Description

Technical Field

[0001] The utility model relates to an executive mechanism for sorting waste textiles, which is used for sorting out the classified waste textiles. Background Art

[0002] With the improvement of the material and cultural living standards of the people, residents have a strong demand for food, clothing and daily necessities. Clothes represent a person's external image and must be comfortable, fit and fashionable. Therefore, clothing and other wearable textile products are updated very quickly, and many discarded clothes are discarded at will, either left alone or thrown away as garbage. Those left alone are generally likely to be thrown away, and these discarded waste textiles still have considerable use value. If they are burned or buried as garbage, it will not only cause a huge waste of resources, but also cause environmental pollution.

[0003] The recycling of waste textiles plays a vital role in resource conservation and environmental protection, yet my country's recycling of waste textiles is still in its infancy. Currently, society has gained a new understanding of the value of recycling waste textiles, and the recycling of waste textiles is an inevitable trend with promising prospects.

[0004] Because textiles come in many varieties, with different colors and raw materials, the directions of recycling are also different. Therefore, the current classification and sorting technology of textiles has become the basic premise for textile recycling. The color, composition and other characteristics of waste textiles determine the choice of reuse method and the level of reuse added value. The core of waste textile sorting is identification, which includes manual identification and sorting and mechanical identification and sorting. Manual identification and sorting uses human perception to identify and classify, which is inefficient, and some raw materials cannot be identified; mechanical identification and sorting uses near-infrared spectroscopy technology and imaging technology to identify components and colors, which has the advantages of high efficiency, speed and non-destructiveness. The commercial utilization of waste textile recycling can only rely on automatic identification and mechanical identification and sorting.

[0005] Currently, there is no mature, reliable sorting and classification equipment. Although my country, as a major e-commerce country, has a large number of automatic sorting equipment used in logistics, existing logistics sorting equipment is not suitable for direct application in sorting waste textiles. In China, a Shanghai Environmental Protection Technology Co., Ltd. and a Beijing Fashion Institute collaborated to develop a drop-bag sorting system using near-infrared technology. However, this system was hastily discontinued due to the immaturity of the drop-bag actuator and lack of market acceptance. Furthermore, because waste textiles are unpackaged, scattered, contain a high concentration of short fibers, and have a large weight difference, the actuator using an air-blowing mechanism cannot blow away heavy waste textiles. The drop-bag structure also suffers from problems such as loose sealing, material slippage, and uncertain drop time, which can easily lead to clamping.

[0006] In order to solve the problem that the existing air blowing and pushing plates are not suitable for sorting waste textiles and overcome the functional defects of the existing actuators that are not suitable for sorting textiles, it is necessary to design a sorting mechanism and device suitable for sorting waste textiles. Utility Model Content

[0007] In response to the shortcomings of the existing technology, the utility model proposes a combined actuator suitable for sorting waste textiles. The nozzle blowing and pneumatic push plate complement each other. For textiles with relatively light weight, the air blowing method can be used to pick them out, and for textiles with relatively heavy weight, the push plate can be used to push them out to achieve classification and sorting.

[0008] The technical solution adopted by this utility model:

[0009] A combined actuator for waste textile sorting equipment is designed, including a nozzle blowing mechanism and a pneumatic push plate mechanism. The power of the nozzle blowing mechanism and the pneumatic push plate mechanism adopts a pneumatic system; the nozzle blowing mechanism includes a blowing control solenoid valve and a nozzle, the air inlet of the blowing control solenoid valve is connected to the air source, and the air outlet of the blowing control solenoid valve is connected to the nozzle; the pneumatic push plate mechanism includes a push plate, an actuator cylinder and an electromagnetic reversing valve, the air inlet of the electromagnetic reversing valve is connected to the air source, the air outlet of the electromagnetic reversing valve is connected to the cylinder, and the front end of the cylinder push rod is connected to the push plate.

[0010] The combined actuator of the waste textile sorting equipment and the pneumatic push plate mechanism are provided with quick exhaust valves in the gas circuits at both ends of the actuator cylinder.

[0011] The nozzle of the nozzle blowing mechanism and the cylinder of the pneumatic push plate mechanism are fixed on the wall panel at the conveyor curtain sorting grid of the sorting equipment; the blowing control solenoid valve and the solenoid reversing valve are controllably connected to the control unit of the sorting equipment.

[0012] The nozzle blowing mechanism is provided with more than two manifold block blowing points, each manifold block is provided with more than one nozzle, and the nozzle is connected to the manifold block by a universal joint. An air storage tank is provided in the adjacent air path system.

[0013] The combined actuator of the waste textile sorting equipment and the pneumatic push plate mechanism are made of light metal or alloy materials, the push plate surface is provided with ventilation holes, and the bottom is provided with auxiliary wheels.

[0014] The combined actuator of the waste textile sorting equipment has a push plate body which is a rectangular panel with reinforced folded edges on both sides and the bottom.

[0015] Beneficial effects of the utility model:

[0016] 1. The combined actuator of the waste textile sorting equipment of the present invention is well suited for waste textile sorting, overcoming the shortcomings of the single blowing method and sorting method for textile picking. Since waste textiles are not packaged, are scattered, contain a lot of short fibers, and have large weight differences, when the actuator adopts an air blowing structure, heavy waste textiles cannot be blown away, and the bag-drop structure has problems such as loose sealing, material slipping, and uncertain falling time, which makes it easy to get stuck. The present invention adopts a complementary method of nozzle blowing and pneumatic push plate. For lighter and thinner textiles, the air blowing method can be used for picking, and for heavier textiles, the push plate can be used for detection, thereby ensuring the picking effect and improving the sorting efficiency.

[0017] 2. The combined actuator of the waste textile sorting equipment of the utility model adopts the complementary mode of nozzle blowing and pneumatic push plate. Quick exhaust valves are designed at both ends of the push plate actuator cylinder, and an air storage tank is designed in the air path adjacent to the nozzle, which ensures the execution power and speed, and the response is sensitive and fast, ensuring the classification and sorting effect and efficiency.

[0018] 3. The modular actuator of this waste textile sorting device features a push plate body with a breathable mesh and auxiliary wheels underneath, ensuring smooth operation. This reduces wind resistance to the push plate at high speeds, preventing the impact of wind force on the textile push. Made of lightweight metal or alloy, it is lightweight and labor-saving.

[0031] In order to make the technical concept and advantages of the invention more clearly understood, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the following embodiments are only used to explain and illustrate the preferred embodiments of the present invention and should not constitute a limitation on the scope of protection claimed in the patent application of the present invention.

[0032] Example 1

[0033] See also Figure 1-Figure 3 The utility model proposes a combined actuator suitable for waste textile sorting equipment, including a nozzle blowing mechanism and a pneumatic push plate mechanism, the power of the nozzle blowing mechanism and the pneumatic push plate mechanism adopts a pneumatic system;

[0034] The nozzle blowing mechanism includes a blowing control solenoid valve 10 and a nozzle 9, the air inlet of the blowing control solenoid valve 10 is connected to the air source, and the air outlet of the blowing control solenoid valve is connected to the nozzle; the pneumatic push plate mechanism includes a push plate 20, an execution cylinder 11 and an electromagnetic reversing valve 12, the air inlet of the electromagnetic reversing valve 12 is connected to the air source, the air outlet of the electromagnetic reversing valve is connected to the cylinder, and the front end of the cylinder push rod 11-1 is connected to the push plate 20.

[0035] In order to reduce the cylinder reversing resistance and increase the cylinder response speed, quick exhaust valves are respectively set in the gas circuits at the head and tail ends of the actuator cylinder.

[0036] When used in conjunction with waste textile sorting equipment, the nozzle 9 of the nozzle blowing mechanism and the cylinder 11 of the pneumatic push plate mechanism are fixed to the wall panel at the sorting grid opening of the conveyor curtain 21 of the sorting equipment (the other end is fixed to the cylinder support leg 23); the nozzle blowing control solenoid valve and the cylinder solenoid reversing valve are controllably connected to the control unit of the sorting equipment.

[0037] Example 2

[0038] See also Figure 4 、 Figure 5The combined actuator of the waste textile sorting equipment of this embodiment differs from that of Example 1 in that the pneumatic push plate mechanism comprises a push plate 20 made of a lightweight metal or alloy, with ventilation holes provided on its surface and auxiliary wheels 19 on its bottom. The push plate 20 is a rectangular panel with reinforced hems on both sides and the bottom.

[0039] Example 3

[0040] The combined actuator of the waste textile sorting equipment of this embodiment differs from that of Examples 1 or 2 in that, to increase the reliability of the cylinder and nozzle operation and compensate for temporary gas supply shortages, an air storage tank is provided in the adjacent air circuit system. To achieve a better blowing effect, the nozzle blowing mechanism is equipped with two or more manifold blocks 18, each of which is equipped with one or more nozzles 9, connected to the manifold blocks by universal joints.

[0041] The sorting equipment's control unit, comprised of an electrical control cabinet, an operating console, and an industrial computer, stores, analyzes, and controls the actions of each piece of waste textile by running a control program. This allows for hard object detection, component detection, and color detection of the waste textiles, as well as weight information and classification control. After each piece of waste textile undergoes hard object detection, component detection, color detection, and weighing, the industrial computer retrieves the relevant information and classifies it based on the information assigned to each piece of waste textile. The classified waste textiles 22 are then transported by a conveyor curtain 21 (which may have a main path and branch paths) and delivered to the corresponding sorting slots via an actuator. Once the classified waste textiles are conveyed to the corresponding slot by the conveyor curtain, the actuator delivers them to the corresponding slot conveyor curtain or sorting basket. If there are main and branch paths, unsorted waste textiles on the main path are delivered to the sorting basket at the end of the main conveyor curtain. Unsorted waste textiles on the branch conveyor curtains are delivered to the sorting basket at the end of the corresponding branch paths via a conveyor chain.

[0042] The combined actuator of the waste textile sorting equipment of the present invention adopts the complementary mode of nozzle blowing and pneumatic push plate. The air blowing mode can be used to pick out light and thin textiles, while the push plate pushing mode can be used to detect heavy textiles, thereby ensuring the classification and sorting effect, improving the sorting efficiency, being well applicable to the sorting of waste textiles, and overcoming the shortcomings of the single air blowing mode and sorting mode for the textile sorting function.

Those skilled in the art, guided by the existing technology, may make other modifications to the implementation of the present invention without inventive effort. Any modification made within the spirit and principles of the present invention or any simple replacement or equivalent substitution using conventional technical means in the art shall be included within the scope of protection of the present invention.
