DETAILED DESCRIPTION

[0024] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the built-in power device of the composite motion roller 5 of the present invention is provided with a support shaft on the frame, and the support shaft includes a left support shaft 1 and a right support shaft 15, and a rotation power device is provided between the left support shaft 1 and the right support shaft 15. The rotation power device preferably adopts an outer rotor motor 4, and the left end output shaft of the outer rotor motor 4 is tightly connected to the left support shaft 1, and the right end output shaft is tightly connected to the right support shaft 15. When the outer rotor motor 4 is working, the motor shaft does not rotate, and the outer shell of the motor rotates. A power line is provided in the axis of the left support shaft 1 to supply power to the outer rotor motor 4. The outer shell of the outer rotor motor 4 is tightly connected to the flower basket frame 3, and the outer rotor motor 4 can drive the flower basket frame 3 to perform a rotary motion, and the flower basket frame 3 is movably connected to the left side with the left end cover 2. The flower basket frame 3 is a circular sleeve, and two symmetrical sliding grooves are opened along the axial direction to one end of the sleeve. Two symmetrical sliding blocks extend from one surface of the left end cover 2, and the sliding blocks and the sliding grooves form a sliding fit correspondingly. When the flower basket 3 rotates under the drive of the outer rotor motor 4, the left end cover 2 also rotates under the action of the sliding groove, that is, the roller 5 is driven to make a rotary motion. Since the flower basket 3 and the left end cover 2 also form a sliding fit, the left end cover 2 can move back and forth horizontally relative to the flower basket 3. An annular groove is provided on the other side of the left end cover 2, and a balancing block 20 can be installed in the annular groove.

[0026] A traverse power device is arranged on the right supporting shaft 15, and the traverse power device is connected to the transmission cam 16 to the right side, and the traverse power device can drive the transmission cam 16 to perform a rotational motion. The transmission cam 16 includes a wheel surface and a shaft cylinder connected in an integral manner, and the shaft cylinder extends from the center of the wheel surface and is coaxial with the wheel surface. The shaft cylinder is sleeved on the right supporting shaft 15 and can rotate freely around the right supporting shaft 15. A circle of grooves 21 is provided on the outer circumference of the shaft cylinder, and the grooves 21 on the outer circumference of the shaft cylinder are a circle of closed oblique rings, and have a reciprocating stroke of a certain length in the axial direction. The right end cover 12 is sleeved on the outer circumference of the shaft cylinder, and a roller 13 is fixed in the radial direction of the right end cover 12 by bolts. The roller 13 is installed on the right end cover 12 and extends into the groove 21 of the shaft cylinder. When the transmission cam 16 rotates relative to the right end cover 12, the roller 13 moves along the groove 21 on the shaft cylinder, so that the right end cover 12 reciprocates and moves laterally in the axial direction. The drum 5 is integrally arranged on the outer circumference from the left end cover 2 to the right end cover 12 , and the left end cover 2 and the right end cover 12 are fixedly connected to the two ends of the inner circumference of the drum 5 , respectively.

[0027] like Figure 4 As shown, the traverse power device is a two-stage planetary reduction device, including a first-stage planetary gear train and a second-stage planetary gear train of different sizes. The first-stage planetary gear train includes a first-stage outer gear ring 9, a first-stage planetary gear 8 and a first-stage sun gear 7, and the second-stage planetary gear train includes a second-stage outer gear ring 11, a second-stage planetary gear 17 and a second-stage sun gear 18. The first-stage outer gear ring 9 is fixedly connected to the inner periphery of the drum 5, and the first-stage planetary gear 8 is respectively meshed with the first-stage outer gear ring 9 and the first-stage sun gear 7, and the first-stage sun gear 7 is fastened to the right support shaft 15 through a key rod 19. The second-stage outer gear ring 11 is fixedly connected to the edge of the transmission cam 16, and the second-stage planetary gear 17 is respectively meshed with the second-stage outer gear ring 11 and the second-stage sun gear 18, and the second-stage sun gear 18 is fastened to the right support shaft 15 through a key rod 19. A planet carrier 10 is arranged between the first-stage sun gear 7 and the second-stage sun gear 18. The planet carrier 10 is connected to the right support shaft 15 through a bearing, and the bearing is fastened to the right support shaft 15 through a key rod 19. That is, the first-stage sun gear 7, the bearing, and the second-stage sun gear 18 are fastened to the right support shaft 15 through the same key rod 19. A semi-threaded bolt is arranged in the axis of the first-stage planetary gear 8, and the screw of the semi-threaded bolt passes through the first-stage planetary gear 8 and is fastened to the planet carrier 10, and the first-stage planetary gear 8 can rotate freely around the screw. A semi-threaded bolt is arranged in the axis of the second-stage planetary gear 17, and the screw of the semi-threaded bolt passes through the second-stage planetary gear 17 and is fastened to the planet carrier 10, and the second-stage planetary gear 17 can rotate freely around the screw. Locking rings 14 are respectively arranged on the right support shaft 15 on the left side of the first-stage sun gear 7 and the right side of the transmission cam 16 to limit the left and right lateral movement of the first-stage planetary gear train, the second-stage planetary gear train, and the transmission cam 16.

[0028] One wheel edge of the transmission cam 16 is tightly connected to the second-level outer gear ring 11, and the other side is a shaft cylinder. The two-stage planetary reduction device causes the rotation of the transmission cam 16 to produce a speed difference relative to the rotation speed of the drum 5, thereby causing the right end cover 12 to reciprocate laterally in the axial direction of the right support shaft 15. Since the right end cover 12, the drum 5, the first-level outer gear ring 9 and the left end cover 2 are fixedly connected together, when the right end cover 12 moves laterally back and forth, it will drive the drum 5 and the left end cover 2 to move together, and the sliding block of the left end cover 2 will form a sliding fit with the sliding groove of the flower basket 3, and relative sliding will also occur between the first-level outer gear ring 9 and the first-level planetary gear 8. A support plate 6 is fixedly connected to the inner wall of the drum 5 between the traverse power device and the rotation power device. The support plate 6 is set on the right support shaft 15 through a copper sleeve. The support plate 6 can rotate freely around the right support shaft 15 and can reciprocate along the axial direction of the right support shaft 15.

[0029] When the present invention is implemented, a left support shaft 1 and a right support shaft 15 are arranged on the frame, and an outer rotor motor 4 is arranged between the left support shaft 1 and the right support shaft 15. When the outer rotor motor 4 is working, the motor shaft does not rotate, and the outer shell of the motor rotates, and the rotation speed of the outer rotor motor 4 is set to V1. The outer shell of the outer rotor motor 4 is tightly connected to the flower basket frame 3, and the sliding block of the left end cover 2 and the sliding groove of the flower basket frame 3 form a sliding fit. When the flower basket frame 3 rotates under the drive of the outer rotor motor 4, the left end cover 2 also rotates under the action of the sliding groove, and drives the drum 5 to make a rotary motion. The right end cover 12 is fixedly connected to the right end of the drum 5, and the rotation speed of the drum 5 is V1, and the rotation speed of the right end cover 12 is also V1.

[0030] A traverse power device is arranged on the right supporting shaft 15, including a first-stage planetary gear train and a second-stage planetary gear train. The first-stage outer gear ring 9 is fixedly connected to the inner circumference of the drum 5, and the second-stage outer gear ring 11 is fixedly connected to the edge of the transmission cam 16. The first-stage sun gear 7, the bearing of the planet carrier 10, and the second-stage sun gear 18 are fastened to the right supporting shaft 15 through a key rod 19. The first-stage planetary gear 8 and the second-stage planetary gear 17 are installed on the left and right sides of the planet carrier 10 through semi-threaded bolts. When the first-stage planetary gear 8 rotates, it drives the planet carrier 10 and the second-stage planetary gear 17 to rotate. Relative sliding can occur between the first-stage outer gear ring 9 and the first-stage planetary gear 8. One wheel surface edge of the transmission cam 16 is fastened to the second-stage outer gear ring 11, and the other side is a shaft cylinder. The shaft cylinder is sleeved on the right supporting shaft 15 and can rotate freely around the right supporting shaft 15. Therefore, the rotation speed of the first-stage outer gear ring 9 is V1, and after the conversion of the first-stage planetary gear train and the second-stage planetary gear train, the rotation speed of the transmission cam 16 is V2. Since there is a speed difference V1-V2 between the rotation speed V1 of the right end cover 12 and the rotation speed V2 of the transmission cam 16, when the transmission cam 16 rotates, the roller 13 and the transmission cam 16 move relative to each other, and the roller 13 rolls along the groove 21, so that the right end cover 12 reciprocates in the axial direction of the right support shaft 15.

[0031] Since the right end cover 12, the roller 5, the first-stage outer gear ring 9 and the left end cover 2 are fixedly connected together, when the right end cover 12 moves back and forth laterally, it will drive the roller 5 and the left end cover 2 to move together, and the sliding block of the left end cover 2 will form a sliding fit with the sliding groove of the flower basket frame 3, and relative sliding will also occur between the first-stage outer gear ring 9 and the first-stage planetary gear 8. Therefore, under the action of the rotating power device and the lateral power device, the roller 5 performs a composite motion of rotation and lateral reciprocating movement at the same time. In order to ensure the balance and stability of the equipment, a balancing block 20 can be installed in the annular groove of the left end cover 2.

[0032] The above description is an explanation of the present invention, not a limitation of the present invention. The present invention may be modified in any form without violating the spirit of the present invention. For example, the traverse power device is also an outer rotor motor, and its housing is fixedly connected to the edge of the wheel surface of the transmission cam. The speed of the traverse power device driving the transmission cam is set to V2, and the speed difference V1-V2 between the right end cover and the transmission cam can also be generated to achieve the composite motion of the rotation and traverse of the roller.
