DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] See also Figures 1 to 3 The embodiment of the utility model provides a profile straightening device, which belongs to the field of profile processing and is used to straighten profiles. The profile straightening device can be used to adapt to profiles of different specifications, thereby improving the application range of the profile straightening device.

[0026] In some preferred embodiments, the profile straightening device includes a frame 100, a roller assembly 200 and a driving assembly 300, wherein the roller assembly 200 includes a plurality of first straightening rollers 210 and a plurality of second straightening rollers 220 rotatably mounted on the frame 100, the plurality of first straightening rollers 210 and the plurality of second straightening rollers 220 are arranged alternately, and a straightening gap 230 is provided between the first straightening rollers 210 and the second straightening rollers 220. The driving assembly 300 includes a rotating driving member 310 and a distance-adjusting driving member 320, the rotating driving member 310 drives the first straightening roller 210 and the second straightening roller 220 to rotate relative to each other, and the distance-adjusting driving member 320 drives the second straightening roller 220 to translate relative to the first straightening roller 210 to adjust the size of the straightening gap 230.

[0027] In the above embodiment, the profile to be straightened is first introduced into the straightening gap 230, and the rotating driving member 310 drives the first straightening roller 210 and the second straightening roller 220 to rotate relative to each other, thereby driving the profile to move in the straightening gap 230. Since the first straightening rollers 210 and the second straightening rollers 220 are arranged alternately, the profile is repeatedly bent alternately by the first straightening rollers 210 and the second straightening rollers 220 during the process of passing through the straightening gap 230, thereby achieving the purpose of straightening the profile. The distance between the first straightening roller 210 and the second straightening roller 220 is adjusted by the distance adjusting driving member 320, and the width of the straightening gap 230 is changed, so that the profile straightening device can adapt to profiles of different specifications, thereby improving the application range of the profile straightening device.

[0028] In some preferred embodiments, the rotation driving member 310 includes a plurality of second driving parts 312 corresponding one-to-one to the plurality of second straightening rollers 220 , and the second driving parts 312 drive the second straightening rollers 220 to rotate.

[0029] In the above embodiment, a plurality of second driving parts 312 are used to drive each second straightening roller 220 respectively, so as to adjust the position of each second straightening roller 220 individually, thereby avoiding the installation of the second driving parts 312 affecting the individual adjustment of each second straightening roller 220 .

[0030] On the basis of the above embodiments, in some preferred embodiments, the second driving unit 312 includes a second motor 3121 and a flexible coupling 3122, and the two ends of the flexible coupling 3122 are respectively connected to the rotating shaft of the second motor 3121 and the second straightening roller 220. Since the second motor 3121 and the second straightening roller 220 are connected via the flexible coupling 3122, when the second straightening roller 220 moves relative to the second motor 3121, the flexible coupling 3122 can still transmit smoothly.

[0031] In some preferred embodiments, a plurality of first straightening rollers 210 are in transmission connection with each other, and the rotation driving member 310 includes a first driving portion 311 , and the first driving portion 311 drives one of the first straightening rollers 210 to rotate.

[0032] In the above embodiment, since each first straightening roller 210 does not need to move relative to the frame 100, the first straightening rollers 210 can be connected to each other by transmission, and then the first driving part 311 is used to drive one of the first straightening rollers 210 to rotate, so that all the first straightening rollers 210 can be driven to rotate synchronously.

[0033] As long as the relative movement of the first straightening roller 210 and the second straightening roller 220 can be adjusted, any implementation is feasible. In some preferred embodiments, the distance adjustment drive 320 includes a lifting seat 321 and a lifting drive unit 322. The lifting seat 321 is slidably arranged on the frame 100 along the vertical direction, and the lifting seat 321 supports the second straightening roller 220. The lifting drive unit 322 drives the lifting seat 321 to slide.

[0034] On the basis of the above embodiments, in some preferred embodiments, the lifting seat 321 has a rack (not shown in the figure), the lifting drive unit 322 includes a lifting motor 3221 and a lifting shaft 3222, the lifting shaft 3222 is provided with a lifting gear (not shown in the figure), the lifting gear (not shown in the figure) is meshed with the rack (not shown in the figure), and the lifting motor 3221 drives the lifting shaft 3222 to rotate to drive the lifting seat 321 to move.

[0035] In the above embodiment, the lifting motor 3221 drives the rotating shaft to rotate, thereby driving the lifting gear (not shown in the figure) to rotate. Since the lifting gear (not shown in the figure) and the rack (not shown in the figure) are engaged with each other, the lifting motor 3221 can drive the lifting seat 321 to move.

[0036] It should be emphasized that the implementation method of the lifting drive unit 322 is not the only one, and structures such as a screw slider structure, a hydraulic cylinder (cylinder) and the like can also play the role of driving the second straightening roller 220 to move.

[0037] In some preferred embodiments, a baffle 211 is provided on the outer periphery of the first straightening roller 210 , and the baffle 211 can block the profile to prevent the profile from moving along the circumference of the first straightening roller 210 and leaving the straightening gap 230 .

[0038] In some preferred embodiments, the profile straightening device further comprises an introduction component 400, which is mounted at one end of the straightening gap 230 and is used to introduce the profile into the straightening gap 230. Under the guidance of the introduction component 400, the profile can be more easily aligned with the straightening gap 230.

[0039] On the basis of the above embodiments, in some preferred embodiments, the introduction assembly 400 includes two guide plates 410 arranged opposite to each other, and a guide channel 420 communicating with the straightening gap 230 is provided between the two guide plates 410, and the width of the guide channel 420 is larger at one end away from the straightening gap 230. The profile is introduced into the guide channel 420 from the end with the larger width, and under the guidance of the guide plate 410, the profile is aligned with the straightening gap 230, so that the profile can be smoothly introduced into the straightening gap 230.

[0040] In some preferred embodiments, the introduction assembly 400 further includes a guide drive 430 and two guide rollers 440. The two guide rollers 440 are arranged opposite to each other and are rotatably arranged on both sides of the guide channel 420. The guide drive 430 drives the two guide rollers 440 to rotate relative to each other. The guide drive 430 drives the guide rollers 440 to rotate, so that the rotating guide rollers 440 can be used to pull the profile to move.

[0041] The profile is introduced into the guide channel 420 from the end with a larger width. Under the guidance of the guide plate 410, the profile is aligned with the straightening gap 230. The guide drive 430 drives the guide roller 440 to rotate, so that the profile can be pulled by the rotating guide roller 440 to move, so that the profile gradually enters the straightening gap 230. The rotating drive 310 drives the first straightening roller 210 and the second straightening roller 220 to rotate relative to each other, thereby driving the profile to move in the straightening gap 230. Since the first straightening rollers 210 and the second straightening rollers 220 are staggered, the profile is repeatedly bent alternately by the first straightening rollers 210 and the second straightening rollers 220 during the process of passing through the straightening gap 230, thereby achieving the purpose of straightening the profile. The distance between the first straightening roller 210 and the second straightening roller 220 is adjusted by the distance adjustment drive 320, and the width of the straightening gap 230 is changed, so that the profile straightening device can adapt to profiles of different specifications, thereby improving the application range of the profile straightening device.

[0042] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
