Description

Technical Field

[0001] The invention relates to the technical field of enameled wire processing equipment, in particular to a drying and cooling device for enameled wire processing. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, then painted and baked for many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a preheating mechanism, the air inside the piston sleeve is heated by an electric heating wire, and the heat can be gathered inside the sealed expansion airbag. The expansion airbag is initially expanded and attached to the outer wall of the enameled wire, so that the heat inside the expansion airbag can be transferred to the enameled wire, and the surface of the enameled wire entering the dryer can be preheated. The enameled wire usually has a coating or paint layer, which is very sensitive to temperature changes. If directly exposed to high temperatures, thermal shock is prone to occur, causing the coating to crack or peel off. The expansion airbag is expanded and attached to the outer wall of the enameled wire, which can avoid the thermal shock effect of direct contact with high temperature to a certain extent, making the temperature change more gentle and reducing the risk of coating damage, thereby avoiding the enameled wire directly entering the high-temperature dryer for drying, causing cracks, bubbling or shedding of the surface coating, thereby improving the molding effect of the enameled wire after drying;

[0016] 2. By setting up the coordination of bevel gears and other parts, when the enameled wire enters the dryer for drying, the drive motor is started, and the output end of the drive motor drives the connecting shaft to drive the bevel gear to rotate in a circle, and then drives the bevel gear ring to drive the expansion airbag to rotate in a circle through the sealing ring, so as to continuously adjust the contact position with the enameled wire, so that the heat distribution is more uniform, avoiding the problem of local overheating or overcooling, and avoiding the thermal shock that may be caused by direct heating. The surface coating of the enameled wire can be dried in a milder environment, avoiding the peeling or cracking of the coating due to excessive temperature difference, thereby further improving the drying effect of the enameled wire;

[0017] 3. By setting a reciprocating suction device, when the connecting shaft rotates in a circle, the inclined block is also driven to rotate in a circle. When the contact position between the top of the inclined block and the spherical rod rotates from the highest point to the lowest point, the pressure on the spherical rod gradually decreases, so that the connecting spring pushes the piston block to move downward to push the hot air inside the piston sleeve into the expansion airbag, so that the expansion airbag gradually expands. When the contact position between the inclined block and the spherical rod rotates from the lowest point to the highest point, the spherical rod is pushed to drive the piston block to move upward to inhale the inside of the expansion airbag. The inclined block rotates continuously, so that the piston block moves continuously to form reciprocating suction on the inside of the expansion airbag, thereby making the expansion air The balloon can expand and contract reciprocatingly. The expansion and contraction help the hot air to be transferred to each part of the expansion balloon more evenly, so that the contact between the surface of the expansion balloon and the surface of the enameled wire is more even, avoiding local overheating or overcooling. The expansion and contraction of the expansion balloon ensures that it can always maintain appropriate contact pressure with the outer wall of the enameled wire, which helps to ensure that the transfer of heat and airflow is not hindered. The gas in the expansion balloon is constantly renewed through the process of suction and exhaust, which can prevent overheating or moisture accumulation, and ensure that the air inside the expansion balloon is always kept in a suitable state, thereby improving the drying efficiency, thereby further improving the effect of preheating the surface of the enameled wire;

[0018] 4. By setting up the coordination of spur gears and other parts, when a sliding rod pushes a piston block to move downward to inflate the inside of an expansion airbag, a spur gear is driven to rotate by a spur rack, and then another spur rack is driven to drive another piston block to move upward to inhale the inside of another expansion airbag, so that one expansion airbag is expanded while the other is contracted. The alternating expansion and contraction can ensure that the heat is evenly distributed in the expansion airbag and is transferred to the surface of the enameled wire through the contact between the expansion airbag and the enameled wire. This uniform heat distribution helps to preheat the expansion airbag, so that it gradually adapts to the temperature entering the dryer, and avoids coating problems caused by excessive temperature differences;

[0019] 5. By setting a suction adjustment part, when it is necessary to adjust the expansion force of the expansion airbag, the staff can manually rotate the first one-way threaded screw to drive the movable block to drive the spherical rod to move upward, so as to adjust the height of the spherical rod, and then rotate the second one-way threaded screw to drive the L-shaped seat to drive the spherical rod to move horizontally, so as to adjust the distance between the spherical rod and the highest point of the top slope of the inclined block, so as to adjust the distance that the spherical rod is pushed, thereby realizing the control of the amount of gas inflated inside the expansion airbag, so that the pressure applied to the enameled wire by the expansion airbag during the expansion process is maintained in an appropriate range, avoiding over-expansion or under-expansion, thereby affecting the uniform drying of the coating, and at the same time, it can realize preheating of enameled wires of different thicknesses, thereby improving the overall practicality of the device.

[0031] Example 1

[0032] See also Figures 1 to 8The present embodiment provides a drying and cooling device for enameled wire processing, comprising: a winding machine 1, a drying machine 2 and a cooling box 3, wherein a preheating tube 4 passes through the interior of the drying machine 2 and the cooling box 3; a preheating mechanism, comprising a preheating tube 4 arranged at the feed inlet of the drying machine 2, wherein two expansion air bags 6 are arranged inside the preheating tube 4, and the preheating mechanism comprises two piston sleeves 8 fixedly connected to the top of the preheating tube 4, wherein a sealing ring 7 is rotatably connected to the inner side of the preheating tube 4, and an annular groove 17 is provided on the inner side of the sealing ring 7, wherein the annular groove 17 is communicated with the interior of the piston sleeve 8, and an air guide tube 18 is fixedly connected to the air inlet of the expansion air bag 6, and the ... One end of the tube 18 penetrates the inner side of the sealing ring 7 and communicates with the annular groove 17, an electric heating wire 16 is installed on the inner side of the piston sleeve 8, and the preheating mechanism also includes a connecting seat 9 fixedly connected to one end of the preheating tube 4, a driving motor 10 is installed on the inner side of the connecting seat 9, a connecting shaft 11 is connected to the output end of the driving motor 10, and one end of the connecting shaft 11 penetrates the inner side of the preheating tube 4 and is rotatably connected to the preheating tube 4, a bevel gear 12 is fixedly connected to the bottom of the connecting shaft 11, a bevel gear ring 13 meshing with the bevel gear 12 is fixedly connected to the outer wall of the sealing ring 7, and the two sealing rings 7 are fixedly connected by a first connecting rod 14;

[0033] First, when the enameled wire 5 enters the dryer 2 for drying and passes through the cooling box 3, and finally is wound by the winding disk 36, a hot air furnace or a heater or other heating components are provided inside the dryer 2, and a fan for enhancing the air flow inside the dryer 2 is also provided inside the dryer 2, and a fan or other cooling device for cooling the enameled wire 5 can be provided inside the cooling box 3;

[0034] Two expansion airbags 6 are provided, one expansion airbag 6 is initially expanded and closely attached to the outer wall of the enameled wire 5, and the other expansion airbag 6 is in a contracted state. When the enameled wire 5 is dried, the electric heating wire 16 located inside the piston sleeve 8 can be started to heat the air inside the piston sleeve 8 through the electric heating wire 16, and the heat can be gathered inside the sealed expansion airbag 6. The expansion airbag 6 is initially expanded and attached to the outer wall of the enameled wire 5, so that the heat inside the expansion airbag 6 can be conducted to the enameled wire 5, and the surface of the enameled wire 5 entering the drying machine 2 can be heated. The surface of the enameled wire 5 is preheated. The enameled wire 5 usually has a coating or paint layer. These coatings are very sensitive to temperature changes. If directly exposed to high temperature, thermal shock is likely to occur, causing the coating to crack or peel off. The expansion airbag 6 expands and fits on the outer wall of the enameled wire 5 to a certain extent to avoid the thermal shock effect of direct contact with high temperature, making the temperature change more gentle and reducing the risk of coating damage. In this way, the enameled wire 5 is prevented from directly entering the high-temperature drying machine 2 for drying, causing cracks, bubbling or shedding of the surface coating, thereby improving the molding effect of the enameled wire 5 after drying;

[0035] When the enameled wire 5 enters the drying machine 2 for drying, the driving motor 10 is started, and the output end of the driving motor 10 drives the connecting shaft 11 to drive the bevel gear 12 to rotate in a circle, and then drives the bevel gear ring 13 to drive the expansion airbag 6 to rotate in a circle through the sealing ring 7, so as to continuously adjust the contact position with the enameled wire, so that the heat distribution is more uniform, avoiding the problem of local overheating or overcooling, and avoiding the thermal shock that may be caused by direct heating. The surface coating of the enameled wire can be dried in a milder environment, avoiding the peeling or cracking of the coating due to excessive temperature difference, thereby further improving the drying effect of the enameled wire 5.

[0036] Example 2

[0037] A reciprocating suction device for inflating and sucking air inside the expansion airbag 6 is arranged on the inner side of the preheating tube 4. The reciprocating suction device includes a piston block 15 installed on the inner side of the piston sleeve 8. A sliding rod 19 is fixedly connected to the top of the piston block 15, and one end of the sliding rod 19 penetrates the outer wall of the piston sleeve 8 and is slidably connected to the piston sleeve 8. A connecting spring 20 is installed between the piston block 15 and the piston sleeve 8. A toggle assembly for toggling the sliding rod 19 for reciprocating movement is arranged between the outer wall of the connecting shaft 11 and the sliding rod 19. The reciprocating suction device also includes an auxiliary rod 2 fixedly connected between the two piston sleeves 8. 3. The inner side of the auxiliary rod 23 is rotatably connected with a rotating shaft 27, the outer wall of the rotating shaft 27 is fixedly connected with a spur gear 26, and the two sides of the spur gear 26 are respectively meshed with spur racks 24, one end of one spur rack 24 is fixedly connected with a third connecting rod 28, the outer wall of the other spur rack 24 is fixedly connected with a second connecting rod 25, the third connecting rod 28 and the second connecting rod 25 are respectively fixedly connected with a sliding rod 19, the toggle assembly includes a spherical rod 21 arranged on one side of the sliding rod 19, the outer wall of the connecting shaft 11 is fixedly connected with an inclined block 22, the top of the inclined block 22 is provided with an inclined surface, and the bottom of the spherical rod 21 is against the inclined surface;

[0038] When the connecting shaft 11 rotates in a circle, it drives the inclined block 22 to rotate in a circle. When the contact position between the top of the inclined block 22 and the spherical rod 21 rotates from the highest point to the lowest point, the pressure on the spherical rod 21 gradually decreases, so that the connecting spring 20 pushes the piston block 15 to move downward to push the hot air inside the piston sleeve 8 into the expansion airbag 6, so that the expansion airbag 6 gradually expands. When the contact position between the inclined block 22 and the spherical rod 21 rotates from the lowest point to the highest point, the spherical rod 21 is pushed to drive the piston block 15 to move upward to inhale the inside of the expansion airbag 6. The inclined block 22 rotates continuously, so that the piston block 15 moves continuously to form a reciprocating suction on the inside of the expansion airbag 6, thereby forming a reciprocating suction on the inside of the expansion airbag 6. The expansion bag 6 can be expanded and contracted reciprocatingly. The expansion and contraction help the hot air to be transferred to each part of the expansion bag 6 more evenly, so that the contact between the surface of the expansion bag 6 and the surface of the enameled wire is more even, avoiding local overheating or overcooling. The expansion and contraction of the expansion bag 6 ensures that it can always maintain appropriate contact pressure with the outer wall of the enameled wire 5, which helps to ensure that the transfer of heat and airflow is not hindered. The gas in the expansion bag 6 is constantly renewed through the process of suction and exhaust, which can prevent overheating or moisture accumulation, and ensure that the air inside the expansion bag 6 is always kept in a suitable state, thereby improving the drying efficiency, thereby further improving the effect of preheating the surface of the enameled wire 5;

[0039] When a sliding rod 19 pushes a piston block 15 to move downward to inflate an expansion airbag 6, a spur gear 26 is driven to rotate through a spur rack 24, thereby driving another spur rack 24 to drive another piston block 15 to move upward to inhale air into the other expansion airbag 6. This reciprocating process allows one expansion airbag 6 to expand while the other expansion airbag 6 contracts. The alternating expansion and contraction can ensure that heat is evenly distributed in the expansion airbag 6 and is transferred to the surface of the enameled wire through the contact between the expansion airbag 6 and the enameled wire 5. This uniform heat distribution helps to preheat the expansion airbag 6, allowing it to gradually adapt to the temperature entering the dryer 2, thereby avoiding coating problems caused by excessive temperature differences.

[0042] When it is necessary to adjust the expansion force of the expansion bag 6, the staff can manually rotate the first one-way threaded screw 30 to drive the movable block 32 to drive the spherical rod 21 to move upward, so as to adjust the height of the spherical rod 21, and then rotate the second one-way threaded screw 35 to drive the L-shaped seat 34 to drive the spherical rod 21 to move horizontally, so as to adjust the distance between the spherical rod 21 and the highest point of the top inclined surface of the inclined block 22, so as to adjust the distance that the spherical rod 21 is pushed, thereby realizing the control of the amount of gas inflated inside the expansion bag 6, so that the pressure applied by the expansion bag 6 to the enameled wire 5 during the expansion process is maintained in an appropriate range, avoiding over-expansion or under-expansion, thereby affecting the uniform drying of the coating, and at the same time, it can realize the preheating of enameled wires 5 of different thicknesses, thereby improving the overall practicality of the device;

[0043] When the spherical rod 21 is adjusted to above the designated position, the first one-way threaded screw 30 can be rotated in the reverse direction so that the spherical rod 21 can fit on the top inclined surface of the inclined block 22 .
