Description

Technical Field

[0002] The battery membrane electrode is a key component of the hydrogen fuel cell system and is also vividly called the "heart" of the fuel cell. It is composed of a proton exchange membrane, a catalytic layer electrode and a gas diffusion layer. After being soaked in perfluorosulfonic acid diaphragm liquid, it undergoes a hot pressing process to form a three-in-one component. The membrane electrode, as a microchannel for multiphase material transfer and an electrochemical reaction site, directly determines the power density, durability and service life of the hydrogen fuel cell. Its preparation technology not only affects the battery performance, but is also crucial to reducing battery costs and improving battery specific power and specific energy. The membrane electrode promotes the electrochemical reaction of hydrogen and oxygen under the action of the catalyst to generate electricity and water, and the proton exchange membrane can conduct protons and block the passage of electrons and gases, ensuring the separation of hydrogen and oxygen during the electrolysis process. With the continuous advancement of technology, the preparation process and material selection of membrane electrodes are also constantly developing to improve their performance and reduce costs. The membrane electrode needs to be cut by a cutting device when in use.

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1-9As shown, a cutting device for hydrogen fuel cell membrane electrode production includes a bracket 1, a cutting mechanism 2 arranged on the bracket 1, a clamping and feeding mechanism 3 arranged on the bracket 1 and capable of horizontal sliding, and a feeding device 4 slidably mounted on the bracket 1. The cutting mechanism 2 includes a spline shaft 27 rotatably mounted on the bracket 1 at both ends, and a plurality of horizontally movable knife discs 26 are sleeved on the outer portion of the spline shaft 27; the cutting mechanism 2 also includes a slide rod 21 fixed in parallel to the bracket 1, a fixed knife holder 22 is fixed at the center of the two slide rods 21, one end of the fixed knife holder 22 is provided with a first limiting sleeve 23, and a plurality of movable knife holders 24 are slidably mounted on the slide rods 21 on both sides of the fixed knife holder 22, and one end of the movable knife holder 24 is provided with a second limiting sleeve 25, and a first stretching frame 29 is respectively provided on the fixed knife holder 22 and the movable knife holder 24, and a first adjusting device 210 is installed on the first stretching frame 29, and a first makeshift groove 211 for extending or contracting the first stretching frame 29 is provided at both ends of the first adjusting device 210, and a first bidirectional telescopic component 212 is provided on the top of the first adjusting device 210, and the output end of the first bidirectional telescopic component 212 is installed on the first stretching frame 29.

[0028] When the cutter disc 26 is adjusted, the telescopic action of the first bidirectional telescopic assembly 212 installed on the first adjusting device 210 drives the first extension frame 29 hinged thereto to expand or contract, so that the first extension frame 29 expands or contracts horizontally, so that the first extension frame 29 drives the movable tool holder 24 to move axially along the slide rod 21, so that the movable tool holder 24 drives the cutter disc 26 to move axially along the spline shaft 27 through the second limiting sleeve 25, and then adjusts the spacing of the cutter disc 26. During the cutting process, the spline shaft 27 is driven by the first rotary drive member 28 to rotate, so that the spline shaft 27 drives the cutter disc 26 set thereon to rotate at high speed, and then the cutter disc 26 cuts the material.

[0029] See also Figure 3 and Figure 7When the tool 32 is in the unlocking state, the tool 32 can be unlocked by the tool 322, and the tool 320 can be unlocked when the tool 32 is unlocked.

[0030] When the spacing of the upper clamping structure 32 needs to be adjusted, the second rotating drive member 315 drives the bidirectional threaded rod 314 to rotate, so that the bidirectional threaded rod 314 drives the sliding mounting sleeve 313 to slide along the first sliding groove 312. At the same time, the sliding mounting sleeve 313 drives the second extending frame 321 set at the bottom to expand or contract horizontally, thereby driving the upper pressing block 322 at the bottom of the second extending frame 321 to move horizontally, thereby adjusting the spacing between the upper pressing blocks 322, so that after the upper pressing blocks 322 are adjusted, the cutter disc 26 is between the upper pressing blocks 322 to avoid affecting the cutting of the material by the cutter disc 26.

[0031] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, the clamping and feeding mechanism 3 also includes a lower clamping mechanism 33 which is arranged in the first slide 31 and can be raised and lowered. When the lower clamping mechanism 33 rises, it can cooperate with the upper clamping structure 32 to fix the material. The lower clamping mechanism 33 includes two side panels 331, and a base 332 is arranged between the two side panels 331. The inner side of the two side panels 331 is longitudinally installed with a fourth telescopic component 335 for driving the base 332 to rise and fall.

[0032] When the material is transported to the inside of the first slide 31, the fourth telescopic assembly 335 fixed on the inside of the side plate 331 drives the base 332 to move longitudinally, so that the base 332 drives the top block 333 set on the top to move upward, so that the top block 333 cooperates with the upper pressure block 322 to clamp the material.

[0033] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 9When the cam 331 is unlocked, the lock 332 is unlocked and the lock 333 is unlocked.

[0034] When the spacing between the top blocks 333 is adjusted, the second bidirectional telescopic component 354 drives the third extension frame 351 to expand or contract in the horizontal direction, so that the third extension frame 351 drives the top blocks 333 to move horizontally through the fixed shaft 334, thereby adjusting the spacing between the top blocks 333. While the top blocks 333 adjust the spacing, the top blocks 333 slide along the second sliding groove 3322 through the slider 3331 set at the bottom, so that the top blocks 333 are adjusted to the same horizontal axis.

[0035] See also Figure 1 and Figure 3 As shown, the clamping and feeding mechanism 3 also includes a first telescopic component 34 for driving the first slide 31 to slide. The first telescopic component 34 is installed on the bracket 1, and the output end of the first telescopic component 34 is transmission-connected to the first slide 31.

[0036] When the first slide 31 needs to move, the first telescopic assembly 34 fixed on the bracket 1 is extended and retracted, so that the first telescopic assembly 34 drives the first slide 31, and then the first slide 31 moves horizontally along the slide rail at the bottom of the bracket 1 through the bottom slide groove.

[0037] See also Figure 1 and Figure 5 As shown, the feeding device 4 includes two groups of second slides 41 slidably mounted on the bracket 1, a fixed plate 43 is provided on the second slide 41, and a third telescopic component 44 is also provided on the second slide 41. The output end of the third telescopic component 44 is connected to the clamping plate 45. When the third telescopic component 44 drives the clamping plate 45 upward, the contact between the clamping plate 45 and the fixed plate 43 clamps the material.

[0038] When the material needs to be transported into the clamping and feeding mechanism 3, the material is placed on the upper end surface of the clamping plate 45, and then the clamping plate 45 is driven to move longitudinally by the third telescopic component 44, so that the clamping plate 45 and the fixed plate 43 are closed, thereby clamping the edge of the material.

[0039] See also Figure 1 and Figure 5 As shown, a second telescopic assembly 42 for driving the second slide 41 to move horizontally is further provided on the outer side of the bracket 1 , and an output end of the second telescopic assembly 42 is transmission-connected to the second slide 41 .

[0040] When it is necessary to add material, the second telescopic component 42 fixed on the bracket 1 drives the second slide 41, so that the second slide 41 moves to the inside of the clamping and feeding mechanism 3, so that the fixed plate 43 and the clamping plate 45 transport the clamped material to the inside of the clamping and feeding mechanism 3.

[0041] When the present application works, the material is placed on the upper end surface of the clamping plate 45, and then the clamping plate 45 is driven to move longitudinally by the third telescopic component 44, so that the clamping plate 45 and the fixed plate 43 are closed, thereby clamping the edge of the material, and then the second telescopic component 42 fixed on the bracket 1 drives the second slide 41, so that the second slide 41 moves to the inside of the clamping and feeding mechanism 3, so that the fixed plate 43 and the clamping plate 45 convey the clamped material to the inside of the clamping and feeding mechanism 3, and then the third stretching frame 351 is driven to expand and contract horizontally by the second two-way telescopic component 354, so that the third stretching frame 351 drives the top block 333 to move horizontally through the fixed shaft 334, thereby adjusting the distance between the top blocks 333, and then the fourth telescopic component 335 fixed on the inner side of the side plate 331 drives the base 332 to move longitudinally, so that the base 332 drives the top setting top block 333 upward, The top block 333 cooperates with the upper pressure block 322 to clamp the material, and then the first telescopic component 34 fixed on the bracket 1 is extended and retracted, so that the first telescopic component 34 drives the first slide 31 to move horizontally, so as to transport the material clamped by the top block 333 and the upper pressure block 322 to the processing area, and the first bidirectional telescopic component 212 installed on the first adjusting device 210 is extended and retracted to drive the first stretching frame 29 hingedly arranged therewith, so that the first stretching frame 29 expands or contracts horizontally, so that the first stretching frame 29 drives the movable tool holder 24 to move axially along the slide rod 21, so that the movable tool holder 24 drives the cutter disc 26 to move axially along the spline shaft 27 through the second limiting sleeve 25, and then adjusts the spacing of the cutter disc 26, and then drives the spline shaft 27 to rotate through the first rotary drive member 28, so that the spline shaft 27 drives the cutter disc 26 arranged thereon to rotate at high speed, so that the cutter disc 26 cuts the material.
