DETAILED DESCRIPTION

[0026] Embodiment 1

[0027] like Figure 1-Figure 4 As shown, a plastic building board extrusion molding device proposed by the utility model includes an extruder 2, a storage barrel 7, a rotating shaft 10, a driving assembly 12, a stirring shaft 13 and a cylindrical tube 17. The bottom of the extruder 2 is connected to the base 1, and the extruder 2 is connected to the input end of the mold 4. The extruder 2 is provided with a heating assembly 3 for heating the raw materials inside thereof, and the heating assembly 3 includes but is not limited to an electric heating coil surrounding the outside of the extruder 2. The output end of the storage barrel 7 is connected to the input end of the extruder, and the storage barrel 7 is connected to the fixed plate 8. The fixed plate 8 is rotatably connected to the flip cover 9, and the flip cover 9 is sealed with the storage barrel 7 to prevent dust from entering the storage barrel 7. The rotating shaft 10 is located in the storage barrel 7 and is rotatably connected to the fixed plate 8. The rotating shaft 10 is connected to the spiral plate 11, and the spiral plate 11 is inserted into the output pipe of the storage barrel 7 and slides with its inner wall. A cylindrical hole is set in the rotating shaft 10. The driving assembly 12 is connected to the fixed plate 8 and drives the rotating shaft 10 to rotate. The driving assembly 12 includes a motor. A bracket is arranged on the fixed plate 8, the motor is rotatably connected to the bracket, the rotating shaft 10 is rotatably connected to the bracket, a first gear is arranged on the rotating shaft 10 between the fixed plate 8 and the horizontal plate of the bracket, the output end of the motor is connected to the second gear, and the first gear is meshed with the second gear. The stirring shaft 13 is inserted into the rotating shaft 10 and slidably connected thereto, the stirring shaft 13 is connected to a plurality of stirring paddles 14, the stirring paddles 14 penetrate the rotating shaft 10 and are slidably connected thereto, and a slider 15 is connected to the top of the stirring shaft 13. The stirring shaft 13 is inserted into the cylindrical hole and slidably connected thereto, and a chute communicating with the cylindrical hole is arranged on the rotating shaft 10, and each stirring paddle 14 is respectively located in the corresponding side chute and slidably connected thereto. The cylindrical tube 17 is connected to the fixed plate 8, and a guide groove 171 with ups and downs is arranged in the cylindrical tube 17, and the slider 15 is located in the guide groove 171 and is slidably connected to its inner wall.

[0028] In this embodiment, the raw materials are put into the storage barrel 7, and then the motor is started. The motor drives the second gear and the rotating shaft 10 to rotate by driving the first gear. In the initial working state, the spiral plate 11 rotates upward during the rotation of the rotating shaft 10. The rotation of the rotating shaft 10 drives the spiral plate 11 to rotate, and since the rotating shaft 10 and the stirring shaft 13 are limited by the stirring paddle 14, the stirring paddle 14 and the stirring shaft 13 rotate synchronously at this time. When the stirring shaft 13 is in a rotating state, the slider 15 at the top thereof slides in the guide groove 171. Since one end of the guide groove 15 is higher than the other end, the slider 15 drives the stirring shaft 13 to reciprocate up and down. At this time, the working state of the stirring paddle 14 is to rise and fall while rotating. Through this structure, the working space of the stirring paddle 14 can be expanded, and the efficiency of mixing the materials in the storage barrel 7 can be improved. After the materials are mixed, the motor drives the rotating shaft 10 to rotate in the opposite direction, and the spiral plate 11 rotates downward, and the extruder 2 is started at the same time. The spiral plate 11 sends the mixed material into the extruder and then is pushed by the auger in the extruder. The material is heated by the heating component 3 to a molten state during the pushing process, and then the molten raw material enters the mold 4, is formed by the mold 4, and is gradually cooled and shaped and output.

[0029] Embodiment 2

[0030] like Figure 1 and Figure 5 As shown, the plastic building board extrusion molding device proposed by the utility model, compared with the first embodiment, the die 4 is provided with an annular groove 401 near its outlet, and the annular groove 401 includes multiple groups, and adjacent annular grooves 401 are distributed at equal intervals. An annular cover 5 for closing the annular groove 401 is provided on the die 4 to form an annular channel between the annular cover 5 and the inner wall of the annular groove 401, and a water outlet 501 for drainage is provided at the bottom of the annular cover 5, and a water inlet pipe 6 for injecting water into the annular channel is provided on the annular cover 5, and the water inlet pipe 6 is externally connected to a water supply mechanism.

[0031] In this embodiment, the raw material is extruded by the extruder 2 and then formed in the mold 4. After forming, it continues to be transported along the inner cavity of the mold 4 and output along the outlet of the mold 4. During the output process, the water supply mechanism injects water into the annular channel along the water inlet pipe 6. The water flows in the annular channel and is finally discharged from the water outlet 501. This structure limits the flow path of the water, improves the heat exchange efficiency between the water and the outlet side of the mold, accelerates the cooling of the plate, and makes the cooling more uniform, thereby achieving the purpose of improving production efficiency.

[0032] Embodiment 3

[0034] In this embodiment, the impeller 16 rotates along with the stirring shaft 13. The impeller 16 drives the air to flow during the rotation. The outside air enters the cylindrical tube 17 along the air inlet 172 and is discharged along the upper end opening of the cylindrical tube 17. By driving the air flow, the heat generated during the sliding of the slider 15 and the guide groove 171 is dissipated, thereby achieving cooling and heat dissipation of the slider 15 and the cylindrical tube 17.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
