Embodiment Construction
[0038] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0039] refer to Figure 3-Figure 6 , this embodiment provides a point-to-point glue-free composite embossed toilet paper production process, using embossing equipment for embossing;
[0040] The embossing equipment includes a controller, unwinding equipment, a first traction roller 3, a first tension pulley 4, a first embossing device, a second traction roller 8, a second tension pulley 9 and a second embossing device . Described unwinding equipment comprises unwinding roller 1 and is used to drive the unwinding motor 16 of unwinding roller ( image 3 The unwinding motor 16 is not shown in the figure, but those skilled in the art should understand the connection mode between the unwinding motor 16 and the unwinding roller 1).
[0041] The first embossing device includes a first electric eye 8, and a first embossing steel roller 6 and a first embossi...

The invention relates to a production process of point-to-point glue-free composite embossed toilet paper. The production process comprises the following steps of step 1, unwinding a toilet paper rollat a rated unwinding linear speed V<0>; step 2, dividing the toilet paper roll into a first toilet paper layer and a second toilet paper layer; step 3, dragging the first toilet paper layer to a first embossing device for embossing to form upper-layer embossed toilet paper, and controlling the embossing linear speed V<2> of the upper-layer embossed toilet paper with a controller, and then dragging the second toilet paper layer to a second embossing device for embossing to form lower-layer embossed toilet paper, and controlling the embossing linear speed V<3> of the lower-layer embossed toiletpaper with the controller, the upper-layer embossed toilet paper and the lower-layer embossed toilet paper are input between a first embossed steel roller and a second embossed steel roller to be pressed to form multi-layer composite embossed toilet paper, and embossed patterns on the upper-layer embossed toilet paper and embossed patterns on the lower-layer embossed toilet paper are located at the same position and are mirror images of each other; and step 4, automatically adjusting V<1>, V<2> and V<3> to be kept at V<0> with the controller. According to the production process, the thicknessand bulkiness of the toilet paper can be improved.
Description
technical field [0001] The invention relates to a toilet paper production process, in particular to a point-to-point glue-free composite embossed toilet paper production process. Background technique [0002] Toilet paper is mainly used for people's daily hygiene, and is one of the indispensable paper types for the people. Generally speaking, toilet paper has a multi-layer composite structure, and the surface of the toilet paper is embossed by embossing equipment to increase the aesthetics of the toilet paper; more importantly, the embossing on the surface of the toilet paper can prevent the layers of the toilet paper from spreading; and increase the durability of the paper towel Surface area, which in turn allows toilet paper to have better cleaning power. [0003] Such as figure 1 Shown is the existing embossing equipment, including an upper embossing roll 100 and a lower embossing roll 200, and the upper embossing roll 100 and the lower embossing roll 200 are relatively...
