Description

Technical Field

[0001] The invention relates to the technical field of roller blind fabric coating, and in particular to a roller blind fabric coating machine and a coating process for avoiding blockage. Background Art

[0002] In the field of textile and coating industry, coating treatment of roller blind fabrics is a key step to increase product added value and enhance fabric functionality and aesthetics.

[0003] The reference patent (publication number: CN216605906U; publication date: 2022-05-27) discloses a fabric coating machine with uniform coating, which belongs to the field of fabric processing. The fabric coating machine includes a coating roller, a tensioning unit provided with a cloth guide roller, and a frame carrying the above components. The frame is respectively provided with a jacking mechanism on both sides in the width direction, and the output end of the jacking mechanism is hinged to the tensioning unit. A grating door is provided before the tensioning unit along the travel order of the fabric on the frame. The jacking mechanism and the grating door are electrically connected to a controller. The grating door is used to monitor the thickness of the fabric in real time. If it is monitored that the thickness of the fabric continues to increase, that is, the left and right sides of the fabric are not at the same height, the controller controls the jacking mechanism to rise or fall, and actually adjusts the height of the two ends of the cloth guide roller so that the fabric thickness monitored by the grating door is restored to the preset value. Even if the two sides of the fabric are at the same height, the fabric coating is uniform in the direction of fabric travel, while ensuring that the coating thickness on the left and right sides of the fabric is consistent, which is beneficial to improving the finishing quality of the fabric.

[0004] In the coating process of traditional coating machines, due to improper control of fabric tension, wrinkles and bubbles are easily caused on the fabric, affecting the aesthetics and durability of the coating. In addition, the raw materials are prone to sedimentation and agglomeration after being left standing for a long time, affecting the smoothness of the discharge and the uniformity of the coating, and are prone to blockage. Then, the coating shaft is prone to rolling with agglomerated raw materials, which not only affect the uniformity of the coating, but also may block the micropores on the coating shaft, resulting in coating interruption or uneven thickness. For this reason, the present invention provides a roller blind fabric coating machine and a coating process that avoids blockage.
