Specifically, the linear conveying assembly 32 of the baking room rail 30 includes a first frame 321, a linear track, and a first drive motor. The linear track is provided on the first frame 321, and a double-speed chain 322 is provided in the linear track. The driving end of the first drive motor is connected to the double-speed chain 322 to drive the double-speed chain 322 to operate.

[0035] Furthermore, the double-speed chain 322 is set to two, and the two double-speed chains 322 are parallel to each other, and the first drive motor drives the two double-speed chains 322 to rotate at the same time, ensuring that when the conveying base plate 10 is in a straight conveying assembly, the conveying speeds on both sides of the conveying base plate 10 are consistent, the transportation process is smooth, and the shaking of the conveying base plate 10, especially the Christmas tree above the conveying base plate 10, is reduced.

[0037] See Figure 3-6 In some embodiments, the turning assembly 34 includes a second frame 341, on which an arc-shaped track is provided. The arc-shaped track includes a plurality of conical rollers 342 arranged in an arc shape, and the busbars of the plurality of conical rollers 342 are horizontal to form a transport plane, and the transport plane is flush with the upper surface of the double-speed chain 322.

The arc-shaped track includes a plurality of conical rollers 342 arranged in an arc shape. The busbars of the plurality of conical rollers 342 are horizontal to form a transport plane, and the transport plane is flush with the upper surface of the double-speed chain 324. The two ends of the arc-shaped track are respectively connected to a straight track. Specifically, the conveying inlet end of the arc-shaped track is corresponding to the conveying outlet end of the straight track behind the arc-shaped track, and the conveying outlet end of the arc-shaped track is corresponding to the conveying inlet end of another straight track in front of the arc-shaped track. The distance from the straight track to the axis of the adjacent conical roller 342 is less than half the width of the conveying base plate 10, wherein the width is the dimensional spacing of the conveying base plate 10 parallel to the conveying direction. Preferably, the distance between the axes of two adjacent conical rollers 342 is less than half the width of the conveying base 10, so that the conveying base 10 is always located above at least two conical rollers 342 when turning, thereby preventing the conveying base 10 from shaking, thereby causing the Christmas tree to shake and causing the undried spray pile on the Christmas tree to fall off.

[0051] Furthermore, the second frame 341 includes a first curved plate 341a and a second curved plate 341b, each having the same curvature.

[0053] Furthermore, the turning assembly 34 also includes a support roller 348, which is rotatably connected to the first arc plate and the second arc plate, and is spaced apart from the conical roller 342. The distance between the axis of the support roller 348 and the axis of the adjacent conical roller 342 or the support roller 348 is less than half the width of the conveying base plate 10. The support roller 348 is used to prevent the conveying base plate 10 from shaking during transportation above the conical roller 342.

[0054] Compared with the existing technology, the beneficial effects of the technical solution of the utility model are as follows:
