Description

Technical Field

[0001] The present invention relates to the technical field of coating processing, and specifically to a processing technology for raw materials for preparing waterborne coatings. Background Art

[0002] Waterborne coatings are coatings with special uses formed by mixing other dry powders and colloidal materials with water as a solvent. The main effective component is the dry powder raw material. Before mixing and preparation, the raw materials need to be thoroughly crushed so that the particle size after mixing can meet the usage requirements.

[0003] The existing published patent with the publication number CN115625015A introduces a processing technology for raw materials for preparing waterborne coatings, which is completed by an automatic crushing and grinding machine for raw materials for preparing waterborne coatings. The automatic crushing and grinding machine for raw materials for preparing waterborne coatings includes a base, a vertical plate, a support unit, a tank seat opening, a tank body, a reciprocating unit, a transmission unit, etc. After understanding the content of this patent, it is found that its main achieved effect is to perform primary crushing on the raw materials by moving the crushing part up and down, and at the same time rotate the tank body to hammer-crush the raw materials at different positions, and then further grind the materials through the grinding part and rotation;

[0004] However, in the actual operation process, when the tank body is rotating rapidly, the centrifugal force generated will cause larger particle materials to adhere to the side wall of the tank body and be not easily hammered. At the same time, during the grinding process, the materials are extremely easy to adhere to the inner wall of the grinding container, resulting in material caking, which is more unfavorable for feeding. Therefore, a processing technology for raw materials for preparing waterborne coatings is provided specifically to solve the above problems. Summary of the Invention

[0018] The present invention discloses a processing technology for raw materials for preparing water-based coatings, and its beneficial effects are as follows:

[0019] In this processing technology for raw materials for preparing water-based coatings, as the L-shaped support plate moves downward, the piston rod at the bottom moves downward, and the pressure inside the L-shaped air cylinder increases. At this time, the piston rod at the top moves outward, driving the drive rack to slide forward, driving the transmission gear to rotate clockwise. There is a ratchet and pawl between the transmission gear and the turntable. Therefore, when the transmission gear rotates clockwise, it cannot drive the turntable to rotate. Then, after completing one hammering of the material, the output end of the hydraulic cylinder extends, driving the breaking hammer to move upward. At this time, the L-shaped air cylinder moves upward, reducing the pressure inside the L-shaped air cylinder. At this time, the piston rod at the top moves inward, and the drive rack drives the transmission gear to rotate counterclockwise, driving the turntable to rotate counterclockwise by a certain angle through the ratchet and pawl, so that multiple breaking hammers rotate, realizing repeated hammering of the breaking hammers. The hammering will cause the unbroken material to spread to the side of the hammering position, and rotating the breaking hammer adjusts the position of the breaking hammer, which is more conducive to hammering and breaking the unbroken material, improving the material breaking effect.

[0020] In the processing technology of the raw materials for preparing the water-based coating, during the process of the hydraulic cylinder driving the breaker hammer to repeatedly hammer the material for crushing, as the L-shaped support plate moves up and down, the transmission disk is driven to rotate by the eccentric rod. At this time, the drive shaft at the end of the transmission disk drives the transmission shaft to rotate through two sets of bevel gears. The transmission shaft drives the rotating main shaft to rotate through the transmission belt. At this time, the rotating main shaft drives the grinding disk to rotate inside the screening and grinding cylinder, pushing the material inside the screening and grinding cylinder along the side wall and the bottom wall, thereby grinding the material, which falls downward into the grinding bin. Then, the rotating main shaft drives the rolling roller to roll on the top of the secondary sieve plate, roller-pressing and grinding the material, so that the material passes through the secondary sieve plate and falls to the top of the inclined screen mesh, thus synchronously realizing the classification treatment of the material.

[0021] In the processing technology of the raw materials for preparing the water-based coating, when the hydraulic cylinder drives the breaker hammer to repeatedly hammer downward, it will cause the entire L-shaped equipment frame to vibrate up and down. At this time, the vibration screening spring at the bottom of the L-shaped equipment frame enables the L-shaped equipment frame to have a certain amount of up and down vibration screening movement, so that the coarse-hole sieve plate, the screening and grinding cylinder, the secondary sieve plate, the inclined screen mesh, and the inclined guide plate are all vibrated up and down, facilitating the rapid screening and falling of the material. Part of the incompletely crushed material is discharged through the coarse material discharge hopper, while the completely crushed material is discharged through the fine material discharge hopper, avoiding material blockage.

An eccentric rod 14 is rotatably connected to the outer surface of the transmission disc 16, and the top end of the eccentric rod 14 is movably hinged to the L-shaped support plate 2. A driving shaft 17 is installed in the middle of the transmission disc 16. A rotating main shaft 11 is installed between the grinding disc 43 and the rolling roller 57.

Bevel gears 19 are installed on the outer surfaces of the drive shaft 17 and the transmission shaft 18, and the two groups of bevel gears 19 are meshed with each other.

[0043] The top end of the rotating main shaft 11 penetrates through the screening and grinding cylinder 42, and the screening and grinding cylinder 42 is installed at the inner top of the screening and grinding bin 41.

[0044] An L-shaped support base 7 is arranged at the bottom of the L-shaped equipment frame 1. A positioning column 21 is fixedly connected to the upper surface of the L-shaped support base 7. The top end of the positioning column 21 is movably inserted into the inside of the L-shaped equipment frame 1, and a vibration screening spring 22 is arranged at the top of the positioning column 21. A limiting slider 20 is fixedly connected to the side wall of the L-shaped support base 7. A limiting sliding groove 9 is opened on the back surface of the L-shaped equipment frame 1, and the limiting slider 20 is slidably connected inside the limiting sliding groove 9.

[0045] Working principle: When the device is in use, the raw materials are poured into the inside of the crushing cylinder 31 from the position of the feed hopper 32, and then the hydraulic cylinder 6 is started, so that the output shaft of the hydraulic cylinder 6 reciprocates telescopically. When the output end of the hydraulic cylinder 6 contracts, the L-shaped support plate 2 is driven to move downward through the sliding connection frame 10. At this time, the L-shaped support plate 2 drives a plurality of movable shafts 34 to quickly move towards the inner bottom of the crushing cylinder 31 through the turntable 311, so that the plurality of crushing hammers 316 hammer the raw materials inside the crushing cylinder 31. At the same time, the up and down movement range of the crushing hammer 316 is adaptively adjusted through the arranged protective spring 317, so as to prevent the crushing hammer 316 from touching the bottom and the hydraulic cylinder 6 continuing to output when there is too much material, resulting in damage to the hydraulic cylinder 6 and the coarse hole sieve plate 315;

[0046] At the same time, during the above operation, as the L-shaped support plate 2 moves downward, the piston rod 36 at the bottom end moves downward. At this time, the T-shaped shaft 37 is completely inserted into the piston rod 36. Then the L-shaped support plate 2 continues to move downward, so that the piston rod 36 at the bottom is pressed into the inside of the L-shaped air cylinder 35, increasing the pressure inside the L-shaped air cylinder 35. At this time, the piston rod 36 at the top end of the L-shaped air cylinder 35 moves outward, driving the driving rack 39 to slide forward. At this time, the driving rack 39 drives the transmission gear 38 to rotate clockwise. However, in this process, since a ratchet 310 and a ratchet pawl 318 are arranged between the transmission gear 38 and the turntable 311, the turntable 311 cannot be driven to rotate when the transmission gear 38 rotates clockwise;

[0047] Then, after one hammering of the material is completed, the output end of the hydraulic cylinder 6 extends, driving the L-shaped support plate 2 to move upward. Through the movable shaft 34, multiple breaker hammers 316 are driven to move upward. At this time, the piston rod 36 at the bottom slides upward on the outer surface of the T-shaped shaft 37. Then, as the L-shaped support plate 2 continues to move upward, the top of the T-shaped shaft 37 comes into contact with the inner bottom of the piston rod 36. At this time, the piston rod 36 cannot continue to move upward. At this time, the L-shaped pneumatic cylinder 35 continues to move upward, resulting in a decrease in the internal pressure of the L-shaped pneumatic cylinder 35. At this time, the piston rod 36 at the top moves into the L-shaped pneumatic cylinder 35, driving the driving rack 39 to slide backward. At this time, the driving rack 39 drives the transmission gear 38 to rotate counterclockwise. At this time, the transmission gear 38 drives the turntable 311 to rotate counterclockwise by a certain angle, causing the multiple breaker hammers 316 to rotate. At the same time, the rotating cover 33 is driven to rotate along the positioning ring 313 to adjust the next hammering position of the breaker hammers 316. Then, the output shaft of the hydraulic cylinder 6 contracts again for the second hammering, thereby realizing the repeated hammering of the breaker hammers 316, and the hammering position changes each time. During the actual operation, the hammering causes the unbroken material to spread to the side of the hammering position, and rotating the breaker hammers 316 to adjust their positions is more conducive to hammering and crushing the unbroken material;

[0048] At the same time, during the process of the hydraulic cylinder 6 driving the breaker hammers 316 to repeatedly hammer and crush the material, as the L-shaped support plate 2 moves up and down, the eccentric rod 14 drives the transmission disk 16 to rotate. At this time, the drive shaft 17 at the end of the transmission disk 16 drives the transmission shaft 18 to rotate through two sets of bevel gears 19. The transmission shaft 18 drives the rotating main shaft 11 to rotate through the transmission belt 12. At this time, the rotating main shaft 11 drives the grinding disk 43 to rotate inside the screening and grinding cylinder 42, pushing the material inside the screening and grinding cylinder 42 along the side wall and the bottom wall, thereby grinding the material and making it fall downward into the grinding bin 51. Then, the rotating main shaft 11 drives the rolling roller 57 to roll on the top of the secondary sieve plate 52 to roll and grind the material, causing the material to pass through the secondary sieve plate 52 and fall downward to the top of the inclined screen 53;

[0049] At the same time, when the hydraulic cylinder 6 drives the breaker hammers 316 to repeatedly hammer downward, it will cause the entire L-shaped equipment frame 1 to vibrate up and down. At this time, through the vibration screening spring 22 at the bottom of the L-shaped equipment frame 1, the L-shaped equipment frame 1 can have a certain amount of up and down vibration screening movement, so that the coarse-hole sieve plate 315, the screening and grinding cylinder 42, the secondary sieve plate 52, the inclined screen 53, and the inclined guide plate 54 are all subjected to up and down vibrations, facilitating the rapid screening and falling of the material. Some incompletely crushed materials are discharged through the coarse material discharge hopper 55, while the completely crushed materials are discharged through the fine material discharge hopper 56, avoiding material blockage.
