Description

Technical Field

[0001] The utility model mainly relates to the technical field of wire-releasing devices, in particular to a wire-reel unwinder. Background Art

[0002] In order to facilitate storage and transportation, wire manufacturers often wind the wire into coils (that is, wind the wire into various packages according to a certain pattern). When the wire is to be used, the operator releases the wire from the reel by pulling it.

[0003] In actual operation, if the wire is extracted from the side, friction will occur between the wires, and this friction can easily lead to uneven wire release speed, causing the wire to be entangled and knotted, thus affecting subsequent production.

[0004] Therefore, there is a need for a wire reel pay-off device suitable for a wire reel that can reduce friction between wires and thus reduce the probability of entanglement. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a wire reel unwinder.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A wire reel pay-off device comprises: a wire drum for winding a wire; a rotating shaft, which is coaxially arranged with the wire drum and rotatably connected to the wire drum; a wire pay-off rod, which is perpendicular to the rotating shaft, one end of the wire pay-off rod is connected to the rotating shaft, and the other end of the wire pay-off rod is provided with a threading ring, and the threading ring is used for allowing the wire on the wire drum to pass through; wherein, the rotating shaft is used to drive the wire pay-off rod to rotate relative to the wire drum when the wire on the wire drum is paid off.

[0008] As a further improvement of the above technical solution:

[0009] It also includes a connecting sleeve, which is detachably mounted on the wire reel, and the rotating shaft is rotatably connected to the connecting sleeve, and the rotating shaft can drive the wire-releasing rod to rotate relative to the connecting sleeve.

[0010] One end of the wire barrel is provided with a connecting hole, and the connecting sleeve is inserted into the connecting hole.

[0011] The connecting sleeve comprises a connecting portion and a limiting portion connected to each other, the connecting portion has a diameter smaller than that of the limiting portion, the connecting portion is inserted into the connecting hole, and the limiting portion abuts against the wire barrel at one end thereof facing the connecting portion.

[0012] The limiting portion includes a first limiting portion and a second limiting portion, wherein the second limiting portion is connected between the first limiting portion and the connecting portion, the second limiting portion is provided with a first end toward the first limiting portion, and the second limiting portion is provided with a second end toward the connecting portion;

[0013] The diameter of the second limiting portion decreases gradually from the first end toward the second end, and the second limiting portion is at least partially disposed in the connecting hole.

[0014] It also includes a bearing, which is arranged between the connecting sleeve and the rotating shaft.

[0015] The connecting sleeve is provided with a through hole along the axial direction, the bearing is arranged in the through hole, and the bearing sleeve is arranged on the rotating shaft.

[0016] The number of the bearings is at least two, and at least two of the bearings are arranged in the through hole at intervals along the axial direction of the connecting sleeve.

[0017] It also includes an outer cover, in which the bobbin, the rotating shaft and the wire-releasing rod are all accommodated.

[0018] The outer cover is provided with a wiring hole, and the wiring hole is used for the wire on the threading ring to pass through.

[0019] Compared with the prior art, the advantages of the utility model are:

When the external mechanism pulls the wire, the wire rotates around the bobbin to release it. At this time, the wire will push the threading ring to rotate synchronously. Since the threading ring protrudes radially from the bobbin, friction between the wires can be reduced, thereby reducing the probability of entanglement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 3 As shown, the wire reel and unwinder of this embodiment comprises: a wire drum 1, a rotating shaft 2 and a wire unwinding rod 3, wherein the rotating shaft 2 is respectively connected to the wire drum 1 and the wire unwinding rod 3. The wire drum 1 is used for winding wire, the rotating shaft 2 is coaxially arranged with the wire drum 1, and the rotating shaft 2 is rotatably connected to the wire drum 1; the wire unwinding rod 3 is perpendicular to the rotating shaft 2, one end of the wire unwinding rod 3 is connected to the rotating shaft 2, and the other end of the wire unwinding rod 3 is provided with a threading ring 31, and the threading ring 31 is used for the wire on the wire drum 1 to pass through. When the rotating shaft 2 is used to unwind the wire on the wire drum 1, it drives the wire unwinding rod 3 to rotate relative to the wire drum 1, and drives the wire to rotate around the wire drum 1 through the threading ring 31.

[0027] The wire drum 1 includes a barrel 11, a first baffle 12 and a second baffle 13. The first baffle 12 and the second baffle 13 are respectively connected to two opposite ends of the barrel 11 in the axial direction, and the diameters of the first baffle 12 and the second baffle 13 are both larger than the diameters of the barrel 11. The barrel 11 is used for winding the wire, and the first baffle 12 and the second baffle 13 are used to prevent the wire from escaping from the barrel. The rotating shaft 2 is connected to one end of the barrel 11 facing the first baffle 12, and the second baffle 13 is also used to support the barrel 11.

[0028] The rotating shaft 2 is rod-shaped and coaxially arranged with the barrel 11 of the bobbin 1 . One end of the rotating shaft 2 is rotatably inserted into the barrel 1 , and the other end of the rotating shaft 2 protrudes axially from the bobbin 1 . The other end of the rotating shaft 2 is fixedly connected to the pay-off rod 3 .

[0029] The wire-releasing rod 3 is configured as a rod-shaped structure, and the wire-preventing rod 3 is perpendicular to the rotating shaft 2. The length of the wire-releasing rod 3 is greater than the radius of the first baffle 12 of the wire drum 1, that is, one end of the wire-releasing rod 3 provided with a threading ring 31 protrudes from the first baffle 12 in the radial direction of the wire drum 1. The wire wound on the cylinder 11 passes through the threading ring 31 and is connected to the external mechanism. When the external mechanism pulls the wire, the wire rotates around the wire drum 1 to be released. At this time, the wire will drive the threading ring 31 to rotate. Since the threading ring 31 protrudes from the first baffle 12 of the wire drum 1 in the radial direction of the wire drum 1, the friction between the wire and the wire drum 1 can be reduced, thereby avoiding the entanglement of the wire.

[0030] Furthermore, the wire reel unwinder also includes a connecting sleeve 4, which is detachably mounted on the wire drum 1, and the rotating shaft 2 is rotatably connected to the connecting sleeve 4, and the rotating shaft 2 can drive the unwinding rod 3 to rotate relative to the connecting sleeve 4. A connecting hole 111 is provided at one end of the wire drum 1, and the connecting sleeve 4 is inserted into the connecting hole 111. The barrel 11 of the wire drum 1 in the prior art is usually formed with a through-type connecting hole 111 along the central axis. The present application provides a connecting sleeve 4, which is inserted into the connecting hole 111 from one end of the wire drum 1 to form a stable connection. This connection method is simple and convenient, and will not cause damage to the wire drum 1. After the connecting sleeve 4 is connected to the wire drum 1, it can provide support for the unwinding rod 3 and the threading ring 31.

[0031] In this embodiment, the connecting sleeve 4 includes a connecting portion 41 and a limiting portion 42 connected to each other. The connecting portion 41 and the limiting portion 42 are both configured as an annular structure and are coaxially connected. The diameter of the connecting portion 41 is smaller than the diameter of the limiting portion 42. The connecting portion 41 is inserted into the connecting hole 111, and the limiting portion 42 abuts against the wire barrel 1 at one end of the connecting portion 41, thereby being able to control the depth of the connecting portion inserted into the wire barrel 1.

[0032] The limiting portion 42 includes a first limiting portion 421 and a second limiting portion 422, and the second limiting portion 422 is connected between the first limiting portion 421 and the connecting portion 41. The second limiting portion 422 is provided with a first end toward the first limiting portion 421, and the second limiting portion 422 is provided with a second end toward the connecting portion 41. The outer diameter of the second limiting portion 422 decreases in sequence from the first end toward the second end, and the second limiting portion 422 is at least partially disposed in the connecting hole 111, so that the connecting sleeve 4 is firmly connected to the wire drum 1. By providing the second limiting portion 422 with a variable cross-section, the connecting sleeve 4 can be connected to wire drums 1 of more sizes, thereby expanding the adaptability range of the wire reel and unwinder.

[0033] Furthermore, the wire reel and unwinder further comprises a bearing 5, which is arranged between the connecting sleeve 4 and the rotating shaft 2. The connecting sleeve 4 is provided with a through hole 43 along the axial direction, the bearing 5 is arranged in the through hole 43, and the bearing 5 is sleeved on the rotating shaft 2. By providing the bearing 5, the relative rotation of the rotating shaft 2 and the connecting sleeve 4 is smoother.

[0034] In this embodiment, the number of bearings 5 ​​is two, and the two bearings 5 ​​are spaced apart in the through hole 43 along the axial direction of the connecting sleeve 4. The two bearings 5 ​​are respectively installed at both ends of the through hole 43, and the two bearings 5 ​​are respectively connected to the two ends of the rotating shaft 2, so that the force can be optimized and the radial swing of the rotating shaft 2 during the rotation process can be avoided or reduced. It can be understood that in some other embodiments, the number of bearings 5 ​​can be set according to actual needs, such as one, three, four, etc., which is not limited here.

[0035] Furthermore, the wire reel and unwinder also includes an outer cover 6, and the wire drum 1, the rotating shaft 2 and the unwinding rod 3 are all accommodated in the outer cover 6. The outer cover 6 is a cylindrical shell with one end open, and is made of a transparent material so that the unwinding condition inside it can be observed. The outer cover 6 is provided with a wire routing hole 61, which is arranged at the closed end of the outer cover 6, and the wire routing hole 61 is used for the wire on the threading ring 31 to pass through. By providing the outer cover 6, the wire drum 1, the rotating shaft 2, the unwinding rod 3 and the wire wound on the wire drum 1 can be protected. At the same time, in order to facilitate the passing of the wire, the wire routing hole 61 is opened on the outer cover 6. The wire wound on the wire drum 1 passes through the threading ring 31 and then passes through the outer cover 6 from the wire routing hole 61, and then is connected to the external mechanism.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
