[0021] Example 1
[0022] According to the present invention, an easily adjustable roll paper cutting device is provided, as shown in the figure, comprising: a frame 1, a worktable 2, a cutting component 3, and a blowing device 4. The worktable 2 is located in the middle of the frame 1, and pressure rollers are respectively provided on both sides of the worktable 2. The pressure rollers are mounted on the frame 1 via an adjusting frame to apply pressure to the roll paper on the worktable 2 to a certain extent, ensuring that it does not curl or warp, facilitating subsequent straight cutting. Simultaneously, the adjusting frame can effectively adjust for roll paper of different thicknesses, expanding its applicability. The cutting component 3 is located at the top of the worktable 2 and is mounted on the top of the frame 1. The blowing device 4 is located on the side of the frame 1, on the side of the worktable 2. A counter 5 is mounted on the frame 1, and the counter 5 is on the same horizontal line as the central axis of the worktable 2. A controller 6 is mounted on the side of the frame 1, and the controller 6 is connected to a motor 7, which provides power to the cutting component 3, the blowing device 4, the counter 5, and the controller 6. Counter 5 detects the length of the paper roll. When the paper roll reaches the predetermined length, it sends feedback to controller 6. Controller 6 drives the cutting assembly 3 to descend and cut the paper roll on workbench 2. After use, the controller drives the blowing device 4 to blow air to ensure the cleanliness of the workbench 2 surface.
[0023] The blowing device 4 includes nozzles 41, ducts 42, connecting pipes 43, and a fan 44. The fan 44 is electrically connected to a controller 6. The air outlet of the fan 44 is connected to the connecting pipe 43, and multiple ducts 42 are connected to the connecting pipe 43. The top of each duct 42 is connected to a matching nozzle 41. The multiple nozzles 41 are located on one side of the frame 1 via a bracket. The entire nozzle 41 blows the contaminants in one direction, improving cleaning efficiency and ensuring cleanliness. Furthermore, the nozzles 41 have pressurized air inlets inside to enhance the blowing force and increase the spray range. The nozzles 41 are trumpet-shaped, and the blowing range of the multiple nozzles 41 is larger than the area of the workbench 2. There are no gaps between the blowing areas of adjacent nozzles 41, ensuring complete coverage of the entire workbench 2.
[0024] Working Principle: Motor 7 powers all equipment, and the paper roll moves on the worktable 2 of the frame 1. When counter 5 detects that the paper roll is within a preset value range, it sends feedback to controller 6. Controller 6 then controls the cutting assembly 3 to move rapidly downwards to cut the paper roll on worktable 2. Simultaneously, during the cutting process, controller 6 drives fan 44 to deliver air to each nozzle 41. The air is pressurized by the nozzles and ejected, ensuring that the entire worktable 2 is free of debris, dust, and other contaminants during the cutting process. At the same time, controller 6 controls the cutting assembly 3 to move rapidly upwards, ensuring the entire operation is uninterrupted.
[0025] Example 2
[0026] This second embodiment is based on the first embodiment, and mainly elaborates on the cutting component. Specifically:
[0027] The cutting assembly 3 includes columns 31, slide rails 32, bolsters 33, mounting bases 34, and cutting blades 35. Two columns 31 are respectively installed on both sides of the frame 1. Each column 31 has a groove that fits into the slide rail 32, with the groove depth greater than the height of the slide rail 32 to ensure the bolster 33 is vertically and vertically limited within the groove, preventing it from derailing. The bolster 33 is slidably connected to the slide rail 32 and electrically connected to the controller 6. The two bolsters 33 are respectively mounted on the mounting base 34, which is equipped with cutting blades 35. The cutting blades 35 perform high-intensity cutting, and the vertical sliding of the bolsters 33 improves the cutting speed and ensures the paper roll length.
[0028] Working principle: Motor 7 supplies power to slide rail 33, while controller 6 controls slide ram 33. When counter 5 detects that the roll of paper on the worktable has reached a preset value, controller 6 drives slide ram 33 to slide down rapidly. When cutting blade 35 reaches worktable 2, it is at the same horizontal level as counter 5. Cutting blade 35 cuts the roll of paper on the worktable, ensuring that the value of each roll of paper is consistent. At the same time, after cutting is completed, counter 5 is reset to zero and starts counting again. Simultaneously, controller 6 drives slide ram 33 to move upward, separating it from worktable 2, ensuring that the roll of paper on the worktable moves normally.
