Description

Technical Field

[0001] The utility model relates to the technical field of screening, and particularly relates to a gas jet sorting device. Background Art

[0002] With the increasing global attention to environmental protection and sustainable development, the recycling and reuse of waste textiles have gradually become the focus of the industry and society. Due to the increasing scarcity of raw material resources and the sharp increase in the accumulation of waste textiles, it is particularly important to find effective ways for the recycling and reuse of waste textiles. The recycling and reuse process of waste textiles is complex and has high requirements for technology and equipment. Especially in this process, the sorting link, as the initial step, factors such as its accuracy, efficiency, energy consumption, and labor intensity all play a crucial role in achieving low-carbon and high-efficiency of the entire recycling process.

[0003] However, at present, the sorting of waste textiles mostly still relies on manual operation. This method has many drawbacks, such as high labor intensity, poor working environment, and even posing a potential threat to the physical health of workers. More importantly, the quality of manual sorting is often affected by individual subjective factors, making it difficult to ensure the accuracy and efficiency of sorting. Although Chinese Patent CN219971005U discloses a waste textile sorting device, which helps to effectively disperse the waste textiles stacked in a conical placement box through specific dispersion components. Unfortunately, this patent does not elaborate in detail on how to achieve precise sorting of waste textiles through specific mechanisms. This technical gap not only restricts the automation and intelligent level of waste textile sorting work but also restricts the efficiency and effect of the entire recycling and reuse process.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The present invention will be further described in conjunction with the drawings and embodiments:

[0021] As Figures 1-4 shown, a gas jet sorting device includes a conveying mechanism 1 for conveying waste textiles to be sorted. Side plates 21 are provided on both sides of the conveying mechanism. A front connecting plate 22 and a rear connecting plate 23 are provided between the two side plates. A driving mechanism 3 is provided at the top of the two side plates. An air jetting mechanism 4 is provided at the bottom of the conveying mechanism. A pressing mechanism 5 is provided on the front connecting plate. A supporting box 6 is provided on the rear connecting plate. Such a design makes the overall structure of the device compact, and the cooperation between components is smooth, effectively improving the sorting efficiency.

[0022] The solution is refined. The conveying mechanism includes a conveyor belt 11, and a number of ventilation holes 111 are provided on the conveyor belt. The design of the ventilation holes enables the gas jetted by the air jetting mechanism to smoothly pass through the conveyor belt, effectively blowing the waste textiles, and realizing the sorting of textiles based on weight.

[0023] Working mode: when the waste textiles are transmitted from the conveying mechanism to directly above the jetting mechanism, the jetting mechanism can eject gas through the ventilation holes so that the waste textiles are blown up by the air flow. If the waste textiles are heavy, they cannot be blown to lean against the driving mechanism, and the waste textiles will still be continuously conveyed forward by the conveying mechanism. When the waste textiles are light, they lean against the driving mechanism under the blowing of the air flow, and the driving mechanism makes the waste textiles enter the supporting box to complete the sorting work.

[0024] In at least one embodiment, the driving mechanism includes two parallel mounting plates 31. A number of support rods are provided between the two mounting plates. A driving wheel and a driven wheel are respectively rotatably connected to two ends of the mounting plate. The driving wheel and the driven wheel are drivingly connected by a synchronous belt 32. A number of teeth 33 are provided on the surface of the synchronous belt. A driving motor is provided on the mounting plate, and the output shaft of the driving motor is connected to the driving wheel. Through the design of the synchronous belt and the teeth, the driving mechanism can stably and accurately transmit the blown light waste textiles, ensuring the accuracy and reliability of the sorting process.

[0025] Furthermore, a first gap S1 for the teeth to pass through is left between the front connecting plate and the mounting plate, and a feeding port S2 for the waste textiles to pass through is left between the rear connecting plate and the mounting plate.

[0026] In at least one embodiment, the jetting mechanism 4 includes two lower connecting plates 42. The lower connecting plates are fixedly connected to the conveying mechanism by first bolts 43. The lower connecting plates are connected to lower vertical plates 41. An adjusting plate 45 is slidably fitted between the two lower vertical plates. A jack is provided on the adjusting plate, and a high-pressure nozzle 49 is installed in the jack and locked and fixed by a tightening knob 48. Through the design of the adjusting plate and the high-pressure nozzle, the jetting mechanism can flexibly adjust the jetting range and intensity to adapt to waste textiles of different weights and shapes, improving the flexibility and accuracy of sorting.

[0027] Furthermore, long holes are provided on the lower vertical plates. A connecting plate 44 is provided on one side of the long holes. Through holes are provided on the connecting plate, and second bolts 46 are installed in the through holes. The second bolts pass through the through holes and the long holes and are tightened and fixed by second nuts 47. The adjusting plate is fixedly connected between the two connecting plates. This structure enables the adjusting plate to stably slide on the lower vertical plates, facilitating precise adjustment of the jetting position, and at the same time ensuring the stability and durability of the jetting mechanism.

[0028] In at least one embodiment, the pressing mechanism includes a hinge seat 51 fixedly connected to the front connecting plate. A lower pressing plate 52 is rotatably connected to the hinge seat. The end of the lower pressing plate is arc-shaped. A first fixing plate 53 is provided on the front connecting plate. A vertical threaded rod 54 is slidably engaged with the first fixing plate. An upper pressing plate 55 is provided at the lower end of the vertical threaded rod. A flexible spring 56 is provided between the upper pressing plate and the lower pressing plate. A third nut 57 and a fourth nut 58 are threadedly connected to the vertical threaded rod. The third nut 57 and the fourth nut 58 are respectively on both sides of the first fixing plate. The pressing mechanism realizes the flexible pressing of waste textiles through the flexible spring and the adjustable vertical threaded rod, which not only avoids damaging the textiles but also ensures their smooth entry into the sorting process.

[0029] Further, the flexible spring urges the lower pressing plate away from the upper pressing plate.

[0030] Working mode, ensure that the conveying mechanism, jetting mechanism, driving mechanism and pressing mechanism are all correctly installed and debugged. Check whether each component is firm, especially key components such as high-pressure nozzles and synchronous belts. Ensure that power equipment such as the driving motor and jetting device can work normally.

[0031] Start the conveying mechanism to make it start to convey the waste textiles to be sorted. At the same time, start the jetting mechanism and the driving mechanism to prepare for the sorting work. When the waste textiles are conveyed to directly above the jetting mechanism by the conveyor belt, the jetting mechanism sprays gas through the high-pressure nozzles. The gas passes through the ventilation holes on the conveyor belt and acts on the waste textiles. According to the weight of the waste textiles, the light textiles will be blown up by the airflow, while the heavy textiles will continue to move forward on the conveyor belt. The blown-up light textiles lean against the synchronous belt of the driving mechanism under the action of the airflow. The driving motor drives the synchronous belt to move through the driving wheel, driving the light textiles to move backward. The light textiles enter the supporting box through the feeding port to complete the sorting.

[0032] According to actual needs, the range and intensity of jetting can be changed by adjusting the position of the adjusting plate in the jetting mechanism. Regularly check and clean the nozzles of the jetting mechanism to ensure the jetting effect.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
