Embodiment Construction

[0030] See attached picture. This embodiment is composed of a driving mechanism, a transmission mechanism, a dynamic density transmission mechanism and a piston mechanism. The driving mechanism is transmitted to the transmission mechanism, thereby driving the dynamic density transmission mechanism connected with the transmission mechanism to move, thereby completing the program instructions. The transmission mechanism includes a triangular base 7 with a transverse installation hole on the triangular base 7 , a transmission rod 21 in the installation hole, and a density cam 28 fixedly installed at one end of the transmission rod 21 .

[0031] The dynamic density transmission mechanism includes a dynamic density triangle base 1 , a dynamic density triangle slider 2 , a dynamic density needle pressing cam 3 , and a dynamic density needle lifting cam 4 . The dynamic density pressing cam 3 includes a needle trajectory surface 31, which is formed by connecting the first needle traj...

Abstract

The invention discloses a circular knitting machine density adjusting device with a density cam mechanism, which comprises a driving mechanism, a transmission mechanism, a dynamic density triangular mechanism and a piston mechanism, wherein the driving mechanism, the transmission mechanism, the dynamic density triangular mechanism and the piston mechanism are all arranged on a triangular base, and the driving mechanism drives the dynamic density triangular mechanism to move through the transmission mechanism; the density cam mechanism is composed of a density cam and a transmission rod, and the density cam is fixedly connected to one end of the transmission rod; and the density cam is arranged in a groove of a dynamic density triangular sliding block. When a density motor works, the transmission rod transmits the rotation to the density cam, and the density cam can press down the dynamic density triangular sliding block through rotating in the groove of the dynamic density triangular sliding block. Through the density cam mechanism with the structure, sensitive action and stable performance can be achieved in the adjusting process, so that the weaving quality of the fabric is ensured, and the stability of a machine is improved.

Description

technical field [0001] The invention relates to the technical field of knitting machines, in particular to a circular knitting machine density adjusting device with a density cam mechanism. Background technique [0002] In knitting machines, in order to adjust the density of the formed fabric, it is often necessary to use a density adjustment device. In the flat knitting machine, there is a relatively mature density adjustment device, which generally includes a density motor to drive the movement of the density cam slider. The density cam slider is equipped with a density pressing cam and a density lifting cam. control to change the fabric density. The density cam used on the current density adjustment device is not only complex in structure, but also prone to slipping due to improper setting during the adjustment process, resulting in poor fabric quality. Contents of the invention [0003] In order to solve the above problems, the present invention provides a circular ...
