[0026] The terms "application" and "the application" as used herein are intended to refer broadly to all of the subject matter of this patent document. Statements containing these terms should be understood not to limit the subject matter described herein or to limit the meaning or scope of any patent claims below. Furthermore, the present application is not intended to be limited to any particular subject matter unless specifically recited in a claim. Moreover, the patentable scope of the application can include other actions and can be practiced or carried out in other ways than those specifically recited herein.
[0027] The details of the application will now be discussed with reference to the accompanying drawings, which are presented only by way of example and which must not be considered limiting in any way. In the drawings, similar features or components can be labeled using the same reference numerals.
[0028] The use of "including", "having" and "comprising" and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Although the terms above, below, up, down, rear, front, back, bottom, top, etc. can be used in this description to describe the orientation of features relative to the drawings, these terms are used for convenience and are not intended to be limiting as to the position of the features on the application. Also, terms such as "first", "second", "third", etc. are used herein for descriptive purposes and are not intended to connote or dictate importance or significance.
[0029] Referring to Figure 1, in a preferred embodiment, the novel multifunctional aluminum foil slitting machine of the present invention includes an unwinding mechanism 1, a personnel operating platform 2, a film slitting mechanism 3, and a winding mechanism 4 connected in sequence. The unwinding mechanism 1 includes a transfer pressing platform 5 and a correction mechanism 6. The correction mechanism 6 is located at the front end of the transfer pressing platform 5. With the assistance of personnel, the material film is corrected and pressed, and then sequentially undergoes film slitting, edge material recycling, and finally winding.
[0030] Referring to Figure 2, the transfer pressing platform 5 includes a carrying platform 7, a pressing block 8, and a pressing drive mechanism 9. The pressing block 8 is located on the material film movement path of the carrying platform 7, and the pressing drive mechanism 9 achieves the pressing of the material film. In actual production, after the material reaches the bottom of the shaft, it needs to be cut first, and then connected with the previous material after being replaced with new material. To facilitate actual operation, the transfer pressing platform 5 is designed in the film path. Since the film is in a free state after being cut, a pressing-related structure is designed to press the cut material.
[0031] Furthermore, the clamping blocks 8 are arranged in a group. As shown in Figure 3, a material dividing position 10 (cutting slit) is provided in the middle between the two clamping blocks 8 to facilitate precise cutting of materials on site.
[0032] Preferably, the clamping drive mechanism 9 is a first cylinder.
[0033] The correction mechanism 6 includes a set of photoelectric sensors, which are respectively located on the left and right sides of the material film moving path. They can detect the direction of material deviation (left or right). After the sensors acquire data, they transmit it to the control system, which then controls the electric cylinder to move and achieve correction.
[0034] The personnel operating platform 2 includes an extension mechanism, which enables the personnel operating platform 2 to be extended or retracted.
[0035] Preferably, the extension mechanism is a second cylinder, which is used to extend and retract the operating platform, making the most of the limited space.
[0036] Referring to Figures 4, 5, and 6, the film slitting mechanism 3 includes a slitting assembly 11, a wear measurement assembly 12, an edge material recycling assembly 13, and a roller 14 connected in sequence. This invention adds a roller wear detection function, which can reduce tension changes caused by roller wear, while significantly reducing personnel maintenance costs and material scrap rates. It also allows technicians to monitor equipment status at any time, greatly reducing equipment maintenance time.
[0037] Referring to Figure 7, the winding mechanism 4 includes a support platform 15, a swing arm 16, a swing arm drive assembly 17, and a rubber roller 18. One end of the swing arm 16 is rotatably connected to the support platform 15, and the other end is fixedly connected to an air shaft 19, on which a material cylinder is sleeved. The swing arm drive assembly 17 drives the swing arm 16 to swing, and the rubber roller 18 is located on the swing path of the swing arm 16. The swing of the swing arm 16 causes the material cylinder to reach the position of the rubber roller 18 and adhere tightly to it, maintaining a certain pressure. The advantage of the swing arm structure is that, in addition to fulfilling the winding function, it can simultaneously press and flatten the material while winding the film, ensuring winding quality, reducing wrinkles, and providing a strong guarantee for the pass rate of subsequent processes.
[0038] Preferably, the swing arm drive assembly 17 is a third cylinder.
[0039] After the material cylinder in the winding mechanism 4 is mounted on the air shaft 19, a command is given to the third cylinder to retract it. Once the third cylinder reaches its position, the material cylinder will press tightly against the rubber roller 18, maintaining a certain pressure under the action of air pressure. During this process, the pressure of the rubber roller 18 on the material is the same whether the shaft is empty or full, thus minimizing the impact of empty or full shafts on the product.
[0040] The dashed line in Figure 1 represents the film feeding path. This equipment optimizes the film feeding route to minimize the film feeding length and simplify the equipment structure. In actual operation, the material is loaded on the unwinding side, and the film is threaded through according to the film feeding path, then fixed to the take-up air shaft. Next:
[0041] a. Load the material film, then pass the material film through the roller and position it in the middle of the photoelectric sensor. First, visually adjust the unwinding to the middle position, pass it through the transfer command pressing platform 5, and then give the first cylinder a retraction command to press the material film through the pressure block.
[0042] b. When inserting the membrane, the personnel operating platform 2 needs to be in the retracted state to facilitate the insertion. After the membrane is inserted, give the second cylinder a command to unfold the platform.
[0043] c. Pass the material film sequentially through the slitting assembly 11, the edge material recycling assembly 13, and the roller 14. The roller 14 requires periodic wear detection. The specific detection steps are as follows: After the film is passed through, set the detection parameters, start the wear measurement command, carefully read the equipment prompts, and proceed to the next step as required (if the roller is within the wear range, no maintenance is needed, or the roller needs maintenance).
[0044] d. Give the third cylinder an extension command, and the swing arm 16 moves outward to fix the material film on the upper and lower air expansion shafts respectively, straighten and fix it, give the third cylinder a retraction command, and tighten the film.
[0045] e. Start the device.
[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
