Description

Technical Field

[0001] This utility model relates to the field of copper wire unwinding technology, specifically to an automatic wire unwinding and self-locking device for copper wire. Background Technology

[0002] Copper wire, as an important raw material, is commonly used in the production and processing of various copper wires, cables, and decorative alloy wires. Due to its relatively low hardness, copper wire requires protection by reels during transportation and storage to prevent surface scratches and damage. When using copper wire as a raw material in production, the reels are placed horizontally on the ground for unwinding before being fed into the production line. The copper wire is unwound one turn after another around the reel. During this unwinding process, the copper wire is easily scratched by the edge of the reel, affecting not only its appearance but also its tensile strength, thus impacting product quality and causing production inconvenience. Therefore, an automatic wire-reaming and self-locking unwinding device was designed to prevent copper wire scratches. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic wire unwinding and self-locking device for copper wire, which solves the problem of copper wire easily rubbing against the wire reel during unwinding, causing defects.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An automatic wire unwinding and self-locking device for copper wire includes a positioning post inserted into the center hole of a flat spool wound with copper wire. A spring telescopic rod is installed radially on the side wall of the positioning post, and a vertical support roller is installed at the end of the spring telescopic rod and is in rolling connection with the inner wall of the center hole of the spool.

[0006] A fixing rod is vertically fixed to the top of the positioning column. A turntable is rotatably connected to the surface of the fixing rod via a bushing. A support rod is horizontally fixed on the turntable. A limiting sleeve for inserting copper wire onto the reel is fixed to one end of the support rod. A balance bolt is installed at the other end of the support rod.

[0007] A telescopic fork is vertically mounted on the top of the positioning column on one side of the fixed rod. A support spring is installed inside the positioning column at the lower end of the telescopic fork. A positioning roller is installed at the upper end of the telescopic fork. A positioning groove with a wavy top is provided on the lower surface of the turntable at the position corresponding to the positioning roller.

[0008] Preferably, the adjusting bolt installed vertically at the bottom of the positioning post is a star bolt.

[0009] Preferably, there are multiple sets of spring telescopic rods and support rollers, which are equidistant from each other along the circumference and axial direction of the positioning post.

[0010] Preferably, the support roller is a non-slip rubber-coated roller.

[0011] Preferably, a straight handle is fixed to the top of the fixing rod.

[0012] Preferably, the limiting sleeve is a cylinder with both the upper and lower end diameters larger than the middle inner diameter, and the upper and lower ends of the limiting sleeve have smooth rounded corners with the inner and outer walls.

[0013] Preferably, a connecting seat is vertically fixed to one end of the support rod corresponding to the balance bolt, and the balance bolt is horizontally threaded onto the connecting seat.

[0014] Preferably, the balance bolt and the support rod are located in the same vertical plane, and the balance bolt is a star bolt.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a positioning post installed in the center hole of the wire reel. The fixed rod on the positioning post has a rotatable turntable. A limiting sleeve with smooth, rounded corners at both the upper and lower ends of the support rod is used to insert and support the unwound copper wire, preventing scratches between the unwound copper wire and the edge of the reel and thus achieving automatic wire management. Furthermore, during unwinding, the copper wire drives the turntable and support rod to rotate. When production lines are frequently paused, a positioning roller elastically supported in the positioning groove provides elastic positioning to the turntable, preventing it from continuing to rotate due to inertia and causing excessive unwinding and tangling of the copper wire during production stoppages. The positioning roller and positioning groove achieve a self-locking effect on the turntable, providing convenience and improving production efficiency. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-8 As shown, this utility model provides a technical solution: an automatic wire unwinding and self-locking device for copper wire, including a positioning post 3 inserted into the center hole of a wire spool 2 with copper wire 1 wound on a flat surface, and an adjusting bolt 16 with a vertical thread installed at the bottom of the positioning post 3. The adjusting bolt 16 is a Torx bolt, which is convenient to adjust the height to adapt to different wire spools 2.

[0028] A spring telescopic rod 4 is installed radially on the side wall of the positioning column 3. A vertical support roller 5 is installed at the end of the spring telescopic rod 4 and is rolledly connected to the inner wall of the center hole of the coil 2. The support roller 5 is a non-slip rubber-coated roller. There are multiple sets of spring telescopic rods 4 and support rollers 5, which are equidistantly arranged along the circumference and axial direction of the positioning column 3.

[0029] A fixing rod 6 is vertically fixed to the top of the positioning post 3. A straight handle 17 is fixed to the top of the fixing rod 6. A turntable 8 is rotatably connected to the surface of the fixing rod 6 through a bushing 7. A support rod 9 is horizontally fixed on the turntable 8. A limiting sleeve 10 for threading copper wire 1 onto the wire reel 2 is fixed to one end of the support rod 9. The limiting sleeve 10 is a cylinder with the upper and lower end diameters larger than the middle inner diameter. The upper and lower ends of the limiting sleeve 10 have smooth rounded corners with the inner and outer walls.

[0030] The other end of the support rod 9 is equipped with a balance bolt 11. The end of the support rod 9 corresponding to the balance bolt 11 is vertically fixed with a connecting seat 18. The balance bolt 11 is horizontally threaded on the connecting seat 18. The balance bolt 11 and the support rod 9 are located in the same vertical plane. The balance bolt 11 is a Torx bolt.

[0031] The top of the positioning column 3 is vertically mounted on one side of the fixed rod 6 with a telescopic fork 12. The lower end of the telescopic fork 12 is provided with a support spring 13 installed inside the positioning column 3. The upper end of the telescopic fork 12 is equipped with a positioning roller 14. The lower surface of the turntable 8 is provided with a positioning groove 15 with a wave-shaped top on the inner wall corresponding to the position of the positioning roller 14.

[0032] Working principle:

[0033] The positioning post 3 is secured in the center hole of the reel 2 by the spring telescopic rod 4 and the support roller 5. The height can be adjusted in advance by turning the adjusting bolt 16 according to the thickness of the reel 2, so that the limiting sleeve 10 is suspended on the outside of the top edge of the reel 2. The unwound copper wire 1 passes through the limiting sleeve 10 and is then delivered to the production line. The upper and lower ends of the limiting sleeve 10 are smooth rounded corners, thus avoiding scratches and defects caused by the copper wire 1 during unwinding. During unwinding, the copper wire 1 drives the turntable 8 and the support rod 9 to rotate around the fixed rod 6, and the positioning roller 14 rolls along the positioning groove 15. When the copper wire 1 stops being pulled and unwound, the copper wire 1 also stops pulling and drives the turntable 8 to rotate. The telescopic fork 12 elastically supports the positioning roller 14, so that the positioning roller 14 stops at the crest of the wave-shaped positioning groove 15 below the turntable 8, preventing the support rod 9 and the turntable 8 from continuing to rotate due to inertia and causing the copper wire 1 to overwind and become entangled. It is simple and convenient to use and brings convenience to production.
