When the hemispherical mold 18 is replaced by this device, there is no need to manually reset and align the rotating frame 12 every time, which reduces the time for operators to replace the hemispherical mold 18 and is convenient for operators to use.
[0021] In this embodiment, one end of the rotating shaft 11 close to the fixed shaft 10 passes through the inner wall of the heating box 2 and is fixedly installed with a rotating frame 12. The center line of the squaring block 19 is set at an angle of 10° with the upper plane of the rotating frame 12. A plurality of connecting shafts 14 are equidistantly rotatably installed on the inner wall of one side of the rotating frame 12. Gears 17 are fixedly installed at one end of the plurality of connecting shafts 14. Two adjacent gears 17 are meshed with each other. A conical top 36 is fixedly installed on the outer surface of the gear 17 away from the rotation center of one end of the connecting shaft 14. A plurality of electric telescopic rods 13 are equidistantly fixed on the inner wall of the other side of the rotating frame 12. The electric telescopic rod 13 is resistant to high temperature and is convenient for use at high temperature. A bearing 37 is fixedly installed on the telescopic end of the electric telescopic rod 13. A base 35 is fixedly installed on the outer ring of the bearing 37. The base 35 rotates close to one end of the connecting shaft 14 The outer surface of the center is fixedly installed with the same conical top 36, a group of two hemispherical molds 18 are arranged between the two relatively conical tops 36, and the outer surface of the rotation center of the hemispherical mold 18 is provided with a conical hole 34 matching the conical top 36. The end of the fixed shaft 10 close to the rotating shaft 11 passes through the inner wall of the heating box 2 and is fixedly installed with a first bevel gear 15, and the outer surface of the connecting shaft 14 close to the first bevel gear 15 is fixedly installed with a second bevel gear 16, and the second bevel gear 16 is meshed with the first bevel gear 15. The other end of the rotating shaft 11 passes through the outer surface of the workbench 1 and is fixedly installed with a second pulley 7. The outer surface of the workbench 1 close to the second pulley 7 is fixedly installed with a driving motor 4, and the output end of the driving motor 4 is fixedly installed with a first pulley 5, and the outer surfaces of the first pulley 5 and the second pulley 7 are sleeved with belts 6.
[0022] The operator places the two hemispherical molds 18 between the two conical tips 36 so that the bottom surface of the hemispherical mold 18 close to the gear 17 and the conical hole 34 are against one of the conical tips 36, and the other conical tip 36 is driven to abut against the other conical hole 34 by the extension movement of the telescopic end of the electric telescopic rod 13. When the conical tip 36 abuts against the conical hole 34, there is sufficient friction force to facilitate the subsequent rotation of the hemispherical mold 18. The position of the two hemispherical molds 18 can be fixed quickly and conveniently through this device, which is convenient for the subsequent rotation movement; then the user starts the pneumatic telescopic rod 28 to retract its telescopic end, thereby driving the box cover 3 to seal the heating box 2; the first pulley 5 is driven to rotate by the driving motor 4, and the first pulley 5 drives the second pulley 7 to rotate through the belt 6, so that the second pulley 7 drives the rotating shaft 11 to rotate, and the rotating frame 12 is driven to rotate through the rotating shaft 11. The rotating frame 12 drives multiple groups of hemispherical molds 18 to rotate. At the same time, the rotating frame 12 drives the second bevel gear 16 to rotate. The second bevel gear 16 rotates itself by meshing with the first bevel gear 15. The second bevel gear 16 drives multiple groups of hemispherical molds 18 to rotate by gear 17 and conical top 36. Through the rotation and rotation of the hemispherical mold 18, the caprolactam raw material and auxiliary raw materials such as caustic soda inside can be evenly dispersed in the interior of the hemispherical mold 18 through centrifugal force. The interior of the heating box 2 is heated by an electric heater. When the temperature rises to 140°C, the heating is stopped and the temperature inside the heating box 2 is maintained at 140°C, so that the caprolactam raw material and auxiliary raw materials such as caustic soda undergo a polymerization reaction, and the solid is transformed into a liquid. Then, through the movement of the hemispherical mold 18, the liquid polymer adheres to the inner wall of the hemispherical mold 18 to form a fully enclosed floating ball.
[0023] In this embodiment, a discharge port 8 is penetrated through the outer surface of the heating box 2 away from the box cover 3, and a discharge plate 9 is hinged at the bottom of the discharge port 8. Baffles are fixedly installed on the outer surfaces of the discharge plate 9 near both sides. A transmission shaft 30 is rotatably installed on the inner wall of the heating box 2 away from the turntable 23, and a guide rod 32 is fixedly installed on the end of the transmission shaft 30 close to the discharge plate 9. A guide groove 33 is penetrated through the outer surface of the guide rod 32 close to the top, and a guide column 38 is fixedly installed on the outer surface of the discharge plate 9 near the guide rod 32. The guide column 38 is slidably installed on the inner wall of the guide groove 33. The other end of the transmission shaft 30 penetrates the outer surface of the heating box 2 and is fixedly installed with a second driving block 31. The top of the second driving block 31 is rotatably installed with a second driving rod 29, and the top of the second driving rod 29 is rotatably installed with another fixed column 20.
[0024] The second driving rod 29 is driven to move by another fixed column 20, and the second driving rod 29 drives the transmission shaft 30 to rotate through the second driving block 31, so that the transmission shaft 30 drives the guide rod 32 to move close to the box cover 3, and the guide rod 32 drives the discharge plate 9 to rotate close to the box cover 3 through the guide groove 33 and the guide column 38, so that the top of the discharge plate 9 is rotated to the bottom of the hemispherical mold 18 and tilted. At this time, the telescopic end of the electric telescopic rod 13 retracts and moves, and the hemispherical mold 18 will fall above the discharge plate 9, slide from the discharge port 8 along the discharge plate 9 to the inside of the collection box below, and wait for the hemispherical mold 18 to return to room temperature. The operator separates the two hemispherical molds 18 and then takes out the caprolactam float inside. The device facilitates the quick removal of the caprolactam float and can prevent the operator from manually holding the hemispherical mold 18 and scalding himself.
[0025] In the present embodiment, it should be noted that, by setting the second bevel gear 16, the center of gravity of the rotating frame 12 is biased toward the position of the second bevel gear 16. When the drive motor 4 stops, the rotating frame 12 will rotate downward due to the offset of the center of gravity. Since the angle between the straightening block 19 and the rotating frame 12 is 10°, it can be ensured that the top block 27 will not be pressed against the top of the circular chamfer of the straightening block 19, resulting in the top block 27 being unable to drive the straightening block 19 to reset.
[0026] It should be noted that when the present invention is in use, the operator first puts the caprolactam raw material and auxiliary raw materials such as caustic soda into the interior of the two hemispherical molds 18 according to the use requirements, and then snaps the two hemispherical molds 18 together through matching positioning steps, so that the interiors of the two hemispherical molds 18 are combined into an integral sphere; the operator places the two hemispherical molds 18 between the two conical tops 36, so that the bottom surface and the conical hole 34 of the hemispherical mold 18 close to the gear 17 are against one of the conical tops 36, and the other conical top 36 is driven to abut against the other conical hole 34 through the extension movement of the telescopic end of the electric telescopic rod 13. When the conical top 36 and the conical hole 34 are against each other, there is sufficient friction force, which is convenient for the subsequent rotation of the hemispherical mold 18. The position of the two hemispherical molds 18 is fixed quickly and conveniently through this device, which is convenient for the subsequent rotation movement; then the user starts the pneumatic telescopic rod 28 to retract its telescopic end, thereby driving the box cover 3 to seal the heating box 2; the first pulley 5 is driven to rotate by the driving motor 4 The first pulley 5 drives the second pulley 7 to rotate through the belt 6, so that the second pulley 7 drives the rotating shaft 11 to rotate, and the rotating frame 12 is driven to rotate through the rotating shaft 11, so that the rotating frame 12 drives the multiple groups of hemispherical molds 18 to rotate. At the same time, the second bevel gear 16 is driven to rotate through the rotating frame 12, and the second bevel gear 16 rotates by meshing with the first bevel gear 15. The second bevel gear 16 drives the multiple groups of hemispherical molds 18 to rotate by themselves through the gear 17 and the conical top 36. The caprolactam raw material and auxiliary raw materials such as caustic soda can be evenly dispersed in the hemispherical mold 18 by centrifugal force through the movement. The interior of the heating box 2 is heated by the electric heater. When the temperature reaches 140°C, the heating is stopped and the temperature inside the heating box 2 is kept at 140°C, so that the caprolactam raw material and auxiliary raw materials such as caustic soda undergo a polymerization reaction and are transformed from solid to liquid. Then, through the movement of the hemispherical mold 18, the liquid polymer is attached to the inner wall of the hemispherical mold 18 to form a fully enclosed floating ball.When replacing the hemispherical mold 18, the box cover 3 is driven to open and move through the extension movement of the telescopic end of the pneumatic telescopic rod 28, and the movement of the box cover 3 drives the two fixed columns 20 to move, one of the fixed columns 20 drives the first driving block 22 to rotate in the direction close to the box cover 3 through the first driving rod 21, so that the first driving block 22 drives the turntable 23 to rotate, and the turntable 23 drives the sliding rod 26 to slide upward through the connecting rod 24, so that the sliding rod 26 drives the top block 27 to slide upward, and the top block 27 is abutted against the outer surface of the straightening block 19, so that it drives the straightening block 19 to reset and move, when the arc angle at the top of the top block 27 is completely fitted with the arc groove, the straightening block 19 is completely reset, and at the same time, the arc angle at the top of the top block 27 is completely fitted with the arc groove, ensuring that the rotating frame 12 will not shake when replacing the hemispherical mold 18. When the hemispherical mold 18 is replaced by this device, there is no need to manually reset and straighten the rotating frame 12 every time. , reducing the time for operators to replace the hemispherical mold 18, making it convenient for operators to use; another fixed column 20 drives the second driving rod 29 to move, and the second driving rod 29 drives the transmission shaft 30 to rotate through the second driving block 31, so that the transmission shaft 30 drives the guide rod 32 to move close to the box cover 3, and the guide rod 32 drives the discharge plate 9 to rotate close to the box cover 3 through the guide groove 33 and the guide column 38, so that the top of the discharge plate 9 rotates to the bottom of the hemispherical mold 18 and is tilted. At this time, the telescopic end of the electric telescopic rod 13 retracts and moves, and the hemispherical mold 18 will fall above the discharge plate 9, slide along the discharge plate 9 from the discharge port 8 to the inside of the collection box below, and wait for the hemispherical mold 18 to return to room temperature. The operator separates the two hemispherical molds 18 and then takes out the caprolactam float inside.
