Description

Technical Field

[0001] The utility model relates to the technical field of weaving equipment, and more specifically to an elastic sinker with a double-piece structure. Background Art

[0002] Computerized flat knitting machine is a double needle plate latch needle weft knitting machine. Its cam device is like a set of flat cams. The needle feet of the knitting needle can enter the groove of the cam, move the cam, force the knitting needle to make regular up and down movements in the needle groove of the needle plate, and through the action of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue, and withdraws the needle tongue to hang on the needle bar; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil, while the original coil is out of the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting are connected to each other to form a knitted fabric.

[0003] At present, most of the elastic sinkers used in braiding machines adopt an integrated design, which has great limitations. Since the amplitude of the elastic sinker is small, the downward pressure is greatly limited; if the elastic sinker swings too much, its own stability will also be affected.

[0004] In view of the above-mentioned deficiencies of the existing elastic sinkers, the applicant adheres to the spirit of research innovation and excellence, combines production practice, and uses professional and scientific methods to propose a practical solution, and therefore files this application.

[0007] Specifically, the upper barb is disposed at the end of an elastic arm at the bottom of the pusher. The elastic arm provides a certain rebound amplitude while providing downward pressure to avoid crushing the yarn and the coil.

[0008] Preferred solution: The knitting needle pressing block is provided with a front cylinder and a rear cylinder. The front cylinder is arranged in the first straight slot hole and can move back and forth along the first straight slot hole. The rear cylinder is located below the sliding rod at the rear end of the first straight slot.

[0009] Preferred solution: The knitting needle pressing block is provided with a front cylinder and a rear cylinder. Both the front cylinder and the rear cylinder are arranged in the first straight slot hole and can move back and forth inside the first straight slot hole.

[0010] Specifically, support cylinders are provided at both the front and rear sections of the knitting needle pressing block. The support cylinders, the front cylinder, and the rear cylinder between the two knitting needle pressing blocks abut against each other. The cylinders between the two knitting needle pressing blocks abut against each other, always maintaining a certain gap, so as to allow the elastic sinker to displace.

[0011] Specifically, a positioning round hole for the steel wire to pass through is provided at the front section of the knitting needle pressing block, and a quick-detachable hole for the steel wire to pass through is provided at the rear section of the knitting needle pressing block.

[0012] Specifically, a U-shaped rotating slot is provided on one inner side of the knitting needle pressing block. The circular rotating part is inserted into the rotating slot. The yarn pressing part swings around the center of the rotating part. The rotating slot is a bent metal strip.

[0013] Specifically, the front end of the yarn pressing part extends into the slot at the front end of the needle plate, and a high-tooth piece is closely arranged on one side of the yarn pressing part. The high-tooth piece can abut against one side of the front end of the yarn pressing part. Cooperating with the slot at the front end of the needle plate, the hook at the front end of the yarn pressing part can be limited.

[0014] Specifically, the contact surface between the bottom of the knitting needle pressing block and the knitting needle is 7 to 15 mm, increasing the contact area between the two, enabling the knitting needle pressing block to press the knitting needle more stably. When the knitting needle displaces, the path is more accurate.

[0015] Compared with the prior art, the beneficial effects are as follows:

[0016] This application adopts an elastic sinker with a two-stage design. The pusher and the yarn pressing part can better realize their respective functions. The pusher is connected to the lower barb of the yarn pressing part through the upper barb at the end of the elastic arm, and the upper barb drives the yarn pressing part to swing. The elastic arm plays a role in rebounding to avoid crushing the yarn coil. The yarn pressing part can swing around the center of the rotating part and uses the front groove to realize the function of pressing the yarn. Compared with the traditional sinker, the position of pressing the yarn is lower, the effect of pressing the yarn is better, and more complex knitting actions can be realized; a U-shaped rotating slot is welded on the knitting needle pressing block of this application to realize the function of limiting the rotation angle of the yarn pressing part in the rotating slot. The rotating slot is welded on the inner wall of a knitting needle pressing block, and its processing method is relatively simple and fast, the structural design is more reasonable, and the whole is more firm.
