[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0025] Figure 1 , Figure 2 and Figure 3The PVC production transverse material guiding mixing extrusion molding mechanism shown includes a horizontal reaction tank 1, an external electrically controlled push rod 2, a drive motor 3, and an internal electrically controlled push rod 4. The horizontal reaction tank 1 has a transverse reaction chamber 5 inside. A transverse translation seat 6 controlled by the external electrically controlled push rod 2 is slidably connected inside the transverse reaction chamber 5. A top reaction groove 7 is opened on the upper surface of the transverse translation seat 6. A spiral material guiding mechanism controlled by the drive motor 3 is movably assembled inside the top reaction groove 7. A front extrusion groove 8 is opened at the top of the inner side of the transverse translation seat 6 below the top reaction groove 7. An extrusion linkage block 9 controlled by the internal electrically controlled push rod 4 is slidably assembled inside the front extrusion groove 8.
[0026] Working principle: The external electric push rod 2 drives the horizontal translation seat 6 to move left and right, the drive motor 3 drives the spiral guide mechanism to rotate, and the internal electric push rod 4 drives the extrusion linkage block 9 to move inside the front extrusion groove 8. The extrusion linkage block 9 moves to the left opening position of the front extrusion groove 8 on the left side. At this time, the left plane of the extrusion linkage block 9 and the left plane of the horizontal translation seat 6 are on the same plane, which facilitates extrusion.

[0030] People introduce materials into the top connecting pipe 14 through different external conveying pipes 13, and then flow into the top reaction tank 7 through the internal guide hole 15. The material is guided at the same time as the horizontal translation seat 6 is translating, which can improve the uniformity of input. Then, while conveying the material, the spiral guide mechanism is controlled to rotate to drive the mixing and convey the mixing from right to left, so as to facilitate the squeezing of the mixing inside the top reaction tank 7 into the front extrusion tank 8. Then, a top guide cover is set on the left side of the upper opening of the top reaction tank 7 to facilitate the introduction of the mixing into the front extrusion tank 8.
[0031] Furthermore, in order to facilitate the assembly, a circular assembly blind hole is provided at the center of the left inner wall of the top reaction tank 7, and a circular assembly through hole is provided at the center of the right inner wall of the top reaction tank 7. The spiral guide mechanism includes a transverse drive shaft 16 with its two ends inserted into the circular assembly blind hole and the circular assembly through hole respectively, and a spiral structure guide blade 17 axially fixed to the outside of the transverse drive shaft 16.
[0032] The drive motor 3 drives the transverse transmission shaft 16 to rotate, thereby controlling the spiral structure guide blades 17, which in turn controls the material in the top reaction tank 7 to move from right to left.
[0033] Furthermore, in order to facilitate material feeding, an internal linkage port 18 is provided on the upper end of the inner top surface of the front extrusion tank 8, which is connected to the bottom of the top reaction tank 7.
[0034] Furthermore, in order to coordinate with the rotation adjustment translation, the interior of the horizontal translation seat 6 is provided with an internal thread adjustment blind hole 19 with an opening on the right side below the top reaction tank 7. The left thread adjustment rod of the external electric control push rod 2 is threadedly connected to the horizontal translation seat 6 by inserting into the internal thread adjustment blind hole 19.
[0035] Furthermore, in order to facilitate bottom discharge, a bottom discharge port 20 is provided on the left side of the lower surface of the horizontal reaction tank 1, which is connected to the interior of the horizontally placed reaction chamber 5. A flip-type bottom discharge plate 21 is movably installed inside the bottom discharge port 20.
[0036] Furthermore, in order to facilitate the closing and locking, a lateral tilting groove 23 with a built-in lateral assembly shaft 22 is provided on the lower surface of the horizontal reaction vessel 1 on the right side of the bottom discharge port 20. The tilting bottom discharge plate 21 is movably connected to the bottom discharge port 20 by the right-side integrated assembly shaft tube 24 sleeved on the outside of the lateral assembly shaft 22. A T-shaped telescopic adjustment groove 26 with a built-in elastic locking block 25 is provided on the left side of the tilting bottom discharge plate 21. A lateral locking groove 27 that cooperates with the elastic locking block 25 is provided on the left inner wall of the bottom discharge port 20.
[0037] Then control the separation flip and active assembly.
[0038] Furthermore, in order to regulate the internal temperature, a serpentine internal temperature regulating channel 28 is provided inside the horizontal reaction tank 1 around the horizontally placed reaction chamber 5. External temperature regulating connecting pipes 29, which are connected to the inlet and outlet of the internal temperature regulating channel 28, are fixedly connected to both sides of the bottom discharge port 20 on the outer side of the horizontal reaction tank 1.
[0039] Cooling water is introduced into the internal temperature-controlled flow channel 28 from the external temperature-controlled connecting pipe 29 to form circulating cooling water, which will accelerate the curing and separation efficiency from the inner wall of the horizontal reaction chamber 5.
[0040] This invention discloses a horizontally guided mixing and extrusion molding mechanism for PVC production, which adopts a horizontal layout. By controlling the translation of the horizontally positioned translational seat 6 inside the horizontal reaction chamber 5, materials at different positions are guided and conveyed, and the mixture is horizontally extruded and molded, thereby achieving rapid mixing, conveying, and curing, significantly improving production efficiency. Multiple external conveying pipes 13 are fixed to the top connecting pipes 14 on the upper surface of the horizontal reaction tank 1. Materials are introduced into the top reaction tank 7 according to the reaction sequence through internal guide holes 15. The reaction and mixing time can be controlled by the translation speed of the horizontally positioned translational seat 6, making reaction and mixing control more convenient. The translational conveying also ensures more uniform mixing. A spiral guiding mechanism inside the top reaction tank 7 further facilitates the process. The mixture is moved into the pre-extrusion tank 8, and then the extrusion linkage block 9 inside the pre-extrusion tank 8 discharges the material into the horizontal reaction chamber 5, thereby closing the left opening of the horizontal translation seat 6. After the mixing is completed, the material is transferred and extruded, and the extrusion molding and curing are completed on the far left of the horizontal reaction chamber 5. It can be quickly cured into a specified state as needed, which greatly improves the material conveying and production efficiency. A bottom discharge port 20 with a built-in flip-type bottom discharge plate 21 is opened on the lower surface of the horizontal reaction tank 1, which can quickly flip and discharge the material after production, greatly improving the discharge efficiency. Inside the horizontal reaction tank 1, a serpentine internal temperature-regulating flow channel 28 is opened around the horizontal reaction chamber 5, which can regulate the internal temperature and accelerate the reaction efficiency of PVC raw materials.
