Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a withering and spreading device for tea processing. Background Technology

[0002] Withering is an important step in tea processing. Fresh leaves are spread out evenly to allow them to lose an appropriate amount of moisture, making the leaves soft. During the withering process, the tea leaves are usually turned over, as this helps to promote the even distribution of moisture, ensuring that all parts of the tea leaf wither to the same degree. It also accelerates the release of grassy aroma and promotes the formation of aromatic substances.

[0003] However, in some tea withering processes, manual turning of the tea leaves is relied upon. However, manual turning is inefficient and cannot meet the needs of large-scale production. Moreover, the force and frequency of operation vary from person to person, which can easily lead to uneven withering of tea leaves and affect the quality of tea. At the same time, manual turning increases production costs and labor intensity, and can no longer meet the development needs of the modern tea processing industry.

[0004] In order to meet the needs of large-scale tea production and reduce labor costs and the labor intensity of turning tea leaves, this application proposes a withering and spreading device for tea processing. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1 , Figure 3 as well as Figure 6A withering and spreading device for tea processing includes a workbench 1, a conveyor 2 fixedly connected to the top of the workbench 1, slots 7 on both the front and rear sides and the left and right sides of the top of the workbench 1 on the conveyor 2, baffles 3 on the inner walls of the slots 7 on both the front and rear sides, slots 25 on the opposite sides of the baffles 3, inserts 16 on the inner walls of the slots 25, partitions 4 fixedly connected to the opposite ends of the inserts 16 on both the left and right sides, a sliding groove 19 on the rear end of the front partition 4, a trajectory groove 18 on the inner wall of the rear partition 4, a transmission rod 13 on the right side of the inner wall of the trajectory groove 18, a rotating roller 15 slidably connected to the front side of the outer wall of the transmission rod 13, a spring 20 fixedly connected to the front end of the transmission rod 13, the other end of the spring 20 fixedly connected to the inner wall of the rotating roller 15, buckets 14 fixedly connected to all four sides of the outer wall of the rotating roller 15, a movable block 21 fixedly connected to the front end of the rotating roller 15, and the outer wall of the movable block 21 located on the right side of the inner wall of the sliding groove 19.

[0027] To further explain, first, the device is placed in the existing withering room. Then, the staff inserts the bottom of the baffle 3 into the slot 7 in sequence, and the partition 4 with the track groove 18 is placed on the side near the motor 8, while the partition 4 with the sliding groove 19 is inserted on the other side. Then, the insert 16 is inserted into the slot 25 to complete the assembly of the baffle 3 and the partition 4, which creates a blocking effect on the surface of the conveyor 2. Then, the conveyor 2 is started. At this time, the staff stands on the right side of the workbench 1 and pours the tea leaves onto the top of the conveyor 2. As the surface of the conveyor 2 is circulated and rolled, the tea leaves are spread evenly on the top of the conveyor 2 until the top of the conveyor 2 is within the area formed by the baffle 3 and the partition 4. After the tea leaves are spread, the operation of the conveyor 2 is stopped. Then, under the operation of the equipment in the withering room, the ambient temperature rises, the moisture in the tea leaves evaporates, and the tea leaves wither.

[0028] The multiple buckets 14 fixed on the outer wall of the rotating roller 15 are arranged in pairs opposite each other, and the opening directions of the two opposite buckets 14 are opposite. No matter whether the rotating roller 15 rotates forward or backward, the buckets 14 can scoop up the tea leaves and put them into the inner cavity. After the opening of the bucket 14 is facing down, the tea leaves are poured onto the top of the conveyor table 2.

[0029] The electric drive components and drive equipment in the conveyor 2 of this device have been debugged and operated by an external controller, and run according to the set programming logic instructions.

[0030] Example 2

[0031] Please see Figure 2 , Figures 4-5Further, based on Embodiment 1, a slide groove is provided at the rear end of the workbench 1. A motor 8 is fixedly connected to the right end of the inner wall of the slide groove. A threaded rod 10 is fixedly connected to the drive end of the motor 8. The left end of the threaded rod 10 is rotatably connected to the inner wall of the slide groove. A displacement block 9 is threadedly connected to the outer wall of the threaded rod 10. The outer wall of the displacement block 9 is slidably connected to the inner wall of the slide groove. A bending plate 11 is fixedly connected to the rear end of the displacement block 9. A motor 12 is fixedly connected to the middle of the rear end of the bending plate 11. The drive end of the motor 12 passes through the front of the bending plate 11 and is fixedly connected to... There is a first rotating wheel 23, and a second rotating wheel 26 is rotatably connected to the upper front side of the outer wall of the bending plate 11. The front end of the second rotating wheel 26 has a limiting groove 24. The top of the outer diameter of the second rotating wheel 26 is meshed with a synchronous belt 22. The bottom of the inner diameter of the synchronous belt 22 is meshed with the bottom of the outer diameter of the first rotating wheel 23. The rear end of the transmission rod 13 is fixedly connected to a shaped block 17. The shape of the outer wall of the shaped block 17 matches the shape of the inner wall of the limiting groove 24. A receiving box 5 is provided on the inner wall of the left end of the workbench 1. A dropping port 6 is provided on the top of the workbench 1 above the receiving box 5.

[0032] To further explain, the transmission rod 13 is inserted through the opening of the track groove 18, and the movable block 21 is inserted through the opening of the sliding groove 19. Simultaneously, the transmission rod 13 is pushed towards the rotating roller 15, causing one end to compress the spring 20. Then, when the irregularly shaped block 17 is positioned on one side of the limiting groove 24, the transmission rod 13 is released, and under the elastic action of the spring 20, the transmission rod 13 returns to its original position, causing the irregularly shaped block 17 to insert into the limiting groove 24, thus limiting the transmission rod 13. Then, the motor 12 is started, causing... Its drive end drives the first rotating wheel 23 to rotate, and through the power transmission of the synchronous belt 22, the second rotating wheel 26 rotates. Then, through the engagement of the limiting groove 24 and the irregular block 17, the transmission rod 13 and the rotating roller 15 rotate. During the rotation of the rotating roller 15, the shovels 14 located on the upper and lower sides of the outer wall of the rotating roller 15 will scoop up the tea leaves. After rotating once, the tea leaves are poured back onto the top of the conveyor table 2, thus forming a turning of the tea leaves, promoting contact between the various parts of the tea leaves and the air, and maintaining the uniformity of moisture dissipation.

[0033] At the same time, motor 8 is started, causing its drive end to drive the threaded rod 10 to rotate, causing the displacement block 9 to slide in the inner wall of the slide groove at the rear end of the worktable 1, and driving the bending plate 11 to move. This causes the outer wall of the transmission rod 13 to slide in the track groove 18, the movable block 21 to slide in the sliding groove 19, and the rotating roller 15 to move accordingly. Motor 12 continues to run, thereby turning over the tea leaves at various points on the top of the conveyor 2. Then, when the rotating roller 15 moves to the leftmost side of the top of the conveyor 2, the drive ends of motor 8 and motor 12 are reversed. At this time, the buckets 14, which were originally located on the left and right sides of the outer wall of the rotating roller 15, will continue to turn over the tea leaves until the withering of the tea leaves is completed.

[0034] Then, start motor 8 again to make the bending plate 11 slide back to its original position. Then, press the transmission rod 13 again to make the irregular block 17 disengage from the limiting groove 24. Then, lift the transmission rod 13 upward, and move the roller 15 and bucket 14 away from the two side partitions 4. Then, pull the partition 4 out from between the baffles 3 and pull the baffles 3 out from the top of the worktable 1. Then, start the conveyor 2 and move its top towards the discharge port 6. This will cause the tea leaves on the top of the conveyor 2 to fall from the discharge port 6 into the collection box 5 for collection. Then, pull the collection box 5 out from the worktable 1.

[0035] Working principle: First, place the baffle 3 in the existing withering room. Then, insert the bottom of the baffle 3 into the slot 7 on the worktable 1. Install the partition 4 with the track groove 18 on the side near the motor 8, and place the partition 4 with the sliding groove 19 on the other side. Then, insert the insert 16 into the slot 25. This completes the assembly of the baffle 3 and partition 4, which can form a barrier on the top of the conveyor table 2. Next, insert the transmission rod 13 through the opening of the track groove 18 and push it into the roller 15, while compressing the spring 20 at one end. At the same time, insert the movable block 21 through the opening of the sliding groove 19. When the shaped block 17 is placed on one side of the limiting groove 24, the transmission rod 13 is released. Under the elastic action of the spring 20, the transmission rod 13 is reset, and the shaped block 17 is inserted into the limiting groove 24 to limit the transmission rod 13. Then, the conveyor 2 is started. The worker stands on the right side of the workbench 1 and pours the tea leaves onto the top of the conveyor 2. As the conveyor 2 rolls in a cycle, the tea leaves are gradually spread out on it. When the top of the conveyor 2 is covered with tea leaves within the area formed by the baffle 3 and the partition 4, the conveyor 2 is stopped. At this time, the equipment in the withering room is started to raise the ambient temperature, so that the moisture in the tea leaves evaporates and the withering process begins.

[0036] During tea withering, motor 12 is started, and its drive end drives the first wheel 23 to rotate. Power is transmitted through the synchronous belt 22, causing the second wheel 26 to rotate. With the help of the engagement of the limiting groove 24 and the irregular block 17, the transmission rod 13 and the rotating roller 15 are driven to rotate. During the rotation of the rotating roller 15, the shovels 14 on the upper and lower sides of the outer wall scoop up the tea leaves, rotate them once, and then pour them back to the top of the conveyor table 2. This achieves the turning of the tea leaves, promotes full contact between all parts of the tea leaves and the air, and ensures that the moisture is evenly distributed. At the same time, motor 8 is started, and its drive end drives the threaded rod 10 to rotate, causing the displacement block 9 to slide on the inner wall of the slide groove at the rear end of the worktable 1, which drives the bending plate 11 to move. This causes the outer wall of the transmission rod 13 to slide in the track groove 18, and the movable block 21 to slide in the sliding groove 19. The rotating roller 15 moves accordingly, while the second motor 12 continues to run, causing the bucket 14 to turn over the tea leaves at various points on the top of the conveyor table 2. When the rotating roller 15 moves to the leftmost side of the top of the conveyor table 2, the drive ends of the first motor 8 and the second motor 12 are reversed. The buckets 14 on the other two sides continue to turn over the tea leaves until the withering work is completed. After the withering work is completed, the bending plate 11 is reset, the transmission rod 13 is pressed to make the irregular block 17 disengage from the limiting groove 24, and then the transmission rod 13 is lifted upward, which moves the rotating roller 15 and the bucket 14 away from the space between the two side partitions 4. Then the partitions 4 are pulled out, the baffle 3 is pulled out, and the conveyor table 2 is started again, so that its top moves towards the discharge port 6. The tea leaves fall from the discharge port 6 into the receiving box 5. Finally, the receiving box 5 is pulled out from the workbench 1 to complete the entire workflow.
