Preferably, the driven disc 9 is made of rubber for achieving buffering and vibration reduction.

The rubber texture is comparatively soft, can reduce the impact force that produces when driven plate 9 and driving-disc 8 laminate, has realized buffering and damping.

During the use of the device, the bottom end of the feeding pipe 2 is connected with an external heating extrusion device, when raw materials are put into the hopper 1, the raw materials can enter the heating extrusion device from the feeding pipe 2, in addition, the driving motor 6 is started, the driving disc 8 is driven by the driving shaft 7 to rotate, the driving disc 8 drives the driven disc 9 to rotate through the guide rod 11, the rotating disc 5 is driven by the rotating disc 9 to rotate, the rotating stirring rod of the rotating disc 5 rotates, in addition, the rotation of the driving shaft 7 enables the air pressure in the fixed box 3 to reciprocate up and down through the pressure regulating unit, when the air pressure in the fixed box 3 is increased, the driven disc 9 can move downwards under the action of the air pressure, when the air pressure in the fixed box 3 is increased, the driven disc 9 rises through the action of the air pressure to realize the reset of the rotating shaft, the reciprocating lifting of the driven disc 9 can be realized, the reciprocating lifting of the driven disc 9 drives the rotating disc 5 and the auxiliary rod 30 to reciprocate through the air pressure 4, during the descending of the auxiliary rod 30, the auxiliary rod 30 can be inserted into the feeding pipe 2, so that the raw material in the feeding pipe 2 can be extruded and moved downwards to prevent the feeding pipe 2 from being blocked, and the function of stirring the raw material can be realized through the rotation of the auxiliary rod 30, so that the uniformity of the distribution of the raw material can be improved, here, during the reciprocating ascending and descending of the driven disc 9, the raw material can be intercepted through the first filter screen 1613 to prevent the raw material from entering the fixed box 3, and the rotation of the rotating disc 5 drives the fan blades 19 to rotate through the connecting shaft 18, the rotation of the connecting shaft 18 also enables the fixed rod 21 to drive the sealing ring 20 to ascend through the transmission unit, and the sealing ring 20 is separated from the through hole, at this time, through the rotation of the fan blades 19, the air in the connecting pipe 14 can be discharged from the circular hole, the air in the hopper 1 enters the connecting pipe 14 from the through hole, and under the action of the air flow, the dust in the raw material can pass through the screen 16 to enter the connecting pipe 14, and realize holding back the raw materials through screen cloth 16, simultaneously, can hold back the dust through second filter screen 17, when axis of rotation 4 stall, at this moment, make sealing ring 20 descend through the drive unit and realize reseing, can so that sealing ring 20 blocks up the through-hole, prevents that the dust that holds back on the second filter screen 17 from taking place to leak.

Compared with the prior art, this an injection moulding equipment for wire and cable production has realized preventing the function of jam through complementary unit, compares with current complementary unit, and this complementary unit can also realize the function of stirring the raw materials, and the practicality is stronger, not only, has still realized the function of collecting the dust in the raw materials through album dirt mechanism, compares with current collection dirt mechanism, and this collection dirt mechanism can also prevent that the dust of collecting from taking place to leak, and the practicality is stronger.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
