Shown in Fig. 1, in thermoprint process, gap (as shown in EA in Fig. 1) must be there is on operating path between adjacent two sheets 11, and in each sheet of printing stock, hot stamping pattern is also often just distributed in the subregion of stock, and (region of this part is called thermoprint region, as the KG region in Fig. 1 or BC region, HK, GE, AB, CD in Fig. 1 are not thermoprint regions), between the front end in thermoprint region 12 and the forward position of stock 11 from a distance, between the rear end in thermoprint region and the rear edge of stock also from a distance.Shown in Fig. 1, in present specification, the cusp position served as a contrast in eindruckwerk under roller 41 and roller platen 42 stitching state is called " pressing point " (the F point as in Fig. 1), stock 11 in thermoprint process is called " stock forward position " (as the A point in Fig. 1 or H point) at first through the position of eindruckwerk pressing point, position stock in thermoprint process being eventually passed eindruckwerk pressing point is called " after stock edge " (as the E point in Fig. 1 or D point), stock thermoprint region in thermoprint process is called " front end in thermoprint region " (as the K point in Fig. 1 or B point) at first through the position of eindruckwerk pressing point, position stock thermoprint region in thermoprint process being eventually passed eindruckwerk pressing point is called " rear end in thermoprint region " (as the G point in Fig. 1 or C point), distance length between " front end in thermoprint region " and " rear end in thermoprint region " is called " thermoprint zone length ", as the length of BC or KG in Fig. 1, distance length between " stock forward position " and " front end in thermoprint region " is called " front neutral gear length ", as the length of AB or HK in Fig. 1.After the hot stamping pattern of stock has designed, position on the substrate, thermoprint region has just been decided, and the numerical value of " thermoprint zone length ", " front neutral gear length " is also just decided.
There is following limitation and deficiency in current sheet cold foil technology: shown in Fig. 1, (namely do not need to shift the thermoprint material bed stage owing to there is certain neutral gear stage between twice, front and back hot stamping pattern KG and BC, as the GB stage in Fig. 1), comprise gap (the front neutral gear existed between " stock forward position " and " front end in thermoprint region ", as shown in AB in Fig. 1), clearance distance (the rear neutral gear existed between " after stock edge " and " rear end in thermoprint region ", as shown in GE in Fig. 1), also gap (the central idle existed between two sheet of printing stock, as shown in EA in Fig. 1), and in cold wave process, the stamping systems film of rolling always ceaselessly runs forward, so, the thermoprint material bed (as aluminium coated) of the stamping systems film that above-mentioned neutral gear place is corresponding is not transferred on sheet, directly swept away by useless film wrap-up and become useless film, cause waste, the utilization rate of stamping systems film is very low, increase cold wave cost.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind of sheet cold foil technology, it can save stamping systems film, improves the utilization rate of stamping systems film.
Its object can realize by following scheme: this sheet cold foil technology comprises the following steps:
(1), choose and determine the size dimension of every sheet of printing stock, designing the position of hot stamping pattern, shape and size;
(2), stamping systems film unreeling structure constantly discharges stamping systems film, and stamping systems film runs between the lining roller of eindruckwerk and roller platen; Coating mechanism coats adhesive in the thermoprint region of every sheet of printing stock, then held in the mouth by the paper-transferring gripper of chart driving mechanism, to the lining roller transmission of eindruckwerk, groove is provided with in the lining roller of eindruckwerk, be provided with in groove and hold mechanism of paper in the month, when the paper-transferring gripper of chart driving mechanism run to lining roller groove hold mechanism of paper side in the month time, stock is connect away by the mechanism of paper of holding in the month serving as a contrast roller groove; The mechanism of paper of holding in the month of lining roller groove drives stock to rotate advance; During normal impression, roller platen compresses lining roller and synchronous axial system, stock and stamping systems mould are closed, and make stock and stamping systems film advanced in unison, position stock scribbling adhesive sticks material bed for the thermoprint of stamping systems film, makes that thermoprint is material bed to be transferred on the hot stamping pattern position of stock; This relief adhesive solidifies; After stamping systems film is stamped, stamping systems film becomes useless film, and useless film winder structure does not stop useless film to batch and rolling, and the sheet impressed release is completed hot stamping process process by the mechanism of paper of holding in the month of lining roller groove;
It is characterized in that, in above-mentioned steps (1), neutral gear length value before the every sheet of printing stock designed and thermoprint zone length numerical value are input to central controller;
In above-mentioned steps (2), the rotational angle of lining roller is constantly detected by angle measurement equipment, testing result is sent to central controller, the data message that central controller inputs according to angle measurement equipment measurement result and step (1), judges the turned position of front end, stock thermoprint region and rear end on lining roller;
When the front end, thermoprint region of stock on lining roller is through pressing point, roller platen is pushed to serve as a contrast roller, make roller platen and lining roll-in tightly, the normal impression described in enforcement; And in normal moulding process, drive the movable roll being positioned at the coating materials draw off gear of eindruckwerk upstream to move the stationary roll of close movable roll upstream and downstream, make the coating materials running orbit line length of eindruckwerk upstream shorten, coating materials draw off gear discharges coating materials; In normal moulding process, drive the movable roll being positioned at the useless film draw off gear in eindruckwerk downstream away from the stationary roll of movable roll upstream and downstream, the useless film running orbit line length in eindruckwerk downstream is extended, useless film draw off gear stores the useless film of a part; In normal moulding process, stamping systems film unreeling structure continues not park volume, useless film winder structure continues not suspend volume, and the length of coating materials draw off gear release coating materials adds that unreeling length equals to impress length, and the length that useless film draw off gear stores useless film adds that rolling length equals to impress length;
