Description

Technical Field

[0001] This utility model relates to the technical field of packaging bottle production, and in particular to an extrusion device for packaging bottle production. Background Technology

[0002] With the rapid development of the cosmetics industry, the requirements for the appearance, dimensional accuracy and production efficiency of packaging bottles are constantly increasing. Traditional extrusion equipment has problems such as unstable temperature control, poor mold adaptability and low degree of automation, making it difficult to meet the diversified and personalized packaging needs. Moreover, the production efficiency and yield are limited, so there is an urgent need to develop more advanced and efficient extrusion equipment for cosmetic packaging bottle production.

[0003] In existing technologies, extrusion blow molding equipment is used. First, plastic raw materials are added to the extruder. Through heating and the rotation of the screw, the plastic raw materials are melted and plasticized in the barrel. Then, the molten plastic is extruded into a tubular preform. The preform hangs between the two halves of the blow molding die. Next, the die closes to clamp the preform. At the same time, compressed air is introduced from the air inlet of the die, causing the preform to expand inside the die and conform to the inner wall of the die, forming the same shape as the die cavity. Finally, after cooling and solidification, the die is opened and the formed packaging bottle is taken out.

[0004] However, in the existing extrusion equipment used for packaging bottle production, plastic raw materials are continuously added into the barrel during use. During the mixing process, unmelted plastic raw materials are mixed with melted plastic raw materials, which makes the extrusion nozzle easily blocked by unmelted plastic particles, thus affecting the normal extrusion operation.
