Detailed Description

For a better understanding of the objects, structures and functions of the present utility model, a feeding device according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a feeding device comprises a storage tank 1, wherein a feed inlet 6 is formed in the top of the storage tank 1, a cover plate 2 capable of being opened and closed is covered at the feed inlet 6, sealing of the feed inlet 6 is achieved, a conical structure is arranged at the bottom end of the storage tank 1, a discharge hole is formed in the lowest point of the conical structure, the discharge hole is connected with an inlet of a venturi pump 3, an outlet of the venturi pump 3 is connected with the front end of a conveying pipe 4, and the tail end of the conveying pipe 4 is inserted into the bottom of a sheet.

During the use, additive powder is put into storage tank 1 inside from feed inlet 6, afterwards get into venturi pump 3 department from the discharge gate, venturi pump 3 sends the additive into conveying pipeline 4, afterwards directly send to the bottom of piece material through conveying pipeline 4, realize the regulation of atmospheric pressure through control venturi pump 3 pneumatic valve, and then can control the additive addition, directly send the additive to the piece material bottom through conveying pipeline 4, the scattering of reducible piece material has not only alleviateed the pollution to the air, still reduced the loss of additive simultaneously, manufacturing cost has been reduced.
