Description

Technical Field

[0001] The present invention relates to the field of production of container bag slings, and more particularly to a cutting and dotting machine for container bag slings. Background Art

[0002] After the container bag is loaded, usually two or four slings are sewn on the bag body for convenient lifting. The container bag sling is a load-bearing component connecting the container bag body and the lifting equipment, generally made of high-strength fiber materials such as polyester and nylon, and has high strength and flexibility; during the lifting and transportation process of the container bag sling, it can evenly disperse the weight of the goods in the container bag and transmit it to the lifting equipment, ensuring that the container bag can safely lift and transport several tons or even dozens of tons of goods. At the same time, it provides a connection point for the lifting equipment, facilitating the connection of equipment such as forklifts and cranes with the container bag sling through hooks and lifting tools, realizing the lifting, handling and loading / unloading operations of the container bag, and improving the efficiency of logistics transportation; during the lifting process of the container bag sling, through the slings reasonably distributed around the container bag, the balance and stability of the container bag and the goods it loads can be ensured, preventing the goods from tilting, shaking or even falling during the lifting process, and ensuring the operation safety.

[0003] During the production process of the container bag sling, cutting and dotting are required. Dotting refers to making marks on the sling so that the sewing worker can sew on the marks.

[0028] Working principle: Please refer to Figure 1 - Figure 12As shown, when the bulk bag sling cutting and dotting machine is in use, first, the bulk bag sling is wound around the outer side of the sleeve column 303, and the 4 sleeve columns 303 are sleeved on the front and rear ends of the outer side of the connecting column 302. A separating connecting ring 305 is placed between two adjacent sleeve columns 303. At the same time, the locking bolt 307 is tightened to fix the sleeve column 303 and the anti-disconnection connecting ring 304 on the outer side of the connecting column 302. When the bulk bag sling is cut and dotted, it rotates on the outer side of the sleeve column 303. Then, the bulk bag sling is passed through the conveying unit 4 and the guiding unit 5. The conveying roller 402 is driven to rotate by the first motor 401 to convey the bulk bag sling. Secondly, the rotating shaft 902 and the first driving gear 903 are driven to rotate by the fourth motor 901, so that the toothed bar 906 is driven to rotate, and the connecting seat 907 and the pneumatic gripper 908 are driven to move back and forth. The pneumatic gripper 908 clamps the rear end of the bulk bag sling and moves it backward. After it moves to the set length, the fourth telescopic cylinder 1009 pushes the pushing plate 1010 to move backward. The second telescopic cylinder 701 drives the pressing plate 702 to move downward, and the bulk bag sling is pushed between the two folding rollers 602, and a crease is pressed on the bulk bag sling on the downward pressing limiting plate 1011. Further, the third telescopic cylinder 1002 pulls the second connecting rod 1003, the moving seat 1004, the ultrasonic dotting head 1005 and the clamping plate 1006 to move forward, so that the clamping plate 1006 clamps the rear side of the bulk bag sling and the pushing plate 1010. The ultrasonic dotting head 1005 dots the bulk bag sling through the dotting hole 1007. Finally, the third motor 801 drives the threaded rod 802 to rotate, so that the moving block 803 and the laser cutting head 804 move, and the dotted bulk bag sling is cut. The pushing plate 1010 moves forward, and the clamping plate 1006 moves backward. At the same time, the second motor 601 drives the folding rollers 602 to rotate, and the cut and dotted bulk bag sling is folded and conveyed.
