[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to the appendix Figure 1 To be continued Figure 2This embodiment provides a novel drum core mating structure, including a connecting gear head 1, a drum core drive head 2 located at the end of the drum core, a coupling mechanism 3 located between the connecting gear head 1 and the drum core drive head 2, and a locking mechanism 4. The connecting gear head 1 is detachably connected to the drum core drive head 2. The coupling mechanism 3 includes a first insertion platform 31, a first insertion groove 32, a mating connecting post 33, and a mating connecting hole 34. The locking mechanism 4 includes a transmission boss 41 located between the first insertion platform 31 and the first insertion groove 32, and a mating groove wall 42. The transmission boss 41 and the mating groove wall 42 are polygonally mated. When the connecting gear head 1 is connected to the drum core drive head 2, the mating connecting post 33 is inserted into the mating connecting hole 34 to restrict the radial movement freedom of the connecting gear head 1 relative to the drum core drive head 2. The circumference of the transmission boss 41 abuts against the mating groove wall 42 to restrict the axial rotation freedom of the connecting gear head 1 relative to the drum core drive head 2. The novel drum core mating structure of this embodiment adds a connecting gear head 1 and a drum core drive head 2 at the end of the drum core. A coupling mechanism 3 and a locking mechanism 4 are then provided between the connecting gear head 1 and the drum core drive head 2. The coupling mechanism includes a first insertion platform 31, a first insertion groove 32, a mating connecting post 33, and a mating connecting hole 34. The locking mechanism 4 includes a transmission boss 41 and a mating groove wall 42. Firstly, the quick insertion and removal of the mating connecting post 33 and the mating connecting hole 34 enables the rapid assembly and disassembly of the connecting gear head 1 and the drum core drive head 2, and achieves [further details needed] in the connected state. The relative radial movement of the connecting gear head 1 and the drum core drive head 2 is restricted. At the same time, after the connecting gear head 1 and the drum core drive head 2 are connected, the transmission boss 41 will make a polygonal mating connection with the mating groove wall 42, which restricts the relative axial rotation of the connecting gear head 1 and the drum core drive head 2, thereby realizing the transmission connection between the connecting gear head 1 and the drum core drive head 2. If a drum with this drum core mating structure needs to be replaced with a different model of drum core, the drum core can be quickly replaced by simply plugging and unplugging it, making the drum core replacement more efficient and saving consumable costs.

[0021] The connecting post 33 and the connecting hole 34 are detachable with an interference fit, which makes the transmission connection between the connecting gear head 1 and the drum core drive head 2 more stable.

[0022] The sidewall of the transmission boss 41 is twisted around the axial direction, so that the connecting gear head 1 and the drum core drive head 2 tend to move closer to each other during transmission, so that the connecting gear head 1 and the drum core drive head 2 remain tightly connected when rotating.

[0023] The cross-section of the transmission boss 41 is triangular, and it is arranged in a "Y" shape around the groove wall 42 to form a "Y" shaped mating area. The triangular transmission mating arrangement saves costs.

[0024] Preferably, the first insertion platform 31 is disposed on the drum core drive head 2, the first insertion groove 32 is disposed on the connecting gear head 1, the transmission boss 41 is disposed at one end of the first insertion platform 31 near the first insertion groove 32, and the mating groove wall 42 is disposed on the inner wall of the first insertion groove 32.

[0025] Preferably, the connecting hole 34 is provided on the side of the transmission boss 41 near the first insertion groove 32, and the connecting post 33 protrudes into the first insertion groove 32.

[0026] Preferably, the connecting hole 34 and the first insertion platform 31 are coaxially arranged.

[0027] The end of the mating connecting post 33 is provided with a first calibration chamfer 331 arranged around it, and the opening of the mating connecting hole 34 is provided with a second calibration chamfer 341 arranged around it, corresponding to the first calibration chamfer 331. The mating of the first calibration chamfer 331 and the second calibration chamfer 341 allows for an allowable alignment error when the mating connecting post 33 and the mating connecting hole 34 are mated, and corrects the alignment position of the two when they are connected, so that the mating connecting post 33 can be accurately inserted into the mating connecting hole 34.

[0028] The coupling mechanism 3 also includes a second insertion platform 35 and a second insertion slot 36 arranged in a ring shape. The diameters of the second insertion platform 35 and the second insertion slot 36 are both larger than those of the first insertion platform 31. The mating connection between the second insertion platform 35 and the second insertion slot 36 plays an auxiliary role in restricting the radial degree of freedom of movement between the connecting gear head 1 and the drum core drive head 2.

[0029] Preferably, the second insertion platform 35 is disposed around the periphery of the first insertion slot 32, and the second insertion slot 36 is disposed around the periphery of the first insertion platform 31.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
