[0020] Refer to the attached drawings. The strapping machine provided by the present invention includes a lower frame 100 and an upper fixed frame 200. The upper fixed frame 200 and the lower frame 100 are connected as a whole. An openable tape path is provided on the upper fixed frame, or an openable tape path is formed in cooperation with other components such as a movable frame. The tape path surrounds the strapping working position.

[0021] A frame cross beam 101 is provided in the lower frame 100. The strapping machine is further provided with an integral mounting seat 1. The integral mounting seat 1 is used as a detachable mounting structure. The integral mounting seat 1 is arranged on the frame cross beam 101, and the integral mounting seat 1 and the frame cross beam 101 are detachably connected through a threaded connection structure. The integral mounting seat 1 is provided with a first connection seat 11 for the movement mechanism frame 300 and a second connection seat 12 for the connection and installation structure of the tape feeding / reversing and tensioning mechanism. The movement mechanism frame 300 of the strapping machine and the first connection seat 11 are detachably connected through a threaded connection structure, and the connection and installation structure and the second connection seat 12 are detachably connected through a threaded connection structure.

[0022] The connection and installation structure is a unified installation and connection structure for the tape feeding / reversing and tensioning mechanism disassembly and assembly module, on which a wheel set 401 for tape feeding / reversing and a wheel set 402 for tape tensioning are provided. This connection and installation structure is not only detachably connected to the integral mounting seat 1 at the lower part, but also detachably connected to the movement mechanism frame 300 at one side, and detachably connected to the upper fixed frame 200 at the upper part.

[0023] The first connection seat 11 and the second connection seat 12 are arranged at different positions in the length direction of the integral mounting seat; the integral mounting seat is respectively provided with abutting and supporting parts 13, 14 that cooperate with the frame cross beam below the movement mechanism frame 300 and below the connection and installation structure.

[0024] The connection and installation structure includes a first part 21 connected to the movement mechanism frame 300 near one side thereof, a second part 22 connected to the second connection seat 12 near the lower part thereof, and a third part 23 connected to the upper fixed frame 200 near the upper part thereof. These connection parts can all be screw connection holes.

[0025] The connection and installation structure of the tape feeding / retracting and tensioning mechanism includes a mounting plate 3 and a mounting member 4. The mounting member is a metal block with a certain thickness. The mounting plate 3 is provided with a first part 21 and a third part 23. The motor in the tape feeding / retracting and tensioning mechanism is connected to the mounting member 4. The mounting member 4 is provided with a second part 22. The mounting plate 3 is connected to the mounting member 4. By providing the mounting plate 3 and the mounting member 4, it is convenient to connect the connection and installation structure to the movement frame 300, the second connection seat 12, and the upper fixing frame 200. This not only ensures the stable foundation of the connection and installation structure but also facilitates modular installation and disassembly, reducing the workload of disassembly, assembly, and debugging. At the same time, it can make the overall connection and installation structure stable, ensuring that the mounting plate 3 forms a unified reference for the tape feeding and rewinding of the movement.

[0026] A second part can also be provided on the mounting plate 3. The second part on the mounting plate 3 can be a part 24 that is separately connected to the second connection seat 12 of the mounting seat 1, or / and a part 25 that is connected to both the mounting member 4 and the second connection seat 12 of the mounting seat. The second part on the mounting plate 3 and the second part on the mounting member 4 can be aligned or misaligned. The mounting plate 3 and the mounting member 4 are connected through a threaded connection structure, and the reference numeral 405 in the attached drawing is its connection hole.

[0027] Furthermore, the mounting member 4 is located on the back of the mounting plate 3. A plurality of positioning pins 5 are provided on the mounting member 4, and positioning holes that are in clearance fit with the positioning pins 5 are provided on the mounting plate 3. The positioning pins 5 also pass through the stationary components in the tape feeding / retracting and tensioning mechanism mounted on the front of the mounting plate 3, such as the tensioning tape path component 403. The stationary component penetrated by the positioning pins 5 is provided with positioning holes 51 that are in clearance fit with the positioning pins 5. In this way, the mounting plate 3 can be used to receive the wear and high-speed cutting of the tape instead of the mounting member 4. It is suitable to install and position the positioning pins 5 on the mounting member 4. In this way, not only can the replacement of the mounting member 4 be avoided, but also the positioning of the positioning pins 5 can be used to avoid additional debugging work when replacing the mounting plate, reducing the workload of disassembly and replacement.

[0028] The lower end of the mounting plate 3 stops at the integral mounting seat 1, and its height reaches the position of the lower tape path of the upper fixing frame. It can directly serve as the side wall of the tape path of the tape feeding / retracting and tensioning mechanism. The tape feeding tape path component 404 and the tensioning tape path component 403 directly form a tape guiding groove with the mounting plate 3. The upper part of the mounting plate 3 also simultaneously serves as the side wall of the tape path before the packing tape turns back into the hot stamping, cutting, and sticking position 500. At the hot stamping, cutting, and sticking position 500, a packing tape hot stamping mechanism and a cutting mechanism are installed on the movement frame.

[0029] The side of the upper part of the mounting plate 3 that serves as the side wall of the tape path is chamfered 32 on the side away from the hot stamping, cutting, and sticking position 500 to avoid affecting the smooth turning of the head of the packing tape into the hot stamping, cutting, and sticking position 500 due to the error at the connection.

[0030] The tape feeding / discharging and tensioning mechanisms are respectively provided with a tape feeding / discharging drive motor and a tensioning drive motor 406. The tensioning drive motor 406 is connected to the mounting member 4, and the tape feeding / discharging drive motor is connected to the fixed structure under the frame cross beam.

[0031] The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the protection scope of the present invention.
