The gripper moves toward the thrust plate and grabs the filter frames one by one, and pulls the filter frames toward the clamping plate.

After the pushing plate 711 is pulled apart, the pushing mechanism 6 pushes the pushing plate 711 on the rotating ring 71 to rotate in sequence along the length direction of the beam 11. The pushing plate 711 rotates, driving the rotating ring 71 to rotate. The rotating ring 71 drives the winding ring 72 to rotate. The winding ring 72 winds the pull rope 74 around the circumference of the winding ring 72. The pull rope 74 pulls the fixing ring 73 close to the winding ring 72. When the pushing mechanism 6 pushes the pushing plate 711 to rotate, the two adjacent filter frames 5 are fitted together. The pull rope 74 can be used to pull the filter frames 5 one by one toward the pressing plate 4 until the pushing mechanism 6 has pushed all the pushing plates 711. After completion, the separation between all the adjacent filter frames 5 is completed, and the filter cake between the two adjacent filter frames 5 falls off. The pushing mechanism 6 only needs to move forward all the time to complete the separation and unloading of all the filter frames 5, thereby improving the separation efficiency between the filter frames 5.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
