Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a pre-processing device for a fabric folding machine. Background Art

[0002] Non-woven fabrics are made of chemical fibers and plant fibers on a wet or dry papermaking machine with water or air as the suspension medium. Although they are cloths, they are not woven, so they are called non-woven fabrics. Non-woven fabrics are a new generation of environmentally friendly materials with advantages such as good strength, breathability and waterproofness, environmental protection, flexibility, non-toxicity and tastelessness, and low price. In daily life, non-woven fabrics of various sizes are needed, so the non-woven fabrics need to be folded. When folding the fabrics, the rolled non-woven fabrics need to be stretched and flattened first.

[0003] For example, in the patent application with publication number CN 108589149 B in the prior art, a feed piece, a discharge piece, a guide roller, and a stretching piece are arranged between the left plate and the right plate. The feed piece and the discharge piece are arranged in parallel up and down. The feed piece includes a first feed pressure roller and a second feed pressure roller. The first feed pressure roller is arranged directly above the second feed pressure roller. The discharge piece includes a first discharge pressure roller and a second discharge pressure roller. The first discharge pressure roller is arranged directly above the second discharge pressure roller. A stretching piece and a guide roller are arranged in sequence behind the feed piece and the discharge piece. The stretching piece includes a left rod, a right rod, a stretching motor, and a stretching roller. The beneficial effects of the present invention are: the feed piece and the discharge piece flatten the non-woven fabric to facilitate the folding process. The non-woven fabric can be stretched twice by the arranged stretching piece to ensure that the non-woven fabric is fully stretched without wrinkles.

[0004] However, when the device is in use, the distance between the two upper and lower conveying rollers cannot be adjusted, so that when in use, fabrics of different thicknesses cannot be flattened and stretched, thereby reducing the adaptability of the device.

[0005] Therefore, it is necessary to provide a pre-processing device for a cloth folding machine to solve the above technical problems. Utility Model Content
