Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and more particularly to an automatic filter membrane intercepting device with visual positioning and continuous adjustability. Background Art

[0002] Atmospheric aerosols are the general term for solid and liquid particulate matters suspended in the atmosphere, mainly including carbon-containing components, sulfates, nitrates, ammonium salts, metals and non-metallic elements, etc. They have serious impacts on human health, environmental quality, atmospheric visibility and climate change, and are the main influencing factors for air pollution events. Therefore, quantitative analysis of the chemical composition of atmospheric fine particulate matter is of great significance for studying the contributions of different pollution sources. The existing monitoring methods mainly collect aerosols in the atmosphere onto a filter membrane through an air pump, and then intercept a certain area of the filter membrane for analysis on a machine after various pretreatment processes. Therefore, accurate interception of the filter membrane is an important prerequisite for accurate analysis data. Currently, when intercepting the filter membrane, it is mostly manually cut with scissors. This method cannot ensure accurate quantitative cutting of the filter membrane, and the efficiency is very low, affecting the timeliness of experimental analysis and resulting in a large labor cost.

[0003] Therefore, it is necessary to design a multifunctional adjustable automatic filter membrane intercepting device that can automatically cut quantitatively. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automatic filter membrane intercepting device with visual positioning and continuous adjustability, which can realize functions such as automatic positioning, quantitative cutting, and self-cleaning, and is convenient and reliable to use.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: An automatic filter membrane intercepting device with visual positioning and continuous adjustability, including a frame, a turntable is arranged on the frame, a plurality of support seats are evenly distributed around the turntable, a blade self-cleaning device is arranged on the frame on the right side of the turntable, a hydraulic cylinder is fixedly connected to the top of the frame, a storage block is fixedly connected to the top of each support seat, a storage groove is opened at the top of the storage block, a side groove communicating with the storage groove is opened at the top of the storage block, a connecting block is connected to the hydraulic cylinder, and an adjustable ring knife quantitative cutting device is fixed to the bottom of the connecting block. A visual positioning device is also arranged on the frame.

[0006] Preferably, the blade self-cleaning device adopts a vacuum adsorption cleaning device, including an adsorption device and a vacuum pump. The adsorption device is connected to the vacuum pump, and the self-cleaning function of the blade can be realized.

[0007] Preferably, the visual positioning device is connected to the controller through a control line. The hydraulic cylinder is slidably arranged on a transverse slide rail that can be longitudinally fine-tuned. The hydraulic cylinder is connected to the controller through a sliding drive device. By identifying the actual sampling area of the filter membrane, the position of the core cutter cutting can be accurately located.

[0008] Preferably, the core cutter quantitative cutting device includes a servo motor, an upper cover, a fork, a core cutter, a hydraulic push rod, a fixed tool holder, a rotating tool holder, a rotating shaft, a ring groove and an adjustment knob. The top of the servo motor is fixed on a connecting block, and the servo motor is also arranged on the upper cover. A fork is arranged on the side of the upper cover. The upper end of the fork is connected to the output end of the servo motor, and the lower end of the fork is fixed to the adjustment knob. The adjustment knob is slidably matched with the ring groove. The ring groove is arranged on the side wall of the core cutter. The core cutter is correspondingly arranged below the upper cover. One side of the fixed tool holder is fixed on the inner wall of the core cutter, and the other side of the fixed tool holder is matched with one side of the rotating tool holder through a rotating shaft. The other side of the rotating tool holder is arranged in contact with the inner wall of the core cutter, and the rotating tool holder is also connected to the adjustment knob. The servo motor controls the rotation action of the fork through the controller, and then adjusts the included angle between the rotating tool holder and the fixed tool holder. Together with the core cutter, it can directly perform quantitative cutting. After cutting, the sample is pushed out through the hydraulic push rod, so that the sample falls into the storage groove. A scale is arranged on one side of the ring groove to facilitate adjusting the cutting area.

[0009] Preferably, an infrared lamp induction device is arranged at the central hole of the support seat, and the infrared lamp induction device is connected to the controller. When a filter membrane is placed, the infrared lamp induction device is blocked, and at this time the punching device is in a working state. When the infrared induction device senses that there is no filter membrane placed in the storage groove, the punching device automatically stops working.

[0010] The beneficial effects of the present invention: The structure of the present invention is reasonably designed. The position of the core cutter quantitative cutting device is controlled by the visual positioning device and the controller, so that it can cut off the white edge of the filter membrane and quantitatively cut the required amount of the filter membrane at the same time. The accurate automatic cutting size is realized through the servo motor, and multiple workstations are provided for placing the filter membrane, so that continuous and quantitative cutting of multiple filter membranes can be realized. And after each cutting is completed, parts such as the core cutter, the fixed tool holder and the rotating tool holder are self-cleaned. The whole process has a high degree of automation, accurate quantification, and is convenient, reliable and easy to use. Description of the Drawings

[0020] It should be noted that the blade self-cleaning device 6 adopts a vacuum adsorption cleaning device, including an adsorption device 61 and a vacuum pump 62, and the adsorption device 61 is connected to the vacuum pump 62.

[0021] It should be noted that the visual positioning device 20 is connected to the controller 16 through a control line, the hydraulic cylinder 7 is slidably arranged on a horizontally adjustable longitudinal slide rail 21, and the hydraulic cylinder 7 is connected to the controller 16 through a sliding driving device.

The top of the steering gear 10 is fixed on the connecting block 8, and the steering gear 10 is also arranged on the upper cover 11. A fork 12 is arranged on the side of the upper cover 11. The upper end of the fork 12 is connected to the output end of the steering gear, and the lower end of the fork 12 is fixed to the adjusting knob 26. The adjusting knob 26 is slidably matched with the ring groove 25. The ring groove 25 is arranged on the side wall of the ring knife 13. The ring knife 13 is correspondingly arranged below the upper cover 11. One side of the fixed tool holder 22 is fixed on the inner wall of the ring knife 13, and the other side of the fixed tool holder 22 is matched with one side of the rotating tool holder 23 through the rotating shaft 24. The other side of the rotating tool holder 23 is arranged in contact with the inner wall of the ring knife 13, and the rotating tool holder 23 is also connected to the adjusting knob 26. The steering gear controls the rotation action of the fork through the controller, thereby adjusting the included angle between the rotating tool holder and the fixed tool holder 22.

After all the filter membranes are cut, the cut filter membranes are uniformly taken out from the side groove 5, and the storage groove is cleaned by manual cleaning to facilitate the next cutting. The whole process is fully automated, easy to use and highly efficient.
