Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a tea shaping device. Background Art

[0002] During the processing of some teas, the tea leaves need to be flattened to improve the appearance of the finished tea.

[0003] The Chinese patent application number CN201520038707.1 discloses a tea-leaf forming machine. It includes a conveyor belt arranged on a frame, and two rollers with horizontal roller cores and mutually cooperating are arranged at the discharge end of the conveyor belt. The length direction of the rollers is arranged along the width direction of the conveyor belt and the discharge end is adjacent to the net surface of the drying net. The net surface of the drying net is flat and arranged on a moving mechanism. The moving mechanism drives the drying net to move left and right and forward and backward below the discharge end of the rollers. The tea leaves to be formed are spread on the conveyor belt. After the tea leaves are pinched and flattened by two mutually cooperating rollers, the formed tea leaves are spread on the drying net. The drying net is driven by the moving mechanism to move left and right and forward and backward. When the rollers flatten and shape the tea leaves, the tea leaves fall corresponding to the movement of the drying net, so that the tea leaves can be neatly and quickly arranged on the drying net. The tea-leaf forming machine can realize the automation of pinching and flattening and discharging of tea leaves, which significantly improves the production efficiency of tea leaves.

[0004] In the solution provided by the patent, two pressing rollers are arranged side by side, driving the tea leaves to fall into the top of the gap between the two pressing rollers, and driving the two pressing rollers to rotate in opposite directions to drive the tea leaves to pass through the gap. The tea leaves are squeezed and shaped during the process of passing through the gap, but the tea leaves can only be flattened, and cannot be made into strips. Therefore, the present application proposes a tea shaping device that can flatten tea leaves and make them present a strip structure. Utility Model Content

[0027] Among them, see Figure 1The shaping mechanism 1 is provided with a cylinder 101, a rotating rod 102, a lever 103 and a circular plate 104; the cylinder 101 is arranged horizontally and sealed at both ends, and the side walls of the top and bottom of the cylinder 101 are respectively provided with a first opening 101a and a second opening 101b communicated with the inside thereof; the rotating rod 102 is coaxially mounted in the cylinder 101, and the axial ends are respectively rotatably connected to the two sealed ends of the cylinder 101, at least two levers 103 are arranged in a ring around the axis of the rotating rod 102 inside the cylinder 101, and the rotating rod 102 and at least one circular plate 104 are coaxially mounted in ... The cylinder 101 is connected to the cylinder 101 by a shaft, and the side of each circular plate 104 is respectively connected to each lever 103, and the side of each lever 103 away from the rotating rod 102 is spaced from the inner wall of the cylinder 101 by a preset distance; the injection hopper 2 is arranged on the cylinder 101, the top of the injection hopper 2 is open and receives the tea leaves to be processed, and the inner bottom of the injection hopper 2 is connected to the first opening 101a; the discharge pipe 3 is arranged under the cylinder 101, one end of the discharge pipe 3 is connected to the second opening 101b, and the other end of the discharge pipe 3 is arranged at the input end of the external collection container or the downstream processing equipment. The tea leaves to be processed are continuously injected into the injection hopper 2, and at the same time, each lever 103 is driven to rotate around the axis of the rotating rod 102 from the first opening 101a to the second opening 101b, so as to continuously move the tea leaves at the first opening 101a and push them to the second opening 101b. During this process, the side of the lever 103 away from the rotating rod 102 will squeeze and flatten the tea leaves with the inner wall of the cylinder 101, and the tea leaves will present a strip structure when moving from the first opening 101a to the second opening 101b with the lever 103.

[0028] Further, see Figure 2 The shaping mechanism 1 is also provided with a first motor 105, a first driving wheel 106, a first driven wheel 107 and a first transmission belt 108. The rotating shaft of the first motor 105 is coaxially connected with the first driving wheel 106. One end of the rotating rod 102 extends through one end of the cylinder 101 and is coaxially connected with the first driven wheel 107. The first transmission belt 108 is tensioned outside the first driving wheel 106 and the first driven wheel 107. The first motor 105 is driven to do work to drive the first driving wheel 106 to rotate. Under the action of the first transmission belt 108, the first driven wheel 107 rotates with the first driving wheel 106, thereby driving the rotating rod 102 to rotate around its own axis.

[0029] Furthermore, the first opening 101a and the second opening 101b are both linear notches whose diameters are parallel to the axis of the cylinder 101, so as to process tea leaves in batches and in an orderly manner.

[0030] Furthermore, the bottom of the filling hopper 2 is a curved surface structure whose axis is parallel to the diameter of the first opening 101a, and the low position of the bottom of the filling hopper 2 is connected to the first opening 101a to prevent the tea leaves to be processed from piling up in the filling hopper 2.

The second roller 402 is arranged on one side of the axial direction of the cylinder 101. The conveyor belt 403 is stretched outside the first roller 401 and the second roller 402. The two ends of the axial direction of the first roller 401 and the second roller 402 are respectively connected to two support plates 404, and the bottom edge of each support plate 404 is connected to the bottom plate 405. Driving the first roller 401 or the second roller 402 to rotate around its own axis can drive the top surface of the conveyor belt 403 to move in one direction.

The rotating shaft of the second motor 406 is coaxially connected with the rotating shaft of the second driving wheel 407. One end of the first roller 401 passes through the support plate 404 and is coaxially connected with the second driven wheel 408. The second driving wheel 407 and the second driven wheel 408 are tensioned with a second transmission belt 409. Driving the second motor 406 to do work can drive the second driving wheel 407 to rotate. Under the action of the second transmission belt 409, the second driven wheel 408 rotates with the second driving wheel 407, thereby driving the first roller 401 to rotate around its own axis.

[0038] Further, see Figure 3 The conveying mechanism 4 is further provided with a support frame 410, which is arranged under the conveying belt 403 and connected to the bottom plate 405 to raise the bottom plate 405 and make one end of the conveying belt 403 adjacent to the cylinder 101 suspended in the air.

[0039] Further, see Figure 3 The filling hopper 2 and the cylinder 101 are connected to the bottom plate 405 through the connecting plate 411 so that the shaping mechanism 1 is suspended under the conveyor belt 403.

[0040] Optionally, the level of the second roller 402 is lower than that of the first roller 401 , so that the conveyor belt 403 is inclined and the material is conveyed to a high position.

[0041] In this embodiment, the structure formed by the support frame 410, the bottom plate 405 and the support plate 404 provides support while allowing the shaping mechanism 1 to be suspended below the end of the conveyor belt 403 facing the air, and the end of the conveyor belt 403 away from the shaping component is placed at the output end of the upstream processing equipment, and the second motor 406 is controlled to do work, which can continuously drive the top surface of the conveyor belt 403 to move from the second roller 402 to the direction close to the first roller 401, so as to continuously transport the tea leaves to be shaped to the filling hopper 2.
