Injection and rolling nozzle for high-polymer forming by continuous injection and continuous rolling

The invention discloses an injection and rolling nozzle capable of enabling a high-polymer plastic injection machine and a plastic rolling machine to form continuous injection and continuous rolling. The injection and rolling nozzle comprises an input mechanism, an output mechanism and a main body, wherein the input mechanism is in sealing connection with a spraying nozzle of the plastic injection machine and receives molten materials; a sealing cavity is formed between the output mechanism and a roll surface of a roll of the rolling machine and injects the molten materials to the cavity; the main body is connected with the input mechanism and the output mechanism and forms a sealed whole body by an upper copper core block and a lower copper core block in an overlapping mode; and a flowing channel structure for conveying the molten materials is arranged in the sealed whole body. The injection and rolling nozzle disclosed by the invention has the advantages that the new process for continuous injection and continuous rolling of high polymer can be realized, forward-backward expansion and rotary adjustment of the position of the injection and rolling nozzle can be realized, the mold locking force can be borne, the flow-speed uniformity of the width direction of an outlet of the injection nozzle, the uniformity of the temperature field and the insulating characteristic of the whole device can be realized, and by the continuous injection and continuous rolling process and in the sealing cavity formed between the input mechanism and the roll surface of the roll of the rolling machine, the state of the high polymer is changed into a viscous state when the high polymer passes through the input mechanism, a high-elasticity state when the rolling is started and a glass state when the high polymer passes through a rolling outlet.
