摘要:
A sinker control apparatus (30) for flat knitting machines located on a transverse board (12) over a plurality of knitting needles (21) to drive parallel sinkers (22) hinged between the knitting needles (21) to rotate. The sinker control apparatus (30) includes a base (31), a linked movement portion (32) located on the base (31) to perform driving movements, a first control cam (33) and a second control cam (34) hinged on the linked movement portion (32), and a switching portion (35) coupled with the linked movement portion (32). The switching portion (32) includes at least one connection rod (351) connecting to the linked movement portion (32), a switching seat (352) coupled on the connection rod (351) and an elastic element (40) coupled around the connection rod (351) to provide a butting force to the switching seat (352) towards the transverse board (12). The switching seat (352) has a magnetic attracting portion (50) at one side facing the transverse board (12) to attract the transverse board (12) magnetically.
摘要:
A yarn feeder for flat knitting machines is located on a yarn feeder guide track (10) to move transversely thereon and includes a baseboard (21) slidably coupled on the yarn feeder guide track (10), a first rocking arm (22), a second rocking arm (23) and a yarn feeding unit (24) located on the baseboard (21). The first and second rocking arms (22, 23) have respectively a first pivot end (221) and a second pivot end (231) coupled with the baseboard (21), and a first pressed end (222) and a second pressed end (232) to receive a horizontal force to swing respectively about the first and second pivot ends (221, 231) serving as fulcrums. The yarn feeding unit (24) includes a yarn feeding arm (25) located between the first and second rocking arms (22, 23), and a first linkage bar (241) hinged on the yarn feeding arm (25) and first rocking arm (22) to move simultaneously, and a second linkage bar (242) hinged on the yarn feeding arm (25) and second rocking arm (23) to move simultaneously.
摘要:
A downward pressing mesh mechanism and sinker thereof for flat knitting machines in which the downward pressing mesh mechanism includes a needle seat (10) containing a bearing surface (11) to hold a plurality of sinkers (7) and knitting needles (8) separated by spacers (3) and a cam holder (2) localed above the sinkers (7) to hold a cam (20). The cam (20) has a guide track (21) to drive the sinkers (7) swinging. The spacers (3) are vertically run through by a bracing shaft (4) at a lower side. Each sinker (7) includes a yarn pressing portion (75) to press a yarn to form a mesh, a swing guide portion (70) driven by the guide track (21) and a shaft rotating recess (73) to couple with the bracing shaft (4). The sinker (7) thus structured is simpler and durable, hence can be produced and assembled. or repaired and replaced easier and faster. Thus manpower and material costs can be reduced, and product prices also are decreased to meet market requirements.
