Description

Conveyer belt powder paving device

Technical Field

The utility model relates to the technical field of powder paving equipment, in particular to a conveying belt powder paving device.

Background

At present, in the process of preparing food bars, chocolate bars, biscuits, candies, chocolate or powder and other products, materials are required to be mixed, or powder is required to be paved when mixed powder is conveyed, and four common powder supplying and paving modes are scraping plate type, roller type, movable hopper type and vibrating type. The movable raw material box moves from one end of the working platform to the other end, so that the powder spreading function of the workpiece box area is realized. The feeding rod pushes the powder into a workpiece processing area of the working platform, and compacts the powder while pushing the powder, so that the powder spreading function is realized. The scraper type powder spreading sieve runs above the workpiece processing area at a constant speed, and the powder spreading stepping motor alternately moves forward and reverse at a speed set by a program, so that powder arching is broken and powder spreading is realized. The vibration type powder supplying and paving device adopts a vibration sieve to sieve powder materials mixed by various powders, but the mixing state is easy to be damaged by mechanical vibration due to different powder densities, so that layering phenomenon is formed.

In the powder paving mode, the movable hopper type powder paving device mostly needs to drive the hopper to move, so that not only is a great deal of energy power consumed, but also the uniform implementation of powder paving is not easy to ensure. For roller type powder spreading, the roller needs to reciprocate, so that the working efficiency of the mode is slower, and the powder spreading effect is poor. The scraper blade that current is commonly used spreads powder and uses the scraper blade to move in turn around the conveyer belt to because the mixture of powder granule, in order to reach better shop powder effect, need reciprocal powder scraping many times in shop powder in-process, thereby cause shop powder inefficiency's condition, because the particle size of powder is different, can't guarantee at the shop in-process that the powder of minor diameter is laid evenly.
