Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The following Figures 1-3 Further detailed description of this application will be made below.

[0024] Referring to Figure 1 And Figure 2 , a flat paper cutter for printing cardboard with accurate positioning, comprising a base 1, two gantries 2 fixedly connected to both sides of the base 1, a cutting cylinder 3 arranged at the top of the gantry 2, two groups of telescopic columns 4 arranged at the bottom of the cutting cylinder 3, sliding seats 5 fixedly connected to the bottom ends of the two groups of telescopic columns 4, a cutting flat knife 6 arranged between the two groups of sliding seats 5, a cutting groove 7 opened on the base 1 and directly below the cutting flat knife 6. The cardboard stack is cut by the cutting flat knife 6, and then the cutting groove 7 can play a role of making way, thereby improving the cutting effect of the bottom layer. Two groups of brackets 11 are fixedly connected to one side of the base 1, a hydraulic telescopic rod 12 is arranged on the bracket 11, the telescopic end of the hydraulic telescopic rod 12 is connected with a positioning plate 13, infrared rangefinders 14 are arranged on both groups of brackets 11, and reflectors 18 are arranged at positions corresponding to the infrared rangefinders 14 on the inner side of the positioning plate 13. The infrared rangefinders 14 emit infrared rays, which are irradiated on the reflectors 18, thereby measuring the current moving distance and achieving accurate positioning, and increasing the cutting effect during operation.

[0025] Referring to Figure 3 , a heightening plate 15 is further arranged on the top of the positioning plate 13, a plurality of connecting columns 19 are arranged on the positioning plate 13, and a plurality of clamping holes adapted to the connecting columns 19 are opened at the bottom of the heightening plate 15. The heightening plate 15 is sleeved above the positioning plate 13, thereby increasing the pushing height and improving the use effect.

[0026] Referring to Figure 2, on one side of the gantry 2, a side frame 8 is provided. On the side frame 8, two sets of electric telescopic rods 9 are provided. The bottom ends of the two sets of electric telescopic rods 9 are fixedly connected with a pressing plate 10. By extending the telescopic ends of the two sets of electric telescopic rods, the pressing plate 10 can press the cardboard stack below, thus facilitating subsequent cutting.

[0027] Refer to Figure 1 , four sets of columns 17 are further provided at the bottom of the base 1. A sliding groove 16 is also formed inside the gantry 2. The sliding seat 5 is slidably connected to the inside of the gantry 2 through the sliding groove 16, which can make the sliding seat 5 more stable during movement, thereby improving the effect of flat knife cutting.

[0028] The implementation principle of this embodiment is as follows: When in use, stack the cardboard to be cut on the base 1, and one side of the cardboard stack contacts the outside of the positioning plate 13 and abuts tightly against the positioning plate 13. Then start the hydraulic telescopic rod 12 to make the positioning plate 13 move, and then push the cardboard stack towards the side of the cutting flat knife 6. During the pushing process, the infrared rangefinder 14 emits infrared rays that are reflected by the reflector, and finally the infrared rangefinder 14 receives the reflection information, thereby accurately positioning the position of the positioning plate 13. When the positioning plate 13 pushes the cardboard stack to the designated position, start the two sets of electric telescopic rods 9 to make the telescopic ends of the two sets of electric telescopic rods 9 extend, and clamp the cardboard stack in position through the pressing plate 10. Then control the cutting flat knife 6 to cut the cardboard stack through the cutting cylinder 3. After cutting is completed, control the pressing plate 10 to loosen, and the cutting flat knife 6 moves to the topmost position, and then the cut cardboard can be removed. When cutting next time, there is no need to perform positioning adjustment again, and directly make one side of the cardboard stack completely abut against one side of the positioning plate 13.
