[0025] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0026] This application provides a vacuuming device with a blowing function. The vacuuming device is used in the production of grid boards and is offset on one side of the shaping device used to shape the grid boards in the grid board production line. The vacuuming device integrates vacuuming and blowing functions and can perform vacuuming and blowing on the shaping device.

[0027] like Figure 1 , 2 As shown, the vacuum device 100 includes a frame 10 and a vacuum system 20 and a blowing system 30 mounted on the frame 10.

[0028] like Figure 1-4As shown, the vacuum system 20 includes multiple vacuum components 1 mounted side-by-side on the frame 10 in a left-right direction. Each vacuum component 1 includes a vacuum pipe 11, a gas storage tank 12, a connecting pipe 13, and a vortex pump 14 connected in sequence. The gas storage tank 12 has an inlet 121 and an outlet 122, with the inlet 121 located below the outlet 122. The vacuum pipe 11 connects the shaping device and the inlet 121, and the connecting pipe 13 connects the outlet 122 and the vortex pump 14. The vacuum pipe 11, the gas storage tank 12, and the connecting pipe 13 are connected in sequence to form a vacuum pipeline between the shaping device and the vortex pump 14. The vortex pump 14 operates to apply a suction negative pressure within the vacuum pipeline, thereby stably and efficiently vacuuming the shaping device.

[0029] In this embodiment, the vacuum system 20 includes three vacuum components 1, which are simultaneously connected to the shaping device to achieve high-flow-rate, highly stable synchronous suction operation.

[0030] In this embodiment of the application, the capacity of the gas storage tank 12 is preferably 0.4m³ to 0.8m³. Its air inlet 121 is opened near the bottom of the gas storage tank 12, and its air outlet 122 is opened near the top of the gas storage tank 12. This design helps gas-solid separation, ensures that the air entering the vortex air pump 14 is clean and stable, and effectively extends the service life of the vortex air pump.

[0031] The vortex air pump 14 is a vortex air pump with a power of 5.5kW, a flow rate of 360m³ / h, and a pressure of 40kPa. Its air inlet is sealed to the air outlet 122 of the air storage tank 12, and its exhaust outlet is open to the external environment. When working, it can provide a stable and effective vacuum pressure to the shaping device.

[0032] To achieve precise control of the vacuum level in the sizing device, each vortex pump 14 is equipped with an independent frequency converter (not shown in the figure). The frequency converter is electrically connected to the corresponding vortex pump and can adjust the speed of the vortex pump according to preset parameters. A vacuum pressure gauge (not shown in the figure) is installed at each vacuum pipe 11. The vacuum pressure gauge is connected to the corresponding frequency converter and is used to monitor the negative pressure value in the corresponding pipe in real time, feeding the pressure signal back to the corresponding frequency converter to form a closed-loop control system. When the vacuum pressure gauge detects that the pressure in the pipe exceeds the set range, the frequency converter automatically adjusts the speed of the corresponding vortex pump to ensure that the vacuuming operation of each vacuuming component 1 on the sizing device is continuous, stable, and efficient.

[0033] like Figure 1 , 5As shown in Figure 6, the blowing system 30 includes a fan 2 and an exhaust duct 3 mounted on the frame 10. The fan 2 and multiple vacuum components 1 are arranged side by side in the left-right direction. One end of the exhaust duct 3 is connected to the exhaust port of the fan 2, and the other end faces the forming device. When the fan 2 operates, it provides a strong and uniform cooling airflow to the grid plate on the forming device through the exhaust duct 3 to improve the forming efficiency of the grid plate. In this embodiment, the fan 2 is a fan with a power of 4kW, an airflow of 1174m³ / h to 2062m³ / h, and a pressure of 4603Pa to 4447Pa.

[0034] Each vacuum pipe 11 and exhaust pipe 3 is equipped with a stainless steel ball valve 4, which controls the flow rate of the corresponding pipe and is used for segmented isolation and flow regulation of multiple vacuum components 1.

[0035] like Figure 1-3 As shown, the frame 10 includes a base frame 5 and a first fixed frame 6 and a second fixed frame 7 mounted side by side on top of the base frame 5 in the left-right direction. Three air tanks 12 are fixedly mounted on the base frame 5, three vortex air pumps 14 are fixedly mounted on the first fixed frame 6, and the blower 2 is fixedly mounted on the second fixed frame 7. Each air tank 12 is located directly below the corresponding vortex air pump 14, which effectively reduces the length of the connecting pipe 13, thereby reducing pressure loss.

[0036] Several casters 8 are installed under the base frame 5. The casters 8 are arranged in pairs on the bottom of the base frame 5 to ensure the stability of the frame 10. The casters 8 are all casters, which facilitate the movement of the entire vacuuming device 100. Furthermore, the casters are equipped with brakes to facilitate the positioning of the entire vacuuming device 100.

[0037] like Figure 1 , 6 As shown, at least one pair of connecting rods 9 are fixedly installed on the side of the base frame 5 facing the shaping device. Each connecting rod 9 is fixedly connected between the base frame 5 and the shaping device, so that the shaping device and the vacuuming device 100 are connected relative to each other, and the two can move synchronously.

[0038] The vacuuming device of this application has a simple structure and is easy to adjust. It integrates blowing and vacuuming functions. The vacuuming system performs stable and efficient vacuuming operations on the shaping device to improve the forming efficiency and quality of the grid plate. The blowing system provides a strong and uniform cooling airflow to the grid plate at the shaping device to improve the forming efficiency of the grid plate.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
