Circulating cooling device capable of preventing plastic particle sticking

Abstract

The invention discloses a circulating cooling device capable of preventing plastic particle sticking. An inner casing is arranged in a material cylinder. A material guide passage passes through the interior of the inner casing from top to bottom. The outer side wall of the inner casing is fixedly connected to the inner side wall of the material cylinder through a connection rod. The top and bottomof the inner casing and the top and the bottom of the material cylinder form gaps. A rotating shaft is vertically disposed in the material guide passage. Two ends of the rotating shaft are rotatinglyconnected to the top and bottom of the material cylinder. A circulating water passage passes through the interior of the rotating shaft along the center line. The rotating shaft is sleeved by a driven gear. An output shaft of a driving motor is provided with a driving gear. The driving gear is meshed with the driven gear. The rotating shaft is provided with a spiral blade. The top and bottom of the rotating shaft are respectively provided with rotary joints. Through movement of the spiral blade, the spiral blade drives the plastic particles to continuously flip and rise so that the adhesion between the plastic particles is prevented and the circulation movement of the plastic particles is promoted. The plastic particles can be fully and uniformly cooled.

Description

technical field [0001] The invention relates to the field of plastic production and processing equipment, in particular to a circulating cooling device capable of preventing plastic particles from sticking. Background technique [0002] After the plastic is melted, extruded, drawn, and pelletized, the plastic particles still have a certain temperature. At this time, the plastic particles are prone to bonding, which affects the subsequent processing and use of the plastic particles. Therefore, the plastic particles need to be cooled. At present, in the cooling process of plastic particles, when the total number of plastic particles is large, there are problems such as insufficient cooling of particles and uneven cooling temperature, resulting in inconsistent particle sizes. Second, it is difficult to prevent bonding between plastic particles during the cooling process. Contents of the invention [0003] In view of the technical problems mentioned above, the object of the p...
