Description

Technical Field

[0001] This utility model relates to the field of aluminum foil surface corona treatment technology, specifically to an aluminum foil surface corona treatment device. Background Technology

[0002] In practical applications, aluminum foil often needs to be laminated with materials such as paper and plastic, or used directly for printing. This places high demands on the wetting tension of the aluminum foil surface. If the wetting tension of the aluminum foil surface does not meet the standard, the adhesion of the protective agent and adhesive will be affected, leading to phenomena such as ink stripping. At the same time, it will also reduce the composite strength of aluminum foil with plastic and paper.

[0003] According to the authorized patent 'CN207596971U', an aluminum foil surface treatment device includes two parallel corona support plates. A first contact roller, a second contact roller, a lower corona device, and an upper corona device are mounted between the two corona support plates. The second contact roller is located to the left of the first contact roller, the lower corona device is located below the first contact roller, and the upper corona device is located above the second contact roller. The aluminum foil passes between the lower corona device and the first contact roller, and then between the upper corona device and the second contact roller. The lower corona device includes a connecting roller, a corona assembly fixed on the connecting roller, and a pushing mechanism for rotating the connecting roller. The upper corona device has the same structure as the lower corona device, and the installation direction of the upper corona device is symmetrical to the installation direction of the lower corona device. The pushing mechanism can change the distance between the corresponding corona assembly and the aluminum foil. This utility model has the functions of convenient aluminum foil installation and degreasing aluminum foil.

[0004] During the use of the above-mentioned technical solutions, although some improved devices have adjustment functions, the adjustment structure design is simple and mostly adopts a single guide adjustment method, which has problems such as low adjustment accuracy and poor stability. During the lifting and lowering process, it is easy to shake or deviate, which causes the distance between the corona cover and the aluminum foil surface to deviate, affecting the consistency of processing quality.

[0005] Therefore, a corona treatment device for aluminum foil surface is proposed to address the above problems. Utility Model Content

[0017] In terms of performance adjustment, the device is equipped with an adjustment mechanism that can flexibly adjust the position of the corona treatment components.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] A corona treatment device for aluminum foil surface includes an electrical control box 1 and a corona treatment mechanism 2. The corona treatment mechanism 2 includes a support plate 21, a feeding roller 22 and a winding roller 23 are arranged between the support plates 21, an mounting plate 24 is arranged on the inner side of the support plate 21, a fixing plate 25 is fixedly connected between the mounting plates 24, a starter 26 is arranged on the top of the fixing plate 25, a corona cover 27 is fixedly connected to the bottom of the starter 26, and an adjustment mechanism 3 is arranged on the outer side of the support plate 21.

[0029] The adjustment mechanism 3 includes a movable block 35, a slide rod 36 fixedly connected to the outside of the movable block 35, a lifting groove 37 opened inside the support plate 21, a slide groove 39 opened inside the other support plate 21, and a limit rod 38 fixedly connected to the outside of the mounting plate 24.

[0030] It should be noted that: a motor 31 is fixedly connected to the outer side of the support plate 21, a lead screw 32 is fixedly connected to the top output end of the motor 31, a collar 33 is threadedly connected to the outer side of the lead screw 32, and a connecting rod 34 is fixedly connected to the outer side of the collar 33.

[0031] Furthermore: support plates 21 are symmetrically distributed on the outside of the feeding roller 22 and the winding roller 23, with the winding roller 23 located directly above the feeding roller 22; mounting plates 24 are symmetrically distributed on the outside of the fixed plate 25; the starter 26 and the corona cover 27 are movably connected to the top of the winding roller 23 via the mounting plate 24; the moving block 35 is symmetrically and slidably connected on the outside of the support plate 21; the end of the slide rod 36 away from the moving block 35 is fixedly connected to the outside of the mounting plate 24; the end of the limiting rod 38 away from the mounting plate 24 is slidably connected to the inside of the slide groove 39; and the connecting rod 34 is symmetrically distributed on the outside of the collar 33, with the end of the connecting rod 34 away from the collar 33 fixedly connected to the outside of the moving block 35.

[0032] Specifically: The mounting plate 24 is symmetrically distributed on the outside of the fixing plate 25. Through the movable connection with the support plate 21, the corona treatment assembly consisting of the fixing plate 25, the starter 26 and the corona cover 27 is suspended directly above the winding drum 23. This suspended structure avoids direct contact with the transmission components and reduces mechanical interference. At the same time, the positional correspondence between the corona cover 27 and the winding drum 23 ensures that the aluminum foil can be corona treated before entering the winding drum 23, ensuring that the treated aluminum foil is wound up in time and avoiding secondary contamination.

[0033] Meanwhile, the starter 26 is installed on top of the fixed plate 25, and its bottom is fixedly connected to the corona cover 27, serving as the power source for the corona effect generated by the corona cover 27. When the control box 1 issues a start command, the starter 26 begins to run, providing the necessary energy to the corona cover 27 through its internal electrical components and mechanical structure, enabling it to generate a high-intensity electric field. The performance of the starter 26 directly affects the corona treatment effect. The stability and controllability of its output energy determine whether the corona intensity generated by the corona cover 27 is uniform and stable, thus affecting the treatment quality of the aluminum foil surface.

[0034] As a further implementation of this solution, a limiting buffer mechanism 4 is provided on the inner side of the support plate 21. The limiting buffer mechanism 4 includes a connecting plate 41, a movable tube 42 is fixedly connected to the top of the connecting plate 41, a nylon rod 43 is slidably engaged inside the movable tube 42, a force-bearing plate 44 is fixedly connected to the top of the nylon rod 43, and a shock-absorbing spring 45 is sleeved on the nylon rod 43.

[0035] It should be noted that the connecting plate 41 is fixed and symmetrically distributed on the inner side of the support plate 21, and the force plate 44 is located directly below the corona cover 27.

[0036] Furthermore, the nylon rod 43 possesses excellent wear resistance and toughness, reducing wear and extending service life during long-term sliding. The shock-absorbing spring 45 is fitted onto the nylon rod 43, with its two ends contacting the top of the movable tube 42 and the bottom of the force-bearing plate 44, respectively. When the force-bearing plate 44 is impacted by the aluminum foil, the spring's elastic deformation quickly absorbs energy, and the spring force can automatically adjust according to the magnitude of the impact, achieving flexible buffering and preventing damage to the aluminum foil from rigid contact. The force-bearing plate 44 is located directly below the corona cover 27, precisely at the critical position of the aluminum foil corona treatment, enabling it to function immediately upon any displacement of the aluminum foil, accurately aligning the buffer protection with the corona treatment area.

[0037] Workflow: In the aluminum foil conveying and corona treatment stage, the device continuously conveys aluminum foil through the feeding roller 22 and the winding roller 23. The aluminum foil enters from the feeding roller 22, passes through the conveying path between the two, and is finally wound up by the winding roller 23. When the electrical control box 1 is started, the starter 26 on the top of the fixed plate 25 starts to work, driving the corona cover 27 at the bottom to generate a corona effect, which corona treats the surface of the aluminum foil passing directly below it, improving the adhesion performance of the aluminum foil surface. Since the corona cover 27 is movably connected to the winding roller 23 directly above the mounting plate 24, and the winding roller 23 is located directly above the feeding roller 22, it is ensured that the aluminum foil is always within the effective range of corona treatment during the conveying process.

[0038] The operation of the adjustment mechanism 3 is the key to achieving precise corona treatment. When it is necessary to adjust the distance between the corona cover 27 and the aluminum foil surface according to the thickness and material of the aluminum foil, the motor 31 on the outside of the support plate 21 is started. The output end of the motor 31 drives the lead screw 32 to rotate. Since the lead screw 32 is threadedly connected to the collar 33, the collar 33 will move along the axial direction of the lead screw 32 and drive the moving block 35 to move synchronously through the symmetrically distributed connecting rods 34 on the outside. The sliding rod 36 on the outside of the moving block 35 slides in the lifting groove 37 of the support plate 21. At the same time, the limiting rod 38 on the outside of the mounting plate 24 slides in the sliding groove 39 of the support plate 21 on the other side. The two together restrict the movement trajectory of the mounting plate 24, so that the mounting plate 24 drives the fixed plate 25, the starter 26 and the corona cover 27 to rise and fall stably, thereby precisely adjusting the distance of corona treatment.

[0039] The limiting buffer mechanism 4 provides protection during the aluminum foil transmission process. When the aluminum foil experiences slight shaking or positional shift due to transmission fluctuations, the force plate 44 located directly below the corona cover 27 will be the first to contact the aluminum foil. The force on the force plate 44 is transmitted to the nylon rod 43 at the bottom, causing the nylon rod 43 to slide within the movable tube 42 at the top of the connecting plate 41. At the same time, the shock-absorbing spring 45 sleeved on the nylon rod 43 is compressed. The deformation of the shock-absorbing spring 45 generates a reverse elastic force, which can buffer the impact force of the aluminum foil and prevent the aluminum foil from wrinkling or breaking due to excessive instantaneous force, thus ensuring the stability of the corona treatment process.

[0040] In addition, the symmetrical distribution of the support plates 21 provides a stable installation foundation for the feeding roller 22, the winding roller 23 and various mechanisms, ensuring the balance and reliability of the overall structure during operation, and further improving the working efficiency and processing quality of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
