Double-wall corrugated pipe extruder suitable for high-speed production

Technical Field

The utility model relates to a double-walled bellows extruder especially relates to a double-walled bellows extruder suitable for high-speed production line.

Background

The double-wall corrugated pipe is a novel pipe with corrugated outer wall and smooth inner wall. It has been widely used as a buried drain pipe, an underground cable pipe, etc. in a considerable range to replace conventional cast iron pipes, cement pipes, general plastic pipes, and wound corrugated pipes. At present, the main varieties of the double-wall corrugated pipe are polyvinyl chloride (PVC), high-density polyethylene (HDPE) and rigid polyvinyl chloride (PVC-U).

The double-wall corrugated pipe production process is characterized in that materials are extruded to an extrusion die from an extruder in a molten state, the extrusion die changes the rod-shaped materials into circular rings and extrudes the circular rings to a forming module, the materials are formed under the constraints of the forming module (the outer wall is tightly attached to the outer wall of the forming module for forming through vacuumizing) and a water jacket (the inner wall of a cooling tank for forming), the formed double-wall corrugated pipe is continuously conveyed forwards, the corrugated pipe passes through the cooling water tank and is conveyed to a cutting machine, and the cutting machine cuts out the corrugated pipe meeting the technical requirements according to.

The existing extruder occupies a large space, is not suitable for a high-speed production line, and sometimes has the condition that raw material plasticization is poor to influence the quality of the corrugated pipe. The machine barrel expands when heated to generate displacement, and the gravity center of the extruder changes in the production process, so that the extruder stops working. There is an urgent need for a double-wall corrugated pipe extruder that can be adapted for high-speed production lines.

Detailed Description

A double-walled bellows extruder suitable for high-speed production is further described below with reference to the accompanying drawings.

The double-wall corrugated pipe extruder suitable for high-speed production comprises a machine barrel 1 and a machine head connector 2 which are fixedly connected, a hopper 3 is positioned at a feed port of the extruder, the machine barrel 1 is fixed on a base 5 through a bracket 4, the machine barrel 1 and the bracket 4 are connected by a pressing block, the displacement caused by the thermal expansion of the machine barrel can be counteracted, the stability of a system is improved, the feed port is positioned at one end of the machine barrel 1, a pure material screw 6 is arranged in the machine barrel 1, one end of the pure material screw 6 is connected with a high-torque speed reducer, the other end of the pure material screw 6 is positioned at a discharge port of the machine barrel 1, a barrier head 9 is arranged between the pure material screw 6 and the extruder head, the pure material screw 6 is connected with the speed reducer through a spline, the stability of the connection of the pure material screw 6 and the speed reducer is improved, the motor 7 with small volume and large torque is adopted, and the motor 7 is arranged below the machine barrel 1, so that the extruder is compact in structure and occupies a minimum space.
