Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0031] Please refer to Figures 1 to 9 As shown, a tea spreading machine provided by the utility model is now described. The tea spreading machine includes a mounting frame 1, an upper roller assembly 2, a mesh chain 3, and a deformable connecting portion 4. The upper roller assembly 2 includes a flip frame 21, an upper retaining roller 22, and a flip driver 23. The upper retaining roller 22 is rotatably matched with the flip frame 21. One side of the flip frame 21 is hinged to the mounting frame 1. The hinge axis of the flip frame 21 and the mounting frame 1 is along the length direction of the mounting frame 1. The flip driver 23 is connected to the mounting frame 1. The flip driver 23 is a driving device that outputs linear motion power. The output end 231 of the flip driver 23 is movably connected to the flip frame 21, as shown in FIG. Figure 8 As shown, when the output end 231 of the flip driver 23 is extended to the right position, the flip frame 21 can be pushed to flip upward on the mounting frame 1, so that a low position area 7 is formed on the flip frame 21 near the hinged side of the mounting frame 1, and a high position area 8 is formed on the flip frame 21 away from the hinged side of the mounting frame 1; Fig. 9As shown, when the output end 231 of the flip driver 23 is retracted into place, the flip frame 21 can be pulled to flip downward on the mounting frame 1, so that a high position area 8 is formed on the flip frame 21 close to the side hinged to the mounting frame 1, and a low position area 7 is formed on the flip frame 21 away from the side hinged to the mounting frame 1. Two upper roller assemblies 2 are arranged on the mounting frame 1 on the same horizontal plane. The two upper roller assemblies 2 are symmetrically arranged on the opposite sides of the mounting frame 1 with respect to the length direction of the mounting frame 1. The mesh chain 3 has two, and the two mesh chains 3 are respectively arranged on the upper retaining rollers 22 of the two upper roller assemblies 2, and the two mesh chains 3 are connected by a deformation connection part 4, and are connected between the two mesh chains 3 by the deformation connection part 4. The deformation connection part 4 is extended and contracted to adapt to the mutual approach or distance of the two mesh chains 3, so that the mesh chain 3 can follow the flip frame 21 to flip up and down, as shown in FIG. Figure 8 As shown in FIG. 1 , when the turning frame 21 turns up, the middle position of the two mesh chains 3 is higher than the outer sides of the two mesh chains 3, so that the tea leaves placed on the mesh chains 3 turn to the outer sides of the two lower mesh chains 3, as shown in FIG. Fig. 9 As shown, when the turning frame 21 turns down, the middle position of the two mesh chains 3 is lower than the outer sides of the two mesh chains 3, so that the tea leaves placed on the mesh chains 3 are turned toward the middle of the two lower mesh chains 3. Without applying mechanical external force to the tea leaves, the tea leaves are turned up and down alternately following the turning frame 21 to achieve the turning of the tea leaves, thereby solving the problem of mechanical damage that is easy to occur when turning tea leaves on the existing tea spreading machines.

[0032] like Figure 2 and Figure 5 As shown, in some of the embodiments, a plurality of upper retaining rollers 22 are arranged along the length direction on the turning frame 21 to keep the upper end surface of the mesh chain 3 wound around the upper retaining rollers 22 to form a flat surface for spreading tea leaves.

[0033] like Figure 2 and Figure 5 As shown, in some embodiments, a gap 6 between the two turning frames 21 is provided between the two upper roller assemblies 2, so that the width of the gap 6 between the two turning frames 21 can be changed when the turning frames 21 turn up or down.

[0034] like Figure 1 and Figure 4 As shown, in some embodiments, a plurality of lower retaining rollers 5 rotatably matched with the mounting frame 1 are provided on the mounting frame 1 and below the upper roller assembly 2, the mesh chain 3 is passed around one of the upper retaining rollers 22 and downwardly arranged on the lower retaining roller 5, and the other mesh chain 3 is passed around the other upper retaining roller 22 and downwardly arranged on the lower retaining roller 5, so that the mesh chain 3 is simultaneously arranged on the upper retaining roller 22 and the lower retaining roller 5, so as to avoid the flipping drive 23 from interfering with the deformable connecting portion 4 connected between the two mesh chains 3.

[0035] like Figure 4 and Figure 6 As shown, in some embodiments, in order to realize the hinge connection between one side of the flip frame 21 and the mounting frame 1, a hinge part 211 is provided on the flip frame 21 and close to the side of the mounting frame 1, and the flip frame 21 is hinged to the mounting frame 1 through the hinge part 211.

[0036] like Figure 4 and Figure 7 As shown, in some embodiments, the output end 231 of the flip driver 23 is hingedly matched with the flip frame 21 through the hinge part 212, and the flip driver 23 is hinged on the mounting frame 1 through the hinge part 3 232. When the flip driver 23 drives the output end 231 to extend and retract, the flip frame 21 is pulled by the output end 231 to flip around the hinge part 1 211 on the mounting frame 1. The design of the hinge part 3 232 and the hinge part 2 212 enables the flip driver 23 to be always connected to the flip frame 21, and at the same time enables the flip driver 23 to adapt to the flipping movement of the flip frame 21.

[0037] In some embodiments, the tilt actuator 23 is a pneumatic cylinder.

[0038] In some embodiments, the deformable connecting portion 4 is made of a flexible and elastic rubber material, so that the deformable connecting portion 4 has the ability to extend and deform.

[0039] like Figure 1 As shown, in some of the embodiments, a side block 11 is provided on the side of the mounting frame 1 to prevent the tea leaves on the mesh chain 3 from spilling from the side of the mounting frame 1. In addition, a tail block 12 is provided at one end of the mounting frame 1. The tail block 12 is used to cooperate with the side block 11 to enclose the tea leaves on the upper end surface of the mesh chain 3. It can be understood that the tail block 12 can be set to rise and fall relative to the mounting frame 1, so that the tail block 12 can be raised and evacuated from the mesh chain 3 when needed, so that the mesh chain 3 can continue to move the tea leaves axially.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
