According to the TPU composite fabric composite processing equipment provided by the utility model, the mirror roller is used as a relatively coarse accurate measuring tool, the sizing control capacity of the mirror roller on the PUR glue is relatively limited, the sizing error is relatively large, the consumption of the PUR glue is easy to cause, and the cost is increased; anilox rolls, as a precision metering tool, have a precision metering capability for low viscosity fluids, but a relatively limited metering control capability for lower sizing for high viscosity fluids; according to the utility model, two metering tools are combined for use, after repeated transfer and metering of two mirror rollers, the sizing amount can be controlled within a certain range, and accurate metering of high-viscosity PUR glue under a lower sizing amount working condition is realized through gaps between the mirror rollers and the anilox rollers and grooves uniformly distributed on the anilox rollers.
In one possible implementation, the first mirror roller, the second mirror roller and the anilox roller are arranged in a semi-closed metal housing with an insulating layer.
In one possible implementation, the top of the inner wall of the metal shell is provided with a plurality of heating lamps. The heating lamp is arranged to heat the cloth cover to be more than 120 ℃, so that the PUR glue has better wettability and leveling property, and the peeling strength is improved.
In one possible implementation manner, the bottom inside the metal shell is provided with a glue recycling device, and a glue recycling port is arranged in the middle of the glue recycling device. The glue recycling device is used for recycling PUR glue dripped from the mirror roller in the glue transferring process.
In one possible implementation, the first mirror roller is attached to a scraper, and a V-shaped glue groove is formed between the scraper and the first mirror roller. The PUR glue is taken out from the glue groove by the first mirror roller rotating clockwise, and the first glue feeding amount control is completed under the action of the scraper. And under the stripping action formed by the second mirror roller with the speed difference and rotating anticlockwise and the gap between the two mirror rollers, the secondary transfer and the sizing amount control of the PUR glue are completed.
In one possible implementation, a composite press roll is provided behind the anilox roll. Under the action of the composite press roller, the full-coating effect of the PUR glue in the process of compositing the TPU film and the base cloth is realized, the higher peeling strength of the composite fabric is obtained under the condition of lower use amount of the PUR glue, the lighter and thinner composite fabric and softer hand feeling are realized, and the production cost is saved.
