Description

Technical Field

[0001] This invention relates to the field of spinning machine technology, specifically to a segmented carding and anti-tangle spinning machine for spinning production. Background Technology

[0002] In the textile machinery field, free-end spinning technology (such as friction air-jet spinning and rotor spinning) has been widely used in cotton spinning, wool spinning, and short chemical fiber processing due to its advantages such as short process, high output, and large package size. Traditional spinning machines typically consist of a feeding and drafting mechanism, a carding and output mechanism, a cohesion and twisting mechanism, and an output winding mechanism. However, existing spinning machines, especially when processing fiber materials such as recycled fibers, low-grade raw cotton, or chemical fiber raw materials with poor length uniformity, suffer from the following technical challenges: Most existing equipment uses a single carding roller structure. The surface of this carding roller is usually covered with a single type of needle tooth, resulting in a relatively coarse carding effect on the fibers. Since the fiber only undergoes one carding process from feeding to output, it often leads to insufficient fiber carding, low degree of single-fiber formation, or excessive damage to long fibers, affecting yarn strength. Although some existing technologies reduce fiber entanglement on the rollers by installing anti-winding friction plates at the lower roller in the feeding and drafting zone... However, during the fiber conveying process from the combing roller to the cohesion and twisting zone, due to airflow disturbance and static electricity, the fiber flow is prone to entanglement or snagging on the inner wall of the conveying channel, the cotton outlet of the combing chamber, and near the cotton stripping point, forming "cotton knots" or "mouse hairs," which seriously affects the continuity of spinning and the quality of yarn. As the textile industry develops towards multi-variety and small-batch production, the existing equipment has poor adaptability to fibers with different physical properties (such as length, fineness, and moisture regain) and lacks flexible control methods, resulting in an increased breakage rate and decreased production efficiency when spinning special yarns.

[0003] CN116607239B A spinning machine and an anti-tangle device for the spinning machine, wherein multiple partition plates inside the yarn separator are rotatably connected to sliding shafts in pairs, so that each yarn corresponds to each sliding shaft. The yarn contacts the sliding shaft, and the rotation of the sliding shaft drives the yarn to move. Each yarn inlet groove and yarn inlet ring is inserted into each yarn, so that each yarn can be fed individually, preventing the yarn from being lost due to tangling during the feeding process. Summary of the Invention

[0004] To solve the entanglement problem caused by static electricity and incomplete raw material refinement in the prior art, the present invention provides the following technical solution: a segmented carding anti-entanglement spinning machine for spinning production, comprising: a fixed base, wherein the fixed base is configured as a hollow shell, and a carding device is fixedly connected to the inner wall side of the fixed base; The discharge pipe is a conical hollow tube. The side of the discharge pipe is connected to the side of the combing device. The side of the combing device is connected to the feed pipe. The top of the combing device is connected to the air inlet device. The top of the air inlet device is fixedly connected to the winding assembly. The combing device includes a feeding pool, the bottom of which is connected to a first conveying pipe, the bottom of which is connected to a mixing pool, the top of which is connected to a second conveying pipe on one side of the first conveying pipe, the top of which is connected to a discharge pool, a crushing wheel rotatably connected to the inner wall of the feeding pool, the side of the feeding pool being fixedly connected to the inner wall of the fixed base, and the top of the feeding pool being connected to the bottom of the air inlet device.

[0005] Preferably, the crushing wheel includes a crushing rotor, the side of which is provided with an arc-shaped rotating hole, a shredding groove is provided on one side of the arc-shaped rotating hole, and a pneumatic groove is provided on one side of the shredding groove. The crushing rotor is rotatably connected to the inner wall of the feeding pool through the arc-shaped rotating hole, and a boss adapted to the arc-shaped rotating hole is fixedly connected to the side of the inner wall of the feeding pool.

[0006] The cotton sliver raw material is introduced through the feed pipe. Multiple sets of air intake devices are activated. The air intake devices blow airflow by eccentrically placing the carding device. The cotton sliver is introduced into the carding device through the feed pipe. The fixed base supports the equipment. The raw material is crushed inside the feed pipe and driven into the carding device. After multi-stage crushing and conveying, it enters the discharge pipe. It is pulled out by the guide bar and wound by the winding assembly, thus the cotton thread is spun into yarn.

[0007] The raw materials are crushed through the feed pipe under the action of gravity. The fibers are pneumatically combed inside the feed tank and enter the mixing tank through the first conveying pipe with the air flow. Inside the mixing tank, the air is accelerated by the air supply from multiple sets of air intake devices. The crushing wheel rotates under the blowing of air. The arc-shaped rotating hole makes point contact between the crushing wheel and the inner side of the feed tank, which helps to reduce the resistance when the crushing wheel rotates.

[0008] The fibers enter the second conveying pipe through the mixing tank, and are then wound around the fibers inside the discharge tank by the rotation and stirring of the crushing wheel.

[0009] The fibers are discharged through the inner wall of the discharge pipe, and then wound around the fibers by the rotation of the crushing wheel. The setting of the shredding groove facilitates pneumatic drive in the face of wind. The setting of the pneumatic groove facilitates the shredding of fibers when the crushing wheel rotates, thereby reducing the risk of entanglement. The setting of the pneumatic groove also facilitates the pushing and guiding of fibers, so that the fibers can be rotated and wound into a line for discharge.

[0010] Preferably, the air inlet device includes an air guide duct, an air guide block is fixedly connected to the bottom of the inner wall of the air guide duct, a fixed end of a first motor is fixedly connected to the top of the air guide duct via a bracket, a conical filter tube is rotatably connected to the side of the fixed end of the first motor, a guide fan is fixedly connected to the drive shaft of the first motor, a water inlet pipe is connected to the side of the air guide duct, the bottom of the conical filter tube is rotatably connected to the top of the air guide duct, and the bottom of the air guide duct is located at the top side of the feed tank.

[0011] Preferably, the fan includes a rotating shaft, a dispersing blade is fixedly connected to the side of the rotating shaft, and a guide blade is fixedly connected to the side of the rotating shaft above the dispersing blade.

[0012] The top of the rotating shaft is fixedly connected to the drive shaft of the first motor. The scattering blades are located on one side of the water inlet pipe. During the fiber introduction process, the first motor is started, and the drive shaft of the first motor rotates to drive the guide fan. The rotation of the guide fan drives the air to enter the interior of the guide pipe through the filter of the conical filter tube.

[0013] Air is pressurized inside the air duct and then guided through the air guide block into the feed tank, driving the crushing wheel with air. The water inlet pipe is connected to an external water source to introduce a small amount of water. By controlling the moisture content of the fiber within a certain range, the static electricity inside the fiber is gathered. The water drips onto the surface of the dispersing blades and is dispersed. Under the air push of the air guide blades, the water flows. The drive shaft of the first motor drives the rotating shaft to rotate.

[0014] Air mixed with trace amounts of water mist combines with the fibers. When the water content inside the fibers rises to between 6% and 9%, the introduction of water eliminates static electricity and reduces the risk of entanglement. At the same time, the trace amounts of water mist do not cause the risk of dampness. The air guide block is set to gather air on the side of the pneumatic trough. The air is guided by an eccentric method to drive the crushing wheel to rotate, thereby crushing and conveying the fibers inside the feed tank. At the same time, static electricity is eliminated. The conical filter tube is set to facilitate external cleaning, thereby facilitating continuous air guidance and reducing the possibility of fiber entanglement.

[0015] Preferably, the feed tube includes a U-shaped tube, a feed plate is sleeved and fixedly connected to the top of the U-shaped tube, a fixed end of a second motor is fixedly connected to the side of the U-shaped tube, a transmission assembly is fixedly connected to the drive shaft of the second motor, a shredding roller is fixedly connected to the side of the transmission assembly, a fracture groove is opened on the side of the shredding roller, the top of the feed plate communicates with the side of the feed pool, and the side of the U-shaped tube is fixedly connected to the side of the fixed base.

[0016] Preferably, the transmission assembly includes a drive gear, a driven gear meshing with the side of the drive gear, and a first belt assembly sleeved on the side of the drive gear, the side of the first belt assembly being fixedly connected to the side of the shredding roller.

[0017] The side of the drive gear is fixedly connected to the drive shaft of the second motor. The raw material is introduced through the top of the return tube. The second motor is started, and the drive shaft of the second motor rotates, which drives the transmission assembly to rotate. The rotation of the transmission assembly drives the shredding roller to rotate, and the rotation of the shredding roller drives the fracture groove to rotate.

[0018] The shredding roller rotates to crush and refine the raw material, which is then conveyed through the return tube along the top of the feed plate. The return tube is designed to allow the fibers to accumulate inside and then descend under gravity. The drive shaft of the second motor rotates, which in turn drives the drive gear to rotate.

[0019] The rotation of the drive gear drives the rotation of the driven gear. The shredding rollers fixed to the sides of the drive and driven gears shred the raw materials by rotating at different speeds. The shredding rollers on the side of the first belt assembly facilitate the conveying of the raw materials by the driven and drive gears, thereby shredding and refining the raw materials for output, thus reducing the possibility of fiber entanglement.

[0020] Preferably, the winding assembly includes a fixing frame, a second belt assembly is rotatably connected to the top of the inner wall of the fixing frame, and a fixing spring is fixedly connected to the top of the second belt assembly.

[0021] A brake strip is fixedly connected to the side of the fixing spring. The bottom of the second belt assembly is fixedly connected to the top of the first motor. When the second belt assembly is started, the rotation of the second belt assembly drives the fixing spring to rotate. The winding drum is fixed by the elasticity of the fixing spring. The brake strip reduces the possibility of the winding drum coming off. The rotation of the second belt assembly drives the first motor to rotate. The rotation of the first motor throws off the impurities on the surface, thereby facilitating the continuous input of air.

[0022] The beneficial effects of the technical solution provided by this invention include: 1. After the cotton sliver raw material is introduced through the feed pipe, multiple sets of air intake devices are activated, and the fibers are dispersed inside the carding device through an eccentrically arranged airflow. After entering the carding device, the cotton sliver undergoes multi-stage crushing and conveying inside, and finally enters the discharge pipe, where it is pulled out by guide bars and wound into yarn by the winding assembly. The raw material is crushed in the feed pipe under the action of gravity, and the fibers are carded by the airflow in the feed pool. With the airflow, they enter the mixing pool through the first conveying pipe, where they are accelerated by the airflow provided by multiple sets of air intake devices. The crushing wheel rotates continuously under the push of the airflow, and the arc-shaped rotating hole keeps the crushing wheel in point contact with the inner side of the feed pool, reducing resistance during rotation. The fibers enter the second conveying pipe through the mixing pool, and are wound in the discharge pool by the rotation and stirring of the crushing wheel. They are then discharged along the inner wall of the discharge pipe, and the rotation of the crushing wheel makes the fibers uniformly yarn. The shredding trough is driven by the airflow on the windward side. The pneumatic trough assists in tearing the fibers when the crushing wheel rotates, reducing entanglement, and at the same time promotes the directional movement of the fibers, which is convenient for them to be discharged after being rotated into yarn.

[0023] 2. During fiber introduction, after the first motor starts, the drive shaft drives the guide fan to rotate. Air is filtered through the conical filter tube and enters the guide duct. After being pressurized in the guide duct, it is sent into the feed tank through the guide block, driving the crushing wheel to rotate. An external water source is introduced through the water inlet pipe to control the fiber moisture content within a suitable range, allowing internal static electricity to accumulate. Water droplets are dispersed after falling onto the surface of the dispersing blades and diffused under the airflow of the guide blades. The drive shaft of the first motor drives the rotating shaft to rotate, allowing the air, trace water mist, and fiber to mix thoroughly. When the fiber moisture content increases to 6% to 9%, static adsorption is eliminated, reducing the risk of entanglement, while the trace water mist does not cause dampness. The guide block concentrates the air and directs it to the side of the pneumatic trough. The eccentric airflow drives the crushing wheel to rotate, allowing the fiber to be crushed and conveyed in the feed tank, with static electricity eliminated simultaneously. The conical filter tube facilitates external cleaning, ensures continuous and stable air guidance, and reduces the possibility of fiber entanglement.

[0024] 3. Raw materials are introduced from the top of the U-shaped tube. After the second motor starts, the drive shaft drives the transmission assembly to rotate, and the shredding rollers rotate accordingly. The breaking grooves pulverize and refine the raw materials during rotation. After being conveyed through the U-shaped tube, the raw materials are output along the top of the feed plate. The U-shaped structure causes the fibers to accumulate inside the tube and then settle under gravity. The drive shaft of the second motor drives the drive gear to rotate, which in turn drives the driven gear. The shredding rollers fixed on both sides shred the raw materials at different speeds. The shredding rollers on the side of the first belt assembly assist in the conveying, ensuring that the raw materials are evenly shredded and refined before output, reducing the possibility of fiber entanglement.

[0025] 4. After the second belt assembly starts, it drives the fixed spring to rotate. The winding drum is elastically fixed by the spring, and the brake strip prevents the winding drum from loosening. The rotation of the second belt assembly drives the first motor to rotate. During rotation, the first motor throws away surface impurities, ensuring a continuous air input. Attached Figure Description

Detailed Implementation

[0028] Example 1, please refer to Figures 1-3This invention provides a technical solution: a segmented carding anti-tangle spinning machine for yarn production. The cotton sliver raw material is introduced through the feed pipe 3. Multiple sets of air inlet devices 5 are activated. The air inlet devices 5 blow airflow through the eccentric placement of the carding device 2. The cotton sliver is introduced into the carding device 2 through the feed pipe 3. The fixed base 1 supports the equipment. The raw material is crushed inside the feed pipe 3 and driven into the carding device 2. After multi-stage crushing and conveying, it enters the discharge pipe 4. Guided by guide bars, it is pulled out and wound by the winding assembly 6, thus enabling the cotton yarn to be spun. The raw material is crushed through the feed pipe 3 under gravity. The fibers undergo pneumatic carding inside the feed tank 201 and enter the mixing tank 203 through the first conveying pipe 202 with the airflow. Inside the mixing tank 203, it is further processed by multiple sets of air inlet devices... The airflow supply from position 5 accelerates the crushing wheel 206, which rotates under the blowing of air. The arc-shaped rotating hole 2062 makes point contact between the crushing wheel 2061 and the inner side of the feed tank 201, thereby reducing the resistance when the crushing wheel 2061 rotates. The fiber enters the second conveying pipe 204 through the mixing tank 203. The fiber is wrapped in the discharge tank 205 by the rotation and stirring of the crushing wheel 2061 and is discharged through the inner wall of the discharge pipe 4. The fiber is wrapped by the rotation of the crushing wheel 2061. The shredding groove 2063 is set to facilitate pneumatic drive in the face of wind. The pneumatic groove 2064 is set to shred the fiber when the crushing wheel 2061 rotates, thereby reducing the risk of entanglement. The pneumatic groove 2064 is set to push and guide the fiber, so that the fiber can rotate and be wrapped into a thread for discharge.

[0029] Example 2, please refer to Figures 1-5Based on the first embodiment, during the fiber introduction process, the first motor 503 is started. The drive shaft of the first motor 503 rotates, driving the guide fan 505. The rotation of the guide fan 505 drives air through the conical filter tube 504 and into the interior of the air guide tube 501. The air is pressurized inside the air guide tube 501 and is led out through the air guide block 502 into the interior of the feed tank 201, driving the crushing wheel 2061 with air. The water inlet pipe 506 is connected to an external water source to introduce a small amount of water. By controlling the moisture content of the fiber within a certain range, the static electricity inside the fiber is gathered. The water drips onto the surface of the dispersing blades 5052 and is dispersed. Under the air push of the guide blades 5053, the water flows out. The first motor 503 drives the rotating shaft 5051 to rotate. Air mixed with a trace amount of water mist combines with the fiber. When the water content inside the fiber rises to between 6% and 9%, the introduction of water eliminates the adsorption between static electricity, reducing the risk of entanglement. At the same time, the trace amount of water mist does not cause the risk of dampness. The air guide block 502 is set to gather air on the side of the pneumatic groove 2064. The air is driven to rotate the crushing wheel 2061 by eccentric air guidance, so that the fiber is crushed and conveyed inside the feed pool 201. At the same time, static electricity is eliminated. The conical filter tube 504 is set to facilitate cleaning from the outside, thereby facilitating continuous air guidance and reducing the possibility of fiber entanglement.

[0030] Example 3, please refer to Figures 1-7 Based on the second embodiment, the raw material is introduced through the top of the return tube 301. The second motor 303 is started, and the drive shaft of the second motor 303 rotates, driving the transmission assembly 304 to rotate. The rotation of the transmission assembly 304 drives the shredding roller 305 to rotate, and the rotation of the shredding roller 305 drives the breaking groove 306 to rotate. The rotation of the shredding roller 305 drives the raw material to be crushed and refined. After being conveyed by the return tube 301, it is output along the top of the feed plate 302. The return tube 301 is designed to facilitate the collection of fibers inside the return tube 301. After aggregation, the material descends under the influence of gravity. The drive shaft of the second motor 303 rotates, driving the drive gear 3041 to rotate. The rotation of the drive gear 3041 drives the driven gear 3042 to rotate. The shredding rollers 305 fixed to the sides of the drive gear 3041 and the driven gear 3042 shred the raw material through variable speed rotation. The shredding rollers 305 on the side of the first belt assembly 3043 facilitate the conveying of the raw material by the driven gear 3042 and the drive gear 3041, thereby shredding and refining the raw material for output, thus reducing the possibility of fiber entanglement.

[0031] Example 4, please refer to Figures 1-8Based on the third embodiment, the fixing frame 601 supports the second belt assembly 602. When the second belt assembly 602 is started, its rotation drives the fixing spring 603 to rotate. The winding drum is fixed by the elasticity of the fixing spring 603. The brake strip 604 reduces the possibility of the winding drum coming off. The rotation of the second belt assembly 602 drives the first motor 503 to rotate. The rotation of the first motor 503 throws away impurities on the surface, thereby facilitating continuous air input.
