Description

Technical Field

[0001] This application relates to the technical field of stranding machines, and particularly relates to a rocker-type stranding machine. Background Art

[0002] A rocker-type stranding machine generally includes an inlet wire group, a frame, a twisting group, a wire arranging group, and a rocker group. The function of the inlet wire group is to measure the stranding length and disperse multiple strands of yarn into the stranding. The function of the frame is to fix and carry the twisting group, the wire arranging group, and the rocker group. Both the twisting group and the wire arranging group are placed inside the structure of the rocker group. The function of the twisting group is to change the stranding twist of the yarn. It includes a large sheave and a small sheave. The bone strip is wound around the large sheave and the small sheave multiple times and then sent to the wire arranging group. Among them, by adjusting the rotation speed of the large sheave, the conveying speed of the bone strip is changed, thereby adjusting the stranding twist of the yarn.

[0003] The function of the wire arranging group is to neatly arrange the twisted yarn on the yarn tube. Different rotation directions of the rocker group can change the twisting direction of the stranding. There is also a protective cover above the frame, which can safely protect the twisting group, the wire arranging group, and the rocker group.

[0004] Among them, the existing rocker-type stranding machine still has the following problems in actual use: First of all, since the wire arranger can only rotate forward for wire arranging and cannot rotate backward for wire arranging, when the motor rotates backward to switch the twisting direction, it is necessary to convert the wire arranger to rotate forward, otherwise it will not arrange wire. Therefore, a set of structures such as a commutation fixing plate, a small commutation gear, and a large commutation gear are usually set up to keep the wire arranger rotating forward all the time. That is, when the motor rotates in reverse, the screws on the commutation fixing plate need to be loosened, and the position of the commutation fixing plate is adjusted so that the transmission between the friction gear and the wire arranging intermediate gear changes from three gears to two gears. By reducing one gear engagement to change the transmission direction, the wire arranger still maintains forward rotation.

[0005] In actual use, although the above structure can achieve the function of commutation, since it is necessary to manually disassemble and reinstall the commutation fixing plate every time after commutation, it is too cumbersome.

[0006] Secondly, when the motor rotates backward to switch the twisting direction, the rotation direction of the twisting group will also change. That is to say, the yarn tube, the large sheave, and the small sheave will all change the rotation direction, which makes the winding method of the bone strip on the yarn tube, the large sheave, and the small sheave also change. Thus, on the one hand, the bone strip is pre-wound before the motor starts. If the winding direction is incorrect, it has to be re-wound. At the same time, if the commutation fixing plate is forgotten to be adjusted, it will also lead to abnormal operation. This increases the operation difficulty of workers, raises the operation requirements for workers, and is likely to affect the production efficiency. Summary of the Invention

[0007] To solve the above problems simultaneously, the present application provides a rocker type stranding machine.

[0008] The rocker type stranding machine provided by the present application adopts the following technical solutions: A rocker type stranding machine includes a frame, a twisting adjustment group and a wire arranging group arranged on the frame. The twisting adjustment group includes a large driving gear, a large sheave, a lower intermediate gear meshing with the large sheave, and a transmission mechanism for drivingly connecting the large driving gear and the lower intermediate gear. The transmission mechanism includes a first upper change gear and a second upper change gear coaxially arranged with the large driving gear, a first ratchet and pawl structure arranged between the first upper change gear and the rotating shaft of the large driving gear, a second ratchet and pawl structure arranged between the second upper change gear and the rotating shaft of the large driving gear, a first lower change gear and a second lower change gear coaxially connected with the lower intermediate gear. A first transmission wheel group with an odd number of gear teeth is arranged between the first lower change gear and the first upper change gear, and a second transmission wheel group with an even number of gear teeth is arranged between the second lower change gear and the second upper change gear; The driving directions of the first ratchet and pawl structure and the second ratchet and pawl structure are opposite, and the polished rod of the wire arranging group is drivingly connected with the friction gear of the twisting adjustment group.

[0009] By adopting the above technical solutions, through the setting of the first and second ratchet and pawl structures with opposite driving directions and the first and second transmission wheel groups with odd and even numbers of gear teeth respectively, when the large driving gear rotates forward and backward respectively, only one of the first and second ratchet and pawl structures can achieve transmission. For example, when rotating forward, the first ratchet and pawl structure transmits power, while the second ratchet and pawl structure does not transmit power. At this time, the first lower change gear is driven to rotate forward through the first transmission wheel group; when rotating backward, the first ratchet and pawl structure does not transmit power, while the second ratchet and pawl structure transmits power. At this time, the second lower change gear is driven to rotate forward through the second transmission wheel group. In this way, no matter whether the motor rotates forward or backward, the lower intermediate gear always rotates forward. Therefore, when switching the twisting direction, there is no need to adjust the winding method of the bone strip. And because the lower intermediate gear always rotates forward and the friction gear is driven to rotate by the large sheave, the polished rod of the wire arranging group can also always rotate forward after transmission.

[0010] In one embodiment: a transition adjustment wheel is arranged in both the first transmission wheel group and the second transmission wheel group. An adjustment arm for maintaining the meshing state of the transition adjustment wheel is rotatably installed on the frame, and the transition adjustment wheel is slidably installed on the adjustment arm.

[0011] By adopting the above technical solution, the adjustment arm can adjust the position of the transition adjustment wheel, so that when replacing and adjusting the transmission ratio of the first lower replacement gear and the second lower replacement gear, it is convenient to adjust the position of the transition adjustment wheel, so as to quickly re-engage with the replaced first lower replacement gear and the second lower replacement gear.

[0012] In one embodiment: a compression spring for providing a tendency force towards the end of the adjustment arm away from the rotating end to the transition adjustment wheel is provided on the adjustment arm.

[0013] By adopting the above technical solution, the setting of the compression spring can automatically adjust the position of the transition adjustment wheel. By cooperating with the rotatable adjustment arm, when the first lower replacement gear and the second lower replacement gear are installed, the adjustment of the transition adjustment wheel can be automatically completed.

[0014] In one embodiment: a limiting rod for restricting the sliding of the transition adjustment wheel is threadedly connected to the adjustment arm, and the limiting rod is disposed through the compression spring.

[0015] By adopting the above technical solution, the setting of the limiting rod can, when in the driving process, in the case that the compression spring cannot keep the transition adjustment wheel stable and transmission slipping occurs, adjust the limiting rod to press against the transition adjustment wheel, so that its flexible limit by the compression spring becomes a rigid limit.

[0016] In one embodiment: a shifting assembly slidable on the transition shaft is installed on the transition shaft of the lower transition gear. A plurality of shifting gears with different sizes are provided on the shifting assembly, and adjacent two shifting gears are connected by a guiding surface in a transitional manner; the shifting gear meshing with the first transmission wheel set is the first lower replacement gear, and the shifting gear meshing with the second transmission wheel set is the second lower replacement gear, and the diameters of the first lower replacement gear and the second lower replacement gear are different.

[0017] By adopting the above technical solution, through the setting of the shifting assembly, by adjusting the position of the shifting assembly, that is, axially moving the shifting assembly, and at the same time under the compensation and adjustment of the adjustment arm and the compression spring, the transmission ratio can be directly adjusted by switching different sizes without disassembling the first lower replacement gear and the second lower replacement gear. At the same time, the first lower replacement gear and the second lower replacement gear are designed with different sizes, so that the twist is different when the motor rotates forward and backward, that is, the twist can be directly changed by adjusting the forward and reverse rotation of the motor.

[0018] In one embodiment: the shifting assembly includes a plugging rod axially inserted into the transition shaft and a threaded rod rotatably connected to the transition shaft. The plugging rod is fixedly connected to the shifting gear, the threaded rod is threadedly connected to the plugging rod, and one end of the threaded rod extends out of the transition shaft or the shifting gear to form an operation part.

[0019] By adopting the above technical solution, the axial position adjustment of the shift assembly can be controlled by rotating the threaded rod through the operating part.

[0020] In one embodiment: the first ratchet pawl structure and the second ratchet pawl structure have the same structure, and the ratchet and pawl of the first ratchet pawl structure are provided with repelling magnets, and when the ratchet rotates in the opposite direction, the repulsive force of the magnet drives the pawl to rotate.

[0021] By adopting the above technical solution, since the first lower matching hanging wheel and the second lower matching hanging wheel keep rotating synchronously, although only one of the first ratchet pawl structure and the second ratchet pawl structure is transmitted, the first lower matching hanging wheel and the second lower matching hanging wheel will transmit in the opposite direction. For example, when the first ratchet pawl structure drives the first lower matching hanging wheel to rotate, the second lower matching hanging wheel will drive the second upper matching hanging wheel to rotate in the opposite direction of the first upper matching hanging wheel. In this way, the ratchet and pawl of the second ratchet pawl structure will rotate very quickly relative to each other, resulting in a loud impact sound, and easily causing damage to the ratchet pawl structure. By designing the magnets that repel each other, the contact force between the ratchet and the pawl during relative rotation can be reduced, and even the direct contact between the ratchet and the pawl can be avoided.

[0022] In one embodiment, the twist adjustment group further includes a toggle assembly for synchronously controlling the axial movement of the ratchet wheels of the first ratchet pawl structure and the second ratchet pawl structure by being controlled by the forward and reverse rotation of the large transmission gear, and the first ratchet pawl structure and the second ratchet pawl structure are in staggered transmission cooperation.

[0023] By adopting the above technical solution, the toggle assembly is controlled by the forward and reverse rotation direction of the large transmission gear, and then the toggle assembly is used to control which of the first ratchet and pawl structures and the second ratchet and pawl structures can realize transmission normally, that is, when the ratchet of the first ratchet and pawl structure can cooperate with the pawl to transmit, the ratchet and pawl of the second ratchet and pawl structure are staggered. In this way, when the second upper changing wheel is driven to rotate in the reverse direction, the ratchet and pawl of the second ratchet and pawl structure will not come into contact.

[0024] In one embodiment: the toggle assembly includes a sleeve that is rotationally connected to the ratchet wheels of the first ratchet pawl structure and the second ratchet pawl structure at the same time, a driving member that is controlled to move back and forth by the forward and reverse rotation of the large transmission gear, and a connecting member that connects the driving member and the sleeve, and the driving member and the connecting member are connected by a damping connection. When the sleeve controls the two ratchets to complete the switching, the driving member overcomes the damping between the connecting member and the connecting member and rotates synchronously with the large transmission gear.

[0025] By adopting the above technical solution, the two ratchets are driven to slide axially through the shaft sleeve without affecting the rotation of the ratchets themselves. When the large transmission gear rotates forward and reverse, the driving member will slide in opposite directions, thereby achieving reciprocating movement during the forward and reverse rotation. At the same time, by limiting the movement of the shaft sleeve or directly limiting the axial movement stroke of the driving member, the driving member can only make a small reciprocating movement. When the driving member moves to the maximum distance, the driving member no longer moves but rotates synchronously with the large transmission gear. At this time, the driving member and the connecting member overcome the damping and rotate relative to each other.

[0026] In one of the embodiments: the driving member is a lead screw nut threadedly connected to the rotating shaft of the large transmission gear, and the rotating shaft of the large transmission gear is provided with a threaded section that cooperates with the lead screw nut.

[0027] By adopting the above technical solution, the lead screw nut is used as a driving member, which can reduce the resistance between the lead screw nut and the threaded section on the large transmission gear, so that the damping between the driving member and the connecting member does not need to be too large.

DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] In the description of the present application, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0032] Embodiment 1: A rocker type stranding machine, such as Figure 1 As shown, it includes a frame 100, and a twisting group 200, a rocker 300 and a wire arrangement group 400 arranged on the frame 100. The two ends of the rocker 300 are connected to the frame 100 through a main shaft respectively. The two main shafts are driven to rotate synchronously by the motor on the frame 100, and the rotation of the two main shafts drives the rocker 300 to rotate forward and reverse.

[0033] like Figure 2As shown in the figure, the twisting group 200 includes a twisting frame 210, a small driving gear 260, a large driving gear 220, a large sheave 230, a small sheave 280, a lower intermediate gear 240, a transmission mechanism 250, and a friction gear 270. Both ends of the twisting frame 210 are rotatably connected to two main shafts, and the main shaft on the right side penetrates the twisting frame 210 and is connected to the small driving gear 260. A bobbin 290 is detachably mounted on the twisting frame 210.

[0034] The large driving gear 220, the lower intermediate gear 240, and the small sheave 280 are all rotatably mounted on the twisting frame 210. The large driving gear 220 meshes with the small driving gear 260. The transmission mechanism 250 is used to drive and connect the large driving gear 220 and the lower intermediate gear 240. The friction gear 270 and the large sheave 230 are coaxially connected to the large driving gear 220. The large sheave 230 meshes with the lower intermediate gear 240. The friction gear 270 is provided with a friction plate and a brake shoe. The large sheave 230 drives the friction gear 270 to rotate by pushing the brake shoe. The bobbin gear 291 on the bobbin 290 meshes with the friction gear 270.

[0035] During operation, the small driving gear 260 is driven to rotate by the main shaft to drive the large driving gear 220 to rotate. The large driving gear 220 drives the lower intermediate gear 240 to rotate, and then drives the large sheave 230 to rotate. The large sheave 230 pushes the brake shoe to drive the friction gear 270 to rotate. The friction gear 270 drives the bobbin 290 to rotate. Among them, through the friction plate design, relative rotation can be formed between the friction gear 270 and the brake shoe by slipping, so as to adjust the rotation speed of the friction gear 270 to dynamically adapt to the diameter change caused by winding yarn on the bobbin 290.

[0036] The wire arranging group 400 includes a wire arranger 410 and a smooth rod 420. The smooth rod 420 is drivingly connected to the friction gear 270 of the twisting group 200. The wire arranger 410 is driven to move reciprocally by the rotation of the smooth rod 420.

[0037] Referring to the appendix Figure 3 , in this embodiment, taking the friction gear 270 maintaining forward rotation as an example for illustration, a first driven gear 430 and a second driven gear 440 are provided between the smooth rod 420 and the friction gear 270. The first driven gear 430 meshes with the friction gear 270. The first driven gear 430 and the second driven gear 440 mesh with each other. A first sprocket 450 is mounted on a bushing 710 of the second driven gear 440. A second sprocket 460 is provided on the smooth rod 420. The first sprocket 450 and the second sprocket 460 are connected by a chain. Through this setting, the smooth rod 420 and the friction gear 270 rotate in the same direction. Among them, when the transmission mechanism 250 is set to keep the friction gear 270 rotating only in reverse, the number of driven gears between the smooth rod 420 and the friction gear 270 can be increased or decreased.

[0038] Such asFigure 4 and Figure 5 As shown in Figure 5 , the transmission mechanism 250 includes a first upper change gear 251 and a second upper change gear 252 coaxially arranged with the large transmission gear 220, a first ratchet and pawl structure 253 arranged between the rotating shafts of the first upper change gear 251 and the large transmission gear 220, a second ratchet and pawl structure 254 arranged between the rotating shafts of the second upper change gear 252 and the large transmission gear 220, a first lower change gear 255 and a second lower change gear 256 coaxially connected to the lower intermediate gear 240, a first transmission wheel set 257 with an odd number of gear teeth arranged between the first lower change gear 255 and the first upper change gear 251, and a second transmission wheel set 258 with an even number of gear teeth arranged between the second lower change gear 256 and the second upper change gear 252.

[0039] Combined with the attached Figure 6 , the structures of the first ratchet and pawl structure 253 and the second ratchet and pawl structure 254 are the same, but the transmission directions are opposite. In this embodiment, the first ratchet and pawl structure 253 is taken as an example for description. The first ratchet and pawl structure 253 includes a ratchet 2531 and a pawl 2532. The ratchet 2531 is fixedly connected to the rotating shaft of the large transmission gear 220, and the ratchet 2531 is driven to rotate synchronously by the large transmission gear 220.

[0040] The pawl 2532 is rotatably installed on the first upper change gear 251. By the rotation of the ratchet 2531, the first upper change gear 251 can be driven to rotate unidirectionally. Through the settings of the first ratchet and pawl structure 253 and the second ratchet and pawl structure 254, when the large transmission gear 220 rotates forward and backward, only one of the first lower change gear 255 and the second lower change gear 256 can be driven to rotate.

[0041] Wherein, in order to reduce the impact during reverse rotation, repulsive magnets 2533 are provided on the ratchet 2531 and the pawl 2532 of the first ratchet and pawl structure 253 and the second ratchet and pawl structure 254, so that when the ratchet 2531 rotates in the reverse direction, the pawl 2532 is pushed to rotate by the repulsive force of the magnet 2533.

[0042] A transition adjustment wheel 2581 is provided in both the first transmission wheel set 257 and the second transmission wheel set 258. Among them, in order to simplify the structure, in this embodiment, the first transmission wheel set 257 only includes one transition adjustment wheel 2581 to form a single-gear transmission. In addition to one transition adjustment wheel 2581, the second transmission wheel set 258 also includes a second transmission gear 2582 to form a double-gear transmission.

[0043] In this way, by setting the transmission direction of the first ratchet pawl structure 253 and the second ratchet pawl structure 254, under the transmission of the first transmission wheel group 257 and the second transmission wheel group 258, it can be achieved that the large groove wheel 230 keeps rotating forward regardless of whether the motor rotates forward or reverse.

[0044] See attached Figure 4 The frame 100 is rotatably mounted with an adjusting arm 500 for maintaining the meshing state of the transition adjusting wheel 2581, and the transition adjusting wheel 2581 is slidably mounted on the adjusting arm 500. One end of the adjusting arm 500 is rotatably mounted on the twist adjusting frame 210, so that the adjusting arm 500 can swing freely on the twist adjusting frame 210, and the adjusting arm 500 is provided with a compression spring 510 for providing a tendency force to move away from the rotating end of the adjusting arm 500 to the transition adjusting wheel 2581, and the elastic force of the compression spring 510 can maintain the meshing state between the transition adjusting wheel 2581 and the first lower matching hanging wheel 255 and the first upper matching hanging wheel 251, or the second lower matching hanging wheel 256 and the second transmission gear 2582.

[0045] Combined with Figure 7 The regulating arm 500 is threadedly connected with a limit rod 520 for limiting the slippage of the transition regulating wheel 2581, and the limit rod 520 is inserted into the compression spring 510. The setting of the limit rod 520, during the driving process, when the compression spring 510 cannot keep the transition regulating wheel 2581 stable and the transmission slips, the limit rod 520 can be adjusted to press against the transition regulating wheel 2581 to change the flexible limit of the compression spring 510 into a rigid limit.

[0046] See attached Figure 5 A shift assembly 600 that can slide on the transition shaft 241 is installed on the transition shaft 241 of the lower transition gear 240. A plurality of shift gears 610 of different sizes are fixedly arranged on the shift assembly 600. The plurality of shift gears 610 are arranged in a gradually increasing or decreasing manner in the radial direction. Among them, the shift gear 610 meshing with the first transmission wheel set 257 is the first lower matching shifting wheel 255, and the shift gear 610 meshing with the second transmission wheel set 258 is the second lower matching shifting wheel 256, so that the diameters of the first lower matching shifting wheel 255 and the second lower matching shifting wheel 256 are different.

[0047] In this embodiment, four shift gears 610 are used as an example, and two adjacent shift gears 610 are transitionally connected by a guide surface 611. The guide surface 611 is provided for guidance, so that the shift assembly 600 can conveniently switch between the shift gears 610 when moving in the circumferential direction.

[0048] For details, please refer to the attached Figure 8The shift assembly 600 includes a plug-in rod 620 axially plugged into the transition shaft 241, and a threaded rod 630 rotatably connected to the transition shaft 241. The plug-in rod 620 is fixedly connected to the shift gear 610. The cross-section of the plug-in rod 620 adopts a polygonal structure, so that after the plug-in rod 620 is inserted into the transition shaft 241, the plug-in rod 620 and the transition shaft 241 rotate synchronously.

[0049] The threaded rod 630 is threadedly connected to the plug-in rod 620. One end of the threaded rod 630 extends out of the transition shaft 241 or the shift gear 610 to form an operating part 631. The operating part 631 can be a tool slot or a tool head with a hexagonal shape. In this embodiment, the operating part 631 takes a tool slot as an example.

[0050] By setting the shift assembly 600, adjusting the position of the shift assembly 600, i.e., axially moving the shift assembly 600, and under the compensation and adjustment of the adjustment arm 500 and the compression spring 510, the transmission ratio can be adjusted by directly switching different sizes without disassembling the first lower matching and changing hanging wheel 255 and the second lower matching and changing hanging wheel 256. At the same time, the first lower matching and changing hanging wheel 255 and the second lower matching and changing hanging wheel 256 are designed with different sizes, so that the twist is different when the motor rotates forward and reverse, that is, the twist can be changed directly by adjusting the forward and reverse rotation of the motor.

[0051] Embodiment 2: The difference from embodiment 1 is that Figure 9 and Figure 10 As shown, the twist adjustment group 200 also includes a toggle assembly 700 for synchronously controlling the axial movement of the ratchet 2531 of the first ratchet pawl structure 253 and the second ratchet pawl structure 254 by being controlled by the forward and reverse rotation of the large transmission gear 220. The toggle assembly 700 enables the first ratchet pawl structure 253 and the second ratchet pawl structure 254 to be staggered in transmission, that is, when the ratchet 2531 and the pawl 2532 of the first ratchet pawl structure 253 can cooperate in transmission, the ratchet 2531 and the pawl 2532 of the second ratchet pawl structure 254 are staggered with each other, and at this time, the rotation of the ratchet 2531 and the pawl 2532 of the second ratchet pawl structure 254 will not affect each other.

[0052] Combined with Figure 11, the toggling assembly 700 includes a bushing 710 rotatably connected to the ratchets 2531 of both the first ratchet and pawl structure 253 and the second ratchet and pawl structure 254 simultaneously, a driving member 720 reciprocally moved under the control of the forward and reverse rotations of the large transmission gear 220, and a connecting member 730 connecting the driving member 720 and the bushing 710. The driving member 720 is damping-connected to the connecting member 730. One end of the connecting member 730 away from the driving member 720 is connected to the bushing 710 through a connecting rod 740. Among them, the connecting member 730 and the bushing 710 are respectively located inside and outside the twisting frame 210, and the connecting rod 740 penetrates through the twisting frame 210. In this way, axial positioning is achieved, so that the bushing 710, the connecting member 730, and the connecting rod 740 can only axially slide along the rotating shaft of the large transmission gear 220.

[0053] Among them, the driving member 720 is a lead screw nut threadedly connected to the rotating shaft of the large transmission gear 220, and a threaded section cooperating with the lead screw nut is provided on the rotating shaft of the large transmission gear 220. And when the bushing 710 controls the two ratchets 2531 to complete the switching, the driving member 720 overcomes the damping with the connecting member 730 and rotates synchronously with the large transmission gear 220.

[0054] Refer to the appendix Figure 12 , a damping piece 731 and a damping spring 732 are provided between the driving member 720 and the connecting member 730. The damping piece 731 abuts against the outer wall of the driving member 720 through the damping spring 732, and the damping connection is achieved through the setting of the damping piece 731 and the damping spring 732.

[0055] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form.
