DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying drawings Figures 1-7 The application is further described in detail.

[0038] The embodiment of the application discloses a positioning adjustment device and method for an aluminum foil precision slitting machine. Figures 1-7 A positioning adjustment device for an aluminum foil precision slitting machine, comprising an adjustment shaft 1 and a cutting mechanism 2 mounted on the adjustment shaft 1, the cutting mechanism 2 mainly comprising a knife seat 21, a drive shaft 23 mounted on the knife seat 21 and a blade 24 mounted on the outer surface of the drive shaft 23, the knife seat 21 is sleeved on the outside of the adjustment shaft 1, and a positioning adjustment ring 26 fixed with the adjustment shaft 1 is mounted on the outside of the knife seat 21; wherein the positioning adjustment ring 26 is internally provided with locking bolts or a quick locking mechanism; it should be noted that the quick locking mechanism can adopt any existing quick locking mode; wherein the outer surfaces of the adjustment shaft 1 and the positioning adjustment ring 26 can be provided with scale lines, in use, the adjustment shaft 1 provides a stable mounting basis and rotation or movement guide for the entire cutting mechanism 2. It ensures that the knife seat 21 can be adjusted in position on a specific trajectory, thereby meeting the requirements of different positions of the blade 24 in the aluminum foil slitting process, to adapt to the slitting requirements of aluminum foils of different specifications.

[0039] Specifically, the outer shape of the knife seat 21 is in the shape of a convex character, and the convex character-shaped outer shape design enables the knife seat 21 to better disperse stress when subjected to force. During the aluminum foil slitting process, the knife seat 21 will bear the reaction force generated when the blade 24 cuts the aluminum foil, as well as the vibration and torque brought by the rotation of the driving shaft 23. The convex character-shaped structure can avoid stress concentration, reduce the risk of cracks or fractures of the knife seat 21, improve the service life and reliability of the knife seat 21, and improve the slitting precision; the inside of the knife seat 21 is provided with a containing groove 22 and a mounting groove 25, and the containing groove 22 and the mounting groove 25 are communicated, and the blade 24 is located in the containing groove 22.

[0040] In order to provide cutting effect, the knife seat 21 is provided with a blow structure 3 and a cleaning mechanism 4 for cleaning the blade 24, which can effectively remove the aluminum foil debris, impurities and the like attached to the surface of the blade 24. If these debris and impurities remain on the blade 24, they will affect the contact between the blade 24 and the aluminum foil during the cutting process, resulting in uneven cutting edges, burrs and other problems. Through cleaning, the cutting precision of the blade 24 is ensured, the cutting of the aluminum foil is more smooth and regular, and the quality of the product is improved;

[0041] It should be noted that timely cleaning of the blade 24 can reduce the wear of the blade 24 caused by debris; since the aluminum foil debris may cause wear to the blade edge of the blade 24 during high-speed rotation and cutting of the blade 24, long-term accumulation may cause the blade 24 to become blunt, affecting the cutting effect and shortening the service life of the blade 24. The use of the cleaning mechanism 4 and the blow structure 3 reduces the degree of wear of the blade 24, thereby prolonging the service life of the blade 24 and even the entire cutting mechanism 2, reducing the maintenance cost of the equipment, and the cleaned blade 24 can maintain high cutting efficiency, reducing problems such as cutting speed reduction and cutting interruption caused by clogging or wear of the blade 24. The equipment can continuously and stably perform aluminum foil slitting operation, improve production efficiency, and meet the needs of production;

[0042] In addition, the guide seat 21 can be provided with a dust collection device or a dust collection pipe connected to the dust collection device, which can collect and process the dust after cleaning.

[0043] The cleaning mechanism 4 comprises a cleaning assembly 41 and an adjusting assembly 42, and a linkage assembly 43 is arranged between the cleaning assembly 41 and the adjusting assembly 42, and a synchronous part 32 is arranged between the blowing structure 3 and the adjusting assembly 42; specifically, the cleaning assembly 41 comprises two cleaning plates 411, and the two cleaning plates 411 are symmetrically distributed on both sides of the blade 24; meanwhile, the blowing structure 3 comprises a fan 31 mounted on the outer wall of the blade seat 21, and the fan 31 is externally provided with a shielding shell; the synchronous part 32 comprises two synchronous wheels 321, and the two synchronous wheels 321 are drivingly connected with a synchronous belt 322, one of the synchronous wheels 321 is internally provided with a synchronous shaft fixed with the outer wall of the fan 31, the other synchronous wheel 321 is connected with the adjusting assembly 42, and the outer wall of the fan 31 is provided with a gas conveying pipe 33 connected with the cleaning plate 411.

[0044] The adjusting assembly 42 in the embodiment comprises a transmission seat 421, a rotor 422 arranged in the transmission seat 421, and a centrifugal block 426 arranged outside the rotor 422, the transmission seat 421 is hollow, the rotor 422 is located on the inner side of the transmission seat 421, and the transmission seat 421 is rotatably mounted on the outer wall of the blade seat 21, and the other synchronous wheel 321 is mounted on the outer surface of the transmission seat 421.

[0045] Specifically, the adjusting assembly 42 further comprises an elastic guide 427 mounted between the centrifugal block 426 and the rotor 422, the end of the driving shaft 23 penetrates the inside of the rotor 422, and the outside of the rotor 422 is further provided with a rotating sleeve 423 and a sliding sleeve 424 sleeved on the outer surface of the driving shaft 23, wherein the rotating sleeve 423 and the sliding sleeve 424 are rotatably connected on one side, and the rotating sleeve 423 is rotatably connected with the outer surface of the driving shaft 23; the rotating sleeve 423 is hingedly connected with a pushing arm 428 between the centrifugal block 426. It should be noted that the elastic guide 427 is composed of a limiting rod and a spring, and the number of the centrifugal block 426, the elastic guide 427 and the pushing arm 428 is at least two, wherein the outer surface of the centrifugal block 426 is provided with an anti-skid pad abutting against the inner side of the transmission seat 421.

[0046] It should be noted that when the driving shaft 23 rotates, the rotor 422 is driven to rotate, and the centrifugal block 426 moves outward under the action of centrifugal force. The elastic guide 427 is composed of a limiting rod and a spring, which can buffer and limit the movement of the centrifugal block 426 to prevent the centrifugal block 426 from moving too much; the application utilizes the principle of centrifugal force to automatically adjust the position of the centrifugal block 426 according to the rotating speed of the driving shaft 23, so as to realize the dynamic adjustment of the working state of the cleaning mechanism 4; for example, when the rotating speed of the driving shaft 23 increases, the centrifugal force increases, the centrifugal block 426 moves outward more, and a stronger cleaning action is triggered; on the contrary, when the rotating speed decreases, the cleaning action is relatively weakened, and through the self-adaptive adjustment mode, the cleaning intensity can be flexibly adjusted according to the actual cutting condition, thereby improving the pertinence and effectiveness of the cleaning;

[0047] The linkage assembly 43 in this embodiment includes a connecting piece connected with the adjusting assembly 42 and a sliding plate 432, a connecting arm two 433 is arranged between the connecting piece and the sliding plate 432, a guide groove 434 is arranged in the sliding plate 432, a guide wheel 435 is rotatably connected in the guide groove 434, a connecting shaft 436 is rotatably connected in the guide wheel 435, and a connecting plate 437 fixed with the cleaning plate 411 is mounted at the end of the connecting shaft 436; wherein the connecting piece includes a sliding seat 431, one side of the sliding seat 431 is hingedly connected with the end of the connecting arm two 433, and a connecting arm one 425 connected with the sliding seat 431 is mounted on the outer surface of the sliding sleeve 424.

[0048] The cleaning assembly 41 further includes a guide rod 412 fixed to the inner wall of the opposite side of the containing groove 22, the guide rod 412 penetrates through the inside of the two cleaning plates 411, and a reset spring one 413 is mounted between the outer wall of the two cleaning plates 411 and the inner wall of the containing groove 22; in use, the guide rod 412 provides stable guidance for the movement of the cleaning plate 411, ensures that the cleaning plate 411 will not deviate during the movement process, and can accurately contact the blade 24 for cleaning, and the reset spring one 413 is mounted between the outer wall of the two cleaning plates 411 and the inner wall of the containing groove 22, so that the cleaning plate 411 can be automatically reset after completing the cleaning action, and the next cleaning is prepared, thereby improving the automation degree and working efficiency of the cleaning mechanism 4.

[0049] The inner wall of the mounting groove 25 is mounted with a guide rail 44, the sliding plate 432 is slidingly connected with the guide rail 44, the guide rail 44 provides accurate guidance for the movement of the sliding plate 432, ensures the stability and straightness of the sliding plate 432 during the movement process, thereby ensuring that the cleaning plate 411 can accurately move according to the predetermined track, and improving the working precision of the cleaning mechanism 4; specifically, the number of guide grooves 434 is two, and the two guide grooves 434 are symmetrically arranged in an inclined shape; when the sliding plate 432 moves, the guide wheel 435 rolls in the guide groove 434; due to the inclined design of the guide groove 434, the guide wheel 435 drives the connecting plate 437 and the cleaning plate 411 to make a specific linear motion, thereby achieving the cleaning of the blade 24.

[0050] In order to improve the movement effect of the sliding plate 432, a lubricating structure 5 is arranged on the top side of the sliding plate 432 and cooperates with the adjusting assembly 42; the lubricating structure 5 includes a pump cylinder 51 fixed to the inner top wall of the mounting groove 25, a piston block 52 fixed to the top side of the sliding plate 432 is slidingly arranged in the pump cylinder 51, a reset spring two 53 is mounted between the top side of the sliding plate 432 and the bottom side of the pump cylinder 51, two check valves 54 are mounted on the outer wall of the pump cylinder 51, and one end of each of the two check valves 54 is mounted with a liquid delivery pipe 55, and the liquid outlet end of one of the liquid delivery pipes 55 faces the guide rail 44.

[0051] It should be noted that the infusion pipe 55 connected to the guide rail 44 can be a flexible hose; a liquid storage tank is installed inside the cutter holder 21, and another infusion pipe 55 is connected to the liquid storage tank; due to the friction between the slide plate 432 and the guide rail 44 during movement, the lubrication structure 5, through the cooperation of components such as the pump cylinder 51 and the piston block 52, delivers the lubricating fluid from the liquid storage tank to the surface of the guide rail 44 when the slide plate 432 moves. The lubricating fluid forms a lubricating film between the guide rail 44 and the slide plate 432, reducing the direct contact and friction between the two, making the movement of the slide plate 432 smoother, avoiding problems such as jamming and jumping caused by friction, thereby improving the accuracy and stability of the movement of the slide plate 432; moreover, a good lubrication environment helps to reduce vibration and noise during equipment operation. The improved smoothness of the movement of the slide plate 432 reduces abnormal vibration caused by friction and wear, making the operation of the entire cutting mechanism 2 more stable. This not only improves the cutting quality but also reduces damage to other parts of the equipment caused by vibration, improving the overall reliability of the equipment.

[0052] Another problem that this invention also needs to solve is to provide a positioning adjustment method for a precision aluminum foil slitting machine, comprising the following steps:

[0053] S1. Preparation and safety confirmation: First, stop the machine and ensure that the main power supply of the equipment is turned off. Then clean the area of ​​adjusting shaft 1 and tool holder 21 to prevent foreign objects from affecting the positioning accuracy.

[0054] S2. Loosen the locking mechanism, then loosen the fasteners that fix the tool holder to the adjusting shaft, usually screws or quick-locking mechanisms. Next, perform coarse adjustment and precise positioning. Using the scale on the adjusting shaft 1 or a fixed reference tool holder 21 as a reference, manually slide the tool holder 21 along the adjusting shaft 1 until the indicator mark on it is aligned with the corresponding scale on the positioning adjusting ring 26. Since the positioning adjusting ring 26 is fixed on the adjusting shaft 1, it provides a precise width positioning reference.

[0055] S3. Locking and fixing: Finally, tighten the locking mechanism of the tool holder 21 to ensure that the tool holder 21 and the adjusting shaft 1 are firmly connected and will not shift during high-speed operation;

[0056] Specifically, after completing the initial positioning of all blades 24, check whether the relative positions between the blades 24 meet the slitting width requirements; if necessary, they can be loosened for fine-tuning. For higher-end models, this step may be completed through sensors and automated systems.

[0057] Combined with appendix Figures 1-7 The working principle of the above embodiments is as follows:

[0058] When the aluminum foil precision cutting machine works, firstly the driving shaft 23 starts to rotate, driving the blade 24 installed on its outer surface to rotate, cutting the aluminum foil, at the same time, the adjusting assembly 42 works, when the driving shaft 23 rotates, the rotor 422 in the adjusting assembly 42 rotates, at this time, the centrifugal block 426 outside the rotor 422 moves outward under the action of centrifugal force, overcoming the elastic force of the elastic guide 427, the centrifugal block 426 pushes the sliding sleeve 424 to move close to the rotor 422 through the pushing arm 428, the sliding sleeve 424 drives the sliding seat 431 to move through the connecting arm one 425;

[0059] The sliding seat 431 drives the sliding plate 432 to slide on the guide rail 44 through the connecting arm two 433, because the guide groove 434 inside the sliding plate 432 is inclined, the guide wheel 435 rolls in the guide groove 434, driving the connecting shaft 436 and the connecting plate 437 to move, and then making the two cleaning plates 411 symmetrically distributed on both sides of the blade 24 move along the guide rod 412, cleaning the rotating blade 24;

[0060] In addition, the fan 31 in the blowing structure 3 is linked with the adjusting assembly 42 through the synchronous part 32, when the adjusting assembly 42 works, driving the synchronous wheel 321 to rotate, and then making the fan 31 work, blowing air to the cleaning plate 411 through the air conveying pipe 33, assisting in cleaning the blade 24.

[0061] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape and principle of the present application should be covered in the protection scope of the present application.
