[0040] like Figure 4 and Figure 5 As shown, a layer-changing shell 6c is fixedly provided on the end face of the box 1c. The layer-changing shell 6c is a heat-insulating structure.

An automatic deviation correction roller 2d is provided between the unwinding device 1d and the impregnation and dehydration treatment device 3d and between the drying and curing treatment device 4d and the winding device 5d.

[0041] The working principle of the present invention is as follows: the rolled base cloth or filter material is rotated and installed on the unwinding device, and the base cloth or filter material is successively passed through the unwinding device, the impregnation and dehydration device, and the drying and curing device, and then wound on the winding roller set on the winding device; the winding roller rotates to make the base cloth or filter material move in the production line. After the base cloth or filter material is impregnated in the impregnation tank body, it is dehydrated by the dehydration device, and then enters the drying and curing device. The base cloth or filter material is dried in the heat insulation cavity at the upper part of the box body, and cured in the heat insulation cavity at the lower part of the box body. The temperature of each layer of the heat insulation cavity is adjusted by a circulating hot air blower to control the drying and curing process of the base cloth or filter material, and the processed base cloth or filter material is rolled on the winding device.

[0042] Among them, combined Figure 2 As shown, the first basic winding method is shown in C, the base fabric enters the tank body and passes through the lower part of the first impregnation roller, the upper part of the second impregnation roller and the lower part of the third impregnation roller in turn, and then passes out of the tank body; this winding method is suitable for base fabrics with thinner thickness, which pass through the tank body for a short time and are subjected to small tension. The second basic winding method is shown in A, the base fabric enters the tank body and passes through the right side of the first impregnation roller, the bottom of the fourth impregnation roller, the upper part of the second impregnation roller, the bottom of the fifth impregnation roller and the left side of the third impregnation roller in turn, and then passes out of the tank body; this winding method is suitable for base fabrics with thicker thickness, which pass through the tank body for a long time and are subjected to large tension. The third basic winding method is shown in B, the base fabric enters the tank body and passes through the left side of the first impregnation roller, the bottom of the fourth impregnation roller, the bottom of the fifth impregnation roller and the right side of the third impregnation roller in turn, and then passes out of the tank body; this winding method is suitable for base fabrics with moderate thickness, which pass through the tank body for a moderate time and are subjected to moderate tension. In addition, other winding methods will not be described one by one. The general principle is to select all or part of the impregnation rollers for winding according to the thickness of the base cloth so that the base cloth is subjected to appropriate tension and impregnation time. Those skilled in the art should have the ability to use the above-mentioned winding method, so it will not be explained in detail here. After the base cloth is impregnated in the impregnation tank, it enters the extrusion dehydration device, and then passes through the wind knife dehydration device and the negative pressure dehydration device. After the base cloth or filter material is extruded and dehydrated by the extrusion dehydration device, it passes through the wind knife and the negative pressure suction port for wind dehydration; extrusion dehydration can separate most of the liquid in the filter material, and then when passing through the wind knife and the negative pressure suction port, it can separate the remaining small amount of liquid in the filter material. Of course, when the thickness of the base cloth or filter material is small, the extrusion dehydration device does not work, and it is dehydrated by one or both of the wind knife dehydration device and the negative pressure dehydration device.

[0043] In addition, the base fabric to be dried and cured enters the box from the feed port at the top of the box and is supported and transported by the conveyor belt. The base fabric enters the next insulation cavity at the position where the adjacent insulation cavities are connected. The base fabric is transported in an S shape in the multi-layer insulation cavity under the action of the multi-layer conveyor belt. The conveyor belt is a breathable structure. The hot air discharge port discharges the hot air generated by the circulating hot air blower to the bottom of the conveyor belt. The hot air rises through the conveyor belt and evaporates the moisture in the base fabric. The hot air recovery port recovers the hot air containing moisture above the conveyor belt into the circulating hot air blower. The circulating hot air blower dehumidifies and heats the gas and discharges it back into the box, thereby achieving the drying and curing of the base fabric and the hot air circulation in the box. Due to the multi-layer setting of the conveyor belt and the insulation layer, the state of the base fabric to be processed entering each insulation cavity in turn is changing. According to the insulation effect and temperature control of each insulation cavity, the purpose of drying and curing the base fabric can be achieved.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
