Description

Reverse-suction combined needle selection structure and needle selection module of jacquard

Technical Field

The utility model relates to the technical field of jacquard machines, in particular to a reverse-suction combined needle selecting structure and a needle selecting module of a jacquard machine.

Background

The size of the needle selection module of the jacquard determines the number and the size of the needles of the jacquard. At present, as in the chinese utility model patent 2020214389961, the needle selection module is generally a movable iron which is arranged on both sides of the electromagnet through the electromagnet, the vertical hook and the movable iron, the movable iron is matched with the vertical hook, and in the vertical hook up-and-down motion process, the electromagnet generates magnetic force according to the requirement, and the movable iron is attracted. At present, a common needle selection structure utilizes an electromagnet to attract a movable iron, so that the movable iron is not interfered with a vertical hook, and when jacquard is needed, the electromagnet is powered off, and the vertical hook is hung by the movable iron. However, in the actual weaving process of the jacquard fabric, the jacquard fabric only occupies a small amount of position and time, so that the electromagnet needs to be electrified to attract the movable iron most of the time. This results in a high energy consumption of the needle selection module.

SUMMERY OF THE UTILITY MODEL

The utility model provides a reverse-suction combined needle selecting structure and a needle selecting module of a jacquard machine, aiming at solving the technical defects, and the structure and the module have small overall size and low energy consumption.

The utility model discloses a reverse-suction needle selection structure of a jacquard, which comprises an electromagnet and a vertical hook, wherein elastic steel sheets are vertically arranged on two sides of the electromagnet, a notch for hanging the vertical hook is arranged at the lower end of each steel sheet, an iron core at the lower end of the electromagnet is positioned above the notch of the steel sheet, a gap is formed between each steel sheet and the end part of the iron core at the lower end of the electromagnet, the vertical hook is positioned between the two steel sheets in the vertical direction, the hook part of the vertical hook faces towards the steel sheets on the same side, and when the electromagnet sucks the steel sheets, the hook part of the vertical hook is matched and connected with the notch of the steel sheets.

Above-mentioned technical scheme, in the in-service use, set up elastic steel sheet on the electro-magnet, and the connection position of steel sheet is located the iron core top of electro-magnet actuation steel sheet, because the carabiner sets up between two steel sheets, under the natural state, under the circumstances of electro-magnet outage promptly, the steel sheet is in vertical state, does not interfere between carabiner and the steel sheet, so under the circumstances that does not jacquard, the electro-magnet all is in the circumstances of outage, and when needs carry the flower, the electro-magnet circular telegram carries out the actuation with the steel sheet for the steel sheet is close to the carabiner side, makes its hook portion of carabiner lift in-process and the breach of steel sheet cooperate, hooks the carabiner, makes it unable decline, thereby realize the jacquard weave. Therefore, in the process of weaving the fabric, the electrifying time of the electromagnet is relatively short, and the energy consumption is low. In addition, due to the design of the steel sheets on the two sides of the electromagnet, the number of parts is greatly reduced, the overall size of the needle selecting structure is reduced, and the assembling cost is lower. Wherein the steel sheet and the electromagnet can be molded into an integral structure.

The two end faces of the iron core below the electromagnet are both of inclined surface structures, and when the electromagnet attracts the steel sheet, the two end faces of the iron core below the electromagnet are completely attached to the inclined steel sheet. The design of this structure, when the electro-magnet with the steel sheet actuation, the area of contact of the iron core of electro-magnet and steel sheet is big, the stability of actuation is high.

The needle selecting module comprises a bottom plate, a plurality of clamping plates and a cover plate, wherein needle selecting mechanisms are arranged between the bottom plate and the clamping plates, between adjacent clamping plates and between the clamping plates and the cover plate, each needle selecting mechanism comprises an electromagnet, two steel sheets, two vertical hooks, a first threading wire connected between the two vertical hooks, a second threading wire and a pulley block, and a quick connector is arranged on the second threading wire. The whole size of the structure is greatly reduced, parts are greatly reduced, the assembly process can be simplified, and the cost is reduced.

According to the back-suction needle selecting structure and the needle selecting module of the jacquard, the number of accessories of the needle selecting module can be effectively reduced through the position design of the steel sheet and the vertical hook, the overall size can be reduced, the cost is reduced, and meanwhile, the electromagnet is electrified only during jacquard, so that the energy consumption is lower.
