Description

Technical Field

[0001] The utility model belongs to the technical field of ITO waste recycling, and in particular relates to an ITO waste recycling device. Background Art

[0002] ITO film is a semiconductor transparent conductive film with high conductivity and high transmittance. It plays a vital role in today's display technology and optoelectronics fields.

[0003] ITO film is known for its low resistivity and high transmittance in the visible light region, which makes it an indispensable component in displays and other optical devices. Its manufacturing process includes electrochemical diffusion, high temperature and plasma spraying methods, which determine the quality and performance of the film. ITO film is widely used in liquid crystal displays, touch screens, solar cells and other optoelectronic devices.

[0004] A small amount of waste will be generated in the production process of ITO film. If these wastes are discarded directly, it will cause a great waste. Therefore, they are generally recycled and reused. Since many ITO films are composed of two layers of PET film protective films on the outer surface and a layer of ITO film in the center, if they are recycled directly, the scope of use is very small and they cannot be well utilized. The existing recycling devices generally crush the whole film for recycling. Although this recycling method is efficient, it does not separate the different materials of the film body, which leads to a mixed material after recycling. It can only be used as a basic material and can no longer be finely processed. The recovery rate is not high, which is not conducive to reducing costs. Utility Model Content

[0005] The utility model aims to provide an ITO waste recycling device, which can separate various materials of a film body and then recycle them, so that the materials are recycled accurately and various materials will not be mixed with each other, so that they can be re-processed, reduce material costs and improve the recovery rate.

[0030] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0031] like Figure 1-7 As shown, an ITO waste recycling device includes a bracket 1, a crushing box 2 fixedly mounted on the top surface of the bracket 1, a separation box 3 fixedly mounted on the top surface of the crushing box 2, and a preheating box 4 fixedly mounted on the top surface of the separation box 3;

[0032] Among them, the film body is preheated at high temperature through the preheating box 4, so that the internal adhesive layer is hot-melted at high temperature, thereby loosening the adhesion between the materials, and then enters the separation box 3 to separate the two layers of PET film on both sides of the film body from the ITO film in the middle, and finally enters the crushing box 2 for crushing and recovery.

[0033] See attached Figure 5 The top of the preheating box 4 is provided with a feed port 41, a feeding mechanism is provided in the feed port 41, and an electric heating plate 45 is fixedly installed on the inner wall of the preheating box 4. The film body can be placed through the feed port 41 and gradually preheated at high temperature by the electric heating plate 45, so that the internal adhesive layer is melted at high temperature and the bonding between the materials is loosened;

[0034] In order to stably deliver the film, rubber rollers 42 are symmetrically rotated and installed in the feed port 41, and the adjacent surfaces of the two groups of rubber rollers 42 are in contact with each other. A servo motor 43 is fixedly installed on the outer surface of the feed port 41 near the feed port 41. At the same time, the servo motor 43 is connected to one of the rubber rollers 42 through a coupling 44, and the two groups of rubber rollers 42 are connected through a gear group. The film is embedded between the two groups of rubber rollers 42. The servo motor 43 can be used to drive the two groups of rubber rollers 42 to rotate synchronously through the coupling 44 to gradually transmit the film to the inside of the preheating box 4, thereby ensuring the stability of film recovery;

[0035] In this embodiment, the preheating box 4 is in a conical bucket shape with an inner wall inclined downward. Two groups of electric heating plates 45 are provided and symmetrically attached to the inner wall of the preheating box 4, so that the film body can be gradually preheated at high temperature on both sides to ensure the stability of preheating.

[0036] See attached Figure 4A separation partition 31 is arranged inside the separation box 3 to separate it into three areas, which correspond to the three crushing areas inside the crushing box 2. Pneumatic suction cups 32 are symmetrically arranged on the top of the three areas of the separation box 3, and the pneumatic suction cups 32 are connected to the pneumatic generator through pipelines. At the same time, a slide rail 33 is fixedly installed on the inner wall of the separation box 3, and a slide plate 34 is slidably installed between the slide rails 33. By fixing the pneumatic suction cups 32 on the slide plate 34, the two groups of pneumatic suction cups 32 can slide relatively in the separation box 3, so that when adsorbing the two side surfaces of the film body, it is pulled to both sides, and the PET film on the surface of the film body after high-temperature preheating is separated;

[0037] In order to realize the automatic separation of the film body, a pushing cylinder 35 is fixedly installed on the side wall of the slide plate 34, and a pushing plate 36 is fixedly installed on the power output end of the pushing cylinder 35. The pushing plate 36 is fixedly connected to the end of the pneumatic suction cup 32. Therefore, when the film body is separated, the pushing cylinder 35 is used to push the pneumatic suction cup 32 to approach the film body from both sides and adhere to the film body. At the same time, the pushing cylinder 35 is retracted to pull the two layers of PET film on the outer surface to both sides to separate it from the ITO film.

[0038] See attached Figure 3 as well as Figure 6-7 A crushing roller 21 is cross-rotatably connected inside the crushing box 2, and side crushing teeth 22 are cross-fixedly installed between the inner wall of the crushing box 2 and the crushing roller 21;

[0039] Among them, in order to drive the crushing roller 21, a crushing motor 11 is fixedly installed on the top surface of the bracket 1, and the power output end of the crushing motor 11 is connected to a reducer 12. By connecting the power output end of the reducer 12 to one of the crushing rollers 21, and the two crushing rollers 21 that are engaged with each other are connected through a gear set, the crushing motor 11 can be used to synchronously drive the two crushing rollers 21 to rotate in opposite directions through the reducer 12 to crush the center area, and at the same time, the two groups of crushing rollers 21 can be rotated in the opposite direction to cooperate with the side crushing teeth 22 to crush the two side areas, thereby forming three crushing areas, and the center crushing and the two side crushing can be intermittently performed, so as to indirectly crush the ITO film, and then the pneumatic suction cup 32 can crush the PET film it adsorbs when it is put down.

[0040] See attached Figure 7 A storage box 13 is installed in the bracket 1 just below the crushing box 2. At the same time, an isolation plate 14 is provided in the storage box 13 to separate the storage box 13 into three areas, which correspond to the three areas in the separation box 3, so that the materials crushed in the three areas of the crushing box 2 can be received to avoid mixing after collection;

[0041] Furthermore, in order to ensure that the ITO film can fall to the center of the crushing box 2, the feed port 41 can be set directly above the occlusion center of the two sets of crushing rollers 21. At the same time, the inner empty area of ​​the crushing box 2 and the separation box 3 is the same, and they are vertically connected. In this way, when the film falls vertically, the ITO film can accurately fall between the two sets of crushing rollers 21, ensuring the stability of the crushing recovery and avoiding mixing of materials.

[0042] The working principle of the utility model is as follows: when in use, first, the film body is placed between two groups of rubber rollers 42, and at the same time, the servo motor 43 drives the two groups of rubber rollers 42 to rotate synchronously through the coupling 44 to gradually transfer the film body to the inside of the preheating box 4, and at the same time, the film body is baked at high temperature through the electric heating plate 45 during the transmission process, so that the bonding layer between the PET film and the ITO film is hot-melted at high temperature, thereby loosening the bonding between them;

[0043] Secondly, the film body enters the separation box 3, and at the same time, the push cylinder 35 pushes the pneumatic suction cup 32 to approach the film body from both sides and adhere to the film body, and at the same time, the push cylinder 35 is retracted to pull the two layers of PET film on the outer surface to both sides to separate it from the ITO film, so that the two layers of PET film and the ITO film in the middle enter the areas on both sides and the middle of the separation box 3 respectively;

[0044] Finally, the three layers of film respectively enter between the crushing rollers 21 and the side crushing teeth 22 on both sides and between the two groups of crushing rollers 21 in the middle. The materials in the middle and on both sides are crushed by intermittent reversal of the crushing motor 11. After being crushed, they enter the three isolation compartments of the storage box 13 respectively, which is convenient for classification and recycling.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
