A fixed frame 642 is fixedly connected to the top of the circular plate 641. A plurality of through holes are penetrated through the outer circumference of the fixed frame 642, so that the material in the quantitative cylinder 62 can flow into the fixed frame 642.

By opening the semicircular hole 645, the material in the fixed frame 642 flows into the bottom of the inner wall of the metering cylinder 62. The inner wall of the base 1 is rotatably connected to the outer periphery of the mounting shaft 4.

[0039] Reference Figure 2 and Figure 6The bottom end of the delivery pipe 63 is fixedly connected to the outer wall of the mixing box 52. The delivery pipe 63 is fixedly connected to prevent the delivery pipe 63 from falling off. A limiting assembly 65 is arranged on the top of the inner wall of the metering cylinder 62. The limiting assembly 65 is used to limit the sleeve 643 so that the circular plate 641 remains fixed. The limiting assembly 65 includes a limiting plate 651. The inner wall of the limiting plate 651 is elastically connected with a clamping block 653 through a spring 652. The elastic force of the spring 652 allows the clamping block 653 to always maintain a clamping effect with the clamping groove 655 when not affected by external force, thereby limiting the sleeve 643. A lever 654 is fixedly connected to the top of the clamping block 653.

[0040] Reference Figure 2 and Figure 5 The top of the fixed plate 61 is fixedly connected with a motor B54. By starting the motor B54, the rotating shaft 55 is driven to rotate. The output shaft of the motor B54 is fixedly connected with the rotating shaft 55. The rotating effect of the rotating shaft 55 drives the stirring rod 56 and the connecting shaft 58 to rotate. The outer periphery of the rotating shaft 55 is fixedly connected with the stirring rod 56. The rotating effect of the stirring rod 56 is used to stir the mixed material in the mixing box 52 to improve the mixing effect of the mixed material. The bottom end of the rotating shaft 55 is fixedly connected with a connecting shaft 58. The rotating effect of the connecting shaft 58 drives the auger 57 to rotate. The outer wall of the connecting shaft 58 is fixedly connected with the auger 57. The rotating effect of the auger 57 enables the material in the pouring pipe 53 to be uniformly discharged. The outer periphery of the rotating shaft 55 penetrates and is rotatably connected to the inner wall of the fixed plate 61. The outer periphery of the rotating shaft 55 penetrates and is rotatably connected to the inner wall of the mixing box 52.

[0041] Reference Figure 3 and Figure 6 The end of the limiting plate 651 is fixedly connected to the top of the inner wall of the metering cylinder 62. The fixing effect of the limiting plate 651 prevents the limiting plate 651 from falling off. The inner wall of the limiting plate 651 penetrates and is slidably connected to the outer periphery of the sleeve 643. The sliding effect of the sleeve 643 drives the fixed frame 642 and the circular plate 641 to move vertically. A card slot 655 is provided on the right side of the sleeve 643. The card slot 655 is provided with multiple groups. The multiple groups of card slots 655 are used to perform the card connection effect with the card block 653 at different positions, so as to perform the limiting effect on the sleeve 643 at different positions. The outer periphery of the driving rod 654 is slidably connected to the inner wall of the limiting plate 651. The sliding effect of the driving rod 654 drives the card block 653 to slide along the inner wall of the limiting plate 651.

[0042] Reference Figure 6The outer wall of the block 653 is slidably connected to the inner wall of the limit plate 651. Through the sliding effect of the block 653, the block 653 and the slot 655 are engaged or released. The outer wall of the block 653 is engaged with the inner wall of the slot 655. Through the engagement effect of the block 653 and the slot 655, the limit plate 651 limits the sleeve 643.

[0043] Working principle: When the rolling roller needs to be centrifugally cast, the staff starts the motor A3 to drive the installation shaft 4 to rotate, and at the same time drives the mold body 2 to rotate. The staff slides the lever 654 in the direction away from the sleeve 643, driving the block 653 to slide along the inner wall of the limiting plate 651, so that the block 653 releases the clamping effect with the slot 655, and at the same time releases the limiting effect on the sleeve 643. The staff slides the sleeve 643 along the inner wall of the limiting plate 651, and drives the fixed frame 642 and the circular plate 641 to move vertically through the sleeve 643. The height position of the circular plate 641 is adjusted according to the required amount of material used.

[0044] When the height position of the circular plate 641 is adjusted, the staff loosens the lever 654, and the elastic force of the spring 652 causes the clamping block 653 to engage with the clamping groove 655, and at the same time limits the sleeve 643, so that the circular plate 641 remains fixed. The staff loosens the bolt 644 to release the limiting effect on the cylindrical rod 646, rotates the cylindrical rod 646, and drives the semicircular block 647 to rotate, so that the semicircular block 647 closes the semicircular hole 645, and then tightens the bolt 644. Tighten bolt 644 to limit the cylindrical rod 646, and have the staff add the molten material into the metering cylinder 62. When the quantitative addition is completed, release the limit on the cylindrical rod 646, rotate the cylindrical rod 646, and make the semicircular block 647 open the semicircular hole 645, so that the material in the metering cylinder 62 flows from the fixed frame 642 into the semicircular hole 645, flows into the bottom of the inner wall of the metering cylinder 62 through the semicircular hole 645, and then flows into the mixing box 52 from the conveying pipe 63.

[0045] The staff starts the motor B54 to drive the rotating shaft 55 to rotate, and at the same time drives the stirring rod 56 to rotate, and the material in the mixing box 52 is stirred and mixed by the stirring rod 56, and the connecting shaft 58 is driven to rotate by the rotating shaft 55, and the auger 57 is driven to rotate by the connecting shaft 58. Through the rotation effect of the auger 57, the material in the pouring pipe 53 is evenly poured into the mold body 2, and through the rotation effect of the mold body 2, the material in the mold body 2 is centrifugally cast.
