[0003] When releasing the wire, the reel will continue to rotate, but the reel has inertia. When the back-end equipment stops taking the wire, the reel will continue to rotate, causing the wire to be scattered around the outer periphery of the reel.

[0004] Therefore, how to prevent the wire reel from becoming disordered due to inertial rotation is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to overcome the above technical deficiencies and propose a wire unwinding device to solve the technical problem in the prior art that the wire reel causes the wire to be scattered due to inertial rotation.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem that the wire is scattered due to the inertial rotation of the wire reel, the utility model provides a wire unwinding device, which can effectively prevent the wire reel from rotating uncontrollably due to inertia.

[0026] It should be noted that the wire unwinding device of the present invention is used for but not limited to wire processing equipment, etc. For the convenience of explanation, in the present invention, only the wire unwinding device applied to wire processing equipment is used as an example for explanation, and the principle of applying the wire unwinding device to other types of equipment is essentially the same as the principle applied to wire processing equipment, which will not be repeated here.

[0027] See also Figure 1 , Figure 1 The structure diagram of the wire unwinding device in one embodiment of the utility model is shown in FIG. The wire unwinding device includes a base 100, an unwinding assembly 200 and a damping assembly 300. The unwinding assembly 200 includes a rotating seat 210 and a reel 220. The rotating seat 210 is rotatably mounted on the base 100. The reel 220 is detachably mounted on the rotating seat 210. The reel 220 is coaxially arranged with the rotating seat 210. The reel 220 is used to wind the wire. The damping assembly 300 is mounted on the base 100 and has a friction force that prevents the rotating seat 210 from rotating relative to the base 100.

[0028] In this embodiment, the reel 220 wound with the wire is first installed on the rotating seat 210. Since the rotating seat 210 is rotatably installed on the base 100, the reel 220 can rotate relative to the base 100. Pulling the wire can drive the reel 220 to rotate, and then gradually release the wire. The damping component 300 presses against the rotating seat 210. The damping component 300 has a friction force that hinders the rotation of the rotating seat 210, thereby preventing the reel 220 from rotating uncontrollably due to inertia, and thereby preventing the wire from being scattered.

[0029] In some of the embodiments, the damping assembly 300 includes a damping block 310 and an adjusting member 320. The damping block 310 is slidably disposed on the base 100. The adjusting member 320 is transmission-connected to the damping block 310, which drives the damping block 310 to approach or move away from the rotating seat 210, and can make the damping block 310 stay at any position on its sliding trajectory.

[0030] In this embodiment, the adjustment member 320 drives the damping block 310 to move closer to or away from the rotating seat 210, so that the damping block 310 presses against the rotating seat 210, and relies on the friction between the damping block 310 and the rotating seat 210 to prevent the rotating seat 210 from rotating relative to the base 100.

[0031] In some embodiments, the base 100 is provided with a screw hole 110, and the adjusting member 320 includes a screw button 321, one end of which is rotatably connected to the damping block 310, and the screw button 321 is screwed into the screw hole 110, and the damping block 310 is pushed to slide relative to the base 100 by rotating the screw button 321.

[0032] In this embodiment, since the screw button 321 is screwed into the screw hole 110 , the screw button 321 can be rotated to move along the axial direction of the screw hole 110 , thereby pushing the damping block 310 to translate, so that the damping block 310 approaches or moves away from the rotating seat 210 .

[0033] In some embodiments, the base 100 defines a guide groove 120 , and the damping block 310 is slidably disposed in the guide groove 120 .

[0034] In this embodiment, the damping block 310 slides along the guide groove 120 , so that the damping block 310 has a precise sliding track, so as to more accurately control the position of the damping block 310 .

[0035] In some embodiments, the damping block 310 includes a sliding portion 311 and a damping pad 312 . The sliding portion 311 is slidably disposed on the base 100 , and the damping pad 312 is connected to the sliding portion 311 .

[0036] In this embodiment, the sliding part 311 slides relative to the base 100, and the damping pad 312 is installed on the sliding part 311. The damping pad 312 needs to have a certain flexibility and a high friction coefficient so that the damping pad 312 contacts the rotating seat 210, and the rotation of the rotating seat 210 is limited by the friction force between the damping pad 312 and the rotating seat 210.

[0037] In some embodiments, the damping pad 312 is in an arc shape that fits the rotating base 210 .

[0038] In this embodiment, the damping pad 312 is in an arc shape, so that the damping pad 312 can fit the rotating base 210 more closely.

[0039] In some embodiments, the rotating base 210 includes a plunger portion 211 , and the reel 220 is sleeved on the plunger portion 211 .

[0040] In this embodiment, the reel 220 is sleeved on the plunger portion 211 , so that the reel 220 can be installed on the rotating base 210 more stably.

[0041] On the basis of the above embodiments, in some embodiments, the cross section of the plunger portion 211 is square, and the inner wall of the reel 220 fits the plunger portion 211 .

[0042] In this embodiment, since the plunger portion 211 is square, the reel 220 can be restricted from rotating relative to the plunger portion 211 .

[0043] In some embodiments, the unwinding assembly 200 further includes a pressure cover 230 having a first state of being connected to the end of the plunger portion 211 to prevent the roll 220 from being separated from the plunger portion 211, and a second state of being separated from the end of the plunger portion 211 to allow the roll 220 to be separated from the plunger portion 211.

[0044] In this embodiment, when the reel 220 needs to be taken out of the plunger 211, the pressure cover 230 can be adjusted to the second state, so that the pressure cover 230 can be separated from the plunger 211. When the reel 220 needs to be fixed on the plunger 211, the pressure cover 230 can be adjusted to the first state, so that the reel 220 can be pressed onto the rotating seat 210 through the pressure cover 230, thereby preventing the reel 220 from being separated from the plunger 211.

[0045] In some embodiments, an annular groove 221 for receiving the wire is formed on the outer circumference of the reel 220 .

[0046] In this embodiment, the annular groove 221 is used to accommodate the wire, thereby preventing the wire from axially detaching from the reel 220 . As the reel 220 continues to rotate, the wire in the annular groove 221 can detach from the reel 220 along the radial direction of the reel 220 .

[0047] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0048] First, the reel 220 wound with the wire is installed on the rotating seat 210. Since the rotating seat 210 is rotatably installed on the base 100, the reel 220 can rotate relative to the base 100. Pulling the wire can drive the reel 220 to rotate, and then gradually release the wire. By rotating the screw button 321, the screw button 321 can be moved along the axial direction of the screw hole 110, and then the damping block 310 can be pushed to translate, so that the damping block 310 approaches or moves away from the rotating seat 210, so that the damping block 310 presses against the rotating seat 210, and the friction between the damping block 310 and the rotating seat 210 hinders the rotating seat 210 from rotating relative to the base 100. In this way, the uncontrolled rotation of the reel 220 due to inertia can be avoided, and the scattered wires can be avoided.

[0049] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
