[0020] Such as Figures 1-4As shown in the figure, a chain plate type metering feeder includes a base 12. Two pairs of brackets 13 are fixedly installed and connected to the base 12. A driving shaft is rotatably installed on a pair of brackets 13. A driving roller 7 is fixedly connected to the driving shaft. A driven shaft is rotatably installed on the other pair of brackets 13. A driven roller 10 is fixedly connected to the driven roller 10. The driving roller 7 and the driven roller 10 are connected by a chain plate 8. A plurality of driving rollers are provided at the bottom of the chain plate 8. The driving roller 7 and the driven roller 10 are provided with notches that cooperate with the driving rollers of the chain plate 8, so that the chain plate 8 rotates under the action of the driving roller 7 and the driven roller 10. A weighing sensor is provided at the bottom of the chain plate 8, which can weigh the materials on the chain plate 8, thereby controlling the metering feeding of the materials;

[0021] Baffles 9 are installed on both sides of the chain plate 8. The baffles 9 can prevent the materials from falling from both sides during the transmission process on the chain plate 8, and prevent the phenomenon of material waste.

[0022] One end of the driving shaft extends out of the bracket 13 and is fixedly connected with a second sprocket 1. A driving mechanism 6 that cooperates with the second sprocket 1 is fixedly installed on the base 12 on one side of the driving roller 7. The driving mechanism 6 can drive the driving roller 7 to rotate through the second sprocket 1 and the driving shaft, thereby realizing the movement of the chain plate 8.

[0023] The driving mechanism 6 is connected with a cleaning mechanism 11. The cleaning mechanism 11 is used to clean the residual materials on the surface of the chain plate 8, to avoid the materials getting stuck on the surface of the chain plate 8, and keep rotating repeatedly. The gravity sensor keeps weighing repeatedly, but the materials are not fed out, which will make the obtained material weight smaller, and the longer the running time, the greater the error will be.

[0024] The driving mechanism 6 includes a driving motor 2. The driving motor 2 is fixedly connected to the base 12. A driving shaft 4 is installed at the output end of the driving motor 2. A first sprocket 3 that cooperates with the second sprocket 1 is installed on the driving shaft 4. The driving motor 2 drives the first sprocket 3 to rotate through the driving shaft 4. The first sprocket 3 drives the second sprocket 1 to rotate through a chain. The second sprocket 1 drives the driving roller 7 to rotate through the driving shaft; A third sprocket 5 is fixedly connected to the driving shaft 4. The third sprocket 5 is connected to the cleaning mechanism 11;

[0025] The cleaning mechanism 11 includes a mounting frame. A cleaning shaft 16 is installed on the mounting frame. A brush 15 that cooperates with the chain plate 8 is fixedly connected to the cleaning shaft 16. One end of the cleaning shaft 16 extends out of the mounting frame and is fixedly connected with a locking mechanism 14. The cleaning shaft 16 passes through the locking mechanism 14. A fourth sprocket 17 is provided on the locking mechanism 14.

[0026] When the locking mechanism 14 does not lock the fourth sprocket 17, the fourth sprocket 17 can rotate relative to the cleaning shaft 16. The locking mechanism 14 can lock the fourth sprocket 17 on the locking mechanism 14, making the fourth sprocket 17 fixed relative to the cleaning shaft 16. The fourth sprocket 17 can drive the third sprocket 5 to be connected to the fourth sprocket 17 through a chain. The driving mechanism 6 drives the cleaning shaft 16 to rotate through the third sprocket 5 and the fourth sprocket 17, so that the brush 15 rotates to clean the chain plate 8. A recovery groove is arranged at the bottom of the brush 15, and the materials washed from the chain plate 8 are recovered by the recovery groove. After each quantitative feeding is completed, the materials in the recovery groove are transferred to the given materials, making the accuracy of quantitative feeding higher.

[0027] The locking mechanism 14 includes a mounting plate 20. The mounting plate 20 is fixedly connected to the cleaning shaft 16, and the cleaning shaft 16 penetrates through the mounting plate 20. A housing 19 is fixedly connected to the mounting plate 20. A rotating tube 28 is rotatably sleeved on the cleaning shaft 16 located inside the housing 19. A ratchet 26 is fixedly installed at the top of the rotating tube 28. The ratchet 26 is rotatably connected to the cleaning shaft 16. A control rod 24 is installed on the rotating tube 28. The housing 19 is provided with a hole matching the control rod 24. A number of hinge brackets 21 are fixedly connected to the housing 19. A locking buckle 22 is hingedly connected to each hinge bracket 21. A pressure rod 23 is hingedly connected to the locking buckle 22. The pressure rod 23 penetrates through the housing 19, and the end of the pressure rod 23 away from the locking buckle 22 abuts against the ratchet 26. The cleaning shaft 16 penetrates through the housing 19 and is rotatably connected to a locking disc 18. The locking disc 18 is fixedly connected to the fourth sprocket 17 through a sleeve.

[0028] When the control rod 24 rotates to fit with one side of the hole on the housing 19, the pressure rod 23 abuts against the highest point of the ratchet 26. At this time, the locking buckle 22 rotates along the hinge bracket 21, and the top of the locking buckle 22 presses the locking disc 18, making the locking disc 18 and the housing 19 relatively fixed, so that the fourth gear can drive the cleaning shaft 16 to rotate. When the control rod 24 rotates to fit with the other side of the hole on the housing 19, the pressure rod 23 abuts against the lowest point of the ratchet 26, and the locking buckle 22 opens. The locking disc 18 and the housing 19 slide relative to each other, making the fourth sprocket 17 unable to drive the cleaning disc to clean when rotating.

[0029] The mounting plate 20 is provided with a limit hole matching the control rod 24. A fixing rod 27 matching the control rod 24 is installed in the limit hole. The fixing rod 27 includes a bolt and a nut. The bolt passes through the limit hole and is fixed by the nut, so that the position of the control rod 24 is fixed.

[0030] In summary, during actual use, start the drive motor 2, evenly place the materials on the chain plate 8 for transportation. When it is found that there is obvious material adhering to the surface of the chain plate 8 and quantitative transportation cannot be carried out, control the control rod 24 to lock the locking disc 18 with the housing 19, so that the fourth sprocket 17 can drive the cleaning shaft 16 to rotate, enabling the brush 15 to clean the surface of the chain plate 8, and moving the cleaned materials into the output materials, making the weighing of the materials more accurate.

[0031] The specific implementation manners of the present utility model described above do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
