Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model provides the following technical solution:

[0022] As attached Figures 1-4 As shown, this utility model discloses a sandblasting machine, including a worktable 12. The worktable 12 is equipped with a feeding mechanism 1, a conveying mechanism 2, a loading mechanism 3, a clamping mechanism 4, and a sandblasting mechanism 5. The feeding mechanism 1 holds a workpiece 6 to be processed. The feeding mechanism 1 conveys the workpiece 6 to the conveying mechanism 2, and the conveying mechanism 2 conveys the workpiece 6 to the loading mechanism 3. The clamping mechanism 4 presses the workpiece 6 towards the sandblasting mechanism 5, ensuring the workpiece 6 is tightly pressed against the sandblasting mechanism 5. The loading mechanism 3 drives the workpiece 6 to rotate. Specifically, in this design, by setting up the feeding mechanism 1, conveying mechanism 2, loading mechanism 3, clamping mechanism 4, and sandblasting mechanism 5, the sandblasting process of the workpiece 6 can be further automated, thereby improving work efficiency and processing quality.

[0023] Further, the feeding mechanism 3 comprises a feeding sliding power source 7, a feeding rotating power source 8, a feeding sliding seat 9, a feeding rotating seat 10 and a feeding transmission member 11. The feeding sliding power source 7 and the feeding sliding seat 9 are both arranged on the workbench 12, and the feeding sliding seat 9 is in sliding connection with the workbench 12. The feeding sliding power source 7 drives the feeding sliding seat 9 to move towards the sanding mechanism 5. The feeding rotating seat 10 is rotatably arranged at the top end of the feeding sliding seat 9. The feeding rotating power source 8 is arranged on the feeding rotating seat 10, and has an output shaft. The feeding transmission member 11 has a transmission end 13 and a connecting end 14. The transmission end 13 is connected with the output shaft, and the connecting end 14 is connected with the workpiece 6. In this embodiment, the feeding transmission member 11 is connected with the workpiece 6 through the connecting end 14, so that the workpiece can rotate stably and uniformly under the drive of the feeding rotating power source 8. The rotation of the feeding rotating seat 10 enables the workpiece to receive the polishing of the sanding mechanism 5 in all directions during the machining process, thereby improving the machining efficiency and the uniformity of the workpiece surface. The cooperative work of the feeding sliding power source 7 and the feeding rotating power source 8 ensures the accurate position control and stable conveying of the workpiece during the machining process, thereby improving the working performance and machining quality of the sanding machine. In addition, by optimizing the design of the feeding mechanism 3, the sanding machine reduces energy consumption while improving production efficiency, thereby meeting the demand for automation and high efficiency in modern industrial production.

[0024] Further, the feeding transmission member 11 includes a first transmission rod 15 and a second transmission rod 16. The first transmission rod 15 is connected with the output shaft and arranged coaxially with the output shaft. The first transmission rod 15 is provided with a first wedge-shaped end 17 at an end away from the output shaft. The second transmission rod 16 is provided with a second wedge-shaped end 18. The first wedge-shaped end 17 and the second wedge-shaped end 18 are both provided with corresponding annular inclined surfaces 19. The annular inclined surfaces 19 are welded and fixed between each other. The connecting end 14 is arranged at an end of the second transmission rod 16 away from the first transmission rod 15. Specifically, in this embodiment, through this structural design, the first transmission rod 15 and the second transmission rod 16 can effectively transmit power. At the same time, the annular inclined surfaces 19 of the first wedge-shaped end 17 and the second wedge-shaped end 18 cooperate to ensure the stability and reliability of transmission. The welding and fixing between the annular inclined surfaces 19 further enhances the strength and durability of the transmission member, reducing the risk of wear and damage under high load working conditions. The connecting end 14 is arranged at an end of the second transmission rod 16 away from the first transmission rod 15, so that the workpiece 6 to be processed can be firmly fixed, and under the driving of the feeding rotating power source 8, the workpiece can realize accurate positioning and stable rotation. This design not only improves the processing efficiency of the sanding machine, but also guarantees the processing quality, meeting the demand for automation and high efficiency in industrial production. The included angle between the first transmission rod 15 and the second transmission rod 16 is obtuse, so when the first transmission rod 15 rotates to drive the second transmission rod 16 to rotate, the second transmission rod 16 rotates around the first wedge-shaped end 17 of the first transmission rod 15. This arrangement can effectively disperse the stress in the transmission process and avoid fatigue damage of the transmission rod due to stress concentration. In addition, the coaxial structure design of the first transmission rod 15 and the output shaft ensures the efficiency and synchronization of power transmission, thereby improving the working efficiency of the entire sanding machine.

[0025] Further, the feeding slide 9 is further provided with a material blocking unit and a positioning member 20.

The blocking cylinder 23 is installed on the fixing plate 21. The blocking plate 22 is connected with the blocking cylinder 23. The blocking plate 22 is provided with a material discharging hole 24. In the process of moving the blocking plate 22 driven by the blocking cylinder 23, the part of the blocking plate 22 close to the material discharging hole 24 pushes the workpiece 6 to be processed to fall from the feeding transmission member 11. Specifically, in the embodiment, the material blocking unit can take out the workpiece on the feeding transmission member 11 which has completed sanding. The taking-out process is as follows: after the workpiece completes sanding, the blocking cylinder 23 on the fixing plate 21 moves the blocking plate 22 towards the workpiece, so as to take out the workpiece sleeved on the feeding transmission rod from the feeding transmission rod. The workbench 12 in the design is provided with a material collecting groove. The workpiece taken out from the feeding transmission rod falls into the material collecting groove and is collected. Such structure makes the whole feeding process more automatic, reduces manual intervention and improves production efficiency. At the same time, due to the accurate control of the material blocking unit, the positioning of the workpiece when taken out from the feeding transmission rod is more accurate, which avoids the collision and damage of the workpiece in the taking-out process and guarantees the quality of the workpiece. In addition, the design of the material collecting groove not only facilitates the collection of the workpiece, but also facilitates the subsequent classification and storage work. Overall, the design realizes the efficient, stable and safe operation of the sanding machine through the ingenious mechanical structure.

[0026] Further, the pressing mechanism 4 comprises a pressing slide 25, a pressing cylinder 26, a pressing motor 27 and a pressing wheel 28.

The pressing motor 27 is arranged on the pressing slide 25. One end of the pressing motor 27 is connected with the pressing wheel 28 and drives the pressing wheel 28 to rotate. Specifically, in the embodiment, the arrangement of the pressing mechanism 4 can press the workpiece 6 to be processed on the sanding belt 36, so that the workpiece 6 tightly contacts the sanding belt 36 for sanding, thereby ensuring uniform treatment of the surface of the workpiece. During the pressing process, the pressing slide 25 is driven by the pressing cylinder 26 to move towards the sanding mechanism 5. At this time, the pressing motor 27 drives the pressing wheel 28 to rotate. The pressing wheel 28 is in close contact with the workpiece. Through the rotation of the pressing wheel 28, the workpiece is uniformly pressed on the sanding belt 36. The design of the pressing mechanism 4 not only improves the sanding efficiency, but also ensures the uniformity and consistency of the surface treatment of the workpiece. In addition, the automatic control of the pressing mechanism 4 reduces the labor intensity of the operator, and avoids the damage to the workpiece caused by improper manual operation. Through precise mechanical cooperation and control, the pressing mechanism 4 provides a strong guarantee for the stable operation of the sanding machine.

[0027] Further, the feeding mechanism 1 comprises a feeding guide rail 29 and a feeding protection rod 30. One side of the workbench 12 is provided with a vibration disc (not shown in the figure).

The feeding protection rod 30 is fixed at the lower part of the feeding guide rail 29. Specifically, in the embodiment, the design of the feeding mechanism 1 aims to ensure that the workpiece can be smoothly and safely transmitted from the vibration disc to the feeding mechanism 2. The vibration disc can effectively disperse the workpieces from the stacked state through its vibration function, avoiding the adhesion or blockage between the workpieces. The feeding guide rail 29 serves as a transmission channel to guide the workpiece to move along the predetermined path to the feeding mechanism 2. In order to prevent the workpiece from falling or flying out during the transmission process, the feeding protection rod 30 is fixed at the lower part of the feeding guide rail 29 to form a safety barrier. In addition, the two ends of the feeding guide rail 29 are respectively connected with the vibration disc and the feeding mechanism 2, ensuring the continuity and stability of the entire feeding process. Through this structural design, the feeding mechanism 1 not only improves the transmission efficiency of the workpiece, but also ensures the smooth progress of the entire processing process.
