Description

Hot roller is used in production of medical hydrophilic non-woven fabrics Technical Field The utility model relates to the technical field of non-woven fabric production, in particular to a hot roller for producing medical hydrophilic non-woven fabric. Background The hydrophilic nonwoven has extremely strong liquid adsorption capacity and does not cause injury to human beings, so that it is often used for producing medical nonwoven dressings, diaper, kitchen wipes, sanitary napkins for girls and the like. When in production, the continuous heating of the non-woven fabric hot-pressing roller can lead to uneven temperature distribution of the hot-pressing roller, and the quality of non-woven fabric hot-pressing is affected. Because the length of the hot pressing roller is larger than the width of the non-woven fabric, heat in the area which is not contacted with the non-woven fabric can be transferred to the contact area, so that the temperature of the two sides of the hot pressing roller is higher, the middle temperature is lower, and a temperature curve similar to a ship shape is formed. The non-woven fabrics in the high-temperature areas on the two sides are easy to damage fiber structures due to excessive heating, the problems of uneven thickness, reduced strength and the like occur, and the product is easy to penetrate by mould when serious, so that mould risks exist. Therefore, we propose a hot roll for producing medical hydrophilic non-woven fabrics. Disclosure of utility model In view of the above, the utility model provides a hot roller for producing medical hydrophilic non-woven fabrics, which is used for solving the problem that the length of the hot roller in the prior art is larger than the width of the non-woven fabrics, and the temperature of the two sides of the non-woven fabrics is high easily caused during heating. The hot roller for producing the medical hydrophilic non-woven fabric comprises a hollow roller, wherein two ends of the roller are fixedly communicated with hollow rotating shafts respectively, sealing plates are arranged at two ends of the inside of the roller in a sliding sealing manner, and a hot oil heating area is formed in a space between the two sealing plates; the device also comprises a hot oil tank, wherein one side of the hot oil tank is communicated with a hot oil pump, an outlet of the hot oil pump is communicated with one end of one of the communicating pipes through a first oil pipe, and a communicating pipe on the other sealing partition plate is communicated with one side of the hot oil tank through a second oil pipe. Preferably, the limiting structure comprises a plurality of uniform baffles fixedly sleeved on the communicating pipe and a handle screw which is arranged on the rotating shaft in a threaded manner, wherein the lower end of the handle screw can be clamped between the two baffles so as to limit the position of the communicating pipe. Preferably, the surface sliding sleeve of the roller is provided with a high-temperature-resistant heat-insulating check ring, and the heat-insulating check ring is made of perfluororubber. Preferably, the heat insulation plate with the arc-shaped structure is arranged above the roller at intervals and is fixedly connected to the hot rolling mill through the connecting frame, and the rotating shaft is rotatably arranged on the hot rolling mill through the bearing. Preferably, at least two groups of heat insulation check rings are arranged, and the heat insulation check rings positioned outside the roller are aligned with the position of the sealing plate positioned inside the roller. Preferably, the sealing plate is made of high-temperature-resistant ceramic, and a sealing ring is fixedly sleeved on the circumference of the sealing plate and made of high-temperature-resistant perfluororubber. Preferably, the first oil pipe and the second oil pipe are respectively connected with the communicating pipe in a rotating way through a rotary joint. The implementation of the embodiment of the utility model has the following beneficial effects: The hot roller for producing the medical hydrophilic non-woven fabric is adopted; The hot oil heating area is formed in the space between the two sealing plates, and the length of the hot oil heating area is flexibly adjusted according to the width of the non-woven fabric during production, so that the heating area is basically consistent with the width of the non-woven fabric, and the problem that the local temperature of the side edge of the non-woven fabric is higher is avoided; Compared with the existing integrally-heated hot press roller, the application reduces the heating area according to the width of the non-woven fabric, avoids extra heat loss and saves more energy; the heat loss can be reduced from the outside of the roller through the heat insulation check ring and the heat insulation plate, and the heat insulation check ring can adjust the position according to the requirement
