Description

Technical Field

[0001] The invention relates to the technical field of color sorter spray valve installation, in particular to a modular spray valve quick air connection device. Background Art

[0002] During the manufacturing and assembly process of the color sorter, the installation of the spray valve is one of the key links. Traditional spray valve installation usually adopts a threaded connection method, that is, the air joint parts are fixed to the aluminum alloy cavity or mounting plate through a threaded structure. Although this installation method can achieve a tight connection between the air joint and the spray valve, due to the particularity of the threaded structure, each air joint needs to be tightened manually one by one in actual operation. This method is not only time-consuming and labor-intensive, but also prone to inconsistent installation tightness due to human factors, which in turn affects the performance stability and sorting accuracy of the entire color sorter.

[0003] With the development of the color sorter industry, in order to improve production efficiency, some manufacturers have begun to try to use robots to replace manual labor to complete the threaded connection operation of spray valves. Although robots can speed up the installation to a certain extent, the inherent defects of threaded connections themselves are still difficult to overcome.

[0004] First, it is difficult to completely avoid loose threads or uneven tightening during robot installation, which will reduce the sealing between the air nozzle and the spray valve and increase the risk of air leakage. Secondly, the complexity of the threaded connection method limits the further improvement of production efficiency, especially in a mass production environment, it is difficult to meet the requirements of fast, stable and efficient assembly. In this regard, the present invention provides a modular spray valve quick air connection device to solve the above technical problems. Summary of the invention

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] like Figure 1-Figure 3 As shown, a modular spray valve quick air connection device provided by an embodiment of the present invention comprises a plastic base plate 1, four corners of the surface of the plastic base plate 1 are provided with preset nuts 2, one side surface of the plastic base plate 1 is provided with a plurality of mounting grooves, one side surface of the plastic base plate 1 is provided with a plurality of preset fixing rings 3, and the other side surface of the plastic base plate 1 is provided with a plurality of ventilation interfaces 7, and the plurality of preset fixing rings 3 are annular and closely distributed on the surface of the plastic base plate 1;

[0035] A first fixing ring 8 and a second fixing ring 9 are arranged inside the installation groove, a mounting ring 4 is connected inside the preset fixing ring 3, and an air nozzle 5 is arranged inside the mounting ring 4, and the ventilation interface 7, the installation groove, the first fixing ring 8, the second fixing ring 9, the preset fixing ring 3, the mounting ring 4 and the air nozzle 5 are all on the same axis;

[0036] The outer side of the first fixing ring 8 is connected to the inner wall of the mounting ring 4 .

[0037] In one embodiment of the present invention, the plastic base plate 1 is designed by injection molding of engineering plastics, and the preset fixing ring 3 is also integrally connected to the surface of the plastic base plate 1 by injection molding;

[0038] By means of injection molding, the second fixing ring 9, the first fixing ring 8, the mounting ring 4 and the air nozzle 5 are sequentially connected to the plastic base plate 1 by injection molding, thereby realizing an integrated design in which the air connector parts are directly integrated to the plastic base plate 1. This integrated air connector mounting plate structure eliminates the hidden danger of air leakage caused by loose threads or unsealed threads in the traditional connection method, and significantly improves the smoothness and stability of the airflow.

[0039] Most importantly, the design of the spray valve quick air connection plate simplifies the installation process of the spray valve, allowing it to be installed directly without the traditional screw connection process, thus ensuring the consistency of the spray valve installation. This modular installation feature not only greatly improves the installation quality and efficiency of the spray valve, but also reduces the errors and variations that may occur during the installation process.

[0040] In addition, the use of this integrated injection molding connection method effectively avoids the loosening phenomenon that may occur between the air nozzle 5 and the air receiving plate. Even if the air nozzle 5 and the spray valve installed thereon are used for a long time, they can still maintain a stable installation state, ensuring that the spray system is always in good working condition, avoiding problems such as unstable airflow and reduced spray accuracy caused by loose components.

[0041] This design fundamentally improves the reliability and service life of the entire system, further optimizes the performance of the spray valve, enables the equipment to maintain an efficient and stable working state during long-term use, and avoids equipment failures and maintenance problems that may be caused by loose components.

[0042] In this embodiment, a plurality of positioning teeth 6 are evenly arranged inside the mounting ring 4, and these positioning teeth 6 penetrate the side wall of the air nozzle 5 to firmly fix the air nozzle 5 inside the preset fixing ring 3. Through this design, the positioning teeth 6 can effectively lock the air nozzle 5 to prevent it from loosening during long-term use, thereby ensuring the stability of the air nozzle 5 and ensuring the reliable connection and efficient operation of the entire gas circuit system.

[0043] like Figure 4 and Figure 7 As shown, in one embodiment of the present invention, a through hole is opened at the center of one side surface of the plastic base plate 1, and a rolling bearing 13 is installed near the through hole on one side surface of the plastic base plate 1, and a servo motor 14 is installed on the other side surface of the plastic base plate 1;

[0044] The rolling bearing 13 is internally rotatably connected to a rotating rod 12, one end of which is mounted an electric telescopic rod 11, one end of which is provided with a ventilation flow detection component 10, the rotating rod 12 is arranged inside the through hole, and the output end of the servo motor 14 is fixedly connected to one end of the rotating rod 12.

[0045] One end of the electric telescopic rod 11 is connected to a detection ring 101, and one end of the detection ring 101 is connected to an iron movable ring 103, and one end of the iron movable ring 103 is provided with a sealing ring 105, and the sealing ring 105 is made of elastic plastic material;

[0046] A flow sensor 102 is installed inside the detection ring 101. The detection ring 101, the flow sensor 102, the iron movable ring 103 and the sealing ring 105 are all on the same axis.

[0047] After installing the spray valve in the air nozzle 5, due to the complexity of the working environment of the color sorter, the actual jet effect of the spray valve may deviate from the initial design expectations, especially after long-term use. In this case, in order to ensure that the spray valve connected to the air nozzle 5 can continue to maintain good jet performance, technicians usually need to regularly disassemble the plastic base plate 1 and use special equipment to test the jet performance of multiple air nozzles 5 and spray valves. However, this detection method is not only time-consuming and labor-intensive, but also requires a long interruption of the normal operation of the color sorter, resulting in a decrease in overall operating efficiency.

[0048] In view of this technical difficulty, a more efficient detection method is proposed in this embodiment. When it is necessary to perform a jet test on the spray valve installed on the air nozzle 5, the servo motor 14 can be started. The servo motor 14 drives the rotating rod 12 to rotate through the rolling bearing 13, so that the rotating rod 12 drives the electric telescopic rod 11 to rotate. When the electric telescopic rod 11 rotates to a preset position, the electric telescopic rod 11 is opened, and the telescopic end drives the ventilation flow detection component 10 to move until the detection ring 101 is on the same axis as a spray valve to be tested.

[0049] It is worth noting that the rotation angle and telescopic distance of the electric telescopic rod 11 are pre-set according to the specifications of the plastic base plate 1 and the distribution position of the air nozzle 5. When the detection ring 101 is accurately positioned directly above a spray valve, the gas will be injected into the spray valve and enter the sealing ring 105, the iron movable ring 103, the flow sensor 102 and the detection ring 101 through the spray valve. At this time, the flow sensor 102 in the detection ring 101 will detect the gas flow in real time and evaluate whether it meets the standard.

[0050] If the test result shows that the gas flow meets the requirements, the spray valve is judged to be working normally; otherwise, it means that the spray valve has a jetting problem and needs further inspection or replacement. At the same time, to ensure the detection accuracy, when the detection ring 101 is aligned with the spray valve, the outer side of the sealing ring 105 will fit tightly with the spray valve opening. This distance has been pre-set to ensure that there is no leakage during the gas detection process, thereby ensuring the accuracy of the detection results.

[0051] This automated detection method not only avoids the tedious disassembly process of traditional methods, but also reduces interference with the normal operation of the color sorter, greatly improving the detection efficiency and the overall operating efficiency of the equipment.

[0052] In this embodiment, an annular groove 107 is provided at one end of the iron movable ring 103, and the detection ring 101 is inserted into the inside of the annular groove 107, an electromagnet block 104 is installed on the outside of the detection ring 101, and a plurality of reset springs 106 are installed inside the annular groove 107, and one end of the reset spring 106 is connected to the end of the detection ring 101.

[0053] In this embodiment, in order to ensure the accuracy of the test of the jet effect of the spray valve, the technicians believe that the sealing performance between the sealing ring 105 and the spray valve opening must be guaranteed. To this end, the position of the sealing ring 105 is designed to be offset towards the air nozzle 5 by a distance, so that the bottom end of the sealing ring 105 and the spray valve opening are not on the same plane.

[0054] On this basis, in order to achieve smooth operation during the detection process, before the detection ring 101 is driven to move to the spray valve by the electric telescopic rod 11, the electromagnet block 104 needs to be activated first. After power is turned on, the electromagnet block 104 generates an adsorption force, driving the iron movable ring 103 to move upward, so that the detection ring 101 can be smoothly moved to the top of the spray valve.

[0055] Once the detection ring 101 reaches the predetermined position, the electromagnet block 104 is powered off, the adsorption force of the iron movable ring 103 disappears, and at the same time, the reset spring 106 pushes the iron movable ring 103 to reset, firmly pressing the sealing ring 105 against the spray valve opening. Through this design, a reliable seal is formed between the sealing ring 105 and the spray valve opening, ensuring that there is no gas leakage during the detection process, thereby ensuring the accuracy of the spray effect test.

[0056] This optimized design not only improves the accuracy and reliability of detection, but also simplifies the detection process, ensures effective sealing between the spray valve and the detection device, and helps to obtain more accurate test results.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
