Technical Field

[0001] This utility model relates to the field of yarn splicing machine technology, and in particular to a dual-speed yarn splicing machine. Background Technology

[0002] A yarn blending machine is a key piece of equipment in the textile industry used to combine multiple yarns into a single composite yarn. In denim production, yarn blending machines can combine yarns with different properties, giving the final product a unique texture and performance. Traditional yarn blending machines are typically designed to process a single type of yarn, ensuring uniform tension throughout the processing, which is crucial for maintaining fabric quality and appearance. However, with the growing market demand for multi-functional fabrics, yarn blending machines capable of handling multiple yarns with different properties and tension requirements simultaneously are becoming increasingly important.

[0003] Existing yarn blending technologies often struggle to effectively address the issue of combining yarns with different tensions. When attempting to combine two yarns with significantly different tensions, traditional yarn blending machines may cause one yarn to be too tight or too loose, affecting the overall quality of the finished fabric.

[0004] The purpose of this invention is to solve the problem that traditional yarn splicing machines cannot effectively handle the merging of yarns with different tensions. Utility Model Content

[0005] The purpose of this invention is to solve the problems of the traditional yarn blending machine's sharpening device being difficult to clean after jamming, and the traditional yarn blending machine being unable to effectively handle the merging of yarns with different tensions. This invention adopts the following technical solution:

The first yarn feeding path and the second yarn feeding path are respectively used to feed yarns with different tensions, wherein at least one yarn has a first tension and at least one yarn has a second tension. The first yarn feeding path includes a speed regulating mechanism for adjusting the yarn feeding speed of the first yarn feeding path.

A first motor is installed on one side of the L-shaped support, and the rotor of the first motor is drivenly connected to the pressure roller or the pressure roller.

[0008] In the dual-speed yarn splicing machine described above, the surface of the pressure roller and / or pressure roller is fitted with an elastomer.

[0009] In the dual-speed yarn splicing machine described above, the elastomer is made of one of the following materials: rubber, polyurethane, or ethylene-vinyl acetate copolymer.

[0010] As described above, in a dual-speed yarn splicing machine, a yarn winding roller is installed on one side of the frame, and yarn winding roller supports are installed at both ends of the yarn winding roller. A second motor for driving the yarn winding roller to rotate is installed inside the yarn winding roller supports.

[0011] As described above, in a dual-speed yarn splicing machine, a control box is provided on one side of the frame. The control box is used to control the rotation speed of the rotor of the first motor and the rotor of the second motor.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4As shown, this utility model proposes a dual-speed yarn feeding machine, including a frame 1. The frame 1 has at least one first yarn feeding path 2 and at least one second yarn feeding path 3. The first yarn feeding path 2 and the second yarn feeding path 3 are used to feed yarns with different tensions, wherein at least one yarn has a first tension and at least one yarn has a second tension. The first yarn feeding path 2 includes a speed regulating mechanism 21 for adjusting the yarn feeding speed. Yarns with different tensions are fed through the first yarn feeding path 2 and the second yarn feeding path 3 within the frame 1, wherein at least one yarn has a first tension and at least one yarn has a second tension. Preferably, the higher tension yarn is fed through the first yarn feeding path 2, and the lower tension yarn is fed through the second yarn feeding path 3. The yarn feeding speed of the second yarn feeding path 3 is controlled by a subsequent yarn winding mechanism. The first yarn feeding path 2 is equipped with a speed regulating mechanism 21, which can precisely adjust the yarn feeding speed of this path to ensure that the two yarns maintain their respective required tension levels during the merging process, thus preventing one yarn from being too tight or too loose. By finely adjusting the speed of the higher tension yarn path through the speed regulating mechanism 21, combined with the speed control of the lower tension yarn path through the yarn winding mechanism, a perfect combination of two yarns with different tensions is achieved. Both yarns maintain their proper tension, preventing quality problems caused by tension differences.

[0027] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the speed regulating mechanism 21 includes a pressure roller 212, with L-shaped supports 215 mounted at both ends of the pressure roller 212. The L-shaped supports 215 are fixedly connected to the frame 1. A pressure roller 211 is disposed above the pressure roller 212. Lifting arms 216 are mounted at both ends of the pressure roller 211. One end of the lifting arm 216 is hinged to the L-shaped support 215, and the other end of the lifting arm 216 is hinged to a lifting part 217. One end of the lifting part 217 is hinged to the L-shaped support 215. A first motor 214 is mounted on one side of the L-shaped support 215. The rotor of the first motor 214 is drively connected to the pressure roller 212 or the pressure roller 211. The first motor 214 drives the pressure roller 212 or the pressure roller 211 to rotate. By adjusting the speed of the first motor 214, the travel speed of the yarn is controlled, thereby precisely adjusting the yarn tension. The articulated design of the lifting arm 216 and the lifting part 217 allows the pressure roller 211 to move up and down as needed, ensuring that the pressure roller 211 can apply appropriate pressure to yarns of different thicknesses and types, maintain stable contact and maintain constant tension, thereby precisely adjusting the yarn feeding speed.

[0028] Optionally, in some embodiments, the lifting part 217 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0029] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, an elastomer 213 is mounted on the surface of the pressure roller 212 and / or the pressure roller 211. The elastomer 213 is made of one of the following materials: rubber, polyurethane, or ethylene-vinyl acetate copolymer. Due to the presence of the elastomer 213, when the pressure roller 212 contacts the pressure roller 211, the elastomer 213 deforms under pressure, absorbing impact force and providing a cushioning effect, avoiding direct collision between hard materials, reducing mechanical wear, and extending the service life of the equipment. The softness of the elastomer 213 increases the contact area with the yarn, providing better friction, ensuring greater stability of the yarn during transmission, preventing slippage, and helping to maintain a constant tension level. The gentle contact of the elastomer 213 reduces damage to the yarn surface.

[0030] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a yarn winding roller 4 is mounted on one side of the frame 1, and yarn winding roller supports 5 are mounted at both ends of the yarn winding roller 4. A second motor for driving the rotation of the yarn winding roller 4 is installed inside the yarn winding roller supports 5. The yarn winding roller 4 is responsible for receiving the yarn after it has been combined from the first yarn supply path 2 and the second yarn supply path 3. The yarn winding roller supports 5 provide a stable support structure for the yarn winding roller 4, ensuring that the yarn winding roller 4 rotates smoothly during operation. The second motor 6 is used to drive the rotation of the yarn winding roller 4. By precisely controlling the speed of the second motor 6, the winding speed of the yarn winding roller 4 can be adjusted to match the speed of the first yarn supply path 2 and the second yarn supply path 3.

[0031] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a control box 6 is provided on one side of the frame 1. The control box 6 is used to control the rotational speed of the rotors of the first motor 214 and the second motor. It integrates a control system and necessary electrical components for precisely controlling the rotational speeds of the first motor 214 and the second motor. The control box 6 can adjust the motor speeds through preset programs or real-time monitoring to ensure tension consistency and speed coordination during the yarn feeding path and yarn winding process.

[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the first yarn supply path 2 includes at least one first tension roller 22, which is used to adjust and stabilize the tension of the yarn in the first yarn supply path 2. The second yarn supply path 3 includes at least one second tension roller 31, which is used to adjust and stabilize the tension of the yarn in the second yarn supply path 3. By setting the first tension roller 22 and the second tension roller 31, precise tension control can be performed on two yarns with different tensions, ensuring that they maintain their respective required tension levels during the merging process.

[0033] Example 1:

[0034] This utility model proposes a dual-speed yarn feeding machine, including a frame 1. At least one first yarn feeding path 2 and at least one second yarn feeding path 3 are provided within the frame 1. The first and second yarn feeding paths 2 and 3 are respectively used to feed yarns with different tensions, wherein at least one yarn has a first tension and at least one yarn has a second tension. The first yarn feeding path 2 includes a speed regulating mechanism 21 for adjusting the yarn feeding speed. Yarns with different tensions are fed through the first and second yarn feeding paths 2 and 3 within the frame 1, wherein at least one yarn has a higher tension and at least one yarn has a lower tension. Preferably, the higher tension yarn is fed through the first yarn feeding path 2, and the lower tension yarn is fed through the second yarn feeding path 3. The yarn feeding speed of the second yarn feeding path 3 is controlled by a subsequent yarn winding mechanism. The first yarn feeding path 2 is equipped with a speed regulating mechanism 21, which can precisely adjust the yarn feeding speed of this path to ensure that the two yarns maintain their respective required tension levels during the merging process, thus preventing one yarn from being too tight or too loose. By finely adjusting the speed of the higher tension yarn path through the speed regulating mechanism 21, combined with the speed control of the lower tension yarn path through the yarn winding mechanism, a perfect combination of two yarns with different tensions is achieved. Both yarns maintain their proper tension, preventing quality problems caused by tension differences.

[0035] The speed regulating mechanism 21 includes a pressure roller 212, with L-shaped supports 215 mounted at both ends of the pressure roller 212. The L-shaped supports 215 are fixedly connected to the frame 1. A pressure roller 211 is positioned above the pressure roller 212, and lifting arms 216 are mounted at both ends of the pressure roller 211. One end of the lifting arm 216 is hinged to the L-shaped support 215, and the other end of the lifting arm 216 is hinged to a lifting part 217, which is a hydraulic cylinder. One end of the lifting part 217 is hinged to the L-shaped support 215. A first motor 214 is mounted on one side of the L-shaped support 215, and the rotor of the first motor 214 is connected to the pressure roller 212 or the pressure roller 211 for transmission. The first motor 214 drives the pressure roller 212 or the pressure roller 211 to rotate. By adjusting the speed of the first motor 214, the travel speed of the yarn is controlled, thereby precisely adjusting the yarn tension. The articulated design of the lifting arm 216 and the lifting part 217 allows the pressure roller 211 to move up and down as needed, ensuring that the pressure roller 211 can apply appropriate pressure to yarns of different thicknesses and types, maintain stable contact and maintain constant tension, thereby precisely adjusting the yarn feeding speed.

[0036] The first yarn supply path 2 includes at least one first tension roller 22, which is used to adjust and stabilize the tension of the yarn in the first yarn supply path 2. The second yarn supply path 3 includes at least one second tension roller 31, which is used to adjust and stabilize the tension of the yarn in the second yarn supply path 3. By setting the first tension roller 22 and the second tension roller 31, precise tension control can be performed on two yarns with different tensions, ensuring that they maintain their respective required tension levels during the merging process.

[0037] An elastomer 213 is mounted on the surface of the pressure roller 212 and / or the pressure roller 211. The elastomer 213 is made of rubber. Due to the presence of the elastomer 213, when the pressure roller 212 contacts the pressure roller 211, the elastomer 213 deforms under pressure, absorbing impact force and providing a cushioning effect. This avoids direct collision between hard materials, reduces mechanical wear, and extends the service life of the equipment. The softness of the elastomer 213 increases the contact area with the yarn, providing better friction and ensuring greater stability of the yarn during transmission, preventing slippage and helping to maintain a constant tension level. The gentle contact of the elastomer 213 reduces damage to the yarn surface.

[0038] A yarn winding roller 4 is mounted on one side of the frame 1. Yarn winding roller supports 5 are mounted at both ends of the yarn winding roller 4. A second motor for driving the rotation of the yarn winding roller 4 is installed inside the yarn winding roller supports 5. The yarn winding roller 4 is responsible for receiving the yarn after it has been combined from the first yarn supply path 2 and the second yarn supply path 3. The yarn winding roller supports 5 provide a stable support structure for the yarn winding roller 4, ensuring smooth rotation during operation. The second motor 6 drives the rotation of the yarn winding roller 4. By precisely controlling the speed of the second motor 6, the winding speed of the yarn winding roller 4 can be adjusted to match the speed of the first yarn supply path 2 and the second yarn supply path 3.

[0039] A control box 6 is installed on one side of the frame 1. The control box 6 is used to control the rotational speed of the rotors of the first motor 214 and the second motor. It integrates a control system and necessary electrical components for precise control of the speeds of the first motor 214 and the second motor. The control box 6 can adjust the motor speed through preset programs or real-time monitoring to ensure tension consistency and speed coordination during the yarn feeding path and yarn winding process.

[0040] Specifically, the working principle of this invention is as follows:

[0041] By independently controlling the speeds of at least two yarn supply paths, it is ensured that at least two yarns with different tensions maintain their respective required tension levels during the merging process. Specifically, the first yarn supply path 2 is equipped with a speed regulating mechanism 21, which includes a pressure roller 212, a pressure roller 211, a lifting arm 216, a lifting section 217 (such as a hydraulic cylinder), and a first motor 214. The first motor 214 drives the pressure roller 212 or the pressure roller 211 to rotate, and by adjusting its rotation speed, the travel speed of the higher tension yarn is precisely controlled, thereby achieving fine adjustment of the yarn tension. At the same time, the lifting arm 216 and the lifting section 217 allow the pressure roller 211 to move up and down to accommodate yarns of different thicknesses and types, maintain stable contact, and maintain constant tension.

[0042] The yarn feeding speed of the second yarn feeding path 3 is controlled by the yarn winding roller 4. The second motor drives the yarn winding roller 4 to rotate, adjusting the winding speed of the lower tension yarn to ensure it matches the speed of the first yarn feeding path 2. Furthermore, the first yarn feeding path 2 and the second yarn feeding path 3 are respectively equipped with a first tension roller 22 and a second tension roller 31 to further adjust and stabilize the yarn tension in their respective paths. The elastomer 213 (such as rubber) mounted on the surface of the pressure roller 212 and / or pressure roller 211 deforms under pressure, providing a cushioning effect and better friction, ensuring stability and tension consistency during yarn transmission, and reducing mechanical wear and yarn damage.

[0043] The entire system is intelligently controlled by a control box 6 installed on one side of the frame 1. The control box 6 integrates the control system and necessary electrical components, and can adjust the speed of the first motor 214 and the second motor according to preset programs or real-time monitoring data to ensure the consistency of tension and speed coordination during the yarn feeding path and yarn winding process.

[0044] In summary, this invention solves the problem that traditional yarn splicing machines cannot effectively handle the merging of yarns with different tensions.
