Description
Technical Field
[0001] This application relates to the field of drawing frame technology, and in particular to an anti-clogging device for drawing frames. Background Technology
[0002] As a key piece of equipment in textile production, the drawing frame's main function is to improve the internal structure of the sliver, enhance the uniformity of long segments, reduce weight unevenness, straighten and parallel fibers and reduce hooks, while ensuring that different raw materials are mixed evenly according to the specified mixing ratio and that the fineness meets the requirements.
[0003] In existing technology, during the drawing frame process of multiple fiber slivers, as the fiber slivers enter the drawing frame through the inlet, they are prone to adhering to and carrying lint, short fibers, and other impurities. These lint, short fibers, and other impurities often accumulate at the inlet of the drawing frame (such as the trumpet or condenser), forming "cotton mice" or fiber clumps. The continuous accumulation of impurities can easily cause blockage of the drawing frame, making it impossible to guarantee the stable and efficient operation of the drawing frame. Once a blockage occurs, the machine must be stopped, and the blockage must be cleared by staff before the drawing frame can be used again.
[0004] Therefore, we propose an anti-clogging device for drawing frames to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide an anti-clogging device for a drawing frame, which can comprehensively and efficiently remove short fibers, lint, and other debris from the surface of the fiber sliver, preventing debris from accumulating and clogging at the inlet of the drawing frame, making it less likely for debris to enter the drawing frame, thereby ensuring the smooth flow of the fiber sliver conveying channel at the inlet of the drawing frame and ensuring the stable and efficient operation of the drawing frame.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an anti-clogging device for a drawing frame, comprising a U-shaped frame disposed at the inlet of the drawing frame, wherein two rotating shafts are rotatably mounted inside the U-shaped frame, and each of the two rotating shafts is fixedly fitted with a lint roller sleeve, and felt is detachably fixedly mounted on each of the two lint roller sleeves; a drive assembly is disposed on the front side of the U-shaped frame, the drive assembly being used to control the relative rotation of the two rotating shafts; and two dust suction hoods with open bottoms are fixedly mounted inside the U-shaped frame, the two dust suction hoods being respectively located at... On both sides of the felt, the tops of the two dust hoods are fixedly connected to the same U-shaped dust conveying pipe. The top of the U-shaped dust conveying pipe is fixedly connected to the dust inlet pipe. A dust collection box and an air pump are fixedly installed on the rear outer wall of the U-shaped frame. A dust filter is fixedly installed inside the dust collection box. The end of the dust inlet pipe away from the U-shaped dust conveying pipe is fixedly connected to the top of the dust collection box. An air suction pipe is fixedly installed at the suction end of the air pump. One end of the air suction pipe extends into the dust collection box. The dust filter is located between the air suction pipe and the dust inlet pipe. An exhaust pipe is fixedly installed at the discharge end of the air suction pipe.
[0007] By adopting the above technical solution, the drive component controls the relative rotation of the two rotating shafts, which allows the felt on the lint roller sleeve to effectively adhere to the lint, short fibers and other debris on the surface of the fiber strip at the inlet of the drawing frame, avoiding the accumulation of debris that could cause blockage of the drawing frame. The air pump is used to extract air from the dust collection box, U-shaped dust conveying pipe, dust inlet pipe and two dust suction hoods, creating negative pressure in the dust collection box, U-shaped dust conveying pipe, dust inlet pipe and two dust suction hoods, which can suck the flying fibers, lint and other small debris that are not completely adhered by the felt into the dust collection box during the process of the felt adhering and cleaning the surface of the fiber strip.
[0008] A further feature of this application is that: a male hook and loop fastener and a female hook and loop fastener are fixedly installed at both ends of the felt, and the male hook and loop fastener and the female hook and loop fastener are adhered to each other.
[0009] By adopting the above technical solution, the felt can be easily and quickly disassembled and replaced.
[0010] A further feature of this application is that the sides of the felt and the lint roller sleeve that are close to each other are both frosted surfaces, and the felt and the lint roller sleeve are in frictional contact with each other.
[0011] By adopting the above technical solution, it can be ensured that the felt rotates synchronously with the felt roller sleeve.
[0012] A further configuration of this application is as follows: the drive assembly includes two gears and a motor, the front ends of the two rotating shafts extend outside the U-shaped frame, the two gears are respectively fixedly sleeved on the front ends of the corresponding rotating shafts, the two gears mesh with each other, the motor is located in front of the U-shaped frame, and the output shaft end of the motor is fixedly connected to the front end of one of the rotating shafts.
[0013] By adopting the above technical solution, the motor is used to drive the rotating shaft that is fixedly connected to its output shaft end to rotate. Under the meshing transmission of two gears, the two rotating shafts can be controlled to rotate synchronously relative to each other.
[0014] A further feature of this application is that a base located below the gear is fixedly installed on the front outer wall of the U-shaped frame, and the motor is fixedly installed on the base.
[0015] By adopting the above technical solution, the motor can be stably supported.
[0016] A further feature of this application is that a hollow air distribution plate is fixedly installed on the bottom inner wall of the U-shaped frame, and an air outlet is fixedly connected to the top of the hollow air distribution plate, with the end of the exhaust pipe away from the air pump extending into the hollow air distribution plate.
[0017] By adopting the above technical solution, the clean gas discharged by the air pump is introduced into the hollow air distribution plate through the exhaust pipe, so that the air is blown upward through the air outlet. This can form a stable airflow in the fiber strip conveying area, which can help blow away the lint, short fibers and other debris adhering to the surface of the fiber strip, allowing the lint, short fibers and other debris to enter the two dust hoods more smoothly and be sucked away, further improving the cleaning effect on the surface of the fiber strip.
[0018] A further feature of this application is that the number of air outlets is set to multiple, and the multiple air outlets are distributed in an array.
[0019] By adopting the above technical solution, the range and uniformity of the blown airflow are improved, ensuring that lint, short fibers and other debris adhering to the surface of the fiber strip are more comprehensively sucked into the two dust collection hoods.
[0020] A further feature of this application is that a plurality of fiber strip guide rollers are rotatably mounted inside the U-shaped frame, and the plurality of fiber strip guide rollers are evenly distributed in two rows.
[0021] The above technical solution is used to smoothly guide the fiber sliver into the drawing frame.
[0022] A further feature of this application is that a support frame is fixedly installed at the bottom of the U-shaped frame, and the support frame has a plurality of evenly distributed assembly holes.
[0023] By adopting the above technical solution, the support frame can be firmly installed at a suitable position at the inlet of the drawing frame using bolts, so that the U-shaped frame is aligned with the inlet of the drawing frame.

[0025] By adopting the above technical solution, it is convenient for staff to regularly open the sealing cover and clean the debris collected in the dust collection box.
[0026] This application includes at least one of the following beneficial technical effects:
[0027] 1. This application utilizes a drive assembly to control the relative rotation of two rotating shafts. The lint roller sleeve and felt on the rotating shafts rotate accordingly, so that the felt on the lint roller sleeve can effectively adhere to the lint, short fibers and other impurities on the surface of the fiber sliver at the inlet of the drawing frame.
[0028] 2. This application utilizes a dust collection system consisting of two dust hoods, a U-shaped dust conveying pipe, a dust inlet pipe, a dust collection box, a dust filter, and an air pump. This system can suck up the flying fibers, lint, and small debris that are not completely adhered to the felt during the process of cleaning the surface of the fiber strip with felt adhesion into the dust collection box. This further reduces the risk of debris accumulating and clogging at the inlet of the drawing frame, significantly improving the anti-clogging effect. Thus, the adhesion of the felt combined with the negative pressure dust collection creates a dual protection mechanism, which can comprehensively and efficiently clean the surface of the fiber strip, such as short fibers and lint, preventing debris from accumulating and clogging at the inlet of the drawing frame. This makes it more difficult for debris to enter the drawing frame, thereby ensuring the smooth flow of the fiber strip conveying channel at the inlet of the drawing frame and ensuring the stable and efficient operation of the drawing frame.
[0029] 3. This application utilizes the clean air discharged from the exhaust pipe to be introduced into the hollow air distribution plate, and then blown upward from multiple air outlets arranged in an array. This creates a stable airflow in the fiber strip conveying area. This airflow can help blow away residual lint, short fibers and other debris on the surface of the fiber strip, making it easier for the dust collection hood to suck it in, effectively preventing fiber accumulation, further improving the cleaning effect on the surface of the fiber strip, and further reducing the risk of clogging.
[0030] 4. The felt in this application is fixed to the lint roller sleeve by the mutual adhesion of the male and female hook and loop fasteners. When the felt has been used for a period of time and too much debris adheres to it, affecting the cleaning effect, the felt can be quickly and easily disassembled and replaced without complicated tools and operating procedures, saving maintenance time and labor costs, while also reducing equipment downtime and improving production efficiency.

[0037] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0038] See Figures 1-5 This application provides an anti-clogging device for a drawing frame, including a U-shaped frame 1 installed at the inlet of the drawing frame. Two rotating shafts 2 are rotatably mounted inside the U-shaped frame 1. Each rotating shaft 2 is fixedly fitted with a lint roller sleeve 3, and felt 20 is detachably mounted on each of the two lint roller sleeves 3. A drive assembly is provided on the front side of the U-shaped frame 1 to control the relative rotation of the two rotating shafts 2. By controlling the relative rotation of the two rotating shafts 2, the felt 20 on the lint roller sleeves 3 can effectively adhere to lint, short fibers, and other debris on the surface of the fiber sliver at the inlet of the drawing frame, preventing debris accumulation and blockage of the drawing frame, ensuring smooth fiber sliver conveying channel at the inlet of the drawing frame, and ensuring stable and efficient operation of the drawing frame. Two dust suction hoods 7 with open bottoms are fixedly installed inside the U-shaped frame 1. The two dust suction hoods 7 are located on the left and right sides of the felt 20, respectively. The tops of the two dust suction hoods 7 are fixedly connected to the same U-shaped dust conveying pipe 8, and the top of the U-shaped dust conveying pipe 8 is fixedly connected to... A dust collection box 10 and an air pump 12 are fixedly installed on the rear outer wall of the dust inlet pipe 9 and the U-shaped frame 1. A dust filter 11 is fixedly installed inside the dust collection box 10. The end of the dust inlet pipe 9 away from the U-shaped dust conveying pipe 8 is fixedly connected to the top of the dust collection box 10. An air suction pipe 13 is fixedly installed at the suction end of the air pump 12. One end of the air suction pipe 13 extends into the dust collection box 10. The dust filter 11 is located between the air suction pipe 13 and the dust inlet pipe 9. An exhaust pipe 14 is fixedly installed at the discharge end of the air suction pipe 13. The dust collection system, consisting of two dust hoods 7, a U-shaped dust conveying pipe 8, a dust inlet pipe 9, a dust collection box 10, a dust filter 11, and an air pump 12, forms a double protection with the mechanical cleaning of the felt 20. The dust collection system can suck the flying fibers, lint, and small debris that are not completely adhered to by the felt 20 into the dust collection box 10 during the process of the felt 20 adhering to and cleaning the surface of the fiber strip, further reducing the risk of debris accumulating and clogging at the inlet of the drawing frame, and significantly improving the anti-clogging effect.
[0039] In this embodiment, the two ends of the felt 20 are respectively fixedly installed with a male hook and loop fastener 201 and a female hook and loop fastener 202. The male hook and loop fastener 201 and the female hook and loop fastener 202 are glued to each other. The felt 20 is detachably installed on the lint roller sleeve 3 by means of the male hook and loop fastener 201 and the female hook and loop fastener 202 being glued to each other. When the felt 20 is used for a period of time and too much debris adheres to it, affecting the cleaning effect, it can be quickly and easily disassembled and replaced without complicated tools and operating procedures, saving maintenance time and labor costs, while also reducing equipment downtime and improving production efficiency.
[0040] In this embodiment, the sides of the felt 20 and the lint roller sleeve 3 that are close to each other are both made of frosted material. The frictional contact between the felt 20 and the lint roller sleeve 3 ensures that the felt 20 rotates synchronously with the lint roller sleeve 3.
[0041] In this embodiment, the drive assembly includes two gears 4 and a motor 5. The front ends of the two rotating shafts 2 extend outside the U-shaped frame 1. The two gears 4 are respectively fixedly sleeved on the front ends of the corresponding rotating shafts 2 and mesh with each other. The motor 5 is located in front of the U-shaped frame 1. The output shaft end of the motor 5 is fixedly connected to the front end of one of the rotating shafts 2. The motor 5 is used to drive the rotating shaft 2 fixedly connected to its output shaft end to rotate. Under the meshing transmission action of the two gears 4, the two rotating shafts 2 can be controlled to rotate synchronously relative to each other.
[0042] In this embodiment, a base 6 located below the gear 4 is fixedly installed on the front outer wall of the U-shaped frame 1, and the motor 5 is fixedly installed on the base 6. The base 6 provides stable support for the motor 5.
[0043] In this embodiment, a hollow air distribution plate 15 is fixedly installed on the bottom inner wall of the U-shaped frame 1. An air outlet 16 is fixedly connected to the top of the hollow air distribution plate 15. The end of the exhaust pipe 14 away from the air pump 12 extends into the hollow air distribution plate 15. The number of air outlets 16 is set to multiple, and the multiple air outlets 16 are arranged in an array. The exhaust pipe 14 guides the clean gas discharged by the air pump 12 into the hollow air distribution plate 15, so that the air is blown upward through the multiple arrayed air outlets 16. A stable airflow can be formed in the fiber strip conveying area, which can help blow away the lint, short fibers and other debris adhering to the surface of the fiber strip, allowing the lint, short fibers and other debris to enter the two dust hoods 7 more smoothly and be sucked away, further improving the cleaning effect on the surface of the fiber strip.
[0044] In this embodiment, multiple fiber sliver guide rollers 17 are rotatably installed inside the U-shaped frame 1. The multiple fiber sliver guide rollers 17 are evenly distributed in two rows, which can smoothly guide the fiber sliver into the drawing frame.
[0045] In this embodiment, a support frame 18 is fixedly installed at the bottom of the U-shaped frame 1. The support frame 18 has multiple evenly distributed assembly holes. The support frame 18 can be firmly installed at a suitable position at the inlet of the drawing frame by bolts, so that the U-shaped frame 1 is aligned with the inlet of the drawing frame.
[0046] In this embodiment, a cleaning hole is provided on the rear side wall of the dust collection box 10, and a sealing cover 19 is fixedly installed on the rear side wall of the dust collection box 10 by screws, so that the staff can open the sealing cover 19 regularly to clean the debris collected in the dust collection box 10.
[0047] In this embodiment, it should be noted that both the motor 5 and the air pump 12 are commercially available, and their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described in detail here.
[0048] With the above structure, when using the anti-clogging device for the drawing frame provided in this application, the support frame 18 is securely installed and fixed at a suitable position at the inlet of the drawing frame using bolts, so that the U-shaped frame 1 is aligned with the inlet of the drawing frame, and multiple fiber strips are evenly arranged so that one end of each fiber strip passes between the two rows of fiber strip guide rollers 17 and enters from the inlet of the drawing frame. At this time, the fiber strips also pass between the two felts 20, and the fiber strips are in contact with the surfaces of the two felts 20. By controlling the operation of the drawing frame, multiple fiber strips are continuously entered. At this time, the motor 5 is turned on and its output shaft drives the fixed connection thereto. The rotating shaft 2 rotates, and through the transmission of two meshing gears 4, the two rotating shafts 2 rotate synchronously relative to each other. The rotating shaft 2 drives the lint roller sleeve 3 to rotate. Since the lint roller sleeve 3 and the felt 20 are rubbed together by the abrasive surface, and the male Velcro 201 and female Velcro 202 at both ends of the felt 20 are glued and fixed, the felt 20 rotates synchronously with the lint roller sleeve 3. During the process of the fiber strip entering the drawing frame through the U-shaped frame 1, the rotating felt 20 uses its own adhesiveness to adhere and clean the lint, short fibers and other debris on the surface of the fiber strip, reducing the possibility of debris accumulating at the inlet of the drawing frame from the source.
[0049] Simultaneously, the air pump 12 is activated, generating suction that draws air from the dust collection box 10 through the suction pipe 13. This creates negative pressure within the dust collection box 10, the U-shaped dust conveying pipe 8, the dust inlet pipe 9, and the two dust hoods 7. The dust hoods 7, located on the left and right sides of the felt 20 with openings at the bottom, suck in the flying fibers, lint, and small debris not completely adhered to the felt 20 generated during the cleaning process. These debris then sequentially enter the dust collection box 10 through the dust hoods 7, the U-shaped dust conveying pipe 8, and the dust inlet pipe 9. The dust filter 11 inside the dust box 10 filters the intake air, trapping fiber debris, while the clean air is discharged through the exhaust pipe 14. Thus, the adhesion of the felt 20 combined with the negative pressure suction creates a dual protection mechanism, which can comprehensively and efficiently clean short fibers, lint, and other debris from the surface of the fiber strip, preventing debris from accumulating and clogging at the draw frame inlet. This makes it less likely for debris to enter the draw frame, ensuring the smooth flow of the fiber strip conveying channel at the draw frame inlet and ensuring the stable and efficient operation of the draw frame.
[0050] The clean gas discharged by the air pump 12 is introduced into the hollow air distribution plate 15 through the exhaust pipe 14. The air entering the hollow air distribution plate 15 is blown upward from multiple arrayed air outlets 16, forming a stable airflow in the fiber strip conveying area. This airflow can help blow away residual lint, short fibers and other debris on the surface of the fiber strip, making it easier for it to be sucked in by the dust hood 7, effectively preventing fiber accumulation, further improving the cleaning effect on the surface of the fiber strip, and further reducing the risk of clogging.
[0051] When too much debris adheres to the surface of the felt 20, affecting the cleaning effect, the staff can directly separate the female hook and loop fastener 201 and the female hook and loop fastener 202 to quickly disassemble and replace the felt 20. No complicated tools or operating procedures are required, saving maintenance time and labor costs, while also reducing equipment downtime and improving production efficiency.
