Embodiment 1

[0030] Embodiment 1: a kind of composite membrane is prepared and assisted composite device with ptfe membrane, as figure 1 and 4 As shown, the composite device is used in the roll-to-roll coating equipment 1 for realizing large-scale coil coating. The roll-to-roll coating equipment 1 includes a frame 1-1, a base film delivery roller assembly 1-2, a ptfe film Conveying roller assembly 1-3, composite roller assembly 1-4 and plc system, base film conveying roller assembly 1-2, ptfe film conveying roller assembly 1-3 are all composed of multiple sets of roller shafts that can achieve a certain displacement adjustment, composite roller Components 1-4 are composed of a pair of hot pressing rollers that can realize relative displacement adjustment and also have heating function. Composite basement membrane.

[0031] Such as figure 1 and 2 As shown, the auxiliary composite device includes a group of fine-tuning adsorption mechanisms 2 symmetrically arranged on the frame 1-1, and ...

Embodiment 2

[0035] Embodiment 2: further, such as figure 1 , 2 , 4, the frame 1-1 of the compound device is provided with a rough adjustment adsorption mechanism with the same structure as the fine adjustment adsorption mechanism 2 but with different positions, that is, the coarse adjustment adsorption mechanism also includes being fixedly arranged on the frame 1-1 The drive assembly 2-1 is provided with a turntable 2-2 for rotation on the drive assembly 2-1, and the circular array on the turntable 2-2 is provided with 4-8 adsorption discs 2-3 that act on the ptfe membrane, and the adsorption disc 2 -3 are all parallel to the turntable 2-2. In this embodiment, there are specifically four adsorption disks 2-3. The adsorption disk 2-3 is a vacuum adsorption disk 2-3, and its adsorption holes are distributed in a uniform array along the surface of the adsorption disk 2-3. The strip hole 2-3-1, each adsorption plate 2-3 is connected with the total air box 2-4 through its own air duct (not sh...

Abstract

The invention discloses a ptfe film auxiliary compounding device for preparing a composite film, the compounding device is used in coating equipment, the compounding device comprises a group of fine adjustment adsorption mechanisms symmetrically arranged on a rack, and the fine adjustment adsorption mechanisms are arranged in a ptfe film conveying roller assembly area and close to a compounding roller assembly so as to realize adsorption type auxiliary conveying of a ptfe film into the compounding roller assembly; the fine adjustment adsorption mechanism comprises driving assemblies fixedly arranged on the rack, each driving assembly is rotationally provided with a rotating disc, each rotating disc is provided with a plurality of adsorption discs acting on the ptfe film in a circumferential array mode, the adsorption discs are connected with the main fan box through respective air ducts, and electromagnetic switch valves in signal connection with a plc system circuit are arranged in the air ducts; the driving assembly can drive the rotary disc to achieve lifting motion, telescopic motion and left-right swing along the horizontal plane. The device can effectively solve the problem that the ptfe film and the base film are difficult to compound, the overlap ratio of the ptfe film and the base film is improved, and the composite film is successfully prepared.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a ptfe membrane-assisted composite device for composite membrane preparation. Background technique [0002] Proton exchange membrane fuel cells have the advantages of low operating temperature, fast start-up, high specific power, simple structure, and convenient operation, and are recognized as the preferred energy source for electric vehicles and stationary power stations. Inside the fuel cell, the proton exchange membrane provides a channel for the migration and transport of protons, so that the protons pass through the membrane from the anode to the cathode, and form a circuit with the electron transfer of the external circuit to provide current to the outside world. Therefore, the performance of the proton exchange membrane has a great influence on the performance of the fuel cell Performance plays a very important role, and its quality directly affects the service life of the batte...
