Description

Technical Field

[0001] This utility model relates to the technical field of alloy surface processing, and in particular to a rotary alloy surface sandblasting treatment device. Background Technology

[0002] Wood fiber is a natural organic material. Wood fiber is a long and thin fiber that is easy to entangle and clump together. It requires strong stirring to break it up and mix it evenly. Therefore, a rotary alloy surface sandblasting treatment device is needed.

[0003] A device for omnidirectional sandblasting of zinc-aluminum alloys, authorized by announcement number CN221792326U, includes a worktable. Support frames are fixedly installed at the four corners of the worktable's outer surface. A nozzle is positioned above the center of the worktable. An adjustment mechanism is located in the center of the opposite side of each support frame. The adjustment mechanism includes a guide rod positioned above the opposite side of the right support frame. A lead screw is rotatably mounted on the left side of the guide rod, located above the opposite side of the left support frame, via a bearing. A drive motor is mounted on the rear end of the lead screw, passing through the support frame. Moving blocks are provided on the surfaces of both the lead screw and the guide rod, and these moving blocks are threadedly connected to the lead screw and slidably connected to the guide rod. A transverse mechanism is provided at the opposite end of each moving block. Compared to existing ordinary omnidirectional sandblasting devices for zinc-aluminum alloys, this device can drive the nozzle to adjust various points within the same plane, ensuring omnidirectional spraying of the same surface of the zinc-aluminum alloy.

[0004] However, the aforementioned all-around sandblasting device for zinc-aluminum alloys can only process one workpiece at a time, resulting in low efficiency and poor continuity. Furthermore, the nozzle can only move laterally for sandblasting and cannot be adjusted in height as needed.

[0005] To address the aforementioned issues, a rotary alloy surface sandblasting treatment device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a rotary alloy surface sandblasting treatment device to solve the problems of the existing rotary alloy surface sandblasting treatment devices mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotary alloy surface sandblasting treatment device, including a processing table, a rotating mechanism at the top of the processing table, a sandblasting mechanism at the other end of the top of the processing table, side plates fixedly arranged on both sides of the top of the processing table, and a crossbeam bolted to the top of the side plates;

[0008] The rotating mechanism includes a shaft mounted on the top of the processing table. A sleeve is fitted on the surface of the shaft, and the protrusion of the inner wall of the sleeve is adapted to the concave part of the shaft surface. An internally threaded tube is threaded to the surface of the shaft near the top. Four sets of U-shaped frames are welded to the outside of the sleeve with the center of the sleeve as the axis. Each U-shaped frame has a U-shaped groove on its inner side. Two sets of clamping bolts are threaded to the side of the U-shaped frame away from the sleeve.

[0010] Preferably, the top of the shaft is rotatably connected to the bottom wall of the crossbeam, and the bottom of the shaft is connected to the large gear.

[0011] Preferably, the sleeve is disposed between the internally threaded pipe and the protective cover, and the protective cover is disposed at the connection between the shaft and the large gear.

[0012] Preferably, both the large gear and the small gear are mounted on the top of the bottom beam, and the large gear is rotatably connected to the bottom beam.

[0013] Preferably, the sandblasting mechanism includes a movable plate slidably connected to one side wall of the processing table, an mounting plate welded to the top of the bottom beam, a first guide post passing through the bottom end of the movable plate and the first guide post being installed between the processing table and the mounting plate, the bottom end of the movable plate being connected to the output end of an electric actuator, and the other end of the electric actuator being installed on the mounting plate.

[0015] Preferably, the sandblasting mechanism is provided in two locations, located on both sides of the processing table, with the sandblasting gun facing both sides of the U-shaped frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This rotary alloy surface sandblasting treatment device is equipped with a rotating mechanism and four sets of U-shaped frames. During the processing, the four sets of U-shaped frames can rotate in sequence and take turns sending the workpieces fixed on them to the working range of the sandblasting gun. At the same time, multiple workpieces can be sandblasted, which greatly shortens the overall processing cycle and improves production efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] like Figure 1-3As shown, the machine includes a processing table 1, a rotating mechanism 2 at the top of the processing table 1, a sandblasting mechanism 3 at the other end of the top of the processing table 1, side plates 4 fixedly installed on both sides of the top of the processing table 1, and a crossbeam 5 bolted to the top of the side plates 4. The rotating mechanism 2 includes a shaft 201 installed on the top of the processing table 1, a sleeve 202 fitted on the surface of the shaft 201, and the protrusion of the inner wall of the sleeve 202 fitting with the concave part of the surface of the shaft 201. An internally threaded tube 203 is threadedly connected to the surface of the shaft 201 near the top. Four sets of U-shaped frames are welded to the outside of the sleeve 202 with the center of the sleeve 202 as the axis. 204. U-shaped grooves 205 are provided on the inner side of the U-shaped frame 204. Two sets of clamping bolts 206 are threadedly connected to the side of the U-shaped frame 204 away from the sleeve 202. The rotating mechanism 2 also includes a bottom beam 207 welded to the bottom of the processing table 1. A protective cover 208 is provided on the surface of the shaft column 201 near the bottom. An anti-slip pad 209 is glued to the side of the clamping bolt 206 near the sleeve 202. A first drive motor 210 is installed at the bottom of the bottom beam 207. A small gear 211 is installed on the top of the output end of the first drive motor 210. A large gear 212 is meshed at one end of the small gear 211.

[0028] It should be noted that in this embodiment, firstly, the alloy workpiece to be sandblasted is placed in the U-shaped groove 205 of the four sets of U-shaped frames 204. By rotating the tightening bolt 206, the anti-slip pad 209 on the side near the sleeve 202 contacts and abuts against the workpiece surface, thereby fixing the workpiece on the U-shaped frame 204. Then, the first drive motor 210 is started. The output end of the first drive motor 210 drives the pinion 211 to rotate. Since the pinion 211 meshes with the large gear 212, the rotation of the pinion 211 drives the large gear 212 to rotate. Since the bottom of the shaft 201 is connected to the large gear 212, the rotation of the large gear 212 drives the shaft 201 to rotate. Also, since the protrusion of the inner wall of the sleeve 202 matches the concave part of the surface of the shaft 201, the rotation of the shaft 201 will drive the sleeve 202 to rotate, thereby driving the four sets of U-shaped frames 204 sleeved on the outside of the sleeve 202 to rotate.

[0029] When maintenance is required, since the crossbeam 5 is bolted to the top of the side plate 4, the bolts are first unscrewed to open the crossbeam 5. Since the sleeve 202 is located between the internal threaded tube 203 and the protective cover 208, and the surface of the shaft column 201 is threadedly connected to the internal threaded tube 203 near the top, the internal threaded tube 203 is rotated and removed from the shaft column 201. The sleeve 202 is then removed to separate it from the shaft column 201. Subsequently, the sleeve 202 and the U-shaped frame 204 can be removed from the shaft column 201 together for easy cleaning and maintenance. The protective cover 208 is located at the connection between the shaft column 201 and the large gear 212 to prevent sand particles from entering the connection between the shaft column 201 and the large gear 212 during processing and affecting its transmission.

[0030] Furthermore, the bottom beam 207 is welded to the bottom of the processing table 1, and the first drive motor 210 is installed at the bottom of the bottom beam 207. At the same time, the large gear 212 and the small gear 211 are also installed on the top of the bottom beam, and the large gear 212 is rotatably connected to the bottom beam. The bottom beam 207 provides a mounting base for these components.

[0031] like Figure 4 , 5 As shown, the sandblasting mechanism 3 includes a movable plate 301 slidably connected to one side wall of the processing table 1, an mounting plate 302 welded to the top of the bottom beam 207, a first guide post 303 passing through the bottom end of the movable plate 301, and the first guide post 303 being installed between the processing table 1 and the mounting plate 302, the bottom end of the movable plate 301 being connected to the output end of the electric push rod 304, and the other end of the electric push rod 304 being installed on the mounting plate 302. The sandblasting mechanism 3 also includes a groove 305 opened at one end of the movable plate 301, a second drive motor 306 being installed on the top of the movable plate 301, a U-shaped plate 307 slidably connected to the inner wall of the groove 305, a threaded rod 308 threadedly connected to the inner wall of the U-shaped plate 307, a second guide post 309 passing through the inner wall of the U-shaped plate 307 and slidably connected to the second guide post 309, and a sandblasting gun 310 being installed on the side of the U-shaped plate 307 located outside the movable plate 301.

[0032] It should be noted that, in this embodiment, during sandblasting of the workpiece, if it is necessary to adjust the horizontal position of the sandblasting gun 310, the electric actuator 304 is activated. The output end of the electric actuator 304 pushes the movable plate 301, and the movable plate 301 slides horizontally along the first guide post 303, thereby driving the sandblasting gun 310 mounted on the movable plate 301 to move horizontally, facilitating the adjustment of the distance between the sandblasting gun 310 and the workpiece. When it is necessary to adjust the height position of the sandblasting gun 310, since the second guide post 309 is located between the top and bottom walls of the slide groove 305, the top of the threaded rod 308... The top of the movable plate 301 is connected to the output end of the second drive motor 306. The bottom of the threaded rod 308 is rotatably connected to the bottom wall of the movable plate 301. The inner wall of the U-shaped plate 307 is threadedly connected to the threaded rod 308. The inner wall of the U-shaped plate 307 is slidably connected to the second guide post 309. When the threaded rod 308 rotates, the U-shaped plate 307 slides up and down along the second guide post 309 in the slide groove 305. The sandblasting gun 310 installed on the outside of the U-shaped plate 307 moves up and down with the U-shaped plate 307 to adjust the height of the sandblasting gun 310 for easy and uniform sandblasting.

[0033] When the four sets of U-shaped frames 204 rotate to the appropriate position, the sandblasting guns 310 located on both sides of the processing table 1 start simultaneously to perform double-sided sandblasting on the workpieces fixed on the U-shaped frames 204. The four sets of U-shaped frames 204 rotate continuously, taking turns to send the workpieces on each U-shaped frame 204 to the working range of the sandblasting guns 310, so as to achieve continuous processing and effectively improve processing efficiency.

[0034] Furthermore, the mounting plate 302 is welded to the top of the bottom beam 207 and cooperates with the processing table 1, providing an installation position for the first guide column 303 and the electric push rod 304. The mounting plate 302 is located on both sides of the pinion 211 and the large gear 212, so as not to affect the movement of the two sets of gears.

[0035] Furthermore, in this rotary alloy surface sandblasting device, both the first drive motor 210 and the second drive motor 306 are motors with bidirectional rotation and self-locking functions. This type of motor technology has been widely used in related fields and is a mature existing technology. Its specific working principle and implementation process will not be described in detail here. Moreover, the air source and abrasive supply components connected to the external of the sandblasting gun 310 are mature existing technologies in the field of sandblasting equipment. Given that this part of the technology has been widely used in the industry and is well known to the public, it is not shown in the figure and will not be described in detail here.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figure 1-5 First, place the alloy workpiece that needs to be sandblasted into the U-shaped groove 205 of the four sets of U-shaped frames 204. By rotating the clamping bolt 206, make the anti-slip pad 209 on the side near the sleeve 202 contact and press against the workpiece surface, thereby fixing the workpiece on the U-shaped frame 204.

[0038] Subsequently, the height and horizontal distance of the sandblasting gun 310 are adjusted according to processing requirements. When adjusting the horizontal position of the sandblasting gun 310, the electric actuator 304 is activated. The output end of the electric actuator 304 pushes the movable plate 301, which slides horizontally along the first guide post 303, thereby driving the sandblasting gun 310 mounted on the movable plate 301 to move horizontally, facilitating the adjustment of the distance between the sandblasting gun 310 and the workpiece. When adjusting the height position of the sandblasting gun 310, since the second guide post 309 is located between the top and bottom walls of the slide groove 305, the top of the threaded rod 308... The top of the movable plate 301 is connected to the output end of the second drive motor 306. The bottom of the threaded rod 308 is rotatably connected to the bottom wall of the movable plate 301. The inner wall of the U-shaped plate 307 is threadedly connected to the threaded rod 308. The inner wall of the U-shaped plate 307 is slidably connected to the second guide post 309. When the threaded rod 308 rotates, the U-shaped plate 307 slides up and down along the second guide post 309 in the slide groove 305. The sandblasting gun 310 installed on the outside of the U-shaped plate 307 moves up and down with the U-shaped plate 307 to adjust the height of the sandblasting gun 310 for easy and uniform sandblasting.

[0039] Synchronously, the first drive motor 210 is started. The output end of the first drive motor 210 drives the pinion 211 to rotate. Since the pinion 211 meshes with the large gear 212, the rotation of the pinion 211 drives the large gear 212 to rotate. Since the bottom of the shaft 201 is connected to the large gear 212, the rotation of the large gear 212 drives the shaft 201 to rotate. Also, since the protrusion on the inner wall of the sleeve 202 matches the concave part on the surface of the shaft 201, the rotation of the shaft 201 will drive the sleeve 202 to rotate, which in turn drives the four sets of U-shaped frames 204 sleeved on the outside of the sleeve 202 to rotate.

[0040] After the four sets of U-shaped frames 204 rotate to the appropriate position, the sandblasting guns 310 located on both sides of the processing table 1 simultaneously perform double-sided sandblasting on the workpieces fixed on the U-shaped frames 204. The four sets of U-shaped frames 204 rotate continuously, taking turns to send the workpieces on each U-shaped frame 204 into the working range of the sandblasting guns 310, realizing continuous processing and effectively improving processing efficiency.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
