[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a bend grinding device with a cleaning structure, wherein an isolation box 2 is installed above the processing table 1, and the bend clamping mechanism 3 and the bend grinding mechanism 4 are provided inside the isolation box 2, and the isolation box 2 is connected to the purification box 6 through the conveying pipe 5.

[0025] In a further embodiment, the isolation box 2 is provided with a door on one side, and dustproof and ventilation holes can be opened on the door.

[0026] Specifically, the elbow clamping mechanism 3 includes a mounting groove 301, and a drive block 302 is slidably disposed inside the mounting groove 301. The drive block 302 is connected to an electric lead screw mechanism 303 disposed inside the mounting groove 301. The electric lead screw mechanism 303 includes a first lead screw mechanism, one end of which is connected to a motor. The top of the drive block 302 is connected to a lower clamping block 305 via a connecting block 304. An upper clamping block 306 is mounted above the lower clamping block 305 for use therewith. The top of the upper clamping block 306 is connected to a mounting frame 3062 via a first electric telescopic rod 3061. The mounting frame 3062 is mounted on the outside of the connecting block 304. Limiting slide rods 3063 are provided on both sides of the upper clamping block 306, and the limiting slide rods 3063 are slidably connected to the inside of the mounting frame 3062. By setting the limiting slide rods 3063, the movement direction of the upper clamping block 306 can be limited. To improve the stability of the upper clamping block 306 during movement, an L-shaped support plate 307 is provided on one side of the connecting block 304. The L-shaped support plate 307 is connected to the limiting plate 309 via the second electric telescopic rod 308. When it is necessary to clamp the elbow, the elbow is placed above the lower clamping block 305. After placement, the first electric telescopic rod 3061 is activated, causing the upper clamping block 306 to move down and cooperate with the lower clamping block 305 to clamp and limit the elbow. After clamping, the second electric telescopic rod 308 is activated, so that the limiting plate 309 contacts the outside of the elbow. The setting of the limiting plate 309 can prevent the elbow from moving backward under force during the grinding process. When it is necessary to drive the clamped elbow to move, the electric screw mechanism 303 is activated. The electric screw mechanism 303 can drive the driving block 302 and the clamped elbow to move, so that the elbow is close to the elbow grinding mechanism 4 for grinding operation.

[0027] To further explain, the elbow grinding mechanism 4 includes a first drive motor 401, and the first drive motor 401 can drive the grinding wheel 402 to rotate and grind. The first drive motor 401 is installed above the support block 403.

[0028] Specifically, the purification box 6 has two sets of filters 601 installed inside. A dust outlet 602 is located at the bottom of the purification box 6, on one side of the filters 601. A removable sealing plate is installed inside the dust outlet 602. This removable sealing plate can seal the dust outlet 602 under certain conditions, preventing impurities and dust from overflowing from the dust collection box 603. The dust outlet 602 is connected to the dust collection box 603 located at the bottom of the outer side of the purification box 6. The bottom of the dust collection box 603 has an impurity discharge port. The interior of the purification box 6 is far from the conveying system. A blower 604 is installed at one end of the delivery pipe 5, and a filter cleaning mechanism 605 is installed inside the purification box 6 to work with two sets of filter screens 601. During grinding, the door of the isolation box 2 is closed to prevent the dust-laden gas generated during grinding from overflowing. The blower 604 is turned on, and under the action of the blower 604, the dust-laden gas inside the isolation box 2 enters the purification box 6 through the delivery pipe 5. The two sets of filter screens 601 inside the purification box 6 can filter the dust and impurities in the gas before discharging it.

[0029] Specifically, the filter cleaning mechanism 605 includes a second drive motor 6051, and the output end of the second drive motor 6051 can drive the first gear 6053 set inside the mounting box 6052 to rotate via a drive rod. The first gear 6053 meshes with the second gears 6054 set on both sides, and the second gears 6054 are installed on the outside of the lead screw mechanism 6055. One end of the lead screw mechanism 6055 extends into the purification box 6, and the outside of the lead screw mechanism 6055 is connected to the moving block 6056. A long-handled cleaning brush 6057 is installed on one side of the moving block 6056, and the long-handled cleaning brush 6057 contains... The brush head contacts the outer side of the two sets of filter screens 601. When it is necessary to clean the surface of the filter screen 601, the second drive motor 6051 is turned on. Under the action of the second drive motor 6051, the first gear 6053 rotates. The first gear 6053 can drive the second gear 6054 and the lead screw mechanism 6055 set on both sides to rotate. Under the action of the lead screw mechanism 6055, the moving block 6056 moves, thereby driving the long rod cleaning brush 6057 to move and brush the outer side of the filter screen 601. The impurities that fall off the brush enter the dust collection box 603 through the dust outlet 602.
