Description

Heavy-duty nylon roller Technical Field The utility model relates to the technical field of nylon roller production, in particular to a heavy-duty nylon roller. Background In the textile calendaring production line, the fabric post-finishing process is carried out, and the surface of the fabric is leveled by utilizing the physical plasticity of the fiber under the high pressure or high temperature condition so as to improve the luster of the fabric. Different cloth cover effects can be obtained according to the roller surface materials, the rolling pressure and the temperature of the roller and through the matching of different soft and hard rollers and cloth penetrating modes. The production line of textile, the whole line produces various specification breadth fabrics, because of the different fabric calendering demands, some fabrics require tension force big, are stressed heavy, use solid steel roller and nylon roller to press in the actual production process, the bearing force is big, and the finished product surface has the flaw phenomenon easily. The nylon sleeve of the nylon roller cannot be heated too high in order to prolong the service life of the nylon roller, so that the existing hollow structure without support in the roller core of the nylon roller can be used only on low-pressure calendaring equipment, cannot meet the high-tonnage pressure calendaring requirement, and the roller body can be broken after bearing pressure exceeds 80 tons. In order to strengthen the pressure bearing capacity of the roller body, the prior improved technology of the nylon roller is to add a steel pipe structure in the roller body. The structure of the seamless steel tube with the two ends of the nylon roller core and the shaft heads adopts a groove welding structure, so that the stress is reduced, but in textile production lines, the phenomena of cracking and breaking at the root parts of the shaft heads when the nylon roller core is used for a long time and subjected to high pressure still exist. Moreover, the circulation of cooling water of the cooling structure in the existing nylon roller is slower, the overall cooling effect of the roller body is poorer, the roller surface of the nylon roller is easy to damage, and the cooling structure is also a factor influencing the service life of the nylon roller. In summary, a further improvement on the structure of the nylon roller is needed to solve the problem of short service life of the nylon roller. Disclosure of utility model The utility model aims to provide a heavy-duty nylon roller, which can prolong the service life of the nylon roller and improve the bearing capacity of a roller body. In order to achieve the aim, the utility model provides a heavy-duty nylon roller, which comprises a roller core, a shaft head, a steel pipe, a nylon sleeve and a flow guide assembly; The roller comprises a roller core, a shaft head, a water inlet, a water outlet, a water inlet and a water outlet, wherein a flow channel is arranged in the roller core along an axis, and the roller core is provided with a transmission groove; the steel pipe is coaxially arranged outside the roller core, a flow guide component is arranged on the outer wall of the roller core, and the flow guide component is positioned between the steel pipe and the roller core; The guide assembly comprises two connecting parts and a plurality of connecting ribs, the two connecting parts are positioned on the outer wall of the roller core, the plurality of connecting ribs are distributed between the two connecting parts in a ring-shaped array mode, the gap of each connecting rib is a guide channel, the connecting parts are provided with a plurality of transmission holes, and the transmission holes are communicated with the guide channels; The nylon sleeve is coaxially arranged on the outer wall of the steel pipe. Preferably, the number of the transmission grooves is a plurality of. Further, the conveying grooves are staggered at the end part of the roller core. As a further improvement of the utility model, the steel pipe is hot sleeved outside the roller core. As a further improvement of the utility model, the number of the diversion channels is 6. As a further improvement of the utility model, connecting plates are arranged at two ends of the steel pipe through fasteners, and the nylon sleeve is positioned between the two connecting plates. Compared with the prior art, the heavy-duty nylon roller has the advantages that: (1) The shaft head cancels the traditional welding mode, adopts the integrated round steel forging shaft head, reduces the processing stress, and avoids the phenomenon that the shaft head is pressed at the welding position or the root of the shaft head is cracked and broken; (2) The cooling water can circulate in the roller core rapidly, the roller body can cool rapidly, the service life of the roller body can be prolonged, and the surface abrasion of the nylon sleeve can be delayed.
