Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-2 , this embodiment provides a technical solution: a can lid stamping machine, including a stamping frame 1 and a stamping drive mechanism 3;

[0021] Stamping frame 1: A stamping chamber 5 is arranged inside it. A stamping seat 2 is slidably connected inside the stamping chamber 5. A stamping die 4 is arranged at the lower end of the stamping seat 2. A control switch group 14 is arranged in the middle of the left side surface of the stamping frame 1. The input end of the control switch group 14 is electrically connected to an external power source. Both the left and right ends of the stamping chamber 5 are fixedly connected with sliding columns 6. Both the left and right ends of the upper surface of the stamping seat 2 are fixedly connected with sliding seats 7. The inside of the sliding seats 7 are all slidably connected to the outer surfaces of the longitudinally adjacent sliding columns 6;

[0022] Stamping drive mechanism 3: It includes a drive shaft 32, drive gears 33, connecting shafts 34, connecting rods 35 and a drive seat 36. The drive shafts 32 are all rotatably connected to the upper ends of the rear side surfaces of the stamping chambers 5. The front ends of the drive shafts 32 are fixedly connected with drive gears 33. The two drive gears 33 are meshed and connected. The front ends of the drive gears 33 are fixedly connected with connecting shafts 34. The middle parts of the connecting shafts 34 are rotatably connected with connecting rods 35. The upper ends of the stamping seats 2 are fixedly connected with a drive seat 36. The lower ends of the connecting rods 35 are all rotatably connected to the upper ends of the drive seat 36. The stamping drive mechanism 3 further includes a motor 31. The motor 31 is arranged at the upper end of the rear side surface of the stamping frame 1. The output shaft of the motor 31 is fixedly connected to the rear end of the longitudinally adjacent drive shaft 32. The input end of the motor 31 is electrically connected to the output end of the control switch group 14. By the control switch group 14, the operation of the motor 31 is realized. The rotation of the output shaft of the motor 31 drives the longitudinally adjacent drive shaft 32 to rotate. The rotation of the drive shaft 32 drives the longitudinally adjacent drive gears 33 to rotate. The rotation of the left drive gear 33 drives the rotation of the right drive gear 33, thereby driving both connecting shafts 34 to rotate around the central axis of the longitudinally adjacent drive shaft 32. The rotation of the connecting shafts 34 drives the upper ends of the longitudinally adjacent connecting rods 35 to rotate around the central axis of the longitudinally adjacent drive shaft 32. When the upper ends of the connecting rods 35 rotate downward, the lower ends of the two connecting rods 35 both push the same drive seat 36 downward, thereby causing the stamping seat 2 to move downward under the guiding action of the sliding columns 6, and finally driving the stamping die 4 to move downward. The stamping die 4 and the support table 8 cooperate to work to realize the stamping and forming of the can lids. The stamped and formed can lids all fall onto the upper end of the electric conveyor belt 11 through the vertically corresponding grooves 9. The control switch group 14 realizes the operation of the electric conveyor belt 11 and the electric conveyor belt 13. The electric conveyor belt 11 conveys the stamped and formed can lids to the upper end of the electric conveyor belt 13, and then conveys them to the next working area through the electric conveyor belt 13. When the upper ends of the connecting rods 35 rotate upward, the lower ends of the two connecting rods 35 both pull the same drive seat 36 upward, thereby causing the stamping seat 2 to move upward under the guiding action of the sliding columns 6, and finally driving the stamping die 4 to move upward. Then the external moving platform adjusts the position of the raw material plate to perform the stamping and forming of the next batch of can lids. In this cycle, the up and down reciprocating movement of the stamping die 4 is realized, and the continuous stamping and forming of the can lids is realized;

[0023] Among them: A support seat 8 is fixedly connected to the middle of the stamping frame 1. Uniformly distributed grooves 9 are arranged inside the support seat 8;

[0024] Among them: A conveyor table 10 is fixedly connected to the lower end of the stamping frame 1. A conveyor table 12 is arranged on the front side of the stamping frame 1. The front end of the conveyor table 10 is cooperatively installed with the left end of the conveyor table 12. An electric conveyor belt 11 is arranged inside the conveyor table 10. An electric conveyor belt 13 is arranged inside the conveyor table 12. The input ends of the electric conveyor belt 11 and the electric conveyor belt 13 are both electrically connected to the output end of the control switch group 14.

[0025] The working principle of a can lid stamping machine provided by the present utility model is as follows: During operation, the operator stably places the stamping frame 1, the second conveyor table 12, and other mechanisms in a horizontal working area. After stable placement, the operator activates the motor 31 through the control switch group 14. The output shaft of the motor 31 rotates to drive the longitudinally adjacent drive shaft 32 to rotate. The rotation of the drive shaft 32 drives the longitudinally adjacent drive gear 33 to rotate. The rotation of the left drive gear 33 drives the right drive gear 33 to rotate, thereby driving both connecting shafts 34 to rotate around the central axis of the longitudinally adjacent drive shaft 32. The rotation of the connecting shafts 34 drives the upper ends of the longitudinally adjacent connecting rods 35 to rotate around the central axis of the longitudinally adjacent drive shaft 32. When the upper ends of the connecting rods 35 rotate downward, the lower ends of both connecting rods 35 push the same driving seat 36 downward, thereby causing the stamping seat 2 to move downward under the guiding action of the sliding column 6, and finally driving the stamping die 4 to move downward. The stamping die 4 and the support seat 8 cooperate to work to achieve the stamping and forming of the can lid. The stamped and formed can lids all fall onto the upper end of the first electric conveyor belt 11 through the vertically corresponding grooves 9. The control switch group 14 activates the operation of the first electric conveyor belt 11 and the second electric conveyor belt 13. The first electric conveyor belt 11 conveys the stamped and formed can lids to the upper end of the second electric conveyor belt 13, and then conveys them to the next working area through the second electric conveyor belt 13. When the upper ends of the connecting rods 35 rotate upward, the lower ends of both connecting rods 35 pull the same driving seat 36 upward, thereby causing the stamping seat 2 to move upward under the guiding action of the sliding column 6, and finally driving the stamping die 4 to move upward. Then, the external moving platform adjusts the position of the raw material plate to perform the stamping and forming of the next batch of can lids. By cycling in this way, the up and down reciprocating movement of the stamping die 4 is realized, and the continuous stamping and forming of the can lid is achieved.

[0026] It should be noted that in the above embodiments, the motor 31 disclosed can be an MISD5.213 servo motor. The control switch group 14 is provided with control buttons corresponding to the motor 31, the first electric conveyor belt 11, and the second electric conveyor belt 13 one by one to control their switches.
