Background
The composite cloth is obtained by deep processing of traditional non-woven fabrics, and the performance of the composite cloth is greatly improved compared with that of the traditional cloth, so that the composite cloth is not only made of materials and patterns, but also made a little more obvious than that of the traditional cloth in practicability. In the production and processing process of the composite cloth, under the influence of a processing machine, creases are formed on the surfaces of the base cloth and the fabric, and if the base cloth and the fabric are directly compounded together without leveling treatment, the phenomenon of hollowing of the composite cloth is caused, and the quality of the composite cloth is influenced. In addition, receive the influence of processing environment, base member cloth and surface fabric surface also have the dust deposit, if do not remove dust in time, when the veneer is connected, base member cloth and surface fabric joint strength are relatively poor, and when using for a long time, separation takes place easily for base member cloth and surface fabric, and then influences the quality of compound cloth. Moreover, when glue is smeared on the base cloth, the glue tank bearing the glue is directly exposed in the air, and the glue is easy to generate chemical reaction with the air, so that the composite effect of the base cloth and the fabric is influenced.
The invention patent No. 201711245277.0 discloses a dust removing device for composite cloth, which adopts a mode of repeatedly beating the cloth to knock off dust from the cloth, and although the mode can play a dust removing effect, the technical problem of how to keep the composite cloth in a stretched state needs to be solved before beating.
The invention patent with the patent number of 201711340821X discloses a special automatic dust removal cloth rolling machine for cloth processing, and the device can be used for wrinkle removal of composite cloth. In the patent, a plurality of steam drying holes are formed in the surface of the steam drying roller, and in the cloth processing process, hot steam penetrates through the steam drying holes to be in contact with cloth and is matched with ironing of an electric heating plate, so that the technical effect of eliminating wrinkles on the surface of the cloth is achieved. The patent has the following technical problems: cloth is horizontal transport, lets in the vapor in the steam drying roller after, vapor can pass through steam drying hole effusion steam drying roller to upward movement leads to vapor can not fully contact with cloth, and subsequent wrinkle removal effect can't be ensured. In addition, the device can only be used for processing one piece of cloth once, and if two pieces of cloth need to be processed simultaneously, a machine needs to be additionally arranged, so that cost saving is not facilitated.

In order to realize uniform gluing of the base cloth, a glue spreading roller 26 is rotatably connected at the glue outlet.
The dust removing roller 29 can cooperatively remove dust on the surface of the cloth and prevent the dust from dispersing in the dust removing cavity 28, and in design, the top of the dust removing cavity 28 is provided with four dust removing openings 281, two dust removing openings 281 are respectively positioned at two sides of one channel, and the other two dust removing openings 281 are respectively positioned at two sides of the other channel; the dust removal port 281 is communicated with the dust collection box 31 through the fan 30, and the dust collection box 31 is provided with a gas outlet, and a filter screen is clamped at the gas outlet.
Because the dust removal port is designed close to the channel formed by the dust removal roller 28, in the dust removal process, dust can be directly conveyed into the dust collection box 31 by the fan through a pipeline without dispersion and deposition in the dust removal cavity 28, and the dust removal effect on the cloth can be effectively ensured.
