The utility model is characterized in that a three-way valve 1 is connected with an asphalt input pipe and a return pipe, and the other outlet of the three-way valve 1 is communicated with the middle upper part of a gun filling pipe 2 via a pipeline; driving gears 6, 7 and 10 are respectively arranged on the gun filling pipe 2, the three-way valve 1 and a chopping disc 5, the lower end of the gun filling pipe 2 is provided with a gun head 3, and a one-way valve 8 is used for controlling the air inlet of a blowing cavity 9. A tapered gun valve 4 is arranged at the lower end of the gun head 3, and the chopping disc is arranged at the lower side of the gun head 3.

Description

Electronic no wire drawing pitch can rifle

The utility model relates to electronic no wire drawing pitch can rifle, belongs to field of mechanical technique.

Existing pitch filling apparatus adopts the pitch flow in the manual shutoff valve control pitch pipeline, and mouth of pipe wire drawing phenomenon is serious, contaminated environment, and the can amount is difficult to accuracy control.

The purpose of this utility model is the deficiency that will overcome existing pitch filling apparatus, provides a kind of can not have wire drawing and pollutes, and the quick electric of plastic bag packaging does not have wire drawing pitch can rifle.

The purpose of this utility model is achieved in that electronic no wire drawing pitch can rifle is provided with triple valve 1, irritate gun barrel 2, rifle head 3, taper rifle valve 4, filament cutting dish 5, actuating device 6,7,10, check valve 8, air blowing cavity 9, triple valve 1 links to each other with the pitch counter flow pipe with the pitch input pipe, another valve port is connected by pitch pipeline and filling gun barrel 2 middle and upper parts, actuating device 7 is contained on the triple valve 1, irritate gun barrel 2 usefulness conduction oil or steam insulations, irritate gun barrel 2 and be provided with actuating device 6, be used to control the keying of taper rifle valve 4, irritate gun barrel 2 lower ends and be provided with rifle head 3, be provided with air blowing cavity 9 in the rifle head 3, the uniform aperture of cavity inner surface is provided with the air guiding wall from the horizontal by the oblique angle, air blowing cavity 9 links to each other with blowpipe, check valve 8 is loaded on the blowpipe, and taper rifle valve 4 is loaded on the lower end of rifle head 3, can be positive cone or anti-taper, cone-shaped sealing ring has tight fitting surface, filament cutting dish 5 is located under the rifle head, is a concave disks body structure, and front end is sharp-pointed, the middle part is a spill, and actuating device 10 is located on the filament cutting dish 5.

The utility model is rational in infrastructure, and the pitch can does not have wire drawing, and filling speed is fast, and can amount error is little, and is free from environmental pollution, has solved existing pitch filling apparatus and has used inconvenience, and problems such as waste and reduction asphalt quality have application value preferably.

Accompanying drawing 1 is a structural representation of the present utility model, 1 triple valve among the figure, 2 irritate gun barrel, 3 rifle heads, 4 taper rifle valves, 5 filament cutting dishes, 6,7,10 actuating devices, 8 check valves, 9 air blowing cavitys, triple valve 1 links to each other with the pitch counter flow pipe with the pitch input pipe, its another valve port is communicated with by pipeline with filling gun barrel middle and upper part, and actuating device 7 is contained on the triple valve 1, irritates gun barrel 2 usefulness conduction oil or steam insulations, irritate gun barrel 2 and be provided with actuating device 6, be used to control the keying of taper rifle valve 4, irritate gun barrel 2 bottoms and be provided with rifle head 3, be provided with air blowing cavity 9 in the rifle head 3, uniform 12 apertures of cavity inner surface, be provided with 30 ° air guiding wall, air blowing cavity 9 links to each other with blowpipe, and check valve 8 is loaded on the blowpipe, taper rifle valve 4 is loaded on the lower end of rifle head 3, tapering is 60 °-90 °, can be positive cone or anti-taper, and cone-shaped sealing ring has tight fitting surface, the sealing bandwidth is 5-10mm, filament cutting dish 5 is located under the rifle head, is a concave disks body structure, and front end is sharp-pointed, the middle part is a spill, and actuating device 10 is loaded on the filament cutting dish 5.Reach 110 °-120 ° pitch through heating, send into triple valve 1 with pump or gravity tank, after packaging bag enters filling position, actuating device 6 is opened taper rifle valve 4, actuating device 7 is opened triple valve 1 subsequently, when can weight reaches scheduled volume 90%, actuating device 7 cuts out triple valve 1, the residue pitch of irritating in the gun barrel 2 continues can, when weighing reached predetermined can amount, actuating device 6 quick closedown taper rifle valves 4 were after control circuit obtains taper rifle valve 4 closing signals, open check valve 8 rapidly, pressurized air enters air blowing cavity 9, laterally blows the wire drawing pitch of disconnected rifle head, and actuating device 10 drives filament cutting dish 5 and cuts off the residual bitumen silk at a high speed, automatically remove the good packaging bag of can by belt conveyor, send into empty bag to filling position.
