Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to an automatic winding machine wire cutting device. Background Technology

[0002] A winding machine is a device that winds a thread-like object onto a specific workpiece, typically used for winding copper wire. Commonly used winding machines wind enameled copper wire (for inductors in electronic and electrical products), enameled aluminum wire, textile wire (for yarn spools and coils used in textile machines), as well as heating wire for electric heating appliances, solder wire, electrical wires, and cables. Most electrical products require inductors wound from enameled copper wire (or simply enameled wire), and winding machines can complete this one or more processing steps. The textile industry often uses cotton yarn and synthetic fiber threads to wind various yarn spools and coils suitable for textile machines; these can also be processed using winding machines.

[0003] Existing winding machine cutting devices can only perform simple cutting of the wire, resulting in tangled wire ends after cutting, which is not convenient for the next winding and is also not conducive to the automation of the winding machine, thus failing to meet the usage requirements of automatic winding machines.

[0004] Therefore, we propose an automatic winding machine wire cutting device. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide an automatic winding machine cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic winding machine wire cutting device, comprising a mounting frame, wherein an automatic wire cutting mechanism is provided on the inner wall of the mounting frame, the automatic wire cutting mechanism includes a servo motor, and the bottom of the servo motor is fixedly connected to the top of the mounting frame, the output end of the servo motor movably passes through the top of the inner wall of the mounting frame, a positive lead screw is fixedly installed on the output end of the servo motor, a negative lead screw is fixedly installed on the bottom of the positive lead screw, and the bottom of the negative lead screw is movably connected to the bottom of the inner wall of the mounting frame, and a first lifting mounting plate is threadedly connected to the outer wall of the positive lead screw.

[0007] Preferably, a limiting guide rod is movably installed on the left side of the inner wall of the first lifting mounting plate, and the top of the limiting guide rod is fixedly connected to the top left side of the inner wall of the mounting frame, and the bottom of the limiting guide rod is fixedly connected to the bottom left side of the inner wall of the mounting frame.

[0013] This utility model provides an automatic winding machine wire cutting device. It has the following beneficial effects:

[0014] 1. This automatic winding machine wire cutting device, by setting an automatic wire cutting mechanism, allows for the activation of a servo motor during operation. The output of the servo motor drives the positive and negative lead screws to rotate simultaneously. Since the outer walls of the positive and negative lead screws are respectively threaded with a first lifting mounting plate and a second lifting mounting plate, the first and second lifting mounting plates move towards the center simultaneously. The first and second lifting mounting plates respectively drive the first clamping plate and the second clamping plate to move towards the center simultaneously, clamping and fixing the wire. Simultaneously, the first and second lifting mounting plates respectively drive the first and second wire cutting blades to move towards the center, cutting the wire. Due to the clamping of the wire by the first and second clamping plates, the cut wire ends are neat, facilitating the next winding process. This facilitates the automation of the winding machine and meets the usage requirements of an automatic winding machine.

[0015] 2. The automatic winding machine wire cutting device is equipped with a positive wire screw and a negative wire screw. The positive wire screw and the negative wire screw have self-locking characteristics, which makes the first clamping plate and the second clamping plate more stable when clamping the wire, and prevents shaking or displacement, thereby further ensuring the cutting effect and accuracy.

[0026] Example 1: An automatic winding machine wire cutting device, such as Figures 1-2 As shown, the device includes a mounting frame 10, and an automatic wire cutting mechanism 11 is provided on the inner wall of the mounting frame 10. The automatic wire cutting mechanism 11 includes a servo motor 12, and the bottom of the servo motor 12 is fixedly connected to the top of the mounting frame 10. The output end of the servo motor 12 movably passes through the top of the inner wall of the mounting frame 10. A positive lead screw 13 is fixedly installed on the output end of the servo motor 12. By setting up the automatic wire cutting mechanism 11, the servo motor 12 can be started during use, and the output end of the servo motor 12 drives the positive lead screw 13 and the negative lead screw 14 to rotate simultaneously. Since the outer walls of the positive lead screw 13 and the negative lead screw 14 are respectively threadedly connected to a first lifting mounting plate 15 and a second lifting mounting plate 19, the first lifting mounting plate... The first lifting mounting plate 15 and the second lifting mounting plate 19 move towards the center simultaneously. The first lifting mounting plate 15 and the second lifting mounting plate 19 respectively drive the first clamping plate 17 and the second clamping plate 20 to move towards the center simultaneously. The first clamping plate 17 and the second clamping plate 20 can clamp and fix the wire. At the same time, the first lifting mounting plate 15 and the second lifting mounting plate 19 respectively drive the first wire cutting blade 18 and the second wire cutting blade 21 to move towards the center simultaneously. The first wire cutting blade 18 and the second wire cutting blade 21 can cut the wire. Due to the clamping of the wire by the first clamping plate 17 and the second clamping plate 20, the cut wire ends are neat, which is convenient for the next wire threading and winding. This is conducive to the automation of the winding machine and meets the usage requirements of the automatic winding machine.

[0027] Example 2: Based on Example 1, as follows Figure 2As shown, a reverse threaded rod 14 is fixedly installed at the bottom of the positive threaded rod 13, and the bottom of the reverse threaded rod 14 is movably connected to the bottom of the inner wall of the mounting frame 10. A first lifting mounting plate 15 is threadedly connected to the outer wall of the positive threaded rod 13. A limit guide rod 16 is movably installed on the left side of the inner wall of the first lifting mounting plate 15, and the top of the limit guide rod 16 is fixedly connected to the top left side of the inner wall of the mounting frame 10. The bottom of the limit guide rod 16 is fixedly connected to the bottom left side of the inner wall of the mounting frame 10. By setting the positive threaded rod 13 and the reverse threaded rod 14, which have self-locking characteristics, the first clamping plate 17 and the second clamping plate 20 are more stable when clamping the wire, and there will be no shaking or displacement, further ensuring the cutting effect and accuracy.

[0028] Example 3: Based on Examples 1 and 2, as follows... Figure 3 As shown, a first clamping plate 17 is fixedly installed at the bottom middle of the first lifting mounting plate 15, a first cutting blade 18 is fixedly installed at the bottom rear end of the first lifting mounting plate 15, a second lifting mounting plate 19 is threadedly connected to the outer wall of the reverse threading rod 14, and the left side of the inner wall of the second lifting mounting plate 19 is movably connected to the outer wall of the limiting guide rod 16. A second clamping plate 20 is fixedly installed at the top middle of the second lifting mounting plate 19, and the top of the second clamping plate 20 is in movable contact with the bottom of the first clamping plate 17. A second cutting blade 21 is fixedly installed at the top rear end of the second lifting mounting plate 19, and the top of the second cutting blade 21 is in movable contact with the bottom of the first cutting blade 18.

[0029] The working principle of this utility model:

[0030] In use, the wire of the winding machine is first placed between the first clamping plate 17 and the second clamping plate 20. Then, the servo motor 12 is started. The output end of the servo motor 12 drives the positive lead screw 13 and the negative lead screw 14 to rotate simultaneously. Since the outer walls of the positive lead screw 13 and the negative lead screw 14 are respectively threaded with the first lifting mounting plate 15 and the second lifting mounting plate 19, and the left side of the inner wall of the first lifting mounting plate 15 and the second lifting mounting plate 19 are movably connected to the limiting guide rod 16, when the positive lead screw 13 and the negative lead screw 14 rotate, the first lifting mounting plate 15 and the second lifting mounting plate 19 will move in relative or opposite directions along the limiting guide rod 16, thereby driving the first clamping plate 17 and the second clamping plate 20 to clamp or release the wire. Simultaneously, as the first lifting mounting plate 15 and the second lifting mounting plate 19 move, the first cutting blade 18 and the second cutting blade 21 also move accordingly. When the blades of the first cutting blade 18 and the second cutting blade 21 come into contact with each other, the wire can be cut. Furthermore, since the tops of the first clamping plate 17 and the second clamping plate 20 are in contact, the first clamping plate 17 and the second clamping plate 20 can automatically release after the wire is cut, facilitating the removal of the processed wire.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
