel wire, and then adaptively adjusting the tightness of the steel wire to improve the quality of steel wire unwinding.

[0041] The implementation principle of the steel wire unwinding device of the embodiment of the present application is as follows: when in use, the steel wire roll is directly placed on the fixed base 1, and the steel wire roll is limited by the central limiting rod 12, the edge limiting rod 13 and the counterweight 15; then one end of the steel wire in the steel wire roll is passed through the threading barrel 313 at the end of the movable arm 312, and then passed through the hollow rotating shaft 211, and then the steel wire is sequentially wound on the fixed pulley 321 and the movable pulley 322, and finally the steel wire is connected to the steel wool processing equipment. The steel wool processing equipment drives the steel wire to be pulled to realize the unwinding of the steel wire, and the pulling of the steel wire drives the guide arm to rotate around the hollow rotating shaft 211, thereby guiding the unwinding of the steel wire and reducing the probability of the steel wire being entangled and kinked during unwinding; the setting of the compression spring 324 can compensate and adjust the instantaneous force of the steel wire, so that the force of the steel wire is balanced, and then the tightness of the steel wire is adaptively adjusted to improve the quality of the steel wire unwinding.

[0042] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
