Description

Technical Field

[0001] This utility model relates to the field of extruder barrel technology, specifically a split barrel for a conical twin extruder. Background Technology

[0002] Currently, conventional conical twin-screw extruders use an integral structure for their barrels, meaning the barrel is machined as a single unit. The internal cavity is machined to house the screw in an "∞" shape. Machining the cavity requires a specialized machine tool, which is slow and costly to drill holes in the barrel. Alternatively, the barrel can be cast, but casting results in a low yield, indirectly increasing the manufacturing cost of the barrel.

[0003] Authorization announcement number CN221497040U discloses a split barrel for a conical twin-screw extruder. This patented technology utilizes two partially overlapping semicircular grooves, number one and number two, which can be processed separately using ordinary machine tools, eliminating the need for specialized machine tools. After processing, the upper and lower barrels are connected by a connector. The two partially overlapping semicircular grooves, number one and number two, cooperate to form an "∞"-shaped inner cavity, effectively reducing processing difficulty, improving processing efficiency, and lowering manufacturing costs, which can be reduced by more than half. Furthermore, when the inner cavity of the barrel wears out, the barrel can be disassembled for further processing. The wear surface is easy to repair, the rework cost of the barrel is extremely low, and the number of repairs after wear is unlimited. However, in this solution, when the overlapping first and second semicircular grooves are matched to form an "∞" shape, the method used is to use a threaded rod and nut as a fixing part. In contact measurement, the threaded gauge is prone to wear, which affects the installation accuracy and the cost of replacing the gauge is also high. Furthermore, this patent does not take specific measures to seal the combined barrel, which leads to the unqualified finished product of the split barrel. Therefore, a split barrel for conical twin extruder is needed to improve the above problems. Utility Model Content

[0004] To address the problems in existing solutions where threaded rods and nuts are used as fixing components when overlapping semicircular grooves 1 and 2 are fitted together to form an "∞" shape, the threaded gauges are prone to wear during contact measurement, affecting installation accuracy and increasing the cost of replacing the gauges. Furthermore, the patent does not take specific measures to seal the merged barrel, resulting in substandard finished products from split barrels. The purpose of this invention is to provide a split barrel for a conical twin extruder to solve the problems mentioned in the background.

The semi-circular rubber sealing strip can withstand friction and vibration under dynamic working conditions, and has good wear resistance and fatigue resistance, thereby extending the service life of the seal. Compared with some high-performance sealing materials, the manufacturing cost of the semi-circular rubber sealing strip is relatively low, making it an economical choice. Attached Figure Description
