[0034] The embodiment of the present application discloses a film laminating device for filter plate processing.

[0035] As Figure 1 shown, the film laminating device for filter plate processing includes a workbench 1, a conveying mechanism 2, a winding and unwinding mechanism 3, a film laminating mechanism 4 and a centering positioning mechanism 5.

[0036] As Figure 2 shown, the winding and unwinding mechanism 3 includes a winding roller 31, an unwinding roller 32 and a guiding roller 33. The winding roller 31 and the unwinding roller 32 are installed on the workbench 1. The winding roller 31 and the unwinding roller 32 are installed at the same horizontal height. There are two guiding rollers 33. The two guiding rollers 33 are arranged on the part of the workbench 1 between the winding roller 31 and the unwinding roller 32. The two guiding rollers 33 are respectively installed on both sides of the film laminating mechanism 4. The two guiding rollers 33 are arranged on the same horizontal plane. The film is installed on the unwinding roller 32 and is wound on the winding roller 31 after passing through the two guiding rollers 33.

[0037] As Figure 3 shown, the film covering mechanism 4 includes a bracket 41, a lifting cylinder 42, a circumferential cutting knife 43, a sliding rod 44, a limiting spring 45 and a pressing seat 46. The bracket 41 is installed on the workbench 1 and is arranged above the conveying mechanism 2. The lifting cylinder 42 is installed on the support frame and is directly above the middle part of the conveying mechanism 2. The circumferential cutting knife 43 is fixedly connected to the piston rod of the lifting cylinder 42. The pressing seat 46 is slidably connected inside the circumferential cutting knife 43. A plurality of sliding rods 44 and limiting springs 45 are provided. The plurality of sliding rods 44 are evenly installed on the circumferential part of the upper end surface of the pressing seat 46. One end of the sliding rod 44 is fixedly connected to the pressing seat 46, and the other end of the sliding rod 44 penetrates through the side wall of the circumferential cutting knife 43 and can slide relative to the circumferential cutting knife 43. The limiting spring 45 is sleeved on the sliding rod 44. One end of the limiting spring 45 is fixedly connected to the sliding rod 44, and the other end of the limiting spring 45 is fixedly connected to the upper end surface of the circumferential cutting knife 43.

The two limiting seats 53 are threadedly connected to the external threads 521 at both ends, so as to control the synchronous reverse centering movement of the two limiting seats 53 and position the filter at the centering part of the conveyor belt, thus facilitating the film covering process of the film covering mechanism 4.

[0041] The implementation principle of a film laminating device for filter processing in an embodiment of this application is as follows: The conveying mechanism 2 transports the filter to the processing position. The winding and unwinding mechanism 3 winds and unwinds the film. The driving motor 51 drives the driving lead screw 52 to rotate, and the driving lead screw 52 drives the limiting seats 53 on both sides to move synchronously and reversely, thereby centering and positioning the filter, facilitating the alignment of the filter with the film laminating mechanism 4, and improving the processing yield of the filter. One end of the sliding rod 44 is installed on the extrusion seat 46, the other end of the sliding rod 44 is slidably connected to the cutting ring knife 43, the extrusion seat 46 is slidably connected inside the cutting ring knife 43, the limiting spring 45 is sleeved on the sliding rod 44, one end of the limiting spring 45 is fixedly connected to the sliding rod 44, and the other end of the limiting spring 45 is connected to the cutting ring knife 43.
