[0029] Among them, the docking shaft 335 and the compression spring 336 are symmetrically arranged laterally along both sides of the connecting strip 334, and the right side of the compression spring 336 is against the movable frame 337, ensuring the efficient combination of the docking shaft 335 and the compression spring 336, realizing the extrusion push and elastic pullback transmission of the movable frame 337; the movable frame 337 is arranged in a T-shaped frame as a whole, and the middle of the right side of the movable frame 337 passes through the right side of the box body 331, so that the movable frame 337 can realize smooth outward movement or pullback coordination, ensuring flexible adjustment of the overall tightness of the smearing component 34.

[0030] See also Figure 5 The smearing assembly 34 in this embodiment includes a connecting shell 341 that is docked to the right side of the movable frame 337 for connection, a brush cylinder 342 that is movably built into the connecting shell 341 and can realize the brushing and smearing of the lubricating liquid, a docking tube 343 that is vertically inserted into the connecting shell 341 and the brush cylinder 342 for rotational connection, and the upper end of the docking tube 343 is connected to the oil outlet end of the oil filling pipe 35, and pressure blocks 344 are symmetrically arranged at the upper and lower ends of the connecting shell 341 to realize fast connection and cooperation, and oil outlets 345 are symmetrically opened on both sides of the outer end of the docking tube 343.

[0032] Here’s how it works:

[0033] When the needle cylinder of the knitting machine is to be used, the needle cylinder body 1 can be connected to the inside of the docking ring 31 during installation. At the same time, the docking ring 31 is connected to the installation part of the knitting machine to achieve the rotational docking activity of the needle cylinder body 1 and the docking ring 31. In this way, a rotational guide function can be provided when the needle cylinder body 1 performs a rotational weaving activity.

[0034] However, when the syringe body 1 is stuck in rotation, the screw 332 that is rotated and connected to the middle part of the left side of the box body 331 can be rotated to make the screw 332 and the connecting tube 333 that is threadedly connected to the outside be threadedly driven, so that the connecting strip 334 that is connected to the outside of the connecting tube 333 can be moved to the right. As the connecting strip 334 moves to the right, the docking shafts 335 and compression springs 336 that are connected to both sides of the connecting strip 334 will cooperate at the same time to push the moving frame 337 as a whole, so that the moving frame 337 pushes the connecting shell 341 inside the smear component 34 to the right, thereby making the brush barrel 342 installed inside the connecting shell 341 abut against the outer side of the lower end of the syringe body 1. , to prepare for smearing, at the same time, the external lubricating liquid will be injected through the oil filling pipe 35 connected to the upper end of the docking tube 343, so that the lubricating liquid entering the docking tube 343 will enter the brush cylinder 342 from the oil outlets 345 opened on the left and right sides of the docking tube 343, so that the brush cylinder 342 is soaked as a whole, and then, when the syringe body 1 rotates along the inside of the docking ring 31, the soaked brush cylinder 342 can brush and smear the lubricating liquid on the outer side of the lower end of the syringe body 1, thereby realizing the self-lubricating brushing activity of the syringe body 1, ensuring the flow of the rotation process of the syringe body 1, and avoiding the occurrence of problems such as rotation jamming and rotation wear;

[0035] Under the threaded transmission of the screw rod 332 and the connecting tube 333, the movable frame 337 can be subjected to the combination of the docking shaft 335 and the compression spring 336 to flexibly adjust the extrusion tightness of the brush cylinder 342 and the outer side of the lower end of the syringe body 1, so that the lubricating liquid can be applied and extruded in large quantities or in small quantities. Flexible adjustment can be achieved according to lubrication requirements to avoid excessive application and waste of lubricating liquid. At the same time, the excess extruded lubricating liquid can flow into the recovery tank 32 opened at the lower end of the interior through the recess opened on the left side of the docking ring 31, so as to realize the recovery and reuse of the excess lubricating liquid, ensure the use of the lubricating liquid, and avoid the occurrence of waste problems.
