Further, the blanking opening is a conical opening with the large end facing upwards, and the large end of the horn tube faces downwards.

Further, the outer part of the horn tube is sleeved with a dust cover.

Further, the telescopic pipe is an elastic rubber corrugated pipe.

Further, an electric dust butterfly valve is arranged at the inlet end of the blanking pipe.

Further, the conical material receiving pipe comprises an annular ring and a conical pipe fixedly connected below the annular ring, and an annular groove matched with the opening of the material receiving barrel is formed in the bottom of the annular ring.

By adopting the technical scheme, the invention has the advantages that: the invention has compact design, high efficiency and high automation degree. The blanking port of the movable plate is designed to be a conical port with the large end upwards, and the bottom of the movable plate is fixedly connected with the horn pipe, so that the smooth degree of powder conveying is ensured, and the blockage caused by powder accumulation at the movable plate is avoided. In addition, the conical material receiving pipe matched with the conical material receiving pipe is fixedly arranged at the opening part of each material receiving barrel, and the conical material receiving pipe are completely attached through the air cylinder during discharging, so that dust emission in the discharging process is prevented, and the pollution to the working environment is avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.

Embodiments of the invention: the structure schematic diagram of the continuous automatic powder feeding device is shown in fig. 1-4, and the continuous automatic powder feeding device comprises a frame 1 and a belt conveyor 4 fixedly arranged below the frame 1, a top plate 2 fixedly connected with the top of the frame 1, a feeding pipe 6 fixedly arranged on the top plate 2, the lower end of the feeding pipe 6 penetrates out of the bottom of the top plate 2, a telescopic pipe 7 fixedly connected with the lower end of the feeding pipe 6, a movable plate 8 fixedly connected with the lower end of the telescopic pipe 7, a feeding opening 14 arranged in the center of the movable plate 8, a horn pipe 9 fixedly connected with the bottom of the feeding opening 14, a conical discharging pipe 11 fixedly connected with the lower end of the horn pipe 9, a pair of cylinders 14 fixedly arranged at the bottom of the top plate 2, telescopic rods of the cylinders 14 fixedly connected with the movable plate 8, a group of charging barrels 5 arranged on the belt conveyor 4, and a conical connecting pipe 10 matched with the conical discharging pipe 11 fixedly arranged at the opening of each charging barrel 5.

The blanking opening 14 is a conical opening with the large end facing upwards, and the large end of the horn tube 9 faces downwards. The outside cover of horn 9 has dirt proof boot 12, avoids the dust to give off to the air in, influences operational environment. The telescopic pipe 7 is an elastic rubber corrugated pipe and can stretch along with a telescopic rod of the air cylinder 14. An electric dust butterfly valve 3 is arranged at the inlet end of the blanking pipe 6. The conical receiving pipe 10 comprises an annular ring 101 and a conical pipe 103 fixedly connected below the annular ring 101, and an annular groove 102 matched with the mouth of the receiving barrel 5 is formed in the bottom of the annular ring 101.

The working principle of the invention is as follows:

during discharging, firstly, a conical material receiving pipe 10 matched with a conical material discharging pipe 11 is fixedly arranged at the opening part of each material receiving barrel 5, the conical material receiving pipe 10 is directly clamped at the opening part of the material receiving barrel 5 through an annular groove 102, then the material receiving barrel 5 is conveyed to the position right below the conical material discharging pipe 11 through a belt conveyor 4, at the moment, a telescopic rod of an air cylinder 14 stretches out, the conical material discharging pipe 11 descends to the position of the material receiving barrel 5 until the conical material discharging pipe 11 is completely attached to the conical material receiving pipe 10, then an electric dust butterfly valve 3 is opened, powder sequentially passes through the material discharging pipe 6, the telescopic pipe 7, a material discharging opening 14, a horn pipe 9, the conical material discharging pipe 11 and the conical material receiving pipe 10 to enter the material receiving barrel 5, after the material receiving barrel 5 is filled, the material receiving pipe 10 can be taken down, the material receiving barrel 5 is conveniently packaged, then the electric dust butterfly valve 3 is closed, and then the telescopic rod of the air cylinder 14 is retracted to the original position, and one-time powder filling work is completed.
