A slide bar 12 is fixedly connected to the connecting rod 7. A sleeve 13 is sleeved on the slide bar 12. A chute 14 is opened on the supporting plate 11. The sleeve 13 slides in the chute 14. The design of the supporting plate 11 and its linkage mechanism with the pulling block 9, the chute 14, the sleeve 13 and the slide bar 12 make the installation, fixation and expansion process of the roller shaft 15 fast and simple, further improving the operation convenience and production efficiency.

[0030] A conveying table 16 is fixedly connected to the base 1. A flattening roller frame 17 is fixedly connected to the conveying table 16. A roller shaft 18 is rotatably connected to the flattening roller frame 17. There are two groups of roller shafts 18 and they are vertically symmetrically distributed on the flattening roller frame 17. One end of the conveying table 16 away from the flattening roller frame 17 is fixedly connected to a connecting frame 19. A cylinder 20 is fixedly installed on the connecting frame 19. The output end of the cylinder 20 is fixedly connected to a cutting knife 21. A guide rod 22 is slidably connected to the connecting frame 19. One end of the guide rod 22 is fixedly connected to the cutting knife 21. A guide knife groove 23 is fixedly connected to the conveying table 16. The driving worm 4, the driven worm gear 5 and the rotating shaft 6 all rotate in the support base 2. There are multiple groups of connecting strips 10 and support plates 11. There are two groups of flattening roller frames 17. The two groups of flattening roller frames 17 are evenly distributed on the conveying table 16. There are two groups of guide rods 22 and they are evenly distributed on both sides of the cylinder 20. A groove adapted to the cutting knife 21 is formed in the guide knife groove 23. The guide knife groove 23 is located directly below the cutting knife 21. The shape of the support plate 11 is arc-shaped. The roller shaft 15 is in contact with multiple groups of support plates 11. This device integrates automated components such as the electric push rod 8, the motor 3 and the cylinder 20, realizes the automatic winding and cutting of the insulating shielding tape, greatly improves the production efficiency, and at the same time reduces the complexity of manual operation and the labor intensity.

[0031] Working principle: When using the production device of the plastic insulating shielding tape for electrified railways, first, start the electric push rod 8. The electric push rod 8 starts to work and pulls the pulling block 9 backward. The pulling block 9 is connected to the supporting plate 11 through multiple connecting bars 10. Therefore, the backward movement of the pulling block 9 will be transmitted to the supporting plate 11, causing the supporting plate 11 to also move backward. A sliding groove 14 is designed on the supporting plate 11, and a sleeve 13 is slidably connected in the sliding groove 14. The sleeve 13 is sleeved on the fixed sliding rod 12. This special design enables the supporting plate 11 to descend along the track of the sliding groove 14 on the sliding rod 12 while moving backward. Finally, multiple groups of supporting plates 11 will all descend and fit on the surface of the connecting rod 7, forming a space suitable for installing the roller 15. The roller 15 is sleeved on multiple groups of the already descended supporting plates 11, preparing for the next operation. Start the electric push rod 8 again to make it change direction and push the pulling block 9 forward. The forward movement of the pulling block 9 will be transmitted to the supporting plate 11 through the connecting bar 10, causing the supporting plate 11 to also move forward, expanding multiple groups of supporting plates 11, thereby lifting and fixing the roller 15. Manually pass one end of the insulating shielding tape through between the two rollers 18, ensuring it is flat and in the correct position. Then, pass the other end of the insulating shielding tape through between the cutting knife 21 and the guiding knife groove 23 to prepare for subsequent cutting. Wind the insulating shielding tape around the already lifted roller 15 and start the winding process. Start the motor 3. The motor 3 starts to work and drives the driven worm gear 5 to rotate through the driving worm 4. The rotation of the driven worm gear 5 will be transmitted to the rotating shaft 6, causing the rotating shaft 6 to also start to rotate. The rotation of the rotating shaft 6 will drive the connecting rod 7 and the roller 15 on the supporting plate 11 to rotate together, thereby realizing the winding of the insulating shielding tape on the roller 15. When the insulating shielding tape is wound to the predetermined length or completed, start the cylinder 20. The two guide rods 22 will ensure that the cutting knife 21 descends more smoothly and accurately. The cutting knife 21 will finally fall into the guiding knife groove 23 directly below to cut off the excess insulating shielding tape, completing the entire winding and cutting process.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
