Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting, in particular to a thermal paper cutting structure for a cash register. Background Art
[0002] In order to obtain the required paper length, the cash register is equipped with a thermal paper cutting device. This device usually consists of a cutting blade, a cutting seat and a motion control system. When the cash register prints the required information, the cutting seat will automatically move to the corresponding position, and the cutting blade will quickly cut the thermal paper to the predetermined length. After cutting, the user can easily remove the cut thermal paper and provide the customer with a checkout voucher or receipt.
[0003] For thinner thermal paper, if the inclination angle of the cutting blade is too large, the cutting force may be concentrated in a certain area of the paper, which may easily damage the coating of the paper and affect the printing quality. For thicker thermal paper, if the inclination angle of the cutting blade is too small, it may cause unclean cutting due to insufficient cutting force, affecting cash register efficiency and printing quality. The existing thermal paper cutting structure for cash registers cannot cope with thermal papers of different thicknesses because the inclination angle of the cutting blade cannot be adjusted, resulting in low maneuverability.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-5 , an embodiment provided by the utility model:
[0023] A thermal paper cutting structure for a cash register includes a workbench 1, a support frame 11 is fixedly connected to the surface of the workbench 1, a slider 2 is slidably connected to the surface of the support frame 11, an adjustment plate 21 is fixedly connected to the surface of the slider 2, a first motor 22 is fixedly connected to the surface of the support frame 11, a turntable 23 is fixedly connected to the output shaft of the first motor 22, an adjustment rod 24 is fixedly connected to the surface of the turntable 23, a cylinder 3 is fixedly connected to the lower surface of the adjustment plate 21, a connecting frame 32 is fixedly connected to the piston rod of the cylinder 3, a telescopic rod 31 is fixedly connected to the lower surface of the adjustment plate 21, and the telescopic rod The telescopic end of 31 is fixedly connected to the connecting frame 32, a second motor 33 is fixedly connected to the surface of the connecting frame 32, a rotating rod 34 is fixedly connected to the output shaft of the second motor 33, and a cutting blade 35 is fixedly connected to the surface of the rotating rod 34. The cutting structure can properly adjust the cutting angle to adapt to the cutting of papers of different thicknesses and ensure the cutting quality of thermal paper. At the same time, when the cutting blade 35 cuts thermal paper for a long time, friction and wear will cause the blade to overheat, affect the cutting effect, and even damage the thermal paper. By replacing the cutting blade 35 at a regular time, the phenomenon of damaging the thermal paper can be avoided.
[0024] Furthermore, an arc-shaped guide hole is opened on the surface of the support frame 11, and the slider 2 is in an arc shape. The slider 2 slides on the guide hole of the support frame 11, and the adjustment plate 21 changes the inclination angle of the adjustment plate 21 on the support frame 11 during the sliding process.
[0025] Furthermore, the adjustment plate 21 slides on the surface of the support frame 11 through the slider 2. The adjustment plate 21 changes its inclination angle on the support frame 11 during the sliding process, thereby changing the cutting angle of the cutting blade 35 on the paper, and cutting different thicknesses of paper at different angles.
[0026] Furthermore, a hole is formed at one end of the adjusting rod 24 away from the rotating disk 23, and the slider 2 is inserted into the hole of the adjusting rod 24. The hole of the adjusting rod 24 has the same shape as the slider 2, and the adjusting rod 24 drives the slider 2 to move through the hole.
[0027] Furthermore, the turntable 23 rotates on the support frame 11 through the output shaft of the first motor 22, and the turntable 23 drives the slider 2 to slide on the guide hole of the support frame 11 through the adjusting rod 24, thereby realizing the driving of the slider 2 during the movement process, without the need for manual position adjustment. By adjusting the slider 2, the angle of the adjustment plate 21 is adjusted, and then the cutting angle of the cutting blade 35 is adjusted.
[0028] Furthermore, the connecting frame 32 moves on the adjusting plate 21 through the output shaft of the cylinder 3, and the telescopic rod 31 guides the moving direction of the connecting frame 32. The cutting blade 35 moves on the adjusting plate 21 through the connecting frame 32. The cutting blade 35 cuts the thermal paper while moving downward. After the adjusting plate 21 changes its angle, the cutting angle of the cutting blade 35 will also change accordingly. At this time, the cutting blade 35 will tilt and move downward to cut the thermal paper.
[0029] Furthermore, the rotating rod 34 rotates on the connecting frame 32 through the output shaft of the second motor 33, and the cutting blade 35 rotates on the connecting frame 32 through the rotating rod 34. The cutting blade 35 is provided with four groups and is evenly distributed in a ring shape on the surface of the rotating rod 34. The rotating rod 34 rotates ninety degrees each time, thereby realizing the replacement of the cutting blade 35.
[0030] Working principle: The turntable 23 is driven to rotate by the output shaft of the first motor 22, and the turntable 23 drives the slider 2 to slide on the guide hole of the support frame 11 through the adjusting rod 24. The slider 2 changes the inclination angle of the adjusting plate 21 during the sliding process, thereby changing the cutting angle of the cutting blade 35 to the thermal paper. By changing the cutting angle of the cylindrical cutting blade 35, the thermal paper cutting structure for the cash register can cope with thermal papers of different thicknesses, thereby improving the mobility of the cutting structure.
[0031] After a set of cutting blades 35 have been cutting for a long time, in order to prevent the overheated cutting blades 35 from continuing to work, the output shaft of the second motor 33 drives the rotating rod 34 to rotate ninety degrees on the connecting frame 32. At this time, the rotating rod 34 rotates another set of cutting blades 35 to the working area to continue working, thereby preventing the overheated cutting blades 35 from damaging the thermal paper during the cutting process.
[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
