Description

A coating device for the production of yoga mat fabric

technical field

The invention relates to the field of fabric production devices, in particular to a coating device for yoga mat fabric production.

Background technique

At present, people pay more and more attention to the quality and touch of yoga mat fabrics. In most cases, the fabric needs to be surface-coated during the production process. However, the coating effect of traditional fabric coating equipment is not ideal. In the coating process, dry coating is often used. The surface of the fabric is coated by the coating roller, so that the surface of the fabric is attached with a specific coating agent, and then dried to form a functional coating. However, in the coating process Firstly, the reagent is applied to the coating roller by a scraper, and then coated by the coating roller. During the production process, the surface of the scraper is prone to adhered impurities or gaps, resulting in an axial defect in this coating position. It is easy to form strip-shaped coating defects on the surface of the fabric, forming a thin or uncoated situation, resulting in a significant decrease in the functionality of the fabric at this position, affecting the use of the fabric.

The invention of patent No. CN212943602U provides a kind of equipment to solve the above problems. The method of oblique coating roller is used to coat the fabric horizontally and vertically to avoid defects, but because the oblique coating roller will rub the fabric, The trajectory of the fabric is changed. In order to solve the above problems, a large number of devices have been added to prevent such problems. However, the angle between the coating rollers will still make the coating uneven, and the setting effect of other devices is still not ideal. And it makes the equipment structure complicated, troublesome to control, difficult to maintain, inaccurate in precision and so on.

When the fabric passes through the first coating assembly 110, the first coating roller 210 and the second coating roller 220 of the first coating assembly 110 below the fabric are dipped into the first material storage chamber and the second storage chamber during rotation. The liquid in the material cavity, the inclined first coating roller 210 in the first coating assembly 110 makes the fabric have a tendency to move to the right, and the inclined second coating roller 220 in the first coating assembly 110 makes the fabric have a leftward movement tendency. The movement trend of the fabric, the influence of the second coating roller 220 and the first coating roller 210 in the first coating assembly 110 on the movement of the fabric in the width direction cancels each other out. However, the gap between the hinge of the first coating roller 210 and the second coating roller 220 in the first coating assembly 110 cannot evenly coat the material. Because the hinge shaft of the first hinge block 310 between the first coating roller 210 and the second coating roller 220 of the first coating assembly 110 is fixedly arranged on the left side of the midline of the fabric width. The hinge shaft of the first hinge block 310 between the first coating roller 210 and the second coating roller 220 of the second coating assembly 120 is fixedly arranged on the right side of the midline of the fabric width. During recoating by the second coating assembly 120, the defects of the fabric coated by the first coating assembly 110 are compensated, so that the fabric is coated more uniformly.

When coating materials with different widths, the two bending rods 440 are far away from each other, and the materials are always in the middle of the detection slide rail 430, the first driving rod 250 is fixedly provided with the first guide rod 450, and the second driving rod 260 is fixedly provided with a second guide rod 460, and one end of the two bending rods 440 slides along the first guide rod 450 and the second guide rod 460, and when the bending rod 440 slides laterally along the detection slide rail 430, the first A driving rod 250 slides along the first slideway 242 and a second driving rod 260 slides along the second slideway 243 to gradually increase the angle between the first coating roller 210 and the second coating roller 220 . The angle between the first coating roller 210 and the second coating roller 220 decreases synchronously with respect to the transverse direction of the fabric, and the second coating roller 220 and the first coating roller 210 in the first coating assembly 110 increase the width The influence of the movement of the fabric in the width direction cancels each other out, and the second coating assembly 120 compensates for the gap defects produced by the coating of the fabric by the first coating assembly 110, so that the two sets of coating assemblies are suitable for coating fabrics with different specifications and widths. cover.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
