Mechanism for adjusting density and tightness of knitted coil

Abstract

The invention relates to a mechanism for adjusting the density and the tightness of a knitted coil. The mechanism adopts the structure that a first end surface cam (2) is arranged on a first motor (1); a first bearing (3) is arranged on a shift lever (4), and is in rolling connection with the first end surface cam (2); one end of the shift lever (4) is hinged with a pivot (A); the other end of the shift lever (4) is connected with a density regulating triangle (5); a second end surface cam (10) is arranged on a second motor (11); a second bearing (9) is in rolling connection with the second end surface cam (10); one end of a supporting rod (8) is connected with the second bearing (9); the other end of the supporting rod (8) is connected with an eccentric connecting rod (7); the other end of the eccentric connecting rod (7) is connected with a T-shaped sliding block (6); one end of a V-shaped supporting rod (12) is connected with a sliding block (13) on the T-shaped sliding block (6); and the other end of the V-shaped supporting rod (12) is connected with a main density triangle (15) on the density regulating triangle (5). As a single-layered density triangle on a machine head is replaced by double-layered density triangles, the mechanism has the advantages that the vertical positions of knitting needles can be controlled; the regulating range is wide; the precision is high; and products such as sweaters, which are knitted according to the mechanism, have three-dimensional effects.

Description

Technical field [0001] The invention belongs to a component of a textile machine, and in particular relates to a knitting machine used on a knitting machine to adjust the tightness of the knitting loop density. Background technique [0002] At present, in the automatic computerized flat knitting machine, the adjustment of the degree of tightness of the sweater loop structure is realized by the difference in the depth of the needle presser foot by the head density triangle. Its control methods are mechanical or stepper motor control, etc., and its structure is different. At present, there are mainly two types of density adjustment structures commonly used in computerized flat knitting machines, one is an open cam density adjustment mechanism, and the other is a closed cam density adjustment mechanism. The open cam density adjustment mechanism is simple in structure, easy to adjust the part processing and density, but when the density triangle is pressed down by the shift lever, i...
