[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Because the existing cutter head 37 is generally directly disassembled and assembled at the capping mechanism (capping station or capping head) inside the capping machine, and in order to adapt to different models of bottles, an arc-shaped mounting hole is set at the installation location. By adjusting the installation position of the cutter head 37 on the arc-shaped mounting hole, the distance between the cutter head 37 and the capping head can be matched. However, it is very difficult to accurately determine the installation position of the cutter head 37. It requires continuous debugging, which takes a long time, generally half a day, and sometimes a whole day, wasting a lot of time.

[0021] Therefore, this utility model embodiment provides a quick-change crimping cutter head assembly, which is a separate crimping module, and the position of the internal cutter head 37 can be adjusted by itself. So, before replacing the cutter head 37, the position of the cutter head 37 in the crimping module can be adjusted first, and then the replacement can be done directly when needed. This realizes the quick replacement of the cutter head assembly, saving debugging time and a lot of time. For the manufacturer, the time that would have been wasted on replacing and debugging the cutter head 37 is turned into production time, which is beneficial to the manufacturer.

[0022] Specifically, such as Figures 1-7As shown, the cutter head assembly includes a mounting bracket 1, a rotating bracket 2, and a cutter head sub-assembly 3. The mounting bracket 1 can be connected to an external connecting bracket 6, allowing the entire cutter head assembly to be mounted on the capping head. It should be noted that the connecting bracket 6 is generally fixed to the fixing bracket of the capping assembly, so after installation, the position of the mounting bracket 1 relative to the capping end of the capping assembly remains unchanged. The cutter head sub-assembly 3 is mounted on the rotating bracket 2 and can move together with the rotating bracket 2. The outer wall of the rotating bracket 2 is provided with a rotating end, which is rotatably mounted on the mounting bracket 1. Therefore, the cutter head sub-assembly 3 and the rotating frame 2 can rotate together with the rotating end relative to the mounting frame 1 to adjust the relative position between the cutter head 37 and the mounting frame 1, thereby adjusting the position of the cutter head 37. Correspondingly, a positioning element 4 is provided on the mounting frame 1. The positioning element 4 can fix the position of the rotating end after rotation. That is, the rotating end can first be rotated relative to the mounting frame 1. When it is rotated to a certain angle and adjusted to the required position, the rotating end is fixed by the positioning element 4 to fix the entire rotating frame 2 and the cutter head sub-assembly 3, so that the position of the cutter head 37 and the mounting frame 1 no longer changes.

[0023] In summary, since the position of the mounting bracket 1 relative to the pressure end of the pressure cap assembly remains unchanged after installation, once the relative position between the cutter head 37 in the cutter head assembly and the mounting bracket 1 changes, the relative position between the cutter head 37 and the pressure end of the pressure cap assembly will also change, and the distance between them will be adjusted. Therefore, the cutter head assembly in this embodiment is composed of the mounting bracket 1, the rotating bracket 2, the cutter head sub-assembly 3, and the positioning component 4, forming a modular configuration. When replacing the cutter head 37, it is replaced as a whole module. Before replacement, the cutter head 37 in the cutter head sub-assembly 3 within the module has already been adjusted to the required position, allowing for direct installation and saving downtime for debugging, which is beneficial for production users.

[0024] It is important to know that there can be multiple cutter head assemblies. Each cutter head assembly contains a cutter head 37 in a different position within its sub-assembly 3 to accommodate different bottle sizes. When a cutter needs to be changed, the corresponding cutter head assembly can be taken out and installed. For the producer, no adjustments are required; they can simply take the appropriate one.

[0025] Specifically, such as Figure 3-4As shown, a rotating groove 11 is provided in the middle of the outer wall of the mounting frame 1. A pin 13 is installed vertically on the mounting frame 1, and the pin 13 passes through the rotating groove 11 vertically. Correspondingly, a rotating end 21 is provided on the outer wall of the rotating frame 2. The end of the rotating end 21 is located in the rotating groove 11 and is rotatably mounted on the pin 13. Correspondingly, in order for the rotating frame 2 to rotate to a certain position and then stop and fix its position, a positioning element 4 is required. Specifically, in this embodiment, the positioning element 4 includes a positioning element 4 and a second positioning element 42, both of which are threaded to the outer wall of the mounting frame 1. The lower part of the mounting frame 1 is provided with a limiting groove 12, and the outer wall of the rotating frame 2 is provided with a limiting end 22, the end of which is located in the limiting groove 12. The rotating end 21 rotates within the limiting groove 12 as the rotating end 21 rotates. The limiting end 22 is configured with a first abutting surface 221 and a second abutting surface 222 at a certain angle. After the rotating frame 2 rotates to a fixed angle, the first positioning member 41 abuts against the first abutting surface 221 and the second positioning member 42 abuts against the second abutting surface 222, thereby limiting the rotation direction of the limiting end 22 and fixing it. This further limits the rotation direction of the entire rotating frame 2 and fixes its position. Of course, when it is necessary to adjust the position of the rotating frame 2 relative to the mounting frame 1 again, it is only necessary to rotate the first positioning member 41 and the second positioning member 42 in the opposite direction so that the first positioning member 41 and the second positioning member 42 are respectively away from the first abutting surface 221 and the second abutting surface 222.

[0026] Specifically, the rotating frame 2 is provided with a connection hole 23 in the vertical direction. The cutter head sub-assembly 3 includes a mounting rod assembly and a cutter head 37. The cutter head 37 is detachably installed on the lower part of the mounting rod assembly and is located below the rotating frame 2. The upper part of the mounting rod assembly is detachably connected to the connection hole 23, so the whole assembly can be detachably connected, which facilitates the replacement of the cutter head 37.

[0027] Specifically, such as Figure 5-6As shown, the mounting rod assembly includes a sleeve 31, a central rod 32, a first fastener 33, and a limiting part. The sleeve 31 is detachably connected to the connecting hole 23, and the two can be connected by threads for easy disassembly. The central rod 32 has a limiting protrusion 321 in the middle to separate the cutter head 37 and the sleeve 31. The upper end of the central rod 32 passes through the sleeve 31 and is located above it. The limiting part is detachably located at the upper end of the central rod 32, and the lower side wall of the limiting part abuts against the upper part of the sleeve 31, thereby fixing the position of the central rod 32 and preventing it from falling off. The central rod 32 can only be disassembled by removing the limiting part. The lower end of the central rod 32 passes through the cutter head 37 and is located below it. The first fastener 33 is fastened to the lower end of the central rod 32, so that the cutter head 37 can be rotated between the first fastener 33 and the limiting protrusion 321, thereby completing the fixation of the entire cutter head 37 and making the cutter head 37 detachable. Specifically, the first fastener 33 can be a bolt, with a washer between the bolt head and the cutter head 37; and the cutter head 37 has a bearing inside, so that during installation, the inner ring of the bearing is fixed to the limiting protrusion 321 and the first fastener 33, allowing the cutter head 37 and the internal center rod 32 to rotate relative to each other.

[0028] Specifically, in this embodiment, the limiting part includes an adjusting member 34, a nut 35, and an elastic member 36. The adjusting member 34 has an inner cavity and an open lower end. The outer wall of the upper end of the sleeve 31 is threadedly connected to the inner wall of the lower part of the adjusting member 34. The upper end of the central rod 32 extends into the adjusting member 34, and the nut 35 is threadedly connected to the top of the central rod 32. The elastic member 36 is correspondingly sleeved on the upper end of the central rod 32 and is located between the upper wall of the sleeve 31 and the lower wall of the nut 35. Furthermore, the inner cavity wall of the adjusting member 34 abuts against the nut 35, so by rotating the adjusting member 34, the limiting member moves relative to the sleeve 31. With the cooperation of the nut 35 and the elastic member 36, the central rod 32 moves vertically, thereby adjusting the height of the cutter head 37 and achieving fine adjustment of the cutter head 37. It should be noted that after all components are installed, the upper side wall of the limiting protrusion 321 abuts against the lower side wall of the sleeve 31, at which point the cutter head 37 is at its highest position. If adjustment is needed, simply rotate the adjusting member 34 forward. The adjusting member 34 will compress the nut 35 and the central rod 32, causing the central rod 32 to descend, thus lowering the cutter head 37. Meanwhile, the nut 35 compresses the elastic member 36, which supports the nut 35 and is also compressed. Therefore, if the adjusting member 34 needs to be rotated in the opposite direction, the elastic member 36 will cause the cutter head 37 to rise, achieving the adjustment of the cutter head 37's height. It should be noted that the elastic element 36 also pre-tightens and buffers the center rod 32, and also pre-tightens and buffers the cutter head 37.

[0029] Preferably, the outer wall of the upper end of the sleeve 31 is recessed to form a boss 311. The side wall of the boss 311 and the upper side wall of the connecting hole 23 form an annular groove for placing the adjusting member 34, so that the bottom of the adjusting member 34 is hidden, which improves the aesthetics. In addition, it increases the threaded connection length between the lower part of the limiting member and the upper end of the sleeve 31 to a certain extent, ensuring the stable connection between the two.

[0030] Preferably, the lower outer wall of the sleeve 31 is provided with an annular protrusion 312, and the lower end of the connecting hole 23 is provided with a coaxial countersunk hole. The annular protrusion 312 abuts against the bottom of the countersunk hole, thereby playing a positioning and connection role, so that the sleeve 31 and the connecting hole 23 are accurately positioned after connection, without requiring the manufacturer to... Preferably, the outer wall of the rotating frame 2 is provided with a fixing hole that communicates with the connecting hole 23. A second fastener 5 that abuts against the sleeve 31 is provided on the fixing hole. The sleeve 31 can be further tightened by the second positioning member 42 so that the sleeve 31 will not move in the axial and radial directions.

[0031] This utility model embodiment also provides a capping knife mounting assembly, such as Figure 7 As shown, the assembly specifically includes a connecting frame 6 and the aforementioned cutter head assembly. The mounting bracket 1 within the cutter head assembly has a limiting rod 14. The connecting frame 6 has a first mounting hole and a second mounting hole that are connected, allowing the limiting rod 14 to be inserted into the first mounting hole. Then, an existing spring pin 7 is inserted into the second mounting hole. The spring pin 7 works in conjunction with the limiting rod 14 to fix or remove the limiting rod 14. That is, when replacing, simply press the spring pin 7 to release the spring pin 7 from locking the limiting rod 14, and then the limiting rod 14 can be pulled out from the first mounting hole, thus completing the disassembly of the cutter head assembly and the connecting frame 6. When installing, simply insert the limiting rod 14 into the first mounting hole and then press the spring pin 7 to lock the two together, thus completing the installation of the cutter head assembly on the connecting frame 6.
