Description

Technical Field

[0001] The present invention relates to the field of shot blasting machines, and specifically to a shot blasting machine that can facilitate internal cleaning. Background Technique

[0002] A shot blasting machine is a mechanical device widely used in metal surface treatment. It mainly projects media such as steel shots at high speed onto the surface of workpieces through a high-speed rotating shot blasting device, so as to achieve the effects of cleaning, strengthening, or polishing the metal surface. Surface cleaning: removing impurities such as oxide scales, rust, welding spatter, and sand mold residues on the metal surface; surface strengthening: generating compressive stress through shot blasting on the metal surface, thereby improving the fatigue resistance, corrosion resistance, and abrasion resistance of the metal; surface polishing: improving the smoothness of the metal surface and providing a smooth surface for subsequent processes such as painting and spraying.

[0003] When the existing shot blasting machine processes a plate, the plate is hung on a bracket through a hook. After placement, the plate will contact the crossbar of the suspension frame, and the contact part will result in poor polishing effect when polishing the plate. Moreover, when the suspension frame rotates, the plate will also shake, and the impact between the shaking plate and the suspension frame will cause dents or deformation on the surface of the plate. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a shot blasting machine that can facilitate internal cleaning to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A shot blasting machine that can facilitate internal cleaning, including a shot blasting machine body. A filter plate is fixed inside the shot blasting machine body, and a driving motor is arranged above the shot blasting machine body. And a cabinet door is arranged on one side of the shot blasting machine body. A gear is arranged on the top of the shot blasting machine body, and a fixing rod is fixed at the bottom of the gear. A first hook is fixed at the end of the fixing rod. A vertical rod is arranged below the first hook, and a fixing ring is fixed at the end of the vertical rod. Multiple crossbars are fixed on the outer wall of the vertical rod, and multiple sleeve rings are sleeved on the outer wall of the crossbars. And a second hook is fixed at the bottom of the sleeve ring. A rectangular rod is fixed at the bottom of the vertical rod, and an inner rod is movably installed at the bottom of the rectangular rod. A reciprocating lead screw is movably installed at the bottom of the inner rod, and a sliding sleeve is sleeved on the outer wall of the inner rod. A support rod is fixed at the bottom of the reciprocating lead screw. First limit rings are fixed at both ends of the sliding sleeve, and multiple first limit rods are fixed on the outer wall of the first limit rings. A second limit ring is sleeved on the outer wall of the rectangular rod, and multiple second limit rods are fixed on the outer wall of the second limit ring. A limiting component is arranged above the filter plate. A component for restricting the rotation of the sliding sleeve is arranged on the outer wall of the sliding sleeve, and the sliding sleeve is sleeved on the outer wall of the reciprocating lead screw.

[0006] By adopting the above technical solution, the problem that the existing shot blasting machine has poor grinding effect on the plate during operation is solved. By the cooperation of the reciprocating screw rod and the sliding sleeve, the sliding sleeve can slide up and down on the outer wall of the rectangular rod. When the sliding sleeve slides, it will drive the first limiting rod and the second limiting rod in contact with the plate to move up and down. Since the contact points of the first limiting rod and the second limiting rod with the plate are different, it is convenient to process the surface of the plate. At the same time, the first limiting rod and the second limiting rod cooperate with each other, so as to avoid the shaking of the plate during rotation and the problem of the shaking of the suspension bracket.

[0007] The present invention is further configured such that the limiting assembly includes a clamping block, a moving block, a connecting rod, a sliding block and a fixed sliding rod. A plurality of groups of clamping blocks are fixed on the top of the filter plate, and a moving block is movably installed on one side of the clamping block. A connecting rod is movably installed on the outer wall of the moving block, and a sliding block is movably installed at the end of the connecting rod. The sliding block is slidably connected to the fixed sliding rod, and the fixed sliding rod is fixed on the inner wall of the shot blasting machine body. A rectangular block is fixed at the end of the support rod, and a plurality of groups of grooves are formed on the outer wall of the rectangular block.

[0008] Preferably, the purpose of facilitating the limitation of the bottom of the suspension bracket is achieved. When the cabinet door is closed, it will drive the convex rod to move. The movement of the convex rod will drive two moving blocks to approach each other. When approaching, the distorted rectangular block can be corrected. The protrusion on one side of the moving block enters into the groove to limit the bottom of the suspension bracket, avoiding the abnormal noise caused by the shaking of the bottom of the suspension bracket. At the same time, it can also limit the bottom of the suspension bracket to avoid the problem that the bottom of the suspension bracket rotates.

[0009] The present invention is further configured such that convex blocks are fixed on both sides of the moving block, and a protrusion is fixed on the side of the moving block away from the connecting rod. The cross section of the protrusion is semicircular. A moving groove is formed on one side of the clamping block. The four corners of the rectangular block are arc-shaped. A second spring is sleeved on the outer wall of the fixed sliding rod, and both ends of the second spring are in contact with the sliding block and the fixed sliding rod.

[0010] Preferably, by the cooperation of the convex block and the moving groove, the movement direction of the moving block can be limited, so that the moving block slides between two clamping blocks. The setting of the protrusion can make the protrusion contact with the rectangular block when the moving block moves to one side, so as to correct the rectangular block. The arc-shaped protrusion can reduce the friction force with the rectangular block, so as to better correct the rectangular block. The setting of the second spring can squeeze the second spring when the sliding block slides on the outer wall of the fixed sliding rod, so as to facilitate the reset of the sliding block.

[0011] The present invention is further configured such that a sliding hole is formed in the sliding block, and the inner wall of the sliding hole is attached to the outer wall of the fixed sliding rod.

[0012] Preferably, the slider can slide directionally on the outer wall of the fixed sliding rod through the opened sliding hole.

[0013] The present invention is further configured such that a convex rod is fixed to one side of the slider, and the end of the convex rod is arc-shaped.

[0014] Preferably, the convex rod can contact the convex rod when the cabinet door is closed, and the bottom of the convex rod fits with the top of the filter plate. Therefore, when the cabinet door is closed, it will push the convex rod to move, and the arc-shaped end of the convex rod can reduce the friction with the cabinet door.

[0015] The present invention is further configured such that a rectangular hole is opened inside the second limiting ring, and the inner wall of the rectangular hole fits with the outer wall of the rectangular rod.

[0016] Preferably, the inner wall of the rectangular hole fits with the outer wall of the rectangular rod, so that the second limiting ring will not rotate, and the second limiting ring can only slide up and down on the outer wall of the rectangular rod.

[0017] The present invention is further configured such that the component for restricting the rotation of the sliding sleeve includes a plug rod. The plug rod passes through the sliding sleeve, and a first spring is sleeved on the outer wall of the plug rod. Both ends of the first spring are fixedly connected to the plug rod and the sliding sleeve, and a sliding groove is opened on the outer wall of the inner rod.

[0018] Preferably, the plug rod can be inserted into the inner wall of the sliding groove, so that when the rectangular rod rotates, it can drive the sliding sleeve to rotate. The end of the plug rod slides on the inner wall of the sliding groove, and the first spring limits the plug rod to avoid the problem that the plug rod will separate from the sliding sleeve.

[0019] The present invention is further configured such that a convex ring is fixed to the top of a group of the first limiting rings, and the convex ring is threadedly connected to the second limiting ring.

[0020] Preferably, a threaded groove is opened at the bottom of the second limiting ring, and the convex ring is threadedly connected to the threaded groove, which can avoid the problem that the first limiting ring will separate from the second limiting ring.

[0021] The present invention is further configured such that an avoidance hole is opened inside the convex ring, a sliding hole is opened inside the first limiting ring, and the diameter of the inner wall of the avoidance hole is larger than the diameters of the rectangular rod, the inner rod, and the support rod.

[0022] Preferably, the setting of the avoidance hole can prevent the first limiting ring from contacting the rectangular rod, enabling the first limiting ring to rotate. The inner wall of the sliding hole fits with the outer wall of the inner rod, enabling the sliding sleeve to slide on the outer wall of the inner rod. The inner wall of the first limiting ring at the bottom of the sliding sleeve fits with the outer wall of the support rod, enabling the first limiting ring at the bottom of the sliding sleeve to rotate around the support rod.

[0023] In summary, the present invention mainly has the following beneficial effects:

[0024] 1. The present invention solves the problem that the existing shot blasting machine has poor grinding effect on the plate during operation by providing a vertical rod, a horizontal rod, a second hook, a rectangular rod, a first limiting rod, a sliding sleeve and a second limiting rod. By the cooperation of the reciprocating lead screw and the sliding sleeve, the sliding sleeve can slide up and down on the outer wall of the rectangular rod. When the sliding sleeve slides, it will drive the first limiting rod and the second limiting rod in contact with the plate to move up and down. Since the contact points of the first limiting rod and the second limiting rod with the plate are different, it is convenient to process the surface of the plate. At the same time, the first limiting rod and the second limiting rod cooperate with each other to avoid the shaking of the plate during rotation and the problem of the shaking of the suspension bracket.

[0025] 2. The present invention achieves the purpose of facilitating the limitation of the bottom of the suspension bracket by providing a clamping block, a moving block, a connecting rod, a sliding block, a convex rod and a rectangular block. When the cabinet door is closed, it will drive the convex rod to move. The movement of the convex rod will drive two groups of moving blocks to approach each other. When approaching, the distorted rectangular block can be corrected. The protrusion on one side of the moving block enters the inside of the groove to limit the bottom of the suspension bracket, avoiding the abnormal noise caused by the shaking of the bottom of the suspension bracket. At the same time, it can also limit the bottom of the suspension bracket to avoid the problem that the bottom of the suspension bracket will rotate. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0044] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0045] Please refer to Figures 1 - 15, including a shot blasting machine body 1, a filter plate 8 is fixed inside the shot blasting machine body 1. The diameter of the filter holes above the filter plate 8 is larger, so that when the steel shots fall, they can fall better and avoid remaining above the filter plate 8. A driving motor 3 is arranged above the shot blasting machine body 1, and a cabinet door 2 is arranged on one side of the shot blasting machine body 1. A shot blasting device is arranged inside the shot blasting machine body 1 to process the surface of the plate. A gear 4 is arranged on the top of the shot blasting machine body 1, and a fixing rod 41 is fixed to the bottom of the gear 4. A first hook 42 is fixed to the end of the fixing rod 41. A vertical rod 5 is arranged below the first hook 42, and a fixing ring 55 is fixed to the end of the vertical rod 5. A plurality of cross rods 51 are fixed to the outer wall of the vertical rod 5, and a plurality of sleeves 52 are sleeved on the outer wall of the cross rods 51. The sleeves 52 and the cross rods 51 are connected by bearings to facilitate the rotation of the second hook 53. A second hook 53 is fixed to the bottom of the sleeve 52. A rectangular rod 54 is fixed to the bottom of the vertical rod 5, and an inner rod 56 is movably installed at the bottom of the rectangular rod 54. A reciprocating lead screw 91 is movably installed at the bottom of the inner rod 56, and a sliding sleeve 6 is sleeved on the outer wall of the inner rod 56. A support rod 9 is fixed to the bottom of the reciprocating lead screw 91. First limit rings 61 are fixed to both ends of the sliding sleeve 6, and a plurality of first limit rods 62 are fixed to the outer walls of the first limit rings 61. A second limit ring 7 is sleeved on the outer wall of the rectangular rod 54, and a plurality of second limit rods 71 are fixed to the outer wall of the second limit ring 7. The first limit rods 62 and the second limit rods 71 are both arranged as cylinders to reduce the contact area with the plate. A limiting component is arranged above the filter plate 8, and a component for restricting the rotation of the sliding sleeve 6 is arranged on the outer wall of the sliding sleeve 6. The sliding sleeve 6 is sleeved on the outer wall of the reciprocating lead screw 91. The gear 4, the fixing rod 41, the first hook 42, the vertical rod 5, the cross rod 51, the second hook 53, the fixing ring 55, the rectangular rod 54, the sliding sleeve 6, the first limit ring 61, the first limit rod 62, the second limit ring 7 and the second limit rod 71 form a suspension rack.

[0046] In the above embodiment, specifically, please refer to Figure 3 , Figure 4 , Figure 5 , Figures 10 - 12, the limiting component includes a clamping block 81, a moving block 82, a connecting rod 83, a sliding block 84 and a fixed sliding rod 85. Multiple groups of clamping blocks 81 are fixed on the top of the filter plate 8, and a moving block 82 is movably installed on one side of the clamping block 81. A connecting rod 83 is movably installed on the outer wall of the moving block 82, and a sliding block 84 is movably installed at the end of the connecting rod 83. The sliding block 84 is slidably connected to the fixed sliding rod 85, and the fixed sliding rod 85 is fixed on the inner wall of the shot blasting machine body 1. A rectangular block 92 is fixed at the end of the support rod 9, and multiple groups of grooves 93 are formed on the outer wall of the rectangular block 92. The two sides of the inner wall of the groove 93 are arc-shaped, which can facilitate the better entry of the protrusion 89 into the groove. The top of the clamping block 81 is inclined. When steel shots fall on the top of the clamping block 8, they will fall off, achieving the purpose of facilitating the limitation of the bottom of the suspension bracket. When the cabinet door is closed, it will drive the convex rod to move. The movement of the convex rod will drive the two moving blocks to approach each other. When approaching, the distorted rectangular block can be corrected. The protrusion on one side of the moving block enters the inside of the groove to limit the bottom of the suspension bracket, avoiding abnormal noise caused by the shaking of the bottom of the suspension bracket. At the same time, it can also limit the bottom of the suspension bracket to avoid the problem that the bottom of the suspension bracket will rotate.

[0047] In the above embodiment, specifically, please refer to Figure 5 , Figure 10 and Figure 11 , convex blocks 88 are fixed on both sides of the moving block 82, and a protrusion 89 is fixed on the side of the moving block 82 away from the connecting rod 83. The cross-section of the protrusion 89 is semicircular. A moving groove 811 is formed on one side of the clamping block 81. The four corners of the rectangular block 92 are arc-shaped. A second spring 86 is sleeved on the outer wall of the fixed sliding rod 85, and both ends of the second spring 86 are in contact with the sliding block 84 and the fixed sliding rod 85. By the cooperation of the convex block 88 and the moving groove 811, the movement direction of the moving block 82 can be limited, so that the moving block 82 slides between the two clamping blocks 81. The protrusion 89 can contact the rectangular block 92 when the moving block 82 moves to one side, thereby correcting the rectangular block 92. The arc-shaped protrusion 89 can reduce the friction with the rectangular block 92, so as to better correct the rectangular block 92. The setting of the second spring 86 can squeeze the second spring 86 when the sliding block 84 slides on the outer wall of the fixed sliding rod 85, so as to facilitate the reset of the sliding block 84.

[0048] In the above embodiment, specifically, please refer to Figure 5 and Figure 10 , a sliding hole 810 is formed inside the sliding block 84, and the inner wall of the sliding hole 810 fits with the outer wall of the fixed sliding rod 85. The formed sliding hole 810 enables the sliding block 84 to slide directionally on the outer wall of the fixed sliding rod 85.

[0049] In the above embodiment, specifically, please refer to Figure 1 ,Figure 3 , Figure 4 and Figure 5 , one side of the slider 84 is fixed with a convex rod 87, and the end of the convex rod 87 is arc-shaped. By setting the convex rod 87, it can contact the convex rod 87 when the cabinet door is closed. The bottom of the convex rod 87 fits against the top of the filter plate 8. Therefore, when the cabinet door 2 is closed, it will push the convex rod 87 to move. The arc-shaped setting of the end of the convex rod 87 can reduce the friction force with the cabinet door 2.

[0050] In the above-mentioned embodiment, specifically, please refer to Figure 6 and Figure 9 , a rectangular hole 72 is formed inside the second limiting ring 7, and the inner wall of the rectangular hole 72 fits against the outer wall of the rectangular rod 54. The inner wall of the rectangular hole 72 fits against the outer wall of the rectangular rod 54, so that the second limiting ring 7 will not rotate. The second limiting ring 7 can only slide up and down along the outer wall of the rectangular rod 54.

[0051] In the above-mentioned embodiment, specifically, please refer to Figures 6 - 9 , the component for restricting the rotation of the sliding sleeve 6 includes a plug rod 65. The plug rod 65 penetrates through the sliding sleeve 6, and a first spring 67 is sleeved on the outer wall of the plug rod 65. The two ends of the first spring 67 are fixedly connected to the plug rod 65 and the sliding sleeve 6. A chute 57 is formed on the outer wall of the inner rod 56. By setting the plug rod 65, it can be inserted into the inner wall of the chute 57. Thus, when the rectangular rod 54 rotates, it can drive the sliding sleeve 6 to rotate. The end of the plug rod 65 slides on the inner wall of the chute 57. The first spring 67 limits the plug rod 65 to avoid the problem that the plug rod 65 will separate from the sliding sleeve 6.

[0052] In the above-mentioned embodiment, specifically, please refer to Figure 9 , Figure 13 and Figure 14 , a convex ring 63 is fixed on the top of a group of first limiting rings 61, and the convex ring 63 is threadedly connected to the second limiting ring 7. A threaded groove 73 is formed at the bottom of the second limiting ring 7. The convex ring 63 is threadedly connected to the threaded groove 73, which can avoid the problem that the first limiting ring 61 will separate from the second limiting ring 7.

[0053] In the above-mentioned embodiment, specifically, please refer to Figure 4 , Figure 5 , Figures 13 - 15, a relief hole 64 is formed inside the convex ring 63, a sliding hole 66 is formed inside the sliding sleeve 6, and the diameter of the inner wall of the relief hole 64 is larger than the diameters of the rectangular rod 54, the inner rod 56 and the support rod 9. The arrangement of the relief hole 64 can prevent the first limiting ring 61 from contacting the rectangular rod 54, enabling the first limiting ring 61 to rotate. The inner wall of the sliding hole 66 fits with the outer wall of the inner rod 56, enabling the sliding sleeve 6 to slide on the outer wall of the inner rod 56. The inner wall of the first limiting ring 61 at the bottom of the sliding sleeve 6 fits with the outer wall of the support rod 9, enabling the first limiting ring 61 at the bottom of the sliding sleeve 6 to rotate around the support rod 9.

[0054] When the present invention is working specifically: when it is necessary to polish a plate, the plate is suspended on the outer wall of the second hook 53. The collar 52 is connected to the cross bar 51 by bearings. Therefore, when hanging the plate, only need to place the plate on one side of the second limiting rod 71. The second hook 53 passes through the through hole above the plate, and then release the plate to complete the hanging. Hang the plates in sequence, and then manually rotate the sliding sleeve 6. When the sliding sleeve 6 rotates, it will drive the first limiting rod 62 to rotate. When the second limiting rod 62 rotates, it will contact the plate. At this time, the plug rod 65 will drive the plug rod 65 to move under the action of the first spring 67. The end of the plug rod 65 enters the inner wall of the chute 57. The first limiting rod 62 and the second limiting rod 71 are located on both sides of the plate. Therefore, the plate can be better limited to prevent the plate from shaking when the vertical rod 5 rotates. Then connect the vertical rod 5 with the fixed rod 41. The first hook 42 at the bottom of the fixed rod 41 is connected to the fixed ring 55. The fixed rod 41 and the vertical rod 5 form a suspension rack. Then, the suspension rack is placed into the inside of the shot blasting machine body 1 through the suspension transfer device. The gear 4 meshes with the gear at the output end of the motor, and then close the cabinet door 2.

[0055] When the cabinet door 2 is closed, it will contact the convex rod 87. Therefore, the cabinet door 2 will squeeze the convex rod 87 to one side, and the convex rod 87 slides into the inside of the shot blasting machine body 1. The convex rod 87 drives the slider 84 to slide on the outer wall of the fixed slide bar 85. When the slider 84 slides, it will squeeze the second spring 86. At the same time, when the slider 84 slides, it will drive the end of the connecting rod 83 to move. The end of the connecting rod 83 pushes the moving block 82 to slide inside the clamping block 81. When the moving block 82 moves, it will drive the protrusion 89 to move. When the protrusion 89 contacts the rectangular block 92, the protrusion 89 can correct the rectangular block 92. The protrusion 89 enters the inner wall of the groove 93. One side of the moving block 82 contacts the outer wall of the rectangular block 92. The moving block 82 can limit the rectangular block 92 to avoid the problem that the bottom of the suspension rack shakes when rotating.

[0056] Subsequently, when the drive motor 3 operates, it drives the gear 4 to rotate. When the gear 4 rotates, it drives the fixed rod 41 to rotate. When the fixed rod 41 rotates, it drives the first hook 42 to rotate. When the first hook 42 rotates, it drives the vertical rod 5 to rotate. Therefore, it drives the sheet material to rotate. At this time, the shot blasting machine body 1 operates to process the surface of the sheet material. When the vertical rod 5 rotates, it drives the rectangular rod 54 to rotate. The rotation of the rectangular rod 54 drives the sliding sleeve 6 to rotate. Since the moving block 82 contacts the rectangular block 92, when the sliding sleeve 6 rotates, the rectangular block 92 does not rotate. The sliding sleeve 6 is sleeved on the outer wall of the reciprocating lead screw 91. When the sliding sleeve 6 rotates and the reciprocating lead screw 91 does not rotate, the sliding sleeve 6 will slide up and down on the outer wall of the reciprocating lead screw 91. When the sliding sleeve 6 slides up and down, it drives the first limit ring 61 and the second limit ring 7 to move up and down, so that the first limit rod 62 and the second limit rod 71 move up and down on both sides of the sheet material, avoiding the first limit rod 62 and the second limit rod 71 continuously contacting the same part of the sheet material, and the processing effect on the surface of the sheet material is better.

[0057] After the processing is completed, open the cabinet door. After the cabinet door is opened, it does not contact the convex rod 87. The second spring 86 drives the slider 84 to reset, so that the moving block 82 moves away from the rectangular block 92, and the suspension rack is taken out of the shot blasting machine body 1 through the suspension transfer device.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present invention, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
