Description

Technical Field

[0001] The present invention relates to the technical field of wire mylar, and in particular to a mylar machine for producing composite enameled round copper wire. Background Art

[0002] Mylar film, a kind of polyester film, also known as mylar paper and insulating tape, is often used in the production of wires and cables.

[0003] In the wire and cable production industry, it often involves the process of winding mylar film around the surface of copper wire to play a role in shielding, insulation or flame retardance. The mylar machine is a device for wrapping mylar film on the surface of copper wire. However, the existing mylar machines have the problem of uneven wrapping of mylar film.

[0007] In the above-mentioned mylar machine for producing composite enameled copper round wire, the auxiliary wrapping structure includes a positioning table fixedly arranged on the side wall of the fixed plate. The positioning table is arranged in an inverted L-shaped structure. The bottom of the positioning table is fixedly connected to the top of the processing table. A first gear coaxially arranged with the copper round wire is provided in the positioning table. A through hole that is in clearance fit with the copper round wire is penetrated and opened at the rotation center of the first gear.

A machine cavity is opened in the inner wall of the positioning table, and the second motor is fixedly arranged in the machine cavity.

[0008] In the above-mentioned mylar machine for producing composite enameled copper round wire, the rotation center of the second gear is connected with a threaded rod.

The advantage of this is that the first blade is directly above the copper round wire, and the second blade is directly above the mylar film. When performing the wrapping work, air flow treatment is carried out on the copper round wire and the mylar film, which can effectively reduce the problem of floating dust adhesion during wrapping and improve the service performance of the cable and wire.

[0014] 2. When performing the wrapping work, the moving block realizes reciprocating movement under the screw drive with the threaded rod and the forward and reverse rotation of the second motor, and adjusts the position of the pressing block through the contraction of the conductive spring.

[0015] 3. The rotating shaft connected to the rotating cylinder is frictionally driven and connected to the second friction wheel on the first transmission shaft through the first friction wheel. The advantage of this is that due to the transmission resistance of the friction drive, the rotating cylinder always has a tendency to rotate in one direction, which makes the mylar film always in an open state, effectively maintaining the tension during wrapping and improving the wrapping effect.

Detailed implementation manner

[0021] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Embodiment

[0023] Refer to Figures 1-4 , a mylar machine for producing composite enameled copper round wire, comprising a processing table 1, a fixed plate 2 is fixedly arranged on the top of the processing table 1, a cross plate 3 is vertically arranged on the top of the fixed plate 2, a rotating shaft 4 is rotatably arranged in the fixed plate 2, a rotating cylinder 5 is fixedly arranged at one end of the rotating shaft 4 outside the fixed plate 2, a mylar film 6 is wound in the rotating cylinder 5, a copper round wire 7 is arranged below the mylar film 6, the copper round wire 7 is connected with an auxiliary wrapping structure, and the cross plate 3 is connected with a flow driving structure.

[0024] The flow driving structure includes a first motor 8 fixedly arranged on the top of the cross plate 3. The output shaft of the first motor 8 penetrates through the inner wall of the cross plate 3, and a part below the cross plate 3 is fixedly connected with a first transmission shaft 9. The bottom of the first transmission shaft 9 is fixedly connected with a first blade 10. A second transmission shaft 11 is arranged on one side of the first transmission shaft 9 close to the rotating cylinder 5. A synchronous pulley 12 is fixedly connected to the parts of the first transmission shaft 9 and the second transmission shaft 11 at the same height. The two synchronous pulleys 12 are jointly connected with a synchronous belt 13. In this way, the first motor 8 can drive the first transmission shaft 9 and the second transmission shaft 11 to rotate simultaneously, achieving the effect of driving multiple rotating shafts with a single motor. A second blade 14 is fixedly arranged on the part of the second transmission shaft 11 below the synchronous pulley 12. The auxiliary wrapping structure includes a positioning table 15 fixedly arranged on the side wall of the fixing plate 2. The positioning table 15 is arranged in an inverted L-shaped structure. The horizontal end part of the top of the positioning table 15 is fixed to the fixing plate 2, and the bottom of the positioning table 15 is fixed to the top of the processing table 1. The bottom of the positioning table 15 is fixedly connected to the top of the processing table 1. A first gear 16 coaxially arranged with the copper round wire 7 is provided in the positioning table 15. A through hole for clearance fit with the copper round wire 7 is formed through the center of rotation of the first gear 16, facilitating the passing of the copper round wire 7. A second gear 17 is meshed above the first gear 16, and a third gear 18 is meshed above the second gear 17. A second motor 19 is fixedly arranged at the center of rotation of the third gear 18. A machine cavity is formed in the inner wall of the positioning table 15, and the second motor 19 is fixedly arranged in the machine cavity. The first gear 16, the second gear 17, and the third gear 18 are driven to rotate simultaneously by the second motor 19.

[0025] The rotation center of the second gear 17 is connected with a threaded rod 20. The smooth shaft part of the threaded rod 20 penetrates through the side wall of the positioning table 15 and is fixedly connected with the second gear 17. The threaded part of the threaded rod 20 is in screw transmission connection with a moving block 21. Thus, when the threaded rod 20 rotates, it will drive the moving block 21 to move. A moving groove 22 with a size matching that of the moving block 21 is formed in the fixed plate 2. The moving block 21 is slidably connected in the moving groove 22 and its bottom abuts against the top of the processing table 1. The threaded length of the threaded rod 20 is greater than the length of the moving groove 22. Thus, when the moving block 21 moves, it will move out of the moving groove 22. A wire inlet groove 23 is horizontally formed through the moving block 21. The wire inlet groove 23 is in clearance fit with the copper round wire 7, which facilitates the wrapping and passing of the copper round wire 7. A sleeve 24 is coaxially rotatably connected to the inner wall of the moving block 21. A ring block 25 is fixedly arranged on the side of the sleeve 24 close to the positioning table 15. An annular sleeve 26 is sleeved on and slidably connected to the outside of the ring block 25. One end of the annular sleeve 26 away from the ring block 25 is coaxially fixedly connected with the first gear 16. A plurality of pressing blocks 27 are arranged inside the sleeve 24. The plurality of pressing blocks 27 are annularly arranged with the central axis of the sleeve 24 as the polar axis and are slidably connected. One end of each pressing block 27 away from the central axis of the sleeve 24 is fixedly connected with a conductive spring 28. The other end of each conductive spring 28 is fixedly arranged on the inner side wall of the sleeve 24. The plurality of conductive springs 28 are commonly electrically connected to an external power supply circuit. Thus, when the plurality of conductive springs 28 are simultaneously energized, the plurality of pressing blocks 27 will contract simultaneously, and when the conductive springs 28 are de-energized, the plurality of pressing blocks 27 can be released to jointly fix the part of the copper round wire 7 located in the wire inlet groove 23.

[0026] The second motor 19 is a forward and reverse motor and is set to alternate between forward rotation and reverse rotation with the same time. Thus, the moving block 21 will move reciprocally in a periodic manner for wire inlet. A first friction wheel 29 is fixedly arranged on the part of the rotating shaft 4 outside the rotating cylinder 5. The first friction wheel 29 is in friction transmission connection with a second friction wheel 30. The second friction wheel 30 is coaxially fixedly connected with the first transmission shaft 9. The transmission ratio between the first friction wheel 29 and the second friction wheel 30 is 0.1, and the transmission ratio is small. Therefore, the first friction wheel 29 will rotate slightly, and the first friction wheel 29 can slip by reducing the extrusion force between the first friction wheel 29 and the second friction wheel 30. Thus, when the first motor 8 drives the first transmission shaft 9 to rotate, a rotational force can always be provided to the rotating shaft 4. The rotating shaft 4 is rotatably connected with the fixed plate 2 through a bearing. The bottom of the moving block 21 and the part of the processing table 1 in contact with the moving block 21 are polished. The first blade 10 is disposed directly opposite the copper round wire, and the second blade 14 is disposed directly opposite the rotating cylinder 5.

[0027] When the present invention is in use, first, the copper round wire 7 is passed through the wire inlet groove 23 and the through hole in the first gear 16 at the same time, and the Mylar film 6 is pre-wrapped around the incoming copper round wire. Then, the first motor 8 and the second motor 19 are started simultaneously. In this way, the first motor 8 drives the first blade 10 and the second blade 14 to rotate at the same time, and the air flow treatment is carried out on the copper round wire 7 and the Mylar film 6 respectively, which can effectively reduce the problem of floating dust adhesion during wrapping and improve the service performance of the cable and wire.

[0028] When the second motor 19 is working, it will drive the first gear 16, the second gear 17 and the third gear 18 to rotate at the same time, and cut off the power supply of a plurality of conductive springs 28 located in the sleeve 24. In this way, a plurality of pressing blocks 27 will fix the copper round wire 7, and through the screw drive connection between the threaded rod 20 and the moving block 21, the copper round wire 7 realizes the feeding movement. At this time, the first gear 16 drives the sleeve 24 to rotate, and pulls the annular block 25 out of the annular sleeve 26, so as to meet the requirement of the movement of the moving block 21, and makes the sleeve 24 realize the rotational feeding movement while fixing the copper round wire 7. In this way, the copper round wire 7 will automatically wind the Mylar film 6 and wrap it. The second motor 19 is a forward and reverse motor. When the second motor 19 rotates in reverse, it controls the power supply of a plurality of conductive springs 28 to be cut off, which will loosen the fixation of the copper round wire 7 and make the moving block 21 move in the reverse direction, so as to prepare for the next rotational feeding movement, realizing the effect of automatically packaging the longer copper round wire 7 and facilitating use.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
