[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1 - Figure 3 As shown, a moisture-proof and environmentally friendly carton production die-cutting device includes: a die-cutting frame 1, wherein the die-cutting frame 1 is provided with a die-cutting upper plate 2 and a die-cutting lower plate assembly 3;

[0028] The die-cutting lower plate assembly 3 is fixedly connected to a supporting plate 301 on one side close to the die-cutting upper plate 2, and extrusion bars 302 are vertically slidably installed on both sides of the supporting plate 301, and two pushing cottons 304 are slidably installed on the supporting plate 301 corresponding to the middle position of the two extrusion bars 302, and a limiting rod 303 is slidably installed on the supporting plate 301 corresponding to the middle position of the two pushing cottons 304, and a limiting assembly 310 is provided at the end of the limiting rod 303, and a sliding friction groove is opened at the position of the supporting plate 301 corresponding to the limiting assembly 310, and the limiting assembly 310 is slidably installed with the sliding friction groove, and an elastic return rope is provided between the extrusion bar 302 and the pushing cotton 304.

[0029] Each time the cardboard is cut into film, the die-cutting upper plate 2 and the die-cutting lower plate assembly 3 are buckled and die-cut once. When the film is cut, the extrusion bar 302 is pressed into the inside of the carrier plate 301 by squeezing. At this time, the extrusion bar 302 pulls the pushing cotton 304 on both sides to move to the middle position through the components set inside the carrier plate 301. If a cardboard is placed, it will also be pushed to a position until it contacts the limit rod 303 and stops. Then the film is cut. After the film cutting is completed, the die-cutting upper plate 2 and the die-cutting lower plate assembly 3 are separated. The extrusion bar 302 is reset and the cotton 304 is reset under the action of the elastic return rope.

[0030] Each time the cutting die is replaced, the position of the limiting rod 303 needs to be adjusted once through the limiting assembly 310 to adapt it to the position of the cutting die.

[0031] Refer to the attached Figure 3 - Figure 6, a distance increasing wheel 307 is provided inside the supporting plate 301 on the side corresponding to the extrusion strip 302, and the distance increasing wheel 307 is divided into an upper and lower part and a driving small wheel 3071 and a driving large wheel 3072. The diameter of the driving small wheel 3071 is smaller than the diameter of the driving large wheel 3072. The driving small wheel 3071 and the driving large wheel 3072 are fixedly connected and a placement cavity is provided inside. A reset spring is provided in the placement cavity, and the two ends of the reset spring are respectively fixedly connected to the supporting plate 301 and the inner wall of the placement cavity. There are multiple distance increasing wheels 307, and the multiple distance increasing wheels 307 are arranged in a vertical array. A transmission rope 308 is wound on a driving small wheel 3071 at one end of the multiple distance increasing wheels 307, and the other end A traction elastic rope 309 is wound on a driving large wheel 3072, wherein the end of the transmission rope 308 is fixedly connected to the extrusion bar 302 on the side close to itself, wherein the end of the traction elastic rope 309 is fixedly connected to the pushing cotton 304 on the side away from itself, and a pulley 306 is provided between the distance increasing wheel 307 and the extrusion bar 302, and the traction elastic rope 309 is transmission-connected to the pulley 306; a connecting rope 305 is wound on the driving large wheel 3072 fixed at the bottom of the driving small wheel 3071 on which the transmission rope 308 is wound, and the connecting rope 305 extends to the distance increasing wheel 307 and the adjacent distance increasing wheel 307, and is wound on the outside of the driving small wheel 3071 of the distance increasing wheel 307.

[0032] According to the above structure, as the extrusion bar 302 slides down, the extrusion bar 302 pulls the driving wheel 3071 to rotate through the transmission rope 308. At this time, the driving wheel 3071 drives the driving wheel 3072 to rotate. Since the driving wheel 3072 is wound with a connecting rope 305, the second distance-increasing wheel 307 is driven to rotate through the connecting rope 305. Due to the difference in diameter between the driving wheel 3071 and the driving wheel 3072, the backward rotation distance becomes larger and larger, and finally the force is transmitted to the pushing cotton 304 on the side away from itself through the traction elastic rope 309. The pushing cottons 304 on both sides approach each other. If a cardboard is put in, the pushing cotton 304 pushes the cardboard to move to the position between the two limit rods 303. At this time, the pushing cotton 304 is blocked by the limit rod 303 and cannot move. The remaining tension of the traction elastic rope 309 will act on itself, causing itself to be stretched.

[0033] Refer to the attached Figure 7 - Figure 8The limit assembly 310 includes a limit handle 311, a friction limit block 313 is vertically slidably installed inside the limit handle 311, the friction limit block 313 contacts the sliding friction groove and the contact surface is set to a rough surface, a grip rod 312 is horizontally slidably installed inside the limit handle 311, and the limit handle 311 is rotatably connected to the pulling roller 314 corresponding to the position inside the friction limit block 313, and the two ends of the pulling roller 314 are fixedly connected to the power wheel 316, and the power wheel 316 is wound on the limit traction rope 317, and the limit traction rope 317 extends to the outside of the limit handle 311 and is fixedly connected to the grip rod 312, a pulling rope is fixedly connected between the pulling roller 314 and the friction limit block 313, and a limit spring 315 is also fixedly connected between the two ends of one side of the friction limit block 313 and the limit handle 311.

[0034] According to the above structure, it is necessary to adjust the position of the limit rod 303 through the limit assembly 310, and move the limit rod 303 to both sides of the corresponding position of the cutting die according to the position of the cutting die. When the position of the limit rod 303 needs to be adjusted, hold the grip rod 312 tightly, and pull the power wheel 316 through the grip rod 312 to rotate. At this time, rotate the pulling roller 314 to make the pulling rope pull the friction limit block 313 to move. At this time, the limit spring 315 is compressed. It is only necessary to separate the friction limit block 313 from the sliding friction groove to move the limit rod 303. When the limit rod 303 moves to the predetermined position, release the grip rod 312. Under the action of the limit spring 315, the friction limit block 313 is reset. At this time, the friction limit block 313 is reset by pulling the pulling roller 314 by the pulling rope.

[0035] The working principle of the present invention is as follows: each time a cardboard is cut into film, the die-cutting upper plate 2 and the die-cutting lower plate assembly 3 are engaged and die-cut once. When the film is cut into film, the extrusion bar 302 is pressed into the interior of the carrier plate 301 by squeezing. At this time, the extrusion bar 302 pulls the pushing cotton 304 on both sides to the middle position through the components set inside the carrier plate 301. If a cardboard is placed in it, it will also be pushed into the position until it contacts the limit rod 303 and stops, and then the cardboard is cut into film.

[0036] Each time the cutting die is replaced, the position of the limit rod 303 needs to be adjusted once through the limit assembly 310, and the limit rod 303 is moved to the position on both sides of the cutting die. When the pushing cotton 304 contacts it, it can stop under the action of resistance, so that the cardboard is exactly located at the position corresponding to the cutting die.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
