Description

Technical Field

[0001] The invention relates to the technical field of fabric production equipment, and in particular to a coating device for producing yoga mat fabrics. Background Art

[0002] Yoga mats are the mats you lay on when practicing yoga. The materials of yoga mats are generally divided into TPE foam, PVC foam, EVA, latex mats, CBR mats, etc. At present, people pay more and more attention to the quality and touch of yoga mat fabrics. In most cases, the fabrics need to be surface coated during the production process.

[0003] After searching, the publication number is CN115301502B, which is a coating device for producing yoga mat fabrics. The invention relates to the field of fabric production devices, and specifically to a coating device for producing yoga mat fabrics. A coating device for producing yoga mat fabrics includes a tensioning component, a coating component and a detection component. After the detection component detects the width of the fabric, the inclination angle between the two first coating rollers and the fabric, and the inclination angle between the two second coating rollers and the fabric are adjusted. The effects of the second coating roller and the first coating roller on the width direction movement of the fabric offset each other, so that the fabric maintains stable length direction movement. The hinge shafts of the first coating roller and the second coating roller of the two sets of coating components are on both sides of the fabric width center line, and the opening directions of the first coating roller and the second coating roller of the two sets of coating components are opposite. After the two sets of coating components coat the fabric, the gap between the first coating roller and the second coating roller is filled, and the coating of the fabric is more uniform and complete.

[0004] In the above scheme, only the opening directions of the two groups of coating components are set in opposite directions, and the fabric is coated by the two groups of coating components, so that the gap between the first coating roller and the second coating roller is filled, and the coating of the fabric is more uniform and complete. It is not considered that when the coating device is coating the fabric, the coating is often incomplete due to wrinkles on the fabric, which greatly affects the quality of the product; and the coating required for fabric coating often needs to be stirred and mixed during configuration, so smaller bubbles will be entrained in the coating, and the presence of these bubbles will cause pits on the surface of the fabric and uneven coating; therefore, the present application scheme proposes a coating device for yoga mat fabric production to solve the above problems.
