Specific implementation method:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 , Figure 2 As shown, a powder ball press machine includes a working chamber 1, a pretreatment bin 2 is fixed on the working chamber 1, a feeding pipe is fixed on the pretreatment bin 2, a stirring assembly 3 is arranged in the pretreatment bin, a fixed ball pressing mold 4 and a movable ball pressing mold 5 are arranged in the working chamber 1, a hydraulic drive device 6 is arranged on the other side of the movable ball pressing mold, the hydraulic drive device can drive the movable ball pressing mold to move, a reducer 7 and a motor 8 connected in sequence for providing power are arranged outside the working chamber 1, and the entire ball press machine adopts the existing technology, and its working principle will not be repeated here.

[0023] like Figure 1 , Figure 3 As shown, a discharge assembly 9 is provided at the bottom of the working chamber 1 , and a material guide screen plate 11 is movably connected inside the discharge assembly 9 , and the material guide screen plate 11 can vibrate, and a discharge pipe is fixed to the side end of the discharge assembly 9 .

[0024] During use, the corresponding driving units of the ball press are started respectively, and the fixed ball pressing mold 4 and the movable ball pressing mold 5 in the working chamber 1 complete the ball pressing operation. After the balls are formed, they fall into the discharging assembly and are finally discharged through the discharging pipe. In the discharging process, the guide screen plate 11 is used to realize the driving effect on the ball and the screening effect on the powder, so that the ball rolls to the discharging pipe to complete the discharging. At the same time, the guide screen plate vibrates, which can shake out the powder for collection and recycling.

[0025] like Figure 4 , Figure 5As shown, the discharging assembly 9 includes a frame 10, in which a material guiding screen plate 11 is movably connected via a limiting assembly, and the top surface of the material guiding screen plate 11 is inclined from the left side to the right side, and is inclined from the rear side to the front side, and the lowest end of the material guiding screen plate 11 is arranged at the discharging pipe.

[0026] During use, the balled spheres enter the material guide screen plate 11. By utilizing the top surface setting of the material guide screen plate 11, the spheres can roll directly to the discharge pipe due to their own gravity to complete the discharge. At the same time, during the rolling process, the material guide screen plate 11 can also complete the screening of powder materials.

[0027] A collecting box 12 is arranged at the lower end of the material guiding screen plate 11, and the collecting box 12 is fixed at the bottom of the frame 10, and the inner bottom surface of the collecting box 12 is inclined from the left side to the right side, and is inclined from the front side to the rear side, and a conduit is fixedly connected to the side end of the collecting box 12, and the conduit is arranged at the lowest point of the inner bottom surface of the collecting box 12, and a valve is fixed on the conduit.

[0028] During use, the collecting box 12 can collect the powder directly discharged from the working chamber 1 and the powder adhered to the sphere for recycling.

[0029] The limiting assembly includes a bracket 13 fixed on the inner wall of the frame 10 , and a plurality of springs 14 are fixedly connected between the top surface of the bracket 13 and the bottom surface of the material guiding screen plate 11 .

[0030] like Figure 5 , Figure 6 As shown, a blowing assembly 15 is disposed on the front side of the material guiding screen plate 11 , the top surface of the material guiding screen plate 11 is arranged in a serrated shape, and the output end of the blowing assembly 15 is arranged toward the top surface of the material guiding screen plate 11 .

[0031] During use, the blowing effect of the blowing component 15 is utilized in the opposite direction to the rolling direction of the sphere. At the same time, the rolling direction of the sphere will not be changed due to the blowing of the blowing component 15, so that the powder on the sphere can be blown down. At the same time, because the top surface of the material guide screen plate 11 adopts a serrated setting, the surface of the material guide screen plate 11 is uneven, and the airflow will generate more friction and resistance when it acts, thereby causing the material guide screen plate 11 to shake, thereby achieving the effect of vibrating and screening the powder.

[0032] The blowing assembly 15 includes a plurality of blowing pipes which are fixedly arranged at an angle on the side wall of the frame 10, and a solenoid valve is fixed on the blowing pipe. An air compressor is fixed on the input end of the plurality of blowing pipes, and the solenoid valve is electrically connected to an external controller. In this way, during use, the solenoid valve is controlled by an external controller to adjust the output of the blowing pipe, thereby further improving the shaking effect of the material guide screen plate 11.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
