Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a traction suction tube for cutting ends of textile yarn. Background Technology

[0002] After the yarn is prepared, it needs to be wound onto a spindle. Since the yarn is very long, it can be continuously fed. When the required weight of yarn is wound onto the spindle, it is necessary to change the spindle and rewind. At this time, the yarn needs to be cut and the cut end is wound onto a new spindle. During this process, the cut yarn end needs to be pulled.

[0003] The yarn end traction suction nozzle is a key component in textile machinery (such as automatic winding machines and doubling machines) used to capture and guide yarn ends. Its function is to use negative pressure airflow to adsorb broken or loose yarn ends, thereby achieving automatic yarn feeding, splicing, or cleaning. However, the existing traction suction tube has a low gas flow rate and weak adsorption force, which cannot effectively adsorb yarn ends. In addition, its structure is complex, inconvenient to process and manufacture, and costly. Utility Model Content

[0004] The purpose of this invention is to provide a traction suction tube for cutting the ends of textile yarns, which solves the problems of weak suction force, inability to effectively suction the ends of yarns, complex structure, inconvenient processing and manufacturing, and high cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-speed suction nozzle, wherein a cable inlet channel is provided inside the high-speed suction nozzle, and the diameter of the cable inlet of the cable inlet channel is larger than the diameter of the cable outlet of the cable inlet channel;

[0008] The tube body has one end connected to the negative pressure port of the negative pressure exhaust device, and the inner diameter of the tube body is larger than the outlet diameter of the high-speed suction nozzle.

[0009] The connecting part is used to connect the high-speed suction nozzle to one end of the tube body. The connecting part is bent and configured with the high-speed suction nozzle. The connecting part is provided with a wire channel communicating with the inlet channel. The inlet of the wire channel and the outlet of the high-speed suction nozzle have the same shape and size. The outlet of the wire channel and the inner hole of one end of the tube body have the same shape and size.

[0010] Furthermore, the connecting part is inclined to the left along the axial direction of the tube body, and the inlet channel in the high-speed suction nozzle and the wire channel in the connecting part cooperate to form a bent channel.

[0011] Furthermore, the side of the high-speed suction nozzle away from the connecting part is inclined, and the inlet of the cable inlet channel is located on the inclined surface.

[0012] Furthermore, both the high-speed suction nozzle and the connecting part are inclined to the left along the axial direction of the tube body. The leftward inclination angle of the high-speed suction nozzle is greater than the leftward inclination angle of the connecting part. The inlet channel in the high-speed suction nozzle and the wire channel in the connecting part also form a bent channel.

[0013] Furthermore, the inlet of the high-speed suction nozzle is located on the side of the high-speed suction nozzle away from the connecting part, and notches are provided on both sides of the inlet in the width direction.

[0014] Furthermore, the outlet of the incoming line channel is provided in the shape of an oblong hole, or the inlet of the conductor channel is provided in the shape of an oblong hole.

[0018] This utility model provides a traction suction tube for cutting the end of textile yarn, comprising a high-speed suction nozzle, a tube body, and a connecting part. The connecting part is bent and configured with the high-speed suction nozzle. The high-speed suction nozzle has an inlet channel, the diameter of which is larger than ... In this traction suction tube, by setting the inlet channel from wide to narrow along the direction of yarn entry, the airflow velocity at the inlet of the traction suction tube can be increased, and the pressure is low at the narrow part of the inlet channel, which facilitates yarn entry. Furthermore, the guide channel is set from narrow to wide along the direction of yarn entry, and the cooperation between the guide channel and the inlet channel can generate a large suction force. Under this large suction force, the yarn end is more firmly pulled and less likely to detach from the traction suction tube. In addition, it also has an energy-saving effect.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Example 1

[0033] refer to Figure 1 and Figure 2 This example provides a traction suction tube for cutting the ends of textile yarns. It is used in ring spinning and spring-loaded shaped tube compact spinning. Specifically, this traction suction tube is used in conjunction with a negative pressure exhaust collection device. The outlet of the traction suction tube is connected to the air inlet of the negative pressure exhaust collection device. When the negative pressure exhaust device is working, the yarn end is attracted by the traction suction tube, and the yarn end is pulled and drawn under the action of the suction force.

[0034] refer to Figure 1 and Figure 2 The traction suction tube includes a high-speed suction nozzle 1, a tube body 2, and a connecting part 3. The connecting part 3 is used to connect the high-speed suction nozzle 1 to the tube body 2. The high-speed suction nozzle 1, the tube body 2, and the connecting part 3 are integrally molded, resulting in a better sealing effect for the entire structure.

[0035] refer to Figure 1 and Figure 2During operation, the traction suction tube is set vertically, the inlet 11 of the high-speed suction nozzle 1 faces the yarn 6, and the connecting part 3 is set to the left along the axial direction of the tube body 1. At this time, the connecting part of the high-speed suction nozzle is bent. The bending setting allows the inlet 11 of the high-speed suction nozzle 1 to face the yarn 6 better, which facilitates the adsorption of the cut yarn 6 ends.

[0036] refer to Figures 1-5 The high-speed suction nozzle 1 is provided with an inlet channel 4, the diameter of the inlet of the inlet channel 4 is larger than the diameter of the outlet of the inlet channel 4; the diameter of the inner hole at one end of the tube body 2 is larger than the diameter of the outlet of the high-speed suction nozzle 1; the connecting part 3 is provided with a wire channel 5, and the inlet channel 4 and the wire channel 5 cooperate to form a bent channel; the diameter of the inlet of the wire channel 5 is the same as the shape and size of the outlet of the high-speed suction nozzle 1, and the shape and size of the outlet of the wire channel 5 is the same as the inner hole at one end of the tube body 2. By setting the inlet channel 4 from wide to narrow along its axial direction from top to bottom, the airflow speed at the cotton inlet of the traction suction tube can be increased. The airflow is large and the pressure is low at the narrow part, which facilitates cotton entry. The guide channel 5 is set from narrow to wide along its axial direction from top to bottom. The cooperation between the guide channel 5 and the inlet channel 4 can generate a large suction force. After the yarn enters this traction suction tube, it bends along the inlet direction. At this time, the yarn end is more firmly pulled under the action of large suction force and bending, and it is not easy to fall out of this traction suction tube.

[0037] refer to Figures 1-5 The end face of the inlet 11 of the high-speed suction nozzle 1 is inclined, which facilitates the entry of the yarn end. The outlet of the high-speed suction nozzle 1 is waist-shaped or the inlet of the connecting part 3 is waist-shaped. The waist-shaped hole shape can limit the yarn in the short axis direction while ensuring that the yarn end can enter, thus preventing the yarn from moving too much in the short axis direction.

[0038] refer to Figures 1-5 The connection points between the inlet channel 4 and the conductor channel 5, as well as the connection point between the conductor channel 5 and the inner hole of the tube 2, are all rounded. The inlet channel 4, the connection point of the conductor channel 5, and the inner wall of the inner hole of the tube 2 are all smooth surfaces. This structural design ensures smooth yarn entry into the traction suction tube, minimizing the likelihood of yarn snagging.

[0039] In summary, by setting the inlet channel 4 from wide to narrow along the direction of yarn entry in this traction suction tube, the airflow velocity at the inlet of the traction suction tube can be increased, the pressure is reduced, and the yarn entry is facilitated. Furthermore, the guide channel 5 is set from narrow to wide along the direction of yarn entry. The cooperation between the guide channel 5 and the inlet channel 4 can generate a large suction force. Under the action of the large suction force, the yarn end is more firmly pulled and is not easy to detach from this traction suction tube. In addition, it can also play an energy-saving role.

[0040] Example 2

[0041] The content of this embodiment is basically the same as that of Embodiment 1, except that:

[0042] refer to Figure 6 and Figure 7 Both the high-speed suction nozzle 1 and the connecting part 3 are inclined to the left along the axial direction of the tube body 1. The leftward inclination angle of the high-speed suction nozzle 1 is greater than that of the connecting part 3. The inlet channel 4 inside the high-speed suction nozzle 1 and the wire channel 5 inside the connecting part 3 also form a bent channel. The inlet 11 of the high-speed suction nozzle 1 is located on the side of the high-speed suction nozzle 1 away from the connecting part 3. Notches 8 are provided on both sides of the inlet 11 in the width direction. This structure of the traction suction tube is used in mesh loop compact spinning. By inclination of both the high-speed suction nozzle 1 and the connecting part 2 to the left along the axial direction of the tube body 1, the position of the high-speed suction nozzle 1 can be more closely aligned with the triangular area of ​​the yarn 6 and the mesh loop 7, achieving better end-feeding performance. During the movement of the yarn 6 around the mesh loop 7, the cotton fibers on the yarn 6 are easily stuck to the mesh loop 7. At this time, the traction suction tube of this structure can also adsorb the cotton fibers stuck to the mesh loop 7, ensuring the cleanliness of the surface of the mesh loop 7 and preventing cotton fibers from floating in the working environment.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
