[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 An automatic change reel guide strip conveying device, comprising a frame 1, two groups of transmission rollers 7 are rotatably connected to the inner wall of the frame 1, the two groups of transmission rollers 7 are connected to each other through a transmission belt 2, the outer wall of each of the two groups of transmission rollers 7 is provided with a guide groove 14, a guide strip 8 is installed on the inner wall of the transmission belt 2 and is embedded in the guide groove 14, two groups of limiting plates 9 are movably connected in the guide groove 14 and are located on the two sides of the guide strip 8 respectively, the cross section of the guide strip 8 is T-shaped, the cross section of the limiting plate 9 is L-shaped, the L-shaped cross section of the two groups of limiting plates 9 is tightly attached to the horizontal outer wall of the T-shaped cross section of the guide strip 8 through the vertical arm thereof, and the vertical arm of the L-shaped limiting plate 9 extends below the longitudinal outer wall of the T-shaped cross section of the guide strip 8, the top of the guide strip 8 is slightly higher than the vertical surface of the limiting plate 9, a plurality of sliding grooves 10 are formed in the outer wall of the transmission roller 7, and each of the plurality of sliding grooves 10 is arranged on the two sides of the guide groove 14, and a compensation assembly for tightly attaching the limiting plate 9 to the outer wall of the guide strip 8 is installed in each of the sliding grooves 10;

[0023] Further, the T-shaped guide strip 8 and the L-shaped limiting plate 9 are clamped, which can effectively limit the transverse displacement of the transmission belt 2 at high speed or sudden load change, and the vertical arm of the L-shaped limiting plate 9 extends below the longitudinal outer wall of the guide strip 8, forming a double limiting structure, which further improves the anti-deviation ability of the transmission belt 2, and the plurality of sliding grooves 10 and the compensation assembly can realize dynamic pressure compensation between the limiting plate 9 and the guide strip 8.

[0024] The compensation assembly comprises a fixed sleeve 11 which is slidably connected in the sliding groove 10, the fixed sleeve 11 slidably extends into the guide groove 14 and is fixedly connected to the outer wall of the adjacent limiting plate 9, a connecting rod 12 is fixedly connected to the inner wall of the sliding groove 10, the fixed sleeve 11 is slidably connected to the outer wall of the connecting rod 12, a lever is fixedly connected to the outer wall of the fixed sleeve 11 and the end face curvature thereof matches the curvature of the outer wall of the transmission roller 7, a spring 13 is installed in the fixed sleeve 11, one end of the spring 13 is fixedly connected to the bottom of the fixed sleeve 11, and the other end of the spring 13 is fixedly connected to the end of the connecting rod 12;

[0025] Further, the connecting rod 12 provides a stable sliding path for the fixing sleeve 11, preventing the fixing sleeve 11 from being deflected or stuck in the sliding groove 10, and the spring 13 continuously provides a pressing force for the fixing sleeve 11 and the limiting plate 9 through elastic deformation, ensuring that the limiting plate 9 is closely attached to the guide strip 8, even when the transmission belt 2 is slightly deformed due to long-term use, the stable limiting effect can still be maintained.

[0026] The frame 1 is fixedly connected with a support 4, the support 4 is externally connected with an electric telescopic rod 5, the electric telescopic rod 5 is fixedly connected with a tension pulley 6 at the telescopic end, and the tension pulley 6 is in contact with the outer wall of the transmission belt 2, the frame 1 is fixedly connected with a servo motor 3, and the output shaft of the servo motor 3 is coaxially fixedly connected with a transmission roller 7;

[0028] In the utility model, when the device is used, the operator starts the servo motor 3 to drive the transmission roller 7 to rotate, and drives the transmission belt 2 to run stably along the track of the guide groove 14. At this time, the T-shaped guide strip 8 on the inner wall of the transmission belt 2 is embedded in the guide groove 14 of the transmission roller 7, and forms a double limiting structure through the L-shaped limiting plate 9 on both sides, effectively inhibiting the lateral deviation of the transmission belt 2 when the transmission belt 2 is at high speed or the load suddenly changes, and ensuring the stability of the coiled material transmission path.

[0030] When the load frequently changes or the transmission belt 2 is relaxed, the electric telescopic rod 5 drives the tension pulley 6 to adjust the tension of the transmission belt 2 in real time. The tension pulley 6 is in contact with the outer wall of the transmission belt 2, disperses the local stress, and avoids slipping or vibration caused by uneven tension.

[0031] In summary, the device solves the problem of slippage caused by the wear of the traditional transmission belt through the clamping structure of the T-shaped guide strip 8 and the L-shaped limiting plate 9, the dynamic compensation mechanism of the spring 13 and the intelligent adjustment of the electric tension pulley 6.
