Adjustable uniform feeding device

Abstract

The invention discloses an adjustable uniform feeding device. The adjustable uniform feeding device comprises a feeding port, a feeding pipe connected with the feeding port, a pressure reduction conearranged under the feeding pipe, and a control adjusting structure used for adjusting the distance between the pressure reduction cone and the bottom end of the feeding pipe. A discharging pipe arranged at the bottom end of the feeding pipe and located on the periphery of the pressure reduction cone is further included. The feeding pipe comprises an inner feeding pipe body and an outer feeding pipe body which is arranged on the periphery of the inner feeding pipe body and is concentric to the inner feeding pipe body. The control adjusting structure achieves feeding amount uniform control through adjusting the distance between the pressure reduction cone and the inner feeding pipe body. An adjusting guide rod is used for adjusting the gap between the pressure reduction cone and the inner feeding pipe body, accordingly, the discharging amount is adjusted, the proper position can be adjusted according to needs, discharging is uniform, multi-level seal is adopted, and it is guaranteed thatmaterials do not leak.

Description

technical field [0001] The invention relates to the technical field of powder equipment, in particular to an adjustable uniform feeding device. 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. 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...

[0002] In the powder uniform 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

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
