A pair of telescopic rods A8 are provided on the top of the processing box 1, and the telescopic rods A8 are along the vertical direction. A lifting plate 2 is provided in the processing box 1. The movable rod of the telescopic rod A8 penetrates into the processing box 1 and is connected to the left and right sides of the lifting plate 2. A pair of rotating rollers 9 are provided at the bottom of the lifting plate 2, and one end of the rotating shaft of the rotating roller 9 is connected to the driving rod of the motor AI0. The two rotating rollers 9 are covered with an annular grinding belt 3. The lifting plate 2 is provided with a lifting plate 2. The movable rod of the telescopic rod A8 penetrates into the processing box 1 and is connected to the left and right sides of the lifting plate 2. The lifting plate 2 is provided with a pair of rotating rollers 9 that are symmetrical front and back. One end of the rotating shaft of the rotating roller 9 is connected to the driving rod of the motor AI0. The two rotating rollers 9 are covered with an annular grinding belt 3. A mounting table 5 is provided under the plate 2, a support table 7 is provided at the bottom center of the processing box 1, a rotating seat 6 is provided on the top of the support table 7, the bottom of the mounting table 5 is rotatably connected to the rotating seat 6, a motor B11 is provided in the support table 7, the driving rod of the motor B11 passes through the rotating seat 6 and is coaxially connected to the bottom center of the mounting table 5, and a discharge plate 4 is detachably connected to the top of the mounting table 5. The discharge plate 4 is in the downward projection surface of the annular grinding belt 3, and placement grooves 12 are evenly provided on the discharge plate 4. The hinges to be processed are placed in the placement grooves 12. A material changing port 13 is provided on the front of the processing box 1, which is aligned with the top of the mounting table 5, and a sealing door 14 is hinged on the material changing port 13.

[0029] By using the motor AI0, the rotating seat 6 and the mounting table 5 in combination, the function of adjusting the orientation of the material discharge plate 4 placed on the mounting table 5 and the hinge to be processed placed on the material discharge plate 4 is obtained, so that the hinge can change its orientation multiple times, and the annular grinding belt 3 is polished after each change of orientation, thereby reducing the possibility of burrs that are difficult to process in certain orientations remaining and improving the effect of burr processing; the motor AI0 is used to drive the rotating roller 9 to rotate, and the rotating rotating roller 9 drives the annular grinding belt 3 to rotate, and the rotating annular grinding belt 3 can grind away the burrs. The burrs on the hinge surface are removed by rotating the mounting platform 5 via motor B11. The rotating mounting platform 5 drives the unloading plate 4 and the hinge to rotate, thereby changing the direction of the hinge. The height of the lifting plate 2 is adjusted via telescopic rod A8, thereby changing the height of the annular grinding belt 3 indirectly connected to the lifting plate 2, thereby controlling the distance between the lower surface of the annular grinding belt 3 and the hinge. Each time the direction of the hinge is changed, the annular grinding belt 3 is raised to break away from contact with the hinge. After the direction of the hinge is changed, the annular grinding belt 3 is lowered to abut the hinge. The unloading plate 4 is evenly provided with a number of placement slots 12 for placing hinges. Firstly, the unloading plate 4 can accommodate multiple hinges, and the annular grinding belt 3 that can cover the unloading plate 4 can achieve the effect of processing multiple hinges simultaneously, improving processing efficiency. Secondly, the hinge installation is simple, reducing the workload of hinge assembly and disassembly. The deburring operation is restricted to a processing box 1 isolated from the outside world, thereby avoiding the diffusion of debris generated during the operation, reducing the impact on the working environment, and protecting the health of the workers; the workers take and place the discharge plate 4 into the processing box 1 through the material exchange port 13, and the sealing door 14 on the material exchange port 13 needs to be opened when using the material exchange port 13.

The telescopic rod B16 is along the vertical direction, and a rotating seat 17 is provided on the top of the movable rod of the telescopic rod B16. A tightening roller 18 is rotatably connected between the two rotating seats 17, and the upper surface of the tightening roller 18 rolls and abuts against the upper inner portion of the annular grinding belt 3.

[0031] The height of the rotating seat 17 is adjusted by the telescopic rod B16, thereby adjusting the height of the tightening roller 18 connected to the rotating seat 17. The tightness of the annular grinding belt 3 is changed by lifting and lowering the tightening roller 18, so that the annular grinding belt 3 maintains sufficient force to remove burrs and improve the processing effect.

[0032] Furthermore, the left and right side walls inside the processing box 1 are respectively provided with a limit rod 19, and the limit rod 19 is along the vertical direction. The left and right sides of the lifting plate 2 are provided with limit sleeves 20 corresponding to the limit rod 19, and the limit sleeves 20 are sleeved on the corresponding limit rod 19, and the limit sleeves 20 are slidably connected to the limit rod 19.

[0033] By using the limiting rod 19 and the limiting sleeve 20 in combination, the moving direction of the lifting plate 2 is stabilized.

[0034] Furthermore, a plurality of through holes 21 are provided on the discharge plate 4 , and insertion rods 22 corresponding to the through holes 21 are provided on the top of the mounting platform 5 , and the insertion rods 22 are inserted into the through holes 21 .

[0035] The combination of the insert rod 22 and the through hole 21 prevents the unloading plate 4 from sliding away from the correct installation position, and the installation and removal of the unloading plate 4 onto the installation platform 5 is simple.

[0036] Furthermore, an elastic block 23 is provided on the side wall of the placement groove 12, and the elastic block 23 abuts against the side wall of the bottom of the hinge to be processed.

[0037] The hinge is further restricted in the placement slot 12 by the clamping of the elastic blocks 23 . When the hinge is placed in or removed from the placement slot 12 , it only needs to overcome the elastic force of the elastic blocks 23 , which is easy to operate.

[0038] Furthermore, a horizontal grid plate 24 is provided inside the processing box 1 , and an opening 25 for the installation platform 5 to pass through is provided in the middle of the grid plate 24 .

[0039] The grid plate 24 is used to block the discharge plate 4 from falling by mistake, while ensuring that the debris can fall smoothly to the bottom of the processing box 1, thereby improving the fault tolerance of use.

[0040] Furthermore, a waste removal opening 26 is provided on the front of the processing box 1 and is aligned with the bottom of the processing box 1 , and a sealing door 14 is hinged on the waste removal opening 26 .

[0041] The waste outlet 26 is used to facilitate the staff to clean up the debris accumulated at the bottom of the processing box 1 afterwards. When cleaning, the staff only needs to open the sealed door 14 of the waste outlet 26 and clean the debris from the waste outlet 26.

[0042] Furthermore, an air inlet 27 is provided at the top of the front side of the processing box 1, and an air outlet 28 is provided at the bottom of the back side of the processing box 1.

An air pump 30 is provided at the air outlet 28 on the back side of the processing box 1, and the inlet of the air pump 30 is connected to the air outlet 28.

[0043] By using the air inlet 27, the air outlet 28 and the vacuum pump 30 in combination, wind flowing from the top to the bottom is created, helping the debris to fall more easily to the bottom of the processing box 1. The filter 29 on the air inlet 27 is used to prevent external impurities from entering the processing box 1, and the filter 29 on the air outlet 28 is used to prevent the debris in the processing box 1 from mixing into the vacuum pump 30 and being discharged to the outside.

[0044] The working principle and use process of this utility model:

[0045] The staff puts the hinges to be processed into the placement groove 12 one by one, and then installs the discharge plate 4 with the hinges installed on the mounting table 5 from the refueling port 13. After closing the sealed door 14 of the refueling port 13, start the vacuum pump 30, start the motor AI0 to let the annular grinding belt 3 start to rotate, and adjust the tightness of the annular grinding belt 3 through the telescopic rod B16. After debugging the annular grinding belt 3, press the annular grinding belt 3 onto the hinge through the telescopic rod A8. After processing for a certain period of time, raise the annular grinding belt 3, and then start the motor B11 to rotate the hinge to a new direction, and then lower the annular grinding belt 3 to press the hinge. After changing the hinge direction several times and re-grinding the hinge, the deburring operation of the hinge is completed, the annular grinding belt 3 is raised and reset, the motor AI0 and the vacuum pump 30 are closed, the sealed door 14 of the refueling port 13 is opened, the discharge plate 4 is removed, and the processed hinge is removed. When cleaning up afterwards, the sealing door 14 on the waste taking-out opening 26 is opened and the accumulated debris is cleared out from the waste taking-out opening 26 .
