[0019] See also Figures 1-4, this embodiment provides a technical solution: a disc automatic feeder, which includes a frame 1. The base of the frame 1 is rotatably connected to a feeding disc 3 through a rotating shaft 2. A second bevel gear 9 is fixed to the bottom of the feeding disc 3. A speed reducer 13 and a stepping motor 14 are respectively installed on the support frame of the frame 1. The output shaft of the stepping motor 14 is fixedly connected to the input end of the speed reducer 13. A first bevel gear 12 is fixed to the output shaft of the speed reducer 13. The first bevel gear 12 is in tooth engagement with the second bevel gear 9. A lifting mechanism 4 is installed on the base of the frame 1. A lubricating grease storage box 6 is fixed to the lifting end of the lifting mechanism 4. A lubricating grease extrusion structure 5 is installed inside the lubricating grease storage box 6. The coating surface of the lubricating grease storage box 6 coincides with the surface of the first bevel gear 12. Through holes 7 are evenly opened on the coating surface of the lubricating grease storage box 6. A PLC controller 15 is installed on the side of the support frame of the frame 1. The PLC controller 15 is electrically connected to an external power supply. The stepping motor 14 is electrically connected to the PLC controller 15. The output shaft of the stepping motor 14 drives the input shaft of the speed reducer 13 to rotate. The output shaft of the speed reducer 13 drives the first bevel gear 12 to rotate. The first bevel gear 12 and the second bevel gear 9 are in meshing transmission. The second bevel gear 9 drives the feeding disc 3 to rotate. The feeding disc 3 rotates relative to the frame 1 through the rotating shaft 2. This is prior art and this solution only briefly describes it.

[0020] The lifting mechanism 4 includes an ear seat 41 and a cylinder 42. The cylinder 42 is installed on the top of the base of the frame 1. The ear seat 41 is fixed to the telescopic end of the cylinder 42. The ear seat 41 is fixed to the side of the lubricating grease storage box 6. The cylinder 42 is electrically connected to the PLC controller 15. The lubricating grease extrusion structure 5 includes a transmission seat 51, a push rod 52 and an extrusion plate 53. The extrusion plate 53 is slidably arranged inside the lubricating grease storage box 6. The push rod 52 is fixed to the bottom of the extrusion plate 53 and is vertically movably connected to the lubricating grease storage box 6. The transmission seat 51 is fixed to the bottom end of the push rod 52. The lubricating grease extrusion structure 5 further includes a servo motor 54 and a lead screw 55. The servo motor 54 is installed on the side of the lubricating grease storage box 6. The lead screw 55 is fixed to the output shaft of the servo motor 54. The lead screw 55 is threadedly connected to the transmission seat 51. The servo motor 54 is electrically connected to the PLC controller 15. When it is necessary to lubricate the gear, the output shaft of the servo motor 54 drives the lead screw 55 to rotate. The lead screw 55 is in threaded transmission with the transmission seat 51. The transmission seat 51 drives the push rod 52 to perform a lifting motion. The end of the push rod 52 drives the extrusion plate 53 to lift. The extrusion plate 53 presses the lubricating grease in the lubricating grease storage box 6 into the position of the through hole 7. Then, the telescopic end of the cylinder 42 drives the lubricating grease storage box 6 to perform a lifting motion through the ear seat 41, so that the lubricating grease at the through hole 7 contacts the surface of the first bevel gear 12. When the first bevel gear 12 rotates, the lubricating grease is coated on its surface. At the same time, the first bevel gear 12 meshes with the second bevel gear 9 in tooth. Therefore, the lubricating grease on the first bevel gear 12 can be transferred to the second bevel gear 9. It is convenient for coating the lubricating grease, avoiding the trouble of manual coating, saving time and effort, and having good use safety.

[0021] It further includes a cotton strip 8. The cotton strips 8 are evenly arranged on the coating surface of the lubricating grease storage box 6. Part of the lubricating grease will adhere to the cotton strips 8 during the coating process, and the lubricating grease is further evenly smeared through the cotton strips 8.

[0022] It further includes an adding pipe 10. The adding pipe 10 is connected and fixed to the side of the lubricating grease storage box 6. A switching valve 11 is fixed at the connection of the adding pipe 10 and the lubricating grease storage box 6. When the switching valve 11 is opened, lubricating grease is added into the lubricating grease storage box 6 through the adding pipe 10, ensuring the rationality of the design.

[0023] The working principle of a disc automatic feeder provided by the present utility model is as follows: The output shaft of the stepper motor 14 drives the input shaft of the speed reducer 13 to rotate. The output shaft of the speed reducer 13 drives the first bevel gear 12 to rotate. The first bevel gear 12 is in meshing transmission with the second bevel gear 9. The second bevel gear 9 drives the feed tray 3 to rotate. The feed tray 3 rotates relative to the frame 1 through the rotating shaft 2. This is prior art, and only a simple description is given in this solution. When lubrication of the gears is required, the output shaft of the servo motor 54 drives the lead screw 55 to rotate. The lead screw 55 is in threaded transmission with the transmission seat 51. The transmission seat 51 drives the push rod 52 to perform a lifting motion. The end of the push rod 52 drives the pressing plate 53 to lift. The pressing plate 53 presses the lubricating grease in the lubricating grease storage box 6 into the position of the through hole 7. Then, the telescopic end of the cylinder 42 drives the lubricating grease storage box 6 to perform a lifting motion through the ear seat 41, so that the lubricating grease at the through hole 7 contacts the surface of the first bevel gear 12. When the first bevel gear 12 rotates, the lubricating grease is coated on its surface. At the same time, since the first bevel gear 12 is in meshing with the second bevel gear 9, the lubricating grease on the first bevel gear 12 can be transferred to the second bevel gear 9. Part of the lubricating grease will adhere to the cotton strip 8 during the coating process, and the cotton strip 8 further evenly applies the lubricating grease. The switch valve 11 is opened, and lubricating grease is added to the lubricating grease storage box 6 through the adding pipe 10.
