Description

Technical Field

[0001] The utility model relates to the technical field of composite current collectors, in particular to a film rewinding device. Background Art

[0002] The composite current collector film is obtained by sequentially preparing a metal bonding layer and a current collector layer in situ on the substrate by DC magnetron sputtering, and then continuing to perform annealing and crystallization treatment by program temperature control. The rewinder plays an important role in the production process of the composite current collector film.

[0003] Rewinding machines are generally used for rewinding and slitting mica tapes, paper, and films, and they play the role of cutting one in two. They are often used to slitting wide-width rolls and play an important role in subsequent slitting. They are special equipment for paper, mica tapes, and films.

[0004] When rewinding the film, a designated film rewinder is required to rewind it. However, the existing rewinder does not have a good self-driving cutting mechanism inside during use, which results in external construction workers being required to perform construction work on it when the film is cut, wasting a lot of work time of the construction workers.

[0005] Therefore, it is necessary to provide a film rewinding device to solve the above problems. Utility Model Content

[0006] In order to overcome the above shortcomings, the purpose of the utility model is to provide a film rewinding device, which can automatically rewind and cut the composite current collector film without the need for staff assistance, thereby reducing the labor intensity of the staff and improving the applicability of the rewinding device.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is: a film rewinding device, including a slitting assembly, a slitting knife horizontal distance adjustment assembly and a winding disk; the slitting assembly includes a slitting support roller, a slitting knife one and a slitting knife two, and the collector film slit by the slitting assembly is wound up by the winding disk, the slitting knife horizontal distance adjustment assembly includes a bidirectional screw rod, the slitting knife one and the slitting knife two are respectively located on the left screw rod and the right screw rod on the bidirectional screw rod, when the bidirectional screw rod is rotated, the slitting knife one and the slitting knife two can move toward or away from each other along their length direction to adjust the distance between them, the two ends of the bidirectional screw rod in the length direction are connected to the rotating adjustment assembly, and the slitting knife one and the slitting knife two can be driven by the rotating adjustment assembly to swing toward or away from the slitting support roller.

[0008] Furthermore, the slitting assembly also includes two support seats, which are respectively connected to the two ends of the slitting support roller in the length direction through support bearings, and at least one end of the two ends of the slitting support roller in the length direction extends out of the support bearing and is fixedly connected to the driving end of the support roller driving member. The two support seats support the horizontally arranged slitting support roller, and the support roller driving member can drive the slitting support roller to rotate, thereby driving the uninterrupted movement and slitting of the collector film, effectively improving the slitting efficiency of the collector film.

[0009] Furthermore, the cutter horizontal distance adjustment assembly also includes a screw drive and a guide rod parallel to the length direction of the bidirectional screw and passing through the slitting knife 1 and the slitting knife 2, and the driving end of the screw drive is connected to one end of the bidirectional screw in the length direction. The setting of the guide rod limits the circumferential rotation of the slitting knife 1 and the slitting knife 2, so that when the bidirectional screw rotates, the force driving the slitting knife 1 and the slitting knife 2 to rotate can be converted into a force driving the slitting knife 1 and the slitting knife 2 to move horizontally.

[0010] Furthermore, the invention also comprises a rewinding frame, wherein the rewinding frame comprises a slitting support and a rewinding support arranged in parallel along the length direction of the bottom plate. The slitting support is used to support and place the slitting assembly, and the rewinding support is used to support and place the rewinding reel.

[0011] Furthermore, the rotation adjustment assembly includes a rotation support frame, which includes a horizontally arranged connecting cross bar and connecting vertical rods located at both ends of the connecting cross bar and perpendicular to the connecting cross bar. The middle part of the connecting vertical rod is rotatably connected to the slitting bracket through a hinge axis extending from a hinge seat on the slitting bracket. One end of the connecting vertical rod is connected to a bidirectional screw rod through a connecting shaft seat, and the other end is hinged to a driving end of a telescopic driving member horizontally arranged on the top of the slitting bracket.

[0012] Furthermore, a heating assembly corresponding to the positions of slitting blade 1 and slitting blade 2 is arranged on the side of the connecting crossbar facing the slitting support roller. When slitting the current collector film, the heating assembly can heat slitting blade 1 and slitting blade 2 to achieve thermal slitting, thereby effectively improving the slitting speed of the current collector film.

[0013] Furthermore, a support rod penetrating the winding disk is horizontally arranged on the winding support, and at least one of the two ends of the support rod in the length direction is connected to a winding driving member to drive the support rod to rotate. The driving end of the winding driving member drives the support rod to rotate, thereby rotating the winding disk located thereon, and automatically winding the slit current collector film.

[0014] Beneficial effects of the utility model:

[0015] 1. In the utility model, the slitting assembly, the horizontal distance adjustment assembly of the cutter, the winding disk and the winding disk driving member cooperate with each other. The slitting knife 1 and the slitting knife 2 on the slitting assembly can automatically slit the composite current collector film, and the winding disk can automatically wind up the slit current collector film. No staff assistance is required during the slitting process, which can effectively reduce the labor intensity of the staff;

[0016] 2. In the utility model, the screw drive on the horizontal distance adjustment assembly of the cutter cooperates with the bidirectional screw. The screw drive drives the bidirectional screw to rotate so that the slitting knife 1 and the slitting knife 2 arranged on the bidirectional screw can move toward or away from each other, so as to adjust the distance between the slitting knife 1 and the slitting knife 2, so as to make the distance between the two meet the width requirements of the collector film slitting, and effectively improve the applicability of the rewinding device.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] See attached Figures 1 to 3As shown, a film rewinding device in this embodiment includes a slitting assembly 2, a slitting knife horizontal distance adjustment assembly 4 and a winding disk 5; the slitting assembly 2 includes a slitting support roller 21, a slitting knife 1 25 and a slitting knife 26, and the current collector film slit by the slitting assembly 2 is wound up by the winding disk 5, and the slitting support roller 21 supports the slitting knife 1 25 and the slitting knife 26. In the slitting state, the current collector film to be slit is located on the slitting support roller 21, and the cutting ends of the slitting knife 1 25 and the slitting knife 26 abut against the current collector film and slit it, which is convenient for the slitting operation; after the two cutters adjust the distance between them according to the required width, they are synchronously cut along the length direction of the current collector film, so that the subsequent winding of the winding disk 5 is convenient;

[0023] The cutter horizontal distance adjustment assembly 4 includes a bidirectional screw rod 41, and the slitting knife 1 25 and the slitting knife 2 26 are respectively located on the left screw rod and the right screw rod on the bidirectional screw rod 41. When the bidirectional screw rod 41 is rotated, the slitting knife 1 25 and the slitting knife 2 26 can move toward or away from each other along their length direction to adjust the distance between them. The slitting knife 1 25 and the slitting knife 2 26 move synchronously to adjust the distance between them, and the distance can be quickly adjusted to meet the requirements of the width of the current collector film. The adjustment process does not require manual operation and adjustment by the staff, thereby avoiding errors in the manual adjustment process and ensuring the accuracy of the slitting width of the current collector film.

[0024] The two ends of the bidirectional screw rod 41 in the length direction are connected to the rotating adjustment component 3, and the rotating adjustment component 3 can drive the slitting knife 1 25 and the slitting knife 2 26 to swing toward or away from the slitting support roller 21. During slitting, the bidirectional screw rod 41 is driven by the rotating adjustment component 3 to swing toward the direction close to the slitting support roller 21, so that the slitting ends of the slitting knife 1 25 and the slitting knife 2 26 on it are against the current collector film on the slitting support roller 21. After the slitting is completed, the slitting knife 1 25 and the slitting knife 2 26 are away from the slitting support roller 21 under the action of the rotating adjustment component 3, thereby ensuring that the feeding of the next section of the current collector film to be slitting will not be affected.

[0025] The bidirectional screw rod 41, the slitting support roller 21 and the winding disk 5 are all arranged parallel to each other to avoid affecting the winding of the current collector film after slitting.

[0026] The slitting assembly 2 also includes two support seats 23, and the two support seats 23 are respectively connected to the two ends of the slitting support roller 21 in the length direction through support bearings 24. At least one end of the two ends of the slitting support roller 21 in the length direction extends out of the support bearing 24, and is fixedly connected to the driving end of the support roller driving member 22. The two support seats 23 support the horizontally arranged slitting support roller 21, and the support roller driving member 22 can drive the slitting support roller 21 to rotate, thereby driving the uninterrupted movement and slitting of the current collector film, effectively improving the slitting efficiency of the current collector film.

[0027] The support roller driving member 22 is a driving motor, and the rotation shaft of the driving motor can drive the slitting support roller 21 to rotate. It should be noted that it is not limited to the driving motor here, and it can also be a dividing plate or other known mechanical structures that can drive the slitting support plate to rotate.

[0028] The cutter horizontal distance adjustment assembly 4 also includes a screw drive 42 and a guide rod 43 which is parallel to the length direction of the bidirectional screw 41 and passes through the slitting knife 1 25 and the slitting knife 2 26. The driving end of the screw drive 42 is connected to one end of the bidirectional screw 41 in the length direction. The setting of the guide rod 43 limits the circumferential rotation of the slitting knife 1 25 and the slitting knife 2 26, so that when the bidirectional screw 41 rotates, the force driving the slitting knife 1 25 and the slitting knife 2 26 to rotate can be converted into a force driving the slitting knife 1 25 and the slitting knife 2 26 to move horizontally. The horizontal movement of the slitting knife 1 25 and the slitting knife 2 26 along the length direction of the bidirectional screw 41 is realized, and the distance between the two slitting knives 1 25 and the slitting knife 2 26 can be automatically adjusted so that the distance meets the width requirement of the collector film to be cut.

[0029] It should be noted that the two ends of the guide rod 43 in the length direction are respectively fixed on two hinge seats 33 for connecting the bidirectional screw rod 41 .

[0030] The rewinding frame 1 includes a slitting support 11 and a rewinding support 12 arranged in parallel along the length direction of the bottom plate. The slitting support 11 is used to support and place the slitting assembly 2, and the rewinding support 12 is used to support and place the rewinding disk 5.

[0031] The rotation adjustment component 3 includes a rotation support frame 31, which includes a horizontally arranged connecting cross bar 311 and connecting vertical rods 312 located at both ends of the connecting cross bar 311 and perpendicular to it. The middle part of the connecting vertical rod 312 is rotatably connected to the slitting bracket 11 through a hinge axis extending from a hinge seat 33 on the slitting bracket 11. One end of the connecting vertical rod 312 is connected to the bidirectional screw rod 41 through a connecting shaft seat 32, and the other end is hinged to the driving end of the telescopic driving member 34 horizontally arranged on the top of the slitting bracket 11.

[0032] When slitting, it is necessary to adjust the slitting knife 1 25 and the slitting knife 26 to abut against the current collector film on the slitting support roller 21. Therefore, the driving end of the telescopic driving member 34 extends out. At this time, the end of the connecting vertical rod 312 connected to the driving end swings in the direction away from the telescopic cylinder with the hinge shaft as the fulcrum, and the other end of the connecting vertical rod 312 connected to the bidirectional screw rod 41 drives the slitting knife 1 25 and the slitting knife 26 on the bidirectional screw rod 41 to swing in the direction close to the slitting support roller 21 until the upper slitting knife 1 25 and the slitting knife 26 abut against the current collector film.

[0033] When replacing the next roll of collector film to be rewound, the driving end of the telescopic driving member 34 is retracted, and the end of the connecting vertical rod 312 connected to the bidirectional screw rod 41 swings in the direction away from the slitting support roller 21, thereby facilitating the loading of the new roll of collector film.

[0034] It should be noted that the telescopic driving member 34 here can be a telescopic cylinder, and the reciprocating swing of the connecting vertical rod 312 with the hinge axis as the fulcrum is achieved through the extension and retraction of the piston rod of the telescopic cylinder.

[0035] A heating assembly corresponding to the positions of the slitting blade 1 25 and the slitting blade 2 26 is provided on the side of the connecting crossbar 311 facing the slitting support roller 21. When slitting the current collector film, the slitting blade 1 25 and the slitting blade 2 26 can be heated by the heating assembly to achieve thermal slitting, thereby effectively improving the slitting speed of the current collector film.

[0036] A support rod 7 penetrating the winding disk 5 is horizontally arranged on the winding bracket 12, and at least one end of the two ends of the support rod 7 in the length direction is connected to a winding driving member 6 to drive the support rod 7 to rotate. The driving end of the winding driving member 6 drives the support rod 7 to rotate, thereby rotating the winding disk 5 located thereon, and automatically winding the slit current collector film. The winding driving member 6 can be a winding cylinder or a winding indexing disk, as long as the rotation of the support rod 7 can be realized.

[0037] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
