Description

Technical Field

[0001] The utility model relates to the field of lead mechanisms, in particular to a lead mechanism for a flat knitting machine. Background Art

[0002] With the progress of society, the textile industry has developed greatly, which puts forward higher requirements for textile production equipment. Textile production equipment also needs to be continuously improved to meet the needs of the new era. A flat knitting machine, namely a knitting flat machine, is one of the most common textile equipment.

[0003] Chinese Patent No. CN201921551947.6 discloses a lead mechanism for a flat knitting machine, which includes a machine body and a lead frame. The lead frame includes a frame body, a storage shell, a lead ring, a traction pipe, a lead-out pipe, a first air duct, a second air duct, a dust collector and a collection box. The frame body is connected to the machine body and the storage shell. The lead ring is placed in the storage shell and is movably connected to the storage shell. The traction pipe and the lead-out pipe are both connected to the storage shell and correspond to the lead ring. The first air duct is connected to the dust collector and the storage shell. The second air duct is connected to the dust collector and the collection box. The dust collector is placed on the machine body. The storage shell is provided with a first through hole and a second through hole that are respectively communicated with the traction pipe and the lead-out pipe. The storage shell is also provided with a third through hole that is communicated with the first air duct. The traction pipe is composed of a telescopic pipe body and a storage pipe body that are connected to each other. The telescopic pipe body is connected to the storage shell. The edge of the storage pipe body is bent inward to form a collection groove. The lead-out pipe is composed of a cotton cloth in a frustum shape.

[0004] As can be seen from the above, the yarn is pulled out from the yarn bobbin, passed through the lead frame and then input into the flat knitting machine for knitting. The yarn passes through the lead ring and rubs against the lead ring. The flying flocs generated by the friction between the yarn and the lead ring accumulate in the storage shell. The dust collector is started to suck out the flying flocs from the storage shell and discharge them into the collection box, so as to realize the collection of flying flocs at the source and complete the cleaning and collection. However, this case still has the following deficiencies: when guiding the yarn, the friction between the yarn passing through the lead ring and the lead ring will cause wear of the yarn, resulting in the quality of the subsequent use of the yarn not meeting the requirements. At the same time, the yarn is limited during the friction, and when the output position is inappropriate, the smooth wire feeding work cannot be carried out.

[0005] Therefore, a lead mechanism for a flat knitting machine is proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem that the quality of the subsequent use of the yarn cannot meet the requirements due to wear, the utility model proposes a lead mechanism for a flat knitting machine.

[0025] During operation, the limit cover 26 is rotated and removed from the fixed rod 24, the wire coil 27 is placed on the fixed rod 24, and then the wire coil 27 is fixed on the bearing plate 23 through the cooperation of the threaded screw 25 and the limit cover 26, ensuring that the wire coil 27 does not shake during the wire release operation.

[0026] Furthermore, a rotating shaft 21 is fixedly installed at the top of the fixed seat 1, a turntable 22 is movably installed at the top of the rotating shaft 21, and a bearing plate 23 is fixedly installed at the top of the turntable 22;

[0027] During operation, through the connection of the rotating shaft 21 to the turntable 22, when the wire coil 27 is performing the wire release operation, as the yarn is pulled, the bearing plate 23 will rotate on the rotating shaft 21 through the turntable 22. In this way, through the rotation adjustment of the bearing plate 23, it is beneficial to reduce the resistance suffered by the wire coil 27 during the wire release, making the wire release operation smoother.

[0028] Furthermore, two fixing posts 28 are fixedly installed at the top of the bearing plate 23, and fixing discs 29 are respectively fixedly installed on one side of the two fixing posts 28;

[0029] During operation, the bearing plate 23 supports and bears the fixing posts 28, ensuring the stability during the guidance of the wire release.

[0030] Furthermore, movable shafts 31 are respectively movably installed on the inner walls of the two fixing discs 29, and movable arms 32 are respectively fixedly installed at the other ends of the two movable shafts 31;
