A control system for the operation of a doubling machine yarn

Abstract

A yarn operation control system for a doubling machine belongs to the field of doubling machine technology. The left and right movement of the clutch drive chuck enables disengagement and engagement with the clutch fixed chuck. When the clutch drive chuck moves to the right, it disengages from the clutch fixed chuck, while the clutch main pulley continues to rotate due to the internal bearing assembly. The clutch main shaft stops rotating, allowing the external main shaft power to operate without stopping, thus achieving single-spindle single-control function for the doubling machine. The yarn is stabilized through the setting of the yarn guide ring without affecting the overall tension, achieving a stabilizing effect. A metal detector detects metal objects in real time. When a metal object is detected, a control cylinder disengages the clutch drive chuck from the clutch fixed chuck. The electromagnetic suction block attracts the gravity block, and the magnetic guide block also has magnetic force. When a metal object is detected, the rear side of the magnetic guide block can attract the metal object, facilitating cleaning.

Description

Technical Field

[0001] This invention belongs to the technical field of twisting machine equipment, specifically relating to a twisting machine yarn operation control system. Background Technology

[0002] In the field of textile production technology, the doubling machine, as a textile equipment that can twist and bond two or more single yarns into a ply yarn, has been widely used.

[0003] Twisting machines can be divided into two types: collective drive twisting machines and electronic single-spindle single-control twisting machines;

[0004] I. Collective drive twisting machine

[0005] 1. It has a simple structure, low price, strong versatility, and is widely used in the market;

[0006] 2. It lacks single-spindle single-control function and can only stop and start the entire machine.

[0007] II. Electronic Single-Spindle Single-Control Twisting Machine

[0008] 1. The mechanical transmission is controlled by multiple motors, and each transmission shaft has a single motor;

[0009] 2. Multi-motor control leads to increased costs;

[0010] 3. Multi-motor control places higher demands on electrical control systems, resulting in a higher failure rate during use;

[0011] 4. When the drive shaft is used for low-speed and high-speed transmission, different types of motors need to be used. Stepper motors are used for low-speed transmission, and servo motors are used for high-speed transmission.

[0012] 5. When a single-spindle, single-control twisting machine stops, the yarn is prone to jumping, which can cause the yarn spool to break.

Bearing mounting holes are provided in the middle of the left and right sides of the clutch frame. Both sides of the clutch frame are rotatably connected to the clutch main shaft through a first bearing, which is disposed in the bearing mounting hole.

[0017] The clutch mechanism includes a fixed clutch sprocket, a main clutch pulley, a drive clutch sprocket, and a shift push rod. The fixed clutch sprocket is mounted on the clutch main shaft, and an inner bearing assembly is provided on the middle section of the clutch main shaft. The main clutch pulley comprises a pulley portion and a connecting sleeve. The main clutch pulley is sleeved on the clutch main shaft in the direction of the fixed clutch sprocket, and the connecting sleeve is sleeved on the outside of the inner bearing assembly. Several racks are evenly distributed in a ring on the outer wall of the connecting sleeve. The drive clutch sprocket comprises a sprocket surface and a moving sleeve. The inner ring surface of the movable sleeve has a rack groove with the same number as the rack. The movable sleeve is fitted onto the connecting sleeve, and the rack slides in the rack groove. Both ends of the movable sleeve are provided with retaining rings. The actuating push rod is U-shaped. The movable sleeve is located inside the actuating push rod. The opening end of the actuating push rod is movably hinged to the upper and lower side walls inside the clutch frame. The rods on the upper and lower sides of the actuating push rod are located between the retaining rings. A cylinder is provided on the front side of the clutch frame. The end of the telescopic rod of the cylinder is hinged to the rear end of the actuating push rod.

[0018] Preferably, the lower support rod is detachably inserted laterally into the mounting base.

[0019] Preferably, the rear end of the movable seat is connected to an extension plate, and the rear end of the extension plate is provided with a metal detector.

[0020] Preferably, an electromagnetic suction block is provided in the middle of the expansion plate, a flat plate is provided at the upper end of the finger rod, a pull rod is vertically and movably installed through the middle of the flat plate, the upper end of the pull rod is connected to the lower end of the thread ring, and a bolt is connected to the lower end of the pull rod. The bolt is located between the thread ring and the flat plate and on the pull rod, and is also located between the bolt and the flat plate and on the pull rod. A gravity block is connected to the lower end of the bolt.

[0021] Preferably, a magnetic block is detachably connected to the rear side of the gravity block, and the magnetic block is located above the metal detector.

[0022] Preferably, the left and right walls on the rear side of the clutch frame are provided with through slots, which are connected to the bearing mounting holes.

[0023] Preferably, a bearing sleeve is provided on the outer side of each of the two first bearings, and the outer ring of the bearing sleeve is bolted to the clutch frame.

[0024] Preferably, a transmission toothed plate compression spring is provided between the inner side of the movable sleeve and the left end of the connecting sleeve.

[0025] Preferably, push rod bearings are provided on the middle sides of the upper and lower sides of the push rod that are close to each other.

[0026] Preferably, both ends of the clutch main shaft are symmetrically provided with transmission pulleys.

[0027] The beneficial effects of this invention are as follows:

[0028] The yarn thread enters from below into the rear guide ring, then into the guide ring, and then into the front guide ring, before exiting through the exit ring. The flexible design of the movable seat allows the yarn to move with the machine when tensioned. The guide ring is positioned lower than the two guide rings, providing downward tension. The cylinder is connected to the control air source on the twisting machine, controlling the cylinder to push the push rod, which in turn moves it laterally within the two retaining rings, causing the clutch drive sprocket to move laterally. The push rod bearing rests low against the inner side of the retaining rings, ensuring smooth rotation of the clutch drive sprocket and reducing friction with the retaining rings. The left and right movement of the drive chuck enables disengagement and engagement with the fixed clutch chuck. The pulley section is connected to the power shaft of the twisting machine via belt drive. When the drive chuck moves to the right, it disengages from the fixed clutch chuck, while the main clutch pulley continues to rotate due to the inner bearing assembly. The main clutch shaft stops rotating, allowing the external main shaft power to operate without stopping, thus enabling single-spindle single-control function of the twisting machine. When the drive chuck disengages from the fixed clutch chuck, the main clutch shaft stops rotating. At this time, the yarn becomes tangled and jumps due to the power stoppage, leading to yarn breakage. The yarn is stabilized by the guide ring without affecting the overall tension, thus achieving a stabilizing effect.

[0029] Because existing twisting machines generate static electricity during yarn twisting, this static electricity can easily attract small iron filings, causing the entire yarn spool to become unusable. By using a metal detector to detect metal objects in real time, when a metal object is detected, a control cylinder disengages the clutch drive plate from the clutch stationary plate, allowing for manual removal of the metal object. The electromagnetic suction block attracts the gravity block, and the magnetic guide block also has magnetic force; when a metal object is detected, its rear side can attract and hold the metal object, facilitating cleaning.

[0041] The following examples, in conjunction with the appendix, illustrate the concepts. Figures 1-10 The structure is shown below, and the technical solution of the present invention will be further described in detail.

[0042] Example 1: A yarn operation control system for a doubling twister includes a yarn stabilizing mechanism and a clutch body. The clutch body includes a clutch frame 1 and a clutch main shaft 2 rotatably disposed in the clutch frame 1. A clutch mechanism is provided on the inner side of the clutch frame 1.

[0043] The thread stabilizing mechanism includes a support base 401, a picking finger rod 402, and a fixed support rod 403. The support base 401 is detachably mounted on the top of the clutch frame 1. A movable seat 405 is rotatably mounted on the upper surface of the support base 401. A mounting seat 406 is mounted on the upper side of the movable seat 405. The fixed support rod 403 is located at the upper end of the mounting seat 406. An upper support rod 407 extends rearward from the upper end of the fixed support rod 403. A lower support rod 408 is inserted into the rear side of the mounting base 406. The picking finger rod 402 is inclinedly arranged on the rear end of the lower support rod 408. The upper end of the picking finger rod 402 is provided with a thread-passing ring 409. Thread-leading rings 410 are provided on both the left and right sides of the thread-passing ring 409. Both thread-leading rings 410 are connected to the fixed support rod 403. The thread-passing ring 409 is also located below the fixed support rod 403. A thread-exiting ring 411 is embedded in the middle of the upper support rod 407.

[0044] The clutch frame 1 has bearing mounting holes 101 in the middle of both the left and right sides. Both sides of the clutch frame 1 are rotatably connected to the clutch main shaft 2 through a first bearing 201, which is located in the bearing mounting hole 101.

[0045] The clutch mechanism includes a fixed clutch sprocket 301, a main clutch pulley 302, a drive clutch sprocket 303, and a push rod 304. The fixed clutch sprocket 301 is mounted on the clutch main shaft 2. An inner bearing assembly 202 is provided on the middle section of the clutch main shaft 2. The main clutch pulley 302 consists of a pulley portion 3021 and a connecting sleeve 3022. The main clutch pulley 302 is sleeved on the clutch main shaft 2 in the direction of the sprocket side of the fixed clutch sprocket 301, and the connecting sleeve 3022 is sleeved on the outside of the inner bearing assembly 202. A plurality of racks 3023 are evenly distributed in a ring on the outer wall of the connecting sleeve 3022. The drive clutch sprocket 303 consists of a sprocket surface 3031 and a moving sleeve 3032. The inner ring surface of the movable sleeve 3032 is provided with rack grooves 3033 in the same number as the rack 3023. The movable sleeve 3032 is sleeved on the connecting sleeve 3022, and the rack 3023 slides in the rack grooves 3033. Both ends of the movable sleeve 3032 are provided with retaining rings 3034. The actuating push rod 304 is U-shaped. The movable sleeve 3032 is located inside the actuating push rod 304. The opening end of the actuating push rod 304 is movably hinged to the upper and lower side walls inside the clutch frame 1. The rods on the upper and lower sides of the actuating push rod 304 are located between the retaining rings 3034. A cylinder 305 is provided on the front side of the clutch frame 1. The telescopic rod end of the cylinder 305 is hinged to the rear end of the actuating push rod 304.

[0046] The specific implementation method is as follows:

[0047] The yarn thread is inserted from below into the rear guide ring 410, then into the guide ring 409, then into the front guide ring 410, and finally out through the exit ring 411. The flexible setting of the movable seat 405 allows the yarn to move with the yarn when it is tensioned. The guide ring 409 is positioned lower than the two guide rings 410, so that the guide ring 409 can exert a certain pulling force downward on the yarn.

[0048] Cylinder 305 is connected to an external control air source. Cylinder 305 pushes push rod 304 to swing. Push rod 304 moves laterally within two retaining rings 3034, causing clutch drive sprocket 303 to move laterally. The left and right movement of clutch drive sprocket 303 enables disengagement and engagement with clutch fixed sprocket 301. Pulley 3021 is connected to external power shaft via belt drive. When clutch drive sprocket 303 moves to the right, it disengages from clutch fixed sprocket 301, while clutch main pulley 302 continues to rotate due to the inner bearing assembly 202. Clutch main shaft 2 stops rotating, so that the external main shaft power does not need to be stopped, realizing the single spindle single control function of the twisting machine.

[0049] When the clutch drive chuck 303 disengages from the clutch fixed chuck 301, the clutch main shaft 2 stops rotating. At this time, the yarn becomes tangled and jumps due to the stop of power, resulting in yarn breakage. The yarn is stabilized by the setting of the thread guide ring 409 without affecting the overall tension, thus achieving a stabilizing effect. Example

[0050] Based on Example 1, this embodiment further specifies that the lower support rod 408 is detachably inserted laterally into the mounting base 406, so as to realize the structure of the support rod 408 to be replaced later, and thus the finger rod 402 can be replaced as needed for production, thereby improving practicality.

[0051] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again. Example

[0052] This embodiment further defines, based on embodiment 1, that the rear end of the movable seat 405 is connected to an extension plate 404, and the rear end of the extension plate is equipped with a metal detector 412. Because existing twisting machines generate static electricity during yarn twisting, this static electricity can easily attract small iron filings, causing the entire yarn canister to become unusable. The metal detector 412 detects metal objects in real time. When a metal object is detected, the cylinder 305 is controlled to disengage the clutch drive disc 303 from the clutch fixed disc 301, allowing for manual removal of the metal object.

[0053] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again. Example

[0054] This embodiment further defines, based on embodiment 3, that an electromagnetic suction block 413 is provided in the middle of the expansion plate 404, a flat plate 414 is provided at the upper end of the finger rod 402, a pull rod 415 is vertically and movably provided in the middle of the flat plate 414, the upper end of the pull rod 415 is connected to the lower end of the thread ring 409, a bolt 416 is connected to the lower end of the pull rod 415, a support spring 417 is sleeved between the thread ring 409 and the flat plate 414 and on the pull rod 415, and between the bolt 416 and the flat plate 414 and on the pull rod 415, and a gravity block 418 is connected to the lower end of the bolt 416;

[0055] The electromagnetic suction block 413 magnetically attracts the gravity block 418, which in turn pulls the bolt 416 downward. The bolt 416 then pulls the pull rod 415, causing the wire ring 409 to move downward. The wire ring 409 pulls the wire downward, thus stabilizing the wire when the machine stops. When the machine starts, the electromagnetic suction block 413 is deactivated, and the wire ring 409 is reset by the support spring 417.

[0056] The other parts of this embodiment are the same as those in Embodiment 3 above, and will not be described again. Example

[0057] This embodiment further specifies, based on embodiment 4, that the rear side of the gravity block 418 is detachably connected to a magnetic block 419. The magnetic block 419 is located above the metal detector 412. The gravity block 418 is attracted by the magnetic force of the electromagnetic suction block 413. At the same time, the magnetic block 419 also has a magnetic force. When a metal object is detected, the rear side of the magnetic block 419 can attract the metal object, which is convenient for personnel to clean.

[0058] The other parts of this embodiment are the same as those in Embodiment 4 above, and will not be described again. Example

[0059] Based on embodiment 1, this embodiment further specifies that the left and right walls of the rear side of the clutch frame 1 are provided with through slots 102. The through slots 102 are connected to the bearing mounting holes 101. After the clutch mechanism is assembled in the middle of the clutch main shaft 2, the clutch main shaft 2 can be quickly installed into the inner side of the clutch frame 1 through the through slots 102.

[0060] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again. Example

[0061] Based on embodiment 6, this embodiment further specifies that a bearing sleeve 203 is provided on the outer side of each of the two first bearings 201. The outer ring of the bearing sleeve 203 is connected to the clutch frame 1 by bolts. The bearing sleeve 203 stabilizes the stability of the first bearing 201 and avoids the impact of the opening of the through slot 102 on the operation of the first bearing 201.

[0062] The other parts of this embodiment are the same as those in Embodiment 6 above, and will not be described again. Example

[0063] Based on embodiment 1, this embodiment further specifies that a transmission toothed plate compression spring 306 is provided between the inner side of the movable sleeve 3032 and the left end of the connecting sleeve 3022. When the cylinder 305 is reset, the transmission toothed plate compression spring 306 resets and engages the clutch transmission toothed plate 303 with the clutch fixed toothed plate 301, thereby playing an auxiliary role.

[0064] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again. Example

[0065] Based on Embodiment 1, this embodiment further specifies that push rod bearings 307 are provided on the middle of the upper and lower sides of the push rod 304, which are close to each other. The push rod 304 causes the clutch transmission disc 303 to move laterally within the two retaining rings 3034. The push rod bearings 307 are close to the inner side of the retaining rings 3034, so that the clutch transmission disc 303 can maintain smooth rotation, and the push rod bearings 307 reduce the frictional force in contact with the retaining rings 3034.

[0066] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again.

[0067] Example 10:

[0068] Based on embodiment 1, this embodiment further specifies that both ends of the clutch main shaft 2 are symmetrically provided with transmission pulleys 204. The symmetrically provided transmission pulleys 204 make the rotation of the clutch main shaft 2 more stable. One of the transmission pulleys 204 is connected to the overfeed shaft of the existing double twister by belt drive, and the other transmission pulley 204 is connected to the friction wheel shaft 5 of the existing double twister by belt drive.

[0069] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again.

[0070] Application principle of this invention:

[0071] When this invention is installed on a doubling twister, the yarn thread is inserted from below into the rear guide ring 410, then into the guide ring 409, and then into the front guide ring 410, before exiting through the exit ring 411. The flexible arrangement of the movable seat 405 allows the yarn to move with the yarn when tensioned. The guide ring 409 is positioned lower than the two guide rings 410, allowing it to exert a certain downward pulling force on the yarn. The cylinder 305 is connected to the control air source on the doubling twister, enabling control of the cylinder 305. The cylinder 305 pushes the actuating push rod 304 to swing, causing the clutch drive sprocket 303 to move laterally within the two retaining rings 3034. The push rod bearing 307 rests low against the inner side of the retaining rings 3034, ensuring smooth rotation of the clutch drive sprocket 303. 307 reduces the frictional force in contact with the retaining ring 3034. The left and right movement of the clutch drive sprocket 303 enables disengagement and engagement with the clutch fixed sprocket 301. The pulley 3021 is connected to the power shaft of the twisting machine via belt drive. When the clutch drive sprocket 303 moves to the right, it disengages from the clutch fixed sprocket 301, while the clutch main pulley 302 continues to rotate due to the inner bearing assembly 202. The clutch main shaft 2 stops rotating, so that the external main shaft power does not need to be stopped, and the single spindle single control function of the twisting machine can be realized. When the clutch drive sprocket 303 disengages from the clutch fixed sprocket 301, the clutch main shaft 2 stops rotating. At this time, the yarn jumps and becomes tangled due to the power stop, resulting in yarn breakage. The setting of the yarn guide ring 409 stabilizes the yarn without affecting the overall tension, thus achieving a stabilizing effect.

[0072] Because existing twisting machines generate static electricity during yarn twisting, this static electricity can easily attract small iron filings, causing the entire yarn spool to become unusable. The metal detector 412 detects metal objects in real time. When a metal object is detected, the control cylinder 305 disengages the clutch drive disc 303 from the clutch fixed disc 301, allowing for manual removal of the metal object. The electromagnetic suction block 413 magnetically attracts the gravity block 418, and the magnetically conductive block 419 also possesses magnetic force. When a metal object is detected, its rear side can attract and hold the object, facilitating cleaning.

[0073] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
