Through the arrangement of the first transmission belt 903 and the rotating shaft 904, when in use, the first transmission belt 903 serves as an intermediate transmission member to ensure that power is efficiently transmitted from the first motor 902 to the rotating shaft 904, which can effectively reduce energy loss during power transmission and improve transmission efficiency. At the same time, the gear transmission system can achieve a precise speed ratio, ensuring that the speed and torque of the roller 905 are synchronized with the rotating shaft 904, thereby improving the accuracy and stability of the cutting process.

[0031] Furthermore, the inner wall size of the cutting blade 908 is consistent with the outer wall size of the roller 905, and the spacer 909 is symmetrically arranged with respect to the central axis of the cutting blade 908. By arranging the cutting blade 908 and the spacer 909, when in use, the installation accuracy of the cutting blade 908 on the roller 905 is ensured by the matching of the sizes, which can reduce the deviation and jitter in the cutting process and improve the cutting accuracy.

[0032] Furthermore, there are multiple groups of blade slots 912 distributed at equal intervals on the outer wall of the driven roller 911, and the cutting blade 908 and the blade slots 912 are distributed in parallel. Through the setting of the blade slots 912, when in use, the equally distributed blade slots 912 can ensure the balance of the driven roller 911 during rotation, reduce vibration and shaking caused by uneven distribution, and improve the stability of the system. At the same time, the parallel distribution design can ensure that the cutting effect of each cutting point is consistent, reduce the scrap rate caused by inconsistent cutting, and further improve production efficiency.

The setting of the roller 1307 and the conveyor belt 1308. When in use, the second motor 1304 is started to drive the second transmission belt 1305 to rotate, thereby driving the driven wheel 1306 and the roller 1307 to rotate, so that the second transmission belt 1305 can reduce the direct contact between the second motor 1304 and the roller 1307, reduce wear, and extend the service life of the transmission mechanism 13. The second transmission belt 1305 rotates to drive the roller 1307, so that the driving gear set on the roller 1307 drives the driven gear connected to one side of the conveyor belt 1308 to rotate, so that the speed and torque of the roller 1307 can be kept consistent with the conveyor belt 1308, thereby improving the running accuracy of the conveyor belt 1308. The roller 1307 is fixedly connected to the conveyor belt 1308, which can ensure the stability and accuracy of the cut materials during the transportation process, so that the transmission mechanism 13 can achieve higher transmission efficiency, improve safety, optimize structural strength, enhance operational convenience, improve working environment and improve production efficiency.

[0034] Furthermore, the bearing plate 1302 is threadedly connected to the support plate 3 via a connecting gasket 1301, and the motor bracket 1303 is symmetrically arranged with respect to the central axis of the second motor 1304 body. Through the arrangement of the bearing plate 1302 and the motor bracket 1303, when in use, the threaded connection fixes the bearing plate 1302 to one side of the support plate 3, which can provide stability for the second motor 1304 during operation and reduce the risk of loosening and falling off caused by power output and vibration. The symmetrically arranged motor bracket 1303 can support the second motor 1304 and fix it on the bearing plate 1302. The fixed design of the bearing plate 1302 can evenly disperse the force generated by the second motor 1304 and the roller 1307 during operation, thereby improving the structural strength of the entire transmission mechanism 13.

[0035] Furthermore, the inner wall size of the second transmission belt 1305 is consistent with the outer wall size of the driven wheel 1306, and the roller 1307 forms a rotating structure with the second transmission belt 1305 through the second motor 1304. Through the setting of the second transmission belt 1305 and the roller 1307, when in use, the second motor 1304 is started to drive the second transmission belt 1305 and the roller 1307 to form a rotating structure, thereby ensuring the smooth operation of the roller 1307, reducing faults caused by uneven transmission, and further improving production efficiency.

[0036] Working principle: When the slitting machine is in use, it is adjusted according to work requirements. An external power supply supplies power to the entire system. Multiple groups of support columns 2 are symmetrically arranged at the bottom of the base 1, which can significantly enhance the overall stability of the equipment. Multiple groups of support columns 2 are evenly distributed to ensure that the equipment will not tilt or shake during operation, especially under high-speed operation and heavy load conditions, providing solid support. The symmetrically arranged support plates 3 can better withstand the pressure and shear force from above, ensuring that the equipment can maintain good structural integrity after long-term use. The straight plates 4 symmetrically arranged on the upper surface of the base are fixedly connected to the reel rotation rod 5, which can ensure that the position and angle of the reel are consistent during rotation, improve the conveying accuracy of the reel material, and reduce the offset and misalignment of the material. The straight plates 4 and the reel The rotating rod 5 jointly supports the reel, and the reel rotating rod 5 is driven by a motor to drive the reel to rotate and send the printed material into the cutting area. The motor support 901 is fixedly connected to the support plate 3 and the motor support 901, and provides a stable installation foundation for the first motor 902 to ensure the stability and reliability of the motor operation. The first motor 902 transmits power to the rotating shaft 904 through the first transmission belt 903, thereby achieving efficient power transmission and reducing energy loss. The rotating shaft 904 transmits power to the driving gear 906 and the driven gear 907 through the roller 905. The snap connection between the rotating shaft 904 and the roller 905 ensures the accurate position and movement trajectory of the cutting blade 908, improves the cutting accuracy, and also ensures the close fit of the components to avoid The risk of loosening and falling off, the roller 905 drives the active gear 906 to rotate, and the active gear 906 rotates to drive the driven gear 907. The gear transmission system can achieve accurate speed ratio and torque transmission to ensure the smooth and efficient cutting process. A cutting blade 908 is installed on the roller 905, and the cutting blade 908 is fixed on the roller 905 through a blade slot 912. The cutting blade 908 rotates under the drive of the roller 905 to cut the printed material entering the cutting area. Through the combination of the spacer 909 and the fastening column 910, the position of the cutting blade 908 can be accurately adjusted according to the scale 12 set above the support plate to ensure the stability and consistency of the cutting blade on different materials, and the cutting blade 908 can be moved by the driven roller 911 The blade slot 912 can be quickly replaced and adjusted to adapt to materials of different thicknesses and materials, thereby improving the flexibility and application range of the equipment. When the cutting of the material is completed, the second motor 1304 is started to drive the second transmission belt 1305 to rotate, thereby driving the driven wheel 1306 and the roller 1307 to rotate, so that the second transmission belt 1305 can reduce the direct contact between the second motor 1304 and the roller 1307, reduce wear, and extend the service life of the transmission mechanism 13. The second transmission belt 1305 rotates to drive the roller 1307, so that the driving gear set on the roller 1307 drives the driven gear connected to one side of the conveyor belt 1308 to rotate, so that the rotation speed and torque of the roller 1307 can be kept consistent with the conveyor belt 1308.Thereby improving the running accuracy of the conveyor belt 1308, and fixing the conveyor belt 1308 with the roller 1307 can ensure the stability and accuracy of the cut materials during the conveying process, so that the transmission mechanism 13 can achieve higher transmission efficiency and smoothly transport the cut materials. The model of the motor is YE2-132S-4, thus completing the use process of a printing slitting machine with adjustable spacing.
