Description
Technical field
The present invention relates to the accessories field of loom.
Background technology
The important accessory of yarn-feeding device loom, it includes housing and the drive pulley being arranged on housing, clutch, master
Axis, line-transmitting wheel, dustproof cover, lead frame, it is preceding detection bar, into yarn porcelain circle, yarn gripper, yarn porcelain circle and after detect bar；Drive pulley
The top of housing is arranged on clutch, line-transmitting wheel is arranged on the lower section of housing, dustproof cover, main shaft top are housed above line-transmitting wheel
It is connected with drive pulley, clutch, main shaft lower part is connected with defeated yarn wheel, and lead frame, set into yarn porcelain circle, yarn gripper and yarn porcelain circle
Put on housing.During work, the transmission band on knitting machine drives the drive pulley on knitting yarn transport device top to rotate,
Through clutch, main axis to defeated yarn wheel, defeated yarn wheel is produced rotation, so that the yarn on tube is pulled out, by lead frame,
Preceding detection and is wrapped on defeated yarn wheel bar into yarn porcelain circle, at the same the yarn on defeated yarn wheel by yarn gripper, yarn porcelain circle and after visit
Knitting needle on measuring staff supply knitting machine carries out operation, and defeated yarn wheel plays the function of storage yarn and delivered yarn.
Including for defeated yarn wheel is following several, and a kind of is plastic casing, and metallic rod or pottery are installed on the defeated yarn face of housing
Porcelain bar is used for delivered yarn, and shortcoming is that plastic casing service life is short, and the metallic rod or ceramic bar filled afterwards not only answer by structure
Miscellaneous, dimensional accuracy is low, and in addition for plastic casing due to injection molding, mismachining tolerance is big, causes defeated yarn wheel assembling post-processing error big；
Another is currently on the market using relatively more extensive, defeated yarn wheel generally metal shell, surface hard oxidation or surface spray
Hard Chromium Coating or spray ceramic layer are applied, the benefit of surface hard oxidation is bonding strength height, the surface ruler of superficial layer and metal shell
Very little precision is high, its deficiency is that case hardness is low；The benefit of surface spraying Hard Chromium Coating is surface size precision height, its deficiency is table
Surface layer is low with the bonding strength of metal shell, case hardness is low；The benefit of surface spray ceramic layer is case hardness height, and deficiency is pottery
Enamel coating bonding strength is low, surface size precision is low.Existing defeated yarn wheel common problem is using a period of time rear yarn wadding etc.
Debris can be accumulated between defeated yarn wheel and dustproof cover, rotate defeated yarn wheel dumb, so as to cause to drive on its rotating drive
Transmission belt stress increase, make transmission belt unstable wear, serious or even transmission belt cannot drive drive to rotate, and with transmission
Slipping phenomenon is produced between wheel, prevents Thread-feeding device from delivered yarn.In order not to influence the normal rotation of defeated yarn wheel, it is necessary to periodically clear
It is to need to dismantle yarn-feeding device to manage debris, the current manner of cleaning up such as the yarn wadding in defeated yarn wheel, and defeated yarn wheel is removed from main shaft
Cleared up, it is time-consuming and laborious.
The content of the invention
