Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a device for identifying aging of plastic bottles. Background Art

[0002] With the rapid development of industry, the application of plastic products has spread to all areas of daily life, but it also brings about a large amount of plastic waste that pollutes the environment. Therefore, it is necessary to recycle and reuse discarded plastic products to reduce pollution to the environment and turn waste into treasure.

[0003] For example, when recycling common plastic bottles in our daily life, the aged bottles need to be removed. This is because the discarded plastic bottles are exposed to the outside for a long time, and the polymer macromolecules in the plastic are affected by environmental factors, causing chemical phenomena such as molecular chain breakage, molecular weight reduction or macromolecular structure change, which reduces the physical properties of the plastic and causes the aged plastic bottles to lose their use value. Since the aged plastic bottles will fade and turn yellow, they are generally screened manually in the prior art. However, some plastic bottles are less aged, the fading is not obvious, the recognition is not high, and they are difficult to identify with the naked eye. It is easy to make mistakes or miss selections during manual screening, which will affect the quality of the finished product after processing. Utility Model Content

DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] In order to solve the above technical problems, the present application provides a plastic bottle aging identification device.

[0021] See also Figure 1A plastic bottle aging identification device comprises: a conveyor belt device 1, a mounting frame 2, and an identification device 3; the conveyor belt device 1 is used to convey the plastic bottles; the mounting frame 2 is mounted on the conveyor belt device 1; the identification device 3 is arranged in the mounting frame; the identification device 3 comprises: an ultraviolet lamp 31; the light of the ultraviolet lamp 31 is emitted in a direction toward the conveyor belt device 1.

[0022] In the specific implementation process, the identification device 3 is mounted on the conveyor device 1 through the mounting frame 2. When the conveyor device 1 transports plastic bottles, the plastic bottles will pass through the identification device 3. The identification device 3 emits a large amount of ultraviolet rays to the plastic bottles on the conveyor device 1 through the ultraviolet lamp 31. As the plastic bottles age, their internal molecular structure changes. After being irradiated with ultraviolet rays, the color of the aged plastic bottles changes significantly, thereby improving the recognition of the aged bottles. Workers can easily screen them out, effectively reducing the probability of wrong selection or missed selection, and ensuring the quality of the finished product after processing. At the same time, through the coordinated use with the conveyor device 1, the effect of semi-automatic screening is achieved, which improves work efficiency and reduces labor intensity.

[0023] It should be noted that the conveyor belt device 1 is a prior art and is not specifically described herein. In addition, in order to prevent the ultraviolet light from causing harm to the human body, ultraviolet protection clothing should be worn during operation to ensure life safety.

[0024] See also Figure 2 In the specific implementation process, the mounting frame 2 is provided with a support rod 22; a connecting mechanism 23 is provided at one end of the support rod 22 close to the ground for connecting with the conveyor device 1. The mounting frame 2 is detachably connected with the conveyor device 1 through the connecting mechanism 23 on the support rod 22, so that the mounting frame 2 can be installed on the conveyor device 1 in the production line, so that it has an identification function, and the aged plastic bottles can be manually removed during the transportation process without opening a special production line, saving the production cost.

[0025] It should be noted that the number and position of the support rods 22 are not specifically limited, as long as the mounting frame 2 can be connected to the conveyor belt device 1. In the present embodiment, the number of the support rods 22 is four, which are distributed in a rectangular shape around the mounting frame 2. Through this design, the mounting frame 2 can be stably mounted on the conveyor belt device 1, the force is more evenly distributed, and the stability of the structure after connection is stronger.

[0026] See also Figure 3In the specific implementation process, the connection mechanism 23 includes: a base 231, a fastening screw 232; a mounting groove 2311 is provided on the side of the base 231 close to the ground; the mounting groove 2311 is clamped on the wall panels on both sides of the conveyor belt device 1; a threaded hole 2312 is provided on one side of the base 231; the fastening screw 232 cooperates with the threaded hole 2312 to fix the mounting frame 2 and the conveyor belt device 1. Through the base 231 in the connection mechanism 23, the mounting frame 2 can be quickly and stably mounted on the wall panels on both sides of the conveyor belt device 1, the operation is simple, and no manual support is required after the mounting, which reduces the labor intensity during the installation process; and the fastening screw 232 is tightened in the threaded hole 2312, so that the fastening screw 232 squeezes the side wall of the conveyor belt device 1 in the mounting groove 2311, and the mounting frame 2 can be firmly connected to the conveyor belt device 1. In addition, the mounting frame 2 is also provided with a sunshade net 21, which is covered outside the mounting frame 2, so that the inside of the mounting frame 2 can maintain a relatively dark environment, reduce the interference of external light sources, and make plastic bottles more obvious to identify; at the same time, the sunshade net 21 is also conducive to air circulation, ensuring the ventilation effect of the working environment of the staff, not stuffy, and low cost.

[0027] See also Figure 4 In the specific implementation stage, the identification device also includes: a fixing plate 32, the fixing plate 32 is connected to the ultraviolet lamp 31; the fixing plate 32 is fixedly connected to the mounting frame 2, and the fixing plate 32 is provided with a reflecting plate 321, and the reflecting plate 321 reflects the light of the ultraviolet lamp 31 onto the conveyor belt device 1; the ultraviolet lamp 31 is connected to the mounting frame 2 through the fixing plate 32, and the reflecting plate 321 on the fixing plate 32 reflects the light emitted by the ultraviolet lamp 31 onto the conveyor belt device 1, thereby enhancing the light intensity on the plastic bottles. After the aged plastic bottles are irradiated by the ultraviolet lamp 31, the color change will be more obvious, further improving the identification effect; at the same time, it can also avoid direct exposure of ultraviolet rays to the human body, further ensuring life safety. In addition, since the sheath of the power cord of the ultraviolet lamp 31 is made of plastic material, it will age faster after being exposed to ultraviolet rays for a long time, and will break or fall off after the performance is reduced, which is easy to cause a fire and has a great safety hazard. Therefore, the identification device 3 also includes: a protective tube 33; the protective tube 33 is set on the power cord of the ultraviolet lamp 31 to isolate ultraviolet rays, protect the power cord, avoid ultraviolet radiation, extend the service life of the power cord, and improve the safety during the production process. In addition, a tube clamp 322 for fixing the protective tube 33 is provided on the fixing plate 32, and the protective tube 33 is clamped and fixed to the fixing plate 32 to prevent the protective tube 33 from swinging back and forth around the ultraviolet lamp 31 during the production process, and the light shadow generated interferes with the workers' vision.

[0028] See also Figure 1In the specific implementation stage, a hook 11 is provided on the side wall of the conveyor belt device 1 for installing a collection bag; when manually screening aged plastic bottles, the collection bag can be hung on the conveyor belt device 1 through the hook 11, so that the rejected aged plastic bottles can be collected and processed uniformly, so as to maintain a clean working environment on site.
