A method for controlling material shredding with two-axis differential speed

Abstract

The invention discloses a double-shaft differential material shredding control method. The double-shaft differential material shredding control method comprises the following steps that a first driving mechanism drives a first driving shaft provided with a first cutter to rotate, and a second driving mechanism drives a second driving shaft provided with a second cutter to rotate. Speed difference exists between the rotation speed of the first driving shaft and the rotation speed of the second driving shaft, and the magnitude relation between the rotation speed of the first driving shaft and the rotation speed of the second driving shaft is adjusted alternately according to preset requirements. The shredding effect of materials can be ensured by adopting the double-shaft differential material shredding control method, the shredding efficiency of the materials can be ensured, the production yield of equipment can be increased, and the material shredding range of the equipment is widened. In addition, on the premise that the shredding effect and shredding efficiency of the materials are ensured, the interval between the adjacent cutters on the driving shafts can be enlarged to 3-5 mm correspondingly, the requirements for materials of the cutters on the driving shafts can be lowered correspondingly, and the manufacturing cost is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of material crushing, in particular to a method for controlling material shredding with two-axis differential speed. Background technique [0002] Currently, for the first recycling and crushing of materials such as automobile casings, waste household appliances, color steel tiles or aluminum profiles, twin-shaft shredders are used for crushing. In the process of crushing materials, double-shaft shredders often use the same speed control method to cut and shred materials, or use fixed differential speed control to cut and shred materials. The same speed control mode refers to driving the first shaft and the second shaft to cut and shred the material between the first cutter body of the first shaft and the second cutter body of the second shaft at the same speed; the fixed differential speed control mode refers to The purpose is to drive the first shaft and the second shaft to rotate, and to maintain a fixed...

Problems solved by technology

[0003] However, the disadvantage of the same-speed control method is that the materials to be shredded and pulled down are large in size. Under the premise of ensuring the shredding effect of the materials, the gap between adjacent cutter bodies needs to be strictly set to about 0.3mm. High precision requirements

The disadvantages of the fixed differential speed control method are: the tip of the cutter body of the axis with a higher speed is often accompanied by materials, and the materials attached to the tip of the cutter body are difficult to clean and will affect the efficiency of shredding materials. Under the premise of ensuring the shredding effect of the material, the gap between adjacent cutter bodies needs to be strictly set to about 0.3mm, so that the precision of the cutter body is required to be high
