Description

Technical Field

[0001] This utility model belongs to the field of insulated bag sewing technology, and in particular relates to a sewing device for a takeaway insulated bag production line. Background Technology

[0002] Insulated food delivery bags are packaging containers used in food delivery to maintain the temperature of the food and ensure its taste during delivery. Insulated bags often use a multi-layer composite structure, mainly consisting of an inner insulation layer and an outer wear-resistant layer, which can block the conduction of heat.

[0003] In the production process of thermal insulation bags, the insulation layer and the wear-resistant layer need to be sewn together, so a sewing device is used. The overall sewing device includes a conveying component and a sewing machine. The conveying component mainly supports and conveys the rolled raw materials of the insulation layer and the wear-resistant layer. Then, one end of the insulation layer and the wear-resistant layer passes through the sewing machine and the external rollers. The rotation of the rollers can drive the insulation layer and the wear-resistant layer to move. When using it, it is necessary to ensure that the conveying component and the rollers are parallel to each other, and to ensure that the outer edges of the insulation layer and the wear-resistant layer are aligned during conveying, so as to reduce the uneven sewing caused by misalignment of the outer edges. Since there is no synchronous control mechanism between the conveying component and the rollers, when sewing thermal insulation bags of different widths, the operator needs to adjust the position of the conveying component and the rollers back and forth, which is relatively troublesome to use.

[0004] In view of this, we propose a sewing device for a takeaway insulated bag production line. Utility Model Content
