Embodiment 1

[0064] This embodiment aims at the inconvenient problem of manually adjusting the gap between the pressure rollers of the ring mold, and provides an adaptive adjustment device for the gap between the pressure roller and the ring mold. 4. Composed of counting mechanism 5, pneumatic transmission and distribution assembly 6, air motor 7, shield 8, pressure roller adjustment mechanism 9 and self-adaptive control system.

[0065] Device principle:

[0066] When the operator enters the adjustment command through the control system, the control system adjusts the air intake by controlling the opening and closing of the air circuit, and then drives the air motor to rotate. The displacement is converted into radial displacement to drive the pressure roller adjustment lever to move back and forth, and then drive the pressure roller adjustment arm to rotate, and then adjust the pressure roller to adjust the gap between the pressure roller and the ring die by adjusting the rotation of the...

Embodiment 2

[0080] In order to realize the self-adaptive adjustment of the pressure roller gap of the ring die, this embodiment provides a control method for the self-adaptive adjustment device of the pressure roller ring die gap, as follows:

[0081] First, the zero position is automatically adjusted according to the use of the pressure roller and the ring die. After the zero position is determined, the gap between the pressure roller and the ring die can be adjusted to increase or decrease. Assuming that the initial value of the pressure roller ring die gap is A0, the required pressure roller can be set according to the demand. If the gap value of the ring die is A, the control system will judge by itself.

[0082] When A>A0, the control system will control the air path to control the rotation of the air motor 7 through the air path transmission distribution component 6, and the air motor 7 drives the gear transmission mechanism 3 on the front plate to rotate through the transmission sha...

Abstract

The invention discloses a self-adaptive adjusting device for a gap between a compression roller and a ring die and a control method, and belongs to the technical field of grain feed processing equipment. Comprising a transmission shaft; the output end of the driving mechanism is connected with the transmission shaft to enable the transmission shaft to rotate; the input end of the gear transmission mechanism is connected with the transmission shaft; one end of the compression roller adjusting arm is connected with the output end of the gear transmission structure, and the other end of the compression roller adjusting arm is connected with the compression roller and can drive the compression roller to eccentrically rotate so as to adjust the gap between the compression roller and the circular mold; the counting mechanism is used for sensing the rotation amount of the output end of the driving mechanism; and the control system is used for controlling the rotation amount of the output end of the driving mechanism according to the set gap value and then controlling the eccentric rotation amount of the compression roller so as to adjust the gap between the compression roller and the ring die. The problem that manual adjustment of the gap between the ring die pressing rollers is inconvenient is solved, time is saved, safety is improved, and the use efficiency of equipment is improved.

Description

technical field [0001] The invention relates to a feed processing machine, in particular to a self-adaptive adjustment device and a control method for the ring die gap of a pressure roller of a granulator, and belongs to the technical field of grain and feed processing equipment. Background technique [0002] Feed pellet machine is divided into ring die feed pellet machine, flat die feed pellet machine, drum feed pellet machine. The working principle of the ring die feed pellet machine is: the ring die rotates under the driving force, the material layer is taken into the extrusion zone, and the pressure roller also rotates with the help of friction in the extrusion zone. Rotation, the extrusion force and the density of the material gradually increase, the material is squeezed into the die hole, and the material in the die hole is continuously extruded out of the die hole after being shaped to form cylindrical particles. [0003] At present, most of the gaps between the ring...
