DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0028] Example 1

[0029] Reference Figure 1 、 Figure 2 and Figure 3As shown, the utility model is a tension calibration device for a copper foil surface treatment machine, comprising:

[0030] Overhead crane 1, including a hook;

[0031] The tension stabilizing structure 2 includes a first load-bearing rod 21 and a second load-bearing rod 22 arranged in parallel. Two mutually symmetrical elastic members 23 are vertically connected between the first load-bearing rod 21 and the second load-bearing rod 22. The first load-bearing rod 21 is horizontally suspended on the hook;

[0032] The hook scale 3 is suspended on the second load-bearing rod 22;

[0033] The hanging rope 4 is connected to the hook of the hook scale 3.

[0034] Operation process: Connect the hook of the overhead crane 1, the tension stabilizing structure 2, the hook scale 3 and the rope 4 in sequence, and put the rope 4 on the middle position of the tension roller to be calibrated (the rope 4 needs to be vertical); before the tension roller is subjected to force, operate on the control interface of the copper foil surface treatment machine to "clear the tension of the corresponding tension roller", and the [zeroing in progress] on the interface will change from green to yellow, and the value will be 0; then start to control the overhead crane 1 to rise, so that the weighing value of the hook scale 3 is within the predetermined range (it can be between 150-200), and set the "tension value" to correspond to the weighing value; click "execute span" on the control interface, and [zeroing in progress] will change from yellow to green and then to yellow; then confirm whether the "tension feedback" and "span tension value" correspond, if they do, they are correct; lower the overhead crane 1 and raise it again, set the "tension value", and confirm again whether the "tension feedback" and "span tension value" correspond, if they do, press the "request command completion" button, which will change from yellow to green, and the tension roller calibration is now completed.

[0035] It should be noted that: (1) during the tension calibration process of the tension roller, no other objects can be placed on the tension roller, and the tension roller must not be affected by any external forces. (2) when operating, you must first click "Tension Calibration Enable" before you can control the interface. (3) after the tension calibration is completed, you must click "Request Command Complete" to complete it. (4) during the tension calibration, the overhead crane 1 will no longer move left or right, ensuring that it is in the middle of the tension roller. (5) when operating the overhead crane 1, you must click the button gently to avoid operating the crane too fast and damaging the tension roller due to operating errors.

[0036] Specifically, the tension calibration device is equipped with a tension stabilizing structure. The elastic member (spring) 23 of the tension stabilizing structure has linear elasticity. It can act as a buffer when the overhead crane 1 starts and stops, preventing the external force from suddenly increasing or decreasing during the tension calibration process. It ensures the stability and uniformity of the force changes throughout the pulling process, thereby ensuring the accuracy of the calibration results. The entire device has a simple structure, is easy to install and operate, and has high practicality.

[0037] Furthermore, a first lifting ring 24 is movably provided at the middle position of the side surface of the first load-bearing rod 21 , and the first load-bearing rod 21 is suspended on the hook through the first lifting ring 24 .

[0038] Furthermore, the first hanging ring 24 includes an annular body with a notch, and mutually parallel connecting parts are provided on the two ends of the annular body. Coaxial through holes are opened on the two connecting parts, and bolts are passed through the through holes, and nuts are screwed on the bolts.

[0039] Furthermore, a second lifting ring 25 is movably provided at the middle position of the side of the second load-bearing rod 22, and the hook scale 3 is suspended on the second lifting ring 25. It can be imagined that the first lifting ring 24 and the second lifting ring 25, which are respectively located at the middle position of the first load-bearing rod 21 and the second load-bearing rod 22, can ensure that the force line is at the center line position of the device when the entire device is connected, thereby ensuring the balance and stability of the force during the calibration process, which is conducive to the accuracy of the calibration result.

[0040] Furthermore, two connecting rings 26 are symmetrically provided on the side surfaces of the first load-bearing rod 21 and the second load-bearing rod 22, respectively, near their ends. The ends of the elastic member 23 are respectively connected to a connecting ring 26 of the first load-bearing rod 21 and the second load-bearing rod 22. Specifically, the connecting ring 26 is provided on the side of the first load-bearing rod 21 away from the first hanging ring 24, and the connecting ring 26 is provided on the side of the second load-bearing rod 22 away from the second hanging ring 25.

[0041] Furthermore, the elastic member 23 is a spring with hooks at both ends, and the two springs are connected to two opposite connecting rings 26 of the first bearing rod 21 and the second bearing rod 22 through the hooks at both ends.

[0042] Furthermore, the connecting ring 26 includes an annular body 261, with a stud 262 vertically connected to the side of the annular body 261. Two threaded holes are vertically opened on the side of the first bearing rod 21 and the second bearing rod 22, respectively, near their ends. The connecting ring 26 is screwed into one of the threaded holes through the stud 262. Specifically, the first bearing rod 21 and the second bearing rod 22 are respectively provided with a connecting ring 26 that can be threadedly connected, and the two ends of the spring are hooked on the connecting ring 26 to form a tension stabilizing structure. In this way, the tension stabilizing structure becomes a structure composed of multiple detachable parts, which is convenient for storage. When a part is damaged, it can be replaced separately, which can reduce the cost of use.

[0043] Furthermore, the first load-bearing rod 21 and the second load-bearing rod 22 can be made of steel bars or round steel bars.

[0044] Furthermore, the hanging rope 4 is a hemp rope. Specifically, the hanging rope 4 is a rope that is not elastic or has relatively small elasticity, and the hanging rope 4 can be a hemp rope.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
