Description

Technical Field

[0001] The utility model relates to the technical field of ton bag packaging hanging ear detection, in particular to a hook with a hanging ear detection mechanism. Background Art

[0002] When loading a ton bag, the four hanging ears of the ton bag will be hung. Because the ton bag has a large carrying capacity, once the hanging ear on one side is decoupled from the hook, the entire ton bag will tilt, causing the material in the ton bag to be poured out, resulting in a safety accident. Therefore, a hook with a hanging ear detection mechanism is designed. The pin sensor is used to detect the pressure borne by the hook and judge the stability of the hanging ear of the ton bag, thereby avoiding the situation where the hanging ear and the hook are decoupled during loading. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 1 The utility model provides a technical solution: a hook with a detection ear mechanism for ton bag packaging, including a square tube frame 1, a hook frame 3 is connected to the center of the square tube frame 1, a feed port is provided at the center of the hook frame 3, and the feed port is provided above the ton bag, and four hook seats 2 are fixed on the square tube frame 1, and the hook seats 2 are provided above the four corners of the ton bag. The lower end of the hook seat 2 is rotatably connected to the square tube 4 through the pin sensor 25, and the lower end of the square tube 4 is connected to the hook 42 through the pin. The hook 42 is used to hang the four ears of the ton bag, and the ears of the ton bag are hung by the hook 42, which increases the pressure on the hook 42 and the square tube 4, and increases the pressure on the pin sensor 25. The shear force of the hook seat 2 and the square tube 4 is detected by using the pin sensor 25 to detect the tension on the hook 42. By comparing the tension changes of the four pin sensors 25, it is confirmed whether the four hooks 42 have hooked the hanging ears of the ton bag, so as to judge whether the ton bag is hung in place and stably, and realize the detection of the hanging between the hook 42 and the hanging ear. When the forces on the four pin sensors 25 are basically the same, the hanging ears of the ton bag by the four hooks 42 are stable. When the force on a pin sensor 25 is significantly different from the force on other pin sensors 25, manual intervention is required to adjust the hanging ears on the hook 42 to make the hook 42 stably hook the ton bag.

[0021] like Figure 2 As shown, the hook seat 2 includes a top plate 21 and a bottom plate 23. The top plate 21 is located at the upper end of the square tube frame 1, and the bottom plate 23 is located at the lower end of the square tube frame 1. A connecting column 22 is connected between the top plate 21 and the bottom plate 23. A plug plate 24 is formed at the lower end of the bottom plate 23. Two vertical splints 43 are connected to the upper end of the square tube 4. The plug plate 24 is inserted between the two splints 43, and pin sensors 25 are inserted in the splints 43 and the plug plates 24. The pin sensors 25 are used to improve the connection strength between the splints 43 and the plug plates 24. At the same time, the splints 43 and the plug plates 24 can rotate around the center line of the pin sensor 25, thereby adjusting the rotation angle of the square tube 4, and rotating the hook 42 to hook it into the hanging ear of the ton bag, thereby improving the hooking efficiency of the hook 42.

[0022] A hook lifting cylinder 41 is hinged on the outer surface of the lower end of the square tube 4, and the output end of the hook lifting cylinder 41 is connected to the upper end of the hook 42. The telescopic control of the hook lifting cylinder 41 makes the hook 42 swing around the pin shaft, and adjusts the rotation angle of the hook 42 to facilitate the rotation of the hook 42 to disengage from the hanging ear or to rotate the hook 42 into the hanging ear.

[0023] like Figure 3 As shown, the lower end of the hook frame 3 is hingedly connected to a swing cylinder 7, and the output end of the swing cylinder 7 is connected to the side of the square tube 4. The inclination angle of the square tube 4 is adjusted by the extension and contraction of the swing cylinder 7, so that the square tube 4 rotates with the pin shaft sensor 25 as the axis.

[0024] The two sides of the feed port are rotatably connected with a clamping assembly 6, which includes a clamping arm 61 and a clamping claw 62. The clamping arm 61 is connected to the clamping claw 62, and the clamping arm 61 is rotatably connected to the surface of the feed port. The lower end of the hook frame 3 is also hinged with a discharge port cylinder 5, and the output end of the discharge port cylinder 5 is connected to the clamping claw 62. The swing of the clamping claw 62 and the clamping arm 61 is controlled by the telescopic control of the discharge port cylinder 5, so that the clamping claws 62 on both sides move inward together to clamp the upper opening of the ton bag to prevent the ton bag from loosening.

[0025] like Figure 4 As shown, the clamping jaw 62 includes an inner plate 621 and an outer plate 622 that are connected to each other. The two ends of the inner plate 621 and the outer plate 622 are connected together by fasteners. A bolt 623 is fixed to one side of the inner plate 621. A spring 624 is sleeved on the bolt 623. The spring 624 is located between the inner plate 621 and the outer plate 622. The upper opening of the ton bag is clamped by the clamping jaw 62. The outer plate 622 is pushed by the discharge port cylinder 5. Then the inner plate 621 is attached to the surface of the upper opening of the ton bag. As the outer plate 622 continues to apply pressure, the spring 624 is deformed, thereby generating elastic force on the inner plate 621, pressing the inner plate 621 completely on the surface of the upper opening, so that the upper opening is completely attached to the feed port, completing the clamping of the upper opening.

[0026] like Figure 1 As shown, a slide rail 8 is also fixed to the lower end of the square tube rack 1, and a slider 81 slides on the slide rail 8. The lower end of the square tube rack 1 is also connected and fixed with a telescopic cylinder 9, and a connecting block 91 is fixed to the output end of the telescopic cylinder 9. The connecting block 91 is connected to the slider 81, and the movement of the connecting block 91 is controlled by the telescopic movement of the telescopic cylinder 9 to further push the slider 81 to move on the slide rail 8. The slide rail 8 and the slider 81 are used to guide the movement of the connecting block 91. A strut 92 is fixed to the lower end of the connecting block 91. The outward movement of the strut 92 expands the upper opening of the ton bag, thereby facilitating the upper opening to be put on the feed port, thereby realizing the loading of the ton bag.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
