Description

Technical Field

[0001] The invention relates to the technical field of plastic products, in particular to a plastic product particle batching circulation mixing feeding device. Background Art

[0002] In modern industrial manufacturing, plastic products have become an indispensable part. They are mainly made of plastic particles. In the production process, stirring is one of the most critical production processes of plastic particles. When used, the plastic raw materials will be prepared into particles. Then, according to the needs of different products, the raw material particles need to be evenly mixed with the remaining ingredients for subsequent processing and use.

[0003] The announcement number is: CN118849239B, which discloses a mixing and feeding device for plastic product particle ingredients. The mixing and feeding device drives the filter barrel to rotate, and uses the centrifugal force generated when the filter barrel rotates to screen small particles, while large particles remain inside the filter barrel. The driven gear drives the stirring blade to rotate to guide the particles in the filter barrel downward, and the large particles are transported to the inside of the cylinder. The rotation of the shaft drives the No. 1 cam and the No. 2 cam to rotate synchronously and fit the inner wall of the cylinder, so as to crush the large particles and reduce the volume of the particles.

[0004] However, when the above-mentioned mixing and feeding device is in use, the filter barrel will first filter out the raw material particles that meet the standards, and the above-mentioned mixing and feeding device is mainly used to crush the raw material particles that do not meet the standards. As a result, in actual use, since the raw material particles that meet the standards account for the majority, after the raw materials are put into the filter barrel, they are discharged without being evenly mixed, resulting in poor mixing effect. In addition, when the above-mentioned mixing and feeding device crushes large-particle raw material particles, it crushes them by extrusion and crushing. When crushing plastic particles with different characteristics, some plastic particles will only be squeezed into a flat shape during extrusion and will not be squeezed and crushed. Therefore, the above-mentioned mixing and feeding device can only be used for mixing some plastic particles when in use.

[0005] Based on this, a plastic product granule batching circulation mixing feeding device is now provided, which can eliminate the disadvantages of the existing device. Summary of the invention

A driven friction ring is fixedly arranged on the outer side of the material-dispensing disc 42. The driven friction ring is tightly pressed against the active friction ring 43. The active friction ring 43 is fixedly arranged on the rotating frame. The upper straight line of the grid mesh plate 37 is provided with a blade.

The heater 52 heats the plastic particles inside the mixing box 11, and the auger plate 35 cooperates with the conveying pipe 33 to allow the plastic particles inside the mixing box 11 to flow inside the conveying pipe 33. At this time, the heating pipe 50 can heat the plastic particles inside the conveying pipe 33.

[0040] The auger plate 35 is composed of a heat-conducting layer 55 and two protective layers 54. The heat-conducting layer 55 is located between the two protective layers 54. The protective layer 54 and the heat-conducting layer 55 are both fixedly connected to the mounting shaft 29. When in use, when the heating tube 50 is heated, the heat-conducting layer 55 conducts heat, thereby increasing the heating effect.

When a dividing trough on the dividing roller 15 is aligned with the discharge end of the collecting pipe 14, the raw materials and ingredients inside the collecting pipe 14 fall into the dividing trough. When the dividing trough is aligned with the inner wall of the connecting pipe 13, the second motor 24 is started, and the output end of the second motor 24 drives the first transmission shaft to rotate, and the first transmission shaft drives the sixth bevel gear to rotate, and the first transmission shaft drives the sixth bevel gear to rotate. The six-bevel gear is meshed with several first bevel gears 22 for transmission at the same time, and several mixing plates 19 are connected by synchronous toothed belts 20, so that several mixing plates 19 rotate at the same time, so that the mixing plates 19 also rotate when the dividing roller 15 rotates, so as to increase the premixing effect of the plastic particles inside the dividing trough. When the dividing trough rotates to the feeding end of the feeding pipe 12, the premixed plastic particles fall on the upper end of the throwing plate 28 through the feeding pipe 12, and the third motor 31 is started at the same time, and the mounting shaft 29 drives the throwing plate 28 to rotate, so that the throwing plate 28 throws the plastic particles to the inner wall of the mixing box 11, and then the plastic particles fall on the upper end of the grid plate 37; The plastic particles are thrown to the upper end of the grid mesh plate 37 by the throwing plate 28, and the conveying pipe 33 cooperates with the auger plate 35 to convey the plastic particles at the bottom of the mixing box 11 to one end of the conveying pipe 33, and are discharged to the upper end of the grid mesh plate 37 through the distribution pipe 36. Some qualified plastic particles fall into the mixing box 11 through the sieve holes on the grid mesh plate 37. Since the grid mesh plate 37 and the distribution pipe 36 are both in a rotating state and the rotation directions are opposite, the plastic particles in the mixing box 11 can circulate. When the conveying pipe 33 rotates, the conveying pipe 33 drives the rolling wheel 39 and the material dial 42 to rotate, and the material dial 42 is in close contact with the active friction ring 43, so that the material dial 42 rotates, and the sixth gear is meshed with the third gear 41, so that the rolling wheel 39 rotates, so that when the plastic particles are accumulated on the upper end of the grid mesh plate 37, the dial The material tray 42 first moves the plastic particles on the upper end of the grid mesh plate 37, so that the plastic particles that meet the standards fall down, while the large plastic particles remain on the upper end of the grid mesh plate 37. Then, when the rolling wheel 39 passes by, the rolling wheel 39 squeezes the large plastic particles. Since the upper end of the grid mesh plate 37 is a blade, the large plastic particles are cut, and when the conveying pipe 33 rotates, the conveying pipe 33 drives the third mixing rod and the shifting rod 47 to rotate, so that the plastic particles inside the mixing box 11 are mixed. When the shifting rod 47 is in close contact with the fixed rod 46, since the mounting frame 38 rotates in opposite directions to the conveying pipe 33, the shifting rod 47 shifts the mixing frame 44 to rotate through the fixed rod 46, and when the shifting rod 47 is separated from the fixed rod 46, under the action of the torsion spring 45, the mixing frame 44 rotates to the initial position, so as to increase the mixing effect of the plastic particles inside the mixing box 11.
