Color developing and fixing device for wall cloth printing and developing machine

Abstract

The invention relates to the technical field of thermal dye sublimation wall cloth printing, and discloses a color developing and fixing device for a wall cloth printing and developing machine. The color developing and fixing device includes a color developing mechanism and a color fixing platform arranged above the color developing mechanism. The color developing mechanism includes a heating drum, a blanket belt and a driving roll group. The driving roll group includes a first driving roll located above the right side of the heating drum, a second driving roll arranged on the left side of theheating drum and a third driving roll arranged below the right side of the heating drum. One side of the blanket belt is wound into the left side of the heating drum from the lower end of the heatingdrum and is wound out of the upper end of the heating drum. The rotation direction of the heating drum is clockwise. The color fixing platform includes a first rotary roll, a second rotary roll, anda conveyor belt of which the two ends are respectively wound on the first rotary roll and the second rotary roll. The device can facilitate the full color developing and fixing of the wall cloth, better guarantee the smoothness of the wall cloth during heating, make the wall cloth heated uniformly, and help save the overall floor area of the equipment.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation wall cloth printing, in particular to a color developing and fixing device for a wall cloth printing color developing machine. Background technique [0002] As a popular decoration material nowadays, wall coverings are widely used in meeting rooms, hotel lobbies, mid-to-high-end residences and other places. There are two ways to color wall coverings on the market. One is knitted jacquard. Such wall coverings have Concave-convex three-dimensional, exquisite, but the disadvantage is that knitted jacquard is restricted by modern technology and its own characteristics, and cannot make bright colors and complex patterns. Another way is to use digital printing, which is widely used in the clothing industry. , Such as printing various bright patterns on T-shirts, it is less used on wide-width wall coverings. [0003] At present, the production process of the widely used digital printing of w...

AI Technical Summary

Problems solved by technology

Although the temperature treatment of the wall covering in multiple processes is relatively comprehensive, which helps the wall covering to develop and fix the color to a certain extent, but the entire color developing process is exposed to the air, and it is heated by the heat conduction of the air, which is prone to uneven heating and the product. The pattern is not bright. In addition, the flatness of the wall covering in the whole process of heating and color rendering cannot be guaranteed only by the pressure plate set in the fixed area. There are cases of wall covering deformation during use, and the heat dissipation and drying area is also limited by its space length. In order to achieve good heat dissipation and drying, and to achieve excellent color fixation, it is necessary to slow down the speed of unwinding and rewinding the cloth, or increase the wind power of the fan, which is not conducive to high efficiency and energy saving

[0005] Another example is "a kind of constant temperature thermal sublimation color development machine" disclosed in the patent literature with the publication number CN106739551A, which includes a frame, an open-width cloth releasing roller, a cloth receiving and conveying roller, an oil-electric heating roller, a geared motor, a bracket, a rotary joint, Oil tank, electric heater, electric brush device, smoke collecting hood, smoke exhaust pipe, fan, front cover and rear cover; the fabric can be heated evenly by using heat conduction oil to improve the color rendering and color fixing performance, but it needs Manually spread the cloth through the open-width release roller and wrap it around the heated oil-electric heating roller, and pass it out through the cloth receiving and conveying roller. There are certain safety hazards, and the cloth is not heated on both sides. After being heated on the roller for one week, the wound cloth is directly passed through the cloth conveying roller, which cannot achieve ideal drying, cooling and color fixing effects for thicker wall coverings
