Description

Technical Field

[0001] This utility model relates to the technical field of plastic masterbatch molding equipment, and in particular to a molding equipment for plastic masterbatch. Background Technology

[0002] Plastic masterbatch is a key additive carrier in plastic processing. It is made by mixing excessive amounts of chemical additives, carrier resins, and dispersants in a high concentration. The core function of plastic masterbatch molding equipment in production is to realize the process flow of raw material mixing, melting and plasticizing, dispersion and homogenization, granulation and shaping, and screening. Appropriate equipment needs to be selected according to the composition, output requirements, and particle morphology of the masterbatch. Traditionally, after plastic masterbatch is granulated by a granulator, it needs to be screened by a screening device to ensure the quality of the plastic masterbatch. For example, Chinese patent discloses a molding equipment for plastic masterbatch (authorization announcement number CN220129221U). This patented technology uses the meshing of active teeth and toothed rings to make the sorting disc rotate and screen the plastic masterbatch in the screening barrel. At the same time, the rotating shaft drives the arc plate to rotate through the synchronous rod, thereby preventing the plastic masterbatch from clogging during screening. The arc plate will cut unqualified plastic masterbatch and discharge it from the screening barrel through the discharge port, preventing unqualified plastic masterbatch from clogging the sorting disc and improving the screening efficiency. However, existing publicly available plastic masterbatch molding equipment still has some shortcomings in practical applications that need improvement, such as: Plastic masterbatch material is formed by melting and stretching, and it retains residual heat. After being granulated by the cutter, there will be adhesion problems. If it is directly screened, small plastic masterbatch particles will be discharged along with large plastic masterbatch particles, which is not conducive to the screening effect. In addition, the dust generated during the cutting process adheres to the surface of the plastic masterbatch and is screened out, requiring subsequent screening to remove dust, which is not conducive to the processing efficiency of plastic masterbatch. Furthermore, the dust drift affects the cleanliness of the processing area. Relying solely on arc-shaped plate stirring for screening results in a low screening speed, which easily leads to the accumulation of plastic masterbatch, affecting the completeness of screening and hindering the processing efficiency of plastic masterbatch. Therefore, those skilled in the art have provided a molding device for plastic masterbatch to solve the problems mentioned in the background art. Utility Model Content
