Technical Field

The invention relates to a cradle used for a spinning machine, in particular to a front-back pressurizing combined piece of a plate spring cradle.

Background

The cradle is an important component of the spinning traction device. Uneven pressure between the cradles can cause differences in yarn density, evenness, strength, butt, detail, neps, etc., and spindles with lower pressure can form yarn defects to affect yarn quality.

At present, Chinese patent with application number 202020795165.3 on the market discloses a pressure regulating mechanism for a leaf spring cradle of a spinning machine, which comprises a support, a leaf spring, a leather roller holding seat and a pressure regulating block, wherein the pressure regulating block consists of a cylinder capable of being fixed and a quadrilateral body with unequal distances from four sides to a circle center, and the pressure regulating block changes the contact surface of the quadrilateral body and the leaf spring by rotating the cylinder to achieve the purpose of regulating the deformation of the leaf spring. Although the structure of the adjusting mode is simple, the installation is difficult, and the plate spring can be installed only by pressing through a tool when being in a small deformation state; moreover, the adjusting blocks are limited in structure, only four sizes can be adjusted, and the adjusting range is small; in addition, the adjusting block is a special part, and the manufacturing cost is high.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a front and rear pressurizing combining piece of a plate spring cradle, which can randomly adjust the deformation of a plate spring according to requirements and has lower cost.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a pressurization conjunction around leaf spring cradle, includes that support, leaf spring and leather roller grip the seat, the front end and the leather roller of leaf spring grip the seat and be connected, the tail end is buckled into the U-shaped and is arranged in the support, threaded connection has adjustable pressure screw on the support, the free end of pressure screw offsets with the tail end of leaf spring.

The invention is further configured to: a fixed block is arranged between the inner wall of the bracket and the plate spring and sleeved on the pressurizing screw;

the length of the fixing block is equal to or slightly less than the inner width of the bracket.

The invention is further configured to: the other end of the pressure spring opposite to the plate spring is connected with an anti-skid block, and anti-skid lines are arranged on the end face, attached to the anti-skid block, of the fixing block.

The invention is further configured to: one end of the pressure spring, which is opposite to the plate spring, is connected with a balance pad, and the length of the balance pad is equal to or slightly less than the inner width of the bracket.

The invention is further configured to: the top wall of the support is provided with a first through hole and a second through hole, and the first through hole and the second through hole are drawn and tapped.

The invention has the advantages that after the plate spring is arranged in the bracket, the plate spring can be fixed only by screwing the pressurizing screw into the fixing block; the screw-in depth of the screw can adjust the deformation of the plate spring at will according to the requirement; the compression screw can be purchased as a standard part, and the cost is lower.
