Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a die head for a pellet extruder. Background Technology

[0002] Extruders are a type of plastics machinery, originating in the 18th century. Based on the angle between the material flow direction at the die head and the screw centerline, extruders can be classified into right-angle die heads and angled die heads, among others. Screw extruders rely on the pressure and shear force generated by the rotating screw to fully plasticize and uniformly mix the material, which is then shaped through a die. Plastic extruders can be broadly classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.

[0003] The existing pellet extruder die head replacement is inconvenient and requires manual operation by staff. Furthermore, manual disassembly is also required when cleaning the inside of the extruder. Utility Model Content

[0016] Preferably, the fixing assembly on the connector head includes a bidirectional electric cylinder, and the output end of the bidirectional electric cylinder is provided with a fixing member.

[0017] By adopting the above technical solution, the retraction of the output end of the bidirectional electric cylinder can drive the fixing part away from the connector, while the output end of the bidirectional electric cylinder drives the fixing part closer to the connector, thus assisting in the installation and disassembly of the mold head.

[0018] Preferably, connectors are provided on both sides of the connector, and the bidirectional electric cylinder is provided on both sides of the connector through the connectors.

[0019] By adopting the above technical solution, the bidirectional electric cylinder is stably and securely installed on the connector head through the connector, which can prevent the fixed components from shifting during use.

[0020] Preferably, the fixing member has a fixing head inside, and the top and bottom of the mold head and the connector are provided with fixing holes. The size of the fixing head on the fixing member is adapted to the size of the fixing holes on the mold head and the connector. The fixing member is engaged with the mold head and the connector through the fixing head and the fixing holes.

If the fixing component is damaged, the user can manually disassemble the connector 6 from the main body 1, which facilitates the maintenance of the fixing component.

[0040] Working principle: If the user needs to replace the die head 9 or clean the inside of the extruder, the user can activate the bidirectional electric cylinder 7 to move the fixing part 8 away from the connector head 6, causing the fixing head on the fixing part 8 to disengage from the fixing hole on the die head 9. Then the user can remove the die head 9 from the connector head 6 and disassemble the die head 9 from the main body 1, making it easier to clean the inside of the main body 1. The user can also use the output end of the bidirectional electric cylinder 7 to move the fixing part 8 closer to the connector head 6, allowing the fixing head on the fixing part 8 to enter the fixing hole on the die head 9, thus ensuring that the die head 9 can be stably and securely installed on the connector head 6, enabling quick replacement of the die head 9. If the fixing component is damaged, the user can manually disassemble the connector head 6 from the main body 1 for easy maintenance of the fixing component. The user can also manually disassemble the connector head 6 from the main body 1 to facilitate cleaning the inside of the main body 1.
