However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0024] Such as Figure 1As shown in FIGS. -5, the utility model provides a precise positioning and cutting device for cartons in carton production, which includes a frame 1 and a cutting mechanism 4. A bottom plate 11 is fixedly installed at the lower end of the frame 1, and a precise positioning mechanism 2 is arranged at the upper end of the bottom plate 11. A fixing mechanism 3 is arranged at one end of the precise positioning mechanism 2. The precise positioning mechanism 2 includes a concave seat 21 and a stepping motor 23. Limit blocks 22 are fixedly installed at the upper end of the bottom plate 11 and near both side edges. A plurality of infrared transmitters 25 are fixedly installed at one end of one group of limit blocks 22, and the distance between every two adjacent infrared transmitters 25 is 10 cm. Moving seats 26 are fixedly installed at the lower end of the concave seat 21 and near both side edges. An infrared receiver 24 is fixedly installed at one end of one group of moving seats 26 and at the middle position. A screw rod 27 is rotatably connected to one inner side wall of the frame 1. A threaded seat 28 is fixedly installed at the other end of one group of moving seats 26. One-way cylinders 29 are fixedly installed through the upper end of the concave seat 21 and near both side edges. The extending ends of the two one-way cylinders 29 are fixedly installed with a limit plate 210. Slide grooves 211 are opened on both inner side walls of the concave seat 21. Guide blocks 212 are slidably installed in the two slide grooves 211. Material openings 12 are penetrated and opened at both ends of the frame 1. The lower part of the cutting mechanism 4 is fixed to the frame 1. One end of the stepping motor 23 is fixed to one end of the frame 1. One end of the screw rod 27 passes through the frame 1 and is fixed to the output end of the stepping motor 23. One ends of the two guide blocks 212 are respectively fixed to both ends of the limit plate 210. Two slide rods 262 are fixedly installed inside the frame 1. Two slide seats 261 are slidably installed on the outer walls of the two slide rods 262. One ends of the four slide seats 261 are respectively fixed to the other ends of the two moving seats 26. The outer wall of the screw rod 27 is in threaded connection with the inside of the threaded seat 28. A plurality of infrared receivers 24 are in signal connection with the stepping motor 23. The two one-way cylinders 29 are both in signal connection with the infrared receiver 24.

[0025] The specific settings and functions of this embodiment will be described in detail below. Set the cutting size to be required, and the corresponding position of the size is located at one of several groups of infrared emitters 25, and start the operation of this infrared emitter 25. Start the operation of the stepping motor 23. The output end of the stepping motor 23 drives the screw 27 to rotate. Under the screw-thread fit between the screw 27 and the threaded seat 28, the threaded seat 28 will move on the screw 27. At the same time, the threaded seat 28 drives the moving seat 26 fixed thereto to move. And this moving seat 26 drives another group of moving seats 26 to move on the bottom plate 11 through the concave seat 21, and at the same time drives the infrared receiver 24 fixed thereto to move together. When the infrared receiver 24 moves to the infrared emitter 25 where it is operating, the infrared receiver 24 will receive the signal and control the stepping motor 23 to stop running. At the same time, control the operation of two groups of first cylinders 29. The two groups of first cylinders 29 push the limiting plate 210 to move downward, so that the bottom end of the limiting plate 210 contacts the upper end of the bottom plate 11, thereby enabling the adjustment of the position of the cutting size to be required, accurately positioning the size of the carton, thus reducing the duration of carton size adjustment, not only improving the cutting efficiency of the carton, but also increasing the economic benefits. When the two groups of moving seats 26 move, they will both drive the two groups of sliding seats 261 fixed thereto, so that the four groups of sliding seats 261 slide on the two groups of sliding rods 262 respectively, increasing the stability of the movement of the two groups of moving seats 26. When the limiting plate 210 moves downward, the limiting plate 210 will drive the two groups of guiding blocks 212 fixed thereto to move, so that the two groups of guiding blocks 212 slide downward inside the two groups of sliding grooves 211 respectively, thereby increasing the stability of the downward movement of the limiting plate 210. Embodiment

[0026] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5 shown, the fixing mechanism 3 includes two groups of pressing plates 31 and two groups of second cylinders 32. Connecting frames 33 are fixedly installed at the extending ends of the two groups of second cylinders 32. Elliptical plates 34 are arranged above the two groups of pressing plates 31. Three vertical rods 36 are fixedly installed at the lower ends of the two groups of elliptical plates 34. Guide sliders 35 are slidably installed on the outer walls of the six vertical rods 36. Three vertical grooves 37 are opened at the other ends of the two groups of limiting blocks 22. The lower ends of the two groups of connecting frames 33 are respectively fixed to the upper ends of the two groups of pressing plates 31. The upper ends of the two groups of second cylinders 32 are respectively fixed to the lower ends of the two groups of guiding blocks 212. The lower ends of the six vertical rods 36 respectively pass through the six vertical grooves 37 and are fixed to the upper end of the bottom plate 11. One ends of the six guide sliders 35 are respectively fixed to one ends of the two groups of pressing plates 31.

[0027] The effect achieved by the entire embodiment is as follows: Start two sets of second cylinders 32. The two sets of second cylinders 32 respectively drive the connecting frames 33 fixed thereto to move downward. Both sets of connecting frames 33 will drive the pressing plates 31 fixed thereto to move downward, so that the two pressing plates 31 limit the cartons on the bottom plate 11, thereby being able to fix the cartons and facilitating the cutting mechanism 4 to cut the cartons. At the same time, when the two pressing plates 31 move downward, the two pressing plates 31 respectively drive the three guide sliders 35 fixed thereto to move, so that the six guide sliders 35 slide downward on the six vertical rods 36 respectively, thereby playing a guiding role and facilitating the six guide sliders 35 to accurately move into the six vertical grooves 37, increasing the stability when the six guide sliders 35 move downward.

[0028] The usage method and working principle of this device are as follows: First, according to the size of the carton to be cut, start the infrared emitter 25 of the corresponding size to operate, and start the stepping motor 23 to operate. The output end of the stepping motor 23 drives the screw rod 27 to rotate. Under the screw thread cooperation of the screw rod 27 and the thread seat 28, the thread seat 28 will move on the screw rod 27. At the same time, the thread seat 28 drives the moving seat 26 fixed thereto to move. And this moving seat 26 drives another set of moving seat 26 to move on the bottom plate 11 through the concave seat 21, and at the same time drives the infrared receiver 24 fixed thereto to move together. When the infrared receiver 24 moves to the position of the operating infrared emitter 25, the infrared receiver 24 will receive the signal and control the stepping motor 23 to stop operating. At the same time, control the two sets of first cylinders 29 to operate. The two sets of first cylinders 29 push the limiting plate 210 downward to make the bottom end of the limiting plate 210 contact with the upper end of the bottom plate 11, so as to adjust the position of the size to be cut, be able to accurately position the size of the carton, thereby reducing the time for adjusting the carton size. Then, pass the carton through one of the material openings 12 and push the carton to make it contact with one end of the limiting plate 210. Finally, start the two sets of second cylinders 32. The two sets of second cylinders 32 respectively drive the connecting frames 33 fixed thereto to move downward. Both sets of connecting frames 33 will drive the pressing plates 31 fixed thereto to move downward, so that the two pressing plates 31 limit the cartons on the bottom plate 11, and then control the cutting mechanism 4 to operate to cut the carton fixed on the bottom plate 11.
