[0028] The outer side of the supporting cylinder 200 is provided with an elastic part, the elastic part can clamp the roller outside the supporting cylinder 200, so as to limit the position of the roller and ensure the stability of the roller. The elastic part comprises four elastic strips 600 mounted between the cylinder body 230 and the cylinder block 240, the four elastic strips 600 are evenly arranged around the axis of the roller shaft 210, and the middle part of the elastic strip 600 is protrudingly arranged away from the axis of the roller shaft 210.

[0029] It can be understood that one end of the elastic strip 600 is mounted on the barrel 230, and the other end is mounted on the barrel block 240. Due to the protrusion of the middle part of the elastic strip 600, the distance between the middle part of the elastic strip 600 and the axis of the roller 210 is greater than the distance between the outer peripheral surface of the barrel block 240 and the axis of the roller 210, so that the middle part of the elastic strip 600 is protrudingly arranged relative to the outer peripheral surface of the barrel block 240.

[0030] Wherein, the two ends of the elastic strip 600 are bent to form mounting sections 610, the length direction of the mounting sections 610 is perpendicular to the axis direction of the roller 210. The opposite sides of the barrel 230 and the barrel block 240 are both provided with notches, the notches are provided with insertion holes perpendicular to the axis direction, the mounting sections 610 at the two ends of the elastic strip 600 are respectively inserted into the corresponding insertion holes of the barrel 230 and the corresponding insertion holes of the barrel block 240, so that the two ends of the elastic strip 600 are respectively mounted on the barrel 230 and the barrel block 240.

It can be understood that the roller 210 can rotate relative to the two vertical plates 110.

[0032] In use, the roller with the crimped pressure sensitive paper is sleeved outside the supporting barrel 200, the elastic strip 600 can abut against the inner wall of the roller, so as to limit the rotation of the roller relative to the supporting barrel 200. In addition, the elastic strip 600 can also abut against the position of one end of the roller, so that the roller is limited to abut against the position of the other vertical plate 110, so as to adapt to the installation and fixation of rollers with different lengths and different radii. When the pressure sensitive paper is pulled, the center line of the rotation of the roller can be guaranteed to be the axis of the roller 210. The annular positioning grooves 220 can limit the movement of the roller 210 relative to the vertical plate 110 in the length direction of the roller 210, guarantee the stability of the roller 210 in the rotating movement, and prevent the end of the roller 210 from being separated from the support of the vertical plate 110.

[0033] In other embodiments, the number of elastic strips 600 can also be set to two, three, five, or six, etc. The elastic part can also be an oval ring outside the support cylinder 200. After pressing the two ends of the corresponding long axis of the oval ring, the oval ring can be deformed to be close to a circle to be placed in the support cylinder. The two ends of the corresponding long axis of the oval ring are in contact with the inner side wall of the cylinder, so that the position of the cylinder can be limited.

[0034] The top surface of the bottom plate 100 is provided with a first pressing plate 300, which is detachably mounted on the bottom plate 100 by bolts. The length direction of the first pressing plate 300 is parallel to the axis direction of the roller shaft 210, and the bottom surface of the first pressing plate 300 is provided with a recess, so that a first gap is formed between the bottom surface of the first pressing plate 300 and the top surface of the bottom plate 100, and the pressure sensitive paper can pass through the first gap. The top of the first pressing plate 300 is provided with an embedding groove and a slide rail strip 310, the bottom of the slide rail strip 310 is inserted into the embedding groove, and a plurality of countersunk holes are provided in the length direction of the slide rail strip 310.

The two inner side walls of the through groove 510 protrude to form protrusions 520, and the protrusions 520 are matched and embedded with the slide grooves 311. That is, the sliding block 500 can be inserted into the slide rail strip 310 from one end of the slide rail strip 310, and the cooperation of the protrusions 520 and the slide grooves 311 can make the sliding block 500 stably slide on the slide rail strip 310 in the length direction of the slide rail strip 310, and can only slide out from the two ends of the slide rail strip 310, so as to prevent the sliding block 500 from derailing in the middle of the slide rail strip 310, and to ensure the stability of the sliding block 500. In addition, the bottom surface of the sliding block 500 is in contact with the top surface of the first pressing plate 300, so as to further improve the sliding stability of the sliding block 500.

The bottom of the cutting knife 530 is inserted into the cutting groove 560.

[0037] When the roller is installed, one end of the pressure sensing paper is pulled out and passes through the first gap. The cutting position of the pressure sensing paper is determined according to the required length, and the cutting position is aligned with the cutting groove 560. Then, the sliding block 500 is pulled to slide on the sliding rail 310, and the cutting knife 530 cuts the pressure sensing paper, thereby cutting the pressure sensing paper of the required length. Because the sliding block 500 has a guiding function, the cutting process of the cutting knife 530 is very smooth and has high precision. The cutting knife 530 is not easy to deviate, and the operation is convenient. The cutting efficiency and quality of the pressure sensing paper can be improved.
