[0014] The beneficial effects are as follows:

[0015] This invention has multiple correction functions and can adapt to different offset situations. It monitors the metal belt offset in real time through a deviation measuring device and uses the elastic force of the outer spring of the slide rod to achieve normal dynamic centering correction. When the offset exceeds the normal range, the upper and lower pressure plates are activated to constrain the metal belt vertically and vertically. Combined with the mechanical pressure of the correction wheel, it performs forced correction, which can effectively solve the problems of left and right offset and deformation of the metal belt and ensure the accuracy of the conveying path.

[0016] The winding and conveying mechanisms work closely together to improve operational stability. The upper and lower clamping teeth of the U-shaped clamps work together to firmly hold the ends of the metal strip. Combined with the traction of the connecting belt and the inner shaft, the metal strip is easily guided into the winding wheel. The slot of the winding wheel has a front-wide and rear-narrow structure, which is conducive to bending and winding the edges and corners of the metal strip. At the same time, the winding motor drives the winding wheel through a worm gear and gear transmission, ensuring smooth transmission and stable winding process.

[0017] The structure is flexible and easy to operate and maintain. The winding wheel is supported by the lower support wheel and the upper support wheel. The electric cylinder A can control the lifting and lowering of the upper support wheel, which facilitates the replacement of the winding wheel. The brush and resistance plate of the deviation measuring device work together to accurately feed back the deviation and provide data support for deviation correction. The components driven by each electric cylinder, such as the deviation correction wheel and the upper pressure plate, can be replaced and adapted according to the size of the metal strip to meet the conveying needs of metal strips of different specifications.

[0036] The U-shaped clamp 4 has a lower clamping tooth block 401 fixedly installed inside the lower part; an upper clamping tooth block 402 is installed inside the upper part of the U-shaped clamp 4, and four sets of T-shaped rods 403 are fixedly installed on the top of the upper clamping tooth block 402.

[0039] Four sets of telescopic rods 702 are fixedly installed between the bottom of the lower pressure plate 701 and the base 1.

Brushes 905 are fixedly installed on both sides of the movable block 903. The two brushes 905 are connected and respectively contact the two resistance plates 901.

[0041] Initial guidance and clamping fixation

[0042] The metal strip exported from the preparation equipment passes over the guide roller 8, and the side-adhesive correction wheel 502 and the adhesion wheel 904 complete the initial guidance; the U-shaped clamp 4 is fastened to the side of the metal strip, and after measurement and positioning, the top screw 404 is rotated to advance the upper clamping tooth block 402, which cooperates with the lower clamping tooth block 401 to clamp and fix the metal strip. The U-shaped clamp 4 extends the stretching distance to increase the measurable range.

[0043] Metal belt traction

[0044] Turning the handwheel 305 drives the inner shaft 304 to rotate, winding up the connecting belt 306, and pulling the U-shaped clamp 4 to move the metal belt backward; when the U-shaped clamp 4 is pulled into the through slot 303 of the winding wheel 3, check the alignment pin hole A307 and pin hole B405, and insert the magnetic pin to fix it.

[0045] Automatic winding operation

[0046] Start the winding motor 104 to drive the transmission worm gear 105 to rotate, which in turn drives the driven worm wheel 106, the transmission gear 107, and the driven gear 302 to rotate in sequence, causing the winding wheel 3 to rotate as a whole. This bends the edges and corners of the metal strip and continuously winds it around the outside of the winding wheel 3, completing the conventional winding and conveying process.

[0047] Example 2: Metal Strip Offset Monitoring and Routine Correction Operation

[0048] Offset monitoring mechanism

[0049] During the metal strip conveying process, the movable block 903 and the contact wheel 904 always contact its side; if a normal deviation occurs, the spring outside the slide bar 902 will push the movable block 903 and the contact wheel 904 to try to automatically center the metal strip; if the metal strip is deformed, the contact wheel 904 will move with the protruding part, causing the movable block 903 and the brush 905 to slide on the resistor 901;

[0050] Offset calculation

[0051] Two adjacent sets of resistors 901 are connected to the monitoring device through a line. The brush 905 and the resistors 901 form a sliding rheostat. The monitoring device calculates the offset length of the metal strip by the resistance change of the resistors 901 and provides real-time feedback on the offset status.

[0052] Standard correction operation

[0053] When the offset is within the allowable range, the spring force of the slide bar 902 makes the contact wheel 904 continuously contact the side of the metal strip, and the elastic force is used to achieve dynamic centering and correction without the need for additional power intervention.

[0054] Example 3: Forced alignment of metal strip and replacement of winding component

[0055] Forced correction trigger conditions

[0056] When the monitoring equipment shows that the offset length exceeds the normal correction range and the offset position moves between the two sets of correction wheels 502, the forced correction procedure is started: first, the metal belt conveyor is stopped, the electric cylinder D7 is started to raise the lower pressure plate 701 to support the metal belt below, and then the electric cylinder C601 is started to lower the upper pressure plate 602 to contact the upper part of the metal belt. The upper and lower constraints prevent the edge from lifting during correction.

[0057] Step-by-step forced correction

[0058] Select a straightening wheel 502 with a thickness slightly smaller than that of the metal strip, start the electric cylinder B503 to push the straightening wheel 502 forward, and use mechanical pressure to forcefully correct the offset part of the metal strip; after each correction, reset the electric cylinder B503 and feed the metal strip according to its stroke, repeat the operation until the correction is complete, and ensure that the edge of the metal strip is flat.

[0059] Replacement process

[0060] After the metal strip is wound up, the electric cylinder A201 is retracted, which drives the upper support frame 202 and the upper support wheel 203 to rise, unlocks the T-shaped side edge 301 of the winding wheel 3, and removes the fully wound winding wheel 3; after placing the new winding wheel 3, the electric cylinder A201 is extended to reset the upper support wheel 203, and the winding wheel 3 is re-fixed to prepare for the next round of operation.

[0061] The specific usage and function of this embodiment: In this invention, when used, according to... Figure 1 In this manner, the metal strip exported by the preparation equipment passes over the guide roller 8, and the metal strip side is bonded to the correction wheel 502 and the bonding wheel 904;

[0062] The metal strip is fixed by U-shaped clip 4 to extend the stretching distance and increase the measurable distance of the metal strip;

[0063] Attach the U-shaped clamp 4 to the side of the metal strip, measure and position it, rotate the set screw 404 to push the upper clamping tooth block 402, use the upper clamping tooth block 402 and the lower clamping tooth block 401 to clamp and fix the metal strip, rotate the handwheel 305 to drive the inner shaft 304 to rotate, and then roll up the connecting belt 306, thereby pulling the U-shaped clamp 4 to move the metal strip backward.

[0064] When the U-shaped clip 4 is pulled into the through slot 303, align the pin hole A307 and the pin hole B405, and then insert a magnetic pin in the pin hole A307 and the pin hole B405 for fixation.

[0065] Then, the winding motor 104 is started to drive the transmission worm gear 105 to rotate. The transmission worm gear 105 drives the driven worm wheel 106 to rotate. The driven worm wheel 106 coaxially drives the transmission gear 107 to rotate. The transmission gear 107 drives the driven gear 302 to rotate, so that the winding wheel 3 rotates as a whole to wind up the metal strip, bend the corners of the metal strip, and wind the subsequent metal strip onto the outside of the winding wheel 3.

[0066] This allows for the continuous winding and conveying of the metal strip;

[0067] During the movement of the conveyor belt, the movable block 903 is in contact with the side of the metal belt. If the conveyor belt deviates normally, the movable block 903 and the contact wheel 904 can be pushed by the spring outside the slide rod 902 to try to center the metal belt. However, if the metal belt is deformed, the contact wheel 904 will move along the protruding part of the metal belt, driving the movable block 903 and the brush 905 to move. The brush 905 moves outside the resistor 901. The two adjacent sets of resistors 901 are connected to the monitoring equipment. The brush 905 and the resistor 901 form a sliding rheostat. By monitoring the resistance change of the resistor 901, the length of the metal belt deviation can be calculated during the movement of the metal belt, and then the control program can be used for subsequent correction.

[0068] When the offset position moves close to the two sets of straightening rollers 502, if it passes directly through the straightening rollers 502, the metal strip may be affected by torque and tilt instead of being restored. Therefore, the electric cylinder D7 is activated to raise the lower pressure plate 701, which supports the lower part of the metal strip. The electric cylinder C601 is activated to lower the upper pressure plate 602, which contacts the upper part of the metal strip. At this time, the metal strip is stopped from being fed. The offset part of the metal strip is restricted both above and below to prevent tilting. The electric cylinder B503 is activated to push the straightening rollers 502 forward. The pressure generated by the straightening rollers 502 is used to forcibly correct the metal strip. After each correction, the strip is reset and fed back. The forced correction is repeated to achieve the correction. The amount of metal strip fed each time is consistent with the stroke of the electric cylinder B503.

[0069] The thickness of the alignment roller 502 should be selected as needed, ensuring that it can contact the metal belt and that its thickness is slightly less than that of the metal belt to avoid jamming.

[0070] After winding is completed, the retraction electric cylinder A201 raises the upper support frame 202 and the upper support wheel 203, which unlocks the T-shaped side edge 301. At this time, the winding wheel 3 can be removed. Conversely, after placing a new winding wheel 3, the extension electric cylinder A201 can fix the upper support wheel 203.
