Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When in use, start the first motor 32. When the output end of the first motor 32 rotates, the rotating roller 31 connected thereto rotates accordingly, thereby causing the conveyor belt 33 to rotate, and then the rotation of the conveyor belt 33 causes the other rotating roller 31 to rotate accordingly. Then, the casting valves are placed on the top of the placement table 42 in sequence, and the casting valves are transported by the rotation of the conveyor belt 33. When it is necessary to remove the placement table 42 and the threaded rod 41 from the top of the conveyor belt 33, it is only necessary to rotate the threaded rod 41 to detach them from the inside of the mounting hole 9. The operation is simple.

[0025] A clamping mechanism is provided on the side of one of the placement platforms 42, which is located on the top of the baffle 2 and is used to clamp and fix the cast valve. The holding mechanism includes a second motor 51, a bidirectional screw 52, ​​a moving block 53, a connecting rod 54 and a clamping plate 55. A fixed plate 10 with a rectangular distribution on the top of the baffle 2 is welded to the side of one of the placement platforms 42. The second motor 51 is installed on one side of the fixed plate 10 by bolts. The output end of the second motor 51 is fixedly connected to the bidirectional screw 52 through a rotating shaft. The other end of the bidirectional screw 52 penetrates the fixed plate 10 and is rotatably connected to the inside of the other fixed plate 10 through a bearing seat.

The two moving blocks 53 are hingedly connected to the connecting rod 54 on the side close to the placement platform 42, and the other end of the connecting rod 54 is hingedly connected to the side of the clamping plate 55.

[0026] During use, when the casting valve is transported between the clamping plates 55, the second motor 51 is controlled to start at the same time, and when the output end of the second motor 51 rotates, the bidirectional screw 52 is driven to rotate accordingly, so that the two moving blocks 53 connected on the surface thereof move away from each other, and when the moving blocks 53 move, the clamping plate 55 is moved toward the casting valve on the top of the placement table 42 through the connecting rod 54, thereby clamping and fixing the casting valve so that it will not easily move during the sandblasting process.

[0027] The top surface of the clamping plate 55 is provided with a protective mechanism for protecting the cast valve during sandblasting, and the protective mechanism includes a support frame 61, a hydraulic rod 62 and a protective cover 63. The top surface of the clamping plate 55 is welded with a support frame 61 located on the top of the baffle 2, and a hydraulic rod 62 is symmetrically installed on one side of the support frame 61 close to the clamping plate 55. The top surfaces of the movable ends of the hydraulic rods 62 are fixedly installed on the top of the protective cover 63, and the side walls of the protective cover 63 are made of transparent materials to facilitate observation of the working conditions inside the protective cover 63. When in use, while the clamping plate 55 clamps the side of the cast valve, the hydraulic rod 62 is started, and its movable end is extended so that the protective cover 63 moves toward the surface of the conveyor belt 33, thereby covering the clamping plate 55 and the clamped cast valve inside the protective cover 63, so that the abrasive will not splash everywhere during the subsequent sandblasting operation.

[0028] The protective cover 63 is provided with an adjustment mechanism for adjusting the angle of sandblasting of the casting valve, and the adjustment mechanism includes a torsion spring 71, a fixing rod 72, an electric push rod 73 and a fixing block 74. The inner bottom surface of the protective cover 63 is welded with a torsion spring 71, and the other end of the torsion spring 71 is welded to the fixing rod 72 located above the clamping plate 55. The inner side of the protective cover 63 is connected with an electric push rod 73 by bolts, and the top surface of the movable end of the electric push rod 73 is fixedly installed on one side of the fixing rod 72. The bottom surface of the fixing rod 72 is symmetrically welded with a fixing block 74. The fixed block 74 is provided with a spraying mechanism for sandblasting the casting valve, and the spraying mechanism includes a connecting pipe 81, a nozzle 82, and a nozzle 83. , sandblasting tube 83, material storage box 84 and sandblasting machine 85, the interior of the fixed block 74 is slidably connected with a connecting tube 81, one end of the connecting tube 81 extends to the bottom surface of the fixed block 74 and is connected to the nozzle 82 by threaded rotation, the other end of the connecting tube 81 extends to the top surface of the fixed block 74 and is connected to one end of the sandblasting tube 83 through an adapter, a material storage box 84 is installed on the top of the support frame 61, one side of the material storage box 84 is connected to the sandblasting machine 85 located on the top of the support frame 61 through a pumping pipe, the end of the sandblasting tube 83 away from the connecting tube 81 passes through the protective cover 63 and is connected to one side of the sandblasting machine 85, and the sandblasting tube 83 and the connecting tube 81 are both set as plastic hoses.

[0029] A feed port is installed on the top of the storage box 84, and abrasive enters the storage box 84. When in use, the sandblasting machine 85 is first started. The sandblasting machine 85 pumps the abrasive in the storage box 84 into the sandblasting tube 83 through the pumping tube, and then transports it into the nozzle 82 through the connecting tube 81, and then sprays it out from the nozzle 82, so as to impact and grind the chips on the casting valve, thereby achieving the function of cleaning the surface of the casting valve. In the process of the nozzle 82 spraying the casting valve, the electric push rod 73 can be controlled to operate. The operation of the electric push rod 73 continuously pushes the fixed rod 72 to move in the horizontal direction, so that the fixed block 74 drives the nozzle 82 to move through the connecting tube 81. When the electric push rod 73 pushes the fixed rod 72 to move, the end of the torsion spring 71 connected to the fixed rod 72 is pulled, so that the nozzle 82 can continuously adjust the angle of its spraying abrasive during the spraying operation, thereby improving practicality.

[0030] Working principle: When preparing to use the casting valve sandblasting device, the operator first starts the first motor 32 to control the operation of the conveying mechanism, and then places the casting valves on the top of the placement table 42 in sequence. When the casting valve is transported to the clamping plate 55 through the conveyor belt 33, the second motor 51 controls the operation of the clamping mechanism, so that the clamping plate 55 clamps and fixes the side of the casting valve. At the same time, the movable end of the hydraulic rod 62 extends so that the protective cover 63 covers the clamping plate 55 and the casting valve inside it. Then the sandblasting machine 85 conveys the abrasive in the storage box 84 into the connecting pipe 81 through the pumping pipe and the sandblasting pipe 83, and then sprays it from the nozzle 82. While the nozzle 82 sprays the abrasive, the electric push rod 73 operates, so that the fixed block 74 in the adjustment mechanism drives the nozzle 82 to move, so that the nozzle 82 can continuously adjust the angle of its spraying abrasive during the spraying of the casting valve, thereby improving the practicality and work efficiency of the casting valve sandblasting device and facilitating the use of the operator.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
