Description

Technical Field

[0001] The utility model relates to the technical field of woven bag compound equipment, in particular to a double-station ring opening machine. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used to package goods for easy transportation and storage. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns in the woven bag.

[0003] Because the woven bag is composed of multiple warp and weft yarns, the warp and weft yarns need to be sewn in a loop to form the shape of the woven bag. Sometimes, due to the thin nature of the woven bag body, the multi-layer woven fabric needs to be sewn in a loop. In the process of sewing the loop of the woven fabric, a sewing device is needed. The existing sewing device adopts the form of sewing, and it is necessary to sew the upper and lower sides of the woven fabric twice respectively, or rotate the woven fabric for one circle to complete the complete loop sewing. In addition, the woven bag mouth is easy to come off and is not firm when sewing with stitches. This sewing device has the problems of low loop sewing efficiency and poor sewing quality.

[0024] The beneficial effects of such a configuration are as follows: the utility model adopts a bidirectional welding structure to quickly sew the loop of the woven fabric, that is, the upper welding mechanism and the lower welding mechanism located on the upper and lower sides of the sleeve device respectively sew the upper and lower sides of the loop of the woven fabric by ultrasonic welding, and the complete loop suturing can be completed without rotating the woven fabric, and the welding suturing method is more firm, and has the advantages of high loop suturing efficiency and excellent quality.

[0026] The beneficial effects of such a configuration are as follows: the braided fabric is put on the sleeve joint formed by the left bracket and the right bracket, and the extension and retraction of the left bracket and the right bracket are controlled by the left support cylinder and the right support cylinder respectively. The retractable and adjustable sleeve joint can adapt to braids of different sizes. After the braid is sleeved, the left support cylinder and the right support cylinder are adjusted to further flatten the ring of the braid, making it easier for the welding device to weld the ring of the braid, and the welding quality of the flattened ring is better.

[0027] It is further configured that the frame 1 is provided with a first sliding component 12 and a second sliding component 13 with the same structure, the first sliding component 12 includes a horizontal telescopic cylinder 14, a slide rail 15 and a slider 16 slidably connected to the slide rail 15, the slider 16 reciprocates along the slide rail 15 through the horizontal telescopic cylinder 14, the first sliding component 12 and the second sliding component 13 are respectively installed at both ends of the first bagging mechanism 6, and the first bagging mechanism 6 reciprocates on the frame 1 through the first sliding component 12 and the second sliding component 13.
