When the stepped hole is filled, the suction device is turned on at this time, and suction is sucked into the inside of the material box 7 through the hollow rotating shaft 12, so that a negative pressure is formed inside the material box 7, and then the material in the stepped hole is adsorbed on the material selection mold 8, and then the first lifting cylinder 6 is controlled to lift the end of the first mounting plate 5 upward, so that the remaining material in the material box 7 is gathered to one end, which is convenient for manual collection.

[0037] The working principle of the above technical solution is:

[0038] When the stepped holes on the material selection mold 8 are filled and the remaining materials are collected at one end of the material box 7, it is only necessary to control the first rotary cylinder 11 to turn the material box 7 over, and then the remaining materials can be poured into the collecting hopper 14, and then enter the residual material box 15 from the collecting hopper 14. When the materials in the material selection mold 8 are taken away, it is only necessary to control the second rotary cylinder 17 to rotate the connecting arm 16 to the outside of the mounting frame 4, and then control the rodless cylinder 18 to make the connecting arm 16 climb to the top of the material box 7, and then control the second rotary cylinder 17 to rotate, and rotate the other end of the connecting arm 16 to the top of the material box 7, and finally control the third rotary cylinder 19 to drive the residual material box 15 to rotate, pour the residual materials into the material box 7, and then reset the whole. Then the next material selection operation can be started. No manual loading and unloading is required, which further improves production efficiency.

The material receiving plate 29 and the middle partition plate 28 are elastically connected. The material receiving plate 29 is provided with a plurality of ejector pins 30, and the plurality of ejector pins 30 are respectively located in the through holes of the plurality of middle partition plates 28.

[0041] The working principle of the above technical solution is:

[0042] When the material in the material selection mold 8 is filled and the excess material is discharged, the material selection mold 8 is in an overturned state at this time, and the material therein will not fall under the action of negative pressure. Then the second pushing cylinder 32 is controlled to move, so that the material receiving assembly slides to the bottom of the material selection mold 8, and then the second lifting cylinder is controlled to push the material receiving plate 29 upward, so that the ejector pin 30 passes through the through hole on the pressure plate 26 and contacts the bottom fire table material in the material selection mold 8, and then the suction device is disconnected to make the material lose the negative pressure force, and then the second pushing cylinder 32 is controlled to reset, and then in the process of resetting the ejector pin 30, the material will also enter the through hole on the middle partition plate 28 as the ejector pin 30 resets, thereby realizing the transfer of the material. It should be noted that the setting of the ejector pin 30 is to ensure the stability and guidance of the material during the movement process, so as to ensure that the material enters the through hole of the middle partition plate 28 from the material selection mold 8.

[0043] In an operative manner, it further includes an assembly conveying structure 3, which includes a third mounting plate 33 disposed below the second mounting plate 22, a third lifting cylinder 35 is disposed below the third mounting plate 33, one end of the third lifting cylinder 35 is fixed to the third mounting plate 33, and the other end is fixed to the mounting frame 4, a conveyor belt structure is disposed on the outer side of the third mounting plate 33, and material slide plates are disposed at both ends of the conveyor belt structure and the third mounting plate 33, and the material slide plates connect the third mounting plate 33 and the conveyor belt mechanism, and a feeding cylinder 36 (a push plate is disposed at the end) and a discharging cylinder 37 ( The end plate is provided with a pulling plate), the feeding cylinder 36 is used to push the assembly mold 34 on the conveyor belt structure to the third mounting plate 33, and the discharging cylinder 37 is used to scrape the assembly mold 34 that receives the material on the receiving plate 29 to the conveyor belt structure. An auxiliary cylinder is provided on one end of the third mounting plate 33, and the auxiliary cylinder is arranged on one end of the third mounting plate 33 close to the feeding cylinder 36. The auxiliary cylinder is used to push the assembly mold 34 transported to one end of the third mounting plate 33 to the other end to achieve arrangement, and at the same time, push the assembly mold 34 after the primer table is assembled to the discharging end to ensure the working effect of the discharging cylinder 37.

[0044] The working principle of the above technical solution is:

[0045] After the material is transferred into the material receiving assembly, the first pushing cylinder 27 is controlled to extend, driving the pressing plate 26 to slide, so that the through holes on the pressing plate 26 are staggered with the through holes on the middle partition plate 28, thereby restricting the movement of the bottom fire table material therein, and then the fourth rotary cylinder 24 is controlled to rotate, thereby turning the material receiving assembly over, and with the cooperation of the second pushing cylinder 32, the material receiving assembly is moved to just above the assembly mold 34 placed on the third mounting plate 33 (it should be noted that since the first pushing cylinder 27 is fixed on the second mounting plate 22, when the second pushing cylinder 32 moves, in order to maintain the relative position relationship between the pressing plate 26 and the middle partition plate 28, the first pushing cylinder 27 should also cooperate with the movement of the second pushing cylinder 32, which can be achieved through programming or manual control, of course, the first pushing cylinder 27 can also be directly fixed on the bottom plate 38 and move with the movement of the bottom plate 38), and then the third lifting cylinder 35 is controlled to work to lift the third mounting plate 33 upward, that is, at this time the third The assembly mold 34 on the third mounting plate 33 is fitted with the pressing plate 26, and then the first pushing cylinder 27 is controlled to reset, so that the through holes on the pressing plate 26 and the middle partition plate 28 are aligned, so that the material in the through hole in the middle partition plate 28 enters the blind hole set on the assembly mold 34, and then the second lifting cylinder is used to drive the ejector pin 30 to move and push the material into the assembly mold 34. The assembly mold 34 is provided with a blind hole or other hole for placing the primer shell, that is, the ejector pin 30 here can ensure that all the materials enter the assembly mold 34, and at the same time, it can also ensure that the materials enter the assembly mold 34 and are placed flat and assembled with the primer shell. When the materials are transferred to the assembly mold 34, the third lifting cylinder 35 is reset, and then the assembly molds 34 are sent one by one to the conveyor belt structure to the next process through the cooperation of the discharge cylinder 37 and the auxiliary cylinder, and then the empty assembly molds 34 needed for the next cycle are sent to the third mounting plate 33 through the cooperation of the auxiliary cylinder and the feeding cylinder 36.
