Adjustable impact force device capable of effectively solving punching of screening machine

Abstract

The invention discloses an adjustable impact force capable of effectively solving punching of a screening machine. The adjustable impact force device comprises a stock bin, a feeding tube connected to a discharge hole of the stock bin, a decompression cone arranged below the feeding tube, and a control regulating structure for regulating a distance between the decompression cone and the bottom end of the feeding tube, wherein the feeding tube comprises an inner feeding tube and an outer feeding tube which is arranged at the periphery of the inner feeding tube and is concentric to the inner feeding tube; the outlet of the outer feeding tube is flexibly connected to a feeding hole of the screening machine; and the control regulating structure reduces control of punching impact force by regulating the distance between the decompression cone and the inner feeding tube. The adjustable impact force device regulates unloading amount by regulating a gap between the decompression cone and the inner feeding tube through a regulating guide rod, can be regulated to a proper position according to requirements, enables unloading to be uniform, greatly reduces impact force on a screen by reducing dropping height difference, shortens equipment maintenance time, and reduces maintenance cost.

Description

technical field [0001] The invention relates to the technical field of powder equipment, in particular to an adjustable impact force device that effectively solves the problem of material punching in a screening machine. Background technique [0002] In the uniform powder feeding equipment, the commonly used equipment includes rotary valves, screw feeders, vibrating feeders and other equipment, but the cost is high, the failure rate is high, and powder leakage or motor failures often occur. And because these equipment feed at a certain height above the screening machine, the height difference of the falling material will cause a certain impact on the screen of the screening machine, especially in the industry of water-containing materials, the impact of the height of water-containing materials on the screen is extremely obvious, this It is one of the important reasons for the frequent replacement of the screen of the screening machine. The vibrating feeder can only use the ...

AI Technical Summary

Problems solved by technology

The vibrating feeder can only use the vibrating motor to control the feeding amount, but the adjustment amount is limited, which cannot meet the fine feeding requirements. The uniform feeding amount of the rotary valve is controlled by the charging amount between the rotor blades and the frequency modulation of the frequency conversion motor. The screw feeder The uniform feeding amount is controlled by the charging amount between the worm blades and the frequency modulation of the frequency conversion motor, but the charging amount between the rotor blades and the worm blades is fixed, and the frequency modulation range of the frequency conversion motor is limited, and even under load, it cannot be used at low speed run, for fine-grained control

Especially in the lithium battery industry, these devices are all made of metal. Although they can be coated to isolate materials from contact, after a period of production, due to the wear and tear between the device itself and the materials and devices, a lot of magnetic foreign matter will be mixed in, which will seriously Affect product quality, at the same time, in the production process, these equipment will have problems such as powder leakage, which will pollute the workshop
