Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of plastic particle processing, and particularly to a rapid granulation device for plastic particle processing. Background Art

[0002] Plastic particles are important raw materials in the plastics industry and are widely used in many fields such as packaging, construction, automobiles, electronic appliances, etc. There are many types of plastic particles, which can be classified into various types such as PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene copolymer) according to the material.

[0003] During the process of plastic particle processing, one of the processes is to perform granulation operation on plastic particles. At present, when the traditional plastic particle granulation equipment performs granulation operation through a cutting roller, with the continuous operation of the cutting roller, a certain amount of heat will accumulate on it, and these heats will have an impact on plastic particles, resulting in the adhesion of plastic particles to the cutting roller, thus affecting the normal operation of granulation and reducing the granulation processing efficiency of plastic particles. For this reason, the present utility model proposes a rapid granulation device for plastic particle processing. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a rapid granulation device for plastic particle processing to solve the problem that the existing plastic particle processing equipment is not conducive to production.

[0005] The embodiments of the present application provide a rapid granulation device for plastic particle processing, including a housing. A feeding housing is fixedly installed on the top surface of the housing. Two cutting rollers are symmetrically arranged on the left and right in the inner cavity of the housing. A plurality of first through holes are uniformly distributed on the side wall of the cutting roller. A circular groove is opened at the center of the rear side wall of the cutting roller. A fixed pipe is movably connected in the circular groove. The fixed pipe penetrates through the rear side wall of the housing and is fixedly connected to the housing. A plurality of second through holes are uniformly distributed on the side wall of the fixed pipe far from the center of the housing. A cutting driving assembly is arranged on the front side wall of the cutting roller. A discharging assembly is arranged below the housing.

[0006] In some embodiments, the cutting driving assembly includes a main shaft. The centers of the front side walls of the two cutting rollers are fixedly connected with the main shaft respectively. The main shaft penetrates through the front side wall of the housing and is fixedly connected with a first gear. The main shaft is movably connected with the housing. Two second gears meshing with each other are arranged between the two first gears. The center of the side wall of the second gear is movably connected with a circular shaft. The circular shaft is fixedly connected with the housing. The two second gears are respectively meshed with the adjacent first gears. A mounting plate is fixedly connected to the front side wall of the housing. One of the main shafts penetrates through the mounting plate and is fixedly connected with a driving motor. The driving motor is fixedly connected with the mounting plate.

[0007] In some embodiments, the discharging assembly includes a discharging housing sleeved on the bottom surface of the outer housing. Fixed plates are fixedly connected to the left and right side walls of the outer housing. A vertical rod is movably connected to the fixed plates. One end of the vertical rod is fixedly connected to a top plate and the other end is fixedly connected to the discharging housing. A spring is sleeved on the vertical rod, and the two ends of the spring are respectively fixedly connected to the fixed plate and the discharging housing. Vibration motors are fixedly connected to the front and rear side walls of the discharging housing.

[0008] In some embodiments, the upper and lower side walls of the discharging housing are both rectangularly arranged, and the length and width of the top surface of the discharging housing are larger than those of its bottom surface.

[0009] In some embodiments, a plurality of support rods are evenly distributed and fixedly connected to the outer side wall of the outer housing, and the support rods are arranged in an inverted L shape.

[0010] In some embodiments, through holes are formed in the left and right side walls of the outer housing, and metal meshes are fixedly installed in the through holes.

[0011] In some embodiments, an annular groove is formed near the rear side in the inner cavity of the circular groove. An annular plate is fixedly connected to the outer side wall of the fixed pipe, and the annular plate is movably connected to the annular groove.

[0012] Through the above solution, by connecting the fixed pipe to an external cold air filling device, the granulation operation of the plastic is realized by the rotation of the two cutting rollers. And when the cutting of the plastic by the cutting rollers is completed and the cutting rollers rotate to positions close to both sides of the inner cavity of the outer housing, at this time, the first through hole and the second through hole are communicated, and the cold air flow in the inner cavity of the fixed pipe is sprayed out from the cutting rollers through the first through hole and the second through hole. On the one hand, the cold air flow can blow out the particles stuck on the cutting rollers, which is convenient for processing and use. On the other hand, it can realize the cooling operation of the cutting rollers, further improving the efficiency of the granulation process; by starting the vibration motor, the vibration motor applies a vibration force to the discharging housing. The movement of the discharging housing can make the vertical rod move on the fixed rod, and the continuous deformation of the spring can realize the convenient discharge of the plastic particles after granulation in the inner cavity of the discharging housing, effectively improving the efficiency of the granulation process of the plastic particles.
