Blanking device is equipped with, the blanking device is connected with feeding warehouse, and the blanking device section is funnel-form and bottom and operation
Blanking portion is provided between platform, powder strickle, the laying device are provided with the blanking device on blanking portion top
It is arranged on mobile support, the operating platform bottom is provided with lowering or hoisting gear.
Further, vacuum suction feed arrangement and material position inductor, the material position sense are provided with the blanking device
Answer the opening and closing of device control vacuum suction feed arrangement.
Further, the powder strickle includes scraper plate and push-rod electric machine, the scraper plate bottom and laying device bottom
Provided with trimming part.
Further, it is provided with recovery approach between the inwall of the operating platform surrounding outer wall and recovery bin.
Further, connected between the blanking device and feeding warehouse by flexible pipe.
The beneficial effects of the invention are as follows:
The present apparatus is designed using twin pressure roller, and guarantee two pressure roller intermediate feeds, can be scraped with cyclic stone by powder
Flat device ensures the lift height of stone, the control and recovery of unnecessary powder.Device eliminates traditional discharging bin, corresponding increase
Area of work, reduce the backlash of roller stone.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
The embodiment of the present invention is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Technical scheme in technology in order to illustrate the embodiments of the present invention more clearly, in being described below to embodiment technology
The required accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present invention
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the laying device partial elevational structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Shown in reference picture 1 and Fig. 2, a kind of double rollers feed mechanism, including operating platform 1, operating platform are arranged on recovery
In storehouse 2, operating platform surface is provided with laying device 3, and laying device includes two pressure rollers 31 be arrangeding in parallel, two pressure rollers it
Between be provided with blanking device 32, blanking device is connected with feeding warehouse 4, and blanking device section is that funnel-form and bottom and operation are flat
Blanking portion 321 is provided between platform, powder strickle 5 is provided with the blanking device on blanking portion top, blanking portion is used for blanking
Device blanking, when laying depth is big, and blanking portion can not meet to require, the position that can be adjusted in blanking device vertical direction is come
Expand blanking portion, be adapted to coarse adjustment, laying device is arranged on mobile support 6, and operating platform bottom is provided with lowering or hoisting gear 7.
Wherein, vacuum suction feed arrangement 322 and material position inductor 323, material position inductor control are provided with blanking device
The opening and closing of vacuum suction feed arrangement processed, ensure when powder strickle operates, powder will not continue to blanking, ensure powder
Last uniformly vacuum suction feed arrangement can realize quick feeding, improve stone speed.
Powder strickle includes scraper plate 51 and push-rod electric machine 52, and scraper plate bottom is provided with trimming part 53 with laying device bottom,
Trimming part can adjust the position in scraper plate vertical direction according to the requirement of laying depth, overall to change small, suitable accurate adjustment, push rod
Motor pushing scraper plate moves along blanking device direction, and the push rod of push-rod electric machine be arranged in parallel with operating platform, ensures powder
After being struck off by scraper plate, the powder thickness struck off is uniform, ensures print quality.
Recovery approach 21 is provided between operating platform surrounding outer wall and the inwall of recovery bin, can reclaim unnecessary powder
End, set location and setting direction to powder strickle do not require that assembling is simple.

During original state, laying device is located on the left of operating platform, and vacuum suction feed arrangement is by the powder in feeding warehouse
Blanking in blanking device is adsorbed to, material position sensing control inlet amount is (when inlet amount exceedes theory demands, material position sensing control vacuum
Absorption feed arrangement is stopped, and ensures that powder does not fall), then powder strickle secondary-confirmation layer thickness, by unnecessary powder
End is scraped in recovery approach, realizes that recovery and powder thickness are uniform, is then moved support movement, is moved to down with laying device
One operating position, in movement, the pressure roller in left side flattens the powder laid, uses, is treated from left to right for subsequent operation
After being fully completed laying, without being reset to original state, the pressure on right side now can be then used directly from right side stone to the left
Roller flattens the powder laid.So mechanism conveniently reclaims excessive powder, and operating efficiency is high, and stone precision is high, energy
Improve print quality.
