The outer sliding sleeve of the movable frame 24 is provided with at least one guide sleeve 29, and the guide sleeve 29 is fixedly connected to the second supporting frame 4. The locking unit includes a fixed plate 31 contacting and arranged at the bottom of the lifting plate 19, the fixed plate 31 is fixedly connected to the first supporting frame 3, and at least two guide columns 32 are fixedly connected to the top of the fixed plate 31, and the guide columns 32 penetrate the lifting plate 19, and the top of the lifting plate 19 is contacted with a support bar 34, and the fixed plate 31 is provided with a reset member adapted to the support bar 34, and the reset member includes a second movable plate 33 fixedly installed on the side of the support bar 34 away from the first supporting frame 3, and a sliding groove 36 is provided on the side of the fixed plate 31 away from the first supporting frame 3, and a slide plate 35 is slidably provided in the slide groove 36, and the slide plate 35 and the inner wall of the slide groove 36 are connected by a tension spring 37, and the slide plate 35 and the second movable plate 33 are fixedly connected;

[0040] Before installing the rotating shaft 6 and the leveling roller 7 on the first support frame 3 and the second support frame 4, the second support part 28 and the movable frame 24 are driven to slide relative to the second support frame 4 and the guide sleeve 29 through the first hydraulic telescopic rod 27.

Then the staff installs several rotating shafts 6 and leveling rollers 7 on the first support frame 3 and the second support frame 4 respectively. When the protective shell 13 is installed on the second support frame 4, the fourth tooth plate 30 on the protective shell 13 is meshed with the gear 23, reducing the possibility of the gear 23 and the screw rod 20 rotating relative to the second support frame 4 due to non-human factors. When the wound aluminum material is used up, it needs to be replaced with a new one. When aluminum material is used, the staff drives the second movable plate 33 to move, and the second movable plate 33 drives the slide plate 35 and the support bar 34 to move synchronously. The tension spring 37 is in a stretched state, and the support bar 34 no longer contacts the top of the lifting plate 19, thereby releasing the limitation on the position of the lifting plate 19 and the second support frame 4.

[0042] The staff drives the rotating seat 2 to move horizontally relative to the operating table 1, and the rotating seat 2 drives the supporting plate 40 to move under the operating table 1 through the fixed column 38, so that the orientation of the rotating seat 2 and the leveling roller 7 is in a preset position. When there is no need to adjust the position of the rotating seat 2 and the leveling roller 7, the first pressing plate 43 is driven to move up by the second hydraulic telescopic rod 42, so that the first pressing plate 43 presses the bottom of the supporting plate 40, so that the supporting plate 40 and the rotating seat 2 can be fixed relative to the operating table 1. According to the width of the aluminum plate, the staff drives the movable seat 47 and the correction wheel 48 to slide relative to the guide plate 45 and the first support frame 3 to change the distance between the two movable seats 47.

The positions of both sides of the aluminum plate are corrected by the four correction wheels 48 to avoid tilting and shaking during the leveling process of the aluminum plate, so that the leveling effect is better.

[0043] A method for processing and leveling a car license plate in this embodiment uses the above-mentioned car license plate processing and leveling device, and includes the following steps:

[0044] Step 1: The staff passes the aluminum plate between the first support frame 3 and the second support frame 4, and then drives the second support frame 4 to move downward through the spacing adjustment mechanism, so that the spacing between the second support frame 4 and the first support frame 3 is at a preset value;

[0045] Step 2: The staff places a plurality of rotating shafts 6 and leveling rollers 7 on the first support frame 3 and the second support frame 4 respectively, and the guide blocks 9 on the first movable plate 8 slide into the corresponding guide grooves 5;

[0046] Step three: Use the positioning structure to locate the positions of the two adjacent first movable plates 8 in the vertical direction, complete the installation and correction of the leveling roller 7, and when the aluminum plate moves between the first support frame 3 and the second support frame 4, the aluminum plate is leveled by the two adjacent leveling rollers 7 in the vertical direction.

[0047] Working principle: the staff passes the aluminum plate between the first support frame 3 and the second support frame 4, and then drives the second support frame 4 to move downward through the spacing adjustment mechanism, so that the spacing between the second support frame 4 and the first support frame 3 is at a preset value, and the staff respectively places a number of rotating shafts 6 and leveling rollers 7 on the first support frame 3 and the second support frame 4, and the guide block 9 on the first movable plate 8 slides into the corresponding guide groove 5, and the position of the two adjacent first movable plates 8 in the vertical direction is positioned by the positioning structure, and the installation and correction of the leveling roller 7 are completed. When the aluminum plate moves between the first support frame 3 and the second support frame 4, the aluminum plate is leveled by the two adjacent leveling rollers 7 in the vertical direction. The spacing between the two adjacent leveling rollers 7 in the vertical and horizontal directions can be adjusted according to actual needs, and it is convenient to increase or decrease the leveling roller 7, which improves convenience and makes the leveling effect better;

[0048] The staff drives the support plate 10 and the positioning plate 11 to move in the vertical direction, so that the positioning plate 11 passes through two adjacent positioning holes 12 in the vertical direction, thereby positioning the positions of the two adjacent rotating shafts 6 and the first movable plate 8 in the vertical direction. The staff drives the support plate 10 and the positioning plate 11 to move in the horizontal direction, and the first movable plate 8 can drive the guide block 9 to move in the horizontal direction, thereby adjusting the distance between the two adjacent leveling rollers 7 in the horizontal direction. When the position of the leveling roller 7 in the horizontal direction is adjusted, the staff drives the protective shell 13 to move to the top of the second support frame 4, and The first mounting plate 16 and the second mounting plate 17 are fixedly connected together by bolts 18, and the second tooth plate 15 on the protective shell 13 is meshed with the first tooth plate 14 to prevent the leveling roller 7 and the rotating shaft 6 from shaking in the horizontal direction relative to the first support frame 3 and the second support frame 4. When the second support frame 4 moves in the vertical direction relative to the first support frame 3, the positioning plate 11 and the first movable plate 8 located above follow the second support frame 4 to move upward, and the positioning plate 11 slides relative to the first movable plate 8 located below, and the vertical movement of the second support frame 4 will not cause the leveling roller 7 to shake in the horizontal direction;

[0049] Before installing the rotating shaft 6 and the leveling roller 7 on the first support frame 3 and the second support frame 4, the second support part 28 and the movable frame 24 are driven to slide relative to the second support frame 4 and the guide sleeve 29 through the first hydraulic telescopic rod 27. The guide sleeve 29 is designed to make the movable frame 24 move smoothly in the horizontal direction, and the movable frame 24 drives the screw rod 20 to rotate through the third tooth plate 25 and the gear 23, and the screw rod 20 can move vertically relative to the lifting plate 19 to change the distance between the second support frame 4 and the first support frame 3. Then the staff installs several rotating shafts 6 and leveling rollers 7 on the first support frame 3 and the second support frame 4 respectively. When the protective shell 13 is installed on the second support frame 4, the fourth tooth plate 30 on the protective shell 13 is meshed with the gear 23, reducing the possibility of the gear 23 and the screw rod 20 rotating relative to the second support frame 4 due to non-human factors. When the wound aluminum material is used up, it needs to be replaced with a new one. When the lifting plate 19 is lowered to the bottom, the staff member releases the second movable plate 33, and the second movable plate 33 drives the slide plate 35 and the support bar 34 to move synchronously. The tension spring 37 is in a tensioned state, and the support bar 34 is no longer in contact with the top of the lifting plate 19, thereby releasing the limitation on the position of the lifting plate 19 and the second support frame 4. The staff member drives the lifting plate 19 and the second support frame 4 to move upward, and the lifting plate 19 slides relative to the guide column 32. When the bottom horizontal position of the lifting plate 19 is higher than the top horizontal position of the support bar 34, the staff member releases the second movable plate 33, and the tension spring 37 drives the slide plate 35 and the second movable plate 33 to slide in the opposite direction, so that the support bar 34 moves to the bottom of the lifting plate 19, and the lifting plate 19 and the second support frame 4 are supported by the support bar 34, thereby increasing the distance between the second support frame 4 and the first support frame 3, so as to facilitate the new aluminum plate to pass through between the first support frame 3 and the second support frame 4.

[0050] The staff drives the rotating seat 2 to move horizontally relative to the operating table 1, and the rotating seat 2 drives the supporting plate 40 to move under the operating table 1 through the fixed column 38, so that the orientation of the rotating seat 2 and the leveling roller 7 is in a preset position. When there is no need to adjust the position of the rotating seat 2 and the leveling roller 7, the first pressing plate 43 is driven to move up by the second hydraulic telescopic rod 42, so that the first pressing plate 43 presses the bottom of the supporting plate 40, so that the supporting plate 40 and the rotating seat 2 can be fixed relative to the operating table 1. According to the width of the aluminum plate, the staff drives the movable seat 47 and the correction wheel 48 to slide relative to the guide plate 45 and the first support frame 3 to change the distance between the two movable seats 47. After the position of the movable seat 47 is adjusted, the second pressing plate 51 is driven to move up by the third hydraulic telescopic rod 50, so that the second pressing plate 51 presses the bottom of the movable seat 47, so that the movable seat 47 can be fixed relative to the second pressing plate 51 and the first support frame 3. The positions of both sides of the aluminum plate are corrected by the four correction wheels 48 to avoid tilting and shaking during the leveling process of the aluminum plate, so that the leveling effect is better.
