Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machines, in particular to a high-speed double-sided knitting machine. Background Art

[0002] High-speed double-sided knitting machine is a professional equipment used to weave double-sided knitted fabrics. This machine can produce fabrics with double-sided structure at high speed. It is widely used in clothing, home textiles, automotive interiors and other fields.

[0003] For example, a computer numerical control double-sided knitting machine with publication number CN111088591B includes a first bracket, a cloth reel, a roll unloading vehicle, a base, and a second bracket. The top of the base is provided with a slope, and the roll unloading vehicle is provided inside the slope. The second bracket is installed at one end of the top of the base, and the first bracket is installed at the end of the top of the base away from the second bracket. Both the second bracket and the first bracket are provided with through holes, and bearings are installed on the inner sides of the through holes. The cloth roll can be wound by controlling the driving motor to start by cooperating with each other. At the same time, as the cloth roll is wound larger and larger, the fixed rod will drive the connecting rod and the first bracket to move outward. Since the second spring applies pressure to the first slider under its own elastic force, the roller can be tightly attached to the surface of the cloth roll, thereby improving the tightness of the cloth roll during winding and preventing the cloth roll from being loosened.

[0004] For example, a high-speed double-sided circular knitting machine with the publication number CN220952342U relates to the technical field of double-sided circular knitting machines, including a fixed frame, a weaving mechanism is installed on the inner wall of the fixed frame, a winding mechanism is rotatably installed below the weaving mechanism, and a ... By controlling the cylinder to contract, the push block and the two sliding blocks are driven to move upward along the inner wall of the corresponding sliding groove, and the two connecting blocks are driven to move together at the same time. While moving upward, the conveying box and the nozzle are slowly unfolded to both sides through the two rotating shafts so that the nozzle is aligned with the equipment, and then the driven wheel and the rotating table are driven to rotate by the motor, which in turn drives the conveying box and the nozzle to rotate around the equipment, solving the problem of long downtime, which causes the high temperature of the metal surface to come into contact with the air to produce a temperature difference, and the condensed water vapor condenses on the metal surface, causing the textile needles to rust, thereby slowing down the aging of the equipment;

[0005] The above-mentioned device drives the connecting rod and the bracket to move outward through the fixed rod, and drives the conveying box and the nozzle to rotate around the equipment, which can improve the tightness of the cloth roll when it is wound, prevent the cloth roll from loosening, and slow down the aging of the equipment. However, when using the device, the traditional coil transfer machine has a slow processing speed and low output. At the same time, it is easy to cause high-temperature overload and deformation at the high-speed operation position. During processing, the positioning mechanism is prone to shaking due to the operation of the device, and the shaking of the device is prone to offset, resulting in inaccurate positioning.
