The installation shell 4 is provided with a first chute 42, the first disc 90 is slidably installed in the first chute 42, the installation shell 4 is provided with a second chute 43, the tail end of the first connecting rod 244 is slidably installed in the second chute 43, one end of the first connecting rod 244 is installed in the second chute 43, one end of the lower roller 24 is installed in the second chute 231, and friction in the first chute 203 when the lower roller 24 moves can be reduced. The third spout 44 has been seted up on the installation shell 4, the blind hole has been seted up to the one side of third spout 44, the bottom fixed mounting of blind hole has spring 45, the terminal fixed mounting of spring 45 has baffle 46, baffle 46 offsets with first sleeve 92, make first sleeve 92 when loop bar 91 drives the removal, first sleeve 92 extrusion baffle 46, baffle 46 extrusion spring 45 to make first sleeve 92 can not take place to deflect when removing, reduce the wearing and tearing to first sleeve 92. The mounting shell 4 is fixedly provided with a plurality of first connecting lugs 41, and the first connecting lugs 41 are fixed on the mounting frame 21 through screws, so that the mounting shell is convenient and quick. The mounting cover 3 is mounted on the mounting shell 4, the third through groove 32 is formed in the position, corresponding to the screw rod 71, of the mounting cover 3, and the screw rod 71 is prevented from being blocked during mounting through the third through groove 32. A plurality of second engaging lugs 31 are fixedly mounted on the mounting cover 3, and the second engaging lugs 31 are fixed on the mounting frame 21 through screws, so that foreign matters such as external dust are prevented from entering the screw rod 71, and the precision of the screw rod 71 is further influenced.

In this embodiment, before use, the screw rod 71 is driven to rotate by rotating the adjusting cap 7, the screw rod 71 drives the second connecting rod 253 to move along the first chute 201, the second connecting rod 253 drives the upper roller 25 to move, the second connecting rod 253 drives the loop bar 91 to move, the loop bar 91 drives the first sleeve 92 to move, the first sleeve 92 drives the first connecting rod 244 to move, and the first connecting rod 244 drives the lower roller 24 to move, so that the distance between the upper roller 25 and the lower roller 24 can be adjusted conveniently and quickly; through the matching of the pointer 701 and the dial 6, the moving length distance of the upper roller 25 and the lower roller 24 can be directly read, and further the relative downward moving distance of the upper roller 25 can be obtained; the second motor 17 is started, the second motor 17 drives the driving belt 8 to rotate, gear teeth on the driving belt 8 drive the first gear 241 to rotate, the first gear 241 drives the lower roller 24 to rotate, the first gear 241 is meshed with the second gear 242, the second gear 242 is meshed with the third gear 252, the third gear 252 is meshed with the fourth gear 251, so that the upper roller 25 is driven to rotate, and the upper roller 25 and the lower roller 24 synchronously and reversely rotate;

starting the first motor 14, driving the transmission belt 13 to transmit through the belt 15 by the first motor 14, then placing the primarily folded white cardboard on the transmission belt 13 on the left side of the transmission belt 13, moving the white cardboard along with the transmission belt 13 until the folded part of the white cardboard enters between the lower roller 24 and the upper roller 25, and completing the ink explosion test on the white cardboard through extrusion of the lower roller 24 and the upper roller 25;

during the adjustment process, the first connecting rod 244 and the second connecting rod 253 are hinged through the first connecting frame 243 and the second connecting frame 254, the first gear 241 is meshed with the gear teeth on the transmission belt 8, the first gear 241, the second gear 242, the third gear 252 and the fourth gear 251 are sequentially meshed, when the second connecting rod 253 moves obliquely downwards under the action of the screw rod 71, the meshing relationship among the first gear 241, the second gear 242, the third gear 252 and the fourth gear 251 is not changed, namely when the distance between the lower roller 24 and the upper roller 25 is changed, synchronous movement with the same linear velocity and the opposite rotating direction can be still maintained between the lower roller 24 and the upper roller 25.

The white cardboard detection equipment for the cigarettes provided by the invention is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
