[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3A PVC profile positioning and cutting device includes a frame 1, with multiple sets of rotating rollers 5 rotatably connected inside the frame 1. A fixed frame 2 and two sets of side plates 4 are fixedly connected to the upper end of the frame 1. The fixed frame 2 is connected to a cutting blade 7 via a telescopic mechanism. A double-headed threaded rod 8 is rotatably connected between the two sets of side plates 4, and two sets of sliders 10 are threadedly connected to the threaded section of the double-headed threaded rod 8. A bracket 12 is fixedly connected to the outer walls of both sides of the slider 10. A slide rod 15 is slidably connected to the outer wall of the bracket 12. A frame plate 13 is fixedly connected to the end of the slide rod 15. Multiple sets of pulleys 14 are rotatably connected inside the frame plate 13. A buffer mechanism is installed on the outer wall of the slide rod 15. The buffer mechanism includes a spring 17 sleeved on the outer wall of the slide rod 15. A limit block 16 is fixedly connected to the end of the slide rod 15. One end of the spring 17 is fixedly connected to the bracket 12, and the other end of the spring 17 is fixedly connected to the limit block 16.

[0021] Specifically, the pulley 14 is made of rubber, which is flexible and elastic, allowing for flexible contact with the PVC profile surface and avoiding scratches or indentations caused by hard contact. Simultaneously, the spring 17 absorbs some of the impact force, further reducing pressure on the profile and preventing indentations.

[0022] The telescopic mechanism includes an electric telescopic rod 3 fixedly connected to the end face of the fixed frame 2. The telescopic end of the electric telescopic rod 3 passes through the fixed frame 2 and is connected to the cutting blade 7. A limit rod 9 is fixedly connected between the two sets of side plates 4. Both sets of sliders 10 are slidably connected to the outer wall of the limit rod 9. A base plate 6 is fixedly connected directly below the fixed frame 2. The radius of the limit block 16 is larger than the radius of the slider 15. A servo motor 11 is fixedly connected to the outer wall of one set of side plates 4. The output shaft end of the servo motor 11 is coaxially fixedly connected to the double-threaded rod 8.

[0023] Specifically, the electric telescopic rod 3 serves as the driving mechanism, which can precisely control the lifting and lowering of the cutting blade 7 to achieve automated segmented cutting.

[0024] In this utility model, when the device is used, the PVC profile is conveyed by multiple sets of rotating rollers 5 inside the frame 1. At this time, the cutting blade 7 is in the initial position under the action of the electric telescopic rod 3, maintaining a certain gap with the PVC profile to avoid unnecessary damage to the profile during the conveying process.

[0025] When the PVC profile is moved to the position requiring cutting, the operator activates the servo motor 11, which drives the double-ended threaded rod 8 to rotate. The two sets of sliders 10 on the double-ended threaded rod 8 move synchronously under the guidance of the limiting rod 9, causing the bracket 12 and slide bar 15 to adjust their positions. The pulley 14 can achieve flexible contact with the surface of the PVC profile. Under the action of the spring 17, the pulley 14 can adapt to the shape of the profile, avoiding scratches or indentations caused by hard contact. At the same time, the spring 17 absorbs some of the impact force, further reducing the pressure on the profile and ensuring the stability and accuracy of the limiting process.

[0026] After the limit is reached, the operator activates the electric telescopic rod 3, which slowly lowers the cutting blade 7 to contact the PVC profile and begin cutting. Precise control of the electric telescopic rod 3 ensures smooth lifting and lowering of the cutting blade 7, avoiding cutting errors caused by manual operation. During cutting, the base plate 6 provides stable support for the PVC profile, preventing it from shaking or shifting during cutting and ensuring cutting accuracy.

[0027] During the cutting process, the flexible contact between the pulley 14 and the PVC profile, along with the buffering effect of the spring 17, further reduces the impact force on the profile during cutting, preventing indentations or damage to the profile surface. Simultaneously, the cooperation between the servo motor 11 and the double-threaded rod 8 enables the limiting mechanism to adjust its position quickly and accurately, adapting to PVC profiles of different widths and shapes, thus improving the versatility and production efficiency of the device.

[0028] After cutting, the electric telescopic rod 3 drives the cutting blade 7 to reset, and the servo motor 11 drives the double-headed threaded rod 8 to adjust the limiting mechanism to its initial position, preparing for the next cutting operation. The fully automated design of the device reduces manual intervention, improves production efficiency, and avoids damage to the profiles due to operational errors.

[0029] In summary, this PVC profile positioning and cutting device achieves precise positioning and efficient cutting of PVC profiles through the coordinated operation of components such as the electric telescopic rod 3, servo motor 11, double-threaded rod 8, pulley 14, and spring 17. The device employs a flexible limiting and buffering design, effectively avoiding surface damage to the profiles caused by hard contact.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
