Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of diaphragm cutting equipment, and in particular relates to a cutting device for processing alkaline water electrolysis diaphragms. Background Technology
[0002] Alkaline water electrolysis is one of the core pathways for green hydrogen production, and the diaphragm, as the "heart" of the alkaline electrolyzer, directly affects the electrolyzer's sealing performance, ion conduction efficiency, and long-term operational stability due to its dimensional accuracy and edge smoothness. Cutting diaphragms to specific shapes is difficult, easily resulting in burrs and unevenness. It's also challenging to cut multiple diaphragms of a specific shape at once, and waste collection and diaphragm debris collection during the cutting process are relatively troublesome. Utility Model Content
[0003] The purpose of this invention is to provide a cutting device for processing alkaline water electrolysis diaphragms. When cutting by connecting the annular top knife and the annular bottom knife, it can instantly cut multiple layers of diaphragms, solving the problems of low cutting efficiency, uneven cutting, and burrs in existing methods.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a cutting device for processing alkaline water electrolysis diaphragms, comprising a base plate, a diaphragm lead-out mechanism, a cutting mechanism, and a diaphragm waste winding mechanism. The base plate has a diaphragm lead-out mechanism at its input end, and a cutting mechanism at its center. The cutting mechanism includes a cutting plate, extrusion columns, and a cutting tube. The cutting plate comprises a square plate with raised bottom rings arranged in a matrix. Annular bottom blades are provided within the raised bottom rings. Each annular bottom blade has a discharge hole at its position. The cutting plate is embedded in the base plate. Four mounting columns are provided on the base plate at the location of the cutting plate. A fixed limiting sleeve is provided, and the extrusion column is movably inserted into the limiting sleeve. Two first cylinders are symmetrically arranged on both sides of the limiting sleeve to pull the extrusion column up and down. The extrusion column has tube holes in a matrix corresponding to the annular bottom knife. The cutting tube is movably inserted into the tube holes. A cutting cylinder is installed at the top of the extrusion column at each tube hole position. The telescopic shaft end of the cutting cylinder is fixed to the top of the cutting tube. An annular top knife is provided at the bottom end of the cutting tube. The base plate has a first fixed height roller and a second fixed height roller symmetrically arranged on both sides of the cutting mechanism. The output end of the base plate is provided with a diaphragm waste winding mechanism.
[0005] The present invention is further configured such that the diaphragm lead-out mechanism includes three sets of upper and lower diaphragm output cylinders and three sets of diaphragm guide rollers. Each set of upper and lower diaphragm output cylinders includes an upper diaphragm output cylinder and a lower diaphragm output cylinder. The diaphragm guide rollers include an upper diaphragm guide roller and a lower diaphragm guide roller. The upper diaphragm output cylinder and the lower diaphragm output cylinder are respectively arranged above and below the base plate. The top of the lower diaphragm output cylinder is higher than the upper surface of the base plate.
[0006] The present invention is further configured such that the tops of the first and second fixed-height rollers are higher than the upper surface of the base plate, and the tops of the first and second fixed-height rollers are higher than the top of the lower diaphragm output cylinder.
[0007] The present invention is further configured such that a compression ring is provided at the bottom of each tube hole position of the compression square column, the compression ring is the same size as the raised bottom ring, and an annular groove is provided between the raised bottom ring and the annular bottom knife.
[0008] The present invention is further configured such that the outer diameter of the cutting tube is 0.1-0.15 mm smaller than the inner diameter of the discharge hole, and the cutting tube is provided with an exhaust channel.
[0009] The present invention is further configured such that the diaphragm waste winding mechanism includes an inlet roller, a winding drum and a winding motor. The inlet roller is mounted on the base plate. The bottom of the inlet roller is lower than the top of the second fixed-height roller, but the bottom is higher than the upper surface of the base plate. The winding drum is rotatably mounted on the mounting frame and driven to rotate by the winding motor.
[0010] This utility model has the following beneficial effects: 1. This utility model can output and stack multiple rolls of diaphragm together and feed them into the cutting mechanism. Each cut can cut multiple positions at once. With multiple layers of overlapping diaphragms, many diaphragm products can be cut at once. After the diaphragm is cut, the waste material does not break. The waste material can be wound up using the diaphragm waste winding mechanism and the next set of cuts can be carried out. The cutting efficiency is high.
[0011] 2. The cutting process of this utility model is similar to that of scissors. When the annular top knife and the annular bottom knife at the bottom of the tube are connected for cutting, multiple layers of diaphragm can be cut instantly without burrs and the cut is smooth.
[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-7 This utility model relates to a cutting device for processing alkaline water electrolysis diaphragms, comprising a base plate 1, a diaphragm lead-out mechanism 2, a cutting mechanism 6, and a diaphragm waste winding mechanism. The base plate 1 has the diaphragm lead-out mechanism 2 at its input end, and the cutting mechanism 6 is located in the middle of the base plate 1. The cutting mechanism 6 includes a cutting plate 5, extrusion square columns 62, and a cutting tube 63. The cutting plate 5 includes a square plate 51 with raised bottom rings 52 arranged in a matrix on it. Annular bottom blades 53 are provided within the raised bottom rings 52. Each annular bottom blade 53 is located in the square plate 51 with a discharge hole 55. The cutting plate 5 is embedded in the base plate 1. Four mounting columns are provided on the base plate 1 at the location of the cutting plate 5, and limit sleeves are fixed on the mounting columns. The frame 61 has a pressing column 62 that is movably inserted into a limiting sleeve 61. Two first cylinders 611 are symmetrically arranged on both sides of the limiting sleeve 61 to pull the pressing column 62 up and down. The pressing column 62 has tube holes 623 arranged in a matrix corresponding to the annular bottom knife 53. The cutting tube 63 is movably inserted into the tube holes 623. A cutting cylinder 64 is installed at the top of the pressing column 62 at each tube hole 623 position. The telescopic shaft end of the cutting cylinder 64 is fixed to the top of the cutting tube 63. The bottom end of the cutting tube 63 is provided with an annular top knife 631. The base plate 1 has a first fixed height roller 3 and a second fixed height roller 4 symmetrically arranged on both sides of the cutting mechanism 6. The output end of the base plate 1 is provided with a diaphragm waste winding mechanism.
[0024] The diaphragm is output from the diaphragm lead-out mechanism 2, passes over the first fixed-height roller 3 and rests on the first fixed-height roller 3, then passes through the cutting mechanism 6, and rests on the second fixed-height roller 4, and is introduced into the diaphragm waste winding mechanism for winding.
[0025] The diaphragm must be wound up and pulled to move. During cutting, the operator presses down the extrusion column 62 to hold down the multiple layers of stacked diaphragms, then starts the operation to move multiple cutting cylinders 63 down simultaneously. When the cutting cylinders 63 align with the annular bottom knife 53, they quickly cut the diaphragm, like a pair of ring scissors. The cut is smooth and without burrs or unevenness. After cutting, the cutting cylinders 63 are pulled up first, then the extrusion column 62 is pulled up. Then, a section of waste diaphragm is wound up, and the extrusion column 62 is pressed down again. Then, the operation starts to move multiple cutting cylinders 63 down simultaneously. When the cutting cylinders 63 align with the annular bottom knife 53, they quickly cut the diaphragm. This process is repeated continuously. The cut diaphragm (circular) falls through the discharge hole 55. If it does not fall, the next diaphragm to be cut will be pushed down to move it.
[0026] The diaphragm output mechanism 2 includes three sets of upper and lower diaphragm output cylinders and three sets of diaphragm guide rollers. Each set of upper and lower diaphragm output cylinders includes an upper diaphragm output cylinder 21 and a lower diaphragm output cylinder 22. The diaphragm guide rollers include an upper diaphragm guide roller 23 and a lower diaphragm guide roller 24. The upper diaphragm output cylinder 21 and the lower diaphragm output cylinder 22 are respectively arranged above and below the base plate 1. The top of the lower diaphragm output cylinder 22 is higher than the upper surface of the base plate 1.
[0027] It can achieve the installation of three diaphragm raw material cylinders at the top and bottom, and then pass through the corresponding upper diaphragm guide roller 23 and lower diaphragm guide roller 24 (the upper diaphragm output cylinder 21 passes through the lower diaphragm guide roller 23 from below, and the lower diaphragm output cylinder 22 passes through the lower diaphragm guide roller 24 from above), thus realizing the multi-layer stacked output diaphragm.
[0028] The tops of the first fixed-height roller 3 and the second fixed-height roller 4 are higher than the upper surface of the base plate, and the tops of the first fixed-height roller 3 and the second fixed-height roller 4 are higher than the top of the lower diaphragm output cylinder 22.
[0029] The first fixed-height roller 3 and the second fixed-height roller 4 are designed to extend above the raised bottom ring 52 on the cutting plate 5. After cutting, the diaphragm will detach from the raised bottom ring 52 and will not get stuck or wrapped around it. This also facilitates easy winding.
[0030] The bottom of the extrusion column 62 is provided with an extrusion ring 622 at each position of the tube hole 623. The extrusion ring 622 is the same size as the raised bottom ring 52. An annular groove 54 is provided between the raised bottom ring 52 and the annular bottom knife 53.
[0031] The extrusion ring 622 and the raised bottom ring 52 are matched for extrusion. During cutting, the diaphragm will not be pulled or displaced, resulting in better cutting effect and reduced burr phenomenon.
[0032] The outer diameter of the cutting tube 63 is 0.1-0.15 mm smaller than the inner diameter of the discharge hole 55, and the cutting tube 63 is provided with an exhaust channel 632. When the cutting tube 63 is pulled up after cutting, the exhaust channel 632 exhausts the air and will not have a suction force on the cut diaphragm.
[0033] The diaphragm waste winding mechanism includes an inlet roller 7, a winding drum 8, and a winding motor 81. The inlet roller 7 is mounted on the base plate 1. The bottom of the inlet roller 7 is lower than the top of the second fixed-height roller 4, but the bottom is higher than the upper surface of the base plate 1. The winding drum 8 is rotatably mounted on the mounting frame and driven to rotate by the winding motor 81.
[0034] The roller 7 is introduced to limit the diaphragm and prevent it from moving upward.
