Problems solved by technology

[0003] There are many deficiencies in the design and use of the traditional triangular bottom plate, for example: 1) The density triangle has only a single-group structure, which can only realize single-group density control, and the density conversion range is small and cannot realize single-needle control
2). The combination of electromagnet and spring is used to control the switching of the triangle. Only the electromagnet energized iron core pops out to overcome the spring force to press the triangle down, and the electromagnet energized iron core retracts the spring to return the triangle to the initial position, which cannot meet the more complicated requirements. Patterns require more triangular positions
At the same time, when the electromagnet and spring work continuously for a long time, there are defects such as electromagnetic heating, electromagnetic failure and mechanical fatigue of the spring, which affect the working stability.
3). Triangular control cannot achieve closed loop. Once the electromagnet or spring does not work properly, the computer cannot immediately monitor and stop the alarm, and serious loss accidents will occur

Abstract

The invention relates to a dual-density triangular bottom plate for a horizontal knitting machine. Dual-density triangles, a dual-density control mechanism, a comprehensive control mechanism, a pressplate control mechanism and a push pin control mechanism are arranged on the triangular bottom plate. A function of controlling two groups of densities at the same time is achieved, and meanwhile, allthe control mechanisms are under closed-loop control by adopting stepping motors, so that the working reliability is improved, and a constant fault monitoring function is realized. The effects of high efficiency, low fault rate, modularization and multiple functions are achieved.

Description

technical field [0001] The invention relates to the technical field of flat knitting machines, in particular to a triangular bottom plate of a double density flat knitting machine. Background technique [0002] The triangular bottom plate is an important part of the computerized flat knitting machine. The function and stability of the triangular bottom plate directly determine the function and stability of the whole machine. In the design and use of the triangular bottom plate, it can complete the five basic functions of knitting, transferring, stitching, tucking and non-knitting. When the five functions are used alone or in combination, they need to rely on the transfer cam, knitting cam and pressing plate. Switching of components to achieve function switching requires the displacement of the density triangle to control the length of the coil, so as to realize various patterns and tightness of knitted products. [0003] There are many deficiencies in the design and use of ...
