Anti-blocking material conveyer

Abstract

The invention discloses an anti-blocking material conveyer. The anti-blocking material conveyer comprises a frame, the frame is provided with a driving mechanism and a screw connected to the driving mechanism, the screw is sleeved with a charging barrel, one end of the charging barrel is provided with a feed hopper, the other end of the charging barrel is provided with a discharge outlet, a spirally extended conveyer channel is disposed, between the feed hopper and the discharging outlet, in the periphery of the screw, the cross sectional area of the conveyer channel, close to the feed hopper is less than the cross sectional area of the other end. The volume of the conveyer channel spirally extended from and disposed to the periphery of the screw increases gradually from the feed hopper to the discharge outlet, the increased volume can prevent from short pause caused by split charging of material, powder or granule will not be extruded and caked even affected with damp, the conveyer process of the powder or granule is uniform in speed and smooth, accurately metering can be achieved in the subsequent split charging split charging operation, so the whole production line can continuously work at high efficiency.

Description

technical field [0001] The invention relates to a feeder, in particular to a material conveyor capable of preventing blockage. technical background [0002] At present, the conveyors used for conveying powder generally adopt screw-type conveying, and the screws are usually equal in diameter and pitch, and the cross-sectional areas of the helical grooves on the screw are equal everywhere. In the process of actually conveying the powder, the powder is squeezed due to friction on the inner wall of the barrel, and there is no extra space in the conveying channel to absorb and resolve the extrusion force, so that the powder is often in this Under the action of extrusion force, it will form a block and block the conveying channel, especially in wet days or when the powder itself is not dry enough. Downtime, affecting work efficiency. If the conveyor is used for subpackaging medicines, the consequences will be more serious, which will cause inaccurate doses of medicines taken by ...

AI Technical Summary

Problems solved by technology

In the process of actually conveying the powder, the powder is squeezed due to friction on the inner wall of the barrel, and there is no extra space in the conveying channel to absorb and resolve the extrusion force, so that the powder is often in this Under the action of extrusion force, it will form a block and block the conveying channel, especially in wet days or when the powder itself is not dry enough. Downtime, affecting work efficiency

If the conveyor is used for dispensing medicines, the consequences are more serious, causing inaccurate doses of medicines taken by patients.
