Problems solved by technology

[0006] The existing three-dimensional knitting circular knitting machine based on the four-step method is composed of three-dimensional knitting flat knitting machines, and the movement of the yarn carrier between the knitting machines is completed by manual operation, which has high labor costs, low production efficiency, and high error probability.
Moreover, the chassis drive of the existing three-dimensional flat knitting machine has the following disadvantages: (1) the structure is complex; (2) the processing cost is high; (3) the braid structure is single
However, the four driving mechanisms of this device cooperate with the horizontal and vertical movements of the odd and even rows, which are not suitable for three-dimensional circular knitting machines, and the driving mechanisms are still relatively complicated.

[0051] like image 3 As shown, this embodiment is a further limitation of Embodiment 1. The cylinder driving mechanism includes a circumferential driving cylinder 15, and the two sides of the driving square tube 6 are respectively provided with a circumferential driving cylinder 15, and the piston of the circumferential driving cylinder The rods are movably connected with the driving square tubes 6 respectively, and drive the driving square tubes and corresponding circumferential guide rails to perform circumferential reciprocating motion within a certain angle.

[0052] The circumferential driving cylinder is arranged on both sides of the driving square tube, and drives the driving square tube to perform circumferential reciprocating motion within a certain angle, so as to realize the conversion of the linear motion of the piston rod of the circumferential driving cylinder into the circumferential motion of the driving square tube. The circumferential driving cylinder can be ...

Embodiment 3

[0060] like Figure 4 As shown, the present embodiment is a further limitation of Embodiment 2. The cylinder driving mechanism 7 also includes a square pipe groove 17 for limiting the rotation angle of the driving square pipe, and the driving square pipe 6 passes through the square pipe groove 17. Driven by the rod 6, between the two ends of the square pipe groove 17, it rotates around the central axis of rotation.

[0061] According to the needs of the braided structure, the rotation angle of the driving square tube can be limited. When the driving square tube moves to the two ends of the square tube groove, the motion stops and the movement in the opposite direction is ready.

[0062] Further, the square pipe groove 17 is installed on the support frame 14, and the two ends of the square pipe groove are provided with limit screw rods 18, and the limit screw rods are sleeved with limit nuts 19 to limit the length of the square pipe groove.

[0063] By rotating the limit nut a...

Description

technical field [0001] The invention belongs to the technical field of three-dimensional knitting, and relates to a chassis driving device of a three-dimensional knitting machine, in particular to a chassis driving device of a three-dimensional knitting circular machine based on a four-step method. Background technique [0002] Three-dimensional weaving has a history of nearly 30 years in foreign countries, and has experienced more than 20 years of development since it was introduced into China, and has made great progress. The "four-step method" three-dimensional weaving technology enables textile reinforced structural composite materials to develop from single fiber reinforcement, yarn reinforcement, and two-dimensional fabric reinforcement to three-dimensional profiling reinforcement. The composite material with prefabricated parts formed by this weaving process as a reinforced structure can avoid the delamination phenomenon of traditional laminated structure composite ma...
