Multi-independent-temperature-zone mesh stove and its control method

Abstract

The invention relates to a type of belt-reticulation furnace with multiple independent warm areas. It comprises furnace body, transporting reticulation belt set in the furnace body, heating element, wind power system and control system controlling process parameter such as temperature of the furnace and wind power etc. There are several independent heating warm areas along portrait of the transporting reticulation belt and independent heating elements and wind systems in each heating warm area. The control system includes controller controlling heating power in each independent heating warm area and controller controlling wind power in each independent heating warm area. The power line connections of each independent heating element and wind power system connect respectively with control ports of heating power and wind power in corresponding area. The invention can reduce experience and randomicity of technologic setting and adjusting. It controls temperature sectionally more accurately and more effectively. Also it can improve the production efficiency of printing and dyeing and dying and the quality of product.

Description

【Technical field】 [0001] The invention relates to a textile printing and dyeing drying furnace, more specifically, the invention relates to a mesh belt type textile printing and dyeing drying furnace and a control method thereof. 【Background technique】 [0002] In the textile printing and dyeing industry, the products printed on substrates with various dyes need post-drying to fix the printing dyes. The main purpose of drying is to remove the solvent in the printing ink. The mesh belt drying furnace is widely used in the printing industry. . [0003] With the improvement of people's living standards, aesthetic tastes tend to be diversified, and people have more and more requirements for patterns and colors on textiles. Small batches of multiple colors have become the development direction of the marketing of the textile printing and dyeing industry. As a result, in the printing and drying process of textile products, the same oven needs to frequently replace the types of p...

Problems solved by technology

[0004] The existing drying furnace has taken into account the special needs of each textile printing process, appropriately increased the overall length of the drying furnace and has multiple heating temperature zones in the drying furnace, the heating of each temperature zone The power is independently regulated, and this improvement can basically meet the special process requirements for each textile printing variety. However, due to the interaction of various process parameters, especially the cross temperature between the temperature zones caused by the wind cycle, the The temperature control of the segmental heating of the existing oven cannot be accurately realized, and the effect is also compromised. What is more serious is that the independent temperature control of the segmental heating temperature zone of the oven cannot be accurately realized, resulting in the adjustment of the current drying process parameters. Difficulty and inefficiency: every time a printing product is replaced, the operator needs to reset it based on previous records and experience. The adjustment effect mainly depends on the operator's working experience in the printing process and the familiarity with the specific furnace structure and history. degree, with considerable subjectivity and randomness, it is difficult to guarantee the stability and reproducibility of process adjustment, and the adjustment work is complicated, which affects production efficiency and product quality
