[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: an automatic wrapping device for packing straps, including a frame 100, a platform 2 for lifting the packing straps is installed on the surface of the frame 100, two sets of supports 17 are installed on both sides of the surface of the frame 100, the two sets of supports 17 are arranged in parallel, and a turntable 1 7 and a turntable 2 9 for driving the packing straps to rotate are rotatably installed between the two sets of supports 17.

[0028] Both sets of brackets 17 are equipped with photoelectric switches 3 for detecting the inner edge of the packing strap. When the equipment is working, the two sets of photoelectric switches 3 shoot at each other. When the packing strap rises to a certain height, the center of the packing strap coincides with the center of the turntable, and the inner edge of the packing strap blocks the signal of the photoelectric switch 3, indicating that the packing strap has moved into place.

[0029] The turntable 29 is equipped with a pressing mechanism for fixing the front end of the packaging film to the strapping, which facilitates subsequent film wrapping. The frame 100 is also equipped with a material return mechanism for cutting off the packaging film. After the strapping rotates once, the packaging film completely wraps the strapping, and the material return mechanism cuts off the packaging film.

[0030] The bottom of the frame 100 is equipped with a lifting mechanism 1 that drives the platform 2 to rise and fall. The lifting mechanism 1 includes a motor 101 fixed on the frame 100, four sets of slides 104 installed on the inner side wall of the frame 100, and four sets of support frames 106 connected to the bottom of the platform 2.

[0031] The output shaft of motor 101 is connected to lead screw 102. The outer wall of lead screw 102 is threaded with H-shaped lifting plate 103. The bottom of four sets of support frames 106 are all connected to the lifting plate 103. The side of the support frame 106 is equipped with slide rail 105. The slide block 104 is slidably installed on slide rail 105.

[0032] Motor 101 drives lead screw 102 to rotate, which in turn drives H-shaped lifting plate 103 on lead screw 102 to rise, which in turn drives support frame 106 to rise, and support frame 106 drives platform 2 to rise, thereby lifting the packing strap.

[0033] One set of brackets 17 is equipped with cylinder 6, and turntable 7 is rotatably mounted on the piston end of cylinder 6; cylinder 6 drives turntable 7 to move and approach the packing strap after it is in place, and through the cooperation of turntable 7 and turntable 9, the packing strap is clamped and positioned.

[0034] Another set of brackets 17 has a rotating shaft 13 rotatably mounted on it, and a second turntable 9 is fixed to one end of the rotating shaft 13. The rotation of the rotating shaft 13 drives the second turntable 9 to rotate, which in turn drives the packing strap to rotate.

[0035] Another set of brackets 17 is also fixed with a mounting bracket, on which a second motor 8 is mounted. The output shaft of the second motor 8 is sleeved with a first gear 19, and the outer wall of the rotating shaft 13 is sleeved with a second gear 20. The first gear 19 and the second gear 20 mesh. The other end of the rotating shaft 13 is also connected to a rotary joint 12.

[0036] It is worth noting that the rotating shaft 13 has multiple channels inside. After the rotating shaft 13 is connected and cooperates with the rotary joint 12, the electrical equipment wiring will not get tangled or knotted during rotation.

[0037] The second motor 8 drives the rotating shaft 13 to rotate through the meshing of gear 19 and gear 20, which in turn drives the packing strap to rotate, and the packaging film begins to wrap around the packing strap.

[0038] The pressing mechanism includes a cylinder 16 fixed on a turntable 29 and a slide rail 26. One end of the piston rod of the cylinder 16 is connected to a slide block 25, and the slide block 25 is slidably mounted on the slide rail 26.

[0039] A cylinder 15 is also installed on the slide block 25. A rocker arm 14 is rotatably connected to the piston end of the cylinder 15. A telescopic column is rotatably installed between the outer shell of the cylinder 15 and the lower part of one end of the rocker arm 14.

[0040] Cylinder 3 16 is used to drive the swing arm 14 to extend and retract, so as to press and position the packing straps of different sizes and specifications. Cylinder 2 15 is used to drive the swing arm 14 to swing up and down, so as to easily introduce the front end of the packaging film onto the packing strap and align it with the packing strap. Then, cylinder 2 15 drives the swing arm 14 to swing down again, pressing it onto the packaging film, so as to fix the front end of the packaging film to the packing strap.

[0041] The unloading mechanism includes cylinder 4 21 and cylinder 5 23 mounted on the frame 100. One end of the piston rod of cylinder 4 21 is equipped with a cutter 22 for cutting the packaging film via a positioning frame. One end of the piston rod of cylinder 5 23 is equipped with a heating wire 24 for bonding the packaging film and the packing strap via a positioning frame.

[0042] Cylinder 4 21 drives the cutter 22 forward to cut the packaging film, and cylinder 5 23 drives the heating wire 24 forward to melt the cut position of the packaging film and bond it with the packing strap to achieve the wrapping treatment of the packing strap.

[0043] In use, place the packing strap to be coated on platform 2, run motor 101, motor 101 drives lead screw 102 to rotate, drive H-shaped lifting plate 103 on lead screw 102 to rise, thereby driving support frame 106 to rise, support frame 106 drives platform 2 to rise, thereby lifting the packing strap. When the packing strap moves to be aligned with the center of the two turntables, two photoelectric switches 3 are used to detect whether the packing strap has moved into place. When the inner edge of the packing strap blocks the signal of the photoelectric switch 3, it indicates that the packing strap has moved into place.

[0044] Cylinder 16 pushes turntable 17 to move, clamping the packing strap between turntable 17 and turntable 29 (the center of the packing strap is aligned with the center of the turntable). Then, cylinders 215 and 316 are operated. The piston end of cylinder 316 drives slide 25 to move, which in turn drives cylinder 215 and swing arm 14 to move to accommodate packing straps of different sizes. Then, the piston end of cylinder 215 drives swing arm 14 to swing (i.e., one end of swing arm 14 is raised), introducing one end of the packaging film onto the surface of the packing strap, so that the front end of the packaging film can be pressed and fixed to the packing strap by cylinder 215 driving swing arm 14 again.

[0045] Then, motor 28 is run, and through the meshing of gear 19 and gear 20, it drives the rotating shaft 13 to rotate, which in turn drives the packing strap to rotate. The packaging film begins to wrap around the packing strap. After the packing strap has rotated one revolution, the packaging film is cut off by the unloading mechanism.

[0046] Specifically, cylinder 4 (21) drives the cutter 22 forward to cut the packaging film, while cylinder 5 (23) drives the heating wire 24 forward to melt the cut portion of the packaging film and bond it to the strapping, thus wrapping the strapping. After these actions are completed, all cylinders and motors return to their original positions, ready for the next operation.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
