DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 、 Figure 2 and Figure 3As shown, a spiral shaft motor includes a driving mechanism 1, which includes a mounting seat 11 and a motor body 12. The motor body 12 is fixed in the mounting seat 11. A connecting member 2 is installed on the output shaft of the motor body 12. The connecting member 2 is fixedly engaged with the output shaft of the motor body 12. A rotating frame 3 is fixedly installed on the outer end of the connecting member 2. A positioning rod 4 is installed in the middle of the rotating frame 3. A spiral blade 5 is fixedly installed on the outer surface of the positioning rod 4.

[0028] By arranging the structure of the driving mechanism 1 so that it is easy to use, the motor body 12 is fixed in the mounting seat 11, so that it can be fixed to the external bracket through the mounting seat 11 during installation, so that the motor body 12 can be used stably. At the same time, by installing the connecting piece 2 at the output end of the motor body 12, it is easy to ensure that the rotating frame 3 can be stably connected to the output end of the motor body 12 through the connecting piece 2, and then the rotating frame 3 can be driven to rotate by the motor body 12. By fixing the positioning rod 4 in the rotating frame 3, it can be ensured that the spiral blade 5 can be stably fixed to the rotating frame 3 and the positioning rod 4, thereby driving the spiral blade 5 to rotate stably to transport raw materials.

[0029] A positioning ring 111 is provided on the outer surface of the mounting base 11. The positioning ring 111 is integrally formed with the mounting base 11, and a positioning groove 121 is provided on the output shaft of the motor body 12. The provision of the positioning ring 111 ensures that the mounting base 11 and the external bracket can be mutually engaged and positioned, thereby increasing the stability of the device installation. At the same time, the provision of the positioning groove 121 facilitates better engagement and fixation of the connector 2.

[0030] Reference Figure 3 and Figure 4 As shown, the connecting member 2 includes a sleeve 21 and a movable block 22. The sleeve 21 is sleeved on the output shaft of the motor body 12. The movable block 22 is slidably installed in the sleeve 21, and a connecting tension spring 23 is installed between the movable block 22 and the sleeve 21.

[0031] By configuring the structure of the connector 2, it is ensured that when in use, the connector can be sleeved on the output shaft of the motor body 12 through the sleeve 21 for connection. At the same time, the movable clamping block 22 is slidably installed on the sleeve 21. In this way, when the sleeve 21 is sleeved on the output shaft of the motor body 12, the movable clamping block 22 can be stably engaged in the positioning groove 121 under the action of the connecting tension spring 23, thereby ensuring a stable connection between the two.

[0032] The shaft sleeve 21 includes a sleeve portion 211 and a guide housing 212. The guide housing 212 is disposed on the outer surface of the sleeve portion 211 and is integrally formed with the sleeve portion 211. The structural configuration of the shaft sleeve 21 ensures that the sleeve portion 211 can be mounted on the output shaft of the motor body 12 during installation. By integrally forming the guide housing 212 on the outer surface of the sleeve portion 211, the movable clamping block 22 can be installed through the guide housing 212. Limiting slots 213 are defined on both sides of the guide housing 212, and an outer cover 214 is also mounted on the guide housing 212. An elastic clamping plate 215 is fixedly mounted on one side of the outer cover 214.

[0033] By providing limiting grooves 213 on both sides of the guide shell 212, it is ensured that the outer cover 214 can be installed after the sleeve 21 is sleeved on the output shaft. By fixing the outer cover 214 on the guide shell 212, the movable block 22 in the guide shell 212 can be limited, thereby ensuring that the output shaft can stably drive the connecting member 2 to rotate and prevent the movable block 22 from slipping out of the positioning groove 121.

[0034] Reference Figure 4 and Figure 5 As shown, the rotating frame 3 includes a main frame portion 31 and a connecting plate 32. The connecting plate 32 is installed between the main frame portions 31 and is fixedly connected to the main frame portions 31. The structural setting of the rotating frame 3 ensures that the connecting plate 32 can be fixedly installed in the main frame portion 31 during use, ensuring that the connecting plate 32 can assist in supporting the positioning rod 4, thereby increasing the stability of the spiral blade 5 on the positioning rod 4 during feeding. Auxiliary scrapers 311 are installed on both sides of the main frame portion 31, and the auxiliary scrapers 311 are fixedly connected to the main frame portion 31. By installing the auxiliary scrapers 311 on both sides of the main frame portion 31, the inner wall of the conveying pipe can be cleaned when the rotating frame 3 rotates to prevent the adhesion of raw materials.

[0035] In this embodiment, during actual installation, the driving mechanism 1 is first fixedly mounted on the external bracket through the mounting seat 11, and then the rotating frame 3 can be installed to ensure that the rotating frame 3 can be sleeved on the output shaft of the motor body 12 through the connecting piece 2 on the head. After the movable block 22 is engaged and fixed in the positioning groove 121, the outer cover 214 can be installed on the guide shell 212 to ensure that the movable block 22 is limited and fixed by the outer cover 214, and the outer cover 214 can be stably fixed on the guide shell 212 under the action of the elastic card plate 215 to achieve stable installation. In this way, the rotating frame 3, the positioning rod 4 and the spiral blade 5 can be driven to rotate synchronously through the motor body 12.

[0036] Since screw shaft motors are often used in work areas that require unidirectional rotation, but may also be subjected to reverse impact forces, in order to protect the screw shaft motor, in a preferred embodiment, the motor body 12 transmits torque to the output shaft through a unidirectional transmission member.

[0037] The one-way transmission member may be a one-way ratchet mechanism. In a preferred embodiment, the one-way transmission member is a one-way overrunning clutch, which has smoother transmission and minimizes the impact on the electrode body 12 when forced to reverse by a reverse force.

[0038] In a preferred embodiment, the motor body is a stepper motor. A stepper motor is a type of precision motor whose rotor consists of multiple magnetic poles. Rotation is achieved by controlling the direction and magnitude of the current. This type of motor offers advantages such as high precision, high reliability, low noise, and stable speed.

[0039] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
