Different fabrics require different densities during knitting, so the knitting density needs to be accurately adjusted. The traditional knitting density adjustment of the flat knitting machine is mainly realized by controlling the density cam. The operator needs to directly push the density cam screw upper end for adjustment, which not only requires a large operating force, but also the operating point is not ideal in mechanics due to the need to overcome the tension of the tension spring, which causes the density cam to be easily stuck and not pushed.

[0025] When the knitting density needs to be adjusted, the two synchronous motors 4 are started in this embodiment. The synchronous motors 4 are operated to drive the worm gears 5 connected thereto to rotate. Since the worm gears 5 are externally meshed with the worm wheels 9, the rotation of the worm gears 5 drives the worm wheels 9 to rotate. When the worm wheels 9 rotate, the half-threaded columns 7 fixedly connected thereto rotate. Since the bottom ends of the half-threaded columns 7 are rotatably connected with the connecting blocks 8, the half-threaded columns 7 can rotate around their own axes.

By changing the positions of the triangular dense blocks 12, the spacing parameters of the needle beds during the knitting process can be adjusted, so as to realize accurate adjustment of the knitting density.

[0026] Embodiment Two

[0029] The working principle and use process of the utility model are as follows: start two synchronous motors 4, the synchronous motor 4 runs and drives the worm 5 connected with it to rotate, the rotation of the worm 5 drives the worm wheel 9 to rotate, the rotation of the worm wheel 9 drives the half screw column 7 fixedly connected with it to rotate, so that the half screw column 7 can rotate around its axis, and the half screw column 7 bottom end is externally threadedly connected with the sliding block 10, in the rotation process of the half screw column 7, the sliding block 10 moves along the axial direction of the half screw column 7, the movement of the sliding block 10 drives the connecting rod 11 to move, the guide slot 13 provides accurate guidance for the movement of the connecting rod 11, and ensures that the connecting rod 11 can only move in the predetermined direction; with the sliding of the limiting block 15, the spring 17 outside the damping rod 18 is compressed or stretched. The elastic force of the spring 17 acts on the limiting block 15 through the damping rod 18, effectively slows down the movement speed of the connecting rod 11, the buffer plate 16 further absorbs the kinetic energy of the connecting rod 11 through the deformation of the buffer plate 16 and the friction between the buffer plate 16 and the connecting rod 11, so that the connecting rod 11 gradually stops moving, thereby realizing accurate limiting and buffering of the connecting rod 11 and guaranteeing the stability and reliability of the whole device in the running process.
