[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A double-roll plate straightening machine with adjustable roller pitch includes a frame 1. A lower straightening roller 2 is provided at the bottom of the inner cavity of the frame 1. The two sides of the surface of the lower straightening roller 2 are rotatably connected to the inner wall of the frame 1 through bearings. An upper straightening roller 3 is provided at the top of the lower straightening roller 2. Sliding blocks 4 are rotatably connected to the two sides of the surface of the upper straightening roller 3 through bearings. Adjustment components 5 that cooperate with the sliding blocks 4 are provided at the top of both sides of the frame 1. Auxiliary support components 6 are provided on the front and rear sides of the frame 1.

[0027] The adjustment assembly 5 includes a fixed block 501 and a fixed frame 502. The fixed block 501 and the fixed frame 502 are fixedly connected to the frame 1 on the side close to the frame 1, respectively. A stepper motor 503 is fixedly connected to the top of the fixed block 501. A lead screw 504 is fixedly connected to the output end of the stepper motor 503. The bottom of the lead screw 504 passes through the fixed block 501 and the fixed frame 502 in sequence. A transmission block 505 is threadedly connected to the surface of the lead screw 504. The transmission block 505 is fixedly connected to the sliding block 4 on the side close to the sliding block 4.

[0028] In this embodiment, by setting up a frame 1, a lower straightening roller 2, an upper straightening roller 3, a sliding block 4, an adjustment component 5, and an auxiliary support component 6, the heights of the sliding block 4 and the upper straightening roller 3 can be adjusted by setting up the adjustment component 5. By adjusting the height of the upper straightening roller 3, the distance between the upper straightening roller 3 and the lower straightening roller 2 can be adjusted, allowing the upper straightening roller 3 and the lower straightening roller 2 to straighten plates of different thicknesses, improving the flexibility of use. Moreover, the adjustment method of the adjustment component 5 is relatively convenient, bringing convenience to the user. By setting up the auxiliary support component 6, when straightening long plates, the plates can be supported, thus bringing convenience to the straightening work.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the auxiliary support assembly 6 includes two support tubes 601. The side of the support tube 601 closest to the frame 1 is fixedly connected to the frame 1. The front and rear sides of the top of the support tube 601 are provided with first support rollers 602. The two sides of the surface of the first support roller 602 are fixedly connected to the top of the two support tubes 601 through bearing seats. The top of the first support roller 602 is on the same plane as the top of the lower straightening roller 2.

[0030] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, an extension rod 603 is slidably connected to the inner cavity of the support tube 601. A second support roller 604 is provided on the side of the top of the extension rod 603 away from the frame 1. Both sides of the surface of the second support roller 604 are fixedly connected to the top of the two extension rods 603 through bearing seats. The top of the second support roller 604 is on the same plane as the top of the first support roller 602.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, an electric telescopic rod 605 is fixedly connected to the outside of the support tube 601, and a connecting block 606 is fixedly connected to the output end of the electric telescopic rod 605. The side of the connecting block 606 near the extension rod 603 is fixed to the extension rod 603.

[0032] In this embodiment, by setting up a support tube 601, a first support roller 602, an extension rod 603, a second support roller 604, an electric telescopic rod 605, and a connecting block 606, the first support roller 602 and the second support roller 604 can provide auxiliary support for the straightened sheet material during use. When straightening a long sheet material, the electric telescopic rod 605 can be activated, causing its output end to move the connecting block 606. The connecting block 606 then moves the extension rod 603, causing it to extend outward from the inner cavity of the support tube 601. The extension rod 603 then moves the second support roller 604, allowing it to be adjusted to a suitable position. This provides auxiliary support for sheets of different lengths, making the straightening process more convenient.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a limiting rod 7 that works with the transmission block 505 is fixedly connected to the bottom side of the fixed block 501 away from the frame 1. The bottom of the limiting rod 7 passes through the transmission block 505 and is fixedly connected to the top of the fixed frame 502. The inner wall of the transmission block 505 is slidably connected to the surface of the limiting rod 7.

[0034] Specifically, such as Figure 1 , Figure 3 As shown, the top and bottom of the surface of the lead screw 504 are rotatably connected to the inner walls of the fixing block 501 and the fixing bracket 502 via bearings.

[0035] In this embodiment: by setting the limiting rod 7, the transmission block 505 can be assisted in limiting the movement of the transmission block 505 to prevent it from shaking. The top and bottom of the surface of the lead screw 504 are respectively connected to the inner walls of the fixed block 501 and the fixed frame 502 through bearings to facilitate the rotation of the lead screw 504.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, sliding grooves 8 are provided on both sides of the frame 1 to cooperate with the sliding block 4. The surface of the sliding block 4 is slidably connected to the inner wall of the sliding groove 8. A support base 9 is fixedly connected to the bottom of the frame 1. Universal self-locking wheels 10 are fixedly connected to the four corners of the bottom of the support base 9.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a drive motor 11 that works with the lower straightening roller 2 is fixedly connected to the right side of the frame 1, and the output end of the drive motor 11 is fixedly connected to the right end of the lower straightening roller 2.

[0038] In this embodiment: by setting the sliding groove 8, the sliding block 4 can be moved up and down easily, and the sliding block 4 can be limited. By setting the support base 9, the frame 1 can be supported. By setting the universal self-locking wheel 10, the support base 9 can be moved easily, and the position can be locked after movement, thereby improving the flexibility of use. By setting the drive motor 11, the lower straightening roller 2 can be driven to rotate for straightening work.

[0039] Working Principle: In use, the distance between the upper straightening roller 3 and the lower straightening roller 2 is adjusted according to the thickness of the sheet material. Stepper motor 503 is activated, causing its output to drive lead screw 504 to rotate. The rotation of lead screw 504 causes transmission block 505 to slide on the surface of limit rod 7 via a thread. Transmission block 505 drives sliding block 4 to slide within the sliding groove 8. Sliding block 4 moves the upper straightening roller 3, adjusting it to a suitable height. This completes the adjustment of the distance between the upper and lower straightening rollers 3 and 2, which is convenient and precise due to the stepper motor 503. This allows the upper and lower straightening rollers 3 and 2 to easily straighten sheets of different thicknesses. Then, drive motor 11 is activated to rotate the lower straightening roller 2, and the sheet material is placed into the upper straightening roller. Between the upper straightening roller 3 and the lower straightening roller 2, the upper straightening roller 3 will rotate in the opposite direction under the action of friction. By rotating the lower straightening roller 2 and the upper straightening roller 3 in opposite directions at the same time, the plate can be conveyed and straightened. Then, the first support roller 602 and the second support roller 604 can provide auxiliary support for the straightened plate. When straightening a long plate, the electric telescopic rod 605 can be activated, so that the output end of the electric telescopic rod 605 drives the connecting block 606 to move. The connecting block 606 drives the extension rod 603 to move, so that the extension rod 603 extends outward in the inner cavity of the support tube 601. The extension rod 603 drives the second support roller 604 to move, so that the second support roller 604 can be adjusted to a suitable position, thereby providing auxiliary support for plates of different lengths and bringing convenience to the straightening work.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
