[0015] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] See Figure 1-3 As shown in the figure, this application discloses a car trunk sealing strip cutting mechanism, including a support base 1, a vertical plate 2, a movable plate 3, a cylinder 4, a blade assembly 5, and two support blocks 6. The vertical plate 2 is fixed to the top of the front end of the support base 1, the cylinder 4 is fixed to the top of the rear end of the support base 1, and the movable plate 3 is movably disposed between the vertical plate 2 and the cylinder 4. The movable plate 3 is connected to the piston rod of the cylinder 4. The blade assembly 5 includes a fixed blade 51 and a movable blade 52 that fit together. The front end of the fixed blade 51 is fixed to the rear side of the vertical plate 2, and the rear end of the movable blade 52 is fixed to the front side of the movable plate 3. The cylinder 4 is used to drive the movable plate 3 to move back and forth so that the movable blade 52 moves back and forth relative to the fixed blade 51. The two support blocks 6 are symmetrically disposed on both sides of the blade assembly 5. The rear sides of both support blocks 6 are fixed to the movable plate 3. Each support block 6 is provided with a contoured hole 61 for the trunk sealing strip to pass through. The shape of the contoured hole 61 is adapted to the outer contour of the trunk sealing strip.

[0017] The lower end of the movable plate 3 abuts against the support base 1 and can move back and forth relative to the support base 1. With this structure, when the movable plate is driven to move back and forth by the cylinder, the movement of the movable plate is smoother and more stable because the lower end of the movable plate abuts against the support base and can move back and forth relative to the support base.

[0018] Two symmetrical guide components 7 are provided between the movable plate 3 and the vertical plate 2. Each guide component 7 includes a guide sleeve 71 and a guide post 72. The front end of the guide sleeve 71 is fixed to the rear side of the vertical plate 2, and the rear end of the guide post 72 is fixed to the front side of the movable plate 3. The front end of the guide post 72 is inserted into the rear end of the guide sleeve 71, and the guide post 72 and the guide sleeve 71 are slidably connected back and forth. With this structure, when the movable plate is driven to move back and forth by the cylinder, the reliability and stability of the movable plate relative to the vertical plate can be further improved by the cooperation of the guide sleeve and the guide post, that is, the movement of the movable plate can be made smoother and more stable.

[0019] Each support block 6 is fixed to the front side of the movable plate 3 by two support rods 62 that are spaced apart vertically; with this structure, each support block can be reliably fixed to the front side of the movable plate by the support rods and can move back and forth with the movable plate.

[0020] When using this invention to cut a car trunk sealing strip, the sealing strip passes through a contour hole on a support block located on one side of the blade assembly and exits through a contour hole on a support block located on the other side of the blade assembly. When the control cylinder drives the movable plate forward, the moving blade moves forward relative to the fixed blade. At this time, with the cooperation of the moving and fixed blades, the sealing strip between the two support blocks can be cut. After cutting, the cylinder drives the movable plate to move backward and reset. At this time, the fixed blade also moves backward and resets with the movable plate. In the above process, the contour hole on the support block can support the sealing strip and limit its vertical and horizontal movement, ensuring that the moving and fixed blades can reliably cut the sealing strip.

[0021] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
