Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a velvet sleeve type cleaning device for a drawing frame. Background Art

[0002] There are many types of cotton spinning drawing frames, such as single-eye, double-eye, and four-eye. The single-eye drawing frame feeds multiple slivers and makes one sliver after combining and drawing; the double-eye drawing frame outputs two slivers, and so on. The function of the drawing frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making the raw materials of different types or qualities mix evenly to achieve the specified mixing ratio.

[0003] The existing announcement number is CN215163403U, a drawing frame cleaning device, including a rotating roller, a cleaning velvet sleeve, and a suction pipe, the cleaning velvet sleeve is wound between two rotating rollers, and a suction port is provided on the suction pipe, and also includes a support roller, the two support rollers and the two rotating rollers form a quadrilateral, the cleaning velvet sleeve is wound around the supporting roller after passing through the supporting roller, the suction pipe is connected to a suction branch pipe, the suction branch pipe is provided with an elastic scraper, the elastic scraper is in contact with the part of the cleaning velvet sleeve where the supporting roller is located, and the suction branch pipe is provided with a secondary suction port, which is located below the elastic scraper. It can effectively remove the flying flowers and dust attached to the cleaning velvet sleeve, avoid contamination of the sliver after being contaminated by the roller, and ensure the quality of the sliver.

[0004] The above-mentioned existing scheme has the following problems: although the velvet sleeve can be continuously cleaned of flying flowers and dust by elastic scrapers and scraping teeth during continuous transmission of the velvet sleeve, when the velvet sleeve mainly absorbs the flying flowers and dust on the roller through the surface fluff material, the continuous contact of the elastic scraper and the scraping teeth on the fluff can easily cause the fluff to fall over, fall off, and become sparse, resulting in the loss of the cleaning effect on flying flowers and dust.

The first driving bevel gear is meshed with the first linkage bevel gear, and the second driving bevel gear is meshed with the second linkage bevel gear. The reversing gear is fixed at one end of the multi-directional screw in the axial direction. After the reversing gear moves forward and backward following the linkage plate, it can be meshed with the first linkage bevel gear and the second linkage bevel gear respectively.

The cleaning wool sleeve is made of a composite breathable material.

[0014] Preferably, the driving member includes a second connecting rod and a piston block. The linkage plate slides and drives the piston block to move in the second piston cavity and expand the fixing rod, so that the conveying roller moves away from the other set of conveying rollers.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the process of driving the wool sleeve to drive by the rotation of the conveying roller in the present invention, the air storage tank continuously performs cyclic air storage and high-pressure air jetting, and the wool sleeve can be blown from the inside to the outside every once in a while, replacing the long-term contact between the scraper and the wool sleeve, effectively removing the flying flowers and dust on the wool sleeve while avoiding the damage of the scraper to the wool sleeve, and improving the service life of the wool sleeve;

[0017] By setting the first rotating rod and the second rotating rod, and setting the inner side plate, the middle plate and the inner side plate, the inner side plate, the middle plate and the inner side plate are all slidably arranged at the bottom of the linkage plate. Through the sliding of the inner side plate, the middle plate and the inner side plate, the outer side plate, the middle plate and the second rotating rod can cooperate to realize the rapid movement of the piston plate, so that the high-pressure gas is ejected from the jet groove in the first piston cavity, and the wool sleeve can be cleaned more thoroughly. The cooperation of the middle plate, the inner side plate and the first rotating rod can realize the slow movement of the piston plate, so that the first piston cavity stably sucks air;

[0018] Through the cooperation of the piston block and the second piston cavity, after the piston block moves a stroke through the linkage plate, the fixing rod will be driven to move a certain distance by the pressure in the second piston cavity, and the bearing will drive the transmission roller on one side to move, causing a certain deformation of the cleaning wool sleeve and increasing the gap of the cleaning wool sleeve. When the transmission roller moves to drive the cleaning wool sleeve to reach the maximum deformation amount, the linkage plate moves in the reverse direction and drives the piston plate to compress the first piston cavity, so that the jet groove ejects high-pressure gas to blow the cleaning wool sleeve and remove the flying flowers and dust on the cleaning wool sleeve.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Please refer to Figures 1-7 , the present invention provides a technical solution:

[0031] Refer to Figures 1-3, A drawing frame flocked cleaning device, including two groups of conveying rollers 1 and a cleaning flocked sleeve 2 sleeved on the conveying rollers 1. An air storage tank 3 is arranged between the two groups of conveying rollers 1 on the inner side of the cleaning flocked sleeve 2. A jet groove 4 is arranged on the top of the air storage tank 3. A piston plate 5 is arranged in the air storage tank 3. A linkage plate 6 is slidably arranged on the air storage tank 3. Both ends of the linkage plate 6 in the length direction extend outside the air storage tank 3. First driving mechanisms 7 for driving the linkage plate 6 to slide along the sliver feeding direction are symmetrically arranged on both sides of the air storage tank 3. The first driving mechanism 7 includes a first rotating rod 71, a worm gear 72 and a worm 73. The worm 73 is coaxially arranged at both ends of the axial direction of the conveying roller 1. Fixed blocks 8 are symmetrically arranged on both sides of the air storage tank 3. The outer sides of the fixed blocks 8 are used for welding and fixing with the frame of the doubling machine. The first rotating rod 71 is rotatably arranged on the fixed blocks 8. Worm gears 72 are respectively fixedly arranged at both ends of the axial direction of the first rotating rod 71 and are respectively meshed and connected with the worms 73 arranged in the axial direction of the conveying roller 1. The first rotating rod 71 penetrates through the linkage plate 6 and is in threaded connection with the linkage plate 6. A first connecting rod 9 connected with the piston plate 5 is arranged at one end of the linkage plate 6. A first piston chamber 10 is formed on the side of the piston plate 5 away from the first connecting rod 9 in the air storage tank 3. The first driving mechanism 7 drives the piston plate 5 to move through the first connecting rod 9 so that the first piston chamber 10 sucks air; Second driving mechanisms 11 for driving the linkage plate 6 to move in the opposite direction of the sliver feeding are also arranged on both sides of the air storage tank 3. The second driving mechanism 11 drives the piston plate 5 to move through the first connecting rod 9 so that the gas in the first piston chamber 10 sprays from the jet groove 4 onto the flocked sleeve. It should be noted that: An air suction pipe is additionally arranged at the position of the cleaning flocked sleeve 2 opposite to the painting groove on the outer side. The air suction pipe sucks away the flying flower dust and debris that are easy to fall off on the surface of the flocked sleeve through an induced draft fan. After the flocked sleeve is used for a certain period, there will be flying flower dust and debris on the surface that are difficult to be sucked away by the air suction pipe. The high-pressure gas sprayed from the jet groove 4 can blow out the flying flower dust and debris that are difficult to fall off on the flocked sleeve, and then be sucked away by the air suction pipe. The air suction pipe is a conventional existing technology, so it will not be elaborated here. It should be noted that: The driving roller is rotatably arranged on the frame of the doubling machine. The rotation of the conveying roller 1 can be driven by the rotation of the motor 40 driving the worm 73 to rotate or other conventional driving methods.

[0032] See Figure 2 , 6, 7. To avoid the suction force on the velvet sleeve when the air storage box 3 stores air, an anti-suction plate 12 is provided at the position of the air storage box 3 corresponding to the jet groove 4. A plate groove 13 for the anti-suction plate 12 to slide is provided in the jet groove 4. One end of the plate groove 13 is provided with a pressing member 39 for driving the anti-suction plate 12 to block the jet groove 4. The pressing member 39 can be a compression spring. The bottom end face of the anti-suction plate 12 at the position of the jet groove 4 is provided with an inclined surface 38. A one-way valve 14 is provided on the side wall of the air storage box 3 corresponding to the first piston chamber 10. The one-way valve 14 only allows the first piston chamber 10 to suck external air. When the piston plate 5 compresses the first piston chamber 10, the air in the first piston chamber 10 will impact the inclined surface 38. After reaching a certain pressure, it will push the anti-suction plate 12 to slide, so that the high-pressure gas is ejected from the jet groove 4.

[0033] Refer to Figure 2 , 3 , the second driving mechanism 11 includes a second rotating rod 111. The second rotating rod 111 is rotatably arranged on the fixed block 8, and first gears 112 are respectively provided at both axial ends. Second gears 113 meshing with the first gears 112 are respectively provided at both axial ends of the first rotating rod 71. A spiral groove 15 is provided on the second rotating rod 111. The second connecting rod 361 penetrates through the linkage plate 6. A guide block 16 that forms a sliding fit with the spiral groove 15 is provided on the linkage plate 6. The second rotating rod 111 rotates and drives the linkage plate 6 to move in the opposite direction of the sliver feeding through the cooperation of the guide block 16 and the spiral groove 15. The cooperation of the guide block 16 and the spiral groove 15 can accelerate the speed of the piston plate 5 compressing the first piston chamber 10 and improve the jet pressure.

[0034] Refer to Figures 2-5, in order to ensure that the linkage plate 6 can reciprocate during the continuous non-reversing transmission of the conveying roller 1, reversing mechanisms 17 are provided at both ends of the linkage plate 6 outside the air storage tank 3. The reversing mechanism 17 includes an outer plate 171, an inner plate 173, and an intermediate plate 172. The outer plate 171, the inner plate 173, and the intermediate plate 172 are all slidably arranged at the bottom of the linkage plate 6. The reversing mechanism 17 further includes a multi-directional screw 174. The multi-directional screw 174 is rotatably arranged in the linkage plate 6. The multi-directional screw 174 penetrates through the outer plate 171, the inner plate 173, and the intermediate plate 172 and is respectively threadedly connected to the outer plate 171, the inner plate 173, and the intermediate plate 172. Among them, the thread helix direction on the multi-directional screw 174 is divided into three sections. The thread helix directions of the parts of the multi-directional screw 174 threadedly connected to the outer plate 171 and the inner plate 173 are the same, and the thread helix directions of the parts of the multi-directional screw 174 threadedly connected to the intermediate plate 172 and the outer plate 171 are opposite. When the multi-directional screw 174 rotates forward, it drives the intermediate plate 172 and the inner plate 173 to move towards the side close to each other, and drives the intermediate plate 172 and the outer plate 171 to move towards the side far from each other. When the multi-directional screw 174 rotates reversely, it drives the intermediate plate 172 and the inner plate 173 to move towards the side far from each other, and drives the intermediate plate 172 and the outer plate 171 to move towards the side close to each other. An outer rod port 18 adapted to the second rotating rod 111 is provided on the side of the outer plate 171 close to the intermediate plate 172. An inner rod port 19 adapted to the first rotating rod 71 is provided on the side of the inner plate 173 close to the intermediate plate 172. A first rod port 20 adapted to the second rotating rod 111 is provided on the side of the intermediate plate 172 close to the outer plate 171. The guide block 16 is arranged in the first rod port 20. A second rod port 21 is provided on the side of the intermediate plate 172 close to the inner plate 173. Internal threads adapted to threadedly connect to the first rotating rod 71 are provided on the inner walls of the second rod port 21 and the inner rod port 19. Through the above method, the piston plate 5 can be slowly moved to stably suck air into the first piston chamber 10, and the piston plate 5 can be quickly moved to achieve the effect of high-pressure jetting.

[0035] Refer to Figure 2 , 4, 5. To enable the outer plate 171, the inner plate 173 and the intermediate plate 172 to cooperate with each other and cycle with the first rotating rod 71 and the second rotating rod 111, a reversing assembly 22 for driving the multi-directional screw rod 174 to switch the rotation direction is provided on the air storage tank 3. The reversing assembly 22 includes a first power bevel gear 221, a first linkage bevel gear 222, a second power bevel gear 223, a second linkage bevel gear 224, and also includes a reversing gear 225. The first linkage bevel gear 222 and the second linkage bevel gear 224 are respectively rotatably arranged on the outer wall of the air storage tank 3 and are respectively located on the front and rear sides of the linkage plate 6. The first power bevel gear 221 and the second power bevel gear 223 are both fixed to the first rotating rod 71 and are respectively located on the front and rear sides of the linkage plate 6. The first power bevel gear 221 is meshed and connected with the first linkage bevel gear 222, and the second power bevel gear 223 is meshed and connected with the second linkage bevel gear 224. The reversing gear 225 is fixed to one end of the multi-directional screw rod 174 in the axial direction. After the reversing gear 225 moves back and forth with the linkage plate 6, it can be meshed with the first linkage bevel gear 222 and the second linkage bevel gear 224 respectively. It should be noted that: the conical surfaces of the first power bevel gear 221 and the second linkage bevel gear 224 are arranged oppositely. After the linkage plate 6 moves to make the reversing gear 225 contact the first linkage bevel gear 222, the reversing gear 225 will drive the multi-directional screw rod 174 to rotate forward. After the linkage plate 6 moves to make the reversing gear 225 contact the second linkage bevel gear 224, the reversing gear 225 will drive the multi-directional screw rod 174 to rotate reversely.

[0036] Refer to Figure 2 , 4, 5. To ensure the stability of the outer plate 171, the inner plate 173, and the middle plate 172 during their respective cooperation with the first rotating rod 71 or the second rotating rod 111 in the switching process, a sliding groove 23 is provided at the bottom of the linkage plate 6. Sliding plates 24 that are slidably connected to the sliding groove 23 are provided at the tops of the outer plate 171, the inner plate 173, and the middle plate 172. A plurality of limiting slots 25 are opened at the top of the sliding groove 23. A side extension plate 26 is provided on the side wall of the air storage tank 3. A plurality of limiting plates 27 are provided at positions corresponding to the limiting slots 25 at the bottom of the side extension plate 26. Limiting plate grooves 37 into which the limiting plates 27 can be inserted are provided on the sliding plates 24 at the tops of the outer plate 171, the inner plate 173, and the middle plate 172. When the multi-directional screw 174 rotates once, the outer plate 171, the inner plate 173, and the middle plate 172 slide to move the limiting plate groove 37 to a position opposite to another group of limiting plates 27. In this way, the outer plate 171 and the middle plate 172 can be stably cooperated with the second rotating rod 111, or the middle plate 172 and the inner plate 173 can be stably cooperated with the first rotating rod 71. It should be noted that: the length of the limiting plate 27 is slightly less than the maximum distance of a one-way stroke that the linkage plate 6 can move. After the reversing gear 225 meshes with the first linkage bevel gear 222 or the second linkage bevel gear 224 to drive the multi-directional screw 174 to rotate, the outer plate 171, the inner plate 173, and the middle plate 172 move and are smoothly cooperated with the first rotating rod 71 or the second rotating rod 111. Then, the reversing gear 225 disengages from the first linkage bevel gear 222 or the second linkage bevel gear 224, and the limiting plate groove 37 of the sliding plate 24 quickly enters the limiting plate 27. By this means, after the wire-changing gear disengages from the first linkage bevel gear 222 or the second linkage bevel gear 224, and after the outer plate 171 and the middle plate 172 are cooperated and are cooperated with the second rotating rod 111, the limiting plate groove 37 can quickly enter the limiting plate 27, or after the inner plate 173 and the middle plate 172 are cooperated and are cooperated with the first rotating rod 71, the limiting plate groove 37 can quickly enter the limiting plate 27.

[0037] Refer to Figures 2-5, in order to better separate the flying dust and debris on the cleaning flocked sleeve 2 by the high-pressure gas ejected from the paint spraying tank, an annular groove 28 is provided in the middle of the conveying roller 1 on the side of the linkage plate 6 away from the first connecting rod 9. A bearing 29 is sleeved on the annular groove 28. A fixing rod 30 is fixed on the outer wall of the outer ring of the bearing 29. A base block 31 is provided on the inner wall of the air storage tank 3 on the side of the linkage plate 6 away from the first connecting rod 9. A second piston cavity 32 for the fixing rod 30 to slide through is provided through the base block 31. A limiting groove 33 is provided on the inner wall of the second piston cavity 32. A pressing plate 35 which is slidably connected with the limiting groove 33 is provided on the outer wall of the fixing rod 30. A spring 34 which abuts against the pressing plate 35 is provided in the limiting groove 33. A driving member 36 for driving the fixing rod 30 to slide away from the piston plate 5 is provided on the linkage plate 6. The cleaning flocked sleeve 2 is made of a composite breathable material. For example, the cleaning flocked sleeve 2 adopts a microporous design and a flocking process. During the production process of the plastic material, through processing techniques such as adding a pore-forming agent during injection molding or adopting a special mold structure, tiny pores can be formed inside the material. These pores communicate with each other to form a breathable channel, enabling air to flow through the material. After the second piston cavity 32 is compressed by the piston block 362, the fixing rod 30 will drive the conveying roller to move a certain distance through the bearing 29, causing the cleaning flocked sleeve 2 to deform slightly, so that the high-pressure gas can pass through the gaps of the cleaning flocked sleeve 2, thereby effectively blowing away the flying flowers and debris.

[0038] Refer to Figure 4 , 5 , the driving member 36 includes a second connecting rod 361 and a piston block 362. The linkage plate 6 slides and drives the piston block 362 to move in the second piston cavity 32 and expand the fixing rod 30, so that the conveying roller 1 moves away from the other set of conveying rollers 1.

[0039] Please refer to Figures 1-7As shown, when the device is in use, the conveying roller 1 and the worm 73 rotate simultaneously. The rotation of the worm 73 drives the rotation of the worm wheel 72. The rotation of the worm wheel 72 drives the rotation of the first rotating rod 71. The rotation of the first rotating rod 71 will drive the linkage plate 6 to move in the direction of the sliver feeding through the threaded fit with the intermediate plate 172 and the inner side plate 173. The movement of the linkage plate 6 drives the piston plate 5 to move through the first connecting rod 9, causing the first piston chamber 10 to inhale air. During the process of the linkage plate 6 driving the piston plate 5 to move, the second connecting rod 361 will compress the second piston chamber 32. When the second piston chamber 32 is compressed to a certain extent, the fixed rod 30 will compress the spring 34 and drive the transmission roller to move away from the other transmission roller through the bearing 29, causing a certain deformation of the cleaning flocked sleeve 2 until the reversing gear 225 contacts the second linkage bevel gear 224. After the reversing gear 225 meshes with the linkage bevel gear, the reversing gear 225 will drive the multi-directional screw rod 174 to rotate, causing the inner side plate 173 and the intermediate plate 172 to move in opposite directions and disengage from the threaded connection with the first rotating rod 71. At the same time, the outer side plate 171 will move towards the intermediate plate 172 on the side close to each other, causing the outer side plate 171 and the intermediate plate 172 to cooperate with the second rotating rod 111. After the intermediate plate 172 and the outer side plate 171 cooperate with the second rotating rod 111, through the cooperation of the guide block 16 and the spiral groove 15, the linkage plate 6 will be quickly driven to move and the reversing gear 225 will disengage from the second linkage bevel gear 224. At the same time, the insertion plate will quickly insert into the limit plate groove 37 to ensure the stable cooperation of the intermediate plate 172, the outer side plate 171 and the second rotating rod 111. At this time, the rotation of the second rotating rod 111 will drive the linkage plate 6 to move in the direction opposite to the sliver feeding, so as to compress the first piston chamber 10 by the piston plate 5. After the pressure in the first piston chamber 10 increases, the anti-suction plate 12 will be driven to open through the inclined surface 38, so that the high-pressure gas will be ejected outward and the tightly adhered flying dust and debris will be blown off through the gaps of the cleaning flocked sleeve 2, and the flying dust and debris will be sucked away in cooperation with the external suction air pipe, so as to realize a thorough cleaning of the cleaning flocked sleeve 2 once in a cycle.

[0040] After the linkage plate 6 moves until the reversing gear 225 meshes with the first linkage bevel gear 222, the rotation of the multi-directional screw rod 174 will drive the intermediate plate 172 and the outer side plate 171 to slide in the direction away from each other. At the same time, the intermediate plate 172 and the inner side plate 173 move towards the side close to each other, causing the intermediate plate 172 and the inner side plate 173 to re-form a threaded connection with the first rotating rod 71. At this time, the reversing gear 225 disengages from the first linkage bevel gear 222. After the sliding plate 24 slides, the limit plate groove 37 is aligned and enters another limit plate 27, so as to drive the linkage plate 6 to move along the sliver feeding direction again through the cooperation of the intermediate plate 172, the inner side plate 173 and the first rotating rod 71, causing the first piston chamber 10 to inhale air again and prepare for the next cleaning of the cleaning flocked sleeve 2.
