Claim 6:
7. A continuous skin packaging and coating method for tablets, comprising the following steps:
(1) starting a lower coating film unreeling roller, a upper and lower composite coating film scrap edge reeling roller, and an upper coating film unreeling roller, passing a lower coating film sequentially through a channel between an upper heating plate and a lower heating plate of a lower coating film heating component, a tablet core implanting component, a first mold provided with a first tablet placing hole, a second mold provided with a second tablet placing hole, and a cutting component, passing an upper coating film sequentially through an upper coating film channel between a left heating plate and a right heating plate of an upper coating film heating component, a heat-sealing plate, the second mold, the cutting component, and a tablet pushing component;
(2) when the lower coating film moves to a station (a), passing the lower coating film through the lower coating film heating component while being heated and softened by the upper heating plate and the lower heating plate, and implanting a tablet core into the first tablet placing hole of the first mold via a vacuum tube of the tablet core implanting component, thus obtaining a half-finished skin packaged and coated tablet;
(3) moving the first mold downwards, and continuing to move the half-finished skin packaged and coated tablet rightwards;
(4) when the half-finished skin packaged and coated tablet moves rightwards to a station (d), entering, by the half-finished skin packaged and coated tablet, into the second tablet placing hole of the second mold, coating the upper coating film that is heated and softened by the upper coating film heating component on the upper surface of the half-finished skin packaged and coated tablet, and moving the second mold upwards to press a heat-sealing plate, compounding the tablet core with the upper coating film in the tablet placing hole of the bottom surface of the heat-sealing plate;
(5) moving the second mold downwards to obtain a coated tablet, and moving the coated tablets to a station (e); and
(6) starting the cutting component to cut the coated tablet from the heat-sealed upper and lower coating films, and then moving the coated tablet to a station (f), pushing the coated tablet into a collecting device by the tablet pushing component, obtaining a product, and reeling scrap edges by the upper and lower composite coating film scrap edge reeling roller.
