It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0023] See also Figure 1-5 , an embodiment provided by the utility model:

[0024] A sandpaper mechanism that can be automatically replaced includes a sandpaper machine body 1, a plurality of rotating rollers 111 are arranged on one side of the sandpaper machine body 1, and sandpaper 2 is movably installed on the outer surface of the plurality of rotating rollers 111, a plurality of paper changing mechanisms are fixedly installed on the outer surface of the bottom end of one side of the sandpaper machine body 1, and the plurality of paper changing mechanisms include a fixing frame 5, one end of the fixing frame 5 is fixedly connected to one side of the sandpaper machine body 1, and a limiting plate 9 is fixedly installed on one end of the fixing frame 5, a placing rod 912 is arranged on one side of the limiting plate 9, and a push plate 911 is movably installed on the outer surface of the placing rod 912, and a fixing frame 5 is fixedly connected to one side of the sandpaper machine body 1, and a fixing frame 5 is fixedly connected to one side of the sandpaper machine body 1, and a limiting plate 9 is fixedly installed on one end of the fixing frame 5, a placing rod 912 is arranged on one side of the limiting plate 9, and a push plate 911 is movably installed on the outer surface of the placing rod 912, and a fixing frame 5 is fixedly connected to one side of the fixing frame 5. A casing 811 is fixedly installed on the side outer surface, and two groups of fixing seats 814 are fixedly installed on the inner wall of the casing 811. The outer surfaces of the two groups of fixing seats 814 are both provided with circular through grooves, and a screw rod 812 is movably installed in the circular through groove. One end of the screw rod 812 is connected to a motor 815, and the motor 815 is fixedly connected to the fixing seat 814. A sliding seat 816 is movably installed on the outer surface of the screw rod 812, and the top of the sliding seat 816 is connected to a connecting plate 817, and one end of the connecting plate 817 is connected to a push plate 911. Multiple groups of sandpaper 2 are movably installed on the outer surface of the placement rod 912.

[0025] Furthermore, a protective plate 813 is fixedly installed on the top outer surface of the casing 811, and a slide groove is provided on the outer surface of the protective plate 813, in which a connecting plate 817 is movably engaged. The protective plate 813 can effectively prevent external objects or operators from accidentally contacting the internal moving parts, such as the screw rod 812 and the sliding seat 816, thereby improving the safety of the equipment. The slide groove plays a limiting role, so that the connecting plate 817 can move accurately.

[0026] Furthermore, the bottom ends of the fixed frames 5 in the multiple paper changing mechanisms are respectively fixedly mounted with the first support rod 3 and the second support rod 4, and the first support rod 3 and the second support rod 4 are fixedly connected to the sandpaper machine body 1. The addition of the first support rod 3 and the second support rod 4 not only enhances the stability of the paper changing mechanism, but also ensures the firm connection between the paper changing mechanism and the sandpaper machine body 1, making the entire mechanism more stable and reliable during operation.

[0027] Furthermore, an annular groove is provided on the outer surface of the limit plate 9, and a screw rod 6 is installed in the annular groove, one end of the screw rod 6 is connected to the placement rod 912, and a thread is provided on the outer surface of the screw rod 6, and a locking ring 7 is movably installed on the outer surface of the screw rod 6. The locking ring 7 is tightly combined with the screw rod 6 through the thread on its outer surface to ensure the stability of the placement rod 912 when it is in a fixed position.

[0028] Furthermore, multiple sets of handles 8 are fixedly installed on the outer surface of the locking ring 7, and one end of the multiple sets of handles 8 is arc-shaped. The design of the handles 8 makes it easier to adjust and fix the locking ring 7, and the arc-shaped end makes the handles 8 comfortable to hold.

[0029] Furthermore, the outer surface of the push plate 911 is wrapped with rubber, which not only increases the friction between the push plate 911 and the sandpaper 2 to prevent the sandpaper 2 from slipping during the pushing process, but also reduces the wear on the surface of the sandpaper 2 and extends its service life.

[0030] Furthermore, the placement rod 912 and the rotating roller 111 are parallel to each other. The parallel design ensures the accuracy of the sandpaper 2 during the pushing and installation process, and avoids installation difficulties or poor effects caused by angle deviation.

[0031] Working principle: First, the operator needs to manually remove the old sandpaper 2 installed on the rotating roller 111. This step can be done by simply peeling or sliding the old sandpaper. Then, the operator starts the motor 815 fixedly connected to the fixed seat 814. The start of the motor 815 will drive the screw 812 connected to it to rotate. The rotation of the screw 812 will cause the sliding seat 816 installed on its outer surface to perform linear motion. The movement trajectory of the sliding seat 816 is controlled by the rotation direction and speed of the screw 812. The sliding seat 816 is connected to the push plate 911 through the connecting plate 817. Therefore, when the sliding seat 816 moves under the drive of the screw 812, the push plate 911 will also slide on the outer surface of the placement rod 912 accordingly. A plurality of groups of sandpaper 2 to be replaced are pre-placed on the placement rod 912. The sliding of the push plate 911 will push the sandpaper 2 on the placement rod 912 to move forward. Since the placement rod 912 is parallel to the rotating roller 111, the pushed sandpaper 2 can smoothly contact and align with the outer surface of the rotating roller 111. As the push plate 911 continues to push, the new sandpaper 2 will be pushed to the position of the rotating roller 111 and automatically installed on the outer surface of the rotating roller 111.

[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.
