Description

Technical Field

[0001] This invention relates to the technical field of enameled wire winding devices, and in particular to anti-enameled wire winding equipment for enameled wire production and processing. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as the quality of raw materials, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] In the production and processing of transformer enameled wire, the processed transformer enameled wire needs to be wound onto the corresponding take-up spool, thereby facilitating the winding or unwinding operation of the transformer enameled wire.

[0004] A transformer enameled wire winding structure, such as "CN211971376U", includes: a winding assembly, a wire assembly, a first adjusting limit assembly, a second adjusting limit assembly, and a positioning and mounting assembly. The winding assembly includes a winding positioning post, the wire assembly includes an electromagnetic wire, the first adjusting limit assembly includes a first limiting plate, a first adjusting plate, a first elastic post, and a first adjusting bushing, the second adjusting limit assembly includes a second limiting plate, a second adjusting plate, a second elastic post, and a second adjusting bushing, and the positioning and mounting assembly includes a positioning ring and a positioning bushing. This transformer enameled wire winding structure, by setting up the winding assembly, wire assembly, first adjusting limit assembly, second adjusting limit assembly, and positioning and mounting assembly, can adjust the spatial position of the winding area, thereby adapting to the winding operation of electromagnetic wires of different specifications. Furthermore, the overall disassembly and installation operations are relatively convenient during collection or unwinding operations, thus improving production efficiency.

[0005] During the winding process after the enamel film has cured, the enamel layer on the surface of the enameled wire is prone to peeling off. If there is dust, the winding path is open, and there is no effective dust prevention and static electricity management around the guide and reel. Fine dust or metal shavings are easily adsorbed on the wire surface, and the overlapping of the wires will produce a sandpaper effect, causing continuous slight scratches and paint peeling. When the enamel layer is still warm and thermally softened, it enters the high-tension wire laying process, and the interlayer compression and contact with the flange edge make it more prone to peeling. Summary of the Invention

[0006] In view of the aforementioned existing problems, the present invention is proposed.

[0007] The purpose of this invention is to solve the problem of paint peeling off easily during the winding of enameled wire in the prior art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] On one hand, the present invention provides a winding device for preventing paint peeling in the production and processing of enameled wire, which includes a base, a winding frame, and a winding roller. The winding frame is disposed above the base, and the winding roller is rotatably disposed on the winding frame. The winding roller is driven to rotate by a main motor. A dust cover is provided above the base, and the winding frame is located inside the dust cover. A feeding groove is provided on one side of the dust cover. The outer wall of the dust cover at the feeding groove is connected to a drying mechanism and a water cooling mechanism respectively through an expanding mask. The water cooling mechanism includes a central tube and an outer tube. The central tube passes through the interior of the outer tube and is filled with cool liquid water. The drying mechanism includes a drying frame and a first fan. The output end of the central tube is connected to one end of the drying frame. The first fan is used to blow air into the interior of the drying frame. One end of the enameled wire passes through one end of the central tube, passes through the water cooling mechanism, the drying mechanism, and the expanding mask, and is wound onto the winding roller. A lubrication mechanism is provided on the feeding groove.

[0010] Furthermore, the central tube is located inside the outer tube, with an inlet pipe and an outlet pipe at each end. The inlet pipe and outlet pipe penetrate the side wall of the outer tube and are connected to the lower and upper ends of the central tube. The two ends of the central tube are connected to inclined pipes. The output end of the central tube is connected to the end face of the drying rack through the inclined pipe. The central tube is located at the lower end of the inclined pipe. The central tube extends to the upper end of the outer tube and is connected to a through pipe. A liquid level sensor is installed in the through pipe. By setting the two inclined pipes, the central tube is at its lowest point, controlling the inlet and outlet water volume of the cooling fluid in the central tube. The height of the cooling fluid surface is kept between the upper end of the central tube and the upper end of the inclined pipe as much as possible to avoid insufficient cooling fluid or overflow. Even if a small amount overflows, the end connected to the drying rack directly overflows into the drying rack and is discharged from the lower end of the drying rack. The water inlet at the lower end and the water outlet at the upper end of the central tube can completely submerge the enameled wire inside the central tube to cool it down and reduce the residual heat inside the enameled wire that may cause paint peeling during winding.

[0011] Furthermore, a fixed pipe is provided on the upper part of the inner wall of the drying rack, and the first fan is mounted on the base. The air outlet of the first fan is connected to the fixed pipe, and multiple blowers are connected below the fixed pipe. Multiple guide components are evenly provided on the inner walls of the drying rack, the inclined pipe, and the central pipe. By driving the first fan, pure airflow from the outside is introduced into the interior of the drying rack to quickly dry the enameled wire located inside the drying rack. At the same time, it can also be used to remove dust and powder from the interior of the drying rack and the surface of the enameled wire, preventing these particles from rubbing and causing paint peeling when the enameled wire is wound and rewound.

[0012] Furthermore, the lower interior of the drying rack is sloped, and the lower interior of the drying rack facing the outer tube is lower than the other end. A drainage groove is provided at the lower end of the drying rack, and multiple slots are provided at the lower end of the drying rack. A water receiving trough is provided at the bottom of the drying rack. One end of the water receiving trough is connected to the outer wall of the drying rack above the drainage groove via a baffle plate. Water droplets dripping from the surface of the enameled wire or a small amount of water overflowing from the central tube into the drying rack can be discharged from the drainage groove along the slope, and finally flow into the water receiving trough for temporary storage along the baffle plate, or drip directly down from the slots. An additional pipe can be provided to drain the water in the water receiving trough.

[0013] Furthermore, the guiding assembly includes side frames and several guide wheels. The side frames are provided in two sets and are respectively arranged on both sides of the inner wall of the drying rack body, the inclined tube, and the central tube. The guide wheels are rotatably mounted on the side frames. The guide wheels on the two side frames are symmetrically arranged. The guide wheels are arranged with a structure that is wide at both ends and narrow in the center. The center positions of the symmetrically arranged guide wheels are used to pass through the enameled wire. The end faces of adjacent guide wheels on the same side are linked by belts. The guide wheels located on the drying rack body are driven to rotate by a first motor. The first motor is mounted on the drying rack body. By driving the first motor, the guide wheels located on the two side frames are driven to rotate synchronously, which is used to transport the enameled wire through the water cooling mechanism, the inclined tube, and the drying mechanism.

[0014] Furthermore, an upper wheel and a lower wheel are rotatably arranged at the top and bottom of the feed trough, respectively. Sliders are symmetrically arranged at both ends of the lower wheel. Fixed frames are provided at both ends of the feed trough. The sliders are slidably disposed within the fixed frames. The lower part of the fixed frames is connected to the sliders via a first spring. A push shaft is provided above the sliders. The upper end of the push shaft passes through the fixed frames and the dust cover and extends upwards. When feeding enameled wire, one end of the enameled wire is placed between two guide wheels inside the inclined tube at the end face. Through the rotation of the guide wheels, the enameled wire is threaded sequentially through the tube. After passing through the water cooling mechanism, inclined tube, and air drying mechanism, the enameled wire end face is guided through the dust cover as the guide wheel continues to rotate. At this time, by pressing the push shaft, the lower wheel is moved down to the bottom. At this time, the top of the lower wheel is flush with the bottom of the inside of the dust cover, and the end of the enameled wire can pass smoothly between the upper and lower wheels and enter the dust cover. After the worker fixes the end of the enameled wire on the take-up roller, the take-up operation can be carried out. After the material is loaded, the push shaft is released, and under the action of the first spring, the lower wheel is pushed up to the highest point. At this time, the upper and lower wheels provide basic limit for the enameled wire.

[0015] Furthermore, the lubrication mechanism includes a lubricant storage tank, a stirring shaft, and a connecting pipe. The lubricant storage tank is positioned above the dust cover. The stirring shaft is rotatably mounted inside the lubricant storage tank. A second motor is located above the lubricant storage tank, driving the stirring shaft to rotate. The output end of the lubricant storage tank is rotatably and sealed to the end face of the upper wheel via the connecting pipe. Felt pads are provided on the outer walls of both the upper and lower wheels. The upper wheel has a hollow structure, and multiple discharge holes are evenly distributed on its side wall. A pressing outlet is provided within each discharge hole. The material handling mechanism consists of a lubricant storage tank containing wax emulsion. Under gravity, the wax emulsion flows into the upper wheel through a connecting pipe, filling the upper wheel completely. A pressing discharge mechanism in the discharge port prevents the liquid inside the upper wheel from overflowing. When an enameled wire passes by the pressing discharge mechanism, it is squeezed inward, causing a small amount of wax emulsion to flow out of the upper wheel. Excess wax emulsion is scraped off by a felt pad, forming a thin film. This film drives the second motor to rotate the stirring shaft, preventing the wax emulsion inside the lubricant storage tank from separating. The wax emulsion inside the upper wheel is mixed as the upper wheel rotates continuously.

[0016] Furthermore, the feed trough is in contact with the surface of the lower wheel below, and a liquid outlet trough communicating with the feed trough is provided on the dust cover located below the lower wheel. The liquid outlet trough is connected to the outside. The liquid outlet trough is provided to discharge excess emulsion and prevent it from overflowing into the mask or the dust cover.

[0017] Furthermore, the pressing and discharging mechanism includes a pressing shaft, a mounting block, and an end cap. The mounting block is disposed inside the upper wheel. The pressing shaft is a hollow structure, with one end passing through the mounting block and the liquid outlet groove from the inside of the upper wheel and having a flexible strip. The flexible strip has a through groove communicating with the pressing shaft. The pressing shaft has an end cap at its inner end, and the inner side of the end cap is slidably sealed to the outer side of the mounting block. The pressing shaft has a liquid inlet hole on its inner sidewall. The end cap is assembled and connected to the upper wheel via a second spring. In the initial state, the second spring pulls the end cap to seal with the mounting block, and the pressing shaft moves downward. Its liquid inlet hole is inside the mounting block, and liquid cannot pass through the pressing shaft to be discharged outward. When the enameled wire squeezes the pressing shaft or the nearby flexible strip from the outside, the pressing shaft moves inward, causing the end cap to separate from the mounting block. The liquid inlet hole is exposed, and the liquid inside the upper wheel passes through the liquid inlet hole and is discharged from the pressing shaft, adhering to the surface of the enameled wire.

[0018] Furthermore, a second fan is provided above the dust cover, and the port of the second fan is connected to the inside of the dust cover. An electrostatic dust removal pipe is provided on the base inside the dust cover. An inspection door is provided on the side of the dust cover. The second fan is used to remove dust adhering to the winding roller and winding frame. In addition, it can also accelerate the film formation of wax emulsion on the surface of the enameled wire. When loading, unloading, or repairing the winding roller of the enameled wire, the inspection door can be opened for operation. The inspection door is closed during use to achieve the effect of dust prevention during the winding process.

[0019] The beneficial effects of this invention are:

[0020] 1. The connection between the central tube and the drying rack in this invention completes cooling, dust removal, and drying before winding, which can prevent the enameled wire from being rubbed off by dust particles during the moving and winding process. The micro-lubrication and clean airflow management in the dust cover stabilizes the state of the wire entering the winding area within a controllable window, thereby reducing friction. The synchronous conveying of the guide wheel and the convenient feeding structure further reduce the impact and accidental scratches during threading and start-stop processes.

[0021] 2. The present invention drives a first fan to introduce a clean airflow from the outside into the drying rack body to quickly dry the enameled wire located inside the drying rack body. At the same time, it can also be used to remove dust and powder from the inside of the drying rack body and the surface of the enameled wire, so as to avoid the paint peeling caused by friction of these particles when the enameled wire is wound and rolled up.

[0022] 3. In this invention, the lubrication mechanism stores the wax emulsion in a closed manner and extrudes it through the pressing and discharging mechanism of the hollow upper wheel. The wax emulsion is then coated into an extremely thin dry film by the felt pad. This reduces the friction coefficient at the guide and cable routing points and avoids the risk of aerosols and dust from spraying. In addition, the stirring in the upper wheel and storage tank prevents stratification, and the liquid outlet tank collects excess emulsion. The coating is clean and controllable and does not contaminate the winding area. Attached Figure Description

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, as used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0040] Please see Figures 1-11This invention provides a technical solution: a rewinding device for preventing paint peeling in enameled wire production, comprising a base 1, a rewinding frame 2, and a rewinding roller 3. The rewinding frame 2 is disposed above the base 1, and the rewinding roller 3 is rotatably disposed on the rewinding frame 2. The rewinding roller 3 is driven to rotate by a main motor 4. A dust cover 5 is provided above the base 1, and the rewinding frame 2 is located inside the dust cover 5. A feeding groove 6 is provided on one side of the dust cover 5. The outer wall of the dust cover 5 at the feeding groove 6 is connected to a drying mechanism and a water cooling mechanism respectively through an expanding mask 7. The water cooling mechanism includes a middle... The inner tube 811 and outer tube 812 are connected. The inner tube 811 passes through the inner tube 812 and is filled with cold liquid water. The air drying mechanism includes an air drying frame 911 and a first fan 912. The output end of the inner tube 811 is connected to one end of the air drying frame 911. The first fan 912 is used to blow air into the air drying frame 911. One end of the enameled wire passes through one end of the inner tube 811, passes through the water cooling mechanism, the air drying mechanism and the expanding mask 7, and is wound on the take-up roller 3. The feed trough 6 is equipped with a lubrication mechanism.

[0041] The central tube 811 is located inside the outer tube 812 and has an inlet pipe 821 and an outlet pipe 822 at its two ends respectively. The inlet pipe 821 and the outlet pipe 822 pass through the side wall of the outer tube 812 and are connected to the lower and upper ends of the central tube 811. The two ends of the central tube 811 are connected to inclined pipes 823 respectively. The output end of the central tube 811 is connected to the end face of the drying rack 911 through the inclined pipes 823. The central tube 811 is located at the lower end of the inclined pipes 823. The central tube 811 extends to the upper end of the outer tube 812 and is connected to a through pipe 825. A liquid level sensor 824 is installed in the through pipe 825.

[0042] By setting two inclined tubes 823, the central tube 811 is positioned at its lowest point. The inlet and outlet water volume of the cooling fluid in the central tube 811 is controlled, and the height of the cooling fluid surface is kept between the top of the central tube 811 and the top of the inclined tube 823 as much as possible. This avoids insufficient cooling fluid or overflow. Even if a small amount overflows, the end connected to the drying rack 911 will directly overflow into the drying rack 911 and be discharged from the bottom of the drying rack 911. The water entering from the bottom and exiting from the top of the central tube 811 can completely submerge the enameled wire inside the central tube 811, cooling it and reducing residual heat inside the enameled wire that could cause paint peeling during winding.

[0043] It should be noted that the liquid level sensor 824 is a common existing technology, and its structure will not be described in detail here. The liquid level sensor 824 can be a hydrostatic liquid level transmitter. The working principle is to insert a thin insulating probe into the pipe, with a ring of small stainless steel electrodes exposed at the lowest and highest positions. A common electrode is made at the bottom or on the pipe wall. The controller applies a small alternating current to the electrodes. When the liquid rises to a certain electrode, that electrode becomes conductive with the common electrode through the liquid. The controller immediately identifies the conduction or disconnection as "too high" or "too low". Thus, a single probe simultaneously provides two signals, one for high level and one for low level. With a wave-damping sleeve with small holes, the reading is more stable. When the liquid level sensor 824 detects that the liquid level in the central tube 811 is clearly lower than the lowest point or higher than the highest point, water needs to be added or drained from the central tube 811 accordingly to ensure that the liquid level is between the highest and lowest points.

[0044] A fixed pipe 921 is provided on the upper part of the inner wall of the drying rack 911. A first fan 912 is installed on the base 1. The air outlet of the first fan 912 is connected to the fixed pipe 921. Multiple blowers 922 are connected below the fixed pipe 921. Multiple guide components are evenly provided on the inner walls of the drying rack 911, the inclined pipe 823 and the central pipe 811.

[0045] By driving the first fan 912, clean airflow from the outside is introduced into the drying rack 911 to quickly dry the enameled wire inside the drying rack 911. At the same time, the drying process can also remove dust and powder from inside the drying rack 911 and the surface of the enameled wire, preventing these particles from rubbing against each other and causing paint peeling when the enameled wire is wound and rewound.

[0046] The lower interior of the drying rack 911 is sloped. The lower interior of the drying rack 911 facing the outer tube 812 is lower than the other end. A drainage groove 931 is provided at the lower interior of the drying rack 911. Multiple drainage grooves 932 are provided at the lower end of the drying rack 911. A water receiving groove 933 is provided at the bottom of the drying rack 911. One end of the water receiving groove 933 is connected to the outer wall of the drying rack 911 above the drainage groove 931 via a baffle plate 934.

[0047] Water droplets dripping from the surface of the enameled wire or a small amount of water overflowing from the central tube 811 into the drying rack 911 can be discharged from the drainage groove 931 along the slope, and finally flow into the water receiving groove 933 along the water baffle 934 for temporary storage, or drip directly down from the drain 932. An additional pipe can be installed to drain the water in the water receiving groove 933.

[0048] The guiding assembly includes a side frame 101 and several guide wheels 102. The side frame 101 has two sets and is respectively set on both sides of the inner wall of the drying rack body 911, the inclined tube 823 and the central tube 811. The guide wheels 102 are rotatably mounted on the side frame 101. The guide wheels 102 on the two side frames 101 are symmetrically arranged. The guide wheels 102 have a structure that is wide at both ends and narrow in the center. The center position of the symmetrically arranged guide wheels 102 is used to pass through the enameled wire. The end faces of adjacent guide wheels 102 on the same side are linked by belts. The guide wheel 102 located at the drying rack body 911 is driven to rotate by a first motor 103. The first motor 103 is set on the drying rack body 911.

[0049] By driving the first motor 103, the guide wheels 102 located on the two side frames 101 are driven to rotate synchronously, which is used to transport the enameled wire through the water cooling mechanism, the inclined tube 823 and the air drying mechanism.

[0050] It should be noted that only one belt is used to link the end faces of two adjacent guide wheels 102, and the inner side of the belt meshes with the end face of the guide wheel 102, so there will be no slippage. In addition, the side frames 101 on both sides are equipped with a first motor 103 to ensure that all guide wheels 102 can operate smoothly.

[0051] The upper wheel 111 and the lower wheel 112 are respectively rotatably arranged at the top and bottom of the feed trough 6. The lower wheel 112 has sliders 113 symmetrically arranged at both ends. The feed trough 6 has fixed frames 114 at both ends. The sliders 113 are slidably arranged in the fixed frames 114. The lower part of the fixed frame 114 is connected to the sliders 113 by a first spring 115. The upper part of the sliders 113 is provided with a push shaft 116. The upper end of the push shaft 116 passes through the fixed frame 114 and the dust cover 5 and extends to the top.

[0052] When feeding the enameled wire, one end of the enameled wire is placed between the two guide wheels 102 inside the inclined tube 823. Through the rotation of the guide wheels 102, the enameled wire passes through the water cooling mechanism, the inclined tube 823 and the air drying mechanism in sequence. As the guide wheels 102 continue to rotate, the end face of the enameled wire is guided and passes through the expanding mask 7. At this time, by pressing the push shaft 116, the lower wheel 112 is driven to move down to the bottom. At this time, the top of the lower wheel 112 is flush with the bottom of the inside of the expanding mask 7. The end of the enameled wire can pass smoothly between the upper wheel 111 and the lower wheel 112 and enter the dust cover 5. After the worker fixes the end of the enameled wire on the winding roller 3, the winding operation can be carried out. After the feeding is completed, the push shaft 116 is released. Under the action of the first spring 115, the lower wheel 112 is pushed up to the highest point. At this time, the upper wheel 111 and the lower wheel 112 provide basic limit for the enameled wire.

[0053] The lubrication mechanism includes a lubricating fluid storage tank 121, a stirring shaft 122, and a connecting pipe 123. The lubricating fluid storage tank 121 is located above the dust cover 5. The stirring shaft 122 is rotatably installed inside the lubricating fluid storage tank 121. A second motor 124 is provided above the lubricating fluid storage tank 121. The stirring shaft 122 is driven to rotate by the second motor 124. The output end of the lubricating fluid storage tank 121 is sealed and rotatably connected to the end face of the upper wheel 111 through the connecting pipe 123. Felt pads 125 are provided on the outer walls of both the upper wheel 111 and the lower wheel 112. The upper wheel 111 has a hollow structure. Multiple discharge holes 126 are evenly opened on the side wall of the upper wheel 111. A pressing discharge mechanism is provided in the discharge holes 126.

[0054] The lubricant storage tank 121 stores wax emulsion, which flows into the upper wheel 111 through the connecting pipe 123 under the action of gravity, so that the wax emulsion fills the upper wheel 111. The setting of the pressing discharge mechanism in the discharge hole 126 prevents the liquid inside the upper wheel 111 from overflowing. When an enameled wire passes by the pressing discharge mechanism, it is squeezed inward, and the wax emulsion inside the upper wheel 111 flows out slightly. The excess wax emulsion is scraped off by the felt pad 125 to form a film. The second motor 124 drives the stirring shaft 122 to rotate, which prevents the wax emulsion inside the lubricant storage tank 121 from separating. The wax emulsion inside the upper wheel 111 is mixed as the upper wheel 111 rotates continuously.

[0055] Among them, wax emulsion is an aqueous multiphase system formed by emulsification and dispersion of natural or synthetic wax. It is mainly used as an additive for coating materials. By adjusting the melting point of the wax, different properties can be given to the material. After it is applied to the wire, the water evaporates, the wax particles soften and reform into a film, leaving a thin solid wax film that plays a role in dry lubrication.

[0056] The feed trough 6 is in contact with the surface of the lower wheel 112. The dust cover 5 located below the lower wheel 112 is provided with a liquid outlet trough 13 that communicates with the feed trough 6. The liquid outlet trough 13 is connected to the outside.

[0057] The liquid outlet 13 is designed to drain excess emulsion and prevent it from overflowing into the mask 7 or dust cover 5.

[0058] The pressing and discharging mechanism includes a pressing shaft 141, a mounting block 142, and an end cap 146. The mounting block 142 is located inside the upper wheel 111. The pressing shaft 141 is a hollow structure, and one end passes through the mounting block 142 and the liquid outlet groove 13 from the inside of the upper wheel 111 and is provided with a flexible strip 144. The flexible strip 144 is provided with a through groove 145 that communicates with the pressing shaft 141. The pressing shaft 141 is provided with an end cap 146 at its inner end. The inner side of the end cap 146 is slidably sealed to the outer side of the mounting block 142. The pressing shaft 141 is provided with a liquid inlet hole 147 on its inner side wall. The end cap 146 is assembled and connected to the upper wheel 111 by a second spring 148.

[0059] In the initial state, the second spring 148 pulls the end cap 146 to seal the connection with the mounting block 142, and the pressing shaft 141 moves down. Its liquid inlet 147 is inside the mounting block 142, and the liquid cannot pass through the pressing shaft 141 to be discharged outward. When the enameled wire squeezes the pressing shaft 141 or the nearby soft strip 144 from the outside, the pressing shaft 141 moves inward, causing the end cap 146 to separate from the mounting block 142. The liquid inlet 147 is exposed to the outside, and the liquid inside the upper wheel 111 passes through the liquid inlet 147 and is discharged from the pressing shaft 141, adhering to the surface of the enameled wire.

[0060] A second fan 151 is provided above the dust cover 5. The port of the second fan 151 is connected to the inside of the dust cover 5. An electrostatic dust removal tube 152 is provided on the base 1 inside the dust cover 5. An inspection door 153 is provided on the side of the dust cover 5.

[0061] The second fan 151 is used to remove dust adhering to the winding roller 3 and winding frame 2. In addition, it can accelerate the film formation of wax emulsion on the surface of the enameled wire. When loading or unloading the enameled wire or when repairing the winding roller 3, the operation can be carried out by opening the maintenance door 153. During use, the maintenance door 153 is closed to achieve the effect of dust prevention during the winding process.

[0062] Working principle: Before feeding the enameled wire, the first fan 912 and the second fan 151 are turned on in advance to remove dust from the inside of the dust cover 5 and the drying rack 911. Then, one end of the enameled wire is placed between the two guide wheels 102 inside the inclined tube 823. Through the rotation of the guide wheels 102, the enameled wire passes through the water cooling mechanism, the inclined tube 823 and the drying mechanism in sequence, which further cools the enameled wire with water and cleans the dust on its surface. Then it is dried. As the guide wheels 102 continue to rotate, the end face of the enameled wire is guided and passes through the expanding mask 7. At this time, by pressing the push shaft 116, the lower wheel 112 is moved down to the bottom. At this time, the top of the lower wheel 112 is flush with the bottom of the inside of the expanding mask 7. The end of the enameled wire can pass smoothly between the upper wheel 111 and the lower wheel 112 and enter the dust cover 5. After the operator fixes the end of the enameled wire on the winding roller 3, the winding operation can be performed. After the feeding is completed, the push shaft 116 is released. Under the action of the first spring 115, the lower wheel 112 is pushed up to the highest point. At this time, the upper wheel 111 and the lower wheel 112 provide basic positioning for the enameled wire. The lubricant storage tank 121 contains wax emulsion. Under the action of gravity, it flows into the upper wheel 111 through the connecting pipe 123, so that the wax emulsion fills the upper wheel 111. The setting of the pressing discharge mechanism in the discharge hole 126 prevents the liquid inside the upper wheel 111 from overflowing. When the enameled wire passes through the pressing discharge mechanism, it is squeezed inward. The wax emulsion inside the upper wheel 111 flows out slightly and the excess wax emulsion is scraped off by the felt pad 125 to form a film for protecting the enameled wire. The friction is reduced, and the effect of not easily peeling off the paint is achieved. Finally, it enters the dust cover 5 and is wound on the winding roller 3. The main motor 4 drives the winding roller 3 to rotate, so that the enameled wire is wound regularly on the winding roller 3.
