Embodiment 1

[0031] refer to Figure 1-2 and Figure 5-6, a high-temperature extrusion molding machine, including an extrusion box 1, a power box 2 arranged on one side of the extrusion box 1, a feed box 4 at the top of the extrusion box 1 and a base 3 at the bottom of the extrusion box 1, the said The top of the feeding box 4 is provided with a stirring motor 16, the interior of the feeding box 4 is provided with a stirring shaft 14, the stirring shaft 14 is connected with the output shaft of the stirring motor 16, and stirring blades 15 are arranged on both sides of the stirring shaft 14 alternately, The upper end of one side of the feeding box 4 is provided with a feeding port 7, a layer of electric heating layer 17 is arranged on the inner side wall of the feeding box 4, and a feeding port 19 is provided on one side of the bottom of the feeding box 4. The extrusion box 1 is connected, and a support plate 21 is provided on the other side of the bottom of the feeding box 4. The support ...

Embodiment 2

[0038] like image 3 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the number of helical blades of the first helical blade 28 is half of that of the second helical blade 29, and the first helical blade 28 and the second helical blade 29 are arranged alternately. . It can effectively make the master batch fall into the lower second helical blade 29 and the third helical blade 30 as soon as possible, speed up the extrusion efficiency, reduce the use of electric heating wire, and save energy.

Embodiment 3

[0040] like Figure 4 As shown, this embodiment is basically the same as Embodiment 1. Preferably, a No. 1 motor 33 is provided at the bottom end of the power box 2, and the third rotating shaft 31 and the first rotating shaft 40 extend through the extrusion plastic box 1 into the power box 2 , is rotatably connected with the side wall of the power box 2, the output shaft of the No. 1 motor 33 is rotatably connected with the third shaft 31 and the first shaft 40 through the rotating belt 34, and the second shaft 39 is connected with the No. 2 motor 32 in the power box 2. The output shaft is fixedly connected, and the No. 2 motor 32 and No. 1 motor 33 are electrically connected to the control button 10 . The third rotating shaft 31 and the first rotating shaft 40 can be rotated synchronously, and the rotational speed of the second rotating shaft 39, the third rotating shaft 31 and the first rotating shaft 40 can be easily adjusted, improving the shearing efficiency and saving p...

Abstract

The invention discloses a high-temperature extrusion molding machine, which relates to the technical field of plastic processing. It includes an extruding box, a power box, a feeding box and a base, and a stirring shaft is arranged inside the feeding box, a layer of electric heating layer is arranged on the inner side wall of the feeding box, and an extrusion mechanism, the extrusion mechanism includes the first screw blade, the second screw blade and the third screw blade and are interlaced with each other. One end of the first rotating shaft, the second rotating shaft and the third rotating shaft passes through the side wall of the extrusion box, and the rotation in the power box The output shafts of the motors are connected, and electric heating wires are arranged on the first spiral blade and the second spiral blade. The invention overcomes the deficiencies of the prior art, is reasonable in design, and is easy to use. After preliminary premixing of the masterbatch, the spiral extrusion is carried out, and at the same time, the spiral blade heating method is used to effectively improve the extrusion efficiency, prevent heat waste, and reduce manpower. loss.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-temperature extrusion molding machine. Background technique [0002] The extruder is an important plastic machine. The production and manufacture of most plastic products can be realized by extrusion molding. Generally, the extruder uses a screw with a specific shape to rotate in a heated barrel to extrude plastic. forming. [0003] When the extruder is in use, most of the plastic masterbatch is directly added to the barrel, heated by the heating element inside the barrel, and then extruded through the spiral blade on the screw extrusion rod. In the process of stirring, in order to make the masterbatch mix More uniform, twin-screw or three-screw extruder is often used for extrusion. Among them, the three-screw extruder has the advantages of strong plasticizing ability, good mixing effect, and better self-cleaning performance of the twin-screw plastic extruder. ...
