Abstract
A plate spring cradle pressure adjusting and locking mechanism of a cotton spinning machine comprises locking pieces, a locking nut, a locking screw, a pressure adjusting nut and a pressure adjusting screw, the end of the locking nut and the end of the pressure adjusting nut are hinged between the two locking pieces, the included angle alpha between the axis of the locking screw and the horizontal line is 22 degrees, and the included angle beta between the axis of the locking screw and the axis of the pressure adjusting screw is 35 degrees; an arc-shaped groove is formed in the inner wall of a shaft hole in the locking piece, an arc-shaped gap is formed between the inner wall of the arc-shaped groove and the outer wall of the cradle supporting rod shaft, and the locking piece and the pressure adjusting screw are arranged on the side close to the arc-shaped gap. An arc-shaped notch I and an arc-shaped notch II are sequentially formed in the outer contour of the locking piece above the locking screw from top to bottom, and the arc-shaped notch I and the arc-shaped notch II are used for clamping a positioning roller on the rear portion of the handle and providing two gears for lifting of the handle and the rocker arm. The roller lifting device is reasonable in structural design, convenient and fast to install, debug and overhaul, capable of saving a large amount of cost, firm and stable in locking and large in lifting angle, a worker can clean a roller below conveniently, and interference cannot be brought to the worker.
Description
technical field [0001] The invention relates to a cradle in a cotton spinning machine, in particular to a pressure regulating and locking mechanism for a leaf spring cradle of a cotton spinning machine. Background technique [0002] As we all know, the cradle on the spinning machine is also called the drafting and pressing device. Its structure mainly includes a handle, a rocker arm and a cradle seat. The handle is located above the rocker arm, and the rocker arm is located above the cradle seat. On the rocker arm, the rear part of the rocker arm is hinged on the cradle base, and the lower part of the rocker arm is provided with front roller claws, middle roller claws and rear roller claws sequentially along its length direction. A pressure component is installed between the roller jaw and the rocker arm, and the pressure component usually has two forms of spring pressure and pneumatic pressure. When working normally, the cradle seat is fixedly installed on the main shaft o...
