Description

Technical Field

[0001] The utility model belongs to the field of film production, and in particular relates to a surface roughness detection device for a skin-friendly thermoplastic polyurethane film. Background Art

[0002] Skin-friendly thermoplastic polyurethane film is a plastic film with excellent performance and good touch. It has high air permeability and helps to keep the skin surface dry. It is suitable for making close-fitting clothing, shoes and other products. The microporous structure on the surface can prevent moisture from penetrating, while helping to discharge body sweat and maintain a comfortable and dry environment. It has good flexibility and lightness, making the wearer feel comfortable when moving and almost unable to feel the existence of the film. It has good environmental performance and can be recycled and reused, with little impact on the environment. It is widely used in clothing, shoes, medical equipment, sports equipment, home textiles and other fields. Its skin-friendly properties are mainly reflected by the surface roughness of the film. Therefore, ensuring a low surface roughness of the film surface is one of the important parameters to ensure its skin-friendly nature.

[0003] The existing methods for detecting the surface roughness of thin films are mainly carried out through various high-end microscopes, such as optical microscopes, scanning electron microscopes and atomic force microscopes. These microscopes are cumbersome to operate during detection and are relatively expensive. Utility Model Content

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] See also Figures 1 to 4, the utility model embodiment includes:

[0019] A surface roughness detection device for skin-friendly thermoplastic polyurethane film includes a mounting structure and a rotation detection structure. The rotation detection structure is mounted on a table 12 for transmitting a film 11 through the mounting structure. The rotation detection structure can detect the surface roughness of the film 11 through friction. The structure is simple and the manufacturing cost is greatly saved.

[0020] The installation structure includes an intermediate bracket 1, four yielding brackets 2 and four locking brackets 3. The intermediate bracket 1 is arranged across the table 12. The four yielding brackets 2 are symmetrically arranged in groups of two on the vertical sections on both sides of the intermediate bracket 1 near the bottom end. The yielding brackets 2 are used to give way to the detection wheel 7 to prevent the locking plate 4 from being too high and affecting the installation of the rotating shaft 6.

[0021] A locking bracket 3 is installed horizontally and vertically at the development end of each of the yield brackets 2, and a locking plate 4 is connected to the locking bracket 3 via a locking bolt. The locking bolt is fixed to the bottom of the locking plate 4. A locking nut is installed after the locking bolt passes through the locking bracket 3. The locking bracket 3 is used for locking during installation so that the device can be fixed on the table 12.

[0022] The rotation detection structure includes a motor 5, a rotating shaft 6 and a plurality of detection wheels 7. The motor 5 is installed on the vertical section on the left side of the intermediate bracket 1 through a mounting seat. The rotating shaft 6 is installed between the two vertical sections through a bearing, and the left end is fixedly connected to the motor 5. The motor 5 is used to drive the rotating shaft 6 to rotate.

[0023] The size of the detection wheel 7 is selected according to the thickness of the film 11 so that the bottom of the detection wheel 7 contacts the upper surface of the film 11 .

[0024] A plurality of the detection wheels 7 are connected and installed on the rotating shaft 6 . A plurality of limiting edges 8 are provided on the rotating shaft 6 . The limiting edges 8 cooperate with the limiting grooves 9 starting from the middle of the detection wheels 7 , so that the detection wheels 7 can rotate together with the rotating shaft 6 .

[0025] The rotation direction of the motor 5 is opposite to the conveying direction of the film 11 , and a pressure sensor 10 connected to the signal of an external processing device is embedded in the side wall of the limiting groove 9 in the rotation direction of the motor 5 .

[0026] During detection, since the rotation direction of the motor 5 is opposite to the conveying direction of the film 11, when the friction between the detection wheel 7 and the film 11 increases, the rotation speed of the detection wheel 7 decreases, the pressure sensor 10 and the limiting edge 8 are relatively displaced, and the pressure detected by the pressure sensor 10 increases, indicating that the surface of the film 11 contacted by the detection wheel 7 has an increased roughness problem. When the increase range exceeds the range required by the film 11, the external processing equipment issues a non-conforming notification.

[0027] Since the limiting edge 8 is rotated at a constant speed by the motor 5, it can be regarded as relatively stationary. As long as each detection wheel 7 is subjected to different friction during rotation, resulting in different rotation speeds, the pressure data detected by the pressure sensor 10 will also be different, and the surface roughness condition of each position can be determined. The narrower the width of the detection wheel 7 and the greater the number, the greater the detection accuracy.

[0028] Different from the prior art, the utility model discloses a surface roughness detection device for a skin-friendly thermoplastic polyurethane film. The device adopts a rotating detection structure and can detect the surface roughness of the film by friction. The structure is simple and the manufacturing cost is greatly saved.
