A multi-adaptive creel for rotor spinning machine

Abstract

The invention relates to a multi-adaptive bobbin creel of a rotor spinning machine. The multi-adaptive bobbin creel of the rotor spinning machine comprises a left arm, a left pin roll, a left bearing, left top trays, right top trays, a left bearing, a right pin roll and a right arm, wherein a straight-edge bobbin mounting hole and a tapered bobbin mounting hole are arranged in the left arm; a right arm mounting hole I and a right arm mounting hole II are arranged in the right arm; one end of the left pin roll passes through left arm gaskets to be mounted in the straight-edge bobbin mounting hole or the tapered bobbin mounting hole, while the other end of the left pin roll is mounted on the left bearing to which the left top trays are fastened; one end of the right pin roll passes through right arm gaskets to be mounted in the right arm mounting hole I, while the other end of the right pin roll is mounted on the right bearing to which the right top trays are fastened; two sets of the left arm gaskets, the left top trays, the right arm gaskets and the right top trays are arranged; one set comprises a straight-edge bobbin left arm gasket, a straight-edge bobbin left top tray, a straight-edge bobbin right arm gasket and a straight-edge bobbin right top tray; the other set comprises a tapered bobbin left arm gasket, a tapered bobbin left top tray, a tapered bobbin right arm gasket and a tapered bobbin right top tray. The multi-adaptive bobbin creel of the rotor spinning machine is simple in structure, is convenient for realizing the replacement of a straight-edge bobbin and a tapered bobbin, is relatively high in the adaptability and the flexibility to a market, and effectively decreases the production cost.

Description

technical field [0001] The invention belongs to the field of spinning machinery and relates to a creel, in particular to a multi-adaptive creel for a rotor spinning machine. Background technique [0002] In the rotor spinning machine, the creel works together with the winding mechanism to support and fix the spindles and form different shapes. It works as figure 1 As shown: the spindle 2 is installed on the creel 1, the spindle 2 rotates around its own axis, the winding roller 3 rotates to drive the spindle 2 to rotate, so that the yarn 5 is wound on the spindle in an orderly manner under the joint action of the yarn guide mechanism 4 2 on. [0003] The structure of the creel to fix the spindle is as follows: figure 2 Shown: the spindle 2 is formed by winding the yarn 5 on the flat tube 8 . Left bearing pin 17 is housed in the creel left arm 6, and left bearing 15 is contained on the left bearing pin 17, and flat tube left top plate 11 fastens the outer ring of left bea...

Problems solved by technology

This method has the following disadvantages: 1) If the customer wants to change the type of spindle according to the market demand, and replace it with a flat tube or a cone tube, the left and right arms of the creel must be replaced, and the replacement of the left and right arms often requires the entire creel When disassembled from the machine, the installation accuracy of the left and right arms is high. The replaced left or right arm can only be idle and needs to be purchased. The entire replacement cycle is long, resulting in waste of idle time. Special skilled personnel are required to perform the replacement operation. Customers The cost of replacement is huge, and the flexibility to adapt to the market is low; 2) For manufacturers, since the left and right arms are the basic parts of the creel, and they belong to the front assembly parts in the assembly process, they belong to the front end of manufacturing. Orders are placed early, and the entire production cycle is long. When the customer's order is adjusted, the manufacturing and processing of parts and the assembly of the creel must be adjusted accordingly. The cycle is long, and the adjustment of unused parts will form inventory and generate costs. Therefore, the company's market demand Poor adaptability and flexibility
