Pressurized rocking frame of ring spinning frame drafting system

Abstract

The invention relates to a pressurized rocking frame of a ring spinning frame drafting system. The pressurized rocking frame comprises a rocking frame base and a rocking frame body, wherein the rocking frame body is arranged on the rocking frame base. The pressurized rocking frame further comprises multiple air cylinder pressurizing devices, wherein the multiple air cylinder pressurizing devices are arranged and installed on the rocking frame body and comprise assembling supports, air cylinders, pistons with rods, pressurizing rods and holding jaws. The assembling supports are fixed on the rocking frame body through bolts, the air cylinders are fixed on the assembling supports, the piston ends of the pistons with the rods are arranged in the air cylinders, the other end of each of the pistons with the rods are arranged above the pressurizing rods, the pressurizing rods are located under the air cylinder, the holding jaws are arranged on the pressurizing rods, and the air cylinders of the air cylinder pressurizing devices are respectively provided with an independent air pressure source connecting end. By adopting the pressurized rocking frame, the consistency of pressurized pressure of each rocking frame set is improved, unified pressure regulation and stepless pressure regulation of the same pressurized positions of all of rocking frames of a whole machine can be achieved, and the spinning quality is improved. In addition, the production efficiency is effectively improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of ring spinning machine equipment, in particular to a pressurized cradle used for the drafting system of the ring spinning machine. Background technique [0002] Ring spinning is to gradually elongate and thin the fiber bundles through the drafting system, and form yarns for weaving after twisting. The drafting system is the core part of ring spinning. To achieve the drafting of fiber bundles Stretching, there must be several pairs of rollers to hold the fibers to form the gripping jaws. To form the gripping jaws, the rollers must be pressurized. The cradle is the part that fixes the top roller and applies pressure to the rollers. In the prior art, the cradle pressurizes the rollers in the form of coil spring pressurization, leaf spring pressurization, airbag pressurization and the like. [0003] The drafting system of each spinning frame or roving frame includes at least dozens of cradles and as many as six or seve...

AI Technical Summary

Problems solved by technology

[0004] In the coil spring pressurizing device and leaf spring pressurizing device in the prior art, the pressurizing force depends on the compression amount of the coil spring or leaf spring, and it is necessary to carefully adjust the working height of the cradle set by set, so that the The pressure of each set of cradles in the whole vehicle tends to be consistent, and the working height of the cradle needs to be adjusted after the top rollers are sharpened to compensate for the pressure loss caused by the change in the diameter of the top rollers. Only skilled employees can complete it. At the same time, these two pressurization methods cannot realize collective pressure regulation, semi-pressure relief and stepless pressure regulation, which greatly limits the adaptability of the cradle to the spinning process, and also increases a lot of yarn The workload of line joints and pressure adjustment

[0005] Although the airbag pressurization cradle of the prior art has functions such as collective pressure regulation, stepless pressure regulation, and half pressure release of the entire vehicle, each pressurization zone can only increase or decrease the pressure simultaneously in the same proportion. , so that the flexibility of pressurization is greatly reduced, and the spinning process is therefore limited, and the working height still needs to be adjusted one by one. Consistency is difficult to guarantee
