Description

Technical Field

[0001] This invention relates to the field of roll winding technology, and in particular to a fully automatic winding machine and a slitting and winding system having the same. Background Technology

[0002] A winding machine is used to wind processed film materials into rolls. It is mainly used after slitting machines and is often used for winding non-woven fabrics, mica tape, paper, insulating materials and various thin film materials.

[0003] Currently, most rewinding machines on the market consist of a frame, several guide rollers, friction rollers, and a take-up roller, all driven by a motor. During rewinding, the film material needs to be manually attached to the take-up roller before the roller rotates to rewind. After rewinding, the film material needs to be cut and unwound. After removing the roll, a new take-up roller is installed, and the rewinding process is repeated, thus continuing the production cycle. However, this method requires manual rewinding and installation of new take-up rollers, and the rewinding can only begin after the unwound roll is completed. This process is time-consuming, significantly reducing production efficiency and increasing labor costs. Summary of the Invention

[0045] like Figure 1 and Figure 2 The membrane winding device shown includes a frame 1, a plurality of guide rollers 2 and friction rollers 3 disposed on the frame 1. The guide rollers 2 are used to guide the slit membrane material into the friction rollers 3. The membrane material passing through the friction rollers 3 then enters the winding shaft 4 for winding. The winding shaft 4 used here is an air-expanding shaft. The frame 1 also includes...

[0046] The winding mechanism 5 is used to position the winding shaft 4 and can rotate and wind it up.

[0047] The flying knife mechanism 6 is used to cut the film material on the winding shaft 4 after it has been wound up and to start the winding operation of the newly inserted winding shaft 4. The cutting and winding operations can be performed simultaneously.

[0048] The unwinding mechanism 7 is used to unwind the completed winding shaft 4, that is, to remove the winding shaft 4 from the device and transport it to other areas;

[0049] The winding mechanism is used to transport the newly inserted take-up shaft 4 to the designated position;

[0050] like Figure 4 The frame 1 shown is equipped with a starting position I, a take-up position II, and a lowering position III. The upper winding mechanism places the newly placed take-up spool 4 into the starting position I. The flying knife mechanism 6 moves above the starting position I and winds the film material onto the newly placed take-up spool 4 while simultaneously cutting the film material on the already wound take-up spool 4. The take-up mechanism 5 sends the wound take-up spool 4 to the lowering position III for the lowering mechanism 7 to perform the lowering operation. At the same time, the flying knife mechanism 6 resets. Then, the take-up mechanism 5 moves to the starting position I to clamp the newly placed take-up spool 4 and moves to the take-up position II for the winding operation. After that, the upper winding mechanism continues the upper winding operation. In this way, the entire process can be automatically and repeatedly, which can greatly save time and reduce manpower.

[0051] like Figure 1 The frame 1 shown includes a first side plate 11 and a second side plate 12 arranged opposite to each other, and a plurality of frame support rods 13 are arranged between the first side plate 11 and the second side plate 12. The guide roller 2 and the friction roller 3 are fixed between the first side plate 11 and the second side plate 12, and the guide roller 2 and the friction roller 3 can be passively rotated.

[0052] The winding mechanism 5 includes two winding guide rails mounted on the frame 1, namely a first winding guide rail 51 and a second winding guide rail 52. The first winding guide rail 51 is fixed to the first side plate 11, and the second winding guide rail 52 is fixed to the second side plate 12. A first guide groove is provided on the first winding guide rail 51, and a second guide groove 521 is provided on the second winding guide rail 52 (e.g., ...). Figure 3 As shown), the take-up shaft 4 spans across the first take-up guide rail 51 and the second take-up guide rail 52.

A winding drive assembly for driving the winding shaft 4 to rotate is disposed on the movable clamping seat 53. First, the movable motor assembly drives the movable clamping seat 53 to move to the starting position I.

The plate 56 moves downward to clamp the take-up shaft 4, and the take-up shaft 4 is provided with a third bearing 43. The take-up clamping plate 56 clamps on the third bearing 43. The take-up clamping plate 56 is provided with an arc shape, which just fits with the outer ring of the third bearing 43 without affecting the rotation of the take-up shaft 4 itself. Then, the moving motor assembly reverses to move the moving clamping seat 53 to the take-up position II. The take-up drive assembly drives the take-up shaft 4 to rotate, thereby realizing the take-up of the film material. Finally, after the take-up is completed, the take-up drive assembly stops rotating, and the moving motor assembly drives the moving clamping seat 53 to move to the lower take-up position II. The clamping cylinder 55 moves upward to release the take-up shaft 4. At this position, the first take-up guide rail 51 and the second take-up guide rail 52 are at a ramp 522 (e.g., Figure 3 As shown, the take-up shaft 4 automatically rotates along the ramp 522 to the unwinding mechanism 7, where the unwinding operation can be performed.

[0054] Among them, such as Figure 7 The shown mobile motor assembly includes several winding moving pulleys 57 and a mobile motor 59 mounted on the frame 1. A winding moving belt 58 is mounted on the winding moving pulleys 57. The mobile clamping seat 53 is fixed on the winding moving belt 58 and can move with the winding moving belt 58.

A take-up ejection cylinder 519 is mounted on the second take-up sleeve 512. The rotating sleeve 513 is connected to the first take-up sleeve 511 by a fourth bearing 5110. The take-up slider 518 is connected to the take-up rotating shaft 514. The rotating sleeve 513 and the take-up rotating shaft 514 are splined and the take-up rotating shaft 514 is axially movable. The take-up ejection cylinder 519 drives the take-up slider 518 to move axially within the second take-up sleeve 512. Therefore, the take-up slider 518 drives... The winding rotating shaft 514 moves axially within the first winding sleeve 511; simultaneously, to ensure relative rotation between the winding rotating shaft 514 and the winding slider 518, a fifth bearing 5111 connects the winding rotating shaft 514 and the winding slider 518; a first winding pulley 515 is provided on the rotating sleeve 513, a second winding pulley 516 is provided on the movable clamping seat 53, and a winding belt is provided on the first winding pulley 515 and the second winding pulley 516.

First, the take-up ejector cylinder 519 pushes the take-up slider 518 to move towards the take-up shaft 4 within the second take-up sleeve 512, and pushes the take-up rotating shaft 514 to move towards the take-up shaft 4, so that the first take-up rotating component 5112 on the take-up rotating shaft 514 contacts the second take-up rotating component 5113 on the take-up shaft 4, thereby making the first and second toothed teeth mesh. Then, the take-up motor 517 drives the second take-up pulley 516 to rotate through the reducer 5115, drives the first take-up pulley 515 to rotate through the take-up belt, and then drives the take-up rotating shaft 514 to rotate through the rotating sleeve 513, so that the take-up shaft 4 rotates and the take-up operation begins.

The first flying knife rotating plate 62 is arc-shaped to facilitate the feeding of the second flying knife rotating plate 64 towards the take-up shaft 4. The second flying knife rotating plate 64 is rotatably connected to... On the first flying knife rotating plate 62, and on the second flying knife rotating plate 64, a winding roller 67 is provided. When the take-up shaft 4 is in the winding position I, the film cutting knife assembly 66 and the winding roller 67, controlled by the first flying knife cylinder 63 and the second flying knife cylinder 65, are located directly above the take-up shaft 4. At this time, the film material wraps around the take-up shaft 4 for more than 1 / 2 of the circumference.

The flying knife rotating shaft 61 is located between the first side plate 11 and the second side plate 12. There are two first flying knife rotating plates 62, which are respectively located at both ends of the flying knife rotating shaft 61. 4.

Three winding rollers 67 are provided, all disposed between the two second flying knife rotating plates 64. One of the winding rollers 67 is close to the film cutting knife assembly 66. At the same time, a clearance chamber is formed between the three winding rollers 67. The film cutting knife assembly 66 and the electrostatic assembly 68 are disposed in the clearance chamber. When the three winding rollers 67 come into contact with the film material, they can spread the film material to avoid the clearance chamber. The film cutting knife assembly 66 includes a third flying knife cylinder 661 disposed between the two second flying knife rotating plates 64 and a third flying knife cylinder 661 disposed between the two second flying knife rotating plates 64. The flying knife cylinder 661 has a flying knife holder 662 and a flying knife blade 663 fixed on the flying knife holder 662. The third flying knife cylinder 661 is a rodless cylinder. The third flying knife cylinder 661 drives the flying knife holder 662 to drive the flying knife blade 663 to slide along the axial direction of the take-up shaft 4, and the flying knife blade 663 cuts the film material. The first flying knife cylinder 63 drives the first flying knife rotating plate 62 to rotate upward. After rotating to the position, the second flying knife cylinder 65 drives the second flying knife rotating plate 64 to rotate upward until the second flying knife rotating plate 64 is above the newly placed take-up shaft 4. At this time, the film cutting knife assembly 66 and the take-up roller 67 are directly above the take-up shaft 4.

[0057] At the same time, such as Figure 8 As shown, an electrostatic assembly 68 for charging the film material is provided on the second flying knife rotating plate 64. The electrostatic assembly 68 includes an electrostatic mounting bracket provided on the second flying knife rotating plate 64, an electrostatic generator provided on the electrostatic mounting bracket, and a discharge rod.

[0058] The newly inserted take-up spool 4 is placed into the take-up position I through the upper winding mechanism, and the membrane material is pressed under the take-up spool 4. At this time, the flying knife mechanism 6 moves upward and pushes the membrane material upward from below through the take-up roller 67. When the take-up roller 67 is above the take-up spool 4, most of the area of ​​the take-up spool 4 is covered by the membrane material. At the same time, the electrostatic group 68 discharges, causing the membrane material to become charged and adsorbed onto the take-up spool 4. The air-film knife group moves to cut the membrane material. After that, the flying knife mechanism moves downward to complete the take-up operation of the take-up spool and the cutting operation of the membrane material.

[0059] like Figure 4 The unwinding mechanism 7 shown includes an unwinding receiving group 71 and an unwinding fork group 72. The take-up shaft 4 is located near the exit of the first take-up guide rail 51 and the second take-up guide rail 52. The unwinding fork group 72 positions the two ends of the take-up shaft 4 and pushes the two ends of the take-up shaft 4 to move synchronously. When the take-up shaft 4 leaves the exit, the unwinding receiving group 71 receives the take-up shaft 4 to perform the unwinding operation.

A lower winding limiting groove is provided in the lower winding groove 715, which is used to position the first bearing 41 or the second bearing 42 on the take-up shaft 4. The lower winding plate 712 is provided with... Two plates are respectively located at both ends of the lower winding rotating shaft 711; two lower winding plates 712 are respectively located at both ends of the lower winding rotating shaft 711; the lower winding plate 712 includes a first plate 7121 fixed on the lower winding rotating shaft 711 and a second plate 7122 connected to the first plate 7121, the lower winding groove is provided on the second plate 7122, the first plate 7121 and the second plate 7122 form an obtuse angle and the second plate 7122 is curved upward; at the same time, reinforcing ribs are provided on the side of the lower winding plate 712 to ensure sufficient support force when the winding shaft 4 is lowered.

[0061] like Figure 11The lower winding fork assembly 72 shown includes a fork rotation shaft 721 mounted on the frame 1, a fork rotation plate 722 mounted on the fork rotation shaft 721, a fork plate 723 mounted on the fork rotation plate 722, and a fork rotation cylinder 724 for driving the fork rotation plate 722 to rotate. There are two fork rotation plates 722, two fork plates 723, and two fork rotation cylinders 724, located on opposite sides of the frame 1. A fork groove 725 for accommodating the winding shaft 4 is provided on the top of the fork plate 723. A fourth slide rail slider assembly 726 is provided between the fork rotation plate 722 and the fork plate 723. The shift fork plate 723 can slide on the shift fork rotating plate 722. A shift fork linear cylinder 727 is provided on the shift fork rotating plate 722, driving the movement of the shift fork plate 723. The shift fork groove 725 is formed by two protruding ends 7251 extending upwards from the top of the shift fork plate 723, and is located between the two protruding ends 7251. The two shift fork grooves 725 can be engaged with both ends of the take-up shaft 4. To accommodate take-up shafts 4 of different diameters, an adjusting element for adjusting the size of the shift fork groove 725 is provided on the protruding ends 7251 within the shift fork groove 725. Figure 12 The adjusting component shown includes an adjusting block 7252, a fixing screw, and an adjusting screw 7253. The adjusting screw 7253 passes through the protruding end 7251 and abuts against the adjusting block 7252. By adjusting the length of the adjusting screw 7253, the size of the shift fork groove 725 can be adjusted. The fixing screw includes a first fixing screw 7254 and a second fixing screw 7255. The adjusting block 7252 includes a first surface 72521 and a second surface 72522 that are perpendicular to each other. The first fixing screw 7254 is fixed to the first surface 72521, and the adjusting screw 7253 abuts against the first surface 72521. A threaded hole is provided on the second surface 72522, and the second fixing screw 7255 is fixed in the threaded hole. The direction of the threaded hole is parallel to the direction of the adjusting screw 7253. The distance of the extending part of the adjusting block 7252 is adjusted by adjusting the adjusting screw 7253, and then fixed and positioned by the first fixing screw 7254 and the second fixing screw 7255 to complete the adjustment.

[0062] During the winding stage, the lower winding plate 712 is positioned upwards at the exit of the ramp 522 between the first winding guide rail 51 and the second winding guide rail 52. The winding shaft 4 is transported to the ramp 522. At this time, the linear cylinder 727 drives the fork groove 725 on the fork plate 723 to insert into both ends of the winding shaft 4. The rotating cylinder 724 moves, causing the rotating plate 722 to rotate. This causes the winding shaft 4 to move downwards along the ramp 522 into the lower winding groove 715. Then, the lower winding cylinder 714 drives the rotating plate 713 to rotate, thereby causing the rotating shaft 711 to rotate. The rotating shaft 711 rotates, causing the lower winding plate 712 to rotate downwards. When it reaches the designated position, the winding shaft 4 can be removed manually or by machine. After that, a new winding shaft 4 is placed in, and the lower winding cylinder 714 drives the lower winding plate 712 to return to the previous position, waiting for the upper winding mechanism to perform the upper winding operation.

[0063] like Figures 13-17 The winding mechanism shown includes a lifting group 81, a moving group 82, and a positioning group 83. The lifting group 81 lifts the newly placed take-up shaft 4 from the lower winding mechanism 7 to a first position. The moving group 82 takes over the take-up shaft 4 at the first position and moves to a second position. The positioning group 83 takes over the take-up shaft 4 at the second position and transports it to the starting position I to complete the winding operation.

[0064] Among them, such as Figure 13 The lifting assembly 81 shown includes a lifting shaft 811 mounted on the frame 1, a lifting plate 812 fixed to the lifting shaft 811, a lifting rotating plate 813 fixed to the lifting shaft 811, and a lifting cylinder 814 for driving the lifting rotating plate 813 to rotate. The end of the lifting plate 812 away from the lifting shaft 811 is provided with a lifting groove 815 for accommodating the winding shaft 4. Figure 14The lifting groove 815 includes an arc-shaped section 8151, a gentle slope section 8152 connected to the arc-shaped section 8151, and a limiting section 8153. The gentle slope section 8152 is located on the side of the arc-shaped section 8151 closer to the lifting shaft 811, and the limiting section 8153 is located on the side of the arc-shaped section 8152 away from the lifting shaft 811. The gentle slope section 8152 can guide the take-up shaft 4 into the arc-shaped section 8151, and when the take-up shaft 4 disengages from the lower winding groove 75, the limiting section 8153 can prevent the take-up shaft 4 from disengaging from the lifting groove 815. At the same time, a lifting limiting groove 8154 can be provided in the lifting groove 815 to accommodate the first bearing 41 or the second bearing 42 on the take-up shaft 4, restricting the movement of the take-up shaft 4 in the axial direction and improving the accuracy of winding. The lifting plate 812 is provided with two Located at both ends of the lifting shaft 811, the lifting cylinder 814 drives the lifting rotating plate 813 to rotate, causing the lifting shaft 811 to rotate. The lifting shaft 811 drives the lifting plate 812 to swing. The lifting cylinder 814 and the lifting rotating plate 813 form a group, which are two groups respectively set at both ends of the lifting shaft 811 to realize synchronous driving of the lifting shaft 811. The lower winding plate 72 of the lower winding mechanism 7 moves the newly placed take-up shaft 4 to the side of the first take-up guide rail 51 and the second take-up guide rail 52. The lifting cylinder 814 causes the lifting plate 812 to rotate. At this time, the take-up shaft 4 is located on the movement path of the lifting groove 815 on the lifting plate 812. The take-up shaft 4 enters the lifting groove 815 and disengages from the lower winding groove 75. It moves with the lifting groove 815 to the first position, waiting for the moving group 82.

[0065] like Figure 15 and Figure 16 The movable assembly 82 shown includes a movable frame 821, a movable cylinder 822 mounted on the movable frame 821, a movable plate 823 mounted on the shaft of the movable cylinder 822, a second slide rail slider assembly 824 mounted between the movable plate 823 and the movable frame 821, and a third slide rail slider assembly 825 mounted between the movable frame 821 and the frame 1. The movable plate 823 has a movable groove 826 for supporting the winding shaft 4. A movable drive assembly for driving the movable frame 821 is mounted on the frame 1. First, the movable drive assembly transports the movable frame 821 to the lifting groove 815 (i.e., the first position). At this time, the movable frame 821... The movable groove 826 is located below the lifting groove 815. When the movable cylinder 822 retracts, the movable plate 823 moves upward. At the same time as the movable groove 826 moves upward, the take-up shaft 4 is lifted. After the movable cylinder 822 retracts to its position, the take-up shaft 4 disengages from the lifting groove 815. At this time, the movable drive group drives the movable frame 821 to the top of the positioning group 83. In order to maintain balance, the movable group 82 is set in two sets, located on the first side plate 11 and the second side plate 12 respectively. The movable drive group can have two sets, each used to control the movable group 82 on one side. However, in this scheme, in order to ensure that the movable groups 82 on both sides move synchronously, only one movable drive group is used.

[0066] like Figure 15 The shown moving drive assembly includes several upper winding moving pulleys 827 mounted on the frame 1, an upper winding moving belt 828 mounted on the upper winding moving pulleys 827, and a moving rodless cylinder 829. The moving part of the moving rodless cylinder 829 is fixed on the upper winding moving belt 828, and the moving frame 821 is fixed on the upper winding moving belt 828. On the other side, an upper winding moving pulley 827 is also provided to cooperate with the upper winding moving belt 828. The upper winding moving pulleys 827 on both sides are connected by a moving connecting rod 8210, so that the upper winding moving pulleys 827 on both sides can rotate synchronously, thereby enabling the moving frame 821 to move synchronously.

[0067] like Figure 17 The positioning assembly 83 shown has two sets located next to the first side plate 11 and the second side plate 12, respectively. The positioning assembly 83 includes a positioning rotating shaft mounted on the frame 1, a positioning rotating plate 831 mounted on the positioning rotating shaft, a first positioning cylinder 832 driving the positioning rotating plate 831 to rotate, a positioning rotating rod 833 mounted on the positioning rotating plate 831, and a second positioning cylinder 834 driving the positioning rotating rod 833 to rotate. The positioning rotating shaft is coaxial with the friction roller 3. One side of the positioning rotating plate 831 has an upwardly extending positioning extension end 835, and the positioning rotating rod 833 is on the other side of the positioning rotating plate 831. A top-opening positioning receiving cavity 836 is formed between the positioning extension end 835 and the positioning rotating rod 833, and the winding shaft 4 can be placed inside this positioning receiving cavity 836. First, the positioning rotating plate 831 moves upward to make the positioning receiving cavity... With the opening of cavity 836 facing upwards, the moving cylinder 822 in the moving assembly 82 drives the moving plate 823 to move downwards to the second position, so that the moving groove 826 carries the take-up shaft 4 into the positioning cavity 836. After the moving groove 826 is completely disengaged from the take-up shaft 4, the second positioning cylinder 834 drives the positioning rotating rod 833 to rotate and clamp the take-up shaft 4. Then, the first positioning cylinder 832 drives the positioning rotating plate 831 to rotate, so that the opening of the positioning cavity 836 becomes horizontal. At this time, the take-up shaft 4 is located at the starting position I and the film material is pressed under the take-up shaft 4. Then, the moving clamping seat 53 of the take-up mechanism 5 moves to the starting position I, and the clamping cylinder 55 drives the take-up clamping plate 56 to move downwards to clamp the take-up shaft 4. At this time, the second positioning cylinder 834 retracts, so that the positioning rotating rod 833 opens, and the take-up mechanism 5 can drive the take-up shaft 4 to the take-up position II.

[0068] Based on the above structure, multiple film winding devices can be set up, each of which cooperates with a slitting machine. When the slitting machine cuts the film into two strips, two sets of film winding devices are set up accordingly. If it is cut into three strips, three sets of film winding devices are set up, thus forming a slitting and winding system.

[0069] In summary, firstly, the newly placed take-up shaft 4 is moved to the end of the first take-up guide rail 51 and the second take-up guide rail 52 via the lowering groove 75 of the lowering mechanism 7. Then, the take-up shaft 4 is moved to a specified height via the lifting groove 815 in the lifting group 81. Next, the take-up shaft 4 is moved to the top of the positioning group 83 via the moving groove 826 in the moving group 82 and placed into the positioning receiving cavity 836 in the positioning group 83. The positioning receiving cavity 836 clamps the take-up shaft 4 and rotates it to the starting position I. At this time, the flying knife mechanism 6 moves upward and winds the film material around the take-up shaft via the starting roller 67. 4. Simultaneously, the film material is cut by the film cutting knife group 66. Then, the winding mechanism 5 transports the already wound winding shaft 4 to the lower winding position III to be received by the lower winding mechanism 7. After that, the winding mechanism 5 moves to the starting winding position I to clamp the newly placed winding shaft 4 and transports the newly placed winding shaft 4 to the winding position II to start winding. At the same time, the lower winding mechanism 7 lowers the already wound winding shaft 4 through the lower winding groove 75. At this time, another winding shaft 4 can be placed in the lower winding groove 75. The lower winding mechanism 7 moves the winding shaft 4 to the end of the first winding guide rail 51 and the second winding guide rail 52 to continue the whole cycle.

[0070] The aforementioned processes of winding, unwinding, film cutting, rewinding, and unwinding are all automated through this device. It can achieve simultaneous automatic film cutting and automatic unwinding, and rewinding and winding can also be performed simultaneously, which greatly saves time, increases winding efficiency, saves manpower, and reduces costs.

[0071] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
