Description

Technical Field

[0001] The present application relates to the technical field of ring spinning frames, and in particular to a ring spinning frame. Background Art

[0002] During the ring spinning process, the high-speed drafting and twisting of fibers produces a large amount of fly and lint. If these fly and lint are not promptly removed, they not only affect yarn quality but also pollute the working environment and endanger the health of operators. Existing technology removes these fly and lint by installing a suction tube below the rollers.

[0003] The cotton suction tube is usually connected to a fan or other exhaust device. When the fan is started, a certain negative pressure will be formed inside the cotton suction tube. Under the action of negative pressure, suction will be generated at the suction port of the cotton suction tube, and the flying cotton and short fibers will be sucked into the cotton suction tube under the action of suction. The flying cotton, short fibers and other impurities sucked into the cotton suction tube will move toward the direction of the connected fan along with the airflow.

[0004] The suction port of the cotton suction tube is a fixed hole. When the suction force of the cotton suction tube changes, the suction port cannot be adjusted, which causes the suction port to be blocked. For example, when the suction force of the suction port increases, more flying cotton and short fluff will be sucked out, but since the suction port is still the original size, it is easy to cause the suction port to be blocked. Utility Model Content

[0005] The purpose of the present application is to provide a ring spinning machine, which solves the problem that the suction opening size of the cotton suction tube cannot be automatically adjusted.

[0006] A ring spinning machine provided in the present application adopts the following technical solution: it includes a machine body, a cotton suction tube installed on the machine body, and a roller arranged on the machine body, the cotton suction tube is located below the roller, the cotton suction tube includes a cotton suction head, and a transport pipe connected to the cotton suction head, a cotton suction cavity connected to the transport pipe is provided in the cotton suction head, the cotton suction head is provided with a plurality of cotton suction holes connected to the cotton suction cavity, an elastic ring is provided in the cotton suction hole, and the cotton suction hole is provided with an adjustment component for automatically adjusting the size of the elastic ring, and the transport pipe provides suction to the cotton suction hole through an external air pump.

[0007] By employing this technical solution, the adjustment assembly can adjust the size of the elastic ring, thereby directly affecting the fly waste absorption flux. When the elastic ring becomes larger, the effective diameter of the cotton suction holes increases, increasing the area through which airflow passes, potentially increasing the fly waste absorption flux—that is, absorbing more fly waste per unit time. Conversely, when the elastic ring becomes smaller, the diameter of the cotton suction holes decreases, restricting airflow to a certain extent and correspondingly reducing the fly waste absorption flux.

[0008] Optionally, the adjustment component includes an elastic component arranged between the cotton suction hole and the elastic ring, the elastic component is fixedly connected to the cotton suction hole and the elastic ring respectively, and the deformation direction of the elastic component is along the radial direction of the cotton suction hole.

[0009] By adopting the above technical solution, the elastic component primarily serves as a positioning and support mechanism. It ensures the stable position of the elastic ring while also providing a connection and support point for the elastic ring. Under normal circumstances, the elastic component maintains a specific shape and position, allowing the cotton suction hole to perform its suction operation stably. When the suction force increases: When the suction force increases, the airflow pressure increases, and the force acting on the elastic ring also increases accordingly. At this time, the elastic ring expands and deforms outward to accommodate the greater airflow. During this process, the axis of the elastic ring shifts due to the uneven pressure. As the shape and position of the elastic ring change, the effective aperture of the cotton suction hole also increases accordingly, thereby increasing the fly cotton throughput.

[0010] When suction decreases: When suction decreases, the force acting on the elastic ring decreases. The elastic ring and the elastic component gradually recover their shape due to their own elasticity. As the elastic component recovers, the axis of the elastic ring returns to its original position, the aperture of the cotton suction hole returns to its initial state, and the cotton fly flux is adjusted back to an appropriate level accordingly.

[0011] Optionally, the ends of the elastic rings are provided with clamping parts, the elastic rings are installed in the cotton suction holes through the clamping parts, and the clamping parts limit the deformation direction of the elastic rings.

[0012] By adopting the above technical solution, the clamping part, on the one hand, fixes the elastic ring in the cotton suction hole, and on the other hand, limits the direction of deformation of the elastic ring. Since the deformation direction is clearly defined, when the suction changes, the elastic ring responds more consistently and can more accurately adjust its own size according to the size of the airflow, thereby achieving precise control of the flying flower flux. Secondly, the deformation direction along the radial direction of the cotton suction hole has a certain correlation with the flow direction of the airflow, which can better adapt to changes in the airflow. When the suction increases, the airflow mainly flows along the axial direction of the cotton suction hole, and the radial deformation of the elastic ring can more effectively adjust the aperture size to adapt to the increased airflow and flying flower flux requirements. When the suction decreases, the elastic ring restores its shape radially and can also be quickly adjusted to a suitable aperture.

[0013] Optionally, the elastic component is hollow, and a corrugated portion is provided at the end of the elastic component.

[0014] By adopting this technical solution, the hollow structure can, to a certain extent, increase the elastic deformation capacity of the elastic component. When subjected to external forces, the hollow portion can deform more easily, allowing the elastic component to better adapt to varying suction forces and more sensitively adjust the size of the elastic ring. The corrugated portion acts as a buffer and disperses stress, making the elastic component's deformation more uniform.

[0015] Optionally, both ends of the cotton suction hole have circular openings that gradually shrink from large diameter to small diameter circular openings, the small diameter circular opening of the cotton suction hole is connected to the cotton suction cavity, the angle between the inner side surface and the inner bottom surface of the elastic ring is a degree, one end gradually shrinks toward the other end, and the small end of the elastic ring is connected to the cotton suction cavity.

[0016] By adopting the above technical solution, the cotton suction hole and the elastic ring are designed in an expanded shape, and the end with a larger diameter can better capture the surrounding flying cotton, thereby increasing the range and efficiency of cotton suction; the existence of the elastic ring angle enables the elastic ring to be subjected to airflow pressure. The airflow pressure can act on the side wall of the elastic ring, allowing the elastic ring to expand outward.

[0017] Optionally, the body is fixedly connected to a fixing rod, the transport pipeline is arranged on the fixing rod, the transport pipeline includes a plurality of first pipelines, and a second pipeline spliced with the first pipeline, the first pipeline and the second pipeline are spliced at intervals, and the end of the second pipeline is provided with a splicing assembly connected to the first pipeline, a clamping block is installed on the fixing rod, the clamping block is fixed to the fixing rod by bolts, the clamping block is fixedly connected to a connecting plate, the connecting plate is connected to the first pipeline / second pipeline, the splicing assembly includes annular grooves arranged at both ends of the second pipeline, and a ring sleeved on the annular groove, the annular groove limits the movement distance of the ring.

[0018] By adopting the above technical solution, the pipeline is first assembled using a splicing method. During maintenance, when a section of the transport pipeline is damaged or malfunctions, the splicing structure allows the problematic section of the pipeline to be quickly located and removed for repair or replacement, eliminating the need to replace the entire pipeline. This significantly reduces maintenance costs and time. Secondly, when it comes to replacement, if the transport pipeline needs to be upgraded or replaced with pipes of different specifications, the splicing design allows for easy removal of the old pipe and installation of the new section, improving the efficiency and flexibility of replacement. Splicing assemblies also play an important role in repair and replacement. When a pipeline section needs to be repaired or replaced, the splicing assembly can quickly separate adjacent sections, facilitating operation. The first and second pipelines are mounted on a fixed rod to prevent interference with other pipelines during replacement.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The area of the flying fluid in the cotton suction hole is related to the suction force of the cotton suction hole. The airflow pressure can act on the side wall of the elastic ring. When the suction force of the cotton suction hole increases, the elastic ring is prompted to expand outward when subjected to the airflow pressure, thereby increasing the aperture of the cotton suction hole and further improving the cotton suction efficiency.

[0021] The transport pipeline is assembled using a splicing method, which greatly facilitates maintenance work. If a section of the transport pipeline is damaged or fails, the problematic section can be quickly located and removed for repair or replacement, eliminating the need to replace the entire transport pipeline. This significantly reduces maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0030] The embodiment of the present application discloses a ring spinning frame.

[0031] Reference Figure 1A machine body 1 with a cotton suction tube 2 includes a machine body 1, a cotton suction tube 2 mounted on the machine body 1, and a roller 3 disposed on the machine body 1. The cotton suction tube 2 is located below the roller 3. During the spinning process, flying fibers and impurities are mainly generated near the roller 3. Positioning the cotton suction tube 2 below the roller 3 can more directly capture these flying fibers and impurities. When the flying fibers and impurities fall under the action of gravity, the cotton suction tube 2 can promptly suck them in, preventing the flying fibers and impurities from accumulating around the roller 3 and affecting the spinning quality and the normal operation of the machine.

[0032] refer to Figure 2 The cotton suction tube 2 includes a cotton suction head 21 and a transport pipe 22 connected to the cotton suction head 21. In this embodiment, the shape of the cotton suction head 21 is a plate shape, and can also be a barrel shape. The plate shape can increase the area for absorbing flying cotton. A cotton suction cavity 211 connected to the transport pipe 22 is provided in the cotton suction head 21. A cotton suction hole 212 connected to the cotton suction cavity 211 is provided on the surface of the cotton suction head 21. The edge of the cotton suction hole 212 gradually shrinks inward from the end of the cotton suction cavity 211 and extends to the transport pipe in a smooth curve. The cotton suction hole 212 is provided with an elastic ring 214, and the cotton suction hole 212 is provided with an adjustment component 215 for automatically adjusting the size of the elastic ring 214. The elastic ring 214 can hinder the airflow from the cotton suction hole 212. The size of the elastic ring 214 can be changed according to the change of the airflow size through the adjustment component 215. The transport pipe 22 provides suction to the cotton suction hole 212 through an external air pump.

[0033] refer to Figure 3 and Figure 4 The adjusting component 215 includes an elastic component 213 arranged between the cotton suction hole 212 and the elastic ring 214. The elastic component 213 is usually made of a material with elastic deformation ability, such as rubber, silicone and other elastic materials. The elastic component 213 is fixedly connected to the cotton suction hole 212 and the elastic ring 214 respectively, providing positioning support for the elastic ring 214 to ensure that the position of the elastic ring 214 in the cotton suction hole 212 is stable; in this embodiment, the material of the elastic component 213 is rubber as an example. The elastic component 213 is a rotating body with a hollow structure, and a corrugated portion 2131 is provided at the end of the elastic component 213, which further enhances the elastic deformation ability of the elastic component 213, so that it can better adapt to different suction changes and deform more sensitively; the deformation force applied by the elastic component 213 to the elastic ring 214 is radially toward the cotton suction hole 212, so that when the elastic component 213 recovers its deformation, the deformation force will drive the elastic ring 214 to move toward the middle.

[0034] refer to Figure 4, the two ends of the cotton suction hole 212 have a circular opening with a large diameter gradually shrinking to a circular opening with a small diameter, and the small diameter circular opening of the cotton suction hole 212 is connected to the cotton suction cavity 211. This gradual expansion design improves the absorption efficiency of flying cotton; the elastic ring 214 is a rectangular rotating body, and the angle between the inner side surface and the inner bottom surface of the elastic ring 214 is 20-40 degrees. One end gradually shrinks toward the other end, and the small end of the elastic ring 214 is connected to the cotton suction cavity 211. The airflow enters from the larger end of the elastic ring 214, and the airflow enters from the larger end of the elastic ring 214. The flow channel gradually decreases, and the airflow exerts an outward deformation force on the interior, so that the elastic ring 214 can expand outward, thereby changing the flow area; the ends of the elastic ring 214 are provided with a clamping portion 2141, and the elastic ring 214 is installed in the cotton suction hole 212 through the clamping portion 2141, and the clamping portion 2141 limits the deformation direction of the elastic ring 214. The clamping portions 2141 at both ends limit the moving direction of the elastic ring 214, preventing the elastic ring 214 from axially offsetting along the cotton suction hole 212.

[0035] refer to Figure 5 and Figure 6 In order to facilitate maintenance and cleaning of the transport pipeline 22, the transport pipeline 22 is changed to a detachable splicing design. The transport pipeline 22 includes a plurality of first pipelines 222 and a second pipeline 221 spliced with the first pipeline 222. The first pipeline 222 and the second pipeline 221 are spliced at intervals. The end of the second pipeline 221 is provided with a splicing component connected to the first pipeline 222. The splicing component quickly realizes the splicing of the first pipeline 222 and the second pipeline 221. The splicing component includes an annular groove 2211 provided at both ends of the second pipeline 221 and a ring 2212 sleeved on the annular groove 2211. The annular groove 2211 limits the movement distance of the ring 2212. To increase the stability and firmness of the transport pipe 22, a fixing rod 11 is installed in the body 1, and the transport pipe 22 is arranged on the fixing rod 11. A clamping block 223 is installed on the fixing rod 11. The clamping block 223 includes a first clamping block 2231 and a second clamping block 2232. The first clamping block 2231 is fixedly connected to the connecting plate. The first clamping block 2231 and the second clamping block 2232 respectively abut against both sides of the fixing rod 11. The first clamping block 2231 and the second clamping block 2232 are fixedly installed on both sides of the fixing rod 11 by bolts and nuts. The clamping block 223 is fixedly connected to the connecting plate. The single connecting plate is fixedly connected to the first pipe 222 / the second pipe 221.

[0036] The implementation principle of the cotton suction tube 2 of the machine body 1 in the embodiment of the present application is as follows: under the action of the drafting and twisting of the roller 3, the yarn will produce flying fibers and short fibers, and the flying fibers and short fibers will fall onto the cotton suction head 21 below. The external air pump of the transport pipe 22 is started, so that the cotton suction holes 212 of the cotton suction head 21 generate suction, and the flying fibers and short fibers are sucked into the cotton suction cavity 211, and transported to the collection area through the transport pipe 22. When the production speed is accelerated and the flying fibers and short fibers increase sharply, the suction force of the cotton suction head 21 is increased by the air pump. Due to the increase in the suction force of the cotton suction head 21, more air flows through the cotton suction holes 212. When the air flow passes through the cotton suction holes 212, it will act on the elastic ring 214. When the air flow increases, the effect on the elastic ring 214 also increases, causing the elastic ring 214 to expand outward, thereby increasing the flow area of the flying fibers and short fibers, and preventing the flying fibers and short fibers from gathering near the cotton suction holes 212 and causing blockage.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
