Description

Technical Field

[0001] This utility model relates to the field of edge-locking devices, and in particular to an edge-locking device for the production of plastic woven bags. Background Technology

[0002] In the packaging industry, woven plastic bags are widely used for packaging and transporting products such as grains, chemicals, and building materials due to their low cost, high strength, and abrasion resistance. Seam locking, a crucial process in the production of woven plastic bags, directly affects the bag's lifespan and loading safety. High-quality seam locking effectively prevents bag openings and leakage of contents, ensuring reliability during transportation.

[0003] The existing edge-locking device for producing plastic woven bags suffers from low needle and thread sewing efficiency and is prone to problems such as skipped stitches and broken threads during the sewing process, resulting in weak edge-locking. Although the hot melt bonding method improves efficiency, it requires extremely high temperature and pressure control. Excessive temperature can cause deformation and carbonization of the bag material, while insufficient temperature will result in weak adhesion and affect the quality of edge-locking. Therefore, the above-mentioned technical problems need to be solved. Utility Model Content

An ultrasonic seamless sewing machine 4 is fixedly installed at the top of the column 11. A positioning roller 10 is rotatably installed on the lower side of one side of the ultrasonic seamless sewing machine 4. It is movably installed on the rotating plate 3 through the column 11, and the ultrasonic seamless sewing machine 4 and the positioning roller 10 are fixed, which facilitates the efficient edge locking and guiding of the plastic woven bag. A fixing plate 12 is fixedly connected to the upper end of the rotating plate 3. An adjusting bolt 13 is installed in the middle of the fixing plate 12 through a threaded connection. The other end of the adjusting bolt 13 is rotatably engaged with one end of the limiting plate 14. Through the cooperation of the fixing plate 12, the adjusting bolt 13 and the limiting plate 14, it is easy to realize the limiting adjustment of the plastic woven bag.

[0021] In this utility model, the positioning mechanism includes a hinge plate 6 hinged to one side of the ultrasonic seamless sewing machine 4 via a fixing bolt 5. A vertical rod 7 is vertically fixed to one end of the hinge plate 6. A threaded groove is provided at the bottom of the rod 7, and a fixing block 9 is threadedly connected to the groove. A pressure roller 8 is rotatably mounted between the fixing blocks 9. The positioning mechanism, consisting of the hinge plate 6, the rod 7, the fixing blocks 9, and the pressure roller 8, combined with the hinged installation of the fixing bolt 5, facilitates precise positioning of the woven bag. An electric telescopic rod 16 is installed at the bottom of the rotating plate 3. The output end of the electric telescopic rod 16 passes through the rotating plate 3 and is fixedly connected to the bottom of the column 11. The electric telescopic rod 16 is powered by an electric motor at the bottom of the rotating plate 3. The telescopic rod 16 is connected to the column 11 to facilitate the height adjustment of the ultrasonic seamless stitcher 4; the rotating mechanism includes a gear ring 15 fixedly connected to the bottom of the rotating plate 3, a U-shaped positioning plate 17 fixedly connected to the bottom of the support plate 2 on one side of the gear ring 15, a servo motor 18 mounted on the U-shaped positioning plate 17, the output end of the servo motor 18 passing through the U-shaped positioning plate 17 and fixedly connected to the middle of one end of the drive gear, the drive gear is rotatably installed in the U-shaped positioning plate 17, and the drive gear meshes with the gear ring 15.

[0022] Working principle: When using this utility model, the position of the limiting plate 14 is adjusted by adjusting bolt 13 according to the material, thickness and edge-locking requirements of the woven bag. Then, the servo motor 18 is started, driving the drive gear to rotate. Due to the meshing between the drive gear and the gear ring 15, the rotating plate 3 rotates in the circular through-hole in the support plate 2, thereby rotating the rotating plate 3 to a position that is easy to operate. Then, according to the thickness of the woven bag, the electric telescopic rod 16 is started, and its telescopic end pushes the column 11 to rise or fall, adjusting the distance between the ultrasonic seamless sewing machine 4 and the woven bag. To ensure the welding head of the sewing machine accurately contacts the edge of the woven bag, the operator lays the plastic woven bag flat on the rotating plate 3. By loosening the fixing bolts 5 and adjusting the angle of the hinge plate 6, the operator aligns the upright 7 and the pressure roller 8 with the edge of the woven bag to be sewn, and presses the pressure roller 8 to press the edge of the woven bag. At this moment, the ultrasonic seamless sewing machine 4 is activated. Through high-frequency vibration, heat energy is generated to melt and fuse the plastic material at the edge of the woven bag, achieving seamless sewing. The positioning roller 10 is close to the edge of the woven bag to assist in guiding the woven bag to move in a straight line, ensuring the flatness and uniformity of the sewn edge.
