A threaded tube 6 is provided at the top of the end of the rotating belt 3 away from the fixed frame 1.

[0029] refer to Figure 1-5As shown, a through hole 201 is opened at the inner center of the conveyor belt 2 for rotation, and baffles 202 are fitted on both sides of the conveyor belt 2. The side section of the fixed frame 1 is mouth-shaped, and a collecting plate 101 is provided at the bottom of the fixed frame 1 away from the end of the rotating belt 3 and inclined toward the top. The collecting plate 101 corresponds to the bottom of one end of the conveyor belt 2; a first connecting rod 301 is provided at both ends of the rotating belt 3 for extrusion, and a second connecting rod 302 is installed at the center of the rotating belt 3. The inner ends of the threaded tube 6 are threadedly connected with threaded rods 601, and the threaded rod 601 at one end of the threaded tube 6 is rotatably connected to the outer wall of the second connecting rod 302 through a rotating ring 602; the outer wall of the electric push rod 4 for pushing is fixedly connected to the fixed frame 1, and the inner protruding end of the electric push rod 4 is fixedly connected to a connecting block 401. The two connecting blocks 401 are respectively fixedly connected to the first connecting rod 301 and the second connecting rod 302 at one end of the rotating belt 3, and the two connecting blocks 401 are parallel to each other.

[0030] refer to Figure 3 、 Figure 5 As shown, the bottom of the rotating belt 3 is fitted with the top of the conveyor belt 2, and the bottom outer walls of the first connecting rod 301 and the second connecting rod 302 are rotatably connected to the rotating wheels. The bottom outer walls of the first connecting rod 301 and the second connecting rod 302 are rotatably connected to the inner wall of the rotating belt 3 through the rotating wheels. The inner end of the rotating belt 3 away from the electric push rod 4 is inclined toward the edge of the conveyor belt 2, and the top side of the first connecting rod 301 away from the electric push rod 4 is fixedly connected to the threaded rod 601. The inner ends of the threaded tube 6 have opposite thread directions. Since the end of the rotating belt 3 away from the fixed frame 1 is inclined toward the edge of the conveyor belt 2, the inclined rotating belt 3 can drive the aluminum workpiece to move toward the center of the conveyor belt 2, thereby keeping the position of the aluminum workpiece centered during sandblasting, and thus keeping multiple aluminum workpieces in the same position during processing without manual readjustment, and the electric push rod 4 can also be started to drive the connecting block 401 to move, so as to adjust the distance between the two rotating belts 3.

[0031] refer to Figure 1 、 Figure 3 As shown, rotating rollers are provided at both ends of the interior of the conveyor belt 2, and one end of the rotating roller passes through the interior of the baffle 202 and is installed with a driving motor, and both ends of the interior of the fixed frame 1 near the bottom of the conveyor belt 2 are penetrated and rotatably connected with cleaning rollers 102, and both ends of the cleaning roller 102 pass through the interior of the fixed frame 1 and are rotatably connected to the baffle 202, and one end of the cleaning roller 102 is installed with a rotating motor, which can start the cleaning roller 102 to rotate, thereby cleaning the surface of the conveyor belt 2.

[0032] refer to Figure 5As shown, the outer wall of the second connecting rod 302 is rotatably connected to the threaded rod 601 through a rotating ring 602, and the internal threaded connection of the side wall of the rotating ring 602 is provided with an extrusion bolt 603. One end of the extrusion bolt 603 passes through the interior of the rotating ring 602 and fits with the second connecting rod 302. The extrusion bolt 603 can be rotated to release the fixation of the rotating ring 602, so as to facilitate the adjustment of the position of the threaded rod 601 around the rotating ring 602, and then adjust the position angle of one end of the rotating belt 3, so as to block the aluminum workpiece placed at an angle and meet the different usage requirements of the aluminum workpiece.

[0033] refer to Figure 1 、 Figure 4 As shown, the interior of the fixed frame 1 is provided with a plurality of through holes which are mutually engaged with the nozzle 5. Both sides of the top of the fixed frame 1 are threadedly connected with fixing bolts 502 at the corresponding positions of the nozzle 5. One end of the fixing bolt 502 passes through the interior of the fixed frame 1 and fits with the outer wall of the nozzle 5, and the interior of the rotating nozzle head 501 is connected with the nozzle 5.

[0034] Working principle: When in use, the aluminum workpiece to be processed can be conveniently placed on the surface of the conveyor belt 2 near one end of the rotating belt 3, and then the conveyor belt 2 is started to rotate, so that the aluminum workpiece moves to one side of the fixed frame 1, and then after the aluminum workpiece reaches the inside of the fixed frame 1, the external air pump equipment is started to convey the material to the nozzle 5, and then the sandblasting material is used to perform surface sandblasting on the aluminum workpiece through the rotating nozzle 501. At the same time, when processing aluminum workpieces of different sizes, the fixing bolt 502 can be conveniently rotated to release the fixation of the nozzle 5, and the height and position of the nozzle 5 can be conveniently adjusted up and down or rotated, thereby driving the position angle of the rotating nozzle 501 to be adjusted, and the angle of the rotating nozzle 501 can be rotated to further adjust the sandblasting position to adapt to different aluminum workpieces. When processing aluminum workpieces of different sizes or with skewed placement positions, since the rotating belt 3 is tilted toward the edge of the conveyor belt 2 away from the end of the fixed frame 1, the tilted rotating belt 3 can drive the aluminum workpiece to move toward the center of the conveyor belt 2, thereby keeping the position of the aluminum workpiece centered during sandblasting, and thus keeping multiple aluminum workpieces in the same position during processing without manual readjustment, and the electric push rod 4 can also be started to drive the connecting block 401 to move, so as to adjust the distance between the two rotating belts 3 to adapt to aluminum workpieces of different sizes, and at the same time, the extrusion bolt 603 can be rotated to release the fixation of the rotating ring 602, so as to facilitate the adjustment of the position of the threaded rod 601 around the rotating ring 602, and then adjust the position angle of one end of the rotating belt 3 to block the aluminum workpiece with skewed placement and meet the different usage requirements of aluminum workpieces.

[0035] During sandblasting, the through hole 201 on the outside of the conveyor belt 2 can facilitate the sandblasting material to leak to the bottom after use, which is convenient for collection. At the same time, a collection plate 101 is provided at the bottom of the fixed frame 1 away from the end of the rotating belt 3 and tilted toward the top. Since the collection plate 101 corresponds to the bottom of one end of the conveyor belt 2, when the conveyor belt 2 rotates to the end tilted toward the bottom, the sandblasting material on its surface can fall off and be collected by the collection plate 101. The cleaning roller 102 can also be started to rotate, thereby cleaning the surface of the conveyor belt 2, keeping it clean and avoiding adhesion, and no manual cleaning is required, which is more convenient.

[0036] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
