Precision feeding and dustproof distribution double-roller machine

Abstract

The invention belongs to the field of feeding double-roller crushing devices, and relates to a precision feeding and dustproof distribution double-roller machine. The machine comprises a pair of crushing rollers. The machine is characterized in that a dustproof cover is arranged at the periphery of the pair of crushing rollers; a discharge port is formed at the bottom of the dustproof cover; a hopper is mounted at the upper part of the dustproof cover, and communicates with the dustproof cover; the length direction of the hopper extends in the axial directions of the crushing rollers; the length of the hopper is matched with the lengths of the crushing rollers; a distribution auger is arranged at the lower part in the hopper; the axis of the distribution auger is parallel to the axes of the crushing rollers; the length of the distribution auger is the same as those of the crushing rollers; and a motor I is arranged at one end of the distribution auger. The machine is reasonable in structural design, and spiral sealing feeding is adopted, so that material dust is capable of being prevented from overflowing, a material is capable of being uniformly conveyed to the gap between the crushing rollers, the situations that the middle parts of the crushing rollers are seriously worn and the service life is shortened can be avoided; the crushing effect can be ensured; the crushing efficiency can also be improved; and the material can be accurately fed by adjusting the rotating speed of the distribution auger.

Description

technical field [0001] The invention relates to a precise feeding dust-proof cloth pair roller machine, which belongs to the field of feeding pair roller crushing devices. Background technique [0002] At present, most of the feeding rollers are open. During the high-speed crushing process, there will be continuous overflow of dust from the open feeding inlet, which will affect the environment. If the feeding inlet is sealed and the air is not circulated, it will hinder the conventional feeding. Function: the new roller or the grinding roller, the roll gap is straight, and the size of the roller gap determines the crushing force, and the current conventional feeding method is to directly feed the material from the middle position above the feed inlet to the roller In the gap between the rollers, the material mainly falls into the middle of the pair of rollers, and the feeding is uneven, forming a crushing impact, and because the materials are concentrated in the middle of th...

[0002] At present, most of the feeding rollers are open. During the high-speed crushing process, there will be continuous overflow of dust from the open feeding inlet, which will affect the environment. If the feeding inlet is sealed and the air is not circulated, it will hinder the conventional feeding. Function: the new roller or the grinding roller, the roll gap is straight, and the size of the roller gap determines the crushing strength, and the current conventional feeding method is to directly feed the material from the middle position above the feed inlet to the roller In the gap between the rollers, the material mainly falls into the middle of the pair of rollers, and the feeding is uneven, forming a crushing impact, and because the materials are concentrated in the middle of the pair of rollers (such as Figure 4 ), causing the middle part to wear fast, affecting the crushing gap, which not only reduces the life of the rollers, but also affects the crushing effect; and the material accumulates in the middle of the rollers, and the crushing efficiency is limited
