[0040] The detailed embodiments shown below are intended to be descriptive of various configurations of the inventive subject matter and are not intended to represent the only configurations in which the inventive subject matter can be practiced. The detailed embodiments include specific details for the purpose of providing a thorough understanding of the inventive subject matter. However, it will be apparent to those skilled in the art that the inventive subject matter can be practiced without

[0041] It is to be understood that the terminology used herein such as "first" and "second", etc. is intended to distinguish one entity or operation from another entity or operation, and is not intended to denote that any actual relationship or order exists between the entities or operations.

[0042] The terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0043] Referring to Figs. 1 to 5 As shown in the figure, a filter membrane processing device comprises a frame 1;

[0044] A flattening assembly 2 is arranged on the frame 1 and conveys the filter membrane to be cut;

[0045] A cutting assembly 3 cuts the filter membrane to be cut flattened by the flattening assembly 2;

[0046] A discharge assembly 4 discharges the filter membrane cut by the cutting assembly 3;

[0047] and a collection box 5 collects the filter membrane discharged by the discharge assembly 4

[0048] The flattening assembly 2 comprises an upper flattening roller 21 and a lower flattening roller 22, and a flattening channel 23 is formed between the upper flattening roller 21 and the lower flattening roller 22.

[0049] The cutting assembly 3 comprises a rotating shaft 31 rotatably connected to the frame 1, and the rotating shaft 31 is provided with a cutting knife 32 for cutting the filter membrane to be cut. The linear speed of the cutting knife 32 driven to rotate by the rotating shaft 31 is equal to the linear speed of the filter membrane to be cut driven by the flattening assembly 2.

[0050] In some embodiments, the rotating direction of the cutting knife 32 is the same as the moving direction of the filter membrane to be cut. That is, when the filter membrane to be cut moves from left to right, the rotating direction of the cutting knife 32 should be counterclockwise rotation, so that the cutting knife 32 does not cause the filter membrane to be cut to stop when cutting the filter membrane to be cut, thereby preventing the filter membrane to be cut from being wrinkled.

[0051] Referring to Figs. 1 to 5 In some embodiments, one cutting knife 32 can be arranged on the rotating shaft 31, and a plurality of cutting knives 32 can also be arranged on the rotating shaft 31. In actual cutting process, since the rotating action of the cutting knife 32 is only to prevent the filter membrane to be cut from being wrinkled, the cutting knife 32 does not have a fixed length function.

[0052] When it is necessary to cut off the filter membrane to be cut at a set length, the movement mode of the cutting knife 32 is intermittent movement, that is, after the filter membrane to be cut is conveyed for a set length, the cutting knife 32 is rotated to cut off the filter membrane to be cut.

[0053] In some embodiments, since the cutting knife 32 does not move synchronously with the filter membrane to be cut, the specific number of the cutting knife 32 is not limited, as long as the linear speed of the cutting knife 32 rotating is equal to the linear speed of the filter membrane to be cut moving.

[0056] Alternatively, the strength of the cutting knife 32 is greater than the strength of the support 11, so as to prevent the cutting knife 32 from being damaged.

[0057] Referring to Figs. 1 to 5As shown, in some embodiments, the rack 1 is further provided with a support frame 12 for supporting the filter membrane to be cut, the support frame 12 is located on the side of the flattening assembly 2 away from the cutting assembly 3, the upper surface of the support frame 12 is flush with the upper surface of the support 11, and the upper surface of the support 11 is flush with the bottom surface of the flattening channel 23.

[0058] In some embodiments, the support frame 12 is used to assist in supporting the filter membrane to be cut, so that the filter membrane to be cut enters the flattening channel 23 in the correct position. Therefore, a correction plate or a correction groove can be arranged on the support frame 12.

[0059] The correction plate or the correction groove is used to correct the position of the filter membrane to be cut relative to the flattening channel 23.

[0060] In some embodiments, the rack 1 is further provided with a guide plate 13, the filter membrane discharged by the discharging assembly 4 enters the receiving box 5 through the guide plate 13, and the filter membrane sliding along the guide plate 13 enters the receiving box 5 under the action of its own gravity.

[0061] The guide plate 13 is used to guide the cut filter membrane, and the guide plate 13 can be welded to the rack 1, or the guide plate 13 can be fixed to the rack 1 by other connection methods, for example, the guide plate 13 can be fixed to the rack 1 by bolts.

[0062] Referring to Figs. 1 to 5 As shown, in some embodiments, the discharging assembly 4 includes an upper discharging roller 41 and a lower discharging roller 42, a discharging channel 43 is formed between the upper discharging roller 41 and the lower discharging roller 42, and the guide plate 13 is inclined along the tangential direction of the lower discharging roller 42.

[0063] In some embodiments, the upper pressing roller 21 drives the upper discharging roller 41 through a gear transmission mechanism, and the linear speed of the upper pressing roller 21 is equal to the linear speed of the upper discharging roller 41.

[0064] In some embodiments, the gear transmission mechanism includes a driving gear 211 arranged on the upper pressing roller 21 and a driven gear 411 arranged on the upper discharging roller 41, a reversing gear 6 is arranged between the driving gear 211 and the driven gear 411, and the rotation direction of the upper pressing roller 21 is the same as the rotation direction of the upper discharging roller 41.

[0065] In some embodiments, the upper pressing roller 21 drives the lower pressing roller 22 through a gear, and the upper discharging roller 41 drives the lower discharging roller 42 through a gear.

[0066] Referring to Figs. 1 to 5As shown, in some embodiments, rolling bearings can be arranged between the upper discharging roller 41 and the frame 1, and between the lower discharging roller 42 and the frame 1. Rolling bearings can also be arranged between the upper pressing roller 21 and the frame 1, and between the lower pressing roller 22 and the frame 1.

[0067] Rolling bearings should be arranged between the gears and the frame 1.
