Technical Field
[0001] This utility model relates to the field of enameled wire processing technology, specifically an automatic enameled wire cutting machine. Background Technology
[0002] During the processing and production of enameled wire, it needs to be wound onto the surface of a spool. After a certain amount of enameled wire is wound onto the spool, it needs to be cut, and a new spool needs to be replaced for winding. Common wire-cutting devices use a lever to pull the enameled wire to one side, causing the wire to get caught between a wall panel and a blade, which then cuts it. However, after cutting, the end of the wire often gets stuck on the blade, requiring manual removal. This manual removal, where the hand is close to the blade, can easily result in finger cuts. Therefore, those skilled in the art have provided an automatic enameled wire cutting machine to solve the problems mentioned in the background section. Utility Model Content
[0003] The purpose of this invention is to provide an automatic wire breaking machine for enameled wires to solve the problems mentioned in the background art.

[0017] Please see Figures 1-2 In this embodiment of the utility model, an automatic wire cutting machine for enameled wire includes a wire cutting box 1.

[0018] The wire breaking mechanism includes a mounting bracket 26, which is fixed to the top of the wire breaking box 1. A second cylinder 27 is installed inside the mounting bracket 26. The driving end of the second cylinder 27 faces downward and extends into the wire breaking box 1. An upper wire breaking component 28 is installed at the driving end of the second cylinder 27. A lower wire breaking component 25 is fixed inside the wire breaking box 1 and is located directly below the upper wire breaking component 28.
[0019] Preferably, the upper surface of the lower wire breaker 25 has a groove that allows the lower end of the upper wire breaker 28 to extend into it. A cutting blade 29 is installed on the surface of the groove. The lower surface of the upper wire breaker 28 has a blade groove 30 into which the cutting blade 29 can be inserted. When the upper wire breaker 28 is pressed down and the enameled wire is cut by the cutting blade 29 and the upper wire breaker 28, the cut end of the enameled wire is inserted between the upper wire breaker 28 and the lower wire breaker 25. After the upper wire breaker 28 is reset, the end of the enameled wire is in a relaxed state and can be pulled and fixed to the surface of the new wire spool 10. Since the cutting blade 29 is located inside the lower wire breaker 25, it can prevent people from accidentally cutting themselves by getting their fingers too close to the cutting blade 29 when pulling the end of the enameled wire.
[0020] Preferably, the top of the spool frame 8 is provided with a lower arc plate 11, the inner arc surface of the lower arc plate 11 faces upward, one end of the lower arc plate 11 is hinged to an upper arc plate 12, and the other ends of the lower arc plate 11 and the upper arc plate 12 are fixed by bolts or clips. The inner arc surface of the upper arc plate 12 faces downward, and the inner arc surfaces of the lower arc plate 11 and the upper arc plate 12 together form a circle. The end shaft of the spool 10 is rotatably disposed between the lower arc plate 11 and the upper arc plate 12.
[0021] Preferably, a horizontal plate 14 is fixedly connected to the surface of the spool frame 8 on the side away from the spool 10. A sliding plate 18 is slidably disposed on the upper surface of the horizontal plate 14. A first cylinder 15 is fixedly connected to the lower surface of the horizontal plate 14. A push rod 16 is fixedly connected to the driving end of the first cylinder 15. The push rod 16 is L-shaped, and the other end of the push rod 16 is fixedly connected to the surface of the sliding plate 18. A motor 17 is fixedly connected to the upper surface of the sliding plate 18. A docking shaft 19 is fixedly connected to the driving end of the motor 17. A docking groove 20 is opened on the shaft of the spool 10. The docking shaft 19 and the docking groove 20 are adapted to each other, and the docking shaft 19 is snapped into the inside of the docking groove 20.
[0022] Preferably, a top rod 9 is fixedly connected to the upper surface of the upper arc plate 12, a spring telescopic rod 13 is fixedly connected to the lower surface of the top rod 9, a roller frame 21 is fixedly connected to the movable end of the spring telescopic rod 13, and a roller 22 is rotatably mounted at the lower end of the roller frame 21.
[0023] Preferably, a second electrode 24 is fixedly connected to the upper surface of the roller 22, and a first electrode 23 is installed on the surface of the spring telescopic rod 13. The first electrode 23 is located directly above the second electrode 24, and the first electrode 23, the second electrode 24, and the second cylinder 27 are electrically connected.
[0024] The working principle of this utility model is as follows: During the winding of enameled wire, after a certain amount of wire is wound around the surface of the spool 10, the roller 22 is pushed upward, causing the second electrode 24 to contact the first electrode 23. At this time, the second cylinder 27 is energized, controlling the upper wire-cutting component 28 to move down into the interior of the first cylinder 15. The blade groove 30 and the cutting blade 29 squeeze each other to perform the wire-cutting operation. Then, the spool 10 is removed and replaced. First, the motor 17 is turned off, and the push rod 16 is controlled by the first cylinder 15 to move the docking shaft 19 out of the docking groove 20. Then, the upper arc is opened. During the process of fixing the upper arc plate 12 and the lower arc plate 11, the first electrode 23 and the second electrode 24 will be separated by the elastic force inside the spring telescopic rod 13. The second cylinder 27 pulls the upper wire break 28 to reset, removes the wire spool 10, and replaces the new wire spool 10 between the upper arc plate 12 and the lower arc plate 11. The push rod 16 is controlled by the first cylinder 15 again, so that the docking shaft 19 extends into the docking groove 20. Then the end of the wire is pulled. Since the cutting blade 29 is located inside the lower wire break 25, when pulling the wire, it can prevent the fingers from getting too close to the cutting blade 29 and accidentally cutting themselves.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
