DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0031] Example 1

[0032] A PP plate positioning and slotting device, see Figure 1-Figure 6As shown, it includes a support frame 1, a mounting frame 2, a workbench 3, a fixed seat 4, an electric slotting machine 5, a pushing mechanism 6 and a positioning mechanism 7. The mounting frame 2 is fixedly connected to the top of the support frame 1, the workbench 3 is fixedly connected to the right side of the mounting frame 2, the fixed seat 4 is welded to the bottom of the workbench 3, the electric slotting machine 5 is fixedly connected to the fixed seat 4, and the slotting blade of the electric slotting machine 5 passes through the middle of the workbench 3. The pushing mechanism 6 is arranged on the upper right part of the mounting frame 2, and the positioning mechanism 7 is arranged on the upper left part of the mounting frame 2.

[0033] See also Figure 1 , Figure 4 and Figure 5 As shown, the pushing mechanism 6 includes a first slide bar 601, a mounting frame 602, a first elastic member 603, a roller 604 and a first servo motor 605. The first slide bar 601 is slidably arranged on the upper right part of the mounting frame 2, and the bottom end of the first slide bar 601 is fixedly connected to the mounting frame 602. The left side of the top inside the mounting frame 602 is an inclined surface. A first elastic member 603 is connected between the top of the mounting frame 602 and the mounting frame 2. The first elastic member 603 is sleeved on the first slide bar 601. A plurality of rollers 604 are rotatably arranged at even intervals inside the mounting frame 602. The first servo motor 605 is provided on the front side of the left part of the mounting frame 602 by bolt connection. The front end of the roller 604 on the left side is connected to the output shaft of the first servo motor 605 through a coupling.

[0034] See also Figure 1 and Figure 6 As shown, the positioning mechanism 7 includes a second slide bar 701, a positioning plate 702 and a second elastic member 703. The second slide bar 701 is slidably arranged on the upper left part of the mounting frame 2. The positioning plate 702 is welded to the bottom end of the second slide bar 701. The top of the positioning plate 702 is an inclined surface. The second elastic member 703 is connected between the top of the positioning plate 702 and the mounting frame 2. The second elastic member 703 is sleeved on the second slide bar 701.

[0035] When the device is to be used, the staff turns on the electric slotting machine 5 and the first servo motor 605, and the output shaft of the first servo motor 605 drives the roller 604 on the left to rotate. Then the staff places the PP plate on the mounting frame 2, and the staff pushes the PP plate to the right. The PP plate moves to the right and contacts the inclined surface at the top of the positioning plate 702. The PP plate squeezes the positioning plate 702 and moves upward. The second elastic member 703 is compressed accordingly, and the positioning plate 702 drives the second slide bar 701 to move upward. Under the action of the positioning plate 702, the PP plate can move straight to the right. When the PP plate moves to the right and contacts the inclined surface on the left side of the top of the mounting frame 602, the PP plate squeezes the mounting frame 602 and moves upward. The first elastic member 603 is compressed accordingly, and the mounting frame 602 drives the first slide bar 601 to move upward, so that the PP plate is pressed by the mounting frame 602. When the PP plate contacts the roller 604 on the left, the roller 604 on the left drives the PP plate to move right, and the PP plate moves right and contacts other rollers 604, thereby causing other rollers 604 to rotate and assist the PP plate to move right. When the PP plate contacts the blade of the electric slotting machine 5, the blade of the electric slotting machine 5 slots the bottom of the PP plate. When the PP plate is out of contact with the positioning plate 702, the second elastic member 703 is reset, driving the second slide bar 701 and the positioning plate 702 to move downward and reset. When the PP plate continues to move to the right to complete the slotting operation, the staff takes out the PP plate, and the first elastic member 603 is reset accordingly, driving the mounting frame 602 to move downward and reset. Repeating the above operation, the PP plate can be slotted again. When the device is no longer needed, the staff can turn off the electric slotting machine 5 and the first servo motor 605.

A torsion spring 905 is connected between the connecting plate 904 and the water pipe 802. The torsion spring 905 is sleeved on the front and rear parts of the first valve 804. The second top plate 906 is fixedly connected to the front and rear sides of the upper part of the first sliding rod 601. The right side of the lower part of the second top plate 906 is an inclined surface. The right side of the lower part of the second top plate 906 is an inclined surface in contact with the first top plate 903. A third elastic member 907 is connected between the left side of the first fixed block 901 and the first top plate 903. The third elastic member 907 is sleeved on the guide rod 902.

[0039] When the device is to be used, the staff connects the external pipe to the water pipe 802. Under the action of the sleeve 803, the external pipe can be better connected to the water pipe 802. When the first slide bar 601 moves upward, the first slide bar 601 drives the second top plate 906 to move upward, and the inclined surface on the right side of the lower part of the second top plate 906 squeezes the first top plate 903 to move rightward. The third elastic member 907 is compressed accordingly, and the first top plate 903 moves rightward to push the connecting plate 904 to rotate, and the torsion spring 905 is deformed accordingly, so that the water in the external water pipe enters the water pipe 802. The water in the water pipe 802 is sprayed out through the nozzle 801 to cool the blade of the electric slotting machine 5 to prevent the blade from being damaged by excessive temperature on the PP board. When the first slide bar 601 moves downward, the first slide bar 601 drives the second top plate 906 to move downward, and the third elastic member 907 is reset to drive the first top plate 903 to move leftward and reset. At the same time, the torsion spring 905 is reset to drive the first valve 804 and the connecting plate 904 to reverse and reset, thereby blocking the water pipe 802 again. When the device is not needed, the staff can disconnect the external water pipe from the water supply.

[0041] When the nozzle 801 sprays water to cool the blade of the electric slotting machine 5, the waste water can fall into the collecting sleeve 1001, and the waste water in the collecting sleeve 1001 is collected in the collecting box 1003 through the collecting pipe 1002. When the waste water in the collecting box 1003 needs to be discharged, the staff turns the second valve 1006 to unblock the outlet pipe 1004, and the waste water is discharged through the outlet pipe 1004. When the waste water is discharged, the staff reverses and resets the second valve 1006. In this way, the waste water can be better collected through the collecting sleeve 1001 and the collecting box 1003.

[0042] See also Figure 1 , Fig.11 and Fig.12 As shown, it also includes a transmission mechanism 11, which includes a guide plate 1101, a rotating shaft 1102, a pulley 1103, a flat belt 1104, a limit block 1105 and a second servo motor 1106.
