Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a top sealing device for a hook-type shot blasting machine. Background Technology

[0002] Shot blasting machines use a high-speed rotating impeller to propel shot onto continuously tumbling workpieces inside a drum, thus cleaning the workpieces. They are suitable for cleaning sand, removing rust, removing oxide scale, and surface strengthening of castings and forgings weighing less than 15 kg in various industries.

[0003] A search revealed Chinese Patent Publication No. CN216542793U, which discloses a top sealing device for a hook-type shot blasting machine, comprising a cleaning chamber, a shielding assembly, and a support assembly. The support assembly includes a mounting base and a baffle. The shielding assembly includes a sliding plate, a control cylinder, and a rotating rod. The rotating rod is rotatably connected to the mounting base. The sliding plate has a groove and is slidably connected to the mounting base and rotatably connected to the rotating rod. The output end of the control cylinder is fixedly connected to the sliding plate. Shot blasting is performed in a cleaning chamber. The workpiece to be cleaned is hoisted into the cleaning chamber using a hook. Then, a control cylinder is activated to drive a sliding plate to slide relative to the mounting base. This causes the sliding plate and the baffle to cooperate in sealing the opening of the cleaning chamber, thus preventing steel shot from flying out of the cleaning chamber and avoiding subsequent cleaning of the steel shot, making it more convenient to use. The rotating rod can reduce the friction of the sliding plate movement, making sliding easier. Although this application can prevent steel shot from flying out during the cleaning process and thus avoid safety hazards, effectively reduce the daily cleaning workload of workers, reduce labor intensity, avoid resource waste, and increase the safety of using the hook-type shot blasting machine, the solution adopted in this application will not only lead to greater wear and tear during long-term use, but also require frequent replacement of parts, resulting in greater costs.

Both sides of the outer surface of the first sealing seat 21 are equipped with plug-in seats 23, and both sides of the outer surface of the second sealing seat 26 are provided with plug-in grooves 28. The top and bottom of the plug-in grooves 28 are equipped with spring limit blocks 29. The telescopic rod 273 is driven to extend and retract in the sleeve 272 by the drive device 27, thereby pushing the first sealing seat 21 and the second sealing seat 26 together to seal the limit groove 16. The sealing gaskets 22 on the first sealing seat 21 and the second sealing seat 26 can further improve the sealing performance. When the grooves 24 on the first sealing seat 21 and the second sealing seat 26 fix the hook, the protective gaskets 25 inside the grooves 24 can effectively reduce friction and prevent the hook from breaking due to long-term wear, thereby reducing costs.

[0025] In this embodiment, as Figure 1 As shown, the cleaning box structure 1 consists of a cleaning box body 11 and a power supply base 17. Box doors 12 are installed on both sides of the outer side of the cleaning box body 11. A limiting groove 16 is opened on the top of the outer surface of the cleaning box body 11. A spring plate 14 is installed inside the limiting groove 16. Two sliding grooves 15 are opened on both sides of the top of the cleaning box body 11 located at the limiting groove 16. The power supply base 17 is fixedly installed at the bottom of one side wall of the cleaning box body 11. The power supply base 17 provides power to the sealing structure 2. The first sealing seat 21 and the second sealing seat 26 are both fixed in the sliding groove 15 to prevent the positions of the first sealing seat 21 and the second sealing seat 26 from shifting.

[0026] As a preferred embodiment of the above, the output end of the drive device 27 is connected to the telescopic rod 273 in a transmission connection, and one end of the telescopic rod 273 is inserted into the inside of the sleeve 272, and the other end is connected to the first sealing seat 21 and the second sealing seat 26 respectively. The drive device 27 can drive the telescopic rod 273 to extend and retract in the sleeve 272, thereby pushing the first sealing seat 21 and the second sealing seat 26 together.

[0027] As a preferred embodiment of the above, the first sealing seat 21 and the second sealing seat 26 are respectively inserted into the sliding grooves 15 on both sides of the top of the cleaning box body 11, which can prevent the first sealing seat 21 and the second sealing seat 26 from shifting their positions when moving.

[0028] As a preferred embodiment of the above, the plug-in seat 23 has an arc-shaped structure, and notches are provided on the top and bottom of the plug-in seat 23 to cooperate with the spring limiting block 29.

[0029] As a preferred embodiment, the limiting groove 16 at the center of the top of the cleaning box body 11 is a circular structure. The grooves 24 on the first sealing seat 21 and the second sealing seat 26 can be joined together, and the joined grooves 24 are located directly above the circular structure of the limiting groove 16. The protective pad 25 inside the groove 24 can effectively reduce friction and prevent the hook from breaking due to long-term wear.

[0030] As a preferred embodiment, the outer side of the cabinet door 12 is equipped with a manual handle 13 that facilitates the operator to manually open the cabinet door 12. When the cabinet door 12 malfunctions and cannot be opened, it can be opened by the manual handle 13, thereby facilitating maintenance.

[0031] Working principle: Power is supplied to the sealing structure 2 through the power supply base 17. The drive device 27 drives the telescopic rod 273 to extend and retract in the sleeve 272, thereby pushing the first sealing seat 21 and the second sealing seat 26 together. The first sealing seat 21 and the second sealing seat 26 are inserted into the insertion slot 28 through the insertion seat 23, thereby firmly fixing the first sealing seat 21 and the second sealing seat 26 together and sealing the limiting groove 16. The sealing gasket 22 on the first sealing seat 21 and the second sealing seat 26 can further improve the sealing performance. When the groove 24 on the first sealing seat 21 and the second sealing seat 26 fixes the hook, the protective gasket 25 inside the groove 24 can effectively reduce friction and prevent the hook from breaking due to long-term wear, thereby reducing costs. When the box door 12 fails to open, it can be opened by the manual handle 13, which facilitates maintenance. This device has a simple structure, is easy to use, and has a lower cost.
