Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a hanging hook shot blasting machine. Background Art

[0002] The hook shot blasting machine is a crucial surface treatment device in industrial production. Its operating principle is based on the powerful centrifugal force generated by a high-speed rotating impeller, which propels the projectiles at extremely high speeds toward the surface of a workpiece suspended from the hook. At the moment of impact, impurities such as scale, rust, and old coatings are forcefully removed from the workpiece surface. Simultaneously, the impact of the projectile creates beneficial residual compressive stress on the workpiece surface, achieving a surface strengthening effect.

[0003] The patent discloses a single-hook shot blasting machine with the publication number CN219170613U. The patent sets a filter screen, a filter box, a drive motor and a cam. When the projectile falls, the filter box can filter impurities larger than the diameter of the projectile. When the drive motor is running, the cam will rotate through the rotating shaft. The rotation of the cam will cause the filter box to move upward and reciprocating, thereby enabling vibration screening. After that, the filter screen can filter impurities smaller than the diameter of the projectile, causing them to fall downward into the interior of the collection box, thereby enabling preliminary filtration of impurities such as rust, facilitating subsequent cleaning of the projectile.

[0004] However, after many existing hook-type shot blasting machines have finished cleaning the workpiece, when the shape of the workpiece is irregular or the hanging position on the hook causes the projectile to hit the workpiece and rebound toward the sealing door, the projectile is likely to adhere to the sealing door. When the sealing door is opened, the projectile on the sealing door will fall off and cannot enter the shot recovery system normally, resulting in waste of shot. If the projectile on the sealing door does not fall off, manual cleaning is required, which reduces production efficiency and increases production costs. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-5 The utility model provides a technical solution: a hanging hook shot blasting cleaning machine, a shot blasting machine body 1, two sealing doors 19 are provided on the outside of the shot blasting machine body 1, and scraping components are provided on the inside of the two sealing doors 19;

[0031] There are two groups of scraper assemblies, each group of scraper assemblies includes a connecting rod 23, one end of the connecting rod 23 is connected to the scraper 17 through a rotating shaft, and one end of the connecting rod 23 is provided with a second motor 22. The output end of the second motor 22 is fixedly connected to the rotating shaft inside the scraper 17, and the scraper 17 is located on one side of the sealing door 19.

[0032] When the shot blasting operation is completed, a small amount of projectiles will be attached to the sealing door 19. When the scraper 17 is not working, it is in a vertical state to prevent the projectiles from accumulating on the scraper 17. When the shot blasting operation is completed, the scraper assembly is started, and the second motor 22 runs. Its output end drives the scraper 17 to rotate around the rotating shaft, and the angle of the scraper 17 is adjusted to contact with the sealing door 19, so that it can fit well with the surface of the sealing door 19 to effectively scrape off the projectiles.

[0033] The electric track 15 is activated, and the moving block 16 slides on the electric track 15. Since the moving block 16 is fixedly connected to the connecting rod 23, the connecting rod 23 moves along with the moving block 16. In this way, the scraper 17 can move up and down on the surface of the sealing door 19 under the control of the electric track 15, thereby scraping off the projectiles on the entire surface of the sealing door 19.

[0034] The scraping operation of the scraper 17 allows the scraped pellets to be smoothly returned to the pellet recovery system via the receiving plate 18, thus avoiding pellet waste. The scraper 17 is driven by the second motor 22 and the electric track 15 to perform the scraping operation, thus achieving automated cleaning. Frequent manual cleaning of the sealing door 19 is no longer required, significantly reducing the difficulty and time of cleaning work, improving work efficiency, and minimizing disruption to the normal production process.

[0035] See also Figures 3-5 Each scraper assembly also includes an electric track 15, and the two electric tracks 15 are respectively fixedly connected to the inner wall of the shot blasting machine body 1. One end of the electric track 15 is slidably connected to a moving block 16, and one end of the moving block 16 is fixedly connected to the connecting rod 23. A receiving plate 18 is provided on the inside of the shot blasting machine body 1. The receiving plate 18 is located at the bottom end of the two sealing doors 19, and the receiving plate 18 is inclined.

[0036] The scraped shots fall onto the receiving plate 18 at the bottom of the sealing door 19. The receiving plate 18 is tilted, and the shots roll along the inclined surface of the receiving plate 18 under the action of gravity, and eventually roll to the bottom of the shot blasting machine body 1, and are transported to the outside by the spiral conveyor roller 20 for recovery and other operations.

[0037] See also Figures 1-3 A slide rail 2 is provided above the shot blasting machine body 1, and a slider 4 is slidably connected to one end of the slide rail 2. An electric hoist 3 is fixedly connected to the bottom of the slider 4. A steel rope 5 is provided inside the electric hoist 3. A pulley 6 is provided below the electric hoist 3. The steel rope 5 is sleeved on the outer wall of the pulley 6. A first motor 12 is provided at the bottom of the pulley 6. The output end of the first motor 12 is connected to a hook 7 through a rotating shaft. The bottom of the shot blasting machine body 1 is funnel-shaped, and a discharge pipe 21 is provided at the bottom end of the shot blasting machine body 1. A spiral conveying roller 20 is provided inside the shot blasting machine body 1 and the discharge pipe 21.

[0038] When the workpiece needs to be put into the shot blasting machine body 1 for shot blasting cleaning, the sealing door 19 is opened, and the electric hoist 3 is moved to the appropriate position on the slide rail 2 through the sliding block 4. Then, the electric hoist 3 lowers the steel rope 5, and the hook 7 connected after the steel rope 5 passes through the pulley 6 is lowered, and the workpiece is hung on the hook 7. After that, the electric hoist 3 lifts the workpiece up through the steel rope 5, and then moves the workpiece to the top of the shot blasting machine body 1 through the movement of the sliding block 4 on the slide rail 2, and prepares to put the workpiece into the shot blasting machine body 1 for cleaning. During the shot blasting process, the first motor 12 works, and its output shaft drives the hook 7 to rotate through the rotating shaft. Since the workpiece is hung on the hook 7, the workpiece will rotate with the hook 7, so that each surface of the workpiece can uniformly receive shot blasting treatment, ensuring the consistency of the cleaning effect. After the shot blasting is finished, the shot will fall at the bottom of the shot blasting machine body 1. Since the bottom of the shot blasting machine body 1 is funnel-shaped, the shot will gather at the center of the bottom under the action of gravity. Then, through the discharge pipe 21 connected at the bottom end of the shot blasting machine body 1, under the action of the discharge pipe 21 and the spiral conveying roller 20 inside the shot blasting machine body 1, the spiral conveying roller 20 rotates to push the shot to move along the discharge pipe 21, and the shot is conveyed to the corresponding position of the shot recycling system for recycling, screening and recycling.

[0039] Please refer to Figures 1-3 , two shot blasting machines 10 are arranged at the two ends of the shot blasting machine body 1, a shot storage bin 8 is arranged at one side of the shot blasting machine body 1, a first pneumatic conveying device 9 is arranged at the top of the shot storage bin 8, one end of the first pneumatic conveying device 9 is provided with a second pneumatic conveying device 11, the second pneumatic conveying device 11 and the shot storage bin 8 are connected through a pipe body, a transfer bin 14 is arranged at the rear side of the shot blasting machine body 1, the transfer bin 14 and the second pneumatic conveying device 11 are connected through a pipe body, and two material conveying pipes 13 are arranged at the two ends of the transfer bin 14 and are in communication, and one end of each of the two material conveying pipes 13 is in communication with a corresponding shot blasting machine 10.

[0040] After the shot in the shot storage bin 8 is sucked out by the second pneumatic conveying device 11 and transported to the transfer bin 14 through the pipe body, the shot enters the two shot blasting machines 10 from the two material conveying pipes 13 at the two ends of the transfer bin 14. In this process, the pneumatic conveying device uses the air flow generated by compressed air as power to push the shot to flow in the pipeline system, realizing the conveying of the shot from the shot storage bin 8 to the shot blasting machine 10.

[0041] When the shot in the shot storage bin 8 is not much, the first pneumatic conveying device 9 is connected with external pipeline equipment to add external shot into the shot storage bin 8, and the first pneumatic conveying device 9 is in a closed state when not in use.

[0042] Working principle: first, when the workpiece needs to be cleaned by shot blasting, the sealing door 19 is opened, and the electric hoist 3 located above the shot blasting machine body 1 starts to work. After the electric hoist 3 moves to the appropriate position on the slide rail 2 by means of the sliding block 4, it lowers the steel wire 5, which drives the hook 7 to lower through the pulley 6, and hangs the workpiece on the hook 7, then the electric hoist 3 lifts the workpiece and moves to the top of the shot blasting machine body 1, prepares to put the workpiece into, after putting in, close the sealing door 19.

[0043] In the process of shot blasting, the first motor 12 drives the hook 7 to rotate, so that the workpiece hung on the hook 7 rotates with it, ensuring that each surface of the workpiece uniformly receives shot blasting treatment. At the same time, the shot in the shot storage bin 8 is transported to the transfer bin 14 through the first pneumatic conveying device 9 at the top and the second pneumatic conveying device 11 connected thereto, and then enters the two shot blasting machines 10 through the material conveying pipes 13 at both ends of the transfer bin 14, and the shot blasting machines 10 accelerate the shot to the surface of the workpiece.

[0044] After the shot blasting is finished, the shot is scattered at the bottom of the shot blasting machine body 1, because the bottom is funnel-shaped, the shot is collected to the center under the action of gravity, and then transported to the shot recycling system by the spiral conveying roller 20 in the discharge pipe 21. At this time, the scraping assembly starts, the second motor 22 drives the scraper 17 to rotate to fit with the sealing door 19, then the electric track 15 makes the moving block 16 drive the connecting rod 23 and the scraper 17 move up and down on the surface of the sealing door 19, the scraped shot is rolled to the bottom of the shot blasting machine body 1 through the material receiving plate 18, and finally transported and recycled by the spiral conveying roller 20. When the shot in the shot storage bin 8 is insufficient, the first pneumatic conveying device 9 can be connected to the external pipeline equipment to supplement the shot, and the device is in closed state when not in use. The whole process is efficient and orderly, realizes a series of operations such as workpiece shot blasting cleaning, shot recycling and supplementing, and guarantees the stable operation and continuous operation ability of the equipment.
