Woven tape dyeing machine

Abstract

The mesh belt dyeing machine of the invention relates to the device field of mesh belt dyeing, which includes a dyeing device, a drier and a material-receiving device which are sequentially arranged. A differential drawing device is arranged between the drier and the material-receiving device. The differential drawing device includes a first differential group and a second differential group arranged subsequently and connected with the first differential group by the mesh belt. The rotating speed of a roller group of the second differential group is different from that of the roller group of the first differential group. The drier is provided with a plurality of drying boxes which adopt fuel gas to heat. The drying boxes are arranged horizontally. The drying box includes a drying box body, a gas furnace combustion chamber provided with a fan, and a heat box. The gas furnace combustion chamber is arranged outside the drying box body. The heating box is arranged at the lower end inside the drying box body and is communicated with the gas furnace combustion chamber. The upper part of the heating box is provided with a heat source zone. The inside of the drying box is provided with a plurality of driving rollers so as to drive the mesh belt. The mesh belt dyeing machine can carry out effective drawing compensation on the mesh belt with large tonnage and can fast dry the mesh belt after dyeing; besides, the mesh belt dyeing machine can reduce the cost and improve the manufacture efficiency.

Description

technical field [0001] The invention relates to the field of ribbon dyeing equipment, in particular to a ribbon dyeing machine for dyeing and drying wide ribbons. Background technique [0002] Ribbon dyeing machine is generally composed of dyeing tank, oven, transmission and conveying mechanism, among which the oven is the part that requires the most energy. In general dyeing machines, when the webbing passes through the oven, the webbing will shrink to varying degrees after being baked. However, the output mechanism of the traditional dyeing machine is limited by conditions, and cannot effectively compensate for the stretching of large-tonnage webbing, which makes it difficult to control the elongation rate during use within the range of international general standards, so the market positioning of the product is also affected. There is a certain limit, and correspondingly due to the increase in shrinkage, the output of products sold in units of length will also decrease a...

Problems solved by technology

However, the output mechanism of the traditional dyeing machine is limited by conditions, and cannot effectively compensate for the stretching of large-tonnage webbing, which makes it difficult to control the elongation rate during use within the range of international general standards, so the market positioning of the product is also affected. A certain limit is imposed, and correspondingly due to the increase in shrinkage, the output of products sold in units of length will be correspondingly reduced

[0003] On the other hand, most of the thermal energy in the oven of the dyeing machine is electric energy, which consumes a lot of energy.

With the increase in the degree of industrial electrification in recent years, the economy's dependence on electricity has reached an unprecedented height, resulting in a demand for electricity in short supply. For enterprises that use electricity as the main driving force, they often cannot meet their needs, and the cost of electricity has also increased significantly. increase; secondly, the drying device of the traditional dyeing machine is narrow-width continuous electric heating drying, and its main oven is heated by electric heating wires. Since the heating pipe is directly installed around the main box, the heat radiates from the main box to the middle, resulting in The thermal radiation energy received by the middle part is much lower than that received by the surroundings of the main box, and the heating is severely uneven, resulting in color difference in the same belt, and it is easy to cause one belt to change color due to overheating, and the other part to discolor due to insufficient heating; Because the traditional dyeing machine uses a drying box, it is necessary to ensure that the webbing can be dried. The time that the webbing can stay in the box at a certain temperature is certain, which limits the output per unit time, so the production efficiency is low.
