Description

Technical Field

[0001] The utility model relates to the technical field of material packaging, in particular to a combined automatic binding belt. Background Art

[0002] In modern industry, transportation and logistics, building and construction, shipping and fisheries, industrial manufacturing, and automobile transportation, it is often necessary to stably and safely fix goods during packaging and transportation. There are two commonly used tools on the market: the first is ratchet strapping; the second is PP polypropylene strapping.

[0003] In actual use, the following deficiencies still exist. For example, ratchet straps typically consist of a soft, flat polyester webbing, a ratchet, and a handle. During use, ratchet straps require manual operation, requiring the excess webbing to be retracted into the ratchet's central axis before the ratchet is rotated to tighten the strap. This operation is cumbersome and time-consuming, and can easily lead to safety accidents such as pinching fingers when tightening the ratchet. Furthermore, the straps are difficult to store and manage.

[0004] When using PP polypropylene strapping tape, the automatic strapping machine is used to tighten, hot-melt bond the head and tail, and cut the tape to achieve bundling and packaging. The plastic strapping tape used in this method is a consumable and cannot be recycled, so the long-term operating cost is high.

[0005] Therefore, the utility model proposes a combined automatic binding belt to solve the above problems. Utility Model Content

[0030] 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.

[0031] like Figures 1-4 As shown, this embodiment provides a technical solution: a combined automatic strap, including a strap 3, a magnetic head assembly 1 is provided on the strap 3, and a magnetic cover assembly 2 is provided on the side of the strap 3 close to the magnetic head assembly 1;

[0032] like Figure 1-Figure 3 As shown, the magnetic head assembly 1 includes a magnetic base 11, a spring pin mounting seat 12 is provided in the magnetic base 11, a spring pin shaft 13 is fixedly connected to the spring pin mounting seat 12, a spring pin spring 14 is fixedly connected to the spring pin shaft 13, a support pad 15 is provided in the magnetic base 11, a compression spring 111 is provided on the support pad 15, a strong magnetic block 112 is fixedly connected to the compression spring 111, and a first bolt 113 is threadedly connected to the strong magnetic block 112;

[0033] like Figure 1-Figure 2 as well as Figure 4As shown, the magnetic cover assembly 2 includes a metal cover 21, a guide thread bearing 22 is provided on the metal cover 21, and a demagnetization pin 23 is fixed on the metal cover 21. Through the coordinated use of the magnetic head assembly 1 and the magnetic cover assembly 2, this technical solution achieves a fast, simple and safe bundling effect. In the magnetic base 11, the design of the spring pin mounting seat 12, the spring pin shaft 13 and the spring pin spring 14 makes it possible to automatically align and fix the strap 3 during use, greatly improving the convenience of operation. At the same time, the setting of the compression spring 111 and the strong magnetic block 112 on the support pad 15 ensures sufficient magnetic attraction, which can be firmly adsorbed on the metal cover 21, effectively preventing it from falling off due to vibration or external force. In addition, the design of the guide thread bearing 22 and the demagnetization pin 23 on the metal cover 21 further facilitates the bundling and unbundling operations, and improves the overall work efficiency. In summary, this technical solution solves the technical problem of safe and efficient bundling through the clever combination and interaction of various components.

[0034] The above solution still has the problem that when the straps are used to tie the items together, they cannot be untied quickly and safely. Figure 1-Figure 3As shown: a strap mounting seat 16 is fixed on the magnetic base 11, and a strap tightening shaft 17 is rotatably connected to the strap mounting seat 16. Through the strap mounting seat 16 on the magnetic base 11 and the rotatably connected strap tightening shaft 17, this technical solution realizes the rapid installation and convenient adjustment of the strap 3. The strap tightening shaft 17 can be rotated to tighten or loosen the strap 3, making the bundling process simpler and more efficient. This design allows the length of the strap 3 to be flexibly adjusted as needed to adapt to the bundling of goods of different sizes, thereby improving the convenience and adaptability of use. A ratchet 18 is provided on the strap tightening shaft 17. A retaining spring 115 is provided on one side near the ratchet 18. The design of the ratchet 18 and the retaining spring 115 on the strap tightening shaft 17 realizes the self-locking function of the strap 3. The ratchet 18 can provide a reliable lock to prevent the strap 3 from accidentally loosening during the bundling process. The retaining spring 115 ensures the stability of the ratchet 18, making the entire bundling process safer and reducing the risk of accidents caused by the loosening of the strap 3 during transportation or storage of goods. A rotating spring 110 is fixedly connected to the strap mounting seat 16, and the other end of the rotating spring 110 is fixedly connected to the ratchet 19. A second threaded spring 110 is connected to the strap mounting seat 16. The second bolt 114, through the use of the rotating spring 110 and the ratchet 19 on the strap mounting seat 16, realizes the precise adjustment and stable locking of the length of the strap 3. The rotating spring 110 provides elastic force for the ratchet 19, so that it engages with the ratchet 18 on the strap tightening shaft 17, thereby reliably fixing the length of the strap 3. The second bolt 114 is used to stably connect the rotating spring 110 and the ratchet 19 to the strap mounting seat 16, ensuring the stability and durability of the entire adjustment mechanism, and improving the safety and convenience of the binding operation. The ratchet 19 is threadedly connected with a third bolt 116, and the strap mounting seat 1 6 is fixed with a tripping top pin 117, and the strap mounting seat 16 is threadedly connected with a first machine-meter bolt 118. The third bolt 116 on the ratchet 19 and the tripping top pin 117 on the strap mounting seat 16 and the first machine-meter bolt 118 realize the quick untying function of the strap 3. The tripping top pin 117 can be used to push the ratchet 19 to disengage it from the engagement with the ratchet 18 on the strap tightening shaft 17, while the third bolt 116 ensures the stability of the ratchet 19, and the first machine-meter bolt 118 provides additional fixation for the entire mechanism, ensuring the reliability and convenience of the operation, making the untying process quick and safe.

[0035] like Figure 1-Figure 2 as well as Figure 4 As shown, the metal cover 21 is fixed on the strap 3, and a second machine screw 24 is threadedly connected to the metal cover 21. By fixing the metal cover 21 on the strap 3 and using the second machine screw 24 for threaded connection, a firm combination of the magnetic cover assembly 2 and the strap 3 is achieved. This design ensures the stability and durability of the magnetic cover during use, and improves the safety and reliability of the entire bundling system.

[0036] Working principle:

[0037] like Figures 1-4 As shown, this solution requires a robotic arm equipped with a specific clamp. Before use, fix one end of the strap 3 on the magnetic cover, and pass the other end through the opening on the strap tightening shaft 17 on the magnetic head. Rotate the strap tightening shaft 17 to roll it into the strap 3 for pre-locking. The magnetic head and magnetic cover are fixed on both ends of the clamp respectively. When in use, first place the center of the strap 3 on the bottom of the wooden pallet. After the goods are placed on the wooden pallet, the clamp brings the magnetic head and magnetic cover concentrically together. During the process of approaching, the cover is sucked. The guide thread bearings 22 on the magnetic head are aligned in the grooves on both sides of the magnetic base 11 of the magnetic head, playing a role of guiding and positioning. The magnetic cover continues to move closer, and the magnetic cover presses the spring pin on the magnetic head. The spring pin is compressed inward until the two are close together and the spring pin aligns with the through hole on the metal cover 21 of the magnetic cover and automatically pops up. At this time, the two are installed in place and the magnet on the magnetic head attracts the metal cover 21 on the magnetic cover. The magnetic head and magnetic cover are combined together, and the locking tool on the clamp is inserted into one end of the strap tightening shaft 17. The locking hole drives the strap tightening shaft 17 to rotate, and the strap 3 rotates with the strap tightening shaft 17, and is rolled up to fit the outer diameter of the strap 3 rotating shaft. The strap 3 is tightened, and finally the clamp is disengaged, and the robotic arm moves away to complete the tightening action of the strap 3. In this solution, during the transportation process, the spring pin provides a safety for the automatic strap 3 to prevent it from falling off due to vibration. When it needs to be untied, the robotic arm sends the clamp to the designated position, and the two ends of the clamp clamp the magnetic head and magnetic cover of the strap 3 respectively. The internal device of the clamp pushes down first Insert the spring pins on both sides to the spring pin shaft 13 of the spring pin to the lowest point, and then press the demagnetization top pin 23 of the magnetic cover to force the magnetic head and the magnetic cover to separate, completing the tripping action. After the robotic arm moves the magnetic head and the magnetic cover to the specified position, release the clamp. At this time, the untying action is completed. Before it needs to be used again next time, it is necessary to move the third bolt 116 on the ratchet 19 to make the ratchet 19 rotate around the second bolt 114, the ratchet 19 and the ratchet wheel 18 are disengaged, and the strap 3 is pulled out to a suitable length.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
