[0002] The foam board is also known as polystyrene foam board. The EPS board is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agents in a mold after pre-expansion by heating. It has the structural characteristics of fine closed pores and is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ship insulation, floor heating, decoration carving, etc., with very wide applications.

[0003] When producing the foam board, it needs to be made by expanding and foaming polystyrene particles, that is, expandable polystyrene resin beads, as the basic raw material. When the polystyrene particles are in the mixing and expanding and foaming processes, due to the small mass and light volume of the foamed particles after expansion and foaming, static electricity is easily generated due to friction between the foam particles during mixing, resulting in some particles adhering to the inner wall of the mixing barrel during discharging, reducing the output rate of the device. Summary of the Utility Model

[0008] As an improvement, the self-rotating mixing component includes a self-rotating mixing motor, a driving wheel, a mixing driven wheel, an adjusting chute, a mixing shaft, and mixing members. The self-rotating mixing motor is arranged on the support plate, and the output shaft of the self-rotating mixing motor penetrates through the support plate.

The adjusting chute penetrates through the mixing driven wheel. The mixing shaft extends parallel to the same side as the foam adsorption scraping rod from the adjusting chute. The mixing members are arranged in an array on the mixing shaft.

[0009] As an improvement, a connecting shaft is connected between the scraping adjusting bracket and the adjusting chute. The connecting shaft is slidably connected to the adjusting chute.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-6 shown, a mixing device for foam board production proposed by the present invention includes a foam mixing bucket 1. A discharge valve 2 is provided through the lower part of the side wall of the foam mixing bucket 1. A bracket 3 extends upward from the foam mixing bucket 1. A mixing scraping assembly 4 is supported on the bracket 3, and a self-rotating mixing assembly 5 is provided at one end of the mixing scraping assembly 4.

[0024] As Figure 2 、 3 shown, the mixing scraping assembly 4 includes a mixing scraping motor 6, a rotating shaft 7, a scraping adjustment bracket 8, a scraping sliding frame 9 and a foam adsorption scraping rod 10. The mixing scraping motor 6 is supported by the bracket 3. The rotating shaft 7 is arranged on the output shaft of the mixing scraping motor 6 and rotates on the inner bottom wall of the foam mixing bucket 1. The scraping adjustment bracket 8 is fixed on the circumferential surface of the rotating shaft 7. The scraping adjustment bracket 8 is star-shaped and has five sides. A support plate 11 extends from a group of scraping adjustment brackets 8. The self-rotating mixing assembly 5 is arranged on the support plate 11. The scraping sliding frame 9 is slidably connected to the scraping adjustment bracket 8. The foam adsorption scraping rod 10 vertically extends into the foam mixing bucket 1 from the end of the scraping sliding frame 9. The cross-section of the foam adsorption scraping rod 10 is comma-shaped.

[0025] As Figure 4 、 56, the self-rotating mixing assembly 5 includes a self-rotating mixing motor 12, a driving wheel 13, a mixing driven wheel 14, an adjusting chute 15, a mixing shaft 16 and a mixing piece 17. The self-rotating mixing motor 12 is arranged on the support plate 11 and the output shaft of the self-rotating mixing motor 12 passes through the support plate 11. The driving wheel 13 is arranged on the output shaft of the self-rotating mixing motor 12. The mixing driven wheel 14 is connected and sleeved on the outer side of the rotating shaft 7 and meshes with the driving wheel 13. The rotating shaft 7 and The mixing driven wheel 14 is connected through an anti-interference bearing 19, and an adjusting groove 15 is set through the mixing driven wheel 14. A connecting shaft 18 is connected between the scraping adjustment bracket 8 and the adjusting groove 15. The connecting shaft 18 and the adjusting groove 15 are slidably connected. The adjusting groove 15 is set in an arc groove and there are five groups of them in a regular circular array. The mixing shaft 16 extends from the adjusting groove 15 to the same side parallel to the foam adsorption scraping rod 10, and the mixing pieces 17 are arranged in an array on the mixing shaft 16.

[0026] When in use, polystyrene particles are added into the foam mixing barrel 1 when producing the foam board, and the mixing scraping motor 6 is started to drive the rotating shaft 7 to rotate in the foam mixing barrel 1. At this time, the rotating shaft 7 will be linked with the scraping adjustment bracket 8 to rotate with the scraping sliding frame 9 and the foam adsorption scraping rod 10 in the foam mixing barrel 1. With the rotation of the scraping adjustment bracket 8, the entire self-rotating mixing component 5 rotates in a circle with the rotating shaft 7 as the center.

[0027] When the polystyrene particles are electrostatically adsorbed on the inner wall of the foam mixing barrel 1 too much during the production process, the user starts the self-rotating mixing motor 12. At this time, the self-rotating mixing motor 12 drives the driving wheel 13 to rotate, and rotates separately with the mixing driven wheel 14. Under the setting of the anti-interference bearing 19, the rotation of the mixing driven wheel 14 will not interfere with the rotation of the rotating shaft 7. Then the rotation of the mixing driven wheel 14 drives the adjusting chute 15 to rotate in a circle, thereby pushing the mixing shaft 16 to slide in the adjusting chute 15, and changing the scraping sliding frame in a linkage manner. 9 is in the position on the scraping adjustment bracket 8, realizing the effect of the scraping sliding frame 9 sliding on the scraping adjustment bracket 8, and finally driving the foam adsorption scraping rod 10 towards the direction close to the inner wall of the foam mixing barrel 1, and when the end of the foam adsorption scraping rod 10 is released from the inner wall of the foam mixing barrel 1, the self-rotating mixing motor 12 is turned off. At this time, the foam adsorption scraping rod 10 moves together with the scraping adjustment bracket 8 rotating around the rotating shaft 7, and the polystyrene particles electrostatically adsorbed on the foam mixing barrel 1 are scraped off.
