Three-dimensional spherical surface knitting machine capable of eliminating radial clearance and reducing abrasion of spindle rail

Abstract

The invention relates to a three-dimensional spherical surface knitting machine capable of eliminating radial clearance and reducing abrasion of a spindle rail, which comprises a knitting machine head assembly and a support frame, the knitting machine head assembly is arranged on the support frame, and the three-dimensional spherical surface knitting machine is characterized in that the knitting machine head assembly comprises a machine head body, an embedded block, a driving plate transmission device, a spindle component and a knitting ring component. The track grooves in the embedded blocks are twisted curved surfaces, so that smooth transition transmission of the guide blocks between the track grooves can be ensured; in the three-dimensional weaving process, a radial gap can be generated when a spindle is transmitted between driving plates, so that the transmission process is unstable, a belleville spring is used at the joint of the lower part of the spindle and the upper part of the spindle in a spindle assembly, and the radial gap generated when the spindle is transmitted between the driving plates can be eliminated; the guide blocks are installed through spherical hinges, and it is guaranteed that the guide blocks are attached to the rail grooves all the time when sliding in the rail grooves.

Description

technical field [0001] The invention relates to a three-dimensional spherical braiding machine. Background technique [0002] At present, there are two main types of knitting machines on the market: vertical knitting machines and horizontal knitting machines. The disadvantages of the existing knitting machine transmission structure are: the movement mode is suitable for two-dimensional plane motion weaving, but it is difficult to meet the requirements for three-dimensional weaving. During the three-dimensional weaving process, the spindle will have radial clearance with the dial and the guide block will not fit with the track groove, which will cause the weaving process to be stuck, which makes the weaving process very unstable. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is that the existing braiding machine vibrates greatly and is unstable during the three-dimensional braiding process. [0004] In order to solve the abo...

Problems solved by technology

The shortcomings of the existing knitting machine transmission structure are: its motion mode is suitable for two-dimensional plane knitting, but it is difficult to meet the requirements for three-dimensional knitting

In the process of three-dimensional weaving, the radial gap between the spindle and the dial will be generated when the spindle moves, and the guide block will not fit the track groove, which will cause the weaving process to be stuck, making the weaving process very unstable
