[0022] Embodiment 1

[0023] As Figures 1 - 3 shown, a carbide band saw blade tooth surface sandblasting machine proposed by the present utility model includes a machine body 1, a lifting frame 5 and a swinging assembly. Material inlets 2 for the band saw blade to pass through are provided at both ends of the machine body 1. Limiting wheels a 3 for supporting the band saw blade are symmetrically arranged inside the machine body 1. A hydraulic cylinder 4 is installed at the bottom of the machine body 1. A lifting frame 5 is movably arranged inside the machine body 1, which is connected to the output end of the hydraulic cylinder 4. Fixed frames 6 are provided on both sides of the top thereof. A horizontal shaft 7 is rotatably arranged inside the fixed frame 6. There are multiple groups of connecting sleeves 8 arranged linearly and equidistantly on the horizontal shaft 7. A sandblasting head 9 facing the band saw blade is arranged on the connecting sleeve 8. A swinging assembly for cooperating with the horizontal shaft 7 to drive the sandblasting head 9 to swing reciprocally is arranged at one end of the fixed frame 6.

[0024] As Figure 2 shown, cross plates 10 are connected to both ends of the machine body 1 and are located below the material inlets 2. Two groups of blocking posts 11 are symmetrically arranged on the cross plates 10. A channel for the band saw blade to be conveyed is arranged between the two groups of blocking posts 11. Limiting wheels b 12 installed on the cross plates 10 are arranged on the opposite sides of the two groups of blocking posts 11.

[0025] As Figure 2 and Figure 3 shown, through holes 13 are provided at the four corners of the lifting frame 5. Guide posts 14 are inserted into the four through holes 13. The bottom ends of the guide posts 14 are connected to the machine body 1. Anti-disengagement plates are connected to the top ends of the guide posts 14. The moving track of the lifting frame 5 is limited by the guide posts 14 to ensure the stability of its movement.

[0026] As Figure 2 shown, a material conveying hose 15 is arranged at the tail of the sandblasting head 9. The material conveying hose 15 is externally connected to a sand box through an external pump body.

[0027] The band saw blade is conveyed to the channel between the two stoppers 11 through the external conveying assembly. The band saw blade during the conveying process is supported by the cooperation of the limiting wheel a3 and the limiting wheel b12. The hydraulic cylinder 4 adjusts the lifting frame 5 to move to a specified height under the limitation of the guide post 14 according to the width of the band saw blade, so that the sand blasting head 9 thereon is located at the exact middle of the band saw blade. Then, the sand blasting material in the sand box is extracted through the external pump body and ejected through the sand blasting head 9.

[0028] Embodiment 2

[0029] As Figures 1 - 3 shown, a carbide band saw blade tooth surface sand blaster proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the specific components of the swinging assembly and its connection mode with the cross shaft 7.

[0030] As Figure 1 and Figure 2 shown, the swinging assembly includes a coupling shaft 16, a strip plate 17, a rotating shaft 18, a connecting disc 19, an inserting shaft 20 and a synchronous driving member. One end of the fixed frame 6 is symmetrically and rotatably connected with the rotating shaft 18 and the coupling shaft 16. One end of the coupling shaft 16 passes through the fixed frame 6 and is connected with the cross shaft 7, and its other end is connected with one end of the side surface of the strip plate 17. A through groove 21 is formed on the strip plate 17; one end of the rotating shaft 18 is connected with the connecting disc 19, and an inserting shaft 20 extending into the through groove 21 is arranged at the eccentric position of the side surface of the connecting disc 19. Synchronous driving members are arranged on the two rotating shafts 18.

[0031] As Figure 2 and Figure 3 shown, the synchronous driving member includes a motor 23, a synchronous pulley 24 and a belt 22.

The motor 23 is installed on the fixed frame 6, and its output end is connected with one group of the rotating shafts 18. The cooperation of the synchronous pulley 24 and the belt 22 enables the two groups of rotating shafts 18 to be driven to rotate synchronously when the motor 23 operates.

[0032] During the sand blasting process, the motor 23 is started. The motor 23 drives the two rotating shafts 18 to rotate synchronously under the cooperation of the synchronous pulley 24 and the belt 22. During the rotation of the rotating shaft 18, it drives the connecting disc 19 to rotate. When the connecting disc 19 rotates, it drives the inserting shaft 20 to do a circular motion. During the motion of the inserting shaft 20, it pushes the strip plate 17. The strip plate 17 drives the coupling shaft 16 and the cross shaft 7 to swing reciprocally within a certain angle under the thrust. During the swinging process, the cross shaft 7 drives the sand blasting head 9 to swing synchronously through the connecting sleeve 8. During the swinging process, it can ensure that the sand blasting medium can evenly cover each area on the surface of the band saw blade, avoiding the uneven sand blasting phenomenon caused by the fixed sand blasting head 9 and improving the sand blasting quality.
