Description

Technical Field

[0001] The utility model relates to the technical field of weft knitting machines, in particular to a circular weft knitting machine. Background Art

[0002] The main mechanisms of the weft knitting machine are the yarn feeding mechanism, weaving mechanism, pulling mechanism, transmission mechanism, auxiliary mechanism and frame. Some jacquard weft knitting machines are also equipped with a needle selection mechanism. The production process of the weft knitting machine is simple, and the yarn used can be directly woven on the machine without going through the preparation process.

[0003] For example, a circular weft knitting machine with publication number CN219731235U includes a machine body and a weft knitting part. Four telescopic rods are fixedly connected to the upper surface of the machine body. The telescopic part of the telescopic rod is sleeved with a spring. A finished product collecting component is arranged in the machine body. The machine body has the function of offsetting the vibration generated when the weft knitting part is working well, and the weft knitting part is always in a stable state when working, thereby increasing the stability of the transmission device, thereby increasing the reliability of the weft knitting part when working, and ensuring that the knitted fabric woven has fewer defects.

[0004] When the above device is in use, when the prepared woven fabric is collected by a single collecting rod, the woven fabric has no external force support when it is just wound, resulting in less friction when the woven fabric is rolled up, making it easy for the entire rolling process to spread out and accumulate inside the machine body, and the woven fabric cannot be firmly wound on the collecting rod. If manual preliminary winding is performed, the woven fabric will come into contact with the staff's fingers, and the staff will be at great risk during the winding process, which may also easily cause hidden dangers to the staff's own safety.

The torque spring 851 is used to provide a rebound force to facilitate the resetting of the rotating plate 87.

[0038] During use, the weft knitting part 2 on the machine body 1 weaves the silk threads on the thread column 3 into cloth, which enters the interior of the machine body 1 under the action of the guide port 21, and then reaches the middle area of ​​the two semi-shaped rollers 51 in the process of the woven fabric falling continuously, and then the rotating motor 63 is started to drive the bidirectional screw rod 62 to rotate, and the semi-shaped roller 51 placed on the placement bin 65 is synchronously moved under the action of the bidirectional screw rod 62 and the threaded block 64. During the movement, the pushing rod 66 fixedly connected to the threaded block 64 will move toward the bidirectional screw rod 62, and the pushing rod 66 will contact the rotating plate 87 when it moves, so that the rotating plate 87 rotates under the extrusion of the pushing rod 66, and the sliding plate 86 The movable plate 81 is moved toward the semi-shaped roller 51. When the two semi-shaped rollers 51 are about to contact, the rotating clamping ring 82 arranged on the movable plate 81 clamps one end of the two semi-shaped rollers 51 on the inner cavity of the rotating clamping ring 82. Since the rotating clamping ring 82 is in a shape of an outer circle and an inner square, the rotating clamping ring 82 can rotate as it gradually approaches the semi-shaped roller 51, until one end of the two semi-shaped rollers 51 is finally completely clamped together, and one end of the two semi-shaped rollers 51 is locked at the same time. At the same time, under the action of the two semi-shaped rollers 51, the woven fabric can be clamped inside the two semi-shaped rollers 51 to form sufficient friction to prevent the woven fabric from falling off during the later stage of winding.
