[0029] A pressure detector 23 is fixedly disposed on the rear wall of the detection cavity 24 , and the pressure detector 23 can detect the magnitude of the pressure and transmit information.

[0030] A safety spring 25 is fixedly connected between an end surface of the pressure detector 23 close to the connecting rotating rod 20 on the same side and an outer circumferential surface of the connecting rotating rod 20 located in the detection cavity 24 .

[0031] A rotating motor 17 is fixedly disposed on the right side of the upper end surface of the frame 11 , and the right end surface of the power shaft 16 is dynamically connected to the rotating motor 17 .

[0032] A plurality of heating rollers 13 are fixedly disposed on the side wall of the injection cavity 21 , and the heating rollers 13 can play a heating role after being energized.

[0033] A control panel 18 is fixedly disposed on the rear side of the right end surface of the frame 11 , and the control panel 18 can control the start and stop of all motors of the utility model.

[0034] Specific workflow:

[0035] During the injection molding process, after injecting the molten plastic from the outside into the feed port 14, the heating roller 13 and the rotating motor 17 are started at the same time. The heating roller 13 starts to heat the injection cavity 21, so that the injection cavity 21 is at a higher temperature. At the same time, the rotating motor 17 starts to drive the power shaft 16 to rotate, thereby driving the connecting rotating rod 20 to rotate. At this time, the safety spring 25 begins to shrink initially under the force, and the pressure detector 23 begins to detect the extrusion force exerted on the safety spring 25, and drives the buffer outer shaft 15 to rotate, thereby driving the injection roller 22 to start rotating. At this time, the safety spring 25 has not reached the force limit. As the injection roller 22 rotates, the plastic solution in the injection cavity 21 can be pushed to the left and squeezed out through the outlet 19.

[0036] If there is unmelted solid plastic inside the plastic in the injection molding cavity 21, as the injection molding roller 22 rotates, the solid plastic will collide and squeeze with the surface of the injection molding roller 22, making the injection molding roller 22 unable to rotate. At this time, the pressure on the safety spring 25 increases and is detected by the pressure detector 23. The pressure detector 23 will send an abnormal information to the control panel 18, and the control panel 18 will control the rotating motor 17 to stop or reverse, to ensure that the solid plastic is completely melted under the heating of the heating roller 13 in the injection molding cavity 21, and then start the rotating motor 17 in the forward direction to start normal operation. The utility model detects the rotation pressure of the injection molding roller 22 in real time. When the injection molding roller 22 cannot rotate normally due to the squeezing of solid plastic, it can stop working immediately, thereby preventing the injection molding roller 22 from being damaged and increasing the service life of the injection molding roller 22.

[0037] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
