In addition, there will be inconsistent wear of the moving roller during use, such as the wear and tear in the middle of the moving roller, which will have a great impact on the size control of the discharge particle size. At present, manual inspection and manual repair are used after shutdown. Solution, this method of wear detection and repair of moving rollers is labor-intensive for workers, the control of the gap between the rollers is not precise and timely, and the system is unstable. It is especially not suitable for workplaces where the particle size of the crusher output changes frequently

[0031] Such as image 3 with Figure 4 Shown: The specific operations of the present invention are: the user input roll gap gap y, roll gap gap deviation value y1, the synchronization deviation value y2 of the first linear motor 1 and the fourth linear motor 4, PID control proportional, integral, Differential parameter, the distance deviation value x of the ultrasonic distance meter 12; judge whether the absolute value of the difference between the distance y3 and y4 measured by the displacement sensor 7 is less than the synchronization deviation value y2 of the first linear motor 1 and the fourth linear motor 4 ; If it is greater than y2, adjust the first linear motor 1 and the fourth linear motor 4 through PID control so that the difference is less than y2;
[0032] According to the formula d4=d-d1-d3-d5-d2-?x, where d is the distance from the tail of the hydraulic cylinder to the center of the fixed roller; d1 is the length of the hydraulic cylinder; d2 is the length measured ...

The invention discloses a device and a method for adaptive adjustment of a roller gap of a crusher. Hydraulic buffering systems and displacement sensors are arranged on two sides of a movable roller symmetrically; a plurality of ultrasonic range finders are mounted on a rack which is parallel to the movable roller; a first linear motor and a fourth linear motor are respectively and fixedly connected with adjustable bearing seats on two sides of the movable roller; the first linear motor and the correspondingly connected adjustable bearing seat are mounted on one same guide rail; the fourth linear motor and the correspondingly connected adjustable bearing seat are mounted on another same guide rail; a grinding wheel system is fixedly connected to a second linear motor mounted on a first guide rail; a third linear motor is mounted on a second guide rail, fixedly connected to the first guide rail, and between the first guide rail and the second guide rail; the first guide rail and the second guide rail are perpendicular to each other; and the first guide rail is parallel to the movable roller. The device and the method have the beneficial effects that the structure is simple; the precision is high; the maintenance cost is low; and the practical application value is high.
Description
Technical field [0001] The invention relates to a device and method for self-adapting adjustment of the gap between the rollers of a crusher, in particular to a device and method suitable for precise adjustment of the gap between the two-roller or four-roller crushing motorized roller and a fixed roller. Background technique [0002] In order to ensure the crusher's output particle size and the normal and reliable operation of the crusher, a roll gap adjustment device is installed on the crusher. Its function is to adjust the gap between the fixed crushing roller and the movable roller to meet the size requirements of the crusher's output particle size. . [0003] At present, manual or screw mechanism is usually used to realize the positioning of the crushing motor roller to realize the adjustment of the roll gap gap. After the roll gap gap adjustment is completed, the positioning stopper is used to locate the movable roller. In addition, the moving roller will have inconsistent w...
