Description

Technical Field

[0001] The utility model relates to the field of glove machines, in particular to a wire clamping mechanism of a pair of scissors of a glove machine. Background Art

[0002] The scissors device is an important part of knitting and textile machines such as glove machines and sock knitting machines, and is used to cut the knitting thread so that the knitted gloves, socks and other products can be separated. During the working process of the glove machine, the latch needles continuously stretch and retract: when the latch needles extend, they hook the thread, and when the latch needles retract, the scissors cut the yarn hooked back by the latch needles. The commonly used scissors device usually fixes one scissor blade (commonly called the main scissor blade), makes the other scissor blade rotate (commonly called the auxiliary scissor blade), and drives the rotatable scissor blade to rotate through an actuating device combined with various transmission mechanisms, so that a relative movement is generated between the two scissor blades to achieve the cutting action.

[0003] After the yarn is cut, a wire pressing mechanism is required to press the yarn to prevent the yarn from jumping when it is cut. If the yarn jumps, it is very troublesome to re-string the yarn; therefore, when the scissors device works, a wire pressing mechanism is generally used as an auxiliary. First, the yarn is pressed, and then the scissors cut the yarn. After the yarn is cut, it is still pressed by the wire pressing mechanism so that the yarn can be used for subsequent knitting.

[0004] When controlling the knitting of double-yarn gloves, the above control needs to be performed on two yarns at the same time. The applicant discloses a pair of scissors mechanism of a glove machine in CN220907812U, which controls two yarns through an upper pressing piece, a movable pressing piece, a lower pressing piece, an auxiliary pressing piece, etc.

[0005] However, the above method mainly clamps two yarns by the swing of the movable pressing piece. Even with the assistance of the auxiliary pressing piece, its stability is not ideal when performing the wire clamping action.

[0006] Therefore, the inventor further studies this and develops a wire clamping mechanism of a pair of scissors of a glove machine, and this case is thus produced. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a wire clamping mechanism of a pair of scissors of a glove machine, which improves the stability when clamping two yarns on the premise that only one actuating device drives the wire clamping action.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A wire clamping mechanism of a pair of scissors of a glove machine, comprising

[0010] an upper swing piece and a lower swing piece, one ends of the upper swing piece and the lower swing piece swing under the action of corresponding first and second lever rods, and wire grooves for acting on the yarn are formed on both sides of the other ends.

[0011] The upper pressing piece and the lower pressing piece are fixedly arranged relative to the upper swinging piece and the lower swinging piece, and a wire groove for clamping the yarn is provided on one side of the end part thereof;

[0012] The upper swinging piece, the lower swinging piece, the upper pressing piece and the lower pressing piece are stacked in space;

[0013] An actuating device, the actuating device is linked with the first connecting rod and the second connecting rod, and the first connecting rod and the second connecting rod can drive the first shifting rod and the second shifting rod to drive the corresponding upper swinging piece and lower swinging piece to move, so as to realize the clamping or releasing action of the yarn.

[0014] For the above wire clamping mechanism, on the premise of adopting one actuating device, the upper swinging piece and the lower swinging piece are controlled to move relative to the upper pressing piece and the lower pressing piece, and the two yarns are respectively clamped, so as to ensure the stability during wire clamping.

[0015] Furthermore, the upper swinging piece is linked with the first shifting rod, and the first shifting rod is linked with the first connecting rod; the lower swinging piece is linked with the second shifting rod, and the second shifting rod is linked with the second connecting rod; the upper swinging piece is located above the lower swinging piece.

[0016] Furthermore, the wire clamping mechanism is arranged on the scissors seat, and is sequentially arranged from top to bottom as an upper pressing piece, an upper swinging piece, an upper pressing piece, a spacer, a lower pressing piece, a lower swinging piece, and a lower pressing piece.

[0017] The upper and lower parts of the upper swinging piece and the lower swinging piece are assisted in wire clamping by the corresponding pressing pieces, and the adjacent upper pressing piece and lower pressing piece are isolated by the spacer.

[0018] Furthermore, the upper pressing piece and the lower pressing piece are of sheet-like structures; the upper swinging piece and the lower swinging piece are of L-shaped structures.

[0019] Furthermore, one end of the first shifting rod and the second shifting rod is provided with a groove to be linked with the upper swinging piece and the lower swinging piece, and the other end is provided with a connecting column to be linked with the first connecting rod and the second connecting rod.

[0020] Furthermore, one end of the first connecting rod and the second connecting rod is provided with an L-shaped sliding groove, and the other end is provided with a rack; wherein, the connecting column can slide in the L-shaped sliding groove, the rack is linked with the gear driven by the actuating device, and the first connecting rod and the second connecting rod are arranged in parallel, and the gear is arranged between the racks of the first connecting rod and the second connecting rod.

[0021] The first connecting rod and the second connecting rod are driven by the gear to move alternately, so as to control different wire clamping actions of the upper swinging piece and the lower swinging piece.

[0022] Furthermore, when the first connecting rod and the second connecting rod are driven by the gear:

[0023] When the positions of the first connecting rod and the second connecting rod are at the same height, the upper swinging piece and the lower swinging piece are both in the wire clamping state;

[0024] When the position of the first link is lower than that of the second link, the upper swing piece is in the thread clamping state and the lower swing piece is in the open state;

[0025] When the position of the first link is higher than that of the second link, the upper swing piece is in the open state and the lower swing piece is in the thread clamping state.

[0026] Since the scissors and the thread clamping mechanism are in a stacked state in the vertical direction when the scissors mechanism works, the relative heights of the first link and the second link can be distinguished when they are driven.

[0027] Furthermore, a pair of scissors is arranged between the scissors seat and the thread clamping mechanism, and the scissors include a fixed main scissor blade and a swingable sub-scissor blade.

[0028] The driving structure of the scissors is consistent with the structure of the prior application.

[0029] Furthermore, limiting grooves are formed in the first link and the second link, and limiting bolts fixed on the scissors seat are arranged in the limiting grooves.

[0030] The limiting grooves are used to limit the lifting paths of the first link and the second link.

[0031] After adopting the above scheme, compared with the prior art, the utility model has the following advantages:

[0032] Through the same actuating device, the upper swing piece and the lower swing piece are simultaneously driven to clamp and open the thread, so as to realize the stable control of two yarns. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048] As Figure 7 shown, a thread clamping mechanism of a glove machine scissor, which is used in cooperation with the scissor of the glove machine, mainly includes an upper pressing piece 41, an upper swing piece 11, an upper pressing piece 41, a spacer 6, a lower pressing piece 42, a lower swing piece 12, a lower pressing piece 42, and a spacer 6, which are arranged above the scissor base 9 from top to bottom in sequence, and the main scissor blade 51 and the auxiliary scissor blade 52 of the scissor are located below the lowermost spacer 6; and a first connecting rod 31 and a second connecting rod 32 located on one side of the scissor base 9. Among them, the upper swing piece 11 is pivotally connected to the scissor base 9 and is linked with the first connecting rod 31 through the first lever 21, and the lower swing piece 12 is pivotally connected to the scissor base 9 and is linked with the second connecting rod 32 through the second lever 22. Specifically:

[0049] Wire grooves for making way or clamping the thread are provided on both sides of the ends of the upper swing piece 11 and the lower swing piece 12 that act on the yarn, and wire grooves for clamping the thread are provided on one side of the ends of the upper pressing piece 41 and the lower pressing piece 42 that act on the yarn; and the upper swing piece 11 and the lower swing piece 12 are integrally of an L-shaped structure. Taking the illustrated angle as an example, the other end thereof is vertically arranged relative to the upper pressing piece 41 and the lower pressing piece 42 and is matched with the grooves at the ends of the first lever 21 and the second lever 22. The first lever 21 and the second lever 22 are pivotally connected to the scissor base 9, and a connecting column 23 is further provided thereon, and the connecting column 23 is respectively located in the L-shaped sliding grooves 303 at the tops of the first connecting rod 31 and the second connecting rod 32.

[0050] The first connecting rod 31 and the second connecting rod 32 are arranged in parallel, and racks are provided on their lower halves. A gear 7 is arranged between the racks. Therefore, when the motor 8 drives the gear 7 to rotate back and forth, the first connecting rod 31 and the second connecting rod 32 are relatively lifted and lowered alternately, thereby changing the relative position of the connecting column 23 in the L-shaped chute 303, realizing the swinging of the first lever 21 and the second lever 22, and the first lever 21 and the second lever 22 respectively drive the upper swing piece 11 and the lower swing piece 12 linked to them to swing in the horizontal direction, thereby realizing the opening and closing relative to the upper pressing piece 41 and the lower pressing piece 42.

[0051] Limit slots 302 are also provided on the first connecting rod 31 and the second connecting rod 32. Limit bolts 301 fixed on the scissors seat 9 are arranged in the limit slots 302. The limit slots 302 are used to limit the lifting stroke of the first connecting rod 31 and the second connecting rod 32 when driven by the gear 7.

[0052] In the prior patent, the movable pressing piece is also driven by a lever, and the scissors are driven by a rotating shaft. Since the rotating shaft is close to an ellipse, by opening different through slots on the movable pressing piece and the scissor blade, it can be selected whether they follow the rotation of the rotating shaft. The driving principle of the scissors in the present invention is the same as that of the prior art and will not be elaborated here.

[0053] For the specific wire clamping action of the present invention, refer to Figures 1-6 as shown:

[0054] As Figure 1 , 2 shown, the motor 8 drives the gear 7 to rotate, making the relative height of the first connecting rod 31 lower than that of the second connecting rod 32. In the L-shaped chute 303, the connecting column 23 of the first connecting rod 31 is located at the top of the vertical part of the L-shaped chute 303, and the connecting column 23 of the second connecting rod 32 is located at the closed end of the horizontal part at the bottom of the L-shaped chute 303. The end of the upper swing piece 11 is close to the wire groove of the upper pressing piece 41 located on the right side relatively, and the lower swing piece 12 is also located on the right side at this time. At this time, the wire clamping position two is closed and the wire clamping position one is opened.

[0055] As Figure 3 , 4 shown, the motor 8 drives the gear 7 to rotate, making the relative height of the first connecting rod 31 equal to that of the second connecting rod 32. In the L-shaped chute 303, the connecting columns 23 of the first connecting rod 31 and the second connecting rod 32 are both located in the middle of the vertical part of the L-shaped chute 303. At this time, since the connecting column 23 of the first connecting rod 31 is still in the vertical part of the L-shaped chute 303, and the connecting column 23 of the second connecting rod 32 has moved from the horizontal part to the vertical part, the lower swing piece 12 generates a swinging action driven by the second lever 22. Therefore, the wire clamping position two remains closed, and the wire clamping position one is also closed.

[0056] As Figure 5 , 6As shown, the motor 8 drives the gear 7 to rotate, making the relative height of the first connecting rod 31 equal to that of the second connecting rod 32. In the L-shaped chute 303, the connecting column 23 of the first connecting rod 31 is located at the closed end of the horizontal part at the bottom of the L-shaped chute 303, and the connecting column 23 of the second connecting rod 32 is located at the top of the vertical part of the L-shaped chute 303. The connecting column 23 of the second connecting rod 32 still remains in the vertical part of the L-shaped chute 303, and the connecting column 23 of the first connecting rod 31 moves from the vertical part of the L-shaped chute 303 to the closed end of the horizontal part. Therefore, the first lever 21 generates a lateral swing, thereby opening the second yarn clamping position, while the first yarn clamping position remains closed.

[0057] The above "first / second lever, first / second connecting rod, first / second yarn clamping position", etc. are only for relative distinction in the clamping state of two yarns, not absolute limitations. Any non-substantive modification using the present invention shall belong to the act of infringing the protection scope of the present invention.
