Description

Technical Field

[0001] The utility model relates to the technical field of open-end spinning, in particular to a spinning cup for open-end spinning. Background Technique

[0002] Open-end spinning refers to open-end spinning, which is a new spinning technology that uses air flow to condense and twist fibers in a spinning cup rotating at high speed and output yarn. It does not use spindles and mainly relies on multiple components such as a carding roller, a spinning cup, and a false-twist device. The carding roller is used to grab and card the cotton strip fibers fed in. The centrifugal force generated by its high-speed rotation can throw out the grabbed fibers. The spinning cup is a small metal cup, and its rotation speed is more than 10 times higher than that of the carding roller. The centrifugal action generated thereby discharges the air in the cup to the outside; according to the principle of fluid pressure, cotton fibers enter the air flow cup and form a fiber flow, which continuously moves along the inner wall of the cup.

[0003] Conventional spinning cups are limited by the simplicity of their structure and the installation structure, resulting in relatively limited overall rotational balance. In the case of long-term high-speed rotation, the rotation axis will shift, which not only affects its service life but also affects the spinning effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a spinning cup for open-end spinning is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spinning cup for open-end spinning to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A spinning cup for open-end spinning includes a spinning cup assembly and a counterweight structure. The middle section of the bottom of the spinning cup assembly is connected with a counterweight structure, and the lower end of the counterweight structure is connected with a stabilizing sleeve. Moreover, a core shaft tube is inserted into the top of the stabilizing sleeve. The counterweight structure includes a fixing ring, an assembly hole, and a counterweight block. The surface of the fixing ring is provided with an assembly hole, and the counterweight block vertically penetrates through the inside of the assembly hole.

[0007] Further, the spinning cup assembly includes a cup body, a condensation groove, and a chip discharge hole. The lower end of the inner wall of the cup body is provided with a condensation groove, and a chip discharge hole is opened below the condensation groove.

[0008] Further, the chip discharge hole is horizontally opened in the conical structure at the lower end of the spinning cup assembly, and six groups of chip discharge holes are arranged in a circular array with the spinning cup assembly as the center.

[0009] Further, the spinning cup assembly further includes a stabilizing shaft, a limiting groove, and a core shaft hole. The bottom of the cup body is vertically connected with a stabilizing shaft, a limiting groove is opened on the surface of the stabilizing shaft, and a core shaft hole is vertically opened in the center of the inside of the stabilizing shaft.

[0010] Furthermore, the fixing ring is fixedly connected to the cup body, and the stabilizing shaft is integrally structured with the cup body.

[0011] Furthermore, the assembly holes are arranged in a circular array centered on the fixing ring, and the counterweight blocks are threadedly connected to the assembly holes.

[0012] Furthermore, the stabilizing sleeve includes a fixing tube, balls and exhaust holes. Balls are movably embedded on the inner wall surface of the fixing tube, and exhaust holes are formed at the bottom of the fixing tube.

[0013] Furthermore, the balls are distributed in a circular array centered on the fixing tube, and the surface diameter of the balls matches the inner diameter of the limiting grooves.

[0014] The utility model provides a spinning cup for air-jet spinning, which has the following beneficial effects:

[0015] 1. In the utility model, a counterweight structure is arranged in the middle section of the spinning cup assembly. Since a number of assembly holes are arranged in a circular array on the surface of the fixing ring, and by using the threaded connection structure between the counterweight blocks and the assembly holes, an appropriate number of counterweight blocks can be penetrated into the interior of the assembly holes and fixed as required. By using the above structure, the combined use of the fixing ring and the counterweight blocks can ensure the dynamic balance of the entire device structure during rotation as much as possible, which can not only guarantee the quality of spinning, but also ensure the service life of the device structure itself. In addition, through the chip removal holes formed on the conical surface of the cup body, the granular impurities adhered to the fibers are directly discharged from the interior of the chip removal holes, so as to reduce the accumulation of impurities inside the cup body as much as possible. The structure of the chip removal holes is simple, which can effectively reduce the cleaning steps and improve the production efficiency, making the use of the overall structure of the device convenient.

[0016] 2. In the utility model, a stabilizing sleeve is connected to the lower end of the spinning cup assembly. Among them, three groups of limiting grooves are equidistantly arranged on the surface of the stabilizing shaft, and three groups of balls are arranged in a circular array from top to bottom on the inner wall surface of the fixing tube. Since a part of the balls are embedded in the limiting grooves, when the entire spinning cup assembly rotates at a high speed, it will rotate inside the fixing tube by using the contact structure of the limiting grooves and the balls. By using the above structure, while minimizing the contact surface of the structure, it can also ensure the axial stability of the rotation of the entire spinning cup assembly during high-speed rotation, which not only guarantees the service life of the structure, but also guarantees the operating stability of the structure to ensure the quality during spinning processing. In addition, the exhaust holes cooperate with the hollow core shaft tube and the core shaft hole, which can provide a certain degree of ventilation and heat dissipation under the high-speed rotation of the spinning cup assembly, thereby reducing the heat generated by the friction between the structures and playing a role in self-maintenance of the structure.

[0022] The following further describes in detail the implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figures 1 to 4 shown, a spinning cup for rotor spinning includes a spinning cup assembly 1 and a weight structure 2. The middle section of the bottom of the spinning cup assembly 1 is connected to the weight structure 2, and the lower end of the weight structure 2 is connected to a stabilizing sleeve 3. Moreover, a core shaft tube 4 is inserted into the top of the stabilizing sleeve 3. The weight structure 2 includes a fixed ring 201, an assembly hole 202, and a weight block 203. An assembly hole 202 is provided on the surface of the fixed ring 201, and a weight block 203 vertically penetrates through the inside of the assembly hole 202. The fixed ring 201 is fixedly connected to the cup body 101, and the stabilizing shaft 104 is integrally formed with the cup body 101. The assembly holes 202 are arranged in a circular array with the fixed ring 201 as the center, and the weight block 203 is threadedly connected to the assembly hole 202. By providing a weight structure 2 in the middle section of the spinning cup assembly 1, since a plurality of assembly holes 202 are arranged in a circular array on the surface of the fixed ring 201, using the threaded connection structure between the weight block 203 and the assembly hole 202, an appropriate number of weight blocks 203 can be penetrated through the inside of the assembly hole 202 and fixed as needed.

[0024] As Figures 1 to 4As shown in the figure, the spinning cup assembly 1 includes a cup body 101, a condensing groove 102 and a chip discharging hole 103. The lower end of the inner wall of the cup body 101 is provided with a condensing groove 102, and a chip discharging hole 103 is opened below the condensing groove 102. The chip discharging hole 103 is horizontally opened in the conical structure at the lower end of the spinning cup assembly 1, and six groups of chip discharging holes 103 are arranged in a circular array with the spinning cup assembly 1 as the center. The spinning cup assembly 1 further includes a stabilizing shaft 104, a limiting groove 105 and a core shaft hole 106. The bottom of the cup body 101 is vertically connected with a stabilizing shaft 104, and a limiting groove 105 is opened on the surface of the stabilizing shaft 104. Moreover, a core shaft hole 106 is vertically opened in the center of the stabilizing shaft 104. The stabilizing sleeve 3 includes a fixed tube 301, a ball 302 and an exhaust hole 303. The inner wall surface of the fixed tube 301 is movably inlaid with a ball 302, and an exhaust hole 303 is opened at the bottom of the fixed tube 301. The balls 302 are distributed in a circular array with the fixed tube 301 as the center, and the surface diameter of the balls 302 matches the inner diameter of the limiting groove 105. By equidistantly opening three groups of limiting grooves 105 on the surface of the stabilizing shaft 104 and arranging three groups of balls 302 in a circular array from top to bottom on the inner wall surface of the fixed tube 301, since a part of the balls 302 is embedded in the limiting groove 105, when the whole spinning cup assembly 1 rotates at a high speed, the spinning cup assembly 1 will rotate inside the fixed tube 301 by contacting with the structure of the limiting groove 105 and the balls 302.

[0025] In summary, as Figures 1 to 4 shown, when the spinning cup for rotor spinning is in use, first, according to the use requirements, the counterweight 203 is installed in the assembly hole 202 opened on the surface of the fixed ring 201 by using the threaded connection structure, so as to ensure the stability of the spinning cup assembly 1 during high-speed rotation by using the whole counterweight structure 2;

[0026] During the rotation of the whole spinning cup assembly 1, as the cup body 101 rotates at a high speed, the resulting centrifugal force expels the air in the cup outward. According to the principle of fluid pressure, cotton fibers enter the air flow cup and form a fiber flow, which continuously moves along the condensing groove 102 opened on the inner wall of the cup body 101, thus playing a twisting role. During the high-speed rotation process, impurities will be thrown out from the inside of the chip discharging hole 103;

[0027] During this process, the spinning cup assembly 1 will use the limiting groove 105 opened on the surface of the stabilizing shaft 104 and use the balls 302 installed on the inner wall surface of the fixed tube 301 as the limiting fulcrum. As the balls 302 roll inside the limiting groove 105, the stability of the rotation of the whole spinning cup assembly 1 can be ensured;

[0028] In addition, the exhaust hole 303, in cooperation with the hollow core shaft tube 4 and the core shaft hole 106, can provide a certain degree of ventilation and heat dissipation effect during the high-speed rotation of the spinning cup assembly 1, thereby reducing the heat generated by the friction between structures.

[0029] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
