Description

Technical Field

[0001] This utility model relates to the field of filament winding technology, and in particular to a high-efficiency winding machine. Background Technology

[0002] The crimping machine is one of the important pieces of equipment in polyester staple fiber production. Located between the preheating box and the yarn spreader, it processes the uniform thickness and tension of the straight yarn bundles fed from the lead into crimped fibers, giving them a certain cohesive force and improving their spinnability. The core part of the crimping machine is the crimping box, which consists of a pair of stacked crimping rollers and corresponding upper and lower crimping knives behind them. The sides of the knives are sealed with side plates.

[0003] Currently, the side plates of the HV741 type crimping machine are made of polytetrafluoroethylene (PTFE) plates, which are rectangular in shape. The pressure plate and the PTFE side plates are tightened with bolts. When the filament bundle forms its first curl at the clamping point of the upper and lower crimping rollers, it will expand to both sides, causing severe friction on the side plates.

[0004] The above-mentioned existing technical solutions have the following drawbacks: although the structure is simple, the side plate surface is easily worn and needs to be replaced regularly, otherwise the filament bundle will produce burrs, affecting the quality of the filament bundle, and the replacement requires stopping the machine, which will generate a lot of waste filaments. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency curling machine to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-efficiency curling machine includes a worktable and a curling box. The curling box is fixedly installed on the top of the worktable. The curling box includes a first curling roller, a second curling roller, a curling knife, and side plate units. The curling box has a structure where the top and front ends are not completely open. The first and second curling rollers are rotatably installed inside the curling box. The right ends of the first and second curling rollers pass through and extend to the outside of the right side of the curling box. The first curling roller is spaced apart at the top of the second curling roller. The curling knife is fixedly installed on the rear inner wall of the curling box and communicates with the outside of the curling box. The front end of the curling knife is aligned with the roller channel between the first and second curling rollers. Two side plate units are provided, and the two side plate units are symmetrically arranged about the front end of the curling knife.

[0008] The side plate unit includes a first servo motor, a cylinder, a gear set, a long side plate, and a copper side plate. The long side plate is disposed on one side of the coiling cutter. A receiving groove is provided on the front end of the long side plate near the coiling cutter. Four rotating shafts are rotatably mounted at equal intervals from front to back on the side of the long side plate away from the coiling cutter. The gear set is sleeved on the four rotating shafts. The copper side plate is rotatably mounted in the receiving groove. The front end of the copper side plate and the gear set are connected by transmission. The rear end of the first servo motor and the gear set are connected by transmission through a first coupling. The cylinder is disposed on the side of the gear set away from the long side plate.

[0009] By adopting the above technical solution, the two side plate units are symmetrically arranged about the curling knife. The curling knife points to the roller channel between the first and second curling rollers, ensuring that the filament can enter the roller channel through the curling knife. The curling work is completed with the cooperation of the first and second curling rollers. The first servo motor drives the gear set to rotate, thereby driving the copper side plate to rotate. The cylinder provides stable and adjustable lateral pressure to pressurize the copper side plate, thereby sealing the clamping points of the first and second curling rollers. This allows the first servo motor to drive the copper side plate to rotate. After the filament rubs against the copper side plate, the copper side plate will rotate at an angle, allowing the unrubbed surface of the copper side plate to rub against the filament further. This can extend the copper side plate replacement cycle, avoid the generation of a large amount of waste filament, and improve production efficiency.

[0010] In a further embodiment, the gear set includes a first gear, a second gear, a third gear, and a fourth gear, which are sequentially mounted on the left end of the rotating shaft from front to back. The first gear and the second gear mesh, the second gear and the third gear mesh, and the third gear and the fourth gear mesh. The number of teeth of the first gear, the second gear, the third gear, and the fourth gear decreases sequentially from front to back.

[0011] By adopting the above technical solution, since the fourth gear meshes with the third gear, the third gear meshes with the second gear, and the second gear meshes with the first gear, the fourth gear is driven to rotate by the first servo motor, which in turn drives the third gear, the second gear, and the first gear to rotate, ultimately achieving the purpose of the first gear driving the copper side plate to rotate.

[0012] In a further embodiment, the end of the rotating shaft passing through the first gear near the long side plate is detachably connected to the copper side plate, the end of the rotating shaft passing through the first gear away from the long side plate is fixedly connected to the movable part of the cylinder, and the end of the rotating shaft passing through the fourth gear away from the long side plate is connected to the output shaft of the first servo motor via a sprocket drive.

[0013] In a further embodiment, a conveying device is also included. The conveying device includes a second servo motor, a transmission box, a first universal joint, and a second universal joint. The transmission box includes a housing, a fifth gear, a sixth gear, a seventh gear, a first output shaft, a second output shaft, and a third input shaft. The left and right sides of the housing are each provided with a through-hole, a second hole, and a third hole. The first hole is spaced at the top of the second hole, and the third hole is spaced at the rear ends of the first and second holes. A second bearing is fixedly installed within each of the first, second, and third holes. Both ends of the first output shaft pass through and extend to the outside of the second bearing in the first hole. Both ends of the second output shaft pass through and extend to the outside of the second bearing in the second hole. Both ends of the third input shaft pass through and extend... The fifth gear is sleeved on the middle section of the first rotating rod, the sixth gear is sleeved on the middle section of the second universal joint, and the sixth gear is sleeved on the middle section of the third input shaft. The fifth, sixth, and seventh gears mesh with each other. The first universal joint is spaced at the top of the second universal joint. The first universal joint and the first winding roller are coaxially aligned. The left end of the first universal joint and the right end of the first winding roller are fixedly connected. The second universal joint and the second winding roller are coaxially aligned. The left end of the second universal joint and the right end of the second winding roller are fixedly connected. The right end of the first universal joint and the left end of the first output shaft are fixedly connected. The right end of the second universal joint and the left end of the second output shaft are fixedly connected. The right end of the input shaft is connected to the second servo motor via a second coupling.

[0014] In a further embodiment, the curling blade includes an upper curling blade and a lower curling blade, which form a curling channel. The upper curling blade is spaced apart at the top of the lower curling blade, and the upper and lower curling blades have the same width.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By symmetrically arranging two side plate units about the crimping blade, the crimping blade points towards the roller channel between the first and second crimping rollers, ensuring that the filament can enter the roller channel through the crimping blade. The crimping work is completed with the cooperation of the first and second crimping rollers. The first servo motor drives the gear set to rotate, thereby driving the copper side plate to rotate. The cylinder provides stable and adjustable lateral pressure to pressurize the copper side plate, thereby sealing the clamping points of the first and second crimping rollers. This allows the first servo motor to drive the copper side plate to rotate. After the filament rubs against the copper side plate, the copper side plate will rotate at an angle, allowing the unrubbed surface of the copper side plate to rub against the filament further. This can extend the copper side plate replacement cycle, avoid the generation of a large amount of waste filament, and improve production efficiency. Attached Figure Description

[0029] It also includes a transmission device 3, which comprises a second servo motor 31, a transmission box 32, a first universal joint 33, and a second universal joint 34. The transmission box 32 includes a housing 321, a fifth gear, a sixth gear, a seventh gear, a first output shaft 325, a second output shaft 326, and a third input shaft 327. The left and right sides of the housing 321 are provided with a first circular hole, a second circular hole, and a third circular hole that pass through each other. The first circular holes are spaced apart at the top of the second circular holes, and the third circular holes are spaced apart at the rear ends of the first and second circular holes.

[0030] The curling blade 23 includes an upper curling blade 231 and a lower curling blade 232, which form a curling channel. The upper curling blade 231 is spaced apart at the top of the lower curling blade 232, and the upper curling blade 231 and the lower curling blade 232 have the same width.

[0031] Specific implementation process: The filament bundle first enters from the rear side of the crimping box 2, passing through the crimping channel formed by the upper crimping blade 231 and the lower crimping blade 232. The front end of the crimping blade is precisely aligned with the inter-roller channel between the first crimping roller 21 and the second crimping roller 22, ensuring that the filament bundle is stably guided to the clamping area of ​​the first crimping roller 21 and the second crimping roller 22. After entering the inter-roller channel, the filament bundle is strongly clamped and pulled by the high-speed rotating first crimping roller 21 and the second crimping roller 22. The surface structure of the first crimping roller 21 and the second crimping roller 22 applies compression, friction, and bending to the filament bundle, forcing the filament bundle to produce crimping deformation. During this process, the cylinder 242 pushes the copper side plate 245 to tightly fit against the end faces of the first crimping roller 21 and the second crimping roller 22, forming a sealed chamber to prevent the filament bundle from laterally scattering. While sealing and pressurizing, the first servo motor 241 drives the gear set 243 to rotate through the first sprocket. The gear set 243 adopts a four-stage reduction design, and the first gear to the second gear... The four gears mesh with decreasing teeth, ultimately transmitting power to the copper side plate 245, which is coaxially fixed with the first gear, causing it to rotate slowly. During the winding process, the filament continuously rubs against the inner edge of the copper side plate 245. The rotation of the copper side plate 245 constantly renews its friction surface, significantly extending the effective service life of the copper side plate 245 and reducing downtime for replacement and waste filament generation caused by wear of the copper side plate 245. The power for the first winding roller 21 and the second winding roller 22 is provided by the transmission box 32. The second servo motor 31 drives the third input shaft 327 to rotate through the second coupling. The seventh gear sleeved on the third input shaft 327 drives the fifth and sixth gears meshing with it to rotate synchronously. The first output shaft 325 drives the first winding roller 21 through the first universal joint, and the second output shaft 326 drives the second winding roller 22 through the second universal joint, ensuring that the speed of the first winding roller 21 and the second winding roller 22 are strictly synchronized and the steering is precisely matched, achieving efficient and stable winding traction.
