[0015] A control method for colored sand production equipment comprises the following steps:
[0016] Step 1. According to the crushing mesh number requirement of the colored sand raw material, the height position of the crushing inner convex is adjusted, the first motor is controlled to drive the threaded rod to rotate, and the threaded rod is threadedly installed in the threaded groove to drive the longitudinal slide cylinder and the limit ring to move upward, thereby driving the crushing inner convex to move upward, reducing the space of the crushing chamber, so that the crushing inner convex can crush the colored sand raw material in the crushing chamber with a large mesh number. On the contrary, the first motor is controlled to drive the threaded rod to rotate in the opposite direction, and the threaded rod is threadedly installed in the threaded groove to drive the longitudinal slide cylinder and the limit ring to move downward, thereby driving the crushing inner convex to move downward, increasing the space of the crushing chamber, so that the crushing inner convex can crush the colored sand raw material in the crushing chamber with a small mesh number, until the height adjustment of the crushing inner convex is completed;
[0017] When the crushing inner convex is lifted, it drives the driving pipe to lift and lower, and drives the middle sliding pipe to slide in the middle of the sleeve sliding cylinder;
[0018] The second step is to control the start of the second motor to drive the driving gear to drive the crown gear to rotate, thereby driving the sleeve slide tube and the middle slide tube to rotate, and then driving the driving tube to rotate, thereby controlling the crushing inner convex to rotate at a high speed. While the driving tube rotates, it drives the driving ring and multiple driving protrusions to rotate. When the driving protrusion and the driven protrusion contact, the driving protrusion pushes up the driven protrusion, thereby driving the discharging convex frame and the inner screen frame to move up in the screening outer frame, and the card slide moves up in the card slide groove to squeeze the spring. When the driving ring and multiple driving protrusions continue to rotate, the driving protrusion and the driven protrusion separate. At this time, the spring resets and drives the card slide to move down in the card slide groove, thereby controlling the discharging convex frame and the inner screen frame to indirectly lift and vibrate in the screening outer frame. When the discharging convex frame and the inner screen frame are indirectly lifted and vibrated in the screening outer frame, the sealing convex moves in the corresponding through groove, and the sealing convex always blocks the corresponding through groove.
[0019] Step 3: Put the crushed colored sand raw materials into the feeding cylinder, and evenly introduce them into the crushing chamber through multiple guide pipes and feed pipes. By controlling the crushing inner convex to rotate at high speed in the bottom groove, the crushing outer cylinder is matched to automatically crush the colored sand raw materials in the crushing chamber;
[0020] Step 4: The crushed colored sand raw materials fall into the inner screen frame through the bottom of the crushing chamber. The discharge convex frame and the inner screen frame are indirectly lifted and vibrated in the screening outer frame to screen the crushed colored sand raw materials falling on the inner screen frame. The powdered raw materials are discharged through multiple screening holes, and the granular colored sand raw materials are retained in the discharge convex frame and the inner screen frame, thereby realizing the synchronous automatic screening of the crushed colored sand raw materials.
[0021] The screened powdered raw materials are discharged through a plurality of screening holes and fall between the outer side of the isolation outer tube and the inner side of the screening outer frame, fall onto the first inclined plate, and are separated and discharged through the first discharge frame;
[0022] After screening is completed, the lifting cylinder is controlled to drive the lifting frame to drive the isolation inner tube to descend, thereby driving the inner partition frame to descend, the sealing convexity disengages from the through slot, and the through slot is opened. Accompanied by the vibration of the discharge convex frame and the inner screen frame, the screened granular colored sand raw materials are discharged into the outer side of the isolation outer tube and the inner side of the isolation inner tube through multiple through slots, fall on the second inclined plate, and are separated and discharged through the second discharge frame, thereby realizing the separation and separate discharge of the powdered raw materials and granular colored sand raw materials after screening.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] 1. By setting up a crushing mechanism and using a screening mechanism in conjunction, the colored sand raw materials in the crushing chamber are automatically crushed and processed. At the same time, the discharge convex frame and the inner screen frame are controlled to indirectly rise and fall and vibrate in the screening outer frame, and the crushed colored sand raw materials are synchronously and automatically screened, thereby improving the overall production efficiency of colored sand.
[0025] 2. By setting up the crushing mechanism, the lifting and lowering of the crushing inner convex can be flexibly controlled according to the crushing mesh requirements, the space of the crushing chamber can be adjusted, and then colored sand of different mesh sizes can be crushed, thereby improving the flexibility of the entire equipment.
[0026] 3. By setting up a screening mechanism, the screened powdered raw materials and granular colored sand raw materials can be separated and discharged separately, which is convenient for the subsequent use of raw materials in different forms. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A control method for colored sand production equipment comprises the following steps:
