Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery recycling devices, and in particular to a waste film compound machine and a waste film recycling process. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The main function of the diaphragm is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through. The diaphragm material is non-conductive, and its physical and chemical properties have a great influence on the performance of the battery. Different types of batteries use different diaphragms. For lithium battery series, since the electrolyte is an organic solvent system, a diaphragm material that is resistant to organic solvents is required, and a high-strength thin-film polyolefin porous membrane is generally used.

[0003] In the production process of lithium battery separators, due to production, equipment or process reasons, the film often breaks, while the front extrusion equipment is still continuously casting. If the waste film cannot be processed in time, when a large amount of waste film is wrapped around the paper roll, it not only takes up a large storage space, but also affects the turnover of the paper roll. A battery membrane waste collection device with publication number CN108297159A can recycle waste film, but the recycling method has the following problems: 1. It is impossible to directly recycle the waste film on the core; 2.

[0046] like Figure 1 Combined with Figure 4 , Figure 5 , Figure 8 As shown, in one embodiment of the present invention, a waste film compound machine is provided, which is used to recycle the waste film 12 on the unwinding roller 11. The waste film compound machine includes: a fixed frame 10, a rubber pressure roller assembly 20, a first guide roller 30, a winding assembly 50, a first driving member 60, a second driving member 70 and a third driving member 80, wherein the fixed frame 10 includes a box body 101, a support rod 102 and a top plate 103, and the support rod 102 is arranged between the box body 101 and the top plate 103; the first driving member 60, the second driving member 70 and the third driving member 80 are all fixed in the box body 101;

[0047] The pressure roller assembly 20 and the first guide roller 30 are both arranged between the box body 101 and the top plate 103, and the spacing between the pressure roller assembly 20 and the first guide roller 30 is adjustable; the end of the first guide roller 30 facing the box body 101 passes through the box body 101 and is rotatably connected to the first driving member 60; the winding assembly 50 is arranged between the box body 101 and the top plate 103, and the end of the winding assembly 50 facing the box body 101 passes through the box body 101 and is rotatably connected to the second driving member 70; multiple unwinding rollers 11 are detachably arranged between the box body 101 and the top plate 103, and each unwinding roller 11 passes through the box body 101 and is rotatably connected to the third driving member 80 at one end facing the box body 101, and the waste film 12 on the unwinding roller 11 passes through the gap between the pressure roller assembly 20 and the first guide roller 30 and is wound around the winding assembly 50.

[0048] Specifically, one end of the support rod 102 is threadedly connected to the box body 101, and the other end is threadedly connected to the top plate 103. The first drive member 60, the second drive member 70 and the third drive member 80 are all motors, wherein the first guide roller 30 is rotationally connected to the corresponding motor through a pulley, the winding assembly 50 is also rotationally connected to the corresponding motor through a pulley, and the unwinding roller 11 is directly rotationally connected to the output shaft of the corresponding motor.

[0049] When in use, multiple unwinding rollers 11 are directly installed between the box body 101 and the top plate 103. At this time, one end of the unwinding roller 11 is rotatably connected to the corresponding third driving member 80, and the other end of the unwinding roller 11 is rotatably connected to the top plate 103. One end of the rubber pressure roller assembly 20 is rotatably connected to the box body 101, and the other end is rotatably connected to the top plate 103. One end of the first guide roller 30 is rotatably connected to the top plate 103, and the other end is rotatably connected to the first driving member 60. One end of the winding assembly 50 is rotatably connected to the top plate 103, and the other end is rotatably connected to the second driving member 70.

[0050] Then, the first driving member 60, the second driving member 70 and the third driving member 80 are started, the first driving member 60 drives the first guide roller 30 to rotate, the second driving member 70 drives the winding assembly 50 to rotate, and the third driving member 80 drives the unwinding roller 11 to rotate. At this time, the waste film 12 on the unwinding roller 11 passes through the gap between the rubber pressure roller assembly 20 and the first guide roller 30 and is wound around the winding assembly 50, thereby realizing direct recovery of the waste films 12 on multiple unwinding rollers 11; at the same time, since the spacing between the rubber pressure roller assembly 20 and the first guide roller 30 is adjustable, such as Figure 8 As shown, when multiple waste films 12 are recycled at the same time, the corresponding spacing is adjusted so that the output directions of the multiple waste films 12 can be limited at the same time, so that the multiple waste films are wound on the winding assembly 50 after passing through the same direction, which is conducive to the simultaneous recycling of multiple waste films.

[0051] In some embodiments, in order to facilitate the adjustment of the distance between the rubber pressure roller assembly 20 and the first guide roller 30, as shown in FIG. Figure 3 As shown, the rubber pressure roller assembly 20 in the present invention includes a traction roller 201, a first cylinder 202 and a second cylinder 203, wherein the first cylinder 202 is fixed on the side of the top plate 103 facing the box body 101, the second cylinder 203 is fixed on one side of the box body 101, one end of the traction roller 201 is connected to the first cylinder 202 through a first bearing seat, and the other end of the traction roller 201 is connected to the second cylinder 203 through a second bearing seat.

[0052] When in use, the first cylinder 202 drives one end of the traction roller 201 to move through the first bearing seat, and the second cylinder 203 drives the other end of the traction roller 201 to move through the second bearing seat. By synchronously starting the first cylinder 202 and the second cylinder 203, the traction roller 201 can be driven to move toward the first guide roller 30, or driven to move away from the first guide roller 30, so that the distance between the traction roller 201 and the first guide roller 30 can be easily adjusted. For example: when multiple waste films 12 pass between the traction roller 201 and the first guide roller 30 at the same time, the gap between the traction roller 201 and the first guide roller 30 is increased; when only one waste film 12 passes between the traction roller 201 and the first guide roller 30, the gap between the traction roller 201 and the first guide roller 30 is decreased.

[0053] Since the waste film 12 will change the corresponding transmission direction after passing between the traction roller 201 and the first guide roller 30, the present invention simultaneously limits the output directions of multiple waste films 12, so that multiple waste films 12 can be wound around the winding assembly 50 after passing in the same direction, which is beneficial to the simultaneous recovery of multiple waste films.

[0054] In some embodiments, the waste film laminating machine further includes a third bearing seat (not shown in the figure), and one end of the first guide roller 30 facing the top plate 103 is connected to the top plate 103 through the third bearing seat.

[0055] Specifically, the third bearing seat is fixed on the side of the top plate 103 facing the box body 101, and the end of the first guide roller 30 facing the top plate 103 is connected to the bearing on the third bearing seat, so that the first guide roller 30 can be driven to rotate through the first driving member 60.

[0056] In some embodiments, after the waste film 12 is output from between the traction roller 201 and the first guide roller 30, in order to further adjust the conveying direction of the waste film 12 so as to facilitate the waste film 12 to be wound onto the winding assembly 50, as shown in FIG. Figure 1 As shown, the waste film laminating machine further includes an adjusting component 40 , which is disposed on the fixing frame 10 and is used to adjust the conveying direction of the waste film 12 guided out from the gap between the rubber pressure roller assembly 20 and the first guide roller 30 .

[0057] Specifically, Figure 3 As shown, the adjustment component 40 in the present invention includes a second guide roller 401, a first connecting plate 402, a third cylinder 403, a second connecting plate 404 and a fourth cylinder 405, wherein the first connecting plate 402 is rotatably connected to one end of the first guide roller 30 facing the top plate 103, the third cylinder 403 is fixed to the side of the top plate 103 facing the box body 101, and the telescopic end of the third cylinder 403 is connected to the first connecting plate 402 to drive the first connecting plate 402 to rotate around the first guide roller 30; the second connecting plate 404 is rotatably connected to one end of the first guide roller 30 facing the box body 101, and the fourth cylinder 405 is fixed to the side of the top plate 103 facing the box body 101, and the telescopic end of the third cylinder 403 is connected to the first connecting plate 402 to drive the first connecting plate 402 to rotate around the first guide roller 30; the second connecting plate 404 is rotatably connected to one end of the first guide roller 30 facing the box body 101, and the third cylinder 405 is fixed to the side of the top plate 103 facing the box body 101, and the third cylinder 405 is fixed to the side of the top plate 103 facing the box body 101, and the telescopic end of the third cylinder 403 is connected to the first connecting plate 402 to drive the first connecting plate 402 to rotate around the first guide roller 30. The cylinder 405 is fixed on the side of the box body 101 facing the top plate 103, and the telescopic end of the fourth cylinder 405 is connected to the second connecting plate 404, which is used to drive the second connecting plate 404 to rotate around the first guide roller 30; the second guide roller 401 is arranged between the first connecting plate 402 and the second connecting plate 404, and the winding assembly 50 includes a winding roller 501, which is arranged between the box body 101 and the top plate 103. One end of the winding roller 501 facing the box body 101 passes through the box body 101 and is rotatably connected to the second driving member 70, and the position of the winding roller 501 corresponds to the position of the second guide roller 401.

[0058] Exemplarily, the present invention has through holes on both the first connecting plate 402 and the second connecting plate 404 . The through hole on the first connecting plate 402 is sleeved on one end of the first guide roller 30 , and the through hole on the second connecting plate 404 is sleeved on the other end of the first guide roller 30 .

[0059] When in use, the third cylinder 403 drives the first connecting plate 402 to move, and the fourth cylinder 405 drives the second connecting plate 404 to move. Since the second guide roller 401 is arranged between the first connecting plate 402 and the second connecting plate 404, the second guide roller 401 can be driven to move while the first connecting plate 402 and the second connecting plate 404 move. Since the position of the second guide roller 401 corresponds to the position of the winding roller 501 on the winding assembly 50, after the position of the second guide roller 401 is adjusted, after the waste film 12 is output from between the traction roller 201 and the first guide roller 30, the waste film 12 will further change the conveying direction under the further restriction of the second guide roller 401. At this time, the conveying direction of the waste film 12 matches the position of the corresponding winding roller 501, which is conducive to the waste film 12 being wound on the winding roller 501.

[0060] In some embodiments, in order to ensure that the first connecting plate 402 and the second connecting plate 404 are moved at the same distance, so that the second guide roller 401 is always in a vertical state, as shown in FIG. Figure 3As shown, the adjustment assembly 40 of the present invention further includes a connecting rod 406 , one end of which is fixedly connected to the first connecting plate 402 , and the other end of which is fixedly connected to the second connecting plate 404 .

[0061] Since a connecting rod 406 is connected between the first connecting plate 402 and the second connecting plate 404, when the first connecting plate 402 and the second connecting plate 404 move, it is only necessary to ensure that the connecting rod 406 is always in a vertical state, so that the moving distances of the first connecting plate 402 and the second connecting plate 404 can be the same.

[0062] In some embodiments, Figure 6 As shown, the winding assembly 50 of the present invention also includes a first mounting seat 502 and a second mounting seat 503, wherein the first mounting seat 502 is arranged on the top plate 103, the second mounting seat 503 is rotatably connected to the second driving member 70, and the distance between the first mounting seat 502 and the second mounting seat 503 is adjustable, and the winding roller 501 is arranged between the first mounting seat 502 and the second mounting seat 503.

[0063] Specifically, a bearing is provided on the first mounting seat 502, one end of the winding roller 501 is connected to the bearing on the first mounting seat 502, and the other end is connected to the second mounting seat 503. When in use, the second mounting seat 503 is driven to rotate by the second driving member 70, and the second mounting seat 503 can drive the winding roller 501 to rotate.

[0064] Furthermore, since the distance between the first mounting seat 502 and the second mounting seat 503 is adjustable, it is convenient to place the winding roller 501 of different lengths between the first mounting seat 502 and the second mounting seat 503 .

[0065] In some embodiments, Figure 7 As shown, the first mounting seat 502 includes a mounting sleeve 5021, a flange 5022, a screw 5023, a rotating handle 5024 and a connecting head 5025, wherein the flange 5022 is arranged on the mounting sleeve 5021, the mounting sleeve 5021 is a hollow structure with openings at both ends, the inner wall of the mounting sleeve 5021 is provided with an internal thread, the mounting sleeve 5021 is fixed to the top plate 103 through the flange 5022, and the end of the mounting sleeve 5021 facing the box body 101 passes through the top plate 103; the screw 5023 is located in the mounting sleeve 5021, and the screw 5023 is threadedly connected to the mounting sleeve 5021, the end of the screw 5023 away from the box body 101 is connected to the rotating handle 5024, and the end of the screw 5023 facing the box body 101 is connected to the connecting head 5025; the winding roller 501 is arranged between the connecting head 5025 and the second mounting seat 503.

[0066] Specifically, a bearing is provided on the connector 5025, and the end of the winding roller 501 facing the connector 5025 is connected to the corresponding bearing. When the distance between the first mounting seat 502 and the second mounting seat 503 needs to be adjusted, the rotating handle 5024 is driven by an external force to rotate relative to the mounting sleeve 5021, for example, the rotating handle 5024 is driven to rotate clockwise, the rotating handle 5024 drives the screw 5023 to move toward one side of the box body 101, and the screw 5023 drives the connector 5025 to move toward one side of the box body 101. At this time, the distance between the connector 5025 and the second mounting seat 503 becomes smaller, so that a shorter winding roller 501 can be placed between the connector 5025 and the second mounting seat 503, and vice versa.

[0067] In some embodiments, in order to facilitate the installation of the unwinding roller 11, as Figure 2 As shown, the fixed frame 10 also includes a fourth bearing seat 104, a first opening 1011 is provided on the box body 101, a second opening 1031 is provided on the top plate 103, and the fourth bearing seat 104 is arranged on the side of the top plate 103 away from the box body 101; wherein, one end of the unwinding roller 11 passes through the first opening 1011 and is rotatably connected to the third driving member 80, and the other end passes through the second opening 1031 and is rotatably connected to the fourth bearing seat 104.

[0068] The present invention also provides a waste film recycling process, which uses a waste film compound machine such as any one of the embodiments of the present application to recycle waste films.

[0069] Specifically, the waste film recovery process includes the following steps:

[0070] The present invention provides a composite winding method for waste film 12, which is used to recover the waste film 12 on a reel 11, and comprises the following steps:

[0071] The first step: installing a plurality of unwinding rollers 11 with waste films 12 on the waste film laminating machine, and each unwinding roller 11 is connected to a third driving member 80 on the waste film laminating machine;

[0072] Step 2: Install the winding roller 501 on the waste film laminating machine, and connect the winding roller 501 to the second driving member 70 on the waste film laminating machine;

[0073] Step 3: Adjust the distance between the traction roller 201 and the first guide roller 30 on the waste film laminating machine;

[0074] Step 4: Start the third driving member 80, the second driving member 70 and the first driving member 60 on the waste film laminating machine. The third driving member 80 drives the unwinding roller 11 to rotate, the second driving member 70 drives the winding roller 501 to rotate, and the first driving member 60 drives the first guide roller 30 to rotate. At this time, the waste film 12 on each unwinding roller 11 passes through the gap between the traction roller 201 and the first guide roller 30 and is wound around the winding roller 501.

[0075] By adopting the above technical solution, multiple unwinding rollers 11 are directly installed on the waste film laminating machine, and then the third driving member 80, the second driving member 70 and the first driving member 60 are started. The third driving member 80 drives the unwinding roller 11 to rotate, the second driving member 70 drives the winding roller 501 to rotate, and the first driving member 60 drives the first guide roller 30 to rotate. At this time, the waste film 12 on the unwinding roller 11 passes through the gap between the traction roller 201 and the first guide roller 30 and is wound around the winding roller 501, thereby realizing the direct recovery of the waste film 12 on the multiple unwinding rollers 11.

[0076] In some embodiments, the present invention installs the winding roller 501 on the waste film laminating machine, including: adjusting the distance between the first mounting seat 502 and the second mounting seat 503 on the waste film laminating machine, wherein the second mounting seat 503 is connected to the second driving member 70; determining the distance between the first mounting seat 502 and the second mounting seat 503, and selecting the winding roller 501, the length of which matches the distance between the first mounting seat 502 and the second mounting seat 503; and installing the winding roller 501 between the first mounting seat 502 and the second mounting seat 503.

[0077] The present invention facilitates the installation of winding rollers 501 of different lengths by adjusting the distance between the first mounting seat 502 and the second mounting seat 503 .

[0078] Furthermore, in the present invention, adjusting the distance between the first mounting seat 502 and the second mounting seat 503 on the waste film laminating machine includes: rotating the rotating handle 5024 on the first mounting seat 502, the rotating handle 5024 drives the screw 5023 on the first mounting seat 502 to rotate, and the screw 5023 drives the connecting head 5025 on the first mounting seat 502 to approach or move away from the second mounting seat 503. The present invention can achieve the connection head 5025 approaching or moving away from the second mounting seat 503 by rotating the rotating handle 5024, which greatly facilitates the adjustment of the distance between the first mounting seat 502 and the second mounting seat 503.

[0079] In some embodiments, adjusting the distance between the traction roller 201 and the first guide roller 30 on the waste film laminating machine in the present invention includes: starting the first cylinder 202 and the second cylinder 203 on the waste film laminating machine, and the first cylinder 202 and the second cylinder 203 synchronously drive the traction roller 201 to approach or move away from the first guide roller 30.

[0080] The present invention can adjust the distance between the traction roller 201 and the first guide roller 30 through the movement of the first cylinder 202 and the second cylinder 203, which brings convenience to people's use.

[0081] In some embodiments, after step 130 , the method further includes: installing an adjustment component 40 on the waste film laminating machine, wherein the adjustment component 40 is used to adjust the conveying direction of the waste film 12 guided out from the gap between the traction roller 201 and the first guide roller 30 .

[0082] Specifically, the above-mentioned adjustment component 40 includes a second guide roller 401, a first connecting plate 402, a third cylinder 403, a second connecting plate 404 and a fourth cylinder 405; wherein the first connecting plate 402 is rotatably connected to one end of the first guide roller 30 facing the upper top plate 103 of the waste film compounding machine, the third cylinder 403 is fixed on the side of the upper top plate 103 of the waste film compounding machine facing the upper box body 101 of the waste film compounding machine, and the telescopic end of the third cylinder 403 is connected to the first connecting plate 402; the second connecting plate 404 is rotatably connected to one end of the first guide roller 30 facing the upper box body 101 of the waste film compounding machine, the fourth cylinder 405 is fixed on the side of the upper box body 101 of the waste film compounding machine facing the upper top plate 103 of the waste film compounding machine, and the telescopic end of the fourth cylinder 405 is connected to the second connecting plate 404; the second guide roller 401 is arranged between the first connecting plate 402 and the second connecting plate 404, and the position of the second guide roller 401 corresponds to the position of the winding roller 501.

[0083] In the present invention, through holes are provided on both the first connecting plate 402 and the second connecting plate 404 . The through hole on the first connecting plate 402 is sleeved on one end of the first guide roller 30 , and the through hole on the second connecting plate 404 is sleeved on the other end of the first guide roller 30 .

[0084] When in use, the third cylinder 403 drives the first connecting plate 402 to move, and the fourth cylinder 405 drives the second connecting plate 404 to move. Since the second guide roller 401 is arranged between the first connecting plate 402 and the second connecting plate 404, the second guide roller 401 can be driven to move while the first connecting plate 402 and the second connecting plate 404 move. Since the position of the second guide roller 401 corresponds to the position of the winding roller 501 on the winding assembly 50, after the position of the second guide roller 401 is adjusted, after the waste film 12 is output from between the traction roller 201 and the first guide roller 30, the waste film 12 will further change the conveying direction under the further restriction of the second guide roller 401. At this time, the conveying direction of the waste film 12 matches the position of the corresponding winding roller 501, which is conducive to the waste film 12 being wound on the winding roller 501.

[0085] In some embodiments, the composite winding method of the waste film 12 in the present invention further includes: setting a connecting rod 406 between the first connecting plate 402 and the second connecting plate 404 to ensure that the first connecting plate 402 and the second connecting plate 404 move synchronously.

[0086] Since a connecting rod 406 is connected between the first connecting plate 402 and the second connecting plate 404, when the first connecting plate 402 and the second connecting plate 404 move, it is only necessary to ensure that the connecting rod 406 is always in a vertical state, so that the moving distances of the first connecting plate 402 and the second connecting plate 404 can be the same.

[0087] In some embodiments, in order to facilitate the installation of the unwinding roller 11 on the waste film laminating machine, multiple unwinding rollers 11 with waste film 12 are installed on the waste film laminating machine in the present invention, including: grabbing the corresponding unwinding roller 11 with waste film 12 by a robotic arm; after the robotic arm drives the unwinding roller 11 to move to a preset position, the unwinding roller 11 is installed on the waste film laminating machine.

[0088] In some embodiments, in order to prevent the waste film 12 on the winding roller 501 from continuing to work after reaching saturation, after step 140, the method further includes: when the waste film 12 on the winding roller 501 reaches a preset amount, turning off the third driving member 80, the second driving member 70 and the first driving member 60.

[0089] In some embodiments, when the waste film 12 on the winding roller 501 reaches a preset amount, the method further includes: removing the winding roller 501 from the waste film laminating machine; and removing the waste film 12 on the winding roller 501 .

[0090] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
