Description

Technical Field

[0001] This utility model relates to the field of conical twin extruder technology, specifically to a feeding device for a conical twin extruder. Background Technology

[0002] The conical twin-screw extruder is a highly efficient mixing and extrusion equipment. It features a low shear rate, minimal material decomposition, uniform plasticizing and mixing, stable quality, high output, wide applicability, and long service life.

[0003] A feeding device for a conical twin-screw extruder, with announcement number CN219446058U, uses a diamond-shaped rod to inject the raw materials required for processing sheet material from the feed funnel. It also activates a second drive motor, driving the drive roller to rotate. The meshing of the internal gear disc, gear one, and gear two allows the drive roller and internal gear disc to rotate in opposite directions, thus breaking up the raw material through the rotation of the diamond-shaped rod.

[0004] There are some shortcomings in its use. When using it, the raw material will adhere to the surface of the diamond rod, and it cannot be removed from the surface of the diamond rod in time. This will reduce the sharpness of the diamond rod and also lead to waste of raw material, which limits the practicality of the feeding device. At the same time, when the diamond rod rotates to break up the raw material, there will be dead corners in the breaking up, which will prevent the broken raw material from being screened again and will also cause the discharge head to be blocked later.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0025] A feeding device for a conical twin extruder includes a base plate 1, an extruder body 3 fixedly connected to the top of the base plate 1, a feeding box 5 fixedly connected to the top of the extruder body 3, the feeding box 5 communicating with the extruder body 3, a screen 17 slidably connected inside the feeding box 5, a side cover 6 fixedly connected to the side end of the screen 17, the side cover 6 being disposed outside the feeding box 5, a second magnetic plate 20 fixedly connected to the inner wall of the side cover 6, a groove 18 being formed inside the feeding box 5, a first magnetic plate 19 fixedly connected inside the groove 18, the second magnetic plate 20 being positioned opposite to the first magnetic plate 19, the magnetic poles of the second magnetic plate 20 and the first magnetic plate 19 being different at their proximal ends, an electric telescopic rod 7 fixedly connected to the top of the feeding box 5, and a top plate 8 fixedly connected to the bottom of the electric telescopic rod 7.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, a cone rod 9 is fixedly connected to the bottom of the top plate 8, and the cone rod 9 is positioned opposite the screen 17. A side plate 12 is fixedly connected to the outside of the feeding box 5. A movable plate 13 is slidably connected inside the side plate 12. A rectangular plate 14 is fixedly connected to the top of the movable plate 13. A brush 15 is fixedly connected inside the rectangular plate 14. The rectangular plate 14 is located on the side of the cone rod 9. A rack 11 is fixedly connected to the bottom of the movable plate 13. A drive motor 10 is installed on the outside of the feeding box 5. A gear 16 is fixedly connected to the output end of the drive motor 10.

[0027] The electric telescopic rod 7 can drive the cone rod 9 downward to disperse the raw materials and prevent them from clumping. At the same time, the drive motor 10 drives the rectangular plate 14 and the brush 15 to move. The movement of the brush 15 can make the raw materials attached to the surface of the cone rod 9 fall off, which can prevent the waste of raw materials and improve the cleanliness of the surface of the cone rod 9, making it easier for the cone rod 9 to be used normally next time.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, both gear 16 and rack 11 are made of stainless steel. Gear 16 is located at the bottom of rack 11 and meshes with rack 11. Support base 2 is fixedly connected to the bottom of base plate 1. Anti-slip texture is provided on the bottom of support base 2. Support base 2 is T-shaped. Discharge pipe 4 is fixedly connected to the side of extruder body 3. Discharge pipe 4 is connected to extruder body 3. Multiple brushes 15 are provided. Multiple brushes 15 are evenly distributed in rectangular plate 14. The size of multiple brushes 15 is the same.

[0029] The screen 17 can be fixed inside the feed box 5 by the magnetic attraction between the first magnetic plate 19 and the second magnetic plate 20. The screen 17 can then screen the dispersed raw material again, keeping large clumps of raw material on the surface of the screen 17 and preventing the clumps from entering the extruder body 3 and causing blockage inside the extruder body 3.

[0030] The working process of this utility model is as follows: When the feeding device for the conical twin extruder designed in this scheme is in operation, the raw material is placed in the feeding box 5. Then, the top plate 8 and the conical rod 9 are moved downward by the electric telescopic rod 7. The conical rod 9 breaks up the clumps of raw material and screens the raw material through the screen 17 to prevent the unbroken clumps of raw material from entering the extruder body 3. When the surface of the conical rod 9 is covered with raw material, the drive motor 10 drives the gear 16 to rotate. Since the gear 16 and the rack 11 mesh, the rectangular plate 14 and the brush 15 can be moved. The movement of the brush 15 can make the raw material attached to the surface of the conical rod 9 fall into the extruder body 3, so that the surface of the conical rod 9 is clean and the conical rod 9 can be used normally next time. At the same time, when it is necessary to remove the screen 17, the side cover 6 is pulled to separate the first magnetic plate 19 and the second magnetic plate 20, so that the screen 17 can be easily removed. The unbroken clumps of raw material are removed and extruded by the extruder body 3 and discharged through the discharge pipe 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
