[0030] Please see Figures 1-5 A protective device for an upward-adjusting idler support includes a frame 1 and an upward-adjusting idler frame 2. A rotating column 3 is rotatably connected to the frame 1. The bottom end of the rotating column 3 is connected to a base plate 21 by two second screws 20. The top end of the base plate 21 contacts the bottom end of the frame 1, which limits the bottom of the rotating column 3 and prevents the rotating column 3 from moving upward. The bottom end of the upward-adjusting idler frame 2 is fixedly connected to the top end of the rotating column 3. Support ring seats 4 are fixedly connected to both sides of the top end of the frame 1 on the rotating column 3. Each of the two support ring seats 4 has a support ring groove 5 at its top end. Two connecting plates 6 are fixedly connected to the bottom end of the upward-adjusting idler frame 2. Support ring bars 7 are fixedly connected to the bottom end of the two connecting plates 6. The central axis of the support ring bars 7 is on the same straight line as the central axis of the rotating column 3. The two support ring bars 7 are slidably engaged with the two support ring grooves 5 respectively. A locking mechanism is fixedly connected to the upward-adjusting idler frame 2.

[0031] Specifically, the combination of the support ring seat 4, the support plate and the support ring bar 7 can provide support and protection for the bottom two sides of the eccentric roller frame 2, improve the stability of the support for the eccentric roller frame 2, extend the service life of the eccentric roller frame 2, reduce the failure rate of the eccentric roller frame 2, and at the same time enable the corresponding angle adjustment.

[0032] Please see Figures 3-5The locking mechanism includes a fixed base 8, which is fixedly connected to the frame 1. A screw 9 is threaded onto the fixed base 8, and a locking pin 10 is fixedly connected to the side end of the screw 9. The inner diameter of the screw 9 is larger than the outer diameter of the locking pin 10, so that the locking pin 10 can be pulled out from the threaded hole that mates with the screw 9. Multiple locking grooves 11 that are adapted to the locking pin 10 are evenly arranged on the outer wall of the support ring seat 4, so as to facilitate the fixing of the adjustment roller frame 2. A throttle 12 is fixedly connected to the side end of the screw 9, so as to facilitate the rotation of the screw 9. A fixing block 13 is fixedly connected to the side end of the fixed base 8, and an adjustment groove 14 is provided on the fixing block 13. The inner diameter of the adjustment groove 14 is larger than the outer diameter of the locking pin 10, so that the locking pin 10 can be pulled out from the threaded hole that mates with the screw 9. A limiting plate 15 is slidably provided in the part, and a pull rod 16 is fixedly connected to the side end of the limiting plate 15. The pull rod 16 is slidably engaged with the fixing block 13. A compression spring 17 is sleeved on the outside of the pull rod 16. The pull rod 16 is located inside the adjusting groove 14, which facilitates the positioning of the handle 12 and prevents the handle 12 from moving relative to the fixing seat 8, thereby preventing the handle 12 and the screw 9 from loosening. A handle 18 is detachably connected to one end of the pull rod 16 that extends to the outside of the fixing block 13, which facilitates the movement of the pull rod 16. The handle 18 is connected to the fixing block 13 through the first screw 19, which facilitates the disassembly and assembly of the handle 18 and the replacement of the compression spring 17.

[0033] Specifically, by rotating the screw 9, the screw 9 moves relative to the fixed seat 8, causing the locking pin 10 to be inserted into the corresponding slot 11. This facilitates the fixing of the fixed seat 8 and the eccentric roller frame 2, preventing the eccentric roller frame 2 from rotating and improving the stability of the eccentric roller frame 2. After the locking pin 10 is fully inserted into the slot 11, the compression spring 17 pushes the limiting plate 15 to move, causing the limiting plate 15 to move to the position corresponding to the throttle 12. The limiting plate 15 blocks the throttle 12, preventing the screw 9 and the throttle 12 from moving relative to the fixed seat 8, thereby preventing the screw 9 from rotating relative to the fixed block 13 and thus preventing the screw 9 from loosening.

[0034] In summary, when using the overall equipment:

[0035] Pulling the lever 18 moves the lever 16 and the limiting plate 15, separating the limiting plate 15 from the handle 12. Simultaneously, rotating the handle 12 counterclockwise and the screw 9 moves the screw 9 away from the fixed seat 8, separating the locking pin 10 from the locking groove 11. Then, the support ring 7 rotates inside the support ring groove 5 to adjust the alignment of the roller frame 2. After adjustment, pulling the lever 18 again moves the lever 16 and the limiting plate 15, separating the limiting plate 15 from the fixed seat 4. There is a side that is always away from the screw 9. At the same time, by rotating the handle 12 and the screw 9 clockwise, the screw 9 moves relative to the fixed seat 8 towards the side closer to the support ring seat 4, so that the locking pin 10 is fully inserted into the corresponding locking groove 11. Then, the pull handle 18 is released, and the limiting plate 15 is pushed to move by the compression spring 17, so that the limiting plate 15 moves to one side of the handle 12. At this time, the side end of the limiting plate 15 contacts the side end of the handle 12, thereby completing the adjustment operation of the adjustment roller frame 2.
