[0002] Sanding is an indispensable and crucial process in industrial manufacturing, woodworking, and surface treatment, widely used for deburring, smoothing surfaces, chamfering, and preparing for subsequent coating or electroplating. Whether manual or automated, sandpaper is the consumable material that comes into direct contact with the workpiece.

[0003] In practical use, different models of sandpaper belts have different sizes and grits. When sanding, it is often necessary to select different models of sandpaper belts according to the needs. Existing sandpaper machines are not convenient for automatic replacement of sandpaper belts, nor are they convenient for installing and replacing sandpaper belts of different models. Therefore, a sanding belt polisher with automatic sanding belt replacement is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a belt sander with automatic belt replacement, which solves the problem that different models of sandpaper belts have different sizes and grits. When sanding, it is often necessary to select different models of sandpaper belts according to the needs. Existing sanders are not convenient for automatic replacement of sandpaper belts and for installing and replacing different models of sandpaper belts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic belt sander includes a first mounting bracket, a second mounting bracket fixedly connected above the first mounting bracket, a cylinder fixedly connected inside the second mounting bracket, two connecting air ports fixedly connected at equal intervals on one side of the cylinder, the cylinder including a push rod, and the cylinder drives the push rod to extend and retract, and a connecting plate fixedly connected above the push rod.

[0006] Furthermore, a limiting rail is fixedly connected to the outer side of the cylinder, and a limiting block is fixedly connected to the inner side of the connecting plate. The limiting block is movably sleeved on the outer side of the limiting rail.

[0007] Furthermore, a fixing rod is fixedly connected to the outer side of the connecting plate, a second bearing is provided on the outer side of the fixing rod, the inner ring of the second bearing is fixedly connected to the fixing rod, and an auxiliary wheel is fixedly connected to the outer ring of the second bearing.

[0008] Furthermore, a mounting plate is fixedly connected to the top of the first mounting bracket, a motor is fixedly connected to one side of the first mounting bracket, a first transmission rod is fixedly connected to the output end of one side of the motor, a coupling is fixedly sleeved on the outer side of the first transmission rod, and a second transmission rod is fixedly sleeved on the inner side of the coupling.

[0009] Furthermore, a first bearing is provided on the outer side of the second transmission rod, the inner ring of the first bearing is fixedly connected to the second transmission rod, the outer ring of the first bearing is fixedly connected to the inner wall of the first mounting bracket, a transmission wheel is snapped onto the outer side of the first bearing, a limit bolt is threadedly connected to one end of the first bearing, and the inner side of the limit bolt abuts against the transmission wheel.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the addition of an auxiliary wheel, facilitates the replacement of sandpaper belts of different models, simplifying the use of sanding machines and improving work efficiency. The sandpaper belt is fitted onto the outside of the auxiliary wheel and the drive wheel. Activating the external gas system drives the push rod inside the cylinder through the connecting air port.

[0020] like Figures 1-6 As shown, an automatic belt sander includes a first mounting bracket 2, a second mounting bracket 10 fixedly connected above the first mounting bracket 2, a cylinder 11 fixedly connected inside the second mounting bracket 10, and two connecting air ports 12 fixedly connected at equal intervals on one side of the cylinder 11. The cylinder 11 includes a push rod 13, and the cylinder 11 drives the push rod 13 to extend and retract. A connecting plate 16 is fixedly connected above the push rod 13. By adopting the above technical solution, the internal pipeline of the cylinder 11 can be connected through the connecting air ports 12, and the external gas system can drive the push rod 13 inside the cylinder 11 to move through the connecting air ports 12.

[0021] A limiting rail 14 is fixedly connected to the outer side of the cylinder 11, and a limiting block 15 is fixedly connected to the inner side of the connecting plate 16. The limiting block 15 is movably sleeved on the outer side of the limiting rail 14. By adopting the above technical solution, a groove is opened on the outer side of the limiting rail 14, and it can cooperate with the limiting block 15 to limit the limiting block 15 to always move linearly along the direction of the limiting rail 14 on the limiting rail 14. The length of the limiting track 14 is designed, and the range of motion of the push rod 13 pushing the connecting plate 16 is designed. During the movement, the connecting plate 16 can always drive the limiting block 15 to remain sleeved on the limiting track 14.

[0022] A fixing rod 17 is fixedly connected to the outer side of the connecting plate 16. A second bearing 18 is provided on the outer side of the fixing rod 17. The inner ring of the second bearing 18 is fixedly connected to the fixing rod 17. An auxiliary wheel 19 is fixedly connected to the outer ring of the second bearing 18. By adopting the above technical solution, the auxiliary wheel 19 can rotate about the fixing rod 17 as the axis through the second bearing 18. Furthermore, a limit baffle is installed on the outer side of the auxiliary wheel 19, which allows the sandpaper belt to be more securely attached to the auxiliary wheel 19 and is less likely to fall off.

[0023] A mounting plate 1 is fixedly connected to the top of the first mounting bracket 2. A motor 3 is fixedly connected to one side of the first mounting bracket 2. A first transmission rod 4 is fixedly connected to the output end of one side of the motor 3. A coupling 5 is fixedly sleeved on the outer side of the first transmission rod 4. A second transmission rod 6 is fixedly sleeved on the inner side of the coupling 5. By adopting the above technical solution, the interior of the first mounting bracket 2 is hollow, and the first transmission rod 4, coupling 5, and second transmission rod 6 are all set inside the first mounting bracket 2. The first transmission rod 4 and the second transmission rod 6 can be linked by the coupling 5. Mounting plate 1 has mounting holes on its outer side, which makes it easy to connect and fix the mounting plate 1 to external moving equipment such as robotic arms.

[0024] A first bearing 7 is provided on the outer side of the second transmission rod 6. The inner ring of the first bearing 7 is fixedly connected to the second transmission rod 6, and the outer ring of the first bearing 7 is fixedly connected to the inner wall of the first mounting bracket 2. A transmission wheel 8 is snapped onto the outer side of the first bearing 7. One end of the first bearing 7 is threadedly connected to a limit bolt 9, and the inner side of the limit bolt 9 abuts against the transmission wheel 8. By adopting the above technical solution, the transmission wheel 8 can be fixed from the outside by the limit bolt 9, making the transmission wheel 8 more securely fixed on the second transmission rod 6. The auxiliary wheel 19 and the transmission wheel 8 are positioned correspondingly, and the sandpaper belt can be fitted onto the outside of the auxiliary wheel 19 and the transmission wheel 8; The outer side of the drive wheel 8 is made of wear-resistant, high-friction material, which can easily drive the sandpaper belt.

[0025] It should be noted that during use, the mounting plate 1 is fixedly installed on the external moving equipment, and the sandpaper belt is sleeved on the outside of the auxiliary wheel 19 and the transmission wheel 8. The external gas system is started, which drives the push rod 13 in the cylinder 11 to move through the connecting air port 12. The push rod 13 moves upward, driving the connecting plate 16 to move. The connecting plate 16 drives the limit block 15 to move on the limit track 14. At the same time, the connecting plate 16 drives the auxiliary wheel 19 to move through the fixing rod 17 and the second bearing 18. The auxiliary wheel 19 gradually moves away from the transmission wheel 8, and then the auxiliary wheel 19 and the transmission wheel 8 together tighten the sandpaper belt to the required tightness, thus completing the installation of the sandpaper belt. The reverse operation can be used to disassemble it.

[0026] When sanding is needed, the motor 3 is started. The motor 3 drives the transmission wheel 8 to rotate through the first transmission rod 4, the coupling 5 and the second transmission rod 6. The transmission wheel 8 drives the sandpaper belt to rotate. The second transmission rod 6 can rotate in the first bearing 7 and the auxiliary wheel 19 can rotate on the second bearing 18. The sandpaper belt sands in motion.
