Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1-2As shown, a strapping machine strapping box feeding device includes: a strapping box fixing plate 1, a strapping servo motor 2, a strapping drive wheel 3, and a strapping auxiliary wheel 4. The strapping servo motor 2 has a higher strapping speed than the strapping servo motor at the head of the strapping machine. The strapping box fixing plate 1 is located inside the strapping machine housing and is used to fix the strapping feeding device. The strapping servo motor 2 is located on one side of the strapping box fixing plate 1. The strapping drive wheel 3 is located on the other side of the strapping box fixing plate 1 and is connected to the drive end of the strapping servo motor 2. The strapping auxiliary wheel 4 is located at the upper end of the strapping drive wheel 3, with a certain gap between them. The strapping tape passes through the gap between the strapping drive wheel 3 and the strapping auxiliary wheel 4.

[0040] Powered by the feed servo motor 2, the strapping tape is fed by the friction of the feed drive wheel 3 and the feed auxiliary wheel 4. The feeding speed of the feed servo motor 2 is higher than that of the feeding servo motor at the head of the strapping machine, so a portion of the strapping tape will enter the storage box. By adjusting the PLC parameters, the feed and feeding amounts of the feed servo motor 2 and the feeding servo motor at the head of the strapping machine can be analyzed and controlled, thereby maintaining a certain amount of strapping tape in the storage box.

[0041] As a further embodiment, the belt feed wheel 4 is equipped with a cam mechanism for adjusting the belt thickness, such as... Figures 2-3 As shown, specifically, the cam mechanism includes: a connecting shaft 5, a circular block 6, and an adjusting shaft 7, wherein: the connecting shaft 5 is rotatably connected to the center of the feed roller 4; the circular block 6 is located at one end of the connecting shaft 5 near the belt compartment fixing plate 1, and the connecting shaft 5 is connected to one side of the circular block 6; the adjusting shaft 7 is located on the other side of the circular block 6, and the adjusting shaft 7 is not axially aligned with the connecting shaft 5; the circular block 6 is located in the circular chamber 8 on the side of the feed roller 4 near the belt compartment fixing plate 1, and the radius of the circular chamber 8 is larger than the radius of the circular block 6; the adjusting shaft 7 is rotatably connected to the motor base 9, the motor base 9 is located on one side of the belt compartment fixing plate 1, and the feed servo motor 2 is fixed on the motor base 9.

[0042] In this embodiment, the gap between the feed roller 4 and the feed drive roller 3 is adjusted by rotating the adjusting shaft 7, thus making it suitable for packing straps of different thicknesses. By setting the adjusting shaft 7 and the connecting shaft 5 to have different axes, the circular block 6 realizes the function of a cam. When rotating the adjusting shaft 7, the height of the connecting shaft 5 is adjusted by the circular block 6, thereby adjusting the gap between the feed roller 4 and the feed drive roller 3.

[0043] like Figure 1As shown, to ensure smooth conveying of the strapping tape and allow excess strapping tape to fall into the storage bin below, the strapping machine's strapping tape feeding device further includes: a first support roller 10 and a second support roller 11. The first support roller 10 is mounted on the tape bin fixing plate 1 along the tape feeding direction, and the second support roller 11 is located on the side of the first support roller 10 away from the feeding drive wheel 3. The first support roller 10 and the second support roller 11 support the strapping tape, ensuring its smooth passage. Additionally, a first feeding guide 12 for the strapping tape to pass through is provided above the second support roller 11, and a feeding guide groove 13 is provided between the first support roller 10 and the second support roller 11. The feeding guide groove 13 has a U-shaped structure with an opening at the bottom, allowing excess strapping tape to fall smoothly from the feeding guide groove 13 into the storage bin.

[0044] As a further embodiment, a strapping bin baffle plate 14 is provided on the opposite side of the strapping bin fixing plate 1. The strapping bin fixing plate 1, the strapping bin baffle plate 14, and the inner side of the bottom wall of the strapping machine form a strapping bin.

Excess strapping falls into the strapping bin formed by the strapping bin fixing plate 1, the strapping bin baffle plate 14, and the inner side of the bottom wall of the strapping machine, making the inside of the strapping machine cleaner.

[0045] The strapping machine's strapping box feeding device of this utility model has a simple structure. It does not require a balance bar or spring to control the amount of strapping tape remaining in the strapping box. Instead, it relies on adjusting the feeding speed of the feeding servo motor 2 and the feeding servo motor at the head of the strapping machine. By adjusting the PLC parameters, the feeding and feeding amounts of the feeding servo motor 2 and the feeding servo motor at the head of the strapping machine are analyzed and controlled, thereby maintaining a certain amount of strapping tape remaining in the strapping box.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
