Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE pipe processing technology, specifically a PE pipe extruder. Background Technology
[0002] An extruder is an important piece of machinery in plastic processing and molding, typically consisting of a transmission device, feeding device, barrel, screw, die head, and mold. Plastic material enters the extruder through the feeding device and is conveyed forward by the rotating screw. During this forward movement, the material is heated by the barrel and sheared and compressed by the screw, melting and undergoing a transformation from a glassy state to a highly elastic state and then to a viscous flow state. This viscous flow material is then conveyed to the die head by the screw, and further processed through the mold mounted on the die head. In the mold, the viscous flow material cools and solidifies before leaving the extruder, forming the desired part. Based on the number of screws, extruders can be classified as single-screw extruders and twin-screw extruders; based on the type of mold, extruders can be classified as pipe extruders and profile extruders.
[0003] According to the authorized patent "CN217514508U", a PE pipe extruder is provided, including an extruder and a heating component. The heating component includes an installation sleeve, which is fitted onto the side wall of the extruder barrel. Connecting boss A and connecting boss B are respectively provided at both ends of the installation sleeve. A limiting boss A is provided on the outer wall of the barrel corresponding to connecting boss A, and a limiting boss B is provided on the outer wall of the barrel corresponding to connecting boss B. Connecting boss A and limiting boss A are connected by a connecting flange A, and connecting boss B and limiting boss B are connected by a connecting flange B. The installation sleeve, connecting boss A, connecting boss B, limiting boss A, limiting boss B, the outer wall of the barrel, and connecting flanges A and B form a closed cavity for holding heat transfer oil. A plurality of electric heating tubes are provided inside the cavity for heating the heat transfer oil in the cavity.
[0004] The aforementioned technical solutions, when used in practice, have certain limitations in the material handling stage of traditional PE pipe extruders. Most extruders' feed hoppers only serve as channels for raw material storage and transportation, lacking effective mixing devices. This results in the PE raw materials not being fully and evenly mixed before entering the extrusion system. When the raw materials have problems such as uneven particle size or insufficient additive dispersion, the extruded PE pipes are prone to quality defects such as uneven wall thickness and unstable mechanical properties, seriously affecting the product's performance and safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4A PE pipe extruder includes a main body 1, a controller 2 is provided on the outside of the main body 1, a feed hopper 3 is fixedly connected to the top of the main body 1, a discharge pipe 6 is fixedly connected to the outside of the main body 1, and a stirring mechanism 4 is provided on the top of the feed hopper 3.
[0027] The stirring mechanism 4 includes a cover plate 41, a motor 42 fixedly connected to the top of the cover plate 41, a rotating rod 43 fixedly connected to the output end of the motor 42, an electric telescopic rod 44 fixedly connected to the bottom of the rotating rod 43, a transmission rod 45 fixedly connected to the bottom of the electric telescopic rod 44, a rotating groove 46 is provided in the inner wall of the feed hopper 3, a limiting rod 47 is rotatably connected inside the rotating groove 46, a rotating shaft 48 is fixedly connected between the limiting rods 47, a stirring blade 49 is fixedly connected to the outside of the rotating shaft 48, and a rubber ring 410 is fixedly connected to the top of the rotating shaft 48.
[0028] Furthermore: the cover plate 41 is located above the feed hopper 3 and is movably connected to the top of the feed hopper 3. The rotating rod 43 passes through the inside of the cover plate 41. The electric telescopic rod 44 and the transmission rod 45 are movably connected inside the feed hopper 3. The rotating shaft 48 is movably connected inside the feed hopper 3 through the limiting rod 47. The stirring blades 49 are symmetrically distributed on the outside of the rotating shaft 48. There is a gap between the stirring blades 49 and the inner wall of the feed hopper 3. The transmission rod 45 is located directly above the rubber ring 410 and the two are compatible.
[0029] It should be noted that the operator sets operating parameters such as temperature, rotation speed, and extrusion speed through the controller 2 on the outside of the main body 1. PE raw material is poured into the feed hopper 3 at the top of the main body 1. The main body 1 is started, and its internal extrusion system operates, heating, melting, and extruding the raw material, which is finally extruded into a PE pipe through the discharge pipe 6 on the outside of the main body 1.
[0030] Specifically: Controller 2 typically employs an intelligent control system, integrating multiple monitoring components such as temperature and pressure sensors, enabling real-time acquisition of key data during equipment operation. Operators can not only set initial parameters but also dynamically adjust them based on actual conditions during extrusion, such as changes in raw material characteristics and fluctuations in ambient temperature, achieving precise control and ensuring the stability of PE pipe extrusion and the consistency of product quality. The extrusion system inside the main body 1 includes a heating device and a screw drive mechanism. The heating device generally uses segmented heating, with different temperatures set for different sections to meet the melting requirements of the raw material at different stages. The screw, through the thrust generated by its rotation, pushes the molten raw material towards the discharge pipe 6. The screw's rotational speed and pitch design directly affect the conveying efficiency and mixing uniformity of the raw material.
[0031] As a further improvement of this utility model, a sealing mechanism 5 is provided between the cover plate 41 and the feed hopper 3. The sealing mechanism 5 includes a connecting plate 51, a rotating part 52 is provided between the connecting plates 51, an extension rod 53 is fixedly connected to the outer side of the cover plate 41, a fixing block 54 is fixedly connected to the bottom of the extension rod 53, a positioning hole 55 is provided in the side wall of the fixing block 54, a snap-fit groove 56 is fixedly connected to the outer side of the feed hopper 3, a movable tube 57 is fixedly connected to the outer side of the snap-fit groove 56, a snap-fit rod 58 is movably connected inside the movable tube 57, and a compression spring 59 is fixedly connected to the snap-fit rod 58.
[0032] Furthermore: the connecting plates 51 are symmetrically distributed on the outside of the feed hopper 3, the end of the rotating part 52 away from the connecting plates 51 is fixedly connected to the outside of the cover plate 41, the fixing block 54 is adapted to the snap-fit groove 56, and one end of the snap-fit rod 58 is movably connected to the inside of the positioning hole 55.
[0033] It should be noted that the rotating component 52 generally adopts a hinge or bearing structure, and is precision machined and surface treated to have high rotation accuracy and wear resistance, which can ensure that the cover plate 41 rotates smoothly during frequent opening and closing, and has a long service life.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] Working principle: After the raw materials are poured in, the stirring mechanism 4 is started. The motor 42 at the top of the cover plate 41 works, and its output end drives the rotating rod 43 to rotate. The rotating rod 43 passes through the cover plate 41 and transmits power to the feed hopper 3. The electric telescopic rod 44 at the bottom of the rotating rod 43 can be adjusted in length as needed, which drives the transmission rod 45 to move up and down in the feed hopper 3. When the transmission rod 45 moves down, it contacts and presses down the rubber ring 410 at the top of the rotating shaft 48, so that the rotating shaft 48 rotates along the rotating groove 46 on the inner wall of the feed hopper 3 under the action of the limiting rod 47. The symmetrical stirring blades 49 fixed on the outside of the rotating shaft 48 rotate accordingly to stir the raw materials. When stirring or cleaning is not required, the electric telescopic rod 44 drives the transmission rod 45 to move up and separate from the rubber ring 410. The rotating shaft 48 and the stirring blades 49 stop working.
[0036] When adding raw materials or repairing the stirring mechanism 4, the cover plate 41 needs to be operated. The sealing mechanism 5 ensures that the cover plate 41 is sealed with the feed hopper 3. When closing the cover plate 41, the cover plate 41 is rotated to the top of the feed hopper 3 with the rotating part 52 between the connecting plates 51 as the axis. The outer extension rod 53 of the cover plate 41 drives the fixing block 54 to move down and align with the outer snap-fit groove 56 of the feed hopper 3. In the movable tube 57 outside the snap-fit groove 56, under the action of the compression spring 59, the snap-fit rod 58 pops out and inserts into the positioning hole 55 on the side wall of the fixing block 54 to achieve sealing and fixing. When opening the cover plate 41, the snap-fit rod 58 is manually pressed to overcome the spring force and withdraw from the positioning hole 55, and then the cover plate 41 can be rotated to open.
