After the upper pressing assembly is arranged, the upper pressing seat 138 and the bearing seat 131 of the upper pressing assembly clamp and fix the material 100, and as the material 100 needs to be carried for rotation, preferably, the lower end of the upper pressing seat 138 and the upper end of the bearing seat 131 are provided with raised heads or concave holes; in the technical scheme, the upper end of the supporting seat 131 is a supporting column, a concave hole is arranged on the upper end surface of the supporting column, and the lower shaft of the material 100 is inserted into the concave hole. The lower end of the upper pressing seat 138 is provided with a convex head which correspondingly props against the upper shaft of the material 100. The structure of the material 100 is mainly an axisymmetric structure, and the material 100 can be an automobile turbine or the like. To avoid the upper bearing 1310 from being exposed, a bearing housing lower cover 1313 is attached to the lower end thereof.

Further, the lower end of the transmission shaft 132 extends out of the rotating disc 15, the driving assembly includes a driven wheel 1321 disposed at the lower end of the transmission shaft 132, the driven wheel 1321 has a double-wheel structure, one driven wheel 1321 is a driving driven wheel 1321, and two adjacent driven wheels 1321 are connected by a single belt.

In order to enable the jig 13 on the rotary disk 15 to drive the material 100 to rotate under the drive of external force, the technical scheme is that driven wheels 1321 of a double-wheel structure are arranged at the lower ends of the driving shafts 132, two adjacent driving shafts 132 are connected through a belt, so that all the driving shafts 132 can be connected into a whole in sequence, and after the driving and driven wheels 1321 are driven, all other driven wheels 1321 are driven to rotate through the belt. Secondly, in the working process, the supporting seat 14 is in a static state, and the rotary disk 15 rotates under the transmission of the main shaft 12, namely, the rotary disk 15 and the supporting seat 14 relatively rotate; when the driven wheel 1321 is connected with the supporting seat 14 through a belt, the rotating disk 15 rotates, so that the angle and the position of the driven wheel 1321 on the transmission shaft 132 relative to the supporting seat 14 change, and the transmission shaft 132 rotates.

When many existing sand blasting devices are used for carrying out surface treatment on a material 100, the material 100 is firstly conveyed to a processing area through a conveying mechanism, then the conveying mechanism stops working and waits for a period of processing time of the material 100 in the processing area, and after the material 100 is processed, the conveying mechanism is started to convey the material 100 out of the processing area; the frequent start-stop operation mode has large impact on the electric network and the electronic equipment of the equipment, needs regular maintenance and sets related protection equipment or circuits, and has high cost; the material conveying mechanism 1 in the technical scheme can continuously work for a long time all the time without frequent interruption in work; in actual use, the transmission ratio can be adjusted through the transmission mechanism, so that the conveying speed of the material conveying mechanism 1 (the rotating speed of the rotating disk 15) is far smaller than the autorotation rotating speed of the transmission shaft 132, the conveying mechanism sequentially conveys the material 100 to the processing area, and the transmission shaft 132 always keeps rotating in the process; the material 100 is subjected to surface treatment by sand blasting of the spray gun mechanism 2 when passing through the processing area, and then is discharged out of the processing area; after all the products on the jigs 13 on the conveying mechanism are processed, the conveying mechanism stops, and the products on the jigs 13 are unloaded. The conveying mechanism is reset or directly carries out the next round of work. During this process, the material 100 is kept rotating and its angle and position are adjusted, so that its surface treatment is relatively uniform. Meanwhile, when the jig 13 rotates, a driving device is not additionally arranged, and the driving device of the material conveying mechanism 1 is adopted, so that the whole structure is simplified, and the cost is reduced.
