Roller protection device based on centrifugal deceleration for paper machines

Abstract

The invention discloses a roller protection device based on centrifugal deceleration for paper machines. The roller protection device includes a protection structure, a paper machine pressure roller,a pressure roller support frame, a fixed base, a pulse controller, a conveyor belt protection cover and a compression block. The roller protection device is equipped with an over-speed protector. Through a deceleration mechanism and a centrifugal drive structure, when the drive speed of the motor is too high, the over-speed protector can produce resistance to reduce the speed and ensure that the paper machine pressure roller works at a safe speed. Thus, the surface of the paper machine pressure roller after high-speed rotation is prevented from deforming by heat, the paper machine pressure roller is prevented from falling off due to shaking during rotation, the quality of paper dehydrated by the pressure roller is ensured, and the service life of the paper machine is prolonged.

Description

technical field [0001] The invention relates to a pressure roller protection device, in particular to a pressure roller protection device for a paper machine based on centrifugal deceleration. Background technique [0002] The function of the press part of the paper machine is to dehydrate the wet paper. The press roll of the paper machine is an important component of the press device of the paper machine. There are potential safety hazards during the high-speed operation of the press roll, and it is very easy to cause safety accidents such as limbs and clothes being involved. The lives of employees pose certain safety threats, so protective devices are needed to ensure the safety of employees in the production process. When the pressure roller rotates at a fast speed and rotates at a high speed for a long time, a large amount of heat is generated on the surface of the pressure roller, so the rubber of the pressure roller is deformed when heated, and the thickness of the pap...

[0002] The function of the press part of the paper machine is to dehydrate the wet paper. The press roll of the paper machine is an important component of the press device of the paper machine. There are potential safety hazards during the high-speed operation of the press roll, and it is very easy to cause safety accidents such as limbs and clothes being involved. The lives of employees pose certain safety threats, so protective devices are needed to ensure the safety of employees in the production process. When the pressure roller rotates at a fast speed and rotates at a high speed for a long time, a large amount of heat is generated on the surface of the pressure roller, so the rubber of the pressure roller is deformed when heated, and the thickness of the paper sheet after being pressed by the deformed pressure roller is different, which affects the quality of the paper. At the same time, due to the different heating temperature and deformation range of different positions, the pressure roller will vibrate during the rotation process and become a large vibration due to high-speed inertia. In severe cases, the pressure roller will be detached and cause damage to the paper machine. service life
