[0038] Working principle: Before using this plastic pellet feeding device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, initially, the raw materials in the material pocket pass through the guide tube 102 and the inner sleeve 209 into the outer sleeve 207 and are lifted by the rotating support plate 218. Then, the motor 302 is started to make the circular plate 303 push and pull the connecting rod 304, so that the rack 305 drives the gear 306 to rotate, and then the bottom plate 205 and the top plate 208 rotate to the discharge port 101 and discharge the materials. As the rotation speed of the motor 302 changes, the feeding gap also changes. However, the volume of each feeding is fixed to the volume of the cylindrical space from the top surface of the top plate 208 to the surface of the rotating support plate 218. Ultimately, simply changing the feeding speed increases the practicality of the equipment.

[0039] By starting the electric push rod 211, the bottom plate 205 and the control sleeve 213 are synchronously raised, thereby increasing the height of the outer sleeve 207 and the rotating support plate 218, thereby reducing the volume of the cylindrical space from the top surface of the top plate 208 to the surface of the rotating support plate 218, and then changing the amount of raw materials entering the inner sleeve 209 through the guide tube 102. After the volume of the cylindrical space is fixed, the amount of material added each time is fixed, thereby achieving quantitative feeding;

[0040] When the bottom plate 205 rotates, the sliding block 219 slides in the annular groove 214. When the sliding block 219 enters the convex groove 215, the rotating support plate 218 rotates and separates from the bottom of the outer sleeve 207, so that the raw materials in the outer sleeve 207 can fall into the guide plate 103. As the sliding block 219 moves, the rotating support plate 218 is completely opened and then slowly closed, so that all the internal raw materials fall onto the guide plate 103, realizing automatic feeding.

[0041] During the process of rotating and opening the rotating support plate 218, the guide plate 103 will be pressed to rotate, and after the rotating support plate 218 is separated from the guide plate 103, the torsion spring 105 will pull the guide plate 103 to tilt further, thereby increasing the bevel angle of the guide plate 103, thereby promoting the rolling of the raw material.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
