The leveling roller 125 is sleeved on the circumferential surface of the connecting rod 122 away from one end of the connecting shaft 124, and the moving rod 126 slides through the left and right walls of the connecting rod 122. The movement of the leveling roller 125 can effectively stretch and level the package to be detected to both sides, thereby improving the leveling effect of the thinner package to be detected, and avoiding the wrinkles on the surface of the thinner package to be detected from piling up when squeezing, thereby affecting the accuracy of the detection.

[0031] The end of the connecting rod 122 away from the fixed rod 121 is rotatably connected to the connecting shaft 124, and a second slide groove is provided on the side of the leveling roller 125 close to the moving rod 126. The end of the moving rod 126 close to the leveling roller 125 is in contact with the second slide groove.

The vertical rod 135 slides through the upper and lower walls of the baffle 132. The stopper 136 is fixedly installed below the detection plate 7. The baffle 132 moves upward to squeeze the No. 3 spring 137. The No. 3 spring 137 is squeezed to achieve buffering of the leveling device, so as to avoid the leveling roller 125 directly contacting and colliding with the package to be detected and causing damage to it, thereby maintaining the stability of the leveling device.

[0034] A sliding groove three is provided on one side of the movable plate 134 close to the baffle plate 132 , and the baffle plate 132 is fixedly installed inside the sliding groove three. The movable plate 134 is slidably connected to the movable block 131 , and the movable plate 134 moves up and down to drive the baffle plate 132 to move up and down.

Accuracy, at the same time, the leveling roller 125 will rotate during the process of contacting the package to be inspected and moving. The leveling roller 125 rotates and moves toward the two sides close to the connecting shaft 124 under the action of the spiral groove on the surface of the connecting shaft 124.

After the inspection is completed, the contraction of the No. 2 spring 127 drives the moving rod 126 to reset, and the moving rod 126 resets and drives the leveling roller 125 to reset, so as to avoid affecting subsequent inspections and reduce subsequent maintenance costs.

[0037] When the leveling roller 125 contacts the package to be inspected, it moves upward. The upward movement of the leveling roller 125 drives the connecting shaft 124 to rotate counterclockwise around the sliding block 123. The rotation of the connecting shaft 124 drives the supporting rod 133 to move upward. The upward movement of the supporting rod 133 drives the moving plate 134 to move upward. The upward movement of the moving plate 134 drives the baffle 132 to move upward. The baffle 132 moves upward to squeeze the No. 3 spring 137. The No. 3 spring 137 is squeezed to buffer the leveling roller 125, so as to prevent the leveling roller 125 from directly contacting the package to be inspected and causing collision and damage to the package, thereby maintaining the stability of the leveling device. At the same time, the connecting shaft 124 moves in the direction away from the fixed rod 121 with The movable support rod 133 moves in the direction close to the stop block 136, and the movement of the support rod 133 drives the movable plate 134 to move. The movable plate 134 contacts the stop block 136 and moves upward under its action. The upward movement of the movable plate 134 drives the support rod 133 to move upward. The upward movement of the support rod 133 drives the connecting shaft 124 to rotate counterclockwise around the sliding block 123.
