Description

Technical Field

[0001] This utility model belongs to the field of sock machine structure technology, and relates to a sock machine crank handle base. Background Technology

[0002] A sock knitting machine is a machine used to weave socks. Due to the special shape of socks, sock knitting machines differ significantly from ordinary textile machinery, such as sewing machines. Currently, circular sock knitting machines are widely used. The sock knitting machine's bell-shaped structure is located at the crank handle base and the machine disc, requiring a side-mounted motor and transmission structure for drive, and a brake for locking. However, in current sock knitting machine crank handle bases, the brake mechanism is far from the opening between the gear set and the belt. The gear set brake lock requires a significant pre-deceleration angle, and the belt is prone to slippage when the pin is locked, requiring multiple gear rotations to achieve locking. This results in low brake locking efficiency and a slow response time. Therefore, it is urgently necessary to design a sock knitting machine crank handle base that overcomes these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, Chinese patent discloses an adjustable sock machine positioning operation crank [application number: 202021093395.1]. This adjustable sock machine positioning operation crank includes a crank handle movable device. A positioning sleeve is fixedly connected to the left side of the inner wall of the crank handle movable device. A rotating rod is sleeved inside the positioning sleeve. The left end of the rotating rod is located outside the crank handle movable device. The right end of the rotating rod is fixedly connected to one end of a connecting rod. The other end of the connecting rod is rotatably connected to the crank handle. The top of the positioning sleeve is movably connected to a conductive sheet through a first return spring. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a sock machine crank handle holder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sock knitting machine crank handle base includes a crank handle base body, a sock knitting machine disc body above the crank handle base body, a sock knitting machine crank handle on the crank handle base body, a horn tube mounting channel and a motor shaft mounting channel within the sock knitting machine disc body, a belt gear transmission component between the horn tube mounting channel and the motor shaft mounting channel, an anti-slip brake assembly on the crank handle base body, and an obtuse angle between the line connecting the centers of the horn tube mounting channel and the motor shaft mounting channel and the anti-slip brake assembly, and an obtuse angle between the line connecting the centers of the horn tube mounting channel and the motor shaft mounting channel and the sock knitting machine crank handle.

[0007] In the aforementioned sock machine crank handle base, the anti-slip brake assembly includes a brake cylinder mounted on the crank handle base. The brake cylinder is provided with a brake locking pin that can reciprocate linearly along one end of the horn tube mounting channel, and the position of the brake locking pin corresponds to that of the belt gear transmission component.

[0008] In the aforementioned sock machine crank handle base, the belt gear transmission component includes a belt transmission component disposed between the horn tube mounting channel and the motor shaft mounting channel, and the crank handle base body is provided with a locking pin, which engages with a brake locking pin.

[0009] In the aforementioned sock machine crank handle base, the belt transmission component includes a horn tube rotating gear disposed in the horn tube mounting channel, a motor shaft rotating gear disposed in the motor shaft mounting channel, a transmission belt disposed between the horn tube rotating gear and the motor shaft rotating gear, and the opening between the transmission belt and the horn tube rotating gear corresponds to the position of the brake locking pin.

[0010] In the aforementioned sock machine crank handle base, the locking pin includes a locking pin chuck located at the bottom of the horn cylinder rotating gear. The locking pin chuck has a locking pin slot, which is open-type. The locking pin slot corresponds to the position of the brake locking pin and is matched in shape.

[0011] In the aforementioned sock machine crank handle seat, a sealing reinforcement is provided between the crank handle seat body and the sock machine disc body, and the sealing reinforcement is connected to the brake cylinder.

[0012] In the aforementioned sock machine crank handle base, the sealing reinforcement includes an upper sealing reinforcement plate disposed between the crank handle base body and the sock machine disc body. One end of the upper sealing reinforcement plate is connected to the crank handle base body, and the other end is connected to the sock machine disc body. The upper sealing reinforcement plate is fixed to the brake cylinder by bolts.

[0013] In the aforementioned sock machine crank handle holder, the crank handle holder body is provided with a belt guide, and the transmission belt is positioned and shaped to correspond with the belt guide.

[0014] In the aforementioned sock machine crank handle base, the belt guide part includes a belt guide seat disposed on the crank handle base body, the belt guide seat having a guide groove therein, and the transmission belt passing through the belt guide seat.

[0015] In the aforementioned sock machine crank handle holder, the crank handle holder body is provided with a brake adjustment and fixing groove, the brake adjustment and fixing groove is arc-shaped, the brake cylinder is provided with an arc-shaped connecting plate, and the arc-shaped connecting plate is slidably engaged with the brake adjustment and fixing groove.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model offsets the motor shaft mounting channel, thereby rotating the installation angle of the belt gear transmission component, and aligns the anti-slip brake assembly closer to the opening between the gear and belt parts in the belt gear transmission component. When the sock machine motor is operating in both forward and reverse directions, the anti-slip brake assembly locks itself with a locking pin while the belt of the belt gear transmission component is in a taut position. This ensures that the anti-slip brake assembly can be better and faster inserted into the belt gear transmission component to complete the locking, preventing slippage of the anti-slip brake assembly during braking. The braking locking efficiency is higher, and the response speed is more sensitive.

[0018] 2. The brake adjustment fixing groove in this utility model is used to house and fix the arc-shaped connecting plate and the brake cylinder. The position of the brake cylinder can be finely adjusted through the cooperation between the arc-shaped connecting plate and the brake adjustment fixing groove, which makes it easier for the brake locking pin to confirm a more reasonable position for brake locking and is convenient to adjust.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a sock knitting machine crank handle base includes a crank handle base body 1, a sock knitting machine disc body 2 above the crank handle base body 1, a sock knitting machine crank handle 3 on the crank handle base body 1, a horn tube mounting channel 4 and a motor shaft mounting channel 5 inside the sock knitting machine disc body 2, a belt gear transmission component 6 between the horn tube mounting channel 4 and the motor shaft mounting channel 5, and an anti-slip brake component 7 on the crank handle base body 1. The angle between the center connecting line of the horn tube mounting channel 4 and the motor shaft mounting channel 5 and the anti-slip brake component 7 is an obtuse angle, and the angle between the center connecting line of the horn tube mounting channel 4 and the motor shaft mounting channel 5 and the sock knitting machine crank handle 3 is also an obtuse angle.

[0027] In this embodiment, the horn mounting channel 4 is used to house and fix the sock machine horn structure, and the motor shaft mounting channel 5 is used to house and fix the sock machine motor shaft structure. The sock machine motor drives the belt gear transmission component 6 to operate. The sock machine crank handle 3 can rotate the sock machine to a suitable angle for maintenance, making it more convenient to maintain the sock machine. The sock machine disc body 2 is used to connect and fix the crank handle seat 1 and the sock knitting equipment. The anti-slip brake component 7 can lock the operating belt gear transmission component 6 to achieve the purpose of braking. The motor shaft mounting channel 5 is offset to rotate the mounting angle of the belt gear transmission component 6, and the anti-slip brake component 7 is arranged closer to the opening between the gear part and the belt part in the belt gear transmission component 6. When the sock machine motor is working in forward and reverse directions, the anti-slip brake component 7 locks the belt gear transmission component 6 with the belt in the taut position, ensuring that the anti-slip brake component 7 can be inserted into the belt gear transmission component 6 better and faster to complete the locking, avoiding slippage of the anti-slip brake component 7 during braking. The braking locking efficiency is higher and the response speed is more sensitive.

[0028] Combination Figure 1-4 As shown, the anti-slip brake assembly 7 includes a brake cylinder 8 disposed on the crank handle seat 1. The brake cylinder 8 is provided with a brake locking pin 9 that can reciprocate linearly along one end of the horn tube mounting channel 4, and the brake locking pin 9 corresponds to the position of the belt gear transmission component 6.

[0029] Specifically, the motor shaft mounting channel 5 is offset, thereby rotating the installation angle of the belt gear transmission component 6, and the brake cylinder 8 is positioned closer to the opening between the gear part and the belt part in the belt gear transmission component 6. When the sock machine motor is working in both forward and reverse directions, the brake cylinder 8 is activated, and the brake locking pin 9 is moved. The brake locking pin 9 locks itself when the belt of the belt gear transmission component 6 is in a taut position, ensuring that the brake locking pin 9 can be inserted into the belt gear transmission component 6 better and faster to complete the locking, avoiding slippage of the brake locking pin 9 during braking, resulting in higher brake locking efficiency and more sensitive response speed.

[0030] Combination Figure 1-4 As shown, the belt gear transmission component 6 includes a belt transmission component 10 disposed between the horn tube mounting channel 4 and the motor shaft mounting channel 5, and a locking pin 11 is provided in the crank handle seat 1, which is engaged with the brake locking pin 9.

[0031] In this embodiment, the belt transmission component 10 plays a transmission role, and the locking pin 11 engages with the brake locking pin 9 to achieve the purpose of brake locking.

[0032] The belt conveyor 10 includes a horn tube rotating gear 12 disposed in the horn tube mounting channel 4, a motor shaft rotating gear 13 disposed in the motor shaft mounting channel 5, a transmission belt 14 disposed between the horn tube rotating gear 12 and the motor shaft rotating gear 13, the opening between the transmission belt 14 and the horn tube rotating gear 12 corresponding to the position of the brake locking pin 9, and the locking pin locking component 11 including a locking pin chuck 15 disposed at the bottom of the horn tube rotating gear 12, the locking pin chuck 15 having a locking pin groove 16, the locking pin groove 16 being open, the locking pin groove 16 corresponding to the position of the brake locking pin 9 and matching its shape.

[0033] In this embodiment, the motor shaft rotating gear 13 is connected to the rotating shaft of the sock machine motor. When the sock machine motor rotates forward and backward, it can drive the motor shaft rotating gear 13 to rotate. Through the transmission belt 14, it synchronously drives the horn tube rotating gear 12 to rotate, thereby driving the sock machine horn tube structure to rotate forward and backward. The position of the brake locking pin 9 is changed, and it is placed closer to the opening between the transmission belt 14 and the horn tube rotating gear 12. When the sock machine motor rotates forward and backward, there will be a gap between the belt and the gear. The transmission belt 14 will be in a state of half a turn of tension on one side and half a turn of looseness on the other side. By placing the brake locking pin 9 closer to the opening on the tensioned side of the transmission belt 14, the transmission belt 14 is in a tensioned state when the brake is locked. The engagement locking accuracy is high, and the brake locking pin 9 does not need to lock for too long in advance. This ensures that the brake locking pin 9 can be better and faster inserted into the locking pin slot 16 in the locking pin chuck 15 to complete the locking, avoiding the brake locking pin 9 from slipping during braking. The brake locking efficiency is higher and the response speed is more sensitive.

[0034] A sealing reinforcement 17 is provided between the crank handle base 1 and the sock machine disc 2, and the sealing reinforcement 17 is connected to the brake cylinder 8.

[0035] In this embodiment, the sealing reinforcement 17 is used to seal and reinforce the crank handle seat 1 and the sock machine disc 2, and at the same time, it can connect and fix the upper part of the brake cylinder 8, resulting in better stability.

[0036] The sealing reinforcement component 17 includes an upper sealing reinforcement plate 18 disposed between the crank handle seat 1 and the sock machine disc 2. One end of the upper sealing reinforcement plate 18 is connected to the crank handle seat 1, and the other end is connected to the sock machine disc 2. The upper sealing reinforcement plate 18 is fixed to the brake cylinder 8 by bolts.

[0037] In this embodiment, the upper sealing and reinforcing plate 18 is used to seal and reinforce the crank handle seat 1 and the sock machine disc 2, and at the same time, it can connect and fix the upper part of the brake cylinder 8, resulting in better stability. The upper sealing and reinforcing plate 18 and the brake cylinder 8 are fixed with bolts, making disassembly and assembly simple and convenient.

[0038] Combination Figure 2-3 As shown, the crank handle base 1 is provided with a belt guide 19, and the transmission belt 14 is positioned and matched with the belt guide 19.

[0039] In this embodiment, during the transmission process, the belt guide 19 can guide the belt 14 to avoid jumping during the transmission process, resulting in higher transmission efficiency and greater stability.

[0040] Combination Figure 3As shown, the belt guide 19 includes a belt guide seat 20 disposed on the crank handle seat 1, the belt guide seat 20 is provided with a guide groove 21, and the transmission belt 14 passes through the belt guide seat 20.

[0041] In this embodiment, during the transmission process, the belt 14 can be guided by the belt guide seat 20 and the guide groove 21 to avoid jumping during the transmission process, resulting in higher transmission efficiency and greater stability.

[0042] Combination Figure 2-4 As shown, the crank handle seat 1 is provided with a brake adjustment and fixing groove 22, which is arc-shaped. The brake cylinder 8 is provided with an arc-shaped connecting plate 23, which slides in conjunction with the brake adjustment and fixing groove 22.

[0043] In this embodiment, the brake adjustment fixing groove 22 is used to house and fix the arc-shaped connecting plate 23 and the brake cylinder 8. The position of the brake cylinder 8 can be finely adjusted through the cooperation between the arc-shaped connecting plate 23 and the brake adjustment fixing groove 22, so that the brake locking pin 9 can confirm a more reasonable position for brake locking and the adjustment is convenient.

[0044] The working principle of this utility model is as follows:

[0045] The horn mounting channel 4 is used to house and fix the sock machine horn structure, and the motor shaft mounting channel 5 is used to house and fix the sock machine motor shaft structure. The sock machine motor drives the belt and gear transmission component 6 for operation. The sock machine crank handle 3 can rotate the sock machine to a suitable angle for maintenance, making maintenance more convenient. The sock machine disc 2 connects and fixes the crank handle seat 1 and the sock machine knitting equipment. The motor shaft rotating gear 13 is connected to the rotating shaft of the sock machine motor. When the sock machine motor rotates forward and backward, it drives the motor shaft rotating gear 13 to rotate, which synchronously drives the horn rotating gear 12 to rotate via the transmission belt 14, thereby driving the sock machine horn structure to rotate forward and backward. (Brake / Brake function is also mentioned.) The position of the locking pin 9 is changed, placing it closer to the opening between the transmission belt 14 and the horn-shaped rotating gear 12. When the sock machine motor rotates forward and backward, the transmission belt 14 will be in a state of half-turn tension on one side and half-turn slack on the other. By placing the brake locking pin 9 closer to the tensioned side of the transmission belt 14, the transmission belt 14 is in a taut state when the brake is locked, resulting in high engagement and locking precision. The brake locking pin 9 does not need to lock for too long in advance, ensuring that the brake locking pin 9 can be better and faster inserted into the locking pin slot 16 in the locking pin chuck 15 to complete the lock, preventing the brake locking pin 9 from slipping during braking. This results in higher brake locking efficiency and a more sensitive response speed.

[0046] During transmission, the conveyor belt 14 is guided by the belt guide seat 20 and guide groove 21, preventing the conveyor belt 14 from jumping during transmission, resulting in higher transmission efficiency and greater stability.

[0047] The brake adjustment fixing groove 22 is used to house and fix the arc-shaped connecting plate 23 and the brake cylinder 8. The position of the brake cylinder 8 can be finely adjusted through the cooperation between the arc-shaped connecting plate 23 and the brake adjustment fixing groove 22, so that the brake locking pin 9 can confirm a more reasonable position for brake locking and the adjustment is convenient.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
