The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1 This utility model provides a paper output machine length cutting device, which includes a housing 1. The housing 1 has a mounting hole 14 on its rear side, which can be used to fix the device to a wall or bracket. A maintenance door 15 is hinged to the housing 1 below the mounting hole 14, which facilitates maintenance of the internal structure or replacement of parts. A rubber gasket 16 is fixedly connected to the housing 1 below the maintenance door 15, which is used to protect the housing 1 and absorb vibration noise generated during equipment operation. A cover plate 2 is hinged to the upper side of the housing 1, which allows for easy opening and replacement of the roll of paper or cleaning of the interior. The front of the housing 1 is provided with an observation port 11 and a slide 12. The observation port 11 is made of transparent material, which makes it easy for users to observe the paper usage inside. A cutting mechanism 4 is installed in the slide 12 for cutting the paper to the required length. A control board 3 is installed on the housing 1 between the observation port 11 and the slide 12. The control board 3 is provided with a start / stop button and a selection button. The selection button includes three lengths: 8CM, 15CM and 30CM, which users can flexibly select according to their needs. The control board 3 is connected to the stepper motor 7 through a control system with a microprocessor as the core and pulse signals as the command, thereby realizing the automated process from user command to accurate paper output.

[0020] Reference Figure 4The cutting mechanism 4 includes a support plate 41, which is fixedly connected to the bottom of the housing 1 and has a guide groove 42. A slide rod 43 is slidably connected in the guide groove 42. A slider 45 is fixedly connected to one end of the slide rod 43, and a cutting blade 44 is bolted to the other end for easy disassembly and replacement. The slider 45 is located in the slide groove 12 and is slidably connected to the slide groove 12. When the user pushes the slider 45, the cutting blade 44 moves along the guide groove 42 to achieve smooth cutting of the paper.

[0021] Reference Figure 2-3 Inside the housing 1 located below the cover plate 2, a spare box 5 and a mounting bracket 9 are fixedly connected. The mounting bracket 9 is U-shaped and has a paper roll 10 installed inside, which facilitates the installation and replacement of the paper roll. The spare box 5 can be used to store spare paper rolls. A mounting base 6 is fixedly connected to the lower side of the spare box 5. A stepper motor 7 is fixedly connected to the lower end of the mounting base 6. A drive wheel 71 is fixedly connected to the output end of the stepper motor 7. A rubber roller 8 is rotatably connected inside the housing 1 located below the stepper motor 7. There are two rubber rollers 8, and one end of each is fixedly connected to a driven wheel 81. The driven wheels 81 on both sides are meshed together. The drive wheel 71 is meshed with one driven wheel 81. The stepper motor 7 drives the two rubber rollers 8 to rotate in opposite directions through gear transmission, so as to realize the smooth feeding of paper.

[0022] The bottom of the housing 1 is provided with a paper outlet 13. The paper roll on the paper roll 10 passes between the two rubber rollers 8 and is located at the paper outlet 13. After the user selects the desired paper length through the control panel 3, the stepper motor 7 rotates according to the set number of steps, driving the rubber rollers 8 to output the paper of the corresponding length. Then, the user pushes the slider 45, which drives the cutting blade 44 to move along the guide groove 42 to complete the paper cutting.

[0023] Working Principle: During use, the user sets the desired paper length (e.g., 8cm, 15cm, or 30cm) using the selection buttons on the control panel 3. After pressing the start button, the stepper motor 7 receives the control signal and begins to rotate, driving a pair of rubber rollers 8 to rotate in opposite directions via the drive wheel 71 and its meshing driven wheel 81. The paper on the paper roll 10 is held between the two rubber rollers 8 and precisely fed downwards as the rubber rollers 8 rotate, exiting from the paper outlet 13. The stepper motor 7 precisely controls its rotation angle according to the preset length, thereby controlling the length of the paper being delivered.

[0024] Once the paper has been fed to the set length, the stepper motor 7 stops working. At this point, the user manually pushes the slider 45 located in the slide groove 12. The slider 45 drives the slide rod 43 and the cutting blade 44 fixed at its end to slide smoothly along the guide groove 42 on the support plate 41, thereby completing the cutting of the paper. The guide groove 42 ensures the stability and straightness of the cutting process, and the bolt-connected blade also facilitates future replacement.

[0025] When the paper roll runs out, the top cover 2 can be opened to replace the paper roll 10 from the U-shaped mounting bracket 9. The spare box 5 can be used to store spare cutting blades 44 and paper rolls. The maintenance door 15 at the rear of the device facilitates the inspection and maintenance of the internal transmission mechanism.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
