Abstract
The utility model discloses a piston and air-blowing dual-feeding device for a scraper of an extrusion molding and mould pressing bottle cap machine. The piston and air-blowing dual-feeding device comprises a cylindrical main body, wherein the lower part of the cylindrical main body is provided with a semicircular scraper opening. The piston and air-blowing dual-feeding device is characterized in that a piston cavity is formed in the cylindrical main body; a piston is arranged in the piston cavity; a return spring is arranged on the outer wall of the piston; a middle hole is formed in the piston; an air inlet is formed in the wall of the cylindrical main body; the top of the piston cavity is provided with a sealing cover; the lower part of the sealing cover is in contact with the piston; and the sealing cover is fixed with the cylindrical main body through a clamping spring. The piston is pushed through air pressure, and hot melt plastics are pushed downwards for a short distance by the piston, so that the hot melt plastics and the scraper opening, which are adhered together, are loosened; and the hot melt plastics are blown by air pressure through the middle hole, so that the hot melt plastics rapidly drop into a die cavity, and the residual hot melt plastics are prevented from being adhered to the scraper opening. According to the piston and air-blowing dual-feeding device, the feeding is accurate, the blanking is complete, the high product percent of pass is guaranteed, the process of cleaning residual materials in shutdown is eliminated, and the working efficiency is improved.
Description
Technical field
The utility model relates to extrusion molding mold pressing bottle capper, particularly relates to the piston of extrusion molding mold pressing bottle capper scraper, the dual pay-off of blowing, and is mainly used in processing the plastic bottle closure of mineral water bottle and oil bottle, belongs to the plastics machinery field.
Background technology
In the equipment of the plastic bottle closures such as processing mineral water bottle and oil bottle, at first by extruding machine plastic raw materials is extruded, the plastic raw materials of extruding is sent into a fritter plastic raw materials in the mould of capping machine by doctor blade system, by compression molding, mostly described doctor blade system and capping machine are to finish in the rotation function separately, must work in coordination again, wherein doctor blade system mainly comprises turning cylinder, scrapes cutterhead and is arranged on the scraper of scraping on the cutterhead.Existing scraper has two kinds of patterns, a kind of is the sheet scraper, another kind is half-round scraper, described half-round scraper is divided into two sections, epimere is the cylinder of mesopore, hypomere is the semi-cylindrical shaped of opening, during work, when semicylindrical opening rotated to the extrusion of extruding machine, the scraping extrusion plastic was rotated further the die location of capping machine, at this moment blown facing to the cylinder mesopore by blowning installation, by the pressure of blowing the plastics in the semi-cylindrical shaped opening are blown off in mould, the feeding of this scraper exists following shortcoming: the one, and blanking speed is slow, because single dependence air blowing blanking, the plastics that are bonded on the opening come off slowly, produce easily displacement, it is inaccurate to feed intake, and causes product rejection; The 2nd, blanking is incomplete, and a small amount of plastics are bonded on the perforated wall of scraper, and the time one is long, and the plastics hardening can be tied more serious and more serious, shuts down clearly material, affects operating efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provides a kind of feeding accurate, and blanking is complete, improves piston, the dual pay-off of blowing of the extrusion molding mold pressing bottle capper scraper of product percent of pass.
The technical scheme of the piston of the utility model extrusion molding mold pressing bottle capper scraper, the dual pay-off of blowing is: comprise cylinder-shaped body, the bottom of cylinder-shaped body is the semicircular edge of a knife of scraping, it is characterized in that being shaped with plunger shaft in the described cylinder-shaped body, piston is set in the plunger shaft, piston outer wall is installed back-moving spring, described piston is shaped with mesopore, in the cylinder-shaped body wall, be shaped with air inlet, seal cover is installed at the plunger shaft top, contact with piston below the seal cover, seal cover fixes through jump ring and cylinder-shaped body.
The utility model discloses a kind of piston of extrusion molding mold pressing bottle capper scraper, the dual pay-off of blowing, during work, moved around turning cylinder by the moving scraper of scraper dribbling, when the half-round scraper mouth of scraper infraoral moves to the extrusion of extruding machine, scrape the heat that edge of a knife scraping extrudes and melt plastics, scraper continues to move to the die location of capping machine, pass into air pressure this moment from the air inlet of scraper sidewall, air pressure enters in the plunger shaft of cylinder-shaped body through air inlet, because the top of plunger shaft is fixing dead by seal cover and jump ring sealing, therefore air pressure can only push away piston downwards, the lower end of piston is melted heat plastics downwards and is promoted a bit of distance downwards, make heat melt plastics and to scrape the edge of a knife bonding no longer tight, and the upper end of piston owing to press down disengage seal cover below, air pressure is entered from the mesopore of piston, and blow out from the piston bottom, the air pressure that blows out melts heat rapidly plastics and blows off in the die cavity of capping machine, and the mould matched moulds melts plastics to heat and carries out compression molding.Piston, the dual pay-off of blowing of this programme extrusion molding mold pressing bottle capper scraper; at first by pushing away under the air pressure pushing piston; by piston heat is melted plastics and promote a bit of distance downwards; make heat melt plastics and to scrape the bonding generation of the edge of a knife loosening; blow heat by air pressure through mesopore again and melt plastics; heat is melted in the die cavity that plastics fall to rapidly mould; having avoided the part residual heat to melt plastics is bonded at and scrapes the edge of a knife; feeding is accurate; blanking is complete; guarantee product percent of pass, eliminated and shut down the operation of removing defective material, improved operating efficiency.
Piston, the dual pay-off of blowing of the utility model extrusion molding mold pressing bottle capper scraper, described seal cover outer wall is installed sealing ring, and sealing ring contacts with the inwall of cylinder-shaped body.The seal cover outer wall is installed sealing ring, improves the sealing of seal cover and cylinder-shaped body inwall.
