Description

Technical Field

[0001] This utility model relates to the technical field of rust removal devices, specifically to a rust removal device for a rotating arm connection. Background Technology

[0002] The cartridge filter section includes components such as a frame, rotating arm, dust collection fan, dust collector, and dust collection box. When the cartridge filter section is working, the dust drawn in by the dust collection fan first passes through the rotating arm and the suction pipe into the dust collector for dust-air separation, and finally is sent into the dust collection box.

[0003] The rotating arm rotates during operation, and under normal working conditions, the connection between the rotating arm and the suction hose can rotate smoothly. However, after long-term use, the outer surface of the rotating arm connection is prone to corrosion. The resulting corrosion and rust cause the rotation between the connection and the suction hose to become uneven, leading to twisting and deformation of the suction hose, and ultimately, breakage of the suction hose.

[0034] like Figures 1-6 As shown, this utility model provides a rust removal device for the connecting part of a rotating arm, which is used in conjunction with a rotating arm. The rotating arm includes a rotating arm connecting part 11 and a rotating arm mounting part 12. A dust removal channel 13 is formed inside the rotating arm connecting part 11. The dust removal pipe is sleeved on the outer surface of the rotating arm connecting part 11 during use. The above contents are all prior art, and the specific structure will not be described in detail here. This device also includes a base 20, a vertical plate 30, a rotating disk 31, a pressure ring 40, screws 32, a motor 50, a locking assembly 60, and sandpaper 70.

[0035] The base 20 is placed on the ground.

[0036] The upright plate 30 is fixedly installed on the base 20 along the longitudinal direction, and the upright plate 30 has a rotating groove 33 that runs through it in the transverse direction.

[0037] The rotating disk 31 is disposed in the rotating groove 33 and is adapted to the rotating groove 33. The axis of the rotating disk 31 is arranged in a transverse direction. The rotating disk 31 is rotatably connected to the inner wall of the rotating groove 33. Multiple first threaded holes 34 are opened on the rotating disk 31.

[0038] An annular groove 41 is formed on the end face of the pressure ring 40, and the annular groove 41 is adapted to the rotating arm mounting part 12. A through hole 42 is formed at the bottom of the annular groove 41, and the through hole 42 is adapted to the rotating arm connecting part 11.

[0039] There are multiple screws 32, and each screw 32 corresponds to one of the multiple first threaded holes 34. The threaded end of the screw 32 passes through the pressure ring 40 and engages with the first threaded hole 34. The head of the screw 32 fixes the rotating arm mounting part 12 to the rotating disk 31. Preferably, there are three screws 32 and three first threaded holes 34.

[0040] The motor 50 is fixedly mounted on the upright plate 30 and is used to control the rotation of the rotating disk 31.

[0041] There are two locking components 60, which are respectively located on both sides of the rotating disk 31.

[0042] The middle part of the sandpaper 70 contacts the rotating arm connecting part 11, and the two ends of the sandpaper 70 are detachably connected to two locking components 60 respectively.

[0043] The specific operating procedure of this device is as follows: First, the operator attaches the rotating arm mounting part 12 to the rotating disk 31, and fixes the rotating arm to the rotating disk 31 by engaging the threaded end of the screw 32 with the first threaded hole 34. Then, the two ends of the sandpaper 70 are fixed by the two locking components 60, at which point the sandpaper 70 is in contact with the outer surface of the rotating arm connecting part 11. Next, the control motor 50 is started, and the motor 50 drives the rotating disk 31 and the rotating arm to rotate, allowing the sandpaper 70 to perform all-round rust removal on the outer surface of the rotating arm connecting part 11.

[0044] After the rust removal work is completed, the workers can then remove the rotating arm.

[0045] In one embodiment, the locking component 60 includes a locking plate 61 and a locking block 62.

[0046] The locking plate 61 is fixedly mounted on the upright plate 30. A locking groove 63 is formed on the inner side of the locking plate 61, and a second threaded hole extending downwards is formed at the bottom of the locking groove 63. A locking block 62 is disposed within the locking groove 63. The first end of the locking block 62 is rotatably connected to the inner wall of the locking groove 63, and the second end of the locking block 62 is provided with a self-tapping screw 64. The tip of the self-tapping screw 64 passes through the sandpaper 70 and engages with the threaded hole in the second threaded hole. The head of the self-tapping screw 64 fixes the locking block 62 within the locking groove 63.

[0047] When installing the sandpaper 70, the worker first flips up the second end of the locking block 62, then puts both ends of the sandpaper 70 into the two locking slots 63 respectively, then puts down the second end of the locking block 62, and then screws the self-tapping screw 64 until the tip of the self-tapping screw 64 passes through the sandpaper 70 and engages with the threaded hole of the second threaded hole. At this time, the locking block 62 will press the end of the sandpaper 70 tightly, so that the middle part of the sandpaper 70 keeps in contact with the outer surface of the rotating arm connecting part 11.

[0048] This locking component 60 has a simple structure and is easy to operate.

[0049] In one embodiment, the device further includes a pressing assembly 80, which includes a fixing plate 81, a guide rod 82, an arc plate 83, and a spring 84.

[0050] A fixed plate 81 is positioned above the rotating disk 31 and is fixedly connected to the upright plate 30. A guide rod 82 passes longitudinally through the fixed plate 81 and is slidably connected to the fixed plate 81. An arc-shaped plate 83 is adapted to the rotating arm connecting part 11 and contacts the sandpaper 70; the arc-shaped plate 83 is fixedly connected to the guide rod 82. A spring 84 is sleeved on the guide rod 82; both ends of the spring 84 are fixedly connected to the fixed plate 81 and the arc-shaped plate 83, respectively, and the spring 84 causes the guide rod 82 to have a downward tendency.

[0051] During rust removal, the arc plate 83 presses firmly against the sandpaper 70 due to the action of the spring 84, thus making the sandpaper 70 adhere tightly to the outer surface of the rotating arm connection 11 and improving the rust removal effect.

[0052] In one embodiment, the device further includes a latch assembly 90, which includes a hook 91 and a latch plate 92. The hook 91 is fixedly mounted on a fixed plate 81. The latch plate 92 is disposed below the fixed plate 81, with its first end rotatably connected to a guide rod 82 and its second end having a hanging hole that is adapted to the hook 91.

[0053] In the initial state, the hanging holes on the platform 92 are hooked onto the hook 91, so the arc plate 83 will not move downwards, making it convenient for workers to fix the rotating arm onto the rotating plate 31.

[0054] After the workers secure the two ends of the sandpaper 70 using the two locking components 60, they can remove the hanging hole from the hook 91. At this point, under the action of the spring 84, the curved plate 83 will press firmly onto the sandpaper 70.

[0055] In one embodiment, a positioning post 35 is also included. The positioning post 35 is fixedly installed on the rotating disk 31. The axis of the positioning post 35 is collinear with the axis of the rotating disk 31. The positioning post 35 is inserted into the dust removal channel 13 of the rotating arm connecting part 11, and the positioning post 35 is adapted to the dust removal channel 13.

[0056] When installing the rotating arm, the workers first align the dust removal channel 13 with the positioning column 35, and then rotate the rotating arm so that the screw 32 is aligned with the first threaded hole 34. Then, they tighten the screw 32, and the threaded end of the screw 32 aligns with the first threaded hole 34, thereby fixing the rotating arm on the rotating disk 31.

[0057] In one embodiment, a reinforcing rib 21 is also included, which is fixedly connected to both the base 20 and the upright plate 30.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
