[0002] With the improvement of corporate environmental awareness and the country's high attention to environmental protection, the number of large-scale bag dust collectors in use is increasing. After searching, it was found that the announcement number is CN219539713U, and the name is a dust collector bag with high sealing performance. This application can facilitate the staff to install the fastening ring through the setting of the limit mechanism. The installation is completed by pushing the fastening ring downward through the limit block to the limit of the limit rod, and then the fastening ring is pushed downward and pulled once to complete the disassembly, which is convenient for the staff to operate and improves the convenience of use.

[0003] This application is for high-sealing dust collector bags with high sealing performance. However, there is currently no testing equipment for the sealing performance of dust collector bags on the market, which makes it impossible to verify their high sealing performance. Manufacturers can only rely on experience or directly install them into the equipment for verification. Bag-type dust collector equipment is large in size, and the installation and removal of dust bags requires downtime, which results in a large workload and serious economic losses. Therefore, there is an urgent need for a dust collector bag sealing performance testing device to fill the market gap and facilitate manufacturers to enter the factory for testing and use.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
