Description

Technical Field

[0001] The utility model relates to the technical field of quartz stone plate production, in particular to a resin quantitative feeding device used in the production of quartz stone plates. Background Art

[0002] Quartz slab is a kind of synthetic slab. During the processing, quartz is added to the resin material to make the slab have the effect of marble. There are certain requirements for the thickness and area of ​​quartz slabs. The specifications of the quartz slabs in the same batch need to be consistent, so the amount of quartz, resin, sand and other raw materials used must be mixed in proportion and then made into slurry. Therefore, before mixing, the resin needs to be added to the mixing box in a quantitative manner. When adding, it is necessary to weigh it manually with the help of a metering scale and inject it into the mixing box. In the process of adding resin, the resin raw materials with larger particles will take a long time to melt when heated and melted. Therefore, when adding, in order to ensure the heating and board making effect, the resin needs to be filtered, which greatly reduces the feeding efficiency of the resin. Utility Model Content
