[0034] like Figure 1-4 As shown, the utility model provides a composite film printing quality detection device, which has a workbench 1, on which a detection mechanism 11 is fixedly installed, wherein both left and right ends of the detection mechanism 11 are fixedly installed with a conveying component, and a leveling component is provided between the detection mechanism 11 and the conveying component on the left side;

[0035] The conveying assembly includes a subframe 2 fixedly mounted on a workbench 1, a driving roller 21 is rotatably mounted in the subframe 2, and a height-adjustable driven roller 22 is disposed directly above the driving roller 21;

[0036] The leveling assembly includes a main frame 3 slidably mounted on the workbench 1, a support platform 31 is fixedly mounted on the inner bottom wall of the main frame 3, and a lower pressing plate 32 with adjustable height is arranged directly above the support platform 31;

[0037] A slideway 12 is transversely provided in the middle of the workbench 1 , and a slider 37 is fixedly mounted on the bottom wall of the main frame 3 , and the slider 37 is slidably connected in the slideway 12 .

[0038] Optionally, in the above technical solution, a main telescopic cylinder 33 is fixedly installed in the middle of the top wall of the main frame 3, the movable end of the main telescopic cylinder 33 passes through the top wall of the main frame 3 and extends downward, and a horizontal plate 34 is fixedly installed at the movable end of the main telescopic cylinder 33.

[0039] Optionally, in the above technical solution, upper ends of springs 35 are fixedly connected to both sides of the transverse plate 34 , and lower ends of the two springs 35 are fixedly connected to both sides of the lower pressure plate 32 .

[0040] Optionally, in the above technical solution, a telescopic rod 36 is fixedly connected to the middle of the transverse plate 34 , and a movable end of the telescopic rod 36 extends downward and an end portion is fixedly connected to the middle of the lower pressing plate 32 .

[0041] Optionally, in the above technical solution, the left inner wall of the slide 12 is rotatably connected with a screw rod 13 , and the right inner wall of the slide 12 is fixedly installed with a rotary motor 14 , and the output shaft of the rotary motor 14 is fixedly connected to the screw rod 13 .

[0042] Optionally, in the above technical solution, a threaded hole is opened on the slider 37, and the slider 37 is sleeved on the outer periphery of the slideway 12 and threadedly connected thereto.

[0043] Optionally, in the above technical solution, a secondary telescopic cylinder 23 is fixedly installed in the middle of the top wall of the secondary frame 2, the movable end of the secondary telescopic cylinder 23 passes through the top wall of the secondary frame 2 and extends downward, the movable end of the secondary telescopic cylinder 23 is fixedly connected to the inner frame 24, and both ends of the driven roller 22 are rotatably connected in the inner frame 24.

[0044] A driving motor 20 is fixedly mounted on the outer wall of the sub-frame 2, and an output shaft of the driving motor 20 passes through the side wall of the sub-frame 2 and is fixedly connected to the active roller 21 to drive the active roller 21 to rotate, thereby moving the composite film.

[0045] The highest point of the support platform 31 and the highest end of the active roller 21 are located on the same horizontal plane, so that the movement of the composite film remains horizontal and the downward pressure of the driven roller 22 makes it easier to straighten the composite film.

[0046] The bottom wall of the main frame 3 abuts against the top wall of the workbench 1, so that the sliding of the main frame 3 is more stable; the forward or reverse rotation of the rotary motor 14 can move the main frame 3 left and right.

[0047] Among them, two limit columns 30 are symmetrically installed on the top of the cross plate 34 about the main telescopic cylinder 33. The limit columns 30 penetrate the top wall of the main frame 3 and are slidably connected thereto, so that the movement of the lower pressure plate 32 is more stable and deviation is prevented.

[0048] Working principle:

[0049] When in use, the composite film is first passed through the active rollers 21 and the driven rollers 22 on both sides and between the support platform 31 and the lower pressing plate 32 of the main frame 3 in sequence, that is, the composite film is attached to the support platform 31 and the active rollers 21;

[0050] When the composite film is uneven or folded, the auxiliary telescopic cylinder 23 is first started to push the inner frame 24 downward, so that the driven roller 22 is pressed on the active roller 21, that is, the two parts of the composite film are pressed down, so that the composite film is in a straight state;

[0051] Then, the main telescopic cylinder 33 is started to drive the horizontal plate 34 to move downward, so that the lower pressing plate 32 squeezes the composite film, and the main frame 3 moves horizontally, driving the support platform 31 and the lower pressing plate 32 to move left and right relative to the composite film, further improving the leveling effect;

[0052] When the leveling is completed, the auxiliary telescopic cylinder 23 and the main telescopic cylinder 33 are reset. At this time, the composite film is not squeezed, and the drive motor 20 is started to drive the active roller 21 to rotate, so that the flat composite film is moved to the bottom of the detection mechanism 11 for detection. After the detection is completed, the drive motor 20 is started again to drive the composite film to continue to move right away from the bottom of the detection mechanism 11. In this way, the composite film detected by the detection mechanism 11 can avoid the presence of uneven parts.

[0053] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
