[0023] Specifically, the shunt end of the shunt pipe 15 is fixedly connected with the water inlet end of the two shower heads 16 penetrating through the top of the mounting frame 2, the water inlet end of the shunt pipe 15 is clamped with the water outlet end of the faucet or other water supply device, and a sealing ring is arranged at the connection between the water inlet end of the shunt pipe 15 and the water outlet end of the faucet or other water supply device.

[0024] Specifically, the top of the two first slide rods 4 penetrates through the positions near the center of the left and right sides of the inner top wall of the mounting frame 2 and extends out of the top of the mounting frame 2, and the connection between the first slide rod 4 and the mounting frame 2 is movably sleeved.

[0025] Specifically, the multiple second slide rods 8 are arranged in pairs on the two connecting plates 9, and the end away from the connecting plate 9 of the second slide rod 8 penetrates through the inside of the steady frame 6 and extends out of the outside of the steady frame 6, and the connection between the second slide rod 8 and the steady frame 6 is movably sleeved.

[0030] In use, according to the use of the cutting knife 11, if the knife is not sharp, the operator can quickly and conveniently connect the connecting end of the shunt pipe 15 to the water outlet end of the faucet or other water supply device and ensure stable clamping; then, by manually rotating the two handles, the threaded rod 7 can be driven to rotate in the stabilizing frame 6, which in turn drives the connecting plate 9, the spring 13, the fixed plate 12 and the whetstone 14 to gradually approach the front and rear ends of the cutting knife 11; this fine adjustment process will continue until the end of the whetstone 14 far from the fixed plate 12 is closely attached to the cutting knife 11, fully preparing for the subsequent knife grinding operation; once the whetstone 14 and the cutting knife 11 reach the ideal contact state, the operator can open the faucet or start other water supply devices, and at the same time start the air cylinder 5; the output end of the air cylinder 5 will powerfully drive the cutting knife 11 to move up and down in the vertical direction; in this dynamic process, the cutting edge of the cutting knife 11 will constantly contact the grinding surface of the whetstone 14, thereby evenly and effectively grinding the front and rear ends of the cutting knife 11 by the two whetstones 14; this setting not only ensures that the cutting knife 11 can quickly restore sharpness, but also greatly improves the efficiency and accuracy of knife grinding; it is worth noting that in the process of grinding the cutting knife 11, the cutting edge will exert a certain pressure on the two whetstones 14; this pressure will cause the spring 13 to be compressed accordingly, thereby generating a certain elastic reaction force; this elastic feedback mechanism not only helps to maintain the constant contact pressure between the whetstone 14 and the cutting knife 11, but also ensures the smooth progress of the grinding process; at the same time, the buffering effect of the spring 13 can effectively reduce the vibration and noise generated during grinding, further improving the grinding effect; at the same time, the water mist sprayed by the spray head 16 is evenly sprayed on the whetstone 14 and the cutting knife 11; this setting not only plays a significant cooling role, effectively reducing the heat generated during grinding, preventing overheating and oxidation of the cutting knife 11 and the whetstone 14; but also has multiple functions such as reducing wear, cleaning the surface, improving grinding accuracy, reducing dust and preventing sparks; the cutting knife 11 after polishing has a more delicate cutting edge, reducing the cutting resistance and making the cutting process smoother; at the same time, the sharp cutting edge can more effectively cut into the paper corner, reducing the cutting force and time, thereby improving work efficiency; after polishing is completed, the operator can rotate the handle again to restore the threaded rod 7, the fixed plate 12, the spring 13 and the whetstone 14 to their original positions; at the same time, turn off the faucet or other water supply device to save water resources and avoid unnecessary waste; the entire grinding process is quick, simple and efficient, without the need for additional complex operations or professional tools, and is very suitable for quick maintenance and maintenance on the production line or work site; in summary, the cutting equipment and its knife grinding device fully consider the convenience and efficiency of actual use, not only ensuring that the cutting knife 11 always remains sharp, but also greatly improving the overall work efficiency and quality;This kind of innovative setting provides strong support and guarantee for the cutting processing of paper corner guards and other materials.

[0031] In summary, the cutting device for paper corner guard production, by setting the threaded rod 7, fixed plate 12, spring 13 and whetstone 14, first, the cutting knife 11 can be quickly polished, by manually rotating the threaded rod 7, the distance between the whetstone 14 and the cutting knife 11 can be easily adjusted to make them in close contact, so as to quickly restore the sharpness of the cutting knife 11, this setting greatly shortens the time of sharpening the knife and improves the work efficiency, second, improves the accuracy and efficiency of sharpening, since the whetstone 14 is accurately adjusted by the threaded rod 7, therefore, the contact area and contact pressure between the whetstone 14 and the cutting knife 11 are uniform, so as to achieve more accurate grinding effect, at the same time, the elastic feedback mechanism of the spring 13 also helps to keep the grinding process smooth, further improves the efficiency and accuracy of sharpening, third, enhances the flexibility and adaptability of the device, the sharpening device composed of the threaded rod 7, fixed plate 12, spring 13 and whetstone 14 can be flexibly adjusted according to different cutting requirements and tool wear, this setting makes the device applicable to different types and specifications of cutting knives 11, improves its versatility and practicality, fourth, helps to protect the cutting knife 11 and the whetstone 14, the buffering effect of the spring 13 can reduce the vibration and noise generated by grinding, so as to prolong the service life of the cutting knife 11 and the whetstone 14, at the same time, the spraying of water mist also plays a cooling and lubricating role, further protects the surface quality of the cutting knife 11 and the whetstone 14.
