Technical Field

[0001] The utility model relates to the technical field of composite film edge trimming, in particular to composite film edge trimming equipment. Background Art

[0002] Composite membranes are separation membranes composed of a microporous membrane or ultrafiltration membrane as a support layer, covered with a dense, homogeneous membrane with a thickness of only 0.1 to 0.25 μm as a barrier layer. This significantly increases the permeability of substances. Composite membrane materials include any possible combination of materials, such as ceramic membranes over metal oxides or aromatic polyamide films over polysulfone microporous membranes. Both flat and rolled membranes require non-woven reinforcement to support the microporous membrane's pressure resistance, while hollow fiber membranes do not.

When in normal use, the second conveying roller 4 still needs to have a rotating conveying effect. In order to avoid the presence of the groove 7 affecting the composite film and avoid scratches on the composite film, the connecting plate 5 provided at this time can just fill the groove 7 under the elastic force of the spring 6, so that the second conveying roller 4 just forms a roller-like structure.

[0032] Furthermore, the driving mechanism includes a second motor 19 and a second screw 22. A second turntable 21 is fixedly installed on the surface of the second screw 22 near the middle position.

The winding shaft 10 can reel in the cut waste edge. When the composite film needs to be cut directly, the composite film can be directly rolled up. The composite film is laid flat on the support plate 27, and then its two ends are respectively set on the two second conveying rollers 4, and the grooves 7 on the surfaces of the two second conveying rollers 4 are located at the bottom, the composite film is tightened and located inside the grooves 7, and then the second cylinder 29 is started. The second cylinder 29 drives the movable plate 28 to move upward, and the two pressure rods 30 on the surface of the movable plate 28 are pressed into the grooves 7 to fix the composite film. At this time, the auxiliary mechanism can be used to move the T-shaped block 25 to trim the static fixed composite film, thereby enhancing practicality. The two T-shaped rods 18 can use the driving mechanism to adjust the distance between them, so as to facilitate the cutting of composite films of different widths. In order to facilitate the collection and removal of waste edges, when winding around the reel 10, The worm gear 12 is driven by the first screw 11 to rotate, and the first screw 11 drives the two long rods 8 to extend out of the long slot 15, and then the winding shaft 10 and the long rod 8 are used to reel in the waste edge. When the reeling is completed, the handle is turned in the opposite direction so that the two long rods 8 are stored in the inside of the long slot 15. At this time, the waste edge can be easily taken out from the winding shaft 10. The groove 7 is provided on the second conveying roller 4 to facilitate the fixing operation of the composite film. When in normal use, the second conveying roller 4 still needs to play the role of rotation and conveying.
