Production line of modified plastic granules

Abstract

The invention discloses a production line of modified plastic granules, belonging to the technical field of plastic machine manufacture. The production line comprises a mixing feeder, an extruder, a cooling water tank, a drying fan, a traction dicing cutter and a packaging machine which are connected in sequence, and an electric control cabinet connected with all the devices, wherein a dustproof cover is arranged at a feeding hole of the mixing feeder; a smoke-proof cover is defined at the periphery of a heating unit of the extruder; a smoke discharge hole of the smoke-proof cover is connected with a heat exchange device by an exhaust fan; the heat exchange device is connected with the drying fan by a heated end outlet; the tail end of the heating unit is connected with a die head main body comprising an internal filter screen replacement plate; the die head main body is internally provided with a sensor which is connected with the electric control cabinet and is capable of removing the filter screen replacement plate from the die head main body by a cylinder; a plurality of water inlets and a plurality of water outlets are formed in the two opposite side walls of the cooling water tank, respectively. The problems that the environment is polluted, the production is influenced after a filter screen of a die head of the extruder is blocked and the performance of plastic finished products is influenced by the non-uniform temperature of water in the cooling water tank can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic machinery manufacturing, in particular to a modified plastic particle production line. Background technique [0002] At present, in the production of modified plastic materials, granular raw materials are produced on the modified plastic granule production line. It is composed of electrical control cabinets connected with each equipment; the production line process is: mixing feeder → extruder → cooling water tank → drying fan → traction device → pelletizer → packaging machine. This kind of production line will produce in the production process: 1. The dust generated by the stirring feeder during feeding and the flue gas generated by the heating unit of the plastic extruder will pollute the air environment and endanger human health; 2. Filter If the net is not replaced in time after it is blocked, it is easy to cause damage to the machine, thereby affecting production; 3. The temperature of the w...
