Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch, in particular to a plastic masterbatch granulator. Background Art

[0002] Plastic masterbatch is a concentrate made by loading an abnormal amount of plastic additives into the resin. When manufacturing plastic products, it is not necessary to add the plastic additives. Instead, it is only necessary to add the abnormal amount of masterbatch in proportion. Therefore, plastic masterbatch is a new type of special material for processing polymer materials. In the production process of plastic masterbatch, a granulator is required. When using existing small granulators, most people will install a water tank under the discharge port to quickly cool the masterbatch to prevent the masterbatch from sticking together. However, when the masterbatch falls into the water tank, most of them are stacked together and still stick together. In addition, most existing granulators do not have a screening function. After the masterbatch is cooled, a screening device must be used to pick out the unqualified masterbatch. This results in the unqualified masterbatch having a wet surface when it is recycled and reused. The masterbatch needs to be dried before it can be reused, which is a more cumbersome operation.

[0003] After searching, the prior art has an authorization announcement number of CN214605296U, which discloses a plastic masterbatch pelletizing machine, comprising a machine body, an electric motor fixedly connected to the upper end of the machine body, an output shaft of the electric motor passing through the machine body and a rotating rod fixedly connected to the lower end, and a forming disk, a rotating plate, a cutting plate and other devices are provided to make the manufactured plastic pellets similar in shape and size, which is convenient for measurement.

[0004] The above patent does not have a water tank cooling structure when in use, cannot ensure that the masterbatch will not stick together, and cannot screen unqualified masterbatch, so the subsequent recovery and reuse of the masterbatch is more cumbersome; therefore, we need to propose a plastic masterbatch granulator.
