[0033] It should be noted that the profile is placed on the workbench 1, and then the electric push rod is started, the output shaft of the electric push rod moves and drives the clamping plate to move, and then the relative movement of the two clamping plates can position the profile.

[0034] See also Figure 2-3In order to clean the surface of the profile, the cleaning mechanism 5 in this embodiment includes two support blocks 51, a driving member 52, two sliders 53 and a cleaning plate 54. The two support blocks 51 are fixed to the left and right ends of the front of the workbench 1 and are used to support the driving member 52. The driving member 52 is arranged in the inner cavity of the two support blocks 51 and is used to drive the cleaning plate 54. The two sliders 53 are arranged on the upper side of the driving member 52 and are used to limit the movement of the driving member 52.

[0035] In this embodiment, the driving member 52 includes a first threaded rod 521, a driving motor 522, a sliding block 523, a fixed block 524, a second threaded rod 525 and a movable plate 526. The two ends of the first threaded rod 521 are rotatably connected to the opposite sides of the two support blocks 51 through bearings.

The driving motor 522 is started. 2, thereby driving the first threaded rod 521 to rotate. The rotation of the first threaded rod 521 causes the sliding block 523 threadedly connected to its surface to move. The movement of the sliding block 523 drives the fixed block 524 to move. The second threaded rod 525 is threadedly connected to the fixed block 524. The upper end of the second threaded rod 525 penetrates the fixed block 524 and extends to the upper side of the fixed block 524. The back side is rotatably connected to the moving plate 526, so that the second threaded rod 525 rotates and moves downward. The movement of the second threaded rod 525 drives the moving plate 526 and the cleaning plate 54 to move downward until the lower surface of the cleaning plate 54 contacts the upper surface of the profile, and the rotation of the second threaded rod 525 stops.

[0036] It should be noted that the two sliders 53 are fixed at the left and right ends of the upper surface of the fixed block 524, the cross-sectional shape of the slider 53 is L-shaped, a slide groove is provided at the top of the front side of the workbench 1, the slider 53 makes horizontal linear motion in the inner cavity of the slide groove, the width of the movable plate 526 is equal to the width of the workbench 1, the lower surface of the movable plate 526 is fixed to the upper surface of the cleaning plate 54, the width of the cleaning plate 54 is equal to the width of the movable plate 526, and a handle is fixed to the lower surface of the second threaded rod 525.

[0037] It can be understood that the movement of the fixed block 524 drives the second threaded rod 525 to move, and then the second threaded rod 525 drives the moving plate 526 and the cleaning plate 54 to move. The movement of the cleaning plate 54 can clean the surface of the profile.

[0038] It should be noted that through rods are fixed to both left and right ends of the bottom of the movable plate 526 , and the lower surface of the through rods passes through the fixed block 524 and extends to the lower side of the fixed block 524 and is slidably connected to the fixed block 524 .

[0039] See also Figure 4 In order to facilitate the staff to straighten the position to be straightened on the same surface of the profile, the adjustment mechanism 8 in this embodiment includes a rotating motor 81, a third threaded rod 82, a screw sleeve 83, a sliding rod 84 and a sliding sleeve 85. The rotating motor 81 is fixed to the top of the right side of the right fixed plate 3, and the two ends of the third threaded rod 82 are respectively rotatably connected to the top between the opposite sides of the two fixed plates 3 through bearings. The screw sleeve 83 is threadedly connected to the third threaded rod 82. The rotation of the third threaded rod 82 causes the screw sleeve 83 threadedly connected on its surface to move. The two ends of the sliding rod 84 are respectively fixed to the top between the opposite sides of the two fixed plates 3 and on the upper side of the third threaded rod 82, and the sliding sleeve 85 is slidably connected to the sliding rod 84.

[0040] In this embodiment, the output shaft of the rotating motor 81 passes through the right side fixed plate 3 and extends to the left side of the right side fixed plate 3 and is fixed to the third threaded rod 82.

[0041] It can be understood that the movement of the sleeve 83 drives the sliding sleeve 85 to slide on the outer surface of the sliding rod 84, thereby limiting the movement of the sleeve 83. The movement of the sleeve 83 drives the press 6 to move until it is adjusted to a suitable position. Then the press 6 is started, and the pressure rod of the press 6 drives the pressing plate 7 to move. The pressing plate 7 straightens the position of the profile to be straightened, thereby realizing the straightening of the profile.

[0042] The working principle of the above embodiment is:

[0043] (1) In order to clean the surface of the profile, first place the profile on the workbench 1, then start the electric push rod, the output shaft of the electric push rod moves and drives the clamping plate to move, and then the relative movement of the two clamping plates can position the profile, then turn the handle to make the second threaded rod 525 rotate and move downward, the movement of the second threaded rod 525 drives the moving plate 526 and the cleaning plate 54 to move downward until the lower surface of the cleaning plate 54 contacts the upper surface of the profile, stop rotating the second threaded rod 525, start the drive motor 522, the output shaft of the drive motor 522 rotates, and then drives the first threaded rod 521 to rotate, the rotation of the first threaded rod 521 causes the sliding block 523 threadedly connected to its surface to move, the movement of the sliding block 523 drives the fixed block 524 to move, and drives the moving plate 526 and the cleaning plate 54 to move through the second threaded rod 525, the movement of the cleaning plate 54 can clean the surface of the profile.

[0044] (2) In order to facilitate the straightening of different positions on the surface of the profile, the rotating motor 81 is started, and the output shaft of the rotating motor 81 rotates, thereby driving the third threaded rod 82 to rotate. The rotation of the third threaded rod 82 causes the screw sleeve 83 threadedly connected to its surface to move. The movement of the screw sleeve 83 drives the sliding sleeve 85 to slide on the outer surface of the sliding rod 84, thereby limiting the movement of the screw sleeve 83. The movement of the screw sleeve 83 drives the press 6 to move until it is adjusted to a suitable position. Thereafter, the press 6 is started, and the pressure rod of the press 6 drives the pressing plate 7 to move. The pressing plate 7 straightens the position of the profile to be straightened, thereby achieving the straightening of the profile.
