Jacquard pulley mechanism

Abstract

The invention relates to a jacquard pulley mechanism. The jacquard pulley mechanism comprises an upper cover plate, a lower cover plate, a support and rollers, wherein the upper cover plate is matched with the lower cover plate, and the rollers are positioned between the lower cover plate and the support. Compared with the prior art, the jacquard pulley mechanism has the following advantages and effects that a large amount of space can be saved, more pulley mechanisms can be arranged in the same size, and more heddles can also be arranged, so that the wire number of a jacquard can be increased, and the economical benefit is increased; the whole pulley mechanism comprises four components, so that the integration degree is very high; the components are reduced, so that the space is saved, and the rollers of the large diameter can be selected; the rollers of the large diameter have the advantages that the rolling effect is good, stronger loads can be born, and a high-speed effect can be fitted.

Description

technical field [0001] The invention relates to a pulley mechanism of a jacquard machine, belonging to parts of textile machinery. Background technique [0002] Jacquard machine is a kind of textile machinery. Existing jacquard machines generally use metal pulleys installed on a metal shaft. Due to the complex structure of the metal pulley itself, there are inner sliding sleeves, balls and outer sliding sleeves. When the balls are worn, the balls will can slip out between the inner and outer sleeves, reducing the durability of the metal pulley. The metal shaft itself needs to take up space, plus the inner sliding sleeve and the outer sliding sleeve, the space required is very huge. In the jacquard process, because the healds are very dense on the jacquard machine, the large-space bearing and pulley structure will greatly reduce the number of healds, thereby reducing the overall performance of the jacquard machine. In addition, the use of metal inner sliding sleeves, balls,...

[0002] Jacquard machine is a kind of textile machinery. Existing jacquard machines generally use metal pulleys installed on a metal shaft. Due to the complex structure of the metal pulley itself, there are inner sliding sleeves, balls and outer sliding sleeves. When the balls are worn, the balls will Can slip out between inner and outer sleeves, reducing durability of metal pulleys

The metal shaft itself needs to take up space, plus the inner sliding sleeve and outer sliding sleeve, the space required is very huge

In the jacquard process, the heddles on the jacquard machine are very dense, so the large-space bearing and pulley structure will greatly reduce the number of healds, thereby reducing the overall performance of the jacquard machine.

In addition, the use of metal inner sliding sleeves, balls, and outer sliding sleeves will cause strong wear between the balls and the inner sliding sleeves, and between the balls and the outer sliding sleeves. Therefore, it is necessary to add lubricating substances. Lubricating substances is a very large job, so its maintenance performance is poor
