Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adult diaper production, and more specifically to an improved rotary cutting tool holder for adult diapers. Background Art
[0002] At present, most of the diapers produced in China are in the shape of "I". During production, it is necessary to cut out arc-shaped grooves at the transverse two sides along the conveying direction of the continuously conveyed material, so as to form diapers in the shape of "I" after cutting. The existing rotary cutting device, as shown in the attached Figure 1 description, includes a tool holder, two upper bearing seats, two lower bearing seats, a cutter roller and a bottom roller. The tool holder includes a front support plate, a rear support plate and a cross beam surrounding a square frame. Square through holes are cut in the middle of the front surfaces of the front support plate and the rear support plate for the material to pass through. It is defined that the direction extending along the length of the front support plate is the transverse direction, and the direction extending along the cross beam is the longitudinal direction. The two lower bearing seats are respectively fixedly arranged at the transverse two ends of the tool holder and located between the front support plate and the rear support plate. The transverse two ends of the bottom roller are respectively arranged on the lower bearing seats through bearings. The two upper bearing seats are respectively fixedly arranged on the upper sides of the two lower bearing seats. The transverse two ends of the cutter roller are respectively arranged on the upper bearing seats through bearings. The existing rotary cutting device has a disadvantage: both the cutter roller and the bottom roller are solid structures, and their weights are relatively large. Taking the rotary cutting device for adult pull-up pants as an example, the weight of its cutter roller is about 490 kg, and the weight of the bottom roller is about 390 kg. The transverse two ends of the bottom roller are respectively supported by bearings on the lower bearing seats, and the middle part is in a suspended state. When the speed of the bottom roller is relatively high, its centrifugal force is large, and during cutting, since the cutter roller will generate a downward pressure on the bottom roller, the bottom roller is prone to flexural deformation after long-term use, affecting its service life and the wear of other parts. In response to this, the inventor has proposed an improved rotary cutting tool holder for adult diapers, dividing the cutter roller into two sections and adding two fixing seats in the middle to increase the bearing capacity of the cutter roller and effectively reduce the downward pressure generated by the cutter roller on the bottom roller.
[0003] In order to solve the problems that the cutter roller is heavy and the cutter roller will generate a downward pressure on the bottom roller during cutting, which is prone to cause flexural deformation of the bottom roller after long-term use, Chinese Patent (Authorization Publication No.: CN114347133A) discloses an adult diaper rotary cutting device, which includes a tool holder, a cutter roller, a bottom roller, two upper bearings and a support seat. The axial two ends of the cutter roller are arranged on the machine frame through the two upper bearings. The bottom roller is distributed below the cutter roller. The axial two ends of the bottom roller are arranged on the tool holder. The middle part of the bottom roller is connected to the tool holder through the support seat. The support seats are distributed at the axial middle part of the bottom roller. This invention makes the bottom roller form two independent support areas through the support seats, and each of the support areas cooperates with the cutter roller to work.
[0004] There are still some deficiencies in the application of this solution. Since the biggest factor causing the deformation of the bottom roller comes from the downward pressure exerted by the cutter roller on the bottom roller, if no effective pressure reduction improvement is made to the cutter roller, the problem of the bottom roller being pressed and deformed will still occur. At the same time, during actual use, due to the long distance of the cutter roller, the problem of inconsistent rotary cutting forces on the left and right sides will occur after long-term use, resulting in poor rotary cutting quality. Therefore, it is necessary to improve the structure of the rotary cutting tool holder so that it can perform rotary cutting better, effectively avoid the wear and deformation of machine components, and extend the service life.
