Description

Technical Field

[0001] The utility model belongs to the technical field of barrel making equipment and relates to an edge grinding mechanism for barrel cover processing. Background Art

[0002] The bottom cover and top cover of the metal packaging barrel are first punched into sheets, then pre-curled, and finally made with the barrel body. The edges of the circular sheets after stamping may be uneven with burrs and other irregularities. The existing practice is: after cutting, the edge is immediately ground and then pre-curled. In the actual production process, it is found that the pre-curling operation also has errors in the curling height. After the curling is completed, appropriate grinding is also required to ensure that the thickness of the flange formed after pre-curling is consistent. Therefore, the existing barrel cover processing requires two grinding and trimming processes. Utility Model Content

[0003] The purpose of the utility model is to provide an edge grinding mechanism for barrel cover processing in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to efficiently complete the edge grinding of the barrel cover.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a grinding mechanism for barrel cover processing, characterized in that it includes a feed conveyor line, a discharge conveyor line and a grinding host, the grinding host includes a frame, a motor and a grinding disc, the frame has an outer guard ring, an annular material trough is formed between the inner wall surface of the outer guard ring and the outer wall surface of the grinding disc, the material trough has two notches respectively connected with the feed conveyor line and the discharge conveyor line, the body of the motor is fixed on the frame, and the output shaft of the motor is connected to the grinding disc.

[0005] Furthermore, both the inner wall and the outer wall of the material trough have limiting grooves adapted to the barrel cover.

[0006] Furthermore, there is a gap between the grinding disc and the material trough, which is used to allow the powder generated by edge grinding to fall off and is also conducive to heat dissipation.

[0007] After the barrel cover is pre-curled, it enters the trough from the feeding conveyor line, and the motor drives the grinding disc to rotate. The rotation of the grinding disc not only drives the barrel cover to move in the trough, but also drives the barrel cover to move relative to the grinding disc, that is, the barrel cover is in a state of self-rotation and revolution around the center of the trough in the trough. Of course, this movement is not completely regular and there is a certain randomness. However, on the whole, when the barrel cover is pre-curled downward, the curling position can rub against the grinding disc to achieve trimming and grinding, and finally it is discharged from the discharging conveyor line.

[0008] The limiting grooves arranged on the inner and outer walls of the trough can ensure that the barrel cover will not fall off the trough, and have a positive effect on the effective contact between the barrel cover and the grinding disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 and Figure 2 As shown, the edge grinding mechanism for barrel cover processing includes a feed conveyor line 1, a discharge conveyor line 2 and an edge grinding main machine, the edge grinding main machine includes a frame 3, a motor 4 and a grinding disc 5, the frame 3 is provided with an outer guard ring, an annular material trough 6 is formed between the inner wall surface of the outer guard ring and the outer wall surface of the grinding disc 5, the material trough 6 has two notches respectively connected with the feed conveyor line 1 and the discharge conveyor line 2, the body of the motor 4 is fixed on the frame 3, and the output shaft of the motor 4 is connected to the grinding disc 5.

[0014] The inner and outer walls of the material trough 6 are both provided with limiting grooves 7 adapted to the barrel cover.

[0015] There is a gap between the grinding disc 5 and the material trough 6. This gap is used to allow the powder produced by the edge grinding to fall off and is also conducive to heat dissipation.

[0016] After the barrel cover is pre-curled, it enters the material trough 6 from the feeding conveyor line 1, and the motor 4 drives the grinding disc 5 to rotate. The rotation of the grinding disc 5 not only drives the barrel cover to move in the material trough 6, but also drives the barrel cover to move relative to the grinding disc 5, that is, the barrel cover is in a state of self-rotation and revolution around the center of the material trough 6 in the material trough 6. Of course, this movement is not completely regular and there is a certain randomness. However, on the whole, when the barrel cover is pre-curled downward, the curling position can rub against the grinding disc 5 to achieve trimming and grinding, and finally it is discharged from the discharging conveyor line 2.

[0017] The limiting grooves 7 provided on the inner and outer walls of the material trough 6 can ensure that the barrel cover will not be separated from the material trough 6 and have a positive effect on the effective contact between the barrel cover and the grinding disc 5.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
