[0035] In the embodiment, the two second guide wheels 6 are arranged on the two sides below the second synchronous wheel 3, and the other second guide wheel 6 is arranged above the side of the second synchronous wheel 3 away from the first synchronous wheel 2, so that the synchronous belt 4 passes through the second guide wheel 6 above the side of the second synchronous wheel 3 away from the first synchronous wheel 2 first, and then passes through the two second guide wheels 6 below the second synchronous wheel 3, and then passes through the second synchronous wheel 3, avoiding interference between the synchronous belt 4 and the second synchronous wheel 3, and facilitating the increase of the wrap angle of the synchronous belt 4 and the second synchronous wheel 3 to ensure sufficient transmission power and stability. The number of the second guide wheels 6 is not limited in the embodiment, which can be 4, 5 or more, and the number and position of the second guide wheels 6 can be set according to actual needs.

[0036] Specifically, the first guide wheel 5 and the second guide wheel 6 can be symmetrically arranged with the vertical line of the midpoint connecting line of the first synchronous wheel 2 and the second synchronous wheel 3 as the axis of symmetry, so that the whole is uniformly arranged, improving the stability of the synchronous belt 4 transmission process.

[0037] In one embodiment, as shown in Figure 2 The tensioner is located between the first synchronous wheel 2 and the second synchronous wheel 3.

[0038] In the embodiment, the tensioner can be arranged between the first synchronous wheel 2 and the second synchronous wheel 3, which can change the wrap angle of the synchronous belt 4 on the first synchronous wheel 2 and the second synchronous wheel 3 while adjusting the tension of the synchronous belt 4.

[0039] As a convertible embodiment, the tensioner can also be located between two adjacent first guide wheels 5.

At the same time, the first guide wheel 5 and the second guide wheel 6, the tensioning wheel are arranged on one of the connecting plates 1 and are spaced apart from the side wall of the other connecting plate 1 by a preset distance, so that the synchronous belt 4 can pass through the gap between them for replacement.

[0046] The principle of installing and dismounting the synchronous belt 4 in the turret mechanism provided in this embodiment is as follows: when the synchronous belt 4 needs to be installed, first, the light surface of the synchronous belt 4 faces inward, and the synchronous belt is wound on the three first guide wheels 5 in sequence through the gap between the first guide wheel and the side wall of the connecting plate 1, then the first guide wheel 5, and then the second guide wheel 6 in sequence, and then the tooth surface of the synchronous belt 4 is wound on the second synchronous wheel 3 and the first synchronous wheel 2 in sequence (the specific movement path is shown in Figure 2For example, starting from the first synchronous wheel 2, passing through the left lower first guide wheel 5 and the right lower first guide wheel 5 in turn, then from the right upper first guide wheel 5 to the left upper second guide wheel 6, and then passing through the left lower and right lower second guide wheels 6 in turn, and then passing through the tensioning wheel after bypassing the second synchronous wheel 3 from the left side of the second synchronous wheel 3 and returning to the first synchronous wheel 2), when the synchronous belt 4 is wound, the tensioning wheel is driven by the adjusting member to abut against the synchronous belt 4 and is adjusted to an appropriate tensioning degree, the synchronous belt 4 is tensioned to facilitate ensuring the stability of transmission; when disassembly is required, the tensioning wheel is driven by the adjusting member to move away from the synchronous belt 4, so that the synchronous belt 4 becomes loose, and then the synchronous belt 4 is pulled out through the gap between the first guide wheel, the second guide wheel and the side wall of the connecting plate 1, which is convenient and fast, and solves the technical problem that in the existing turret mechanism, when the synchronous belt 4 needs to be replaced due to damage, the driving shaft and the driven shaft usually need to be disassembled to replace the synchronous belt 4, which is time-consuming and laborious and affects the work efficiency.
