[0039] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0040] As Figures 1-5 shown, a shot blasting cleaning machine for spring processing includes a box body 1, a material storage box 2, a shot blasting machine 3, a driving roller 4, a guiding roller 5, a shot blasting track 6, a tensioning device, a screen 8, a vibration device, a waste residue box 9 and a shot material recovery box 10. A material discharge port 11 is provided on the side wall of the box body 1 for placing and taking workpieces, and a sealing door 12 is rotatably connected at the material discharge port; the material storage box 2 is fixed on the top of the box body for placing shot materials; the shot blasting machine 3 is arranged below the material storage box and is connected to the material storage box for spraying shot materials; both ends of the driving roller 4 are rotatably connected to the side wall of the box body and are driven by a motor; two guiding rollers 5 are selected, one is arranged directly below the driving roller, and the other is located on one side of the driving roller, and both ends of it are rotatably connected to the side wall of the box body; the shot blasting track 6 is sleeved on the driving roller and the guiding roller; the screen 8 is inclined and arranged directly below the shot blasting track; the waste residue box 9 is arranged directly below the screen for collecting impurities; the shot material recovery box is arranged at the bottom of the box body.

[0041] Specifically, the vibration device includes support columns 71, a support plate 72, a sleeve 73, a first elastic member 74, a connecting plate 75, a rotating shaft 76, a cam 77 and a vibration driving member 78. Four support columns 71 are selected and are fixed on the bottom of the screen; the support plate 72 is fixed on the inner wall of the box body; the sleeve 73 is fixed on the support plate, and one end of the support column extends into the sleeve; the first elastic member 74 is a spring, and one end of it is fixed inside the sleeve; the connecting plate 75 can slide up and down relative to the inner wall of the sleeve and is fixed on the end of the first elastic member; the rotating shaft 76 is rotatably connected to the side wall of the box body; the cam 77 is fixed on the rotating shaft; the vibration driving member 78 is a motor, and its output shaft is connected to the rotating shaft. Then, when shot blasting, the vibration driving member is started to drive the cam to rotate, and the end of the cam will intermittently contact the screen, thereby intermittently pushing the screen upward, so as to shake the screen and ensure the filtering effect. And under the action of the first elastic member, the vibration will be more intense, further improving the vibration filtering effect.

[0042] In other embodiments, the vibration device further includes a second elastic member 791, a top plate 793, a connecting column 794, a chute, a protective cover 797 and a roller 796. The connecting column 794 is rotatably connected to the bottom of the support column; the chute is opened on the connecting plate and can be inserted and slid by the connecting column, so that the support column is connected to the connecting plate, making the screen fall back faster; the second elastic member 791 is a spring, and one end of it is fixed on the side wall of the sleeve; the top plate 793 is fixed on the end of the second elastic member; the roller 796 is rotatably connected to the top plate, and the roller can contact the support column. Since the screen is inclined, the cam will give the screen a force in the horizontal direction during rotation, which can drive the screen to shake left and right. The left and right shaking can be intensified by the push of the second elastic member, further improving the filtering effect; the protective cover 797 is frustum-shaped and is fixed on the support column to prevent sundries from falling into the sleeve.

[0043] Specifically, the tensioning device includes a tensioning wheel 61, a connecting shaft 62, an adjusting block 63, a fixing plate 64 and a threaded rod 65. The connecting shaft 63 is connected to the adjusting block. The tensioning wheel 61 is rotatably connected to the end of the connecting shaft. A through groove 13 is provided on the side wall of the box body. The through groove allows the connecting shaft to move up and down. A sealing plate 621 is provided on the connecting shaft 62, and a plug-in groove 131 for inserting the sealing plate is provided on the side wall of the through groove. The fixing plate 64 is fixed on the side wall of the box body. The threaded rod 65 is rotatably connected to the fixing plate. The adjusting block is provided with a threaded hole that cooperates with the threaded rod. By rotating the threaded rod, the adjusting block can be driven to move up and down, and then the tensioning wheel can be driven to move up and down, so as to realize the tensioning of the shot blasting track.

[0044] In other embodiments, the tensioning device further includes a groove 631, a guiding column 67, a slider 68 and a third elastic member 69. The groove is opened on the adjusting block. Both ends of the guiding column 67 are fixed to the groove. The slider 68 can slide up and down relative to the guiding column. One end of the connecting shaft is fixed to the slider. The third elastic member 69 is selected as a spring, which is sleeved on the guiding column, and one end of it is fixed to the slider and the other end is fixed to the guiding column. By pushing the slider through the third elastic member, automatic fine adjustment of the tensioning wheel can be realized, so that the shot blasting track remains tensioned.

[0045] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
