[0119] For example, Figure 8 As shown, the utility model also includes that the driven seat 4 includes:

[0120] The secondary base 401 is connected to the tail end of the aluminum profile 164;

[0129] like Figure 1 , 9As shown, the flat top chain turning device of the present application is mainly composed of a turning track, a motor assembly 2, a driving seat 3, and a driven seat 4. The conveying medium is a flat top chain 17. Through friction, the workpiece turns 180° above the flat top chain 17 and is conveyed from one conveyor line to another parallel conveyor line. When a line with a smaller turning radius is required, the single arc turning track 1, the motor assembly 2, the driving seat 3, and the driven seat 4 cooperate to operate;

[0130] When a line body with a larger turning radius is required, the single arc turning track 1 can be replaced by two sets of 90° turning tracks 5, and an intermediate straight track 6 is set between the two sets of 90° turning tracks 5. The two sets of 90° turning tracks 5, the intermediate straight track 6, the motor assembly 2, the driving seat 3 and the driven seat 4 cooperate to form a flat-top chain double-arc turning structure, which can enable the workpiece to be transported 180°. During this period, the turning radius of the double-arc turning track can be adjusted by lengthening or shortening the length of the intermediate straight track 6 according to actual use requirements, which has better applicability. A single set of 90° turning tracks 5 can also be used to enable the workpiece to make a 90° turn.

[0131] The 90° turning track 5 and the middle straight track 6 have the same structural components as the single arc turning track 1 except that the angles are different.
