[0001] The invention relates to the technical field of winding, and in particular to a wool yarn processing fiber pulling and cutting device and a use method thereof. Background Art

[0002] Wool yarn is mainly used for hand knitting and weaving. Wool yarn is a single yarn with twist spun from wool as raw material; wool yarn, also known as wool yarn, is a strand of yarn spun from wool as raw material. At present, with the booming development of the textile industry, wool yarn processing, as a key link, has extremely strict requirements on product quality and production efficiency. The traditional wool yarn processing fiber winding and cutting device has gradually exposed a series of significant problems, making it difficult to adapt to the rhythm of modern large-scale production.

[0003] Traditional pulling and cutting devices have a low degree of automation, and the connection between various processes often relies on manual operation. For example, manual operation in the loading and unloading of wire coils and the pulling and positioning of fibers is not only labor-intensive, but also prone to human errors, resulting in interruptions in the production process or damage to product quality. With the continuous increase in labor costs and the continuous improvement of market requirements for wool yarn product quality and production efficiency, these disadvantages of traditional devices have become increasingly prominent, becoming a bottleneck restricting the further development of the wool yarn processing industry.

[0004] However, during the winding and changing process of the wire reel, the existing pulling and cutting device will cause the fibers to be cut off and, due to their elasticity, will be unable to be wound around the wire reel, resulting in failure to complete the automatic reel changing process. Therefore, the present invention provides a wool yarn processing fiber pulling and cutting device and a method for using the same. Summary of the invention

Under the elasticity of the torsion spring, the rectangular column abuts against the end of the air expansion shaft, and the movable column is pushed out of the base through the linear module, so that the rectangular column moves and pushes the wire roll on the air expansion shaft to unload the material.

[0014] A method for using a wool yarn processing fiber pulling and cutting device, the specific operation is as follows: S1. First, the turntable rotates to move the air expansion shaft to the bottom of the L-shaped support beam, and the electric cylinder pushes the fixed seat to move, so that the clamping shaft is docked with the air expansion shaft, and the clamping shaft contacts the wire roll on the air expansion shaft, and the fiber is placed on the wire roll close to the clamping shaft through the cloth shaft, and one end of the fiber is clamped on the wire roll through the clamping shaft. Then, the air expansion shaft rotates to wind the fiber on the wire roll, and the cloth shaft drives the fiber to move back and forth. When the air expansion shaft rotates a certain number of times, the clamping shaft is released, and the fixed seat is restored to its original position under the drive of the electric cylinder, so that the clamping shaft is separated from the air expansion shaft; S2. Before the winding of the wire roll on the air expansion shaft is completed, the turntable rotates again to move the next air expansion shaft to the right below the L-shaped support beam, and the rotation speed of the previous air expansion shaft remains unchanged. The fiber moves back and forth on the wire roll of the air expansion shaft and is introduced into the wire roll of the previous air expansion shaft. The electric cylinder pushes again to make the clamping shaft dock with the air expansion shaft. When the air expansion shaft drives the clamping shaft to adjust its position, it stops. When the fiber moves to the wire roll close to the clamping shaft again, the winding is completed. The previous air expansion shaft stops rotating, and the clamping shaft clamps the fiber, while the cutting shaft cuts the fiber. Then the air expansion shaft starts to rotate and wind. S3. During the rotation of the turntable, the unloading shaft is placed on the air expansion shaft of the winding wire coil. The air expansion shaft releases the clamping of the wire coil, and the wire coil on the air expansion shaft is pushed off by the unloading shaft. Then the material is loaded and the wire coil is introduced onto the air expansion shaft again.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) Through a series of automated operations such as the motor driving the turntable to rotate, the air expansion shaft to wind up, the electric cylinder to drive the clamping shaft to move, and the linear module to control the unloading shaft to unload, the reliance on manual operation is reduced, the labor intensity is reduced, the stability and reliability of the production process are improved, and production interruptions or product quality problems caused by human errors are effectively avoided; (2) The special structural design of the clamping shaft, such as the locking structure and the air expansion shaft, realizes linkage.

Combined with the action of the unloading shaft, the automatic reel change process can be completed smoothly, and the fiber winding is guaranteed to be accurate during the reel change process, which greatly improves the production efficiency, reduces the production interruption time, and makes the entire wool yarn processing process smoother and more efficient; (3) The motor of the cloth shaft cooperates with the reciprocating screw to accurately control the density and uniformity of fiber winding; the electromagnet and spring of the cutting shaft control the extension and retraction of the electric heating knife, which can accurately adjust the cutting parameters according to the fiber material and thickness, ensuring the accuracy and stability of the cutting effect, which is conducive to improving the quality consistency of wool yarn products.

DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0019] See also Figure 1 A wool yarn processing fiber pulling and cutting device is mainly composed of a base 1, a pedestal 2, a turntable 3, an air expansion shaft 4, a cutting shaft 5, a cloth shaft 6, an L-shaped support beam 7, a clamping shaft 8, a discharge shaft 9 and related driving and control components.

[0020] The base 1 is the basic supporting structure of the whole device, providing a stable installation platform for other components. The base 2 is installed on the base 1, and a rotatable turntable 3 is installed on its side. The turntable 3 is driven by a special motor to rotate, which can achieve a smooth and precise rotation.

[0021] See also Figure 2The cutting shaft 5 includes a hollow shaft column 51 mounted on the rotating disk 3, and a movable opening 52 is provided at the end of the hollow shaft column 51. Two guide columns 53 are installed inside the hollow shaft column 51 at both ends of the movable opening 52, and a connecting plate 54 that can slide up and down is provided on the guide column 53, and an electric heating knife 55 is installed on the connecting plate 54. A spring 56 is connected to the bottom end of the guide column 53 for resetting the connecting plate 54. An electromagnet 57 is also installed at the bottom end of the hollow shaft column 51.

[0022] When the electromagnet 57 is powered on, the magnetic field generated attracts the connecting plate 54 to move downward, and the electric knife 55 is retracted from the movable opening 52 at this time, so that the fiber can smoothly move back and forth on the hollow shaft column 51 without being cut; when the fiber needs to be cut, the electromagnet 57 is powered off, the connecting plate 54 is reset under the elastic action of the spring 56, and the electric knife 55 extends from the movable opening 52. Since the movable opening 52 is located at the tangent position of the moving track of the hollow shaft column 51, the electric knife 55 can cut the fiber when it moves back and forth on the hollow shaft column 51 and passes through the movable opening 52. In actual production, the heating temperature of the electric knife 55 and the elastic coefficient of the spring 56 can be adjusted according to the material and thickness of the fiber to ensure the accuracy and stability of the cutting effect.

[0023] See also Figure 8 The cloth shaft 6 is composed of a shaft frame 61, a reciprocating screw 62, a reciprocating slider 63 and a limit sleeve 64 installed on the base 2. The motor installed inside the base 2 drives the reciprocating screw 62 to rotate, and the reciprocating slider 63 on the reciprocating screw 62 can perform threaded rotation along the screw. The limit sleeve 64 is installed on the reciprocating slider 63 and is used for pulling the fiber. During the working process, the motor drives the reciprocating screw 62 to rotate, so that the reciprocating slider 63 drives the limit sleeve 64 to move back and forth, and the fiber is evenly wound on the coil. By adjusting the speed of the motor and the pitch of the reciprocating screw 62, the density and uniformity of the fiber during the winding process can be controlled to meet the process requirements of different wool yarn processing.

[0024] See also Figure 3 and Figure 4 The clamping shaft 8 includes a rotatable shaft seat 81 on the fixed seat 10 , a snap-fit ​​structure 82 is installed at the front end of the shaft seat 81 to dock with the gas expansion shaft 4 , and a hydraulic clamp 83 is also provided on the shaft seat 81 .

[0025] The clamping structure 82 is composed of a round shaft 821 mounted on the shaft seat 81 and a sleeve 822 mounted on the front end of the gas expansion shaft 4. The outer side of the round shaft 821 and the inner side of the sleeve 822 are both provided with a number of pointed teeth 823 distributed in a circular array. When the round shaft 821 is inserted into the sleeve 822, the pointed teeth 823 on the round shaft 821 and the sleeve 822 are staggered and engaged, so that the gas expansion shaft 4 drives the clamping shaft 8 to rotate. After the round shaft 821 is inserted into the sleeve 822, the wire coil on the gas expansion shaft 4 must be against the shaft seat 81, so that the hydraulic clamp 83 can clamp one end of the wire coil.

[0026] See also Figure 5 and Figure 6 The hydraulic clamp 83 realizes the clamping action through two symmetrically distributed A chambers 831 opened on the shaft seat 81. A slidable A piston 832 is provided inside the A chamber 831, and a channel 833 for introducing and exporting water in the A chamber 831 is provided inside the shaft seat 81. A transversely distributed B chamber 834 is provided inside the A piston 832, and a slidable B piston 835 is provided inside the B chamber 834. A through hole 8311 for connecting to the front end of the B chamber 834 is provided at the bottom end of the A piston 832, and a slide groove 836 for connecting to the rear half of the B chamber 834 is provided at the top end. A slidable sliding block 837 is provided inside the slide groove 836. The B piston 835 is connected to the bottom of the sliding block 837 through a connecting rod 838. A connecting port 839 located at the top of the A chamber 831 is provided on the shaft seat 81, and a positioning claw 8310 is installed at the top of the sliding block 837. When water is introduced into chamber A 831 through channel 833, as the water pressure increases, piston A 832 is pushed downward, piston B 835 moves inward, causing positioning claw 8310 to extend from shaft seat 81 to press the fiber onto the reel, while the water in chamber A 831 is sucked out. The water pressure in chamber A 831 decreases, piston A 832 and piston B 835 return to their original positions, and positioning claw 8310 retracts into chamber A 831. In actual applications, the water pressure and flow rate can be precisely controlled according to the thickness and material of the fiber to achieve stable clamping of the fiber while avoiding damage to the fiber.

[0027] The hydraulic clamp 83 can use air or liquid as a power source, and mainly drives the movement and reset of the A piston 832 and the B piston 835 through changes in pressure.

[0028] Each time the clamping shaft 8 is docked with the air expansion shaft 4, the position of the hydraulic clamp 83 needs to be adjusted so that the two positioning claws 8310 on the hydraulic clamp 83 are symmetrically distributed up and down. In this way, when the positioning claws 8310 are extended, the fiber is located below the positioning claws 8310. In this way, the hydraulic clamp 83 continues to operate to fix the fiber on the wire roll and rotates with the wire roll. After rotating a certain number of times, in order to prevent the positioning claws 8310 from affecting the fiber winding, the positioning claws 8310 are retracted without affecting the winding and reeling of the wire roll on the air expansion shaft 4.

[0029] See also Figure 7 The unloading shaft 9 is composed of a linear module 91 installed inside the base 2, a movable column 92 installed on the slide and extending to the outside of the base 2, and a shaft body 93 installed at the other end of the movable column 92. A rotatable rectangular column 94 is provided on the shaft body 93, and a torsion spring 95 is installed to reset the rectangular column 94. Under the elastic action of the torsion spring 95, the rectangular column 94 rests on the end of the air expansion shaft 4. When unloading is required, the linear module 91 pushes the movable column 92 out of the base 2, and the rectangular column 94 moves accordingly and pushes the wire coil on the air expansion shaft 4 to unload. By controlling the stroke and speed of the linear module 91, precise control of the wire coil unloading process can be achieved to ensure that the wire coil can be smoothly detached from the air expansion shaft 4 without being damaged.

[0030] During the rotation of the turntable 3, the rectangular column 94 detaches with the movement of the air expansion shaft 4. When the rectangular column 94 detaches from the previous air expansion shaft 4, it will contact the cutting shaft 5, and then detach from the cutting shaft 5 and contact another air expansion shaft 4. In this way, during the rotation of the turntable 3, the rectangular column 94 is always in contact with the air expansion shaft 4, and the rectangular column 94 is in contact with the protrusion 12 on the air expansion shaft 4, and the wire roll is against the protrusion 12. The rectangular column 94 pushes the fiber coil on the wire roll to make the wire roll detach from the air expansion shaft 4.

[0031] A method for using a wool yarn processing fiber pulling and cutting device, 1. Preparation: After the device is started, the turntable 3 starts to rotate under the drive of the motor, and moves the gas expansion shaft 4 to the bottom of the L-shaped support beam 7. At this time, the electric cylinder 11 pushes the fixed seat 10 to move, so that the clamping shaft 8 is docked with the gas expansion shaft 4, and the clamping shaft 8 is in contact with the wire coil placed on the gas expansion shaft 4 in advance.

[0032] 2. Initial winding: Place the fiber on the wire roll near the clamping shaft 8 through the cloth shaft 6, and then use the hydraulic clamp 83 of the clamping shaft 8 to push the fiber against the wire roll. The working principle of the hydraulic clamp 83 is that when water is introduced into the A chamber 831 through the channel 833, the water pressure increases and pushes the A piston 832 downward. The A piston 832 moves inward to drive the B piston 835 and the sliding block 837 connected thereto to move, so that the positioning claw 8310 extends from the shaft seat 81 to clamp the fiber. Then the air expansion shaft 4 rotates, and under its drive, the wire roll begins to rewind the fiber. At the same time, the motor of the cloth shaft 6 drives the reciprocating screw 62 to rotate, so that the reciprocating slider 63 drives the limiting sleeve 64 to reciprocate. After the air expansion shaft 4 rotates a certain number of times, the hydraulic clamp 83 retracts to prevent the fiber from winding on it, and the fixed seat 10 returns to its original position under the drive of the electric cylinder 11, so that the clamping shaft 8 is separated from the air expansion shaft 4, so that the fiber can be evenly wound on the wire roll. In this process, the winding speed can be controlled by adjusting the motor speed of the air expansion shaft 4 according to the specifications and materials of the wire coil and the process requirements of the required wool yarn, and the density and uniformity of the fiber winding can be controlled by adjusting the motor speed of the cloth shaft 6 and the pitch of the reciprocating screw 62.

[0033] 3. Multi-axis switching winding: When the winding of the wire roll on the air expansion shaft 4 is not completed, the turntable 3 rotates again to move the next air expansion shaft 4 to the bottom of the L-shaped support beam 7. At this time, the rotation speed of the previous air expansion shaft 4 remains unchanged, and the fiber continues to reciprocate on the wire roll of the air expansion shaft 4 and is introduced into the wire roll of the previous air expansion shaft 4. The electric cylinder 11 pushes again to make the clamping shaft 8 dock with the new air expansion shaft 4. When the air expansion shaft 4 drives the clamping shaft 8 to adjust the orientation and stops rotating, the two positioning claws 8310 are symmetrically distributed up and down, so that the positioning claws 8310 can capture the fiber on the wire roll when they are extended. When the fiber moves to the wire roll close to the clamping shaft 8 again, the winding operation is completed, and the previous air expansion shaft 4 stops rotating. At this time, the clamping shaft 8 clamps the fiber again and prepares for the cutting operation.

[0034] 4. Fiber cutting stage: After the winding is completed, the cutting shaft 5 starts to work. A guide column 53 is installed inside the hollow shaft column 51 of the cutting shaft 5, and an electric heating knife 55 is installed on the connecting plate 54 on the guide column 53. Under normal circumstances, the electromagnet 57 is energized to adsorb the connecting plate 54 downward, and the electric heating knife 55 retracts from the movable opening 52, and the fiber can move back and forth on the hollow shaft column 51. When it is necessary to cut the fiber, the electromagnet 57 is powered off, the connecting plate 54 is reset under the elastic action of the spring 56, and the electric heating knife 55 extends from the movable opening 52 located at the tangent position of the movable track of the hollow shaft column 51. Since the fiber moves back and forth on the hollow shaft column 51 and passes through the movable opening 52, the electric heating knife 55 can cut it. In actual operation, the heating temperature of the electric heating knife 55 and the elastic coefficient of the spring 56 can be accurately adjusted according to the material and thickness of the fiber to ensure the accuracy and stability of the cutting effect. After cutting the fiber, the new gas expansion shaft 4 starts to rotate and wind, entering the next round of fiber winding work.

[0035] 5. Unloading stage: During the rotation of the turntable 3, when the air expansion shaft 4 resting on the winding wire roll rotates to a specific position, the air expansion shaft 4 releases the clamping of the wire roll. The linear module 91 of the unloading shaft 9 pushes the movable column 92 out of the base 2, and the rectangular column 94 on the shaft 93 at the other end of the movable column 92 moves under the push of the linear module 91. Since the rectangular column 94 originally rests on the end of the air expansion shaft 4 under the elastic action of the torsion spring 95, the rectangular column 94 can push the wire roll on the air expansion shaft 4 to detach. By accurately controlling the stroke and speed of the linear module 91, it is possible to achieve precise control of the wire roll unloading process, ensuring that the wire roll can be smoothly detached from the air expansion shaft 4 without being damaged. After that, the loading operation is carried out, and the new wire coil is introduced into the air expansion shaft 4 again, and this cycle is repeated to realize a series of operations such as pulling and cutting of fibers and winding and unloading of wire coils during wool yarn processing, which effectively improves production efficiency and product quality, and with the precise coordination of various components, it can meet the processing needs of various types of fibers and wire coils.
