Abstract

The invention relates to a powder duster recycling and circulating system and belongs to the technical field of printing. An automatic powder sending, recycling and circulating device of the existing glitter powder machine is large in noise, distribution of wind power of a suction ventilator is unreasonable, and powder for printing is easily blocked. The powder duster is characterized in that due to the fact that a suction ventilator A is moved to the lower portion of the powder duster, noise decibels can be reduced; due to the fact that suction force of the suction ventilator A is larger than that of a suction ventilator B, printing materials are prevented from being absorbed by an upper powder suction hole; due to the fact that an air compensation channel is formed between a discharge pipe and a collecting powder recycling pipe, smooth flow of air-powder mixture is ensured; a bypass air outlet of the suction ventilator A is directed at the air compensation channel to assist the collecting powder recycling pipe in keeping smooth; and an air cylinder is used for supporting an upper rack, the route of the air cylinder can be set, adjustment of the position of an upper air suction hole can be achieved by controlling the air cylinder, and therefore time for adjusting the position of the upper air suction hole is reduced, and productivity of the powder duster is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a recycling system for a powder spreader. Background technique [0002] No. 200810161636.9 Chinese Invention Patent Specification discloses an automatic powder feeding recycling device for a glitter powder machine. After practical and analysis, it is found that it has the following technical defects: [0003] 1. The suction fans of the two air powder separators are located on the upper part of the equipment, and the noise is large; [0004] 2. Due to the unreasonable distribution of the suction fans of the two air-powder separators, the printed matter is easily absorbed by the upper powder suction port when it passes through the paper support wheel, and the upper powder suction port is blocked, which damages the printed pattern and becomes a waste product; [0005] 3. The connection between the powder collection hopper and the multi-stage recovery powder suction pipe is a close...
