Description

Technical Field

[0001] The present application relates to the technical field of waste film material winding, and in particular to a waste film material winding structure and a film material slitting device. Background Art

[0002] Before slitting, the film material includes an adhesive film and release films on opposite sides of the adhesive film. The adhesive film and the release film are stacked in sequence, wherein the adhesive film is sticky on both opposite sides, and the release film is not sticky. In order to use the film material more conveniently, the film material usually needs to be slid.

[0003] The main steps of film slitting in the related art are to tear off the release films on both sides of the adhesive film, and then cut the wider adhesive film into multiple adhesive sub-films of suitable width.

Therefore, the film material cut off from both sides of the adhesive film may become waste, but these wastes may be reused. In the related art, the waste of adhesive film is mainly rolled up manually, which greatly reduces the efficiency of rolling up the waste. Utility Model Content

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0047] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] See also Figure 1 The present application provides a waste film winding structure, which includes a first support plate 1, a first waste winding roller 2 and a second waste winding roller 7.

[0049] The first waste winding roller 2 is installed on the first supporting plate 1 and is used to wind up the first waste film 401 of the adhesive film 4 . The second waste winding roller 7 is installed on the first supporting plate 1 and is used to wind up the second waste film 402 of the adhesive film 4 .

[0050] The film material in this application is a material commonly used in the fields of industrial production, for example, the film material in this application includes but is not limited to composite material unidirectional tape. The film material is divided into an adhesive film 4 and release films on both sides of the adhesive film 4 after passing through the film separation assembly in the slitting equipment, wherein both sides of the adhesive film 4 are adhesive. Figure 2 After the adhesive film 4 passes through the slitting mechanism 5 in the slitting device, it is cut into an adhesive sub-film 403, a first waste film 401 and a second waste film 402. The first waste film 401 is the portion cut off from one side of the adhesive film 4, and the second waste film 402 is the portion cut off from the other side of the adhesive film 4. Generally, the widths of the first waste film 401 and the second waste film 402 are smaller than the width of the adhesive sub-film 403, and the first waste film 401 can be wider than the second waste film 402. Therefore, the first waste film 401 can be reused after being rolled up, and of course, the second waste film 402 can also be reused in some cases.

[0051] The adhesive sub-film 403 can be transferred to a subsequent winding device of the adhesive sub-film 403 through a transition roller 9. The number of transition rollers 9 can be multiple, and one transition roller 9 can transfer one adhesive sub-film 403. For example, Figure 1 Three transition rollers 9 are exemplified in the figure, and the three transition rollers 9 are arranged side by side on the first support plate 1 .

[0052] The surfaces of the first waste winding roller 2, the second waste winding roller 7 and the transition roller 9 are all subjected to anti-sticking treatment, for example, by plasma anti-sticking treatment, so that the first waste film 401 does not stick to the first waste winding roller 2, the second waste film 402 does not stick to the second waste winding roller 7, and the adhesive sub-film 403 does not stick to the transition roller 9.

[0053] The first waste winding roller 2 and the second waste winding roller 7 can both rotate around their own axes, so that at least part of the first waste film 401 is located on the first waste winding roller 2, and then the first waste winding roller 2 is rotated to continuously wind the first waste film 401 on the first waste winding roller 2; at least part of the second waste film 402 is located on the second waste winding roller 7, and then the second waste winding roller 7 is rotated to continuously wind the second waste film 402 on the second waste winding roller 7. Compared with the method of manually winding the first waste film 401 and the second waste film 402 in the related art, this embodiment can greatly improve the winding efficiency of the first waste film 401 and the second waste film 402.

[0054] Based on the above design, this embodiment uses the first waste winding roller 2 to roll up the first waste film 401 of the adhesive film 4, and the second waste winding roller 7 to roll up the second waste film 402 of the adhesive film 4, so as to improve the winding effect of the first waste film 401 and the second waste film 402, thereby greatly improving the winding efficiency of the film waste.

[0055] In some embodiments, see Figure 1 , Figure 3-Figure 5 The winding structure also includes a guide assembly installed on the first support plate 1 , and the guide assembly includes an adjustment unit 8 , a first connecting plate 23 and a guide pulley 25 .

[0056] The adjusting unit 8 is installed on the first supporting plate 1 , and the adjusting direction of the adjusting unit 8 is the same as the axial direction of the second waste winding roller 7 . The first connecting plate 23 is installed on the adjusting unit 8 , and the guide pulley 25 is installed on the first connecting plate 23 . The second waste film 402 is wound on the second waste winding roller 7 via the guide pulley 25 .

[0057] The second waste film 402 is wound on the second waste winding roller 7 after passing through the guide pulley 25. When the adjustment unit 8 moves along the axial direction of the second waste winding roller 7, the second waste film 402 can be driven to be wound on different positions of the second waste winding roller 7. In this way, the second waste film 402 can be wound on different positions of the second waste winding roller 7 more conveniently and evenly.

[0058] Preferably, the guide pulley 25 can be installed on the first connecting plate 23 via a rotating shaft, so that the guide pulley 25 can rotate around the rotating shaft. When the second waste film 402 is transmitted on the guide pulley 25, the guide pulley 25 can rotate, thereby reducing the friction between the second waste film 402 and the guide pulley 25, so that the second waste film 402 is not easily damaged.

[0059] In some embodiments, please refer again to Figure 3-Figure 5 The adjustment unit 8 includes a support frame 22, a screw rod 20 and a nut 21. The support frame 22 is installed on the first support plate 1. The screw rod 20 is installed on the support frame 22 through a bearing. The extension direction of the screw rod 20 is the same as the axial direction of the second waste winding roller 7. The nut 21 is threadedly connected to the screw rod 20, and the first connecting plate 23 is installed on the nut 21.

[0060] A connecting piece, such as a connecting ring, may also be installed on the nut 21 , so that the first connecting plate 23 can be more conveniently connected to the nut 21 through the connecting piece.

[0061] When the screw 20 is rotated, according to the working principle of the screw nut structure, it can be seen that the nut 21 will move along the screw 20. Since the nut 21 and the guide pulley 25 are connected by the first connecting plate 23, the nut 21 will drive the first connecting plate 23 and the guide pulley 25 to move along the screw 20 in turn. When the guide pulley 25 moves, the second waste film 402 can be transmitted to different positions of the second waste winding roller 7.

[0062] In some embodiments, please refer again to Figure 3-Figure 5 A power mechanism is installed at one end of the screw rod 20, and the power mechanism includes a first rotating motor 10, a first pulley 11 and a second pulley 13. The first rotating motor 10 is installed on the first support plate 1, the first pulley 11 is installed on the motor shaft of the first rotating motor 10, and the second pulley 13 is installed at one end of the screw rod 20. The second pulley 13 is connected to the first pulley 11 through a first belt 12.

[0063] The first rotary motor 10 is a conventional motor, and the installation method, circuit connection and working principle of the first rotary motor 10 are all known to those skilled in the art. The rotation of the first rotary motor 10 will drive the first pulley 11, the first belt 12 and the second pulley 13 to rotate in sequence, and the second pulley 13 will then drive the screw 20 to rotate, so that the screw 20 can be driven to rotate more efficiently, so that the second waste film 402 can be more efficiently and evenly rolled onto the second waste winding roller 7.

[0064] In some embodiments, please refer again to Figure 3 A third pulley 15 is installed at one end of the second waste winding roller 7, and the third pulley 15 is connected to the second pulley 13 through a second belt 14.

[0065] The first rotating motor 10 rotates to sequentially drive the first pulley 11, the first belt 12, the second pulley 13, the second belt 14 and the third pulley 15 to rotate, and the third pulley 15 then drives the second waste winding roller 7 to rotate. In this way, the second waste winding roller 7 can be rotated more efficiently, so that the second waste film 402 can be wound up more efficiently.

[0066] In some embodiments, please refer again to Figure 4 At least one set of first limiting rods 26 is installed on the support frame 22, and at least one set of second limiting rods 24 is installed on the first connecting plate 23. The second waste film 402 is wound on the second waste winding roller 7 through the first limiting rods 26, the second limiting rods 24 and the guide pulley 25 in sequence.

[0067] The first limiting rod 26 and the second limiting rod 24 guide and limit the second waste film 402 . The first limiting rod 26 and the second limiting rod 24 can more accurately transfer the second waste film 402 to the second waste winding roller 7 .

[0068] In some embodiments, please refer again to Figure 3 The winding structure also includes a second rotating motor 16 installed on the first support plate 1, a fourth pulley 17 is installed on the motor shaft of the second rotating motor 16, a fifth pulley 19 is installed at one end of the first waste winding roller 2, and a third belt 18 is connected between the fifth pulley 19 and the fourth pulley 17.

[0069] The second rotary motor 16 is a conventional motor, and the installation method, circuit connection and working principle of the second rotary motor 16 are all known to those skilled in the art. The second rotary motor 16 rotates to sequentially drive the fourth pulley 17, the third belt 18 and the fifth pulley 19 to rotate, and the fifth pulley 19 then drives the first waste winding roller 2 to rotate, so that the first waste film 401 can be more efficiently wound on the first waste winding roller 2.

[0070] In some embodiments, see Figure 6-Figure 8 The present application also provides a film material slitting device, which includes a waste film material winding structure and a slitting mechanism 5 as described in the present application. The slitting mechanism 5 is installed on the first support plate 1, and is used to slit the adhesive film 4 into a plurality of adhesive sub-films 403, and to slit the first side of the adhesive film 4 into a first waste film 401, and to slit the second side of the adhesive film 4 into a second waste film 402, wherein the width of the adhesive sub-film 403 is smaller than the width of the adhesive film 4.

[0071] The slitting mechanism 5 includes a first slitting roller 30, a second slitting roller 33, a first slitting knife 31 and a second slitting knife 32. The first slitting roller 30 and the second slitting roller 33 are both mounted on the first supporting plate 1, the first slitting knife 31 is mounted on the first slitting roller 30, and the second slitting knife 32 is mounted on the second slitting roller 33. The adhesive film 4 passes through the gap between the first slitting knife 31 and the second slitting knife 32 and contacts the first slitting knife 31 and the second slitting knife 32.

[0072] A third rotating motor 40 is mounted on the first supporting plate 1, a sixth pulley 41 is mounted on the motor shaft of the third rotating motor 40, a seventh pulley 43 and an eighth pulley 44 are also mounted on the first supporting plate 1 via a rotating shaft, a fourth belt 42 is connected between the sixth pulley 41 and the seventh pulley 43, a ninth pulley 45 is mounted on one end of the first film-slitting roller, a tenth pulley 47 is mounted on one end of the first slitting roller 30, a fifth belt 46 is connected between the eighth pulley 44, the ninth pulley 45 and the tenth pulley 47, a first gear 38 is mounted on the first slitting roller 30, and a second gear 39 meshing with the first gear 38 is mounted on the second slitting roller 33.

[0073] The third rotary motor 40 is a conventional product, and the installation method, circuit connection and working principle of the third rotary motor 40 are all known to those skilled in the art. The first slitting knife 31 and the second slitting knife 32 are conventional slitting knives, for example, the first slitting knife 31 includes a plurality of first blades, and there are gaps between the plurality of first blades, and the second slitting knife 32 includes a plurality of second blades, and there are gaps between the plurality of second blades, and the plurality of first blades correspond to the plurality of second blades one by one, so that it is easier to cut the adhesive film 4 into a plurality of adhesive sub-films 403, and the width of the adhesive sub-films 403 is substantially the same as the width of the gaps between the plurality of first blades.

[0074] When the third rotating motor 40 rotates, it will drive the sixth pulley 41, the fourth belt 42, the seventh pulley 43, the eighth pulley 44, the fifth belt 46, the ninth pulley 45 and the tenth pulley 47 to rotate in sequence. When the ninth pulley 45 rotates, it will drive the first film separating roller to rotate, thereby facilitating the rotation of the first film separating roller.

[0075] When the tenth pulley 47 rotates, it drives the first slitting roller 30 to rotate, and the first slitting roller 30 then drives the first gear 38, the second gear 39 and the second slitting roller 33 to rotate in sequence. When the adhesive film 4 passes between the rotating first slitting roller 30 and the second slitting roller 33, the first slitting blade 31 and the second slitting blade 32 on the first slitting roller 30 and the second slitting roller 33 will cut the adhesive film 4 into a plurality of adhesive sub-films 403. In this way, the adhesive film 4 can be cut more conveniently.

[0076] In some embodiments, please refer again to Figure 7-Figure 8The second slitting roller 33 is installed on the first support plate 1 through a gap adjustment assembly. The gap adjustment assembly is used to adjust the gap between the first slitting roller 30 and the second slitting roller 33. The gap adjustment assembly includes an adjusting roller 29 installed between the first support plate 1 and the second support plate 27. The adjusting roller 29 is connected to the second slitting roller 33. A worm gear 36 is installed on the adjusting roller 29, and a worm 35 meshing with the worm gear 36 is installed on the second support plate 27.

[0077] The worm 35 can also be connected to a handle 34. When the distance between the first slitting roller 30 and the second slitting roller 33 needs to be adjusted, the worm 35 can be driven to rotate by the handle 34. The rotation of the worm 35 then drives the turbine and the adjusting roller 29 to rotate in turn. Since the adjusting roller 29 is connected to the second slitting roller 33 through the second connecting plate 28, when the adjusting roller 29 rotates, the second slitting roller 33 will be driven to swing. When the second slitting roller 33 swings, the distance between the second slitting roller 33 and the first slitting roller 30 can be changed. In this way, it is easier to adjust the gap between the first slitting roller 30 and the second slitting roller 33, thereby making it easier to cut the adhesive film 4.

[0078] Preferably, see again Figure 8 A dust cover 37 is also installed on the second connecting plate 28 through a rotating shaft. The dust cover 37 can rotate around the rotating shaft, and the dust cover 37 can cover the second slitting roller 33.

[0079] In some embodiments, please refer again to Figure 1 The slitting device further comprises a crossbeam 6 mounted on the first support plate 1 , and a controller 3 is mounted on the crossbeam 6 .

[0080] The controller 3 is a conventional product, and the installation method, circuit connection, and working principle of the controller 3 are all known to those skilled in the art. The controller 3 can be electrically connected to the first rotating motor 10, the second rotating motor 16, the third rotating motor 40, etc., so that the first rotating motor 10, the second rotating motor 16, the third rotating motor 40, etc. can be controlled by the controller 3, thereby further improving the slitting efficiency of the film material and the winding efficiency of the film material waste of the slitting device.

[0081] The above are only various implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
