Density triangular driving mechanism for computer flat knitting machine

Abstract

The invention relates to a density triangle drive mechanism of a flat knitting machine of computerized knitting, which belongs to the technical field of knitting machines. The invention comprises a motor, a cam, a clipping arm, a spring clipping plate and a second rolling wheel, the motor is arranged on a motor base, the motor base is fixed on a triangle bottom board, a motor shaft of the motor is drivingly interlocked with the cam, a rolling wheel groove is formed on one side of the cam, the upper surface of the clipping arm is provided with a first rolling wheel, and one end of the clipping arm is pivoted on a supporting stand, and a rolling wheel cavity is formed on the other end, a near middle part of the spring clipping plate is hinged with the clipping arm, and one end is interlocked with the clipping arm, and the other end contacts with the corresponded end of the clipping arm, a second rolling wheel is arranged on a density triangle guide block which is arranged on the rear surface of a density triangle and is embraced in the rolling wheel cavity. The invention is characterized in that the invention also comprises a blocking spring which is provided with a first spring arm and a second spring arm, the middle part of the blocking spring is located on the triangle bottom board through any locate mode of a direct locate mode and an indirect locate mode, and the first spring arm contacts with the density triangle guide block, and a second spring arm is fixed on the triangle bottom board. The invention has the advantages that motion deviation of the density can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to a density triangle driving mechanism of a computerized flat knitting machine. Background technique [0002] As the technical personnel in the field know well, a pair of triangular bottom plates (the industry is customarily called the front and rear triangular bottom plates) are fixedly installed on the head of the knitting mechanism of the computerized flat knitting machine, and each triangular bottom plate is movably provided with a For density triangles, the movement of each density triangle is realized by the work of the corresponding density triangle drive mechanism. When the knitting mechanism of the computerized flat knitting machine is in the state of knitting with yarn, the head reciprocates once every time it is left and right, and the density triangle moves up and down correspondingly. [0003] The specific structure of the density triangular dri...

Problems solved by technology

[0004] The shortcoming of the above-mentioned mechanism is: no matter from the perspective of the processing technology of the parts or the assembly angle of the parts, it is impossible to make the first roller 31 and the groove of the roller groove 22 The wall is maintained to a satisfactory degree of contact, that is to say, during the movement, there is a movement gap between the first roller 31 and the roller groove 22, which is specifically shown as: the position of the first roller 31 in the roller groove 22 exists Two kinds of uncertain sticking positions, that is, it is possible to stick to the upper groove wall of the roller groove 22, and it is also possible to stick to the lower groove wall of the roller groove 22, and the existence of the gap will cause the density triangle 6 to produce motion deviation, the gap The magnitude of the deviation is equal to the movement deviation of the density triangle 6, and the known deviation is 0.04-0.05mm. Although the deviation seems insignificant for a row of fabric, it is enough to accumulate to restrict the improvement of fabric grade.
