As shown in Figures 1 to 2, an embodiment of the present utility model provides a tipping paper overlapping device. The tipping paper lapping device includes a base 1 and a lapping roller 2. The base 1 is provided with a movable support bracket 11 .

The overlapping roller 2 is a hollow cylinder, and the outer surface of the overlapping roller 2 is provided with textured knurling. The support bracket 11 is connected to the overlap roller 2, and the support bracket 11 is used to drive the overlap roller 2 to squeeze the tipping paper.

The overlapping rollers 2 include at least two, and the central axes of the two overlapping rollers 2 are on the same plane as the center perpendicular of the base 1 . The difference between the working distance of the two overlapping rollers 2 and the sum of the thicknesses of the tipping paper to be overlapped and the adhesive layer is 0.05-0.07mm.

The utility model provides a movable support bracket 11 on the base 1 and at least two overlapping rollers 2. The at least two overlapping rollers 2 are connected to the support bracket 11, and are provided on the outer surface of each overlapping roller 2. The textured knurling increases the contact area and friction between the overlapping roller 2 and the tipping paper, preventing the overlapping roller 2 from sliding relative to the tipping paper when squeezing the tipping paper, thereby improving the success rate of overlapping.

In addition, the central axes of the two overlapping rollers 2 and the mid-perpendicular line of the base 1 are set on the same plane, so that the working distance of the two overlapping rollers 2 is equal to the thickness of the tipping paper to be overlapped and the adhesive layer. The difference between If the difference between the sum of the thicknesses is too large or too small, it will cause the tipping paper to wrinkle, break or be weakly bonded, affecting the quality of the product and even causing equipment shutdown, affecting the operating efficiency of the equipment.

In this embodiment, the working distance of the overlapping rollers 2 refers to the minimum distance between the two overlapping rollers 2 during the working process, that is, on the plane where the central axes of the two overlapping rollers 2 are located, the outer surfaces of the two overlapping rollers 2 spacing between.

The difference between the working distance of the two overlapping rollers 2 and the sum of the thicknesses of the tipping paper to be overlapped and the adhesive layer is an absolute value.

In one embodiment of the tipping paper lapping device of the present invention, the difference between the working distance of the two lapping rollers 2 and the sum of the thicknesses of the tipping paper to be overlapped and the adhesive layer is 0.06 mm, the working distance between the two overlapping rollers 2 is 0.08mm.

It should be noted that in this embodiment, the thickness of the tipping paper is 0.05mm, and the thickness of the adhesive layer is 0.04mm. That is, the thickness of two pieces of tipping paper and the adhesive layer is 0.14mm. When the difference between the working distance of the two overlapping rollers 2 and the sum of the thicknesses of the tipping paper and the adhesive layer to be overlapped is 0.06mm, that is, when the overlapping work is performed, the two overlapping rollers 2 The working distance is 0.08mm, and the two overlapping rollers 2 compress the new and old tipping paper and the adhesive layer by 0.06mm. This arrangement ensures the firmness of the bonding between the old and new tipping paper, and avoids the situation where the old and new tipping paper is not tightly bonded, wrinkles or breaks, thereby reducing the operating efficiency of the equipment.

It should also be noted that the distance between the outer surfaces at the central axes of the two overlapping rollers 2 is not likely to be too large or too small. When the difference between the working distance of the two overlapping rollers 2 and the sum of the thicknesses of the tipping paper to be overlapped and the adhesive layer is too large, the two overlapping rollers 2 will squeeze the old and new tipping paper and The extrusion amount of the adhesive layer increases, which in turn causes the tipping paper to wrinkle or break, affecting the quality of the product, and even causing equipment shutdown and affecting the operating efficiency of the equipment.

When the difference between the working distance of the two overlapping rollers 2 and the sum of the thicknesses of the tipping paper and the adhesive layer to be overlapped is too small, the two overlapping rollers 2 will squeeze the old and new tipping paper and the adhesive layer. The extrusion amount of the laminate is reduced, which leads to the weak bonding between the old and new tipping paper.

In order to ensure the successful overlapping of old and new tipping paper in this utility model and the smooth movement of the tipping paper, when installing the overlapping roller 2, it is necessary to check whether there are burrs on the surface of the overlapping roller 2. If there are burrs on the surface of the overlapping roller 2, the surface of the overlapping roller 2 needs to be polished to prevent the burrs on the surface of the overlapping roller 2 from puncturing the tipping paper and reducing the product quality. If the surface of the overlapping roller 2 has no burrs, just install the overlapping roller 2 directly.

Optionally, the modulus M of the textured knurling is 0.3mm.

The utility model sets the modulus M of the knurling on the surface of the overlapping roller 2 to 0.3mm, which makes the knurling pattern on the surface of the overlapping roller 2 thicker and further increases the friction between the overlapping roller 2 and the tipping paper. force, further improving the success rate of overlapping.

Optionally, bearings (not shown in the figure) are provided at both ends of the overlapping roller 2 , and the bearings are connected to the support bracket 11 .

The diameter of the hollow portion 22 first extends from one end of the overlapping roller 2 to remain unchanged, then extends to an increasing diameter, and then extends to the other end of the overlapping roller 2 to decrease in diameter. This arrangement enables the bearings to be stably installed at both ends of the hollow portion 22 of the overlapping roller 2 and prevents the bearings from running in the hollow portion 22 of the overlapping roller 2 along the axial direction of the overlapping roller 2 .

It should be noted that the diameters of both ends of the hollow portion 22 can be adapted accordingly according to the diameter of the bearing.
