Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bag technology, specifically a fastener for plastic packaging straps. Background Technology

[0002] Plastic strapping, also known as plastic bundling strap, is a strip-shaped material made primarily of plastic used for bundling and packaging items. Plastic bundling straps are typically produced through processes such as extrusion unidirectional stretching and heat treatment bluing. During the packaging process, after the plastic strapping is used to tighten the items, it needs to be connected and fixed in a suitable way to ensure the strength of the packaging. Usually, disposable fasteners are used for connection, or the overlapping ends of the strapping are heated and welded together, so that the box is neat and stable, making it easy to handle and transport.

[0003] However, while existing fasteners for plastic packaging straps can secure the straps, removing them usually requires destructive methods such as cutting. The cut plastic packaging straps and disposable fasteners are then discarded, increasing packaging costs. Therefore, we provide a fastener for plastic packaging straps. Utility Model Content

The sides of the two sets of limiting blocks that are close to each other are connected to the outer surface of the clamping plate.

[0008] As a further embodiment of this utility model: each of the two rolling components includes two second bearings, both sets of the second bearings are embedded in the inner wall of the housing, and the inner rings of both sets of the second bearings are connected to a rotating rod.

[0009] As a further improvement of this utility model: both outer surfaces of the two rotating rods are connected to anti-slip sleeves, and both anti-slip sleeves are made of rubber.

[0010] As a further improvement of this utility model: the bottom surfaces of the two clamping frames and the upper surfaces of the two support platforms are all connected to elastic pads, and both elastic pads are made of rubber.

[0022] According to one embodiment of the present invention, in conjunction with the appendix Figures 1-4 As shown.

[0023] A fastener for plastic packaging straps includes a housing 1. The housing 1 has symmetrical clamping plates 10 inside. First bearings 9 are embedded on opposite sides of the clamping plates 10. Threaded rods 8 are connected to the inner rings of both first bearings 9. Several insert rods 11 are connected to the left side of one clamping plate 10, and several insertion holes 12 are opened on the right side of the other clamping plate 10. The housing 1 has symmetrical rolling components 13 inside. Symmetrical positioning frames 6 are connected to the outer surface of the housing 1. Clamping frames 7 are slidably connected inside both sets of positioning frames 6. Symmetrical support platforms 14 are connected to the upper surface of the housing 1. Both support platforms 14 are located within the clamping... Below the frame 7, both positioning frames 6 are equipped with positioning components 5. Through the threaded connection between the threaded rod 8 and the outer shell 1, the rotating threaded rod 8 can drive the clamping plates 10 to move closer or separate from each other through the first bearing 9. Through the cooperation of the insertion rod 11 and the insertion hole 12, the packaging strap can be fixed. This allows the packaging strap and fasteners to be reused without cutting them during disassembly, reducing resource waste and packaging costs. Through the cooperation of the clamping frame 7 and the support platform 14, the packaging strap can be initially fixed, which is convenient for subsequent reinforcement work. The positioning frame 6 can limit the position of the clamping frame 7.

[0024] In this embodiment, the ends of the two threaded rods 8 that are far apart from each other both penetrate through the outer shell 1 and extend to the outside of the outer shell 1. The ends of the two threaded rods 8 that are far apart from each other are connected to an adjustment handle 2. By providing the adjustment handle 2, it is convenient for the staff to rotate the threaded rods 8, thereby facilitating the subsequent reinforcement work and improving the convenience of this device.

[0025] In this embodiment, the outer surface of the outer shell 1 is provided with symmetrical limiting grooves 4, and symmetrical limiting blocks 3 are slidably connected inside the two limiting grooves 4. The sides of the two sets of limiting blocks 3 that are close to each other are connected to the outer surface of the clamping plate 10. By the limiting blocks 3 sliding inside the limiting grooves 4 with the clamping plate 10, the clamping plate 10 can be limited, preventing the clamping plate 10 from shifting, providing guidance for the clamping plate 10, and improving the stability of the clamping plate 10 during operation.

[0026] In this embodiment, each of the two rolling components 13 includes two second bearings 131. Both sets of second bearings 131 are embedded in the inner wall of the outer shell 1. The inner rings of both sets of second bearings 131 are connected to rotating rods 132. The outer surfaces of the two rotating rods 132 are connected to anti-slip sleeves 17. Both anti-slip sleeves 17 are made of rubber. When the packaging tape passes through the inlet 18 and outlet 16 of the outer shell 1, the smoothness of the packaging tape movement is improved.

[0027] In this embodiment, the bottom surfaces of the two clamping frames 7 and the upper surfaces of the two support platforms 14 are connected to elastic pads 15. Both elastic pads 15 are made of rubber. When the clamping frames 7 and the support platforms 14 clamp the packaging tape, they can provide a certain elastic pressure to further enhance the fixing effect and prevent the packaging tape from loosening.

[0028] In this embodiment, both sets of positioning components 5 include bolts 501. The outer surfaces of both sets of bolts 501 are connected to the internal threads of the positioning frame 6. One end of each set of bolts 501 is connected to a screw block 502. By screwing the screw block 502, the bolts 501 are threadedly connected to the positioning frame 6, thereby fixing the position of the clamping frame 7 and achieving precise positioning of the packaging tape. The operation is simple and convenient, and the packaging efficiency is improved.

[0029] In this embodiment, the bottom surface of the outer shell 1 is provided with an inlet 18 and the upper surface of the outer shell 1 is provided with an outlet 16. The cooperation between the inlet 18 and the outlet 16 makes it easy for the packaging bag to pass through the outer shell 1, which facilitates the subsequent fixing work.

[0030] Working principle: During use, the plastic packaging tape is first inserted through the inlet 18 on the bottom surface of the outer casing 1, passes between the rotating rods 132 of the two sets of rolling components 13, and exits through the outlet 16 on the upper surface of the outer casing 1. Then, the two ends of the plastic packaging tape are placed on the two support platforms 14 respectively. Next, the clamping frame 7 is pressed down, causing it to slide inside the positioning frame 6 and initially clamp the plastic packaging tape. Then, the screw block 502 is rotated to rotate the bolt 501. The rotating bolt 501 presses against the clamping frame 7 for positioning. Finally, the threaded rod 8 is rotated, and the thread... The rod 8 drives the clamping plates 10 to move closer together via the first bearing 9, so that the insertion rod 11 passes through the plastic packaging tape and is inserted into the insertion hole 12 to ensure a firm fixation. When the packaging tape needs to be removed, the threaded rod 8 is rotated in the opposite direction, so that the threaded rod 8 drives the clamping plates 10 to move away from each other. The insertion rod 11 is pulled out of the insertion hole 12, and the two clamping plates 10 separate, so that the packaging tape loses the clamping force of the clamping plates 10. Then, the bolt 501 is rotated in the opposite direction to contact the positioning of the clamping frame 7. The clamping frame 7 is slid upward, and the packaging tape can be easily removed, realizing the disassembly and reuse of the fastener.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
