Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting machine. Background Technology
[0002] Shot blasting machines are equipment used for metal surface treatment. They mainly use a high-speed rotating impeller to throw abrasive particles onto the surface of the workpiece to achieve the purpose of rust removal, oxide scale removal and surface strengthening. Shot blasting machines are suitable for surface treatment of various metal and non-metal materials, such as carbon steel and alloy steel, and are widely used in surface sandblasting treatment of automotive parts, motorcycle parts, machine tool parts, etc.
[0003] Currently, in the process of shot blasting metal parts, abrasive particles are propelled towards the metal parts by a high-speed rotating impeller. These particles can be reused via a material lifting mechanism. However, during this process, the abrasive particles collide with the metal parts, causing damage to the particles. The damaged particles develop sharp edges, which, when reused, can impact the metal surface, resulting in dents and scratches, thus affecting the quality of the metal parts. Therefore, we propose a shot blasting machine. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. Example
[0029] Please see Figures 1-9 A shot blasting machine includes a body 1, a shot blasting machine 2 mounted on the top of the body 1, a fixed cover 3 fixedly connected to the back of the body 1, a material cover 4 connected to one side of the fixed cover 3, and a connecting pipe 5 connected to the shot blasting machine 2 at the bottom of the material cover 4; it also includes: a screening component 7, installed inside the body 1 and located at the bottom of the metal parts processing chamber, the screening component 7 being used to screen the abrasive particles used after blasting; and a material lifting component 6, installed inside the fixed cover 3, the material lifting component 6 being used to transport the screened qualified abrasive particles into the material cover 4, and then to the shot blasting machine 2 through the connecting pipe 5.
[0030] Please see Figures 2-4 The screening component 7 shown in the figure includes a receiving hopper 8 installed inside the machine body 1. The bottom end of the receiving hopper 8 is inclined and faces the material lifting component 6. The bottom end of the receiving hopper 8 is connected to a discharge hopper 9. The bottom end of the discharge hopper 9 has several sets of screen holes 10. An inclined guide plate 11 is installed between the receiving hopper 8 and the discharge hopper 9. The discharge hopper 9 has a discharge port 12 at the end of the material lifting component 6. The discharge port 12 is connected to the fixed cover 3. A striking element 13 is provided on the outside of the discharge hopper 9 to facilitate the screening of used abrasive particles.
[0031] Please see Figure 2 , Figure 5 and Figure 6The striking element 13 shown in the figure includes multiple sets of striking heads 15 installed on one side of the hopper 9. A striking rod 16 is fixedly connected to each striking head 15. A connecting plate 17 is fixedly connected between the multiple sets of striking rods 16. A rack 18 is fixedly connected to the connecting plate 17. An elastic connecting member 19 is installed at the end of the rack 18. A moving member 20 for driving the rack 18 to move is connected to the outside of the rack 18, which facilitates striking the hopper 9 and improves the screening efficiency of abrasive particles.
[0032] Please see Figure 5 and Figure 6 The elastic connector 19 shown in the figure includes a fixing rod 21 fixed inside the body 1. The fixing rod 21 is slidably connected to the rack 18, and a fixing plate 22 is fixedly connected to the fixing rod 21. A spring 23 is fixedly connected to the fixing plate 22. A connecting piece 24 fixedly connected to the rack 18 is fixedly connected to the end of the spring 23 to facilitate the reset of the rack 18.
[0033] Please see Figure 5 and Figure 7 The movable component 20 shown in the figure includes a motor 25 fixedly connected to the fixed cover 3. The output end of the motor 25 is fixedly connected to a drive shaft 26. The drive shaft 26 passes through the fixed cover 3 and the machine body 1 and is rotatably connected to the fixed cover 3 and the machine body 1. A transmission component 27 is connected to the drive shaft 26. An incomplete gear 28 that meshes with the rack 18 is installed on the transmission component 27 to facilitate the reciprocating movement of the rack 18.
[0034] Please see Figure 5 and Figure 7 The transmission component 27 shown in the figure includes a drive wheel 29 fixedly connected to the drive shaft 26. A belt 30 is drivenly connected to the outer side of the drive wheel 29. A driven wheel 31 is drivenly connected to the belt 30. A transmission shaft 32 fixedly connected to the incomplete gear 28 is fixedly connected to the axis of the driven wheel 31. The transmission shaft 32 is rotatably connected to the machine body 1 to facilitate power transmission.
[0035] Please see Figure 8 and Figure 9 The material lifting assembly 6 shown in the figure includes two sets of rotating rollers 33 rotatably installed inside the fixed cover 3. The outer sides of the two sets of rotating rollers 33 are connected to a conveyor belt 34. Multiple sets of material plates 35 are fixedly connected to the conveyor belt 34, and the rotating rollers 33 located at the bottom are fixedly connected to the drive shaft 26, so as to facilitate the conveying of qualified abrasive particles after screening to the shot blasting machine 2 for reuse.
[0036] Please see Figure 2The bottom of the feeding hopper 9 shown in the figure is equipped with a receiving tray 14 fixed inside the machine body 1. The end of the receiving tray 14 extends to the outside of the machine body 1, which facilitates the conveying of unqualified abrasive particles after screening to the outside of the machine body 1 for processing.
[0037] During the implementation process, when the machine body 1 processes the metal parts, the shot blasting machine 2 throws abrasive particles onto the metal. After processing the metal, the abrasive particles will fall into the receiving hopper 8. At this time, the abrasive particles are guided into the discharge hopper 9 by the guide plate 11. The discharge hopper 9 has a screen hole 10. Damaged abrasive particles will fall into the receiving tray 14 through the screen hole 10. The receiving tray 14 will then discharge the damaged abrasive particles for centralized processing. During this process, qualified abrasive particles will enter the fixed cover 3 through the discharge port 12. At this time, the motor 25 is started, and the drive shaft 26 is rotated by the motor 25. This causes the rotating roller 33 to rotate, which in turn drives the conveyor belt 34 to rotate. The rotation of the conveyor belt 34 drives the material plate 35 to rotate. The material plate 35 transports the abrasive particles to the end position of the fixed cover 3. Then, the centrifugal force of the rotation discharges the abrasive particles into the material cover 4. Finally, the abrasive particles are transported to the shot blasting machine 2 for reuse through the connecting pipe 5.
[0038] During the startup of motor 25, drive shaft 26 drives drive wheel 29 to rotate. The rotation of drive wheel 29 drives driven wheel 31 to rotate via belt 30, which in turn drives drive shaft 32 to rotate. Drive shaft 32 causes incomplete gear 28 to rotate. When incomplete gear 28 rotates, it drives rack 18 to move. During the movement of rack 18, it compresses spring 23. After incomplete gear 28 disengages from rack 18, spring 23 resets, causing rack 18 to reset. This causes connecting plate 17 to drive knocking rod 16 and knocking head 15 to reset. Knocking head 15 then knocks the feed hopper 9, improving the screening efficiency of abrasive particles and preventing clogging of screen holes 10.
