Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a feeding device for EPS foam production, including a feeding box 1. Multiple support columns 2 are fixedly connected in a circular array to the bottom of the feeding box 1. A feeding pipe 3 is fixedly connected to the upper ends of the multiple support columns 2. A directional pipe 4 is rotatably connected to the upper end of the feeding pipe 3. A spiral auger 5 is rotatably connected to the inner sides of the feeding pipe 3 and the directional pipe 4. A first discharge hole 6 is opened on the surface of the directional pipe 4. A sealing plate 7 is slidably connected to the outer surface of the directional pipe 4. A second discharge hole 8 corresponding to the first discharge hole 6 is opened on the surface of the sealing plate 7. A discharge pipe assembly 9, fixedly connected to the sealing plate 7, is provided on the outer side of the second discharge hole 8. A fixed-point discharge pipe assembly 9 is fixedly connected to the outer surface of the directional pipe 4. Positioning ring 10 has a first threaded hole 11 on its surface, and a locking bolt 12 is internally threaded into the first threaded hole 11. The outer surface of the feeding pipe 3 has multiple positioning holes 13 in a ring array corresponding to the locking bolt 12. By setting up the feeding pipe 3, adjusting pipe 4, spiral auger 5, positioning ring 10 and locking bolt 12, after loosening the locking bolt 12, the position of the discharge pipe assembly 9 can be adjusted by rotating the adjusting pipe 4. By tightening the locking bolt 12, the locking bolt 12 is inserted into the positioning hole 13, which can fix the adjusting pipe 4 and the discharge pipe assembly 9. This allows the staff to adjust the orientation of the discharge port of the discharge pipe assembly 9 according to their needs, providing convenience for the staff.

[0025] There are multiple first discharge holes 6, second discharge holes 8, and discharge pipe assemblies 9. By setting multiple first discharge holes 6, second discharge holes 8, and discharge pipe assemblies 9, materials can be fed to multiple directions simultaneously, thus meeting the needs of multiple production lines.

[0026] A telescopic push rod 14 is fixedly connected to the upper surface of the directional pipe 4. An end plate 15 is fixedly connected to the upper end of the telescopic push rod 14. A push-pull rod 16 is fixedly connected to the lower surface of the end plate 15. The lower end of the push-pull rod 16 is fixedly connected to the upper end of the sealing plate 7. The telescopic push rod 14 can be extended or retracted to drive the end plate and the push-pull rod 16 to rise or fall, thereby driving the sealing plate 7 to rise or fall. By raising or lowering the sealing plate 7, the first discharge hole 6 and the second discharge hole 8 can be connected or disconnected, thereby enabling individual control of the discharge of each discharge pipe assembly 9. Compared with the prior art, this utility model can control one or more discharge pipe assemblies 9 to discharge according to needs, thereby improving practicality and ease of operation.

[0027] A limiting frame 17 is fixedly connected to the outer surface of the directional tube 4. A limiting groove 18 is opened on the inner wall of the limiting frame 17. The two sides of the sealing plate 7 are slidably connected to the limiting groove 18. By setting the limiting frame 17 and the limiting groove 18, the sealing plate 7 can be limited by the limiting frame 17, which can make the up and down movement of the sealing plate 7 more stable.

[0028] A power motor 19 is fixedly connected to the lower surface of the loading box 1. The output end of the power motor 19 is connected to the spiral auger 5. The operation of the power motor 19 can drive the spiral auger 5 to rotate, thereby conveying the material at the bottom of the loading box 1 to the top of the directional pipe 4.

[0029] The discharge pipe assembly 9 includes a first discharge pipe 20 and a second discharge pipe 21. The first discharge pipe 20 is fixedly connected to the surface of the sealing plate 7, and the second discharge pipe 21 is slidably connected to the outside of the first discharge pipe 20. A limiting groove 22 is formed on the surface of the second discharge pipe 21. A threaded post 23 extending out of the limiting groove 22 is fixedly connected to the surface of the first discharge pipe 20. A wing nut 24 is threadedly connected to the outer surface of the threaded post 23. By setting the first discharge pipe 20, the second discharge pipe 21, the limiting groove 22, the threaded post 23, and the wing nut 24, the length of the entire discharge pipe assembly 9 can be adjusted by sliding the second discharge pipe 21 on the outer surface of the first discharge pipe 20. By tightening the wing nut 24, the wing nut 24 can press the second discharge pipe 21, so that the first discharge pipe 20 and the second discharge pipe 21 can be relatively fixed, thereby adjusting the position of the discharge port to adapt to different feeding requirements.

[0030] The bottom of the material box 1 is a sloping surface that is high around the edges and low in the middle. This design allows the material to move towards the middle of the material box 1, effectively preventing material residue from remaining inside the material box 1.

[0031] Working principle: When the EPS foam production feeding device is in use, the material is first poured into the feeding box 1. Then, after loosening the locking bolt 12, the position of the discharge pipe assembly 9 can be adjusted by rotating the adjusting pipe 4. By tightening the locking bolt 12, the locking bolt 12 is inserted into the positioning hole 13, which can fix the adjusting pipe 4 and the discharge pipe assembly 9. This allows the operator to adjust the orientation of the discharge port of the discharge pipe assembly 9 as needed, providing convenience for the operator. Finally, the power motor 19 is turned on, and the power motor 19 drives the spiral auger 5 to rotate, which can transport the material inside the feeding box 1 from the feeding pipe 3 to the top of the adjusting pipe 4. Then, it is discharged from the discharge port of the discharge pipe assembly 9 through the first discharge hole 6 and the second discharge hole 8, thus realizing the feeding operation.
