Description

Technical Field

[0001] This utility model relates to the field of powder modification, and more specifically, it relates to an ultrafine powder surface modification machine. Background Technology

[0002] Powder modification refers to the treatment of powder particles through physical or chemical methods to intentionally change the physicochemical properties of the powder. This can significantly affect the powder's flowability, hygroscopicity, and dispersibility, thereby improving the powder's application performance.

[0003] The patent with publication number CN220405607U discloses an inorganic powder wet surface modification device, which includes a modification box, a bottom plate, a U-shaped plate and a mounting plate. The top of the modification box is equipped with a U-shaped plate, and both ends of the U-shaped plate are equipped with first sliding components. A lifting plate is slidably installed on the inner side of the first sliding component, and both ends of the bottom of the lifting plate are equipped with connecting plates, which all pass through the modification box.

[0004] The modification device in the above scheme can stir and mix inorganic powder and modifier, so that the modifier can be uniformly coated on the outside of inorganic powder particles. Ultrasonic waves are emitted by an ultrasonic generator. Through the cavitation effect of ultrasound, the inorganic powder particles can be dispersed to prevent particle agglomeration and ensure that the modifier can be uniformly coated on the outside of the particles.

[0005] Although this modification device can effectively prevent powder particles from agglomerating to improve the coating rate, since it places both the powder and the modifier inside the modification chamber for modification, the ultrasonic generator can only prevent powder agglomeration when dispersing the powder. Once the powder stops agglomerating, the stirrer cannot effectively mix the powder and modifier in the corner of the modification chamber, resulting in a low powder surface coating rate.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] An ultrafine powder surface modification machine, such as Figures 1-4As shown, the device includes a housing 1, a placement plate 2 slidably connected to the housing 1, a screen 3 fixedly connected to the housing 1 above the placement plate 2, and a sliding cover 4 slidably connected between the housing 1 and the placement plate 2 and the screen 3. The sliding cover 4 can be pulled out to add a modifier to the placement plate 2. After adding the modifier, the sliding cover 4 is reset. After modification, the sliding cover 4 is pulled out again, and then the powder inside the housing 1 is extracted using a suction device. A placement frame 5 is fixedly connected to the upper side of the housing 1, and a motor 6 is fixedly connected to the placement frame 5. A rotating plate 7 is fixedly connected to the output shaft of the motor 6, with the bottom side of the rotating plate 7 in contact with the screen 3. The motor 6 is equipped with a mechanism for squeezing the powder to make it adhere to the screen 3. The extruder, motor 6, and housing 1 are equipped with a vibration assembly for vibrating the placement plate 2. When modification begins, the modifier is first added to the placement plate 2, and then the powder is placed on the screen 3. After the powder is placed, the motor 6 is started to drive the rotating plate 7 to start rotating. While the rotating plate 7 is rotating, the extruder will continuously extrude the powder to ensure that all the powder passes through the screen, avoiding agglomeration, and causing the powder to fall onto the placement plate 2 for modification. At the same time as the motor 6 is turned on, the vibration assembly is triggered to continuously vibrate the placement plate 2, so that the modifier can evenly coat the outside of the powder particles, thereby completing the modification operation, avoiding agglomeration, and improving the powder surface coating rate.

[0024] like Figures 1-2 As shown, the extrusion component includes a pressure plate 8 slidably connected to the output shaft of the motor 6, a positioning frame 9 rotatably connected to the motor 6, and several spring telescopic rods 10 connected to the positioning frame 9. The telescopic ends of the spring telescopic rods 10 are fixedly connected to the pressure plate 8. The outer wall of the pressure plate 8 is in contact with the inner wall of the box 1. The pressure plate 8 is slidably connected to the rotating plate 7. A detachable cap 81 is connected to the pressure plate 8. When the spring telescopic rods 10 are in the normal state, the pressure plate 8 is in contact with the screen 3. A sliding groove 11 is opened on the inner wall of the box 1 on the upper side of the pressure plate 8. Several positioning rods 12 are slidably connected to the sliding groove 11. The several positioning rods 12 are respectively fixedly connected to the several spring telescopic rods 10. The spring telescopic rods 10 are slidably connected to the positioning frame 9. The sliding groove 11 is wavy.

[0025] like Figures 1-2As shown, when the rotating plate 7 rotates, it will drive the pressure plate 8 and the spring telescopic rod 10 to rotate together. When the spring telescopic rod 10 rotates with the pressure plate 8, it will drive the positioning rod 12 to move within the wavy groove 11. When the positioning rod 12 moves to a position in the wavy groove 11 away from the screen 3, a gap will appear between the pressure plate 8 and the screen 3. At this time, the cap 81 can be unscrewed to add powder to the screen 3. Then, the positioning rod 12 continues to move within the wavy groove 11, and the spring telescopic rod 10 will become compressed. At this time, the pressure plate 8 rotates, and the pressure plate 8 will be compressed due to the presence of the spring telescopic rod 10. As the powder is continuously compressed, it remains in contact with the screen 3. The powder then falls into the housing 1 through the gaps in the screen 3 until the screen 3 and the pressure plate 8 are in contact. The spring returns to its normal state, and at the same time, the positioning rod 12 moves within the wavy groove 11, causing the spring extension rod 10 to slide up and down on the positioning frame 9. This causes the pressure plate 8 to move away from the powder and then closer to it. This cycle compacts the powder, allowing it to be evenly spread on the screen 3. This method allows for continuous compression of the powder and avoids hollow areas within the powder, thereby improving work efficiency.

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, several fixing blocks 13 are fixedly connected to the upper side of the housing 1. A rotating rod 14 is rotatably connected to the fixing blocks 13. A hammer 15 for striking the upper side of the pressure plate 8 is provided on the rotating rod 14. The end of the rotating rod 14 away from the fixing blocks 13 is connected to the fixing blocks 13 through a torsion spring 141. When the torsion spring 141 is in the normal state, the hammer 15 contacts the pressure plate 8. The hammer 15 includes a hammer rod 151 and a rubber hammer head 152 fixedly connected to the hammer rod 151, which can prevent damage to the pressure plate 8. The hammer rod 151 is fixedly connected to the rotating rod 14. When the positioning rod 12 is in the wavy sliding... When the positioning rod 12 moves upward in the groove 11, it will contact the hammer rod 151 and push the hammer rod 151 to rotate. At this time, the torsion spring 141 is in a deformed state. As the positioning rod 12 continues to move in the groove 11, the positioning rod 12 will contact the rubber hammer head 152. When the positioning rod 12 passes the rubber hammer head 152 and no longer contacts the rubber hammer head 152, the torsion spring 141 will reset, so that when the pressure plate 8 is in the rising stage, it will drive the rubber hammer head 152 to strike the upper side of the pressure plate 8, knocking the powder adhering to the pressure plate 8 onto the screen 3, thereby avoiding waste and improving work efficiency.

[0027] like Figures 3-4As shown, the oscillation assembly includes several spring telescopic rods 16 fixedly connected to the bottom side of the housing 1, a circular plate 17 fixedly connected to the output shaft of the motor 6 on the lower side of the placement plate 2, and several protrusions 18 fixedly connected to the outer wall of the circular plate 17. When the spring telescopic rods 16 are in the normal state, they are located between two adjacent protrusions 18. The top side of the telescopic end of the spring telescopic rod 16 is hemispherical. After the motor 6 is started, the output shaft of the motor 6 will drive the circular plate 17 and the protrusions 18 on it to rotate. When the protrusions 18 rotate, they will contact the hemispherical surface of the spring telescopic rods 16, causing the spring telescopic rods 16 to retract. Then the protrusions 18 continue to rotate. When the protrusions 18 no longer contact the spring telescopic rods 16, the spring telescopic rods 16 reset and hammer the placement plate 2. By repeating this cycle, the placement plate 2 can be continuously oscillated.

[0028] like Figures 3-4 As shown, a protective pad 19 is fixedly connected to the bottom side of the placement plate 2, which can protect the placement plate 2 and improve its service life.

[0029] like Figures 2-4 As shown, a fixing ring 20 is fixedly connected to the placement plate 2. The outer wall of the fixing ring 20 is in contact with the inner wall of the box 1. The inner wall of the fixing ring 20 is inclined so that when the powder falls from the screen 3, it can prevent the powder from falling into the gap between the placement plate 2 and the box 1 and being difficult to remove.

[0030] Working principle: When modification is required, first pull out the sliding cover 4 and add the modifier to the placement plate 2. After adding the modifier, reset the sliding cover 4. Then, unscrew the cap 81 and put the powder on the screen 3. After putting in the powder, tighten the cap 81. After unscrewing the cap 81 and adding powder to the screen 3, the spring extension rod 10 is in a compressed state. Then, start the motor 6 to drive the rotating plate 7 to start rotating. While the rotating plate 7 is rotating, it will drive the pressure plate 8 to rotate as well. And while the pressure plate 8 is rotating, it will... The presence of the spring telescopic rod 10 causes the pressure plate 8 to continuously compress the powder, keeping the powder in contact with the screen 3. As the spring telescopic rod 10 rotates with the pressure plate 8, it also drives the positioning rod 12 to move within the wavy groove 11. When the positioning rod 12 moves within the wavy groove 11, it causes the spring telescopic rod 10 to slide up and down on the positioning frame 9. This causes the pressure plate 8 to move away from the powder and then closer to the powder. This cycle can compact the powder and allow it to be evenly spread on the screen 3.

[0031] As the positioning rod 12 moves upward within the wavy groove 11, it contacts the hammer rod 151 and pushes it to rotate, causing the torsion spring 141 to deform. As the positioning rod 12 continues to move within the groove 11, it contacts the rubber hammer head 152. When the positioning rod 12 passes the rubber hammer head 152 and no longer contacts it, the torsion spring 141 resets, causing the pressure plate 8 to strike the upper side of the pressure plate 8 with the rubber hammer head 152 during the rising phase, thus removing the powder adhering to the pressure plate 8. The body is knocked onto the screen 3, thus avoiding waste and improving work efficiency. At the same time as the motor 6 is turned on, the output shaft of the motor 6 will drive the circular plate 17 and the protrusion 18 on it to rotate. When the protrusion 18 rotates, it will contact the hemispherical surface of the spring telescopic rod 16, causing the spring telescopic rod 16 to retract. Then the protrusion 18 continues to rotate. When the protrusion 18 no longer contacts the spring telescopic rod 16, the spring telescopic rod 16 resets and hammers the placement plate 2. This cycle can continuously vibrate the placement plate 2.

[0032] This method can make the modifier uniformly coat the outside of the powder particles and avoid agglomeration, thereby improving the surface coating rate of the powder. It can also treat the pressing plate 8 to avoid powder adhering to the pressing plate 8 and causing waste.
