The utility model discloses a realize through following technical scheme:
a horizontal automatic sand feeding system for a sand mold 3d printing device comprises an air pump 1, a raw sand bin 4, a sand feeding groove 6, a sand discharging valve 5, a sand mixing device 9, a sand paving device 11 and a weighing sensor 7. The method is characterized in that in the sand mold printing process, when sand needs to be fed, the air pump 1 is opened, the raw sand in the raw sand bin 4 is conveyed to the upper sand tank 6 through air force, after weighing sensors 7 at two ends of the upper sand tank 6 are weighed, a sand discharge valve 5 below the upper sand tank is opened, the sand enters the sand mixing device 9, after a curing agent is added into the sand mixing device 9 to complete sand mixing, the sand enters an air conveying pipeline and is conveyed into a sand paving device 11 on sand mold printing equipment to be paved.
Furthermore, the sand feeding groove 6 is of a horizontal structure, and the bottom of the sand feeding groove is fixedly connected with the sand discharging valve 5. And weighing sensors 7 are fixed at two ends of the sand feeding groove 6, so that accurate sand feeding is realized.
Furthermore, the sand unloading valve 5 is also a horizontal flap valve, and the lower end of the sand unloading valve extends into the sand mixing device 9 and is not in contact with the sand mixing device 9 to play a guiding role.
Further, the sand mulling device 9 adopts a horizontal spiral belt type mixing structure, and plays a role in mulling sand and conveying sand particles. The sand mixing device 9 and the sand paving device 11 transmit sand through air force without direct contact.
Further, the whole system adopts positive pressure conveying, and the device is fixed in the sand mold printing equipment.
To sum up, the beneficial effects of the utility model are that: the accurate sand feeding is realized through the weighing sensors at the two ends of the sand feeding groove, and meanwhile, the sand feeding groove and the sand mixing device both adopt horizontal structures consistent with the sand paving device.
Drawings
The accompanying drawings, which form a part hereof, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention without undue limitation. In the drawings:
fig. 1 is a schematic view of a horizontal automatic sand feeding system of a sand mold 3d printing apparatus.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
The technical scheme of the utility model is explained in further detail below with the attached drawings:
as shown in figure 1, the horizontal automatic sand feeding system for the sand mold 3d printing equipment comprises an air pump 1, a raw sand bin 4, a sand feeding groove 6, a sand discharging valve 8, a sand mixing device 9, a sand paving device 11 and a weighing sensor 7. The method is characterized in that in the sand mold printing process, when sand needs to be fed, the air pump 1 is opened, the raw sand in the raw sand bin 4 is conveyed to the upper sand tank 6 through air force, after weighing sensors 7 at two ends of the upper sand tank 6 are weighed, a sand discharge valve 8 below the upper sand tank is opened, the sand enters the sand mixing device 9, after a curing agent is added into the sand mixing device 9 to complete sand mixing, the sand enters an air conveying pipeline and is conveyed into a sand paving device 11 on sand mold printing equipment to be paved.
The sand feeding groove 6 is of a horizontal structure, and the bottom of the sand feeding groove is fixedly connected with a sand discharging valve 8. And weighing sensors 7 are fixed at two ends of the sand feeding groove 6, so that accurate sand feeding is realized.
The sand unloading valve 8 is also a horizontal flap valve, the lower end of the sand unloading valve extends into the sand mixing device 9 and is not contacted with the sand mixing device 9, and the guiding effect is achieved.
The sand mulling device 9 adopts a horizontal spiral belt type mixing structure and simultaneously plays a role in mulling sand and conveying sand particles. The sand mixing device 9 and the sand paving device 11 transmit sand through air force without direct contact.
The whole system adopts positive pressure conveying, and the device is fixed inside the sand mold printing equipment.
