[0034] Example 1

[0035] Reference Figures 1 to 3 This is the first embodiment of the present utility model. This embodiment provides a straightening and tensioning mechanism for metal strip, which can facilitate the rapid feeding of coiled metal strip by the unwinding roller. It includes: a base 100, which provides an installation foundation for the entire mechanism.

[0036] An unwinding assembly 200 and a rewinding assembly 500 are provided on a base 100. The unwinding assembly 200 includes an F-shaped frame 201, which is fixedly connected to the base 100. An unwinding roller 202 is fixedly connected to the side wall of the F-shaped frame 201. A spring telescopic rod 203 is provided on the top of the F-shaped frame 201. A pressure plate 204 is fixedly connected to the bottom of the spring telescopic rod 203. An unwinding unit 205 is also provided on the unwinding assembly 200.

[0037] The straightening component 300 and the tension straightening component 400 are provided between the unwinding component 200 and the winding component 500 for straightening and tensioning the metal strip.

[0038] In use, the rolled metal strip is quickly placed onto the unwinding roller 202 through the unwinding unit 205. At the same time, after the unwinding roller 202 is put onto the unwinding roller 202, the spring telescopic rod 203 will be squeezed and deformed and move upward. The pressure plate 204 plays a pre-tightening role on the rolled metal strip on the unwinding roller 202. When unwinding starts, the operator manually pulls the head of the metal strip. First, it passes through the correction component 300 for correction, and then through the tension straightening component 400 to guide the metal strip to the take-up component 500 for correction and tension straightening.

[0039] Example 2

[0040] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the unwinding unit 205 includes an unwinding table 2051 fixedly connected to the base 100. The unwinding table 2051 has a groove 2052. A hydraulic cylinder 2053 is fixedly connected to the side wall of the unwinding table 2051. A push plate 2054 is fixedly connected to the piston end of the hydraulic cylinder 2053. The push plate 2054 is located in the groove 2052. The unwinding table 2051 has an inclined angle for the rolled metal strip to roll onto the arc-shaped inner wall of the groove 2052. The arc-shaped inner wall of the groove 2052 is consistent with the shape and size of the push plate 2054, and the push plate 2054 fits against the arc-shaped inner wall of the groove 2052.

[0041] The correction component 300 includes a U-shaped frame 301 fixedly connected to the base 100, a roller 302 rotatably connected to the inner wall of the U-shaped frame 301, a bidirectional lead screw 303 rotatably connected to the center of the inner wall of the U-shaped frame 301, a first motor 304 fixedly connected to the side wall of the U-shaped frame 301, a bidirectional lead screw 303 fixedly connected to the output end of the first motor 304, a threaded block 305 threadedly connected to the outside of the bidirectional lead screw 303, the top of the threaded block 305 fitting against the U-shaped frame 301, and an anti-deviation wheel 306 fixedly connected to the bottom of the threaded block 305. The threaded block 305 and the anti-deviation wheel 306 are provided in two sets, located on the left-hand and right-hand sides of the bidirectional lead screw 303.

[0042] The tension straightening assembly 400 includes a vertical plate 401 fixedly connected to the base 100, a pressure roller 402 rotatably connected to the inner wall of the vertical plate 401, a second motor 403 fixedly connected to the outer wall of the vertical plate 401, a drive gear 404 fixedly connected to the output end of the second motor 403, a driven gear 405 rotatably connected to the outer wall of the vertical plate 401, the drive gear 404 meshing with the driven gear 405, and both the drive gear 404 and the driven gear 405 fixedly connected to the pressure roller 402.

[0043] The winding assembly 500 includes a vertical plate 501 fixedly connected to the base 100. A winding roller 502 and a tensioning column 503 are fixedly connected to the inner wall of the vertical plate 501. A third motor 504 is fixedly connected to the outer wall of the vertical plate 501. The output end of the third motor 504 is fixedly connected to the winding roller 502.

[0044] In use, the unwinding table 2051 is tilted, allowing the coiled metal strip to roll onto the arc-shaped inner wall of the groove 2052. Then, the hydraulic cylinder 2053 is activated to push the push plate 2054, pushing the coiled metal strip onto the unwinding roller 202. The hydraulic cylinder 2053 retracts, and the metal strip, under traction, enters between the two sets of rollers 302. The first motor 304 drives the bidirectional lead screw 303 to rotate, which in turn drives the two sets of threaded blocks 305 to move synchronously. The tops of the threaded blocks 305 are in contact with the bottom of the U-shaped frame 301, maintaining its linear motion. The rollers move closer to or further away from each other, thereby moving the anti-deviation rollers 306 to adapt to metal strips of different sizes and prevent the metal strips from deviating. The second motor 403 drives the drive gear 404 to rotate, and the drive gear 404 meshes with the driven gear 405, which in turn causes the two sets of pressure rollers 402 to rotate, rolling the surface of the metal strip and improving the shape of the metal strip. The processed metal strip is then driven by the third motor 504 to rotate the take-up roller 502. The metal strip passes the bottom of the tensioning column 503 and then winds back to the upper take-up roller 502 to wind up the metal strip.

[0045] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
