Spun yarn straight pressure type spring pressurizing cradle

Abstract

The invention discloses a spun yarn straight pressure type spring pressurizing cradle used in yarn spinning equipment. A cradle body is hinged in an upper clamping supporting seat. A handle is hinged in the cradle body. The lower side of the cradle body is provided with at least two groups of pressurizing assemblies. According to the structure of each pressurizing assembly, a pressurizing seat is arranged in the cradle body, a leather roller holding clamp claw is movably arranged in an inner cavity of the pressurizing seat, a spring is arranged between the leather roller holding clamp claw and the top of the inner cavity of the pressurizing seat, two sides of the lower end of the pressurizing seat are respectively provided with open slots matched with a leather roller shaft in size, a locking crank is fixedly connected in the upper clamp supporting seat, a circular-arc clamp groove is formed under the front end of the locking crank, the handle is closed to enable the circular-arc clamp groove to be buckled with a pressure pin sleeve at the lower end of the handle, a step-shaped clamp groove is arranged at the back end of the locking crank, and a tail pin at the back end of the handle is buckled with the step-shaped clamp groove. The spun yarn straight pressure type spring pressurizing cradle is high in precision of three line parallelism depth, good in spinning quality, high in efficiency, and convenient to operate.

Description

technical field [0001] The invention relates to a drafting and pressurizing device used in spinning frames of textile equipment, and more particularly to a spun yarn direct pressure spring pressurized cradle. Background technique [0002] The structure of the current spun yarn direct pressure spring-loaded cradle is as follows: the cradle body is hinged in the upper card support of the holding seat, the handle is hinged in the cradle body, and at least two groups of pressurized components are installed on the lower side of the cradle body , the structure of each group of pressurized components includes a pressurized seat, a top roller holding claw and a spring, the pressurized seat is installed in the cradle body, the top roller holding claw is movably set There is a spring between the upper end of the holding claw and the top of the inner cavity of the pressurized seat, and the holding claw of the top roller can move vertically up and down along the inner cavity wall of the...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of the spun yarn direct pressure spring pressure cradle with the above structure are: the top roller holding claw is movable and arranged in the pressure seat, and there is a certain floating between the top roller holding claw and the pressure seat. Clearance, when the cradle is working, the claws of the top rollers are in a floating position, it is difficult to ensure the parallelism requi
