Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
Its embodiment, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution:A kind of stone countertops automatic production line, including raw material
Storage and feed proportioning system 1, stirring system 2, mixing system 3, cloth system 4, compact system 5, curing system 6 and material conveying skin
Band machine 7, raw material storage and feed proportioning system 1 are arranged in 7 left end of material conveying belt feeder, stirring system 2, mixing system 3, cloth system
System 4, compact system 5 and curing system 6 are arranged in successively on material conveying belt feeder 7.
