Abstract
The utility model relates to the field of knitting devices. A yarn conveyor comprises a shell body, a transmission belt wheel, a clutch, a yarn conveyance wheel and a main shaft, wherein the transmission belt wheel, the clutch, the yarn conveyance wheel and the main shaft are arranged on the shell body, the main shaft penetrates through the shell body up and down, the upper part of the main shaft is connected with the transmission belt wheel and the clutch, and the lower part of the main shaft is connected with the yarn conveyance wheel; and the yarn conveyance wheel comprises a yarn conveyance wheel upper seat, a yarn guide steel wire and a yarn conveyance wheel lower seat, and a hard chrome layer is plated on the surface of the yarn guide steel wire. The yarn conveyor disclosed by the utility model has the advantages of novel structure, good durability in the yarn conveyance wheel, and long service life.
Description
Technical field
The utility model relates to the knitting equipment field, especially a kind of yarn-feeding device.
Background technology
Yarn-feeding device is one of critical piece on the knitting machine, and existing knitting yarn-feeding device generally comprises housing, drive pulley, clutch and line-transmitting wheel, and main shaft runs through housing up and down, and its top links to each other with drive pulley, clutch, and the bottom links to each other with line-transmitting wheel.During work; The drive pulley that transmission band on the knitting machine drives yarn-feeding device top rotates; Turn to line-transmitting wheel through clutch, main shaft; Make line-transmitting wheel produce rotation, thereby pull out the yarn on the yarn tube, the below through lead frame, thread nipper assembly, knot filter, preceding feeler, be wrapped on the circumferential surface of line-transmitting wheel after advancing yarn porcelain circle; Yarn on the line-transmitting wheel carries out operation through the knitting needle on the below supply knitting machine of yarn porcelain circle, back feeler simultaneously, and line-transmitting wheel plays the function that stores yarn and delivered yarn.Line-transmitting wheel is made up of following of the line-transmitting wheel seat of honour, guide steel wire and line-transmitting wheel.Because the guide steel wire is the stainless steel wire brake forming, consistent for the dimensionally stable that guarantees line-transmitting wheel, the hardness of guide steel wire is all below HV450.And for some yarn, chemical-fibres filaments for example, yarn-feeding device is after use after a while; The guide steel wire of line-transmitting wheel will wear and tear; The conveying that hinders yarn makes yarn-feeding device send yarn unstable, and serious also can cause yarn breakage, makes the range of application of yarn-feeding device obtain restriction like this.
Summary of the invention
The goal of the invention of the utility model is in order to overcome the deficiency that above-mentioned existing yarn-feeding device exists, a kind of novel structure to be provided, the yarn-feeding device that the line-transmitting wheel ABRASION RESISTANCE is good.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of yarn-feeding device, comprise housing and on drive pulley, clutch, line-transmitting wheel and main shaft, main shaft runs through housing up and down, main shaft top links to each other with clutch with drive pulley, the main shaft bottom links to each other with line-transmitting wheel; Said line-transmitting wheel comprises following of the line-transmitting wheel seat of honour, guide steel wire and line-transmitting wheel, and the surface of said guide steel wire is coated with hard chrome coating.
As preferably, said yarn-feeding device also comprises the lead frame, thread nipper assembly, knot filter, the preceding feeler that are located on the housing, advances yarn porcelain circle, yarn porcelain circle and back feeler.
Adopted a kind of yarn-feeding device of technique scheme, the surface of guide steel wire is coated with hard chrome coating, and hardness can be increased to more than the HV700 by original≤HV450, and the anti-wear performance of line-transmitting wheel improves greatly, longer service life.The advantage of this yarn-feeding device is a novel structure, and the line-transmitting wheel ABRASION RESISTANCE is good, long service life.

Fig. 2: the structural representation of line-transmitting wheel among the utility model embodiment
The specific embodiment
The utility model is done with Fig. 2 below in conjunction with accompanying drawing 1 and to be further described.
A kind of yarn-feeding device as depicted in figs. 1 and 2, comprise housing 1 and on drive pulley 2, clutch 3, line-transmitting wheel 4, main shaft, lead frame 5, thread nipper assembly 7, knot filter 6, preceding feeler 8, advance yarn porcelain circle 9, yarn porcelain circle 11 and back feeler 10.
Main shaft runs through housing 1 up and down, and main shaft top links to each other with clutch 3 with drive pulley 2, and the main shaft bottom links to each other with line-transmitting wheel 4.Line-transmitting wheel 4 comprises following 43 of the line-transmitting wheel seat of honour 41, guide steel wire 42 and line-transmitting wheel, and the surface of guide steel wire 42 is coated with hard chrome coating, and hardness can be increased to more than the HV700 by original≤HV450, and the anti-wear performance of line-transmitting wheel 4 improves greatly.
During use; The drive pulley 2 that transmission band on the knitting machine drives yarn-feeding device top rotates; Turn to line-transmitting wheel 4 through clutch 3, main shaft; Make line-transmitting wheel 4 produce rotation, thereby pull out the yarn on the yarn tube 12, the below through lead frame 5, thread nipper assembly 7, knot filter 8, preceding feeler 8, be wrapped on the circumferential surface of line-transmitting wheel 4 after advancing yarn porcelain circle 9; Yarn on the line-transmitting wheel 4 carries out operation through the knitting needle on the below supply knitting machine of yarn porcelain circle 11, back feeler 10 simultaneously, 4 functions that store yarn and delivered yarn of line-transmitting wheel.
Claims (2)
1. yarn-feeding device, it is characterized in that comprising housing and on drive pulley, clutch, line-transmitting wheel and main shaft, main shaft runs through housing up and down, main shaft top links to each other with clutch with drive pulley, the main shaft bottom links to each other with line-transmitting wheel; Said line-transmitting wheel comprises following of the line-transmitting wheel seat of honour, guide steel wire and line-transmitting wheel, and the surface of said guide steel wire is coated with hard chrome coating.
2. a kind of yarn-feeding device according to claim 1 is characterized in that also comprising the lead frame, thread nipper assembly, knot filter, the preceding feeler that are located on the housing, advances yarn porcelain circle, yarn porcelain circle and back feeler.
