Description

Technical Field

[0001] This utility model belongs to the field of sorting equipment technology, and in particular relates to a barrier fluorescence aging sorting device. Background Technology

[0002] Currently, in the plastic bottle recycling industry, bottle sorting equipment faces the technical challenge of effectively separating fluorescent-resistant aged bottles. Traditional sorting equipment mainly relies on manual visual sorting or simple optical identification technology, which cannot accurately distinguish between ordinary fluorescent-resistant aged bottles and aged bottles with fluorescent-resistant properties. Because fluorescent-resistant aged bottles do not produce obvious fluorescence under ultraviolet light, their optical characteristics are highly similar to those of ordinary plastic bottles, making it difficult for existing automated equipment to achieve accurate identification. Manual sorting is not only inefficient but also has a large fluctuation in sorting accuracy. This inefficient sorting process directly results in the downstream bottle flakes being mixed with a small amount of fluorescent-resistant aged bottle flakes, seriously affecting the purity and refining grade of recycled plastics. Utility Model Content

[0003] The purpose of this invention is to provide a fluorescent blocking aging sorting device, which aims to solve the technical problems of low accuracy and low production efficiency in sorting fluorescent blocking aging bottles in the prior art.

[0004] To achieve the above objectives, this utility model provides a fluorescence-blocking aging sorting device for screening fluorescence-blocking aging bottles and fluorescence-blocking aging bottles, including...

[0005] The base has a feeding and conveying mechanism on top of it. The output end of the feeding and conveying mechanism is connected to a spray valve mechanism. On the other side of the spray valve mechanism, a front hopper and a rear hopper are arranged in sequence.

[0006] The vision unit includes a support frame, a fluorescent lamp, and an identification cabinet. The support frame is connected to the base and is positioned above the feeding and conveying mechanism. The fluorescent lamp is installed inside the support frame, and the identification cabinet is located on one side of the fluorescent lamp. The identification cabinet is connected to an externally controlled industrial computer.

[0007] In this process, aging bottles enter the feeding and conveying mechanism, fluorescent aging bottles flow into the front hopper, and aging bottles that block fluorescence are identified by the vision unit and then blown to the rear hopper by the spray valve mechanism driven by the industrial control computer.

[0008] Furthermore, a closed protective frame is provided above the base, and the protective frame and the feeding and conveying mechanism form a conveying channel for transporting aging bottles; a chute opening is provided above the protective frame to connect with the conveying channel, and the aging bottles enter the conveying channel from the chute opening.

[0009] Furthermore, the upper end of the protective frame is composed of several parallel and detachable protective baffles, which are disposed between the chute opening and the supporting frame.

[0010] Furthermore, the identification cabinet includes a line scan camera identification cabinet and a dual-scan camera identification cabinet, which are arranged adjacent to each other and work together to identify aging bottles that block fluorescence.

[0011] Furthermore, a closed storage shell surrounds the front and rear material hoppers. Inside the storage shell, there is a bent guide plate. One end of the guide plate extends from the output end of the feeding and conveying mechanism to the top inner wall of the storage shell, preventing the fluorescent aging bottles from falling into the rear material hopper along the guide plate.

[0012] Furthermore, the feeding and conveying mechanism includes rollers, a feeding motor, and a conveyor belt. Rollers are respectively provided at both ends of the base, and the conveyor belt is provided between the two rollers. The feeding motor is located on the side of the base, and the feeding motor drives one of the rollers to rotate, thereby driving the conveyor belt to rotate.

[0013] Furthermore, the base is also provided with support rollers for support, which are located below the lowest end of the conveyor belt.

[0014] Furthermore, the outer wall of the support frame is provided with a control panel for starting or stopping the equipment or adjusting parameters.

[0015] The above-mentioned one or more technical solutions in the barrier fluorescence aging sorting device provided in this embodiment of the utility model have at least one of the following technical effects:

[0016] In this design, bottles to be sorted are uniformly conveyed by a feeding and conveying mechanism. As they pass under the support frame, fluorescent lamps illuminate the aging bottles, which reflect the light back to the identification cabinet. Parameters such as fluorescence spectrum, transmittance, and scattering are collected in real time and fed back to an external industrial control computer. After processing the information, the industrial control computer locates the coordinates of bottles that meet the fluorescence blocking characteristics. When the target bottle moves to the action area of ​​the spray valve mechanism, the corresponding solenoid valve is triggered to generate a directional airflow, precisely blowing the fluorescence-blocking aging bottles into the rear hopper. Ordinary aging bottles continue to fall into the front hopper due to inertia. The entire process is completed synchronously in a single conveying operation, eliminating the need for secondary sorting. This improves the accuracy of sorting fluorescence-blocking aging bottles and increases production efficiency. Attached Figure Description

[0029] In one embodiment of this utility model, a fluorescence-blocking aging sorting device is provided for screening fluorescence aging bottles and fluorescence-blocking aging bottles, including...

[0030] The base 100 has a feeding and conveying mechanism 200 on top of it. The output end of the feeding and conveying mechanism 200 is connected to a spray valve mechanism 300. The other side of the spray valve mechanism 300 is provided with a front hopper 150 and a rear hopper 160 in sequence.

[0031] The vision unit 400 includes a support frame 410, a fluorescent lamp 420, and an identification cabinet 430. The support frame 410 is connected to the base 100 and is positioned above the feeding and conveying mechanism 200. The fluorescent lamp 420 is installed inside the support frame 410, and the identification cabinet 430 is located on one side of the fluorescent lamp 420. The identification cabinet 430 is connected to an externally controlled industrial computer (not specified).

[0032] The aging bottles enter the feeding and conveying mechanism 200, the fluorescent aging bottles flow into the front hopper 150, and the fluorescent aging bottles are identified by the vision unit 400 and blown to the rear hopper 160 by the spray valve mechanism 300 driven by the industrial control computer.

[0033] Specifically, the bottles to be sorted are uniformly conveyed by the feeding and conveying mechanism 200. As they pass under the support frame 410, fluorescent lamps 420 illuminate the aging bottles, which reflect the light back to the identification cabinet 430. Parameters such as fluorescence spectrum, transmittance, and scattering are collected in real time and fed back to an external industrial control computer. After information processing, the industrial control computer locates the coordinates of bottles that meet the fluorescence blocking characteristics. When the target bottle moves to the action area of ​​the spray valve mechanism 300, the corresponding solenoid valve is triggered to generate a directional airflow, precisely blowing the fluorescence-blocking aging bottles into the rear hopper 160. Ordinary aging bottles continue to fall into the front hopper 150 due to inertia. The entire process is completed synchronously in a single conveying operation, eliminating the need for secondary sorting. This improves the accuracy of sorting fluorescence-blocking aging bottles and increases production efficiency.

[0034] Furthermore, a closed protective frame 110 is provided above the base 100. The protective frame 110 and the feeding and conveying mechanism 200 enclose a transport channel 120 for conveying aging bottles. A chute opening 130 is provided above the protective frame 110, connecting to the transport channel 120. The aging bottles enter the transport channel 120 through the chute opening 130. The aging bottles enter the closed transport channel 120 formed by the protective frame 110 and the feeding and conveying mechanism 200 through the chute opening 130, and are stably transported to the identification area by the conveyor belt 230. The protective frame 110 effectively blocks external ambient light interference, ensuring that the fluorescence identification process is not affected by external light sources, and also preventing the bottles from accidentally falling or shifting during transportation. The upper end of the protective frame 110 consists of several parallel and detachable protective baffles 111, which are positioned between the chute opening 130 and the supporting frame 410. Operators can flexibly adjust or remove the baffles to adapt to different feeding requirements, while also facilitating cleaning or replacement of components by maintenance personnel.

[0035] Furthermore, a linear scan camera identification cabinet 431 and a double-sided scan camera identification cabinet 432 work together to identify aging bottles that block fluorescence. The aging bottle is first illuminated by a fluorescent lamp 420, and the fluorescence reflected by the aging bottle is sent to the linear scan camera. The linear scan camera feeds back the information to the industrial control computer, and then the double-sided scan camera feeds back the information to the industrial control computer. The industrial control computer combines the information obtained from the two processes to obtain the result, and outputs it to the spray valve mechanism 300 for execution. The selected aging bottles are blown out to the rear hopper 160, and the unselected aging bottles flow to the front hopper 150. The linear scan camera and the double-sided scan camera each have different scanning areas. For example, the linear scan camera can capture the fluorescence characteristics of the side of the bottle in real time, while the double-sided scan camera can simultaneously capture images of the front and back of the bottle. The two work together to improve the recognition accuracy.

[0036] Furthermore, the spray valve mechanism 300 employs a pneumatic method, including an airflow generator and a directional flow guide. The airflow generator produces a controllable airflow based on signals from the identification mechanism, and the directional flow guide directs the airflow to the target aging bottle, causing it to deviate from its original conveying path and enter the downstream hopper. Alternatively, other mechanical methods can be used to convey the aging bottle to the downstream hopper, such as a mechanical lever or a pulse suction cup.

[0037] Furthermore, the front hopper 150 and the rear hopper 160 are separated by a partition plate 190. A closed storage housing 140 surrounds both the front and rear hoppers. Inside the storage housing 140, a bent guide plate 170 is provided. One end of the guide plate 170 extends from the output end of the feeding conveyor mechanism 200 to the top inner wall of the storage housing 140, allowing the fluorescent aging bottles to fall along the guide plate 170 into the rear hopper 160. The bent structure of the guide plate 170 cushions the impact of the falling bottles, preventing them from rebounding or piling up.

[0038] Furthermore, the feeding and conveying mechanism 200 includes rollers 210, a feeding motor 220, and a conveyor belt 230. Rollers 210 are respectively located at both ends of the base 100, and the conveyor belt 230 is positioned between the two rollers 210. The feeding motor 220 is located on the side of the base 100, and drives one of the rollers 210 to rotate, thereby rotating the conveyor belt 230. The base 100 also has support rollers 240, which are positioned below the lowest point of the conveyor belt 230. The feeding motor 220 drives the rollers 210 to rotate, thus driving the conveyor belt 230 to transport the aging bottles. The support rollers 240 are evenly distributed at the bottom of the conveyor belt 230 to prevent the bottles from sag or slipping due to the conveyor belt 230 sagging.

[0039] Furthermore, the outer wall of the support frame 410 is provided with a control panel 180 for starting or stopping the equipment or adjusting parameters.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
