[0055] The flexible film material delivery and cutting equipment can be part of a flexible film material production and processing line. Upstream of the flexible film material delivery and cutting equipment can be a flexible film material punching equipment, and downstream of the flexible film material delivery and cutting equipment can be a flexible film material heat sealing equipment.

[0056] The flexible membrane material 10 is punched and then conveyed to a cutting device for cutting. The cut flexible membrane material 10 is then sent to a heat-sealing device for heat sealing. Preferably, the flexible membrane material 10 can be a medical or non-medical type, including but not limited to highly absorbent non-woven fabric. Figure 2 As shown, 11 indicates the punching position of the flexible membrane material 10, and 12 indicates the punching residue corresponding to the punching position, which can be collected by a collection device.

[0057] In some embodiments, the delivery of the flexible film material to the cutting device includes:

[0058] The frame 30 is mainly used for the installation of the functional mechanism for feeding flexible film material to the cutting equipment. The conveyor belt 20 mentioned above can also be driven to move by the conveyor roller mechanism installed on the frame 30.

[0060] The clamping mechanism 50, mounted on the frame 30, is used to clamp the second part of the flexible film 10 and the part of the conveyor belt 20 opposite to the second part, and cooperates with the attraction mechanism 40 to deliver the flexible film 10 to a predetermined position as the conveyor belt 20 moves.

[0061] For example, the uncutable flexible film material 10 is conveyed to position a, the suction mechanism 40 returns to its initial position, and then the cutting mechanism 70 cuts the flexible film material 10. The cut single pieces of flexible film material 10 are then conveyed by the downstream conveyor belt 90, such as to a flexible film material heat sealing equipment for heat sealing processing. The suction mechanism 40 then returns to its initial position.

The output end of the first drive member 645 is connected to a third synchronous pulley 647, and the second synchronous pulley 646 and the third synchronous pulley 647 are connected by a second synchronous belt 648.

[0069] The first driving member 645 drives the third synchronous wheel 647 to rotate, which in turn causes the second synchronous wheel 646 to rotate, thereby driving the first synchronous wheel assembly to work, so that the attraction mechanism 40 and the clamping mechanism 50 move together.

[0070] Preferably, the first driving component 645 is a servo motor, and the servo motor has high adjustment accuracy.

[0071] In some embodiments, the attraction mechanism 40 includes a mounting base 41, a mounting shaft 42, a swing cylinder 43, a swing rod 44, an attraction member 45, and a second drive member 46;

Both ends of the suction element 45 are connected to the opposite faces of the two swing rods 44, and this connection can be detachable, such as by threaded connection. Preferably, the suction element 45 is a needle-type suction cup.

[0075] Preferably, the second driving member 46 is connected to the swing cylinder 43 and is used to drive the swing cylinder 43 to rotate, thereby causing the suction member 45 to move upward or downward. The suction member 45 can attract a portion of the flexible film material 10 or move it away from the flexible film material.

[0076] Combination Figure 7 As shown, the suction mechanism 40 includes a mounting plate 47 mounted on a fixed plate 63, which may be mounted at the middle position of the fixed plate 63.

[0077] Preferably, the second drive member 46 is mounted on the mounting plate 47, and the output end of the second drive member 46 is connected to the connecting portion 431 of the oscillating cylinder 43 through the ring head member 48. Each oscillating cylinder 43 has a plate-shaped connecting portion 431 near the other oscillating cylinder 43. Both connecting portions 431 have through holes at their ends away from the oscillating cylinder 43. The ring portion of the ring head member 48 extends between the two connecting portions 431. A rotating shaft passes through the through hole and the ring portion to connect the connecting portion 431 to the ring head member 48, and then the second drive member 46 is connected to the oscillating cylinder 43.

[0078] The second driving element 46 can be a drive motor or a cylinder. In some embodiments, when a drive motor is used, the drive motor can be connected to the swing cylinder 43 via a lead screw drive assembly.

[0079] Combination Figure 8As shown, the clamping mechanism 50 includes a positioning plate 51 connected to the fixed plate 63, and a stop 52 connected to the end of the positioning plate 51 away from the fixed plate 63. The stop 52 is located below the conveyor belt 20. There can be one or two positioning plates 51. When two are provided, both positioning plates 51 are connected to the end of the fixed plate 63 near the inner side of the guide rail 61. The stop 52 has a long strip structure, and its surface facing the conveyor belt 20 can be planar to ensure sufficient contact area. Preferably, the length direction of the stop 52 is perpendicular to the moving direction of the flexible film 10.

[0080] The clamping mechanism 50 also includes a third driving member 53 connected to the fixed plate 63. The output end of the third driving member 53 is connected to a pressure block 54, which is located above the flexible film material 10. The third driving member 53 drives the pressure block 54 to move up and down. Preferably, two third driving members 53 can be provided, and the pressure block 54 can be a long strip structure. The pressure block 54 can be located at the corresponding position of the stop block 52, and both ends of the pressure block 54 are connected to the output ends of the two third driving members 53. Preferably, the length direction of the pressure block 54 is perpendicular to the moving direction of the flexible film material 10.

[0081] Preferably, the surface of the pressure block 54 facing the flexible film 10 can be planar to ensure sufficient contact area.

[0082] The third driving member 53 drives the pressure block 54 to move downward, so as to cooperate with the stop block 52 to clamp and fix the flexible film 10 and the opposite part of the conveyor belt 20 together, so that the flexible film 10 can move with the conveyor belt 20; the third driving member 53 drives the pressure block 54 to move upward away from the flexible film 10, so that the clamping mechanism 50 returns to its original position.

[0083] Preferably, the third driving component 53 can be a pneumatic cylinder or a hydraulic cylinder.

[0084] See Figures 9 to 14 In some embodiments, the flexible film material delivery and cutting device further includes a cutting mechanism 70 for cutting the flexible film material 10;

[0085] The cutting mechanism 70 includes a cutting track 71 disposed on the frame 30, the length direction of the cutting track 71 being perpendicular to the moving direction of the flexible film 10; and two second synchronous pulley assemblies 72 disposed on both sides of the frame 30 and located in the length direction of the cutting track 71, and a third synchronous belt 723 connecting the two second synchronous pulley assemblies 72.

[0088] Furthermore, the cutting mechanism 70 also includes a cutting assembly 77 connected to the third synchronous belt 723;

[0089] The fourth driving component 73 drives the second synchronous wheel assembly 72 to rotate, thereby driving the cutting component 77 to move along the cutting track 71 to cut the flexible film material 10.

[0090] Preferably, the fourth driving component 73 can be a servo motor.

[0091] In some embodiments, the cutting assembly 77 includes a base 771 connected to a third synchronous belt 723, a cutting blade holder 772 disposed on the base 771, and a cutting blade 773 disposed on the cutting blade holder 772; the cutting assembly 77 also includes a fifth driving member 774 for driving the cutting blade 773 to rotate. Preferably, the fifth driving member 774 is a servo motor.

[0092] The fourth drive component 73 and the fifth drive component 774 cooperate with each other to ensure that the forward speed of the cutting component 77 matches the tangential speed at the cutting edge of the cutting blade 773. The tangential speed at the cutting edge of the cutting blade 773 is slightly greater than or equal to the forward speed of the cutting component 77, which helps to ensure their cutting quality.

[0093] Preferably, the cutting track 71 is provided with a moving channel 711 arranged along its length direction, and the base 771 and the third synchronous belt 723 can be placed in the moving channel 711, which provides a moving guide space.

[0094] The base 771 can be a plate-like structure. The cutting blade holder 772 is connected to the base 771 via a support member 7711. The base 771 is provided with a cutting groove 7712. The cutting blade 773 is disposed opposite to the cutting groove 7712, and the lower end of the cutting blade 773 can extend into the cutting groove 7712. Preferably, the base 771 may also be provided with a pulley assembly 7713, so that the resistance is reduced when the base 771 contacts the cutting track 71.

[0095] Preferably, the flexible film material delivery and cutting device further includes a bracket 80 mounted on the frame 30. The bracket 80 may include a lower beam 82 and a support beam 83 arranged opposite to each other. Multiple support beams 83 may be provided. The lower beam 82 may be installed on the upper end of the support beam 83 by a fastener. The cutting track 71 may be arranged on the lower beam 82.

[0096] Furthermore, the cutting mechanism 70 also includes a guide rod 78 disposed on the bracket 80 and arranged parallel to the cutting track 71; the guide rod 78 may be installed on the upper end of the support beam 83 through a structure such as a connecting seat.

[0097] Preferably, the guide rod 78 is provided with a guide member 79 that can move along the axial direction of the guide rod 78, and the guide member is connected to the cutting blade holder 772 through a connector 710.

[0098] The operating principle of this flexible film material delivery and cutting equipment is as follows:

[0099] like Figure 2 As shown: The flexible film material 10 is located on the cutting track 71, and the suction element 45 of the suction mechanism 40 presses the flexible film material 10 onto the cutting track 71. The fourth drive element 73 and the fifth drive element 774 start and run simultaneously at a certain proportional speed. The fourth drive element 73 drives the fourth synchronous belt 76, which in turn drives the third synchronous belt 723 to move. The third synchronous belt 723 drives the cutting assembly 77 to move on the cutting track 71. At the same time, the fifth drive element 774 drives the cutting blade 773 to rotate and cut. After the flexible film material 10 is cut laterally, the fourth drive element 73 moves in the opposite direction, driving the cutting assembly 77 back to its original position or initial position, ready for the next work cycle. The flexible film material 10 cut into single pieces is then transported by the conveyor belt 90 of the flexible film material heat sealing equipment to the flexible film material heat sealing equipment for heat sealing processing. It should be noted that the conveyor belt 90 of the flexible film material heat sealing equipment and the conveyor belt 20 for delivering the flexible film to the cutting equipment are driven by their respective drive mechanisms.

[0100] After the cutting assembly 77 returns to its initial position, the suction member 45 picks up the flexible film 10 and lifts it up. The clamping mechanism 50 then clamps the corresponding part of the flexible film 10 with the conveyor belt 20 (at this time, the dual-shaft powder clutch 644 is de-energized). As the conveyor belt 20 feeds the flexible film 10 forward, it also feeds the suction mechanism 40 and the clamping mechanism 50 forward together. After being delivered to the correct position (e.g., the front end of the flexible film 10 to be cut is delivered to position a), the suction member 45 releases the flexible film 10, and the clamping mechanism 50 opens, that is, the stop block 52 separates from the pressure block 54. The conveyor belt 20 remains stationary, and the suction mechanism 40 and the clamping mechanism 50, driven by the drive mechanism 60 (at this time, the dual-shaft powder clutch 644 is energized), return to the starting position, that is, the suction member 45 is at the cutting track 71 position, and it presses down to fix the flexible film 10 (the front end of the suction member 45 is at position b in the figure), so that the cutting assembly 77 can cut the flexible film 10.

[0101] Understandably, the flexible membrane material 10 is entirely supported and conveyed by the conveyor belt 20 to avoid uneven force on the flexible membrane material 10 during the conveying process, which would affect the conveying quality (wrinkling, longitudinal stretching and lateral shrinking, offset, etc.).

[0102] Meanwhile, the cutting mechanism 70, which uses a combination of dual drive components such as dual servo control for cutting, has the advantage of not producing lint.

[0103] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
