The utility model is further described below in combination with the embodiments.

[0029] See also Figure 1-3 In one embodiment of the present application, a raw material screening machine for powder sintering includes a machine base 1, a controller 3 and a plurality of universal wheels 2, wherein the controller 3 is arranged on the machine base 1, and the plurality of universal wheels 2 are symmetrically arranged on the machine base 1, and the screening machine further includes:

[0030] A feed hopper 4 is arranged on the machine base 1;

[0033] The screening module is arranged between the machine base 1 and the screening box 7 and is used for screening the raw materials entering the screening box 7 .

[0034] In this exemplary embodiment, the screening module includes:

[0035] The screen frame 10 slides through the screening box 7 and the two are connected by an elastic member. The screen frame 10 is formed with a through window 18; the screen mesh 12 is arranged in the through window 18;

[0036] A position adjustment seat 6 is arranged on the machine base 1, and a wave ramp is provided on the position adjustment seat 6, and the wave ramp is slidably matched with one end of the screen frame 10; and

[0037] The electric telescopic rod 9 is movably connected between the side of the screening box 7 away from the adjustment seat 6 and the base 1.

[0038] It should be particularly noted that the elastic member may be a spring 11 , a spring sheet or an elastic steel plate structure. In the present embodiment, the elastic member is preferably a spring 11 , and the spring 11 is connected between the screen frame 10 and the screening box 7 .

[0039] It should be supplemented that a resistance reducing member is provided between one end of the screen frame 10 and the position adjusting seat 6 to reduce the friction resistance between the screen frame 10 and the position adjusting seat 6 .

[0040] Of course, the resistance reducing member may be a ball or a roller 13. In the present embodiment, the resistance reducing member is preferably a roller 13, which is movably disposed at one end of the screen frame 10 and slidingly cooperates with the wave ramp.

[0041] In actual application, the raw materials are poured into the screening box 7 along the feed funnel 4, and the electric telescopic rod 9 is controlled to be energized and continuously extended and retracted, so that the screening box 7 is continuously swung relative to the mounting seat 8, so that the screen 12 is continuously swung, and the raw materials are in a shaking state in the screening box 7. In addition, in this process, the cooperation between the roller 13 and the wave ramp can be utilized to make the screen frame 10 and the screen 12 reciprocate relative to the screening box 7, thereby further improving the screening effect of the raw materials. The whole device has a high degree of automation. By utilizing the electric telescopic rod 9 as a power source, it is possible to achieve the external force application in two directions to the raw materials in the screening box 7. Compared with the traditional unidirectional motion screening method, the screening effect is better and it is not easy to cause the screen 12 to be blocked.

When the No. 1 conductive sheet 16 and the No. 2 conductive sheet 17 meet and contact, the electric telescopic rod 9 can be controlled to perform a telescopic movement, thereby eliminating the need for the staff to manually operate the electric telescopic rod 9.

[0046] How this application works:

[0047] When the raw material is poured into the feed hopper 4, the raw material enters the screening box 7 under the action of its gravity, and the raw material collides with the conflicting blades 15, thereby driving the turntable 14 to rotate, so that the No. 1 conductive sheet 16 at different positions successively meets the No. 2 conductive sheet 17. When the No. 1 conductive sheet 16 and the No. 2 conductive sheet 17 meet and contact, the electric telescopic rod 9 can be controlled to do a telescopic movement. The electric telescopic rod 9 is energized and continuously retracted, so that the screening box 7 is continuously swung relative to the mounting seat 8, so that the screen 12 is continuously swung, so that the raw material is in a shaking state in the screening box 7. In addition, in this process, the cooperation between the roller 13 and the wave ramp can be utilized to make the screen frame 10 and the screen 12 reciprocate relative to the screening box 7, further improving the screening effect of the raw material. The whole device has a high degree of automation. By utilizing a power source of the electric telescopic rod 9, it is possible to achieve the external force action in two directions on the raw material in the screening box 7. Compared with the traditional unidirectional motion screening method, the screening effect is better and it is not easy to cause the screen 12 to be blocked.
