[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] A visual inspection feeding device with a four-channel material selection structure includes a main base 1, a material hopper 2, a feeding belt track 3, a first conveyor belt track 4, a second conveyor belt track 5, and a third conveyor belt track 6. The first, second, and third conveyor belt tracks 4, 5, and 6 are all located on the top surface of the main base 1, and the material hopper 2 is located on one side of the main base 1. The feeding belt track 3 is inclined, with its lower end connected to the material hopper 2 and its upper end connected to the first conveyor belt track 4.

[0029] The rubber cap material in the material hopper 2 is fed into the conveyor belt track 4 via the feeding belt track 3. To prevent the rubber cap material from falling off the feeding belt track 3, feeding baffles 7 are provided on both sides of the feeding belt track 3. Several belt surface protrusions 8 are provided on the track surface of the feeding belt track 3, which can effectively lift the rubber cap material. A material baffle 9 is provided on one side of the conveyor belt track 4, which can effectively prevent the rubber cap material from falling off the conveyor belt track 4. An inlet baffle 10 is provided at the material baffle 9, located at the front end of the conveyor belt track 4, which can effectively prevent the rubber cap material from falling out from the front end of the conveyor belt track 4.

[0030] One side of conveyor belt track 4 is a material baffle 9, and the other side is conveyor belt track 5 and conveyor belt track 6. The horizontal height of conveyor belt track 5 and conveyor belt track 6 is lower than that of conveyor belt track 4. As conveyor belt track 4 rolls, the rubber-capped material on conveyor belt track 4 can be introduced into conveyor belt track 5 and conveyor belt track 6. Material baffles 211 are provided on both sides of conveyor belt track 5, and material baffles 312 are provided on both sides of conveyor belt track 6. Material baffles 211 prevent the rubber-capped material from falling off the sides of conveyor belt track 5; material baffles 312 prevent the rubber-capped material from falling off the sides of conveyor belt track 6. In order to smoothly introduce the rubber-capped material from conveyor belt track 4 into conveyor belt track 5 and conveyor belt track 6 respectively, a guide plate 13 is provided at conveyor belt track 5. One end of the guide plate 13 is fixed to the material baffle 211, and the other end is located at the central axis of conveyor belt track 4. This design allows rubber-capped material inside conveyor belt track 4 to be introduced into conveyor belt track 5. A guide plate 2 14 is provided at material baffle 3 12, with one end fixedly connected to material baffle 3 12 and the other end fixedly connected to material baffle 9. This design also allows rubber-capped material outside conveyor belt track 4 to be introduced into conveyor belt track 6. To prevent rubber-capped material from leaking out of the gap between conveyor belt track 2 5 and conveyor belt track 6, a connecting baffle 15 is provided between conveyor belt track 2 5 and conveyor belt track 6.

[0031] A sorting head 16 is installed at the central axis of both conveyor belt track 2 (5) and conveyor belt track 3 (6). A sorting head frame 17 is installed at the rear end of both conveyor belt track 2 (5) and conveyor belt track 3 (6), with the sorting head 16 positioned at the frame 17. The lower surface of the sorting head 16 does not contact the belt surface of the corresponding conveyor belt track 2 (5) or conveyor belt track 3 (6). The sorting head 16 is bow-shaped, allowing the rubber cap material that collides with it to separate along its sides. The maximum width of the sorting head 16 is less than the belt surface width of conveyor belt track 2 (5) and conveyor belt track 3 (6). The two sorting heads are centrally located at conveyor belt track 2 (5) and conveyor belt track 3 (6), respectively. The width reserved on both sides of the sorting head 16 is exactly equal to or slightly greater than the maximum diameter of the rubber cap material. When the rubber cap material is placed face down on conveyor belt track 25 or conveyor belt track 36, the material is in a stable position and can pass smoothly through the gaps on both sides of the sorting head 16 without falling off. When the rubber cap material is in an unstable state (not face down), it will pass through the gaps on both sides of the sorting head 16 and be knocked off conveyor belt track 25 or conveyor belt track 36. To ensure the rubber cap material falls smoothly, there are no material baffles 211 and 312 on either side of the sorting head 16. Both sides of the material sorting head 16 are provided with raised strips 21. When the raised strips 21 collide with the unstable rubber cap material, they will knock the rubber cap material off the second conveyor belt track 5 or the third conveyor belt track 6. At the same time, there is an annular reserved groove on the waist side of the rubber cap material. When the rubber cap material is in a stable state, the raised strips 21 can pass through the annular reserved groove. The raised strips 21 can play the role of verifying the position and state of the rubber cap material.

[0032] A return hopper 18 is located at the main base 1, directly below the sorting head 16. Rubber caps falling from conveyor belt track 2 (5) and conveyor belt track 3 (6) fall directly into the return hopper 18. The lower opening of the return hopper 18 connects to the material hopper 2, and the rubber caps inside return to the material hopper 2. The rubber caps sorted by this device are placed in a stable state with their top surface facing down. Rubber caps in an unstable state return to the material hopper 2 for the next positional sorting. To facilitate the removal of the sorted rubber caps, a transmission belt track 4 (19) is connected to the rear ends of both conveyor belt track 2 (5) and conveyor belt track 3 (6). The sorted rubber caps are guided into the visual inspection equipment via the transmission belt track 4 (19). For smooth removal of the rubber caps, a discharge plate 20 is provided at each of the two head frames 17.

[0033] 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.
