Description

A flattening device for tea processing Technical Field

[0001] This utility model belongs to the field of tea processing technology, and in particular relates to a flattening device for tea processing. Background Technology

[0002] In current tea processing technology, tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Tea processing requires flattening and drying. This process involves flattening the fresh leaves to break the cell walls of the leaf tissue, accelerating moisture evaporation and drying, thus giving the tea leaves a softer and more delicate texture. The principle of tea flattening and drying is to break the tea leaves' cells through pressing, accelerating moisture evaporation and thus quickly drying the tea leaves; therefore, a flattening device is required.

[0003] Utility model patent CN214178933U discloses a tea flattening device, including a frame, a worktable on the frame, a workstation on the worktable, a pressure roller on one side of the workstation, a screen on the workstation, and a rake on the other side of the workstation. The beneficial effects of this utility model are: during tea flattening, it can evenly disperse and comb the tea leaves, ensuring uniform force during flattening, reducing damage to the tea leaves, improving tea quality, lowering production costs, and demonstrating good performance, thus facilitating widespread adoption.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The aforementioned patent describes a process where tea leaves are flattened using a rake. However, using a single roller to roll the tea leaves makes it difficult to adjust the distance between the roller and the tea leaves. If the pressure is too high, the tea leaves will become over-dried, affecting their quality. If the pressure is too low, the drying speed will be slow, also affecting the quality. In addition, manual feeding is required, resulting in high labor intensity and low efficiency. Summary of the Invention

[0006] This utility model provides a flattening device for tea processing, which aims to solve the problems mentioned in the background, such as the inconvenience of adjusting the distance between the roller and the tea leaves, the inconvenience of adjusting the pressure on the tea leaves, which affects the quality of the tea leaves, and the need for manual feeding, which results in high labor intensity and low efficiency.

[0039] Please refer to Figures 1-4. This utility model provides a technical solution: a flattening device for tea processing, including a conveying mechanism 1, which includes a support frame 11, a conveying frame 12 fixedly installed on the support frame 11, a support frame 121 fixedly installed on the conveying frame 12, and a rolling mechanism 2, which includes a "U"-shaped fixed frame 21, multiple fixed frames 21 fixedly installed on the conveying frame 12, and grooves 211 are provided on both outer walls of the fixed frame 21. Pneumatic push rods 22 are fixedly installed on both outer walls of the fixed frame 21. A slider 221 that is slidably connected to the groove 211 is fixedly installed at the telescopic end of the pneumatic push rod 22. Flattening rollers 23 are rotatably installed on the two sliders 221. A reduction motor 231 is fixedly installed on the sliders 221, and the reduction motor 231 is connected to the flattening rollers 23.

[0040] Among them, the pneumatic push rod 22 drives the slider 221 to move longitudinally, which in turn drives the flattening roller 23 to move longitudinally. The height of the flattening roller 23 is adjusted to facilitate the adjustment of the pressure applied by the flattening roller 23, thereby flattening different types of tea. The reduction motor 231 drives the flattening roller 23 to rotate and flatten the tea. The height of the multiple flattening rollers 23 is arranged from high to low. The farther away from the tea, the lower the height of the flattening roller 23.

[0041] A conveying screw 13 is rotatably mounted on the conveying frame 12. A sliding nut 131 is threadedly connected to the conveying screw 13. A drive motor 14 is fixedly mounted on the conveying frame 12. The drive motor 14 is connected to the conveying screw 13.

[0042] Among them, the drive motor 14 drives the conveying screw 13 to rotate, thereby using the rotation of the conveying screw 13 to drive the sliding screw nut 131 to move laterally and adjust the lateral position of the sliding screw nut 131.

[0043] A movable platform 15 is fixedly installed on the sliding nut 131. The side wall of the movable platform 15 is rotatably connected to the scraper 16 via a rotating shaft. A connecting spring 161 is fixedly connected to the outer wall of the scraper 16. One end of the connecting spring 161 is fixedly connected to the scraper 16, and the other end is fixedly connected to the movable platform 15.

[0044] Furthermore, the mobile platform 15 moves laterally along the sliding nut 131, and the mobile platform 15 can move laterally repeatedly on the conveyor frame 12. When the connecting scraper 16 contacts the flattening roller 23, the scraper 16 scrapes off the residual tea leaves on the outer wall of the flattening roller 23, and the connecting spring 161 pulls the scraper 16 through its own elasticity, so that the scraper 16 contacts the outer wall of the flattening roller 23, which facilitates the cleaning of the flattening roller 23.

[0045] The feeding mechanism 3 is used for feeding materials. The feeding mechanism 3 is fixedly installed on the support frame 121. The feeding mechanism 3 includes a feeding hopper 31, which is fixedly installed on the support frame 121. A conical discharge box 32 is installed at the lower end of the feeding hopper 31. The discharge box 32 is connected to the feeding hopper 31. A feeding pipe 321 is installed at the lower end of the discharge box 32. A spiral feeding shaft 33 is rotatably installed inside the discharge box 32. Spiral fan blades 331 connected end to end are provided on the outer wall of the spiral feeding shaft 33. A second drive motor 34 is fixedly installed on the bottom wall of the discharge box 32. The second drive motor 34 is connected to the spiral feeding shaft 33.

[0046] Specifically, tea leaves are stored in the hopper 31 and fall into the discharge box 32. The drive motor 34 drives the spiral feeding shaft 33 to rotate, thereby receiving the tea leaves through the spiral fan blades 331 connected end to end. The spiral fan blades 331 are then used to transport the tea leaves, causing them to fall and be discharged from the discharge pipe 321 onto the moving platform 15, thus achieving quantitative feeding.

[0047] Multiple feet 111 are fixedly installed at the lower end of the support frame 11, and the multiple feet 111 are set at the four corners of the support frame 11.

[0048] It should be noted that matching bolts can be passed through the pads 111 to fix multiple pads 111 to the ground, thereby improving the stability of the support frame 11 and the device during operation.

[0049] The working principle and usage process of this utility model are as follows: Please refer to Figures 1-4. Tea leaves are stored in the hopper 31 and fall into the discharge box 32. The drive motor 34 drives the spiral feeding shaft 33 to rotate, thereby receiving the tea leaves through the spiral fan blades 331 connected end to end. The spiral fan blades 331 then transport the tea leaves, causing them to fall and be discharged from the discharge pipe 321 onto the moving platform 15. The drive motor 14 drives the conveying screw 13 to rotate, thereby causing the sliding screw nut 131 to move laterally. The moving platform 15 follows the sliding screw nut. The mother 131 moves laterally, and the moving platform 15 can move laterally repeatedly on the conveyor frame 12, thereby repeatedly receiving tea leaves and spreading them flat on the moving platform 15. When the moving platform 15 moves, it passes under the flattening roller 23. The pneumatic push rod 22 drives the slider 221 to move longitudinally, which in turn drives the flattening roller 23 to move longitudinally. Adjusting the height of the flattening roller 23 makes it easier to adjust the pressure applied by the flattening roller 23, thereby flattening different types of tea leaves. The reduction motor 231 drives the flattening roller 23 to rotate, making the flattening efficiency of tea leaves higher.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
