Description

Technical Field

[0001] The utility model relates to the technical field of 3D printed dentures, and in particular refers to a screening device for denture 3D printing materials. Background Art

[0002] In the process of 3D printing dentures, resin or metal can be used as raw materials for 3D printing of dentures. When using metal raw materials, metal powder with finer and more uniform particle size is required, otherwise it will affect the quality and precision of the finished denture. At present, when using a screening device to screen the metal powder, the metal powder with the particle size that meets the requirements will pass through the screen and fall, while the metal powder with a particle size larger than the screen aperture will remain above the screen. After the screening is completed, the metal powder that does not meet the requirements above the screen needs to be cleaned and collected in a centralized manner. The current screening device is not convenient for repeatedly cleaning and collecting the metal powder remaining on the screen. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] The technical problem to be solved by the utility model is that when a screening device is currently used to screen metal powder, metal powder with larger particle size is left on the screen, which will affect the subsequent screening process, and it is inconvenient to repeatedly clean and centrally recover the metal powder left on the screen.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a screening device for denture 3D printing materials, comprising a screening structure and a base plate, the upper end of the base plate is fixedly connected with relatively arranged short columns and high columns, the screening structure comprises springs arranged at the upper ends of the short columns and high columns, the upper ends of the springs are provided with side plates, a sieve bucket is fixedly connected between the side plates arranged relatively on both sides, a sieve net is provided in the sieve bucket, the sieve bucket is in an inclined state, the upper end of the base plate is provided with a collecting box cooperating with the sieve net and a concentrating box cooperating with one end of the sieve bucket, and a vibration motor is provided on the sieve bucket.

[0007] As an improvement, a handle is fixedly connected to the collection box.

[0008] As an improvement, one end of the screen bucket is fixedly connected with an extension plate that cooperates with the central box.

[0009] As an improvement, the collection box and the concentration box are placed on the upper end of the base.

[0010] As an improvement, the screen bucket is provided with an adjustment knob electrically connected to the vibration motor.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model has the following advantages: metal powder is put onto the guide screen, and the vibration motor is used to drive the screen bucket to vibrate. With the cooperation of the spring, the inclined screen bucket and the screen will vibrate, thereby screening the metal powder, and the screened metal powder will fall into the collection box, and the metal powder remaining above the screen will fall into the collection box under the action of gravity and vibration, so that the remaining metal powder can be conveniently recovered and the metal powder remaining above the screen can be cleaned.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a screening device for denture 3D printing materials includes a screening structure and a base plate 1, the upper end of the base plate 1 is fixedly connected with a short column 5 and a tall column 6 arranged oppositely, the screening structure includes a spring 7 arranged at the upper ends of the short column 5 and the tall column 6, the upper ends of the springs 7 are provided with side plates 8, a screening bucket 9 is fixedly connected between the side plates 8 arranged oppositely on both sides, and a screen 10 is provided in the screening bucket 9.

[0021] Through the above structure, the metal powder to be screened is placed on the screen 10, and the screening and centralized recovery are achieved. The specific structure is as follows:

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sieve bucket 9 is in an inclined state, and the upper end of the bottom plate 1 is provided with a collecting box 3 cooperating with the screen 10 and a collecting box 2 cooperating with one end of the sieve bucket 9. A handle 4 is fixedly connected to the collecting box 3 for convenient pulling out of the collecting box 3, and an extension plate 12 cooperating with the collecting box 2 is fixedly connected to one end of the sieve bucket 9 for convenient falling of the remaining metal powder into the collecting box 2. The collecting box 3 and the collecting box 2 are placed on the upper end of the base, and a vibration motor 11 is provided on the sieve bucket 9.

[0023] Through the above structure, the metal powder can be screened and the metal powder left above the screen 10 can be collected and recovered.

[0024] Embodiment 2

[0025] like Figure 1 As shown, the sieve bucket 9 is provided with an adjustment knob electrically connected to the vibration motor 11.

[0026] Through the above structure, the output power of the vibration motor 11 can be adjusted by turning the adjustment knob, thereby adjusting the vibration frequency of the sieve bucket 9.

[0027] When the utility model is implemented, when it is used, when it is necessary to screen metal powder, the metal powder is placed on the screen, and the vibration motor is turned on. After the vibration motor is turned on, the screen bucket and the screen will vibrate. During the vibration process, the metal powder with the particle size meeting the requirements will fall into the collection box;

[0028] The metal powder left above the screen due to particle size not meeting the requirements will slide down the inclined screen under the action of the vibrating screen and its own gravity, and finally slide over the extension plate and fall into the collection box. In this way, the metal powder with unqualified particle size can be collected and recovered, and the remaining metal powder above the screen can be cleaned during the screening process, and the metal powder in the collection box can be put back on the screen for secondary screening.
