Description

Technical Field

[0001] This application relates to the field of aluminum-plastic film curing, and in particular to a curing device for aluminum-plastic film. Background Technology

[0002] Aluminum-plastic composite film, also known as aluminum-plastic film, is a film product used for product packaging that combines an aluminum foil layer and a plastic film layer. In the lithium battery industry, aluminum-plastic film is used for encapsulating soft-pack lithium batteries. It is a complementary product to the soft-pack lithium battery cells, primarily serving to protect the internal battery materials and isolate the internal cells from the external environment.

[0003] In the production process of aluminum-plastic film, an aluminum layer and a polypropylene film layer are bonded together with an adhesive to form an aluminum-plastic film. The aluminum-plastic film is then wound onto a mandrel and sent into a curing chamber for curing treatment, thereby enabling the aluminum-plastic film to achieve optimal composite strength.

[0004] Currently, in the curing process of aluminum-plastic film, when batches of rolled aluminum-plastic film are transported to the curing chamber, the rolls are manually moved into the curing chamber and hung one by one to facilitate curing. After curing, the aluminum-plastic film is then manually moved from the curing chamber to a shelf, with rollers installed at both ends of the mandrel to allow the rolled aluminum-plastic film to move on the shelf.

[0005] The method of manually suspending rolls of aluminum-plastic film one by one in the curing chamber is inefficient, resulting in a long curing time. Summary of the Invention

[0006] In order to improve the efficiency of hanging rolled aluminum-plastic film in the curing chamber, this application provides a curing device for aluminum-plastic film.

[0007] This application provides a curing device for aluminum-plastic film, which adopts the following technical solution:

[0008] A curing device for aluminum-plastic film includes a heating chamber with a heating device installed on its inner wall. One end of the heating chamber has a feed inlet, and the other end has a discharge outlet. A guide rail is installed on the inner wall of the heating chamber, inclined along the axial direction of the heating chamber. The guide rail supports rollers on a mandrel of rolled aluminum-plastic film. A positioning device is installed inside the heating chamber on the guide rail. The positioning device includes a limiting mechanism and an unlocking mechanism. The limiting mechanism includes several limiting blocks installed on the guide rail, arranged along the length of the guide rail. The limiting blocks limit the rollers on the mandrel. The unlocking mechanism unlocks the limiting mechanism.

[0009] By adopting the above technical solution, during the curing process, the rolled aluminum-plastic film is placed on the guide rail from the feed inlet of the heating chamber. The rolled film then automatically rolls along the guide rail towards the discharge outlet via rollers on its mandrel. Limiting blocks in the limiting mechanism individually limit the rollers on the mandrel, thus automatically suspending the rolled aluminum-plastic film within the curing chamber. This eliminates the need for manual placement, reduces the time required for manual handling, and improves the efficiency of suspending the aluminum-plastic film within the curing chamber. After curing is complete, the limiting mechanism is unlocked via an unlocking mechanism, facilitating the unloading of the aluminum-plastic film.

[0010] In one specific implementation, the end of the guide rail located at the feed inlet is higher than the end of the guide rail located at the discharge outlet.

[0011] By adopting the above technical solution, the rolled aluminum-plastic film is fed into the heating chamber from the feed port, so that the rollers on the mandrel slide along the guide rail, thereby causing the rolled aluminum-plastic film to slide from the feed port to the discharge port. The limiting mechanism limits the movement, thereby suspending the rolled aluminum-plastic film in the heating chamber for curing treatment.

[0012] In one specific implementation scheme, the limiting mechanism further includes a linkage component, which includes a folding plate and a return spring. One end of the folding plate is a support part, and the other end of the folding plate is a control part. The included angle between the support part and the control part is an obtuse angle. An installation groove is provided on the guide rail. The folding plate is rotatably installed in the installation groove. The return spring is installed in the installation groove, and one end of the return spring is connected to the inner wall of the installation groove, while the other end is connected to the control part of the folding plate. The support part is connected to the limiting block, and the control part is used to support the rollers on the spindle.

[0013] By adopting the above technical solution, when the first roll of aluminum-plastic film moves to the control section of the folding plate via the rollers on the mandrel, the rollers abut against the side wall of the control section, thus facilitating buffering and simultaneously pushing the control section downwards. This causes the support section to rotate upwards, abutting against the side wall of the limiting block near the folding plate, thereby lifting the limiting block to limit the rollers on the mandrel of the next roll of aluminum-plastic film. By repeating the above steps, several rolls of aluminum-plastic film can be suspended and arranged on the guide rail.

[0014] In one specific implementation, one end of the limiting block is rotatably connected to the support portion of the guide rail near the folding plate, and the side wall of the limiting block near the folding plate is slidably connected to the support portion of the folding plate, and the side wall of the limiting block away from the folding plate is used to abut against the roller on the spindle.

[0015] By adopting the above technical solution, after the roller on the mandrel of the previous roll of aluminum-plastic film drives the control unit to rotate downward, the support unit supports the limiting block located near the support unit, so that the limiting block can limit the roller on the mandrel of the next roll of aluminum-plastic film, thereby stopping the movement of the next roll of aluminum-plastic film.

[0016] In one specific implementation, at least one limiting block is provided, and the limiting blocks are arranged along the axial direction of the guide rail, with each limiting block corresponding to a folding plate and a return spring.

[0017] By adopting the above technical solution, by setting at least one limiting block and arranging at least one limiting block on the guide rail, it is convenient to suspend multiple rolls of aluminum-plastic film on the guide rail.

[0018] In one specific implementation, the limiting mechanism further includes a stop block, which is rotatably mounted on one end of the guide rail located at the discharge port. The side wall of the stop block at the end away from the guide rail is used to abut against the roller on the mandrel. A connecting block is installed at the end of the stop block connected to the guide rail. The connecting block extends into the guide rail and is connected to the unlocking mechanism.

[0019] By adopting the above technical solution, when the first roll of aluminum-plastic film is placed on the guide rail, the roller on the mandrel slides along the guide rail toward the discharge port, thereby moving to the stop block and contacting the stop block, thus achieving the positioning of the first roll of aluminum-plastic film.

[0020] In one specific implementation, the unlocking mechanism includes an unlocking rod and an unlocking cylinder. The unlocking rod is slidably installed inside the guide rail along the axial direction of the guide rail, with one end of the unlocking rod extending outward from the guide rail. The unlocking rod is slidably connected to a connecting block. The unlocking cylinder is installed on the inner wall of the heating chamber, with the axis of the piston rod of the unlocking cylinder parallel to the axis of the guide rail. The piston rod of the unlocking cylinder is connected to the end of the unlocking rod located outside the guide rail.

[0021] By adopting the above technical solution, after the curing is completed, the unlocking cylinder drives the unlocking rod to move along the axis of the guide rail, thereby causing the unlocking rod to drive the connecting block to rotate, which in turn causes the stop block to rotate downward, thereby releasing the limit on the roller on the core shaft of the first roll of aluminum-plastic film, thus facilitating the unloading of the first roll of aluminum-plastic film.

[0022] In one specific implementation scheme, a baffle is installed at the upper end of the guide rail along the axial direction of the guide rail, a feeding notch is provided at one end of the guide rail near the feed inlet, and a discharge notch is provided at one end of the guide rail near the discharge outlet.

[0023] By adopting the above technical solution, when the rolled aluminum-plastic film needs to be suspended in the heating chamber, the rollers on the mandrel enter the guide rail from the feeding notch as the rolled aluminum-plastic film is transported from the feeding port to the guide rail, thereby realizing movement along the guide rail. When unloading is required, the rollers on the mandrel move out of the guide rail from the discharge notch, thus facilitating the removal of the aluminum-plastic film from the heating chamber.

[0024] In one specific implementation, an insulation board is installed on the inner wall of the heating chamber.

[0025] By adopting the above technical solution, an insulation board is installed on the inner wall of the heating chamber, which helps to maintain the temperature inside the heating chamber and thus improves the curing effect of the aluminum-plastic film.

[0026] In one specific implementation, a circulating fan is also installed in the heating chamber to circulate the air within the heating chamber.

[0027] By adopting the above technical solution and setting up a circulating fan, the air in the heating chamber can be circulated, which makes the temperature in the heating chamber more uniform and thus improves the curing effect.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. This application, by setting a positioning device and a slanted guide rail, facilitates the automatic conveying of rolled aluminum-plastic film into the heating chamber via the slanted guide rail, and positions each rolled aluminum-plastic film individually through the positioning device, thereby improving the efficiency of hanging rolled aluminum-plastic film in the heating chamber.

[0030] 2. This application provides a stop block and at least one limit block to facilitate the limiting of the rollers on the core shaft of the rolled aluminum-plastic film, thereby making it easier to suspend the rolled film one by one in the heating box.

[0031] 3. This application provides an unlocking mechanism to facilitate the unlocking of the positioning mechanism, thereby making it easier for the rolled aluminum-plastic film to be transported out of the heating chamber. Attached Figure Description

Detailed Implementation

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] This application discloses a curing device for aluminum-plastic film, referring to... Figure 1 and Figure 2 The heating chamber includes a heating chamber 1, with an inlet 11 at one end and an outlet 12 at the other end. A heating device (not shown in the figure) is installed on the inner wall of the heating chamber 1; this heating device is existing technology and will not be described in detail here. Guide rails 2 are fixedly installed on the inner walls of both sides of the heating chamber 1. The guide rails 2 extend along the axial direction of the heating chamber 1 from the inlet 11 to the outlet 12, with the end of the guide rail 2 at the inlet 11 higher than the end at the outlet 12. The guide rails 2 support the rollers 61 on the mandrel 6 of the rolled aluminum-plastic film, and a positioning device 3 is installed on the guide rails 2.

[0042] Reference Figure 1 and Figure 2 The rolled aluminum-plastic film is transported to the feed inlet 11, and then the rolled aluminum-plastic film is transported to the guide rail 2 through the feed inlet 11, so that the roller 61 on the spindle 6 of the rolled aluminum-plastic film slides along the guide rail 2, thereby moving the rolled aluminum-plastic film towards the discharge port 12, and is positioned by the positioning device 3 set on the guide rail 2, thereby suspending the rolled aluminum-plastic film in the heating chamber 1.

[0043] Reference Figure 1A baffle 22 is fixedly installed on the side wall of the guide rail 2 near the inner wall of the heating chamber 1. The baffle 22 is arranged along the axis of the guide rail 2, and a space is left between the baffle 22 and the top wall of the guide rail 2 for the roller 61 on the mandrel 6 of the rolled aluminum-plastic film to pass through. A feeding notch 23 is opened at the end of the guide rail 2 near the feeding port 11, and a discharging notch 24 is opened at the end of the guide rail 2 near the discharging port 12.

[0044] Reference Figure 3 and Figure 4 The positioning device 3 includes a limiting mechanism 31, which comprises a stop block 312, several limiting blocks 311, and a linkage assembly 313. The stop block 312 is installed at one end of the guide rail 2 located at the discharge port 12, with one end of the stop block 312 rotatably connected to the bottom wall of the guide rail 2, and the other end extending away from the guide rail 2. The other end of the stop block 312 is inclined towards the discharge port 12, and the side wall of the stop block 312 away from the discharge port 12 is used to abut against the roller 61 on the mandrel 6 of the rolled aluminum-plastic film. When the rolled aluminum-plastic film needs to be unloaded, the stop block 312 is controlled to rotate so that the surface of the stop block 312 that abuts against the roller 61 on the mandrel 6 of the rolled aluminum-plastic film is on the same plane as the bottom wall of the guide rail 2.

[0045] Reference Figure 3 and Figure 4 A mounting groove 21 is provided on the bottom wall of the guide rail 2. The width of the mounting groove 21 is smaller than the width of the roller 61 on the mandrel 6 of the rolled aluminum-plastic film. One end of the limiting block 311 is rotatably mounted in the mounting groove 21 on the guide rail 2, and the other end of the limiting block 311 extends away from the guide rail 2. The end of the limiting block 311 away from the guide rail 2 also tilts towards the discharge port 12. The side wall of the limiting block 311 away from the discharge port 12 is used to abut against the roller 61 on the mandrel 6 of the rolled aluminum-plastic film. Several limiting blocks 311 are arranged on the guide rail 2 from near the stop block 312 towards the feed port 11. The distance between two adjacent limiting blocks 311 is greater than the diameter of the rolled aluminum-plastic film, and the distance between the limiting block 311 near the stop block 312 and the stop block 312 is also greater than the diameter of the rolled aluminum-plastic film. The linkage component 313 is installed on the guide rail 2, and the linkage component 313 is connected to the limit block 311.

[0046] Reference Figure 4The linkage component 313 includes a folding plate and a return spring 3133. Several folding plates and return springs 3133 are provided, and each limiting block 311 corresponds to one folding plate and one return spring 3133. The folding plate is installed in the mounting groove 21, with one end serving as a support part 3132 and the other end as a control part 3131. The angle between the support part 3132 and the control part 3131 is obtuse, and the connection between the support part 3132 and the control part 3131 is rotatably connected to the side wall of the mounting groove 21. The support part 3132 extends away from the stop block 312 to the limiting block 311, and is located below the limiting block 311. The return spring 3133 is installed in the mounting groove 21 near the control part 3131 of the folding plate. One end of the return spring 3133 is fixedly connected to the bottom wall of the mounting groove 21, and the other end is fixedly connected to the bottom wall of the control part 3131.

[0047] Reference Figure 4 When the first roll of aluminum-plastic film is conveyed onto the guide rail 2, the roller 61 on the spindle 6 of the roll of aluminum-plastic film slides along the guide rail 2 to the stop block 312. The stop block 312 stops the roll of aluminum-plastic film from moving. At this time, the roller 61 presses down on the control part 3131, causing the control part 3131 to press the reset spring 3133, thereby causing the folding plate to rotate, which in turn causes the support part 3132 to rotate upward, thereby driving the first limiting block 311 adjacent to the stop block 312 to rotate upward. The end of the support part 3132 slides along the side wall of the limiting block 311 and supports the limiting block 311, making the limiting block 311 tilted.

[0048] Reference Figure 3 and Figure 4 When the second roll of aluminum-plastic film is conveyed onto the guide rail 2, the roller 61 on the mandrel 6 of the roll of aluminum-plastic film moves along the guide rail 2 toward the stop block 312. When the roller 61 moves to the limiting block 311 adjacent to the stop block 312, the roller 61 abuts against the side wall of the limiting block 311, thereby stopping the roller 61 and stopping the roll of aluminum-plastic film at its current position. At this time, the roller 61 has just moved to the control part 3131 of another folding plate. The control part 3131 is pressed down, causing the support part 3132 of the folding plate to rotate upward, thereby driving the limiting block 311 adjacent to the limiting block 311 near the end of the guide rail 2 to rotate upward. The support part 3132 supports the limiting block 311, so that the limiting block 311 can limit the roller 61 on the mandrel 6 of the third roll of aluminum-plastic film, thereby realizing the sequential limiting of the rolls of aluminum-plastic film conveyed to the guide rail 2.

[0049] Reference Figure 4 and Figure 5The positioning device 3 also includes an unlocking mechanism 32, which includes an unlocking cylinder 321 and an unlocking rod 322. The unlocking cylinder 321 is fixedly installed on the inner wall of the heating chamber 1 near the guide rail 2, and the axis of the piston rod of the unlocking cylinder 321 is parallel to the axis of the guide rail 2. A connecting block 324 is also fixedly provided at one end of the stop block 312 connected to the guide rail 2. The connecting block 324 is integrally formed with the stop block 312, extends into the interior of the guide rail 2, and the included angle between the connecting block 324 and the stop block 312 is an obtuse angle. A waist-shaped hole 325 is provided on the side wall of the connecting block 324. A sliding groove 326 is provided on the side wall of the connecting block 324 located within the waist-shaped hole 325. The unlocking rod 322 is slidably installed in the guide rail 2 near the connecting block 324. The axis of the unlocking rod 322 is parallel to the axis of the guide rail 2, and one end of the unlocking rod 322 passes through the waist-shaped hole 325. A push rod 323 is fixedly installed on the side wall of the unlocking rod 322. The push rod 323 is slidably installed in the sliding groove 326. A rotating groove for the connecting block 324 to rotate is also provided in the guide rail 2 at the location of the connecting block 324. The end of the unlocking rod 322 away from the push rod 323 extends out of the side wall of the end of the guide rail 2. A connecting plate 327 is fixedly installed on the end of the unlocking rod 322 outside the guide rail 2. The end of the connecting plate 327 away from the unlocking rod 322 is fixedly connected to the piston rod of the unlocking cylinder 321.

[0050] Reference Figure 6 When unloading is required, the unlocking cylinder 321 controls the unlocking rod 322 to slide within the guide rail 2. This causes the unlocking rod 322 to rotate the connecting block 324 via the push rod 323, which in turn causes the stop block 312 to rotate downwards. This releases the stop block 312 from limiting the roller 61 on the mandrel 6 of the rolled aluminum-plastic film, facilitating the unloading of the rolled aluminum-plastic film located at the stop block 312. After the aluminum-plastic film at the stop block 312 has been unloaded, the unlocking cylinder 321 moves the unlocking rod 322 back to its original position. This causes the unlocking rod 322 to rotate the connecting block 324 via the push rod 323, which in turn causes the stop block 312 to rotate upwards and back to its original position.

[0051] Reference Figure 4 and Figure 6When the aluminum-plastic film originally located at the stop block 312 leaves the guide rail 2, the control part 3131 located near the stop block 312 rotates upward under the action of the return spring 3133, thereby driving the support part 3132 to rotate downward. This causes the end of the support part 3132 to slide downward along the side wall of the limiting block 311, so that the limiting block 311 adjacent to the stop block 312 rotates downward to be on the same plane as the top wall of the guide rail 2. This facilitates the movement of the rolled aluminum-plastic film located at the limiting block 311 to the stop block 312 via the roller 61 on its spindle 6. The stop block 312 then re-limits the film and drives the control plate located at the stop block 312 to rotate again. This causes the support part 3132 to lift the limiting block 311 adjacent to the stop block 312, thus facilitating the limiting of the next rolled aluminum-plastic film.

[0052] Reference Figure 4 When the aluminum-plastic film located at the limiting block 311 adjacent to the stop block 312 moves to the stop block 312, the roller 61 on the spindle 6 of the aluminum-plastic film separates from the control part 3131 located near the limiting block 311. This causes the control part 3131 to rotate upward under the action of the return spring 3133, thereby driving the support part 3132 connected to the control part 3131 to rotate downward. This causes the limiting block 311 adjacent to the limiting block 311 near the end of the guide rail 2 to rotate downward. This causes the limiting block 311 to release the limiting of the rolled aluminum-plastic film located at the limiting block 311, allowing the rolled aluminum-plastic film to continue moving along the guide rail 2 to the limiting block 311 adjacent to the stop block 312. The limiting block 311 adjacent to the stop block 312 then limits the rolled aluminum-plastic film. The rolled aluminum-plastic film on guide rail 2 moves sequentially toward stop block 312 to the next limit block 311 according to the above steps.

[0053] Reference Figure 1 An insulation board 4 is fixedly installed on the inner wall of the heating chamber 1. A circulating fan 5 is also fixedly installed on the top wall of the heating chamber 1 to circulate the air inside the heating chamber 1. An exhaust port for discharging gas from the heating chamber 1 is also installed on the top wall of the heating chamber 1.

[0054] The working principle of this embodiment is as follows: When curing is required, the rolled aluminum-plastic film is conveyed onto the guide rail 2, so that the roller 61 on the mandrel 6 of the rolled aluminum-plastic film enters the conveying rail from the feed notch 23 and moves along the inclined guide rail 2 toward the discharge port 12, thereby moving to the stop block 312, thereby limiting the rolled aluminum-plastic film by the stop block 312. At this time, the roller 61 on the mandrel 6 of the rolled aluminum-plastic film presses down on the control part 3131 of the folding plate located at the stop block 312, and the control part 3131 provides buffering. At the same time, the control part 3131 drives the support part 3132 of the folding plate to rotate upward, thereby causing the support part 3132 to push the limiting block 311 adjacent to the stop block 312 to rotate upward, thereby causing the limiting block 311 to be in an inclined state.

[0055] The second roll of aluminum-plastic film is then fed into the heating chamber 1, causing it to move along the guide rail 2 toward the stop block 312. When the roller 61 on the spindle 6 of the second roll of aluminum-plastic film moves to the limiting block 311 adjacent to the stop block 312, the limiting block 311 limits the roller 61 on the spindle 6 of the second roll of aluminum-plastic film. The roller 61 is positioned on the control part 3131 of the folding plate located near the limiting block 311, and the control part 3131 is pressed down, thereby buffering the roller 61. At the same time, the support part 3132 of the folding plate pushes the limiting block 311 adjacent to the stopping block 312 upward, so that the limiting block 311 is tilted to limit the roller 61 on the spindle 6 of the next roll of aluminum-plastic film.

[0056] After the curing process is completed, the unlocking cylinder 321 moves the unlocking rod 322, which in turn drives the connecting block 324 to rotate via the push rod 323. This causes the stop block 312 to rotate downwards, separating it from the roller 61 on the mandrel 6 of the rolled aluminum-plastic film located at the stop block 312. This allows the roller 61 to continue moving along the guide rail 2 towards the discharge port 12. The rolled aluminum-plastic film is then removed from the guide rail 2 through the discharge notch 24 and transported away from the heating chamber 1 through the discharge port 12, thus completing the unloading of the rolled aluminum-plastic film. Then, the unlocking cylinder 321 controls the unlocking rod 322 to reset, causing the unlocking rod 322 to drive the stop block 312 to rotate upwards via the push rod 323, thus limiting the movement of the roller 61 on the mandrel 6 of the next rolled aluminum-plastic film.

[0057] Subsequently, as the roller 61 on the spindle 6 of the rolled aluminum-plastic film separates from the control part 3131 near the stop block 312, the control part 3131 rotates upward and resets under the action of the reset spring 3133. As a result, the support part 3132 of the folding plate rotates downward and resets. This causes the limiting block 311 adjacent to the stop block 312 to rotate downward and reset under the action of gravity. This causes the limiting block 311 to separate from the roller 61 located at the limiting block 311. As a result, the roller 61 drives the rolled aluminum-plastic film to move along the guide rail 2 to the stop block 312, where the stop block 312 positions the roller 61. When the roller 61 moves to the stop block 312, the control part 3131 of the folding plate near the limiting block 311 adjacent to the stop block 312 separates from the roller 61, causing the control part 3131 to rotate upward and reset under the action of the return spring 3133. This causes the support part 3132 of the folding plate to rotate downward, causing the limiting block 311 adjacent to the stop block 312 to rotate downward under the action of gravity. This releases the limitation on the roller 61 of the mandrel 6 of the next roll of aluminum-plastic film. The roller 61 located at the stop block 312 presses down on the control part 3131 of the folding plate located at the stop block 312, causing the control part 3131 to drive the support part 3132 to rotate upward, thereby supporting the support part 3132 to limit the roller 61 on the mandrel 6 of the next roll of aluminum-plastic film.

[0058] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
