Description
Technical Field
[0001] This utility model relates to the technical field of metal heat treatment equipment, specifically to a strip winding angle self-feedback rudder roller device applied to a coil annealing furnace. Background Technology
[0002] Traditional metal sheet annealing furnaces are mostly offline, with separate annealing equipment or continuous annealing production lines. The coiler is open and only has winding and unwinding functions, without heat preservation. A lot of heat is lost during the production process, wasting energy. Due to repeated temperature changes of the sheet and strip, stress cracking can occur, resulting in a decrease in sheet and strip quality and a decrease in yield.
[0003] Existing technologies often employ servo motors to drive the furnace shell rotation. For example, Chinese Patent 20181023567.X discloses an annealing furnace opening angle adjustment device, which uses a photoelectric sensor to detect the position of the strip and then drives an electric push rod to adjust the furnace body angle. However, such solutions suffer from problems such as complex control systems and high maintenance costs.
[0004] Therefore, it is necessary to develop a self-feedback rudder roller device for the strip winding angle that can overcome the above-mentioned shortcomings and be applied to a coil annealing furnace. Summary of the Invention
[0005] To address the problems existing in the prior art, this utility model provides an online coil annealing furnace, specifically a self-feedback rudder roller device for the strip winding angle within the furnace. This furnace combines online winding, online unwinding, strip coil heat preservation, strip coil heating, and strip coil annealing functions. To minimize the furnace opening cross-sectional area, the furnace shell needs to rotate accordingly to adjust for changes in the strip inlet / outlet angle (0°~25°). This allows for real-time feedback of the inlet / outlet strip angle to the furnace, driving the furnace shell to rotate to the corresponding angle. Compared to the prior art's purely mechanical angle feedback, this utility model offers higher reliability and economy.
[0006] The technical solution of this utility model is as follows:
[0007] A self-feedback rudder roller device for the strip winding angle in a coil annealing furnace is disclosed. The rudder roller device includes a follower bearing frame, a rotating seat, a sliding bearing seat, a clamping roller, and a spring clamper. The rotating seat is mounted on the follower bearing frame, the sliding bearing seat is fixed on the rotating seat, and the spring clamper mounted on the sliding bearing seat clamps the clamping roller.
[0008] The steering roller device is fixedly installed on the heat preservation furnace shell through a follower bearing bracket. After the strip is turned by the steering roller, the in-and-out angle of the strip wound on the reel is fed back in real time and drives the heat preservation furnace shell to rotate to the corresponding position, so as to realize the function of the heat preservation furnace shell following the in-and-out angle of the strip.
[0009] There are two follower bearing frames, located on both sides of the rudder roller device, with their lower ends fixed to the heat preservation furnace shell. Each follower bearing frame has a rotating seat installed on its upper end. There are two rotating seats, which can rotate freely and are installed on the follower bearing frame. They can rotate circumferentially with the heat preservation furnace shell together with the follower bearing frame.
[0010] There are four sliding bearing seats, which are installed in the sliding grooves of the rotating seat and can slide up and down on the rotating seat to realize the opening and closing action.
[0011] There are two clamping rollers, one on top and one on the bottom, which are mounted on sliding bearing seats. Each clamping roller is fixed by two sliding bearing seats on the left and right sides. The clamping roller can rotate freely and slide up and down with the sliding bearing seats to achieve the clamping action.
[0012] There are four sets of spring clamps. The spring clamps are installed on the sliding bearing seats and press the two sliding bearing seats together to achieve the clamping action. The two sliding bearing seats and the two sets of spring clamps form a group, and there are two groups in total to achieve the clamping function of the two clamping rollers.
[0013] In operation, the strip is drawn from the guide rollers and passes through the clamping channel formed by the upper and lower clamping rollers. When the reel diameter changes, causing a change in the strip's entry and exit angle, the strip tension drives the clamping rollers to produce lateral displacement, which in turn drives the rotating seat to rotate via the sliding bearing seat. The rotation angle of the rotating seat is transmitted to the insulation furnace shell through the follower bearing bracket, ensuring that the outlet of the insulation furnace shell is always optimally aligned with the strip. The spring clamping device automatically compensates for changes in strip thickness, ensuring the stability of the clamping force.
[0014] The beneficial effects of this utility model are as follows:
[0015] This invention solves the problem of uncertain furnace opening position caused by the continuous change in the inlet and outlet angle of the strip as the roll diameter changes during the winding and unwinding process. This device provides real-time feedback on the inlet and outlet angle of the strip and drives the furnace shell to rotate to the corresponding position. It also achieves bidirectional follow-up function and realizes fully mechanical passive strip angle feedback. It uses the tension of the strip to drive the furnace shell to rotate to the corresponding angle. No manual intervention is required during the online winding process. The furnace shell angle can be adjusted bidirectionally to adapt to the inlet and outlet angle of the strip. Attached Figure Description

[0024] The steering roller device 8 is fixedly installed on the heat preservation furnace shell 9 through the follower bearing frame 1. After the strip 6 is turned by the steering roller 7, the in-and-out angle of the strip wound on the reel 10 is fed back in real time and drives the heat preservation furnace shell 9 to rotate to the corresponding position, so as to realize the follower function of the heat preservation furnace shell 9 according to the in-and-out angle of the strip.
[0025] There are two follower bearing frames 1, located on both sides of the rudder roller device 8, with their lower ends fixed to the heat preservation furnace shell 9.

They can rotate together with the follower bearing frame 1 and the heat preservation furnace shell 9 in a circumferential direction.
[0026] There are four sliding bearing seats 3, which are installed in the sliding groove of the rotating seat 2 and can slide up and down on the rotating seat 2 to realize the opening and closing action.
[0027] There are two clamping rollers 4, one on top and one on the bottom, which are installed on the sliding bearing seats 3. Each clamping roller 4 is fixed by the two sliding bearing seats 3 on the left and right. The clamping roller 4 can rotate freely and slide up and down with the sliding bearing seats 3 to achieve the clamping action.
[0028] There are four sets of spring clamps 5. The spring clamps 5 are installed on the sliding bearing seats 3 to press the two sliding bearing seats 3 together to achieve the clamping action. The two sliding bearing seats 3 and the two sets of spring clamps 5 form a group, and there are two groups in total to achieve the clamping function of the two clamping rollers 4.
[0029] In use, the strip 6 is drawn out from the guide roller 7 and passes through the clamping channel formed by the upper and lower clamping rollers 4. When the diameter of the reel 10 changes, causing a change in the angle of the strip's entry and exit, the tension of the strip 6 drives the clamping rollers 4 to produce lateral displacement, which in turn drives the rotating seat 2 to rotate via the sliding bearing seat 3. The rotation angle of the rotating seat 2 is transmitted to the insulation furnace shell 9 through the follower bearing bracket 1, ensuring that the outlet of the insulation furnace shell 9 is always optimally aligned with the strip 6. The spring clamp 5 can automatically compensate for changes in the thickness of the strip 6, ensuring the stability of the clamping force.
