When the two pairs of rollers 2 rotate, the raw materials between the two pairs of rollers 2 are extruded by the two pairs of rollers 2, and the raw materials between the left pair of rollers 2 and the pushing block 3 are extruded by the two pairs of rollers 2 to plasticate the raw materials.

After plastication begins, the raw materials begin to be agglomerated after being sticky, at the moment, the detection driving part is manually started, the detection driving part drives the roller shaft 5 to rotate clockwise, when the opening of the accommodating groove 51 faces to the left, the sealing plate 53 is manually released, the sealing plate 53 presses the left wall of the heating cavity 52 under the action of the pressure spring 55 to shield the through hole, the raw materials move to the position opposite to the accommodating groove 51 and then enter the accommodating groove 51, when the accommodating groove 51 rotates to the opening facing to the upper side, under the condition of high raw material stickiness, the raw materials in the accommodating groove 51 are adhered to the raw materials adhered to the roller pair 2, when the raw materials on the roller pair 2 move upwards relative to the roller shaft 5, the raw materials in the accommodating groove 51 are driven to move upwards, so that a large amount of raw materials are not remained in the accommodating groove 51, and when the roller shaft 5 continues to rotate, the accommodating groove 51 is shielded by the outer wall of the sleeve, when the holding tank 51 is rotated between the infrared ray generator and the infrared ray receiver, the infrared ray emitted from the infrared ray generator is not blocked by the raw material. And when the viscidity of raw materials is relatively poor, the raw materials in the holding tank 51 can't fall out, can shelter from the infrared ray, and artifical accessible infrared receiver's testing result judges viscidity. When the viscosity is higher, the discharge hole is opened again to detect the viscosity of the raw materials, so that the detection frequency can be reduced. In the case of poor viscosity, when the holding tank 51 is rotated again until the opening faces upward, the sealing plate 53 is pressed downward, so that the hot air flows upward from the through hole, and the granular raw material is blown upward and enters between the pair of rolls 2 again, so that the raw material can continue to be plasticated.
