[0023] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.
[0024] like Figure 4 As shown, the automatic sealing strip shearing device includes a feed base 1, with a pressing chamber 12 and a clamping chamber 13 disposed at the front and rear ends of the feed base 1, respectively. A guide hole extending from front to back is provided within the feed base 1. The guide hole transversely passes through the pressing chamber 12 and the clamping chamber 13. The guide hole is used to guide the sealing strip A to be sheared. The sealing strip A enters the guide hole at the feed end, then transversely passes through the pressing chamber 12, then transversely passes through the clamping chamber 13, and emerges from the discharge end of the guide hole. The feed base 1 is fixed to a fixed base plate 21.
[0025] like Figure 1 As shown, a mounting base 2 is fixed to the feeding base 1. A sealing strip advancing mechanism is provided on the mounting base 2. The front end of the sealing strip advancing mechanism is connected to a sealing strip clamping mechanism, which is located in a clamping cavity 13. A pressing mechanism is provided on the mounting base 2, which is located in a pressing cavity 12. During operation, the sealing strip clamping mechanism can clamp the sealing strip A in the clamping cavity 13, and the sealing strip advancing mechanism can push the clamped sealing strip A forward. The pressing mechanism can also compress the sealing strip in the pressing cavity 12.
[0026] like Figure 2 and Figure 3 As shown, the sealing strip propulsion mechanism includes a propulsion cylinder seat 7 fixed on the mounting base 2 , a propulsion cylinder 6 is fixed on the propulsion cylinder seat 7 , and a driving end of the propulsion cylinder 6 is connected to the air clamp connecting plate 9 .
[0027] like Figure 2 and Figure 3 As shown, the lower end of the air clamp connecting plate 9 is connected to the slider 10, the slider 10 is slidably connected to the guide rail 8, and the guide rail 8 is fixed on the mounting base 2.
[0028] like Figure 2 and Figure 3As shown, a limit block 14 is fixed on the mounting base 2, and a limit bolt 15 is connected to the limit block 14 through a thread. The limit bolt 15 is located on the moving path of the air clamp connecting plate 9. The limit bolt 15 limits the air clamp connecting plate 9. The limit bolt 15 can be adjusted during use to adjust the limit position of the air clamp connecting plate 9.
[0029] like Figure 2 and Figure 3 As shown, the sealing strip clamping mechanism includes a connecting air clamp 11 vertically connected to the front lower end of the air clamp connecting plate 9. The air clamp 11 is located in a clamping cavity 13 and can clamp the sealing strip located in the clamping cavity 13. When the propulsion cylinder 6 is in operation, it can drive the air clamp connecting plate 9 to move back and forth. The air clamp connecting plate 9 in turn drives the air clamp 11 to move back and forth. The air clamp 11 can also drive the clamped sealing strip A to move back and forth.
[0030] like Figure 2 and Figure 3 As shown, the clamping mechanism includes a clamping cylinder base 3 fixed to the mounting base 2, a clamping cylinder 4 vertically mounted on the side of the clamping cylinder base 3 detachably connected by bolts, and a clamping plate 5 connected to the front end of the clamping cylinder 4. The clamping plate 5 is located in the clamping cavity 12. When the clamping cylinder 4 is in operation, it can push the clamping plate 5 to compress the sealing strip A in the clamping cavity 12.
[0031] like Figure 2 As shown, long strip-shaped bolt connection holes are respectively provided on both sides of the clamping cylinder 4 , and bolts are connected in the bolt connection holes. The bolts can be adjusted up and down along the bolt connection holes, thereby adjusting the height position of the clamping cylinder 4 .
[0032] like Figure 1 and Figure 5 As shown, a pneumatic scissors 16 is provided at the discharge end of the guide hole, and the pneumatic scissors 16 is connected to a scissor fixing bracket 17 by bolts.

When in use, the pneumatic scissors 16 can cut the sealing strip A extending from the discharge end of the guide hole.
[0034] The working principle of the present utility model is as follows: when cutting the sealing strip, first pass the sealing strip A coil through the material guide hole and send it to the position of the pneumatic scissors. The head of the sealing strip A exposed at the discharge end of the material guide hole is removed. The sealing strip A at this position is the zero position. Then, the air clamp 11 is activated to clamp the sealing strip A. Then, the propulsion cylinder 6 pushes the air clamp 11 forward to feed the sealing strip A forward until it is supported by the limit bolt 15. The limit bolt 15 can also adjust the length of the cut sealing strip. Then, the clamping cylinder 4 presses down to press the sealing strip A to prevent the sealing strip A from shifting and causing a deviation in the cutting length. The pneumatic scissors are activated to cut the protruding sealing strip A. Then, the air clamp 11 is released and the propulsion cylinder 6 is reset. This process is repeated to complete the batch cutting of the sealing strips A.
