Description

Technical Field

[0001] This utility model belongs to the field of filter paper folding technology, and in particular relates to a filter paper tightening and conveying device for a filter paper folding machine. Background Technology

[0002] Folding the filter paper is a key step in the filter production process. The flat filter paper is folded into a shape with multiple pleats by a folding machine. After folding, the filtration area of ​​the common cylindrical filter paper can be increased several times compared to the original flat filter paper. This is like folding a flat sheet of paper into an accordion shape, which greatly increases the area available for filtration in a limited space, thus enabling more effective interception of impurities.

[0003] Currently, most filter paper is folded into pleats using a folding machine. During the folding process, the filter paper needs to be conveyed by a conveying device. However, the filter paper may become loose or wrinkled during conveying, which could lead to substandard folded filter paper. Therefore, a filter paper tensioning and conveying device is needed for filter paper folding machines. This device can tension the filter paper through a tensioning structure to prevent it from becoming loose or wrinkled during conveying, thus ensuring the stability of the filter paper conveying process.

A mounting plate is fixedly connected to the inner cavity of the fixed frame. A cylinder is fixedly mounted on the bottom of the mounting plate by threads. The output end of the cylinder passes through the mounting plate and is fixedly connected to the bottom of the slide frame.

[0024] Working principle: When using this utility model, the user moves the filter paper through the top of the two conveying rollers 14 and then through the bottom of the tensioning roller 5. The cylinder 13 is then activated, causing the slide 3 to move. Through the limiting of the slide groove 10, the slide 3 drives the tensioning roller 5 to slide downward through the slide 4. At this time, the tensioning roller 5 will pull and tighten the filter paper, preventing the filter paper from becoming loose or wrinkled during conveying, thus ensuring the stability of the filter paper conveying. When the tension of the slide 4 on the filter paper is too great, the spring 8 will be compressed and contracted to prevent the tension of the tensioning roller 5 from causing the filter paper to break due to excessive tension.

[0025] In summary, this filter paper tensioning and conveying device for a filter folding machine achieves the goal of tensioning and conveying the filter paper by passing it over the top of the two conveying rollers 14 and then over the bottom of the tensioning roller 5. Activating the cylinder 13 causes the slide 3 to move. Through the limiting action of the slide groove 10, the slide 3 drives the tensioning roller 5 downwards via the slide 4. This tensioning structure ensures the filter paper is tensioned and conveyed, preventing it from becoming loose or wrinkled during transport and guaranteeing the stability of the filter paper conveying.
