Description

Technical Field

[0001] This invention relates to the field of knitting machine technology, and in particular to a knitting machine with a high-efficiency yarn feeding function. Background Technology

[0002] A knitting machine is used to weave multiple yarns to form the desired pattern or design. A knitting machine generally consists of a yarn feeding section, a guiding section, and a knitting section. The yarn feeding section feeds the yarn, and the yarn passes through the guiding section into the knitting section to be woven into shape.

[0003] In the prior art, such as Chinese Patent Publication No. CN214059518U, a corrective feeding mechanism for a knitting machine is disclosed, including a base and a frame. A bobbin is mounted on the upper end of the base through a dustproof box. A dustproof cover is mounted on the upper end of the dustproof box. A first bearing seat is mounted on the top inside of the dustproof cover. A second bearing seat is mounted on the bottom inside of the dustproof box. The bobbin rotates inside the dustproof box through the first and second bearing seats. A yarn outlet hole is opened on one side of the dustproof box. The frame is fixedly mounted on one side of the upper end of the base. Sliding grooves are symmetrically opened on both sides of the frame. A sliding block is sleeved on the outside of the sliding groove. A driving component is mounted on one end of the sliding block. A guide plate is mounted on the lower end of the sliding block.

[0004] The above-mentioned patent has the following shortcomings: Since the yarn feeding speed of the braiding part is different and there is also intermittent yarn feeding, when the yarn feeding speed decreases or stops suddenly, the drum will continue to rotate due to inertia, causing the yarn between the yarn feeding part and the braiding part to loosen. The loose yarn will bend downward, causing entanglement and friction with other parts of the machine, which requires re-sorting and unwinding, reducing production efficiency.

DETAILED DESCRIPTION

[0035] The technical solutions of the present application will be further described in detail below in combination with specific embodiments.

[0036] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application. Example 1:

[0037] A knitting machine with high-efficiency thread feeding function, such as Figures 1-9As shown, including the mounting seat 1, the top of the mounting seat 1 is respectively provided with a weaving mechanism 2 for weaving and a wire feeding mechanism 3 for feeding wire to the weaving mechanism 2. In the embodiment, the specific type of the weaving mechanism 2 is not limited, which is prior art and mature, and the embodiment does not make creative labor, so it is not described.

[0038] The wire feeding mechanism 3 includes a mounting frame 4 fixed to the outer wall of the top of the mounting seat 1 by bolts and a sliding block 5 slidingly connected to the inner wall of the mounting frame 4 by a guide rod 7. The upper portion of the sliding block 5 is rotatably connected with a wire drum fixing assembly 11 for fixing the wire drum through a shaft 1.

[0039] The outer wall of the guide rod 7 is sleeved with a spring 1, and the outer wall of the shaft 1 is connected with a gear 8 through a key. The bottom outer wall of the mounting frame 4 is fixed with a rack 10 which can engage with the gear 8 through bolts.

[0040] When the device is used, the wire drum can be fixed through the wire drum fixing assembly 11, and then the end of the yarn is fed into the weaving mechanism 2. When weaving, the weaving mechanism 2 takes up the yarn, so that the wire drum and the wire drum fixing assembly 11 move by pulling the yarn, so that the sliding block 5 slides, the spring 1 is compressed, and the gear 8 and the rack 10 are separated, the wire drum fixing assembly 11 can rotate, so that the yarn is unwound by the rotation of the wire drum fixing assembly 11. When the weaving mechanism 2 stops, the yarn loses the pulling force of the yarn taking up at this time, so that the sliding block 5 is rebounded by the elastic force of the spring 1, so that the gear 8 and the rack 10 are engaged, and the wire drum is locked at this time.

[0041] The device, by setting the sliding block 5, the gear 8 and the rack 10 and other components, can make the gear 8 and the rack 10 separate by the pulling force of the weaving mechanism 2 taking up the yarn, so as to ensure reliable wire feeding, and the gear 8 and the rack 10 can be engaged by the elastic force of the spring 1 when the weaving mechanism 2 stops, so that the wire drum fixing assembly 11 is locked instantaneously, so as to overcome the defect that the wire drum fixing assembly 11 continues to rotate and the yarn is loose due to inertia, and the reliability of use is increased.

[0042] In order to solve the fixing problem; as Figure 3 、 4 As shown, the wire drum fixing assembly 11 includes a hollow cylinder 12 and a plurality of expansion blocks 13 slidingly connected to the radial direction of the hollow cylinder 12. The hollow cylinder 12 is slidingly connected with a slide column 15 in the axial direction, and the outer wall of the slide column 15 is rotatably connected with a plurality of connecting rods 16, and the other end of the connecting rod 16 is rotatably connected to the side wall of the expansion block 13.

[0043] When the slide column 15 rises and falls, it can drive the expansion block 13 to slide through the connecting rod 16, so as to achieve clamping and fixing or loosening of the hollow part of the wire drum.

[0044] The bottom of the slide column 15 is buckled with spring two 14, the other end of spring two 14 is buckled on the inner wall of slide column 15, the top of slide column 15 is rotatably connected with cam 18 through connecting shaft 19, cam 18 is matched with the end face of hollow cylinder 12, and the outer wall of the protruding part of cam 18 is provided with flat mouth 17.

[0045] And the outer wall of connecting shaft 19 is fixed with handle 20.

[0046] When fixing the wire drum, the handle 20 can be rotated, the handle 20 drives the cam 18 to rotate through the connecting shaft 19, so that the slide column 15 moves under the action of the pulling force of spring two 14, so that a plurality of expansion blocks 13 move outward through the connecting rod 16, and the wire drum is fixed, when it is needed to take and place the wire drum, the handle 20 can be rotated, so that the flat mouth 17 is in contact with the hollow cylinder 12, so that the slide column 15 moves upward, and the expansion blocks 13 move inward through the connecting rod 16.

[0047] The device can realize clamping and loosening of the wire drum by rotating the handle 20, thereby increasing the convenience of use, and the flat mouth 17 can automatically lock the matching position of the cam 18 and the hollow cylinder 12, so that the loosening state is maintained, thereby facilitating taking and placing the drum.

[0048] In order to solve the problem of tensioning, as shown in the figure, Figure 5 The bottom of the hollow cylinder 12 is fixed with transition shaft 21, the transition shaft 21 is rotatably connected with shaft one 9, and the transition shaft 21 and shaft one 9 are buckled with volute spring 22.

[0049] The device, by setting shaft one 9, transition shaft 21 and volute spring 22, when the hollow cylinder 12 is rotated by the pulling force, due to the resistance of the rotation of shaft one 9, the volute spring 22 will be deformed, so that when the knitting mechanism 2 stops feeding, the hollow cylinder 12 has a reverse rotation driving force, so that the yarn can be reliably tensioned.

[0050] Because the tensioning force needs to match the feeding speed, that is, when the feeding speed is fast, in order to avoid the wire harness from being broken due to large tensile stress, the required yarn tension is small, and when the feeding speed is slow, the required yarn tension is relatively large, so in order to solve the automatic tensioning problem, as shown in the figure, Figure 6 , 7 The inner wall of the sliding block 5 is rotatably connected with shaft one 9, and the inner wall of the sliding block 5 is slidably connected with friction block 26 in contact with shaft one 9, the side wall of the friction block 26 is fixed with permanent magnet 25 through bolts, and the inner wall of the sliding block 5 is fixed with electromagnet 24 matched with permanent magnet 25.

[0051] When the take-up speed of the knitting mechanism 2 is fast, a relatively strong current is passed through the electromagnet 24 at this time, so that the magnetic attraction between the electromagnet 24 and the permanent magnet 25 is increased, thereby cooperating with the elastic force of the spring 23 on the friction block 26, so that the reasonable reduction of the friction block 26 is caused, so that the contact pressure between the friction block 26 and the shaft 9 is reduced, the rotation resistance of the shaft 9 is reduced, and the tension of the yarn is reduced, and vice versa.

[0052] The bottom outer wall of the sliding block 5 is fixed with a stator winding 27 through a bolt, the outer wall of the shaft 9 is fixed with a rotor core 28 cooperating with the stator winding 27, and the output terminal of the stator winding 27 is connected to the input terminal of the electromagnet 24 through a wire.

[0053] When the take-up speed of the knitting mechanism 2 is fast, the rotation speed of the shaft 9 is also relatively fast, so that the induced current in the stator winding 27 is increased, and vice versa.

[0054] The device can control the contact pressure of the friction block 26 and the shaft 9 by using the magnetic attraction between the electromagnet 24 and the permanent magnet 25, thereby controlling the tension of the yarn, and at the same time, through the electromagnetic induction of the stator winding 27 and the rotor core 28, the take-up speed can be inducted and the electromagnet 24 can be driven and controlled, thereby realizing the function of self-adaptive adjustment of the tension according to the take-up speed.

[0055] The embodiment is used, the line cylinder is fixed through the line cylinder fixing assembly 11, then the end of the yarn is sent into the knitting mechanism 2, when knitting, the knitting mechanism 2 takes the line, so that the line cylinder and the line cylinder fixing assembly 11 are moved by the yarn pulling, so that the sliding block 5 slides, the spring one 6 is compressed, and the gear 8 is separated from the rack 10, the line cylinder fixing assembly 11 can rotate, so that the yarn is unwound by the rotation of the line cylinder fixing assembly 11, when the knitting mechanism 2 stops, the yarn loses the pulling force of taking the line, so that the sliding block 5 is rebounded by the elastic force of the spring one 6, so that the gear 8 is engaged with the rack 10, and the line cylinder is locked, when the line cylinder is fixed, the handle 20 can be rotated, the handle 20 drives the cam 18 to rotate through the connecting shaft 19, so that the sliding column 15 moves under the action of the pulling force of the spring two 14, so that the plurality of expansion blocks 13 move outward through the connecting rod 16, and the line cylinder is fixed, when the line cylinder needs to be taken, the handle 20 can be rotated, so that the flat mouth 17 contacts the hollow cylinder 12, so that the sliding column 15 moves upward, and the expansion block 13 moves inward through the connecting rod 16, when the knitting mechanism 2 takes the line at a high speed, the rotation speed of the shaft one 9 is relatively high, so that the induced current in the stator winding 27 increases, and vice versa. When the knitting mechanism 2 takes the line at a high speed, relatively strong current can be input into the electromagnet 24, so that the magnetic attraction between the electromagnet 24 and the permanent magnet 25 increases, so that the elastic force of the spring three 23 to the friction block 26 is matched, so that the reasonable of the friction block 26 is reduced, the contact pressure between the friction block 26 and the shaft one 9 is reduced, the rotation resistance of the shaft one 9 is reduced, and the tension of the yarn is reduced. Conversely, it is increased. Embodiment 2:

[0057] The bottom of the guide ring 32 is rotatably connected with a lock hook 33 for blocking the opening of the guide ring 32 through a hinged shaft 34, and a torsional spring is arranged at the rotatable connection of the hinged shaft 34 and the guide ring 32.

[0058] The device can guide yarn through the setting of the guide ring 32, thereby increasing the precision of the yarn feeding. Meanwhile, the height between the threaded rod 30 and the threaded cylinder 31 can be adjusted through rotation, so that the guide position can be adjusted according to the yarn feeding position. The movable lock hook 33 can make the yarn pass in and out of the guide ring 32 at will, thereby increasing the convenience.
