Guide yarn base convenient to change guide needle

Abstract

The invention relates to a guide yarn base convenient to change guide needles. A connection plate is provided with sliding chutes. A set block can be slidably arranged in the sliding chutes through a sliding block on the bottom end. The set block is connected with a mobile cylinder on one side of the connection plate. The set block is internally provided with a mounting groove. The upper end of the mounting groove is provided with a cover plate which is connected with the set block. The bottom of the mounting groove is provided with two elevating cylinders. The upper ends of the expansion rods of the elevating cylinders are connected with a first positioning plate. The upper end of the first positioning plate is provided with a second positioning plate. The second positioning plate is provided with a guide needle. The guide needle passes through the cover plate and is exposed out of the cover plate. Springs are arranged between the second positioning plate and the cover plate. The second positioning plate and the cover plate are respectively detachably connected with the springs. The guide yarn base convenient to change guide needles is simple in structure and labor-saving in operation, and can laterally move the guide needle and adjusts height of the guide needle, so as to optimize the position of the guide needle according to actual conditions. The guide yarn base is good in use flexibility, and changing of the guide needle is convenient, the guide yarn base is low in production cost, and preferably satisfies actual use requirements.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a yarn guide seat which is convenient for replacing yarn guide needles. Background technique [0002] In the spinning process, in order to ensure the smooth running of the yarn and avoid the occurrence of mutual interference and disordered arrangement of the yarn, the yarn is usually carded, guided and positioned by the yarn guide device at present. The current yarn guide seat includes a yarn guide needle and a positioning plate. The yarn guide needle is fixed on the positioning plate, and then the positioning plate is installed on the textile equipment. However, after a long period of use, it is found that such a structure has some shortcomings. The position of the yarn needle cannot be flexibly adjusted according to the actual use needs, and the flexibility of use is poor. At the same time, when the yarn guide needle is damaged, the entire yarn guide seat ...

The current yarn guide seat includes a yarn guide needle and a positioning plate. The yarn guide needle is fixed on the positioning plate, and then the positioning plate is installed on the textile equipment. However, after a long period of use, it is found that such a structure has some shortcomings. The position of the yarn needle cannot be flexibly adjusted according to the actual use needs, and the flexibility of use is poor. At the same time, when the yarn guide needle is damaged, the entire yarn guide seat needs to be replaced, which is time-consuming and laborious, and the production cost is high, and the scrap rate of the equipment is high. Unable to meet current usage needs
