Abstract
The utility model relates to a secondary scraper of a continuous extruder, mainly comprising an extrusion wheel and a primary scraper; the extrusion wheel is arranged on the extruder; the primary scraper is horizontally arranged on the body of the extruder on the feeding end of the extrusion wheel; the primary scraper head is arranged in a wheel groove on the outer ring of the extrusion wheel and keeps an interval with the inner wall of the wheel groove; an end face of the primary scraper body keeps an interval with the face of the extrusion wheel; a secondary scraper on top of the primary scraper is arranged on the body of the extruder on the feeding end of the extrusion wheel; the secondary scraper head is arranged in the wheel groove on the outer ring of the extrusion wheel and keeps an interval with the inner wall of the wheel groove; and the end face of the secondary scraper body keeps an interval with the face of the extrusion wheel. The utility model is additionally provided with the secondary scraper on the basis of the conventional primary scraper, performs a sufficient scraping to the residual flash overflow after primary scraping, has simple and compact integrated structure, completely scrapes flash overflow on the extrusion wheel without frequent replacement and maintenance of the secondary scraper, reduces the production cost and meets the requirement of continuous and safe extrusion production; the extruded product has high quality.
Description
Technical field
The utility model relates to a kind of scraper of continuous extruder, is a kind of continuous extruder strikes off the extruding flash with secondary device specifically.
Background technology
Extruder is to utilize squeegee roller to be rotated by driven by motor, the bar base enters the squeegee roller race, because the frictional force effect of cell wall is drawn in the arc extrusion chamber that is formed by squeegee roller and cavity, under high pressure and high temperature action that frictional force produces, metal is extruded by die orifice and is formed tubing or section bar product, but have the gap between race and arc extrusion chamber, extrusion process unavoidably forms flash, must adopt scraper that the flash in the squeegee roller race is struck off.Problems such as existing extruder mostly adopts a scraper that flash is struck off, and it is insufficient to exist flash to strike off, and extruded product is of poor quality, a scraper use is easy to wear, and scraper must often be changed, maintenance, causes production capacity decline, and production cost increases.
Summary of the invention
Strike off insufficient for the squeegee roller that solves extruder in the prior art once strikes off flash, extruded product is of poor quality, one time scraper is fragile, the high deficiency of production cost, the purpose of this utility model provides that a kind of to strike off flash abundant, the extruded product quality is good, and scraper need not often be changed, keep in repair, the secondary scraper of the continuous extruder that production cost is low.
The technical solution adopted in the utility model: a kind of secondary scraper of continuous extruder, mainly comprise squeegee roller and a scraper, squeegee roller is arranged on the extruder, level is provided with scraper one time on the extruder fuselage of squeegee roller feed end, scraper is by a scraper blade and once scrape jet blade and form, once scraping jet blade places in the race of squeegee roller outer ring and is gap state with the race inwall, scraper blade end face and squeegee roller wheel face are gap state, its technical characterstic is also to be provided with the secondary scraper on the extruder fuselage of described squeegee roller feed end, the secondary scraper is arranged at the scraper top one time, secondary is scraped jet blade and is placed in the race of squeegee roller outer ring and be gap state with the race inwall, and secondary scraper blade end face and squeegee roller wheel face are gap state.
Further, a described scraper is fixed on the extruder fuselage through a scraper support level, once scrapes knife support and connects secondary through vertical link supports and scrape knife support, and secondary scrapes that horizontal fixed has the secondary scraper on the knife support.
Again further, a described scraper and secondary scraper spacing are the 4%-7% of squeegee roller diameter.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: one time scraper is arranged on the horizontal plane at squeegee roller center, once scraping jet blade places in the race of squeegee roller outer ring and is gap state with the race inwall, scraper blade end face and squeegee roller wheel face are gap state, extruder when work wheel face formation flash squeegee roller outside, the blade end face that scraper is provided with cutter head strikes off the flash of the outer wheel face of squeegee roller, flash can't a scraped clean, by the secondary scraper of scraper top the outer wheel face residue of squeegee roller flash being carried out secondary again strikes off, it is abundant to strike off flash, helps improving the extruded product quality; When scraper uses, even if a blade wears also can be replaced striking off flash by the secondary scraper, need not shut down replacing in process of production, safeguard, improved production efficiency, reduced production cost.
The utility model is set up the secondary scraper on the basis of former once scraper, fully strike off once striking off the residual flash in back, overall structure is simple, compact, can strike off the flash on the squeegee roller fully, the extruded product quality is good, the secondary scraper need not often be changed, safeguard, reduces production costs, and satisfies continuously, pushes safely and produce.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: squeegee roller 1, race 11, fuselage 2 is once scraped 41, scrapers of 4, scraper blades of 3, scrapers of knife support and is scraped 42, vertical connecting rod 5, secondary is scraped knife support 6, secondary scraper 7, secondary scraper blade 71, secondary is scraped jet blade 72.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Fig. 1,2, the secondary scraper of continuous extruder mainly comprises squeegee roller 1, a scraper 4 and a secondary scraper 7.Squeegee roller 1 is arranged on the extruder fuselage 2, level is provided with and once scrapes knife support 3 on the extruder fuselage 2 of squeegee roller 1 feed end, one time scraper 4 is horizontally fixed on the extruder fuselage 2 through once scraping knife support 3, one time scraper 4 is arranged on the horizontal plane at squeegee roller 1 center, scraper 4 is by a scraper blade 41 and once scrape jet blade 42 and form, once scrape in the race 11 that jet blade 42 places squeegee roller 1 outer ring and be gap state, be provided with scraper blade 41 end face and squeegee roller 1 wheel face of once scraping jet blade 42 and be gap state with the race inwall; Once scraping knife support 3 tops has secondary to scrape knife support 6 through vertical connecting rod 5 support and connection, secondary scrapes that horizontal fixed has secondary scraper 7 on the knife support 6, secondary scraper 7 is scraped jet blade 72 by secondary scraper blade 71 and secondary and is formed, secondary is scraped in the race 11 that jet blade 72 places squeegee roller 1 outer ring and is gap state with the race inwall, is provided with secondary and scrapes secondary scraper blade 71 end faces and squeegee roller 1 wheel face of jet blade 72 and be gap state; One time scraper 4 is the 4%-7% of squeegee roller 1 diameter with secondary scraper 7 spacings.
Extruder when work wheel face formation flash squeegee roller outside, be provided with the flash that a scraper blade end face once scraping jet blade strikes off the outer wheel face of squeegee roller, flash can't a scraped clean, secondary scraper by a scraper top strikes off the outer wheel face residue of squeegee roller flash again, and it is abundant to strike off flash.
