[0025] Referring to Figures 1 to 4 , an embodiment of a ball feeding mechanism is proposed:

[0026] A ball feeding mechanism comprises a silo 1 for storing balls, and a lifting rod 2 penetrating the silo 1 in the vertical direction. The bottom of the silo 1 is provided with a first blowing device for blowing the balls. The top of the lifting rod 2 is connected with a suction nozzle 21 for negatively adsorbing the blown balls, and the lifting rod 2 is used for lifting the balls to above the silo 1.

[0027] The utility model blows the ball pile through the first blowing device, and the ball pile is blown away for the tiny ball, and the ball pile is blown away for the tiny ball.

[0028] As Figure 4 shown, the lifting rod 2 comprises a vertical air pipe 22 penetrating the bottom of the silo 1, a lifting cylinder 4 located below the silo 1, the outer surface of the vertical air pipe 22 is in transmission connection with the output end of the lifting cylinder 4, the upper end of the vertical air pipe 22 is connected with the suction nozzle 21, the lower end of the vertical air pipe 22 is connected with the air extraction device, and the air extraction device enables the suction nozzle 21 to be in a negative pressure state.

[0029] The air extraction device includes a throttle valve 23 and a connecting pipe 24 connecting the throttle valve and the lower end of the vertical air pipe 22. Two first nuts 241 are integrally formed on the outside of the connecting pipe 24, spaced apart vertically. Specifically, the lifting cylinder 4 is a sliding cylinder, and its output end is fixedly connected to the connecting pipe 24 via a T-shaped connecting seat 26. The T-shaped connecting seat 26 includes a horizontally extending first connecting portion 261 and a vertically extending second connecting portion 262. The first connecting portion 261 is fixedly connected to the output end of the lifting cylinder 4. One end of the second connecting portion 262 is integrally formed with the first connecting portion 261, and the other end of the second connecting portion 262 has a connecting opening 263. The connecting pipe 24 is placed within the connecting opening 263 between the two first nuts 241, and the two first nuts 241 are respectively tightened above and below the second connecting portion 262, thus fixing the T-shaped connecting seat 26 to the connecting pipe 24.

[0030] To ensure more stable lifting of the lifting rod 2, a guide base 41 is fixedly connected to the bottom of the hopper 1. The guide base is equipped with a slide rail 42 extending vertically, and a slider 43 is slidably connected to the slide rail 42. One end of the slider 43 is slidably connected to the slide rail 42, and the other end of the slider 43 is fixedly connected to a connecting plate 44. The connecting plate 44 has a pipe hole for the vertical air pipe 22 to pass through. A second nut 221 is provided on the outer surface of the vertical air pipe 22, and the vertical air pipe 22 tightens the connecting plate 44 with the second nut and the first nut 241.

[0031] like Figure 2 As shown, the hopper 1 includes a material barrel 11, which has a material cavity for placing spheres. The top of the material barrel 11 is open and connected to a lid 12. A lid protrusion 13 is located at the center of the top of the lid 12. The lid protrusion 13 has a feeding channel 14 communicating with the material cavity. A second air blowing device 15 is connected to the lid protrusion 13 for blowing air into the feeding channel 14. The diameter of the feeding channel 14 is smaller than the diameter of the material cavity, but larger than the diameter of the vertical air pipe 22. The smaller diameter of the feeding channel 14 allows the second air blowing device 15 to concentrate airflow onto the outer surface of the vertical air pipe 22, causing the spheres on the outer surface of the vertical air pipe 22 to fall off.

[0032] The feeding channel 14 is equipped with a material partition 16. The material partition 16 is provided with an air pipe through hole for the vertical air pipe 22 to pass through. The gap between the air pipe through hole and the vertical air pipe 22 is smaller than the diameter of the spherical material. The second air blowing device is used to blow air onto the vertical air pipe 22 below the material partition 16.

[0033] The lid 12 is provided with an air vent 121.

[0034] The material cavity comprises a straight barrel cavity 17 and a conical cavity 18, the upper end of the conical cavity 18 communicates with the lower end of the straight barrel cavity 17, the diameter of the conical cavity 18 gradually decreases from top to bottom, the barrel 11 is provided with a blowing hole 181 located in the conical cavity 18, and the first blowing device blows air to the material cavity through the blowing hole 181.

[0035] As shown in Figure 3 The ball feeding mechanism further comprises a material translation device 5 located outside the hopper 1, and the material translation device 5 is used to move the ball jacked above the hopper 1 to the next station.

[0036] The material translation device 5 comprises a motor 51, the output shaft of the motor 51 is in driving connection with the center of a feeding impeller 52, the motor 51 is used to drive the feeding impeller 52 to rotate in the vertical direction as the rotation shaft, the feeding impeller 52 comprises a plurality of unit blades 521 uniformly arranged in the circumferential direction, and the end of the unit blade 521 away from the feeding impeller 52 is provided with a clamping hole 522 matched with the ball.

[0037] The ball feeding process of the utility model is as follows:

[0038] Firstly, the lifting cylinder 4 drives the lifting rod 2 to descend, so that the suction nozzle 21 is located in the straight barrel cavity 17. Then the first blowing device blows air to the conical cavity 18, so that the ball piles in the conical cavity 18 are blown apart and the ball is blown up. Then the suction nozzle 21 of negative pressure is attached to one of the balls. Since the volume of the ball is small and the mass is light, and in the process of blowing the ball, static electricity is generated by the friction between the balls, so that the ball is adsorbed on the surface of the lifting rod 2.

[0039] After the suction nozzle 21 sucks the ball, the lifting cylinder 4 drives the lifting rod 2 to rise, the lifting rod 2 passes through the feeding channel 14, the second blowing device blows air downward to the lifting rod 2 in the feeding channel 14, so that the ball on the surface of the lifting rod 2 is blown off, then the lifting rod 2 passes through the air pipe through hole, and the material partition plate 16 further scrapes the ball on the surface of the lifting rod 2, so that the ball is not adsorbed on the surface of the lifting rod 2 and cannot be fed. Finally, the lifting rod 2 jacks the ball above the hopper 1, and the ball is conveyed into the clamping hole 522 of the unit blade 521. The motor 51 drives the feeding impeller 52 to rotate in the vertical direction as the rotation shaft, the unit blade 521 moves the ball to the next station, and another unit blade 521 without the ball rotates above the hopper 1.

[0040] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, direct or indirect application in other related technical fields according to the contents of the utility model specification and drawings are also included in the patent protection range of the utility model.
