[0030] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments. Embodiment

[0031] This embodiment provides a diaphragm cutting machine with a dust removal function. Refer to Figure 1 and Figure 2, including a frame 10, on which a cutting die 20 is provided. The cutting die 20 includes an upper die 21 and a lower die 22. The upper die 21 includes a substrate 211 and a cutting blade die 212. An installation groove is provided on the substrate 211, and a cutting blade die 212 is embedded and installed in the installation groove. An ion air outlet 213 and a negative pressure adsorption port 214 are provided on the substrate 211.

[0032] The negative pressure adsorption port 214 is set as a waist-shaped hole. A plurality of negative pressure adsorption ports 214 are distributed around the outer side of the cutting blade die 212. A negative pressure pipeline is provided in the substrate 211. One end of the negative pressure pipeline is connected to a vacuum dust collection device through a bellows pipe, and the other end is connected to a plurality of negative pressure adsorption ports 214. During operation, the negative pressure generated by the vacuum dust collection device adsorbs powder debris and other foreign matters below the substrate 211 through a plurality of negative pressure adsorption ports.

[0033] Preferably, for the diaphragm cutting machine with a dust removal function in this embodiment, in order to enhance the effect of the negative pressure adsorption port in adsorbing powder debris and other foreign matters, an ion fan device is provided. Positive and negative ions in the air are ionized through high voltage electricity to eliminate the static electricity on the powder debris and the diaphragm, so that the powder debris and other foreign matters can be separated from the product more quickly. Specifically, the ion air outlet 213 is set as a round hole type. A plurality of round hole type ion air outlets 213 are evenly distributed outside the negative pressure adsorption port, so that the ionized air blown out by the ion air outlet can contact the diaphragm surface more evenly. A plurality of ion air outlets 213 are connected to the air outlet of the ion fan device through an ion air duct and a pipeline in the substrate 211.

[0034] It should be noted that the cutting blade die 212 protrudes from the substrate 211, so that there is a gap between the substrate 211 and the lower die during die cutting and closing. Therefore, during die cutting and closing, the ion air outlet and the negative pressure adsorption port can perform dust removal operations normally.

[0035] At the same time, the parameters of the ion air outlet and the negative pressure adsorption port can also be adjusted as needed to adapt to different cutting conditions and diaphragm types.

[0036] Preferably, for the diaphragm cutting machine with a dust removal function in this embodiment, a lower knife plate seat 11 is further provided on the frame 10. A horizontally moving baffle 12 is provided on the lower knife plate seat 11. The baffle 12 is fixedly connected to the synchronous belt of the synchronous belt feeding mechanism. The synchronous belt feeding mechanism is arranged along the length direction of the lower knife plate seat 11. The baffle 12 is driven by the synchronous belt to push the diaphragm on the lower knife plate seat 11 towards the cutting die 20, realizing automatic feeding and cutting of the diaphragm.

[0037] Preferably, for the diaphragm cutting machine with a dust removal function in this embodiment, the lower die 22 is fixedly connected to the end of the lower knife plate seat 11. The upper die 21 is located above the lower die 22, and the upper die 21 is driven by a driving cylinder or a hydraulic cylinder to punch and cut the diaphragm on the lower die 22.

[0038] Preferably, for the diaphragm cutting machine with dust removal function in this embodiment, a diaphragm loading mechanism 30 is further provided at one end of the lower knife plate seat 11 away from the lower die 22. The diaphragm loading mechanism 30 includes a material bin 31. At the bottom of the inner cavity of the material bin 31, a liftable jacking mechanism 32 is provided. The jacking mechanism 32 is used to jack up the diaphragm in the inner cavity of the material bin 31. The jacking mechanism 32 includes a linear drive assembly (such as a jacking cylinder, a linear module or a synchronous belt drive mechanism, etc.) arranged along the Z-axis direction and a jacking plate. The linear drive assembly drives the jacking plate to lift the stacked diaphragm raw materials above, so that the uppermost diaphragm is always in the loading station.

[0039] Preferably, for the diaphragm cutting machine with dust removal function in this embodiment, the material bin 31 includes a bottom plate 311 and a material bin plate 312. On the bottom plate 311, chutes along the X-axis and Y-axis are provided. Four material bin plates 312 are arranged in pairs facing each other and are slidably connected to the bottom plate 311. One adjusting screw is screwed on each of the two pairs of oppositely arranged material bin plates 312. Two screw nuts with opposite screw directions are screwed on the adjusting screw. The two screw nuts with opposite screw directions are respectively fixedly connected to the two pairs of oppositely arranged material bin plates 312. By rotating the screw, the distance between the two pairs of oppositely arranged material bin plates 312 can be adjusted, so as to adjust the size of the inner cavity of the material bin and be suitable for the loading and cutting processing of diaphragms of various sizes.

[0040] Preferably, for the diaphragm cutting machine with dust removal function in this embodiment, a suction cup mechanism 32 is further provided above the material bin 31. The suction cup mechanism 32 is used to adsorb and transplant the uppermost diaphragm in the material bin 31 onto the lower knife plate seat 11. The suction cup mechanism 32 includes a pen-shaped cylinder fixedly arranged on the machine frame. The pen-shaped cylinder is arranged along the length direction of the lower knife plate seat 11 and is located above the material bin 31. At the action output end of the pen-shaped cylinder, a suction cup drive cylinder that expands and contracts along the Z-axis is connected. At the action output end of the suction cup drive cylinder, a suction cup mounting plate is connected. A plurality of waist-shaped holes are provided on the suction cup mounting plate. A plurality of vacuum suction cups are respectively installed in their respective waist-shaped holes in an adjustable position. During operation, first, the pen-shaped cylinder is in a contracted state, and the suction cup mounting plate is located directly above the material bin 31. The suction cup drive cylinder drives the suction cup mounting plate to move downward, so that the vacuum suction cups adsorb the diaphragm, and then move upward. The pen-shaped cylinder extends to push the suction cup mounting plate to move above the lower knife plate seat 11. The suction cup drive cylinder drives the diaphragm to move downward to discharge the material and then returns to the initial position.

[0041] Preferably, for the diaphragm cutting machine with dust removal function in this embodiment, a conveyor line is further provided at the discharge end of the lower die 22 for conveying the cut diaphragms and waste materials.

[0042] During actual operation, first place the diaphragm raw material to be cut into the material bin 31, and then adjust the distance between the material bin plates 312 by adjusting the screw 313 to adapt to the size of the diaphragm raw material. Next, start the lifting mechanism 32 and the suction cup mechanism 33, so that the lifting mechanism 32 lifts the diaphragm raw materials piece by piece upward, and the suction cup mechanism 33 adsorbs and transplants the topmost diaphragm raw material onto the lower knife plate seat 11. Then start the dial plate 12 to push the diaphragm towards the cutting die 20 for cutting. During the cutting process, the negative pressure suction port will adsorb the generated powder and foreign objects, and the ion air outlet will blow out the ionized air to remove static electricity, thereby keeping the surface of the diaphragm clean.
