[0025] In this embodiment, a stirring rod 17 is fixedly connected to the outer side of the transmission rod 5. The stirring rod 17 is arranged downwardly by rotating around the central axis of the transmission rod 5, and there are three stirring rods 17. The stirring rod 17 can stir the rubber inside the discharge box 2 to prevent the internal rubber from sticking together and forming blocks, which is not conducive to the outflow of the rubber. A plurality of groups of conveying blocks 16 are fixedly connected to the outer side of the conveyor belt 8, and the distance between every two conveying blocks 16 is the same. Under the action of the plurality of groups of conveying blocks 16, the rubber can be effectively prevented from rolling off during the upward tilting movement, thereby improving the transmission efficiency. A brush plate 21 is rotatably connected to the inner side of the support frame 1, and a torsion spring 22 is sleeved on the lower outer side of the brush plate 21, which can realize the brushing of the surface of the conveyor belt 8 and the conveying block 16, and the rubber adhering to the surface can be brushed off, thereby increasing the transmission efficiency. Example 2

[0026] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a feeding device for rubber processing, including a transmission rod 5, the bottom end of the transmission rod 5 is fixedly connected to a first rotating rod 9, the inside of the first rotating rod 9 is rotatably connected to a connecting rod 10, the outer side of the connecting rod 10 is rotatably connected to a second rotating rod 11, and the inside of the second rotating rod 11 is rotatably connected to a scraper 12.

[0027] In this embodiment, an annular groove 13 is provided at the bottom end of the discharge box 2, and a slider 14 is fixedly connected to one side of the scraper 12, and the cross-sectional area of ​​the slider 14 is the same as the cross-sectional area of ​​the annular groove 13, which is conducive to the sliding of the slider 14 inside the annular groove 13 and drives the scraper 12 to scrape the inner wall of the discharge hole 7 to prevent blockage. The two ends of the connecting rod 10 are connected to the limiting blocks 15, and the limiting blocks 15 at the top of the connecting rod 10 are embedded in the first rotating rod 9 to improve space utilization, and limit the first rotating rod 9 and the second rotating rod 11 to prevent falling during rotation. A feed hopper 18 is embedded in the top cover 3, and a groove 19 is provided on the outer side of the discharge box 2. An observation window 20 is embedded in the groove 19. The staff can observe the rubber stock inside the discharge box 2 through the observation window 20 to prevent the rubber from running out during feeding and reducing work efficiency.

[0028] Among them, the servo motor 4 and the conveyor belt 8 are prior art and will not be described in detail. At the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left and right" perspectives of the device are as follows: Figure 1 The direction shown in the figure is used as the reference.

[0029] Working principle: when the staff is feeding the rubber, they first fix the discharge box 2 on the top of the support frame 1, pour the rubber from the feed hopper 18 embedded in the top cover 3, and enter the storage slot 23 opened on the upper part of the discharge box 2, then cover the top cover 3, start the servo motor 4, so that the servo motor 4 drives the transmission rod 5 fixedly connected to the end of its output shaft to rotate, and the transmission rod 5 drives the stirring rod 17 fixedly connected to the outside to rotate to prevent the internal rubber from sticking into blocks, which is not conducive to the outflow of the rubber. The transmission rod 5 also drives the baffle plate 6 fixedly connected to the outside to move. When the baffle plate 6 rotates, the discharge hole 7 is opened and closed in sequence, so that a certain amount of rubber can be controlled to flow out of the discharge hole 7 to prevent excessive outflow at one time from causing blockage, reducing the transmission efficiency of the rubber, wasting the time and energy of the staff, and causing unnecessary economic losses. During this period, the transmission rod 5 drives the first rotating rod 9 fixedly connected to the bottom end to rotate. Under the action of the connecting rod 10 rotatably connected internally, the first rotating rod 9 makes the second rotating rod 11 rotatably connected to the outside of the connecting rod 10 rotate. The movable rod 11 drives the scraper 12 connected to the internal rotation to rotate. Under the action of the annular groove 13, the slider 14 slides inside it, so that the scraper 12 can scrape the inner wall of the discharge hole 7 to make the remaining rubber on the inner wall fall off, and prevent the rubber from adhering to the inner wall of the discharge hole 7 and causing excessive blockage. Under the action of the limit block 15, the first rotating rod 9 and the second rotating rod 11 can be limited to prevent them from falling during the rotation process. After the rubber falls to the conveyor belt 8 under the discharge box 2, the rubber is conveyed to the target position. In multiple groups of conveying blocks Under the action of 16, the rubber is prevented from rolling down during the upward tilting movement, thereby improving the transmission efficiency. When the conveyor belt 8 rotates to the position of the brush plate 21, the brush plate 21 can brush the surface of the conveyor belt 8 and the conveying block 16 under the action of the torsion spring 22, and brush off the rubber adhering to the surface, thereby increasing the transmission efficiency and reducing the probability of rubber clogging on the conveyor belt 8. During this period, the staff can observe the rubber inventory inside the discharge box 2 through the observation window 20 embedded in the groove 19 to prevent the rubber from running out and reducing work efficiency.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
