Industrial zipper stitching process for drying net opening

Abstract

The invention discloses an industrial zipper stitching process for a drying net opening. The process comprises the following steps: flatly spreading a drying net, and fixing the end parts of the drying net to a panel workbench by utilizing strong magnetic fixing blocks; installing a sewing machine support onto a sliding rail, fixing an industrial sewing machine onto the sewing machine support, andplacing a power line of the industrial sewing machine into a drag chain type conductor groove; placing an industrial zipper and spiral ring interfaces in parallel, and stitching the industrial zipperand the spiral ring interfaces onto a drying net body by using the industrial sewing machine; and after the industrial zipper is pulled, enabling a ring interface passing thread to pass through the interfaces in sequence. The stitching process provided by the invention is simple and has high operability, and the stitched drying net forms an endless cylinder shape, so that damage and breakage of atraditional interface connecting ring and a wrinkle phenomenon of the net body are effectively avoided; and in the stitching process, a sliding speed is set through a variable-frequency motor according to stitching specifications required by the drying net, and the process adapts to more demand while realizing fast and high-efficiency stitching.

Description

technical field [0001] The invention belongs to the technical field of dry net manufacturing, and in particular relates to an industrial zipper sewing process for a net mouth of a dry net. Background technique [0002] The replacement of the dry felt by the dry wire in the drying section of the paper machine has played a huge role in saving energy consumption and increasing production capacity. Now, except for some small machines that produce special paper with low grammage and low speed, paper companies generally use various types of Dry net. Due to the wide and long page width and the heavy weight of the net body, the dry wire used for high-speed and wide-width paper machines can no longer use the terminal interface. When the situation happens, sometimes the network will wrinkle. When the end interface is connected, the threading work of the ring interface is more difficult. Sometimes it takes more than ten hours or even longer to thread a network sub-interface, causing g...

Due to the wide and long page width and the heavy weight of the net body, the dry wire used for high-speed and wide-width paper machines can no longer use the terminal interface. When the situation happens, sometimes the network will wrinkle. When the end interface is connected, the threading work of the ring interface is more difficult. Sometimes it takes more than ten hours or even longer to thread a network sub-interface, causing great losses; the traditional end interface can no longer Widely adapted to the market
