[0026] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0027] As Figures 1-5 shown, an automatic paper barrel punching device includes:

[0028] Mounting frame 2;

[0029] Vertical moving mechanism; the vertical moving mechanism is installed on the mounting frame 2; the lower end of the vertical moving mechanism is connected to the top of a U-shaped connecting frame, and the open end of the U-shaped connecting frame faces downward;

[0030] Two groups of punching mechanisms 4; the two groups of punching mechanisms 4 are respectively installed on the inner sides of the two ends of the U-shaped connecting frame and are arranged oppositely, and the operating directions of the two groups of punching mechanisms 4 are both in the horizontal direction;

[0031] Conveyor belt 1 for conveying the paper barrel 14; the conveyor belt 1 horizontally passes through the mounting frame 2;

[0032] In-place sensor for detecting whether the paper barrel 14 is conveyed to the working position; the in-place sensor is installed on the bracket of the conveyor belt 1 and is placed below the U-shaped connecting frame. When the paper barrel 14 reaches the working position, it is placed between the two groups of punching mechanisms 4.

[0033] As Figures 2-4As shown in the figure, the vertical movement mechanism includes a first cylinder 3. The U-shaped connecting frame includes a cross plate 6 and two vertical plates 8. The piston rod of the first cylinder 3 is connected to the cross plate 6. The upper ends of the two vertical plates 8 are respectively connected to both ends of the cross plate 6. The punching mechanism 4 includes a second cylinder 41 and a punching head 42. The punching head 42 includes a first clamping plate 421 and two punching pins 422. The bottom of the second cylinder 41 is installed inside the vertical plate 8. The piston rod of the second cylinder 41 is connected to the first side of the first clamping plate 421. The two punching pins 422 are installed on the second side of the first clamping plate 421. The two punching pins 422 are arranged in parallel and are on the same horizontal plane. There are also two second clamping plates 7 provided below the cross plate 6. The second clamping plates 7 are provided with two pin holes 71 along the horizontal direction. When the punching pins 422 punch holes in the paper barrel 14, the first clamping plate 421 and the second clamping plates 7 clamp the side wall of the paper barrel 14, and the punching pins 422 are inserted into the pin holes 71.

[0034] As Figure 4 shown in the figure, both the first clamping plate 421 and the second clamping plates 7 are formed into arcs that match the shape of the paper barrel 14. The structures of the first clamping plate 421 and the second clamping plates 7 can fit the inner and outer side walls of the paper barrel 14 to ensure the accurate punching position of the paper barrel 14.

[0035] As Figure 3 shown in the figure, the automatic punching device for the paper barrel 14 further includes two groups of parallel first linear guide rails 5. The first linear guide rails 5 include a first slide rail 51 and a first slider 52. The first slide rail 51 is vertically installed on the mounting frame 2. The two first sliders 52 are respectively connected to both ends of the cross plate 6. The first slide rail 51 and the first slider 52 are in limiting sliding fit. The purpose of setting the first linear guide rails 5 is to keep the movement track of the vertical movement mechanism stable.

[0036] As Figures 2-3 shown in the figure, the automatic punching device for the paper barrel 14 further includes a third cylinder 9 and a stop rod 10. The third cylinder 9 is vertically installed on the mounting frame 2. The piston rod of the third cylinder 9 is connected to the upper end of the stop rod 10. The stop rod 10 is vertically arranged. After the paper barrel 14 reaches the working position, the stop rod 10 is stuck in front of the paper barrel 14.

[0037] As Figure 3 shown in the figure, the automatic punching device for the paper barrel 14 further includes a second linear guide rail 13, a handwheel 11, a screw rod 12, and a nut. The second linear guide rail 13 includes a second slide rail 131 and a second slider 132. The second slide rail 131 is vertically installed on the mounting frame 2. The second slider 132 is connected to the first cylinder 3. The second slide rail 131 and the second slider 132 are in limiting sliding fit. The screw rod 12 is vertically arranged. The screw rod 12 is rotatably connected to the second slide rail 131 through a bearing. The upper end of the screw rod 12 is connected to the handwheel 11. The lower part of the screw rod 12 is in threaded cooperation with the nut. The nut is fixedly connected to the second slider 132.

[0038] When the present application is working, first, by turning the handwheel 11, the lowest working height of the punching mechanism 4 is adjusted. The specific operation is as follows: Turn the handwheel 11, and the handwheel 11 drives the screw 12 to rotate. Since the screw 12 is rotatably connected to the second slide rail 131 through a bearing, the up-and-down position of the screw 12 remains unchanged. And because the screw 12 is in threaded cooperation with the nut, the nut is connected to the second slider 132, and the second slide rail 131 is in limit sliding cooperation with the second slider 132. Therefore, when turning the handwheel 11, the up-and-down position of the second slider 132 is adjusted, which also realizes the vertical position adjustment of the vertical movement mechanism and the punching mechanism 4 connected to the second slider 132. The work of the vertical movement mechanism is realized by the up-and-down actuation of the first cylinder 3, and the work of the punching mechanism 4 is realized by the horizontal actuation of the second cylinder 41;

[0039] When starting to work, the paper barrel 14 is conveyed by the conveyor belt 1. When the paper barrel reaches the working position, the in-place sensor detects the paper barrel 14, then feeds back the information to the PLC. The PLC controls the conveyor belt 1 to stop, and then controls the first cylinder 3 to act downward, driving the punching mechanism 4 and the second clamping plate 7 to move downward, so that the first clamping plate 421 and the second clamping plate 7 are respectively placed on the outer and inner sides of the paper barrel; and at the same time, the PLC controls the third cylinder 9 to act downward, and the third cylinder 9 pushes the stop rod 10 downward to block the front of the paper barrel 14 to prevent it from moving; then the second cylinder 41 pushes the first clamping plate 421 and the punching needle 422 forward until they pass through the side wall of the paper barrel, and the punching needle 422 is inserted into the needle hole 71 on the punched outer wall of the paper barrel. Then each cylinder acts in the reverse direction, and then the conveyor belt 1 continues to convey forward.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
