Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a guide roller for high-temperature resistant quick-drying textiles. Background Art

[0002] Textile machinery is a kind of equipment used to process raw materials such as thread, silk, and hemp into silk thread and then weave it into cloth. As the core component of textile machinery, the cloth guide roller is mainly composed of the shaft head and the roller body. The roller body is mostly made of chrome-plated seamless steel pipe or stainless steel pipe to ensure its durability and smooth surface. During the weaving and dyeing process, the cloth guide roller guides the fabric to move along the predetermined path through the friction between its surface and the fabric. At the same time, the tension and direction of the fabric can be controlled by adjusting the speed and position to ensure the flatness and stability of the fabric.

[0003] Traditional cloth guide rollers are mostly solid structures. The heat generated when running at high speed or using for a long time is difficult to dissipate quickly, which causes volume heating of the roller, affecting its mechanical properties and stability. At the same time, the high temperature of the cloth guide roller is also easy to cause uneven heating of the contacted fabric, causing it to deform, wrinkle or discolor, thus affecting the appearance quality and performance of the finished product. In addition, in the textile printing and dyeing process, a large amount of water vapor is generated during the heating and drying process of the fabric. When the fabric is transmitted through the cloth guide roller, because the surface of the traditional solid cloth guide roller is tightly attached to the fabric, it is difficult for the water vapor to escape from the gap between the roller body and the fabric, causing the fabric to harden during the transmission process, thus affecting the softness and comfort of the finished product.

[0031] Please refer to Figure 1-6 A high-temperature resistant quick-drying textile guide roller comprises a shaft head 1, an end cover 2 and a roller body 3, wherein a barrel-shaped air duct 4 is coaxially provided in the roller body 3, wherein there are two end covers 2, which respectively cover the left and right ends of the barrel-shaped air duct 4, wherein a first air supply device is provided between one of the end covers 2 and the barrel-shaped air duct 4, and a flow guide structure which is connected to the roller body 3 for heat conduction and cooperates with the first air supply device for heat dissipation is provided in the barrel-shaped air duct 4;

[0032] The guide structure includes a support frame 5 parallel to the radial section of the barrel-shaped air duct 4, and the support frame 5 is provided with a plurality of equidistantly arranged side by side along the axial direction of the barrel-shaped air duct 4.

[0033] The support frame 5 includes an integrally formed central portion 6 and a heat-conducting branch pipe 7, the heat-conducting branch pipe 7 is preferably a copper pipe, the central portion 6 is arranged on the central axis of the barrel-shaped air duct, the heat-conducting branch pipe 7 is radially distributed outward with the central portion 6 as the center, and the other end of the heat-conducting branch pipe 7 is fixedly connected to the peripheral wall of the barrel-shaped air duct 4 outward;

[0034] A plurality of heat-bearing ring bodies 8 with diameters decreasing from the outside to the inside are coaxially arranged in the barrel-shaped air duct 4. The heat-conducting branch pipe 7 of each supporting frame 5 is fixedly connected to the heat-bearing ring body 8 to introduce the heat of the roller surface into the heat-bearing ring body 8. A heat exchange area of ​​the barrel-shaped air duct 4 is formed between the inner and outer ring surfaces of adjacent heat-bearing ring bodies 8. The air outlet end of the first air supply device is arranged toward the heat exchange area.

[0035] The end cover 2 includes an outer side surface fixedly connected to the shaft head 1, and an inner side surface fixedly connected to the roller body 3, a connecting portion 15 extending into the barrel-shaped air duct 4 is fixedly provided on the inner side surface, a plurality of air inlets and outlets 9 leading to the connecting portion 15 are evenly distributed along the circumferential direction on the end cover 2, and a filter plate 10 for blocking fabric debris is provided on each air inlet and outlet 9.

To ensure a good airflow effect, the diameter of the wind wheel of the first fan 11 is not less than the diameter of the outermost heating ring 8. Figure 3-4 As shown, the first fan 11 is installed on the left side of the barrel-shaped air duct 4, and when started, it transports external air into the barrel-shaped air duct 4 from the left side.

[0037] A second air supply device is provided between the other end cover 2 and the barrel-shaped air duct 4, and the air inlet end of the second air supply device can be oriented toward or away from the first air supply device. Specifically, the second air supply device is a second fan 12 fixedly arranged in the connecting portion 15 of the other end cover 2, and the fan is driven by a bidirectional motor. Similarly, the diameter of the wind wheel of the second fan 12 is not less than the diameter of the outermost layer of the heat ring 8. Figure 3-4 As shown, the second fan 12 is installed on the right side of the barrel-shaped air duct 4, and its blade direction is the same as that of the first fan 11.

[0041] Working principle: The utility model is a guide roller for high temperature resistant quick-drying textile, including two working modes: heat dissipation and quick drying:

[0042] [Working mode 1] (Cooling mode)

[0043] like Figure 3 As shown, the first fan 11 and the second fan 12 are started, and the second fan 12 rotates in the same direction as the first fan 11. At this time, external air enters the barrel-shaped air duct 4 from the air inlet and outlet 9 of the left end cover 2, passes through the heat exchange area for heat exchange, and is discharged from the air inlet and outlet 9 of the right end cover 2, taking out the heat from the roller surface; during the air flow, part of the gas escapes to the roller surface through the air outlet, and an air film can be formed between the roller surface and the fabric, effectively preventing the fabric from sticking.

[0044] [Working mode 2] (Quick drying mode)

[0045] like Figure 4 As shown, the first fan 11 and the second fan 12 are started, and the second fan 12 rotates in the opposite direction to the first fan 11. At this time, external air enters the barrel-shaped air duct 4 from the air inlet and outlet 9 of the left and right end covers 2 respectively. After convection occurs in the middle of the barrel-shaped air duct 4, most of the air is discharged from the air outlet 13 on the roller surface, which directly enhances the air outlet intensity of the air outlet 13 and further improves the drying effect of the fabric on the roller surface.

[0046] The utility model provides a barrel-shaped air duct 4 in the guide roller and a flow guide structure in the barrel-shaped air duct 4, so that the heat generated by the friction of the roller surface is taken away from the roller body 3 through the air flow introduced by the air supply mechanism, effectively preventing the roller body 3 from accumulating heat at high temperature, increasing its stability in use, and ensuring the appearance quality and use performance of the fabric; by providing vents and air outlets, the air flow in the barrel-shaped air duct 4 can flow outward to the roller surface, effectively preventing the fabric from sticking, and at the same time accelerating the evaporation and volatilization of water vapor, thereby preventing the fabric from becoming hardened and hardened, and effectively improving the softness and comfort of the finished product.

[0047] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
