The blanking agitating device
The utility model relates to a kind of blanking agitating device, belongs to technical field of plastic.
In the production process of plastic sheetings such as polyester, nylon or sheet material, can produce leftover pieces unavoidably, but polyester, nylon etc. belong to thermoplastic, recyclable utilization reduces production costs.General recovery technology be with film or sheet material after pulverizer is pulverized, blow to loading hopper by low-pressure air, send into granulating system extruding pelletizations such as twin-screw again from loading hopper, be used for using next time.But because differences such as shape, coefficient of frictions, can be caused not " the bridge formation ＂ phenomenon of blanking freely or not of blanking at loading hopper by the film after pulverizing or sheet material.For solving these phenomenons, normally on loading hopper, adorn vibrating device, strike towards material is fallen by vibration.But this kind structure generally is suitable for heavier particulate material.And for flaky material, because out-of-shape, weight is lighter, can produce hydro-planing behind the vibration percussion, also can cause the not smooth phenomenon of blanking.For this reason, in loading hopper, increased agitating device, made material constantly change down position by two stirring vanes up and down that are installed on the driving shaft, to reach anti-purpose of building bridge.Equally, because stirring vane is comprehensive in loading hopper material to be stirred, the also flaky material of inapplicable lighter weight.
Summary of the invention
The purpose of this utility model provides a kind of simple for structure, can prevent the blanking agitating device that sheet material is built bridge.
The utility model is that the technical scheme that achieves the above object is: a kind of blanking agitating device, comprise collecting bin, motor, decelerator, shaft and stirring vane, it is characterized in that: described shaft is installed in the bottom of collecting bin by bearing, shaft is connected with decelerator, described stirring vane is installed in the top of shaft, stirring vane is made of with the triangle scraper plate that is fixed on base plate top the base plate of strip-like-shaped, the middle and upper part that base plate is positioned at pusher one side has the cambered surface of indent, and distance is at 10～30mm between the base plate bottom surface of stirring vane and the collecting bin base plate.
The utility model is provided with a stirring vane in the bottom of collecting bin, and stirring vane adopts the base plate of strip, the sheet material of bottom can be discharged from the discharging opening of collecting bin bottom, especially the base plate middle and upper part that is positioned at pusher one side has the cambered surface of indent, can make on the sheet material to push away, the triangle scraper plate on the stirring vane also promotes sheet simultaneously, makes sheet material redistribute dispersion when descending, reach anti-purpose of building bridge, guarantee that blanking is unimpeded.The utility model adopts stirring vane simple in structure, and is not only easy to process, and is positioned at the bottom of collecting bin, do not influence sheet material and enters in the collecting bin, and sheet material is delivered in the cylindrical shell smoothly.

The specific embodiment
See shown in Figure 1ly, blanking agitating device of the present utility model comprises collecting bin 1, motor 7 decelerators 6, shaft 2 and stirring vane 4.See shown in Figure 1ly, collecting bin of the present utility model 1 top has charging aperture 11 and air outlet 12, by wind-force sheet material is sent in the collecting bin 1, and sheet material descends under the gravity effect, and wind enters in the exhaust duct by air outlet 12.This shaft 2 is installed in the bottom of collecting bin 1 by bearing; shaft 2 is connected with decelerator 6; decelerator 6 is connected with motor 7; motor 7 reaches shaft 2 with power after decelerator 6 slows down; stirring vane 4 is installed in the top of shaft 2; for ease of installation and maintenance; see Fig. 1; shown in 2; be welded with axle sleeve 43 at the middle part of stirring vane 4; stirring vane 4 is sleeved on the shaft 2; and it is spacing by the shaft shoulder of shaft 2; fixing with nut 3 again; stirring vane 4 is made of the base plate 41 of strip-like-shaped and the triangle scraper plate 42 that is fixed on base plate 41 tops, sees shown in Figure 3ly, and the middle and upper part that base plate 41 is positioned at pusher one side has the cambered surface 44 of indent; these triangle scraper plate 42 width are less than base plate 41 width; base plate 41 promotes material and falls in the feed pipe 5 of bottom from the discharging opening 13 of collecting bin 1 bottom in rotary course, deliver to by the screw propulsion blade in the heater of comminutor, and distance is at 10～30mm between base plate 41 bottom surfaces of stirring vane 4 and collecting bin 1 bottom surface.
