[0002] The die-cutting machine is a device specially used for post-printing processing of paper. The paper feeding mechanism is an important component of the die-cutting machine. The traditional paper feeding mechanism mainly includes a lifting platform, which is connected to a drive chain. The tray with stacked papers is sent to the lifting platform, and then the drive chain is controlled to move to drive the lifting platform and the tray to the required height for paper feeding. The defect of this structure is that after the tray is placed on the lifting platform, its left and right position is difficult to adjust. In actual use, it is impossible to ensure that the paper is stacked in the middle of the tray, and it is also impossible to ensure that the tray is sent to the lifting platform in the right left and right position. Therefore, it is necessary to set a paper adjustment mechanism to adjust the left and right position of the paper, which makes the structure of the equipment complicated and affects the paper conveying efficiency.

The characteristic is that a movable movable plate is arranged on the lifting frame, a rear positioning plate is arranged at an upper position on one side of the movable plate, the rear positioning plate is connected to a horizontal driving component, a transmission frame is connected to the movable plate, a transmission groove is provided on the transmission frame, an adjusting rod is arranged in the transmission groove, the adjusting rod is arranged on a swing frame, and the swing frame is hinged on the frame.

[0006] Rollers are arranged on the lifting frame, and a reinforcing plate resting on the rollers is arranged on the movable plate.

[0007] The frame is provided with a mounting rod, and a first mounting seat and a second mounting seat are movably provided on the mounting rod. The first mounting seat is provided with a first sensor that can sense the left side of the paper pile, and the second mounting seat is provided with a second sensor that can sense the right side of the paper pile. The frame also includes an adjustment cam connected to the output end of the drive motor, and one end of the swing frame is connected to a spring so that the swing frame is pressed tightly against the adjustment cam. The first and second sensors can transmit information to the controller, and the controller can control the action of the drive motor.

[0008] The bottom of the movable plate is provided with left and right guide wheels, and the two guide wheels are respectively against the two sides of one of the frame plates of the lifting frame.

[0009] The adjustable die-cutter paper feeding mechanism of the above technical solution can place the tray on the movable plate by additionally setting a movable plate on the lifting frame. The movable plate can be controlled to move left and right, and then the left and right position of the paper pile can be adjusted, so that the paper pile can be accurately delivered to the paper feeding station. There is no need to set up subsequent left and right adjustment mechanisms, which makes the structure of the equipment simpler and improves the paper conveying efficiency.

[0015] As shown in the figure, the adjustable die-cutting machine paper feeding mechanism disclosed by the utility model includes a lifting frame 2, the lifting frame 2 is connected to the driving chain, the driving chain is passed around the driving sprocket, the driving sprocket is connected to the driving motor by transmission, a movable moving plate 1 is arranged on the lifting frame 2, a rear positioning plate 6 is arranged at the upper position of one side of the moving plate 1, the rear positioning plate 6 is connected to the horizontal driving component, the moving plate 1 is connected to the transmission frame 3, the transmission frame 3 is provided with a transmission groove 4, the transmission groove 4 is provided with an adjustment rod 5, the adjustment rod 5 is arranged on the swing frame 7, and the swing frame 7 is hinged on the frame. Furthermore, rollers 12 are arranged on the lifting frame 2, and a reinforcing plate 13 is arranged on the moving plate 1 to abut against the rollers 12, so that the movement of the moving plate 1 is smoother and more reliable. In addition, in order to realize automatic detection and adjustment, a mounting rod 17 is provided on the frame, and a first mounting seat and a second mounting seat are movably provided on the mounting rod 17. A first sensor 16 that can sense the left side of the paper pile is provided on the first mounting seat, and a second sensor 15 that can sense the right side of the paper pile is provided on the second mounting seat. It also includes an adjustment cam 9 connected to the output end of the drive motor, and a spring 8 is connected to one end of the swing frame 7, so that the swing frame 7 is pressed tightly against the adjustment cam 9. The first and second sensors can transmit information to the controller, and the controller can control the action of the drive motor by controlling the first and second mounting seats to move to appropriate positions. When the first and second sensors both detect the side of the paper, it means that the left and right positions of the paper are in place at this time. If one sensor does not detect the paper, it means that the left and right positions of the paper need to be adjusted. At this time, the controller will control the drive motor to drive the drive shaft 10 and the adjustment cam 9 to rotate, thereby driving the swing frame 7 to swing, driving the adjustment rod 5 to move, and then driving the transmission frame 3 and the movable plate 1 to move, and adjusting the left and right positions of the paper until both sensors can sense the side of the paper. Furthermore, the bottom of the movable plate 1 has left and right guide wheels 14 , and the two guide wheels 14 respectively abut against two sides of one of the plates of the lifting frame 2 to guide the movement of the movable plate 1 .

[0016] The working principle of the utility model is: a tray with a pile of papers is sent to the movable plate 1, and one side is against the rear positioning plate 6 to realize its rear positioning. If there is an offset in the left and right positions of the papers, the swing frame 7 is controlled to swing, the dynamic adjustment rod 5 is actuated, and then the transmission frame 3 and the movable plate 1 are driven to move, and the left and right positions of the papers are adjusted. The swing of the swing frame 7 can be manually controlled, or it can be automatically adjusted by the above-mentioned sensor and the adjustment cam 9.

[0017] The structure of the utility model can place the tray on the movable plate by additionally arranging a movable plate on the lifting frame, and can control the movable plate to move left and right, thereby adjusting the left and right position of the paper pile, so that the paper pile can be accurately delivered to the paper feeding station, and there is no need to arrange a subsequent left and right adjustment mechanism, which makes the structure of the equipment simpler and improves the paper conveying efficiency.
