[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] like Figure 1 As shown, in one embodiment of this utility model, a cable tie guide assembly 100 for a cable tie machine is installed inside the cable tie machine for accurately guiding the cable ties. The cable tie guide assembly 100 includes a base plate 10, a drive wheel 20, and a guide block 30. The base plate 10 has a transmission surface 11 for cable tie transmission; the drive wheel 20 is mounted on the base plate 10 and drives the cable tie to move on the transmission surface 11; the guide block 30 is fixed to the base plate 10, positioned above the transmission surface 11, and located downstream of the drive wheel 20 along the transmission direction of the cable tie. The gap between the guide block 30 and the drive wheel 20 should be small enough to prevent them from contacting each other, but not large enough to allow the cable tie to slip out of the gap. In other words, the guide block 30 has a guiding function, guiding the cable tie to move on the transmission surface 11 and preventing the cable tie from being driven out of the transmission surface 11 by the drive wheel 20 and then moving around inside the cable tie machine.

[0022] To improve transport stability, the guide block 30 is fixed to the base plate 10 by at least two bolts 40 to prevent rotation due to unstable fixing. This prevents one end of the guide block 30 from moving away from the drive wheel 20, thus increasing the gap between the guide block 30 and the drive wheel 20. When this gap increases to a certain extent, the cable tie is still driven upwards by the drive wheel 20 and slips out through the gap. For example, in... Figure 1 In the embodiment shown, the guide block 30 is a long strip structure and is fixed to the base plate 10 by two bolts 40 at both ends.

[0023] Preferably, the strapping machine's cable tie guide assembly 100 further includes a limiting block 50 fixed on the base plate 10, which abuts against the guide block 30 to determine the installation position of the guide block 30. When the strapping machine is disassembled and reassembled after maintenance, the guide block 30 can be abutted against the limiting block 50, making assembly more convenient and easier for operators to handle.

[0024] Specifically, the limiting block 50 includes a first blocking portion 51 disposed on one side of the guide block 30 along the transmission direction of the cable tie and abutting against the guide block 30. When assembling the guide block 30, having one end abut against the first blocking portion 51 signifies that it is already in the installation position along the transmission direction of the cable tie, thus enabling rapid installation and adjustment of the guide block 30. Furthermore, the first blocking portion 51, located at the end of the guide block 30 and abutting against it, further enhances the stability of the guide block 30, ensuring stable operation of the cable tie.

[0025] Furthermore, the limiting block 50 also includes a second blocking part 52 disposed above the guide block 30 and abutting against the guide block 30. When assembling the guide block 30, when the guide block 30 abuts against the first blocking part 51 and the second blocking part 52 at the same time, it means that it is in the installation position in both the transmission direction of the cable tie and the transmission direction perpendicular to the cable tie, and the bolt 40 can be screwed in and tightened.

[0026] In one embodiment, in addition to the positioning function provided by the first blocking part 51 and the second blocking part 52, meshing teeth (not shown) are provided at the abutment of the guide block 30 and the limiting block 50, which makes it easier to install the guide block 30 and makes the guide block 30 more stable after installation.

[0027] In one embodiment, the cable tie guide assembly 100 of the cable tie machine further includes a pressure plate 60 fixed on the base plate 10, one end of which is close to the drive wheel 20. The pressure plate 60 is not in close contact with the transmission surface 11, and a gap is formed between the two, within which the cable tie is transmitted. Furthermore, the pressure plate 60 covers the transmission surface 11 downstream of the drive wheel 20, ensuring that the cable tie can be transmitted stably and smoothly to the rear end.

[0028] Preferably, the end of the pressure plate 60 near the drive wheel 20 is pivotally connected to the base plate 10, while the other end is connected to the base plate 10 via a spring (not shown). The two ends of the spring are connected to the base plate 10 and the pressure plate 60 respectively, so that the pressure plate 60 can rotate around the pivot end near the drive wheel 20 as the center. When it is necessary to coordinate with the operation of other components at the rear end, it can move by the spring traction, which is more flexible.

[0029] Furthermore, a limiting post 12 is provided on the substrate 10. The limiting post 12 is located downstream of the limiting block 50 along the transmission direction of the cable tie and above the pressure plate 60. The limiting post 12 restricts the range of motion of the pressure plate 60 and limits the upper limit of the movement of the pressure plate 60.

[0030] Preferably, the position of the limiting post 12 is set to abut against the first blocking part 51. This setting not only restricts the range of motion of the pressure plate 60, but also makes it easier to install the limiting block 50, and is more conducive to the disassembly and maintenance of the equipment.

[0031] In one embodiment, there is a notch (not shown) between the pressure plate 60 and the drive wheel 20, and the guide block 30 covers the notch from above. This arrangement allows the drive wheel 20 to contact and drive the cable tie at the notch location. Furthermore, in cases where the cable tie still detaches from the transmission surface 11 and moves inside the device, the limiting block 50 and the guide block 30 can be removed, and the cable tie can be guided back between the pressure plate 60 and the transmission surface 11 through the notch without having to completely disassemble the pressure plate 60, thus offering high flexibility and ease of use.

[0032] This embodiment also provides an improved desktop strapping machine (not shown), including a housing, a feeding shaft, a strapping assembly, a drive assembly, and the aforementioned strapping machine strapping guide assembly 100. The housing has an internal installation space, and a strapping inlet communicating with the internal installation space is provided on the side wall of the housing. An arched frame is provided on the top surface of the housing, and an annular channel for strapping to pass through is provided on the arched frame and on the top surface below the arched frame. The feeding shaft is fixed to the outer wall of the housing for holding the strapping roll. The strapping machine strapping guide assembly 100 is disposed inside the housing, with one end of the transmission surface 11 extending to the strapping inlet and the other end extending to one end of the channel at the arched frame. The strapping assembly is installed in the installation space for winding and fixing the strapping in the channel at the arched frame to the object to be strapped. The drive assembly is also installed in the installation space for driving the drive wheel 20 and the strapping assembly. The cable ties enter the cable ties machine through the cable tie inlet, and after passing through the cable tie guide assembly 100 and the annular channel within the arched frame, they flow back into the installation space. The object to be bundled is placed under the arched frame, and the bundling assembly tightens the cable ties onto the object. Finally, the cable ties are secured and cut. Afterward, the cable ties fill the annular channel within the arched frame and await the next bundling operation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
