Density regulation device with drive cam for circular machine

Abstract

The invention discloses a density regulation device with a drive cam for a circular machine. The device comprises a drive mechanism, a transmission mechanism, a density triangular mechanism and a piston mechanism which are arranged on a triangular base, wherein the drive mechanism drives the density triangular mechanism to move through the transmission mechanism; the drive cam is composed of a base cam and a cam body which are fixedly connected; the base cam extends to be in an arc shape and provided with a protrusion with a sharp corner; and the cam body is arranged on the upper portion of the base cam and provided with a protruding edge which stretches outwards. During operation, the drive mechanism drives the drive cam on the drive mechanism to perform clockwise rotation together, and the drive cam abuts against a stop block arranged on a transmission block when rotating to a certain position, so that the transmission block and parts thereon are driven to move together. Due to special design structure and stop structure of the drive cam, the stability of the density regulation can be guaranteed effectively, and the failure rate of machines is reduced greatly.

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 driving cam. 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. At present, the structure of the drive cam used in the density adjustment device on the computer stockings machine is complicated, and special settings are required to achieve the purpose during the adjustment process. However, the drive cam is a key part in the density adjustment, and its structure and setting method will directly affect...

Problems solved by technology

At present, the structure of the drive cam used in the density adjustment device on the computer stockings machine is complicated, and special settings are required to achieve the purpose during the adjustment process. However, the drive cam is a key part in the density adjustment, and its structure and setting method will directly affect the density triangle mechanism. The up and down displacement of the fabric will also affect the size of the fabric coil and the quality of the density adjustment of the whole set of density adjustment devices.
