High-efficiency circular blowing device for baking oven of tenter setting machine

Abstract

The invention relates to a high-efficiency circular blowing device for a baking oven of a tenter setting machine. The high-efficiency circular blowing device is characterized in that a hot air intelligent convection circular adjusting structure is introduced; a main temperature sensor (15) and a secondary temperature sensor (16) which are respectively arranged at an air outlet of an air outlet pipeline (2) and a large-aperture port in an air return cover (3) are used for respectively acquiring temperature detection results at corresponding positions in real time; by combining with a main filter circuit (18) and a secondary filter circuit (19) which are specifically designed, temperature detection results of two positions are mutually compared; based on a comparison result, the distance between the air outlet of the air outlet pipeline (2) and the large-aperture port of the air return cover (3) is judged to be reasonable or not; based on a judgment result, a first electric telescopic rod (14) and a second electric telescopic rod (8) are intelligently controlled; movement of the large-aperture port in the air return cover (3) is controlled by an air return pipeline (4), and the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to a high-efficiency circulation blowing device in an oven of a stenter setting machine, belonging to the technical field of stenter setting machines. Background technique [0002] Fabric printing, also known as fabric printing, is the process of using dyes or paints to form patterns on fabrics. Printing is partial dyeing and requires a certain degree of color fastness. Currently commonly used printing techniques mainly include mechanical printing and manual printing. Mechanical printing is completed by a printing machine at one time, and the printing machine is a single machine. The disadvantage of machine printing is that the printed graphics are relatively rough, the colors are not bright enough, the layering is poor, and the number of colors is limited. Hand printing is the name of a printing process, and it does not mean that the printing is completely done by hand. Manual printing is a concept relative to machine printing....

AI Technical Summary

Problems solved by technology

In the stenter setting machine, an oven is used to steam the weaving fabric, and with the rapid development of production technology, the stenter setting machine is constantly improving and innovating. In practical applications, the stenter setting machine oven has many internal settings. A circular air spray frame, under the blowing action of the circulating fan, the air is continuously sprayed on the fabric from the pores on the circular air spray frame. However, there are some shortcomings in the structure of this circular air spray rack, that is, the distance between the hot air outlet hole and the moisture exhaust hole is relatively small, and convection is easy to form between the two, which will affect the air flow for the air outlet. The drying effect of the weaving, as well as the circular air spray rack continuously uses normal temperature air as the input source, so in order to continuously produce hot air at the preset temperature, it is necessary to continuously heat the normal temperature air to the hot air at the preset temperature, and the temperature drop Larger, this puts forward higher requirements on the power of the heating device, therefore, there are still some deficiencies in the existing stenter setting machine oven
