[0002] In the field of toilet paper production, with the increasing demand of consumers for product quality, multi-layer composite toilet paper gradually occupies a large market share with its better flexibility, water absorption and strength and other advantages. However, the production and processing process of multi-layer composite toilet paper, especially the slitting link, faces many technical challenges.

[0003] Traditional toilet paper slitting equipment mostly adopts single tensioning mode, aiming to provide a relatively constant tension for the paper web to ensure the smooth slitting. However, for multi-layer composite toilet paper, this single tensioning mode has serious defects. Since the material properties (such as fiber length, density, flexibility, etc.) of each layer of paper differ after compounding, the response of each layer of paper to external force is not consistent during the slitting process. For example, the inner layer paper may stretch and even break due to excessive tension, while the outer layer paper may appear loose wrinkles due to insufficient tension, which not only affects the appearance flatness of the product, but also reduces the overall quality of the product, resulting in high scrap rate. Therefore, we propose a multi-layer composite toilet paper slitting tension gradient control tensioning device to solve the above problems. SUMMARY

[0024] Further, it claims that the main assembly 2 comprises an assembly shell 201, both sides of the assembly shell 201 are fixedly connected with fixing frames 202, the surface of the assembly shell 201 is provided with a communication window 203, the assembly shell 201 is built-in with a first movement disc 204 and a second movement disc 205, the axis of the first movement disc 204 and the second movement disc 205 coincides, the end faces of the first movement disc 204 and the second movement disc 205 which are close to each other are provided with a plurality of ball grooves 206, the plurality of ball grooves 206 are uniformly distributed around the axis of the assembly shell 201, a plurality of tension rollers 207 are arranged between the first movement disc 204 and the second movement disc 205, both ends of the tension roller 207 are fixedly connected with connecting rods 208, one end of the connecting rod 208 away from the tension roller 207 is fixedly connected with a movement ball 209, the movement ball 209 is placed in the ball groove 206, the movement ball 209 is slidably connected with the inner wall of the ball groove 206, and the plurality of circumferentially distributed tension rollers 207 can exert tension on the multi-layer composite toilet paper from different directions, so that the tension on the paper during the slitting process is more uniform. Compared with the traditional single tensioning mode, the problems of inner layer paper stretching deformation, rupture and outer layer paper relaxation and wrinkling caused by excessive or insufficient local tension can be effectively avoided, and the appearance flatness and overall quality of the product are improved.

[0025] Further, the servo motor 210 is arranged on the side of the first motion disc 204 away from the second motion disc 205, the output end of the servo motor 210 is fixedly connected with the first motion disc 204, the surface of the servo motor 210 is sleeved with a fixing seat 211, one side of the fixing seat 211 is fixedly connected with the inner wall of the assembling shell 201, the second motion disc 205 is fixedly connected with a connecting roller 212 on the side away from the first motion disc 204, the end of the connecting roller 212 away from the second motion disc 205 is fixedly connected with a guide seat 213, the surface of the guide seat 213 is sleeved with a guide frame 214, the guide seat 213 is slidingly connected with the inner wall of the guide frame 214, the end of the guide frame 214 away from the second motion disc 205 is fixedly connected with the inner wall of the assembling shell 201, the multi-layer composite toilet paper enters the main tension assembly 2 and is wound around the plurality of tension rollers 207. When the servo motor 210 is not started, the first motion disc 204 and the second motion disc 205 keep the relative position, the plurality of tension rollers 207 exert a certain initial tension on the toilet paper, which plays a role of preliminary tensioning, when the servo motor 210 is started, the output end drives the first motion disc 204 to rotate. Since the first motion disc 204 and the second motion disc 205 are connected through the tension roller 207, the connecting rod 208 and the motion ball 209 and the ball groove 206, when the first motion disc 204 rotates, the end of the plurality of tension rollers 207 will be deflected. Because the motion balls 209 at both ends of the tension roller 207 are arranged in the ball grooves 206 of the first motion disc 204 and the second motion disc 205 respectively, the deflection makes the tension roller 207 pull the second motion disc 205 to be close to the first motion disc 204, at this time, the multi-layer composite toilet paper is further tensioned, the tension is increased, the first motion disc 204 reverses after rotating a certain angle or time, the second motion disc 205 is also restored to the initial position under the driving of the tension roller 207, at this time, the tension of the multi-layer composite toilet paper is reduced.

[0026] The plurality of circumferentially distributed tension rollers 207 can apply tension to the multi-layer composite toilet paper from different directions, compared with the traditional single tensioning mode, the tension applied to the paper during the slitting process is more uniform, effectively avoiding problems caused by excessive or insufficient local tension, since the tension can be uniformly controlled, the problems such as stretching deformation and fracture of the inner layer paper due to excessive local tension, and relaxation and wrinkling of the outer layer paper due to insufficient local tension can be effectively avoided, thereby improving the appearance flatness and overall quality of the product, the first movement disc 204 is periodically forward and reverse rotated by the servo motor 210, so that the tension roller 207 is in a moving state, realizing dynamic tension control. This dynamic tensioning mode can better adapt to the different needs of the paper during the slitting process, further improving the tensioning effect and slitting quality, because the defective products caused by the tension problem of the paper are effectively avoided, the downtime and rework caused by the quality problem of the paper are reduced, thereby improving the production efficiency and reducing the production cost.
