Description

Material scraping device

technical field

The utility model relates to a packaging machine assembly, in particular to a material scraping device.

Background technique

Deoxidizers, preservatives and other products are mostly circulated in the market in the form of quantitative small packages. In order to measure accurately, the existing granule and powder packaging machines generally use a measuring cup for measurement; traditional powder granule packaging machines include material trays, The measuring cup, hopper and material scraper installed on the material tray, when the material in the material tray is short of material or less, the staff directly feed into the hopper, the material enters the material tray from the outlet of the hopper, the material tray rotates, and the material is scraped The material is guided in the material tray so that the material just fills the material cup until the feeding is completed.

However, the length of the existing material scraper cannot be adjusted. Due to the special material of the deoxidizer, the material scraper is prone to wear when the packaging machine is in continuous operation. If the scraper is not replaced in time, the weight of the deoxidizer will be unstable during the production process; and when the scraper is worn out, the entire scraper needs to be replaced, resulting in waste of the scraper and increased production costs.
