[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an extruder particle weighing device, comprising an extruder body, a weighing mechanism is arranged outside the extruder body, and an adjusting mechanism is arranged outside the weighing mechanism;

[0007] The weighing mechanism includes a weighing plate, a weighing sensor is installed at one end of the weighing plate, a controller is installed at one end of the weighing sensor, an electric telescopic rod is fixedly connected to the inner side of the weighing plate, a push plate is fixedly connected to one end of the electric telescopic rod, and a conveying assembly is arranged on the top of the weighing plate.

[0008] Preferably, the conveying assembly includes an auger, and the bottom of the auger is fixedly connected to a discharge pipe.

[0009] Preferably, the auger is installed at one end of the extruder body, and the discharge pipe is arranged on the top of the weighing plate.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model sets the auger at the extrusion head of the extruder body so that the extruded material can directly fall into the inside of the auger, and then starts the auger to drive the material to move toward the weighing plate. The auger can adjust the discharge speed so that the material falls from the discharge pipe into the adjustment shell. Through the setting of two adjustment plates, the distance between the end pieces of the two adjustment plates is the coarseness of the material, so that the material can only fall onto the weighing plate one by one. After the material falls onto the weighing plate, the weighing sensor detects the weight. When the detected weight is qualified, the controller starts an electric telescopic rod, so that the electric telescopic rod drives the push plate to push the material out of the through hole of the weighing plate, and a collection box is set there for collection. When the detected weight is unqualified, the controller starts another electric telescopic rod, so that the push plate at the end of the electric telescopic rod pushes the material out of another through hole, and a collection box is also set there for collection, thereby completing the weighing operation and achieving the effect of individually weighing the material and improving the detection accuracy.

[0016] Secondly, the utility model can drive the adjustment plate to rotate by rotating the damping shaft inside the adjustment block according to the coarseness of the extruded material, thereby adjusting the distance between the two adjustment plates so that the distance between the end points of the two adjustment plates is consistent with the coarseness of the extruded material, completing the operation of adjusting the coarseness and achieving the effect of adjusting according to the coarseness of the material.
