Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a device for increasing the speed of a spinning frame. Background Art

[0002] The spinning frame is a key equipment used to process coarse yarn or semi-finished fiber (such as cotton strips, wool strips, etc.) into fine yarn (single yarn). It is generally responsible for stretching, twisting and winding the fiber raw materials, and finally forming fine yarn with a certain strength, twist and uniformity for use in subsequent processes such as winding, doubling, twisting, weaving, etc.

[0003] The core part of the ring spinning system of the spinning frame lies in the twisting and winding structure. The specific operation process of twisting and winding is as follows:

[0004] The yarn released from the jaws of the drafting roller is transferred to the wire ring through the precisely guided yarn guide hook. After the yarn passes through the wire ring on the steel collar, its end is connected to the rotating winding tube. The spindle drives the winding tube to rotate at high speed, and at the same time drives the winding section yarn to move. The yarn acts as a power source to pull the wire ring to slide smoothly along the surface of the steel collar, so that it can be wound and stored synchronously and efficiently during the twisting process.

[0005] At the same time, when the spindle drives the wire ring to complete a circumferential cycle, the corresponding balloon segment yarn also rotates one circle, during which the yarn forms a spiral winding in its own length direction (adding one twist). At this time, the balloon segment yarn expands outward into an annular balloon under the action of centrifugal force, which not only provides tension adjustment space, but also ensures the stability and quality consistency of the yarn twisting process by balancing the centrifugal force and twisting force.

[0006] However, when the spinning machine is actually running to perform the twisting and winding operation of the yarn, the yarn tension is often too large or fluctuates violently, resulting in frequent yarn breakage. This not only wastes raw materials, but also causes the machine to frequently stop for jointing, interrupting continuous production, thereby significantly reducing the machine speed and output.

[0007] To this end, the present application proposes a device for increasing the speed of a spinning frame to solve the above technical problems. Utility Model Content

[0008] The main purpose of the utility model is to provide a device for increasing the speed of a spinning frame, which can adjust the tension between the yarn and the wire ring and the tension of the spinning balloon, thereby avoiding a large number of yarn breakages when the spinning frame is running.

[0009] In order to solve the above technical problems, the utility model provides a device for increasing the speed of a spinning frame, which is arranged on a twisting and winding mechanism of the spinning frame, and comprises:

[0010] A steel collar body, on which a wire ring is movably arranged, and the wire ring is connected to the yarn of the spinning frame;

[0011] A collar plate, the collar body is movably placed inside the collar plate, and a plurality of sliding tracks are annularly distributed on the collar plate;

[0013] The high-pressure airflow jet device is arranged on the sliding base. The high-pressure airflow jet device is provided with a first nozzle for pushing the wire ring to rotate and move on the steel collar body to perform twisting and winding of the yarn.

[0014] Furthermore, a mesh grille is sleeved on the steel collar body, and a second nozzle is provided on the high-pressure airflow injection device, which is used for vortex to push the mesh grille and the steel collar body to move circumferentially at high speed.

[0015] Furthermore, the steel ring body is connected to the steel ring plate through a plurality of bearing bodies distributed in an annular manner.

[0016] Furthermore, an annular bearing sleeve is installed at the bottom of the collar plate, an embedded shaft sleeve is arranged inside the bearing sleeve, and the bearing sleeve and the embedded shaft sleeve cooperate with each other to install multiple groups of bearing bodies.

[0017] Furthermore, a high-strength magnet is also provided on the embedded shaft sleeve for driving the steel collar body to approach the steel collar plate.

[0018] Furthermore, a positioning screw hole is provided on the side wall of the sliding track, and the positioning assembly is arranged on the sliding base to cooperate with the positioning screw hole to fix the position of the sliding base.

[0019] Furthermore, the positioning assembly includes a groove body arranged at the bottom, a positioning screw that is threadedly rotated through the side wall of the sliding base and extends into the groove body, and an anti-slip rotation block arranged at one end of the positioning screw.

[0020] Furthermore, the groove body cooperates with the sliding track to control the sliding base to slide on the upper limit of the sliding track, and the other end of the positioning screw is threaded into the positioning screw hole to fix the position of the sliding base on the sliding track.

[0021] Furthermore, the positioning assembly also includes a limiting groove opened on the side wall of the groove body and a limiting ring block movably arranged in the limiting groove, and the limiting ring block is arranged in the middle of the positioning screw.

[0022] The beneficial effects of the utility model are embodied in:

[0024] 2. The utility model is positioned and installed on multiple sliding tracks through different sliding bases, and can conveniently adjust the installation positions of multiple high-pressure airflow injection devices on the steel collar plate.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] In the embodiment, see Figures 1 to 5 .

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, the utility model provides a device for increasing the speed of a spinning frame, which is arranged on a twisting and winding mechanism of the spinning frame and comprises:

[0037] A steel collar body 1, on which a wire ring 11 is movably arranged, and the wire ring 11 is connected to the yarn of the spinning frame;

[0038] A collar plate 2, a collar body 1 is movably placed inside the collar plate 2, and a plurality of sliding rails 21 are annularly distributed on the collar plate 2;

[0039] A plurality of sets of sliding bases 7 are positioned and installed on the sliding rails 21 through positioning components 8;

[0040] A high-pressure air flow injection device 9 is arranged on the sliding base 7. A first nozzle 91 is provided on the high-pressure air flow injection device 9, which is used to generate a high-pressure air flow to push the wire ring 11 to rotate and move on the steel collar body 1 to twist and wind the yarn. At this time, the wire ring 11 and the spinning air ring rotate synchronously, which can reduce the tension between the yarn and the wire ring 11.

[0041] At this time, the high-pressure airflow injection device 9 can adjust the injection air pressure of the first nozzle 91 through air pressure regulation, so as to facilitate the precise control of the tension of the spinning air circle to reduce the force on the yarn and keep a relatively stable tension state during the twisting and winding process, thereby significantly reducing the breakage caused by excessive tension and achieving improved production efficiency and output.

[0042] In the specific implementation, the sliding base 7 is first slid into the sliding track 21, and the positioning assembly 8 is used to fix the position of the sliding base 7 on the steel collar plate 2. At this time, the nozzle air pressure of the high-pressure airflow injection device 9 on the sliding base 7 is regulated by air pressure adjustment, and then the winding tube body is passed through and fixed on the inner side of the steel collar body 1. At this time, the yarn of the spinning machine passes through the steel wire ring 11 and is connected to the winding tube body. The high-pressure airflow injection device 9 is turned on to promote the synchronous rotation of the steel wire ring 11 and the spinning air ring through the high-pressure airflow, thereby increasing the twisting and winding speed of the yarn on the winding tube body. At this time, the intensity and direction of the high-pressure airflow of the first nozzle 91 can also be controlled to accurately adjust the influence of the cyclone vortex on the spinning air ring, thereby controlling the air ring tension and keeping it within an ideal range.

[0043] It should be noted that the high-pressure airflow injection device 9 is a prior art, and the high-pressure airflow injection structure in the prior art that can be adjusted by air pressure can be directly used, and the specific principle structure of the high-pressure airflow injection is not described in detail here.

[0044] The steel collar body 1 is sleeved with a mesh grille 12, and the high-pressure airflow injection device 9 is provided with a second nozzle 92, which is used for eddy current to push the mesh grille 12 and the steel collar body 1 to move in a circumferential direction at a high speed.

[0045] In the specific implementation, different sliding bases 7 are positioned and installed on multiple sliding rails 21, so that the installation positions of multiple high-pressure airflow injection devices 9 on the steel collar plate 2 can be conveniently adjusted. When the multiple high-pressure airflow injection devices 9 are evenly distributed in an annular shape, the second nozzle 92 driving the high-pressure airflow injection device 9 is turned on. The second nozzle 92 generates a high-pressure airflow, which can act on the mesh grid 12. After the mesh grid 12 guides or disperses the airflow, the torque generated prompts the mesh grid 12 to drive the steel collar body 1 to move in an annular direction at high speed, reducing the direct contact and friction between the steel collar body 1 and the wire ring 11, thereby reducing friction loss. At the same time, due to the reduction of friction loss, the energy utilization efficiency of the spinning frame is improved, so that a higher speed can be achieved under the same energy consumption. Moreover, due to the reduction of friction, the wear of the steel collar body 1 and the wire ring 11 is also reduced accordingly, which is conducive to maintaining a higher operating speed without premature performance degradation, extending the service life of the steel collar body 1 and the wire ring 11, and is conducive to the long-term and stable use of the twisting and winding mechanism of the spinning frame.

[0046] It should be noted that the inner side of the mesh grille 12 is closed, which can ensure that the high-pressure airflow vortex can efficiently drive the mesh grille 12 and the steel collar body 1 to move in a circumferential direction at high speed. At the same time, the annular distribution air nozzle generates high-pressure airflow vortex, which belongs to the prior art. And driving the internal object to rotate in a circular direction by the high-pressure airflow vortex is a common use method of the high-pressure airflow vortex. Therefore, its specific principle will not be elaborated here.

[0047] In one embodiment, if Figure 2 As shown, the ring body 1 is connected to the ring plate 2 via a plurality of bearing bodies 4 distributed in an annular manner.

[0048] It can be explained here that in the prior art, the steel collar body 1 is installed and fixed on the steel collar plate 2 during the operation of the twisting and winding mechanism of the traditional spinning machine. Therefore, the present application installs the steel collar body 1 originally fixed on the steel collar plate 2 through a bearing connection, so that it can rotate freely under the action of external force.

[0049] Furthermore, an annular bearing sleeve 3 is installed at the bottom of the collar plate 2 , an embedded shaft sleeve 5 is arranged inside the bearing sleeve 3 , and the bearing sleeve 3 and the embedded shaft sleeve 5 cooperate with each other to install multiple groups of bearing bodies 4 .

[0050] At the same time, the bearing sleeve 3 cooperates with the embedded shaft sleeve 5 to ensure that the bearing body 4 structure is protected while improving the overall load-bearing effect of the device.

[0051] It should also be noted that the bearing body 4 generally adopts a ball structure, that is, a movable ball that extends out of the lubricating sleeve is rolled in a lubricating sleeve connected to the steel collar plate 2, so that it can be connected to the steel collar body 1 through the ball. It should also be noted that the bearing body 4 here can also be replaced by other existing technical structures or bearing structures with the same effect.

[0052] Furthermore, a high-strength magnet 6 is also provided on the embedded shaft sleeve 5 for driving the steel collar body 1 to approach the steel collar plate 2, and the installation position of the high-strength magnet 6 needs to be able to ensure that the high-strength magnet 6 does not connect and react with the steel collar plate 2. At this time, the high-strength magnet 6 reacts with the steel collar body 1 to drive the steel collar body 1 to approach the steel collar plate 2.

[0053] Furthermore, in one embodiment, if Figure 3 and Figure 4 As shown, a positioning screw hole 22 is provided on the side wall of the sliding track 21 , and the positioning assembly 8 is arranged on the sliding base 7 to cooperate with the positioning screw hole 22 to fix the position of the sliding base 7 .

[0054] The positioning assembly 8 includes a groove body 81 arranged at the bottom, a positioning screw 82 that is threadedly rotated through the side wall of the sliding base 7 and extends into the groove body 81 , and an anti-slip rotating block 83 arranged at one end of the positioning screw 82 .

[0055] In a specific implementation, the groove body 81 cooperates with the sliding rail 21 to control the sliding base 7 to slide at the upper limit position on the sliding rail 21, and the other end of the positioning screw 82 is threaded into the positioning screw hole 22 to fix the position of the sliding base 7 on the sliding rail 21, thereby realizing the positioning installation of the high-pressure airflow injection device 9.

[0056] By setting the positioning component 8 here, the operator can quickly adjust the installation status of the sliding base 7 on the sliding rail 21, so that the high-pressure airflow injection device 9 on the steel collar plate 2 can be quickly and conveniently installed and disassembled, which is convenient for the installation, replacement and maintenance of the high-pressure airflow injection device 9. After the high-pressure airflow injection device 9 is disassembled, the steel collar body 1 can be quickly taken out to repair and replace the steel collar body 1, wire ring 11 and mesh grid 12, thereby extending the overall service life of the device and facilitating use.

[0057] In addition, it should be noted that the positioning assembly 8 also includes a limiting groove 85 opened on the side wall of the groove body 81 and a limiting ring block 84 movably arranged in the limiting groove 85 , and the limiting ring block 84 is arranged in the middle of the positioning screw 82 .

[0058] During specific use, since the limiting ring block 84 moves and limits in the limiting groove 85, combined with the anti-skid rotating block 83, during the positioning process, the positioning screw 82 is threaded out of the positioning screw hole 22 by rotating the anti-skid rotating block 83. When the positioning restriction of the sliding base 7 is cancelled, the limiting ring block 84 can prevent the positioning screw 82 from being threaded out of the sliding base 7.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0060] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0061] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, in the embodiments of the utility model, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
