In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] As Figure 1 shown, a film material winding device includes a frame 1, a plurality of guide rollers 2 provided on the frame 1, and a friction roller 3. The guide roller 2 is used to guide the slit film material into the friction roller 3, and the film material passing through the friction roller 3 then enters the winding shaft 4 for winding. The winding shaft 4 used here is an air-expansion shaft. On the frame 1, there is also Figure 2 a winding mechanism 5 for positioning the winding shaft 4 and performing rotational winding;

[0036] a flying knife mechanism 6 for cutting the film material on the wound winding shaft 4 and performing a starting winding operation on the newly placed winding shaft 4, and the cutting and starting winding operations can be carried out simultaneously;

[0037] a lower winding mechanism 7 for unwinding the wound winding shaft 4, that is, separating the winding shaft 4 from the device and transporting it to other areas;

[0038] an upper winding mechanism for transporting the newly placed winding shaft 4 to a designated position;

[0039] an upper winding mechanism for transporting the newly placed winding shaft 4 to a designated position;

[0040] As shown Figure 4 in the figure, on the rack 1, there are a winding-up position I, a rewinding position II and a coil-down position III. The winding-up mechanism places the newly placed winding shaft 4 into the winding-up position I. The flying knife mechanism 6 moves above the winding-up position I to wind the film material onto the newly placed winding shaft 4 and at the same time cuts the film material on the winding shaft 4 that has completed winding. The rewinding mechanism 5 sends the winding shaft 4 that has completed winding to the coil-down position III for coil-down operation by the coil-down mechanism 7. At the same time, the flying knife mechanism 6 resets. Then, the rewinding mechanism 5 moves to the winding-up position I to clamp the newly placed winding shaft 4 and moves to the rewinding position II for rewinding operation. Then, the winding-up mechanism continues with the winding-up operation. In this way, the whole process can run in a cyclic and automated manner, which can greatly save time and reduce labor.

[0041] As shown Figure 1 in the figure, the rack 1 includes a first side plate 11 and a second side plate 12 which are oppositely arranged. At the same time, a plurality of rack support rods 13 are arranged between the first side plate 11 and the second side plate 12. Among them, 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 rotate passively.

[0042] The rewinding mechanism 5 includes two rewinding guide rails arranged on the rack 1, namely a first rewinding guide rail 51 and a second rewinding guide rail 52. The first rewinding guide rail 51 is fixed on the first side plate 11, and the second rewinding guide rail 52 is fixed on the second side plate 12. Among them, a first guide groove is arranged on the first rewinding guide rail 51, and a second guide groove 521 (as shown Figure 3 in the figure) is arranged on the second rewinding guide rail 52. The winding shaft 4 straddles the first rewinding guide rail 51 and the second rewinding guide rail 52. At both ends of the winding shaft 4, a first bearing 41 and a second bearing 42 are respectively arranged (as shown Figure 5 in the figure). The first bearing 41 is arranged in the first guide groove and can roll therein. The second bearing 42 is arranged in the second guide groove 521 and can roll therein. Moving clamping groups are arranged on both the first side plate 11 and the second side plate 12. At the same time, a moving clamping group is configured beside each of the first rewinding guide rail 51 and the second rewinding guide rail 52. The moving clamping group is used to clamp the end of the winding shaft 4 and drive the winding shaft 4 to roll synchronously in the first guide groove and the second guide groove 521.

[0043] As shown Figure 5The shown moving clamping group includes a moving clamping seat 53, a first slide rail and slider group 54 arranged between the moving clamping seat 53 and the frame 1, a moving motor assembly for driving the movement of the moving clamping seat 53, a clamping cylinder 55 arranged on the moving clamping seat 53, and a winding clamping plate 56 arranged on the shaft part of the clamping cylinder 55. A winding driving assembly for driving the winding shaft 4 to rotate is arranged on the moving clamping seat 53. First, the moving motor assembly drives the moving clamping seat 53 to move to the starting winding position I. At this time, the winding clamping plate 56 is located above the winding shaft 4. The clamping cylinder 55 moves so that the winding clamping plate 56 moves downward to clamp the winding shaft 4. A third bearing 43 is arranged on the winding shaft 4, and the winding clamping plate 56 clamps on the third bearing 43. An arc is arranged on the winding clamping plate 56, and the arc just catches the outer ring of the third bearing 43 without affecting the rotation of the winding shaft 4 itself. Then the moving motor assembly reverses to move the moving clamping seat 53 to the winding position II, and the winding shaft 4 is driven to rotate by itself through the winding driving assembly, so as to realize the winding of the film material. Finally, after the winding is completed, the winding driving assembly stops rotating, and the moving motor assembly drives the moving clamping seat 53 to move to the unwinding position III. The clamping cylinder 55 moves upward to release the winding shaft 4. At this position, a slope 522 is provided at the first winding guide rail 51 and the second winding guide rail 52 (as Figure 3 shown), and the winding shaft 4 automatically rotates along the slope 522 to the unwinding mechanism 7, and the unwinding operation can be carried out.

[0044] Among them, as Figure 7 shown, the moving motor assembly includes a plurality of winding moving pulleys 57 arranged on the frame 1 and a moving motor 59. A winding moving belt 58 is arranged on the plurality of winding moving pulleys 57. The moving clamping seat 53 is fixed on the winding moving belt 58 and can move along with the winding moving belt 58. In order to ensure that the winding moving belts 58 on both sides drive the moving clamping seat 53 to move synchronously, there is one moving motor 59, and the moving connecting rod 510 is used to synchronously drive the winding moving pulleys 57 on both sides to rotate.

[0045] As Figure 5 with Figure 6The shown rewinding drive assembly includes a rewinding clutch, a rewinding motor 517, and a first rewinding rotating member 5112 disposed on the rewinding clutch. Among them, the rewinding clutch includes a first rewinding sleeve 511 fixed to the moving clamping seat 53, a second rewinding sleeve 512 fixed to the first rewinding sleeve 511, a rotating sleeve 513 disposed within the first rewinding sleeve 511, a rewinding rotating shaft 514 disposed within the rotating sleeve 513, a rewinding slider 518 disposed within the second rewinding sleeve 512, and a rewinding ejecting cylinder 519 disposed on the second rewinding sleeve 512. A fourth bearing 5110 connects the rotating sleeve 513 and the first rewinding sleeve 511. The rewinding slider 518 is connected to the rewinding rotating shaft 514. A spline connection exists between the rotating sleeve 513 and the rewinding rotating shaft 514 and the rewinding rotating shaft 514 can move axially. The rewinding ejecting cylinder 519 drives the rewinding slider 518 to move axially within the second rewinding sleeve 512. Therefore, the rewinding slider 518 drives the rewinding rotating shaft 514 to move axially within the first rewinding sleeve 511. At the same time, in order to ensure relative rotation between the rewinding rotating shaft 514 and the rewinding slider 518, a fifth bearing 5111 connects the rewinding rotating shaft 514 and the rewinding slider 518. A first rewinding pulley 515 is disposed on the rotating sleeve 513, a second rewinding pulley 516 is disposed on the moving clamping seat 53, and a rewinding belt is disposed on the first rewinding pulley 515 and the second rewinding pulley 516. The rewinding motor 517 drives the second rewinding pulley 516 to rotate. A rewinding tension pulley 5114 is disposed on the moving clamping seat. Among them, a first rewinding rotating member 5112 is disposed at the end of the rewinding rotating shaft 514 close to the rewinding shaft 4. A first spline tooth is disposed at the end of the first rewinding rotating member 5112. A second rewinding rotating member 5113 is disposed at the end of the rewinding shaft 4. A second spline tooth is disposed at the end of the second rewinding rotating member 5113. The first spline tooth meshes with the second spline tooth. First, the rewinding ejecting cylinder 519 pushes the rewinding slider 518 to move towards the rewinding shaft 4 within the second rewinding sleeve 512 and pushes the rewinding rotating shaft 514 to move towards the rewinding shaft 4, causing the first rewinding rotating member 5112 on the rewinding rotating shaft 514 to contact the second rewinding rotating member 5113 on the rewinding shaft 4, thereby causing the first spline tooth to mesh with the second spline tooth. After that, the rewinding motor 517 drives the second rewinding pulley 516 to rotate through the speed reducer 5115, drives the first rewinding pulley 515 to rotate through the rewinding belt, and further drives the rewinding rotating shaft 514 to rotate through the rotating sleeve 513, causing the rewinding shaft 4 to rotate and starting the rewinding operation.

When the winding shaft 4 is located at the winding position I, the film cutting knife group 66 and the winding roller 67 are located directly above the winding shaft 4 through the first flying knife cylinder 63 and the second flying knife cylinder 65. At this time, the film material is wrapped around the winding shaft 4 for more than 1 / 2 of the circumference. In actual operation, the film material is wrapped around the winding shaft 4 for 3 / 4 of the circumference; wherein, the flying knife rotating shaft 61 is arranged between the first side plate 11 and the second side plate 12, the first flying knife rotating plate 62 has two respectively arranged at the two ends of the flying knife rotating shaft 61, and the second flying knife rotating plate 6 4 is also provided with two, two first flying knife rotating plates 62 and two second flying knife rotating plates 64 are rotatably connected in a one-to-one manner, and three winding rollers 67 are provided, all of which are arranged between the two second flying knife rotating plates 64, one of the winding rollers 67 is close to the film cutting knife group 66, and at the same time, a clearance chamber is formed between the three winding rollers 67, the film cutting knife group 66 and the electrostatic group 68 are arranged in the clearance chamber, and the three winding rollers 67 can stretch the film material to avoid the clearance chamber when in contact with the film material; the film cutting knife group 66 includes a third flying knife cylinder 661 arranged between the two second flying knife rotating plates 64, and a third flying knife cylinder 661 arranged between the two second flying knife rotating plates 64.

At this time, the film cutting knife group 66 and the winding roller 67 are located directly above the winding shaft 4.

[0047] At the same time, if Figure 8 As shown, an electrostatic group 68 for charging the film material is provided on the second flying knife rotating plate 64. The electrostatic group 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.

[0048] The newly placed take-up reel 4 is placed at the take-up position I through the upper winding mechanism and presses the film material below the take-up reel 4. At this time, the flying knife mechanism 6 moves upward and passes through the lower part of the film material, and jacks up the film material upward through the take-up roller 67. When the take-up roller 67 is above the take-up reel 4, most of the area of the take-up reel 4 is wrapped by the film material. At the same time, the static electricity group 68 discharges electricity to make the film material charged and adsorbed on the take-up reel 4. The air film knife group moves to cut the film material.

The first fixing screw 7254 is fixed on the first surface 72521, and the adjusting screw 7253 abuts against the first surface 72521. A threaded waist hole is arranged on the second surface 72522, and the second fixing screw 7255 is fixed in the threaded waist hole. The setting direction of the threaded waist hole is parallel to the setting direction of the adjusting screw 7253. After adjusting the distance that the adjusting block 7252 protrudes by the adjusting screw 7253, it is fixed and positioned by the first fixing screw 7254 and the second fixing screw 7255 to complete the adjustment.

[0052] During the rewinding stage, the lower coiling plate 712 is located upward at the outlet of the ramp 522 of the first rewinding guide rail 51 and the second rewinding guide rail 52. The rewinding shaft 4 is transported to the ramp 522. At this time, the fork linear cylinder 727 drives the fork groove 725 on the fork plate 723 to insert into both ends of the rewinding shaft 4. The fork rotating cylinder 724 moves to drive the fork rotating plate 722 to rotate, so as to drive the rewinding shaft 4 to move downward along the ramp 522 into the lower coiling groove 715 through the fork plate 723. Then, the lower coiling cylinder 714 drives the lower coiling rotating plate 713 to rotate, thereby driving the lower coiling rotating shaft 711 to rotate. The rotation of the lower coiling rotating shaft 711 drives the lower coiling plate 712 to rotate downward. When it rotates to the specified position, the rewinding shaft 4 can be removed manually or by machine; then a new rewinding shaft 4 is placed in. The lower coiling cylinder 714 drives the lower coiling plate 712 to return to the previous position, waiting for the upper coiling mechanism to perform the upper coiling operation.

[0053] As Figures 13 - 17 shown, the upper coiling mechanism includes a lifting group 81, a moving group 82 and a positioning group 83. The lifting group 81 lifts the newly placed rewinding shaft 4 from the lower coiling mechanism 7 to the first position. The moving group 82 receives the rewinding shaft 4 at the first position and moves it to the second position. The positioning group 83 receives the rewinding shaft 4 at the second position and transports it to the starting coiling position I to complete the upper coiling operation.

[0054] Among them, as Figure 13 shown, the lifting group 81 includes a lifting shaft 811 arranged on the frame 1, a lifting plate 812 fixed on the lifting shaft 811, a lifting rotating plate 813 fixed on 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 rewinding shaft 4. As Figure 14The lifting groove 815 includes an arc segment 8151, a gentle slope segment 8152 connected to the arc segment 8151, and a limiting segment 8153. The gentle slope segment 8152 is located on the side of the arc segment 8151 close to the lifting shaft 811, and the limiting segment 8153 is located on the side of the arc segment 8152 away from the lifting shaft 811. The gentle slope segment 8152 can guide the winding shaft 4 into the arc segment 8151. When the winding shaft 4 disengages from the lower winding groove 75, at this time, the limiting segment 8153 can prevent the winding shaft 4 from disengaging from the lifting groove 815. At the same time, a lifting limiting groove 8154 can be arranged in the lifting groove 815 to accommodate the first bearing 41 or the second bearing 42 on the winding shaft 4, limit the movement of the winding shaft 4 in the axial direction, and improve the precision of upper winding. Two lifting plates 812 are arranged at both ends of the lifting shaft 811 respectively. The lifting cylinder 814 drives the lifting rotating plate 813 to rotate, so that the lifting shaft 811 rotates, and the lifting shaft 811 drives the lifting plate 812 to swing. The lifting cylinder 814 and the lifting rotating plate 813 form a group, and there are two groups respectively arranged at both ends of the lifting shaft 811 to realize the synchronous drive of the lifting shaft 811. The lower winding plate 72 of the lower winding mechanism 7 moves the newly placed winding shaft 4 to the side of the first winding guide rail 51 and the second winding guide rail 52. The lifting cylinder 814 makes the lifting plate 812 rotate. At this time, the winding shaft 4 is on the movement path of the lifting groove 815 on the lifting plate 812. The winding shaft 4 enters the lifting groove 815 and disengages from the lower winding groove 75 and moves to the first position along with the lifting groove 815, waiting for the moving group 82.

[0055] As Figure 15 And Figure 16 The moving group 82 shown in the figure includes a moving frame 821, a moving cylinder 822 arranged on the moving frame 821, a moving plate 823 arranged on the shaft of the moving cylinder 822, a second slide rail slider group 824 arranged between the moving plate 823 and the moving frame 821, and a third slide rail slider group 825 arranged between the moving frame 821 and the frame 1. A moving groove 826 for carrying the winding shaft 4 is arranged on the moving plate 823, and a moving drive group for driving the movement of the moving frame 821 is arranged on the frame 1. First, the moving drive group transports the moving frame 821 to the lifting groove 815 (i.e., the first position). At this time, the moving groove 826 is located below the lifting groove 815. The moving cylinder 822 contracts to make the moving plate 823 move upward. While the moving groove 826 moves upward, it lifts the winding shaft 4. After the moving cylinder 822 contracts in place, the winding shaft 4 disengages from the lifting groove 815. At this time, the moving drive group drives the moving frame 821 above the positioning group 83. In order to maintain balance, two groups of moving groups 82 are arranged on the first side plate 11 and the second side plate 12 respectively. Among them, there can be two groups of moving drive groups respectively used to control the moving group 82 on one side. In this solution, in order to ensure the synchronous movement of the moving groups 82 on both sides, one group of moving drive groups is adopted.

[0056] As shown Figure 15 The moving drive group includes a plurality of upper winding moving pulleys 827 arranged on the frame 1, an upper winding moving belt 828 arranged 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, upper winding moving pulleys 827 and upper winding moving belts 828 are also arranged in cooperation. 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, and thus the moving frame 821 can move synchronously.

[0057] As shown Figure 17 The positioning group 83 is provided with two groups respectively beside the first side plate 11 and the second side plate 12. The positioning group 83 includes a positioning rotating shaft arranged on the frame 1, a positioning rotating plate 831 arranged on the positioning rotating shaft, a first positioning cylinder 832 for driving the positioning rotating plate 831 to rotate, a positioning rotating rod 833 arranged on the positioning rotating plate 831, and a second positioning cylinder 834 for 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 extends upward to form a positioning extension end 835. The positioning rotating rod 833 is on the other side of the positioning rotating plate 831. A positioning accommodating cavity 836 with an open top is formed between the positioning extension end 835 and the positioning rotating rod 833. The winding shaft 4 can be placed in the positioning accommodating cavity 836. First, the positioning rotating plate 831 moves upward so that the opening of the positioning accommodating cavity 836 faces upward. The moving cylinder 822 in the moving group 82 drives the moving plate 823 to move downward to the second position, so that the moving groove 826 drives the winding shaft 4 into the positioning accommodating cavity 836. When the moving groove 826 is completely separated from the winding shaft 4, the second positioning cylinder 834 drives the positioning rotating rod 833 to rotate to clamp the winding shaft 4. Then, the first positioning cylinder 832 drives the positioning rotating plate 831 to rotate so that the opening of the positioning accommodating cavity 836 becomes horizontal. At this time, the winding shaft 4 is located at the starting winding position I and presses the film material below the winding shaft 4. Then, the moving clamping seat 53 of the winding mechanism 5 moves to the starting winding position I, and the clamping cylinder 55 drives the winding clamping plate 56 to move downward to clamp the winding shaft 4. At this time, the second positioning cylinder 834 contracts, so that the positioning rotating rod 833 opens, and the winding mechanism 5 can drive the winding shaft 4 to the winding position II.

[0058] Based on the above structure, multiple such film winding devices can be set up and respectively cooperate with the slitter. When the slitter cuts the film material into two pieces, two corresponding film winding devices are set up. If it is cut into three pieces, three film winding devices are set up, thus combining into a slitting and winding system.

[0059] In summary, first, the newly placed take-up reel 4 is moved to the ends of the first take-up guide rail 51 and the second take-up guide rail 52 through the lower winding groove 75 of the lower winding mechanism 7. Then, the take-up reel 4 is moved to a specified height through the lifting groove 815 in the lifting group 81. After that, the take-up reel 4 is moved above the positioning group 83 through the moving groove 826 in the moving group 82 and the take-up reel 4 is placed into the positioning receiving cavity 836 in the positioning group 83. The positioning receiving cavity 836 clamps the take-up reel 4 and rotates it to the starting winding position I. At this time, the flying knife mechanism 6 moves upward and winds the film material around the take-up reel 4 through the starting winding roller 67, and at the same time cuts the film material through the film cutting knife group 66. Then, the winding mechanism 5 transports the take-up reel 4 that has been wound 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 take-up reel 4 and conveys the newly placed take-up reel 4 to the winding position II to start winding; at the same time, the lower winding mechanism 7 lowers the take-up reel 4 that has been wound through the lower winding groove 75. At this time, a new take-up reel 4 can be placed in the lower winding groove 75, and the lower winding mechanism 7 moves the take-up reel 4 to the ends of the first take-up guide rail 51 and the second take-up guide rail 52 to continue the whole cycle.

[0060] The above-mentioned upper winding, starting winding, film cutting, winding, and lower winding are all realized by this device for automated production. It can realize the simultaneous operation of automatic film cutting and automatic starting winding. Among them, winding and upper winding can also be carried out simultaneously, which greatly saves time, increases the winding efficiency, saves manpower at the same time, and reduces costs.

[0061] It should be emphasized that: the above are only the preferred embodiments of the present invention, and there is no any form of limitation to the present invention. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
