Abstract
The utility model belongs to the utility model of a blowing handpiece for manufacturing automatic sealing plastic film bags, comprising an outer mold body, an inner mold body, an inner formwork, an outer mold ring, mold opening regulating screws, a feed inlet, an air charging port, and an air outlet. The utility model is characterized in that the side face of the inner mold body is provided with a spiral discharge chute; the film outlet port contiguous to the side of the inner formwork is provided with a concave rib forming orifice and a convex rib forming orifice; the forming orifices of the concave and the convex ribs can be also provided with the thick and thin regulating screws. The utility model has the advantages of simple structure, low cost, convenient operation, high productivity, and high forming quality of the concave and convex ribs.
Description
The utility model relates to the manufacturing and processing equipment of plastic sheeting, belongs to the improvement invention of the blown-film die of making the self-sealing plastic film bag.
The self-sealing plastic film bag be on film mouth limit up and down correspondence set convex tendon bar and concave bar bar, cooperate by convex tendon bar and concave bar bar that embedding is self-styled mutually.The existing external import production equipment of making the self-sealing plastic film bag, die head adopt cross formula structure, and when making concave bar, convex tendon, thickness can not be regulated, the concave bar opening is undesirable, and thickness is thin uneven, easily causes waste of material, and the complete machine structure more complicated, operation requires high, and production efficiency is low.
The purpose of this utility model is in order to improve concave, convex rib opening quality and to simplify die head, reduce production costs, and a kind of blown-film die of spiral valve bag is provided.
Further purpose of the present utility model provides a kind of blown-film die that can regulate the spiral valve bag of concave, convex rib thickness.
The purpose of this utility model is finished by following technical scheme, be provided with the interior die body of cylindricality in the outer die body of a cylindrical shell shape, be provided with the feeding gap between outer die body and interior die body, should be provided with inner formword by interior die body, should be provided with outer die ring by outer die body, be provided with the gap as film outlet port between this inner formword and the outer die ring, and die body is provided with film mouth adjustment screw outside, position, die body following side is connected with described outer die body in described, establish charging aperture below, air-filled pore is established in the side, lead to gas outlet on this air-filled pore and the interior die body centre, described internal mold body side surface is provided with spiral groove, and lead to through hole and described charging aperture, be provided with concave bar bar shaped hole and convex tendon bar shaped hole at the adjacent film outlet port of the avris place of inner formword, and in described the also corresponding through hole that is provided with on the die body, also corresponding matching is provided with open slot on described outer die ring, also is provided with the dashpot circle in the porch of through hole.
Concave bar bar shaped hole on the above-mentioned inner formword and convex tendon bar shaped hole place are provided with the thickness adjustment screw.
Each can establish two above-mentioned inner formword fovea superior rib shaped hole and convex tendon bar shaped hole, and the open slot on the corresponding outer die ring also can be established two.
The course of work of the present utility model: plastics are come in from charging aperture, and following comes out thin hole from spiral groove in interior die body, in the gap of die body and outer die body, comes out middle air blowing film forming from the film outlet port drawing in clamp-oning.Simultaneously, concave bar bar shaped hole and convex tendon bar shaped hole are also extruded rib separately, with the film cementing be one together, because of concave bar bar and convex tendon bar through certain cooling shaping and film cementing, so shape is more accurate, quality is good.The film at cementing position cools off because of being subjected to the open slot air on the outer die ring, and film is contracted and partial thickening, thereby the film at concave, convex rib position is thickened, and improves intensity.Concrete operations situation Field adjustment.Blow the film after drawing, become bag through Bag Making Machine.
The utility model adopts the spirality chute feeder; on inner formword, offer concave bar bar and convex tendon bar shaped hole; offer open slot on the die body outside; only need on general blow molding machine, to improve; simple in structure, cost is low; easy to operate, and concave bar bar and convex tendon bar shaped hole establish adjustment screw, can regulate the shaping thickness.Therefore, the utlity model has simple in structure, cost is low, easy to operate, productivity ratio is high, concavo-convex rib forming quality advantage of higher.
