A roller 13 is fixedly connected to one side of the first cylinder 12. A bracket 14 is provided at the bottom of the connecting frame 6. A second cylinder 15 is fixedly connected to one side of the bracket 14. A positioning plate 16 is fixedly connected to one side of the second cylinder 15. The adjusting winding assembly further includes a first drive rod 17, one side of which is fixedly connected to the laying roller 2. An adjusting plate 18 is movably connected to the other side of the first drive rod 17. A second drive rod 19 is fixedly connected to one side of the winding roller 8. Gears 20 are fixedly connected to the surfaces of both the first drive rod 17 and the second drive rod 19. A fixing plate 21 is threadedly connected to the surface of the lead screw 9. One side of the fixing plate 21 is fixedly connected to the connecting frame 6. The adjusting plate 18... A slider is fixedly connected to one side, and the slider is slidably connected to the vertical plate 7. The second drive rod 19 is movably connected to the adjusting plate 18 on one side. Two gears 20 mesh with each other. The snap-fit ​​assembly also includes a limiting strip 22, which is located inside the slot 11. A through groove 23 is opened at the top of the limiting cylinder 10. A support plate 24 is provided at the bottom of the limiting strip 22. A spring 25 is fixedly connected to the bottom of the support plate 24. The bottom of the spring 25 is fixedly connected to the bottom of the inner part of the limiting cylinder 10. A battery is fixedly connected to one side inside the housing 3. A switch button is fixedly connected to the front of the housing 3. A knob is fixedly connected to the front of the lead screw 9. The output end of the motor 4 passes through the housing 3 and is fixedly connected to the limiting cylinder 10. The connecting bracket 6 is threadedly connected to the surface of the threaded rod 5. The bottom of the housing 3 is in contact with the bottom of the inner part of the door and window frame 1.

[0031] Specifically: the housing 3 is fixedly connected to the bracket 14, the back of the lead screw 9 is movably connected to the adjusting plate 18, a sliding groove adapted to the slider is opened on one side of the vertical plate 7, which can ensure that the adjusting plate 18 can move back and forth normally when the lead screw 9 rotates, the through groove 23 and the slot 11 are designed to intersect in a cross shape, which facilitates the limiting strip 22 to be limited while also allowing it to be disassembled, the top of the support plate 24 contacts the limiting strip 22, and the bottom of the threaded rod 5 passes through the limiting cylinder 10 and is fixedly connected to the limiting strip 22.

[0032] The working principle of this utility model is as follows: The adhesive sealing strip is pasted at the desired position on the door / window frame 1. The sealing strip is then fixed in place using a fixing device. The housing 3 is pressed tightly against the bottom inner side of the door / window frame 1. The second cylinder 15 operates, driving the positioning plate 16 to move, thus fixing the entire device onto the door / window frame 1. The first cylinder 12 operates, driving the roller 13 to move until it contacts the door / window frame 1, thereby limiting the connection frame 6. The sealing strip passes between the laying roller 2 and the take-up roller 8, and the release paper is wrapped and fixed to the surface of the take-up roller 8. By turning the knob on the screw 9, the adjusting plate 18 and all its components move backward, adjusting the distance between the laying roller 2 and the door / window frame 1. This allows the laying roller 2 to adjust the pressure applied to the sealing strip during installation. The motor 4 then drives the limiting cylinder 10 and threaded rod 5 to rotate as a whole. The rotation of the threaded rod 5 causes the connecting frame 6 and all its components to move downwards. The laying roller 2 then rolls and presses the sealing strip to secure it. Simultaneously, the rotation of the laying roller 2 drives the first drive rod 17 to rotate, which in turn drives the take-up roller 8 to rotate via the gear 20 and the second drive rod 19. The take-up roller 8 peels off the release paper and winds it up, ensuring proper installation and bonding with the laying roller 2. The entire process is fully automated, requiring no manual intervention. This highly efficient and convenient method ensures consistent pressure during each application, guaranteeing the sealing strip's effectiveness and extending its lifespan.

[0033] At the automated finishing touches, manual finishing touches and cutting of the sealing strips are required. When changing the sealing edge, the threaded rod 5 needs to be pressed down to move the limiting strip 22 out of the slot 11. At the same time, the spring 25 is pressed down by the support plate 24. When the limiting strip 22 has completely moved out of the slot 11, the limiting strip 22 is rotated 90 degrees. The spring 25 and the support plate 24 pop out the limiting strip 22 and the threaded rod 5, removing the original threaded rod 5. A matching threaded rod 5 is then replaced according to the size of the door and window frame 1. The above disassembly process is reversed to install the matching threaded rod 5. In this way, the sealing strips on all four sides of the door and window frame 1 can be quickly fixed.
