Description

Technical Field

[0001] This invention relates to the field of ring spinning machine cleaning and maintenance technology, and more specifically, to a device for cleaning accumulated fibers in the negative pressure box of a ring spinning machine. Background Technology

[0002] In the compact spinning system of a ring spinning machine, the negative pressure box (negative pressure roller) is located at the rear of the spinning machine. The negative pressure box is the core component for achieving fiber aggregation. It relies on the internal negative pressure airflow to gather the drafted sliver, and after the yarn breaks, the fiber bundle at the front roller exit needs to be sucked away in time.

[0003] After the negative pressure roller of the spinning machine has been running continuously for a long time, a large amount of cotton wool, fly waste and other accumulated debris will accumulate inside the negative pressure box. The accumulation of debris will cause the air duct to be blocked and the negative pressure value to drop. At best, it will affect the yarn gathering effect, and at worst, it will trigger the negative pressure alarm of the equipment and cause the machine to stop.

[0004] Currently, the cleaning of accumulated debris in negative pressure chambers is generally done manually: that is, by operators manually removing and cleaning it. This method is labor-intensive, time-consuming, and results in extremely low cleaning efficiency. Moreover, manual removal is not thorough, and it is difficult to clean the accumulated debris in the corners and deep inside the chamber. In addition, the accumulated debris is easy to spread during manual removal, and the working environment is poor.

[0005] Therefore, it is necessary to provide a cleaning device for the negative pressure box of the spinning machine to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cleaning device for the accumulated cotton in the negative pressure box of a spinning machine to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A cleaning device for cleaning accumulated fibers in the negative pressure chamber of a spinning frame, used to clean accumulated fibers inside the negative pressure chamber of a spinning frame, including: A connecting frame is provided with an adsorption mechanism for adsorbing the connecting frame into the cleaning port area of ​​the negative pressure box. An adapter tube is provided on the connecting frame. The two ends of the adapter tube are respectively detachably connected to a suction tube and a cleaning tube that are interconnected. Both the suction tube and the cleaning tube are telescopic hoses. The other end of the suction tube is connected to the cotton suction pipe in the workshop, and the other end of the cleaning tube extends into the cleaning port. A traction mechanism, connected to the connecting frame, is used to move and swing the cleaning tube within the cleaning port.

[0008] Furthermore, the traction mechanism includes: The frame has horizontal axes rotatably connected to both its left and right ends, and the other end of the horizontal axes is connected to the inner wall of the connecting frame. A sleeve is disposed within the swing frame, and a movable rod is slidably inserted into the middle of the sleeve, one end of which is connected to the cleaning tube.

[0009] Furthermore, the upper and lower walls of the sleeve are provided with vertical shafts, the other end of which is rotatably connected to the inner wall of the swing frame, and the vertical shaft and the horizontal shaft are perpendicular to each other in space.

[0010] Furthermore, both the horizontal axis and the vertical axis are provided with sleeve blocks, and the outer wall of the sleeve blocks is provided with multiple limiting holes. The swing frame is provided with two limiting components, which are used to limit the vertical swing of the swing frame and the horizontal swing of the vertical axis, respectively.

[0011] Furthermore, the limiting component includes: A support plate is provided on the swing frame, and a screw is threadedly connected to the support plate. The end of the screw is provided with a limiting block that matches the limiting hole.

[0012] Furthermore, the outer wall of the cleaning tube is detachably provided with two symmetrical clamps, which are fixed by fasteners, and one of the clamps is connected to the moving rod.

[0013] Furthermore, a U-shaped block is installed at one end of the movable rod, and a rotating rod is rotatably connected to the left and right walls of the U-shaped block. A connecting rod that is detachably connected to the hoop plate is provided on the rotating rod.

[0014] Furthermore, one of the hoop plates has a stud on its outer wall, and the end of the rotating rod is rotatably connected to a sleeve rod that is threadedly connected to the stud.

[0015] Furthermore, the adsorption mechanism includes: Multiple fixing plates are disposed on the outer wall of the connecting frame, and a suction cup is installed at one end of each fixing plate.

[0016] Furthermore, the outer wall of the connecting frame is provided with an air pipe, and the air pipe is connected to a negative pressure connector and multiple connecting pipes, each of which is connected to the suction cup.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention relies on the negative pressure of the existing cotton suction pipe in the workshop. The cleaning pipe and suction pipe of this cleaning device suck the accumulated cotton lint, fly lint and other accumulated flowers in the negative pressure box into the cotton suction pipe. It will not spread into the workshop environment during the cleaning process, effectively improving the working environment. Moreover, it completely replaces the manual removal of accumulated flowers, greatly reducing the labor intensity of operators and significantly shortening the cleaning time.

[0018] 2. This invention enables the cleaning tube to move in multiple degrees of freedom through a traction mechanism, including three-dimensional spatial adjustment of the cleaning tube's forward and backward extension, up and down swing, and left and right swing. This allows the opening of the cleaning tube to cover every corner inside the negative pressure box, effectively solving the problems of incomplete cleaning by manual scooping and difficulty in cleaning accumulated flowers in deep corners. This significantly improves the cleaning effect and efficiency, and reduces negative pressure alarms and shutdown failures.

[0019] 3. The present invention adopts a combination structure of connecting frame and adsorption mechanism, which can quickly fix the whole device in the cleaning port area of ​​negative pressure box without additional drilling or fasteners. It is easy to install and disassemble, and the whole device has a simple structure and low cost. It can be put into use without large-scale modification of existing spinning machines and without structural modification of the negative pressure box body. It can be directly adapted to existing spinning machine equipment, and the installation and use threshold is low.

[0020] 4. This invention, through the cooperation of the sleeve block and the limiting component, can lock the swing frame and sleeve at a specific swing angle, so that the cleaning tube is kept at a certain fixed angle for cleaning operations. The swing angle of the cleaning tube can be flexibly adjusted and locked, so that the tube opening of the cleaning tube is always aligned with the area of ​​accumulated flowers, thereby improving the targeting and efficiency of cleaning.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-8 A cleaning device for cleaning accumulated fibers in the negative pressure box of a spinning machine, used to clean accumulated fibers in the negative pressure box 1 of the spinning machine, including: The connecting frame 2 is equipped with an adsorption mechanism 3, which is used to adsorb the connecting frame 2 onto the cleaning port 4 area of ​​the negative pressure box 1. When in use, the connecting frame 2 covers the outside of the cleaning port 4 and is fixed by adsorption mechanism 3. No need to modify the equipment by drilling, welding or other modifications. It is easy to disassemble and assemble and will not damage the body of the negative pressure box 1. The adapter tube 5 is set on the connecting frame 2. The adapter tube 5 has a hollow through structure. The two ends of the adapter tube 5 are detachably connected to the suction tube 6 and the cleaning tube 7, which are interconnected. The suction tube 6 and the cleaning tube 7 form a connected air passage through the internal cavity of the adapter tube 5. Both the suction tube 6 and the cleaning tube 7 are telescopic hoses with good bending and telescopic deformation capabilities, and can be flexibly deformed with the cleaning action. The other end of the suction tube 6 is connected to the cotton suction pipe in the workshop, and the suction power is provided by the negative pressure of the cotton suction system in the workshop. The other end of the cleaning tube 7 extends into the cleaning port 4, which serves as the direct suction end for accumulated cotton. The traction mechanism 8, connected to the connecting frame 2, is used to move and swing the cleaning tube 7 in the cleaning port 4.

[0025] In use, first align the connecting frame 2 with the cleaning port 4 of the negative pressure box 1, and then firmly fix the connecting frame 2 to the outer wall of the negative pressure box 1 through the adsorption mechanism 3. The suction pipe 6 is connected to the cotton suction pipe in the workshop, and the cleaning pipe 7 extends into the cleaning port 4. After the negative pressure of the cotton suction pipe in the workshop is turned on, the negative pressure is transmitted to the cleaning pipe 7 through the suction pipe 6 and the adapter 5, and suction is generated at the opening of the cleaning pipe 7. The operator drives the cleaning pipe 7 to move back and forth and swing left and right and up and down in the cleaning port 4 through the traction mechanism 8, so that the opening of the cleaning pipe 7 can reach the inner wall, corners and deep areas of the negative pressure box 1, and suck up the accumulated cotton lint, fly dander and other accumulated lint into the cleaning pipe 7. After passing through the adapter 5 and the suction pipe 6, it enters the cotton suction pipe in the workshop for unified collection and treatment. After cleaning is completed, release the fixed state of the adsorption mechanism 3, and the entire device can be removed from the negative pressure box 1 for storage or for cleaning the next negative pressure box 1.

[0026] The entire cleaning process requires no manual removal; accumulated cotton is directly sucked into the workshop's suction pipe, preventing it from spreading into the workshop environment and effectively improving the working environment. It completely replaces the manual removal of accumulated cotton, significantly reducing the labor intensity of operators and shortening cleaning time. The traction mechanism 8 enables multi-degree-of-freedom movement of the cleaning pipe 7, allowing its opening to cover every corner inside the negative pressure box 1, effectively solving the problems of incomplete cleaning by manual removal and difficulty in cleaning deep corners, greatly improving cleaning effect and efficiency. The entire device has a simple structure and low cost, and can be put into use without large-scale modifications to existing spinning machines.

[0027] In addition, by adopting the combined structure of the connecting frame 2 and the adsorption mechanism 3, the entire device can be quickly fixed in the cleaning port 4 area of ​​the negative pressure box 1 without the need for additional drilling or fasteners. The installation and disassembly are convenient and do not require structural modification of the negative pressure box 1. It can be directly adapted to existing spinning machines and has a low threshold for installation and use.

[0028] The two ends of the adapter tube 5 are detachably connected to the suction tube 6 and the cleaning tube 7, respectively. They are flexible to disassemble and assemble, and different specifications of the tubes can be replaced according to the actual working conditions. Both the suction tube 6 and the cleaning tube 7 are telescopic hoses with good flexibility, which makes it easy for the traction mechanism 8 to drive the cleaning tube 7 to move and swing flexibly in the cleaning port 4, adapting to the complex spatial structure inside the negative pressure box 1.

[0029] For preferred options, please refer to [link / reference]. Figure 1-3 and Figure 6 The traction mechanism 8 includes: The swing frame 81 has horizontal shafts 82 rotatably connected to both its left and right ends. The other end of the horizontal shafts 82 is connected to the inner wall of the connecting frame 2. The two horizontal shafts 82 are arranged coaxially, and the swing frame 81 as a whole can swing up and down around the axis of the horizontal shafts 82. Sleeve 83 is located inside swing frame 81. A movable rod 84 is slidably inserted in the middle of sleeve 83. One end of movable rod 84 is connected to cleaning tube 7. Movable rod 84 can slide back and forth along the axis of sleeve 83.

[0030] In use, by pushing and pulling the moving rod 84, the cleaning tube 7 can be moved back and forth along the axis of the sleeve 83, realizing the feeding and retraction of the cleaning tube 7 in the cleaning port 4; the swing frame 81 can also be swung up and down around the axis of the horizontal axis 82, allowing the cleaning tube 7 to swing up and down in the cleaning port 4 and adjust its vertical angle. By adjusting the position of the cleaning tube 7, the accumulated flowers in different depth areas can be adsorbed and cleaned.

[0031] The traction mechanism 8, through the up-and-down swing of the swing frame 81 and the telescopic movement of the moving rod 84, enables the nozzle of the cleaning pipe 7 to move forward and backward and swing up and down within the cleaning port 4, effectively expanding the cleaning coverage area. The structure is simple and reliable, the operation is intuitive, and it is easy for operators to quickly master its use.

[0032] Furthermore, a handle 21 is provided at the other end of the moving rod 84. By holding the handle 21, the operator can push and pull the moving rod 84 to easily control the forward and backward movement and swing of the cleaning tube 7 in the cleaning port 4. The handle 21 makes the operation more labor-saving and comfortable, and also makes it easier for the operator to accurately control the moving distance and speed of the cleaning tube 7.

[0033] For preferred options, please refer to [link / reference]. Figure 1-3 and Figure 6 The upper and lower walls of the sleeve 83 are provided with vertical shafts 85. The other end of the vertical shaft 85 is rotatably connected to the inner wall of the swing frame 81. The vertical shaft 85 and the horizontal shaft 82 are perpendicular to each other in space.

[0034] Specifically, the sleeve 83 can reciprocate left and right around the vertical axis 85, thereby driving the moving rod 84 and the cleaning tube 7 to swing left and right in the cleaning port 4. The up-and-down swing achieved by the horizontal axis 82, the left-and-right swing achieved by the vertical axis 85, and the telescopic movement achieved by the moving rod 84 work together to give the cleaning tube 7 three degrees of freedom of movement in the cleaning port 4. It can reach any position inside the negative pressure box 1 and fully cover all areas inside the negative pressure box 1, especially the corners of the box and the deep parts of the air duct that are difficult to reach by man, which greatly improves the comprehensiveness and thoroughness of cleaning.

[0035] For preferred options, please refer to [link / reference]. Figure 2-4 and Figure 6 Both the horizontal axis 82 and the vertical axis 85 are provided with sleeve blocks 9. The outer wall of the sleeve block 9 is provided with multiple limiting holes 10. The swing frame 81 is provided with two limiting components 11, which are used to limit the up and down swing of the swing frame 81 and the left and right swing of the vertical axis 85, respectively.

[0036] With this design, once the cleaning tube 7 is adjusted to the target angle, the limiting component 11, in conjunction with different limiting holes 10, can lock the swing frame 81 and sleeve 83 at a specific swing angle, allowing the cleaning tube 7 to maintain a fixed posture for point cleaning. This prevents the tube from shaking randomly due to airflow during the cleaning process, thus improving the stability and accuracy of the cleaning process.

[0037] Operators can flexibly adjust the swing angle of the cleaning tube 7 and lock it according to the distribution of accumulated flowers inside the negative pressure box 1, so that the opening of the cleaning tube 7 is always aligned with the area where flowers accumulate, thereby improving the targeting and efficiency of cleaning. In addition, when storing and moving this cleaning device, the angle of the swing frame 81 and the sleeve 83 can be locked by the limiting component 11 to prevent it from shaking and causing collision damage.

[0038] For preferred options, please refer to [link / reference]. Figure 3-4 The limiting component 11 includes: A support plate 111 is mounted on the swing frame 81. A screw 112 is threaded onto the support plate 111. A limiting block 113 that matches the limiting hole 10 is provided at the end of the screw 112.

[0039] Specifically, when locking the angle, rotate the screw 112 to feed it along the threaded hole toward the sleeve 9, causing the end limit block 113 to move synchronously. Ultimately, the limit block 113 inserts into the corresponding limit hole 10, restricting the rotation of the sleeve 9 and thus locking the swing angle of the corresponding shaft. When adjusting the angle, rotate the screw 112 in the opposite direction to disengage the limit block 113 from the limit hole 10, thereby releasing the lock and allowing free adjustment of the swing angle. This structure is simple to operate, reliable in locking, requires no special tools, and allows for flexible switching between locked and unlocked states according to cleaning needs.

[0040] In this embodiment, please refer to Figure 2 , Figure 5 and Figure 8 The outer wall of the cleaning pipe 7 is detachably provided with two symmetrical clamps 12, which are fixed by fasteners. One of the clamps 12 is connected to the moving rod 84.

[0041] Specifically, the two clamps 12 clamp and fix the cleaning tube 7 by fasteners (such as bolts). When the moving rod 84 moves in and out of the sleeve 83 or swings with the sleeve 83, the cleaning tube 7 moves synchronously.

[0042] The clamp plate 12 adopts a detachable structure. The fasteners can be loosened as needed to remove the clamp plate 12 from the cleaning pipe 7, which facilitates the inspection, replacement or cleaning of the cleaning pipe 7. At the same time, different specifications of clamp plates 12 can be replaced according to the pipe diameter of the cleaning pipe 7, which has good adaptability.

[0043] Furthermore, fastening blocks 23 are provided at both ends of the clamping plate 12, and fastening holes 24 are provided on the fastening blocks 23. After the two clamping plates 12 are closed and tightly hug the cleaning pipe 7, the two clamping plates 12 can be fixed together by passing bolts through the fastening holes 24 and tightening nuts, thereby clamping and fixing the cleaning pipe 7. The tightening degree of the bolts can be adjusted according to the diameter of the cleaning pipe 7 to ensure a firm clamping while avoiding excessive compression and damage to the pipeline.

[0044] For preferred options, please refer to [link / reference]. Figure 2 and Figure 5-8 A U-shaped block 13 is installed at one end of the movable rod 84. The left and right walls of the U-shaped block 13 are rotatably connected to a rotating rod 14. A connecting rod 15 is provided on the rotating rod 14 and is detachably connected to the hoop plate 12.

[0045] This design allows the cleaning tube 7 to self-adaptively deflect at a certain angle relative to the moving rod 84 through the rotational cooperation of the rotating rod 14 and the U-shaped block 13. During the swinging and moving process of the cleaning tube 7, it can better adapt to the shape of the pipeline, avoid excessive bending of the pipeline causing air blockage, and further expand the range of motion of the cleaning tube 7, improve cleaning flexibility, and enable the tube opening of the cleaning tube 7 to be aligned with the flower accumulation area at a better angle, thereby improving the cleaning effect.

[0046] For preferred options, please refer to [link / reference]. Figure 2 and Figure 5-8 One of the hoop plates 12 has a stud 16 on its outer wall, and the end of the rotating rod 14 is rotatably connected to a sleeve rod 17 that is threaded to the stud 16.

[0047] With this design, when installing the cleaning tube, align the sleeve 17 with the stud 16 on the clamp plate 12, rotate the sleeve 17 to screw it into the stud 16, and the connection between the connecting rod 15 and the clamp plate 12 is completed. Disassembly is simple: unscrew the sleeve 17 in the opposite direction to separate the tube. The assembly and disassembly are very convenient, facilitating storage and relocation, and allowing for quick replacement of the cleaning tube 7 or maintenance of related components. The installation position of the cleaning tube can be finely adjusted by changing the screw-in depth, resulting in greater adaptability.

[0048] In this embodiment, please refer to Figure 1-2 and Figure 6 The adsorption mechanism 3 includes: Multiple fixing plates 31 are set on the outer wall of the connecting frame 2. A suction cup 32 is installed at one end of the fixing plate 31. The suction cup 32 can be made of flexible rubber or silicone material and can be tightly adsorbed on the flat outer wall of the negative pressure box 1.

[0049] With this design, during installation, the connecting frame 2 is pressed against the outer periphery of the cleaning port 4 of the negative pressure box 1, so that each suction cup 32 is tightly attached to the outer wall of the negative pressure box 1, and the air inside the suction cup 32 is expelled (by squeezing). The atmospheric pressure difference is then used to firmly attach the connecting frame 2 to the negative pressure box 1. The suction cup 32 adsorption and fixing method does not require any modification to the negative pressure box 1, will not damage the surface of the equipment, and can be completed in seconds, greatly improving the ease of use of the device and improving the overall work efficiency.

[0050] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 6 The outer wall of the connecting frame 2 is provided with an air pipe 18, and the air pipe 18 is connected to a negative pressure pipe 19 and multiple connecting pipes 20, and each connecting pipe 20 is connected to the suction cup 32.

[0051] With this design, the negative pressure connector 19 can be connected to an external negative pressure air source (such as an external air pump or workshop negative pressure pipeline). By drawing air through the negative pressure connector 19, a negative pressure environment can be simultaneously formed in the air pipe 18, all connecting pipes 20, and each suction cup 32, so that all suction cups 32 can generate uniform adsorption force at the same time, thereby firmly adsorbing the connecting frame 2 onto the outer wall of the negative pressure box 1, making it less likely to fall off during cleaning operations; when releasing the adsorption, disconnecting the negative pressure air source and allowing air to enter the pipeline can quickly and simultaneously release the adsorption state of all suction cups 32.

[0052] Compared to manually squeezing the suction cups 32, providing negative pressure uniformly through the negative pressure pipe 19 makes the adsorption force of each suction cup 32 more uniform and stable, and the adsorption reliability is higher. It is especially suitable for larger connecting frames 2 or heavier device structures.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 6 Both ends of the adapter tube 5 are provided with connecting rings 22. The connecting rings 22 are located at both ends of the adapter tube 5 and are used to detachably connect to the suction tube 6 and the cleaning tube 7 respectively. The connecting rings 22 can be connected by clamps, hose clamps or quick-connects to realize the quick installation and removal of the suction tube 6 and the cleaning tube 7, which facilitates the replacement and maintenance of the pipeline.
