Problems solved by technology

[0003] At present, the typical powdering methods include: the pulp filling method in the paper industry, that is, the filler is dispersed in water to make a suspension, and then it is mixed with the slurry evenly, and then it is made on a paper machine. During the molding process, the loss of filler is very large, and it is very difficult to increase the amount of filler

Abstract

The invention provides a powder sprinkling device which comprises a powder bucket (1), a shell (5), a metering roller (4), a connecting passage (6) and a vibrating screen (7), wherein the shell (5) is connected with one end of the powder bucket; the metering roller (4) is arranged in the shell and is in contact with the inner surface of the shell; the connecting passage (6) is arranged below the shell and is connected with the shell; the vibrating screen (7) is connected with the connecting passage and is arranged below the metering roller; and the metering roller is driven by a first driving device. Because the metering roller is driven by the first driving device, the powder sprinkling quantity can be set by setting the rotation speed of the first driving device.

Description

technical field [0001] The invention belongs to the field of papermaking and relates to a powder spreading device. Background technique [0002] Powder spreading devices are involved in many industries such as papermaking and tobacco. For example, in the papermaking industry, some mineral powder fillers, such as talcum powder and calcium carbonate, need to be added during the papermaking process to improve the performance of the paper and reduce the The cost of paper; in the tobacco industry, it is necessary to add tobacco powder directly between two layers of moist tobacco sheets to improve the utilization of tobacco powder. [0003] At present, the typical powdering methods include: the pulp filling method in the paper industry, that is, the filler is dispersed in water to make a suspension, and then it is mixed with the slurry evenly, and then it is made on a paper machine. During the molding process, the loss of filler is very large, and it is very difficult to increase...
