Detailed description of the invention
Referring to Fig. 1, the better embodiment of this utility model powder feeder unit includes that supporting part 10, support member 200 and supplies powder car 20.In present embodiment, this supporting part 10 can be the wall of forming bin in a 3D printer, is provided with a shaping area 800 in the forming bin of this 3D printer.
Arranging a guide portion 100 on this supporting part 10, this guide portion 100 includes a desired guiding trajectory.In present embodiment, this desired guiding trajectory is a track being parallel to this shaping area 800.This confession powder car 20 is connected to the first end of this support member 200, and the second end of this support member 200 is slidably arranged in this guide portion 100, so that this confession powder car 20 can move along this desired guiding trajectory, as controlled this confession powder car 20 linearly operating along this track place.In other embodiments, this can also be other track for the track that powder car 20 runs, such as a circular or sector, as done cycling action with certain point for initial point by controlling this confession powder car 20.
This confession powder car 20 includes a receiving space 209, be arranged in this receiving space 209 Powder spreader 30, two scraper 50 and two roller bearings 40.In present embodiment, this receiving space 209 is substantially in cuboid, and it is provided with two relative openings in Z-direction, and this receiving space 209 is made up of the two sides along a first direction (X-axis) and the two sides 290 along a second direction (Y-axis).In present embodiment, along the two sides of Y direction, it is respectively equipped with a pair first installing holes 205 and a pair second installing holes 203.
Seeing also Fig. 2 and Fig. 3, this Powder spreader 30 includes that one is arranged at the powder feeder 305 in this confession powder room 321 by what some sidewalls 300 formed for powder room 321 and a rotation.This powder feeder 305 contacts with the sidewall 300 of this confession powder room 321, to form the load chamber 331 for loading powder to be formed.This powder feeder 305 includes the contact surface 307 of a powder 70 to be formed contact, if being provided with dry-laid powder mouth 309 on this contact surface 307, can store some powder to be formed 70 in paving powder mouth 309.When this powder feeder 305 rotates, when a paving powder mouth 309 on the contact surface 307 of this powder feeder 305 is turned to a second position by a primary importance, the powder to be formed 70 in paving powder mouth 309 on this contact surface 307 can drop down onto in this shaping area 800, and then reaches to spread the purpose of powder.
In present embodiment, this confession powder room 321 includes the two side 300 being oppositely arranged, and as this two side 300 can be arranged along X-direction, two side 300 is connected with the two sides 290 arranged along Y-axis, is thusly-formed this confession powder room 321.This powder feeder 305 is generally cylindrical, and the two side ends of this powder feeder 305 is respectively arranged with one first projection 301, and this first projection 301 is pivotally mounted in this first installing hole 205.The outer surface of this powder feeder 305 forms this contact surface 307, and this contact surface 307 contacts with two side 300 respectively, and the two sides 290 that the two side ends of this powder feeder 305 is arranged with Y-axis the most respectively contact, to form this confession powder room 321.In present embodiment, this powder feeder 305 can be driven by an actuating device.In other embodiments, this Powder spreader 30 also can be made up of four sidewalls, and four sidewalls form this confession powder room 321, and the sidewall of the two side ends of this powder feeder 305 correspondence the most respectively contacts.
In present embodiment, at least one scraper 50 is also set up in the receiving space 209 of this confession powder car 20, this scraper 50 has and extends the one of this receiving space 209 and scrape powder portion 340, and this scrapes powder portion 340 for carrying out striking off process at the powder to be formed fallen into shaping area 800 from paving powder mouth 309.
In present embodiment, being additionally provided with two roller bearings 40 in the receiving space 209 of this confession powder car 20, the two side ends of this roller bearing 40 is respectively equipped with one second projection 401, and this second projection 401 rotates and is installed in this second installing hole 203.This confession powder car 20 also includes a motor 90, this motor 90 controls this roller bearing 40 and rotates, to carry out the powder to be formed on this shaping area 800 when this confession powder car 20 moves flattening operation, wherein this motor 90 also can control pressure when this roller bearing 40 contacts with this shaping area 800, so that 3D printer can be to the printing of different types of powder to be formed.In other embodiments, this motor 90 also can omit, and so when this confession powder car 20 moves, the powder to be formed on this shaping area 800 is carried out flattening operation under the drive of this confession powder car 20 by this roller bearing 40.
Refer to Fig. 4, when this desired guiding trajectory is a straight line, the density of paving powder mouth 309 centrally located on this contact surface 307 is more than the paving powder mouth 309 being positioned at two side positions, so when carrying out spreading powder operation, owing to mainly the powder to be formed 70 in this shaping area 800 zone line being printed when printing, too much powder to be formed so can be avoided to be laid on the periphery of this shaping area 800, advantageously reduce the waste of powder to be formed.
Referring to Fig. 5, when this desired guiding trajectory is circular, the density of this contact surface 307 upper berth powder mouth 309 is proportional with the distance in paving powder mouth 309 to the center of circle, i.e. in time running the density of paving powder mouth 309 close to the center of circle less than the density spreading powder mouth 309 away from the center of circle.Due to when this confession powder car 20 does circumference or fan-shaped operation, on this powder feeder 305, the speed of service of each paving powder mouth 309 differs, so for making to spread powder more uniformly, the density of the paving powder mouth 309 that paving powder mouth 309 density on the contact surface 307 that the speed of service is slow is less than on the contact surface 307 that the speed of service is fast.In present embodiment, the density of this paving powder mouth 309 can be determined by the quantity spreading powder mouth 309 in unit are.In present embodiment, the shape of this paving powder mouth 309 can be, include but not limited to, one is circular or one square.
In present embodiment, the sidewall 300 of this Powder spreader 30 being additionally provided with some sensors 311, these sensors 311 capacity of powder 70 to be formed in detecting this load chamber 331, to send information warning when powder 70 to be formed is not enough.
In present embodiment, two scrapers 50 of this confession powder car 20 are arranged at the both sides of this Powder spreader 30, and two roller bearings 40 of this confession powder car 20 are respectively arranged at away from scraper 50 in the side of this Powder spreader 30 relatively.
If above-mentioned powder feeder unit is by being provided with dry-laid powder mouth 309 on contact surface 307, so that the powder to be formed in paving powder mouth 309 is relatively evenly dropped down onto in this shaping area 800 when the primary importance of this powder feeder 305 turns to the second position, so can avoid spreading too much powder and can cause the waste of powder to be formed, improve the utilization rate of powder to be formed.
Those skilled in the art will be appreciated that; above embodiment is intended merely to this utility model is described; and it is not used as to restriction of the present utility model; as long as within spirit of the present utility model, made above example suitably change and change all to fall is asked within the scope of protection at this utility model.
