A needle changing device for a rotary needle plate

Abstract

The invention provides a needle changing device of a rotation type needle board, and relates to the field of auxiliary equipment of textile manufacturing machines. The needle changing device is ingenious in structure, convenient to use and good in stability. The needle changing device comprises a working table, a sliding assembly and an action assembly. A hollow bearing platform is arranged in the middle of the working table and used for containing the needle board, and one side of the working table is provided with a lower slide opening in the length direction of the working table; the sliding assembly comprises a vertical column, a sliding plate and a hand wheel. The vertical column is vertically arranged on the top face of the working table, the top end of the vertical column is fixedly connected with an upper guide column, and the bottom end of the vertical column is fixedly connected with a lower guide column. The lower guide column is arranged in the lower slide opening in a penetrating mode, and the bottom end of the lower guide column is provided with a limiting plate which is attached to the bottom face of the working table. The sliding plate is arranged above the working table in parallel, an upper slide opening matched with the upper guide column is formed in the middle of the sliding plate, and the hand wheel is connected to the upper portion of the upper guide column in a threaded mode and pressed on the top face of the sliding plate. As a whole, the needle changing device has the advantages of being ingenious in structure, convenient to use and good in stability.

Description

technical field [0001] The present invention relates to the field of textile machinery auxiliary equipment, and in particular to the improvement of the device for changing the needles of the needle board therein. Background technique [0002] Such as Figure 1-2 As shown, the needle plate is one of the commonly used parts in textile machinery. Due to the influence of the use time and strength, the needles on the needle plate often need to be replaced. In the prior art, tools such as hammers are usually used to manually replace the needles, especially the removal process of the needles is extremely inconvenient, time-consuming, laborious and dangerous. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a rotary needle plate needle changing device that is compact in structure, easy to use and good in stability, and can effectively avoid direct contact of operators, thereby improving work efficiency and reducing labor intensity. ...
