[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] like Figure 1-Figure 4 As shown, the utility model provides a copy paper cutting device for a copy machine, including a copy machine body 1, a side wall of the copy machine body 1 is fixedly connected to a placing table 2, the side wall of the copy machine body 1 is provided with a cutting structure 3, and the lower surface of the rectangular tube 305 is provided with a limiting structure 4.

[0030] The specific settings and functions of the cutting structure 3 and the limiting structure 4 are described in detail below.

[0031] like Figure 2 and Figure 3 As shown, the cutting structure 3 includes a support plate 301, the support plate 301 is fixedly connected to the photocopier body 1, a rotating rod 302 is rotatably connected inside the support plate 301, the lower end of the rotating rod 302 is fixedly connected to a connecting plate 303, a first electric push rod 304 is fixedly connected to the surface of the connecting plate 303, an output end of the first electric push rod 304 is fixedly connected to a rectangular tube 305, an inner wall of the rectangular tube 305 is slidably connected to two tool holders 306, an inner wall of the tool holder 306 is detachably mounted with a cutting knife 307, a second electric push rod 308 is fixedly connected to the upper surface of the support plate 301, an output end of the second electric push rod 308 is fixedly connected to The rack 309 and the upper end of the rotating rod 302 are fixedly connected with a gear 310, and the gear 310 is meshed with the rack 309. The rectangular tube 305 is internally threaded with a bolt 312, and the bolt 312 passes through the rectangular tube 305 and abuts against the surface of the tool holder 306. The bolt 312 is rotated, and after the bolt 312 abuts against the surface of the tool holder 306, the position of the tool holder 306 can be fixed, thereby fixing the position of the cutting knife 307. A positioning rod 311 is slidably connected in the connecting plate 303, and the positioning rod 311 is fixedly connected to the rectangular tube 305. The positioning rod 311 can ensure that the rectangular tube 305 rotates synchronously with the connecting plate 303.

[0032] like Figure 2 and Figure 4 As shown, the limiting structure 4 includes a circular tube 41, which is fixedly connected to the rectangular tube 305. A circular rod 42 is slidably connected to the inner wall of the circular tube 41. The lower end of the circular rod 42 is fixedly connected to a limiting plate 43. The upper end of the circular rod 42 is fixedly connected to a spring 44. The upper end of the spring 44 is fixedly connected to the rectangular tube 305. The spring 44 can increase the pressure of the limiting plate 43 on the photocopy paper, thereby improving the limiting effect of the limiting plate 43. A plurality of through holes 45 are provided on the surface of the limiting plate 43. The through holes 45 can prevent the photocopy paper located above from moving when the limiting plate 43 moves upward.

[0033] The overall working principle is that when the photocopy paper needs to be cut, the stacked photocopy paper is placed on the placing table 2, and then the output end of the first electric push rod 304 is controlled to extend, the rectangular tube 305 will move downward, the movement of the rectangular tube 305 will drive the round tube 41 to move, the movement of the round tube 41 will move the round rod 42, and the movement of the round rod 42 will drive the limit plate 43 to move and press on the surface of the photocopy paper. As the rectangular tube 305 continues to move downward, the spring 44 will be compressed, so the round rod 42 will move with the help of the spring 44. The elastic force causes the limit plate 43 to press the photocopy paper tightly to prevent the photocopy paper from sliding during the cutting process and affecting the cutting effect. The knife holder 306 moves with the help of the rectangular tube 305 to drive the cutting knife 307 to move. After the cutting knife 307 contacts the photocopy paper, it will cut the photocopy paper. After the cutting is completed, the output end of the first electric push rod 304 is controlled to shrink. At this time, the through hole 45 can prevent the limit plate 43 from moving upward and driving the photocopy paper located above to move. When the limit plate 43 is out of contact with the photocopy paper, the second electric push rod is controlled to shrink. The output end of the rod 308 extends, the rack 309 drives the gear 310 to rotate, the gear 310 drives the rotating rod 302 to rotate, the rotating rod 302 drives the positioning rod 311 to rotate, the positioning rod 311 drives the rectangular tube 305 to rotate, and finally drives the cutting knife 307 to rotate ninety degrees. In this process, the positioning rod 311 can ensure that the rectangular tube 305 rotates synchronously with the connecting plate 303, and then the output end of the first electric push rod 304 is controlled to extend again to cut the other two sides of the photocopy paper. In this process, , the user does not need to frequently move the copy paper and press the copy paper, and the cutting efficiency is high. When it is necessary to cut copy paper of different sizes, the knife holder 306 is slid along the inner wall of the rectangular tube 305. The sliding of the two knife holders 306 will adjust the distance between the two cutting knives 307, so that copy paper of different sizes can be cut. After the adjustment is completed, the bolt 312 is rotated. After the bolt 312 is against the surface of the knife holder 306, the position of the knife holder 306 can be fixed, thereby fixing the position of the cutting knives 307.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
