[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] The following is combined with Figures 1 to 4 The embodiments of this utility model are described below.

[0030] This application provides a strapping machine core, which includes a bracket 100, a guide belt mechanism 200, and a tightening mechanism 300;

[0031] The belt guide mechanism 200 is mounted on the bracket 100, and the top of the belt guide mechanism 200 is provided with a belt feeding channel 210;

[0032] The tightening mechanism 300 includes a drive unit 310 and a belt pressing assembly 320. The belt pressing assembly 320 is disposed above the belt feeding channel 210. The drive unit 310 is fixed on the bracket 100. The drive unit 310 is used to drive the belt pressing assembly 320 to move toward the belt feeding channel 210 so that the belt pressing assembly 320 presses or loosens the packing strap.

[0033] The existing assembly method, which uses multiple mechanical components such as cam 550 and elastic elements to connect and cooperate with each other, has a complex structure, many points of failure, and is difficult to maintain and debug.

[0034] Therefore, by providing a driving component 310 and a pressing assembly 320, the driving component 310 directly drives the pressing assembly 320 to move, thereby converting it into downward pressure from the pressing mechanism. This causes the pressing assembly 320 to tighten or loosen the strapping, effectively tightening the strap and ensuring the bundling effect. Compared to the traditional method of complex mechanical component assembly, the improved method simplifies the assembly structure, reduces potential failure points, and improves the stability of the equipment.

[0035] Specifically, the belt pressing assembly 320 includes a connecting shaft 321, a belt pressing wheel 322, and a transmission plate 323. The connecting shaft 321 is fixed on the bracket 100. The transmission plate 323 is rotatably connected to the connecting shaft 321 and is located on one side of the belt feeding channel 210. The belt pressing wheel 322 is fixed on the transmission plate 323 and is located above the belt feeding channel 210. The driving member 310 drives the transmission plate 323 to rotate around the connecting shaft 321, so as to drive the belt pressing wheel 322 to press against or move away from the surface of the belt feeding channel 210.

[0036] In this way, when the belt needs to be tightened, the drive unit 310 drives the transmission plate 323 to rotate around the connecting shaft 321. The transmission plate 323 drives the pressure roller 322 fixed on it to move, so that the pressure roller 322 presses against or moves away from the surface of the belt feeding channel 210. Thus, when the belt is actually fed, the pressure roller 322 can press against the belt on the surface of the belt feeding channel 210, increasing the friction between the belt and the pressure roller 322, thereby achieving the function of tightening the belt.

[0037] In some embodiments, the driving element 310 can be an electromagnet, and the transmission plate 323 is provided with a magnetically conductive layer. The magnetically conductive layer can use existing magnetically conductive materials, i.e., materials that can be attracted by a magnet. The electromagnet is disposed on one side of the magnetically conductive layer to achieve rotational control of the transmission plate 323 when energized. Optionally, the transmission plate 323 can also be made of iron sheet to cooperate with the electromagnet.

[0038] Specifically, when the electromagnet is energized, it generates magnetic force, attracting the transmission plate 323 with a magnetic conductive layer to rotate, which in turn drives the pressure roller 322 to press down to a certain position; when the electromagnet is de-energized, the magnetic force disappears, and the transmission plate 323 returns to its original position. The action is rapid and easy to control. Compared with traditional multiple connection mechanisms, the structure is simple, the assembly is convenient, and the production cost is reduced.

[0039] Understandably, an adjustment mechanism can be provided to flexibly adjust the strapping tension. This adjustment mechanism is electrically connected to an electromagnet. By adjusting the current input to the electromagnet, the magnitude of the magnetic force generated by the electromagnet is changed, thereby altering the pressure of the pressure roller 322 on the strap. This allows for adjustment of the strapping tension according to different strapping needs, improving the applicability of the strapping machine.

[0040] In some embodiments, the transmission plate 323 includes a rotating end 3231 near the connecting shaft 321 and a driving end 3232 away from the connecting shaft 321, with the driving end 3232 extending into the magnetic field range of the electromagnet. When the electromagnet generates magnetic force, it attracts the driving end 3232 of the transmission plate 323, causing the transmission plate 323 to rotate around the connecting shaft 321 with the rotating end 3231 as the axis, thereby driving the pressure roller 322 to move, so as to realize the action of tightening or loosening the belt.

[0041] In some embodiments, the belt feeding channel 210 has an inclined portion 211, and the pressure roller 322 is disposed above the inclined portion 211. By providing the inclined portion 211, the contact angle between the belt and the pressure roller 322 is changed, so that when the belt is pressed by the pressure roller 322 in an inclined state, greater friction is generated, thereby improving the belt tightening effect.

[0042] In some embodiments, the guide belt mechanism 200 further includes a feed roller 220, the feed belt channel 210 is provided with a guide belt opening 212, and the feed roller 220 is located below the guide belt opening 212 and is used to drive the packing strap to move. In actual use, a drive device is provided on one side of the frame, and the output end of the drive device is connected to the feed roller 220. The drive device drives the feed roller 220 to rotate, thereby driving the packing strap on the guide belt opening 212 to move. That is, the friction between the feed roller and the packing strap provides power for the movement of the packing strap, enabling it to move in the feed belt channel 210 and transport the strap to the designated position.

[0043] In some embodiments, the bracket 100 is further provided with a fusion mounting position 400, which is located on one side of the guide belt mechanism 200. The fusion mounting position 400 can be directly configured with a fusion mechanism, facilitating the direct mounting of fusion components on the mechanism. After installation, the belt is heated using a heating element installed on the fusion mounting position 400 to bring it to a molten state, and then solidified and connected by cooling or other methods to complete the binding process.

[0044] In some embodiments, the bracket 100 is also provided with a drive assembly 500 for driving other accessories on the strapping machine to move. By providing the drive assembly 500, it is easy to connect with other accessories on the strapping machine, thereby driving other components to move and improving the versatility of the mechanism.

[0045] Optionally, the drive assembly 500 includes a drive motor 510, a drive wheel 520, a transmission wheel 530, a transmission shaft 540, and multiple cams 550. The drive motor 510 is fixed on the bracket 100. The drive wheel 520 is connected to the output shaft of the drive motor 510. The transmission shaft 540 is connected to the drive wheel 520 via the transmission wheel 530. The multiple cams 550 are fixed on the transmission shaft 540 to drive other accessories to move. For example, the strapping machine is equipped with a cutting mechanism located above the drive assembly. The cutting mechanism is connected to the cams 550. In use, the drive motor 510 starts, driving the drive wheel 520 to rotate. The drive wheel 520 is connected to the transmission wheel 530 via a belt, thereby driving the transmission shaft 540 to rotate. The cams 550 on the transmission shaft 540 rotate accordingly. Since the cams 550 are connected to the cutting mechanism, they can drive the cutting mechanism to move up and down for cutting. It is understandable that the drive assembly 500 can also work with other accessories on the strapping machine for transmission, and there are no restrictions on this.
