Description

Technical Field

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

[0002] Existing enameled wire ovens generally have a painting device at the inlet end of the drying tunnel. The wire material to be processed into the enameled wire will first pass through the painting device and be painted on the surface of the wire material by the painting device, then pass through the drying tunnel and be dried by the drying device, and then return to the painting device to be painted again, and finally obtain the finished enameled wire after multiple painting and drying.

[0003] However, since the drying tunnel in the current enameled wire drying oven is an integral drying tunnel that can be used to dry multiple enameled wires at the same time, the heat source of the enameled wire drying oven is to blow hot air into the integral drying tunnel to dry the enameled wires in the integral drying tunnel. When a large number of enameled wires need to be dried at the same time, two adjacent enameled wires are likely to affect each other, reducing the drying efficiency of both, thereby making the drying efficiency of the enameled wire drying oven low.

[0004] In view of this, it is necessary to provide an enameled wire oven with an independent baking channel. Summary of the invention

[0005] In order to solve the problem that the drying channel in the existing enameled wire drying oven is an integral drying channel and the drying efficiency is low when drying multiple strands of enameled wires at the same time, the present application provides an enameled wire drying oven with an independent drying channel.

[0006] The present application provides an enameled wire oven with independent drying channels, which adopts the following technical solution: comprising a box body, a painting assembly and a heat source, wherein the box body is provided with a receiving slot, a plurality of partitions are arranged on the slot wall of the receiving slot in parallel and at intervals, and the receiving slot is divided into a plurality of drying channels by the plurality of partitions; The painting assembly includes a plurality of painting units, the drying tunnel corresponds to the painting units one by one, and each of the painting units can paint a single wire passing through it; Each of the drying channels is communicated with the air outlet of the heat source, so that each of the drying channels can dry the wires painted by the corresponding painting unit.

[0007] By adopting the above technical solution, the arrangement of multiple drying channels for multiple wires enables the enameled wire oven with independent drying channels to independently dry a single wire in each drying channel, without the need to simultaneously dry multiple strands of enameled wire in the entire drying channel. This also prevents the situation where a large number of enameled wires that need to be dried in the drying channel at the same time affect each other, resulting in a low drying efficiency of the enameled wire oven. This ensures that the enameled wire oven with independent drying channels has good drying efficiency for the enameled wire.

[0008] Specifically, the painting unit includes a paint coating member, a starting wheel, an end wheel and a paint supply device. The paint coating member is arranged between the starting wheel and the inlet of the drying tunnel and can paint the wire. The end wheel is arranged at the outlet of the drying tunnel. A return groove is opened on the box body along the length direction of the accommodating groove. The wire leaving the drying tunnel from the outlet of the drying tunnel can bypass the end wheel and enter the accommodating groove. After passing through the accommodating groove, the wire can bypass the starting wheel to be painted by the paint coating member and enter the drying tunnel from the inlet of the drying tunnel again. The paint supply device can supply paint to the paint coating member.

[0009] By adopting the above technical solution, the paint supply device can supply paint to the painted part, so that the wire is painted when passing through the painted part; and when the wire passes through the painted part for the first time, enters the drying tunnel and leaves the drying tunnel from the outlet of the drying tunnel, the wire can bypass the end wheel and enter the accommodating groove, and after passing through the accommodating groove, bypass the starting wheel and pass through the painted part again to be painted, and then enter the drying tunnel again from the inlet of the drying tunnel, so that the wire can be painted and dried multiple times by repeating the above process, and high-quality enameled wire can be produced.

[0010] Furthermore, the painted part includes a paint tray and a felt, the paint tray is provided with a paint trough and a waste liquid trough, the inner wall of the paint trough is provided with a paint inlet hole, the paint supply device is connected to the paint inlet hole, the felt is arranged in the paint trough and can paint the wire passing through the notch of the paint trough, the waste liquid trough is located between the paint trough and the drying tunnel, and the waste liquid trough can receive the paint dripping from the wire.

[0011] By adopting the above technical solution, the felt can paint the wires passing through the notch of the paint tank; and the waste liquid tank can receive the paint dripping from the wires.

[0012] Furthermore, a plurality of wire receiving grooves are circumferentially formed on the wheel surfaces of the starting wheel and the ending wheel, and the wires can enter the wire receiving grooves and abut against the side walls of the wire receiving grooves.

[0013] By adopting the above technical solution, since the wires that need to be repeatedly painted will repeatedly pass around the starting wheel and the end wheel, the setting of the wire receiving groove can separate these wires on the starting wheel and the end wheel, so that there will be no collision between these wires, which will affect the quality of the wires.

[0014] Furthermore, it also includes a lead assembly, which includes a driving unit and multiple lead units, and the lead units correspond to the drying tunnels one by one. The lead units include 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 end wheel. One end of each lead passes through the corresponding drying tunnel and the return wire 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 to make the driving wheel and the driven wheel transmission connected. One end of the wire is detachably connected to the transmission coil, and each driving wheel is transmission connected to the driving unit. The driving unit can independently drive one of the multiple driving wheels to rotate.

[0015] By adopting the above technical solution, before starting the enameled wire oven with an independent drying tunnel, the user needs to first wind the wire to be processed back and forth between the starting wheel and the end wheel for multiple turns, and the setting of the lead assembly allows 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 carry the wire to be wound through the drying tunnel first, then bypass the end wheel from top to bottom and pass through the return wire slot, and then bypass the starting wheel from bottom to top to return to the initial position, so that the wire can be automatically wound by the lead assembly without the need for manual operation by the user, which is convenient to use.

[0016] Furthermore, the driving unit includes a driving rod, a transmission rod, a driving motor, a jacket and an elastic member, the driving rod and the transmission rod are arranged in parallel and at intervals, and 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 jacket is mounted on the rod body of the driving rod and is rotatably connected to the box, and the rotating shaft of the jacket coincides with the rotating shaft of the driving rod, one end of the transmission rod is rotatably connected to the jacket, and a transmission wheel is provided 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 of the driving wheels, the elastic member is connected to the jacket and can apply a force to the jacket to drive the transmission rod to turn to the driving wheel, so that the driving rod is transmission-connected to any of the driving wheels via the transmission rod and the transmission wheel.

[0017] By adopting the above technical solution, after the wire to be automatically wound is connected to a transmission coil, the user can first rotate the outer sleeve to drive the transmission rod to turn away from each driving wheel, and then move the transmission wheel on the transmission rod to a position abutting the driving wheel corresponding to the transmission coil, and then loosen the outer sleeve, the elastic member will apply a force to the outer sleeve to drive the transmission rod to turn toward the driving wheel, and then make the two sides of the transmission wheel abut against the driving wheel and the driving rod respectively, so that the driving motor can drive the driving rod, the transmission wheel, the driving wheel and the transmission coil and the driven wheel corresponding to the driving wheel to rotate, so that the transmission coil can automatically wind the wire.

[0018] Furthermore, the lead unit also includes a latch, a compression spring, a retaining spring, a clamping rod and a tension spring. A latch hole is provided on a wheel surface of the end wheel close to the corresponding driven wheel, and a receiving hole leading to the latch hole is provided on the wheel surface of the driven wheel. One end of the latch close to the end wheel is inserted into the receiving hole and clamped with the retaining spring. The retaining spring can abut against a hole on one side of the receiving hole close to the end wheel. A clamping groove is provided on the end of the latch away from the end wheel, and a limiter is provided on the inner wall of the receiving hole. The rod of the latch is provided with a contact protrusion, the compression spring is arranged between the limiting protrusion and the contact protrusion and can apply a force to the latch to move away from the end wheel, the middle part of the clamping rod is hinged on the driven wheel, the tension spring is arranged between one end of the clamping rod and the driven wheel, and the tension spring can drive the other end of the clamping rod to rotate toward the direction close to the clamping slot, and when the latch is inserted into the latch hole, the clamping rod can be inserted into the latch slot and abut against a side groove wall of the latch slot close to the latch hole.

[0019] By adopting the above technical solution, when using a group of lead units to automatically wind the wire, the user can press the pin in the lead unit towards the direction close to the corresponding pin hole until the pin is inserted into the pin hole. At this time, the tension spring will drive the end of the clamping rod away from its own hinge axis to rotate towards the direction close to the clamping slot and insert the clamping rod into the clamping slot, so that the terminal wheel and the driven wheel can be connected by the pin, so that when the driven wheel and the transmission coil drive the wire to bypass the terminal wheel together, the terminal wheel can rotate together with the driven wheel and the transmission coil, and then the wire will not rub against the surface of the terminal wheel when bypassing the terminal wheel, and it is not easy for a part of the wire to be worn and then broken when bypassing the terminal wheel, thereby ensuring the success rate of automatic winding of the wire by the lead unit.

[0020] Furthermore, the lead unit also 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 opened on the edge of the groove of the paint groove, the handwheel is rotatably connected to one side of the corresponding paint plate and can drive the support rod close to or away from the support groove, when the support rod abuts against the support groove, the wire connected to the transmission coil can abut against the top of the support rod and pass over the felt.

[0021] By adopting the above technical solution, when using a group of lead units to automatically wind the wire, the user can drive the support rod to approach and abut the support groove by rotating the hand wheel in the lead unit. When the support rod abuts the support groove, the wire connected to the transmission coil can abut the top of the support rod and pass over the felt, thereby preventing the felt from painting the wire when the lead unit is used to automatically wind the wire.

[0022] Furthermore, the lead unit also includes a wire locking sleeve, which is sleeved on the lead and can slide along the lead, and a wire binding gap suitable for accommodating the wire is formed between the lead 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 and the inner wall of the wire locking sleeve and can limit the wire locking sleeve from sliding along the lead.

[0023] By adopting the above technical solution, when using a group of lead units to automatically wind the wire, the user can fix the wire on the transmission coil by inserting the wire into the wire binding gap of the lead unit; after the coil is automatically wound, the user can pull the wire out of the wire locking sleeve at the end wheel and connect it to the wire taking-up device, and because the wire locking sleeve can slide along the lead 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 friction force applied by the transmission coil to the wire locking sleeve is not enough to make the wire locking sleeve bypass the driving wheel or the driven wheel, so that the user can drive the transmission coil to rotate to bring the wire locking sleeve back to a position close to the starting wheel, so that the user can directly connect the wire to the wire locking sleeve at the starting wheel when the group of lead units is needed to automatically wind the wire next time.

[0024] Furthermore, the locking wire sleeve includes a clamping part and a receiving part, one end of the clamping part is provided with a clamping protrusion, the other end of the clamping part is hinged to one end of the receiving part, and the other end of the receiving part is provided with a clamping groove, the clamping protrusion can be inserted into the clamping groove and clamped with the inner wall of the clamping groove to make the clamping part and the receiving part assembled to form the locking wire sleeve.

[0025] By adopting the above technical solution, the clamping member and the receiving member can be spliced ​​together through the cooperating clamping of the clamping protrusion and the clamping groove, and the lead wire can be abutted and fixed in the wire locking sleeve formed by the splicing of the clamping member and the receiving member.

The box body is provided with a receiving slot. A plurality of partitions are arranged on the slot wall of the receiving slot in parallel and at intervals. The receiving slot is divided into a plurality of drying channels by the plurality of partitions. The painting component includes a plurality of painting units. 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 connected to the air outlet of the heat source so that each drying channel can dry the wire painted by the corresponding painting unit. The arrangement of the plurality of drying channels for the plurality of wires enables the enameled wire oven with independent drying channels to independently dry a single wire in each drying channel without drying a plurality of enameled wires in the entire drying channel at the same time. Therefore, when a large number of enameled wires need to be dried in the drying channel at the same time, the two adjacent enameled wires will not affect each other, resulting in a low drying efficiency of the enameled wire oven. This ensures that the enameled wire oven with independent drying channels has good drying efficiency for the enameled wires. 2. The lead assembly includes a driving unit and a plurality of lead units. The lead units correspond to the drying tunnels one by one. The lead units include 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 terminal wheel. One end of each lead passes through the corresponding drying tunnel and the return wire slot 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 the driving wheel is connected to the driven wheel. One end of the wire is detachably connected to the transmission coil. Each driving wheel is connected to the driving unit. The driving unit can independently drive one of the plurality of driving wheels to rotate. Before starting the enameled wire oven with an independent drying tunnel, the user needs to wind the wire to be processed back and forth between the starting wheel and the end wheel for multiple turns. The setting of the lead assembly allows the user to first bundle the wire to be wound onto the transmission coil, and then drive the drive wheel corresponding to the transmission coil to rotate through the drive unit, so that the transmission coil can carry the wire to be wound through the drying tunnel first, then bypass the end wheel from top to bottom and pass through the return wire slot, and then bypass the starting wheel from bottom to top and return to the initial position, so that the wire can be automatically wound through the lead assembly without the need for manual operation by the user, which is convenient to use.

The rotating axis of the sleeve 414 coincides with the rotating 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 provided on the rod body of the transmission rod 412, one side of the wheel surface of each transmission wheel 4121 is in contact with the driving rod 411, and each transmission wheel 4121 can slide along the rod body of the transmission rod 412 and abut against any driving wheel 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 toward the driving wheel 4201, so that the driving rod 411 is transmission-connected to any three driving wheels 4201 via the transmission rod 412 and the transmission wheel 4121.

[0036] After a wire 3 from the feeding device passes through the annealing groove 14 and is pulled out from the outlet of the annealing groove 14 to the outside of the annealing groove 14, the user needs to repeatedly wind the wire 3 around the circular route formed by the two starting wheels 212 and the end wheel 213 according to the number of times the wire 3 needs to undergo painting and baking when it is processed into an enameled wire product; taking 4 times as an example, the use process of the lead assembly 4 of the enameled wire oven with an independent baking channel described in the present application is as follows: S1, move the end of the wire 3 upward and wind it around the starting wheel 212 located near the paint plate 211, then use the wire locking sleeve to fix the end of the wire 3 on the transmission coil, then 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 abutting against the driving wheel 4201 corresponding to the transmission coil, then loosen 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 to the driving wheel 4201, and then make the two sides of the transmission wheel 4121 abut against the driving wheel 4201 and the driving rod 411 respectively, so that 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 transmission coil can automatically wind the wire 3; S2. After the driving wheel 4201 of a set of lead wire units 42 is brought into contact with the transmission wheel 4121, the user can rotate the hand wheel 4209 in the lead wire unit 42 to a position where the support rod 4210 is brought into contact with the support groove 2113, so that the support rod 4210 can be used to separate the wire 3 and the felt, so that the felt will not paint the wire 3 when the lead wire unit 42 is used to automatically wind the wire 3; S3, press the latch 4204 in each lead unit 42 to be used in the direction close to the corresponding latch hole until the latch 4204 is inserted into the latch hole, at which time the tension spring 4208 will drive the end of the clamping rod 4207 away from its own hinge axis to rotate in the direction close to the clamping slot and insert the clamping rod 4207 into the clamping slot, so that the terminal wheel 213 and the driven wheel 4202 can be connected through the latch 4204, so that when the driven wheel 4202 and the transmission coil drive the wire 3 to bypass the terminal wheel 213 together, the terminal wheel 213 can rotate together with the driven wheel 4202 and the transmission coil, and then the wire 3 will not rub against the surface of the terminal wheel 213 when bypassing the terminal wheel 213, and it is not easy for a part of the wire 3 to be worn and then broken when bypassing the terminal wheel 213, thereby ensuring the success rate of the lead unit 42 automatically winding the wire 3; S4, start the driving motor 413 to drive the driving wheels 4201 corresponding to the transmission coils connected to the wires 3 to rotate, so that the transmission coils can first carry the wires 3 to be wound through the drying tunnel 12, then bypass the end wheel 213 from top to bottom and pass through the return wire slot 13, and then bypass the two starting wheels 212 from bottom to top to return to the initial position. After repeating this three times, when the transmission coil carries the end of the wire 3 out of the drying tunnel 12 from the exit of the drying tunnel 12 for the fourth time, turn off the driving motor 413, and remove the end of the wire 3 from each transmission coil and connect it to a winding device such as a winding machine; S5. First, move the end of the clamping rod 4207 away from the hinge axis in the direction away from the clamping slot, so that the latch 4204 leaves the latch hole under the action of the compression spring 4205. Then, rotate the hand wheel 4209 in each lead unit 42 to make the top of the rod body of the support rod 4210 lower than the felt in the paint tank 2111. Then, start the drive motor 413 to drive each transmission coil to rotate in the opposite direction to the rotation direction when driving the wire 3. Since the wire lock sleeve can rotate along the lead when the wire 3 is not inserted, 4203 slides, and when the wire locking sleeve moves to a position in contact with the driving wheel 4201 or the driven wheel 4202, the friction force applied by the transmission coil to the wire locking sleeve is insufficient to allow the wire locking sleeve to bypass the driving wheel 4201 or the driven wheel 4202, so that the user can drive the transmission coil to rotate to bring the wire locking sleeve back to a position close to the starting wheel 212, so that the next time the group of lead units 42 is needed to automatically wind the wire 3, the user can directly connect the wire 3 with the wire locking sleeve at the starting wheel 212.
