[0034] A second motor 10 is arranged above the installation plate 7; the output shaft of the second motor 10 penetrates through the installation plate 7 downward and is connected to the top of the transmission screw rod 8;

[0035] A polishing assembly is arranged below the adjusting rod 11 and comprises a fixed seat 12 and a fixed seat 13; a first polishing wheel 14 is arranged on the fixed seat 12, and a second polishing wheel 15 is arranged on the fixed seat 13; the fixed seat 12 is connected to the sliding seat 9 through a connecting frame 16; an electric push rod 28 is arranged in the connecting frame 16; the electric push rod 28 is fixed on the rear baffle 34 of the connecting frame 16, and the telescopic end of the electric push rod 28 is connected to the front baffle 34 of the connecting frame 16; the front end of the top plate and the bottom plate of the connecting frame 16 is welded and fixed to the front baffle 34; when the electric push rod 28 works, the telescopic end of the electric push rod 28 drives the front baffle 34, the top plate and the bottom plate of the connecting frame 16 to move.

[0036] In this embodiment, the bottom of the plastic bucket is placed in the limiting groove 3 in the middle of the rotating disc 2; the clamping assembly can clamp and limit the bottom of the plastic bucket body through the movable clamping plate 21 on the movable plate 18, in cooperation with the fixed clamping plate 20 on the fixed plate 17; finally, the plastic bucket can be clamped and limited by locking the nut and the threaded rod 19, which is beneficial to avoid the plastic bucket body from shaking randomly during the operation of removing the burr.

[0037] On the other hand, the adjusting rod 11 is provided with a guide groove two 22, and a guide rod 23 is arranged in the guide groove two 22; the fixed seat two 13 is fixed with a guide plate 24 through a bolt, the top of the guide plate 24 is located in the guide groove two 22 and is in sliding fit with the guide rod 23; a compression spring 25 is sleeved on the guide rod 23, one end of the compression spring 25 abuts against the inner wall of the guide groove two 22, and the other end abuts against the top of the guide plate 24 away from the second grinding wheel 15; the top of the guide plate 24 is provided with a push piece 26, and the push piece 26 is located above the guide groove two 22. The staff can manually push the push piece 26 to drive the guide plate 24 to move in the guide groove two 22, so as to adjust the position of the second grinding wheel 15. When the top of the side wall of the plastic bucket is placed between the first grinding wheel 14 and the second grinding wheel 15, the staff loosens the push piece 26, and the second grinding wheel 15 abuts against the inner wall of the plastic bucket opening under the elastic force of the compression spring 25. At this time, only the electric push rod 28 needs to be started to push the first grinding wheel 14 to abut against the outer wall of the plastic bucket opening, and then the first motor 4 is started to drive the turntable 2 and the plastic bucket to rotate, so that the burrs on the plastic bucket opening can be removed.

[0038] In addition, the fixed seat one 12 is provided with a rotating shaft 27 penetrating the first grinding wheel 14, and the two ends of the rotating shaft 27 are locked by nuts; the top of the rotating shaft 27 penetrates the adjusting rod 11 and is rotatably connected with the adjusting rod 11, the adjusting rod 11 can rotate along the rotating shaft 27, thereby driving the second grinding wheel 15 to rotate by a certain angle. The top plate of the connecting frame 16 is provided with a sliding groove 29, and a limiting plate 30 in sliding fit with the sliding groove 29 is arranged in the sliding groove 29; the limiting plate 30 is provided with a guide groove three 31; the sliding groove 29 is further provided with a vertical upward positioning column 32, the positioning column 32 penetrates the guide groove three 31 upward and is locked by a nut; the end of the limiting plate 30 away from the sliding seat 9 is provided with an avoiding groove 33, the avoiding groove 33 is penetrated by the rotating shaft 27 and is locked by a nut; the adjusting rod 11 is provided with an upward protruding baffle 34, one side of the baffle 34 abuts against the side of the limiting plate 30 away from the sliding seat 9.

[0039] When the avoiding groove 33 is penetrated by the rotating shaft 27 and locked by a nut, the adjusting rod 11 cannot rotate, and the relative position of the first grinding wheel 14 and the second grinding wheel 15 does not change; when the nuts locking the avoiding groove 33 and the rotating shaft 27 are loosened, the nuts on the positioning column 32 are also loosened, at this time, the limiting plate 30 can be manually slid to make the two sides of the avoiding groove 33 retract into the sliding groove 29; then, the staff can rotate the adjusting rod 11 to drive the second grinding wheel 15 to rotate clockwise or counterclockwise by 90°, then the end of the limiting plate 30 provided with the avoiding groove 33 is slid out of the sliding groove 29 to contact the rotating shaft 27, and finally the two nuts loosened before are tightened, so that the first grinding wheel 14 and the second grinding wheel 15 are located outside the plastic bucket body, which is convenient for removing the burrs existing on the outer wall of the plastic bucket.

[0040] When the second grinding wheel 15 rotates to the outside of the plastic bucket, the second motor 10 is started to drive the sliding seat 9 to move up and down along the transmission screw rod 8. The first grinding wheel 14 is in contact with the outer wall of the plastic bucket under the pushing of the electric push rod 28, and the first grinding wheel 14 can remove the vertical burrs on the outer wall of the plastic bucket when the second motor 10 works. At this time, the first motor 4 does not work, and the plastic bucket does not rotate. When the second motor 10 stops working, the first grinding wheel 14 stops at a certain height and is at the same height with the horizontal burrs on the plastic bucket. At this time, the first motor 4 is started to drive the plastic bucket to rotate, which can facilitate the first grinding wheel 14 to remove the horizontal burrs on the plastic bucket. It should be noted that when the first grinding wheel 14 removes the vertical or horizontal burrs on the outer wall of the plastic bucket, the second grinding wheel 15 does not contact the outer wall of the plastic bucket.

[0041] The plastic bucket edge removing device has the advantages that two grinding wheels are arranged, the burrs on the bucket opening and the upper body of the plastic bucket can be removed, the grinding area of the grinding wheel is small, the normal smooth surface of the plastic bucket is not damaged, the quality of the finished product is not affected, the device is practical, and has good market application prospect.

[0042] The foregoing description of specific exemplary embodiments of the present application is intended to be illustrative only and is not intended to limit the present application to the precise forms described. Many modifications and variations are possible in light of the above teachings without departing from the spirit or essential characteristics of the present application. The exemplary embodiments were chosen and described in order to explain the principles of the present application and its practical application and to allow others skilled in the art to understand the present application for various exemplary embodiments with various modifications being applicable.
