Abstract
The utility model relates to a stepless quantitative spray coating device for powder materials. The utility model is provided with a material storing pipe. The pipe wall of the material storing pipe is respectively provided with a material inlet, a material outlet and an air inlet. The material storing pipe is provided with a powder material blanking roller inside. The surface of the powder material blanking roller is in a rack shape. The outer side of the powder material blanking roller is respectively provided with a material scraping knife and a material baffling plate. The utility model can implement the stepless and quantitative adjustment of the spray coating quantity of powder to spray and coat evenly through adjusting the size of a gap between the material scraping knife and the powder material blanking roller and the speed of the powder material blanking roller. The utility model is suitable for spraying and coating resin powder with high water absorbability, etc.
Description
The utility model relates to powder and spills coating device.
Application number is 89200084.8 Chinese patent (notification number CN2044907U, name is called " apparatus for coating of fine particulate, powdered rubber ") a kind of powder coated device is provided, it comprises a rectangle hopper, is loaded on vibrator and a dispersion roller of being with mane on the hopper, rely on the effect of playing of mane, with particulate matter equably cloth be spread across and disperse to wait to be coated with on the plane below the roller, the paper surface etc. that can be used for operation continuously applies granular material.Owing to rely on vibrator vibration blanking, be difficult to quantitatively control effectively powder dropping amount, bigger vibration noise is arranged simultaneously.
This reality have novel purpose be to provide a kind of new structure powdered rubber spill coating device, can more accurately control powder and spill the amount of being coated with, the friction noise.
The utility model comprises storing pipe, blanking roller, and charging aperture and discharging opening are arranged on the storing tube wall, and air inlet is arranged on the storing tube wall in addition, the blanking roller is positioned within the storing roller, the surface of blanking roller becomes spline-simulating, a side device scraper cutter of blanking roller, opposite side device striker plate.
Further feature of the present utility model is that the blanking roller becomes eccentric position to install with the storing roller; The surface of blanking roller becomes the circle-arc tooth strip; The air inlet of storing pipe is connected with the air outlet of storage airduct, and the storage airduct is connected with blast pipe; Said scraper cutter passes the storing pipe.
After powder material enters the storing pipe from the hopper of charging aperture upside, the zone between striker plate and the scraper cutter is stayed in storage, when the blanking roller clockwise rotates, because an end of scraper cutter and the peak-to-peak gap of tooth on blanking roller surface are very little, most of powder is lived by scraper cutter shelves, the powder in the trench district between two teeth of blanking roller surface then can not stopped by the scraper cutter, when entering the discharging opening of storing pipe, falls to spilling to be coated onto and treats on the coated object.The air of heat drying enters the storage airduct by blast pipe in advance, enter the air inlet of storing pipe again, and flow out by discharging opening, to blanking roller bottom, the powder and the discharging opening that fall carry out heat drying, make powder not with blanking roller surface or discharging opening viscous, along with the running of blanking roller, powder spills continuously and is coated with.
Regulate rotating speed and the scraper cutter and the peak-to-peak gap length of blanking roller tooth of blanking roller, can realize that the stepless powder of regulating quantitatively spills the amount of being coated with.The utility model can more accurately be controlled powder and spill the amount of being coated with, and spills to be coated with evenly the friction noise.
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the utility model A-A is to cutaway view.
Fig. 3 is that the utility model B-B is to cutaway view.
Fig. 4 is the sectional view of blanking roller.
Further specify below in conjunction with accompanying drawing.
See Fig. 2, Fig. 3, (1) is the storing pipe among the figure, and charging aperture (15) is arranged on its tube wall, discharging opening (16), and charging aperture connects the powder funnel above (15), and following laying of discharging opening (15) waits to spill the material (as paper base, cloth material base etc.) that is coated with powder.Blanking roller (8) is positioned at storing pipe (1), and both can install with one heart, also can eccentricly install, and present embodiment is got eccentric installation position, and the blanking roll shaft heart departs from storing tubular axis heart X to 3 millimeters, and Y is to 3 millimeters.The Surface Machining of blanking roller (8) becomes spline-simulating, and Fig. 4 is seen in its cross section, and present embodiment is got arc rack, the part tooth bar face that only draws among the figure, 2.5 millimeters of arc radius.Blanking roller (8) one side device scraper cuttves (2), the peak-to-peak gap adjustment range of tooth on its end face and blanking roller (8) surface is the 40-100 silk.The opposite side device striker plate (14) of blanking roller (8) is made of the elastic stainless steel leather material, and the one end is fixed in frame, pass the charging aperture of storing pipe, the other end becomes sealing to flexibly connect with the blanking roller, for example relies on its elasticity, near the blanking roller, make powder directly not leak to discharging opening.See Fig. 2, storing pipe (1) closed at both ends is in ring piece (11), and blanking roller (8) two ends are by gasket ring (12) and storing pipe (1) closed at both ends, and so powder can not leak to two ends.See Fig. 2, Fig. 3, blast pipe (9) is connected with storage airduct (6), by air inlet (17) the dry air feeding storing pipe (1) of will sending out heating (50-100 ℃) in advance first, the bottom of heat drying blanking roller (8), discharging opening (16) and spill the powder that is coated with downwards, make powder not viscous pile up.The rotating speed of blanking roller can get 10 changes-150 rev/mins, decides according to spilling powder coating thickness.7 is neck bush among Fig. 2.
The utility model is coated with applicable to spilling of powder such as super absorbent resin.
Claims (5)
1. the stepless coating device that quantitatively spills of powder, comprise storing pipe (1), blanking roller (8), charging aperture (5) and discharging opening (16) are arranged on storing pipe (1) tube wall, it is characterized in that on storing pipe (1) tube wall air inlet (17) being arranged, blanking roller (8) is positioned within the storing pipe (1), and the surface of blanking roller (8) becomes spline-simulating, one side device scraper cutter (2) of blanking roller (8), opposite side device striker plate (14).
