Description

Technical Field

[0001] The utility model relates to the technical field of air filter production, in particular to a filter multi-layer gluing device for air filter production. Background Art

[0002] An air filter is a device used to filter particles and pollutants in the air. During the production process of air filters, multiple layers of filter materials need to be coated with glue and compacted so that they are tightly glued together, thereby ensuring the stability and filtering effect of the filter.

[0003] The existing multi-layer filter screen gluing device is mainly composed of a feeding system, a glue coating system and a gluing and compacting system. When gluing, the multi-layer filter screen material is first fed into the glue coating system area through the feeding system according to a predetermined order and speed, and then the hot melt adhesive is evenly coated between the filter screen materials. When the glued multi-layer filter screen material is conveyed to the bottom of the gluing and compacting system, the multi-layer filter screen material is compacted by the action of the pressing roller so that it is tightly bonded together, thereby realizing the gluing operation.

[0004] In the existing multi-layer filter gluing device, each filter needs to be glued separately during gluing, which may easily lead to uneven distribution of glue on each filter, thereby affecting the overall filtering performance or stability of the filter after gluing. Before gluing, the filter surface is not cleaned, and the dust on the filter surface will hinder the effective contact and bonding between the glue and the filter surface, resulting in a decrease in gluing quality, and problems such as loose gluing, bubbling, and cracks may occur, thereby affecting the gluing effect. Therefore, in view of the above problems, a multi-layer filter gluing device for air filter production is proposed. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a filter screen multi-layer gluing device for producing air filter screens.

Before applying glue, a cleaning mechanism is set up, and the first scraper is always in contact with the surface of the first filter screen through the cooperation of the first spring and the first scraper. When the filter screen passes from under the first scraper, the first scraper can scrape and clean the dust attached to the surface of the first filter screen. The second scraper is always in contact with the surface of the second filter screen through the cooperation of the second spring and the second scraper. When the filter screen passes from over the second scraper, the second scraper can scrape and clean the dust attached to the surface of the second filter screen. The dust and oil on the surface of the filter screen can be effectively removed through the cleaning process, ensuring full contact and bonding between the glue and the surface of the filter screen, thereby improving the gluing quality, ensuring that the various parts of the filter screen are firmly combined, and not prone to bubbling, cracks and other problems, thereby improving the gluing effect.

Through line coating, it is easy to control the amount and distribution of glue, so that the glue is evenly distributed on the glue coating roller, so that the two filter screens can be coated with glue at the same time. Compared with the single gluing operation, it can ensure that the glue distribution on the two filter screens is more even, which helps to improve the stability and filtering performance after gluing.
