[0018] Compared with the prior art, the present invention provides a wrapping device for enameled wire processing, which has the following beneficial effects:

[0019] 1. The winding equipment for enameled wire processing drives the winding wheel to unwind the winding tape by rotating the turntable, and winds the unwound winding tape around the wrapped raw material. However, only a part of the winding tape wrapped around the raw material is unwound, and the unwound part will be scattered outside. The cam drives the abutment wheel to rotate, so that the unwound and scattered part of the winding tape can be rewound onto the winding wheel. At the same time, the inertia generated by the rotation of the abutment wheel will straighten the winding tape wrapped around the raw material, so that the winding tape is in a taut state, so that the wound winding tape can be tightly wrapped around the raw material, which is convenient for the subsequent dipping process.

[0020] 2. The winding equipment for enameled wire processing can be equipped with several winding wheels on the arrangement shaft through the arrangement of the arrangement shaft and the winding wheel. The number of winding layers required can be adapted according to the bending stress limit of the arrangement shaft. The upper limit of the number of winding layers is higher. The other winding wheels that are not involved in the operation can be directly replaced after the winding tape on the participating winding wheels is used up, which reduces the time for replacing the winding wheels and greatly reduces the workload of the staff.

[0021] 3. The wrapping equipment for enameled wire processing can connect two adjacent winding wheels in series, that is, the end of the winding tape on the upper winding wheel and the beginning of the winding tape on the lower winding wheel are adhered to each other to achieve series connection. Therefore, when multiple layers of wrapping are not required, the redundant winding wheels can be connected in series, that is, continuous wrapping can be achieved for a long time, effectively reducing the number of times the winding wheels are replaced.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0031] like Figure 1-6 As shown, it includes a device housing 10 and an outer cover 11 movably connected to the device housing 10, so that the entire wrapping process is in a closed environment, preventing external dust and other debris from adhering to the winding tape, thereby affecting the wrapping quality and avoiding bulging and wrinkling of the winding tape. A handle is also provided on the outer cover 11 for opening and closing the outer cover 11. A plurality of switches are provided on the end face of the device housing 10 near the outer cover 11 for controlling the state of the entire wrapping device. The wrapping devices on both sides of the device housing 10 are provided with winding assemblies. Power components are also provided on both sides of the equipment housing 10. The power components transmit power to the turntable 20 through a belt 41. The power component includes a synchronous motor 40. A motor pulley 401 is fixed on the motor shaft of the synchronous motor 40. The motor shaft on the motor pulley 401 extends into the equipment housing 10 and is rotatably connected to it. The equipment housing 10 can be used to fix both sides of the synchronous motor 40, which can effectively avoid shaking of the motor pulley 401 and make its power transmission more stable. The two synchronous motors 40 need to rotate synchronously in the same direction, and the power components can also be transmitted through gears.

[0032] The wrapping device includes a turntable 20 and a protective cover 21. The turntable 20 rotates on the outer peripheral side of the protective cover 21. The protective cover 21 is fixed on the outer surface of the equipment housing 10. The winding assembly is installed in the turntable 20. The turntable 20 is installed on the protective cover 21 through an annular rotating shaft, and the annular rotating shaft extends away from both sides of the arrangement shaft 30 to the outside of the equipment housing 10. A driven pulley 202 is fixed to its outer part, wherein the belt 41 can be sleeved on the driven pulley 202 to provide power for the turntable 20. The annular rotating shaft is fixed to the inner wall of the equipment housing 10 and the protective cover 21 through two inner and outer auxiliary bearings 203 respectively. The two auxiliary bearings 203 can make the turntable 20 rotate easily without contacting the inner wall of the equipment housing 10 and the protective cover 21 to generate friction.

[0033] The outer part of the protective cover 21 is surrounded by the outer peripheral side of the driven pulley 202 and is fixed to the end faces of both sides of the equipment housing 10. A cam 211 is fixed to the side of the protective cover 21 close to the equipment housing 10. The cam 211 is relatively movably connected to the turntable 20. The cam 211 is cam-shaped, wherein the raised part of the cam and the abutment wheel 321 can be frictionally connected or gear-engaged, wherein the cam 211 is in a fixed state, and the abutment wheel 321 rotates around the winding belt 311, and the abutment wheel 321 itself can also rotate. There are through-holes 201 in the middle of the protective cover 21 and the turntable 20, and the raw materials to be wrapped, such as copper wire, glass wire, etc., can be inserted into the threading holes 201.

[0034] The belt winding assembly includes an arrangement shaft 30 and a support rod 32. The support rod 32 slides inside the arrangement shaft 30. The arrangement shafts 30 on both sides are interlocked with each other, and the support rod 32 is rotatably connected to the turntable 20. The support rod 32 is divided into a cylindrical part and a square column part. The square column part slides inside the arrangement shaft 30. The square column part can limit the arrangement shaft 30 from rotating, so that the arrangement shaft 30 can only rotate with the support rod 32, avoiding the winding belt 311 from being completely loosened and causing it to be scattered. The outer peripheral side of the cylindrical part is installed in the turntable 20 through a one-way bearing 322. The one-way bearing 322 can only rotate the support rod 32 in one direction. The end face of the support rod 32 on the side away from the arrangement shaft 30 is fixed with an abutment wheel 321, which abuts against the end face. The wheel 321 rotates in the turntable 20, and the abutting wheel 321 and the raised portion of the cam 211 can come into contact with each other. During the rotation of the turntable 20, after the abutting wheel 321 comes into contact with the raised portion of the cam 211, the abutting wheel 321 can rotate on its own, and it cannot rotate in the opposite direction. Therefore, the rotation of the turntable 20 can drive the winding wheel 31 to unwind the winding belt 311, and the unwound winding belt 311 is wound around the wrapped raw material, but the winding belt 311 wound around the raw material is only partially unwound. The unwound part will be scattered outside, and the cam 211 drives the abutting wheel 321 to rotate, and the unwound and scattered part of the winding belt 311 can be rewound onto the winding wheel 31, and at the same time, the inertia generated by the rotation of the abutting wheel 321 straightens the winding belt 311 wrapped around the raw material, so that the winding belt 311 is in a tensioned state, so that the wound winding belt 311 can be tightly wrapped around the raw material, which is convenient for the subsequent coating process.

[0035] Working principle: When in use, push the arrangement shaft 30 to both sides so that the limit block 301 and the limit groove 303 are disengaged from each other, and the winding wheel 31 can be put on the arrangement shaft 30, and then the starting end of the winding belt 311 is adhered to the winding material, and then the equipment can be started, and the synchronous motors 40 on both sides can be started, so that the motor pulley 401 drives the driven pulley 202 to rotate through the belt 41, thereby driving the turntable 20 to rotate. Since the protective cover 21 is fixed to the equipment housing 10, the cam 211 is in a stationary state, and the rotation of the turntable 20 can drive the winding assembly to rotate, so that the winding belt 311 on the winding wheel 31 is gradually untied, and the untied winding belt 311 will be wound around the winding material.

[0036] When the turntable 20 drives the winding assembly to rotate one circle, the winding wheel 31 will unwind one circle of the winding belt 311 thereon, and at the same time, the unwound winding belt 311 is wound around the wrapped material one circle. At this time, the unwound part of the unwound winding belt 311 is in a loose state, and the turntable 20 rotates one circle, driving the abutment wheel 321 to rotate one circle. When the abutment wheel 321 abuts against the raised part of the cam 211, it can drive the abutment wheel 321 to rotate on its own, and its rotation direction is consistent with the rotation direction of the turntable 20. The abutment wheel 321 rotates on its own and can pass through the support rod The cam 211 of the belt drive mechanism 320 is connected to the belt drive mechanism 321 through the cam 211, and the cam 211 of the belt drive mechanism 321 is connected to the cam 211 through the cam 211. The cam 211 of the belt drive mechanism 321 is connected to the cam 211 through the cam 211, and the cam 211 of the belt drive mechanism 321 is connected to the cam 211 through the cam 211. Example 2

[0037] On the basis of implementation one, a slide rail 302 is further fixed to the outer peripheral side of the arrangement shaft 30, and a number of symmetrical convex points are provided on both side end faces of the slide rail 302. A number of winding pulleys 31 are also set on the arrangement shaft 30, and a winding belt 311 is wound around the winding pulley 31. The material of the winding belt 311 can be a wrapping material such as mica tape, cotton paper tape, aluminum foil, polyester film, etc. A sliding slot 312 and a pulley hole 313 are provided in the middle of the winding pulley 31, wherein the pulley hole 313 cooperates with the arrangement shaft 30, and the sliding slot 312 cooperates with the slide rail 302. The slide rail 302 and the convex points thereon can be used to limit the position of the winding pulley 31 on the arrangement shaft 30, so as to avoid the self-rotation of the winding pulley 31 during operation. The winding belt 311 is caused to be disorderly, and the axial position of the winding wheel 31 can be limited by the convex point, which facilitates the multi-layer winding process and avoids the two adjacent winding wheels 31 from being too close to each other and causing interference. In addition, the setting of the slide rail 302 can also strengthen the strength of the arrangement shaft 30, increase the bending stress of the arrangement shaft 30, and enable more winding wheels 31 to be placed on the arrangement shaft 30. A limiting block 301 is provided on the end face of the arrangement shaft 30 on one side, and a limiting groove 303 is provided on the end face of the arrangement shaft 30 on the other side. The limiting block 301 and the limiting groove 303 cooperate with each other, and the cooperation method of the two can be a snap connection or a magnetic connection. The limiting block 301 can avoid the bending of the two arrangement shafts 30 after cooperation.

[0038] By setting the arrangement shaft 30 and the winding wheel 31, a plurality of winding wheels 31 can be set on the arrangement shaft 30 until the ultimate bending stress of the arrangement shaft 30 is reached. Multi-layer wrapping can be performed according to product requirements. When two-layer wrapping is required, the winding belts 311 of two of the winding wheels 31 can be wound on the raw material, and then two-layer wrapping can be performed. The same applies to three-layer wrapping. Therefore, the number of required wrapping layers can be adapted to the bending stress limit of the arrangement shaft 30. The upper limit of the number of wrapping layers is higher, and the other winding wheels 31 that are not involved in the operation can be wound on the raw material. The winding belt 311 on the used winding wheel 31 can be directly replaced after use, which reduces the time for replacing the winding wheel 31. In addition, two adjacent winding wheels 31 can be connected in series with each other, that is, the end of the winding belt 311 on the previous winding wheel 31 and the beginning of the winding belt 311 on the next winding wheel 31 are adhered to each other to achieve series connection. Therefore, when multi-layer wrapping is not required, the redundant winding wheels 31 can be connected in series, that is, wrapping can be carried out continuously for a long time, effectively reducing the number of times the winding wheels 31 are replaced.

[0039] There are at least two groups of symmetrical limiting grooves 3121 on the inner walls on both sides of the sliding slot 312. The limiting grooves 3121 cooperate with the protrusions on the slide rail 302. Through the cooperation of the two, the winding wheel 31 can be limited to prevent the winding wheel 31 from sliding freely on the arrangement shaft 30, causing a large number of wrinkles when the winding belt 311 is wound, thereby affecting the subsequent process.

[0040] After the belt winding wheel 31 is installed, the arrangement shafts 30 on both sides can be pulled to make the limit blocks 301 and the limit grooves 303 engage with each other, and the installation of the belt winding wheel 31 can be completed at this time. Example 3

[0041] like Figure 6 and Figure 7As shown, a leveling component is also provided in the threading hole 201 in the wrapping device at the outlet of the wrapped raw material, and the leveling component includes a ring 50 fixed in the threading hole 201, and at least two pressure strips 501 are fixed in the ring 50 through a connecting rod 502. The pressure strips 501 are spirally arranged, and the end faces on both sides are chamfered, and the rounded corners are pressing surfaces 5011. The diameter of the cylindrical cavity formed by the pressure strips 501 is consistent with the diameter of the wrapped raw material after winding, that is, when the turntable 20 rotates, the pressure strips 501 are also driven to rotate by the ring 50, and the reverse direction of rotation of the pressure strips 501 is consistent with the winding direction of the raw material, so that when the turntable 20 rotates, the surface of the wrapped raw material can be spirally leveled. If dust occurs or wrinkles and looseness are generated after the winding belt 311 is superimposed, it can be leveled by the pressure strips 501, which can further ensure that the wrapped raw material and the winding belt 311 are in a tight fit, avoiding problems such as paint accumulation in the next painting process.

[0042] The cam 211 drives the contact wheel 321 to rotate, and the unwound part of the winding belt 311 can be rewound onto the winding wheel 311. At the same time, the inertia generated by the rotation of the contact wheel 321 can straighten the winding belt 311 wound on the raw material, so that the winding belt 311 is in a tensioned state, so that the wound winding belt 311 can be tightly wrapped on the raw material, which is convenient for the subsequent varnishing process. Several tape winding wheels 31 are set, can adapt to the number of plies of required wrapping according to the bending stress limit of arrangement shaft 30, the upper limit of its wrapping number of plies is higher, and other tape winding wheels 31 that do not participate in operation, can directly replace after the winding band 311 on the tape winding wheel 31 that has participated in uses finishes, reduce the time that changes tape winding wheel 31, greatly reduced staff's work intensity; And two adjacent tape winding wheels 31 can be connected in series together mutually, promptly the end of the winding band 311 on a last tape winding wheel 31 and the beginning of the winding band 311 on the next tape winding wheel 31 are adhered together mutually, reach series connection, so when needing not to multilayer wrapping, can unnecessary tape winding wheel 31 all be connected in series together, promptly can wrap continuously for a long time, effectively reduce the number of times that change tape winding wheel 31.
