TECHNICAL FIELD

[0001] The utility model relates to vacuum generating equipment technical field especially relates to a kind of integrated multistage vacuum generator. BACKGROUND

[0002] In modern industrial production, vacuum generators are widely used as a device to generate vacuum. However, traditional vacuum generators often have some limitations. For example, single-stage vacuum generators have limited suction capacity when facing large vacuum demands or complex working environments, making it difficult to meet the requirements of efficient production. Moreover, the structural design of traditional vacuum generators is not flexible enough, making it inconvenient to expand or adjust according to actual needs. In addition, in multi-station or applications requiring precise control of vacuum level, traditional vacuum generators lack effective integration and control means, resulting in complex equipment layout, increased cost, and difficulty in achieving precise vacuum level adjustment and monitoring.

[0003] Therefore, it is of great practical significance to develop an integrated multistage vacuum generator that can effectively solve the above problems. SUMMARY

[0005] To achieve the above technical solutions, the technical scheme of the utility model is as follows: an integrated multistage vacuum generator mainly consists of a combined application base, negative pressure generating components, a right support and a digital vacuum switch. The combined application base is internally provided with a centralized exhaust hole, providing a unified exhaust passage for the entire device. At least two negative pressure generating components are detachably installed on one side of the combined application base, with their exhaust ends communicating with the centralized exhaust hole, achieving multistage vacuum suction through cooperative work. The right support is sealingly connected to the air inlet end of the negative pressure generating components and communicates with the series connection interface of the negative pressure generating components, serving as support and auxiliary air path connection. The digital vacuum switch array is arranged above the right support, with one end sealingly connected to the negative pressure generating components, used for accurately controlling the on-off of high-pressure airflow and the on-off of back-blowing airflow, achieving accurate control and adjustment of the vacuum generation process.

[0006] Further, the combined application base is used as the basic structure of the entire integrated multi-stage vacuum generator, and the design of the centralized exhaust hole inside is the key. The centralized exhaust hole provides a common exhaust channel for each negative pressure generating component, enabling multiple negative pressure generating components to work together to improve overall exhaust efficiency. The diameter of the centralized exhaust hole is relatively large, which can effectively reduce the exhaust resistance and ensure that the negative pressure generating component can quickly exhaust gas when working, maintaining a stable vacuum degree. The material of the combined application base is selected from high-strength, corrosion-resistant metal or engineering plastic to ensure that it can withstand certain pressure and environmental impact during long-term use, ensuring the stability and reliability of the equipment.

[0007] Further, the structure and connection method: the negative pressure generating component includes a negative pressure body, the negative pressure body is provided with a through mounting hole, and the vacuum air suction port is in communication with the through mounting hole for sucking external gas. The negative pressure body is sealingly installed with a supersonic vacuum tube, and the gas outlet end of the supersonic vacuum tube is connected with a silencer. The supersonic vacuum tube is the core component for generating vacuum, which uses high-speed airflow to generate vacuum effect through a special structure. The design of the silencer effectively reduces the noise generated by the equipment during operation, reducing the disturbance to the working environment. The vacuum air suction port is arranged on the outer side of the negative pressure generating component, and at least two vacuum air suction ports are arranged in an array along the length direction of the negative pressure generating component. This design increases the range and efficiency of vacuum suction, and can simultaneously perform vacuum suction on multiple positions or a larger area.

[0008] Functional characteristics and innovative design: the diameter of the exhaust end of the negative pressure generating component is much smaller than that of the centralized exhaust hole. This design feature allows gas to be quickly exhausted from the negative pressure generating component and into the centralized exhaust hole during the exhaust process, forming an efficient exhaust flow and further enhancing the overall vacuum suction capacity. The negative pressure body is provided with a blowback hole in communication with the through mounting hole. When it is necessary to clean impurities in the vacuum air suction port or pipeline, high-pressure gas can be introduced through the blowback hole to realize reverse blowing cleaning, prolong the service life of the equipment and reduce maintenance costs. One end of the negative pressure body is provided with a series interface along the width direction, facilitating series connection between multiple negative pressure generating components, flexible expansion of the vacuum generation stages according to actual needs, and realization of different degrees of vacuum degree requirements.

[0009] Further, the right support is sealingly connected with the air inlet end of the negative pressure generating component, providing stable support for the negative pressure generating component, while ensuring the sealing of the air path. The right support is connected with the series interface on one side, ensuring that the high-pressure gas flow can smoothly enter each negative pressure generating component. The digital display vacuum switch array is arranged above the right support, which has precise vacuum degree detection and control function. Through the sealing connection with the negative pressure generating component, the digital display vacuum switch can monitor the vacuum degree in real time, and control the on-off of the high-pressure gas flow according to the preset parameters, so as to accurately adjust the vacuum degree. At the same time, the digital display vacuum switch can also control the on-off of the back blowing gas flow, realizing the automatic control of the back blowing cleaning function. The display screen of the digital display vacuum switch can directly display the current vacuum degree value, facilitating the monitoring and adjustment of the operator.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] 1) The integrated base is provided with a centralized exhaust hole, and at least two negative pressure generating components are detachably installed on one side of the integrated base and connected with the centralized exhaust hole. This integrated structure design enables multiple negative pressure generating components to work closely and share the centralized exhaust hole as an exhaust passage. Compared with the traditional single vacuum generator arranged in a scattered manner, the space is greatly saved, and the equipment structure is more compact. In the application scenarios of industrial automation production lines and other limited spaces, the layout and installation can be more convenient.

[0012] 2) The diameter of the exhaust end of the negative pressure generating component is much smaller than the diameter of the centralized exhaust hole. This design feature forms a structure similar to the Venturi effect. When the gas generated by the negative pressure generating component is exhausted, due to the diameter difference between the exhaust end and the centralized exhaust hole, the gas will flow faster when flowing through the exhaust end into the centralized exhaust hole. The rapidly flowing gas can be quickly exhausted from the equipment, reducing the exhaust resistance, thereby helping to maintain a low pressure environment inside the negative pressure generating component and enhancing the vacuum suction effect.

[0013] 3) The vacuum suction port is arranged on the outer side of the negative pressure generating component, and at least two vacuum suction ports are arranged in an array along the length direction. This layout enables the vacuum generator to perform vacuum suction from multiple directions, expanding the suction range and improving the adaptability to different shapes and sizes of workpieces.

[0014] 4) The supersonic vacuum tube is sealingly installed on the negative pressure body, and the supersonic vacuum tube generates a vacuum effect by using high-speed airflow through a special structure, which is the core component of the negative pressure generation. The negative pressure body is provided with a vacuum suction port communicated with the through installation hole, and the two work cooperatively. The external gas is sucked into the through installation hole through the vacuum suction port, and then a vacuum is generated under the action of the supersonic vacuum tube. This combination ensures an efficient vacuum generation process and can quickly generate high vacuum degree.

[0015] 5) The negative pressure body is provided with a series interface at one end in the width direction, facilitating the series connection between multiple negative pressure generating components. This design makes the integrated multi-stage vacuum generator have strong flexibility and expansibility. Users can easily increase or decrease the number of negative pressure generating components according to actual production needs, thereby adjusting the vacuum degree and air volume.

[0016] 6) The digital display vacuum switch array is arranged above the right support and is sealingly connected to one end of the negative pressure generating component, can monitor the vacuum degree in real time, and accurately control the on-off of the high-pressure airflow. Through the preset vacuum degree parameter, the digital display vacuum switch can automatically adjust the on-off of the high-pressure airflow according to the actual monitored vacuum degree, so that the vacuum degree is always maintained within the set range. This accurate control function is crucial for some industrial applications that require strict vacuum degree, such as the bonding process in the manufacturing process of electronic display screens. Accurate vacuum degree control can ensure that the layers of the display screen are tightly bonded without bubbles and defects, improving product quality. The display screen of the digital display vacuum switch can also intuitively display the current vacuum degree value, facilitating the real-time monitoring and adjustment of the operator, improving the operation convenience and controllability of the equipment.

[0017] 7) The right support is sealingly connected to the air inlet end of the negative pressure generating component and is in communication with the series interface, providing stable support for the negative pressure generating component. During the operation of the equipment, the negative pressure generating component will be subjected to certain reaction force when generating vacuum suction force.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0025] Please refer to the drawings Figs. 1 to 4 As shown in the drawings: an integrated multi-stage vacuum generator, including a combined application base 1 with a centralized exhaust hole, at least two negative pressure generating components 2 are detachably installed on one side of the combined application base 1; the exhaust end of the negative pressure generating component 2 is in communication with the centralized exhaust hole. The integrated structure design in this example enables multiple negative pressure generating components to work closely together and share the centralized exhaust hole as an exhaust passage. Compared with the traditional single vacuum generator arranged in a scattered manner, it greatly saves space and makes the equipment structure more compact. In the application scenarios with limited space such as industrial automation production lines, it can be more convenient to layout and install. For example, in electronic component mounting equipment, the compact integrated multi-stage vacuum generator can be more flexibly installed in the narrow working area, leaving more space for other components, improving the overall integration and work efficiency of the equipment. At the same time, multiple negative pressure generating components work together to provide greater vacuum suction capacity according to actual needs, meeting the requirements of different production tasks for vacuum degree and air volume.

[0026] On the basis of the above-mentioned embodiments, the diameter of the exhaust end of the negative pressure generating component 2 is much smaller than the diameter of the centralized exhaust hole. The diameter of the exhaust end of the negative pressure generating component is much smaller than the diameter of the centralized exhaust hole. This design feature forms a structure similar to the Venturi effect. When the gas generated by the negative pressure generating component is exhausted, due to the diameter difference between the exhaust end and the centralized exhaust hole, the gas will accelerate when flowing through the exhaust end into the centralized exhaust hole. The rapidly flowing gas can be quickly exhausted from the equipment, reducing the exhaust resistance, thereby helping to maintain a low air pressure environment inside the negative pressure generating component and enhancing the vacuum suction effect. For example, in the plastic film suction forming process, stable and powerful vacuum degree can ensure that the plastic film is tightly attached to the surface of the mold, and more accurate and higher quality products can be formed. Moreover, this structure helps to reduce the backflow and turbulence of gas during the exhaust process, further improving the stability of the vacuum degree, so that the vacuum generator can continuously provide a reliable vacuum environment during long-time continuous work.

[0027] On the basis of the above-mentioned embodiment, a vacuum suction port 21 is arranged outwardly on the side of the negative pressure generating component 2.

[0028] On the basis of the above-mentioned embodiment, at least two vacuum suction ports 21 are arranged along the length direction of the negative pressure generating component 2; and a metal quick pipe connector 22 is embedded on the vacuum suction port 21.

[0029] Such layout enables the vacuum generator to perform vacuum suction from multiple directions, expands the suction range, and improves the adaptability to workpieces of different shapes and sizes. For example, in the surface treatment process of irregularly shaped workpieces, such as the cleaning treatment before surface painting of automobile parts, the multi-directional vacuum suction ports can more comprehensively adsorb dust and impurities on the surface of the workpiece, ensuring the painting quality. The metal quick pipe connector embedded on the vacuum suction port facilitates quick connection and disassembly with various vacuum pipelines and equipment. When it is necessary to replace vacuum pipelines of different specifications or connect different vacuum equipment, the operator can easily perform plugging operation without the need for complex tools and long installation process, improving the use convenience and maintenance efficiency of the equipment and reducing the equipment downtime.

[0030] On the basis of the above-mentioned embodiment, the negative pressure generating component 2 comprises a negative pressure body 23 provided with a through mounting hole, and the vacuum suction port 21 is arranged in communication with the through mounting hole; an ultrasonic vacuum tube 24 is sealingly mounted on the negative pressure body 23; and a silencer 25 is connected to the gas outlet end of the ultrasonic vacuum tube 24. The ultrasonic vacuum tube is sealingly mounted on the negative pressure body, and the ultrasonic vacuum tube generates vacuum effect by high-speed airflow through a special structure, which is the core component of negative pressure generation. The negative pressure body is provided with a vacuum suction port in communication with the through mounting hole, and the two work cooperatively. External gas is sucked into the through mounting hole through the vacuum suction port, and then vacuum is generated under the action of the ultrasonic vacuum tube. Such combination ensures efficient vacuum generation process and can quickly generate high vacuum degree. For example, in the wafer handling link in the process of manufacturing semiconductor chips, high vacuum degree is required to accurately adsorb wafers, and the cooperation of the ultrasonic vacuum tube and the negative pressure body can meet this strict requirement, ensuring the stability and safety of wafers in the handling process, preventing wafers from being damaged, and improving the yield of chip manufacturing.

[0031] On the basis of the above embodiment, the muffler 25 is provided with an open type noise reduction channel; the muffler connected with the supersonic vacuum pipe outlet is provided with an open type noise reduction channel, which effectively reduces the noise generated by the equipment during operation. In the industrial production environment, especially in places sensitive to noise, such as laboratories, clean workshops, etc., low-noise vacuum generators can reduce the disturbance to the surrounding environment and operating personnel. For example, in a medical device manufacturing workshop, a quiet working environment helps to improve the work efficiency of workers and the quality of products, and also meets the relevant environmental protection and occupational health requirements. The presence of the muffler enables the integrated multi-stage vacuum generator to provide strong vacuum function without causing excessive noise pollution to the working environment.

In the actual working environment, the air often contains various impurities, if these impurities enter the interior of the vacuum generator, they may block the vacuum air outlet, supersonic vacuum pipe and other key components, affecting the normal operation of the equipment, reducing the vacuum degree and suction efficiency, and even causing damage to the equipment. For example, in the wood processing industry, there are many impurities such as wood chips, and the dirt filter can prevent wood chips from entering the vacuum generator, ensuring the long-term stable operation of the equipment, reducing the frequency of equipment maintenance and cleaning, prolonging the service life of the equipment, and reducing the use cost of the equipment.

[0033] On the basis of the above embodiment, the negative pressure body 23 is provided with a mounting hole extending outward; the negative pressure body 23 is provided with a back blowing hole communicated with the mounting hole; when it is necessary to clean the impurities in the vacuum air outlet or pipeline, high pressure gas can be introduced through the back blowing hole to realize reverse blowing cleaning. This design makes the cleaning and maintenance of the equipment more convenient and efficient. After a long time of use, even if a small amount of impurities enter the interior of the equipment through the dirt filter, they can be removed through regular back blowing cleaning operation. For example, in the food packaging industry, food particles or powders may enter the vacuum pipeline, and these impurities can be easily cleaned out by using the back blowing hole, ensuring the hygiene and normal operation of the equipment, and avoiding the influence of impurity accumulation on packaging quality and production efficiency; one end of the negative pressure body 23 is provided with a series connection interface along the width direction, and one end of the negative pressure body is provided with a series connection interface along the width direction, which facilitates the series connection between multiple negative pressure generating components. This design makes the integrated multi-stage vacuum generator have strong flexibility and expansibility, and users can easily increase or reduce the number of negative pressure generating components according to actual production needs, so as to adjust the vacuum degree and air suction amount.

[0034] On the basis of the above embodiment, the integrated multi-stage vacuum generator further comprises:

[0035] A right support 3; the right support 3 is sealedly connected with one end of the negative pressure generating component 2; the right support 3 is provided with a series interface on one side;

The above-mentioned digital display vacuum switch array is arranged above the right support and is sealedly connected with the negative pressure generating component at one end, which can monitor the vacuum degree in real time and accurately control the on-off of the high-pressure airflow. Through the preset vacuum degree parameter, the digital display vacuum switch can automatically adjust the on-off of the high-pressure airflow according to the actual monitored vacuum degree, so that the vacuum degree is always maintained within the set range. This accurate control function is crucial for some industrial applications that require strict vacuum degree, such as the bonding process in the manufacturing process of electronic display screens. Accurate vacuum degree control can ensure that the layers of the display screen are tightly bonded without air bubbles and defects, improving product quality. The display screen of the digital display vacuum switch can also directly display the current vacuum degree value, which is convenient for operators to monitor and adjust in real time, improving the operation convenience and controllability of the equipment; the right support is sealedly connected with the gas inlet end of the negative pressure generating component and is communicated with the series interface, providing stable support for the negative pressure generating component. During the operation of the equipment, the negative pressure generating component will be subjected to certain reaction force when generating vacuum suction force, and the right support can effectively withstand these forces to prevent the negative pressure generating component from shifting or shaking, ensuring the structural stability of the equipment. For example, on the high-speed automated production line, stable vacuum generator structure can ensure the accuracy and reliability of vacuum suction operation, avoid workpiece suction failure or falling due to equipment shaking, and ensure the smooth progress of the production process, improve production efficiency and product quality. At the same time, the sealed connection of the right support also ensures the integrity of the gas path, prevents gas leakage, and further improves the performance and safety of the equipment.

[0037] In the working process of the utility model, high-pressure airflow enters the negative pressure generating component through the right support. Inside the negative pressure generating component, when the high-pressure airflow passes through the supersonic vacuum tube, due to the special effect of supersonic airflow, vacuum suction force is generated at the vacuum suction port, and external gas is sucked into the through mounting hole through the vacuum suction port. Multiple negative pressure generating components work simultaneously and cooperatively to produce gas, which is discharged into the central exhaust hole of the combined application base through the exhaust end, and then discharged out of the equipment.
