Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mixing and cooling devices, in particular to a mixing and cooling device. BACKGROUND

[0002] Plastic particle mixture is an important raw material for manufacturing plastic products such as toys and daily necessities. The uniformity of the mixture and the temperature control directly affect the quality and performance of the final product. During the mixing process of plastic particles, a mixing device is usually used to uniformly mix different types of plastic particles, additives, etc. However, the friction between the stirring blades and the raw materials during the mixing process generates heat, causing the temperature of the mixture to rise. Excessive temperature not only may cause thermal degradation of the plastic particles, affecting their physical properties, but also may prolong the production cycle and reduce the production efficiency. Therefore, how to effectively control the temperature during the mixing process has become a key technical problem in the mixing process of plastic particles.

[0003] Currently, the production of plastic particle mixture mainly relies on a mixer, which typically includes a mixing barrel and electric stirring blades. The stirring blades rotate at high speed under the drive of the motor to fully mix the plastic particles and additives. However, this structure has obvious limitations: as the stirring time increases, the friction between the blades and the raw materials generates a large amount of heat, causing the temperature of the mixture to gradually rise. When the temperature reaches a certain threshold, the stirring must be stopped, and the production must be continued after the mixture is naturally cooled to a safe temperature.

[0004] The existing mixer structure lacks an effective cooling mechanism and cannot control the temperature of the mixture in real time during stirring. The heat generated by the friction between the stirring blades and the raw materials accumulates, causing the temperature to rise, forcing the production process to be interrupted to wait for natural cooling. This cooling method is inefficient and seriously affects the production efficiency and the stability of product quality. CONTENT OF THE INVENTION
