The first-level diagonal brace 9 is used to improve the connection strength between the ladder frame 7 and the first-level platform 8.

[0029] The columns 10 are fixedly installed on the top surface of the primary platform 8. There are four columns 10, and the four columns 10 are distributed in a rectangular shape. A secondary platform 11 is fixedly installed on the top of the four columns 10. A secondary diagonal brace 12 is obliquely arranged between the side wall of the column 10 and the bottom surface of the secondary platform 11.

A support grid frame 23 is obliquely arranged on the cavity wall of the sub-screen cavity 22, and the support grid frame 23 is in a "concave" shape. A sub-screen 24 is fixedly installed on the support grid frame 23. Since the support grid frame 23 is obliquely arranged, the sub-screen 24 is also obliquely arranged. The sub-screen 24 divides the sub-screen cavity 22 into a caking material chamber 25 and a lowering material chamber 26. The caking material chamber 25 is located above the sub-screen 24, and the lowering material chamber 26 is located below the sub-screen 24. An agglomerate material outlet 251 is opened on the bottom surface of the sub-screen seat 21, and the agglomerate material outlet 251 is connected to the agglomerate material chamber 25.

The damping shock absorber 28 is an existing shock-absorbing device, and the function of the damping shock absorber 28 is to reduce the vibration amplitude and reduce the ability of the structure to transmit vibration. Vibration motors 29 are fixedly installed on the two opposite side walls of the sub-screen seat 21, and the vibration motors 29 are used to drive the sub-screen seat 21 to vibrate.

[0037] When the powder screening machine 17 is working, after the powder enters the screening chamber 22, the unagglomerated powder passes through the screening mesh 24 and then passes through the unloading chamber 26 and the feeding chamber 19 in sequence until it enters the inner cavity of the mixing chamber. The agglomerated powder will remain above the screening mesh 24 and flow along the inclined screening mesh 24 to the agglomerated material outlet 251.

After the output shaft of the material distribution motor 40 extends into the slide side cavity 38, a driving bevel gear 41 is coaxially arranged. A top groove 42 is provided on the inner top wall of the slide side cavity 38, and a top bearing 43 which is mounted on the output shaft of the material distribution motor 40 is embedded in the top groove 42.

[0044] like Figure 7 and 8 As shown, a transmission shaft 44 is rotatably arranged in the side cavity 38 of the sliding bucket, and a linkage bevel gear 45 meshing with the driving bevel gear 41 is coaxially mounted on the transmission shaft 44 through a key connection, and a linkage spur gear 46 meshing with the guide rack 35 is coaxially arranged on the transmission shaft 44. Two side grooves 47 are symmetrically provided on the inner side wall of the side cavity 38 of the sliding bucket, and side bearings 48 fitted on both ends of the transmission shaft 44 are embedded in the side grooves 47.

[0045] like Figure 7 and 9 As shown, a loading chamber 49 and a valve hole 50 are sequentially opened downward on the top surface of the material distribution slide 37. The loading chamber 49 is used to store the powder weighed by the powder scale 13, and a material discharge control valve 51 for controlling the on-off of the valve chamber is provided.

[0046] like Figure 7 and 9 As shown, the material discharging control valve 51 includes a valve body 52, which is cylindrical and plug-fitted with the valve hole 50.

[0048] When the unloading control valve 51 is opened, the rotating motor 59 drives the rotating shaft 60 and the rotating valve disc 61 to rotate until the upper material hole 62 and the lower material hole 56 are aligned. At this time, the powder in the loading chamber 49 runs out of the distribution slide 37 through the upper material hole 62 and the lower material hole 56 in turn.

[0049] When the material discharge control valve 51 is closed, the rotary motor 59 drives the rotary shaft 60 and the rotary valve disc 61 to rotate until the upper material passage hole 62 and the lower material passage hole 56 are completely misaligned. At this time, the powder in the loading chamber 49 is restricted from running out of the material distribution slide 37.

[0050] When the distribution mechanism 30 is working, the powder weighed by the powder scale 13 will fall into the loading chamber 49 of the distribution slide 37, and then the unloading control valve 51 will be opened, and then the distribution motor 40 will drive the driving bevel gear 41 to rotate. Since the linkage bevel gear 45 is meshed with the driving bevel gear 41, the linkage bevel gear 45 will rotate accordingly, and then drive the transmission shaft 44 to rotate. The rotation of the transmission shaft 44 will drive the linkage spur gear 46 to rotate. Since the linkage spur gear 46 is meshed with the guide rack 35, the distribution slide 37 will make horizontal reciprocating linear motion above the screen seat, so that the powder can be evenly delivered to the sub-screen 24.
