Description

Technical Field

[0001] The present invention relates to the technical field of composite films, and in particular to a composite film laminating device and method. Background Art

[0002] Composite membrane is a separation membrane composed of a microporous membrane or ultrafiltration membrane as a supporting layer, and a dense homogeneous membrane with a thickness of only 0.1 to 0.25 μm as a barrier layer on its surface, which greatly increases the permeability of substances.

[0003] During film production, in order to laminate films with different properties together, the films need to be laminated to obtain a composite film with two properties. The traditional film lamination process is to overlap two films and then feed the films into a hot pressing roller for hot pressing lamination. Since the hot pressing equipment has a certain temperature, the films need to be manually picked up when they are fed into the hot pressing equipment and collected after the hot pressing lamination is completed. When the operator touches the hot pressing equipment by mistake, it is easy to cause casualties to the operator. At the same time, when manually collecting the rolls that have been hot pressed and laminating, and when introducing the films into the hot pressing equipment, the films will be touched, which easily leaves pollutants carried by the operator on the composite film, and at the same time causes deformation damage to the hot pressed laminated films, affecting the quality of the composite film products.

[0037] Specifically, Figure 2 , Figure 7 and Figure 8As shown, the conveying mechanism includes an arc plate 22, and a tough sheet 37 is connected to the lower end of the arc plate 22.

The lifting bar 39 is slidably connected to one side of the vertical plate 8, and a U-shaped frame 26 is slidably connected to the lifting bar 39.

[0038] Specifically, Figure 2 , Figure 5 and Figure 7 As shown, a magnetic strip 38 is connected to the outside of the tough sheet 37, and a pressing column 24 is connected to the lifting frame 23. The pressing column 24 is arranged directly above the control button 33. This structure has the effect of pressing the control button 33. The magnetic strip 38 structure can attract the magnetic block 20.

[0039] Specifically, Figure 3 and Figure 7 As shown, a slide rail 30 is fixedly connected to one side of the vertical plate 8, a slide clamp 40 is slidably connected to the slide rail 30, and the slide clamp 40 is fixedly connected to one side of the lifting bar 39. By setting the slide rail 30, the stability of the slide clamp 40 and the lifting bar 39 sliding thereon is improved.

[0040] Specifically, Figure 2 , Figure 7 and Figure 8 As shown, one end of the U-shaped frame 26 is connected to a slide 31, and the lower end of the slide 31 is connected to a slider 41. The slider 41 is slidably connected to the lifting bar 39. By setting the lifting bar 39 structure, the slider 41 structure can move up and down and horizontally to achieve the effect of transferring the winding sleeve 11.

[0041] Specifically, Figure 6 , Figure 7 and Figure 8 As shown, a cylinder hoop 45 is fixedly connected to the outer side of the cylinder 27, and an axis is set on the outer side of the vertical plate 8. The cylinder hoop 45 is rotatably connected to the axis. One end of the cylinder hoop 45 is rotatably connected to the vertical plate 8. When the cylinder 27 is extended and retracted, the cylinder hoop 45 will rotate around the connection with the vertical plate 8. A push block 25 is fixedly connected to one end of the U-shaped frame 26. The telescopic end of the cylinder 27 is connected to a slide rod 42, and the slide rod 42 is rotatably connected to the slide cylinder 31.

[0042] Specifically, Figure 2 and Figure 8As shown, a recovery frame 36 is connected to one side of the slide 31, and a baffle 44 is connected to one end of the recovery frame 36. A paddle 43 is rotatably connected to one side of the baffle 44. The paddle 43 is rotatably connected to the recovery frame 36. A torsion spring is connected to the connection between the recovery frame 36 and the paddle 43. By setting the torsion spring structure, the paddle 43 can be reset from an inclined state to a vertical state when it is not limited by the composite film, so as to facilitate the subsequent separation between the winding sleeve 11 and the rotating shaft 15. When the cylinder 27 is extended to the maximum distance, the paddle 43 has completed the reset.

[0043] In summary, the composite film laminating device and method provided in the present embodiment, when the composite film needs to be laminated, the composite films to be laminated are overlapped and introduced from the left side of the hot pressing roller 3, and then the composite film laminated by the hot pressing roller 3 is placed on the winding sleeve 11, the telescopic member 5 is controlled to extend, and the composite film is pressed against the winding sleeve 11 by the lower pressing roller 6. This operation step is the manual operation part, and the composite film scraps of this section of composite film laminated and wound on the winding sleeve 11 need to be removed later;

[0044] When performing composite film lamination processing, the operator needs to control the extension of the cylinder 27, use the cylinder 27 to push the slide bar 42 to slide on the L-shaped groove 29, use the slide bar 42 to drive the slider 41 to rise in height, and use the slider 41 to drive the lifting bar 39 to rise in height. At this time, the arc plate 22 connected to the lifting frame 23 on one side of the lifting bar 39 rises in height, wherein the arc plate 22 cooperates with the toughness sheet 37 to complete the effect of clamping the winding sleeve 11. The above structure simultaneously clamps the winding sleeve 11 and lifts it to be flush with the leftmost rotating shaft 15. At this time, the leftmost rotating shaft 15 will move to the highest point after the turntable 10 rotates 90°;

[0045] The cylinder 27 continues to extend, and the slide bar 42 enters the horizontal part of the L-shaped groove 29. At this time, the height of the lifting bar 39 stops rising, and the slider 41 structure starts to slide on the lifting bar 39. Since the slider 41 is connected to the U-shaped frame 26 through the slide tube 31, the slider 41 structure drives the U-shaped frame 26 to move toward the rotating shaft 15. The push block 25 connected to one end of the U-shaped frame 26 pushes the winding sleeve 11 placed in the arc plate 22 to move. Since the position of the arc plate 22 remains unchanged, the winding sleeve 11 is separated from the arc plate 22. At this time, the winding sleeve 11 is The push block 25 pushes and docks with the rotating shaft 15, wherein the rotating shaft 15 is provided with ribs on the outside and the winding sleeve 11 is provided with a limiting piece 28 inside, so as to avoid slipping when the rotating shaft 15 drives the winding sleeve 11 to rotate. When the winding sleeve 11 docks with the rotating shaft 15, the limiting piece 28 abuts against the ribs on the outside of the rotating shaft 15. Since the two ends of the limiting piece 28 are inclined structures, when the two structures dock, the winding sleeve 11 will rotate at a small angle, thereby avoiding the situation that the winding sleeve 11 and the rotating shaft 15 cannot dock;

[0046] A tough sheet 37 structure is connected below the arc plate 22. The tough sheet 37 has a tendency to shrink to an arc-shaped structure, and the tough sheet 37 has the effect of carrying the winding sleeve 11. The winding sleeve 11 used for winding composite films is mostly made of plastic or paper materials, so its gravity has a small load on the tough sheet 37. The arc plate 22 cooperates with the tough sheet 37 to easily complete the height lifting and transfer of the winding sleeve 11.

[0047] A magnetic strip 38 structure is connected to the outside of the tough sheet 37. When the arc plate 22 drops in height and docks with the conveyor 16, the magnetic strip 38 connected to the outside of the tough sheet 37 will be attracted by the magnetic block 20 structure on the outside of the conveyor 16, forcing the tough sheet 37 to deform from an arc shape to a vertical plate-like structure. At this time, the tough sheet 37 falls and can cover the winding sleeve 11 located in the conveyor 16. The tough sheet 37 structure will bend along the inner wall structure of the conveyor 16 to cover the winding sleeve 11. At this time, the pressing column 24 structure will press the control button 33. The control button 33 has the effect of controlling the power off of the magnetic block 20. When the magnetic block 20 is powered off, When the magnet block 20 is powered on, the structure is magnetic. When the control button 33 is pressed, the magnet block 20 is powered off, that is, when the tough sheet 37 falls, the magnet block 20 is magnetic, and when the tough sheet 37 falls to the lowest point, the magnet block 20 is not magnetic. A damping block 35 structure is provided on one side of the control button 33, so that when the control button 33 is pressed, it will slowly return to the pop-up state. At this time, when the tough sheet 37 drives the winding sleeve 11 to rise in height in the early stage, the control button 33 is still pressed. At this time, the magnet block 20 will not attract the magnetic strip 38, forcing the tough sheet 37 to deform, thereby ensuring that the winding sleeve 11 can be transferred stably;

[0048] When the winding sleeve 11 is pushed to dock with the rotating shaft 15, the height of the lower pressure roller 6 is lowered, and the composite film is pressed down to abut against the winding sleeve 11. At this time, the winding motor 13 starts to rotate, thereby pulling the composite film and winding it on the winding sleeve 11. During the winding process, the cylinder 27 contracts. The cylinder 27 is a reciprocating telescopic motion. When the cylinder 27 is extended to the maximum distance, the cylinder 27 immediately starts to contract. When the cylinder 27 contracts, the paddle 43 can be used to pry the rightmost winding sleeve 11 away from the rotating shaft 15. When the paddle 43 moves toward the winding sleeve 11, the paddle 43 will be limited by the composite film wound on the winding sleeve 11 and deflected. When the paddle 43 moves to the point where it is not in contact with the composite film, the paddle 43 is structurally reset to a vertical state under the action of the torsion spring. When the paddle 43 is moved in the reverse direction, the paddle 43 is limited by the stop bar 44, so the paddle 43 cannot deflect and the winding sleeve 11 is separated from the rotating shaft 15. At this time, the winding sleeve 11 with the composite film wound thereon freely falls into the collection basket disposed below to complete the collection.

[0049] When the winding sleeve 11 completes the winding operation after the composite film is bonded, the central motor 12 rotates 90°, the telescopic member 5 and the cutting plate 7 are lowered in height, and the lower pressure roller 6 connected to one end of the telescopic member 5 presses the composite film down to contact the next winding sleeve 11 to be wound. At this time, the internal blade of the cutting plate 7 slides along the cutting plate 7, so that the wound winding sleeve 11 is separated from the winding sleeve 11 to be wound, thereby realizing the effect of automatically separating the wound composite film. When the composite film is wound next time, no manual operation is required, thereby realizing the automated winding operation after the composite film is bonded, and realizing the effect of automated traction of the composite film, ensuring that the composite film is also stably tractioned, thereby improving the efficiency of composite film bonding, avoiding manual operation pollution during the composite film bonding process, and improving the composite film bonding quality.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
