Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 6 This utility model provides a specific technical implementation scheme based on a cutting device for the production of automotive sealing strips:

[0027] A cutting device for producing automotive sealing strips includes: a platform 1, a first vertical rod 2, a first round rod 3, a first roller 4, a second vertical rod 5, a second round rod 6, a second roller 7, a through-hole 8, a slide rod 9, a block 10, a spring 11, a third roller 12, a groove 13, a wheel 14, a cover 15, a stud 16, a threaded sleeve 17, a frame 18, a push rod 19, a rod 20, a cutter 21, and a motor 22; the platform 1 is fixedly connected to multiple first vertical rods 2 and second vertical rods 5, and the platform 1 is equipped with multiple first rollers 4. The second roller 7, a portion of the second roller 7, and all of the first roller 4 are connected to a first round rod 3. Multiple first round rods 3 are rotatably connected to corresponding first vertical rods 2 or second vertical rods 5, enabling flexible rotation of the first roller 4 and a portion of the second roller 7, facilitating the conveying of sealing strips. A portion of the second roller 7 is fixedly connected to the same second round rod 6, which is rotatably connected to a corresponding second vertical rod 5, allowing the second round rod 6 to drive the corresponding two second rollers 7 to rotate, facilitating the simultaneous conveying of two automotive sealing strips. Each vertical rod 5 has an opening 8, and multiple openings 8 are connected to sliding rods 9. Multiple sliding rods 9 are slidably connected to blocks 10. Every two sets of blocks 10 are rotatably connected to the same third roller 12. Multiple third rollers 12 are in contact with corresponding second rollers 7. Springs 11 are fitted on the surface of multiple sliding rods 9. Both the openings 8 and the blocks 10 are rectangular. In this way, after the blocks 10 are in contact with the openings 8, the blocks 10 cannot rotate and can only move in a stable lifting and lowering motion. The elasticity of the springs 11 keeps the third rollers 12 always in contact with the second rollers. 7. Maintain appropriate pressure to tighten and stabilize the sealing strip during transport, effectively preventing the sealing strip from shifting or loosening during transport. One end of multiple springs 11 is connected to the corresponding second vertical rod 5 and block 10, respectively. The platform 1 is fixedly connected to the frame 18. The coordinated action of multiple first rollers 4, second rollers 7 and third rollers 12, combined with the clamping force of the springs 11 and the annular groove design, effectively prevents the sealing strip from shifting or loosening during transport, ensuring cutting accuracy and improving product qualification rate.

[0028] Each of the multiple first vertical rods 2 has a groove 13, and each of the multiple first vertical rods 2 has a cover 15 placed on its top. The multiple grooves 13 and the cover 15 are rotatably connected to multiple wheels 14. Each of the multiple first vertical rods 2 is connected to two studs 16. The multiple studs 16 pass through the holes of the corresponding cover 15. The multiple studs 16 are threadedly connected to threaded sleeves 17. The multiple threaded sleeves 17 are in contact with the corresponding cover 15. By rotating the threaded sleeves 17, the position of the cover 15 can be easily adjusted, thereby adjusting the contact between the wheels 14 and the shafts of different diameters on both sides of the winding roller that winds up the automotive sealing strip.

[0029] Multiple first rollers 4 and second rollers 7 are rollers with annular grooves. A motor 22 is installed at a second vertical rod 5 and is connected to a second round rod 6. This allows the motor 22 to rotate multiple second rollers 7 using the second round rod 6, facilitating the cutting and conveying of two automotive sealing strips by one motor 22.

[0030] A push rod 19 is installed through the frame 18. A rod body 20 is provided at the output end of the push rod 19. A blade body 21 is provided at one end and the other end of the rod body 20. Multiple blade bodies 21 are respectively placed corresponding to the second roller body 7. When the push rod 19 pushes the rod body 20 to move, the blade body 21 can cut the sealing strip located on the second roller body 7.

[0031] The rod body 20 is threadedly connected to the output end of the push rod 19, which facilitates the assembly and disassembly of the rod body 20.

[0032] The rod 20 is connected to the cutter body 21 by bolts, which facilitates the installation and replacement of the cutter body 21.

[0033] Multiple wheel bodies 14 are rubber wheels; rubber wheels have good friction and flexibility, which can better fit the sealing strip, further assist in conveying the sealing strip and prevent its surface from being damaged.

[0034] Specifically, there are no restrictions on the model and specifications of the push rod 19 and the motor 22, as long as they meet the usage requirements. Both the push rod 19 and the motor 22 are controlled by external power supply and external drive device, and can be selected according to the requirements.

[0035] Specific implementation steps

[0036] Place the take-up roller containing the automotive sealing strip into the grooves 13 corresponding to the two first vertical rods 2, so that the shafts at one and the other ends of the take-up roller can contact the wheel 14 in the grooves 13 corresponding to the first vertical rods 2. After contact, insert the cover 15 into the corresponding stud 16, and make the wheel 14 of the cover 15 contact the shaft of the take-up roller wound with the automotive sealing strip. After contact is completed, thread the threaded sleeve 17 to the stud 16 to fix the cover 15. After fixing, place the automotive sealing strip on the take-up roller wound with the automotive sealing strip. The strip is placed in a serpentine pattern at the corresponding first roller 4 and second roller 7. After completion, the corresponding second roller 7 and third roller 12 can press one end of the car sealing strip. In this way, when the motor 22 is connected to an external power supply and control device, it can stably drive the car sealing strip to move. When the car sealing strip moves, the push rod 19 is connected to an external power supply and control device, and the cutter body 21 is moved back and forth. The cutter body 21 continuously cuts the car sealing strip conveyed by the second roller 7, thus performing the cutting operation on the car sealing strip.

[0037] In summary, this cutting equipment for automotive sealing strip production utilizes a platform with first and second vertical rods, along with first, second, and third rollers, to arrange the sealing strip in a serpentine pattern. The clamping action of the second and third rollers at the ends eliminates offset and slack during transport, ensuring precise cutting positioning. Simultaneously, the stable clamping state allows the cutter to smoothly cut the sealing strip, avoiding uneven cross-sections and high scrap rates caused by displacement. Furthermore, the grooves and wheels on the first vertical rod, combined with the cover, stud, and threaded sleeve, enable rapid loading and unloading of the take-up roller: after embedding the shafts on both sides of the take-up roller into the grooves, the cover is fixed by screwing the threaded sleeve onto the stud, and the wheel and cover form a ring-like clamp, ensuring stable and offset-free winding. Disassembly simply requires loosening the threaded sleeve in the reverse direction to easily remove the cover and replace the roller, significantly improving the ease of operation and production efficiency of the winding process, thus effectively solving the problems and shortcomings of existing devices.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
