[0035] Referring to Figures 1 to 5 An aluminum-plastic film forming device, which includes: a machine base 100, a film feeding device 200, a film forming device 300, a film pulling manipulator 400, and a slitting device 500. The film feeding device 200 is arranged on the machine base 100, the film forming device 300 is arranged on the machine base 100 and is located in front of the film feeding device 200, the film pulling manipulator 400 is arranged on the machine base 100 and is located in front of the film forming device 300, the film pulling manipulator 400 can move back and forth, and the slitting device 500 is arranged on the machine base 100 and is located in front of the film pulling manipulator 400. The slitting device 500 includes a transverse cutting mechanism 510, an intermediate longitudinal cutting mechanism 520, a front and rear driving assembly 530, and a cavity position sensor 540. The transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520 are arranged on the front and rear driving assembly 530, the intermediate longitudinal cutting mechanism 520 is arranged in front of the transverse cutting mechanism 510, the front and rear driving assembly 530 is used to drive the transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520 to move back and forth, the cavity position sensor 540 is arranged on the transverse cutting mechanism 510 and is used to detect the cavity position of the aluminum-plastic film, and the cavity position sensor 540 is electrically connected to the front and rear driving assembly 530 through a controller.

[0036] When the device works, the aluminum-plastic film is led out from the film feeding device 200 and enters the film forming device 300. When passing through the film forming device 300, cavities arranged side by side left and right are continuously punched on the aluminum-plastic film. Then, the film pulling manipulator 400 grabs the aluminum-plastic film and moves it to the slitting device 500. The slitting device 500 drives the transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520 to move back and forth through the front and rear driving assembly 530 for position adjustment. At the same time, the cavity position sensor 540 on the transverse cutting mechanism 510 detects the cavity position. The controller is used to control the front and rear driving assembly 530 after the cavity position sensor 540 detects the cavity position, so that it drives the transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520 to move a predetermined distance as a whole, so that the transverse cutting mechanism 510 is aligned with a predetermined position on one side of the cavity. Then, through the transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520, the two cavities arranged side by side left and right are slit out.

[0037] For the above-mentioned aluminum-plastic film forming equipment, after the die cavity of the aluminum-plastic film is formed, it can be pulled forward by the film pulling manipulator 400 to the slitting device 500 for horizontal and vertical slitting, thus avoiding the problem of poor slitting accuracy caused by unstable movement of the aluminum-plastic film due to prior intermediate slitting of the aluminum-plastic film. By setting the shell cavity position sensor 540, the position of the shell cavity can be detected. Cooperating with the horizontally cutting mechanism 510 and the intermediate vertical cutting mechanism 520 that can move back and forth, slitting at a predetermined position can be achieved, which is beneficial to further improving the slitting accuracy, making the size consistency of the slit products good and the qualification rate high.

[0038] In the embodiment, the film pulling manipulator 400 can pull a predetermined distance at one time, so that the aluminum-plastic film that needs to be stamped with the shell cavity enters the film forming device 300, and at the same time, the aluminum-plastic film with the shell cavity stamped is separated from the film forming device 300. Then the film pulling manipulator 400 resets. By continuously pulling and resetting, the aluminum-plastic film can be continuously moved forward.

[0039] In the embodiment, the film feeding device 200 includes a unwind roller 210 and an unwind motor 220. The output shafts of the unwind roller 210 and the unwind motor 220 are connected. The aluminum-plastic film coil can be installed on the unwind roller 210, and the unwind motor 220 drives the unwind roller 210 to rotate to unwind the aluminum-plastic film. The aluminum-plastic film is tensioned by the tension roller group 230 and then fed into the film forming device 300.

[0040] In the embodiment, the film forming device 300 is configured to punch a boss upward on the aluminum-plastic film to form a shell cavity, and the shell cavity position sensor 540 is configured as a height sensor facing the aluminum-plastic film. With the above structure, the position of the shell cavity can be detected by detecting the height by using the boss protruding upward from the shell cavity, and the structure is simple and easy to implement.

[0041] In an embodiment, the height sensor may be configured to output a high-level signal (or a low-level signal) when it is opposite to the boss formed on the aluminum-plastic film, and change to a low-level signal (or a high-level signal) when it is offset from the boss. Thus, through the mutation of the signal, the edge position of the shell cavity can be detected. The mutated electrical signal of the height sensor is used as a trigger signal and detected by the controller. After detecting the trigger signal, the controller controls the front and rear drive assemblies 530 to move a predetermined distance, so that the transverse cutting mechanism 510 and the intermediate longitudinal cutting mechanism 520 perform cutting at a predetermined position, ensuring the cutting accuracy. In the embodiment, the controller may specifically adopt a PLC, an industrial control computer, etc., and it may specifically be the control host of the device. The controller can perform corresponding control through simple level judgment, and those skilled in the art can implement it by adopting appropriate existing technologies according to the actual situation. Of course, the controller is not limited to adopting the above structure. For example, the controller can also adopt a combination of existing circuits: for example, a logic gate circuit is set to detect whether the signal of the height sensor mutates. After the signal of the height sensor mutates, the logic gate circuit provides a control level to the front and rear drive assemblies 530 to drive the corresponding components to act, and a timing circuit or an encoder is used to control the front and rear drive assemblies 530 to stop driving after completing the corresponding driving work.

[0042] In an embodiment, the film forming device 300 includes an upper clamping die 310, a lower clamping die 320, a film clamping driver 330, a stamping die 340, and a stamping die driver 350. The upper clamping die 310 and the lower clamping die 320 are arranged up and down. A passing position for the aluminum-plastic film is formed between the upper clamping die 310 and the lower clamping die 320. The film clamping driver 330 is used to drive the upper clamping die 310 and the lower clamping die 320 to close and open the mold. When the upper clamping die 310 and the lower clamping die 320 are closed, a concave cavity is formed. The stamping die 340 is provided with a stamping core, and the stamping core is adapted to be inserted into the concave cavity to stamp and form the shell cavity of the aluminum-plastic film. The stamping die driver 350 is used to drive the stamping die 340 to act, and the stamping die driver 350 is a servo drive structure.

[0043] During forming, the aluminum-plastic film is made to enter between the upper clamping die 310 and the lower clamping die 320. The film clamping driver drives the upper clamping die 310 and the lower clamping die 320 to approach each other to clamp and fix the aluminum-plastic film. Then, the stamping die driver 350 drives the stamping die 340 to act, so that it cooperates with the concave cavity to stamp and form the shell cavity on the aluminum-plastic film. After the shell cavity is formed, the stamping die 340 returns to its original position, and the upper clamping die 310 and the lower clamping die 320 return to their original positions. The film pulling manipulator 400 can pull the section of the aluminum-plastic film and continue to move forward for cutting. The stamping die driver 350 adopts a servo drive structure, which has better controllability, higher movement accuracy, and better shell cavity forming quality compared with using a cylinder.

[0044] In an embodiment, the stamping die driver 350 includes a servo motor 351 and a lead screw mechanism 352. The output shaft of the servo motor 351 drives the stamping die 340 to act through the lead screw mechanism 352. The servo motor 351 is easily obtained. The servo motor 351 drives the stamping die 340 to act through the lead screw mechanism 352, and the structure is simple. It can be imagined that the stamping die driver 350 can also adopt other servo drive structures, such as a servo linear motor and so on.

[0045] In an embodiment, the lower clamping die 320 is fixedly arranged on the machine base 100. Two through holes are formed in the lower clamping die 320. The upper clamping die 310 is arranged up and down movably on the lower clamping die 320 through guide posts. Two grooves are formed in the upper clamping die 310. The grooves and the through holes are vertically opposite one by one. When the upper clamping die 310 and the lower clamping die 320 are closed, the through holes and the grooves enclose to form the aforementioned cavity. The stamping die 340 is located on the lower side of the lower clamping die 320. The stamping core is opposite to the through holes and the grooves of the lower clamping die 320. The film clamping driver 330 is used to drive the upper clamping die 310 to press against the lower clamping die 320, and the stamping die driver 350 is used to drive the stamping die 340 to move up and down. When the stamping die driver 350 drives the stamping die 340 to move upward, the aluminum-plastic film can be stamped upward into the cavity, so as to form a shell cavity protruding upward, that is, the aforementioned boss. In an embodiment, the film clamping driver 330 can adopt a cylinder or an electric cylinder (such as an electric push rod) to drive the upper clamping die 310 to act.

[0046] It can be imagined that in other embodiments, the film forming device 300 is not specifically limited to the above implementation manner. In the art, there are many implementation manners for stamping the aluminum-plastic film to form a shell cavity. Those skilled in the art can specifically configure according to the actual situation.

The film pulling manipulator 400 is further provided with a clamping strip driver 450 for driving the two left clamping strips and the two right clamping strips to approach and separate from each other. With the above structure, through the arrangement of the left clamping strip group 410, the right clamping strip group 420 and the clamping strip driver 450, the left and right side edges of the aluminum-plastic film can be clamped along the length direction of the aluminum-plastic film, the aluminum-plastic film can be fixed more stably, and it is more stable during film pulling, which is beneficial to improving the subsequent slitting accuracy.

[0048] In an embodiment, the film pulling manipulator 400 further includes a first front-back moving seat 430.

The clamping strip driver 450 adopts a cylinder or an electric cylinder. The clamping strip driver 450 drives the upper left clamping strip and the upper right clamping strip to move up and down, so as to realize the function of clamping and releasing the aluminum-plastic film by the two left clamping strips and the two right clamping strips. Of course, it can be imagined that in some embodiments, each left clamping strip and right clamping strip can also be individually configured with a driver for driving, or the left clamping strip and the right clamping strip share a driver for driving, and specific configuration can be carried out according to the actual situation.

[0050] In an embodiment, the cross-cutting mechanism 510 is provided with a cross-cutting knife 511 arranged in the left-right direction, and the middle longitudinal cutting mechanism 520 is provided with a longitudinal cutting knife 521 arranged in the front-back direction.
