Description

Technical Field

[0001] The invention relates to the technical field of fiber false twist spinning, in particular to a fiber false twist spinning device and a spinning process for composite fibers. Background Art

[0002] When the existing false twisting machine is false twisting the long fibers, since there are some fiber fluffs on the polyester long fibers, when the fibers enter the false twisting machine for processing, the fluffs on the fibers will fall into the false twisting machine, which can easily cause contamination inside the false twisting machine, increase the probability of damage to the false twisting machine, and also increase the difficulty of cleaning the fluffs inside the false twisting machine. The false twisting machine needs to be stopped to clean it, which reduces the efficiency of false twisting of the polyester long fibers.

[0003] Chinese patent application CN118563468A discloses a false twisting device for polyester staple fibers, comprising a workbench and a false twisting machine body fixedly arranged on the top of the workbench, a winding structure symmetrically arranged on the top of the workbench, a cleaning structure arranged on the outside of the winding structure, the cleaning structure comprising: a mounting shell, the mounting shell being movably arranged on the front side of the winding structure, a through groove being provided on the end face of the mounting shell away from the winding structure, a support assembly for limiting the position of the mounting shell being symmetrically arranged on the front side of the mounting shell; a cleaning roller, the cleaning roller being movably arranged in the inner cavity of the mounting shell, the cleaning roller being used for cleaning the polyester fibers on the winding structure; and a mounting assembly, the mounting assembly being fixedly arranged on the ends of the mounting shell and the cleaning roller, the mounting assembly being used for limiting the position of the cleaning roller in the inner cavity of the mounting shell.

[0004] The above scheme can prevent the fluff in the unwinding from entering the false twist spinning equipment. Although the above scheme is for the processing of short fibers, it can also solve the same problem when applied to the processing of long fibers. When the false twist spinning equipment is false twisting the fibers, the false twist rollers in the equipment will also cause the fluff in the fibers to adhere to the false twist rollers when processing the fibers. If it is in operation for a long time, the fluff attached to the false twist rollers will inevitably affect the fibers produced subsequently, that is, more fluff will be attached to the fibers produced subsequently, thereby affecting the quality of the fibers finally produced. Summary of the invention

[0005] In view of the above problems, a fiber false twist spinning device and a spinning process for composite fibers are provided. Before cleaning, the lifting frame is at the highest position of its own moving stroke. Since the false twist rollers are distributed in an equilateral triangle, and the false twist wheels on each false twist roller are arranged in a staggered manner, that is, in the vertical direction, two adjacent false twist wheels do not come from the same false twist roller. In the vertical direction, there is only one false twist wheel at the same height, and the false twist wheels arranged on different false twist rollers have the same thickness. Therefore, after each cleaning contact of the cleaning brush, the lifting frame descends in the vertical direction. The distance the lifting frame descends is the same as the sum of the thickness of the false twist roller and the diameter of the fiber rope. For the convenience of expression, the distance the lifting frame descends each time will be referred to as the specified The lifting frame drives the cleaning brush to clean the end surface of the false twist wheel from top to bottom in the vertical direction. It is worth noting that the lifting frame can only be lifted and lowered in the vertical direction. In this way, when the lifting frame descends in the vertical direction, one of the three cleaning brushes arranged on the lifting frame must correspond to the false twist wheel at the same height. The cleaning brush corresponding to the false twist wheel extends out when the lifting frame stops moving, and cleans the end surface of the false twist wheel. During cleaning, the lifting frame at the highest position is in a stationary state. At this time, one of the cleaning brushes in the lifting frame extends out in the horizontal direction and contacts the end surface of the false twist wheel at the same height. The height position of the false twist wheel is at the highest position of all vertically arranged false twist wheels. Due to the bristles of the cleaning brush The brush is made of nylon material. When the bristles of the cleaning brush are in the process of friction, static electricity is likely to occur. After the cleaning brush is extended from the cleaning cavity of the lifting frame, it can contact the end face of the false twist wheel and rotate around the axis of the cleaning brush itself. In this way, the bristles of the cleaning brush can rub against the end face of the false twist wheel during rotation. The false twist wheel here is made of ceramic material. This is because when the false twist wheel made of ceramic material contacts with the cleaning brush, the cleaning brush is more likely to generate static electricity, and the cleaning brush is not easy to damage the false twist wheel when cleaning and absorbing hair. When the cleaning brush cleans the end face of the false twist wheel, the false twist wheel rotates synchronously with the false twist roller, so that the end face of the false twist wheel after one rotation can be completely swept by the cleaning brush. When the cleaning brush rotates to the preset rated value, the false twist wheel will be smooth and smooth. After a period of time, the cleaning brush retracts into the cleaning chamber in the horizontal direction. After entering the cleaning chamber, the cleaning brush stops rotating, and high-speed air is introduced into the cleaning chamber. The static electricity on the cleaning brush gradually disappears. Under the action of the high-speed air, the fluff attached to the cleaning brush can be cleaned off. While the cleaning brush retracts into the cleaning chamber, the lifting frame descends a specified distance in the vertical direction. Subsequently, the cleaning brush corresponding to the false twist wheel at the same height as the lifting frame extends out and cleans the end surface of the false twist wheel, and so on, until the false twist wheel at the lowermost side. In this way, the fluff attached to the end surface of the false twist wheel can be cleaned without stopping the machine. At the same time, since the cleaning brush can generate static electricity during cleaning, the fluff is prevented from flying everywhere when being cleaned.

[0006] In order to solve the problems of the prior art, the present invention provides a fiber false twist spinning device, comprising three false twist rollers distributed in an equilateral triangle, the false twist rollers are provided with false twist wheels, and the false twist wheels on different false twist rollers are staggered in the vertical direction; a lifting frame which is lifted and lowered in the vertical direction is provided on the outer sleeves of the three false twist rollers, and three cleaning chambers are provided on the lifting frame, and the three cleaning chambers correspond to the three false twist rollers respectively, and a cleaning brush is provided in the cleaning chamber to slide in the horizontal direction, and the bristles of the cleaning brush are made of nylon. During cleaning, the lifting frame drives the cleaning brush to lift and lower in the vertical direction from the highest position, and the distance that the lifting frame descends each time is equal to the sum of the thickness of the false twist wheel and the diameter of the fiber rope. After the lifting frame stops, the cleaning brush extends out, and the extended cleaning brush contacts the end face of the false twist wheel and rotates around the axis of the cleaning brush itself. The rotating cleaning brush generates static electricity due to friction, and the cleaning brush absorbs the fluff on the end face of the false twist wheel through the static electricity.

[0009] Preferably, a sliding door is provided on one end of the cleaning chamber toward the false twist wheel so as to slide in a horizontal direction. The sliding door is driven by electricity. When the cleaning brush is retracted into the cleaning chamber for cleaning, the sliding door is closed. A fan is rotatably provided at the upper part of the cleaning chamber. A collecting unit is connected to the lower part of the cleaning chamber. The collecting unit is used to collect hair. After the cleaning brush is retracted into the cleaning chamber, the fan is activated. The fan blows outside air into the cleaning chamber from top to bottom in a vertical direction. The flowing airflow carries the hair into the collecting unit.

[0015] The present invention also relates to a spinning process of composite fibers, which uses a fiber false twist spinning device, and the specific steps are as follows:

[0016] S1. The lifting frame rises to the highest position, the cleaning brush on the lifting frame extends horizontally and contacts the end face of the false twist wheel at the highest position, the cleaning brush rotates around its own axis, the false twist wheel rotates around the axis of the false twist roller, after the false twist wheel rotates one circle, the cleaning brush completely sweeps the end face of the false twist wheel, static electricity is generated when the cleaning brush rotates, and an adsorption force is generated on the fluff, and the cleaning brush retracts into the cleaning chamber after rotating for the rated rotation time.

[0017] S2. A high-speed airflow is generated in the cleaning chamber to blow out the fluff attached to the cleaning brush, and at the same time the lifting frame descends. The height to which the lifting frame descends is the same as the sum of the thickness of the false twist roller and the diameter of the fiber rope. Subsequently, the cleaning brush corresponding to the false twist wheel at the same height as the lifting frame extends out and rotates. During the descent of the lifting frame, the cleaning brush on the lifting frame that can contact the end surface of the false twist wheel after being extended needs to be extended until the lifting frame descends to the lowest position. After the cleaning brush cleans the lower end surface of the false twist wheel located at the lowest side, the cleaning is completed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Before cleaning, the lifting frame is at the highest position of its own moving stroke. Since the false twist rollers are distributed in an equilateral triangle, and the false twist wheels on each false twist roller are arranged in a staggered manner, that is, in the vertical direction, two adjacent false twist wheels will not come from the same false twist roller. In the vertical direction, there is only one false twist wheel at the same height, and the false twist wheels set on different false twist rollers have the same thickness. Therefore, after each cleaning contact of the cleaning brush, the lifting frame will descend in the vertical direction. The distance the lifting frame descends is the same as the sum of the thickness of the false twist roller and the diameter of the fiber rope. For the convenience of expression, the distance the lifting frame descends each time will be called the specified distance. The lifting frame drives the cleaning brush to clean the false twist from top to bottom in the vertical direction. It is worth noting that the lifting frame can only be lifted and lowered in the vertical direction. In this way, when the lifting frame descends in the vertical direction, one of the three cleaning brushes arranged on the lifting frame must correspond to the false twist wheel at the same height. The cleaning brush corresponding to the false twist wheel extends out when the lifting frame stops moving, and cleans the end surface of the false twist wheel. When cleaning, the lifting frame at the highest position is in a static state. At this time, one of the cleaning brushes in the lifting frame extends out in the horizontal direction and contacts the end surface of the false twist wheel at the same height. The height position of the false twist wheel is at the highest position of all vertically arranged false twist wheels. Since the bristles of the cleaning brush are made of nylon, when the bristles of the cleaning brush are Static electricity is likely to occur during the friction process, and the cleaning brush can contact the end face of the false twist wheel and rotate around the axis of the cleaning brush itself after extending from the cleaning cavity of the lifting frame, so that the bristles of the cleaning brush can rub against the end face of the false twist wheel during rotation. The false twist wheel here is made of ceramic material. This is because the cleaning brush is more likely to generate static electricity when the false twist wheel made of ceramic material contacts with the cleaning brush, and the cleaning brush is not easy to damage the false twist wheel when cleaning and absorbing hair. When the cleaning brush cleans the end face of the false twist wheel, the false twist wheel rotates synchronously with the false twist roller, so that the end face of the false twist wheel after one rotation can be completely swept by the cleaning brush. When the cleaning brush rotates to the preset rated time, the cleaning brush moves along the water The cleaning brush is retracted into the cleaning chamber in the horizontal direction. After entering the cleaning chamber, the cleaning brush stops rotating, and high-speed air is introduced into the cleaning chamber. The static electricity on the cleaning brush gradually disappears. Under the action of the high-speed air, the fluff attached to the cleaning brush can be cleaned off. At the same time, the cleaning brush is retracted into the cleaning chamber, the lifting frame descends a specified distance in the vertical direction, and then the cleaning brush corresponding to the false twist wheel at the same height as the lifting frame extends out and cleans the end surface of the false twist wheel, and so on, until the false twist wheel at the lowermost side. In this way, the fluff attached to the end surface of the false twist wheel can be cleaned without stopping the machine. At the same time, since the cleaning brush can generate static electricity during cleaning, the fluff is prevented from flying everywhere when being cleaned.

[0020] 2. The hair cleaned out of the cleaning chamber is collected by setting a collecting unit, and a rubbing unit is set at the bottom of the sponge to avoid the bottom of the sponge being blocked by hair, ensuring that the airflow can be discharged smoothly from the sponge.

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1-Figure 3 A fiber false twist spinning device, comprising three false twist rollers 1 distributed in an equilateral triangle, each false twist roller 1 being provided with a false twist wheel 11, and the false twist wheels 11 on different false twist rollers 1 are arranged alternately in the vertical direction; a lifting frame 4 which is lifted and lowered in the vertical direction is provided on the outer sleeve of the three false twist rollers 1, and three cleaning chambers 41 are provided on the lifting frame 4, and the three cleaning chambers 41 correspond to the three false twist rollers 1 respectively, and a cleaning brush 3 is provided in the cleaning chamber 41 to slide in the horizontal direction, and the bristles of the cleaning brush 3 are made of nylon. When cleaning, the lifting frame 4 moves from The highest position drives the cleaning brush 3 to rise and fall in the vertical direction, and the distance that the lifting frame 4 descends each time is equal to the sum of the thickness of the false twist wheel 11 and the diameter of the fiber rope 2. After the lifting frame 4 stops, the cleaning brush 3 extends out, and the extended cleaning brush 3 contacts the end face of the false twist wheel 11 and rotates around the axis of the cleaning brush 3. The rotating cleaning brush 3 generates static electricity due to friction, and the cleaning brush 3 absorbs the fluff on the end face of the false twist wheel 11 through static electricity. The cleaning brush 3 is preset with a rated rotation time. After the cleaning brush 3 rotates to the rated rotation time, it retracts into the cleaning chamber 41.

[0036] The fiber passes through the center of the three false twist rollers 1 and passes through the staggered false twist wheels 11 in turn, and is false-twisted by the staggered false twist wheels 11 to form a fiber rope 2. It is worth noting that there are two materials for the existing false twist wheels 11, one of which is ceramic material, but the false twist wheel 11 made of ceramic material is easy to damage the outer fibers of the fiber rope 2 when false twisting the fibers, that is, more fluff is generated, but the service life is long; the other is rubber material, and the false twist wheel 11 made of rubber material is not easy to damage the outer part of the fiber rope 2 when false twisting the fibers, but when the fiber rope 2 is false twisted, the false twist wheel 11 is greatly worn by the fiber rope 2, that is, the service life of the false twist wheel 11 supported by the rubber material is short, but no matter which false twist wheel 11 is used, there is no The method is to completely avoid the generation of fluff. The generated fluff will adhere to the false twist wheel 11. When the fluff adheres too much, the fluff will be mixed with the false twisted fiber rope 2, which will lead to a decrease in the output quality of the fiber rope 2. The traditional method to solve the above problem is to stop the machine for cleaning, but this will lead to a decrease in production. In order to overcome the above problem, a lifting frame 4 is set on the periphery of the false twist roller 1, and a cleaning brush 3 is set on the lifting frame 4. The specific working principle is as follows: before cleaning, the lifting frame 4 is at the highest position of its own moving stroke. Since the false twist rollers 1 are distributed in an equilateral triangle, and the false twist wheels 11 on each false twist roller 1 are staggered, that is, in the vertical direction, two adjacent false twist wheels 11 will not come from the same false twist roller 1, and in the vertical direction There is only one false twist wheel 11 at the same height, and the false twist wheels 11 arranged on different false twist rollers 1 have the same thickness. Therefore, after each cleaning contact of the cleaning brush 3, the lifting frame 4 is lowered in the vertical direction. The distance that the lifting frame 4 is lowered is the same as the sum of the thickness of the false twist roller 1 and the diameter of the fiber rope 2. For the convenience of expression, the distance that the lifting frame 4 is lowered each time will be referred to as the specified distance. The lifting frame 4 drives the cleaning brush 3 to clean the end surface of the false twist wheel 11 from top to bottom in the vertical direction. It is worth noting that the lifting frame 4 can only be lifted and lowered in the vertical direction. In this way, when the lifting frame 4 is lowered in the vertical direction, one of the three cleaning brushes 3 arranged on the lifting frame 4 must correspond to the false twist wheel 11 at the same height, and the cleaning brush 3 corresponding to the false twist wheel 11 The cleaning brush 3 extends out when the lifting frame 4 stops moving, and cleans the end surface of the false twist wheel 11. During the cleaning, the lifting frame 4 located at the highest position is in a stationary state. At this time, a cleaning brush 3 in the lifting frame 4 extends out in the horizontal direction and contacts the end surface of the false twist wheel 11 at the same height. The height position of the false twist wheel 11 is at the highest position of all vertically arranged false twist wheels 11. Since the bristles of the cleaning brush 3 are made of nylon, static electricity is easily generated during the friction process. After the cleaning brush 3 is extended from the cleaning cavity 41 of the lifting frame 4, it can contact the end surface of the false twist wheel 11 and rotate around the axis of the cleaning brush 3 itself. In this way, the bristles of the cleaning brush 3 can rub against the end surface of the false twist wheel 11 during rotation.Here, the false twist wheel 11 is made of ceramic material. This is because when the false twist wheel 11 made of ceramic material comes into contact with the cleaning brush 3, the cleaning brush 3 is more likely to generate static electricity, and the cleaning brush 3 is not easy to damage the false twist wheel 11 when cleaning and absorbing the fluff. When the cleaning brush 3 cleans the end surface of the false twist wheel 11, the false twist wheel 11 rotates synchronously with the false twist roller 1, so that the end surface of the false twist wheel 11 after one rotation can be completely swept by the cleaning brush 3. When the cleaning brush 3 rotates to a preset rated time, the cleaning brush 3 retracts into the cleaning chamber 41 in the horizontal direction. After entering the cleaning chamber 41, the cleaning brush 3 no longer rotates, and high-speed air is introduced into the cleaning chamber 41. The static electricity on the cleaning brush 3 gradually disappears, and under the action of high-speed air, the fluff attached to the cleaning brush 3 can be cleaned off, and while the cleaning brush 3 retracts into the cleaning chamber 41, the lifting frame 4 descends a specified distance in the vertical direction, and then the cleaning brush 3 corresponding to the false twist wheel 11 at the same height as the lifting frame 4 extends out and cleans the end surface of the false twist wheel 11, and so on, until the lowest false twist wheel 11, so that the fluff attached to the end surface of the false twist wheel 11 can be cleaned without stopping the machine, and at the same time, because the cleaning brush 3 can generate static electricity during cleaning, the fluff is prevented from flying everywhere when being cleaned.

[0037] Reference Figure 1-Figure 11 : The distance that the lifting frame 4 descends each time is called the designated distance. During the descent of the lifting frame 4, the lifting frame 4 has a highest position and a second highest position. At the same time, the lifting frame 4 also has a lowest position and a second lowest position. When the lifting frame 4 is at the highest position, the second highest position, the lowest position and the second lowest position, only one cleaning brush 3 is extended. When the lifting frame 4 is at other heights, two cleaning brushes 3 are extended each time.

[0038] This is because the false twist roller 1 has two upper and lower end surfaces. Taking the case where the lifting frame 4 is located at the highest position and the second highest position as an example, a false twist wheel 11 is arranged in the vertical direction at this time, and for the sake of ease of understanding, the false twist wheel 11 at the highest position of the vertical arrangement is called the highest twist wheel. When cleaning the upper end surface of the highest twist wheel, the lifting frame 4 is located at the highest position, and the cleaning brush 3 on the lifting frame 4 extends out and cleans the upper end surface of the highest twist wheel. After cleaning, the cleaning brush 3 retracts into the cleaning chamber 41, and then the lifting frame 4 descends a specified distance. At this time, the cleaning brush 3 is driven by the lifting frame 4 to descend to the side of the highest twist wheel at the same height, and the cleaning brush 3 cannot be extended from the cleaning chamber 41. When the lifting frame 4 descends again, the cleaning brush 3 is located at the lower end of the highest twist wheel. At this time, the cleaning brush 3 is extended horizontally again, and the cleaning brush 3 cleans the lower end surface of the highest twist wheel.

[0039] Reference Figure 7 and Figure 8An electric push rod 42 is horizontally arranged on one side of the cleaning chamber 41 away from the false twisting roller 1, and the output end of the electric push rod 42 is rotatably matched with the end of the cleaning brush 3, and the cleaning brush 3 moves synchronously with the output end of the electric push rod 42, and a first driving unit 43 for driving the cleaning brush 3 to rotate is arranged on the cleaning brush 3, and the first driving unit 43 includes a rotating sleeve 432, and the rotating sleeve 432 is sleeved on the cleaning brush 3, and the rod body interface of the cleaning brush 3 is a non-circular structure, and the rod body of the cleaning brush 3 passes through the rotating sleeve 432 and slidably matches with the rotating sleeve 432, and the outer fixed sleeve of the rotating sleeve 432 is provided with a first gear ring 431.

[0040] The first driving unit 43 also includes a first gear 433 and a first rotation driver 434. The first gear 433 is rotatably arranged on one side of the first gear ring 431. The first gear 433 and the first gear ring 431 are meshed with each other. The first rotation driver 434 is arranged at the end of the first gear 433. The output end of the first rotation driver 434 is fixedly connected to the end of the first gear 433. The first rotation driver 434 is preferably a servo motor. When the first rotation driver 434 is started, the first gear 433 can drive the first gear ring 431 to rotate, thereby causing the rotating sleeve 432 to drive the cleaning brush 3 to rotate. After the rated rotation time is reached, the first rotation driver 434 stops running. Since the end of the cleaning brush 3 is rotationally matched with the output end of the electric push rod 42, when the first driving unit 43 drives the cleaning brush 3 to rotate, the electric push rod 42 will not affect the rotation of the cleaning brush 3.

[0041] Reference Figure 6 , Figure 7 and Fig.10 : A sliding door 411 is provided on one end of the cleaning chamber 41 toward the false twist wheel 11 so as to slide in the horizontal direction. The sliding door 411 is driven by electricity. When the cleaning brush 3 is retracted into the cleaning chamber 41 for cleaning, the sliding door 411 is closed. A fan 44 is provided for rotation at the upper part of the cleaning chamber 41. A collecting unit 45 is connected to the lower part of the cleaning chamber 41. The collecting unit 45 is used for collecting hair fluff. After the cleaning brush 3 is retracted into the cleaning chamber 41, the fan 44 is activated. The fan 44 blows outside air into the cleaning chamber 41 from top to bottom in the vertical direction. The flowing airflow carries the hair fluff into the collecting unit 45.

[0042] When the cleaning brush 3 is retracted into the cleaning chamber 41, the sliding door 411 is closed and the cleaning brush 3 stops rotating. At this time, the bristles of the cleaning brush 3 are no longer rubbed, and the static electricity on the bristles gradually dissipates, and the adsorption force of the bristles of the cleaning brush 3 on the fluff decreases. At this time, the fan 44 blows the outside air into the cleaning chamber 41 in a vertical direction. The flowing air blows the fluff on the cleaning brush 3 off and brings it into the collection unit 45. After the cleaning is completed and the cleaning brush 3 needs to be extended again, the sliding door 411 slides open, and then the cleaning brush 3 is extended from the cleaning chamber 41.

[0043] Reference Fig.11 The collecting unit 45 includes a collecting bin 451 disposed on one side of the lifting frame 4, a sponge 452 being disposed in the collecting bin 451, the sponge 452 forming a filter chamber in the collecting bin 451, an extension tube 453 being connected to the bottom of the cleaning chamber 41, the extension tube 453 passing through the sponge 452 and extending to the bottom of the collecting chamber, the collecting chamber is filled with water, and the water level in the collecting chamber is flush with the lower end surface of the sponge 452.

[0044] The water level in the collecting chamber is set to be the same as the height of the lower end surface of the sponge 452, so that the fluff entering the collecting chamber 451 can be successfully intercepted by the sponge 452, and the air can be discharged through the sponge 452, and the water stored in the collecting chamber will not be sprayed out from the sponge 452.

[0045] Reference Figure 4 , Figure 5 and Fig.11 : The sponge 452 is an annular structure, the guide shell 454 is sleeved on the periphery of the sponge 452 and fixedly set on the collecting bin 451, the guide shell 454 is fixedly connected to the outer ring of the sponge 452, the guide shell 454 is an inverted funnel-shaped structure, the upper opening of the guide shell 454 is smaller than the lower opening, and a rubbing unit 455 is provided at the bottom of the sponge 452, the rubbing unit 455 includes a rubbing rod 4551, the rubbing rod 4551 is in contact with the lower end face of the sponge 452, and the rubbing rod 4551 can rotate around the axis of the sponge 452.

[0046] Since the water level in the collecting chamber is at the same height as the lower end surface of the sponge 452, and the mass of the fluff is relatively light, some of the fluff floats on the water surface. The fluff floating on the water surface will block the lower end surface of the sponge 452. Therefore, it is necessary to clean the lower end surface of the sponge 452 in time to avoid the situation where the airflow cannot be discharged smoothly. A rubbing rod 4551 is provided at the bottom of the sponge 452. The rubbing rod 4551 is rotated around the axis of the sponge 452 at the bottom of the sponge 452 so that the rubbing rod 4551 rubs the fluff located at the bottom of the sponge 452. When a large amount of fluff is rubbed into strips, the mass of the fluff after being rubbed into strips increases and sinks to the bottom of the collecting chamber 451. A second driving mechanism for the rubbing rod 4551 to rotate around the axis of the sponge 452 is provided at the upper part of the rubbing rod 4551. Unit, the second driving unit includes a second gear ring 4552, a second gear 4553 and a second rotation driver 4554, the second gear ring 4552 is rotatably set on the upper part of the sponge 452, and an extension ring is fixedly set on the lower part of the second gear ring 4552, and the extension ring extends from the inner ring of the sponge 452 to the collecting chamber, and the rubbing rod 4551 is horizontally fixed on the extension ring, and the second gear 4553 is rotatably set on one side of the second gear ring 4552, and the second gear 4553 and the second gear ring 4552 are meshed with each other, and a second rotation driver 4554 is set at the end of the second gear 4553, and the second rotation driver 4554 is used to drive the second gear 4553 to rotate. The second rotation driver 4554 is preferably a servo motor, so that the rubbing rod 4551 can rotate around the axis of the sponge 452.

[0047] Reference Fig. 9 An air inlet pipe 46 is connected to the input end of the fan 44 , and a one-way valve 47 is provided on one end of the air inlet pipe 46 away from the fan 44 , so that external air can enter the air inlet pipe 46 through the one-way valve 47 .

[0048] This can prevent the air in the cleaning chamber 41 from flowing back to the outside through the fan 44 .

[0049] Reference Figure 1 and Figure 2 A base 5 is provided at the bottom of the false twist roller 1 , and a gap exists between the base 5 and the lifting frame 4 in the vertical direction. A corrugated sleeve 51 is provided in the gap along the vertical direction, and the corrugated sleeve 51 surrounds the three false twist rollers 1 .

[0050] If the corrugated sleeve 51 is not provided, part of the fluff will be discharged and fly. However, after the corrugated sleeve 51 is provided, the situation that part of the fluff flies when the cleaning brush 3 cleans the end surface of the false twist wheel 11 can be avoided.

[0051] Reference Figure 2 and Fig. 9A lifting unit 6 for driving the lifting frame 4 to move in a vertical direction is arranged on the lifting frame 4. The lifting unit 6 includes a threaded rod 61. The threaded rod 61 penetrates the lifting frame 4 in a vertical direction and is threadedly matched with the lifting frame 4. A guide rod 63 is arranged in parallel on one side of the threaded rod 61. The guide rod 63 penetrates the lifting frame 4 in a vertical direction and is slidably matched with the lifting frame 4. A third rotation driver 62 for driving the threaded rod 61 to rotate is arranged at the end of the threaded rod 61.

[0052] The third rotary driver 62 is preferably a servo motor. When the lifting frame 4 needs to be lifted or lowered, the third rotary driver 62 drives the threaded rod 61 to rotate the lifting frame 4, so that the lifting frame 4 can be lifted or lowered in the vertical direction.

[0053] Reference Figure 1-Figure 11 The present invention also relates to a spinning process of composite fibers, which uses a fiber false twist spinning device, and the specific steps are as follows:

[0054] S1, the lifting frame 4 rises to the highest position, the cleaning brush 3 on the lifting frame 4 extends horizontally and contacts the end face of the false twist wheel 11 located at the highest position, the cleaning brush 3 rotates around its own axis, the false twist wheel 11 rotates around the axis of the false twist roller 1, and after the false twist wheel 11 rotates one circle, the cleaning brush 3 completely sweeps the end face of the false twist wheel 11, and the cleaning brush 3 generates static electricity when rotating and generates adsorption force on the fluff, and the cleaning brush 3 retracts into the cleaning chamber 41 after rotating for the rated rotation time.

[0055] S2. A high-speed airflow is generated in the cleaning chamber 41 to blow out the fluff attached to the cleaning brush 3. At the same time, the lifting frame 4 descends. The height to which the lifting frame 4 descends is the same as the sum of the thickness of the false twist roller 1 and the diameter of the fiber rope 2. Subsequently, the cleaning brush 3 corresponding to the false twist wheel 11 at the same height as the lifting frame 4 extends out and rotates. During the descent of the lifting frame 4, the cleaning brush 3 on the lifting frame 4 that can contact the end surface of the false twist wheel 11 after being extended needs to be extended until the lifting frame 4 descends to the lowest position. After the cleaning brush 3 cleans the lower end surface of the false twist wheel 11 located at the lowermost side, the cleaning is completed.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
