The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0023] Please see Figures 1 to 2 An automatic feeding device for a granulator in this embodiment includes a base 1, a granulator body 2, and a storage box 3. A conveying cylinder 4 is fixed on the upper surface of the base 1 by a support frame. A first motor 5 is fixed on one side of the conveying cylinder 4. A conveying wheel 6 is rotatably connected inside the conveying cylinder 4 through a sealed bearing. One side of the conveying wheel 6 rotatably passes through the conveying cylinder 4 and is fixedly connected to the outside of the output shaft of the first motor 5. A filter assembly 7 is provided inside the storage box 3.

[0024] In this embodiment, a mounting bracket 8 is fixed on the right side of the upper surface of the base 1, and the storage box 3 is fixed on the upper surface of the mounting bracket 8. The upper surface of the storage box 3 is hinged to a box cover 9 via a hinge seat. A handle is fixed on the upper surface of the box cover 9. A conveying pipe 10 is connected to the left side of the lower surface of the conveying cylinder 4. The bottom end of the conveying pipe 10 is located inside the feed pipe of the granulator body 2. The conveying cylinder 4 includes a circular cylinder. A sealing cover is fixed to the right side of the circular cylinder by bolts. The sealing cover includes a fixed cover. A sealing rubber layer is fixed to the left side of the fixed cover.

[0025] Please see Figure 3In this embodiment, the filter assembly 7 includes fixing blocks 701 fixed to the left and right side walls of the inner cavity of the storage box 3. The upper surface of the left and right fixing blocks 701 is fixed with a filter screen 702 by bolts. Vibration structures 703 are provided on both the left and right sides of the storage box 3. A flow guide frame 704 is fixed inside the storage box 3. The bottom end of the flow guide frame 704 is connected to a connecting pipe 705. The bottom end of the connecting pipe 705 passes through the storage box 3 and extends to the lower side. The outer side of the bottom end of the connecting pipe 705 is connected to a solenoid valve 706. The inside of the solenoid valve 706 is connected to an output pipe 707. The mounting bracket 8 is provided with a connecting assembly. The filter screen 702 can be disassembled by twisting the bolts on the left and right sides of the upper surface of the filter screen 702.

[0026] Specifically, the first motor 5 drives the conveying wheel 6 to send the material into the granulator body 2 through the conveying pipe 10 to complete the feeding process. The electromagnetic valve 706 can precisely control the outflow of material and achieve precise control of the feeding amount, enabling automatic feeding. The vibration structures 703 on the left and right sides are synchronously controlled by the synchronous controller, and the vibration structures 703 on the left and right sides can vibrate synchronously.

[0027] Specifically, the connecting assembly includes a fixed cylinder 708 fixed inside the mounting frame 8, with a movable pipe 709 connected to the bottom end of the fixed cylinder 708. The left side of the movable pipe 709 is connected to the right side of the conveying cylinder 4. The vibration structure 703 includes a mounting frame, with a vibration motor fixedly installed inside the mounting frame. The bottom end of the top output pipe 707 of the fixed cylinder 708 is connected to the vibration structure 703 on both the left and right sides of the storage box 3. When the vibration motor in the vibration structure 703 is working, it will cause the storage box 3 to vibrate, improving the material flowability. After filtration and vibration-assisted flow, the material enters the conveying cylinder 4 through the guide frame 704, connecting pipe 705, solenoid valve 706, output pipe 707, fixed cylinder 708, and movable pipe 709. It should be noted that the filter screen 702 in the filter assembly 7 is fixed to the fixing blocks 701 on the left and right sides by bolts. When the material enters the storage box 3, the filter screen 702 will filter out the impurities in the material to ensure the purity of the material entering the conveying process and prevent impurities from entering the granulator body 2 and affecting the granulation quality.

[0028] The working principle of the above embodiments is as follows:

[0029] In operation, the material is first placed in the storage box 3. The filter assembly 7 inside the storage box 3 plays a key role. The filter screen 702 in the filter assembly 7 is fixed to the fixing blocks 701 on the left and right sides by bolts. When the material enters the storage box 3, the filter screen 702 will filter out the impurities in the material, ensuring the purity of the material entering the conveying process and preventing impurities from entering the granulator body 2 and affecting the granulation quality. At the same time, vibration structures 703 are set on both the left and right sides of the storage box 3. When the vibration motor in the vibration structure 703 works, it will cause the storage box 3 to vibrate, improving the material flow. After the material is filtered and vibrated to assist the flow, it enters the conveying cylinder 4 through the guide frame 704, connecting pipe 705, solenoid valve 706, output pipe 707, fixed cylinder 708 and movable pipe 709. Then, the first motor 5 drives the conveying wheel 6 to send the material into the interior of the granulator body 2 through the conveying pipe 10, completing the feeding process. The outflow of material can be precisely controlled by the solenoid valve 706, realizing precise control of the feeding amount.

[0030] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
