The present utility model provides a counter-rotating twin-screw extruder for plastic pellet processing, which relates to the technical field of plastic pellet production equipment, and comprises a mounting plate. A heat transfer chamber is installed on the left side of the top wall of the mounting plate, and a temperature regulation assembly is installed on the side of the heat transfer chamber. With the cooperation of the temperature regulation assembly, when the heat transfer chamber receives the temperature change during the operation on the plastic pellet melt inside the transmission chamber and the joint connector, the present utility model can compare the set temperature value and the actually detected temperature value with the preset temperature threshold, convert the temperature signal into an electrical signal and transmit it to two control circuits respectively, so as to start the resistance wire heater or the cooler, and control the ambient temperature within a small error range. This avoids the problem that the excessively high or low material temperature causes air bubbles inside the plastic melt during the extrusion process, which may lead to voids inside the extruded plastic pellets, and ensures the product processing quality.
