Benefits of technology

The technical effect of this new design is how it allows excessive liquid (molten) collateral fluid or other substances generated during manufacturing processes to recycle back into the process without causing damage or contamination. This helps save resources while improving production efficiency.

Problems solved by technology

The technical problem addressed in this patented text relates how to prevent leaks that occur during high-pressure injection processes caused by excessive meltdroplet movement within an injection plumping rod used with current systems due to poor sealing design on these parts.

Abstract

The invention discloses a glue injection plunger head and a glue injection device. The glue injection plunger head comprises a plunger main body part, wherein the outer peripheral wall of the plungermain body part is suitable for sliding fit with the inner peripheral wall of the material storage cylinder. An accommodating groove is arranged on the outer peripheral wall of the plunger main body part; the plunger body part is internally provided with a central hole and at least one first channel which is connected between the central hole and the accommodating groove; a moving plunger part, thefirst end of the moving plunger part is provided with a guide column extending into the central hole; the second end of the moving plunger part is adapted to be connected to a retractable plunger rod; a limit element arranged at one end of the plunger main body part, adjacent to the moving plunger part; the outer peripheral wall of the plunger main body part is provided with an air guide groove communicated with the accommodating groove. The glue injection plunger head can recover the molten colloid material leaked from the gap between the plunger head and the cylinder wall for secondary glueinjection, so that the leakage of the molten colloid material can be effectively reduced, and the utilization rate of the raw material is improved.
