Specific implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-7 , the present invention provides a technical solution: a feeding device for an optical screening machine to prevent blockage of the discharge port, including a material cylinder 1, a discharge cylinder 2, a discharge port 3, a baffle 4, a fixing block 5, a fixing hole 6, a movable support 7, a fixing plate 8, a spring 9, a fixing rod 10, a fixing cap 11, a fixing groove 12, a motor 13, an anti-blocking mechanism 14, an eccentric wheel 15, a movable frame 16, a movable column 17 and a discharge plate 18.

[0034] When using the feeding device for the optical screening machine to prevent blockage of the discharge port, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the lower end of the material cylinder 1 is fixedly connected to the discharge cylinder 2, and a discharge port 3 is opened at the right end of the discharge cylinder 2. At the same time, the baffle 4 is attached to the right end of the discharge cylinder 2. The material cylinder 1 is connected to an external optical screening machine (not shown in the figure). First, add materials to the material cylinder 1, and then according to the actual requirements for the feeding rate, by pulling the movable support 7 to the left, the movable support 7 moves in the fixing plate 8, and the movable support 7 squeezes the spring 9, causing the spring 9 to undergo elastic deformation. At the same time, the upper end of the left side of the movable support 7 is fixedly connected to a fixing rod 10, and the fixing rod 10 is connected to the fixing plate 8 in a card slot manner. The movable support 7 drives the movement between the fixing rod 10 and the fixing plate 8. At this time, the right end of the movable support 7 is pulled out from the fixing hole 6, and then the;

[0035] Then, by pulling the baffle 4 upward, the baffle 4 slides between the fixed blocks 5. At this time, the material is fed into the optical screening machine through the discharge port 3. And by the distance of the up-and-down telescopic movement of the baffle 4 at the right end of the discharge cylinder 2, the opening size of the discharge port 3 can be adjusted, so as to realize the adjustment of the discharge rate. When it moves to the appropriate position, directly release the movable bracket 7. At this time, the spring 9 restores its elastic deformation and pushes the movable bracket 7 to be inserted into the fixing hole 6 at the corresponding position to limit between the baffle 4 and the discharge cylinder 2. Then, the fixing cap 11 screwed on the outer surface of the fixed rod 10 can also be rotated to make the fixing cap 11 move downward and engage in the fixing groove 12, so as to facilitate the locking between the movable bracket 7 and the fixing plate 8 and prevent the baffle 4 from slipping due to accidental contact with the movable bracket 7;

[0036] Combined with Figure 6 and Figure 7 As shown, during the actual feeding process, through the setting of the anti-blocking mechanism 14, the anti-blocking mechanism 14 includes an eccentric wheel 15 fixedly connected to the output end of the motor 13, a movable frame 16 sleeved outside the eccentric wheel 15, a movable column 17 for connection, and a discharge plate 18 with an inclined upper surface;

[0037] Start the motor 13 installed at the lower left end of the discharge cylinder 2. The motor 13 drives the eccentric wheel 15 to rotate in the movable frame 16. The eccentric wheel 15 is attached to the inner side wall of the movable frame 16, so that the movable frame 16 drives the movable column 17 to slide up and down between the discharge cylinder 2. The movable column 17 drives the discharge plate 18 to perform up-and-down telescopic movement at the bottom of the discharge cylinder 2, so that the discharge plate 18 vibrates in the discharge cylinder 2. And the upper surface of the discharge plate 18 is inclined. At this time, the material in the discharge cylinder 2 can pass through the discharge port 3 more smoothly for storage through vibration, preventing the material from being blocked. Moreover, the discharge plate 18 is attached to the inner side wall of the discharge cylinder 2, and there is no gap between the discharge plate 18 and the discharge cylinder 2, so as to prevent the problem of material jamming.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
