Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber light tube production, in particular to a smooth tube production extrusion device. Background Art
[0002] The smooth tube production extrusion device is a device specially used to produce plastic tubes. The core part of the device is the extruder, which is responsible for heating the plastic raw materials and extruding them into tubes.
[0003] The screw inside the extrusion system rotates in the extrusion barrel, pushing the molten plastic forward and extruding it into a tube through the die mouth.
[0004] In this process, when producing smooth tubes, the plastic material needs to be mixed with pigments to color the tubes, and the final extrusion of the smooth tubes will cause some defects on the surface of the extruded smooth tubes. When smooth tubes need to be produced, the quality of the smooth tubes can be judged directly by observing the color of the surface of the tubes after production. This requires that the molten plastic material can be evenly mixed with other raw materials before output in the early stage of production. If the raw materials are melted and mixed before subsequent output, it will lead to excessive energy consumption and prolonged process time. Utility Model Content

DETAILED DESCRIPTION
[0025] The utility model embodiment provides a smooth tube production extrusion device, such as Figure 1-4 As shown, it includes a plurality of hybrid shaping plates 101, and the plurality of hybrid shaping plates 101 are combined and connected. The outer shell of the hybrid shaping plate 101 is two semicircular profiles. The end faces of both sides of the hybrid shaping plate 101 are respectively provided with connecting mounting rods 103. The connecting mounting rods 103 on both sides are fixedly connected and combined by locking clamps 104. The hybrid shaping plate 101 at the tail end is connected with a plastic guide tube 105. The plastic guide tube 105 is provided with an injection molding cavity 111 which is connected with the extruded plastic pipeline. The hybrid shaping plate 101 at the head end is connected with an extrusion guide plate 102.
[0026] Furthermore, a mounting connector 106 is fixedly provided on one end surface of the hybrid shaping plate 101 , and the hybrid shaping plates 101 on both sides are mounted and fixedly connected via the mounting connector 106 .
[0027] Furthermore, two mixing chambers 110 are provided in the mixing shaping plate 101, and the mixing chambers 110 on both sides are symmetrically positioned.
[0028] Furthermore, two guide holes 109 are provided between the mixing chambers 110 on both sides of the mixing shaping plate 101, and the guide holes 109 on both sides are symmetrically positioned.
[0029] Furthermore, arc-shaped guide grooves 107 are provided on both side end surfaces of the mixing chamber 110 to play a guiding role.
[0030] Furthermore, the mixing chamber 110 at the rear end is connected to the injection chamber 111 .
[0031] Furthermore, a connecting hole 108 is provided at the center position between the mixing chambers 110 in the mixing shaping plates 101 on both sides close to each other.
[0032] Furthermore, an extrusion cavity 112 is provided in the extrusion guide plate 102 , and the extrusion cavity 112 is communicated with one end of the plastic shaping mold.
[0033] When using this solution, first the combined hybrid shaping plates 101 are formed into a combined device, and then the plastic guide tube 105 is connected to the hybrid shaping plate 101 at the rear end, and the extrusion guide plate 102 is connected to the hybrid shaping plate 101 at the top end.
[0034] When it is necessary to produce and output smooth tubes, the raw material device will input the molten plastic raw material and the processed raw material mixed into the mixing chamber 110 at the tail end through the injection chamber 111. At this time, the production raw materials will diffuse under the guidance of the mixing chamber 110, and will be guided in an arc shape by the arc guide grooves 107 at both ends, so that the production raw materials will be input into the mixing chamber 110 on the other side through the guide hole 109, and will be concentrated and mixed through the connecting hole 108 and output backward to the subsequent mixing and shaping plate 101. After the production raw materials are broken up and mixed through the multi-layer mixing chamber 110, they will be mixed multiple times to achieve a more uniform mixing effect.

At this time, the surface of the smooth tube produced can be smooth and the color is brighter, which can further improve the production efficiency of the smooth tube.
