DETAILED DESCRIPTION

[0021] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0022] As attached Figure 1As shown, the utility model is an annealing tension control device for an etched strip annealing furnace. The annealing furnace 1 includes an etched strip inlet section 2 and an etched strip outlet section 3. A front-of-furnace S-roller group 4 is arranged near the etched strip inlet section 2 inside the annealing furnace 1. The front-of-furnace S-roller group 4 is arranged between the etched strip inlet section 2 and a jumping roller 5. A rear-of-furnace S-roller group 6 is arranged near the etched strip outlet section 3 inside the annealing furnace 1. The above structure addresses the shortcomings of the existing technology and proposes an improved technical solution. When setting up the structure, the annealing furnace 1 is selected. The annealing furnace 1 includes an etched strip inlet section 2 and an etched strip outlet section 3. The etched strip inlet section 2 is used for the etched strip to enter for annealing, and the etched strip outlet section 3 is used for the etched strip to exit for annealing. A furnace front S roller group 4 is set near the etching strip inlet section 2 inside the annealing furnace 1. In this way, when the etched strip passes through the furnace front S roller group 4, it will bypass each furnace front roller of the furnace front S roller group 4 in sequence. The furnace front S roller group 4 is set between the etching strip inlet section 2 and the dancing roller 5. Therefore, the etched strip 14 that bypasses each furnace front roller must also bypass the dancing roller 5 to achieve tension control and prevent the etched strip from loosening. A furnace rear S roller group 6 is set near the etching strip outlet section 3 inside the annealing furnace 1. Therefore, the etched strip 14 must also bypass multiple furnace rear rollers of the furnace rear S roller group 6 in sequence. In this way, the speed and driving force of the etched strip after entering the annealing furnace 1 are controlled by the furnace front S roller group 4, and the speed and driving force of the etched strip when leaving the annealing furnace 1 are controlled by the furnace rear S roller group 6. A reliable tension is formed on the etched strip 14 between the furnace front S roller group 4 and the furnace rear S roller group 6, realizing high tension control, and the tension can be adjusted according to the different models and sizes of the etched strip, thereby effectively meeting the tension control during the production of the etched strip and improving the annealing quality of the etched strip. The annealing tension control device for the etched strip annealing furnace described in the utility model has a simple structure, increases the strip tension during the annealing treatment of the etched strip, realizes low-temperature high-tension annealing, and meets the production needs of the etched strip.

[0023] The aforementioned S-roller assembly 4 includes multiple rollers 7 mounted on a pre-installation frame 8. The S-roller assembly 6 includes multiple post-installation rollers 9 mounted on a post-installation frame 10. With this structure, the pre-installation frame securely mounts the rollers, allowing the etched strip to bypass the rollers, allowing external force to be applied to the strip at the annealing furnace's pre-installation position. The post-installation frame securely mounts the rollers, allowing the strip to bypass the rollers, allowing external force to be applied to the strip at the annealing furnace's post-installation position. The rotational speeds of the pre-installation and post-installation rollers can be controlled independently, and the tension of the etched strip can be controlled through the forces acting in front and behind.

[0024] The multiple front rollers 7 of the front S roller group 4 include a driving front roller and multiple driven front rollers, and the multiple rear rollers 9 of the rear S roller group 6 include a driving rear roller and multiple driven rear rollers. With this structure, the driven front roller and rear roller can be controlled to rotate, driving the etched strip to move within the annealing furnace, ensuring reliable tension.

[0025] The annealing furnace 1 also includes a heating zone 11 and a cooling zone 12. An isolation plate 16 is provided on the side of the heating zone 11 near the dancer roller 5, the side of the heating zone 11 near the cooling zone 12, and the side of the cooling zone 12 near the rear S-roller group 6. In this structure, multiple isolation plates isolate different areas within the annealing furnace to prevent them from interfering with each other.

[0026] The heating zone 11 is located behind the dancing roller 5, and the cooling zone 12 is located behind the heating zone 11. In the above structure, the heating zone is used for heating the strip, and the cooling zone is used for cooling.

[0027] The dancing roller 5 is connected to an adjustment cylinder 13, which is fixed to a bottom base 15 within the annealing furnace 1. In this structure, the adjustment cylinder is fixed to the bottom base, and the dancing roller applies pressure to the strip. When the force of the strip is greater than that of the adjustment cylinder, the strip exerts force on the adjustment cylinder, causing it to retract. When the force of the strip is less than that of the adjustment cylinder, the adjustment cylinder extends, and the dancing roller applies force to the strip, achieving tension control.

[0028] The etched strip 14 is configured to sequentially bypass the multiple pre-heater rollers 7 of the pre-heater S-roller group 4. After bypassing the multiple pre-heater rollers 7 of the pre-heater S-roller group 4, the etched strip 14 is configured to bypass the dancer roller 5. The etched strip 14 bypassing the dancer roller 5 is configured to sequentially pass through the heating zone 11 and the cooling zone 12. After passing through the cooling zone 12, the etched strip 14 is configured to bypass the multiple post-heater rollers 9 of the post-heater S-roller group 6. A heater is provided in the heating zone 11, and a cooler is provided in the cooling zone 12. In this configuration, the heater controls the start and stop of heating and temperature control. The cooler controls the start and stop of cooling and temperature control.

[0029] The annealing tension control device for an etched strip annealing furnace described in the present invention comprises an annealing furnace 1, which includes an etched strip inlet section 2 and an etched strip outlet section 3. The etched strip inlet section 2 is used for the etched strip to enter for annealing, and the etched strip outlet section 3 is used for the etched strip to exit for annealing. A furnace front S roller group 4 is provided near the etched strip inlet section 2 within the annealing furnace 1. Thus, when the etched strip passes through the furnace front S roller group 4, it sequentially bypasses each furnace front roller of the furnace front S roller group 4. The furnace front S roller group 4 is provided between the etched strip inlet section 2 and the jumping roller 5. Therefore, the etched strip 14 that bypasses each furnace front roller also bypasses the jumping roller 5, achieving tension control and preventing the etched strip from loosening. A furnace rear S roller group 6 is provided near the etched strip outlet section 3 within the annealing furnace 1. Therefore, the etched strip 14 also sequentially bypasses multiple furnace rear rollers of the furnace rear S roller group 6. In this way, the speed and driving force of the etched strip after entering the annealing furnace 1 are controlled by the S roller group 4 in front of the furnace, and the speed and driving force of the etched strip when leaving the annealing furnace 1 are controlled by the S roller group 6 in the back of the furnace. Reliable tension is formed on the etched strip 14 between the S roller group 4 in front of the furnace and the S roller group 6 in the back of the furnace, and large tension control is achieved. In addition, the tension can be adjusted according to the model and size of the etched strip to meet the tension control during the production of the etched strip and improve the annealing quality of the etched strip.

[0030] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
