Abstract

This invention discloses a wig fiber curling, styling, and drying production line, comprising a dual-station switching winding device, a belt conveyor heat setting device, and two vertically connected series drying boxes arranged from left to right. The invention first winds the fiber bundles onto anti-slip curling and styling tubes, then places the anti-slip curling and styling tubes into the assembly line-style belt conveyor heat setting device for hot steam styling. Finally, several anti-slip curling and styling tubes are connected in series and placed into the vertically connected series drying box for batch drying. After drying, the fiber bundles are removed from the anti-slip curling and styling tubes to form curled wig bundles. The drying process employs negative pressure extraction + positive pressure air supply, with high-temperature air drying the wig bundles from the inside out of the anti-slip curling and styling tubes. This results in faster and more uniform drying of the wig bundles, controllable temperature and humidity, and prevents the wig bundles from tangling together when removed after drying.

Description

Technical Field

[0001] This invention belongs to the field of wig manufacturing technology, specifically relating to a wig fiber curling, shaping, and drying production line. Background Technology

[0002] Among wig (hair fiber) products, curly wigs are one of the most common types. Curly wigs are typically made by winding hair strands around an anti-slip curling and setting tube, then placing the tube inside a setting machine where it is heat-steamed to achieve its desired shape. Currently, the production process for curly wigs usually involves first winding the hair fibers around the outer circumference of the anti-slip curling and setting tube, then placing the tube inside the setting machine for heat setting, and finally placing it in a drying oven for drying. This production process relies heavily on manual labor, resulting in high labor intensity and low production efficiency. Especially during the heat setting and drying processes, the styling cabinets are relatively small, and the anti-slip curling tubes placed inside are often piled up, resulting in uneven styling effects and inconsistent quality within the same batch of products. Since the existing anti-slip curling tubes are made of high-temperature resistant plastic tubing, the wigs in contact with the outer circumference of the plastic tube cannot dry thoroughly without removing the wig strands for drying. Therefore, currently, the curled wigs are usually removed from the anti-slip curling tubes after styling, and then placed in the drying oven for drying. This process is cumbersome, and many wig strands are piled up in the drying oven, resulting in low drying efficiency and poor results. Furthermore, when removing the wigs after drying, the strands easily become tangled together, making separation difficult. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention provides a wig fiber curling, shaping and drying production line that is simple to operate, highly efficient, produces good and consistent quality, and prevents wig strands from crossing and tangling.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wig fiber curling, shaping and drying production line, including a dual-station switching winding device, a belt conveyor heat shaping device and two shaping tubes vertically connected in series drying boxes arranged from left to right; The dual-station switching winding device includes a winding bracket, on which a station switching motor with a vertically upward main shaft is mounted. The main shaft of the station switching motor is coaxially connected to a switching shaft via a coupling. The switching shaft is rotatably connected to the winding bracket via a pressure bearing. A horizontally positioned station switching disk is coaxially fixed to the upper end of the switching shaft. A winding rotation positioning component is provided on the left and right sides of the station switching disk. The two winding rotation positioning components have the same structure and are symmetrical about the center of the switching shaft.

[0005] The winding rotary positioning assembly includes a hollow shaft motor and a pneumatic internal expansion clamp. The hollow shaft motor is fixed on the workstation switching plate, and the hollow shaft of the hollow shaft motor is perpendicular to the workstation switching plate. The upper end of the hollow shaft of the hollow shaft motor is connected to the lower air port of the pneumatic internal expansion clamp. The pneumatic internal expansion clamp is fitted with an anti-slip winding and shaping tube, and the lower end of the hollow shaft of the hollow shaft motor is connected to a high-pressure air supply pipe that passes through the workstation switching plate.

[0006] The anti-slip curling shaping tube includes a vertically arranged tube body with several internal and external air holes. The outer circumference of the tube body has spiral anti-slip ridges. The upper and lower ends of the tube body are respectively equipped with an upper limit ring and a lower limit ring with an outer diameter larger than the tube body. The inner diameters of the upper and lower limit rings are equal to the inner diameter of the tube body. The upper end face of the upper limit ring has an inner tube connector with an outer tube connector of equal length to the inner tube connector. The inner diameter of the outer tube connector is equal to the outer diameter of the inner tube connector. An annular groove is formed on the inner circumference of the outer tube connector near the lower limit ring. A sealing ring is located within the annular groove, its upper end face contacting the lower end face of the lower limit ring. The inner diameter of the sealing ring is equal to the inner diameter of the lower limit ring. The inner circumference of the outer tube connector is fitted onto a pneumatic internal expansion clamp, which expands radially and presses against the inner circumference of the outer tube connector.

[0007] The tube body, anti-slip ridge strips, upper limit ring, lower limit ring, outer tube connector and inner tube connector are made of one piece; the vent hole is a long hole structure, and the length of the vent hole is parallel to the center line of the tube body.

[0008] The belt conveyor heat setting device includes a conveyor support, on which a setting box is mounted. The setting box is positioned along the left-right direction along its length. A drive pulley and a driven pulley are respectively located on the left and right sides of the outside of the setting box. An inlet and an outlet are respectively located on the left and right sides of the setting box. An automatic inlet gate is located at the inlet, and an automatic outlet gate is located at the outlet. The drive pulley and the driven pulley are connected by a ring-shaped conveyor belt. The upper half of the conveyor belt passes horizontally through the lower part of the inlet and outlet. The lower half of the conveyor belt is located below the setting box. Guide rollers for supporting the upper half of the conveyor belt are provided inside the setting box. A convex positioning post is evenly provided on the conveyor belt. The lower outer circle of the positioning post has the same diameter as the inner circle of the outer sleeve joint. The upper outer circle diameter of the positioning post is smaller than the inner diameter of the tube. The outer sleeve joint at the lower end of the anti-slip and curling setting tube is fitted onto the positioning post. A vertical guide rail is provided on the upper part of the left and right inner walls of the shaping box. A steam supply pipe is horizontally arranged between the two vertical guide rails. The left and right ends of the steam supply pipe are fixedly connected to the sealing sliders that are slidably arranged on the adjacent vertical guide rails. The upper middle part of the steam supply pipe is connected to the main air supply pipe that extends upward into the shaping box. The upper left and right sides of the steam supply pipe are respectively connected to the lifting cylinders for driving the steam supply pipe to move up and down. The lower part of the steam supply pipe is provided with several short air supply tubes at intervals. The number of short air supply tubes is the same as the number of positioning columns that move into the shaping box and they correspond one-to-one.

[0009] The vertical series drying oven for shaping tubes includes a box body with support legs at the bottom and a door at the front. A high-temperature air blowing mechanism is located in the lower part of the box body. A mounting plate is horizontally positioned above the high-temperature air blowing mechanism within the box body. Several ventilation pipes, all open from top to bottom, are evenly distributed on the mounting plate. The upper ends of the ventilation pipes protrude from the surface of the mounting plate. Each ventilation pipe is detachably connected to a vertical series assembly for preventing slippage and curling of the shaping tubes. A positioning and anti-tipping device is located in the upper part of the box body, which is inserted into the upper end of all the vertical series assemblies for preventing slippage and curling of the shaping tubes. Several upper ventilation holes are opened on the top plate of the box body. A concentrating hood, smaller at the top and larger at the bottom, is located above the top plate of the box body, and an exhaust fan is connected to the upper end of the concentrating hood.

[0010] Two vertically connected drying boxes with shaping tubes are symmetrically arranged about the length of the conveyor belt. The vertically connected anti-slip shaping tube assembly on the rear side includes several anti-slip shaping tubes inserted one after the other. The outer sleeve joint of the lower end of the bottom anti-slip shaping tube is fitted onto the vent pipe. The upper end of the vent pipe is pressed into the sealing ring inside the outer sleeve joint of the bottom anti-slip shaping tube. The inner tube joint of the upper end of the lower tube of two adjacent anti-slip shaping tubes is inserted into the outer sleeve joint of the lower tube. At the same time, the upper end of the inner tube joint of the lower tube is pressed into the sealing ring inside the outer sleeve joint of the upper tube.

[0011] The high-temperature air blowing mechanism includes a partition horizontally set below the mounting plate, a support plate closely attached to the inner wall of the box between the partition and the mounting plate, a ventilation hole in the center of the partition, several external ventilation holes evenly opened on the side panels and the box door below the partition, an electric heating tube inside the box below the partition, and several lower ventilation holes evenly opened on the partition.

[0012] A cylindrical plate located outside the ventilation holes is provided between the bottom plate and the partition of the box body. The electric heating tube is located in the cavity outside the cylindrical plate. Several internal ventilation holes are provided on the cylindrical plate. A drying motor is fixed at the bottom of the bottom plate of the box body. The main shaft of the drying motor extends vertically through the bottom plate into the cylindrical plate. Fan blades located inside the cylindrical plate are installed on the main shaft of the drying motor.

[0013] The enclosure contains a temperature sensor and a humidity sensor. The temperature sensor is located on the lower surface of the mounting plate, and the humidity sensor is located on the lower surface of the top plate of the enclosure. The positioning and anti-tipping device includes a horizontal beam arranged in the left-right direction. The left and right ends of the beam are fixedly connected to the inner walls of the left and right sides of the box, respectively. Several insertion holes are opened on the beam, which correspond one-to-one with the upper and lower parts of the vent pipe. A positioning rod is inserted into each insertion hole. The upper end of the positioning rod is equipped with a handle, and the lower end of the positioning rod extends into the inner tube connector at the uppermost anti-slip curling shaping tube.

[0014] Using the above technical solution, when the present invention is in operation, firstly, anti-slip curling and shaping tubes are fitted onto the pneumatic internal expansion clamps on both sides of the dual-station switching winding device. The inner circle of the outer sleeve joint at the lower end of the anti-slip curling and shaping tube is fitted onto the pneumatic internal expansion clamp. The pneumatic internal expansion clamp is activated, and the pneumatic internal expansion clamp expands radially to press the outer sleeve joint, thereby vertically positioning the anti-slip curling and shaping tube. Then, the hollow shaft motor of the winding rotation positioning component on the left working position is activated to drive the anti-slip curling and shaping tube to rotate, gradually winding the fiber bundle onto the anti-slip curling and shaping tube from bottom to top. When the fiber bundle on the left anti-slip curling and shaping tube is fully wound, the fiber bundle is cut. The station switching motor drives the station switching disk to rotate 180°, and the winding rotation positioning component on the right rotates to the working position. The winding and rotating positioning assembly, fully wrapped with fiber bundles, moves to the tube-changing position on the right. Then, the hollow shaft motor at the working position starts, driving the anti-slip curling and shaping tube to rotate, gradually winding the fiber bundles onto the tube from bottom to top. Simultaneously, the pneumatic internal expansion clamp at the tube-changing position on the right retracts radially, removing the fiber-bundled anti-slip curling and shaping tube from the clamp and placing it on a positioning post at the top left side of the belt conveyor of the belt-type heat-setting device. Then, a new anti-slip curling and shaping tube is fitted onto the pneumatic internal expansion clamp at the tube-changing position, and the clamp expands radially, fixing the anti-slip curling and shaping tube to the clamp as a single unit. After the anti-slip curling and shaping tube at the working position is fully wrapped with fiber bundles again, the process repeats as described above. In a circular operation, each time the anti-slip curled shaping tube wrapped with fiber bundles is removed from the tube changing position and placed in front of a positioning post at the top left side of the belt conveyor of the belt-type heat setting device, the drive pulley of the belt-type heat setting device, driven by a stepper motor, moves the upper half of the conveyor belt a certain distance to the right (this distance is equal to the distance between two adjacent positioning posts). When the anti-slip curled shaping tube wrapped with fiber bundles enters the setting box to the right, the automatic tube inlet door opens. After moving to the right and entering the setting box, the automatic tube inlet door closes, and the lifting cylinder extends to drive the steam supply pipe to move downward along the vertical guide rail. The short section of the steam supply pipe at the bottom is inserted into the upper port of the inner tube connector at the upper end of the anti-slip curled shaping tube. High-temperature steam flows through the main steam supply pipe, the steam supply pipe, and the short section of the steam supply pipe. Steam is introduced into the body of the anti-slip curling and shaping tube through the air supply tube. The steam is then directed outward through the air passage on the tube body to heat-shape the hair strands wrapped around the outer circumference of the tube. Before each start of the stepper motor, the lifting cylinder retracts upward, causing the lower end of the short air supply tube to disengage from the upper port of the inner tube connector. After each displacement of the conveyor belt, the lifting cylinder extends downward, causing the lower end of the short air supply tube to insert into the upper port of the inner tube connector. Once all the anti-slip curling and shaping tubes are inserted into the positioning posts in the shaping box, the automatic tube exit door opens before each start of the stepper motor. The rightmost heat-shaped anti-slip curling and shaping tube moves to the right out of the shaping box. The heat-shaped anti-slip curling and shaping tube is then removed from the positioning post and placed in one of the vertical series drying boxes for shaping tubes.Following the winding and heat-setting process described above, place the heat-set anti-slip curling tubes one by one into the vertically connected drying box for the styling tubes. Once the box is full, close the door and start the drying box to dry the hair strands wrapped in the heat-set anti-slip curling tubes. During the drying process, place the heat-set anti-slip curling tubes into a second vertically connected drying box. When the second box is almost full (with 3-5 more anti-slip curling tubes remaining), close the first vertically connected drying box. The drying oven is set up by opening the door and taking out the dried anti-slip curled styling tubes one by one from the vertically connected drying oven. After that, the second vertically connected drying oven is also almost full of anti-slip curled styling tubes. The door of the second vertically connected drying oven is closed, and the second drying oven is started to dry the wig bundles wound with the heat-set anti-slip curled styling tubes. During the drying process, the heat-set anti-slip curled styling tubes are placed back into the first vertically connected drying oven. This continuous cycle ensures that the winding, heat-setting, and drying operations are carried out without interruption, greatly improving production efficiency.

[0015] The specific process for placing anti-slip curled shaping tubes into the vertically connected drying oven is as follows: First, open the oven door. Then, install multiple anti-slip curled shaping tubes sequentially from bottom to top on the last or front (inner) row of ventilation pipes. Next, insert a positioning rod through the insertion hole on the crossbeam into the inner insertion tube connector at the top of the uppermost anti-slip curled shaping tube. This positions a set of anti-slip curled shaping tube vertically connected components to prevent them from tipping over. Following this installation method, install a set of anti-slip curled shaping tube vertically connected components on each of the remaining ventilation pipes and insert positioning rods for positioning.

[0016] The specific process of drying the fiber bundles wound on the anti-slip curled styling tubes in the vertical series drying oven is as follows: Close the oven door, start the exhaust fan, and turn on the electric heating tube. The exhaust fan creates negative pressure inside the oven, and external air enters the cavity below the partition through the external vent. The electric heating tube heats the incoming cold air. The heated high-temperature air then enters the series anti-slip curled styling tubes through the lower and upper vents on the partition and the ventilation pipe, and then enters the oven through the air passage on the tube. As the high-temperature air passes through the air passage, it dries the inside of the wig bundles wound on the outer circumference of the tube. The combined effect of the high-temperature air inside and outside the anti-slip curled styling tube greatly improves the drying efficiency of the wig bundles, ensuring that the inside of the wig bundles is also completely dried. Finally, the airflow enters the air-gathering hood through the upper vent on the top plate and is then drawn upwards by the exhaust fan.

[0017] The dual-station switching winding device uses a horizontal rotation switching method, allowing for tube changing operations at the switching position while winding is being performed at the working position. This improves the efficiency of fiber bundle winding. A pneumatic internal expansion clamp is used to position and hold the anti-slip, curled, and shaped tube, which is convenient, quick, reduces manual labor intensity, and improves work efficiency. The hollow shaft of the hollow shaft motor directly serves as the air supply path for the pneumatic internal expansion clamp, resulting in a simple and compact structure. As the fiber bundle is wound onto the tube, the anti-slip ridges effectively position the fiber bundle, preventing it from sliding down the tube.

[0018] The belt conveyor heat setting device operates in an assembly line fashion. Timing begins when the anti-slip curling tube enters the setting box and continues until it exits. The tube moves from left to right within the box using a stepping motion, achieving automated operation. During heat setting, hot steam enters from inside the tube and exits through vents, heat-setting the fiber bundles wound around its outer circumference. This airflow ensures consistent setting throughout the fiber bundles, guaranteeing consistent product quality. The automatic operation of the lifting cylinder, inlet and outlet gates, and stepper motors ensures continuous and reliable heat setting production. The heat setting temperature is controlled by the steam temperature and airflow rate. The heat setting time is determined by the time it takes for the fiber bundles to fully wind around the anti-slip curling tube.

[0019] During the drying process, the readings of the temperature and humidity sensors are monitored in real time. The temperature sensor monitors the temperature when the wig first enters the drying chamber, thus preventing damage to the wig strands due to excessive temperature. The humidity sensor is located above the anti-slip curling and shaping tube to monitor the humidity of the airflow carrying moisture after the wig strands have dried. This allows for monitoring of the drying effect and enabling the exhaust fan and electric heating element to be turned off at any time.

[0020] To improve drying efficiency, the drying motor can be started. The drying motor drives the fan blades to rotate, blowing high-temperature air through the internal vents on the cylindrical plate upwards. This allows a larger amount of high-temperature air to enter the ventilation pipe and dry and dehumidify the wig strands wound on the pipe.

[0021] The sealing ring inside the outer tube connector provides a good seal, preventing high-temperature gas from passing between the outer circle of the inner tube connector and the inner circle of the outer tube connector during the drying process.

[0022] The tube body, anti-slip ridge strips, upper limit ring, lower limit ring, outer tube connector, and inner tube connector can be integrally injection molded from high-temperature resistant plastic material, allowing for mass production and low cost. The sealing ring is separately installed into the annular groove on the inner circle of the outer tube connector.

[0023] The ventilation holes have an elongated structure, which not only prevents the hair strands from slipping, but also maximizes the ventilation area of ​​the ventilation holes while ensuring the rigidity and strength of the tube.

[0024] Since the vertical series drying box for shaping tubes requires placing and connecting many anti-slip curled shaping tubes before drying, this invention sets up two vertical series drying boxes for shaping tubes, which improves drying efficiency and saves more space compared to belt conveyor heat shaping devices.

[0025] In summary, this invention first winds the fiber bundles onto the anti-slip curling and shaping tube, then places the anti-slip curling and shaping tube into a conveyor belt heat setting device for hot steam setting. Finally, several anti-slip curling and shaping tubes are connected in series and placed in a vertically connected drying box for batch drying. After drying, the fiber bundles are removed from the anti-slip curling and shaping tube to form curled wig bundles. The drying process uses negative pressure extraction + positive pressure air supply, with high-temperature air drying the wig bundles from the inside of the anti-slip curling and shaping tube to the outside, making the internal drying of the wig bundles faster and more uniform, with controllable temperature and humidity, and also preventing the wig bundles from tangling together when they are removed after drying.

[0037] In operation, the present invention first places the anti-slip curling and shaping tube 42 onto the pneumatic internal expansion clamps 41 on both sides of the dual-station switching winding device 32. The inner circle of the outer sleeve joint 7 at the lower end of the anti-slip curling and shaping tube 42 is fitted onto the pneumatic internal expansion clamps 41. The pneumatic internal expansion clamps 41 are activated, and they expand radially to press the outer sleeve joint 7, thus vertically positioning the anti-slip curling and shaping tube 42. The hollow shaft motor 40 of the winding rotation positioning component on the left side of the working position is then activated to drive the anti-slip curling and shaping tube 42 to rotate, gradually winding the fiber bundles onto the anti-slip curling and shaping tube 42 from bottom to top. When the fiber bundles on the left side of the anti-slip curling and shaping tube 42 are fully wound, the fibers are cut. The fiber bundle is rotated 180° by the station switching motor 36 driving the station switching disk 39. The right-side winding rotation positioning component rotates to the working position. The winding rotation positioning component, which is fully wrapped with fiber bundles, moves to the right-side tube changing position. Then, the hollow shaft motor 40 at the working position starts to drive the anti-slip curling and shaping tube 42 to rotate, gradually winding the fiber bundles onto the anti-slip curling and shaping tube 42 from bottom to top. At the same time, the pneumatic internal expansion clamp 41 at the right-side tube changing position is operated to radially retract, removing the anti-slip curling and shaping tube 42, which is fully wrapped with fiber bundles, from the pneumatic internal expansion clamp 41 and placing it on a positioning post 52 at the top left of the conveyor belt 50 of the belt-type heat setting device 33. Then, a new anti-slip roll... The shaping tube 42 is fitted onto the pneumatic internal expansion clamp 41 at the tube changing position. The pneumatic internal expansion clamp 41 is operated to expand radially, fixing the anti-slip shaping tube 42 and the pneumatic internal expansion clamp 41 together. After the anti-slip shaping tube 42 at the working position is fully wrapped with fiber bundles again, the above process is repeated. Each time, the anti-slip shaping tube 42 fully wrapped with fiber bundles is removed from the tube changing position and placed in front of a positioning post 52 at the top left side of the conveyor belt 50 of the belt-type heat setting device 33. Driven by a stepper motor, the drive pulley 46 of the belt-type heat setting device 33 drives the upper half of the conveyor belt 50 to move to the right a certain distance (this distance is equal to the distance between two adjacent positioning posts 52). (spacing), when the anti-slip curling and shaping tube 42, which is wrapped with fiber bundles, enters the shaping box 45 to the right, the automatic tube inlet door 48 opens. After moving to the right and entering the shaping box 45, the automatic tube inlet door 48 closes. The lifting cylinder 56 extends and drives the steam supply pipe 54 to move downward along the vertical guide rail 53. The short section air supply tube 57 at the bottom of the steam supply is inserted into the upper port of the inner tube connector 6 at the upper end of the anti-slip curling and shaping tube 42. High temperature steam is introduced into the tube body 1 of the anti-slip curling and shaping tube 42 through the main air supply pipe 55, the steam supply pipe 54 and the short section air supply tube 57. The steam is then passed outward through the air passage 2 on the tube body 1 to heat-shape the inside of the wig bundles wrapped around the outer circle of the tube body 1.Before each start of the stepper motor, the lifting cylinder 56 retracts upward, causing the lower end of the short air supply tube 57 to disengage from the upper port of the inner tube connector 6. After each displacement of the conveyor belt 50, the lifting cylinder 56 extends downward, causing the lower end of the short air supply tube 57 to insert into the upper port of the inner tube connector 6. This continues until all the anti-slip curled shaping tubes 42 are inserted into the positioning posts 52 inside the shaping box 45. Before each start of the stepper motor, the automatic tube exit door 49 opens first, and the rightmost heat-shaped anti-slip curled shaping tube 42 moves to the right out of the shaping box 45, thus removing the heat-shaped tube. After the anti-slip curling styling tube 42 has been shaped, it is removed from the positioning post 52 and placed into one of the vertically connected drying boxes 34. Following the above winding and heat-setting process, the heat-set anti-slip curling styling tubes 42 are placed one by one into the vertically connected drying box 34 until the box is full. Then the door is closed, and the vertically connected drying box 34 is started to dry the hair strands wound by the heat-set anti-slip curling styling tubes 42. During the drying process, the heat-set anti-slip curled shaping tubes 42 are placed into the second vertical series drying box 34 until it is almost full (there are 3-5 more anti-slip curled shaping tubes 42 remaining). Then, the first vertical series drying box 34 is closed, the door is opened, and the dried anti-slip curled shaping tubes 42 are removed from the box one by one. After all are removed, the second vertical series drying box continues drying. The box 34 is also basically full of anti-slip curling and shaping tubes 42. The door of the second vertical series drying box 34 is closed, and the second vertical series drying box 34 is started to dry the hair strands wound by the heat-set anti-slip curling and shaping tubes 42. During the drying process, the heat-set anti-slip curling and shaping tubes 42 are placed back into the first vertical series drying box 34. This continuous cycle ensures that the winding, heat-setting, and drying operations are carried out continuously, greatly improving production efficiency.

[0038] The specific process of placing the anti-slip curled shaping tubes 42 into the vertically connected drying oven 34 is as follows: First, open the oven door, and then install multiple anti-slip curled shaping tubes 42 sequentially from bottom to top on the last or front (inner) row of ventilation pipes 13. Next, insert a positioning rod 30 through the insertion hole on the crossbeam 29 into the inner insertion tube connector 6 at the uppermost anti-slip curled shaping tube 42. This positions a set of anti-slip curled shaping tubes 42 vertically connected components to prevent them from tipping over. Following this installation method, install a set of anti-slip curled shaping tubes 42 vertically connected components on each of the remaining ventilation pipes 13 and insert the positioning rod 30 for positioning.

[0039] The specific process of drying the fiber bundles wound on the anti-slip curled shaping tubes 42 in the vertical series drying oven 34 is as follows: close the oven door, start the exhaust fan 16, and turn on the electric heating tube 21. The oven body 10 generates negative pressure under the action of the exhaust fan 16. External air enters the cavity below the partition 17 through the external vent 20. The electric heating tube 21 heats the incoming cold air. The heated high-temperature air enters the cavity through the lower vent 22 and the air pipe 13 on the partition 17. The air enters the housing 10 through the air vent 2 on the tube body 1 inside the anti-slip curling and shaping tube 42 connected in series. As the high-temperature air passes through the air vent 2, it dries the inside of the wig strands wrapped around the outer circle of the tube body 1. Under the combined action of the high-temperature air inside and outside the anti-slip curling and shaping tube 42, the drying efficiency of the wig strands is greatly improved, ensuring that the inside of the wig strands is also completely dried. Finally, the airflow enters the air gathering hood 15 through the upper vent 14 on the top plate, and is then drawn upward by the exhaust fan 16.

[0040] The dual-station switching winding device 32 adopts a horizontal rotation switching method, allowing for tube changing operations at the tube-changing position while the winding operation is being performed at the working position. This improves the efficiency of fiber bundle winding. A pneumatic internal expansion clamp 41 is used to position and clamp the anti-slip curling and shaping tube 42, which is convenient and quick, reduces manual labor intensity, and improves work efficiency. The hollow shaft of the hollow shaft motor 40 directly serves as the air supply path for the pneumatic internal expansion clamp 41, resulting in a simple and compact structure. When the fiber bundle is wound onto the tube body 1, the anti-slip ridges 3 effectively position the fiber bundle, preventing it from sliding down the tube body 1.

[0041] The belt conveyor heat setting device 33 operates in an assembly line manner. Timing begins when the anti-slip curling setting tube 42 enters the setting box 45 and ends when it exits the box. The entire heat setting time is from the moment the tube enters until it exits. The anti-slip curling setting tube 42 moves from left to right within the box 45 using a stepping motion, achieving automated operation. During the heat setting process, hot steam enters from inside the anti-slip curling setting tube 42 and exits through the air vent 2. This process heat sets the fiber bundles wrapped around the outer circumference of the tube. This airflow ensures that the setting effect is essentially consistent throughout the fiber bundles, thus guaranteeing product quality consistency. The automatic operation of the lifting cylinder 56, the automatic inlet door 48, the automatic outlet door 49, and the stepper motor ensures the continuity and reliability of the heat setting assembly line production. The heat setting temperature is controlled by the temperature and volume of the hot steam. The heat setting time is determined by the time it takes for the fiber bundle to be fully wound around the anti-slip curling and setting tube 42.

[0042] During the drying process, the readings of temperature sensor 27 and humidity sensor 28 are monitored in real time. Temperature sensor 27 monitors the temperature when the hair strands first enter the drying chamber 10, thus avoiding damage to the hair strands due to excessive temperature. Humidity sensor 28 is located above the anti-slip curling and shaping tube 42 to monitor the humidity of the airflow carrying moisture after the hair strands are dried. This allows for monitoring of the drying effect, so that the exhaust fan 16 and electric heating tube 21 can be turned off at any time.

[0043] To improve drying efficiency, the drying motor 25 can be started. The drying motor 25 drives the fan blade 26 to rotate, blowing the high-temperature air through the inner vent 24 on the cylindrical plate 23 upward, so that a larger amount of high-temperature air enters the ventilation pipe 13 to dry and dehumidify the hair strands wound on the pipe body 1.

[0044] The sealing ring 8 inside the outer tube connector 7 provides a good seal, preventing high-temperature gas from passing between the outer circle of the inner tube connector 6 and the inner circle of the outer tube connector 7 during the drying process.

[0045] The tube body 1, anti-slip ridge strip 3, upper limit ring 4, lower limit ring 5, outer tube connector 7, and inner tube connector 6 can be integrally injection molded from high-temperature resistant plastic material, allowing for mass production and low cost. The sealing ring 8 is separately installed into the annular groove inside the outer tube connector 7.

[0046] The air vent 2 has an elongated hole structure, which not only prevents the hair strands from slipping, but also maximizes the air permeability area of ​​the air vent while ensuring the rigidity and strength of the tube body 1.

[0047] Since the vertical series drying box 34 for shaping tubes requires placing and connecting many anti-slip curled shaping tubes 42 in series before the drying operation, the present invention sets up two vertical series drying boxes 34 for shaping tubes, which improves the drying efficiency and saves more space compared with the belt conveyor heat shaping device 33.

[0048] The pneumatic internal expansion clamp 41, the automatic inlet gate 48, and the automatic outlet gate 49 in this invention are all existing conventional technologies, and their specific structures will not be described in detail.

[0049] The above embodiments illustrate the basic principles and features of the present invention, but are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the scope of protection of the present invention. Therefore, the scope of this patent and its protection should be determined by the appended claims.
