Description

Pressure regulating locking mechanism for plate spring cradle of spinning machine Technical Field The utility model relates to the technical field of a plate spring cradle of a spinning machine, in particular to a pressure regulating and locking mechanism of the plate spring cradle of the spinning machine. Background The plate spring cradle of the spinning machine is an important component in a drafting mechanism of the spinning machine and is mainly used for controlling the yarn drafting process, and the plate spring cradle of the spinning machine is generally composed of a plate spring, a cradle body, a pressurizing device, an adjusting mechanism and the like, wherein the plate spring is a key component and is generally made of high-quality spring steel, and has good elasticity and strength; The leaf spring cradle realizes the pressurization of the roller through the elastic deformation of the leaf spring. When the cradle is installed on the spinning machine, the plate spring is subjected to a certain pretightening force, so that proper pressure is kept between the rollers. In the spinning process, as the yarn passes, the roller needs to draft the yarn, and the elastic force of the plate spring can ensure that the roller can stably apply uniform pressure to the yarn under different working states, so that the accurate control of yarn draft multiple is realized. However, in practice, it has been noted that the end of the whole leaf spring cradle is generally sleeved on a cylindrical fixing rod, then the connection between the end of the leaf spring cradle and the fixing rod is locked by using a compression rod and a fixing structure above the leaf spring cradle, the compression rod is pulled upwards, and the locking mechanism is opened, so that the cradle body swings in a fixed manner, and the contact position between the locking block inside the locking mechanism and the fixing connection is worn and loosened along with the frequent opening and closing actions of the cradle body, so that the internal locking mechanism needs to be replaced. Disclosure of utility model The utility model aims to provide a plate spring cradle pressure regulating locking mechanism of a spinning machine, wherein an arc-shaped clamping plate contacted with a fixing rod of the spinning machine is arranged in the plate spring cradle pressure regulating locking mechanism, friction force with the surface of the fixing rod of the spinning machine can be increased through mutual matching of the surface of the arc-shaped clamping plate and an anti-slip boss, so that a cradle shell is fixed on the fixing rod, the position of the arc-shaped clamping plate can be adjusted through threaded matching between a supporting rotating shaft and an adjusting screw rod, and abrasion clearance is compensated, so that the service life is prolonged.
