The technical scheme of the utility model is as follows: comprises a printing plate and a scraper component, wherein the printing plate is a flat plate, the middle of a frame is provided with a plurality of spacing grooves, two sides of each spacing groove are respectively provided with a plurality of solder paste holes and positioning holes which are matched with the frame,
the both sides of printing plate still be equipped with respectively with the sand grip that the interval groove is parallel, the activity of scraper blade subassembly is in carry out the solder paste printing on the sand grip.
The scraper blade subassembly includes scraper seat and scraper blade, the scraper seat is the cuboid, the storage tank has been seted up to the bottom of scraper seat, the scraper blade is located in the storage tank.
And a fixing bolt penetrates through the middle of the scraper plate seat and penetrates through the top of the middle of the scraper plate to hinge the scraper plate in the accommodating groove.
The top of the scraper plate and the top of the containing groove are provided with a certain gap.
Adjusting bolts are further arranged on two sides of the top of the scraper plate seat in a penetrating mode downwards respectively, and the tail ends of the adjusting bolts extend into the containing groove and are located above two sides of the scraper plate.
The bottom of scraper blade still is equipped with two breachs respectively, the breach with the sand grip adaptation.
The utility model comprises a printing plate and a scraper component, wherein a plurality of spacing grooves are arranged on the printing plate, solder paste holes and positioning holes which are matched with a frame product are respectively arranged on two sides of each spacing groove, the spacing grooves are just matched with bulges in the frame product, the fixing and limiting effects on the frame during solder paste printing are achieved, and on the other hand, excessive spreading and interference of solder paste on two sides are prevented, so that the printing quality of the product is influenced. The scraper blade subassembly adopts the adjustable articulated mode to the scraper blade, through the adjusting bolt who adjusts both sides to both sides inclination's purpose when reaching regulation scraper blade printing can adapt to the uneven volume of paining of printing plate surface thickness finally, and then can make the gluey point volume in the tin cream inslot even.
