Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine feeding devices, and in particular to an automatic feeding device for shot blasting equipment. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. It can simultaneously complete the sand removal, core removal, and surface cleaning of castings. In some regions, it is also colloquially known as a sandblasting machine or sandblasting machine. Almost all cast steel parts, gray castings, malleable iron parts, and ductile iron parts need to undergo shot blasting treatment. This process not only removes oxide scale and adhering sand from the surface of castings, but is also an indispensable preparatory step before the quality inspection of castings. For example, before non-destructive testing, the casing of a large steam turbine must undergo strict shot blasting to ensure the reliability of the test results. In the conventional casting production process, shot blasting is a key process for discovering surface defects in castings, and can effectively detect problems such as subcutaneous porosity, slag porosity, adhering sand, cold shuts, and peeling.

[0003] Currently, most shot blasting feeding devices have not yet achieved precise centering of the material, which can easily cause the material to deviate from the center position, resulting in incomplete shot blasting and ultimately affecting the integrity and uniformity of the surface treatment. Therefore, we propose an automatic feeding device for shot blasting equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic feeding device for shot blasting equipment, which solves the problem that current shot blasting feeding devices fail to achieve centered positioning of materials, resulting in incomplete shot blasting cleaning.

[0010] As a further technical solution of this utility model, a shot blasting box is connected to the upper surface of the protective box, and protective curtains are fixedly connected to the two mutually distant sides of the shot blasting box.

[0013] This utility model provides an automatic feeding device for shot blasting equipment, which has the following advantages compared with the prior art: 1. This design discloses an automatic feeding device for shot blasting equipment. Two first motors drive corresponding first guide plates to rotate, while an electric push rod extends and retracts, causing a movable ball to rotate flexibly within the circular hole of the connecting block. The combined effect of these two motors precisely controls the angle of the second guide plate, forming a symmetrical and flexibly adjustable guiding force. This effectively corrects the material's deviation, ensuring it is precisely centered on the conveying path. This solves the problem of incomplete shot blasting caused by positioning deviation at its source, significantly improving the uniformity and integrity of the surface treatment. Furthermore, the arrangement of the second and third drive rollers creates a smooth downward trend for the conveyor belt, ensuring the stability of the material during transport and preventing secondary deviation due to bumps. This, combined with the guiding and positioning structure, provides a more stable material posture for subsequent shot blasting, further enhancing the reliability of the overall processing flow.

[0017] Please see Figure 1-5 This utility model provides a technical solution for an automatic feeding device for shot blasting equipment: It includes a base plate 1, with a protective box 2 connected to the upper surface of the base plate 1. The protective box 2 has two rotating slots 4 inside. Two first motors 5 are mounted on the upper surface of the protective box 2. The output end of each first motor 5 passes through the protective box 2 and is rotatably connected to a first guide plate 6 via a round rod. A rotating shaft 7 is fixedly connected inside each first guide plate 6. A second guide plate 8 is rotatably connected to the outer surface of each rotating shaft 7. Connecting blocks 9 are installed on the opposite sides of the two second guide plates 8. A round hole 10 is opened on the outer surface of each connecting block 9. Electric push rods 11 are installed on the opposite sides of the protective box 2. The output end of each electric push rod 11 passes through the protective box 2 and is connected to a movable ball 12. The outer surface of each movable ball 12 is rotatably connected to the inner wall of the round hole 10. like Figure 1 , Figure 2 and Figure 3 As shown, a controller 3 is installed on the front of the protective box 2, and a second motor 13 is installed on the back of the protective box 2. The output end of the second motor 13 passes through the protective box 2 and is connected to a rotating rod 14. A first transmission roller 15 is fixedly connected to the outer surface of the rotating rod 14. A second transmission roller 16 and a third transmission roller 17 are rotatably connected inside the protective box 2. A conveyor belt 19 is connected to the outer surfaces of the first transmission roller 15, the second transmission roller 16, and the third transmission roller 17. When the controller 3 starts the second motor 13, its output end drives the rotating rod 14 and the first transmission roller 15 to rotate. Through the cooperation of the conveyor belt 19, the second transmission roller 16, and the third transmission roller 17, the material to be processed is transported to the subsequent device. Two support plates 18 are fixedly connected inside the protective box 2. The support plates 18 support the conveyor belt 19 to ensure... The conveying is smooth. An inclined plate 20 is fixedly connected inside the protective box 2. The material, which is positioned in the center, is conveyed to the inclined plate 20 by the conveyor belt 19. It slides onto the metal mesh 24 inside the shot blasting box 26 through the inclined plate 20. A third motor 21 is installed on the back of the protective box 2. The output end of the third motor 21 passes through the protective box 2 and is connected to the first transmission cylinder 22. A second transmission cylinder 23 is rotatably connected inside the protective box 2. The outer surfaces of the first transmission cylinder 22 and the second transmission cylinder 23 are connected to the metal mesh 24 through a common transmission. At this time, the third motor 21 starts and drives the first transmission cylinder 22 to rotate. Through the cooperation of the metal mesh 24 and the second transmission cylinder 23, the material is smoothly conveyed to the working range of the shot blasting module 28. A collection box 25 is set below the metal mesh 24. Waste shot, oxide scale and other impurities generated during the shot blasting process fall into the collection box 25 below through the mesh of the metal mesh 24.

[0018] like Figure 2As shown, a shot blasting box 26 is connected to the upper surface of the protective box 2. Protective curtains 27 are fixedly connected to the two sides of the shot blasting box 26 that are far apart from each other. The protective curtains 27 can block the shot from splashing and ensure that the material can enter and exit smoothly. Multiple shot blasting modules 28 are installed inside the shot blasting box 26 and inside the protective box 2. An injection pipe 29 is connected to the outer surface of each shot blasting module 28. The end of each injection pipe 29 away from the shot blasting module 28 passes through the protective box 2 and extends to the outside of the protective box 2. The end of each injection pipe 29 away from the shot blasting module 28 passes through the shot blasting box 26 and extends to the outside of the shot blasting box 26. The shot blasting module 28 receives the shot through the injection pipe 29 and, under the control of the controller 3, throws high-speed shot at the material surface from multiple angles to achieve the functions of sand removal, core removal, surface cleaning and strengthening.

[0019] like Figure 3 As shown, the inner top wall of the shot blasting box 26 is connected to two suction nozzles 30, and the upper surface of the shot blasting box 26 is connected to a waste bin 31. The outer surface of the waste bin 31 is equipped with two pump bodies 32. The output end of each pump body 32 is connected to a transmission pipe 33. The end of each transmission pipe 33 away from the pump body 32 passes through the shot blasting box 26 and connects to the upper surface of the suction nozzle 30. The input end of each pump body 32 passes through the waste bin 31 and extends into the interior of the waste bin 31. After the pump body 32 is started, it adsorbs the dust and fine impurities in the shot blasting box 26 through the suction nozzles 30 and sends them into the waste bin 31 for centralized collection through the transmission pipe 33, so as to avoid the accumulation of impurities affecting the shot blasting accuracy or polluting the environment.

[0020] The working principle of this utility model is as follows: When the material enters the protective box 2, the controller 3 drives the first motor 5 to rotate the round rod, which in turn drives the first guide plate 6 to adjust the angle with the rotation axis 7 as the fulcrum. At the same time, the controller 3 drives the electric push rod 11 to extend and retract, and the movable ball 12 rotates in the round hole 10 of the connecting block 9, pushing the second guide plate 8 to finely adjust its posture. The two sets of first guide plates 6 and second guide plates 8 form a symmetrical guiding structure, pushing the material that is off-center to the center line position of the conveyor belt 19, providing precise positioning for subsequent shot blasting.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
