Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer machines, in particular to a heating roller of a heat transfer machine with uniform heat transfer. Background Art

[0002] Transfer printing is a new type of textile transfer printing method, which can achieve transfer printing on natural fabrics. However, the roller heating effect of the transfer device in the prior art is poor, the heating is uneven, and the temperature cannot be controlled. Reactive dyes often have limited solubility, and the solubility of the dyes is even worse when the temperature is lower in winter. Therefore, the transfer rate of cold transfer printing is low and the transfer effect is poor. Utility Model Content

[0003] The utility model aims to solve the problems existing in the background technology and proposes a heating roller for a heat transfer machine with uniform heat transfer.

[0004] The technical solution of the utility model is as follows: a heating roller of a thermal transfer machine with uniform heat transfer, comprising a cylinder body, a heating structure installed in the cylinder body, the heating structure comprising a heating cylinder, a heating cavity inside the heating cylinder, a plurality of isolation plates equidistantly distributed outside the heating cylinder, a heat conduction cavity is formed between adjacent isolation plates, an oil outlet and an oil return port opened at both ends of the heating cylinder are arranged in the heat conduction cavity, the heating structure also comprises a cover plate, a heating rod is installed on the cover plate, the cover plate is installed outside the cylinder body, and the heating rod is located in the heating cavity.

[0005] Preferably, one end of the heating cylinder is fixedly mounted in the cylinder, and the isolation plate is not in contact with the inner wall of the cylinder.

[0006] Preferably, the heat conduction cavity is surrounded by two left and right isolation plates and the outer wall of the heating cylinder.

[0007] Preferably, the heating tube includes an outer tube body and an inner tube body, and the heating tube also includes a graphite layer arranged between the outer tube body and the inner tube body. The temperature uniformity of the heating tube using the graphite interlayer is greatly improved, so the heating tube can also directly transfer heat, thereby improving the heat transfer efficiency so that it does not rely solely on the flow of heat transfer oil to transfer heat.

[0008] Compared with the existing technology, the beneficial effect of the utility model is as follows: the present scheme is divided into a plurality of heat-conducting cavities by setting a heating structure and installing an isolation plate, so that the heated part of the cylinder is also divided, and the heat-conducting oil will flow evenly through each heat-conducting cavity, so that the heated part of the cylinder in each heat-conducting cavity will be evenly heated, and because the cylinder is rotated at a high speed during use, the heat-conducting oil will flow in the heat-conducting cavity, then the heat-conducting oil will flow into the heat-conducting cavity from the oil outlet for heating, and then will be discharged into the heating cavity from the oil return port for reheating, thus forming a circulating heating oil circuit, thereby ensuring the heating effect.

The heat-conducting oil in the heat chamber 26 is in direct contact with the cylinder 1 to heat the cylinder 1, thereby achieving the heating of the cylinder 1. The installation of the isolation plate 24 divides it into a plurality of heat-conducting chambers 26, so that the heated part of the cylinder 1 is also divided, and the heat-conducting oil will flow evenly through each heat-conducting chamber 26, so that the heated part of the cylinder 1 in each heat-conducting chamber 26 will be evenly heated. Moreover, because the cylinder 1 is rotated at a high speed during use, the heat-conducting oil will flow in the heat-conducting chamber 26, so the heat-conducting oil will flow from the oil outlet 27 into the heat-conducting chamber 26 for heating, and then it will be discharged into the heating chamber 25 from the oil return port 28 for reheating, thus forming a circulating heating oil circuit, thereby ensuring the heating effect.
