Moistureproof and leakproof feeding hopper for side feeding machine

Abstract

The invention discloses a moistureproof and leakproof feeding hopper for a side feeding machine, which takes a use direction as a reference and comprises a hopper body, a feeding barrel and a base, wherein the upper end of the hopper body is communicated with the lower end of the feeding barrel in a sealing manner; the lower end of the hopper body is communicated with the upper end of the base in a sealing manner; a plurality of through openings with filtering, drying and exhausting functions are formed in the hopper body; and an annular bayonet protruding from the end face of the lower end of the base is arranged at the lower end of the base. With the adoption of the moistureproof and leakproof feeding hopper, water vapor generated in the feeding hopper for the side feeding machine can be exhausted out timely; a material in a large supply hopper for the side feeding machine is prevented from being wetted and caked; and the material can be prevented from leaking from a part between the bottom end of the feeding hopper for the side feeding machine and a feeding inlet.

Description

technical field [0001] The invention relates to a feed hopper for a side feeder, in particular to a moisture-proof and leak-proof feed hopper for a side feeder. Background technique [0002] At present, in the production process of the extruder, the side feeder is often required to provide auxiliary feeding for the extruder, and the side feeder is a small device. In order to maintain the uniformity and stability of the feeding, it will A small feed hopper is set between the large hopper and the feeding port of the side feeder. The traditional side feeder feed hopper usually adopts a closed structure, that is, the material comes in from the large feed hopper, enters the feed hopper to the side The discharge process of the feeding port of the feeder is carried out in a closed environment.

Problems solved by technology

[0002] At present, in the production process of the extruder, the side feeder is often required to provide auxiliary feeding for the extruder, and the side feeder is a small device. In order to maintain the uniformity and stability of the feeding, it will A small feed hopper is set between the large hopper and the feeding port of the side feeder. The traditional side feeder feed hopper usually adopts a closed structure, that is, the material comes in from the large feed hopper, enters the feed hopper to the side The discharge process of the feeding port of the feeder is carried out in a closed environment. Since the material is powder in most cases, and the powder cannot be completely dry, it is more or less damp, and the side feeder works Under the action of high temperature, the powder material in the feeding hopper will be baked, and a certain amount of water vapor will be generated. However, the feeding hopper is closed, and the water vapor generated by heating cannot be discharged from the feeding hopper. It can evaporate upwards into the large feeding hopper where the material is stored. The large hopper is far away from the high temperature area of ​​the side feeder, usually at room temperature. In this way, once the water vapor enters the large hopper, it will be condensed and solidified into moisture, causing the powder material to be damp. Smaller agglomerates mixed with materials into the side feeder will lead to uneven mixing of the overall material and affect the quality of the product, while larger agglomerates may directly block the barrel mouth of the feed hopper. Cause the side feeder to break the material, or even directly lead to the production of unqualified products

In addition, the bottom opening of the feed hopper of the traditional side feeder and the feed port of the side feeder are usually connected in parallel, and then fixed by screws, but due to the vibration of the machine, the screws often loosen, making the feed hopper A gap is formed between the bottom opening and the feeding port of the side feeder, so that the material is exposed from the gap, resulting in material waste
