[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] See also Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a direct-drive motor, including a motor housing 100, an output shaft 200, an inner stator 300 and an outer rotor 400; a mounting seat 110 for mounting the inner stator 300 is provided on the motor housing 100, and the output shaft 200 is rotatably inserted in the mounting seat 110, one end of the output shaft 200 can pass through the mounting seat 110 to be connected to the pulper, and the other end of the output shaft 200 is connected to the outer rotor 400.

[0036] Specifically, when in use, the outer rotor 400 can drive the output shaft 200 to rotate, so that the output shaft 200 can output power, wherein one end of the output shaft 200 can pass through the mounting seat 110 to be connected to the pulper, and the other end of the output shaft 200 is connected to the outer rotor 400. Through such a setting, the direct-drive motor can be directly connected to the pulper without the need for other transmission structures, thereby reducing the loss of power transmission, improving the efficiency of the system, and reducing production costs. Moreover, such an installation method can save the installation space of the motor.

[0037] Among them, the end of the mounting seat 110 protruding from the motor housing 100 is provided with a connecting flange 111 that can be connected to the pulper. Through the setting of the connecting flange 111, the direct drive motor provided in this embodiment can be mounted on the outer wall of the pulper, and the output shaft 200 can be directly connected to the impeller of the pulper.

[0038] It should be emphasized that one end of the output shaft 200 passes through the inner stator 300, and the other end is connected to the outer rotor 400. A support bearing 112 for carrying the output shaft 200 is provided in the mounting seat 110, so that the body of the output shaft 200 is located on the support bearing 112 of the mounting seat 110. Through such a setting, the length of the output shaft 200 can be hidden inside the motor housing, thereby reducing the length of the output shaft 200 extending out of the motor housing 100, making full use of the space occupied by the inner stator 300 and the outer rotor 400 themselves, thereby greatly reducing the installation space required for the direct-drive motor as a whole.

[0039] In addition, it is also necessary to point out that the shaft body of the output shaft 200 is located inside the motor housing 100. Even if the output shaft 200 is shorter than the length of the motor housing 100, the output shaft 200 is still long enough to maintain its strength and stability, thereby solving the problem of stability of the single drive shaft and realizing the temperature operation of the single drive shaft pulping direct drive motor. Moreover, the output shaft 200 of the direct drive motor provided in this embodiment can balance the upward axial force of the pulper impeller and balance the axial force of the bearing.

[0040] A fourth reinforcing rib 530 is disposed between the motor housing 100 and the mounting seat 110 . The fourth reinforcing rib 530 is disposed to further improve the connection stability between the motor housing 100 and the mounting seat 110 .

[0041] See also Figure 1 , Figure 2 and Figure 3 As shown, in an optional solution of this embodiment, an adapter fixing plate 410 is provided on the outer rotor 400 , and the output shaft 200 is connected to the outer rotor 400 via the adapter fixing plate 410 .

[0042] A rotor mounting ring plate 420 for mounting the outer rotor 400 is disposed on the adapter fixing plate 410 , and the outer rotor 400 is disposed on the inner side of the rotor mounting ring plate 420 .

[0043] Wherein, a first reinforcing rib 430 is disposed on the outer side of the rotor mounting ring plate 420 .

[0044] Specifically, a first reinforcing rib 430 is provided on the outer side of the rotor mounting ring plate 420. Through such a configuration, the thickness and weight of the rotor mounting ring plate 420 can be reduced without affecting the structural strength of the rotor mounting ring plate 420. Moreover, when the rotor mounting ring plate 420 rotates, the first reinforcing rib 430 can circulate air, thereby assisting in providing a certain heat dissipation capacity.

[0045] See also Figure 1 , Figure 2 and Figure 3As shown, in an optional solution of this embodiment, a second reinforcing rib 510 is provided between the adapter fixing plate 410 and the rotor mounting ring plate 420 .

[0046] Specifically, a second reinforcing rib 510 is provided between the adapter fixing plate 410 and the rotor mounting ring plate 420. The second reinforcing rib 510 can ensure that the outer rotor 400 can stably drive the output shaft 200. The thickness and weight of the adapter fixing plate 410 can be reduced.

[0047] See also Figure 1 , Figure 2 and Figure 3 As shown, in an optional solution of this embodiment, the outer ring of the mounting seat 110 is provided with a support ring frame 120 for mounting the inner stator 300 , and a third reinforcing rib 520 is provided between the support ring frame 120 and the mounting seat 110 .

[0048] Specifically, the outer ring of the mounting seat 110 is provided with a support ring frame 120, the inner stator 300 is installed on the support ring frame 120, and a third reinforcing rib 520 is provided between the support ring frame 120 and the mounting seat 110 to improve the stability between the support ring frame 120 and the mounting seat 110.

[0049] See also Figure 1 , Figure 2 and Figure 3 As shown, in an optional solution of this embodiment, a vent hole 121 is provided on the support ring frame 120 .

[0050] Specifically, by providing the vent holes 121 on the support ring frame, not only the weight of the support ring frame 120 can be reduced, but also a heat dissipation channel can be formed inside to improve the heat dissipation capacity of the motor.

[0051] This embodiment provides a paper pulping machine, including a direct drive motor.

[0052] Specifically, the paper pulper provided in this embodiment has the advantages of the above-mentioned direct drive motor compared with the prior art, which will not be described in detail here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
