Detailed Description of the Preferred Embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-4 shown, a punching machine for sheet-like objects includes a punching rack 1. A driving cylinder 2 is installed at the rear position of the top end of the punching rack 1 through a support frame. The bottom end of the driving shaft of the driving cylinder 2 is connected with a punching template 3. A feeding assembly 4 is arranged inside the punching rack 1;

[0024] The feeding component 4 includes a conveying chain belt 5. The conveying chain belt 5 is installed at the upper position inside the stamping frame 1 through a driving gear roller. A number of mounting frames 6 are arranged on the outer ring of the conveying chain belt 5. Two mounting frames 6 in the same straight line form a group. At the top ends of the two mounting frames 6 in the same group, support platforms 8 are fixedly installed. On the top end of the support platform 8, there is a sheet body 9, and the punching template 3 matches the sheet body 9. At the rear position of the top end of the stamping frame 1, a feeding motor is installed, and the driving shaft of the feeding motor is connected to the driving gear roller of the conveying chain belt 5. At the lower position inside the stamping frame 1, there is a debris collection box 14, and universal casters are arranged at the bottom end of the debris collection box 14. The support platform 8 does not contact the debris collection box 14.

[0025] In this embodiment, mounting bolts 7 are arranged at the upper and lower ends of the mounting frame 6 near both sides, and the mounting frame 6 is detachably connected to the conveying chain belt 5 through the mounting bolts 7, which is convenient for disassembling and replacing the mounting frame 6.

[0026] In this embodiment, at one end of each of the two support platforms 8 away from the sheet body 9, a limiting block 10 is fixedly connected. Inside the stamping frame 1 and below the punching template 3, a support plate 11 that matches the limiting block 10 is fixedly connected. The gap between the top surface of the support plate 11 and the bottom surface of the limiting block 10 is not less than 0.5 mm and not more than 1 mm. Through the support plate 11, the limiting block 10 is supported, so that the punching force does not directly act on the conveying chain belt 5, which is convenient for reducing the probability of the conveying chain belt 5 being damaged and improving the stamping stability at the same time.

[0027] In this embodiment, an electric telescopic rod 13 is installed inside the stamping frame 1 and near the rear end of the support plate 11, and a baffle 12 is installed at the top end of the push rod of the electric telescopic rod 13. When the rear end of the limiting block 10 touches the front end of the baffle 12, the punching template 3 and the sheet body 9 are in the same vertical line. By setting the baffle 12, the limiting block 10 is blocked, which is convenient for positioning during stamping.

[0028] In this embodiment, a discharging frame 15 is arranged at the rear end of the stamping frame 1. Inside the discharging frame 15, a discharging conveyor belt 16 is rotatably installed through two first rollers. At the rear positions on both sides of the discharging frame 15, electric telescopic rods 17 are movably installed through mounting seats. The ends of the push rods of the two electric telescopic rods 17 are connected to both sides of the first roller at the rear of the discharging conveyor belt 16, and movable grooves that match the first roller are opened on both sides of the discharging frame 15. By means of the telescopic movement of the push rods of the electric telescopic rods 17, the angle of the discharging conveyor belt 16 can be adjusted conveniently.

[0029] In this embodiment, a feeding rack is fixedly connected to the rear end of the discharging rack 15. Inside the feeding rack, a plurality of feeding conveyor belts 18 are rotatably installed through a plurality of second rollers. The plurality of feeding conveyor belts 18 are arranged at equal intervals in the feeding rack. The top surface of the discharging conveyor belt 16 is on the same horizontal plane as the top surface of one of the feeding conveyor belts 18 at the uppermost position. A plurality of feeding conveyor belts 18 are arranged vertically behind the discharging conveyor belt 16. By adjusting the angle of the discharging conveyor belt 16, the stamped sheet body 9 can be conveyed onto different feeding conveyor belts 18, so as to be conveyed to different workstations, enabling the personnel at the remaining workstations not to walk to a single discharging port to pick up the sheet body 9, which is convenient for reducing the labor intensity of the personnel.

[0030] In this embodiment, a discharging motor and a feeding motor are respectively installed on one side of the discharging rack 15 and the feeding rack. The driving shaft of the discharging motor is in transmission connection with the first roller away from the second electric telescopic rod 17. The driving shaft of the feeding motor is in transmission connection with a plurality of second rollers through a transmission pulley group. By providing the discharging motor and the feeding motor, it is convenient to drive the discharging conveyor belt 16 and the feeding conveyor belt 18 to rotate, facilitating the conveying of materials.

[0031] It should be noted that the present utility model is a punching machine applicable to sheet-like objects. When in use, first, the sheet body 9 to be punched can be placed on the support table 8 as needed. Since the conveying chain belt 5 is rotatably installed in the punching rack 1 and the support table 8 is installed on the conveying chain belt 5 through the mounting rack 6, after placing, the feeding motor can be started. The feeding motor drives the conveying chain belt 5 to rotate. During the rotation of the conveying chain belt 5, the support table 8 can be driven to move, thereby driving the sheet body 9 to move towards the driving cylinder 2 until the limiting block 10 touches the baffle 12, at which time the conveying chain belt 5 stops rotating, and the push rod of the driving cylinder 2 is controlled to extend to drive the punching template 3 to punch the sheet body 9.

[0032] At the same time, since the bottom end of the baffle 12 is connected to the push rod of the first electric telescopic rod 13, after punching, the push rod of the first electric telescopic rod 13 can be controlled to retract to drive the baffle 12 to move downward, thereby removing the block on the limiting block 10. Then, the conveying chain belt 5 can be controlled to rotate again, so that the sheet body 9 on the support table 8 after stamping is conveyed onto the discharging conveyor belt 16.

[0033] During conveying, since there are a plurality of support tables 8, after the previous support table 8 moves away, the push rod of the first electric telescopic rod 13 is controlled to extend again to block the next support table 8. At the same time, as the conveying chain belt 5 drives the support table 8 to move, when the support table 8 returns to its original position after conveying the stamped sheet body 9 to the discharging conveyor belt 16, the sheet body 9 can be placed on the support table 8 again until all the sheet bodies 9 are processed.

[0034] Moreover, during the process, there is no need to wait for the stamping to be completed before picking and placing, which is convenient for saving the waiting time of feeding and improving the processing efficiency. At the same time, the human hand will not directly reach under the punching template 3 to pick up, reducing the probability of accidental injury.

[0035] Moreover, the rear roller one of the discharging conveyor belt 16 is installed on the discharging rack 15 through the electric telescopic rod two 17. The discharging conveyor belt 16 is rotationally connected with the push rod of the electric telescopic rod two 17. The electric telescopic rod two 17 is also movably connected with the discharging rack 15 through the mounting seat. Thus, the angle of the discharging conveyor belt 16 can be adjusted by the telescopic movement of the push rod of the electric telescopic rod two 17. Since a plurality of feeding conveyor belts 18 are arranged in the upper and lower rows behind the discharging conveyor belt 16, the stamped sheet body 9 can be conveyed onto different feeding conveyor belts 18, so as to be conveyed to different workstations, enabling the personnel at the remaining workstations not to walk to a single discharging port to pick up the sheet body 9, which is convenient for reducing the labor intensity of the personnel.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
