Description

Technical Field

[0001] The present application relates to the technical field of unwinding equipment, and in particular to a metal cotton unwinding rack. Background Art

[0002] Metal wool is a polishing material, mainly used for grinding and polishing stone products, metal products and wood products. Metal wool is usually made of low-carbon steel 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] When metal wool is processed into a product, it is usually necessary to unwind the roll of metal cotton rope formed by rough processing, and then connect the unwound metal cotton rope to the processing equipment for subsequent processing. After the metal cotton rope is directly connected to the processing equipment, as the processing equipment pulls the metal cotton rope to move continuously, the vibration amplitude of the metal cotton rope when unwinding is large, and the metal cotton rope is prone to the risk of entanglement, kinks, or even breakage. Utility Model Content

[0004] In order to improve the problem that the vibration amplitude of the metal cotton rope is large when it is unwound, and the metal cotton rope is prone to entanglement, kinking or even breakage, the present application provides a metal cotton unwinding rack.

[0005] The metal cotton unwinding rack provided in this application adopts the following technical solution:

[0006] A metal wool unwinding rack comprises a frame body, a rotating drum and a winding rod, wherein the winding rod is connected to the frame body through a fixing part, and the winding rod is used to fit a reel that winds up a metal cotton rope; the rotating drum is connected to the frame body by rotating around its own axis, and two clamping blocks are slidably connected to the peripheral wall of the rotating drum along the length direction of the rotating drum, and a gap is left between the two clamping blocks for the metal cotton rope to pass through, and a locking assembly for locking the position of the clamping block is provided on the clamping block.

[0007] By adopting the above technical scheme, when in use, the reel with the metal cotton rope wound around it is sleeved on the winding rod, and then the winding rod is connected to the frame through a fixing part, the distance between the two clamping blocks is adjusted so that only the metal cotton rope can pass through, the clamping block is locked by the locking assembly, and one end of the metal cotton rope passes through the gap between the two clamping blocks and then connected to the processing equipment for subsequent processing; the matching arrangement of the two clamping blocks and the locking assembly can guide and limit the conveying path of the metal cotton rope to a certain extent, reduce the swing amplitude of the metal cotton rope, and improve the problem that the vibration amplitude of the metal cotton rope is large when it is unwound, and it is easy to get entangled, tangled or even broken.

[0008] Optionally, a plurality of first bearings are movably sleeved on the peripheral wall of the winding rod, and the outer peripheral wall of the first bearing is adapted to the inner peripheral wall of the winding drum; an external thread is opened on the peripheral wall of the winding rod, and rotating nuts are threadedly connected on both sides of the first bearing on the peripheral wall of the winding rod.

[0009] By adopting the above technical solution, the reel with the metal cotton rope rolled up is sleeved on the outer peripheral wall of the first bearing. The setting of the first bearing allows the reel to rotate smoothly, thereby allowing the metal cotton rope to be unwound smoothly; the setting of the rotating nut makes the position of the first bearing adjustable, which is convenient for adapting to the installation requirements of reels of different lengths.

[0010] Optionally, the clamping block is annular as a whole, and the clamping block is slidably mounted on the peripheral wall of the rotating cylinder. The locking assembly includes a locking rod, which is threadedly connected to the peripheral wall of the clamping block.

[0012] Optionally, a clamping buffer block is provided on each side where the two clamping blocks are close to each other, and a buffer spring is connected between the clamping buffer blocks, and the buffer spring tends to make the two clamping buffer blocks close to each other.

[0013] By adopting the above technical solution, the setting of the clamping buffer block can protect the clamping block. The setting of the buffer spring ensures that when the metal cotton rope is clamped, the distance between the two clamping buffer blocks can still be adaptively increased or reduced according to the diameter of the metal cotton rope. It has strong adaptability, simple structure and easy use.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The present application embodiment discloses a metal wool unwinding rack. Figure 1 The steel wire unwinding device comprises a frame 1, a rotating drum 2 and a winding rod 3. The bottom of the frame 1 is provided with a self-locking universal wheel 4 for facilitating the movement of the frame 1. The top of the frame 1 is provided with a snap-fitting groove 11. The winding rod 3 is snap-fitted in the snap-fitting groove 11, and the winding rod 3 is horizontally fixedly connected to the top of the frame 1 through a fixing member 5. When in use, the reel with the metal cotton rope wound is sleeved on the winding rod 3, and the reel is not shown in the figure. The rotating drum 2 is connected to the top of the frame 1 by rotating around its own axis. The rotating drum 2 is arranged parallel to the winding rod 3. Two annular clamping blocks 6 are slidably sleeved on the outer peripheral wall of the rotating drum 2 along its own length direction. The clamping blocks 6 are provided with a locking assembly for locking the position of the clamping blocks 6.

[0030] When in use, the reel with the metal cotton rope wound around it is placed on the winding rod 3, and the reel can rotate around the winding rod 3, then the winding rod 3 is engaged in the engaging groove 11 and connected to the frame 1 through the fixing member 5; one end of the metal cotton rope is pulled out from the reel and passed through the gap between the two clamping blocks 6, the distance between the two clamping blocks 6 is adjusted so that only the metal cotton rope can pass through, the clamping blocks 6 are locked by the locking assembly, and finally the metal cotton rope is connected to the subsequent processing equipment, and the processing equipment is started to pull the metal cotton rope to unwind. The setting of the clamping block 6 can guide and limit the unwinding path of the metal cotton rope to a certain extent, reduce the swing amplitude of the metal cotton rope during the continuous unwinding process, and thus reduce the risk of the metal cotton rope being entangled, tangled, or even broken.

[0031] Exemplarily, the fixing member 5 is a butterfly nut, and an external thread 31 is provided on the peripheral wall of the winding rod 3. When the winding rod 3 is engaged in the engaging groove 11, the two butterfly nuts are respectively threadedly connected to the two ends of the winding rod 3. After tightening the butterfly nuts, the butterfly nuts are pressed against the two sides of the frame 1, so that the winding rod 3 is fixedly connected to the frame 1.

[0032] Since the reel with the metal cotton rope wound around it is usually heavy, in order to improve the smoothness of the reel rotation, two first bearings 32 are slidably mounted on the outer peripheral wall of the winding rod 3 along its own length direction. The inner diameter of the first bearing 32 is adapted to the diameter of the winding rod 3, and the outer diameter of the first bearing 32 is adapted to the inner diameter of the reel. When in use, the reel with the metal cotton rope wound around it can be directly mounted on the outer peripheral wall of the first bearing 32. The winding rod 3 is threadedly connected to both sides of the first bearing 32. By rotating the rotating nut 33, the position of the first bearing 32 can be adjusted to adapt to reels of different lengths.

[0033] The locking assembly includes a locking rod 61. For example, the locking rod 61 is a locking bolt, which is threadedly connected to the peripheral wall of the clamping block 6, and the locking bolt can be screwed into the clamping block 6 and pressed against the outer wall of the rotating cylinder 2. When the clamping block 6 is adjusted to the right position, the locking bolt is tightened until it presses against the outer wall of the rotating cylinder 2 to lock the position of the clamping block 6.

[0034] Furthermore, since the metal cotton rope is as sharp as a cutter during the process of being pulled and unwinding, in order to protect the clamping block 6 to a certain extent, a clamping buffer block 63 is connected to the side wall of the two clamping blocks 6 close to each other through a buffer spring 62, and a limit rod 64 is welded and fixed on the clamping buffer block 63, the limit rod 64 is penetrated on the clamping block 6, and the buffer spring 62 is sleeved on the limit rod 64. A gap is left between the two clamping buffer blocks 63 for the metal cotton rope to pass through, and the buffer spring 62 tends to make the two clamping buffer blocks 63 close to each other. The clamping buffer block 63 plays a protective role on the clamping block 6 and prolongs its service life; the matching arrangement of the clamping buffer block 63 and the buffer spring 62 enables the spacing between the two clamping buffer blocks 63 to be adaptively increased or reduced according to the actual diameter of the metal cotton rope on the basis of ensuring the clamping of the metal cotton rope, and has strong practicality.

[0035] In addition, in order to adapt to the feeding height required by the subsequent processing equipment of the metal cotton rope, the rotating drum 2 is rotatably connected to the top of the frame 1 through the rotating rod 21. A second bearing 211 is welded and fixed on the rotating rod 21. The rotating drum 2 is sleeved on the second bearing 211 on the rotating rod 21, so that the rotating drum 2 can smoothly rotate around the axis of the rotating rod 21. The two ends of the rotating rod 21 are rotatably connected to the two sides of the frame 1 through the rotating shaft 22. The rotating shaft 22 is parallel to the winding rod 3. The frame 1 is provided with an adjustment component for adjusting the rotation angle of the rotating shaft 22. By adjusting the rotation angle of the rotating shaft 22 through the adjustment component, the height of the rotating drum 2 can be adjusted, thereby adapting to the feeding height required by the subsequent processing equipment of the metal cotton rope.

[0036] Reference Figure 2The adjusting assembly includes a worm wheel 23 and a worm 24. The worm wheel 23 is coaxially welded and fixed on the rotating shaft 22. The worm 24 is connected to the frame by rotating around its own axis, and the worm 24 is meshed with the worm wheel 23. The end of the worm 24 is connected with a rotating handle 241. When in use, the worm 24 is driven to rotate by rotating the rotating handle 241, and the worm wheel 23 is driven to rotate, thereby driving the rotating rod 21 to rotate around the axis of the rotating shaft 22, so as to achieve the functional requirement of the adjusting assembly to adjust the rotation angle of the rotating shaft 22. And due to the transmission characteristics of the worm wheel 23 and the worm 24, that is, the worm wheel 23 can only be driven to rotate by the worm 24, and the worm 24 cannot be driven to rotate by the worm wheel 23. When the angle of the rotating shaft 22 is adjusted to a suitable angle, the rotation angle of the rotating shaft 22 can be self-locked without rotating the worm 24, so that the position of the rotating cylinder 2 is locked, and the stability is better.

[0037] The implementation principle of the wire unwinding device of the embodiment of the present application is as follows: when in use, the reel with the metal cotton rope is mounted on the first bearing 32 on the winding rod 3, and then the winding rod 3 is engaged in the engaging groove 11 on the top of the frame and the winding rod 3 is locked with the frame by a locking piece; then according to the feeding height required by the subsequent processing equipment, the rotating handle 241 is rotated to drive the worm 24 to rotate, and the worm wheel 23 is driven to rotate until the height of the rotating drum 2 is consistent with the feeding height required by the subsequent processing equipment, and then the distance between the two clamping blocks 6 is adjusted until the metal cotton rope drawn from the reel can pass through the distance between the two clamping buffer blocks 63, and the two clamping buffer blocks 63 clamp the metal cotton rope, at this time, the position of the clamping block 6 is locked by the locking rod 61, and finally the metal cotton rope is connected to the subsequent processing equipment. The arrangement of the clamping block 6, the clamping buffer block 63 and the buffer spring 62 can clamp the metal cotton rope, play a certain degree of guiding and limiting role on the conveying path of the metal cotton rope, reduce the swing amplitude of the metal cotton rope, and improve the risk of the metal cotton rope being easily entangled, kinked or even broken when unwinding.

[0038] 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.
