Abstract
Description
Technical Field
[0001] This utility model relates to the field of woven bag production, and in particular to a plastic woven bag edge-sealing device. Background Technology
[0002] Currently, in the production of woven bags, in order to ensure the strength of the edges, extend the service life of the bags, and better adapt to the convenience of later use, edge binding is required at the opening of the bags. This is usually done by sewing strips of fabric around the bag opening. Most existing sewing methods rely on manual sewing, where the sewing machine is operated manually, and the speed at which the bag is dragged affects the precision and strength of the edge binding. Due to differences in worker skill and fatigue from prolonged work, significant problems arise in the edge binding process, such as loose threads and peeling edges, seriously affecting product quality and sales.

The woven bag is fitted onto the roller, and the edge-binding of the woven bag is completed by the rotation of the roller and its cooperation with the sewing device. The operation is more stable and the edge-binding quality is higher.
[0005] A further technical solution of this utility model is: a drive motor is provided inside the mounting beam. The drive motor is located inside the mounting beam and drives the roller while also connecting the roller.

[0008] A further technical solution of this utility model is: a negative pressure machine is provided inside the inner cylinder to provide negative pressure so that the woven bag and the roller are tightly attached, thereby improving the edge binding quality.
[0009] A further technical solution of this utility model is: both the inner cylinder and the outer cylinder are provided with through holes, through which the woven bag placed on the outer cylinder is adsorbed.
[0010] A further technical solution of this utility model is: the side of the binding tape is provided with a guide ring and a cutting blade. The guide ring is used to guide the direction of the binding tape, and the cutting blade cuts the binding tape after the binding of a woven bag is completed.
[0011] The beneficial effects of this utility model are as follows: The plastic woven bag edge-binding device of this utility model has a simple structure, the woven bag is firmly adsorbed and has strong stability. The edge-binding is carried out during the uniform rotation of the motor-driven roller, the speed is stable, the stitching is uniform, the edge-binding efficiency is greatly improved, and the product quality is effectively guaranteed.
