Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a withering device for tea processing. Background Technology
[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea plant. Because tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, and these substances are beneficial to health, tea beverages have become one of the world's three major beverages. Fresh tea leaves need to undergo withering after picking to promote the activity of enzymes in the fresh leaves, thus requiring the use of specialized withering equipment.
[0003] Chinese utility model patent CN220326703U discloses a high-efficiency withering device. This device uses a motor to drive a bracket to rotate continuously, which in turn drives a tray on which tea leaves are laid to rotate at a uniform speed, thereby achieving the purpose of uniform withering of tea leaves. In actual use, the tea leaves tend to pile up and cover each other during the laying process. Furthermore, the device lacks an integrated structure to move the tea leaves, which affects the withering effect and reduces the processing quality of the tea. Therefore, we provide a withering device for tea processing. Utility Model Content
[0004] To address the problem in the aforementioned background technology that the difficulty in manipulating the laid tea leaves affects the withering effect, this utility model provides a withering device for tea processing.
[0005] This utility model is achieved using the following technical solution:
[0006] A withering device for tea processing includes a box and a toggle assembly. The inside of the box is rotatably connected to a frame via a rotating shaft. Two sets of holding mesh frames are provided on the frame. A motor is fixedly connected to the top of the box, and the end of the motor rotor is coaxially fixedly connected to the rotating shaft. A drying hot air fan is fixedly connected to the back of the box. The air outlet of the drying hot air fan is fixedly connected to a Y-shaped air inlet pipe, and the air outlet of the Y-shaped air inlet pipe is connected to both sides of the box.
[0007] The actuating assembly includes two sets of sliding rods symmetrically fixedly connected above the holding frame. Sliding blocks are slidably connected to the outer sides of both sliding rods. The bottom of the two sets of sliding blocks on the same side is fixedly connected to the same connecting plate. Actuating rods are fixedly connected at equal intervals to the bottom of the connecting plate. A crossbar is fixedly connected to the top of the connecting plate through a connecting seat, and the crossbar is slidably connected to the frame. A roller is rotatably connected to the end of the crossbar through a mounting seat. A spring is sleeved on the outside of the crossbar. Two sets of annular guide rails are fixedly connected to the inside of the box through a bracket. Arc-shaped protrusions are fixedly connected circumferentially at equal intervals on the annular guide rails.
[0008] In this utility model, a bidirectional lead screw is rotatably connected to the bottom of the holding mesh frame, and movable blocks are threaded to both sides of the bidirectional lead screw. Two sets of support plates are symmetrically arranged at the bottom of the holding mesh frame. The support plates and the movable blocks on the same side are symmetrically hinged to each other by hinges. Baffles are provided on both sides of the top of the holding mesh frame, and the baffles are fixedly connected to the frame.
[0009] In this invention, the two ends of the spring are fixedly connected to the frame and the mounting base, respectively.
[0010] In this invention, guide rods are fixedly connected to both sides of the bidirectional lead screw, and the guide rods are slidably connected to the moving block.
[0011] In this invention, two sets of positioning columns are symmetrically fixedly connected to the top of the support plate.
[0012] In this invention, two sets of positioning holes are provided on both sides of the bottom of the holding frame.
[0013] In this invention, two sets of guide blocks are symmetrically fixedly connected to one side of the support plate, and guide grooves are provided on the frame at the positions corresponding to the guide blocks and are slidably connected to the guide blocks.
[0014] Beneficial effects:
[0015] The withering device for tea processing described in this utility model uses a motor to drive the frame to rotate, which in turn rotates the tea leaves inside the basket to ensure uniform withering. Simultaneously, the frame rotation causes rollers to roll on a circular guide rail. When the rollers roll onto the arc-shaped protrusion, the sliding engagement between the crossbar and the frame, and between the slider and the sliding rod, pushes two sets of connecting plates to move towards each other. This causes the equidistant actuating rods on both sides to move towards each other, actuating the tea leaves inside the basket. At this time, the springs are compressed. When the rollers roll away from the arc-shaped protrusion, the springs rebound, causing the actuating rods on both sides to automatically reset, thus amplifying the tea leaves a second time. This effectively avoids the problem of difficulty in actuating the laid-out tea leaves, which would affect the withering effect.
[0016] In this invention, the positioning posts and positioning holes enable the quick positioning and placement of the holding mesh frame. Simultaneously, by rotating the bidirectional lead screw, two sets of moving blocks move in opposite directions. With the hinged action between the moving blocks, the support plate, and the connecting rod, and the sliding action between the guide block and the guide groove, the holding mesh frame can be pushed upward until it contacts the baffle, thereby achieving the fixing effect of the holding mesh frame and preventing it from easily detaching during rotation, thus ensuring the stability of the tea leaves during withering.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0024] Example 1:
[0025] Please combine Figure 1-5 A withering device for tea processing includes a box body 1. Inside the box body 1, a frame 2 is rotatably connected via a rotating shaft. Two sets of holding mesh frames 3 are set on the frame 2. A motor is fixedly connected to the top of the box body 1, and the end of the motor rotor is coaxially fixedly connected to the rotating shaft. A drying hot air fan is fixedly connected to the back of the box body 1. The air outlet of the drying hot air fan is fixedly connected to a Y-shaped air inlet pipe 4, and the air outlet of the Y-shaped air inlet pipe 4 is connected to both sides of the box body 1.
[0026] A stirring assembly for stirring tea leaves includes two sets of sliding rods 101 symmetrically fixedly connected above the holding frame 3. Sliding blocks are slidably connected to the outer sides of both sides of the sliding rods 101. The bottom of the two sets of sliding blocks on the same side is fixedly connected to the same connecting plate 102. A stirring rod 103 is fixedly connected at equal intervals to the bottom of the connecting plate 102. A crossbar 104 is fixedly connected to the top of the connecting plate 102 through a connecting seat, and the crossbar 104 is slidably connected to the frame 2. A roller 105 is rotatably connected to the end of the crossbar 104 through a mounting seat. A spring 106 is sleeved on the outside of the crossbar 104. The two ends of the spring 106 are fixedly connected to the frame 2 and the mounting seat, respectively. Two sets of annular guide rails 107 are fixedly connected to the inside of the box 1 through a bracket. Arc-shaped protrusions 108 are fixedly connected at equal intervals circumferentially on the annular guide rails 107.
[0027] A bidirectional lead screw 201 is rotatably connected to the bottom of the holding frame 3. Moving blocks 202 are threadedly connected to both sides of the bidirectional lead screw 201. Two sets of support plates 203 are symmetrically arranged at the bottom of the holding frame 3. The support plates 203 and the moving blocks 202 on the same side are symmetrically hinged to the connecting rods 204 through hinges. Baffles 205 are provided on both sides of the top of the holding frame 3 and are fixedly connected to the frame 2. Two sets of positioning posts 207 are symmetrically fixedly connected to the top of the support plates 203. Two sets of positioning holes are opened on both sides of the bottom of the holding frame 3. Two sets of guide blocks 208 are symmetrically fixedly connected to one side of the support plates 203. Guide grooves are opened on the frame 2 at the positions corresponding to the guide blocks 208 and are slidably connected to the guide blocks 208, which can play a certain guiding role in the vertical movement of the support plates 203.
[0028] The tea leaves are laid inside the holding frame 3, and then the holding frame 3 is placed on two sets of support plates 203 with the positioning pins 207 inserted into the positioning holes. Then, the bidirectional lead screw 201 is rotated, causing the two sets of moving blocks 202 to move in opposite directions. Through the hinged engagement between the moving blocks 202, the support plates 203, and the connecting rod 204, and the sliding engagement between the guide block 208 and the guide groove, the holding frame 3 is pushed upwards until it contacts the baffle 205, thus fixing the holding frame 3 and preventing it from easily detaching during subsequent rotation, ensuring the stability of the tea leaves during withering. Afterwards, the drying hot air blower and motor are started. The drying hot air blower delivers the generated hot air to the chamber 1 through the Y-shaped air inlet pipe 4 to dry the tea leaves, while the motor drives the frame 2 to rotate. The rotation of the frame 2 moves the tea leaves inside the holding frame 3. The frame 2 rotates together to ensure uniform withering. At the same time, the rotation of the frame 2 will also drive the roller 105 to roll on the annular guide rail 107. When the roller 105 rolls to the arc-shaped protrusion 108, the sliding cooperation between the crossbar 104 and the frame 2, and the sliding cooperation between the slider 101 and the slide bar, will push the two sets of connecting plates 102 to move towards each other. This will drive the equidistant actuating rods 103 on both sides to move towards each other to actuate the tea leaves inside the holding frame 3. At this time, the spring 106 will be compressed. When the roller 105 rolls away from the arc-shaped protrusion 108, the rebound effect of the spring 106 will drive the actuating rods 103 on both sides to automatically reset, thus actuating the tea leaves a second time. This effectively avoids the problem of the tea leaves being difficult to actuate, which would affect the withering effect. Finally, the bidirectional screw 201 is reversed to remove the holding frame 3 and pour out the withered tea leaves.
[0029] Example 2:
[0030] Based on Embodiment 1, the present invention is further improved in that: both sides of the bidirectional lead screw 201 are fixedly connected with guide rods 206 and the guide rods 206 are slidably connected to the moving block 202, which can play a certain guiding role in the horizontal movement of the moving block 202.
