Roll paper cutting device

Abstract

The application discloses a roll paper cutting device. The roll paper cutting device adopts an improved opening and closing design. When paper cutting is required, the left semi-cylinder and the right semi-cylinder can be opened, and the left semi-cylinder and the right semi-cylinder can be closed after paper is put in, and then the paper can be cut with a blade. This design is more convenient for putting in roll paper, and it is also more convenient to change and cut other roll paper.

DETAILED DESCRIPTION OF EMBODIMENTS

(10) The embodiments of the present technology described herein are not intended to be exhaustive or to limit the technology to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art can appreciate and understand the principles and practices of the present technology.

(11) All publications and patents mentioned herein are hereby incorporated by reference. The publications and patents disclosed herein are provided solely for their disclosure. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate any publication and/or patent, including any publication and/or patent cited herein.

(12) As shown in FIG. 1-7, A roll paper cutting device, comprising a left semi-cylinder 1, a right semi-cylinder 2 and a cutting mechanism, wherein the lower end of the left semi-cylinder 1 and the lower end of the right semi-cylinder 2 are rotatably connected by a pin, so that the two can rotate and open relatively, and the upper ends of the left semi-cylinder 1 and the right semi-cylinder 2 are both extended with a flat plate 3, and the flat plate 3 located on the right semi-cylinder 2 is provided with a right plug-in groove 7, and the flat plate 3 located on the left semi-cylinder 1 is provided with a left plug-in groove 6, and the left plug-in groove 6 and the right plug-in groove 7 are arranged oppositely, and the top of the left plug-in groove 6 is provided with a connecting rod that penetrates the flat plate 3 and the left semi-cylinder 1, one end of the cutting mechanism is inserted into the left plug-in groove 6 and the upper plug-in slot 8, and the other end of the cutting mechanism cooperates with the right plug-in slot 7. When the flat plate 3 on the left semi-cylinder 1 and the flat plate 3 on the right semi-cylinder 2 are docked, they are inserted into the right plug-in slot 7. When the left semi-cylinder 1 and the right semi-cylinder 2 are rotated and docked, paper is placed between the two flat plates 3, and the left semi-cylinder 1 and the right semi-cylinder 2 can be moved to cut the paper through the cutting mechanism. Moreover, since the paper is between the two flat plates 3, the stability and accuracy of the cutting process are ensured.

(13) The cutting mechanism includes a lower plug-in plate 9, an upper plug-in plate 10, an L-shaped connecting plate 11 and a blade 12. The upper end of the lower plug-in plate 9 is provided with an upper plug-in plate 10, and an L-shaped connecting plate 11 is provided at the side connection of the lower plug-in plate 9 and the upper plug-in plate 10. One end of the L-shaped connecting plate 11 cooperates with the right plug-in slot 7. When the flat plate 3 on the left semi-cylinder 1 and the flat plate 3 on the right semi-cylinder 2 are docked, they are plugged into the right plug-in slot 7, the lower plug-in plate 9 is plugged into the left plug-in slot 6, the upper plug-in plate 10 is plugged into the upper plug-in slot 8, and a mounting slot 13 is provided in the L-shaped connecting plate 11. One end of the mounting slot 13 extends into the lower plug-in plate 9, and the blade 12 is installed in the mounting slot 13.

(14) The blade 12 and the mounting slot 13 are interference fit, so that the blade 12 is installed more firmly.

(15) A notch 14 is provided at the bottom of the left plug-in groove 6, and the notch 14 extends downward from the bump 4. An elastic plate 15 is provided in the middle of the notch 14, and a groove 16 is provided at the upper end of the elastic plate 15. A bump 4 is provided at the bottom of the lower plug-in plate 9. When the lower plug-in plate 9 is plugged into the left plug-in groove 6, the bump 4 is placed in the groove 16 to prevent the cutting mechanism from loosening during the cutting process.

(16) The width of the upper plug-in slot 8 is smaller than the width of the left plug-in slot 6.

(17) The outer walls of the left semi-cylinder 1 and the right semi-cylinder 2 are provided with anti-skid patterns 5, so that when the operator holds the left semi-cylinder 1 and the right semi-cylinder 2 for moving cutting, it can play an anti-skid role and can cut paper more accurately.

(18) In Embodiment 1, for the case where the web diameter is less than or equal to the diameter of the left semi-cylinder 1 and the right semi-cylinder 2:

(19) When in use, first put the roll paper on the left semi-cylinder 1 and the right semi-cylinder 2, and make one end of the roll paper located on one side of the cutting mechanism, then rotate the left semi-cylinder 1 and the right semi-cylinder 2 to merge, so that one end of the L-shaped connecting plate 11 is inserted into the right plug-in slot 7, and at the same time adjust the insertion depth so that there is a certain gap between the two flat plates 3, so that the paper of the roll paper is located between the two flat plates 3, and then push the left semi-cylinder 1 and the right semi-cylinder 2 to move along the roll paper, and the blade 12 will cut the paper of the roll paper, and because the left semi-cylinder 1 and the right semi-cylinder 2 are sleeved on the roll paper, this allows the device to move in a straight line, and on the other hand, the paper is located between the two flat plates 3, which also limits the shaking of the paper, so that the cutting device can cut more accurately and ensure stable cutting accuracy.

(20) When the blade 12 needs to be replaced, the blade 12 can be directly removed from the mounting slot 13 with pliers, and then replaced with a new blade 12.

(21) In Embodiment 2, wherein the web diameter is larger than the diameter of the left semi-cylinder 1 and the right semi-cylinder 2:

(22) When in use, first put the roll paper on the left semi-cylinder 1 and the right semi-cylinder 2, and make one end of the roll paper on one side of the cutting mechanism, then rotate the left semi-cylinder 1 and the right semi-cylinder 2 to merge them. Since the diameter of the roll paper is relatively large, one end of the L-shaped connecting plate 11 cannot be plugged into the right plug-in slot 7. Then make the paper of the roll paper stick to the side of the flat plate 3 on the left semi-cylinder 1, and then push the left semi-cylinder 1 and the right semi-cylinder 2 to move along the roll paper, and the blade 12 will cut the paper of the roll paper. Moreover, since the left semi-cylinder 1 and the right semi-cylinder 2 are sleeved on the roll paper, this device can move in a straight line. At the same time, when moving, try to make the paper stick to the side of the flat plate 3, so that the cutting device can cut more accurately and ensure stable cutting accuracy.

(23) When the blade 12 needs to be replaced, the blade 12 can be directly removed from the mounting slot 13 with pliers, and then replaced with a new blade 12.
