Problems solved by technology

[0003] In summary, the present inventors found that the existing extruder mainly has the following defects: since polypropylene needs to continuously add raw materials while extruding the extruder, the product can be continuously formed and extruded, and the product is At the same time of processing, due to the heating and forming of the equipment, a viscous material will be formed, so that a small amount of material will stick to the extrusion pipe during extrusion, and then after the extruder stops working, it will form due to the cessation of heating. The material is naturally cooled, so it will be fixed in it after cooling, and it is not easy to clean due to the structure of the pipeline, so that after the material is cooled and fixed in the extrusion pipeline, it will form a subsequent processing material and cause the surface of the material to be residual. destroyed by

Embodiment 1

[0028] Figure 1 to Figure 6 Shown:

[0029] The invention provides a twin-screw extruder for processing glass fiber reinforced polypropylene,

[0030] Its structure includes a power distribution base 1, a control box 2, a limit block 3, a feed end 4, a bracket 5, and an extrusion pipeline 6. The upper end of the power distribution base 1 is attached to the lower end of the control box 2 and energized connected, the limit block 3 is installed on the upper end of the control box 2, the side of the feed end 4 is attached to the side of the limit block 3, the extrusion pipe 6 is installed on the lower end of the feed end 4 and In communication, the bracket 5 is installed on the lower end of the extrusion pipe 6 and fixedly connected.

[0031] The extrusion pipeline 6 is provided with a connection frame 61, a solid layer 62, a model body 63, a balance frame 64, and a scraping device 65. The connection frame 61 is embedded with a solid layer 62 and is fixedly connected. The model...

[0039] Figure 7 to Figure 9 Shown:

[0040] The invention provides a twin-screw extruder for processing glass fiber reinforced polypropylene,

[0041] Its structure includes that the slide rail 651 is provided with a limit layer b1, a guide port b2, a channel b3, and an actuator b4, the upper end of the limit layer b1 is equipped with a guide port b2 and integrated, and the channel b3 is installed on the guide port b2 The activator b4 is embedded in the lower end of the channel b3 and communicates with each other. The guide port b2 is consistent with the diameter of each component, and the channel b3 below it is in a slope state. The guide port b2 passes through its own The size of the diameter can effectively collect the residual material, and can prevent the material from falling on the periphery of the guide port b2 during the scraping process.

[0042] Wherein, the activator b4 is provided with a fixed ring b41, a power wheel b42, a movable rod b43, and a bonding layer ...

Abstract

The invention provides a twin-screw extruder for processing glass fiber reinforced polypropylene. The lower end of the box is attached and electrically connected, the limit block is installed on the upper end of the control box, and the side of the feed end is attached to the side of the limit block. The invention can push the product while extruding the product by the extruder The scraping and scraping device can quickly return to the position in the gap added by the raw material, so that it can scrape off the sticky product residue in the extrusion pipeline while returning to the position, so that it can be returned by the spring While scraping off, the scraping shaft in the scraping device can further scrape off the residue on itself during the scraping process, so as to prevent the residue from adhering to the product due to the heating of the product after extrusion. Extruded into the pipeline, while the subsequent product is affected by the residue when it is extruded.

Description

technical field [0001] The invention relates to the field of polypropylene, in particular to a twin-screw extruder for processing glass fiber reinforced polypropylene. Background technique [0002] The twin-screw extruder can fully plasticize and evenly mix the materials through its own double-screw rods, and can effectively extrude the materials according to the shape of the die outlet through the shape of the exit die, so that the extrusion The machine can effectively mix the materials and continuously extrude them, so that it can effectively guarantee the product quality; [0003] In summary, the present inventors found that the existing extruder mainly has the following defects: since polypropylene needs to continuously add raw materials while extruding the extruder, the product can be continuously formed and extruded, and the product is At the same time of processing, due to the heating and forming of the equipment, a viscous material will be formed, so that a small am...
