Description

Technical Field

[0001] The utility model relates to the technical field of transportation and packaging, in particular to a screw-type automatic strap. Background Art

[0002] In the fields of modern industry, transportation and logistics, construction and building, shipping and fishing, industrial manufacturing, and automotive transportation, it is often necessary to stably and safely fix goods during the packaging and transportation processes. There are two commonly used tools on the market: the first is a ratchet tie-down; the second is a PP polypropylene packing strap.

[0003] However, a ratchet tie-down usually consists of a soft flat polyester woven strap, a ratchet, and a handle. When in use, the ratchet tie-down requires manual operation. First, the excess woven strap is retracted into the central shaft of the ratchet, and then the ratchet is rotated to tighten the strap. The operation is troublesome and time-consuming. Safety accidents such as finger pinching are likely to occur when the ratchet is tightened. In addition, the storage, storage, and management of the strap are relatively troublesome;

[0004] However, when using a PP polypropylene packing strap, operations such as tightening, heat-melting and bonding the head and tail for fixation, and shearing are carried out through an automatic strapping machine. The plastic packing strap used in this method is a consumable and is not recycled, resulting in relatively high long-term operating costs.

[0005] Therefore, the utility model proposes a screw-type automatic strap. Content of the Utility Model

[0006] The purpose of the utility model is to solve the disadvantages existing in the prior art and propose a screw-type automatic strap.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: a screw-type automatic strap, including a strap, a threaded rod is arranged on the strap, and a first mounting seat and a second mounting seat are arranged at the center of the threaded rod;

[0008] A turbine is arranged between the first mounting seat and the second mounting seat. Both sides of the turbine are provided with first bearings. The turbine is rotatably connected between the first mounting seat and the second mounting seat through the first bearings. The turbine and the first bearings are both sleeved on the threaded rod. A transmission shaft is arranged above the adjusting nut in the first mounting seat and the second mounting seat. One end of the transmission shaft above the turbine is provided with a worm. The other end of the transmission shaft penetrates through the first mounting seat and the second mounting seat, and a second block is arranged on the transmission shaft.

[0009] As a preferred implementation manner, the second mounting seat is provided with a first bolt penetrating through the first mounting seat. There are six first bolts in total, and the six first bolts are distributed in a rectangular shape.

[0010] The beneficial effects of adopting the above further solution are as follows: The first mounting seat and the second mounting seat are of a split structure, and the first mounting seat and the second mounting seat are connected and fixed by a first bolt. The advantage of this structure is that when replacing the internal parts, the first bolt can be removed to separate the first mounting seat from the second mounting seat, so as to facilitate the maintenance and replacement of the internal parts.

[0011] As a preferred embodiment, a positioning pin is embedded and installed between the first mounting seat and the second mounting seat. A total of four positioning pins are provided, and the four positioning pins are distributed in a rectangle.

[0012] The beneficial effects of adopting the above further solution are as follows: The positioning pin is used to position between the first mounting seat and the second mounting seat, preventing the first mounting seat and the second mounting seat from rotating and misaligning during use, thereby improving the sealing performance between the first mounting seat and the second mounting seat.

[0013] As a preferred embodiment, second bearings are provided at both ends of the transmission shaft, and the transmission shaft is rotatably connected between the first mounting seat and the second mounting seat through the second bearings.

[0014] The beneficial effects of adopting the above further solution are as follows: The second bearings are provided so that the transmission shaft can be rotatably connected between the first mounting seat and the second mounting seat. And since the transmission shaft and the turbine are meshed, the turbine will rotate when the transmission shaft rotates.

[0015] As a preferred embodiment, both ends of the threaded rod are of a reverse and forward thread structure. The middle section of the threaded rod is a cylindrical smooth shaft and is provided with a slot. Tooth hole positions are provided at both end faces of the threaded rod. A groove is opened at the center of the turbine, and a first block is provided between the groove on the turbine and the groove opened on the threaded rod.

[0016] The beneficial effects of adopting the above further solution are as follows: The first block is fixed through the slot opened on the threaded rod and the groove opened at the center of the turbine, so that one side of the first block driven by the turbine rotates into the slot during use, and the first block and the slot are clamped with each other, so that the turbine can drive the threaded rod to rotate during rotation, thereby adjusting the tightness of the strap.

[0017] As a preferred embodiment, adjusting nuts are provided at both ends of the threaded rod. Limiting pieces are provided on the other sides of the two adjusting nuts. A second bolt is provided on the limiting piece, and a third bolt connected to the threaded rod penetrates through the second bolt.

[0018] The beneficial effects of adopting the above further solution are as follows: Through the design of the adjusting nut and the limiting piece, the structure and the strap are of a split structure, and during use, the threaded rod can be installed and fixed to the strap according to the length of the strap.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0030] As Figures 1-5 shown, the present invention provides a technical solution: a screw-type automatic strap, including a strap 17, on which a threaded rod 1 is provided. At the center of the threaded rod 1, a first mounting seat 10 and a second mounting seat 11 are provided; a turbine 2 is arranged between the first mounting seat 10 and the second mounting seat 11. On both sides of the turbine 2, a first bearing 6 is provided. The turbine 2 is rotationally connected between the first mounting seat 10 and the second mounting seat 11 through the first bearing 6. Both the turbine 2 and the first bearing 6 are sleeved on the threaded rod 1. Above the adjusting nut 5 in the first mounting seat 10 and the second mounting seat 11, a transmission shaft 7 is provided. At one end of the transmission shaft 7 above the turbine 2, a worm 3 is provided. The other end of the transmission shaft 7 penetrates through the first mounting seat 10 and the second mounting seat 11. On the transmission shaft 7, a second catch 8 is provided. On the second mounting seat 11, a first bolt 14 penetrating through the first mounting seat 10 is provided. There are six first bolts 14 in total, and the six first bolts 14 are distributed in a rectangle. At both ends of the transmission shaft 7, a second bearing 9 is provided. The transmission shaft 7 is rotationally connected between the first mounting seat 10 and the second mounting seat 11 through the second bearing 9. The two ends of the threaded rod 1 are of a reverse-thread structure. The middle section of the threaded rod 1 is a cylindrical smooth shaft with a slot, and the end faces of the two ends of the threaded rod 1 are provided with threaded hole positions. A groove is opened at the center of the turbine 2. A first catch 4 is arranged between the groove on the turbine 2 and the groove opened on the threaded rod 1. By rotating the transmission shaft 7 to drive the worm 3 to rotate, since the worm 3 and the turbine 2 are in meshing connection, during the rotation process, the rotation shaft of the turbine 2 is driven, and the first catch 4 is fixed through the slot opened on the threaded rod 1 and the groove opened at the center of the turbine 2, so that during use, one side of the first catch 4 driven by the turbine 2 rotates into the slot, and the first catch 4 and the slot are mutually clamped, so that the turbine 2 can drive the threaded rod 1 to rotate during the rotation process, thereby adjusting the strap 17 to any position and stopping, solving the technical problem of transportation and packaging.

[0031] Furthermore, as Figure 3 - Figure 4As shown in the figure: both ends of the threaded rod 1 have left - hand and right - hand thread structures. The middle section of the threaded rod 1 is a cylindrical smooth shaft with a slot. The end faces of both ends of the threaded rod 1 are provided with threaded holes. A groove is opened at the center of the turbine 2. A first clamping block 4 is arranged between the groove on the turbine 2 and the groove opened on the threaded rod 1. Adjusting nuts 5 are arranged at both ends of the threaded rod 1. Limiting plates 12 are arranged on the other sides of the two adjusting nuts 5. A second bolt 15 is arranged on the limiting plate 12. A third bolt 16 connected to the threaded rod 1 penetrates through the second bolt 15. Through the design of the adjusting nut 5 and the limiting plate 12, the structure is a split - type structure with the strap 17. During use, according to the length of the strap 17, the threaded rod 1 and the adjusting nut 5 can be quickly installed and fixed through the limiting plate 12, thus improving the practicability of the device and solving the technical problem of the device installation.

[0032] In the above - mentioned solution, there is also a problem of misalignment displacement between the first mounting seat 10 and the second mounting seat 11, as Figure 5 shown: in this solution, a positioning pin 13 is embedded and installed between the first mounting seat 10 and the second mounting seat 11. A total of four positioning pins 13 are provided, and the four positioning pins 13 are distributed in a rectangle. The first mounting seat 10 and the second mounting seat 11 are positioned by the positioning pin 13 to prevent rotational misalignment between the first mounting seat 10 and the second mounting seat 11 during use, thereby improving the stability between the first mounting seat 10 and the second mounting seat 11.

[0033] In this embodiment, a robotic arm is installed on the transmission shaft 7. The first mounting seat 10 and the second mounting seat 11 are grabbed by the robotic arm, and the output end of the power part on the robotic arm is connected to the transmission shaft 7.

[0034] In the present utility model, the strap 17 is composed of a flat metal strip and mounting seats welded to both ends of the metal strip.

[0035] Working principle:

[0036] As Figures 1-5 shown, first, the adjusting nut 5 is installed on the mounting seats at both ends of the strap 17 through the second bolt 15. Secondly, the box to be packed is placed inside the bandage 17, and the power part of the robotic arm is turned on. When the transmission shaft 7 rotates, the worm 3 on the transmission shaft 7 moves synchronously with the transmission shaft 7, driving the turbine 2 meshing with the worm 3 to rotate. The turbine 2 drives the threaded rod 1 to rotate synchronously. The transmission nuts at both ends of the threaded rod 1 drive the strap 17 to tighten or loosen. When the strap 17 is tightened to the appropriate position, the power part stops rotating, and the strap 17 will stop at the tightened position at this time, so as to adjust the tightness during packing as needed.

[0037] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
