[0002] The wire pay-off machine is one of the indispensable equipment in the production process of wire materials such as copper wires. Its main function is to unwind the copper wire from the reel or wire spool and perform precise wire pay-off operations according to production requirements. The wire pay-off machine usually consists of parts such as a wire spool and a motor. The wire spool is used to store and fix the copper wire, and the motor provides power for the wire pay-off operation of the wire spool, so that the copper wire can be paid off at a set speed and direction.

[0003] At present, after the existing wire pay-off machine processes a batch of wire materials for wire pay-off, it is necessary to cut the wire materials and then perform the wire pay-off processing for the next batch. After cutting the wire materials, the wire materials on the wire spool of the wire pay-off machine will have a certain degree of springback and loosening. Each time, it is necessary for workers to sort out, wind and tighten the wire materials on the wire spool. This process will bring certain operation difficulties and waste working hours to the operators, and it is also easy to cause the wire materials to be disordered during the sorting process.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as a limitation to the present invention.

[0021] As Figure 1 and Figure 2 shown, the wire unwinding machine with an anti-loosening structure according to the present invention includes a tabletop 1. A wire unwinding mechanism 2 is provided at the top end of the tabletop 1. The wire unwinding mechanism 2 includes a placing rack 203 and a wire reel 204. A rotating shaft 202 extending to the outside is rotatably connected to the inside of the tabletop 1 through a bearing. One end of the rotating shaft 202 is provided with a placing rack 203. A wire reel 204 is clamped on the outside of the placing rack 203. A motor 201 connected to the rotating shaft 202 through a coupling is installed in the installation frame at the bottom end of the tabletop 1.

[0022] Referring to Figure 1 and Figure 2 it can be known that the wire reel 204 is clamped on the placing rack 203. Then, one end of the wire is passed through the guiding sleeve 403 and the anti-loosening plate 301. Then, the motor 201 is started, so that the output end of the motor 201 drives the rotating shaft 202 to rotate, and the placing rack 203 and the wire reel 204 rotate together with the rotating shaft 202, thereby realizing the wire unwinding operation.

[0023] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 it can be known that a guiding mechanism 4 is provided on the top end of the tabletop 1 on one side of the rotating shaft 202. The guiding mechanism 4 includes a sliding plate 402 and a guiding sleeve 403. A reciprocating lead screw 401 extending to the outside is rotatably connected to the inside of the tabletop 1 on one side of the rotating shaft 202 through a bearing. A sliding plate 402 is engaged with the outside of the reciprocating lead screw 401. A pulley set 404 is sleeved on the outer surfaces of the rotating shaft 202 and the reciprocating lead screw 401. A guiding sleeve 403 is provided at the front end of the sliding plate 402.

[0024] Referring to Figure 1 , Figure 2 ,Figure 3 and Figure 4 It can be seen that since the reciprocating lead screw 401 and the rotating shaft 202 are linked by a pulley set 404, and the sliding plate 402 is slidably connected to the table top 1 through the limiting rod 5, during the rotation of the rotating shaft 202, the reciprocating lead screw 401 rotates together, and at the same time, the sliding plate 402 makes a reciprocating movement in the vertical direction. Thus, the wire can be guided through the guide sleeve 403, and further, the operation of wire winding and unwinding can be facilitated, providing convenience.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It can be seen that a wire loosening prevention mechanism 3 is provided at the front end of the sliding plate 402. The wire loosening prevention mechanism 3 includes an electric push rod 304 and a linkage rope 307. An installation frame 305 is provided on one side of the sliding plate 402. A movable plate 302 is slidably connected to the inner side of the installation frame 305. A wire loosening prevention plate 301 is provided at one end of the movable plate 302. Guide plates 303 are provided at the ends of the two movable plates 302 that are close to each other. An electric push rod 304 is installed between the installation frame 305 and one of the guide plates 303. Two wire loosening prevention plates 301 are symmetrically arranged about the central axis of the installation frame 305. A limiting wheel 306 is provided between the two guide plates 303 on the inner side of the installation frame 305. A linkage rope 307 sleeved on the outer surface of the limiting wheel 306 is connected between the two guide plates 303. The wire loosening prevention plate 301 is arranged in an arc structure, and an elastic pad is provided on the inner side of the wire loosening prevention plate 301.

[0026] Refer to Figure 1 、 Figure 3 and Figure 4 It can be seen that since the two guide plates 303 are linked by the linkage rope 307, and the guide plates 303 are slidably connected to the installation frame 305, during the working and extending process of the electric push rod 304, one guide plate 303 moves vertically downward, and the other guide plate 303 moves vertically upward, and at the same time, the two wire loosening prevention plates 301 move closer to each other. Thus, the wire can be locked by the wire loosening prevention plates 301, so that the wire can be effectively prevented from loosening and getting disordered when being cut, improving the efficiency and reducing the difficulty.

[0027] Refer to Figure 2 It can be seen that a limiting hole is opened at one end of the sliding plate 402 away from the guide sleeve 403. A limiting rod 5 passing through the limiting hole is provided on the top end of the table top 1 on one side of the reciprocating lead screw 401. The sliding plate 402 and the table top 1 form a sliding structure through the limiting hole and the limiting rod 5, which can play a role in supporting and limiting, so that the stability of the sliding plate 402 during the sliding process can be increased.

[0028] Working principle of the wire pay-off machine with a loosening prevention structure according to the present utility model: During use, the wire reel 204 is clamped on the placement rack 203. Then, one end of the wire is passed through the guiding sleeve 403 and the anti-loosening plate 301. After that, the motor 201 is started, so that the output end of the motor 201 drives the rotating shaft 202 and the reciprocating lead screw 401 to rotate under the action of the pulley group 404, causing the placement rack 203 and the wire reel 204 to rotate together with the rotating shaft 202, thereby realizing the wire pay-off operation. During this process, the sliding plate 402 makes a reciprocating movement in the vertical direction, so that the wire can be guided through the guiding sleeve 403 to improve convenience.
