Abstract
The utility model provides a scraper assembly for an air-cooling pelletizer, which fulfills the buffering function when a scraper pushes against the extruding end of a mould head and prolongs the service life of the scraper. The scraper assembly for the air cooling pelletizer comprises a scraper base and the scraper arranged on the scraper base and is characterized in that the scraper assembly also comprises a connecting shaft, a pressing nut and a pressing spring, wherein the scraper base is sleeved on the connecting shaft; one end of the connecting shaft is linked with the output end of an external motor; the other end of the connecting shaft and the scraper base form axial limitation matching; the connecting shaft is provided with an external thread; the pressing nut is sleeved on the connecting shaft; one end of the pressing spring is butted to the connecting nut; and the other end of the pressing spring is butted to the scraper base. The scraper base is avoided detaching from the connecting shaft by a clamping block, and the function of the pressing spring is to enable the scraper base and the clamping block to tightly press mutually; when the scraper rotates and pushes against the extruding end of the mould head, the scraper moves in an opposite direction if the pressure is larger than the elasticity function of the pressing spring, therefore, the scraping force of the scraper applied on the extruding end of the mould head during rotation is reduced, and the service lives of the scraper and the mould head are prolonged.
Description
Technical field
The utility model relates to a kind of air-cooled comminutor doctor assemblies.
Background technology
Comminutor is a kind of forming machine that material can be manufactured given shape, is widely used in fields such as chemical industry, petrochemical industry, pharmacy, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, pottery, rubber, plastics.Air-cooled comminutor operation principle is; the die head extruding end is the plane; this extruding end is provided with a plurality of extrusion cavities; extruder is extruded material on the die head extruding end; the tool rest of scraping that the rotating shaft of motor output end is rotated and drive is installed in rotating shaft rotates then, scrapes tool rest and is provided with scraper, moves axially motor and scraper is pressed on the die head extruding end along rotating shaft; behind the scraper rotary scraping and brushing, on the die head extruding end, form the product of required form.But, owing to the power and the bad control that scraper are pressed on the die head extruding end,, then may cause the situation that scraper damages by pressure or die head scratches to occur if firmly excessive, extremely it is unfavorable for production cost and production efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and has had cushioning effect when scraper is pressed on the die head extruding end, and improves the scraper air-cooled comminutor doctor assemblies in service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of air-cooled comminutor doctor assemblies; include and scrape tool rest and install in the scraper of scraping on the tool rest; it is characterized in that: also include connecting axle, clamp nut and holddown spring; described scraper cover for seat is located on the connecting axle; one end of connecting axle and the interlock of external motor output; the other end with scrape tool rest and constitute axial limiting and cooperate; connecting axle is provided with external screw thread; clamp nut is sheathed on the connecting axle; one end and the attaching nut of holddown spring are inconsistent, and the other end is with to scrape tool rest inconsistent.
Of the present utility modelly further be set to: the described tool rest of scraping is provided with and the suitable through hole of connecting axle external diameter, the scraper cover for seat is located on the connecting axle and is constituted slippage with connecting axle and cooperates, connecting axle upper blade seat is provided with fixture block with respect to the opposite side of clamp nut place side, and the fixture block minimum diameter is greater than scraping through hole internal diameter on the tool rest.
Adopt technique scheme, scraping tool rest installs on connecting axle and can slide along connecting axle, fixture block on the connecting axle is to scraping tool rest spacing on having played axially, having avoided scraping tool rest deviates from from connecting axle, and the effect of holddown spring is to make to scrape tool rest and fixture block compresses mutually, thereby realize when the pressing on the die head extruding end of scraper rotation, scrape when tool rest is subjected to pressure from scraper less than the holddown spring elastic force and be not moved; If pressure will oppositely move during greater than the holddown spring resilient force, so when reducing the scraper rotation to the wiper power of die head extruding end, the service life of improving scraper and die head.
Of the present utility modelly further be set to: the described tool rest of scraping is discoid again, through hole is opened in the center of scraping tool rest, scrape that the opposite side with respect to clamp nut place side extends outward three symmetrically arranged extending seats on the tool rest, scraper is installed on extending seat respectively.
Adopt technique scheme, scrape tool rest and be provided with three scrapers, the operating efficiency of scraper when having improved doctor assemblies work, product is stable when also having guaranteed scraper work.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, present embodiment includes scrapes tool rest 1, install in the scraper of scraping on the tool rest 12, connecting axle 3, and be sheathed on clamp nut 4 and holddown spring 5 on the connecting axle 3, scrape tool rest 1 for discoid, scrape tool rest 1 center and offer a through hole, scraping tool rest 1 is sheathed on the connecting axle 3, connecting axle 3 includes and is positioned at interlock end 31 and the screens end 32 of scraping tool rest 1 both sides, connecting axle 3 first line of a couplet moved ends 31 and motor output end be linkage fixedly, screens end 32 ends are provided with the fixture block 321 of annular, the external diameter of fixture block 321 is greater than the internal diameter of through hole, connecting axle 3 interlock ends 31 places are provided with external screw thread, clamp nut 4 is threaded with the external screw thread formation, one end and the clamp nut 4 of holddown spring 5 are inconsistent, and the other end is with to scrape tool rest 1 inconsistent.Wherein, scrape that the opposite side with respect to clamp nut 4 place sides extends outward three symmetrically arranged extending seats on the tool rest 1, scraper 2 is installed respectively on extending seat 11.Scrape tool rest 1 and be provided with three scrapers 2, the operating efficiency of scraper 2 when having improved doctor assemblies work, product is stable when also having guaranteed scraper 2 work.
In the utility model, scrape that tool rest 1 is installed on connecting axle 3 and can slide along connecting axle 3,321 pairs of fixture blocks on the connecting axle 3 are scraped tool rest 1 spacing on having played axially, having avoided scraping tool rest 1 deviates from from connecting axle 3, and the effect of holddown spring 5 is to make to scrape tool rest 1 and fixture block 321 compresses mutually, thereby realize when the pressing on the die head extruding end of scraper 2 rotations, scrape when tool rest 1 is subjected to pressure from scraper 2 less than holddown spring 5 elastic forces and be not moved; If pressure will oppositely move during greater than holddown spring 5 resilient force, so when reducing scraper 2 rotations to the wiper power of die head extruding end, the service life of improving scraper 2 and die head.The utility model can also have other embodiments, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
