Description

Technical Field

[0001] The invention relates to the technical field of vinylon yarn production, in particular to a vinylon yarn roving machine which is convenient for adjusting tension. Background Art

[0002] The purpose of daily highway maintenance is to maintain the highway and the structures and facilities on the highway, maintain the highway performance as much as possible, restore the damaged parts in time, ensure safe, comfortable and smooth driving, and save transportation costs and time. At the same time, take correct technical measures to improve the quality of the project, extend the service life of the highway, and postpone the reconstruction time. During the daily maintenance of the highway, the staff needs to use a ditch cleaning device to clean the ditch of the highway. For example, the publication number "CN209098888U" proposes a roving machine, including a machine body with an opening on one side, a drafting device arranged on the machine body, and a twisting device arranged on the machine body. The machine body is provided with a chute, a slider is slidably arranged in the chute, and a mounting rod for installing raw materials is arranged on the slider, and a driving screw extending in the horizontal direction and threadedly connected to the slider is rotatably arranged on the machine body. By rotating the driving screw, the slider slides in the chute, so that the mounting rod is led out of the machine body, so that the raw materials are replaced outside the machine body, and the replacement of raw materials is convenient.

[0003] However, in the above scheme, as the twisting winder continuously winds the yarn drum, the diameter of the yarn drum gradually increases, causing the linear speed of the yarn to gradually increase during the winding process. Since the speed of the winder remains unchanged, the linear speed of the yarn will increase as the diameter of the yarn drum increases. Due to the faster delivery speed of the yarn, the residence time of the yarn in the twisting area is relatively shortened, and the twisting effect becomes worse, resulting in insufficient tension on the surface of the vinylon yarn, affecting the quality of the finished vinylon yarn. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a vinylon yarn roving machine that is easy to adjust the tension, which solves the problem in the prior art that as the twisting winder continuously winds the yarn tube, the diameter of the yarn tube gradually increases, resulting in the linear speed of the yarn gradually increasing during the winding process. Since the speed of the winder remains unchanged, the linear speed of the yarn will increase as the diameter of the yarn tube increases.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the diameter of the yarn tube on the surface of the winding roller gradually increases and the speed of the vinylon yarn becomes faster and faster, the staff controls the rotating column and the adjacent rotating sleeve to rotate in opposite directions, so that when the vinylon yarn passes between the first rotating frame and the second rotating frame, the first rotating frame and the second rotating frame rotate in opposite directions, so that before the vinylon yarn enters the winder and is twisted, the relative first protrusions can simultaneously perform false twist on the vinylon yarn from both sides, which can more effectively form alternating positive and reverse false twists on the vinylon yarn, increase the surface tension of the vinylon yarn, make the vinylon yarn more compact and stable, and increase the twisting effect on the vinylon yarn.

[0016] 2. The staff starts the second motor so that its output shaft drives the positioning shaft to rotate, and the rotating positioning shaft drives the third gear to rotate. Under the meshing action of the third gear and the corresponding second gear, the horizontal shaft drives the third bevel gear to rotate. Under the meshing action of the third bevel gear and the second bevel gear, the connecting column drives the turntable to rotate. When the positioning shaft rotates, the fifth bevel gear rotates with the positioning shaft, and the rotating fifth bevel gear meshes with the fourth bevel gear, so that the connecting column can drive the second pulley to rotate. Under the transmission action of the second belt, the third pulley drives the installation shaft to rotate. Under the meshing action of the sixth bevel gear and the seventh bevel gear, the rotating sleeve drives the second rotating frame to rotate. The rotation direction is opposite to that of the first rotating frame. No additional driving source is required to drive the rotation of the second rotating frame, thereby greatly increasing the power utilization rate.

[0017] 3. The staff starts the first electric push rod so that its output end drives the lifting plate and the first rotating frame to move up and down, thereby facilitating the staff to adjust the distance between the first rotating frame and the second rotating frame to adapt to the production of yarns of different specifications.

[0018] 4. By setting the first elliptical block and the second elliptical block, when the vinylon yarn moves, the sliding friction of the vinylon yarn is converted into rolling friction under the rotation of the first elliptical block and the second elliptical block, which greatly reduces the wear of the vinylon yarn. When the first rotating frame and the second rotating frame rotate, the first elliptical block and the second elliptical block are prevented from lateral rotation under the limiting action of the first arc groove and the second arc groove, thereby maintaining the stability of false twist. By setting the second protrusion and the third protrusion, the friction force generated by the first elliptical block and the second elliptical block when false twisting the vinylon yarn is increased, thereby enhancing the torsional effect.

[0019] 5. When the tension or thickness of the vinylon yarn changes, the slider can move along the slide groove, and the spring is deformed. The elastic effect of the deformed spring can enable the first rotating frame and the second rotating frame to always maintain appropriate contact pressure with the vinylon yarn, thereby ensuring a stable false twist effect.

[0020] 6. After the speed of the vinylon yarn increases, the tension of the vinylon yarn when it is transported between the adjacent first roller and the second roller is relatively large. At this time, the staff controls the output end of the second electric push rod to retract, so that the pressure wheel rises, thereby reducing the pressure between the pressure wheel and the vinylon yarn, thereby avoiding the situation where the vinylon yarn is broken due to excessive tension.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 17 As shown, a vinylon yarn roving machine that is easy to adjust tension, a conveying assembly 2 for conveying the vinylon yarn is provided on one side of the upper surface of the frame 1; An adjusting component 3 for adjusting the tension of the vinylon yarn is arranged on the other side of the upper surface of the frame 1. The adjusting component 3 includes a mounting frame 301, and the mounting frame 301 is fixedly mounted on the other side of the upper surface of the frame 1. A plurality of connection holes 4 are formed through the top surface of the frame 1, and a winder 402 with a twisting structure is rotatably mounted in each connection hole 4 through a first bearing 401. Electric guide rails 403 are provided on the sides of the frame 1 away from each other, and a lifting frame 404 is fixedly mounted on the moving ends of the two electric guide rails 403, and a plurality of winding rollers 405 are fixedly mounted on the upper surface of the lifting frame 404; The upper end of each winder 402 extends into the corresponding mounting frame 301 and is sleeved with a first bevel gear 5 . A driving assembly 6 for driving the winder 402 to rotate is disposed on one side of the mounting frame 301 .

[0025] Through the above technical scheme, the staff controls the operation of the conveying component 2 and the winder 402, so that the winder 402 rotates at a high speed and winds the vinylon yarn on the surface of the winding roller 405 after twisting. The diameter of the yarn tube on the surface of the winding roller 405 gradually increases, and the speed of the vinylon yarn becomes faster and faster. The staff starts the adjustment component 3 so that before the vinylon yarn enters the winder 402 and is twisted, the adjustment component 3 can perform false twist on the vinylon yarn, thereby increasing the surface tension of the vinylon yarn and improving the twisting effect on the vinylon yarn.

[0026] like Figure 3 , Figure 5 , Figure 6 , Fig. 9 , Fig.11 As shown, in this embodiment, the conveying assembly 2 includes a support frame 201, which is fixedly mounted on one side of the upper surface of the frame 1, and a plurality of rotating rods 202 are rotatably mounted between the inner walls of the support frame 201, and a plurality of first rotating rollers 203 are sleeved on the shaft of each rotating rod 202; One end of the shaft of the rotating rod 202 located in the middle passes through the support frame 201 and is sleeved with two first pulleys 204, and one end of the shaft of the rotating rod 202 located at both ends passes through the support frame 201 and is sleeved with a first pulley 204, and the adjacent first pulleys 204 are sleeved with a first belt 205; A first motor 206 is fixedly mounted on one side of the support frame 201, wherein a rotating rod 202 passes through the support frame 201 and is fixedly connected to an output shaft end of the first motor 206; A plurality of connecting rods 207 are rotatably installed between the inner walls of the support frame 201. The shaft of each connecting rod 207 is sleeved with a plurality of second rollers 208. The connecting rod 207 and one side of the shaft of the rotating rod 202 are sleeved with a first gear 209, and the two first gears 209 are meshed with each other.

[0027] The vinylon yarn passes between the adjacent first roller 203 and the second roller 208. When the vinylon yarn needs to be transported, the staff starts the first motor 206. Under the transmission action of the first pulley 204 and the first belt 205, each rotating rod 202 rotates. Under the meshing action of the two first gears 209, each connecting rod 207 rotates relative to the rotating rod 202, so that the adjacent first roller 203 and the second roller 208 rotate relative to each other, thereby transporting the vinylon yarn.

[0028] like Figure 5 , Fig.12 , Fig.16 As shown, it can be understood that in the present application, a lifting plate 302 is provided at one end of the mounting frame 301, and a plurality of circular holes 303 are formed through the upper surface of the lifting plate 302, and a rotating column 305 is rotatably mounted in each circular hole 303 through a second bearing 304, and a limiting hole 306 is formed on the lower end surface of each rotating column 305, and a sliding column 307 is provided in each limiting hole 306, and a rotating table 308 is fixedly mounted on the lower end of each sliding column 307, and a first rotating frame 309 is fixedly mounted on the lower surface of the rotating table 308; A plurality of positioning holes 310 are formed through the bottom surface of the mounting frame 301. A rotating sleeve 312 is rotatably mounted in each positioning hole 311 through a third bearing 311. A second rotating frame 313 is fixedly mounted on the inner wall of the rotating sleeve 312. A limiting groove 314 is formed on the upper surface of each rotating column 305; A plurality of first protrusions 315 are integrally formed on the surface of each first rotating frame 309 and the second rotating frame 313 .

[0029] The staff controls the rotating column 305 and the adjacent rotating sleeve 312 to rotate in opposite directions, so that when the vinylon yarn passes between the first rotating frame 309 and the second rotating frame 313, the first rotating frame 309 and the second rotating frame 313 rotate in opposite directions, so that the relative first protrusions 315 can simultaneously perform false twist on the vinylon yarn from both sides, which can more effectively form alternating positive and reverse false twist on the vinylon yarn, making the vinylon yarn more compact and stable.

[0030] like Figure 5 , Fig.12 As shown, it can be understood that in the present application, a plurality of cylinders 7 are rotatably mounted between the two sides of the inner wall of the mounting frame 301, and a second bevel gear 8 is sleeved on one side of the body of each cylinder 7, and a limit block 9 is fixedly mounted on the lower end of each cylinder 7 through the mounting frame 301, and each limit block 9 is respectively inserted and matched with the corresponding limit groove 314; A plurality of vertical plates 10 are fixedly installed between the inner walls of the mounting frame 301, and a horizontal shaft 11 is rotatably installed through one side of each vertical plate 10. A third bevel gear 12 is sleeved on one side of the shaft body of each horizontal shaft 11, and each third bevel gear 12 is meshed with the corresponding second bevel gear 8. A second gear 13 is sleeved on the other side of the shaft body of each horizontal shaft 11; A positioning shaft 14 is rotatably installed between the two sides of the inner wall of the mounting frame 301, and a plurality of third gears 1401 are sleeved on the shaft body of the positioning shaft 14, and each third gear 1401 is respectively meshed with the corresponding second gear 13. A second motor 15 is fixedly installed on one side of the mounting frame 301, and one end of the horizontal axis 11 passes through the mounting frame 301 and is fixedly connected to the output shaft end of the second motor 15.

[0031] The staff starts the second motor 15 so that its output shaft drives the positioning shaft 14 to rotate, and the rotating positioning shaft 14 drives the third gear 1401 to rotate. Under the meshing action of the third gear 1401 and the corresponding second gear 13, the horizontal shaft 11 drives the third bevel gear 12 to rotate, and under the meshing action of the third bevel gear 12 and the second bevel gear 8, the cylinder 7 drives the turntable 308 to rotate.

[0032] like Fig.12 , Fig.13 As shown, it can be understood that in the present application, a plurality of connecting columns 16 are rotatably mounted on one side of the inner wall of the mounting frame 301, a fourth bevel gear 17 is sleeved on one side of the column body of each connecting column 16, a plurality of fifth bevel gears 18 are sleeved on the shaft body of the positioning shaft 14, and each fifth bevel gear 18 is respectively meshed with the corresponding fourth bevel gear 17; A plurality of right-angle brackets 19 are fixedly mounted on one side of the inner wall of the mounting frame 301, and a mounting shaft 20 is rotatably mounted on one side of each right-angle bracket 19, and a sixth bevel gear 21 is sleeved on one side of the shaft body of each mounting shaft 20, and a seventh bevel gear 22 is sleeved on one side of the sleeve body of each rotating sleeve 312, and each sixth bevel gear 21 is respectively meshed with the corresponding seventh bevel gear 22; Each connecting column 16 is sleeved with a second pulley 23 , and each mounting shaft 20 is sleeved with a third pulley 24 on the other side of the shaft. The second belt 25 is sleeved on the surfaces of the adjacent third pulley 24 and the second pulley 23 .

[0033] When the positioning shaft 14 rotates, the fifth bevel gear 18 rotates along with the positioning shaft 14, and the rotating fifth bevel gear 18 meshes with the fourth bevel gear 17, so that the connecting column 16 can drive the second pulley 23 to rotate. Under the transmission action of the second belt 25, the third pulley 24 drives the mounting shaft 20 to rotate. Under the meshing action of the sixth bevel gear 21 and the seventh bevel gear 22, the rotating sleeve 312 drives the second rotating frame 313 to rotate. The rotation direction is opposite to that of the first rotating frame 309. No additional driving source is required to drive the rotation of the second rotating frame 313, which greatly increases the power utilization rate.

[0034] like Figure 6 , Fig.13 As shown, it can be understood that in the present application, a first electric push rod 26 is fixedly mounted on one side of the inner wall of the mounting frame 301, and the output end of the first electric push rod 26 passes through the mounting frame 301 and is fixedly connected to the lifting plate 302; Round rods 27 are slidably provided on both sides of the inner wall of the mounting frame 301 , and the lower end of each round rod 27 is fixedly connected to the lifting plate 302 .

[0035] The staff starts the first electric push rod 26 so that its output end drives the lifting plate 302 and the first rotating frame 309 to move up and down, thereby facilitating the staff to adjust the distance between the first rotating frame 309 and the second rotating frame 313 to adapt to the production of yarns of different specifications.

[0036] like Fig.16 As shown, it can be understood that in the present application, a first arc groove 28 is provided on the lower surface of each turntable 308 and the inner wall surface of the first rotating frame 309, and a first elliptical block 29 is rotatably installed in each adjacent first arc groove 28, and a second protrusion 30 is integrally provided on the surface of each first elliptical block 29; A second arc groove 31 is formed on the upper surface of each rotating sleeve 312 and the lower surface of the second rotating frame 313 . Second elliptical blocks 32 are rotatably mounted in adjacent second arc grooves 31 . A third protrusion 3201 is integrally formed on the surface of each second elliptical block 32 .

[0037] By setting the first elliptical block 29 and the second elliptical block 32, when the vinylon yarn moves, the sliding friction of the vinylon yarn is converted into rolling friction under the rotation of the first elliptical block 29 and the second elliptical block 32, which greatly reduces the wear of the vinylon yarn. When the first rotating frame 309 and the second rotating frame 313 rotate, the first elliptical block 29 and the second elliptical block 32 are prevented from lateral rotation under the limiting action of the first arc groove 28 and the second arc groove 31, thereby maintaining the stability of the false twist. By setting the second protrusion 30 and the third protrusion 3201, the friction force generated by the first elliptical block 29 and the second elliptical block 32 on the vinylon yarn during false twist is increased, thereby enhancing the torsional effect.

[0038] like Fig.16 As shown, it can be understood that in the present application, two slide grooves 33 are provided on the inner wall of each limiting hole 306, and a slider 34 is slidably arranged in each slide groove 33, and opposite sides of adjacent sliders 34 are respectively fixedly connected with corresponding slide posts 307; A slide bar 35 is fixedly installed between the two sides of the inner wall of each slide groove 33, and each slider 34 is slidably arranged on one side of the corresponding slide bar 35, and a spring 36 is sleeved on the other side of the slide bar 35.

[0039] When the tension or thickness of the vinylon yarn changes, the slider 34 can move along the slide groove 33, and the spring 36 is deformed. The elastic effect of the deformed spring 36 can enable the first rotating frame 309 and the second rotating frame 313 to always maintain appropriate contact pressure with the vinylon yarn, thereby ensuring a stable false twist effect.

[0040] like Figure 5 , Fig.14 As shown, it can be understood that in the present application, the driving assembly 6 includes a transmission shaft 601, which is rotatably mounted between two sides of the inner wall of the mounting frame 301, and a plurality of eighth bevel gears 602 are sleeved on the shaft body of the transmission shaft 601; A plurality of rectangular plates 603 are fixedly installed at the bottom of the mounting frame 301, and a transition shaft 604 is rotatably installed through one side of each rectangular plate 603. A ninth bevel gear 605 is sleeved on one side of the shaft of each transition shaft 604, and each ninth bevel gear 605 is meshed with the corresponding first bevel gear 5; A tenth bevel gear 606 is sleeved on the other side of each transition shaft 604, and each tenth bevel gear 606 is meshed with the corresponding eighth bevel gear 602; A third motor 607 is fixedly mounted on one side of the mounting frame 301 , and one end of the transmission shaft 601 passes through the mounting frame 301 and is fixedly connected to the output shaft end of the third motor 607 .

[0041] The staff starts the third motor 607 so that its output shaft drives the transmission shaft 601 to rotate, so that the eighth bevel gear 602 rotates along with the transmission shaft 601, and under the meshing action of the eighth bevel gear 602 and the tenth bevel gear 606, the transition shaft 604 drives the ninth bevel gear 605 to rotate, and under the meshing action of the ninth bevel gear 605 and the first bevel gear 5, the winder 402 rotates.

[0042] like Fig.15 As shown, it can be understood that in the present application, a second electric push rod 38 is fixedly mounted on the upper surface of the support frame 201 through a fixed frame 37, an output end of the second electric push rod 38 passes through the fixed frame 37 and is fixedly mounted with a moving frame 39, and a clamping wheel 40 is rotatably mounted between the two sides of the inner wall of the moving frame 39; Two lifting rods 41 are slidably provided through the top of the support frame 201 , and the lower ends of the two lifting rods 41 are fixedly connected to the moving frame 39 .

[0043] After the speed of the vinylon yarn increases, the tension of the vinylon yarn when transported between the adjacent first roller 203 and the second roller 208 is relatively large. At this time, the staff controls the output end of the second electric push rod 38 to retract, so that the pressure wheel 40 rises, thereby reducing the pressure between the pressure wheel 40 and the vinylon yarn, avoiding the situation where the vinylon yarn is broken due to excessive tension.

[0044] The working principle of this kind of vinylon yarn roving frame which is easy to adjust the tension: When in use, first, the staff controls the operation of the conveying component 2 and the winder 402, so that the winder 402 rotates at high speed and twists the vinylon yarn and then winds it on the surface of the winding roller 405. The diameter of the yarn tube on the surface of the winding roller 405 gradually increases, and the speed of the vinylon yarn becomes faster and faster. The staff starts the adjustment component 3 so that before the vinylon yarn enters the winder 402 and is twisted, the adjustment component 3 can perform false twist on the vinylon yarn, thereby increasing the surface tension of the vinylon yarn and improving the twisting effect on the vinylon yarn.

[0045] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
