Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic powder production, in particular to a high-speed mixing device for plastic powder production and a mixing method thereof. BACKGROUND

[0002] In the production process of plastic powder, according to the weight and model requirements of the production formula, the corresponding raw materials are weighed, and the weighed raw materials are put into the mixing container through the feeding platform; the container is dragged into the high-speed mixing area and mixed by the high-speed mixer. The mixed material is heated and melted by the extruder, and the extruded material is conveyed to the corresponding crushing device by the cooling steel belt to be crushed into pieces, which are conveyed to the mill by the hydraulic vehicle to be ground into powder. The finished powder with a reasonable particle size is collected and packaged, and after quality inspection, it is transported into the warehouse.

[0003] The application number 202222618157.3 is a plastic powder mixing cylinder, which includes a cylinder with an inner cavity, and a cylinder cover arranged on the top of the cylinder. The cylinder cover includes a first cover arranged on the side wall of the cylinder and a second cover rotatably connected to the middle part of the first cover. The second cover is connected with a stirring mechanism that penetrates into the interior of the cylinder. The stirring mechanism includes a driving stirring assembly located in the middle part of the second cover and a driven stirring assembly located at the edge of the second cover. However, during use, the motor drives the stirring rod to quickly stir the plastic powder raw materials in the mixing cylinder, thereby accelerating the mixing. However, during the rapid rotation of the stirring rod, the stirring rod has better mixing effect on the raw materials at the same level, and has poorer mixing effect on the raw materials at other height levels. At the same time, during the stirring process, part of the raw materials with large weight fall from the rotating raw materials to the bottom of the mixing cylinder under the action of gravity, resulting in a low-weight and high-weight layered distribution of the raw materials in the mixing cylinder, which reduces the mixing effect of the plastic powder raw materials and reduces the use value of the high-speed mixing device for plastic powder production.

[0004] At the same time, when the airflow and the second stirring rod mix the raw materials in the initial feeding treatment assembly, the direction of the airflow is fixed, thereby making the entire stirring a regular stirring, which has limited mixing effect on the raw materials. When removing dust and impurities in the final discharging treatment assembly, the collection hole is easy to be blocked, thereby affecting the dust removal and impurity removal effect. At the same time, when the airflow size for dust removal is fixed, if the discharging is large, the impurities and dust in the middle of the raw materials are difficult to ensure the removal effect, thereby affecting the mixing effect of the equipment.

[0059] During use, different raw materials are introduced into the feeding frame 201 through different feeding covers 202, the second driving motor 205 is started during the introduction process, the second driving motor 205 drives each second stirring rod 211 on the second stirring shaft 210 to stir and mix different raw materials, meanwhile, the air compressor 204 is started, the air compressor 204 blows the raw materials to the outside of the second stirring rod 211 through the through hole 214 in the rotating ball 213 in the blowing hole 209 on the hollow air drum plate 208, so as to realize the preliminary mixing treatment of different raw materials, and the raw materials after the preliminary mixing treatment fall into the inside of the mixing box 1.

[0060] The first driving motor 14 is started, and the first driving motor 14 drives the first stirring rod 12 on the first stirring shaft 11 to stir the raw materials. During the stirring process, the lifting frame 701 is reciprocatingly lifted by the adjusting hydraulic cylinder 702. During the lifting process of the lifting frame 701, the upper surface of the lifting frame 701 gradually pushes the raw materials below to the upper side. With the rotation of the lifting frame 701, the raw materials pushed by the lifting frame 701 present a spiral ascending track, so that the raw materials with large weight below are gradually turned to the upper side, and the mixing effect of the raw materials in the mixing box 1 is better.

[0061] The intermediate adjusting partition plate 3 is moved outward by the adjusting cylinder 9, and the raw materials fall into the flow guide frame 6 from the upper space. The gravity of the raw materials extrudes the hollow self-rotating cylinder 401 to rotate. During the rotation process, the air compressor 204 generates suction in the hollow self-rotating cylinder 401 through the collecting box 402, the dust conveying pipe 406 and the connector 412, so as to guide the dust and impurities in the raw material mixture into the collecting box 402 for collection and filtration. The collection hole 404 adsorbs the raw materials to make the raw materials pass between the various dispersion rods 410. The raw materials after passing through the discharge hole fall down, and the workers collect them.

[0062] During the reciprocating lifting process of the lifting frame 701 by the adjusting hydraulic cylinder 702, the first magnet block in the lifting frame 701 also lifts with the lifting of the lifting frame 701. When the first magnet block rises, the attraction of the first magnet block to the permanent magnet block 215 is enhanced, so that the rotating ball 213 rotates, thereby changing the direction of the airflow sprayed from the through hole 214. When the first magnet block descends, the attraction of the first magnet block to the permanent magnet block 215 is weakened, and under the magnetic attraction of the second magnet block, the rotating ball 213 rotates to the initial state, thereby making the airflow sprayed from the through hole 214 return to the initial direction. By changing the direction of the airflow sprayed from the through hole 214, the mixing effect of the airflow and the second stirring rod 211 on the raw materials is better, the mixing dead angle is reduced, and the mixing effect of the equipment is improved.

[0063] In the process of adjusting the hydraulic cylinder 702 to drive the lifting frame 701 to reciprocatingly lift and lower, with the lifting of the lifting frame 701, the first magnet block in the lifting frame 701 also lifts and lowers. When the first magnet block rises, the distance between the first magnet block and the dispersion rod 410 increases, so that the magnetic attraction of the first magnet block to the dispersion rod 410 weakens. Under the action of the connecting spring rod 413, the sliding long rod 416 moves downward. When the sliding long rod 416 moves downward, the inclination sensor detects that the inclination of the sliding long rod 416 increases, and the corresponding equipment control the rotating speed of the air compressor 204 also increases, so that the airflow ejected from the through hole 214 increases, so that the mixing effect in the initial feed processing assembly 2 is better. When the first magnet block rises, the distance between the first magnet block and the dispersion rod 410 decreases, so that the magnetic attraction of the first magnet block to the dispersion rod 410 strengthens, so that the sliding long rod 416 moves upward, so that the dispersion rod 410 lifts the intermediate adjusting partition plate 3 to the position close to the first driving motor 14, so that the raw materials at the top of the intermediate adjusting partition plate 3 are displaced, so that the raw materials at the top of the intermediate adjusting partition plate 3 are mixed better, and the effect and convenience of using the equipment are improved.

[0064] In the process of adjusting the air cylinder 9 to drive the intermediate adjusting partition plate 3 to move outward, and the raw materials falling into the flow guide frame 6 from the upper space, the falling of the raw materials is dispersed by the action of the dispersion rod 410, and the falling raw materials hit the dispersion rod 410 and the hollow self-rotating cylinder 401. The falling of the raw materials hitting the dispersion rod 410 makes the dispersion rod 410 move downward with the sliding long rod 416, so that the detection value of the inclination sensor increases. The more the raw materials fall, the more difficult it will be to clean the dust in the raw materials. Because the more the raw materials fall, the greater the downward pressure on the dispersion rod 410, that is, the greater the detection value of the inclination sensor, the stronger the power of the air compressor 204, and the stronger the suction of the collection hole 404, the stronger the suction of the collection hole 404 to the dust in the raw materials, which is conducive to cleaning the dust, and strengthens the cleaning intensity of the dust in the raw materials when the raw materials fall, and the falling of the raw materials hits the hollow self-rotating cylinder 401, so that the hollow self-rotating cylinder 401 rotates. The rotation of the hollow self-rotating cylinder 401 under the action of the collection hole 404 and the protrusion can clean the blockage of the collection hole 404, so that the dust collection effect of the collection hole 404 is better.

[0065] The application changes the size and direction of the airflow in the initial feed processing assembly 2 by setting the first magnet block, the second magnet block and the rotating ball 213, so that the mixing effect in the initial feed processing assembly 2 is better, and the dispersion rod 410 can intermittently lift the center position of the intermediate adjusting partition plate 3, so that the material mixing at the upper end of the intermediate adjusting partition plate 3 is more uniform, and the power of the air compressor 204 can be adjusted according to the amount of the discharged material, so that the suction force of the collection hole 404 is adjusted, and the hollow rotating cylinder 401 can be vibrated to clean the blocked collection hole 404, thereby improving the mixing effect and the convenience of use of the equipment.
