[0025] Example

[0026] like Figure 1 , Figure 2 As shown, this embodiment provides a transmission mechanism for a winding and unwinding turret, including a power unit, a winding unit and a unloading unit. The winding and unwinding turret includes a turning frame 4, and the transmission mechanism is arranged on the turning frame 4 and rotates with the turning frame 4.

[0027] Specifically, the power unit includes a motor 1, a reducer 12, a fixing plate 13 and a connecting assembly 14. The reducer 12 is connected to the motor 1 in a transmission manner. The specific connection method is not limited in this embodiment. The motor 1 can drive the first rotating shaft 121 of the reducer 12 to rotate.

[0028] The fixing plate 13 is provided with a slot 131, and the slot 131 extends radially along the first rotating shaft 121; the connecting assembly 14 includes a first bolt, a first nut matched with the first bolt, and a gasket; the reducer 12 is connected to the fixing plate 13, and the fixing plate 13 is connected to the flip frame 4 through the connecting assembly 14. Specifically, the flip frame 4 is provided with a first through hole, and the first bolt passes through the slot 131, the first through hole and the gasket in sequence, and is connected to the first nut, so that the fixing plate 13 and the flip frame 4 can be fixedly connected, and the flip frame 4 can drive the entire power unit to rotate; the slot 131 is provided to adjust the relative position of the fixing plate 13 and the flip frame 4. The first rotating shaft 121 of the reducer 12 is provided with a first gear 122, and the first gear 122 is coaxially arranged with the first rotating shaft 121.

[0029] The coiling unit is arranged adjacent to the power unit. Specifically, the coiling unit includes a coiling rotating shaft 21 and a mounting seat 22. The mounting seat 22 is connected to the flip frame 4. The mounting seat 22 is used to fix the coiling rotating shaft 21. The first end of the coiling rotating shaft 21 extends out of the mounting seat 22 and passes through the flip frame 4 to be connected to the air expansion chuck. The second end of the coiling rotating shaft 21 extends out of the mounting seat 22 for coiling. The coiling rotating shaft 21 is coaxially arranged with the first rotating shaft 121, and the direction of the connecting line between the coiling rotating shaft 21 and the first rotating shaft 121 in the vertical plane thereof is parallel to the extending direction of the slot 131. If the relative position of the fixing plate 13 and the flip frame 4 is adjusted, the relative distance between the coiling rotating shaft 21 and the first rotating shaft 121 is adjusted.

[0030] Furthermore, the coil rotating shaft 21 is provided with a second gear 212, the second gear 212 is in the mounting seat 22, and the second gear 212 and the first gear 122 are located in the same plane. In this embodiment, the first gear 122 and the second gear 212 are connected by a synchronous belt (not shown in the figure), and the synchronous belt is respectively engaged with the first gear 122 and the second gear 212. The emcee gear and the second gear 212 may not be provided, and the first rotating shaft 121 and the second rotating shaft are directly connected by a synchronous belt.

[0031] In this embodiment, when the motor 1 is started, the motor 1 drives the first rotating shaft 121 of the reducer 12 to rotate, and through the synchronous belt transmission connection, the winding rotating shaft 21 rotates with the first rotating shaft 121, thereby completing the winding operation.

[0032] As a further improvement of this embodiment, a protective frame is provided at the first gear 122, the second gear 212 and the synchronous belt to prevent accidental contact with the first gear 122, the second gear 212 or the synchronous belt to affect the coiling process.

[0033] The unloading unit includes a first cylinder 31 and a limit plate 32. The limit plate 32 is located at the second end of the coil rotating shaft 21 and is perpendicular to the coil rotating shaft 21. The limit plate 32 is provided with a second through hole 321. The second through hole 321 is adapted to the second end of the coil rotating shaft 21. The first cylinder 31 includes a cylinder body and a piston rod. The cylinder body is connected to the mounting seat 22. The end of the piston rod away from the cylinder body is connected to the limit plate 32. The axial direction of the piston rod is parallel to the axial direction of the coil rotating shaft 21. When the coiling is required, the piston rod of the first cylinder 31 retracts to a suitable position, so that the limit plate 32 moves to a suitable position. When the coiling is completed and the unloading is required, the piston rod extends outward, thereby pushing the limit plate 32 away from the coil rotating shaft 21, so as to carry out the unloading work. In this embodiment, one limit plate 32 is pushed by two first piston rods.

[0034] like Figure 3 The figure shows a schematic diagram of the structure in which the transmission mechanism is installed on the reel-up and reel-down turret. One flip plate can be equipped with two transmission mechanisms.

[0035] The transmission mechanism for winding and unwinding the winding turret provided in this embodiment has a power unit connected to the turning frame 4, and is turned over with the turning frame 4. The power unit and the winding unit are driven by a synchronous belt, thereby realizing the winding and unwinding work. Only one level of connection is required to transmit the power to the winding unit. Compared with the multi-level transmission of the prior art, the transmission efficiency can be significantly improved, and the transmission structure is simple, which can effectively reduce the cost. At the same time, it is easy to install and maintain. By adjusting the relative position of the power unit and the turning frame 4 through the slot 131, the relative distance between the winding rotating shaft 21 and the first rotating shaft 121 can be adjusted, that is, the tension of the synchronous belt is adjusted to make the tension of the synchronous belt within an appropriate range.
