Description

Technical Field

[0001] The utility model belongs to the technical field of fabric processing and relates to a fabric surface film laminating device. Background Art

[0002] The film laminating process is a common processing method. It can cover a film material on the surface of the fabric, thereby enhancing the waterproof, stain-proof, mildew-proof and other properties of the fabric. Due to the certain elasticity of the fabric, the conventional film laminating cannot penetrate into the gaps after the fabric is stretched, resulting in a general finished product effect. Therefore, it is very necessary to design a fabric surface film laminating device. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a fabric surface film laminating device.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A fabric surface film laminating device includes a frame. It is characterized in that a material guiding roller group is installed at the feeding end of the frame. A first stretching roller is arranged behind the material guiding roller group. Both ends of the first stretching roller are connected with an adjusting mechanism. A second stretching roller is arranged below the first stretching roller. A film material spraying device is arranged between the first stretching roller and the second stretching roller. The film material spraying device is installed on the frame and is parallel to the fabric conveying direction. An oven is arranged behind the second stretching roller. A heating element and an exhaust device are installed in the oven. A discharging roller group is arranged behind the oven.

[0005] The working principle of the utility model is as follows: The fabric is preliminarily flattened by the material guiding roller group and then conveyed to the first stretching roller. The fabric is stretched and extended by the first stretching roller. Then, the surface of the fabric is coated by the film material spraying device. After the coating is completed, it is retracted by the second stretching roller. After retraction, it is sent into the oven. Under the action of the heating element and the exhaust device, the fabric is dried. Then, it is flattened by the discharging roller group and exported.

[0006] The adjusting mechanism includes a mounting frame. A guide groove is arranged on the mounting frame. A linear motor is installed in the guide groove. The linear motor is connected to the end of the first stretching roller.

[0007] With the above structure, the overall tension of the fabric is adjusted by driving the first stretching roller to move up and down by the linear motor, assisting the unfolding of the fabric.

[0008] Both the material guiding roller group and the discharging roller group are composed of hot pressing rollers.

[0009] With the above structure, while playing a role in flattening, it can preheat and dry the fabric, which is beneficial to subsequent film material coating.

[0010] The first stretching roller is integrally a convex roller.

[0011] Adopting the above structure is conducive to the stretching of the fabric.

[0012] The second stretching roller is integrally a concave roller.

[0013] Adopting the above structure is conducive to the retraction of the fabric.

[0014] Compared with the prior art, the fabric surface film laminating device has the following advantages: by arranging the first stretching roller and the second stretching roller and cooperating with the adjusting mechanism, the present utility model can perform adaptive coating according to the elasticity of the fabric, ensure that film lamination can also be carried out in the gap after stretching, and ensure the overall film lamination effect.
