Description

Technical Field

[0001] This utility model belongs to the field of metal polishing technology, specifically relating to a roller basket for a drum-type sandblasting machine. Background Technology

[0002] The drum-type sandblasting machine, also known as the basket-type sandblasting machine, has a core structure consisting of an automatically rotating drum inside a sealed box. A fixed spray gun is used to sandblast the workpiece inside the drum. It is mainly suitable for surface treatment of small batches of precision parts, including burr removal and matte finishing of materials such as metal fasteners, aluminum and copper products, and plastic parts. It also has the industrial characteristics of automation and flexible modification.

[0003] For example, prior art with publication number CN201711855U discloses an inclined octagonal olive-shaped barrel polishing machine. It includes a frame, on which an inclined barrel is mounted, and the barrel is connected to a motor mounted on the frame via a belt reducer. This utility model has a simple structure and low manufacturing cost. The octagonal olive-shaped drum of this utility model is a conical drum, and it is set at an incline. Therefore, during operation, the workpiece has a large tumbling force inside the drum, and the impact friction between the workpiece and the abrasive is large, resulting in a high friction probability and good polishing effect. However, in practical applications, the drum used to hold parts in a drum-type sandblasting machine will wear down due to the long-term rolling, collision, and friction of the parts or the impact of the steel sand sprayed from the spray gun. That is to say, the inner wall of the drum will gradually wear down, especially the bottom of the drum. Since the main working part is the bottom of the drum when the parts are tumbling with the rotation of the drum, the entire drum needs to be disassembled when replacing or maintaining the drum. However, the damaged part of the drum is concentrated at the bottom of the drum or in a certain local area. Therefore, replacing the entire drum will also require replacing the rest of the drum, resulting in the waste of the rest of the drum when it is not used, which will increase the cost of replacing the drum. Summary of the Invention

[0004] Based on this, this application provides a roller basket for a drum-type sandblasting machine to solve the technical problem in the prior art that replacing the drum when it is partially damaged leads to waste of the remaining parts and increased production costs.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please refer to Figures 1 to 7 In one specific embodiment of this application,

[0034] A drum-type sandblasting machine basket includes:

[0035] Base cover assembly;

[0036] An upper cover assembly is disposed on the lower cover assembly and is used to cooperate with the lower cover assembly to form a roller. The upper cover assembly and the lower cover assembly are detachably connected.

[0037] The quick-release assembly includes both the upper cover assembly and the bottom cover assembly, which are embedded within it.

[0038] A transmission assembly, wherein the quick-connect assembly is disposed on the transmission assembly and is used to be connected to a power source and driven to rotate by the power source.

[0039] The bottom cover assembly can be a cylinder or a plane; the upper cover assembly can be a tube; the quick-release assembly can be a clamp or a device that can hold the upper cover assembly; the transmission assembly can be a coupling or a gear ring or other transmission device; the detachable connection between the bottom cover assembly and the upper cover assembly can be a bolt connection.

[0040] In practical applications, the transmission component is connected to the power source, which is the power input device set in the drum-type sandblasting machine itself. The output shaft of the geared motor is connected to the transmission component, and then the quick-connect component is connected to the transmission component. After the upper cover component and the bottom cover component are connected together to form a drum, they are clamped in the quick-connect component. Finally, the parts are put into the drum. Driven by the power source, the transmission component and the quick-connect component are rotated. The quick-connect component drives the drum to rotate, and then the spray gun sprays steel sand into the parts inside the drum. Sandblasting can be performed while the parts are tumbling.

[0041] The above method allows for targeted replacement of the roller when localized wear occurs after prolonged use, eliminating the need to replace the entire roller and reducing manufacturing or procurement costs. For example, when the roller is upright, the parts primarily impact and rub against the steel shot at the bottom (the bottom cover assembly mentioned above). Therefore, replacement only requires disassembling the top and bottom cover assemblies, replacing the bottom cover assembly, and then connecting the top cover assembly to the new bottom cover assembly for continued use, avoiding waste caused by replacing the top cover assembly while it is still usable. Similarly, when the roller is horizontal, the parts primarily impact and rub against the steel shot at the top cover assembly, requiring only the replacement of the top cover assembly, eliminating the need to replace the bottom cover assembly and reducing replacement costs. Furthermore, compared to traditional drum-type sandblasting machines, quick-connect components allow for rapid disconnection of the roller from the power source. In traditional designs, the roller is directly connected to the power source (gear motor) through welding or bolting, making roller disassembly difficult, complex, and time-consuming.

[0042] If the connection between the upper cover assembly and the lower cover assembly is made by bolts, then the bolts need to be tightened during disassembly or installation. This is not only time-consuming and laborious, but also may cause the bolts to strip and become damaged.

[0043] Therefore, this application also includes a quick-release part, through which the upper cover assembly and the bottom cover assembly are installed and removed.

[0044] The quick-release mechanism can be a latch or a snap-fit, which allows for rapid connection and disconnection. In practical use, this feature can be used to quickly connect and disconnect the upper cover assembly and the lower cover assembly, thereby shortening the time required for connection and installation of the upper cover assembly and the lower cover assembly, saving time and improving efficiency.

[0045] Specifically, an embodiment of the quick-release mechanism in the above process is provided:

[0046] The quick-release part includes a side panel latch A201 and a hook A202 that engages with and locks the side panel latch A201. Of the side panel latch A201 and the hook A202, one is connected to the bottom cover assembly and the other is disposed on the upper cover assembly.

[0047] By connecting the panel lock A201 to the bottom cover assembly and the hook A202 to the top cover assembly, the panel lock A201 can be used to hook the hook A202 to lock the top cover assembly when it is being installed on the bottom cover assembly, thus connecting the top cover assembly and the bottom cover assembly. This method enables quick connection and disassembly between the top cover assembly and the bottom cover assembly, improving the efficiency of connection and disassembly, and is faster and more convenient than bolt connection.

[0048] Specifically, an embodiment of the bottom cover assembly in the above process is provided:

[0049] The bottom cover assembly includes a bottom basket 101, with a plurality of sieve holes evenly distributed on the side wall of the bottom basket 101. The upper cover assembly is disposed on the upper end of the bottom basket 101, and the panel lock A201 or the hook A202 is connected to the outer wall of the bottom basket 101.

[0050] The sieve holes distributed on the side wall of the bottom basket 101 allow the steel sand and impurities removed from the parts to leak out after the steel sand is sprayed out by the spray gun to polish the parts, so that the parts can be kept in the bottom basket 101, thus separating the parts from the impurities and steel sand. In addition, the panel lock A201 or the hook A202 can be fixed to the outer wall of the bottom basket 101. If the panel lock A201 is fixed to the outer wall of the bottom basket 101, then the hook A202 is fixed to the upper cover assembly, thereby realizing the connection between the bottom basket 101 and the upper cover assembly.

[0051] Specifically, an embodiment of the bottom cover assembly in the above process is provided:

[0052] The upper cover assembly includes a top cover 102 with an open top end. Several sieve holes are evenly distributed on the side wall of the top cover 102. The lower end of the top cover 102 is located on the upper end of the bottom basket 101. The railing buckle A201 or the hook A202 is connected to the outer wall of the top cover 102.

[0053] For example, if the panel latch A201 is fixed to the outer wall of the top cover 102, then the hook A202 is connected to the bottom basket 101. When connecting, the top cover 102 is placed on the top of the bottom basket 101 and the panel latch A201 and the hook A202 are aligned vertically. Then the panel latch A201 and the hook A202 are connected together, which can achieve a quick connection between the top cover 102 and the bottom basket 101. Conversely, it can be quickly disassembled when it is necessary to replace part of the top cover 102 and the bottom basket 101.

[0054] Additionally, a handle 103 is formed on the upper outer wall of the top cover 102 to facilitate the movement of the entire roller by the operator.

[0055] Specifically, an embodiment of the bottom cover assembly in the above process is provided:

[0056] The quick-assembly assembly includes a base frame 401, with a limiting ring 402 formed at the upper end of the base frame 401, a bottom basket 101 embedded in the base frame 401, and a top cover 102 embedded in the limiting ring 402.

[0057] In use, after connecting the top cover 102 and the bottom basket 101 together to form a roller, the entire roller is directly embedded into the base frame 401. Thus, when the quick-release assembly is driven to rotate by the transmission group, the base frame 401 can drive the roller to rotate. The limiting ring 402 can extend the clamping and limiting capacity of the roller in the height direction, so that the roller is embedded into the base frame 401 to a greater depth, and the roller will not fall out when it rotates with the base frame 401.

[0058] Since the limiting ring 402 is a complete ring, in order to ensure that the roller is embedded in the base frame 401, the limiting ring 402 and the outer wall of the roller need to be fitted with a clearance. That is to say, there is a gap between the outer wall of the roller and the limiting ring 402. Although the limiting ring 402 can enhance the limiting ability of the roller, the existence of the gap will cause the outer wall of the roller to hit the limiting ring 402 when the roller rotates with the base frame 401, and there will be noise caused by the roller shaking in the limiting ring 402.

[0059] Therefore, in this application, the limiting ring 402 has a break 403 in the middle, and the outer walls of the limiting ring 402 on both sides of the break 403 are detachably connected by a connecting part.

[0060] The limiting ring 402 is broken by the break 403, dividing it into two parts. These two parts are then connected by a connecting part, which is a connector that links the broken limiting ring 402 together, such as a bolt or clip. Both the limiting ring 402 and the base frame 401 can be made of elastic metal, meaning they can undergo elastic deformation. Normally, the inner circumference of the limiting ring 402 is smaller than the outer circumference of the top cover 102. Therefore, when installing the rollers, the bottom basket 101 moves outwards, pushing the limiting ring 402 apart. The two parts of 02 will have an increased break at this point. The two parts of the limiting ring 402 will contact the outer wall of the bottom basket 101 due to elastic deformation, and eventually contact the outer wall of the top cover 102 as the bottom basket 101 extends in. After the bottom basket 101 is embedded in the bottom frame 401, the two parts of the limiting ring 402 can be connected and tightened through the connecting part, so that the two parts of the limiting ring 402 clamp the outer wall of the top cover 102, thereby eliminating the gap between the outer wall of the top cover 102 and the limiting ring 402. This method is used to achieve the clamping and fixing of the top cover 102, so that the roller can be stably connected in the bottom basket 101.

[0061] Specifically, an embodiment is provided for the connecting part in the above process:

[0062] The connecting part includes a railing latch B301 and a hook B302 that cooperates with the railing latch B301 to lock together. The railing latch B301 and the hook B302 are respectively connected to the outer wall of the limiting ring 402 on both sides of the break 403.

[0063] After the roller is embedded into the base frame 401, it is connected to the hook B302 through the side panel lock B301. When the side panel lock B301 and the hook B302 are connected, the two parts of the limit ring 402 are tightened, and the two parts of the limit ring 402 clamp the roller.

[0064] Specifically, an embodiment of the transmission component in the above process is provided:

[0065] The transmission assembly includes a bushing 502, which is disposed at the lower end of the base frame 401 and is used to connect to the power source.

[0066] Taking a geared motor as a power source as an example: A geared motor is installed at the bottom of the casing of a drum-type sandblasting machine, and the output shaft of the geared motor extends into the casing. The bushing 502 can be directly connected to the output shaft of the geared motor through a coupling, so that the base frame 401 can be connected to the power source. Then, when the geared motor starts, the output shaft drives the bushing 502 to rotate, thereby causing the bushing 502 to drive the base frame 401 to rotate, which in turn drives the drum to rotate.

[0067] In addition, to facilitate the maintenance and replacement of the base frame 401, in this application, the lower end of the base frame 401 is formed with a sleeve 404, and the upper end of the bushing 502 is formed with a plug 501 that can be embedded in the sleeve 404. The plug 501 is provided with a threaded hole 503, and the sleeve 404 is provided with a locking bolt 405 that can pass through the inner wall of the sleeve 404 and connect to the threaded hole 503.

[0068] In other words, the insert 501 can be inserted into the sleeve 404, and then screwed into the threaded hole 503 by the locking bolt 405 to connect the insert 501 and the sleeve 404 together. In this way, the base frame 401 and the bushing 502 can be quickly disassembled and installed, which facilitates the replacement and maintenance of the base frame 401.

[0069] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
