[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1: As Figures 1-3As shown, a roll-type thermal paper slitting device includes a frame 1, a guide roller 2, a cutting mechanism 3, a leveling mechanism 4, a feeding roller 5, and a take-up roller 6. The guide roller 2 and the cutting mechanism 3 are respectively disposed inside the frame 1. The feeding roller 5 and the take-up roller 6 are respectively disposed on both sides of the frame 1. The feeding roller 5 is located on the side closer to the guide roller 2. The feeding roller 5 is wound with wide thermal paper to be slit, and the take-up roller 6 is wound with narrow thermal paper after slit. The leveling mechanism 4 is disposed between the guide roller 2 and the cutting mechanism 3. The leveling mechanism 4 includes a leveling roller 41, a telescopic component 42, and a leveling component 43. The leveling roller 41 is rotatably disposed inside the frame 1. The telescopic component 42 is disposed above the leveling roller 41. The leveling component 43 is fixed to one end of the telescopic component 42 near the leveling roller 41. The leveling component 43 is bent toward the leveling roller 41 to form an arc. The length of the leveling component 43 is the same as the length of the leveling roller 41. The frame 1 is also equipped with a controller, which can control the cutting mechanism 3, the leveling mechanism 4, the feeding roller 5 and the winding roller 6 respectively.

[0026] When the slitting device is idle or in preparation, the telescopic component 42 is in a retracted state, leaving a wide channel between the flattening component 43 and the flattening roller 41. One end of the wide thermal paper is passed sequentially through the guide roller 2, the aforementioned channel, and the cutting mechanism 3. The telescopic end of the telescopic component 42 is then extended until the channel between the flattening component 43 and the flattening roller 41 just accommodates the thermal paper. The cutting mechanism 3 is then adjusted, and finally, the narrow-width thermal paper is wound up by the winding roller 6. Because this device guides the paper using the guide roller 2 before slitting and simultaneously flattens both ends of the wide thermal paper using the flattening mechanism 4, it can largely avoid deviations in the slitting position, resulting in a better slitting effect.

[0027] like Figure 2 As shown, the telescopic assembly 42 includes an electric telescopic rod 421, a crossbar 422, and guide blocks 423. The crossbar 422 is fixed to one side of the telescopic end of the electric telescopic rod 421. There are two guide blocks 423, each fixed to one end of the crossbar 422. Slide grooves are symmetrically formed on the inner wall of the frame 1 along the telescopic direction of the electric telescopic rod 421. Each guide block 423 is slidably connected to one of the slide grooves. A flattening component 43 is fixed to the telescopic end of the electric telescopic rod 421. During the telescopic process of the electric telescopic rod 421, it is guided by the crossbar 422, guide blocks 423, and slide grooves. Preferably, the crossbar 422 is orthogonally arranged to the electric telescopic rod 421.

[0028] like Figure 4As shown, the flattening component 43 includes a base plate 431 and a movable plate 432. A plurality of springs 433 are evenly distributed between the base plate 431 and the movable plate 432. The two ends of each spring 433 are fixed to the base plate 431 and the movable plate 432, respectively. A guide seat 434 is provided on the side of the base plate 431 near the movable plate 432, and a guide rod 435 is provided on the side of the movable plate 432 near the base plate 431. The guide rod 435 is movably connected to the guide seat 434. The end face of the movable plate 432 away from the base plate 431 is in contact with one end face of the wide-width thermal paper. The springs 433 cushion the movement of the movable plate 432, and the guide rod 435 and the guide seat 434 limit the direction of movement of the movable plate 432.

[0029] like Figure 5 As shown, the guide seat 434 includes a housing, and a wide cavity and a narrow cavity are provided in the housing. The narrow cavity is located on the side of the wide cavity close to the moving plate 432. The guide rod 435 includes a straight rod and a protrusion. The protrusion is fixed to one end of the straight rod, and the other end of the straight rod is fixed to the end face of the moving plate 432. The protrusion slides in contact with the wide cavity, and the straight rod slides in contact with the narrow cavity.

[0030] like Figure 2 , Figure 3 As shown, the cutting mechanism 3 includes a rotating frame 31, a cutting blade 32, a cutting roller 33, and a motor 34. The rotating frame 31 is rotatably mounted on the frame 1, the cutting blade 32 is fixed on the rotating frame 31, the output shaft of the motor 34 is connected to the rotating shaft of the rotating frame 31, and the cutting roller 33 is rotatably mounted inside the frame 1, located below the cutting blade 32. When the slitting device is idle or in the preparation stage, a relatively wide gap is left between the cutting blade 32 and the cutting roller 33. After the wide thermal paper passes through the gap, the output shaft of the motor 34 is rotated, which in turn drives the rotating frame 31 to rotate until the cutting blade 32 can just slit the wide thermal paper.

[0031] like Figure 5 As shown, the rotating frame 31 includes a fixed base and rotating plates symmetrically installed at both ends of the fixed base. The frame body 1 has symmetrically opened channels for the fixed base to pass through. The ends of the two rotating plates furthest from the fixed base are rotatably connected to the outer wall of the frame body 1. The output shaft of the motor 34 is connected to one of the rotating plates. Rotation of the output shaft of the motor 34 drives one of the rotating plates to rotate, which in turn drives the fixed base and the other rotating plate to rotate.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
