Description

Technical Field

[0001] The utility model belongs to the technical field of equipment ventilation adjustment, and in particular relates to an adjustment device for the air volume of a cover conveying system. Background Art

[0002] The cap hopper used in the cap conveying system of beer filling production generally uses a high-power fan to convey bottle caps, pull-ring caps and other caps by air supply. The fan inlet is equipped with a filter to eliminate most of the dust and other impurities in the air to ensure the safety and hygiene of the air for cap delivery. Since the fan of the cap conveying system runs at full speed during the production process and there is no frequency conversion control, the size of the fan inlet air volume cannot be adjusted, resulting in the fan often conveying pull-ring caps at a constant maximum air volume. The pull-ring cap itself is made of a soft material. When the air volume is large and the number of caps delivered is large, the backlog between the pull-ring caps will cause some of the pull-ring caps to deform, which is easy to cause the small funnel of the cap sorter to be blocked or stuck, and then stuck in the turntable cap outlet and the lower cap guide rail, eventually causing the cap conveying system to stop due to cap jam. Therefore, manual on-site processing is required, and production efficiency is reduced.

[0003] The defect of the fan air volume of the cap conveying system cannot be adjusted, which greatly increases the number of equipment failures and failure time, seriously affects the equipment operation and production efficiency, and also increases the process risk. At present, there is a lack of an air volume adjustment device for the cap conveying system to control the air volume at the fan inlet and avoid large air volume conveying caps to the greatest extent.
