Description

Technical Field

[0001] This utility model relates to the field of seamless underwear production technology, specifically to an adhesive device for seamless underwear production. Background Technology

[0002] In the field of seamless underwear production, traditional sewing processes are prone to problems such as seam protrusions and discomfort when wearing, which affect product quality and user experience. As consumers' requirements for underwear comfort and fit increase, bonding technology is gradually replacing traditional sewing. However, existing bonding devices for seamless underwear production have defects such as uneven bonding, low efficiency, and complicated operation, which make it difficult to meet the needs of large-scale, high-quality production and urgently need to be optimized and improved.

[0003] Seamless underwear fabric is soft, and if it is not held in place during adhesive application, it is prone to wrinkles and shifting. This can lead to unstable distances between the adhesive applicator and the fabric, uneven adhesive application, and areas with too much or too little adhesive. This can cause problems with the subsequent bonding process of the underwear, affecting production efficiency. Utility Model Content

The device includes a glue storage tank and a glue pump installed inside the glue application head. A retractable glue delivery pipe is installed between the glue pump and the glue storage tank. A through-hole is provided at the center of the top of the first lifting frame. When the underwear is being glued, it is placed on the surface of the conveyor belt. The first servo motor is started according to the size of the underwear, driving the first bidirectional screw to rotate and causing the first slider to move in opposite directions. Then, the first lifting frame, the first electrically controlled lifting column, and the second electrically controlled lifting column are lowered. The silicone clamping block presses down on both ends of the glue application area of ​​the underwear to prevent the underwear from moving during the glue application process.

The staff first adsorbs the underwear at the other end through the adsorption head and the air extraction box. After the underwear at the bottom end is in place, the second lifting frame is lowered to stick the underwear at both ends together. Then the fourth electrically controlled lifting column is lowered, and the hot press plate is heated by the electric heating tube. The hot press plate presses and bonds the underwear. After bonding, the underwear can be quickly cooled and formed by the drying fan.

Then, the first lifting frame, the first electrically controlled lifting column, and the second electrically controlled lifting column are lowered. The silicone pressing block presses down on both ends of the underwear at the glue application area to prevent the underwear from moving during the glue application process. The glue pump is activated to allow the glue to flow from the glue storage tank to the glue application head for the glue application operation. This mechanism ensures that the underwear does not move unnecessarily during the glue application process, and the glue application area of ​​the underwear remains flat to prevent wrinkles from affecting the glue application work. This device can ensure that the glue is evenly applied to the fabric surface, improve the bonding quality, and ensure the consistency of the underwear's size and shape before and after glue application, laying a good foundation for subsequent bonding and molding processes.
