Wallpaper foaming heating box capable of achieving even air blowing

Abstract

The invention relates to a wallpaper foaming heating box capable of achieving even air blowing. The wallpaper foaming heating box comprises a shell, a motor, a dual-outlet exhaust fan, a heating chamber, an air blowing box and a plurality of draught fans. The motor is fixedly arranged at the upper end of the shell. An output shaft of the motor stretches downwards into the shell and fixedly connected with the dual-outlet exhaust fan. The dual-outlet exhaust fan, the heating chamber and the air blowing box are located inside the shell. The heating chamber is located at the lower end of the dual-outlet exhaust fan and communicated with the dual-outlet exhaust fan. Two air outlets of the dual-outlet exhaust fan are communicated with the air blowing box through air pipes. The draught fans are located at the positions, communicated with the air pipes, inside the air blowing box. A channel for heating passing wallpaper is arranged inside the air blowing box and transversely penetrates the air blowing box. A plurality of nozzles are arranged on the inner wall, close to the channel, of the air blowing box. The wallpaper foaming heating box can achieve even air blowing, the temperature difference is small, and the product quality is stably controlled.

Description

Technical field [0001] The invention relates to the technical field of wallpaper foaming, in particular to a wallpaper foaming heating box with uniform blowing. Background technique [0002] At present, foamed embossed wallpaper is a major category of wallpaper. It is used in a huge amount in the market. As the most important foaming link in embossing production, it ensures stable and efficient heat source, guarantees the embossing quality of wallpaper and reduces wallpaper. The chromatic aberration on the web is a necessary condition to increase productivity, increase yield, and increase efficiency. [0003] In the production of embossed wallpaper, the heating effect of the heating box is the most important part of the production process, and the stable, safe, efficient and energy-saving heating equipment is a difficult problem in the equipment manufacturing, and we also serve as our equipment manufacturer. Product users must face problems to improve efficiency and create value. ...

AI Technical Summary

Problems solved by technology

Common wallpaper heating boxes are mostly heated by oil. The disadvantage of oil heating is that the temperature of the box rises slowly, and the preparation time for equipment startup is long; the thermal inertia of the oil heating box is large during the production process, the temperature adjustment response is slow, and the quality control is not effective; The internal blowing box of conventional equipment is composed of an independent box, which is likely to cause uneven air flow at both ends of the box, and the temperature difference of the entire box is too large, resulting in wallpaper foaming and color difference, resulting in defective products or even waste products; conventional oil heating box The thermal efficiency is low, it is difficult to meet the heating demand of the high-speed wallpaper production line
