Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1-5 , a quantitative cutting device for sealing strips, comprising a vertical support plate 1, a driving wheel 2 is provided at one end of one side of the vertical support plate 1, a driven wheel 3 is provided on the top of the driving wheel 2, a U-shaped support frame 4 is fixed to one side of the vertical support plate 1, a plurality of longitudinal driven rollers 5 are evenly distributed inside the U-shaped support frame 4, a first vertical hydraulic cylinder 8 is provided on the top of the U-shaped support frame 4, an arc-shaped fixed block 9 is fixed to the outside of the first vertical hydraulic cylinder 8, the arc-shaped fixed block 9 is close to one side of the vertical support plate 1 and is fixedly connected to the vertical support plate 1, a vertical lifting plate 7 is fixed to the output end of the first vertical hydraulic cylinder 8, a vertical cutting knife 6 is fixed to the bottom of the vertical lifting plate 7, both ends of the vertical cutting knife 6 are provided with a liftable rectangular limit block 10, and the other side of the vertical support plate 1 is provided with a lifting mechanism for lifting the rectangular limit block 10;

[0021] A first drive motor 11 is fixed to the other side of the vertical support plate 1 by bolts. The output end of the first drive motor 11 is fixedly connected to the driving wheel 2. The operation of the first drive motor 11 enables the driving wheel 2 to rotate, and the rotation of the driving wheel 2 enables the sealing strip to be moved.

[0022] A second vertical hydraulic cylinder 12 is provided on the other side of the vertical support plate 1 and at one end of the first drive motor 11. A second vertical hydraulic cylinder 12 is fixed to the output end of the second vertical hydraulic cylinder 12. A longitudinal connecting rod 14 is fixed to one end of the second vertical hydraulic cylinder 12. The longitudinal connecting rod 14 passes through the interior of the driven wheel 3 and is rotatably connected to the driven wheel 3 through a bearing. The longitudinal connecting rod 14 is located inside the vertical support plate 1 and is slidably connected to the vertical support plate 1. Through the operation of the second vertical hydraulic cylinder 12, the longitudinal connecting rod 14 can be vertically lifted and lowered so that the driven wheel 3 moves toward the driving wheel 2, thereby adjusting the distance between the driving wheel 2 and the driven wheel 3;

[0023] Here, through the operation of the second vertical hydraulic cylinder 12, the vertical lifting column 13 can be vertically lifted and lowered. The lifting of the vertical lifting column 13 enables the longitudinal connecting rod 14 to be vertically lifted and lowered inside the vertical support plate 1, thereby enabling the rubber strip to be located between the driving wheel 2 and the driven wheel 3. Through the operation of the first drive motor 11, the rubber strip can be moved laterally. Through the operation of the first drive motor 11, the moving distance of the rubber strip can be calculated to facilitate the quantitative measurement of the rubber strip. Through the operation of the first vertical hydraulic cylinder 8, the vertical lifting plate 7 can be vertically lifted and lowered. The vertical lifting of the vertical lifting plate 7 enables the vertical cutting knife 6 to be vertically lifted and lowered. The descent of the vertical cutting knife 6 enables the rubber strip to be cut at the top of the U-shaped support frame 4.

[0024] The lifting mechanism includes a U-shaped mounting plate 15, which is close to one side of the vertical support plate 1 and fixedly connected to the vertical support plate 1. One end of the U-shaped mounting plate 15 is bolted to a second drive motor 16, and a first transverse threaded rod 17 is fixed to the output end of the second drive motor 16. A second transverse threaded rod 18 is fixed to the end of the first transverse threaded rod 17 away from the second drive motor 16. The thread rotation direction of the first transverse threaded rod 17 and the second transverse threaded rod 18 are opposite. The outer sides of the first transverse threaded rod 17 and the second transverse threaded rod 18 are both threadedly connected to a transverse rectangular slider 19, and the top of the transverse rectangular slider 19 is rotatably connected to an oblique rotating column 20 through a pin shaft. The top of the oblique rotating column 20 is rotatably connected to a transverse mounting plate 21 through a pin shaft. L-shaped lifting columns 22 are fixed to both ends of the top of the transverse mounting plate 21, and the bottom of one side of the L-shaped lifting column 22 is fixedly connected to the rectangular limit block 10;

[0025] A dovetail slider is fixed to the bottom of the transverse rectangular slider 19, and a dovetail slot is provided inside the U-shaped mounting plate 15. The transverse rectangular slider 19 and the U-shaped mounting plate 15 are slidably connected by the cooperation of the dovetail slider and the dovetail slot. The cooperation of the dovetail slider and the dovetail slot enables the transverse rectangular slider 19 to slide horizontally inside the U-shaped mounting plate 15.

[0026] A vertical slide groove is provided inside the vertical support plate 1. The L-shaped lifting column 22 is located inside the vertical slide groove and is slidably connected to the vertical support plate 1 through the vertical slide groove. The vertical slide groove is provided so that the L-shaped lifting column 22 can slide vertically inside the vertical support plate 1.

[0027] Here, the operation of the second drive motor 16 enables the first transverse threaded rod 17 and the second transverse threaded rod 18 to rotate. The rotation of the first transverse threaded rod 17 and the second transverse threaded rod 18 enables the transverse rectangular slider 19 to slide transversely inside the U-shaped mounting plate 15. The sliding of the transverse rectangular slider 19 enables the transverse mounting plate 21 to be raised and lowered through the oblique rotating column 20. The vertical lifting of the transverse mounting plate 21 enables the rectangular limit block 10 to be raised and lowered vertically through the L-shaped lifting column 22, so that the rectangular limit block 10 can fix the rubber strip on the top of the U-shaped support frame 4, which is convenient for cutting by the vertical cutting knife 6, thereby avoiding poor cutting due to vibration or deviation generated during the transportation process.

[0028] Working principle: Through the operation of the second vertical hydraulic cylinder 12, the vertical lifting column 13 can be vertically lifted and lowered. The lifting of the vertical lifting column 13 enables the longitudinal connecting rod 14 to be vertically lifted and lowered inside the vertical support plate 1, thereby enabling the rubber strip to be located between the active wheel 2 and the driven wheel 3. Through the operation of the first drive motor 11, the rubber strip can be moved laterally. Through the operation of the first drive motor 11, the moving distance of the rubber strip can be calculated to facilitate the quantitative measurement of the rubber strip. Through the operation of the first vertical hydraulic cylinder 8, the vertical lifting plate 7 can be vertically lifted and lowered. The vertical lifting of the vertical lifting plate 7 enables the vertical cutting knife 6 to be vertically lifted and lowered. The descent of the vertical cutting knife 6 enables the rubber strip to be cut at the top of the U-shaped support frame 4.

[0029] The operation of the second drive motor 16 enables the first transverse threaded rod 17 and the second transverse threaded rod 18 to rotate. The rotation of the first transverse threaded rod 17 and the second transverse threaded rod 18 enables the transverse rectangular slider 19 to slide transversely inside the U-shaped mounting plate 15. The sliding of the transverse rectangular slider 19 enables the transverse mounting plate 21 to be raised and lowered through the oblique rotating column 20. The vertical lifting of the transverse mounting plate 21 enables the rectangular limit block 10 to be raised and lowered vertically through the L-shaped lifting column 22, so that the rectangular limit block 10 can fix the rubber strip on the top of the U-shaped support frame 4, which is convenient for cutting by the vertical cutting knife 6, thereby avoiding poor cutting due to vibration or deviation generated during the transportation process.
