[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] According to an embodiment of the present utility model, a carton continuous die-cutting device is provided, including a die-cutting belt conveyor 1, a die-cutting fixing component 2 is installed above the die-cutting belt conveyor 1, a die-cutting installation component 3 is provided on one side of the die-cutting fixing component 2, and a cardboard collection and protection component 4 is provided on one side of the die-cutting belt conveyor 1.

[0026] like Figure 1-4As shown, according to the embodiment of the present invention, the carton continuous die-cutting device includes a die-cutting fixed component 2 including a fixed mounting frame 201, the fixed mounting frame 201 is fixedly installed above the die-cutting belt conveyor 1, and a fixed threaded rod 202 is symmetrically and movably installed inside the fixed mounting frame 201, one end of the fixed threaded rod 202 is connected to a drive motor 203, the drive motor 203 shell is connected to the fixed mounting frame 201, the outer periphery of the fixed threaded rod 202 is threadedly connected to a square hollow fixed frame 204, and a trigger mounting groove 205 is opened inside the square hollow fixed frame 204. A thrust spring 206 is installed inside 205, a sliding block 207 is installed at one end of the thrust spring 206, a trigger switch 208 is installed on one side of the sliding block 207, a sliding groove 209 is opened inside the square hollow fixed frame 204, a sliding rod 210 is slidably matched inside the sliding groove 209, the sliding rod 210 is connected to the fixed mounting frame 201, a PLC controller 211 is installed on one side of the die-cutting belt conveyor 1, the trigger switch 208 and the drive motor 203 are electrically connected to the PLC controller 211 respectively, and a buffer rubber layer 5 is provided on one side of the square hollow fixed frame 204.

[0027] Through the above technical solution, the cardboard is moved to the bottom of the die-cutting installation assembly 3 by the die-cutting belt conveyor 1, and then the driving motor 203 drives the fixed threaded rod 202 to rotate in the fixed installation frame 201. When the fixed threaded rod 202 rotates, it can drive the square hollow fixing frame 204 to move, and the square hollow fixing frame 204 can clamp the cardboard. After that, when the cardboard is clamped, the cardboard drives the trigger switch 208 to move. When the trigger switch 208 moves, it can drive the sliding block 207 to move in the trigger installation groove 205. At the same time, under the thrust of the thrust spring 206 and the contact with the cardboard, the trigger switch 208 can be triggered by the extrusion force. At this time, the trigger switch 208 stops the driving motor 203 through the PLC controller 211, thereby achieving the effect of automatic stopping of clamping, so that the buffer rubber layer 5 can prevent the cardboard from being damaged.

[0028] like Figure 1-4 As shown, according to the carton continuous die-cutting device of an embodiment of the present utility model, the die-cutting installation component 3 includes a die-cutting installation frame 301, the die-cutting installation frame 301 is connected to the die-cutting belt conveyor 1, and the die-cutting electric push rod 302 is symmetrically installed inside the die-cutting installation frame 301. The output end of the die-cutting electric push rod 302 is connected to the cross-cutting installation plate 303, and the die-cutting knife 304 is installed at the bottom of the cross-cutting installation plate 303. The die-cutting electric push rod 302 is electrically connected to the PLC controller 211.

[0029] Through the above technical solution, by setting the die-cutting mounting frame 301, it is convenient to fix the die-cutting electric push rod 302. After the die-cutting electric push rod 302 is started, it can drive the cross-cutting mounting plate 303 to move. When the cross-cutting mounting plate 303 moves, it can drive the die-cutting knife 304 to move. When the die-cutting knife 304 moves, it can die-cut the cardboard.

[0030] The die-cutting belt conveyor 1 uses a cut-resistant belt.

[0031] like Figure 1-4 As shown, according to the carton continuous die-cutting device of the embodiment of the utility model, the cardboard collection and protection component 4 includes a cardboard collection box 401, an anti-collision layer 402 is installed on the inner wall of the cardboard collection box 401, a sponge pad 403 is installed inside the cardboard collection box 401, and a cardboard removal slot 6 is opened on one side of the cardboard collection box 401.

[0032] Through the above technical solution, by providing the cardboard collection box 401, it is convenient to collect cardboards, the anti-collision layer 402 and the sponge pad 403 can prevent cardboards from being damaged, and by providing the cardboard removal slot 6, it is convenient to remove cardboards.

[0033] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0034] The cardboard is moved to the bottom of the die-cutting installation assembly 3 by the die-cutting belt conveyor 1, and then the driving motor 203 drives the fixed threaded rod 202 to rotate in the fixed installation frame 201. When the fixed threaded rod 202 rotates, it can drive the square hollow fixing frame 204 to move, and the square hollow fixing frame 204 can clamp the cardboard. After that, when the cardboard is clamped, the cardboard drives the trigger switch 208 to move. When the trigger switch 208 moves, it can drive the sliding block 207 to move in the trigger installation groove 205. At the same time, the trigger switch 208 contacts the cardboard under the thrust of the thrust spring 206, so that the trigger switch 208 is triggered by the squeezing force. At this time, the trigger switch 208 stops the driving motor 203 through the PLC controller 211, thereby achieving the effect of automatically stopping the clamping, so that the buffer rubber layer 5 can prevent the cardboard from being damaged.

[0035] By providing the die-cutting mounting frame 301, the die-cutting electric push rod 302 is fixed. When the die-cutting electric push rod 302 is started, it can drive the cross-cutting mounting plate 303 to move. When the cross-cutting mounting plate 303 moves, it can drive the die-cutting knife 304 to move. When the die-cutting knife 304 moves, it can die-cut the cardboard.

[0036] By providing the cardboard collection box 401, it is convenient to collect cardboards, the anti-collision layer 402 and the sponge pad 403 can prevent cardboards from being damaged, and by providing the cardboard removal slot 6, it is convenient to remove cardboards.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
