Description

Technical Field

[0001] The utility model belongs to the technical field of pelletizers, and particularly relates to a pelletizer that is convenient for heat dissipation. Background Art

[0002] A pelletizer is a widely used device in industrial production. Its main function is to cut various materials into particles of specific size and shape. The working principle of a pelletizer is usually to cut and separate continuous materials with the help of rotating knives or cutting parts. These materials include plastics, rubber, fiber, food, etc. In the plastic processing industry, pelletizers are often used to cut extruded plastic strips or plastic sheets into uniform plastic particles, which is very helpful for subsequent packaging, transportation and further processing.

[0003] The Chinese patent with the publication number of "CN209425954U" discloses a pelletizer with convenient heat dissipation, which includes a pelletizer body and a storage barrel. The storage barrel includes a circular shell, and a partition is vertically arranged inside the shell. The partition divides the inner cavity of the shell into a heat dissipation area and a discharge area. The bottom of the shell is equipped with a first driving mechanism, and the shell is also provided with a stirring mechanism. The stirring mechanism consists of a stirring shaft and a circular stirring blade. The top of the shell is provided with a second driving mechanism. The partition is provided with a through groove adapted to the circular stirring blade at a position corresponding to the circular stirring blade. The partition in the utility model can achieve heat dissipation while discharging, and separate the masterbatch just discharged from the masterbatch that has been dissipated. The stirring mechanism stirs the masterbatch, which can make the masterbatch dissipate heat faster, which effectively solves the problem of waiting for the temperature of the pellets to drop before packaging, thereby achieving continuous and rapid packaging of the pellets, greatly improving work efficiency;

[0004] However, during the use of the above-mentioned equipment, although a stirring mechanism is used in conjunction with a heat dissipation mechanism to assist in stirring and dissipating heat, there are still certain defects and shortcomings in the specific application process. First, during its use, the stirring structure is relatively simple, and the material cannot be caused to roll up and down quickly and efficiently during the stirring process. It is difficult to cause the heat dissipation air to contact the material quickly and evenly as a whole. At the same time, during its heat dissipation process, it is obvious that the hot air generated by the heat dissipation will contain more harmful substances. If some plastics, rubbers or other chemical materials containing volatile organic compounds (VOCs) are being processed, then during the pelletizing process, due to friction, heating and other effects, harmful gases such as benzene, formaldehyde, vinyl chloride, etc. will be released. It can be seen that the above-mentioned equipment will obviously cause a certain degree of harm to the environment during the processing process, so it is necessary to improve the existing technical means.

The rotation of the rotating shaft 542 can drive the stirring plate 543 to rotate. As the stirring plate 543 rotates, the material that is rolling upwards by the auger 541 can be further stirred. In this process, by starting the driving motor 533 to run forward and reverse, the material can be assisted to roll up and down more evenly, so that the material can be efficiently in contact with the air, which can improve the overall heat dissipation efficiency of the device and enable the device to dissipate heat quickly and efficiently.
