Description

Technical Field

[0001] The utility model relates to the technical field of composite film production, and particularly relates to a winding device. Background Art

[0002] In recent years, with the development of the lithium battery industry and the increasingly fierce market competition, the composite films required for lithium battery production have become thinner and thinner. At present, in the process of ultra-thin composite film production, a winding device is usually used to wind the composite film.

[0003] The existing winding device generally includes a frame and a winding mechanism arranged on the frame. The winding mechanism includes a first rotating shaft, a second rotating shaft, a first chuck, a second chuck and a winding driving assembly. The first rotating shaft and the second rotating shaft are arranged oppositely. A first chuck is provided at one end of the first rotating shaft close to the second rotating shaft, and a second chuck is provided at one end of the second rotating shaft close to the first rotating shaft. The first chuck and the second chuck are arranged oppositely. The winding driving assembly is used to drive the first rotating shaft to rotate. When winding the composite film, the two ends of the winding drum are respectively inserted into the first chuck and the second chuck. After the composite film is wound around the winding drum, the first rotating shaft is driven to rotate by the winding driving assembly, so as to drive the first chuck, the winding drum, the second chuck and the second rotating shaft to rotate, thus realizing the winding of the composite film.

[0004] In the above winding device, the winding of the composite film mainly relies on the winding tension to pull the composite film to wind on the winding drum. When using the winding tension to pull the composite film to wind on the winding drum, the pressure between the layers of the composite film is often inconsistent, and it is impossible to ensure that the tightness of each layer of the composite film is the same, resulting in wrinkles, looseness, etc. of the composite film, and air is easily introduced between the layers of the composite film, resulting in bubbles, etc. in the composite film, thus affecting the quality of the composite film.

[0055] The rubber pressing roller 36 is arranged in parallel with the steel roller 33, and the steel roller 33 is located between the rubber pressing roller 36 and the first rotating shaft 21 and the second rotating shaft 22. Both ends of the rubber pressing roller 36 are rotatably arranged on the inner sides of two mounting blocks 37 through two rubber pressing roller bearing seats 361.

The rubber pressing roller 36 is used to press the composite film 100 against the steel roller 33 to cut off the tension of the composite film 100.

[0057] In this embodiment, the rubber pressing roller driving assembly includes two rubber pressing roller cylinders 38. The two rubber pressing roller cylinders 38 are respectively arranged on the inner sides of the first mounting plate 31 and the second mounting plate 32 through a cylinder seat. The two rubber pressing roller cylinders 38 are respectively located on the sides of the two mounting blocks 37 away from the steel roller 33, for example, on the left sides of the two mounting blocks 37. The ends of the output shafts of the two rubber pressing roller cylinders 38 are respectively connected to the ends of the two mounting blocks 37 away from the steel roller 33. By the extension or retraction of the output shafts of the two rubber pressing roller cylinders 38, the two mounting blocks 37 can be respectively driven to move towards or away from the steel roller 33 through the two rubber pressing roller cylinders 38.

[0058] When the first mounting plate 31 and the second mounting plate 32 move towards or away from the first rotating shaft 21 and the second rotating shaft 22, the rubber pressing roller 36, the two mounting blocks 37 and the two rubber pressing roller cylinders 38 can be driven to move towards or away from the first rotating shaft 21 and the second rotating shaft 22 through the first mounting plate 31 and the second mounting plate 32.

[0059] One end and the other end of the fixed roller 40 are respectively arranged on the frame 10 through the first adjustment assembly and the second adjustment assembly. The fixed roller 40 is used to support the composite film 100. Specifically, one end of the fixed roller 40 is arranged inside the first side plate 10a through the first adjustment assembly, and the other end of the fixed roller 40 is arranged inside the second side plate 10b through the second adjustment assembly. The first adjustment assembly and the second adjustment assembly are arranged opposite to each other front and back. The first adjustment assembly is used to adjust the position of one end of the fixed roller 40 in the height direction, and the second adjustment assembly is used to adjust the position of the other end of the fixed roller 40 in the height direction. By adjusting the positions of one end and the other end of the fixed roller 40 in the height direction, the levelness of the fixed roller 40 can be adjusted. The fixed roller 40 is located above the steel roller 33 and the rubber pressing roller 36, and is located on the side of the steel roller 33 away from the first rotating shaft 21 and the second rotating shaft 22, for example, on the left side of the steel roller 33. The fixed roller 40 is close to the two extension plates 14 and is located above the output shafts of the two flat push cylinders 35. One end of the first mounting plate 31 away from the first rotating shaft 21 and one end of the second mounting plate 32 away from the second rotating shaft 22 are respectively provided with a first avoidance position 317 and a second avoidance position 327 for avoiding the fixed roller 40. The first avoidance position 317 and the second avoidance position 327 are respectively located above the output shafts of the two flat push cylinders 35.

[0060] Combined Figure 10 As shown, both the first adjustment assembly and the second adjustment assembly include a connecting plate 421 (see Figure 3 ), an adjustment plate 42, an upper support block 43a, a lower support block 43b, a screw 44, and a rotating head 45. Figure 10The second adjusting component in it only shows the adjusting plate 42. Two first supports 15 are respectively provided on the inner sides of the first side plate 10a and the second side plate 10b. The connecting plates 421 of the first adjusting component and the connecting plates 421 of the second adjusting component are respectively arranged on the inner sides of the two first supports 15. One end and the other end of the fixed roller 40 are respectively rotatably arranged on the inner side of the adjusting plate 42 of the first adjusting component and the inner side of the adjusting plate 42 of the second adjusting component through two fixed roller bearing seats 41. The upper support block 43a and the lower support block 43b are both arranged on the inner side of the connecting plate 421 and are arranged opposite to each other up and down. The adjusting plate 42 is located between the upper support block 43a and the lower support block 43b. The tail end of the screw rod 44 passes through the first hole position of the upper support block 43a, the screw hole of the adjusting plate 42 and is arranged in the second hole position of the lower support block 43b. The screw rod 44 can rotate relative to the upper support block 43a and the lower support block 43b. The screw rod 44 is in threaded cooperation with the screw hole of the adjusting plate 42. The head of the screw rod 44 is provided with a rotating head 45. By rotating the rotating head 45, the screw rod 44 can be driven to rotate relative to the upper support block 43a and the lower support block 43b, so that the adjusting plate 42 can be driven to move up and down. By the up and down movement of the adjusting plate 42 of the first adjusting component and the adjusting plate 42 of the second adjusting component, one end and the other end of the fixed roller 40 can be driven to move up and down, and thus the position of one end and the other end of the fixed roller 40 in the height direction can be adjusted, so that the levelness of the fixed roller 40 can be adjusted. By adjusting the levelness of the fixed roller 40, the situation that the composite film 100 runs off can be avoided. For example, when one end of the fixed roller 40 tilts upward, by rotating the rotating head 45 of the first adjusting component, the screw rod 44 of the first adjusting component can be driven to rotate. The rotation of the screw rod 44 of the first adjusting component can drive the adjusting plate 42 of the first adjusting component to move downward, so that one end of the fixed roller 40 can be driven to move downward until the fixed roller 40 is in a horizontal state, thus realizing the adjustment of the levelness of the fixed roller 40. When one end of the fixed roller 40 tilts downward, the opposite operation can be performed according to the above steps. The adjustment method of the other end of the fixed roller is the same as that of one end of the fixed roller.

[0061] The pressing belt mechanism 50 includes a mounting member 51, two pressing blocks 52 and a pressing belt driving component. The mounting member 51 is located on one side of the fixed roller 40 and is perpendicularly arranged with respect to the fixed roller 40. In this embodiment, the mounting member 51 is located in the upper right of the fixed roller 40. Both of the two pressing blocks 52 are located between the fixed roller 40 and the mounting member 51. The two pressing blocks 52 are spaced apart on the side of the mounting member 51 close to the fixed roller 40. Both of the two pressing blocks 52 are perpendicularly arranged with respect to the fixed roller 40. In actual application, the two pressing blocks 52 respectively correspond to both sides in the length direction of the composite film 100. The two pressing blocks 52 are respectively used to press both sides in the length direction of the composite film 100 onto the fixed roller 40 to avoid the situation that the composite film 100 runs off and ensure that the composite film 100 is wound neatly.

[0062] The belt pressing drive assembly is used to drive the mounting member 51 to move towards or away from the fixed roller 40, so as to drive the two pressing blocks 52 to move towards or away from the fixed roller 40. By moving the two pressing blocks 52 towards the fixed roller 40, the two sides of the composite film 100 in the length direction can be respectively pressed against the fixed roller 40 by the two pressing blocks 52.

[0063] In this embodiment, the belt pressing drive assembly includes two belt pressing cylinders 53, and the belt pressing cylinders 53 are inclined upwards. Two first cylinder mounting plates 532 are respectively arranged on the inner sides of the two first supports 15, and the two first cylinder mounting plates 532 are respectively located on the right sides of the connecting plates 421 of the first adjusting assembly and the connecting plates 421 of the second adjusting assembly. Two second cylinder mounting plates 531 are respectively arranged on the inner sides of the two first cylinder mounting plates 532. The second cylinder mounting plates 531 are L-shaped, and the second cylinder mounting plates 431 are inclined downwards. The two belt pressing cylinders 53 are respectively arranged at the tops of the two second cylinder mounting plates 531, and the ends of the output shafts of the two belt pressing cylinders 53 respectively pass through the through holes of the corresponding second cylinder mounting plates 531 and are respectively connected to the side of the mounting member 51 away from the fixed roller 40. By the extension or retraction of the output shafts of the two belt pressing cylinders 53, the belt pressing drive assembly can drive the mounting member 51 to move towards or away from the fixed roller 40 through the two belt pressing cylinders 53.

[0064] The guide roller 60 is arranged on the frame 10, and the guide roller 60 is used to support the composite film 100. Specifically, two second supports 141 are respectively arranged on the inner sides of the two extension plates 14, two guide roller mounting plates are respectively arranged on the inner sides of the two second supports 141, and the two ends of the guide roller 60 are respectively rotatably arranged on the inner sides of the two guide roller mounting plates through two guide roller bearing seats 61. The guide roller 60 is located above the two flat push cylinders 35.

[0065] With the above structure, during actual application, first, two moving cylinders 262 are used to drive the first rotating shaft 21 and the first chuck 23 to move away from the second rotating shaft 22, and the second winding motor 271 and the second speed reducer 272 are used to drive the second rotating shaft 22 and the second chuck 24 to move away from the first rotating shaft 21, so that the distance between the first chuck 23 and the second chuck 24 is greater than the length of the winding reel. Then, one end of the winding reel is inserted into the first chuck 23. Next, two moving cylinders 262 are used to drive the first rotating shaft 21 and the first chuck 23 to move towards the second rotating shaft 22 to the initial position, and the second winding motor 271 and the second speed reducer 272 are used to drive the second rotating shaft 22 and the second chuck 24 to move towards the first rotating shaft 21 to the initial position. During the movement of the first chuck 23 and the second chuck 24, the first chuck 23 can drive the other end of the winding reel to be inserted into the second chuck 24. After the composite film 100 bypasses above the guide roller 60, above the fixed roller 40, below the rubber pressing roller 36, passes between the rubber pressing roller 36 and the steel roller 33, above the steel roller 33 in sequence and is wound around the winding reel, the first winding motor 251 and the first speed reducer 252 are used to drive the first rotating shaft 21 to rotate counterclockwise, so as to drive the first chuck 23 and the winding reel to rotate counterclockwise, and further drive the second chuck 24 and the second rotating shaft 22 to rotate counterclockwise, thereby realizing the winding of the composite film 100. When the composite film 100 bypasses above the fixed roller 40, the output shafts of the two pressing belt cylinders 53 extend, so as to drive the mounting member 51 to move towards the fixed roller 40, and drive the two pressing blocks 52 to move towards the fixed roller 40. In this way, the two pressing blocks 52 can press the two sides of the composite film 100 in the length direction against the fixed roller 40 respectively, so as to prevent the composite film 100 from running off. During the winding of the composite film 100, first, the output shafts of the two rubber pressing roller cylinders 38 extend, so that the two rubber pressing roller cylinders 38 can drive the two mounting blocks 37 to move towards the steel roller 33 respectively, and drive the rubber pressing roller 36 to move towards the steel roller 33. In this way, the composite film 100 can be pressed against the steel roller 33 by the rubber pressing roller 36, so as to realize the isolation of the tension of the composite film 100. Then, the output shafts of the two flat push cylinders 35 extend, so that the two flat push cylinders 35 can drive the first mounting plate 31 and the second mounting plate 32 to move towards the first rotating shaft 21 and the second rotating shaft 22 respectively, and drive the steel roller 33 to move towards the first rotating shaft 21 and the second rotating shaft 22, so that the steel roller 33 can press the composite film 100 on the winding reel. At the same time, the steel roller driving motor 341 is used to drive the steel roller 33 to rotate clockwise.

[0066] As the diameter of the composite film 100 on the winding reel continuously increases, the output shafts of the two flat push cylinders 35 retract accordingly according to the increase in the diameter of the composite film 100, so as to drive the first mounting plate 31 and the second mounting plate 32 to move a corresponding distance away from the first rotating shaft 21 and the second rotating shaft 22 respectively, thereby driving the steel roller 33 to move a corresponding distance away from the first rotating shaft 21 and the second rotating shaft 22. By doing so, the pressure exerted by the steel roller 33 on the composite film 100 can be kept consistent all the time, so that the rotating steel roller 33 always keeps the composite film 100 tightly pressed during the winding process, so that the pressure between the layers of the composite film 100 is consistent, ensuring that the tightness of each layer of the composite film 100 is consistent, thus avoiding situations such as wrinkling and slack of the composite film 100, and preventing air from entering between the layers of the composite film 100, thereby avoiding situations such as bubbles in the composite film 100 and ensuring the quality of the composite film 100. By isolating the tension of the composite film 100, when the steel roller 33 presses the composite film 100 on the winding reel, the situation of tensile deformation of the composite film 100 can be avoided.

[0067] After winding is completed, the two moving cylinders 262 drive the first rotating shaft 21 and the first chuck 23 to move away from the second rotating shaft 22, and the second winding motor 271 and the second speed reducer 272 drive the second rotating shaft 22 and the second chuck 24 to move away from the first rotating shaft 21, so that both ends of the winding reel are separated from the first chuck 23 and the second chuck 24 respectively, and thus the winding reel and the composite film 100 can be removed from the first chuck 23 and the second chuck 24.

[0068] In the present utility model, through the set flat push steel roller mechanism 30, the flat push steel roller mechanism 30 includes a first mounting plate 31, a second mounting plate 32, a steel roller 33, a steel roller driving component, a flat push driving component, a rubber pressing roller 36 and a rubber pressing roller driving component. During the winding process of the composite film 100, the rotating steel roller 33 always keeps the composite film 100 tightly pressed, so that the pressure between the layers of the composite film 100 is consistent, ensuring that the tightness of each layer of the composite film 100 is consistent, thus avoiding situations such as wrinkling and slack of the composite film 100, and preventing air from entering between the layers of the composite film 100, thereby avoiding situations such as bubbles in the composite film 100 and ensuring the quality of the composite film 100. The composite film 100 can be tightly pressed on the steel roller 33 through the rubber pressing roller 36 to isolate the tension of the composite film 100.

One ends of the two swing arms 73 are respectively rotatably sleeved on the outer periphery of the rotating shaft 71, and the pressure roller 72 is rotatably arranged between the other ends of the two swing arms 73. The two swing arms 73 can rotate around the axis of the rotating shaft 71, so as to drive the pressure roller 72 to rotate around the axis of the rotating shaft 71, so that the pressure roller 72 approaches or moves away from the first rotating shaft 21, the first chuck 23, the second rotating shaft 22 and the second chuck 24. The pressure roller 72 is used to press the composite film 100. In this embodiment, the distance between the connection line between the axes of the first rotating shaft 21 and the second rotating shaft 22 and the axis of the rotating shaft 71 is equal to the distance between the axis of the rotating shaft 71 and the axis of the pressure roller 72, that is, the center of the connection line between the axes of the first rotating shaft 21 and the second rotating shaft 22 is located on the rotation path of the pressure roller 72.

[0074] In this embodiment, a first swing arm through hole is provided at one end of the swing arm 73. One end of the swing arm 73 is rotatably sleeved on the outer periphery of the rotating shaft 71 through the first swing arm through hole.

[0075] The swing arm driving assembly is used to drive the two swing arms 73 to rotate around the axis of the rotating shaft 71.

[0076] The swing arm driving assembly includes two swing arm cylinders 74 arranged front and rear relative to each other. The two swing arm cylinders 74 are respectively arranged on one side close to each other of the two support seats 19. The ends of the output shafts of the two swing arm cylinders 74 are respectively rotatably connected to one side far away from each other of the two swing arms 73. By the extension or retraction of the output shafts of the two swing arm cylinders 74, the two swing arm cylinders 74 can respectively drive the two swing arms 73 to rotate around the axis of the rotating shaft 71. The support seats 19 and the swing arm cylinders 74 are both arranged obliquely downward.

[0077] In this embodiment, two swing arm cylinder plates 741 are respectively arranged on one side close to each other of the two support seats 19. The two swing arm cylinders 74 are respectively arranged on one side far away from the corresponding support seats 19 of the two swing arm cylinder plates 741 through two swing arm support members 742. The arranged swing arm cylinder plates 741 and swing arm support members 742 play a role in installing and supporting the corresponding swing arm cylinders 74.

[0078] In this embodiment, two swing arm mounting plates 732 are respectively arranged on one side far away from each other of the two swing arms 73. The swing arm mounting plates 732 are close to one end of the corresponding swing arms 73. Two swing arm mounting members 731 are respectively arranged on one side far away from the corresponding swing arms 73 of the two swing arm mounting plates 732. The ends of the output shafts of the two swing arm cylinders 74 are respectively connected with two spherical eye joints 744. The spherical eye joints 744 are of existing structures. The ends of the two spherical eye joints 744 are respectively rotatably sleeved on the outer peripheries of the ends of the two swing arm mounting members 731. Thus, the ends of the output shafts of the two swing arm cylinders 74 are respectively rotatably connected to one side far away from each other of the two swing arms 73 through the two spherical eye joints 744, the two swing arm mounting members 731, and the two swing arm mounting plates 732. The bearings inside the ends of the spherical eye joints 744 can provide rotational support for the spherical eye joints 744. The two swing arm cylinders 74 can respectively drive the two swing arms 73 to rotate around the axis of the rotating shaft 71 through the two spherical eye joints 744, the two swing arm mounting members 731, and the two swing arm mounting plates 732.

[0079] With the above structure, in actual application, in the initial state, the two swing arms 73 are both in a horizontal state, as Figure 13As shown in the figure, first, two moving cylinders 262 are used to drive the first rotating shaft 21 and the first chuck 23 to move away from the second rotating shaft 22, and the second winding motor 271 and the second speed reducer 272 are used to drive the second rotating shaft 22 and the second chuck 24 to move away from the first rotating shaft 21, so that the distance between the first chuck 23 and the second chuck 24 is greater than the length of the winding reel. Then, one end of the winding reel is inserted into the first chuck 23. Then, two moving cylinders 262 are used to drive the first rotating shaft 21 and the first chuck 23 to move towards the second rotating shaft 22 to the initial position, and the second winding motor 271 and the second speed reducer 272 are used to drive the second rotating shaft 22 and the second chuck 24 to move towards the first rotating shaft 21 to the initial position. During the movement of the first chuck 23 and the second chuck 24, the first chuck 23 can drive the other end of the winding reel to be inserted into the second chuck 24. After the composite film 100 bypasses above the guide roller 60, above the fixed roller 40, passes between the rubber pressing roller 36 and the steel roller 33, and below the steel roller 33 in sequence and is wound around the winding reel, the first winding motor 251 and the first speed reducer 252 are used to drive the first rotating shaft 21 to rotate counterclockwise, so as to drive the first chuck 23 and the winding reel to rotate counterclockwise, and further drive the second chuck 24 and the second rotating shaft 22 to rotate counterclockwise, so as to realize winding of the composite film 100. During the winding of the composite film 100, first, the output shafts of two rubber pressing roller cylinders 38 extend, so as to drive the two mounting blocks 37 to move towards the steel roller 33 respectively, and drive the rubber pressing roller 36 to move towards the steel roller 33, so that the composite film 100 can be pressed against the steel roller 33 by the rubber pressing roller 36, thus realizing the interruption of the tension of the composite film 100. Then, the output shafts of two flat push cylinders 35 extend, so as to drive the first mounting plate 31 and the second mounting plate 32 to move towards the first rotating shaft 21 and the second rotating shaft 22 respectively, and drive the steel roller 33 to move towards the first rotating shaft 21 and the second rotating shaft 22, so that the steel roller 33 can press the composite film 100 on the winding reel. At the same time, the steel roller driving motor 341 is used to drive the steel roller 33 to rotate clockwise, and the output shafts of two swing arm cylinders 74 extend, so as to drive the two swing arms 73 to rotate clockwise around the axis of the rotating shaft 71 respectively, and further drive the pressing roller 72 to rotate clockwise around the axis of the rotating shaft 71, so that the pressing roller 72 can press the composite film 100 on the winding reel.

[0080] As the diameter of the composite film 100 on the winding reel continuously increases, the output shafts of the two flat push cylinders 35 retract accordingly according to the increase in the diameter of the composite film 100, so as to drive the first mounting plate 31 and the second mounting plate 32 to move a corresponding distance away from the first rotating shaft 21 and the second rotating shaft 22 respectively, thereby driving the steel roller 33 to move a corresponding distance away from the first rotating shaft 21 and the second rotating shaft 22. At the same time, the output shafts of the two swing arm cylinders 74 retract accordingly according to the increase in the diameter of the composite film 100, so as to drive the two swing arms 73 to rotate a corresponding angle counterclockwise around the axis of the rotating shaft 71 respectively, and further drive the pressure roller 72 to rotate a corresponding angle counterclockwise around the axis of the rotating shaft 71. By doing so, the pressure exerted by the steel roller 33 on the composite film 100 can always be kept consistent, and the pressure exerted by the pressure roller 72 on the composite film 100 can always be kept consistent, so that the steel roller 33 and the pressure roller 72 always keep the composite film 100 tightly pressed during the winding process. In this way, the pressure between the layers of the composite film 100 can be made consistent, and the tightness of each layer of the composite film 100 can be ensured to be consistent, thereby avoiding situations such as wrinkling and slackening of the composite film 100, and preventing air from entering between the layers of the composite film 100, thus avoiding situations such as bubbles in the composite film 100 and ensuring the quality of the composite film 100. By isolating the tension of the composite film 100, when the steel roller 33 tightly presses the composite film 100 on the winding reel, the situation of tensile deformation of the composite film 100 can be avoided.

[0081] After winding is completed, the two moving cylinders 262 drive the first rotating shaft 21 and the first chuck 23 to move away from the second rotating shaft 22, and the second winding motor 271 and the second speed reducer 272 drive the second rotating shaft 22 and the second chuck 24 to move away from the first rotating shaft 21, so that both ends of the winding reel are separated from the first chuck 23 and the second chuck 24 respectively. In this way, the winding reel and the composite film 100 can be removed from the first chuck 23 and the second chuck 24.

[0082] This embodiment can achieve the same technical effects as the first embodiment. In this embodiment, through the swing arm pressure roller mechanism 70 provided, during the process of winding the composite film 100, the pressure roller 72 always keeps the composite film 100 tightly pressed, so that the pressure between the layers of the composite film 100 can be further made consistent, the tightness of each layer of the composite film 100 can be further ensured to be consistent, thereby further avoiding situations such as wrinkling and slackening of the composite film 100, and further preventing air from entering between the layers of the composite film 100, thus further avoiding situations such as bubbles in the composite film 100 and further ensuring the quality of the composite film 100.

[0083] The above is a specific description of the preferred embodiment of the present utility model. However, the present utility model is not limited to the described embodiment. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
