Description

Technical Field

[0001] The invention relates to the technical field of wig manufacturing, in particular to a chemical fiber hot-melt spinning device. Background Art

[0002] The spinning process of chemical fiber yarn is an important step in the production of chemical fiber textiles, and its quality directly affects the subsequent processing and the performance of the finished product. In traditional spinning devices, the spinning rate is often difficult to maintain stable, and the rate fluctuation is prone to uneven fiber thickness. This inconsistency not only affects the appearance of the fiber, but may also reduce the physical properties of the product, such as strength and elasticity. In addition, too fast a rate may lead to insufficient cooling, and the fiber fails to form a stable structure, which brings difficulties to subsequent processing. On the other hand, too slow a rate may delay production progress and affect overall efficiency.

[0003] In traditional chemical fiber production, the lack of control over the spinning rate and the limitations of cooling technology are superimposed on each other, further exacerbating quality problems. A spinning rate that is too fast can easily lead to incomplete cooling, excessively high fiber surface temperatures, and cause adhesion or deformation; while a rate that is too slow can reduce production efficiency and affect output. Traditional cooling devices mostly use a single air cooling method, which is greatly affected by ambient temperature and humidity and cannot provide uniform cooling conditions for the fibers. This technical bottleneck is particularly prominent in fiber production that requires high precision and high stability.

[0004] To this end, we provide a spinning mechanism that uses a constant range of pressure to effectively control the spinning rate, thereby improving the consistency and quality of fiber forming; the cooling gas humidification technology can provide a more uniform cooling environment for the chemical fiber yarn, ensuring that the fiber remains stable during the shaping process. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a chemical fiber hot melt spinning device.

[0006] The objective of the present invention is achieved as follows: a chemical fiber hot melt spinning device comprises a feeding mechanism, which supplies chemical fiber raw materials: a hot melt mechanism is connected to the front end of the feeding mechanism, which supplies raw materials to the hot melt mechanism; the hot melt mechanism heats and melts the chemical fiber raw materials; a spinning mechanism is connected to the front end of the hot melt mechanism, which supplies the hot-melt raw materials to the spinning mechanism, and the spinning mechanism spins the hot-melt raw materials; a cooling mechanism is provided at the lower end of the spinning mechanism, which cools the ejected chemical fiber.

[0007] Furthermore, the spinneret mechanism includes a spinneret, which is connected to a hot melt mechanism, and the hot melt mechanism supplies the hot-melted raw material into the spinneret; a plurality of spinneret holes are evenly arranged at the bottom of the spinneret, and the hot-melted raw material is discharged downward through the spinneret holes to form chemical fiber yarns.

[0008] Furthermore, a heating mechanism 1 is fixedly arranged on the side of the spinneret, and the heating mechanism 1 heats the side wall of the spinneret. An annular cylinder is arranged on the outer side of the heating mechanism 1.

[0009] When the present invention is used, raw materials are supplied to the hot melt mechanism through the feeding mechanism, and the feeding mechanism can feed the hot melt mechanism with a fixed quantity and speed. The specific structure is not technically limited as long as the above functions can be achieved.

[0010] The raw material is heated to a specified temperature by a hot melt mechanism until it becomes completely liquid. The above technical solution does not impose any technical limitation, as long as the above functions can be achieved. The heated liquid material is continuously transported to the lower part of the spinneret by the hot melt mechanism. The function of the hot melt mechanism to continuously transport the material forward is a prior art, and no further technical description is given, as long as the above functions can be achieved. The hot melt mechanism continuously transports the material and continuously pressurizes the material liquid in the spinneret. The material in the lower part of the spinneret is discharged through the spinneret holes at the lower part of the spinneret under pressure. After the chemical fiber is discharged from the spinneret, it is cooled by a cooling mechanism.

[0011] A heating mechanism on the outside of the spinneret heats the spinneret so that the liquid raw material is heated to a specified temperature. The heating mechanism heating the material to a specified temperature is a prior art and will not be described in detail.

[0012] The liquid material at the lower part of the spinneret may be subjected to uneven pressure during the process of the hot melt mechanism conveying the material and the process of discharging the chemical fiber yarn through the spinneret hole. For this reason, a pressure stabilizing mechanism is provided to control the pressure thereof within a certain range; that is, a constant pressure pump supplies gas to the upper part of the spinneret within a specified pressure range, and the pressure plate is pressed downward by the gas pressure to squeeze the liquid material, thereby achieving a certain range of pressure of the pressure plate to continuously squeeze the material, ensuring that the spinneret hole stably produces yarn within a certain pressure range. When the amount of material supplied to the spinneret by the feeding mechanism increases, the pressure of the liquid material below the spinneret increases, thereby driving the pressure plate to move upward, and the air pressure on the upper part of the spinneret increases. The air pressure sensor transmits the detected air pressure temperature to the controller, and the controller controls the solenoid valve six to exhaust air outward until the air pressure on the upper part of the spinneret drops to a specified range, and the solenoid valve six is ​​closed. The controller is a prior art, and no technical description is made, and it is sufficient to achieve the above functions.

[0013] In order to ensure that the pressure of the liquid material at the spinneret hole is always within a constant range, when the feeding mechanism suddenly supplies a large amount of material to the spinneret mechanism, in order to avoid the electromagnetic valve 6 being unable to discharge the gas on the top of the spinneret and reducing the pressure or the electromagnetic valve 6 being damaged, causing the entire equipment to fail to work properly, a deflation mechanism is provided. When the gas on the top of the spinneret cannot be discharged quickly and in time and the pressure reaches a certain value (that is, the air pressure on the top of the spinneret can push the closing plate upward to overcome the downward squeezing force of the spring on the closing plate), the closing plate moves upward, the spring is compressed, and the gas on the top of the spinneret is quickly discharged from the air hole 1 into the deflation cylinder and discharged outward through the air hole 2. The pressure of the spring can be changed by rotating the threaded rod, thereby changing the air pressure value that pushes the closing plate open. The above structure can cope with emergency situations and avoid equipment damage and shutdown.

[0014] The chemical fiber is cooled by a cooling mechanism, that is, gas is supplied to the air inlet tube through a fan. Since the air inlet tube is a tangential connection to the outer ring space, an annular wind direction can be formed in the outer ring space. The gas passes through the annular filter and enters the inner ring space. The annular filter filters impurities in the gas. After passing through the inner ring space, the gas is supplied to the middle through the annular exhaust net. An air guide plate is provided to change the flow direction of the gas in the inner ring space, that is, by rotating the annular plate (by rotating the push rod) and then driving the moving rod to move, the moving rod drives the air guide plate to rotate, and the inner ring wind flow angle is changed. Then the flow direction of the gas entering the cyclone is changed (generally a downward flowing annular wind direction).

[0015] The provision of spray head one and spray head two can realize spraying humidification and cooling of the gas, which can reduce the temperature of the gas and increase the cooling effect on the chemical fiber filaments; when the solenoid valve two is opened, the water pump supplies water to the drainage branch pipe, and the water enters the spray head two from the solenoid valve two. The spray head two sprays the outer ring space to humidify and cool the gas. Due to the provision of an annular filter, a large part of the atomized droplets are blocked in the outer ring space and cannot enter the inner ring space, which can reduce the temperature of the gas, adsorb and purify the dust in the air, and prevent a large amount of atomized droplets from entering the cyclone.

[0016] When solenoid valve one is opened and solenoid valve two is closed, the gas is humidified and cooled in the inner annular space. Since the annular exhaust network allows a large number of atomized droplets to pass through, the temperature of the gas entering the cyclone can be reduced and the humidity in the gas can be greatly increased.

[0017] Or opening solenoid valve 1 and solenoid valve 2 at the same time can effectively reduce the gas problem, highly adsorb and purify the dust in the air, and increase the humidity of the gas entering the cyclone.

[0018] Water is introduced into the corresponding drainage box through the drainage pipe through the outer ring drainage groove. Since an exhaust pipe is provided, even if the drainage box is a closed space, the water in the outer ring drainage groove can still enter the drainage box; open the electromagnetic valve 5, and the water in the drainage box is drained to the water tank 3 in the water supply tank through the water pipe 1. Since the outer ring space is continuously supplied with air, the wind pressure exerts a certain pressure on the drainage box, increasing the drainage speed of the drainage box to the water supply tank. The water pump draws the water in the water supply tank outward, increases the negative pressure in the water supply tank, and also has the function of increasing the drainage speed of the drainage box to the water supply tank. The water in the water tank 3 passes through the filter frame 2 to filter the large amount of dust contained in the water, and then enters the water tank 2.

[0019] The inner ring drainage groove introduces water into the corresponding drainage box through the drainage pipe. Since an exhaust pipe is provided, even if the drainage box is a closed space, the water in the inner ring drainage groove can still enter the drainage box; open the solenoid valve five, and the water in the drainage box is drained to the water tank two in the water supply tank through the water pipe one. Since the outer ring space is continuously supplied with air, the wind pressure has a certain pressure on the drainage box, increasing the drainage speed of the drainage box to the water supply tank. The water pump draws the water in the water supply tank outward, increases the negative pressure in the water supply tank, and also has the function of increasing the drainage speed of the drainage box to the water supply tank. The water in the water tank two passes through the filter frame one to filter the impurities contained in the water again, and then enters the water tank one. The water in the water tank one is pumped outward through the water supply pipe, thereby realizing water circulation.

[0020] When it is necessary to add water to the water supply tank, the electromagnetic valve 3 is opened to supply water to the water supply tank through the water pipe 2. The electromagnetic valve 4 can be opened as needed to open the air vent. When the water supply is large, gas can enter the water supply tank to avoid negative pressure in the water supply tank.

[0021] Beneficial effects: The device can realize the production of wig fiber chemical filaments. The spinneret mechanism with a constant range of pressure can effectively control the spinneret rate, thereby improving the consistency and quality of fiber molding; it avoids unstable spinneret rate, which causes the subsequent process to fail to keep up with the progress, or too fast spinneret causes poor cooling effect, or too fast spinneret causes different quality of front and back spinneret, and can realize cooling gas humidification of chemical fiber filaments, etc., which can provide a more uniform cooling environment for chemical fiber filaments and ensure that the fiber remains stable during the shaping process.

[0043] The drainage mechanism includes a drainage pipe 32 and an exhaust pipe 33. The upper end of the drainage pipe 32 is located at the bottom of the inner annular drainage groove, and the upper end of the exhaust pipe 33 is higher than the inner annular drainage groove. A drainage box 15 is arranged at the lower ends of the exhaust pipe 33 and the drainage pipe 32. The lower ends of the exhaust pipe 33 and the drainage pipe 32 are located in the upper part of the drainage box 15; a water pipe 17 is arranged at the lower end of the drainage box 15, and a solenoid valve 5 16 is arranged on the water pipe 17. The lower ends of the two water pipes 17 are connected to a water supply box 24. A filter frame 12 and a filter frame 2 11 are arranged in the water supply box 24. The filter frame 12 and the filter frame 2 11 are a closed rectangular structure. The filter frame is located in the filter frame 2 11. The filter frame 12 and the filter frame 2 11 divide the water supply box 24 into water tank 1, water tank 2 and water tank 3. Water tank 1 is located in the middle position, water tank 3 is located in the outer position, and water tank 2 is located between water tank 1 and water tank 3. The water pipe 17 of the drainage mechanism corresponding to the outer ring drainage groove is located above the water tank three, and the water in the outer ring drainage groove enters the water tank three; the water pipe 17 of the drainage mechanism corresponding to the inner ring drainage groove is located above the water tank two, and the water in the inner ring drainage groove enters the water tank two. A water supply pipe is arranged through the middle of the water supply tank 24, and the bottom of the water supply pipe is located at the bottom of the water tank one. A water pump 35 is arranged on the water supply pipe, and two water supply branches 38 are arranged at the output end of the water pump 35. The water supply branch pipes 38 are respectively provided with a solenoid valve 1 37 and a solenoid valve 2 36. The water supply branch pipe 38 on the solenoid valve 1 37 is connected to the spray head 19, and the water supply branch pipe 38 on the solenoid valve 2 36 is connected to the spray head 2 18; a water pipe 2 is arranged on the water supply tank 24, a solenoid valve 3 34 is arranged on the water pipe 2, and an air discharge port is arranged on the water supply tank 24 on the water tank one, and a solenoid valve 4 is arranged at the air discharge port.

[0044] When the present invention is used, raw materials are supplied to the hot melt mechanism through the feeding mechanism 3, and the feeding mechanism 3 can feed the hot melt mechanism with a fixed quantity and speed. There is no technical limitation on the specific structure, as long as the above functions can be achieved.

[0045] The raw material is heated to a specified temperature by a hot melt mechanism until it becomes completely liquid. The above technical solution does not impose any technical limitation, as long as the above functions can be achieved. The heated liquid material is continuously transported to the lower part of the spinneret 6 by the hot melt mechanism. The function of the hot melt mechanism to continuously transport the material forward is a prior art, and no further technical description is given, as long as the above functions can be achieved. The hot melt mechanism continuously transports the material and continuously pressurizes the material liquid in the spinneret 6. The material in the lower part of the spinneret 6 is subjected to pressure and is discharged through the spinneret holes in the lower part of the spinneret 6. After the spinneret 6 discharges the chemical fiber, the chemical fiber is cooled by a cooling mechanism.

[0046] The heating mechanism 14 on the outside of the spinneret 6 heats the spinneret 6 so that the liquid raw material is heated to a specified temperature. The heating mechanism 14 heats the material to a specified temperature as a prior art and will not be described in detail.

[0047] The liquid material at the lower part of the spinneret 6 may be subjected to uneven pressure during the process of the hot melt mechanism conveying the material and the process of discharging the chemical fiber through the spinneret hole. For this reason, a pressure stabilizing mechanism is provided to control the pressure thereof within a certain range; that is, the constant pressure pump 21 supplies gas to the upper part of the spinneret 6 within a specified pressure range, and the pressure plate 26 is pressed downward by the gas pressure to squeeze the liquid material, thereby achieving a certain range of pressure of the pressure plate 26 to continuously squeeze the material, ensuring that the spinneret hole stably produces filaments within a certain pressure range. When the amount of material supplied to the spinneret 6 by the feeding mechanism 3 increases, the pressure of the liquid material below the spinneret 6 increases, thereby driving the pressure plate 26 to move upward, and the air pressure on the upper part of the spinneret 6 increases. The air pressure sensor 20 transmits the detected air pressure temperature to the controller, and the controller controls the solenoid valve 6 22 to exhaust air outward until the air pressure on the upper part of the spinneret 6 drops to a specified range, and the solenoid valve 6 22 is closed; the controller is a prior art, and no technical description is given, and it is sufficient to achieve the above functions.

[0048] In order to ensure that the pressure of the liquid material at the spinneret hole is always within a constant range, when the feeding mechanism 3 suddenly supplies a large amount of material to the spinneret mechanism, in order to avoid the electromagnetic valve 6 22 being unable to discharge the gas on the top of the spinneret 6 to reduce the pressure or the electromagnetic valve 6 22 being damaged, causing the entire device to fail to work properly, a deflation mechanism 23 is provided. When the gas on the top of the spinneret 6 cannot be discharged quickly and in time and the pressure reaches a certain value (i.e., the air pressure on the top of the spinneret 6 can push the closing plate 2306 upward to overcome the squeezing force of the spring 2302 on the closing plate 2306 downward), the closing plate 2306 moves upward, the spring 2302 is compressed, and the gas on the top of the spinneret 6 is quickly discharged from the air hole 1 2307 to the deflation cylinder 2301 and discharged outward through the air hole 2 2304. The pressure on the spring 2302 can be changed by rotating the threaded rod 2303, thereby changing the air pressure value for pushing the closing plate 2306 open. The above structure can cope with emergency situations and avoid equipment damage and shutdown.

[0049] The chemical fiber is cooled by the cooling mechanism, that is, the air is supplied to the air inlet tube 8 by the fan 10. Since the air inlet tube is tangentially connected to the outer annular space, an annular wind direction can be formed in the outer annular space. The gas passes through the annular filter 5 and enters the inner annular space. The annular filter 5 filters the impurities in the gas. After passing through the inner annular space, the gas is supplied to the middle through the annular exhaust net 13. The wind guide plate 29 is provided to change the flow direction of the gas in the inner annular space, that is, by rotating the annular plate 4 (by rotating the push rod 31) and then driving the moving rod 28 to move, the moving rod 28 drives the wind guide plate 29 to rotate, and the change of the flow angle of the inner annular wind is realized. Then the flow direction of the gas entering the cyclone 9 is changed (generally a downward flowing annular wind direction).

[0050] The provision of spray head 19 and spray head 2 18 can realize spraying humidification and cooling of the gas, which can reduce the temperature of the gas and increase the cooling effect on the chemical fiber filaments; when the solenoid valve 2 36 is opened, the water pump 35 supplies water to the drainage branch pipe, and the water enters the spray head 2 18 from the solenoid valve 2 36. The spray head 2 18 sprays the outer ring space to humidify and cool the gas. Due to the provision of the annular filter 5, a large part of the atomized droplets are blocked in the outer ring space and cannot enter the inner ring space, which can reduce the temperature of the gas, adsorb and purify the dust in the air, and prevent a large amount of atomized droplets from entering the cyclone 9.

[0051] When the solenoid valve 1 37 is opened and the solenoid valve 2 36 is closed, the gas is humidified and cooled in the inner annular space. Since the annular exhaust net 13 allows a large amount of atomized droplets to pass through, the temperature of the gas entering the cyclone 9 can be reduced and the humidity in the gas can be greatly increased.

[0052] Alternatively, opening the electromagnetic valve 1 37 and the electromagnetic valve 2 36 at the same time can effectively reduce the gas problem, highly adsorb and purify the dust in the air, and increase the humidity of the gas entering the cyclone 9.

[0053] Water is introduced into the corresponding drainage box 15 through the outer ring drainage groove through the drainage pipe 32. Since the exhaust pipe 33 is provided, even if the drainage box 15 is a closed space, the water in the outer ring drainage groove can still enter the drainage box 15; the electromagnetic valve 5 16 is opened, and the water in the drainage box 15 is drained to the water tank 3 in the water supply tank 24 through the water pipe 1 17. Since the outer ring space is continuously supplied with air, the wind pressure has a certain pressure on the drainage box 15, increasing the drainage speed of the drainage box 15 to the water supply tank 24. The water pump 35 pumps the water in the water supply tank 24 outward, increases the negative pressure in the water supply tank 24, and also has the function of increasing the drainage speed of the drainage box 15 to the water supply tank 24. The water in the water tank 3 passes through the filter frame 2 11 to filter a large amount of dust contained in the water, and then enters the water tank 2.

[0054] The inner ring drainage groove introduces water into the corresponding drainage box 15 through the drainage pipe 32. Since the exhaust pipe 33 is provided, even if the drainage box 15 is a closed space, the water in the inner ring drainage groove can still enter the drainage box 15; open the electromagnetic valve 5 16, and the water in the drainage box 15 is drained to the water tank 2 in the water supply box 24 through the water pipe 1 17. Since the outer ring space is continuously supplied with air, the wind pressure has a certain pressure on the drainage box 15, increasing the drainage speed of the drainage box 15 to the water supply box 24. The water pump 35 pumps the water in the water supply box 24 outward, increases the negative pressure in the water supply box 24, and also has the function of increasing the drainage speed of the drainage box 15 to the water supply box 24. The water in the water tank 2 passes through the filter frame 1 12 to filter the impurities contained in the water again, and then enters the water tank 1. The water in the water tank 1 is pumped outward through the water supply pipe, thereby realizing water circulation.

[0055] When it is necessary to replenish water in the water supply tank 24, water is supplied to the water supply tank 24 through the water pipe 2 by opening the electromagnetic valve 34. The electromagnetic valve 4 can be opened as needed to open the air vent, and when the water supply is large, gas can enter the water supply tank 24 to avoid negative pressure in the water supply tank 24.
