Spring cradle

Abstract

The invention relates to a novel spring cradle. A compression seat is hinged on a cradle seat body, a connecting bolt penetrates through a fixed block in the cradle seat body and is screwed on a nut of the compression seat, the arc surface of the cradle seat body and the arc surface of the compression seat form a supporting rod shaft hole, and a raised V-shaped positioning block is arranged on the arc surface of the compression seat; a locking mechanism comprises a supporting sheet and a locking sheet; a pressing assembly comprises parallel brackets, leather roller seats, springs and pressure adjusting mechanisms; and the leather roller seats are arranged in the parallel brackets and guided by the parallel brackets, a leather roller claw connected with a leather roller shaft is arranged at the bottom of each leather roller seat, indicating plates of the pressure adjusting mechanism are arranged on the parallel brackets, pressure adjusting rods are connected with upper pressure adjusting blocks, the upper pressure adjusting planes of the upper pressure adjusting blocks in work are connected with the lower pressure adjusting planes of lower pressure adjusting blocks, pressure gear indicating marks are arranged on the indicating plates, and the springs arranged in the leather roller seats press against the lower pressure adjusting blocks. The spring cradle is reasonable in structure and simple and convenient in pressure adjusting operation, and leather rollers can keep parallel and have auxiliary pressure adjusting functions.

Description

technical field [0001] The invention relates to a novel spring cradle, which belongs to the technical field of pressure devices for cradles of ring spinning frames. Background technique [0002] The cradle pressurizing device used for ring spinning frame is mainly composed of cradle body, cradle seat, handle, and front, middle and back three pressurizing components. The pole shaft hole on the cradle seat is installed on the pole shaft, and the front, middle and rear pressure components are respectively installed under the cradle body. Each pressure component is equipped with a roller claw, which is connected to each leather The top rollers on the roller claws press the respective corresponding rollers. When working, the cradle handle and the cradle body, and under the action of their respective pressurizing components, press the front, middle and rear three top rollers against the respective corresponding rollers, so that A certain frictional force is generated between the ...

AI Technical Summary

Problems solved by technology

In the above structure, the top roller seat is movably arranged in the top roller seat, and the top roller seat is only limited by the guides on its side. Because there is a certain floating gap between the top roller seat and the pressurization seat, when the The rack handle is pressed down so that when the cradle pressurization device is in working condition, the top roller seat is in a floating position, so the parallelism of the top rollers can only be guaranteed by the manufacturing and assembly accuracy of the pressurization components, which will not only increase the manufacturing cost , and there is no guiding mechanism on the top roller shaft installed on the top roller seat, the size of the top roller claw bayonet of the top roller seat will change after long-term use, and it is impossible to ensure that the top roller seat can keep the top rollers and rollers parallel, and the yarn quality is difficult to control
