Description

Technical Field

[0001] This application relates to the technical field of enameled wire production, and particularly to an enameled wire oven with an independent drying channel. Background Art

[0002] Existing enameled wire ovens generally have painting equipment installed at the inlet end of the drying channel. The wire stock to be processed into enameled wire first passes through the painting equipment, and the painting equipment applies paint to the surface of the wire stock. Then, it passes through the drying channel and is dried by the drying equipment for the just-applied paint. After that, it returns to the painting equipment to be painted again. Finally, the finished enameled wire is obtained after multiple painting and drying processes.

[0003] However, since the drying channel in the current enameled wire oven is an integral drying channel that can dry multiple enameled wires simultaneously, the heat source of the enameled wire oven dries the enameled wires in the integral drying channel by blowing hot air into it. When the number of enameled wires to be dried at the same time is large, two adjacent enameled wires are likely to affect each other, reducing the drying efficiency of both, and consequently resulting in a low drying efficiency of the enameled wire oven.

[0004] In view of this, there is a need to provide an enameled wire oven with an independent drying channel. Summary of the Invention

[0005] To solve the problem that the drying channel in the existing enameled wire oven is an integral drying channel and the drying efficiency is low when drying multiple enameled wires simultaneously, this application provides an enameled wire oven with an independent drying channel.

[0006] An enameled wire oven with an independent drying channel provided by this application adopts the following technical solution: It includes a box body, a painting assembly, and a heat source. A receiving through groove is formed on the box body. A plurality of partition plates are arranged in parallel at intervals on the groove wall of the receiving through groove, and the receiving through groove is divided into a plurality of drying channels by the plurality of partition plates;

[0007] The painting assembly includes a plurality of painting units, and the drying channels correspond to the painting units one by one. Each painting unit can paint a single wire passing through it;

[0008] Each drying channel is communicated with the air outlet of the heat source, so that each drying channel can dry the wire painted by the corresponding painting unit.

[0009] By adopting the above technical solution, the arrangement of multiple drying tunnels for multiple wire rods enables the enamelled wire oven with independent drying tunnels to independently dry a single wire rod in each drying tunnel, rather than drying multiple strands of enamelled wire simultaneously in an entire drying tunnel. Thus, the situation where the drying efficiency of the enamelled wire oven is relatively low due to the large number of enamelled wires to be dried at the same time in the drying tunnel and the mutual influence between adjacent two strands of enamelled wire will not occur, thereby ensuring that the enamelled wire oven with independent drying tunnels has good drying efficiency for enamelled wire.

[0010] Specifically, the painting unit includes a painting member, a starting wheel, an ending wheel, and a paint supply device. The painting member is disposed between the starting wheel and the inlet of the drying tunnel and can paint the wire rod. The ending wheel is disposed at the outlet of the drying tunnel. A wire return channel is formed in the box body along the length direction of the accommodation channel. The wire rod leaving the drying tunnel at the outlet of the drying tunnel can bypass the ending wheel and enter the accommodation channel, and after passing through the accommodation channel, the wire rod can bypass the starting wheel and be painted by the painting member, and then enter the drying tunnel again from the inlet of the drying tunnel. The paint supply device can supply paint to the painting member.

[0011] By adopting the above technical solution, the paint supply device can supply paint to the painting member so that the wire rod is painted when passing through the painting member. When the wire rod passes through the painting member for the first time, enters the drying tunnel and leaves the drying tunnel at the outlet of the drying tunnel, the wire rod can bypass the ending wheel and enter the accommodation channel, and after passing through the accommodation channel, bypass the starting wheel and pass through the painting member again to be painted, and then enter the drying tunnel again from the inlet of the drying tunnel. Thus, multiple painting and drying of the wire rod can be realized by repeating the above process, and high-quality enamelled wire can be produced.

[0012] Further, the painting member includes a painting disc and a felt. The painting disc is provided with a paint groove and a waste liquid groove. The inner wall of the paint groove is provided with paint inlet holes, and the paint supply device is connected to the paint inlet holes. The felt is disposed in the paint groove and can paint the wire rod passing through the notch of the paint groove. The waste liquid groove is located between the paint groove and the drying tunnel, and the waste liquid groove can receive the paint dripping from the wire rod.

[0013] By adopting the above technical solution, the felt can paint the wire rod passing through the notch of the paint groove; the waste liquid groove can receive the paint dripping from the wire rod.

[0014] Further, a plurality of wire receiving grooves are formed in the circumferential direction on the wheel surfaces of the starting wheel and the ending wheel, and the wire rod can enter the wire receiving grooves and abut against the side walls of the wire receiving grooves.

[0015] By adopting the above technical solution, since the wire rods that need to be painted repeatedly will bypass around the starting wheel and the ending wheel repeatedly, the setting of the wire groove can separate these wire rods on the starting wheel and the ending wheel, so that these wire rods will not collide with each other and other situations that will affect the quality of the wire rods will not occur.

[0016] Furthermore, it further includes a lead component. The lead component includes a driving unit and a plurality of lead units. The lead units correspond to the drying tunnels one by one. The lead unit includes a driving wheel, a driven wheel and a lead. The driving wheel is rotatably connected to the rotating shaft of the starting wheel, and the driven wheel is rotatably connected to the rotating shaft of the ending wheel. One end of each lead passes through the corresponding drying tunnel and the wire return groove and is connected to the other end of the lead to form a transmission coil. The transmission coil is sleeved on the driving wheel and the driven wheel and makes the driving wheel and the driven wheel in transmission connection. One end of the wire rod is detachably connected to the transmission coil, and each driving wheel is in transmission connection with the driving unit. The driving unit can independently drive one of the plurality of driving wheels to rotate.

[0017] By adopting the above technical solution, before starting the enameled wire oven with independent drying tunnels, the user needs to wind the wire rods to be processed back and forth between the starting wheel and the ending wheel for multiple turns. The setting of the lead component enables the user to first bundle the wire rods to be wound onto the transmission coil, and then drive the driving wheel corresponding to the transmission coil to rotate through the driving unit, so that the transmission coil can drive the wire rods to be wound to first pass through the drying tunnel, then bypass the ending wheel from top to bottom and pass through the wire return groove, and then bypass the starting wheel from bottom to top and return to the initial position. Thus, the wire rods can be automatically wound through the lead component without manual operation by the user, which is convenient to use.

[0018] Furthermore, the driving unit includes a driving rod, a transmission rod, a driving motor, an outer sleeve and an elastic member. The driving rod and the transmission rod are arranged in parallel at intervals. A plurality of driving wheels are arranged in a row along the length direction of the transmission rod. The driving shaft of the driving motor is connected to one end of the driving rod. The outer sleeve is sleeved on the rod body of the driving rod and is rotatably connected to the box body, and the rotating shaft of the outer sleeve coincides with the rotating shaft of the driving rod. One end of the transmission rod is rotatably connected to the outer sleeve, and a transmission wheel is arranged on the rod body of the transmission rod. One side wheel surface of the transmission wheel abuts against the driving rod, and the transmission wheel can slide along the rod body of the transmission rod and abut against any one of the driving wheels. The elastic member is connected to the outer sleeve and can apply a force to the outer sleeve to drive the transmission rod to turn towards the driving wheel, so that the driving rod is in transmission connection with any one of the driving wheels through the transmission rod and the transmission wheel.

[0019] By adopting the above technical solution, after connecting the wire to be automatically wound around a driving coil, the user can first rotate the outer sleeve to drive the driving rod away from each driving wheel, then move the driving wheel on the driving rod to a position where it abuts against the driving wheel corresponding to the driving coil, and then release the outer sleeve. The elastic member will apply a force to the outer sleeve to drive the driving rod to turn towards the driving wheel, and then make both sides of the driving wheel abut against the driving wheel and the driving rod respectively, so that the driving motor can drive the driving rod, the driving wheel, the driving wheel and the driving coil and the driven wheel corresponding to the driving wheel to rotate, so that the driving coil can automatically wind the wire around it.

[0020] Further, the lead unit further includes a plug pin, a compression spring, a snap spring, a latch rod and a tension spring. A plug pin hole is formed on one side surface of the end wheel close to the corresponding driven wheel. A receiving hole leading to the plug pin hole is formed on the surface of the driven wheel. One end of the plug pin close to the end wheel is inserted into the receiving hole and is clamped with the snap spring. The snap spring can abut against the orifice of the receiving hole close to the end wheel. A clamping groove is formed at the end of the plug pin far from the end wheel. A limiting protrusion is provided on the inner wall of the receiving hole. An abutting protrusion is provided on the rod body of the plug pin. The compression spring is arranged between the limiting protrusion and the abutting protrusion and can apply a force to the plug pin to move it away from the end wheel. The middle of the latch rod is hinged to the driven wheel. The tension spring is arranged between one end of the latch rod and the driven wheel, and the tension spring can drive the other end of the latch rod to rotate towards the direction close to the clamping groove. When the plug pin is inserted into the plug pin hole, the latch rod can be inserted into the clamping groove and abut against the groove wall of the clamping groove close to the plug pin hole.

[0021] By adopting the above technical solution, when using a set of lead units to automatically wind the wire, the user can press the plug pin in the lead unit towards the direction close to the corresponding plug pin hole until the plug pin is inserted into the plug pin hole. At this time, the tension spring will drive the end of the latch rod far from its hinge shaft to rotate towards the direction close to the clamping groove and make the latch rod inserted into the clamping groove, so that the end wheel and the driven wheel can be connected by the plug pin. When the driven wheel and the driving coil drive the wire to bypass the end wheel together, the end wheel can rotate together with the driven wheel and the driving coil, and then the wire will not rub against the surface of the end wheel when bypassing the end wheel, and it is not easy to occur that a certain part of the wire is worn and then broken when bypassing the end wheel, so as to ensure the success rate of the lead unit to automatically wind the wire.

[0022] Further, the lead unit further includes a handwheel and a support rod. One end of the support rod is connected to the wheel surface of the handwheel. A support groove is formed on the edge of the notch of the painting tank. The handwheel is rotatably connected to one side of the corresponding painting disc and can drive the support rod to approach or move away from the support groove. When the support rod abuts against the support groove, the wire connected to the drive coil can abut against the top of the support rod and cross the felt.

[0023] By adopting the above technical solution, when automatically winding the wire using a set of lead units, the user can drive the support rod to approach and abut against the support groove by rotating the handwheel in the lead unit. When the support rod abuts against the support groove, the wire connected to the drive coil can abut against the top of the support rod and cross the felt, so that the felt will not paint the wire when automatically winding the wire using the lead unit.

[0024] Further, the lead unit further includes a wire locking sleeve. The wire locking sleeve is sleeved on the lead wire and can slide along the lead wire. A wire binding gap suitable for accommodating the wire is formed between the lead wire and the inner wall of the wire locking sleeve. When the wire is inserted into the wire binding gap, the wire is abutted between the lead wire and the inner wall of the wire locking sleeve and can limit the wire locking sleeve from sliding along the lead wire.

[0025] By adopting the above technical solution, when automatically winding the wire using a set of lead units, the user can fix the wire on the drive coil by inserting the wire into the wire binding gap of the lead unit; after the coil is automatically wound, the user can pull out the wire from the wire locking sleeve at the end wheel and connect it to the wire receiving device. Since the wire locking sleeve can slide along the lead wire when no wire is inserted, when the wire locking sleeve moves to a position in contact with the driving wheel or the driven wheel, the frictional force exerted by the drive coil on the wire locking sleeve is not sufficient to make the wire locking sleeve bypass the driving wheel or the driven wheel. Thus, the user can drive the drive coil to rotate to bring the wire locking sleeve back to a position close to the starting wheel, facilitating the user to directly connect the wire to the wire locking sleeve at the starting wheel when the set of lead units is needed to automatically wind the wire next time.

[0026] Further, the wire locking sleeve includes a clamping member and a receiving member. One end of the clamping member is provided with a clamping protrusion. The other end of the clamping member is hinged to one end of the receiving member. The other end of the receiving member is provided with a clamping groove. The clamping protrusion can be inserted into the clamping groove to be clamped with the inner wall of the clamping groove and make the clamping member and the receiving member fit together to form the wire locking sleeve.

[0027] By adopting the above technical solution, the clamping member and the receiving member can be clamped and fitted together through the cooperation of the clamping protrusion and the clamping groove, and the lead wire is abutted and fixed in the wire locking sleeve formed by the clamping and fitting of the clamping member and the receiving member.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. It includes a box body, a painting assembly and a heat source. A receiving through groove is formed on the box body. A plurality of partition plates are arranged in parallel and at intervals on the groove wall of the receiving through groove, and the receiving through groove is divided into a plurality of drying channels by the plurality of partition plates. The painting assembly includes a plurality of painting units, and the drying channels correspond to the painting units one by one. Each painting unit can paint a single wire passing through it. Each drying channel is communicated with the air outlet of the heat source, so that each drying channel can dry the wire painted by the corresponding painting unit. The setting of multiple drying channels for multiple wires enables the enamelled wire oven with independent drying channels to independently dry a single wire in each drying channel, rather than drying multiple strands of enamelled wire simultaneously in an entire drying channel. Therefore, the situation where the drying efficiency of the enamelled wire oven is low due to the mutual influence of adjacent two strands of enamelled wire when the number of enamelled wires to be dried in the drying channel at the same time is large will not occur, thus ensuring that the enamelled wire oven with independent drying channels has good drying efficiency for enamelled wire;

[0030] 2. The lead-in assembly includes a driving unit and a plurality of lead-in units. The lead-in units correspond to the drying channels one by one. Each lead-in unit includes a driving wheel, a driven wheel and a lead-in wire. The driving wheel is rotatably connected to the rotating shaft of the starting wheel, and the driven wheel is rotatably connected to the rotating shaft of the ending wheel. One end of each lead-in wire passes through the corresponding drying channel and the wire-return through groove and is connected to the other end of the lead-in wire to form a transmission coil. The transmission coil is sleeved on the driving wheel and the driven wheel and makes the driving wheel and the driven wheel in transmission connection. One end of the wire is detachably connected to the transmission coil. Each driving wheel is in transmission connection with the driving unit. The driving unit can independently drive one of the plurality of driving wheels to rotate. Before starting the enamelled wire oven with independent drying channels, the user needs to first wind the wire to be processed back and forth between the starting wheel and the ending wheel for multiple turns. The setting of the lead-in assembly enables the user to first bundle the wire to be wound onto the transmission coil, and then drive the driving wheel corresponding to the transmission coil to rotate through the driving unit, so that the transmission coil can drive the wire to be wound to first pass through the drying channel, then bypass the ending wheel from top to bottom and pass through the wire-return through groove, and then bypass the starting wheel from bottom to top and return to the initial position. Therefore, the wire can be automatically wound through the lead-in assembly without manual operation by the user, which is convenient to use. Description of the Drawings

Detailed implementation manners

[0042] The following is further described in conjunction with the attached Figures 1 - 10 for further illustration:

[0043] SeeFigure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 10 , a enamelled wire oven with an independent drying channel, which is used to process wire 3 into enamelled wire. Specifically, it includes a box body 1, a painting assembly 2, a heat source (not shown in the figure), an annealing furnace (not shown in the figure) and a lead wire assembly 4. An annealing through groove 14, a wire return through groove 13 and a receiving through groove are arranged in the box body 1 from bottom to top. The annealing through groove 14, the wire return through groove 13 and the receiving through groove are all opened along the length direction of the box body 1. The annealing furnace is arranged in the annealing through groove 14. The inlets of the annealing through groove 14 and the wire return through groove 13 and the outlet of the receiving through groove are all located on the same side of the box body 1. The outlets of the annealing through groove 14 and the wire return through groove 13 and the inlet of the receiving through groove are all located on the other side of the box body 1. Five partition plates 11 are arranged in parallel at intervals on the groove wall of the receiving through groove. These partition plates 11 divide the receiving through groove into six drying channels 12. The heat source can be a hot air blower. Each drying channel 12 is communicated with the air outlet of the hot air blower, so that each drying channel 12 can independently dry a wire 3. The painting assembly 2 includes six painting units 21. The six drying channels 12 correspond to the six painting units 21 one by one. Each painting unit 21 can paint a single wire 3 passing through it. Then, the enamelled wire oven with an independent drying channel can simultaneously and independently dry six wires 3 in the six drying channels 12, without drying multiple strands of enamelled wire simultaneously in a whole drying channel 12. Therefore, there will be no situation where the number of enamelled wires to be dried in the drying channel 12 at the same time is large, and the adjacent two strands of enamelled wire affect each other, resulting in a low drying efficiency of the enamelled wire oven. Thus, it can ensure that the enamelled wire oven with an independent drying channel has a good drying efficiency for the enamelled wire.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 10Each painting unit 21 includes two starting wheels 212, an end wheel 213, a paint tray 211 and a paint supply device 214. The two starting wheels 212 are arranged up and down, and the starting wheel 212 located at the bottom is arranged at the outlet of the return channel. The paint tray 211 is arranged between the starting wheel 212 located at the top and the inlet of the drying tunnel 12. The end wheel 213 is arranged at the outlet of the drying tunnel 12.

The paint supply device 214 can be a metering pump. The liquid outlet of the metering pump is connected to the paint inlet hole through a pipeline. The liquid inlet of the metering pump is connected to the paint storage tank storing paint through a pipeline. , so that the paint supply device 214 can supply paint into the paint tank 2111; a felt (not shown in the figure) can be arranged in the paint tank 2111, so that the wire 3 passing through the notch of the paint tank 2111 can be painted by the felt, and the waste liquid tank 2112 is located between the paint tank 2111 and the entrance of the drying tunnel 12 and can receive the paint dripping from the wire 3; a plurality of wire receiving grooves for accommodating the wire 3 are circumferentially provided on the wheel surface of each starting wheel 212 and the end wheel 213, and each time the wire 3 passes around the starting wheel 212 or the end wheel 213, the user can manually move the wire 3, so that each circle of the wire 3 on the starting wheel 212 and the end wheel 213 is located in an independent wire receiving groove.

[0045] The processing process of the wire 3 by the enameled wire oven with independent drying channel described in the present application is as follows:

[0046] When a wire 3 leaves the feeding device, it will first enter the annealing groove 14 from the entrance of the annealing groove 14 and be baked by the annealing furnace, then leave the annealing groove 14 from the exit and wind upward around the starting wheel 212 located near the paint plate 211, then move horizontally and pass through the paint tank 2111, the waste liquid tank 2112, the entrance of the drying tunnel 12 and the exit of the drying tunnel 12 in sequence, then go around the terminal wheel 213 downward and pass through the return groove 13 to the starting wheel 212 located near the exit of the return groove 13, finally go around the starting wheel 212 upward and come to the starting wheel 212 located near the paint plate 211. At this time, it can be regarded as having undergone a painting and baking process on the wire 3, and the end of the wire 3 is just at The wire 3 is wound once on the circular route formed by the two starting wheels 212 and the end wheel 213; since each wire 3 needs to undergo 4-10 times of painting and baking after being processed into a finished enameled wire, taking 4 times as an example, the user can wind the wire 3 three times on the circular route formed by the two starting wheels 212 and the end wheel 213, and connect the wire 3 to a winding device such as a winder after the wire 3 passes through the drying tunnel 12 along the circular path for the fourth time; since the wire 3 that needs to be repeatedly painted will repeatedly bypass the starting wheel 212 and the end wheel 213, the setting of the wire receiving groove can separate these wires 3 on the starting wheel 212 and the end wheel 213, so that there will be no collision between these wires 3, which will affect the quality of the wire 3.

A tying gap suitable for accommodating the wire 3 is formed between the lead 4203 and the inner wall of the wire-locking sleeve. The wire-locking sleeve can be made of a material with a certain elasticity such as rubber, so that the user can connect the wire 3 to the drive coil by inserting the wire 3 into the tying gap. When the wire-locking sleeve is not connected to the wire 3, the wire-locking sleeve can slide along the two parallel leads 4203. The handwheel 4209 is rotatably connected to one side of the corresponding painting plate 211. A support groove 2113 is provided on the other side of the painting plate 211.

The driving shaft of the driving motor 413 passes through the inner sleeve 4141 and is connected to one end of the driving rod 411. The outer sleeve 414 is sleeved on the driving rod 411 and the inner sleeve 4141 and is rotatably connected to the inner sleeve 4141 through a bearing. And the rotation axis of the outer sleeve 414 coincides with the rotation axis of the driving rod 411. One end of the transmission rod 412 is rotatably connected to the outer sleeve 414. And three transmission wheels 4121 are arranged on the rod body of the transmission rod 412. One side surface of each transmission wheel 4121 abuts against the driving rod 411. And each transmission wheel 4121 can slide along the rod body of the transmission rod 412 and abut against any one of the driving wheels 4201. The elastic member 415 is connected to the outer sleeve 414 and can apply a force to the outer sleeve 414 to drive the transmission rod 412 to turn towards the driving wheel 4201, so that the driving rod 411 is in transmission connection with any three driving wheels 4201 through the transmission rod 412 and the transmission wheels 4121.

[0051] After a wire 3 from the feeding device is passed through the annealing through groove 14 and pulled out of the outlet of the annealing through groove 14 to the outside of the annealing through groove 14, the user needs to repeatedly wind the wire 3 around the circular route formed by the two starting wheels 212 and the ending wheels 213 according to the number of times of painting and baking processes that the wire 3 needs to experience when processed into an enameled wire finished product. Taking 4 times as an example, the using process of the lead assembly 4 of an enameled wire oven with an independent baking channel described in the present application is as follows:

[0052] S1. Move the end of the wire 3 upward and wind it around the starting wheel 212 near the painting tray 211. Then fix the end of the wire 3 on the driving coil by using a wire locking sleeve. Then first rotate the outer sleeve 414 to drive the transmission rod 412 to turn away from each driving wheel 4201. Then move the transmission wheel 4121 on the transmission rod 412 to a position where it abuts against the driving wheel 4201 corresponding to the driving coil. Then release the outer sleeve 414. The elastic member 415 will apply a force to the outer sleeve 414 to drive the transmission rod 412 to turn towards the driving wheel 4201. Subsequently, both sides of the transmission wheel 4121 abut against the driving wheel 4201 and the driving rod 411 respectively. Thus, the driving motor 413 can drive the driving rod 411, the transmission wheel 4121, the driving wheel 4201 and the driving coil and the driven wheel 4202 corresponding to the driving wheel 4201 to rotate, so that the driving coil can automatically wind the wire 3.

[0053] S2. After the driving wheel 4201 of a set of lead units 42 is abutted against the transmission wheel 4121, the user can rotate the handwheel 4209 in the lead unit 42 to a position where the support rod 4210 abuts against the support groove 2113, so as to be able to use the support rod 4210 to separate the wire 3 and the felt, so that the felt will not paint the wire 3 when automatically winding the wire 3 by using the lead unit 42;

[0054] S3. Press the pin 4204 in each of the lead units 42 to be used towards the direction of the corresponding pin hole until the pin 4204 is inserted into the pin hole. At this time, the tension spring 4208 will drive the end of the latch 4207 away from its hinge shaft to rotate towards the direction of the card slot and make the latch 4207 inserted into the card slot, so that the end wheel 213 and the driven wheel 4202 can be connected through the pin 4204. When the driven wheel 4202 and the drive coil drive the wire 3 to bypass the end wheel 213 together, the end wheel 213 can rotate together with the driven wheel 4202 and the drive coil, and then the wire 3 will not rub against the surface of the end wheel 213 when bypassing the end wheel 213, and it is not easy for a certain part of the wire 3 to be worn and then broken when bypassing the end wheel 213. Therefore, the success rate of the lead unit 42 automatically winding the wire 3 can be guaranteed;

[0055] S4. Start the drive motor 413 to drive the rotation of the drive wheels 4201 corresponding to the drive coils each connected with the wire 3, so that the drive coil can first drive the wire 3 to be wound through the drying channel 12, then bypass the end wheel 213 from top to bottom and pass through the return wire through groove 13, and then bypass the two starting wheels 212 from bottom to top and return to the initial position. After repeating this three times, when the end of the wire 3 driven by the drive coil fourthly passes out of the drying channel 12 from the outlet of the drying channel 12, turn off the drive motor 413, and remove the end of the wire 3 from each drive coil and connect it to a wire collecting device such as a winding machine;

[0056] S5. First, move the end of the clamping rod 4207 away from its hinge axis in a direction away from the card slot, so that the bolt 4204 leaves the bolt hole under the action of the compression spring 4205. Then, rotate the handwheel 4209 in each lead unit 42 until the top of the rod body of the support rod 4210 is lower than the position of the felt in the painting tank 2111. Next, start the drive motor 413 to drive each drive coil to rotate in a direction opposite to the rotation direction when driving the wire 3. Since the wire locking sleeve can slide along the lead 4203 when the wire 3 is not inserted, when the wire locking sleeve moves to a position in contact with the drive wheel 4201 or the driven wheel 4202, the frictional force applied by the drive coil to the wire locking sleeve is not sufficient to make the wire locking sleeve bypass the drive wheel 4201 or the driven wheel 4202. Thus, the user can drive the drive coil to rotate to bring the wire locking sleeve back to a position close to the starting wheel 212, which is convenient for the user to directly connect the wire 3 to the wire locking sleeve at the starting wheel 212 when the wire 3 needs to be automatically wound by this set of lead units 42 next time.

[0057] The implementation principle of the enameled wire oven with an independent drying tunnel described in this application is as follows:

[0058] Inside the box body 1, an annealing through slot 14, a wire return through slot 13, and a receiving through slot are provided from bottom to top. The annealing through slot 14, the wire return through slot 13, and the receiving through slot are all opened along the length direction of the box body 1. The annealing furnace is arranged in the annealing through slot 14. The inlets of the annealing through slot 14 and the wire return through slot 13 and the outlet of the receiving through slot are all located on the same side of the box body 1, and the outlets of the annealing through slot 14 and the wire return through slot 13 and the inlet of the receiving through slot are all located on the other side of the box body 1; Five partition plates 11 are arranged in parallel at intervals on the wall of the receiving through slot. These partition plates 11 divide the receiving through slot into six drying tunnels 12. The heat source can be a hot air blower, and each drying tunnel 12 is communicated with the air outlet of the hot air blower, so that each drying tunnel 12 can independently dry a wire 3; The painting assembly 2 includes six painting units 21. The six drying tunnels 12 correspond to the six painting units 21 one by one. Each painting unit 21 can paint a single wire 3 passing through it. Then, the enameled wire oven with an independent drying tunnel can simultaneously and independently dry six wires 3 in the six drying tunnels 12, without drying multiple enameled wires simultaneously in an entire drying tunnel 12. Therefore, there will be no situation where the number of enameled wires to be dried in the drying tunnel 12 at the same time is large, and the adjacent two enameled wires affect each other, resulting in a low drying efficiency of the enameled wire oven. Thus, it can ensure that the enameled wire oven with an independent drying tunnel has a good drying efficiency for the enameled wire.

[0059] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
