[0002] The filter base fabric belongs to a kind of base fabric and is widely used in manufacturing dust removal filter bags. Before the filter bags are processed, the filter base fabric needs to be coated with PTFE. The filter cloth is soaked in PTFE emulsion for coating treatment, and finally the filter bags are made. When feeding and processing the base fabric, a cloth feeding device is often needed. However, most of the existing cloth feeding devices only play the role of feeding, and thus do not have the functions of tensioning the base fabric during the conveying process and cleaning the surface impurities. The cloth feeding device with such a structure is likely to cause the base fabric to wrinkle and adhere to impurities on the surface of the base fabric during the production process of the base fabric, reducing the subsequent processing quality. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a filter base fabric production device, which is used to solve the technical problems that the cloth feeding device in the prior art in the background art has a single function, resulting in wrinkles and poor quality of the produced base fabric.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A filter base fabric production device includes a U-shaped installation frame. Four conveying rollers distributed in a rectangle are rotatably installed in the installation frame. Two cleaning rollers symmetrically arranged left and right are rotatably installed in the installation frame. A protective cover is fixed in the installation frame. The protective cover covers the two cleaning rollers. Through openings are formed at both the upper and lower ends of the protective cover. The protective cover is located between the two leftmost conveying rollers. Two tensioning rollers symmetrically arranged up and down are slidably arranged in the installation frame. The tensioning rollers are located between the left and right conveying rollers. An adjusting mechanism is arranged on the installation frame. The adjusting mechanism includes two tensioning frames that can move towards or away from each other simultaneously by the same distance. The two tensioning frames are symmetrically arranged up and down. The two tensioning rollers are respectively rotatably installed on the corresponding tensioning frames.

[0006] Working Principle:

[0007] The filter media base fabric successively passes through a conveying roller located below the right end, a tensioning roller located at the lower end, a conveying roller located below the left end, a material passing opening located at the lower end, between two cleaning rollers, a material passing opening located at the upper end, a conveying roller located above the seat end, a tensioning roller located at the upper end, and a conveying roller located above the right end. By adjusting the distance between the two tensioning frames, the two tensioning frames drive the two tensioning rollers to move synchronously towards or away from each other by the same distance, realizing the tension adjustment of the filter media base fabric. When the filter media base fabric passes between the two cleaning rollers, the two cleaning rollers perform surface cleaning treatment on both end faces of the filter media base fabric.
