Description

Technical Field

[0001] This application belongs to the field of knitting technology, and in particular relates to a thread-cutting device for sock machines with a uniform thread-cutting function. Background Technology

[0002] During the knitting process of socks, such as when using jacquard weaving, a lot of excess yarn is generated. This excess yarn needs to be cut and removed promptly, otherwise it will affect the knitting process. On these circular knitting machines, the scissor mechanism is usually equipped with a suction device. When a yarn needs to be cut, the suction device creates negative pressure, pushing the yarn into the yarn clamping device, where the scissor mechanism cuts the yarn. The cut yarn is then discharged through the outlet on the suction device.

[0003] An existing invention patent with publication number CN113026186A discloses a thread-cutting device, including a split body, which is sequentially connected to a scissor disc and a split disc. A scissor device, a suction device, and a thread clamp device are mounted on the base of the split body. The split disc, scissor disc, and split body are sequentially connected to the head of a sock knitting machine by fasteners. A boss is provided on the split body, and a first groove is provided on the scissor disc, with the boss installed within the first groove. A blade portion is also provided on the outer edge of the scissor disc, and a first receiving groove is provided on the split disc, with the blade portion installed within the first receiving groove. The suction device includes a suction head and a suction pipe at one end of the suction head, which is tapered.

[0004] While the aforementioned thread-cutting device facilitates hooking and cutting the thread, in reality, the splitter is equipped with a hook. By hooking or releasing the loop at the toe of the sock, lint will fall from the yarn when the hook rubs against it or when the yarn is cut by the scissors. Some of this lint will become entangled on the hook. When the amount of entangled lint increases, it can cause the hook to jam when it extends or retracts, and in severe cases, it can even damage the hook. Workers need to clean the entangled lint, which increases the labor intensity of the workers and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing a thread-cutting device for sock machines with a uniform thread-cutting function, which can automatically clean up the fuzz tangled on the hook needle.

[0006] This application provides a thread-cutting device for a sock machine with a uniform thread-cutting function, comprising:

[0007] The frame includes the drive shaft and the driven shaft;

[0008] The head unit is mounted on the frame.

[0009] A thread cutting mechanism for cutting yarn, the thread cutting mechanism including a splitter, a hook, a scissor disc, and scissor blocks;

[0010] A suction device for sucking up cut yarn and installing it on the machine head, the suction device including a suction hood;

[0011] The transmission mechanism is mounted on the frame and connected between the drive shaft and the driven shaft;

[0012] The cleaning mechanism, used to remove lint from the hook needle, is located on the machine head and inside the suction hood;

[0013] The half disk is mounted on the driven shaft.

[0014] The drive shaft and driven shaft are mounted on the frame via bearings. The drive shaft is driven by a power unit, and the power of the drive shaft is transmitted to the driven shaft through a transmission mechanism. The rotation of the driven shaft drives the half disc and the scissor disc to rotate. The hook is mounted on the half disc. The hook hooks or releases the loop at the toe of the sock. The scissor disc and scissor blocks work together to cut the yarn. The suction device is connected to a negative pressure device. The cut yarn is discharged through the suction hood on the suction device. When the yarn cutting mechanism is in use, lint, broken fibers and other impurities fall off the yarn and get tangled on the hook. Once tangled, they cannot be sucked up by the suction device. As the impurities tangled on the hook increase, it becomes difficult for the hook to move. The cleaning mechanism automatically cleans the impurities tangled on the hook, ensuring the stable operation of the hook and reducing the labor intensity of manual cleaning. After the impurities are separated from the tangled state by the cleaning mechanism, they are quickly sucked up by the suction device.

[0015] Furthermore, the cleaning mechanism includes:

[0016] Mounting base, placed on the machine head;

[0017] Clean the window, placing it on the machine head and adjacent to the mounting base;

[0018] Switch structure, adapted to the cleaning window;

[0019] Cleaning roller;

[0020] The movable base is placed on the mounting base;

[0021] The drive cylinder is placed on the mounting base;

[0022] A drive unit, placed on a movable seat, drives the cleaning roller;

[0023] The drive cylinder drives the switch structure to open and the movable seat to move. The cleaning roller is installed on the movable seat. The half disc is provided with a first receiving groove and a second receiving groove. The cleaning window corresponds to the second receiving groove.

[0024] The mounting base and the machine head are connected by bolts or as a single unit. The hook is installed in the first receiving groove and is adapted to the second receiving groove. All the impurities wrapped around the hook are placed in the second receiving groove. The cleaning window is opened by the drive cylinder drive switch structure, and then the movable seat moves to move the cleaning roller into the second receiving groove. The cleaning roller is driven to rotate by the drive device to clean the impurities. The impurities separated by the cleaning roller are drawn away by the suction hood through the cleaning window.

[0025] When the hook is in normal use, the cleaning roller is placed in the cleaning window and the switch structure is in the closed state.

[0026] Furthermore, the switch structure includes;

[0027] A switch holder includes a base body and a switch plate, wherein two base bodies are provided;

[0028] Linkage rods are connected to the base body, and corresponding links are connected to each other;

[0029] The first push rod is connected to one of the pairs of connecting rods;

[0030] The connector rod is inserted into the first push rod;

[0031] The switch piece is placed on the upper and lower sides of the cleaning window, the connecting rods are evenly distributed around an axis, the first push rod is provided with a plug groove that matches the plug rod, and the first push rod is driven by a drive cylinder.

[0032] There are two switch bases, each with a connecting rod mounted on it. The connecting rods on the two bases are hinged together. The connecting rods mounted on the same base are evenly distributed around an axis and move radially. Each base has two or more connecting rods. The first push rod is hinged to the connecting rods. When the first push rod acts on the pair of connecting rods above, it controls the rotation of all the connecting rods, allowing the bases to move away from or closer to each other. The insertion rod abuts against the insertion slot, limiting the downward movement of the first push rod. When the first push rod is at its lowest position, the switch base is in the open state, and the switch plates are placed on the upper and lower sides of the cleaning window and are adapted to the machine head. When the switch base is in the closed state, the switch plates on both sides of the base abut against each other, and the cleaning roller is placed between the switch plates.

[0033] Furthermore, the movable seat includes:

[0034] movable cavity;

[0035] The first spring is placed in the movable cavity;

[0036] The second push rod is installed and connected to the drive cylinder block;

[0037] The second spring is placed between the movable seat and the mounting seat;

[0038] In this configuration, one end of the first push rod is placed in the movable cavity, one end of the second push rod is placed in the movable cavity, the first spring is placed between the first push rod and the second push rod, and the second push rod is provided with an abutment portion that is adapted to the movable seat.

[0039] The movable cavity facilitates the movement of the movable seat. The first spring is placed between the second push rod and the first push rod. When the drive cylinder acts on the second push rod, the second push rod moves. The first spring acts on the first push rod, enabling the first push rod to act on the connecting rod. The second spring acts on the movable seat, ensuring that when the drive cylinder pushes the second push rod to move, the switch seat opens first. After opening, the second push rod continues to move and abuts against the movable seat, thus moving the movable seat. The second spring prevents a rigid collision between the second push rod and the first push rod as the second push rod continues to move. When the second push rod resets under the drive of the drive cylinder, the second spring resets the movable seat first. Then, the movable seat pulls the first push rod, causing the switch seat to close.

[0040] Furthermore, the cleaning roller includes:

[0041] Roller body;

[0042] Clean the shaft;

[0043] The telescopic component is provided with a movable ring, which is movably connected to the cleaning shaft.

[0044] A cleaning hook is installed on a telescopic component, and the cleaning hook is elastic.

[0045] The first tooth is placed on the roller body;

[0046] The mounting ring is placed on the movable seat;

[0047] The first gear is adapted to the first tooth section;

[0048] The first rotating shaft is mounted on the movable base;

[0049] Ball bearings are mounted on a mounting ring and are adapted to the roller body;

[0050] The roller body is provided with a shrinkage groove that is adapted to the telescopic component. The roller body is provided with a cleaning groove that is adapted to the cleaning hook. The cleaning shaft is connected to the mounting ring. The first gear is mounted on the first rotating shaft. The first rotating shaft and the driving device are driven by the gear and the rotating shaft. The axis of the roller body and the axis of the cleaning shaft are parallel to each other.

[0051] The drive motor transmits power to the first rotating shaft. The first gear is mounted on the first rotating shaft and meshes with the first tooth, thereby driving the roller to rotate. The cleaning shaft is connected to the mounting ring. The axis of the roller is parallel to the axis of the cleaning shaft, with the axis of the cleaning shaft closer to the hook. The telescopic component is movably connected to the cleaning shaft through a movable ring, allowing the telescopic component to rotate around the axis of the cleaning shaft. The telescopic component is adapted to the shrinkage groove on the roller. When the roller rotates, it drives the telescopic component to rotate. Through the combined action of the cleaning shaft and the roller on the telescopic component, the telescopic component can extend and retract in the shrinkage groove, thus enabling the cleaning hook to extend and retract in the cleaning groove. When the cleaning hook moves towards the hook, it extends out of the cleaning groove, separating the impurities from the entangled state. When the cleaning hook moves away from the hook, it retracts into the cleaning groove, separating the impurities from the cleaning hook. The separated impurities are drawn off the roller by the suction device, preventing impurities from entangled on the roller. The ball bearings make the roller rotation more stable. Both sides of the hook are cleaned by the cleaning roller simultaneously, improving cleaning efficiency.

[0052] Furthermore, the roller body is inclined from top to bottom from the outer end toward the mounting ring, and the axes of the roller bodies on both sides of the mounting ring form an angle of 150-180°.

[0053] Impurities on the hook are entangled with each other. When the rollers on both sides of the mounting ring are at an angle, the cleaning roller provides a lateral force that moves the impurities towards the roller body when separating them. This causes impurities that are far from the roller body's range of action to move towards the roller body, reducing the number of lateral movement steps of the cleaning roller and still achieving complete removal of impurities from the hook, thus improving the cleaning effect of the cleaning roller. When the angle is less than 150°, the rollers on both sides of the mounting ring require a larger mounting ring, which is not conducive to the cleaning roller extending into the second receiving groove.

[0054] Furthermore, the transmission mechanism includes: a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear, a fifth transmission gear, a sixth transmission gear, and a clutch assembly;

[0055] The first and second transmission teeth are movably mounted on the drive shaft, and the third and fourth transmission teeth are coaxially connected. The first and third transmission teeth mesh with each other, the second and fourth transmission teeth mesh with each other, the third and fifth transmission teeth mesh with each other, and the fifth and sixth transmission teeth mesh with each other. The drive shaft is controlled by a clutch assembly to drive the first or second transmission teeth to rotate.

[0056] The clutch assembly controls the drive shaft to drive the first or second transmission gear to rotate. The transmission ratio between the first and third transmission gears is different from the transmission ratio between the second and fourth transmission gears, thereby achieving the adaptation of the rotation speed of the crochet hook to the knitting speed of the sock.

[0057] Furthermore, the clutch assembly includes:

[0058] Clutch seat, mounted on the frame;

[0059] The drive seat is hinged to the clutch seat;

[0060] The clutch element is located on the drive shaft;

[0061] The roller is mounted on the drive unit and abuts against the clutch.

[0062] The clutch has a first ratchet at one end and a second ratchet at the second transmission gear. The first ratchet and the second ratchet are adapted to each other. The clutch has a first limiting part at the other end. The first transmission gear has a first limiting groove adapted to the first limiting part. The clutch has a second limiting part on its inner wall surface and a second limiting groove adapted to the second limiting part on its drive shaft.

[0063] Under normal conditions, the drive seat acts on the clutch, causing the first limiting groove to mate with the first limiting part. The drive shaft drives the first transmission gear to rotate. A pneumatic or electric drive device acts on the drive seat, causing the drive seat to rotate and act on the clutch, thus moving the clutch. This causes the first ratchet to engage with the second ratchet, and the drive shaft drives the second transmission gear to rotate. The second limiting part mates with the second limiting groove to ensure that the clutch and the drive shaft rotate simultaneously.

[0064] The beneficial effects of this application are:

[0065] 1. The cleaning mechanism automatically cleans the impurities entangled on the hook, ensuring the stable operation of the hook and reducing the labor intensity of manual cleaning. After the impurities are separated from the entangled state by the cleaning mechanism, they are quickly sucked up by the suction device.

[0066] 2. The cleaning window is opened by first driving the switch structure through the drive cylinder, and then the movable seat moves to move the cleaning roller into the second receiving tank. The cleaning roller is then driven to rotate by the drive device to clean the impurities.

[0067] 3. When the drive cylinder acts on the second push rod, the second push rod moves. The first spring acts on the first push rod, enabling the first push rod to act on the connecting rod. The second spring acts on the movable seat, so that when the drive cylinder pushes the second push rod to move, the switch seat opens first. After opening, the second push rod continues to move and abuts against the movable seat, thereby moving the movable seat. The second spring ensures that the second push rod will not have a rigid collision with the first push rod when it continues to move.

[0068] 4. When the roller rotates, it drives the telescopic component to rotate. Through the combined action of the cleaning shaft and the roller on the telescopic component, the telescopic component can move in and out of the shrinkage groove, thereby enabling the cleaning hook to extend and retract in the cleaning groove. When the cleaning hook moves toward the hook needle, it extends out of the cleaning groove and separates the impurities from the entangled state. When the cleaning hook moves away from the hook needle, it retracts into the cleaning groove, separating the impurities from the cleaning hook. Attached Figure Description

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0080] The portable server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0081] Example 1:

[0082] like Figure 1 , Figure 2 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function, comprising:

[0083] The frame 100 includes a drive shaft 110 and a driven shaft 120;

[0084] The head unit 130 is mounted on the frame 100;

[0085] The thread cutting mechanism 200 is used to cut the yarn. The thread cutting mechanism 200 includes a splitter 210, a hook 220, a scissor disc 230, and a scissor block 240.

[0086] A suction device for sucking up cut yarn is installed on the machine head 130, and the suction device includes a suction hood 300;

[0087] The transmission mechanism 400 is placed on the frame 100 and connected between the drive shaft 110 and the driven shaft 120;

[0088] The cleaning mechanism 500 is used to clean the lint wrapped around the hook 220. It is placed on the machine head 130 and inside the suction hood 300.

[0089] The half disk 210 is mounted on the driven shaft 120.

[0090] The drive shaft 110 and driven shaft 120 are mounted on the frame 100 via bearings. The drive shaft 110 is driven by a power unit, and the power of the drive shaft 110 is transmitted to the driven shaft 120 through the transmission mechanism 400. The rotation of the driven shaft 120 drives the half disc 210 and the scissor disc 230 to rotate. The hook 220 is mounted on the half disc 210. The hook 220 hooks or releases the loops of the sock toe. The scissor disc 230 and the scissor block 240 work together to cut the yarn. The suction device is connected to a negative pressure device. The cut yarn is then drawn through the suction... When the suction hood 300 on the air device discharges air, the yarn cutting mechanism 200 will cause impurities such as lint and broken fibers to fall off and become entangled on the hook 220. Once entangled, they cannot be sucked up by the suction device. As the amount of impurities entangled on the hook 220 increases, it becomes difficult for the hook 220 to move. The cleaning mechanism 500 automatically cleans the impurities entangled on the hook 220, ensuring the stable operation of the hook 220 and reducing the labor intensity of manual cleaning. After the impurities are separated from the entangled state by the cleaning mechanism 500, they are quickly sucked up by the suction device.

[0091] Example 2:

[0092] like Figure 2 , Figure 3As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the cleaning mechanism 500 further includes:

[0093] Mounting base 510 is placed on machine head 130;

[0094] Cleaning window 520 is placed on machine head 130 and adjacent to mounting base 510;

[0095] Switch structure 530 is compatible with cleaning window 520;

[0096] Cleaning roller 570;

[0097] The movable base 540 is placed on the mounting base 510;

[0098] The drive cylinder 550 is mounted on the mounting base 510;

[0099] A drive device 560 is placed on a movable seat 540, and the drive device 560 drives the cleaning roller 570.

[0100] The drive cylinder 550 drives the switch structure 530 to open and the movable seat 540 to move. The cleaning roller 570 is installed on the movable seat 540. The half disc 210 is provided with a first receiving groove 211 and a second receiving groove 212. The cleaning window 520 corresponds to the second receiving groove 212.

[0101] The mounting base 510 and the machine head 130 are connected by bolts or integrally. The hook 220 is installed in the first receiving groove 211 and is adapted to the second receiving groove 212. The impurities wrapped on the hook 220 are placed in the second receiving groove 212. The cleaning window 520 is opened by driving the switch structure 530 through the drive cylinder 550. Then, the movable seat 540 moves to move the cleaning roller 570 into the second receiving groove 212. The cleaning roller 570 is driven to rotate by the drive device 560 to clean the impurities. The impurities separated by the cleaning roller 570 are drawn away by the suction hood 300 through the cleaning window 520.

[0102] When the hook 220 is in normal use, the cleaning roller 570 is placed in the cleaning window 520 and the switch structure 530 is in the closed state.

[0103] Example 3:

[0104] like Figure 3 , Figure 4 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to including the above-mentioned technical features, the switch structure 530 further includes:

[0105] A switch holder includes a base body 531 and a switch piece 532, wherein two base bodies 531 are provided;

[0106] Link 533 is connected to base 531, and the links 533 are connected to each other accordingly;

[0107] The first push rod 534 is connected to one of the pairs of connecting rods 533;

[0108] The connector 535 is inserted into the first push rod 534;

[0109] The switch piece 532 is placed on the upper and lower sides of the cleaning window 520, the connecting rod 533 is evenly distributed around an axis, the first push rod 534 is provided with a plug groove 536 adapted to the plug rod 535, and the first push rod 534 is driven by the drive cylinder 550.

[0110] There are two switch bases, each with a connecting rod 533 mounted on its base 531. The connecting rods 533 on both bases 531 are hinged together. The connecting rods 533 mounted on the same base 531 are evenly distributed around an axis and move radially. Each base 531 has two or more connecting rods 533. A first push rod 534 is hinged to both the connecting rods 533. When the first push rod 534 acts on the upper pair of connecting rods 533, it controls the rotation of all the connecting rods 533. The current seat bodies 531 move away from each other or closer to each other, and the insertion rod 535 abuts against the insertion slot 536, which restricts the downward movement of the first push rod 534. When the first push rod 534 is at the lowest position, the switch seat is in the open state, and the switch piece 532 is placed on the upper and lower sides of the cleaning window 520. The switch piece 532 is adapted to the machine head 130. When the switch seat is in the closed state, the switch pieces 532 on both sides of the seat body 531 abut against each other. At this time, the cleaning roller 570 is placed between the switch pieces 532.

[0111] Example 4:

[0112] like Figure 3 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the movable seat 540 further includes:

[0113] Movable cavity 541;

[0114] The first spring 542 is placed in the movable cavity 541;

[0115] The second push rod 543 is installed and connected to the drive cylinder 550;

[0116] The second spring 544 is positioned between the movable seat 540 and the mounting seat 510;

[0117] Wherein, one end of the first push rod 534 is placed in the movable cavity 541, one end of the second push rod 543 is placed in the movable cavity 541, the first spring 542 is placed between the first push rod 534 and the second push rod 543, and the second push rod 543 is provided with an abutment part 545, which is adapted to the movable seat 540.

[0118] The movable cavity 541 facilitates the movement of the movable seat 540. The first spring 542 is placed between the second push rod 543 and the first push rod 534. When the drive cylinder 550 acts on the second push rod 543, the second push rod 543 moves. The first spring 542 acts on the first push rod 534, enabling the first push rod 534 to act on the connecting rod 533. The second spring 544 acts on the movable seat 540, enabling the switch seat to open first when the drive cylinder 550 pushes the second push rod 543 to move. After opening, the second push rod 543 continues to move and abuts against the movable seat 540, thereby moving the movable seat 540. The second spring 544 prevents the second push rod 543 from rigidly colliding with the first push rod 534 as it continues to move. When the second push rod 543 resets under the drive of the drive cylinder 550, the second spring 544 causes the movable seat 540 to reset first. Then, the movable seat 540 pulls the first push rod 534 to close the switch seat.

[0119] When the hook 220 rotates to the position corresponding to the cleaning window 520, the movable seat 540 moves to make the cleaning roller 570 act on the impurities. After the cleaning process is completed, the movable seat 540 moves to reset the cleaning roller 570. Then the half plate 210 is rotated to make the next hook 220 that needs to be cleaned correspond to the cleaning window 520, and the cleaning roller 570 continues to clean the hook 220.

[0120] Example 5:

[0121] like Figure 3 , Figure 5 , Figure 6 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the cleaning roller 570 further includes:

[0122] Roller body 571;

[0123] Clean shaft 572;

[0124] The telescopic component 573 is provided with a movable ring 574, which is movably connected to the cleaning shaft 572.

[0125] A cleaning hook 575 is installed on a telescopic component 573, and the cleaning hook 575 is elastic.

[0126] The first tooth 576 is placed on the roller body 571;

[0127] Mounting ring 580 is placed on movable seat 540;

[0128] The first gear 581 is adapted to the first tooth 576;

[0129] The first rotating shaft 582 is mounted on the movable seat 540;

[0130] Ball bearing 583 is mounted on mounting ring 580 and is adapted to roller body 571;

[0131] The roller body 571 is provided with a shrinkage groove 577, which is adapted to the telescopic member 573. The roller body 571 is provided with a cleaning groove 578 adapted to the cleaning hook 575. The cleaning shaft 572 is connected to the mounting ring 580. The first gear 581 is mounted on the first rotating shaft 582. The first rotating shaft 582 and the driving device 560 are driven by gears and rotating shafts. The axis of the roller body 571 is parallel to the axis of the cleaning shaft 572.

[0132] The drive motor transmits power to the first rotating shaft 582. A first gear 581 is mounted on the first rotating shaft 582 and meshes with the first tooth 576, thereby driving the roller body 571 to rotate. The cleaning shaft 572 is connected to the mounting ring 580. The axis of the roller body 571 is parallel to the axis of the cleaning shaft 572, with the axis of the cleaning shaft 572 closer to the hook 220. The telescopic member 573 is movably connected to the cleaning shaft 572 via a movable ring 574, allowing the telescopic member 573 to rotate around the axis of the cleaning shaft 572. The telescopic member 573 is adapted to the shrinkage groove 577 on the roller body 571. When the roller body 571 rotates, it drives the telescopic member 573 to rotate, which in turn drives the roller body 571 to rotate via the cleaning shaft 572. The combined action of the telescopic components 573 allows them to extend and retract within the shrinkage groove 577, enabling the cleaning hook 575 to extend and retract within the cleaning groove 578. When the cleaning hook 575 moves toward the hook needle 220, it extends out of the cleaning groove 578, separating impurities from their entangled state. When the cleaning hook 575 moves away from the hook needle 220, it retracts into the cleaning groove 578, separating the impurities from the cleaning hook 575. The separated impurities are then drawn off the roller body 571 by the suction device, preventing impurities from entangled on the roller body 571. The ball bearings 583 further stabilize the rotation of the roller body 571. Both sides of the hook needle 220 are simultaneously cleaned by the cleaning roller 570, improving cleaning efficiency.

[0133] The first rotating shaft 582 is connected to the drive device 560 via gears and a rotating shaft, and is installed in the housing to prevent hair from getting tangled on the rotating shaft or gears.

[0134] Example 6:

[0135] like Figure 7 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the roller body 571 is inclined from top to bottom from the outer end toward the mounting ring 580, and the axes of the roller bodies 571 on both sides of the mounting ring 580 form an angle of 150-180°.

[0136] Impurities on the hook 220 are entangled with each other. When the rollers 571 on both sides of the mounting ring 580 are at an angle, the cleaning roller 570 provides a lateral force to move towards the roller 571 when separating impurities. This causes impurities that are far from the range of action of the roller 571 to move towards the roller 571. This reduces the number of lateral movement steps of the cleaning roller 570 and can also completely remove impurities from the hook 220, thus improving the cleaning effect of the cleaning roller 570. When the angle is less than 150°, the rollers 571 on both sides of the mounting ring 580 need to be larger, which is not conducive to the cleaning roller 570 extending into the second receiving groove 212.

[0137] Example 7:

[0138] like Figure 1 As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the transmission mechanism 400 further includes: a first transmission tooth 410, a second transmission tooth 420, a third transmission tooth 430, a fourth transmission tooth 440, a fifth transmission tooth 450, a sixth transmission tooth 460, and a clutch assembly 600.

[0139] The first transmission gear 410 and the second transmission gear 420 are movably mounted on the drive shaft 110. The third transmission gear 430 and the fourth transmission gear 440 are coaxially connected. The first transmission gear 410 meshes with the third transmission gear 430, the second transmission gear 420 meshes with the fourth transmission gear 440, the third transmission gear 430 meshes with the fifth transmission gear 450, and the fifth transmission gear 450 meshes with the sixth transmission gear 460. The clutch assembly 600 controls the drive shaft 110 to drive the first transmission gear 410 or the second transmission gear 420 to rotate.

[0140] The clutch assembly 600 controls the drive shaft 110 to drive the first transmission gear 410 or the second transmission gear 420 to rotate. The transmission ratio between the first transmission gear 410 and the third transmission gear 430 is different from the transmission ratio between the second transmission gear 420 and the fourth transmission gear 440, thereby achieving the adaptation of the rotation speed of the crochet hook 220 to the knitting speed of the sock.

[0141] Example 8:

[0142] like Figure 1 Figure 8As shown, this application embodiment provides a thread-cutting device for a sock machine with a uniform thread-cutting function. In addition to the above-mentioned technical features, the clutch assembly 600 further includes:

[0143] Clutch seat 610, mounted on frame 100;

[0144] Drive seat 620 is hinged to clutch seat 610;

[0145] Clutch 630 is mounted on drive shaft 110;

[0146] Roller 640 is mounted on drive seat 620 and abuts against clutch 630;

[0147] The clutch 630 has a first ratchet 631 at one end and a second ratchet 421 at the second transmission gear 420. The first ratchet 631 and the second ratchet 421 are adapted to each other. The clutch 630 has a first limiting part 632 at the other end. The first transmission gear 410 has a first limiting groove 411 adapted to the first limiting part 632. The inner wall of the clutch 630 has a second limiting part. The drive shaft 110 has a second limiting groove 111 adapted to the second limiting part.

[0148] Under normal conditions, the drive seat 620 acts on the clutch 630, causing the first limiting groove 411 to match the first limiting part 632. The drive shaft 110 drives the first transmission gear 410 to rotate. A pneumatic or electric drive device acts on the drive seat 620, causing the drive seat 620 to rotate and act on the clutch 630, thereby moving the clutch 630. This causes the first ratchet 631 to engage with the second ratchet 421, and the drive shaft 110 drives the second transmission gear 421 to rotate. The matching of the second limiting part with the second limiting groove 111 ensures that the clutch 630 and the drive shaft 110 rotate simultaneously.
