Description

Technical Field

[0001] The utility model relates to the technical field of modified plastic production equipment, in particular to a homogenizing bin for modified plastic production. Background Art

[0002] Modified plastics refer to plastic products that are processed on the basis of general plastics and engineering plastics through filling, blending, reinforcement and other methods to improve the flame retardancy, strength, impact resistance, toughness and other properties. In the production process of modified plastics, various plastic particles need to be stirred and mixed, so stirring and mixing equipment is needed.

[0003] The existing homogenizing bin for modified plastic production uses the spiral stirring principle during use. The raw materials are transported to the top of the cylinder through the spiral shaft, and the plastic particles are allowed to fall freely by gravity to achieve homogenization of the plastic particles. For example, Patent No. CN202222546213.7 discloses a plastic particle homogenizing device that adopts this principle. In the above method, during the lifting process, it is necessary to isolate the spiral shaft from the plastic particles through the lifting cylinder, so that the plastic particles are lifted in the lifting cylinder and then discharged through the guide hopper. However, since the lifting cylinder is fixed, the falling direction of the plastic particles is also certain, which easily leads to the aggregation of plastic particles and the inability to make the plastic particles fall evenly in the cylinder, thereby affecting the homogenization effect of the device. Therefore, a homogenizing bin for modified plastic production is urgently needed to solve the above problems. Utility Model Content

[0026] A convex ring 15 is formed on the top of the lifting cylinder 12, and a connecting cavity is opened at a position on the top wall of the homogenizing tank 2 corresponding to the convex ring 15. The lifting cylinder 12 is rotatably connected to the homogenizing tank 2 through the convex ring 15. The outer diameter of the lifting cylinder 12 is smaller than the inner diameter of the material guide pipe 5. The lifting cylinder 12 can rotate in the homogenizing tank 2, thereby changing the discharge direction of the discharge pipe 13.

[0027] The screw shaft 17 is arranged in the lifting cylinder 12 , and the top end of the screw shaft 17 is fixedly connected to the driving wheel 9 . The driving wheel 9 drives the screw shaft 17 to rotate, and the screw shaft 17 lifts the plastic particles at the bottom end of the homogenizing tank 2 .

[0028] The ring gear 14 is fixed on the lifting cylinder 12, and the ring gear 14 is arranged above the discharge pipe 13. The gear 16 is meshed with the ring gear 14. The driven wheel 11 passes through the homogenization tank 2 and is fixedly connected with the gear 16. In the process of discharging the plastic particles after being lifted, the driving wheel 9 drives the driven wheel 11 to rotate through the belt 10, and the driven wheel 11 drives the ring gear 14 to rotate through the gear 16, thereby causing the lifting cylinder 12 to rotate circumferentially, which can change the discharge direction of the plastic particles, make them evenly mixed, and also avoid their aggregation, thereby improving the homogenization effect of the device.

Finally, the mixed plastic particles are discharged through the guide pipe 5.
