Abstract
Description
Technical Field
[0001] The utility model relates to an ironing mechanism, in particular to an ironing roller and an ironing mechanism for processing lining fabrics. Background Art
[0002] During the production process, the lining fabric needs to go through the ironing and shaping process. The ironing equipment used in the production process is generally composed of a machine body, a guide roller group for guiding the fabric, and an ironing roller group. The ironing roller in the ironing roller group has the effect of heating and flattening. When the cloth passes between the two ironing rollers, it will be heated and rolled. After the cloth cools down, it will be shaped into a flat state. The heat source of the ironing roller is generally one of steam, hot water and electric heating body, and the heat is transferred to the ironing roller through heat conduction or heat radiation. The cloth will continuously consume heat during the ironing process. The faster the cloth is conveyed, the faster the heat is taken away. However, the ironing roller can only maintain the working temperature when the heat consumption rate is less than or equal to the heat transfer efficiency. Therefore, the ironing efficiency of the current ironing equipment is restricted by the efficiency of heat transfer, especially the ironing mechanism with steam as the heat source. Because the specific heat capacity of steam itself is small, and heat can only be transferred by heat conduction, the overall heat transfer efficiency is low, and the ironing rate is restricted. Summary of the invention
[0003] The utility model provides an ironing roller for processing lining fabrics, which solves the problem of low ironing speed of an ironing mechanism using steam as a heat source in the prior art.
[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: an ironing roller for lining fabric processing, characterized in that: it includes a fixed shaft and a sleeve coaxially sleeved on the outside of the fixed shaft, an annular cavity is formed between the two, annular mounting seats are respectively provided at both ends of the fixed shaft, the sleeve coaxially rotates relative to the annular mounting seat, a plurality of mutually spaced annular inner baffles are provided on the outer wall of the fixed shaft, the annular inner baffles are spaced apart from the inner wall of the sleeve, a plurality of mutually spaced annular outer baffles are provided on the inner wall of the sleeve, the annular outer baffles are spaced apart from the outer wall of the fixed shaft, the annular outer baffles and the annular inner baffles are interlaced with each other, an air inlet cavity and an air outlet cavity are respectively provided at both ends of the fixed shaft, and both are connected to the annular cavity.
[0005] Hot steam is input from the air inlet cavity of the utility model and then flows into the annular cavity. Since the annular cavity is blocked by the annular outer baffle and the annular inner baffle, the hot steam can only flow in a continuous S-shaped flow path. In annular cavities of the same length, such a flow pattern can greatly extend the residence time of the hot steam in the annular cavity. At the same time, the annular outer baffle can increase the contact area between the sleeve and the hot steam, thereby improving the heat transfer efficiency of the utility model, which is beneficial to improving the upper limit of the ironing efficiency of the utility model.
[0006] Furthermore, the sleeve includes a first shell, a second shell and two positioning rings, the positioning rings are rotatably matched with the annular mounting seat, the outer wall of the positioning ring is provided with a concave annular groove, and the first shell and the second shell are fixed in the annular groove. The sleeve is divided into two, and the annular outer partition is also divided into two, which is designed for practical installation convenience.
[0007] Furthermore, the outer sides of the first shell and the second shell are covered with heat-resistant annular silicone sleeves, which are made of elastic material, so they are not easy to crush the cloth, and can also increase friction to prevent the cloth from slipping.
[0008] Furthermore, a transmission wheel is coaxially fixed on one of the positioning rings, and the transmission wheel is any one of a gear, a sprocket and a pulley. After the transmission wheel is connected to the power end, it has a rotation effect.
[0009] The utility model also provides an ironing mechanism, including an ironing machine body and a plurality of ironing rollers arranged thereon, characterized in that the ironing rollers are the above-mentioned ironing rollers for processing lining fabrics. Since the above-mentioned ironing rollers for processing lining fabrics have the above-mentioned technical effects, the ironing mechanism having the ironing rollers also has the same technical effects.
[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The heat source of the utility model is hot steam, and the annular cavity is blocked by the annular outer partition and the annular inner partition. The hot steam can only flow in a continuous S-shaped flow path. In the annular cavity of the same length, such a flow mode can greatly prolong the residence time of the hot steam in the annular cavity. At the same time, the annular outer partition can increase the contact area between the sleeve and the hot steam, thereby improving the heat transfer efficiency of the utility model, which is beneficial to improving the upper limit of the ironing efficiency of the utility model.
