Stepless pressure regulating pneumatic pressure cradle

Abstract

Disclosed is a stepless pressure regulating pneumatic pressure cradle. The stepless pressure regulating pneumatic pressure cradle relates to the technical field of textile machinery, in particular tothe stepless pressure regulating pneumatic pressure cradle. The stepless pressure regulating pneumatic pressure cradle comprises a handle and a cradle body which penetrate through a handle shaft and are connected with one another, a lever and a clamping sleeve which are installed at the front end of the cradle body and in contact with one another, and a cradle body shaft which penetrates through the cradle body and a supporting frame; the supporting frame and a supporting base are connected through a fastening bolt. The stepless pressure regulating pneumatic pressure cradle is characterized inthat three groups of stepless pressure regulating assemblies are arranged in an inner cavity of the cradle body, the stepless pressure regulating assemblies comprise pressure seats installed at the bottom of the inner cavity of the cradle body, limiting pins and fixing pins are installed at the lower ends of the pressure seats, the fixing pins penetrate through central holes at head ends of broken line type pressure rods, tail ends of the broken line type pressure rods are connected with positioning device assemblies, the upper ends of the pressure seats are provided with pressure regulatingscrews and pressure regulating nuts, the lower end surfaces of the pressure regulating screws are in contact with the upper planes of the broken line type pressure rods, and socket head cap screws penetrate through the cradle body and are connected with the pressure seats; long grooves are formed in the rear surface of the cradle body. The stepless pressure regulating pneumatic pressure cradle hasthe advantages of being simple in overall structure, and convenient to install, use, adjust and maintain..

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a stepless pressure regulating pneumatic pressure cradle. Background technique [0002] Spinning cradle is one of the most direct and important components of yarn output in the process of ring spinning. Its performance has a direct impact on the spinning index, especially when the spinning process changes. , The convenience of distance adjustment, the long-term working stability of the cradle and the consistency of the performance indicators of the cradle when used in large quantities put forward higher requirements. The existing cradles in the market are mainly spring-loaded cradles and lever-type pneumatic cradles. Due to the limitation of spring materials and machining accuracy, the working pressure of different cradles varies significantly, and due to the limited spring resistance. The continuous attenuation seriously affects the long-term stability and service lif...

AI Technical Summary

Problems solved by technology

The existing cradles in the market are mainly spring-loaded cradles and lever-type pneumatic cradles. Because the spring-loaded cradles are limited by the spring material and processing accuracy, the working pressure difference between different cradles is obvious, and due to the spring resistance The continuous attenuation has seriously affected the stability and service life of the cradle for long-term use, thereby affecting the stability and improvement of spinning quality; Figure 5 As shown, the pressure and gauge adjustment of the lever-type pneumatic pressurized cradle is relatively cumbersome, and the pressure is balanced and distributed by the lever. It is impossible to adjust the pressure of a certain top roller according to the need, so as to ensure that the pressure meets the process requirements, so it is limited In addition to the adaptability to the spinning process, it also cannot meet the requirements of stable and improved yarn quality.
