One-way boosting buffer mechanism for electronic jacquard opening mechanism

Abstract

The invention provides an unidirectional boosting cushioning mechanism of an electronic jacquard shedding mechanism, which belongs to the textile machinery electronic jacquard technical field and comprises a guiding screw which is installed between a compression spring upper seat and a compression spring lower seat and is arranged outwards from the middle and an outer compression spring, wherein the compression spring upper seat is hinged on the lower end of the symmetry bisector of a lifting rocking rod through a compression spring upper shaft, the compression spring lower seat is hinged on a wall panel through a compression spring lower shaft, and the axial cord of a live spindle of the lifting rocking rod, the axial cord of the compression spring upper shaft and the axial cord of the compression spring lower shaft are parallel to each other. The unidirectional boosting cushioning mechanism of an electronic jacquard shedding mechanism of the invention has the advantages that uneven load and impact noise are efficiently reduced during the operation of the electronic jacquard shedding mechanism, the dependability of the operation of the entire shedding mechanism is improved, and the mechanism has great efficiency of energy saving and labor saving, simple structure and convenient assembly.

Description

technical field [0001] The invention provides a one-way boosting and buffering mechanism in an electronic jacquard opening mechanism, which belongs to the technical field of electronic jacquard machines of textile machinery, and particularly relates to a mechanical opening mechanism of electronic jacquard machines with 1152 needles and above. Background technique [0002] At present, the electronic jacquard machines used in the textile industry all adopt the negative opening method, and the heald spring 4' is connected below, and the healds used to control the warp lifting are hung on the broach 2' through the vertical hook 3' (Fig. 1 ), the upward movement of the warp depends on the active pulling of the shedding mechanism, and at the same time it needs to overcome the resistance of the ever-increasing heald spring 4′, while the downward movement of the warp is completed by the elastic restoring force of the heald spring 4′, so the opening The whole process of movement is s...

Problems solved by technology

[0004] There was once a plan in the industry, that is, to place a spring opposite to the force direction of the heald spring on each broaching frame opposite to each other. The specific method is to set a compression spring under the broaching frame. This method is effective for upward broaching. Yes, but as the broach goes up and the spring compression decreases, its effect will gradually weaken; while the effect on the down broach is exactly the opposite of our expectation, the closer to the end of the opening, the greater the resistance, and its effect It is exactly the same as the spring return force of the upward broach, which generally increases the driving load and the impact after the high position, so it cannot effectively solve the problem of boosting and impact at the high position of the broach
