DETAILED DESCRIPTION

As shown in Figures 1-5, a thin plate leveling and striping shearing unit of the present invention includes a frame 1, an upper knife shaft 2 and a lower knife shaft 3 are arranged on the frame 1, and disc blade groups are sleeved on the upper knife shaft 2 and the lower knife shaft 3. The disc blade group of the upper knife shaft and the disc blade group of the lower knife shaft are staggered. The disc blade group includes a fixed disc blade 4 and a plurality of movable disc blades 5. An iron ring 6 fixedly connected to the movable disc blade 5 is arranged on one side of the movable disc blade 5. A cylinder 7 is arranged on one side of each movable disc blade 5. The cylinder 7 is connected to the frame 1 through a fixing mechanism, and an electromagnet 8 is arranged on the piston of the cylinder 7.

Specifically, the electromagnet 8 on the cylinder 7 is energized, and is attracted and fixed to the iron ring 6 on one side of the movable disc blade 5 on the upper cutter shaft. Through the controller, each cylinder 7 is controlled to move the movable disc blade 5 by the same distance, so as to achieve the purpose of adjusting the blade gap. After the adjustment is completed, the movable disc blade 5 is fixed to the cutter shaft by bolts. This method can also be used for the lower cutter shaft. After the adjustment is completed, the power is turned off to separate the cylinder 7 from the cutter shaft.

In order to allow the movable disc blade 5 of the upper cutter shaft 2 and the movable disc blade 5 of the lower cutter shaft 3 to be adjusted simultaneously, the iron ring 6 of the upper cutter shaft 2 can be connected to or disconnected from the iron ring 6 of the lower cutter shaft 3 through a connecting mechanism.

The connecting mechanism includes a connecting rod 9 arranged on the iron ring 6 of the upper knife shaft 2, and the connecting rod 9 is connected to the iron ring 6 by an elastic pad 10. A pressure rod 11 is provided at the bottom of the connecting rod 9, and a return spring 12 is provided on the upper end of the pressure rod 11, and a pressure block 13 is provided at the lower end. The pressure block 13 is arranged in a connecting sleeve 14, and a top block 15 is also provided in the connecting sleeve 14. The top block 15 fits with the inclined surface of the pressure block 13, and the top block 15 is connected to the pressure block 13 through a T-shaped slider 16 and a slide groove 17. A first socket 18 that cooperates with the top block 15 is provided on the iron ring 6 of the lower knife shaft 3.

Specifically, the pressure rod 11 is pressed, and the pressure block 13 pushes the top block 15 to be inserted into the first socket 18 of the lower cutter shaft 3, so that the movable disc blade 5 of the upper cutter shaft 2 and the movable disc blade 5 of the lower cutter shaft 3 are connected as a whole, and at the same time, the movable disc blade 5 on the lower cutter shaft 3 is driven to adjust the gap. This pressing structure can avoid interfering with the operation of the disc blade when there is no need to adjust the blade gap.

A connecting plate 19 is provided on the cylinder 7 , and a second socket 20 which cooperates with the top block 15 is provided on the connecting plate 19 .

It also includes a latch 24, which can fix the top block 15 to the iron ring 6 of the lower knife shaft 3 and the connecting plate 19, so as to make the connection more firm.

The fixing mechanism includes a pressing cylinder 21, which is connected to the frame 1 through a flat plate. The piston of the pressing cylinder 21 is connected to a pressing plate 22, which is slidably connected to the frame 1. The cylinder 7 is fixedly connected to the pressing plate 22 through a connecting rod 23. A drive box is provided at one end of the upper knife shaft 2 and a bearing is provided at the other end. The drive box and the bearing are slidably connected to the frame 1.

Specifically, the same method as above is used to rotate the connecting mechanism of the upper knife shaft 2 to connect with the cylinder 7 (1 to 2 cylinders 7 can be connected), and the cylinder 7 is adjusted up and down under the drive of the pressing cylinder 21, so that the distance between the upper knife shaft 2 and the lower knife shaft 3 can also be adjusted according to the thickness of the plate.

The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
