[0040] In order to further understand the content, characteristics and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings. It should be noted that this embodiment is descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0041] This design mechanism is specifically used for the rotating shuttle box of a rotating sewing machine and is not applicable to other types.

[0042] Such as Figure 1As shown in the figure, the rotating hook box of a rotary sewing machine includes four parts: the rotating hook part A, the transmission part B, the cover part C, and the needle plate part D. The four parts are assembled together, and the motor operates to make the rotating hook work.

[0043] The transmission part B, the cover part C, and the needle plate part D are fixedly installed on the rotating hook part A by screws; the rotating hook part A is used for the overall assembly of the rotating hook box structure; the transmission part B is used to transfer the kinetic energy generated by the motor to the rotating hook; the cover part C is used to close the maintenance hole to ensure the sealing of the rotating hook cavity and prevent oil from splashing; the needle plate part D is used to fix the position of the needle plate hole of the sewing needle to facilitate the replacement of vulnerable parts.

[0044] As Figure 2 shown in the figure, the rotating hook part A includes: a rotating hook box body A1, a rotating hook mounting plate A2, a rotating hook A3, and a motor A4.

[0045] The rotating hook A3 is installed on the rotating hook mounting plate A2 by an internal hexagon screw, and then installed on the rotating hook box body A1 by an internal hexagon screw. The motor A4 is installed on the rotating hook box body A1 by a screw, thus completing the fixation of the required parts.

[0046] As Figure 3 shown in the figure, the transmission part B includes a rotating hook transmission shaft B1, a coupling B2, an integral bearing seat one B3, a pulley transmission shaft B4, a synchronous pulley B5, an integral bearing seat two B6, a sensor mounting seat B7, a sensor B8, a sensor induction piece B9, a synchronous belt B10, and a motor synchronous pulley B11.

[0047] The rotating hook transmission shaft B1 passes through the rotating hook A3 and is connected to the pulley transmission shaft B4 through the coupling B2. The integral bearing seat one B3, the synchronous pulley B5, and the integral bearing seat two B6 are passed through by the pulley transmission shaft B4 and fastened on the pulley transmission shaft B4 by set screws. The integral bearing seat one B3 and the integral bearing seat two B6 are installed on the rotating hook box body A1 by bolts. The sensor B8 is installed on the sensor mounting seat B7 by screws and then installed on the integral bearing seat two B6 by screws. The synchronous belt B10 passes through the synchronous pulley B5 and the motor synchronous pulley B11. The motor synchronous pulley B11 is installed on the motor A4 by a set screw. When the motor A4 rotates, it drives the synchronous belt B10 to make the synchronous pulley B5 rotate, thereby transmitting the power to the rotating hook A3 and the equipment works. Two bearing seats, namely the integral bearing seat one B3 and the integral bearing seat two B6, are used to double support the transmission part, and the stability of this part is greatly improved.

[0048] As Figure 4 shown in the figure, the cover part C includes a bearing seat cover plate C1, a rotating hook cover plate C2, a motor cover C3, a rotating hook shaft cover plate C4, a motor wheel cover plate C5, and a sensor cover plate C6. All components of this part are installed on the rotating hook box body A1 by screws to ensure the sealed state of the device, protect the safety of personnel, ensure the stability of the equipment, and keep the surrounding environment clean and tidy.

[0049] As shown Figure 5 in the figure, the needle plate part D includes a disk D1, a shuttle-changing iron plate D2, a needle plate D3, and a needle plate core D4.

[0050] The disk D1 is installed on the rotating hook mounting plate A2 by countersunk head screws. The shuttle-changing iron plate D2 is adsorbed on the rotating hook housing A1 by a magnet below. The needle plate D3 is installed on the rotating hook housing A1 by screws. The needle plate core D4 is installed on the needle plate D3 by countersunk head screws. This structure facilitates the positioning of the rotating disk and the replacement of different needle plate cores D4 to meet the requirements of the equipment.

[0051] Workflow:

[0052] The transmission part B of the rotating sewing machine rotating hook housing rotates driven by the motor A4, so that the rotating hook A3 works as required. The cover part C ensures that no foreign objects enter the rotating mechanism, ensures the safety of personnel, ensures that there is no splashing of internal oil leakage, and ensures the safe and stable operation of the equipment. The needle plate part D ensures that the equipment rotates within a specified diameter circle. At the same time, the needle plate core D4 can be replaced with different models to meet different customer requirements.

[0053] In summary, the utility model has the advantages of stable structure, high speed and efficiency, clean and tidy working environment, ensuring the safety of personnel during equipment operation, saving production costs, greatly reducing the number of parts, simple assembly, easy production, and being suitable for batch production of equipment.
