[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The powder conveyor transports the fluorite powder material inside the feeder to the storage tank for storage. The air conveyor lifts the fluorite powder material and conveys it to the roller ball press through the connecting pipeline by the screw conveyor to be squeezed into spheres. The sphere material enters the discharge pipeline and triggers the internal sensor to close the electric sealing valve. The air pump generates high-pressure gas and sprays it through the nozzle on the inner wall of the annular nozzle pipe to increase the air pressure under the discharge pipeline, thereby cushioning the sphere material falling inside the discharge pipeline to reduce the falling speed:

[0022] 2. The air pump inflates the three air cushions, allowing the spherical materials to fall into the material bracket under the cushioning effect of the air cushions. The three-axis mobile module drives the transfer mechanism to move to the upper rear side of the drive assembly. The drive motor, driven by the belt drive, drives the material bracket to flip on the inside of the base to pour the spherical materials into the storage tank cavity.

[0023] 3. The second electric push rod drives the moving seat to reciprocate left and right inside the fixed frame. The moving seat drives the upper and lower rotating seats to rotate in a staggered manner under the cooperation of the connecting rod, so that the driving gear rotates intermittently in the opposite direction. The gear rings on the upper and lower sides drive the turntable to drive the storage tank to rotate to the corresponding position below the transfer mechanism in turn. The first electric push rods on the upper and lower sides of the rear side drive the solenoid valves at the corresponding positions to connect with the first airtight valves at the corresponding positions, so that the annular airbag expands and thus fixes the spherical material. The electric door opens the multi-stage telescopic platform to drive the multi-material transfer mechanism to move out of the box cavity. The first electric push rods at the upper and lower ends of the front side drive the front solenoid valve to connect with the first airtight valve to extract the gas inside the annular airbag to release the fixation of the spherical workpiece, so that the staff can take out the workpiece.

[0024] This optimizes the fluorite powder spherical preparation process, adopts a transfer and transportation method of the spherical workpiece with protective measures to reduce the occurrence of collision and deformation of the finished spherical workpiece, and effectively solves the problem of powder shedding, irregular shape and waste of fluorite powder raw materials caused by collision during the transportation of the finished spheres of the existing fluorite powder extrusion ball making machine.

[0041] The working process of the fluorite powder ball press machine is as follows:

[0042] Step 1: The staff controls the control module 7 to start the feeder 8, the powder conveyor 9, the air conveyor 11 and the screw conveyor 12 in sequence. The staff pours the fluorite powder into the feeder 8. The powder conveyor 9 conveys the fluorite powder material inside the feeder 8 to the storage tank 10 for storage. The air conveyor 11 lifts the fluorite powder material inside the storage tank 10 and lifts it from the internal feed port of the screw conveyor 12 and conveys it to the inside of the screw conveyor 12. The screw conveyor 12 conveys the fluorite powder material inside itself horizontally to the inside of the connecting pipe 23, and enters the roller ball press 26 through the connecting pipe 23. The staff controls the control module 7 to start the roller ball press 26, the air pump 24, the vacuum conveying system 27 and the drive module 53 in sequence. The roller ball press 26 squeezes the internal fluorite powder material into a sphere. The sphere material enters the lower discharge pipe 57 and triggers the sensor 58 inside the discharge pipe 57. The sensor 58 sends The control module 7 sends a signal internally, and the preset program inside the control module 7 controls the electric sealing valve 55 to close to seal the lower part of the inner cavity of the annular nozzle pipe 56. The air pump 24 generates high-pressure gas and discharges it into the inner part of the annular nozzle pipe 56 through the conduit connected to the annular nozzle pipe 56, and sprays it out through the nozzle on the inner wall of the annular nozzle pipe 56 to increase the air pressure below the discharge pipe 57, thereby buffering the spherical material falling inside the discharge pipe 57 to reduce the falling speed. The electric sealing valve 55 opens to cause the spherical material to pass through the annular nozzle pipe 56 and the inner cavity of the electric sealing valve 55 in turn and enter the rear side of the inner cavity of the material pipe 51. The vacuum conveying system 27 extracts the powder from the inner part of the material pipe 51 and conveys it to the inside of the roller ball press 26 for re-extrusion to improve the utilization rate. The driving module 53 drives the spiral conveying roller 52 to rotate in the inner cavity of the material pipe 51, so that the spherical material in the inner cavity of the material pipe 51 moves forward along the spiral groove outside the spiral conveying roller 52 and out of the inner cavity of the material pipe 51:

[0043] Step 2: The air pump 24 inflates the three air cushions 66, so that the spherical material moved out of the inner cavity of the material pipe 51 falls into the inner cavity of the material holder 62 under the cushioning effect of the air cushions 66. The staff controls the control module 7 to start the three-axis movement module 28 and the drive motor 63. The three-axis movement module 28 drives the transfer mechanism 6 to move to the upper rear side of the drive assembly 4. The drive motor 63 drives one end of the pulley inside the belt transmission member 64 to rotate. Then, under the transmission effect of the belt transmission member 64, the material holder 62 is driven to flip inside the base 61 to pour the spherical material inside the material holder 62 into the inner cavity of the storage tank 37 at the corresponding position on the rear side;

[0044] Step 3: The staff controls the control module 7 to start the second electric push rod 46 and the first electric push rod 33. The second electric push rod 46 drives the movable seat 47 to reciprocate left and right inside the fixed frame 42 by its own extension and contraction, and drives the rotating seat 45 at the corresponding positions on the upper and lower sides to rotate in an offset manner with the cooperation of the connecting rod 48, so that the rotating seat 45 drives the driving gear 44 at the corresponding position to rotate intermittently in opposite directions with the cooperation of the upper and lower rotating shafts 43. Since the upper and lower gear rings 36 are engaged with the driving gear 44, the upper and lower gear rings 36 drive the turntable 35 to rotate under the action of the rotational force of the driving gear 44, causing the storage slots 37 in the upper and lower turntables 35 to rotate to the corresponding positions below the transfer mechanism 6 in turn, and the spherical material can fall from the storage slot 37 in the upper turntable 35 into the storage slot 37 in the lower turntable 35. The first electric push rods 33 on the upper and lower sides of the rear side extend and contract by themselves, driving the solenoid valves 34 at the corresponding positions to be inserted into the inner cavity of the mounting slot 39 in turn. The air in the annular airbag 38 is discharged from the connecting passage between the rear solenoid valve 34 and the first airtight valve 310 to expand the annular airbag 38, thereby fixing the spherical material. After the storage tank 37 in the upper and lower turntables 35 is filled with spherical materials, the staff controls the control module 7 to start the electric door 25, the multi-stage telescopic platform 22 and the multi-stage lifting module 31. The electric door 25 opens to enable the multi-stage telescopic platform 22 to drive the multi-material transfer mechanism 3 to move out of the inner cavity of the box body 21. The multi-stage lifting module 31 drives the turntable 35 to a specified height position with the cooperation of the drive component 4. The first electric push rods 33 at the upper and lower ends of the front side extend and shorten to drive the front solenoid valve 34 to be inserted into the inner cavity of the upper and lower mounting slots 39 in turn and connected to the first airtight valve 310 at the corresponding position. The air pump 24 extracts the air in the annular airbag 38 through the connecting passage between the front solenoid valve 34 and the first airtight valve 310 to release the fixation of the spherical workpiece, so that the staff can take out the workpiece.
