Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a traction device for producing composite nylon yarn. Background Technology

[0002] The traction device for composite nylon filament production is a crucial starting device in nylon filament production equipment.

The stable operation of the traction device for composite nylon filament production is the foundation for ensuring the efficient and high-quality operation of the entire nylon filament production process, and directly affects the quality of the final product and production efficiency.

[0003] In the fields of textile printing and dyeing, garment processing, and nonwoven material production, the traction device for composite nylon yarn production is one of the core components affecting production efficiency and finished product quality. Existing technologies generally suffer from the following drawbacks in traditional traction devices: the pressure rollers or guide rods of existing devices are mostly rigid structures, making it difficult to accommodate the transmission requirements of composite nylon yarns with different outer diameters (such as tire cords, conveyor belts, ropes, etc., which need to withstand high-strength tension; and clothing, carpets, fishing nets, etc., which prioritize softness and comfort and may have smaller outer diameters). Frequent manual adjustment of pressure parameters is required (current technologies primarily use spring compression adjustment), increasing downtime and operating costs. Based on this, this utility model designs a traction device for composite nylon yarn production to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a traction device for the production of composite nylon yarn.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A traction device for producing composite nylon yarn includes: a roller, a bracket, and a composite nylon yarn to be tractioned. The composite nylon yarn is located on the outer wall of the roller. Both ends of the roller are rotatably connected to the bracket. An automatically tension-adjustable feeding assembly is installed above the composite nylon yarn. A top plate is installed above the feeding assembly, and a pair of connectors are fixed to the upper surface of the top plate.

[0006] Preferably, the feeding assembly includes: a flexible cylinder, with rings installed at both ends of the inner cavity of the flexible cylinder, a circular block rotatably connected to the inner wall of the rings, a pressure sensor installed at the bottom of the circular block, a filling liquid injected into the interior of the flexible cylinder, the sensing probe of the pressure sensor contacting the filling liquid inside the flexible cylinder, an insertion tube fixedly connected to the top of the inner cavity of the circular block, the insertion tube communicating with the interior of the flexible cylinder, a flexible hose connected to one end of the insertion tube, a hydraulic system connected to the top of the flexible hose, the flexible hose communicating with the medium suction and discharge outlet of the hydraulic system, a first grooved wheel fixedly sleeved on the outer wall of one side of the ring, a second grooved wheel installed above the first grooved wheel, the second grooved wheel being connected to the first grooved wheel via a chain drive, a motor installed on one side of the first grooved wheel, and the output shaft of the motor being fixedly connected to the inner wall of the first grooved wheel.

[0007] Preferably, the flexible tube is connected to the ring via a clamp.

[0008] Preferably, a diagonal rod is fixed between the two rings.

[0009] Preferably, the circular block is connected to the top plate via a connecting assembly, the connecting assembly comprising: a horizontal plate located above the circular block, the horizontal plate being fixedly connected to the frame of the motor, an electric push rod being fixedly attached to the upper surface of the horizontal plate, the housing of the electric push rod being fixedly connected to the top plate, a pair of uprights inserted into the upper surface of the horizontal plate, the uprights penetrating the horizontal plate and being fixedly connected to the circular block, a vertical cylinder being fitted onto the upper part of the outer wall of the uprights, and the top end of the vertical cylinder being fixedly connected to the top plate.

[0010] Preferably, the pair of uprights are arranged symmetrically with respect to the center point of the horizontal plate.

[0011] Preferably, a protective component is installed on the end face of the circular block away from the circular ring. The protective component includes a safety valve, which is installed on the end face of the circular block away from the circular ring.

[0014] Compared with the prior art, the advantages of this utility model are as follows: Through the coordinated operation of various components, the composite nylon yarn to be tractioned is first placed between the idler roller and the flexible drum. Then, the hydraulic system is controlled to inject filling liquid into the flexible drum. As the filling liquid is continuously injected, the pressure intensity of the flexible drum on the composite nylon yarn gradually increases. During this period, the pressure sensor can provide feedback on the pressure intensity applied to the composite nylon yarn, thereby adjusting the tension intensity of the composite nylon yarn. This design can significantly improve the compatibility and automation of composite nylon yarn transmission, effectively solving the problem of incompatibility in transmission of composite nylon yarns with different outer diameters caused by the rigid structure of the pressure roller or guide rod. It eliminates the need for frequent manual adjustment of pressure parameters by spring compression, avoiding operational errors and inconvenience caused by manual adjustment, greatly reducing downtime and lowering operating costs. Through the coordinated operation of various components, when the pressure inside the soft cylinder is too high due to improper system operation and exceeds the predetermined threshold of the safety valve, the safety valve is in the connected state, which can release the filling liquid inside the soft cylinder and discharge it into the box for storage through the vertical pipe, thereby ensuring the safe operation of the device. Through the coordinated operation of various components, the operator can control the electric push rod to raise and lower the horizontal plate, circular block, circular ring and soft cylinder, thereby adjusting the distance between the soft cylinder and the idler roller. In this way, the composite nylon yarn can pass smoothly between the idler roller and the soft cylinder in the early stage of processing, providing certain convenience for the operator.

The feeding assembly includes a flexible cylinder 6, which is made of rubber material, has good flexibility and sealing properties, and can deform under the action of the filling liquid 24, thereby applying appropriate pressure to the composite nylon filament 3. Both ends of the flexible cylinder 6 are equipped with rings 7, which are made of metal and chrome-plated to improve their wear resistance and corrosion resistance, and serve to support and fix the flexible cylinder 6. A circular block 8 is rotatably connected to the inner wall of the circular block 7. The circular block 8 is rotatably connected to the circular block 7 through a sealed bearing. A pressure sensor is installed at the bottom of the circular block 8. Device 9, pressure sensor 9 is a high-precision piezoresistive sensor, characterized by high sensitivity and fast response speed. It can accurately monitor the pressure intensity value of the composite nylon filament 3 in real time and feed this value back to the control system in the form of an electrical signal. The soft cylinder 6 is filled with filling fluid 24, which is a special hydraulic oil with good lubricity, stability and compressibility, ensuring the uniformity of pressure transmission during the deformation of the soft cylinder 6. The sensing probe of pressure sensor 9 is in contact with the filling fluid 24 inside the soft cylinder 6 to accurately sense pressure changes. The inner top of the circular block 8 is fixed with a tube 10, which is made of stainless steel and has good sealing and pressure resistance. The tube 10 is interconnected with the inside of the soft cylinder 6 to ensure... The filling fluid 24 can smoothly enter and exit the flexible cylinder 6 through the insertion tube 10. One end of the insertion tube 10 is connected to a flexible hose 11. The flexible hose 11 is made of high-pressure rubber, which is flexible and bend-resistant, and can adapt to different connection angles. It also has good pressure resistance to ensure stable transmission of the filling fluid 24. The top end of the flexible hose 11 is connected to a hydraulic system 12. The hydraulic system 12 consists of a hydraulic pump, oil tank, control valve, and other components. It can accurately control the injection and discharge of the filling fluid 24 and regulate the internal pressure of the flexible cylinder 6. The medium suction and discharge outlets of the flexible hose 11 and the hydraulic system 12 are interconnected. A first grooved wheel 13 is fixedly sleeved on the outer wall of one side of the ring 7. The first grooved wheel 13 is made of high-strength engineering plastic, which is lightweight and wear-resistant.A second grooved wheel 14 is installed above the first grooved wheel 13.

The flexible cylinder 6 is connected to the ring 7 via a clamp 25. The clamp 25 is made of stainless steel, which has good fastening and corrosion resistance, and can ensure a firm connection between the flexible cylinder 6 and the ring 7, preventing leakage of the filling liquid 24. A diagonal rod 26 is fixed between the two rings 7. The diagonal rod 26 plays a role in strengthening the structural stability and improving the strength of the entire feeding assembly.

[0020] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the traction device for producing composite nylon yarn according to this utility model, the circular block 8 is connected to the top plate 4 via a connecting assembly. The connecting assembly includes a horizontal plate 17, which is located above the circular block 8. The horizontal plate 17 is made of high-strength aluminum alloy, featuring light weight and high strength. The horizontal plate 17 is fixedly connected to the frame of the motor 16 to ensure the stability of the horizontal plate 17. An electric push rod 18 is fixedly attached to the upper surface of the horizontal plate 17. The electric push rod 18 is a linear electric push rod, featuring large thrust and precise stroke, and can achieve extension and retraction according to the operator's control. In motion, the housing of the electric push rod 18 is fixedly connected to the top plate 4. A pair of upright rods 19 are inserted into the upper surface of the horizontal plate 17 and are fixedly connected to the horizontal plate 17. The upright rods 19 pass through the horizontal plate 17 and are fixedly connected to the circular block 8. A vertical cylinder 20 is fitted on the upper part of the outer wall of the upright rod 19. The vertical cylinder 20 plays a guiding and limiting role to ensure that the upright rod 19 remains stable during the up and down movement. The top of the vertical cylinder 20 is fixedly connected to the top plate 4. The pair of upright rods 19 are symmetrically arranged with respect to the center point of the horizontal plate 17. This symmetrical design can ensure that the soft cylinder 6 is subjected to uniform force during the lifting and lowering process and improve the accuracy of adjustment.

[0021] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown in the preferred embodiment of the traction device for producing composite nylon yarn according to this utility model, a protective component is installed on the end face of the circular block 8 away from the circular ring 7. The protective component includes a safety valve 21, which is installed on the end face of the circular block 8 away from the circular ring 7. The safety valve 21 is a spring-loaded safety valve, which has the characteristics of high sensitivity and good reliability. When the internal pressure of the flexible cylinder 6 exceeds the set value, it can automatically open to release pressure. The inlet of the safety valve 21 is in contact with the filling liquid 24, and the outlet of the safety valve 21 is connected to a vertical pipe 22. The vertical pipe 22 is made of stainless steel and has good pressure resistance and corrosion resistance. The bottom end of the support 2 is fixedly connected to a box 23, which is used to store the filling liquid 24 that leaks from the soft cylinder 6. The box 23 adopts a sealed design to prevent the filling liquid 24 from leaking. The box 23 is fixedly connected to the support 2 to ensure the stability of the position of the box 23. A U-shaped rod 27 is fixedly connected to the front surface of the support 2. Multiple limiting wheels 28 are equidistantly rotatably connected to the outer wall of the U-shaped rod 27. The limiting wheels 28 are rotatably connected to the U-shaped rod 27 through ball bearings. The limiting wheels 28 are in contact with the composite nylon filament 3. The limiting wheels 28 can limit the composite nylon filament 3 and prevent the multiple composite nylon filaments 3 from getting tangled together when being pulled.

[0022] Working principle: Composite nylon filament placement and pressure adjustment section: First, the composite nylon yarn 3 to be tractioned is placed smoothly between the idler roller 1 and the soft cylinder 6, thus laying the foundation for subsequent pressure application and composite nylon yarn transmission. Then, the hydraulic system 12 is controlled to inject filling liquid 24 into the soft cylinder 6. As the filling liquid 24 is continuously injected, the flexible cylinder 6 deforms, thereby gradually increasing the pressure applied to the composite nylon filament 3. During this process, the pressure sensor 9 monitors the pressure intensity value of the composite nylon filament 3 in real time and feeds this value back to the control system. The operator can accurately control the injection volume of the filling liquid 24 of the hydraulic system 12 according to the characteristics of composite nylon filaments with different outer diameters and transmission requirements, and with reference to the value fed back by the pressure sensor, so as to flexibly adjust the tension intensity of the composite nylon filament. This design has significant advantages over the traditional method of frequently adjusting the pressure parameters by spring compression. It avoids the operation errors and inconveniences that may be caused by manual adjustment, greatly improves the compatibility and automation of composite nylon filament transmission, effectively reduces downtime, and lowers operating costs. When the pressure intensity applied by the flexible cylinder 6 to the composite nylon filament 3 reaches a suitable value, the injection of filling liquid 24 into the flexible cylinder 6 is stopped to ensure that the composite nylon filament 3 can maintain stable tension during subsequent transmission.

[0023] Composite nylon filament transmission drive section: After the pressure applied by the flexible cylinder 6 to the composite nylon filament 3 stabilizes, the drive motor 16 starts running, driving the second grooved wheel 14 to rotate. The second grooved wheel 14 transmits power to the first grooved wheel 13 through the chain belt 15. The first grooved wheel 13 then drives the ring 7 and the flexible cylinder 6 to rotate at a constant speed. Since the flexible cylinder 6 and the composite nylon filament 3 are in a tight contact state, the rotation of the flexible cylinder 6 will drive the composite nylon filament 3 to move forward, thereby completing the traction operation of the composite nylon filament 3.

[0024] Safety protection components: During device operation, all components work together to ensure safety. When the pressure inside the soft cylinder 6 continues to increase due to improper system operation and exceeds the threshold preset by the safety valve 21, the safety valve 21 automatically switches to the connected state. At this time, the filling liquid 24 inside the soft cylinder 6 will be discharged through the safety valve 21 and discharged into the box 23 for storage through the vertical pipe 22. This process can reduce the pressure inside the soft cylinder 6 in time, prevent damage to the device due to excessive pressure, and ensure the safe and stable operation of the device.

[0025] Distance adjustment section: To ensure that the composite nylon yarn 3 can smoothly pass through the gap between the idler roller 1 and the soft cylinder 6 in the early stage of processing, the operator can operate the electric push rod 18. The electric push rod 18 moves in a telescopic motion, driving the horizontal plate 17 to rise and fall. The horizontal plate 17 then drives the circular block 8, the circular ring 7 and the soft cylinder 6 to rise and fall synchronously, thereby realizing the adjustment of the distance between the soft cylinder 6 and the idler roller 1. This design provides great convenience to the operator, who can flexibly adjust the spacing according to the composite nylon yarn of different thicknesses and materials, ensuring the smooth progress of the traction operation.
