The telescopic column 3 can be telescoped in the vertical direction under the control of the telescopic controller 4. A placement and fixing assembly 6 is arranged at the middle position of the top surface of the base 1. The upper end of the telescopic column 3 is connected to the lower surface of the top plate 2. A left-right moving assembly 5 is arranged on the lower surface of the top plate 2. The cutting assembly 7 is vertically connected below the moving assembly 5.

[0036] Adjust the length of the telescopic column 3 through the telescopic controller 3 to adjust the height of the cutting assembly 7, so as to facilitate trimming two-piece cans of different heights. Adjust the position of the cutting assembly 7 horizontally through the moving assembly 5 to trim two-piece cans of different sizes. It is also possible to adjust the above-mentioned telescopic column 3 and the moving assembly 5 simultaneously to trim two-piece cans.

[0037] Furthermore,

[0038] The moving component 5 includes a fixed block 50, a stepping motor 51, a threaded connection cylinder 52, a lead screw 53, a threaded slider 54, a slide rail 55, and a slide rail slider 56. The fixed blocks 50 are arranged on the left and right sides of the lower surface of the top plate, and the two fixed blocks 50 correspond to each other on the same straight line. There is a left-right slide rail 55 installed on the lower surface of the top plate 2 in the area between the two fixed blocks 50. A slidable slide rail slider 56 is arranged on the slide rail 55. The end of the slide rail slider 56 is connected to the upper part of the threaded slider 54.

A small threaded hole is opened at the center position of the turntable 61. The suction cup 62 with a threaded small hole is installed at the center of the turntable 61. The suction cup 62 is connected to the micro vacuum pump 63 through a hose. The micro vacuum pump 63 is fixedly installed on the turntable 61. The suction cup 62 and the micro vacuum pump 63 are used in cooperation to fix two cans. While the turntable 61 drives the suction cup 62 to rotate, the two cans also rotate together, realizing the cutting of different positions on the edges of the two cans.

[0043] Further,

[0044] Through holes 501 that are exactly large enough for the lead screw 53 to pass through are opened at the corresponding positions of the two fixed blocks 50.

[0045] Furthermore,

[0046] The inner side of the threaded slider 54 is provided with an internal thread adapted to the thread on the lead screw 53.

[0047] Furthermore,

[0048] The suction cup 62 includes a connecting pipe 620, a connecting disc 621, and a suction cup head 622.

The upper end of the connecting pipe 620 is connected to the connecting disc 621 through the small hole, and the suction cup head 622 is installed at the edge of the upper surface of the connecting disc 621.

[0049] The usage mode of the present utility model is as follows:

[0050] Before trimming the two-piece can empty can, place the two-piece can empty can on the suction cup head 622 of the suction cup 62. The threaded small hole provided in the middle of the connecting pipe 620 of the suction cup 62 is hermetically connected through a connecting piece with the hose, and the other end of the hose is hermetically connected to the air outlet of the micro vacuum pump 63.

[0051] Start the micro vacuum pump 63. The micro vacuum pump 63 discharges the air between the suction cup 62 and the bottom of the two-piece can empty can, so that a negative pressure is formed between the suction cup 62 and the bottom of the two-piece can empty can. The two-piece can empty can is fixed on the suction cup 62 through the atmospheric pressure. Such a fixing method will not cause damage to the can body due to the contact between the fixture and the two-piece can empty can body.

[0052] After that, through the telescopic controller 3 on the side of the base 1, control the telescopic column 4 to contract downward. Since the top end of the telescopic column 4 is connected to the top plate 2 and the moving assembly 5 is installed on the lower surface of the top plate 2, when the telescopic column 4 contracts downward, it will drive the top plate 2 and the moving assembly 5 installed on the lower surface to move together until adjusted to the appropriate cutting height.

[0053] At this time, start the stepping motor 51 in the moving assembly 5. The stepping motor 51 is connected to the lead screw 53 through the threaded connection cylinder 52. When the stepping motor 51 rotates, it will drive the threaded slider 54 sleeved on the lead screw 53 and having an internal thread adapted to the lead screw 53 to move. When the threaded slider 54 moves to one end, the stepping motor 51 will reverse, so that the threaded slider 54 moves in the opposite direction, realizing the uniform reciprocating movement of the threaded slider 54 in the horizontal direction on the lead screw 53. The lower surface of the threaded slider 54 is connected to the cutting tool 71. When moving to the appropriate position, turn off the stepping motor 51 to make the threaded slider 54 stop at the appropriate position, and the cutting tool 71 also stops at the appropriate cutting position.

[0054] At this time, start the drive motor 72 that connects the cutting knife 71 to make the cutting knife 71 rotate for a trial cut to check if the cutting position is correct. If not, turn off the drive motor 72 and continue to adjust. If the cutting position is correct, start the turntable 61. The turntable 61 drives the micro vacuum pump 63, the suction cup 62, and the two empty cans fixed on the suction cup 62 to rotate together, and cooperate with the cutting knife 71 beside to complete the entire cutting process.

[0055] After the cutting is completed, press the switch of the turntable 61 to turn off the turntable 61. At the same time, also turn off the micro vacuum pump 63 and the cutting knife motor 72, and then remove the two empty cans to complete the operation.
