Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea withering and spreading conveyor rack. Background Technique

[0002] Black tea belongs to the category of fully fermented tea. It is made from the buds and leaves of tea trees and is refined through typical technological processes such as withering, rolling, fermentation, and drying. The withering process is one of the key processes. Under certain conditions, the fresh tea leaves evenly lose an appropriate amount of moisture, reducing the cell turgor, softening the leaf quality, facilitating rolling into strips, and creating conditions for subsequent rolling.

[0003] After retrieval, a utility model with the Chinese patent publication number CN210248213U discloses a tea withering and spreading conveyor rack, including a base and a main body frame. On both sides inside the main body frame, support plates are evenly and fixedly installed, and rollers are rotatably installed on the support plates. A mesh plate is slidably installed on the rollers. A baffle is fixedly installed on the back of the support plate, and a fixing plate is fixedly installed on the top of the support plate. On one side outside the main body frame, a tool cavity is fixedly installed.

[0004] The above device realizes the effect of accelerating withering by blowing air with the blower at the bottom. However, due to the different distances from the blower and the blockage of each mesh plate, the wind speed becomes lower and lower upwards, resulting in different evaporation speeds of the moisture of the tea leaves at different positions, and thus different withering effects of the tea leaves at each position. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tea withering and spreading conveyor rack to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tea withering and spreading conveyor rack includes an installation rack. A placing component is installed inside the installation rack. The placing component includes a round hole opened in the upper half of the installation rack. A turntable is installed inside the round hole. The turntable is centered with the round hole and can rotate relatively. On one outer wall of the turntable, a plurality of installation rods are fixedly connected, and the plurality of installation rods are equidistantly distributed. A placing frame is rotatably sleeved outside each of the plurality of installation rods. A plurality of mesh holes are provided at the bottom of each of the plurality of placing frames.

[0007] As a further preference of this technical solution, a toothed ring is coaxially fixed on one outer wall of the turntable. A first motor is fixedly installed at the bottom of one outer wall of the installation rack. A gear is coaxially fixed on the rotating shaft of the first motor. The gear meshes with the toothed ring.

[0008] Enable multiple storage frames to move at a constant speed, so as to ensure that the tea leaves inside can be evenly blown by hot air, avoid the problem of different withering degrees caused by different wind speeds at different positions, and evenly sprinkle the tea leaves to be withered inside multiple storage frames. Since the connection position between the storage frame and the installation rod is at the top position, and the storage frame and the installation rod are rotatably connected, under the action of gravity, it can be ensured that each storage frame always keeps the opening facing upward. Then start the first motor on one side of the installation frame. The first motor drives the gear to rotate. The gear can drive the turntable to rotate inside the installation frame through the toothed ring engaged with it. The turntable will also drive the storage frame to continuously move through the installation rod, so as to ensure that the tea leaves inside multiple storage frames can be evenly blown by hot air.

[0009] As a further optimization of this technical solution, an acceleration component is installed inside the installation frame, and the acceleration component is located in the middle position of the installation frame.

[0010] As a further optimization of this technical solution, the acceleration component includes an air outlet pipe placed on the inner wall of the bottom of the installation frame. A plurality of air outlet holes are arranged on the outer wall of the top of the air outlet pipe. One side outer wall of the air outlet pipe is fixedly connected with an extension block. A reciprocating lead screw is threadedly connected inside the extension block, and a convex block adapted to the reciprocating lead screw is arranged inside the extension block. One end of the reciprocating lead screw is rotatably connected to the inner wall of one end of the installation frame. A limiting rod is fixedly connected to the inner wall of one end of the installation frame. The extension block is slidably sleeved outside the limiting rod. A second motor is fixedly installed on the inner wall of the bottom of the installation frame, and the rotating shaft of the second motor is coaxially fixed with the reciprocating lead screw.

[0011] The hot air is sprayed upward from the opening of the air outlet pipe. At the same time, start the second motor inside the installation frame. The second motor drives the reciprocating lead screw to rotate. The extension block will move left and right reciprocally under the drive of the reciprocating lead screw and the cooperation of the limiting rod. Then the air outlet pipe will also be driven to move synchronously, so as to ensure that the tea leaves at the multi-channel air flow gap can also be blown by hot air, further increasing the withering effect.

[0012] As a further optimization of this technical solution, a hot air blower is fixedly installed on one side of the inner wall of the bottom of the installation frame, and the same connecting pipe is fixedly inserted between the hot air blower and the air outlet pipe.

[0013] As a further optimization of this technical solution, a baffle is rotatably connected to the inner walls at both ends of each storage frame. Magnetic blocks are arranged at both ends of the outer wall of one side of the plurality of baffles, and a metal sheet adapted to the magnetic blocks is arranged inside the storage frame.

[0014] As a further optimization of this technical solution, the transmission ratio between the gear and the toothed ring is greater than one.

[0015] The utility model provides a tea withering and spreading conveyor rack, which has the following beneficial effects:

[0016] (1) The utility model ensures that multiple storage frames can move at a uniform speed by setting up a storage component, thereby guaranteeing that the tea leaves therein can be evenly blown by hot air, avoiding the problem of different withering degrees caused by different wind speeds at different positions. The tea leaves to be withered are evenly sprinkled inside multiple storage frames. Since the connection position between the storage frame and the mounting rod is at the top position and the storage frame and the mounting rod are rotatably connected, under the action of gravity, it can be ensured that each storage frame always keeps the opening facing upwards. Then, start the first motor on one side of the mounting frame. The first motor drives the gear to rotate, and the gear drives the turntable to rotate inside the mounting frame through the toothed ring meshing with it. The turntable drives the storage frame to continuously move through the mounting rod, thereby ensuring that the tea leaves in multiple storage frames can all be evenly blown by hot air.

[0017] (2) The utility model further improves the withering effect by setting up an acceleration component. The hot air is sprayed upwards from the opening of the air outlet pipe. At the same time, start the second motor inside the mounting frame. The second motor drives the reciprocating lead screw to rotate. The extension block will move left and right reciprocally under the drive of the reciprocating lead screw and the cooperation of the limiting rod. Further, the air outlet pipe will be driven to move synchronously, so as to ensure that the tea leaves at the multi-channel air flow gap can also be blown by hot air.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0024] The present utility model provides the following technical solutions: AsFigure 1 and Figure 2 As shown in Figure 2 , in this embodiment, a tea withering and spreading conveyor rack includes a mounting rack 1, and is characterized in that: a containing component 6 is installed inside the mounting rack 1. The containing component 6 includes a round hole opened in the upper half of the mounting rack 1. Inside the round hole, a turntable 601 is installed. The turntable is centered with the round hole and can rotate relatively. On one outer wall of the turntable 601, a plurality of mounting rods 602 are fixedly connected, and the plurality of mounting rods 602 are equidistantly distributed. A containing frame 603 is rotatably sleeved outside each of the plurality of mounting rods 602, and a plurality of mesh holes are provided at the bottoms of the plurality of containing frames 603.

[0025] On one outer wall of the turntable 601, a toothed ring 604 is coaxially fixed. At the bottom of one outer wall of the mounting rack 1, a first motor 605 is fixedly installed. On the coaxial shaft of the first motor 605, a gear 606 is coaxially fixed. The gear 606 meshes with the toothed ring 604.

[0026] Evenly sprinkle the tea leaves to be withered into the plurality of containing frames 603. Since the connection position between the containing frame 603 and the mounting rod 602 is at the top position, and the containing frame 603 and the mounting rod 602 are rotatably connected, under the action of gravity, it can be ensured that each containing frame 603 always keeps the opening facing upwards. Then, start the first motor 605 on one side of the mounting rack 1. The first motor 605 drives the gear 606 to rotate. The gear 606 can drive the turntable 601 to rotate inside the mounting rack 1 through the toothed ring 604 engaged with it. The turntable 601 drives the containing frame 603 to continuously displace through the mounting rod 602, so as to ensure that the tea leaves in the plurality of containing frames 603 can all be evenly blown by the hot air.

[0027] As Figure 1 and Figure 3 shown in Figure 1 , an accelerating component 7 is installed inside the mounting rack 1, and the accelerating component 7 is located at the middle position of the mounting rack 1.

[0028] The accelerating component 7 includes an air outlet pipe 701 placed on the inner wall of the bottom of the mounting rack 1. On the top outer wall of the air outlet pipe 701, a plurality of air outlet holes are provided. On one outer wall of the air outlet pipe 701, an extension block 702 is fixedly connected. Inside the extension block 702, a reciprocating lead screw 704 is threadedly connected, and inside the extension block 702, a convex block adapted to the reciprocating lead screw 704 is provided. One end of the reciprocating lead screw 704 is rotatably connected to the inner wall of one end of the mounting rack 1. A limiting rod 703 is fixedly connected to the inner wall of one end of the mounting rack 1. The extension block 702 is slidably sleeved outside the limiting rod 703. A second motor 705 is fixedly installed on the inner wall of the bottom of the mounting rack 1, and the coaxial shaft of the second motor 705 and the reciprocating lead screw 704 are coaxially fixed.

[0029] A hot air blower 2 fixedly installed on one side of the inner wall of the bottom of the mounting rack 1 is fixedly inserted with the same connecting pipe 3 between the hot air blower 2 and the air outlet pipe 701.

[0030] Hot air is sprayed upward from the opening of the air outlet pipe 701. At the same time, the second motor 705 inside the mounting frame 1 is started. The second motor 705 drives the reciprocating lead screw 704 to rotate. The extension block 702 will reciprocate left and right under the drive of the reciprocating lead screw 704 and the cooperation of the limit rod 703. Furthermore, the air outlet pipe 701 will also be driven to move synchronously, so as to ensure that the tea leaves at the multi-channel air flow gap can also be blown by hot air, further enhancing the withering effect.

[0031] As Figure 2 and Figure 4 shown, a baffle 4 is rotatably connected to the inner walls at both ends of each of the multiple containing frames 603, making it more convenient to discharge the withered tea leaves. Magnetic blocks 5 are provided at both ends of the outer wall on one side of each of the multiple baffles 4, and metal sheets adapted to the magnetic blocks 5 are arranged inside the containing frames 603, making the connection state more stable.

[0032] As Figure 2 shown, the transmission ratio between the gear 606 and the toothed ring 604 is greater than one, so that the rotation speed of the turntable 601 will not be too fast, and the resistance received by the first motor 605 during the driving process is smaller.

[0033] The present utility model provides a tea withering and spreading conveyor rack, and the specific working principle is as follows:

[0034] When the device works, the tea leaves to be withered are evenly sprinkled inside the multiple containing frames 603. Since the connection position between the containing frames 603 and the mounting rods 602 is at the top position, and the containing frames 603 and the mounting rods 602 are rotatably connected, under the action of gravity, it can be ensured that each containing frame 603 always maintains the state with the opening facing upward. Then, the first motor 605 on one side of the mounting frame 1 is started. The first motor 605 drives the gear 606 to rotate. The gear 606 can drive the turntable 601 to rotate inside the mounting frame 1 through the toothed ring 604 engaged with it. The turntable 601 will also drive the containing frames 603 to continuously displace through the mounting rods 602, so as to ensure that the tea leaves inside the multiple containing frames 603 can all be evenly blown by hot air. Then, the hot air blower 2 inside the mounting frame 1 is started. The hot air generated by the hot air blower 2 can enter the air outlet pipe 701 through the connecting pipe 3. Then, the hot air is sprayed upward from the opening of the air outlet pipe 701. At the same time, the second motor 705 inside the mounting frame 1 is started. The second motor 705 drives the reciprocating lead screw 704 to rotate. The extension block 702 will reciprocate left and right under the drive of the reciprocating lead screw 704 and the cooperation of the limit rod 703. Furthermore, the air outlet pipe 701 will also be driven to move synchronously, so as to ensure that the tea leaves at the multi-channel air flow gap can also be blown by hot air, further enhancing the withering effect.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
