Elastic membrane processing equipment and cutting device

Abstract

An elastic membrane processing device includes: a base, one end of which is used to hold an elastic membrane to be processed; a conveying device disposed on the base and acting on the elastic membrane to convey a portion of the elastic membrane toward the other end of the base; and a cutting device mounted on the end of the base opposite to the elastic membrane to cut the conveyed elastic membrane into a plurality of elastic filaments. The cutting device includes a cutting shaft and a plurality of circular blades arranged side-by-side on the cutting shaft and corresponding to a movement path of the elastic membrane.

Claims

1. A cutting device mounted on a base for cutting an elastic membrane material being conveyed through into a plurality of elastic filaments; the cutting device comprising: a cutting shaft; and a plurality of circular blades arranged side by side on the cutting shaft and corresponding to a movement path of the elastic membrane material.

2. The cutting device as claimed in claim 1, wherein the circular blades are spaced apart by a predetermined distance.

3. The cutting device as claimed in claim 1, wherein the blade shaft is fixed to the base so that the circular blades cannot rotate relative to the elastic membrane.

4. The cutting device as claimed in claim 1, wherein the blade shaft is pivotally mounted on the base in a rotatable manner, such that the circular blades can rotate relative to the elastic membrane as the blade shaft rotates.

5. The cutting device as claimed in claim 1, wherein the circular blades are integrally formed.

6. The cutting apparatus as claimed in claim 1, wherein the elastic membrane material includes a substrate portion and an upper functional portion and a lower functional portion disposed on opposite two side surfaces of the substrate portion; the substrate portion has at least one substrate layer, the substrate layer being formed of at least one polymer or copolymer; the upper functional portion and the lower functional portion each have at least one functional layer, the functional layer being formed of at least one polymer main component and a functional component.

7. The cutting apparatus as claimed in claim 6, wherein the substrate portion further includes an upper bonding layer and a lower bonding layer, respectively disposed on at least one side surface and another side surface of the substrate layer; the upper bonding layer is formed between the substrate portion and the upper functional portion, and the lower bonding layer is formed between the substrate portion and the lower functional portion.

8. An elastic membrane processing apparatus, comprising: a base, one end of which is used to hold an elastic membrane to be processed; a conveying device disposed on the base and acting on the elastic membrane to convey a portion of the elastic membrane toward the other end of the base; and a cutting device as described in any one of claims 1 to 7, mounted on the base opposite the elastic membrane to cut the conveyed elastic membrane into a plurality of elastic filaments.

9. The elastic film processing equipment as claimed in claim 8, wherein the conveying device includes a track and a roller assembly; the track is disposed between the elastic film and the cutting device, and the roller assembly acts on a portion of the elastic film to pull a portion of the elastic film along the track toward the cutting device.

10. The elastic film processing equipment as claimed in claim 9, wherein the roller assembly has a lower roller, an upper roller and a drive motor; one end of the lower roller has a lower gear; the upper roller is used to contact the elastic film, one end of which has an upper gear, and the upper gear meshes with the lower gear; the drive motor is connected to the lower roller and is controlled to drive the lower roller to move, thereby causing the upper roller to be driven to rotate synchronously.

11. The elastic membrane processing equipment as claimed in claim 9, wherein the conveying device further includes a clamping module disposed between the elastic membrane and the track; the height of the clamping module corresponds to the height of the track, for clamping a portion of the elastic membrane extending parallel to the track.

12. The elastic film processing equipment as claimed in claim 8 further includes a collecting device having a collecting rack adjacent to the cutting device and a plurality of winding units arrayed in the collecting rack; the winding units correspond to the elastic filaments respectively, for winding the cut elastic filaments thereon to form a plurality of elastic filament rolls.

13. The elastic film processing equipment as claimed in claim 12, wherein the collecting device further comprises a wire divider disposed between the cutting device and the collecting device; the wire divider has a plurality of wire dividing holes distributed in a dispersed manner for the elastic filaments to pass through and extend to the winding units.

14. The elastic membrane processing apparatus as claimed in claim 8, wherein the elastic membrane comprises a substrate portion and an upper functional portion and a lower functional portion disposed on opposite side surfaces of the substrate portion; the substrate portion has at least one substrate layer, the substrate layer being formed of at least one polymer or copolymer; the upper functional portion and the lower functional portion each have at least one functional layer, the functional layer being formed of at least one polymer main component and a functional component.

15. The elastic film processing equipment as claimed in claim 14, wherein the substrate portion further includes an upper bonding layer and a lower bonding layer, respectively disposed on at least one side surface and another side surface of the substrate layer; the upper bonding layer is formed between the substrate portion and the upper functional portion, and the lower bonding layer is formed between the substrate portion and the lower functional portion.
