Description

Technical Field

[0001] This application relates to the field of auxiliary component adjustment technology for spinning machines, and in particular to a device for spinning machines that facilitates the adjustment of the height of the yarn separator base. Background Technology

[0002] Inside the spinning frame, the yarn separator and the base are key auxiliary components that ensure stable yarn production. The yarn separator is usually vertically installed between adjacent spindles, and its core function is to form a physical barrier to block yarn interference when adjacent spindles are running, preventing yarn from tangling or colliding with each other. The base, as the load-bearing structure of the yarn separator, needs to provide stable support for the yarn separator to ensure that it remains in a stable position when the machine is running at high speed.

[0003] In actual operation, the existing connection structure between the yarn separator and the base has a design flaw: if the base position is fixed or inconvenient to adjust, the lower end of the yarn separator is easily higher than the surface of the ring, creating a gap. When a single spindle breaks, the high-speed spinning spindle causes a large amount of fly yarn to be generated from the broken yarn. This fly yarn can spread to the adjacent spindle area through the gap, thereby breaking adjacent normally operating yarns and causing a chain reaction of yarn breaks. This problem not only reduces production continuity but also increases operating costs due to frequent shutdowns to deal with yarn breaks, significantly affecting the efficient operation of the spinning frame. Therefore, a device for adjusting the height of the yarn separator base for spinning frames is provided. Utility Model Content

[0004] The purpose of this application is to provide a device for adjusting the height of the yarn separator base for a spinning frame, which has the characteristics of preventing yarn breakage of adjacent spindles, reducing chain breakage, and improving production continuity.

[0005] This application provides a device for adjusting the height of a yarn separator base on a spinning machine, which adopts the following technical solution: It includes a frame, a yarn separator body, a base body, and a height adjustment mechanism. The upper end of the yarn separator body is connected to the lower end of the base body. The base body is connected to the frame via the height adjustment mechanism. The height adjustment mechanism includes a first housing and a second housing. The upper ends of both the first and second housings are fixedly connected to the lower surface of the frame. A miniature forward and reverse motor is fixedly connected inside the first housing. A threaded column is fixedly connected to the upper end of the output shaft of the miniature forward and reverse motor. A rotating shaft is fixedly connected to the upper end of the threaded column. A bearing is fixedly connected to the upper surface inside the first housing. The upper end of the rotating shaft passes through the bearing. A threaded cap is threadedly connected to the surface of the threaded column. A first connecting rod is fixedly connected to the surface of the threaded cap. A first limiting groove is opened on the side of the first housing. The first connecting rod is movably connected inside the first limiting groove. The end of the first connecting rod away from the threaded cap is connected to the base body.

[0006] By adopting the above technical solution, and by setting up a height adjustment mechanism, a micro forward and reverse motor is used to drive the threaded column to rotate. With the transmission of the threaded cap and the first connecting rod, the height of the base body can be precisely adjusted, thereby driving the screen plate body to rise and fall to a position lower than the steel ring surface, effectively blocking the spread of flying flowers. The constraint of the first connecting rod by the first limiting groove and the cooperation between the bearing and the rotating shaft ensure that the adjustment process is stable and without shaking, solving the problem of fixed height or inconvenient adjustment in the original structure.

[0007] Preferably, a sliding rod is fixedly connected inside the second housing, a sliding cap is slidably connected to the surface of the sliding rod, a second connecting rod is fixedly connected to the surface of the sliding cap, a second limiting groove is opened on the side of the second housing, the second connecting rod is movably connected inside the second limiting groove, and the end of the second connecting rod away from the sliding cap is connected to the base body.

[0008] By adopting the above technical solution, the sliding rod and sliding cap in the second housing cooperate to provide additional guiding support for the base body. The cooperation between the second connecting rod and the second limiting groove further restricts the movement trajectory of the base body, preventing it from deviating or tilting during the lifting process. It works in synergy with the drive structure of the first housing to improve the overall stability of the adjustment.

[0009] Preferably, the screen plate body is fixedly connected to the base body by bolts, and the base body is fixedly connected to the first connecting rod and the second connecting rod by bolts, and the bolts are high-strength stainless steel bolts.

[0010] By adopting the above technical solution, high-strength stainless steel bolts are used to fix the yarn separator plate body to the base body and the base body to the connecting rod. This ensures the connection strength to adapt to the vibration environment of the high-speed operation of the spinning machine, while also having good corrosion resistance to prevent bolt corrosion caused by fly shavings. At the same time, the detachable design facilitates later maintenance and replacement.

[0011] Preferably, both the first and second housings are made of metal and have an anti-rust coating on their surfaces.

[0012] By adopting the above technical solution, the first and second housings are made of metal and have an anti-rust coating, which can provide rigid protection for the internal components, resist the impact of flying hair and mechanical collisions, and prevent dust and moisture in the working environment of the spinning machine from causing the housing to rust, thus extending the overall service life of the mechanism.

[0013] Preferably, both the slide bar and the threaded post are made of high-strength alloy material.

[0014] By adopting the above technical solution, the slide rod and threaded column are made of high-strength alloy material, which can withstand the gravity load of the base body and the mesh plate body and the torque force during the adjustment process, reduce deformation or wear after long-term use, and ensure the accuracy and stability of height adjustment.

[0015] Preferably, the bearing is a rolling bearing, and the inner ring of the bearing is interference-fitted with the shaft.

[0016] By adopting the above technical solution, the bearing is a rolling bearing and is interference-fitted with the shaft, which can reduce the frictional resistance when the threaded column rotates, reduce the energy consumption of the micro forward and reverse motor, and at the same time ensure the coaxiality of the shaft and the threaded column, avoiding adjustment jamming or component wear caused by shaking.

[0017] Preferably, both the first limiting groove and the second limiting groove are rectangular groove structures, and the groove walls are provided with a wear-resistant layer.

[0018] By adopting the above technical solution, the first limiting groove and the second limiting groove are designed as rectangular grooves with wear-resistant layers on the groove walls. This ensures the smooth directional sliding of the connecting rod in the grooves, reduces the wear of the groove walls caused by long-term friction, maintains the limiting accuracy, and extends the service life of the housing.

[0019] Preferably, the mesh separator body has a rectangular plate structure.

[0020] By adopting the above technical solution, the yarn separator plate body is designed as a rectangular plate structure. Its flat plate surface can form a continuous physical barrier, maximizing the blocking of yarn interference and fly waste diffusion between adjacent spindles. Moreover, the structure is simple and easy to mass-produce, and it is suitable for the spindle layout of different models of spinning machines.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This invention relates to a device for adjusting the height of a yarn separator base on a spinning frame. The device achieves precise height control through a height adjustment mechanism, preventing fly waste interference. A miniature forward and reverse motor drives a threaded column to rotate, causing a threaded cap to move up and down along the column, synchronously raising and lowering the first connecting rod and the base body. This ultimately achieves precise adjustment of the lower end height of the yarn separator body, ensuring it remains stably below the ring surface. This process overcomes the shortcomings of existing structures where "height is fixed or inconvenient to adjust." When a spindle breaks and fly waste occurs, the yarn separator body effectively blocks the fly waste from spreading through gaps, preventing yarn breakage in adjacent spindles, reducing chain breakage phenomena, and improving production continuity. The rotating shaft and bearing work together to improve adjustment stability and extend component life. The rotating shaft at the upper end of the threaded column passes through a bearing inside the first housing, with the bearing's inner ring and the rotating shaft having an interference fit. This structure reduces radial wobble and frictional loss during threaded column rotation, making the height adjustment process smoother. It also prevents a decrease in adjustment accuracy due to component wear, extending the service life of the height adjustment mechanism. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A device for adjusting the height of the yarn separator base for a spinning machine, referring to... Figure 1 , Figure 2 and Figure 3The system includes a frame 1, a screen plate body 2, a base body 3, and a height adjustment mechanism 4. The upper end of the screen plate body 2 is connected to the lower end of the base body 3. The base body 3 is connected to the frame 1 through the height adjustment mechanism 4. The height adjustment mechanism 4 includes a first housing 401 and a second housing 402. The upper ends of both the first housing 401 and the second housing 402 are fixedly connected to the lower surface of the frame 1. A miniature forward and reverse motor 403 is fixedly connected inside the first housing 401. A threaded post 404 is fixedly connected to the upper end of the output shaft of the miniature forward and reverse motor 403. A rotating shaft 405 is fixedly connected to the upper end of the threaded post 404. A bearing 406 is fixedly connected to the upper surface inside the first housing 401. The upper end of the rotating shaft 405 passes through the bearing 406. A threaded cap 407 is threaded onto the surface of the threaded post 404. A first connecting rod 408 is fixedly connected to the surface of the first housing 401. A first limiting groove 409 is provided on the side of the first housing 401. The first connecting rod 408 is movably connected inside the first limiting groove 409. The end of the first connecting rod 408 away from the threaded cap 407 is connected to the base body 3. By setting a height adjustment mechanism 4, the threaded column 404 is driven to rotate by a micro forward and reverse motor 403. With the transmission between the threaded cap 407 and the first connecting rod 408, the height of the base body 3 can be precisely adjusted, thereby driving the screen plate body 2 to rise and fall to a position lower than the surface of the steel collar, effectively blocking the spread of fly shavings. The constraint of the first connecting rod 408 by the first limiting groove 409 and the cooperation between the bearing 406 and the rotating shaft 405 ensure that the adjustment process is stable and without shaking, solving the problem of fixed height or inconvenient adjustment in the original structure.

[0032] Reference Figure 3 , Figure 4 and Figure 5A sliding rod 410 is fixedly connected inside the second housing 402. A sliding cap 411 is slidably connected to the surface of the sliding rod 410. A second connecting rod 412 is fixedly connected to the surface of the sliding cap 411. A second limiting groove 413 is provided on the side of the second housing 402. The second connecting rod 412 is movably connected inside the second limiting groove 413. The end of the second connecting rod 412 away from the sliding cap 411 is connected to the base body 3. The screen plate body 2 is fixedly connected to the base body 3 by bolts. The base body 3 is fixedly connected to the first connecting rod 408 and the second connecting rod 412 by bolts, and the bolts are high-strength stainless steel bolts. The 10, in conjunction with the sliding cap 411, provides additional guiding support for the base body 3. The cooperation between the second connecting rod 412 and the second limiting groove 413 further restricts the movement trajectory of the base body 3, preventing it from shifting or tilting during lifting. It works in synergy with the drive structure of the first housing 401 to improve the overall stability of adjustment. High-strength stainless steel bolts are used to fix the yarn separator plate body 2 to the base body 3 and the base body 3 to the connecting rod. This ensures the connection strength to adapt to the vibration environment of the high-speed operation of the spinning machine, while also having good corrosion resistance to prevent bolt corrosion caused by fly shavings. The detachable design also facilitates later maintenance and replacement.

[0033] Reference Figure 1 , Figure 2 and Figure 3 Both the first housing 401 and the second housing 402 are made of metal and have an anti-rust coating on their surfaces. The slide rod 410 and the threaded column 404 are made of high-strength alloy. The use of metal for the first housing 401 and the second housing 402 with an anti-rust coating provides rigid protection for the internal components, resisting the impact of flying cotton and mechanical collisions. It also prevents the housing from rusting due to dust and moisture in the working environment of the spinning machine, thus extending the overall service life of the mechanism. The slide rod 410 and the threaded column 404 are made of high-strength alloy, which can withstand the gravity load of the base body 3 and the yarn separator body 2 and the torque force during the adjustment process, reducing deformation or wear after long-term use and ensuring the accuracy and stability of height adjustment.

[0034] Reference Figure 1 , Figure 2 and Figure 3The bearing 406 is a rolling bearing 406, and the inner ring of the bearing 406 is interference-fitted with the rotating shaft 405. The first limiting groove 409 and the second limiting groove 413 are both rectangular groove structures, and the groove walls are provided with wear-resistant layers. The mesh plate body 2 is a rectangular plate structure. The bearing 406 is a rolling bearing 406 and is interference-fitted with the rotating shaft 405, which can reduce the frictional resistance when the threaded column 404 rotates, reduce the energy consumption of the micro forward and reverse motor 403, and at the same time ensure the coaxiality of the rotating shaft 405 and the threaded column 404, avoiding damage caused by shaking. To prevent adjustment jamming or component wear, the first limiting groove 409 and the second limiting groove 413 are designed as rectangular grooves with wear-resistant layers on the groove walls. This ensures the smooth directional sliding of the connecting rod in the grooves, reduces groove wall wear caused by long-term friction, maintains limiting accuracy, and extends the service life of the housing. The yarn separator plate body 2 is a rectangular plate structure. Its flat plate surface can form a continuous physical barrier, maximizing the blocking of yarn interference and fly waste diffusion between adjacent spindles. Moreover, the structure is simple and easy to mass-produce, adapting to the spindle layout of different models of spinning machines.

[0035] In this embodiment, precise height control is achieved through the height adjustment mechanism 4, blocking fly waste interference. The device drives the threaded column 404 to rotate through the micro forward and reverse motor 403, and the threaded cap 407 moves up and down along the threaded column 404, driving the first connecting rod 408 and the base body 3 to rise and fall synchronously, ultimately achieving precise adjustment of the lower end height of the partition plate body 2, which can be stably lower than the steel ring surface. This process solves the defects of the existing structure of "fixed height or inconvenient adjustment". When a single spindle breaks and produces fly waste, the partition plate body 2 can effectively block the fly waste from spreading through the gap, avoiding the yarn of adjacent spindles from being broken, reducing the chain breakage phenomenon, and improving production continuity. The rotating shaft 405 and the bearing 406 cooperate to improve adjustment stability and extend the service life of the components. The rotating shaft 405 at the upper end of the threaded column 404 passes through the bearing 406 in the first housing 401, and the inner ring of the bearing 406 is interference-fitted with the rotating shaft 405. This structure reduces radial wobble and frictional loss when the threaded column 404 rotates, making the height adjustment process smoother. At the same time, it avoids the decrease in adjustment accuracy due to component wear and extends the service life of the height adjustment mechanism 4.

[0036] The implementation principle of this application embodiment is as follows: The core function of the device is to drive the base body 3 and the partition plate body 2 to rise and fall through the height adjustment mechanism 4, thereby achieving precise control of the lower end height of the partition plate. The upper end of the partition plate body 2 is fixedly connected to the lower end of the base body 3. The base body 3 is connected to the threaded cap 407 and the sliding cap 411 in the height adjustment mechanism 4 through the first connecting rod 408 and the second connecting rod 412, respectively. The first housing 401 and the second housing 402 of the height adjustment mechanism 4 are fixed to the lower surface of the frame 1 to form an integral support structure. When the height needs to be adjusted, the micro forward and reverse motor 403 inside the first housing 401 is activated, and its output shaft drives the threaded column 404 to rotate. The rotating shaft 405 at the end rotates synchronously within the bearing 406. The bearing 406 ensures the stable rotation of the threaded column 404 through the interference fit between its inner ring and the rotating shaft 405. When the threaded column 404 rotates, the threaded cap 407 on its surface moves up and down along the thread direction, causing the first connecting rod 408 to move synchronously. The first connecting rod 408 slides within the first limiting groove 409 on the side of the first housing 401, which restricts its movement trajectory and prevents deviation. Simultaneously, the sliding cap 411 within the second housing 402 slides along the sliding rod 410, causing the second connecting rod 412 to move synchronously within the second limiting groove 413. Working in conjunction with the first connecting rod 408, it ensures that the base body 3 rises and falls smoothly without shaking. The base body 3 rises and falls with the movement of the first connecting rod 408 and the second connecting rod 412, thereby causing the partition plate body 2 to move synchronously, ultimately adjusting the lower end of the partition plate body 2 to a height lower than the surface of the steel collar. When a spindle of the spinning machine breaks off and produces fly waste, the yarn separator plate body 2 forms a complete physical barrier to prevent the fly waste from spreading to adjacent spindle areas and avoid a chain breakage phenomenon; high-strength stainless steel bolts ensure a firm connection between the yarn separator plate body 2 and the base body 3, and between the base body 3 and the connecting rod; the rust-proof coating of the first housing 401 and the second housing 402, and the high-strength alloy material of the slide rod 410 and the threaded column 404 enhance the durability of the device under complex working conditions; the wear-resistant layers of the first limiting groove 409 and the second limiting groove 413 reduce wear during long-term use and maintain adjustment accuracy.
