[0002] Currently, Chinese utility model patent CN209691731U discloses a feeding device with a protective structure for a chip sorting machine. While this feeding structure is securely fixed and easy to connect to the bottom of the sorting machine, it has other problems during use. For example, it provides poor protection for the product. When the product rolls down the frame wall from a height, it generates strong kinetic energy; or when it falls directly from the center, it generates a strong impact force. If the impact force is not buffered in time, it will collide after falling, easily causing wear and tear on the product. Furthermore, it lacks impurity removal and filtration functions. During the product's falling process, a large amount of dust and debris is generated, and these impurities fall into the collection box along with the product, increasing the subsequent cleaning burden on personnel. To solve the above problems, we propose a feeding structure for a roller sorting machine. Utility Model Content

[0005] By adopting the above technical solution, the protective effect on the product can be improved, the kinetic energy accumulated when the product falls can be eliminated, the safety and quality of the product can be guaranteed, and at the same time, it can have the function of removing impurities and filtering, collecting the impurities separated when the product falls separately, improving the cleanliness of the product and making it highly practical.

[0006] The present invention is further configured such that: a limiting rod is symmetrically welded on one side of the protective plate, and the other end of the limiting rod passes through and extends to the outside of the outer frame.

[0007] By adopting the above technical solution, the protective plate can be limited by the setting of the limiting rod, so as to prevent the protective plate from tilting when it moves inward after being hit.

[0008] The present invention is further configured such that a rubber pad is bolted to the other side of the protective plate.

[0009] By adopting the above technical solution and setting up rubber pads, the product can be protected and scratches can be avoided when the product is hit.

[0010] The present invention is further configured such that: a mounting plate is installed on one side of the outer frame, and the mounting plate has mounting holes inside.

[0011] By adopting the above technical solution, the mounting plate and mounting holes make it easy for personnel to fix the outer frame to the bottom of the sorting machine with screws.

[0012] The present invention is further configured such that: both sides of the filter screen are fitted with a retainer, and the other side of the two retainers are respectively bolted to the filter box and the outer frame.

[0013] By adopting the above technical solution, the filter screen can be limited by the setting of the card holder, so as to prevent the filter screen from shifting or falling off.

[0017] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the outer frame and guide frame surfaces can be improved.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model first fixes the outer frame to the bottom of the sorting machine with screws. After the outer frame is fixed, the rollers after sorting will roll down with the inclined surface of the outer frame and hit the rubber pad. When the rubber pad is hit, it will drive the protective plate to move backward and press the fixed spring and damper. When the fixed spring and damper contract and deform, they will absorb and cancel the force. After the rollers are buffered by energy reduction, they will be discharged from the discharge port. This can improve the protection effect of the product, eliminate the kinetic energy accumulated when the product falls, and ensure the safety and quality of the product.

[0020] 2. This utility model, by activating the suction fan, draws impurities and particulate matter into the fixed cover through the guide frame and suction holes. Subsequently, the impurities in the fixed cover enter the external filter box through the fixed pipe. The filter screen in the filter box intercepts the impurities and particulate matter, and the filtered gas is discharged from the lower air outlet. It has a purification and filtration function, and collects the impurities separated when the product falls separately, improving the cleanliness of the product and making it highly practical.
