Description

Technical Field

[0001] The present invention belongs to the technical field of battery packaging, and specifically relates to a thermal composite device and process for processing aluminum-plastic films. Background Art

[0002] The aluminum-plastic composite packaging film is an important packaging method for lithium batteries. Compared with aluminum shells, steel shells, and cylindrical packages, the aluminum-plastic composite packaging film has advantages such as good safety performance, high energy density, low internal resistance, and flexible design. Existing aluminum-plastic composite films are usually prepared by co-extrusion and lamination methods.

[0003] The lamination method laminates multiple plastic films and aluminum foils together through a hot pressing device. The formed aluminum-plastic composite film has characteristics such as uniform thickness and high strength, so it is widely used. When the aluminum-plastic composite film is prepared by lamination, the cast polypropylene film in the middle layer absorbs less heat. Therefore, the connection strength of the inner layer of the film after hot pressing is low and it is easy to loosen, which in turn leads to poor overall structural stability of the film body. Therefore, the production process needs to be improved. Summary of the Invention

[0004] In view of the problem of uneven heating during the lamination of existing aluminum-plastic composite packaging films, the technical solution adopted by the present invention is: a thermal composite device for processing aluminum-plastic films, including a processing chamber and a film winding device. The processing chamber includes:

[0005] A heat preservation box, the inner cavity of which is provided with a heat insulation layer;

[0006] A guiding shell, the outer surface of which is inserted into the right side of the inner cavity of the heat preservation box through a through guiding port, and the internal through port of which is adapted to the pressurized aluminum-plastic film;

[0007] A preprocessing component, which can perform preheating treatment on each film and compress the spacing between each film at the same time;

[0008] A lamination component, which can perform pressurization on five film bodies and laminate the film bodies into an aluminum-plastic composite film;

[0009] A docking box for accommodating the film winding device, which can be docked with or separated from the heat preservation box, and can form a relatively sealed box body after being docked with the heat preservation box.

[0010] Furthermore, the film winding device includes:

[0011] A guiding slide plate, the inner cavity of which is provided with a guiding chute;

[0012] Connecting socket tube, at the axis center of the inner cavity of the connecting socket tube, a rotating motor is fixedly connected through a bent rod, and the outer surface of the connecting socket tube is slidably connected with the inner cavity of a guiding sliding plate through a guiding chute. The guiding sliding plate controls the connecting socket tube to slide directionally along the guiding chute through a conveyor belt in the inner cavity;

[0013] Film winding tube, inside the film winding tube, a feeding reel is arranged through a rotating shaft, and the top end of the output shaft of the rotating motor is inserted into the rotating shaft. After the rotating motors on both sides are pulled apart by the connecting socket tube, the film winding tube can be removed to replace the feeding reel inside. The feeding reels inside each layer of film winding tube are different. The feeding reel in the inner layer is a cast polypropylene film, aluminum foils are arranged at the middle parts on the upper and lower sides of the cast polypropylene film, and nylon films are arranged at the surface parts.

[0014] Further, the pretreatment component includes:

[0015] Vertical guiding plate, the outer surface of the vertical guiding plate is fixedly connected with the inner wall of the heat preservation box. On both sides of the outer surface of the vertical guiding plate, guiding chutes are symmetrically arranged, and composite plates are uniformly arranged on the inner wall of the vertical guiding plate through the guiding chutes;

[0016] Among them, the composite plate has:

[0017] Bridging shell, a partition plate is fixedly connected to the middle of the inner cavity of the bridging shell;

[0018] Heating plate, two heating plates are arranged inside each bridging shell, and the bridging shell isolates the heating plates on the upper and lower sides through the partition plate. One side of the heating surface of the heating plate extends to the outside of the bridging shell through a large notch;

[0019] Outer control board, both sides of the outer control board are fixedly connected with the inner cavity of the heating plate through inserting rods, and the middle of the outer surface of the outer control board is fixedly connected with the outer surface of the bridging shell. The outer control board directly controls the heating temperature of the heating plates on the upper and lower sides, so that the heating temperature of each heating plate is different;

[0020] Contact roller, the outer surface of the contact roller is rotatably connected with the side surface of the bridging shell. At the front and rear ends of the axis center of the contact roller, connecting sliding parts are fixedly connected, and the bottom ends of the connecting sliding parts are slidably connected with the inner wall of the vertical guiding plate through the guiding chutes. Since the thickness of the bridging shell is smaller than the diameter of the contact roller, the heating surface part of the heating plate will not contact the outer surface of the film body.

[0021] Further, the laminating component includes:

[0022] Container, the outer surface of the container is fixedly connected with the axis center of the inner wall of the heat preservation box;

[0023] A guiding roller, the axis of the guiding roller is rotatably connected to the inner wall of the container through a motor. The guiding roller can actively rotate under the action of the motor to drive the film body into the interior of the container, and can also slide the pressurized film body out of the interior of the container;

[0024] A threaded end sleeve, the middle of the outer surface of the threaded end sleeve is fixedly connected to the axis of the inner cavity of the container through a through hole.

[0025] The laminating component further includes:

[0026] Pressing torque machines, the number of the pressing torque machines is two, and the outer surfaces of the pressing torque machines are fixedly connected to the inner wall of the heat preservation box;

[0027] A transmission torque rod, the axis of the inner cavity of the transmission torque rod is fixedly connected to the outer surface of the output shaft of the pressing torque machine;

[0028] A threaded rotating rod, the outer surface of the threaded rotating rod is threadedly connected to the inner wall of the threaded end sleeve, and the axis of the inner wall of the threaded rotating rod is inserted into the outer surface of the transmission torque rod through a plugging groove;

[0029] Pressing frames, the number of the pressing frames is two, and the pressing frames are arranged at one end of the threaded rotating rod away from the pressing torque machine.

[0030] Further, the pressing frame includes:

[0031] Counterweight sliding plates, the number of the counterweight sliding plates is two. An inner plate capable of heating the film body is arranged in the middle area of the counterweight sliding plates, and a pressure-sensitive alarm is installed in the inner cavity of the counterweight sliding plates. The front and rear sides of the outer surface of the counterweight sliding plates are both slidably connected to the inner wall of the container to prevent the counterweight sliding plates from rotating automatically as the threaded rotating rod rotates and being misaligned with the pressurized film body;

[0032] Docking sleeves, fixedly installed at the axis of the outer surface of the counterweight sliding plates, and the inner wall of the docking sleeves is rotatably connected to one end of the threaded rotating rod away from the pressing torque machine. A rotating ring adapted to the rotating groove of the inner wall of the docking sleeve is arranged at the bottom position of the threaded rotating rod to ensure the stability of the connection between the docking sleeve and the threaded rotating rod and enable the docking sleeve and the threaded rotating rod to rotate;

[0033] Sliding pressing plates, the outer surfaces of the sliding pressing plates are slidably connected to the bottom of the inner cavity of the counterweight sliding plates, and the bottom ends of the sliding pressing plates extend to the outside of the counterweight sliding plates. The tops of the sliding pressing plates are fixedly connected to the inner cavity of the pressure-sensitive alarm through pressure-sensitive springs. When the upper and lower sliding pressing plates are butted and pressed, they will gradually shrink into the interior of the counterweight sliding plates, and then trigger the pressure-sensitive alarm through the pressure-sensitive springs. When the pressure received by the pressure-sensitive alarm reaches a certain threshold, an alarm sound will be emitted.

[0034] Further, the docking box includes:

[0035] Docking shell, the inner wall of the docking shell is fixedly connected to the outer surface of the guiding slide plate. The right side of the outer surface of the docking shell is inserted into the left side of the outer surface of the heat preservation box, and jet grooves are symmetrically opened on the right side of the inner wall of the docking shell;

[0036] Pressing plate, the outer surface of the pressing plate is fixedly connected to the inner cavity of the docking shell, and the jet ports on both sides of the outer surface of the pressing plate are communicated with the jet grooves;

[0037] Suction plate, one side of the outer surface of the suction plate extends to the outside of the docking box, and the other side of the outer surface of the suction plate is communicated with the inner cavity of the pressing plate. The pressing plate directly sucks and pressurizes from the outside through the suction plate.

[0038] The beneficial effects of the present invention are as follows:

[0039] 1. The device can laminate cast polypropylene film, aluminum foil film and nylon film to form a finished aluminum-plastic composite packaging film. Before the lamination work, the pretreatment component will first heat the middle cast polypropylene film and supplement the heat of the inner layer of aluminum foil, so as to ensure that during the lamination process of the film body, the heat absorption of the cast polypropylene film, aluminum foil film and nylon film will not have a large deviation, effectively improving the connection strength of the inner layer of the film body after hot pressing and ensuring that the laminated film body has high stability.

[0040] 2. Since before the lamination work, the vertical guiding plate will reduce the distance between each film body by means of composite plate compression and perform separate preheating treatment, the film body will not undergo large bending deformation when entering a narrower container, and thus the problem of the film belt breaking will not occur. And after the heat treatment, the film belt will not have obvious expansion deformation when undergoing hot lamination work, so as to ensure that the stacked film belts can directly perform lamination work in the middle area of the counterweight slide plate without dislocation problems.

[0041] 3. When the lamination component laminates the film belt, the pressing torque machines located on the upper and lower sides will convert the torque into the extrusion force of the pressing frame in the vertical plane through the threaded rotating rod, so as to provide the extrusion force. Since when the threaded rotating rod rotates along the threaded end sleeve, the movement amplitude of the slip in the vertical plane will be controlled within a small range, there will be no problem that the counterweight slide plate is difficult to control the movement range due to excessive propulsion force, resulting in the laminated film belt suddenly being subjected to a sudden increase in pressure and undergoing excessive extrusion.

[0042] 4. During the lamination of the film tape by the counterweight sliding plates on the upper and lower sides, the internal pressure-sensitive alarm will be continuously pressed by the sliding pressure plate docked at the bottom, thereby ensuring that the extrusion force of the counterweight sliding plates on the film tape during lamination has a maximum limit value, avoiding the problem that the extrusion force applied by the counterweight sliding plates to the film tape is too large, resulting in the film tape being broken or severely deformed and unable to be used, leading to the scrapping of the film tape.

[0058] The pretreatment component 4 is capable of preheating each film and compressing the distance between each film;

[0059] The laminating component 5 is capable of pressurizing the five membranes to laminate the membranes into aluminum-plastic composite membranes;

[0060] The docking box 1 is used to accommodate the film rolling device 2, and can be docked with or separated from the thermal insulation box 31. After docking with the thermal insulation box 31, a relatively sealed box body can be formed.

[0061] The film rolling device 2 includes:

[0062] A guide slide plate 21, wherein the inner cavity of the guide slide plate 21 is provided with a guide groove 42;

[0063] The connecting plug 22 is fixedly connected to a rotating motor 23 at the axis of the inner cavity of the connecting plug 22 through a bent rod, and the outer surface of the connecting plug 22 is slidably connected to the inner cavity of the guide slide 21 through a guide groove 42, and the guide slide 21 controls the connecting plug 22 to slide along the guide groove 42 through the rotating belt of the inner cavity;

[0064] The film winding cylinder 25 has a feeding reel 24 arranged inside through a rotating shaft, and the top end of the output shaft of the rotating motor 23 is inserted into the rotating shaft. After the two rotating motors 23 on both sides are pulled apart by the connecting insertion cylinder 22, the film winding cylinder 25 can be removed to replace the feeding reel 24 inside. The feeding reels 24 inside each layer of the film winding cylinder 25 are different. The feeding reel 24 in the inner layer is a cast polypropylene film, with aluminum foil provided at the middle parts on the upper and lower sides of the cast polypropylene film, and nylon film provided at the surface part.

[0065] The pretreatment component 4 includes:

[0066] A vertical guide plate 41, the outer surface of the vertical guide plate 41 is fixedly connected to the inner wall of the heat preservation box 31. Guide chutes 42 are symmetrically arranged on both sides of the outer surface of the vertical guide plate 41, and composite plates 43 are uniformly arranged on the inner wall of the vertical guide plate 41 through the guide chutes 42;

[0067] Among them, the composite plate 43 has:

[0068] A bridging shell 431, and a partition plate 432 is fixedly connected to the middle part of the inner cavity of the bridging shell 431;

[0069] A heating plate 433, two heating plates 433 are arranged inside each bridging shell 431, and the bridging shell 431 isolates the upper and lower heating plates 433 through the partition plate 432. One side of the heating surface of the heating plate 433 extends to the outside of the bridging shell 431 through a large notch;

[0070] An outer control board 434, both sides of the outer control board 434 are fixedly connected to the inner cavity of the heating plate 433 through insertion rods, the middle part of the outer surface of the outer control board 434 is fixedly connected to the outer surface of the bridging shell 431, and the outer control board 434 directly controls the heating temperature of the upper and lower heating plates 433, so that the heating temperatures of each heating plate 433 are different;

[0071] A contact roller 435, the outer surface of the contact roller 435 is rotatably connected to the side surface of the bridging shell 431. Both the front and rear ends of the axis center of the contact roller 435 are fixedly connected with connecting sliding parts 436, and the bottom ends of the connecting sliding parts 436 are slidably connected to the inner wall of the vertical guide plate 41 through the guide chutes 42. Since the thickness of the bridging shell 431 is smaller than the diameter of the contact roller 435, the heating surface part of the heating plate 433 will not contact the outer surface of the film body.

[0072] Before using the device for the lamination of the aluminum-plastic composite packaging film, first open the docking box 1, pull open the connecting sockets 22 on both sides of each guiding slide plate 21, remove the film roll cylinder 25 in the middle, place different film rolls according to the position, the casting polypropylene film is arranged inside the film roll cylinder 25 in the middle layer, the aluminum foil film is arranged on the film roll cylinders 25 on both sides of the inner layer, and the nylon film is arranged on the film roll cylinders 25 on both sides of the outer layer. Then, pull out the end parts of each film roll from the slots of the film roll cylinder 25 and slide them out along the guiding shell 32. Then, dock the docking box 1 with the insulation box 31 to complete the preparation work.

[0073] Before the five-layer film body enters the lamination component 5, it will first pass through the pretreatment component 4. At this time, the vertical guiding plate 41 will drive each composite plate 43 to move towards the direction close to the midline through the connecting sliding part 436, and then squeeze the film body through the contact roller 435, thereby preliminarily compressing the five-layer film body. Since the film body does not contact the external heating surface of the heating plate 433, the external control plate 434 can directly energize the heating plate 433 at this time, and then the heating plate 433 heats the outer surface of the adjacent film body. And the temperature of the heating plate 433 close to the casting polypropylene film in the middle layer is higher. The pre-heated film body then enters the lamination component 5 for heating and lamination work, and is pressed into an aluminum-plastic composite packaging film and transported out from the guiding shell 32.

[0074] Example 2, please refer to Figures 1 - 10 , the present invention provides a technical solution: on the basis of Example 1, the lamination component 5 includes:

[0075] A container 51, the outer surface of the container 51 is fixedly connected to the axis of the inner wall of the insulation box 31;

[0076] A guiding roller 52, the axis of the guiding roller 52 is rotatably connected to the inner wall of the container 51 through a motor. The guiding roller 52 can actively rotate under the action of the motor, drive the film body into the interior of the container 51, and can also slide the pressurized film body out of the interior of the container 51;

[0077] A threaded end sleeve 53, the middle of the outer surface of the threaded end sleeve 53 is fixedly connected to the axis of the inner cavity of the container 51 through a through hole.

[0078] The lamination component 5 further includes:

[0079] Pressing torque machines 54, the number of the pressing torque machines 54 is two, and the outer surfaces of the pressing torque machines 54 are fixedly connected to the inner wall of the insulation box 31;

[0080] A transmission torque rod 55, the axis of the inner cavity of the transmission torque rod 55 is fixedly connected to the outer surface of the output shaft of the pressing torque machine 54;

[0081] The threaded rotating rod 56, the outer surface of the threaded rotating rod 56 is threadedly connected to the inner wall of the threaded end sleeve 53, and the outer surface of the driving torsion rod 55 is inserted into the axial center of the inner wall of the threaded rotating rod 56 through the insertion slot;

[0082] The pressurizing frame 57, the number of the pressurizing frames 57 is two, and the pressurizing frame 57 is arranged at one end of the threaded rotating rod 56 away from the pressurizing torsion machine 54.

[0083] The pressurizing frame 57 includes:

[0084] The counterweight sliding plates 571, the number of the counterweight sliding plates 571 is two, an inner plate capable of heating the film body is arranged in the middle area of the counterweight sliding plates 571, and a pressure-sensitive alarm is installed in the inner cavity of the counterweight sliding plates 571. Both the front and rear sides of the outer surface of the counterweight sliding plates 571 are slidably connected to the inner wall of the container 51, preventing the counterweight sliding plates 571 from rotating self with the rotation of the threaded rotating rod 56 and being misaligned with the pressurized film body;

[0085] The docking sleeve 572, which is fixedly installed at the axial center of the outer surface of the counterweight sliding plate 571, and the inner wall of the docking sleeve 572 is rotatably connected to one end of the threaded rotating rod 56 away from the pressurizing torsion machine 54. A rotating ring adapted to the inner wall rotating groove of the docking sleeve 572 is arranged at the bottom position of the threaded rotating rod 56, ensuring the stability of the connection between the docking sleeve 572 and the threaded rotating rod 56 and enabling the docking sleeve 572 to rotate with the threaded rotating rod 56;

[0086] The sliding pressure plate 573, the outer surface of the sliding pressure plate 573 is slidably connected to the bottom of the inner cavity of the counterweight sliding plate 571, and the bottom end of the sliding pressure plate 573 extends to the outside of the counterweight sliding plate 571. The top of the sliding pressure plate 573 is fixedly connected to the inner cavity of the pressure-sensitive alarm through a pressure-sensitive spring. When the upper and lower sliding pressure plates 573 are butted and squeezed, they will gradually contract into the inside of the counterweight sliding plate 571, and then trigger the pressure-sensitive alarm through the pressure-sensitive spring. When the pressure received by the pressure-sensitive alarm reaches a certain threshold, an alarm sound will be emitted.

[0087] The docking box 1 includes:

[0088] The docking shell 11, the inner wall of the docking shell 11 is fixedly connected to the outer surface of the guiding sliding plate 21, the right side of the outer surface of the docking shell 11 is inserted into the left side of the outer surface of the heat preservation box 31, and jet grooves 12 are symmetrically opened on the right side of the inner wall of the docking shell 11;

[0089] The pressurizing plate 13, the outer surface of the pressurizing plate 13 is fixedly connected to the inner cavity of the docking shell 11, and the jet ports on both sides of the outer surface of the pressurizing plate 13 are communicated with the jet grooves 12;

[0090] The air suction plate 14, one side of the outer surface of the air suction plate 14 extends to the outside of the docking box 1, and the other side of the outer surface of the air suction plate 14 communicates with the inner cavity of the pressure plate 13. The pressure plate 13 directly sucks air from the outside through the air suction plate 14 to perform the air suction and pressurization work.

[0091] The laminated film body will be brought into the interior of the container 51 by the rotating guiding roller 52 in a rolling manner. Then, when the upper and lower pressure torsion machines 54 twist the threaded rotating rod 56 through the transmission torsion rod 55, the threaded rotating rod 56 will advance along the threaded groove of the threaded end sleeve 53 to the corresponding position of the pressure frame 57. At this time, the threaded rotating rod 56 gradually separates from the transmission torsion rod 55, but the transmission torsion rod 55 always inserts into the interior of the threaded rotating rod 56. The counterweight sliding plate 571 at the bottom of the threaded rotating rod 56 can only slide vertically and cannot rotate because it is restricted by the inner wall of the container 51. Therefore, the threaded rotating rod 56 rotates relative to the counterweight sliding plate 571 while advancing the counterweight sliding plate 571 to perform a vertical sliding movement.

[0092] During the docking process of the upper and lower counterweight sliding plates 571, they will directly heat the stacked film bodies and laminate the film bodies. Moreover, the sliding pressure plates 573 on both sides of the counterweight sliding plate 571 will squeeze each other after contact, thereby gradually pressing the pressure-sensitive alarm inside. When the film lamination is completed, the pressure-sensitive alarm inside the counterweight sliding plate 571 will also be triggered, thereby stopping the pressurization work, pulling the counterweight sliding plates 571 on both sides apart, and transporting the laminated film bodies out.

[0093] The film belt inside the film winding cylinder 25 always slides from left to right through the rolling friction force of the guiding roller 52. Therefore, when the film belt is drawn out from the inside of the film winding cylinder 25, the pressure plate 13 on the left side will continuously suck air from the outside through the air suction plate 14. The air filtered by the air suction plate 14 is ejected from the air jet groove 12, and it will blow the outer surface of the sliding film belt, thereby flattening the film belt and cleaning the outer surface of the film belt to ensure that the cast polypropylene film and the aluminum film at the sandwich part do not contain impurities and wrinkles during lamination.

[0094] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
