Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a scissor device for a glove knitting machine. Background Art

[0002] The scissor mechanism is a crucial component of knitting textile machinery, such as glove and hosiery machines. It is used to cut the yarn and separate the finished gloves, socks, and other products. During the operation of the glove machine, the yarn is hooked by a knife and cut simultaneously with the scissor mechanism. After cutting, the yarn must be clamped to prevent thread jumps.

[0003] The scissor mechanism can be divided into a mobile scissor mechanism that moves with the machine head and a fixed scissor mechanism fixed at both ends of the needle bed. The fixed scissor mechanism generally works by driving a connecting rod with an electromagnet to push out the scissors. The yarn feeder then passes through the machine head, and the movement of the scissors causes them to descend, cutting and clamping the yarn (the bottom of the scissors is inclined, with the lower side for cutting the yarn and the higher side and rubber block for clamping the yarn).

[0004] However, in this method, the rubber is easily worn and is not easy to clamp when using spandex thread; and the linkage method through the machine head is not flexible enough.

[0005] Therefore, the inventor conducted further research and developed a scissor device for a glove machine, which resulted in the present invention. Utility Model Content

[0006] The purpose of the utility model is to provide a glove knitting machine scissor device, which makes the glove knitting machine scissor mechanism more stable when clamping the thread and has a more flexible control method.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A scissor device for a glove machine, comprising

[0009] A scissor element, which moves up and down relative to the needle mouth, and its blade can cut the yarn when it descends;

[0010] The hook knife component follows the scissor component to rise and fall, and a gap is left between the hook knife component and the scissor component;

[0011] The clamping element is relatively fixed in position and cooperates with the hook knife element to clamp the yarn;

[0012] Actuating element, the actuating element independently drives the scissor element and the hook knife element to realize the lifting action.

[0013] The aforementioned needle mouth is the space for the front and rear needle beds to hook the thread and eat the yarn, which is distributed between the two needle beds; in this scheme, the way the scissors element cuts the thread is consistent with the existing technology, both of which are through the cooperation of a movable blade and a fixed blade. The difference is that an additional hook knife element and a clamping element are provided to clamp the yarn after cutting, and the scissors element and the hook knife element are driven by a separate actuator element.

[0014] Furthermore, the scissor element and the hook knife element are an integrated structure.

[0015] The hook knife and scissors can be machined on the end of the same part, so that the scissors element and the hook knife element can move synchronously.

[0016] Furthermore, the relative height of the blade of the scissors element is lower than the lower bottom edge of the hook knife element.

[0017] Furthermore, the clamping element is sleeved around the hook knife element and passes through the gap between the scissor element and the hook knife element.

[0018] Furthermore, the hook knife component includes two hook knives, and a gap is left between the hook knives.

[0019] Leaving a gap between the two hook knives can better control the thickness of the yarn and freely adjust the clamping force to prevent the problem of yarn breakage or loose clamping.

[0020] Further, the bottoms of the two hook knives and the scissors element are inclined from high to low, and the blade of the scissors element for cutting the yarn is at the lowest position.

[0021] The relative height is based on the working state of the scissor device.

[0022] Furthermore, the actuating element includes a motor, the motor drives the cam to rotate, and the cam drives the connecting rod element to drive the scissor element and the hook knife element to perform lifting movements.

[0023] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0024] By adopting an independent driving mode, the linkage structure of the fixed scissors device can be simplified, and the driving is more flexible. At the same time, through the cooperation of the scissors and the hook knife, the wire clamping performance is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 、 2 As shown, a scissor device for a glove machine includes a pair of scissors 1 and a hook knife 2. The scissors 1 and the hook knife 2 are extended from the same driving rod 3. In this embodiment, the scissors 1 have an independent end, and the hook knife 2 has two parallel ends, which can be regarded as two hook knives 2, and there is a gap between the two hook knives 2 and between the hook knife 2 and the scissors 1. In this embodiment, a limit seat 4 is provided around the hook knife 2, that is, the hook knife 2 rises and falls in the limit seat 4, and a groove is further provided in the middle of the limit seat 4 to cooperate with the hook knife 2 to clamp the line; at the same time, the structures of the ends of the scissors 1 and the hook knife 2 are consistent, so Figure 2 As a reference, the bottoms of the two hook knives 2 and the one scissors 1 are tilted from high to low, and the blade of the scissors 1 on the far right for cutting yarn is at the lowest position.

[0033] That is, when hooking the thread, the hook knife 2 and the scissors 1 extend upward from the needle hole relative to the glove machine needle bed 9 (refer to Figure 3 ), after hooking the yarn, they retreat together to the limit seat 4, the scissors 1 are used to cut the yarn, and the hook knife 2 clamps the yarn.

[0034] The above action is achieved by arranging a motor 5 on the frame 8. The motor 5 drives the cam 6 (driving wheel) to rotate. A driven rod is provided on the side wall of the cam 6. The driven rod is linked with the second connecting rod 7. At the same time, one of the rods of the second connecting rod 7 is pivotally connected to the frame 8, and the end of the other rod is linked with the driving rod 3. Therefore, through the drive of the motor 5, the rotation of the cam 6 is converted into the lifting and lowering of the driving rod 3.

[0035] The above-mentioned scissors 1 device can be set according to specific needs, and a pair of scissors 1 can be set on the left and right sides of the glove machine for the front and rear needle beds 9 respectively.

[0036] The above are only specific embodiments of the present invention. At the same time, all words such as "upper, lower, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
