[0036] All features disclosed in this specification, and / or all steps of any methods or processes disclosed in this specification, can be combined in any combination, except combinations where at least some of the features and / or steps are mutually exclusive.

[0037] Any feature in the foregoing description, and / or shown in the accompanying drawings, claims, and / or any subsequent priority document(s), that forms no part of the prior art can be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. That is, except as required by law, no aspect of the description or drawings shall be construed as critical, essential, or required. Accordingly, the concrete embodiment described herein is illustrative only and not restrictive.

[0038] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present application will be further described below in combination with the accompanying drawings and through specific embodiments.

[0039] The winding film flattening mechanism provided in the embodiment can rotate and press against the film surface of the winding aluminum film without affecting the normal movement of the winding aluminum film. The winding aluminum film is wound on the part of the cold drum and can move on the cold drum, so that the cold drum provides cooling effect on the winding aluminum film. The winding aluminum film refers to a composite film formed after aluminum is plated on a PET (Polyethylene terephthalate) substrate.

[0040] Specifically, as shown in Figure 1 and Figure 2 , the winding film flattening mechanism comprises a support 2 and two flattening assemblies 1. The support 2 is arranged above the cold drum 3, and the support 2 is parallel to the cold drum 3. The flattening assembly 1 is arranged on the support 2 and can move along the X direction on the support 2 and rotate relative to the support 2 about the X direction. The flattening assembly 1 comprises an adjusting module 11 and a pressing wheel 12 connected with each other. The adjusting module 11 can drive the pressing wheel 12 to rotate relative to the cold drum 3 about the X direction and move along the Z direction and the Y direction. The pressing wheel 12 is located above the winding aluminum film and can rotate under the driving of the winding aluminum film. The pressing wheel 12 can rotate and press against the film surface of the winding aluminum film, so that the pressing wheel 12 can press and flatten the winding aluminum film on the cold drum 3. The X direction is parallel to the central axis of the support 2, and the Y direction and the Z direction are perpendicular to the X direction, respectively. The X direction, the Y direction and the Z direction are shown by arrows X, Y and Z in Figure 1 , respectively.

[0041] By arranging the flattening assembly 1 on the support 2, the flattening assembly 1 can move along the X direction on the support 2 and rotate around the X direction relative to the support 2, and the adjusting module 11 of the flattening assembly 1 can drive the pressing wheel 12 to rotate around the X direction relative to the cold drum 3 and move along the Z direction and the Y direction, so that the pressing wheel 12 can rotate and press against the film surface of the wound aluminum film at a suitable angle and position, thereby enabling the wound aluminum film to be pressed and fitted on the cold drum 3, avoiding the wound aluminum film from sliding along the X direction on the cold drum 3, while not affecting the normal movement of the wound aluminum film on the cold drum 3. By using the above-mentioned manner, the wound aluminum film can be rotated and pressed by the pressing wheel 12 at both ends without affecting the normal movement of the wound aluminum film, thereby preventing the wound aluminum film from wrinkling due to slipping on the cold drum 3, and ensuring that the appearance of the wound aluminum film is relatively beautiful. Moreover, since the wound aluminum film can be prevented from wrinkling, the wound aluminum film cannot be directly discarded due to the wrinkled wound aluminum film being unable to be used to make electrodes, thereby ensuring the normal use performance of the wound aluminum film. At the same time, since the flattening assembly 1 can move along the X direction on the support 2 and rotate around the X direction relative to the support 2, and the adjusting module 11 can drive the pressing wheel 12 to rotate around the X direction relative to the cold drum 3 and move along the Z direction and the Y direction, the pressing wheel 12 can be pressed against wound aluminum films of various sizes, thereby making the practicality and versatility of the entire wound film fitting and flattening mechanism better.

[0042] In this embodiment, the support 2 is fixedly arranged above the cold drum 3, that is, the support 2 remains stationary relative to the cold drum 3. In this embodiment, one support 2 is arranged, and two flattening assemblies 1 are arranged on the support 2 at intervals. The two flattening assemblies 1 are located at both ends of the wound aluminum film in the X direction. In other embodiments, two supports 2 can be arranged, and one flattening assembly 1 can be arranged on one support 2.

[0043] Further, the rotating speed of the pressing wheel 12 is the same as the moving speed of the winding aluminum film, and in the two flattening assemblies 1, the rotating direction of the pressing wheel 12 of one of the flattening assemblies 1 is parallel to the moving direction of the winding aluminum film, and the rotating direction of the pressing wheel 12 of the other flattening assembly 1 is set to be an acute angle a with the moving direction of the winding aluminum film, and the pressing force of the pressing wheel 12 parallel to the moving direction of the winding aluminum film on the winding aluminum film is greater than the pressing force of the pressing wheel 12 set to be an acute angle a with the moving direction of the winding aluminum film on the winding aluminum film. Each flattening assembly 1 comprises a pressing wheel 12, and the moving direction of the winding aluminum film specifically refers to the moving direction of the winding aluminum film on the cold drum directly below the pressing wheel, that is, the moving direction of the winding aluminum film is parallel to the Y direction, and the rotating speed of the pressing wheel 12 specifically refers to the linear speed of the bottom end surface of the pressing wheel 12 in contact with the winding aluminum film, and the rotating direction of the pressing wheel 12 specifically refers to the direction of the linear speed of the bottom end surface of the pressing wheel 12 in contact with the winding aluminum film.

[0044] By setting the rotating direction of the pressing wheel 12 of one of the two flattening assemblies 1 to be parallel to the moving direction of the winding aluminum film, the pressing wheel 12 of the flattening assembly 1 can press and fit the winding aluminum film on the cold drum 3, so that the pressing wheel 12 can slide and tension the winding aluminum film in the Y direction, avoiding the problem of slippage of the winding aluminum film on the cold drum 3. At the same time, by setting the rotating direction of the pressing wheel 12 of the other flattening assembly 1 to be an acute angle a with the moving direction of the winding aluminum film, the pressing wheel 12 of the flattening assembly 1 can provide a rotating pressing force to the winding aluminum film while providing a flattening force to the winding aluminum film in the moving direction of the winding aluminum film, so as to slide and tension the winding aluminum film in the Y direction, thereby making the flatness of the winding aluminum film better, that is, the pressing wheel 12 can have the effects of pressing and fitting and flattening the winding aluminum film. In addition, the pressing force of the pressing wheel 12 parallel to the moving direction of the winding aluminum film on the winding aluminum film is greater than the pressing force of the pressing wheel 12 set to be an acute angle a with the moving direction of the winding aluminum film on the winding aluminum film, so as to ensure the rotating pressing effect on the winding aluminum film and avoid the problem that the winding aluminum film cannot be pressed and fitted on the cold drum 3 while having the flattening effect.

[0045] Specifically, the acute angle a is 0°<a≤5°, so as to make the flattening effect of the pressing wheel 12 on the winding aluminum film better, on the one hand, to avoid the problem that the winding aluminum film cannot be pressed and fitted on the cold drum 3 due to the acute angle a being too large, and on the other hand, to avoid the problem that the winding aluminum film cannot be provided with an outward expanding flattening force due to the acute angle a being too small, and the flattening effect on the winding aluminum film cannot be ensured.

[0046] Specifically, as shown in Figure 1 and Figure 2As shown, the adjusting module 11 comprises a connecting ring 111 and an adjusting block, one end of the adjusting block is connected with the connecting ring 111, and the other end of the adjusting block is rotationally connected with the pressing wheel 12, the connecting ring 111 is sleeved on the support 2, and the connecting ring 111 can slide on the support 2 along the X direction, so that the whole flattening assembly 1 can move along the X direction on the support 2; at the same time, the connecting ring 111 can also rotate around the X direction, so that the whole flattening assembly 1 can rotate around the X direction, so that the pressing force on the flattening assembly 1 can be moved to the appropriate position and rotated to the appropriate angle and then pressed on the film surface of the wound aluminum film. Wherein, the support 2 can be a fixed roller, so that the shape of the support 2 matches the shape of the connecting ring 111, which is conducive to the sliding of the connecting ring 111 on the support 2 along the X direction and the rotation of the connecting ring 111 around the X direction. In other embodiments, the support 2 can also be other structures, which are not limited here.

[0047] It is worth noting that in other embodiments, the support 2 can also be movably arranged above the cold drum 3, so that the support 2 can slide along the X direction and rotate around the X direction, thereby driving the connecting ring 111 to slide along the X direction and rotate around the X direction through the support 2.

[0048] Further, a locking structure is arranged on the connecting ring 111; when the connecting ring 111 does not need to move, the locking structure can lock the connecting ring 111 on the support 2, so that the connecting ring 111 is fixedly arranged at any position on the support 2; when the connecting ring 111 needs to move, the locking structure is opened to release the locking between the connecting ring 111 and the support 2, so that the connecting ring 111 can slide on the support 2 along the X direction and rotate around the X direction. Wherein, the locking structure specifically comprises a locking screw, a locking hole and a plurality of threaded holes, the locking hole is arranged on the connecting ring 111, and the plurality of threaded holes are arranged on the support 2, the locking screw is inserted into the locking hole and any threaded hole in sequence, thereby the connecting ring 111 can be locked and fixed at any position on the support 2.

[0049] Specifically, the support 2 can be fixedly arranged on the support frame, and a linear cylinder is arranged on the support frame, that is, the fixed end of the linear cylinder is arranged on the support frame, and the driving end of the linear cylinder is drivingly connected with the connecting ring 111; first, the locking screw is taken out of the locking hole and the threaded hole, and then the linear cylinder drives the connecting ring 111 to move on the support 2 along the X direction, so that the whole flattening assembly 1 can move along the X direction on the support 2; when the linear cylinder is not working, the connecting ring 111 stops on the support 2 and is fixed at this position, that is, the connecting ring 111 will not move on the support 2 without the external force driving of the linear cylinder; at the same time, the locking screw is inserted into the locking hole and any threaded hole in sequence, which further ensures the stability of the arrangement of the connecting ring 111 on the support 2.

[0050] Further, the connecting plate is arranged at the driving end of the linear cylinder, and the rotary cylinder is arranged on the connecting plate, i.e. the fixed end of the rotary cylinder is arranged on the connecting plate, so that the linear cylinder can drive the rotary cylinder to move synchronously while the connecting ring 111 moves along the X direction; and the driving end of the rotary cylinder is drivingly connected with the transverse slide plate 112 of the adjusting block, and the transverse slide plate 112 is fixedly connected with the connecting ring 111, so that the transverse slide plate 112 and the connecting ring 111 can be driven by the rotary cylinder to rotate around the X direction relative to the support 2, so that the whole pressing assembly 1 can rotate around the X direction; when the rotary cylinder is not working, the transverse slide plate 112 and the connecting ring 111 are stopped on the support 2 and fixed at the position, i.e. the transverse slide plate 112 and the connecting ring 111 will not rotate around the X direction relative to the support 2 without the external force driving of the rotary cylinder, and the locking screw is sequentially inserted into the locking hole and any threaded hole, further ensuring the stability of the arrangement of the connecting ring 111 on the support 2.

[0051] Further, as shown in Figure 1 and Figure 2 , the adjusting block comprises the transverse slide plate 112, the angle rotating plate 113 and the vertical slide plate 114; wherein the end of the transverse slide plate 112 not fixedly connected with the connecting ring 111 is sleeved with the transverse slide block 115 which can slide along the Y direction on the transverse slide plate 112; the angle rotating plate 113 is connected to the transverse slide block 115 and can rotate relative to the transverse slide block 115; one end of the vertical slide plate 114 is connected to the angle rotating plate 113, and the other end of the vertical slide plate 114 is rotationally connected with the pressing wheel 12, and the vertical slide plate 114 can slide along the Z direction relative to the angle rotating plate 113, so that the adjusting module 11 can drive the pressing wheel 12 to move along the Y direction, rotate around the X direction relative to the cold drum 3 and move along the Z direction, so as to further adjust the position and angle of the pressing wheel 12 relative to the cold drum 3.

[0052] It is worth noting that the transverse slide block 115 can be fixed at any position along the Y direction on the transverse slide plate 112, i.e. the transverse slide block 115 will not slide along the Y direction on the transverse slide plate 112 without external force driving, and the external force driving of the transverse slide block 115 can be manual driving or motor driving; and the above-mentioned locking structure can also be arranged between the transverse slide block 115 and the transverse slide plate 112, i.e. the locking hole is arranged on the transverse slide block 115, and the plurality of threaded holes are arranged on the transverse slide plate 112, so that the transverse slide block 115 can be locked on the transverse slide plate 112 when the transverse slide block 115 slides to the preset position, further ensuring the stability of the arrangement of the transverse slide block 115 on the transverse slide plate 112.

[0053] Specifically, as shown in Figure 2As shown, a rotating block is arranged on one of the lateral sliding block 115 and the angle rotating plate 113, and an arc-shaped sliding slot 116 is arranged on the other one, and the rotating block can slide in the arc-shaped sliding slot 116 to enable the pressing wheel 12 to rotate around the X direction. In this embodiment, the arc-shaped sliding slot 116 is arranged on the angle rotating plate 113, and the rotating block is arranged on the lateral sliding block 115.

[0054] It is worth noting that the rotating block can be fixed at any position around the X direction in the arc-shaped sliding slot 116, i.e. the rotating block will not rotate around the X direction in the arc-shaped sliding slot 116 without external force driving, and the external force driving of the rotating block can be manual driving or motor driving; and the above-mentioned locking structure can also be arranged between the angle rotating plate 113 and the lateral sliding block 115, i.e. the locking hole is arranged on the angle rotating plate 113, and the plurality of threaded holes are arranged on the lateral sliding block 115, so as to lock the angle rotating plate 113 on the lateral sliding block 115 when the angle rotating plate 113 rotates to the preset position, further ensuring the setting stability of the angle rotating plate 113 on the lateral sliding block 115. Specifically, as shown in Figure 2 As shown, a vertical sliding block is arranged on one of the angle rotating plate 113 and the vertical sliding plate 114, and a straight sliding slot 117 extending along the Z direction is arranged on the other one, and the vertical sliding block can slide in the straight sliding slot 117. In this embodiment, the straight sliding slot 117 is arranged on the vertical sliding plate 114, and the vertical sliding block is arranged on the angle rotating plate 113.

[0055] It is worth noting that the vertical sliding block can be fixed at any position along the Z direction in the straight sliding slot 117, i.e. the vertical sliding block will not slide along the Z direction in the straight sliding slot 117 without external force driving, and the external force driving of the vertical sliding block can be manual driving or motor driving; and the above-mentioned locking structure can also be arranged between the vertical sliding plate 114 and the angle rotating plate 113, i.e. the locking hole is arranged on the angle rotating plate 113, and the plurality of threaded holes are arranged on the vertical sliding plate 114, so as to lock the vertical sliding plate 114 on the angle rotating plate 113 when the vertical sliding plate 114 slides to the preset position, further ensuring the setting stability of the vertical sliding plate 114 on the angle rotating plate 113. Rotation

[0056] Further, as shown in Figure 1 and Figure 2As shown, a square plate 14 is also slidably arranged on the vertical slide plate 114, and the square plate 14 can slide along the Z axis relative to the vertical slide plate 114 and stop at any position; and the pressing assembly 1 further comprises a push-pull force gauge 13, which comprises a housing 131, an output shaft 132, an elastic member, and a measuring member, the housing 131 is fixedly arranged on the square plate 14, one end of the elastic member is fixedly arranged on the inner side of the housing 131, the other end of the elastic member is fixedly connected with the output shaft 132, the output shaft 132 can be connected to the pressing wheel 12, and when the pressing wheel 12 is pressed on the wound aluminum film, the elastic member is in a compressed state, so that the elastic force of the elastic member can act on the pressing wheel 12, so that the pressing wheel 12 can press the wound aluminum film; the measuring member is arranged on the inner side of the housing 131 for detecting the pressing force of the pressing wheel 12 pressed on the wound aluminum film. The measuring member in the embodiment is a common measuring structure in the existing push-pull gauge, and the specific measuring principle will not be described in detail here.

[0057] Specifically, when the measuring member detects that the pressing force is too large, the square plate 14 is slid upward along the Z axis relative to the vertical slide plate 114 to an appropriate position, so as to reduce the elastic deformation degree of the elastic member, thereby reducing the elastic force of the elastic member, so that the force of the elastic member acting on the pressing wheel 12 becomes smaller, thereby reducing the pressing force of the pressing wheel 12 pressed on the wound aluminum film; when the measuring member detects that the pressing force is too small, the square plate 14 is slid downward along the Z axis relative to the vertical slide plate 114 to an appropriate position, so as to increase the elastic deformation degree of the elastic member, thereby increasing the elastic force of the elastic member, so that the force of the elastic member acting on the pressing wheel 12 becomes larger, thereby increasing the pressing force of the pressing wheel 12 pressed on the wound aluminum film.

[0058] By adjusting the elastic force of the elastic member, the pressing force of the pressing wheel 12 can be adjusted, so as to avoid the problem that the pressing force of the pressing wheel 12 on the wound aluminum film is too large to make the wound aluminum film move on the cold drum 3, and at the same time avoid the problem that the pressing force of the pressing wheel 12 on the wound aluminum film is too small to ensure the pressing effect of the pressing wheel 12 on the wound aluminum film, thereby causing the problem of slipping of the wound aluminum film on the cold drum 3. In the embodiment, the elastic member can be a compression spring.

[0059] Specifically, as shown in FIG. 6, the square plate 14 is slid along the Z axis relative to the vertical slide plate 114 to an appropriate position, so as to adjust the elastic force of the elastic member, thereby adjusting the pressing force of the pressing wheel 12 on the wound aluminum film. Figure 2As shown, the flattening assembly 1 further comprises a mounting plate 19, a fixing nut 191 and a locking bolt; the mounting plate 19 is detachably arranged on the vertical sliding plate 114, and the fixing nut 191 can threadedly connect the square plate 14 to the mounting plate 19; a first mounting hole is arranged on the mounting plate 19, and a plurality of second mounting holes are further arranged on the vertical sliding plate 114; when the square plate 14 is slid along the Z-axis to a suitable position on the vertical sliding plate 114, the locking bolt is sequentially inserted into the second mounting hole and the first mounting hole, so that the mounting plate 19 can be fixedly arranged on the vertical sliding plate 114, avoiding the mounting plate 19 and the square plate 14 from continuously moving along the Z-axis, and ensuring the stability of the arrangement of the square plate 14 on the vertical sliding plate 114.

[0060] Specifically, as shown in the figure, Figure 2 one of the vertical sliding plate 114 and the square plate 14 is provided with a vertical sliding block, and the other is provided with a vertical sliding groove 15 extending in the Z direction, the vertical sliding block can slide in the vertical sliding groove 15 to provide guidance and stability for the sliding of the square plate 14 on the vertical sliding plate 114. In this embodiment, the vertical sliding block is arranged on the vertical sliding plate 114, and the vertical sliding groove 15 is arranged on the square plate 14.

[0061] Further, as shown in the figure, Figure 2 the flattening assembly 1 further comprises an intermediate plate 16, a guide rod 17 and a connecting seat 18; the bottom end of the output shaft 132 is fixedly connected to the intermediate plate 16, the intermediate plate 16 is located on the inner side of the vertical sliding plate 114, the guide rod 17 slides through the vertical sliding plate 114, and the two ends of the guide rod 17 are fixedly connected to the intermediate plate 16 and the connecting seat 18 respectively, the connecting seat 18 is located below the vertical sliding plate 114, and the pressing wheel 12 is rotatably arranged in the connecting seat 18.

[0062] Specifically, when the elastic force of the elastic member acts on the output shaft 132, the output shaft 132 can drive the intermediate plate 16, the guide rod 17 and the connecting seat 18 to move downward, so that the pressing wheel 12 can press on the wound aluminum film; and since the guide rod 17 can be limited to slide in the vertical sliding plate 114, the guide rod 17 can provide a guiding effect for the pressing of the pressing wheel 12, ensuring that the pressing wheel 12 will not deviate. In this embodiment, the guide rod 17 is provided with two. The number of guide rods 17 is not limited.

[0063] Further, the pressing wheel 12 is made of polyurethane material, so as to avoid the problem of abrasion or damage of the wound aluminum film during the rotation and pressing of the pressing wheel 12. Among them, two pressing wheels 12 can also be replaced by one pressing roller, so that the pressing area between the pressing roller and the wound aluminum film is larger, thereby better avoiding the problem of slipping of the wound aluminum film on the cold drum 3.

[0064] The specific working process of the flattening mechanism of the winding film in the embodiment is as follows:

[0065] Firstly, according to the specific size of the winding aluminum film on the cold drum 3, the actual position and angle of the pressing wheel 12 are adjusted, the connecting ring 111 is moved along the X direction on the support 2 and rotated around the X direction relative to the support 2, the transverse sliding block 115 is slid along the Y direction on the transverse sliding plate 112, the rotating block is arc-shaped slid along the X direction in the arc-shaped sliding groove 116, and the vertical sliding block is slid along the Z direction in the straight sliding groove 117, so that the position and angle of the pressing wheel 12 relative to the winding aluminum film are more appropriate; then the cold drum 3 and the winding aluminum film start to move, so that the winding aluminum film can drive the pressing wheel 12 to rotate, so that the pressing wheel 12 can be pressed and rotated to the winding aluminum film, and then the winding aluminum film is pressed and attached to the cold drum 3, so as to prevent the winding aluminum film from slipping on the cold drum 3.

[0066] That is to say, at this time, the rotating direction of one of the two pressing wheels 12 is parallel to the moving direction of the winding aluminum film, so that the pressing wheel 12 can provide a rotating pressing effect on the winding aluminum film; the rotating direction of the other pressing wheel 12 is arranged at an acute angle α with the moving direction of the winding aluminum film, so that the pressing wheel 12 can provide a rotating pressing and outward flattening effect on the winding aluminum film.

[0067] The flattening mechanism of the winding film in the embodiment can not only avoid the problem of the winding aluminum film slipping on the cold drum 3, but also can flatten the winding aluminum film outward, so as to ensure the flatness of the winding aluminum film, so that the winding aluminum film will not wrinkle, and the appearance of the winding aluminum film is more beautiful.

[0068] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the description should not be understood as limiting the present application.
