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 of color sorters, spray valve installation is a critical step. Traditionally, spray valve installation utilizes a threaded connection, where the air connector is secured to an aluminum alloy housing or mounting plate via a threaded structure. While this installation method ensures a tight connection between the air connector and the spray valve, the specific nature of the threaded structure necessitates manual tightening of each air connector. This approach is not only time-consuming and labor-intensive, but can also lead to inconsistent tightening due to human error, impacting the performance stability and sorting accuracy of the entire color sorter.

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

[0004] First, it's difficult to completely avoid loose threads or uneven tightening during robot installation, which can reduce the seal between the air nozzle and the spray valve, increasing the risk of air leakage. Second, the complexity of threaded connections limits further improvements in production efficiency, especially in mass production environments, making it difficult to meet the requirements of fast, stable, and efficient assembly. The present invention provides a modular spray valve quick air connection device to address these technical issues. Summary of the Invention

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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 with reference to specific embodiments.

[0034] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a modular spray valve quick air connection device, including a plastic base plate 1, with preset nuts 2 provided at the four corners of the surface of the plastic base plate 1, a plurality of mounting grooves provided on one side surface of the plastic base plate 1, a plurality of preset fixing rings 3 provided on one side surface of the plastic base plate 1, and a plurality of ventilation interfaces 7 provided on the other side surface of the plastic base plate 1. 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 provided inside the mounting groove, a mounting ring 4 is connected to the interior of the preset fixing ring 3, and an air nozzle 5 is provided inside the mounting ring 4. The vent port 7, the mounting 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] The second fixing ring 9, first fixing ring 8, mounting ring 4, and air nozzle 5 are sequentially injection-molded and connected to the plastic base plate 1, achieving an integrated design in which the air connector components are directly integrated into the plastic base plate 1. This integrated air connector mounting plate structure eliminates the potential for air leakage caused by loose or leaky threads in traditional connection methods, significantly improving the smoothness and stability of airflow.

[0039] Crucially, the quick-connect air plate design simplifies the valve installation process, enabling direct installation without the traditional tightening process, thus ensuring consistent valve installation. This modular installation feature not only significantly improves the quality and efficiency of valve installation, but also reduces potential errors and variations during installation.

[0040] Furthermore, this integrated injection molding connection effectively prevents loosening between the air nozzle 5 and the air receiving plate. Even after prolonged use, the air nozzle 5 and the spray valve mounted thereon remain securely mounted, ensuring the air injection system remains in optimal working order and preventing problems such as unstable airflow and reduced jetting 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 efficient and stable working conditions during long-term use, and avoids equipment failures and maintenance issues that may be caused by loose components.

[0042] In this embodiment, a number of positioning teeth 6 are evenly distributed inside the mounting ring 4. These positioning teeth 6 penetrate the side wall of the gas connection nozzle 5 and firmly fix the gas connection nozzle 5 inside the preset fixing ring 3. Through this design, the positioning teeth 6 can effectively lock the gas connection nozzle 5, preventing it from loosening during long-term use, thereby ensuring the stability of the gas connection nozzle 5 and guaranteeing 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 installed with 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. 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, the actual jet performance of the spray valve may deviate from the initial design expectations due to the complexity of the color sorter's operating environment, especially after prolonged use. In this case, to ensure that the spray valve connected to the air nozzle 5 maintains good jet performance, technicians typically need to regularly disassemble the plastic base plate 1 and use specialized equipment to test the jet performance of multiple air nozzles 5 and spray valves. However, this testing method is not only time-consuming and labor-intensive, but also requires prolonged interruption of normal color sorter operation, resulting in a decrease in overall operating efficiency.

[0048] To address this technical challenge, this embodiment proposes a more efficient detection method. When air flow testing is required on the spray valve mounted on the air inlet 5, the servo motor 14 is activated. The servo motor 14 drives the rotating rod 12 via the rolling bearing 13, which in turn rotates the electric telescopic rod 11. Once the electric telescopic rod 11 has rotated to a preset position, it is opened, and the telescopic end drives the ventilation flow detection assembly 10 until the detection ring 101 is aligned with the spray valve to be tested.

[0049] It's worth noting that the rotation angle and telescopic distance of the electric telescopic rod 11 are pre-set based on the specifications of the plastic base plate 1 and the distribution of the gas inlet nozzles 5. When the detection ring 101 is precisely positioned directly above a particular valve, gas is injected into the valve and then passes through the valve into the sealing ring 105, the iron movable collar 103, the flow sensor 102, and the detection ring 101. At this point, the flow sensor 102 within the detection ring 101 measures the gas flow in real time and assesses whether it meets the standard.

[0050] If the test results indicate that the gas flow rate meets the requirements, the valve is considered to be functioning properly. Otherwise, there is a problem with the valve's gas flow and further inspection or replacement is required. To ensure test accuracy, when the test ring 101 is aligned with the valve, the outer side of the sealing ring 105 fits tightly against the valve opening. This distance is pre-set to ensure no leaks during the gas test, thus ensuring the accuracy of the test 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 several 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, to ensure accurate testing of the valve's jetting effect, technicians determined that it was essential to ensure a tight seal between the sealing ring 105 and the valve opening. To this end, the sealing ring 105 was designed to be offset a distance toward the air inlet 5, so that the bottom end of the sealing ring 105 and the valve opening were not in the same plane.

[0054] Based on this design, to ensure smooth operation during the inspection process, the electromagnet block 104 must first be activated before the electric telescopic rod 11 drives the inspection ring 101 to move to the spray valve. When powered, the electromagnet block 104 generates an attractive force, driving the iron movable ring 103 upward, allowing the inspection ring 101 to smoothly move directly above the spray valve.

[0055] Once the test ring 101 reaches the predetermined position, the electromagnet block 104 is de-energized, eliminating the suction force of the movable iron ring 103. Simultaneously, the return spring 106 pushes the movable iron ring 103 back into place, firmly pressing the sealing ring 105 against the valve opening. This design creates a reliable seal between the sealing ring 105 and the valve opening, ensuring no gas leaks during the test and thus ensuring the accuracy of the jet 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 scope of protection of the present invention.
