According to a preferable technical scheme, cooling gas is filled in the interlayer, the lower end of the interlayer is connected with an air compressor, and the top of the interlayer is provided with an exhaust hole. Because the material in the hopper is high-molecular granules, the temperature is increased in the process of friction between the granules and the hopper wall, on one hand, the flowing of the granules is influenced, and on the other hand, the quality of the granules is damaged, and therefore, a cooling system is added in the hopper according to the characteristics of the granules.

As the preferred technical scheme, the upper end of the supporting rod is connected with the supporting frame, the upper end of the supporting rod is provided with a motor for driving the supporting rod to rotate, and the guide plate is made of semi-rigid materials.

The rotation of guide plate drives the aggregate to rotate, has improved the homogeneity that the aggregate mixes.

Preferably, the guide plate is positioned at a vertical distance 1/3-1/4 from the opening of the hopper chamber. The guide plate is located 1/3 ~ 1/4 of hopper, and the granule is poured on the guide plate and is got into in the groove wall of pouring the material through the bounce-back, increases the mobility of granule, if the guide plate position is too high, can lead to the granule to pop out the hopper, causes the loss of granule.

As the preferred technical scheme, a fixing piece is arranged at the position, located at the opening of the hopper chamber, of the position outside the hopper chamber, and the fixing piece is rotatably connected with the supporting frame.

As a preferred technical scheme, an anti-collision rubber strip or a spring buffer is arranged at the contact position of the support frame and the hopper. Prevent that the hopper from striking the support frame in the vibration process, long-time striking reduces the intensity of support frame.

As a preferred technical scheme, the included angle between the guide plate and the horizontal plane is 60 degrees, and the edge of the guide plate is a smooth curved surface. Increasing the slope at the discharge nozzle facilitates rapid pellet discharge.

The utility model has the advantages and the beneficial effects that: the blanking hopper provided by the utility model enables the material blanking to be more uniform, and the product quality is obviously improved; and the feeding hopper enables the granules to keep the original semi-finished product state and enter the extruding machine, so that the product is stable.
