Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a multi-layer impurity screening device for tea production. Background Technology

[0002] Tea is one of the world's three major beverages, and is also known as "the night-reliever". Tea leaves are oblong or elliptical in shape, with a wedge-shaped base and serrated edges. Drinking tea has the effects of refreshing the mind, anti-oxidation, anti-aging, and beautifying the skin.

[0003] As a traditional beverage, tea now requires screening devices to separate the debris and dust generated during the frying process after processing in order to improve the quality of the finished tea product.

[0004] Impurity screening is a crucial step in tea processing, and existing screening devices generally suffer from the following problems:

[0005] Insufficient stirring effect: Traditional stirring components are mostly rigid structures, which can easily cause tea leaves to clump together or break due to hard contact with the sieve plate during stirring. In addition, the stirring is uneven, which affects the screening efficiency.

[0006] Limited screening precision: Single-layer screening structure can only separate materials of a single particle size, which cannot meet the multi-layer grading requirements for different impurity particles in tea processing. Multiple screenings are often required, which is time-consuming and labor-intensive.

[0007] Poor structural stability: Some devices have weak support structures, resulting in significant vibration during the screening process, which can cause screen plate displacement or component loosening, affecting screening accuracy and equipment lifespan;

[0008] Inconvenient material feeding: After material screening, collection relies heavily on manual labor, resulting in low automation and increased production costs.

[0009] To address the aforementioned problems, this utility model provides a multi-layer impurity screening device for tea processing. By setting up a multi-layer screening disc, a flexible stirring component, and a stable support structure, it achieves efficient separation of tea leaves and impurities, material protection, and automated material feeding. It solves the defects of existing technologies, such as stirring damage to materials, insufficient screening accuracy, and unstable structure, significantly improving the tea screening quality and production efficiency, and meeting the actual needs of the tea processing industry. Utility Model Content

[0010] The purpose of this invention is to provide a multi-layer impurity screening device for tea processing, so as to solve the problems mentioned in the background art.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0012] A multi-layer impurity screening device for tea processing includes a screening disc one, a screening disc two, and a guide hopper. The screening disc one, screening disc two, and guide hopper are arranged sequentially from top to bottom. A drive motor is fixedly connected to the bottom surface of the guide hopper. A rotating rod is fixedly connected to the output end of the drive motor. The top end of the rotating rod moves through the screening disc two and the screening disc one in sequence. A stirring assembly is provided inside the screening disc one.

[0013] The stirring assembly includes a positioning sleeve, which is fixedly sleeved on the outer wall of the rotating rod near the top end, and a stirring frame is fixedly connected to the outer wall of the positioning sleeve.

[0014] A further improvement of this utility model is that: a crossbar is rotatably connected to the inner wall of the stirring frame, and a stirring plate is fixedly connected to the outer wall of the crossbar.

[0015] A further improvement of this utility model is that a torsion spring is fixedly connected to the center of one end of the stirring plate.

[0016] A further improvement of this utility model is that one end of the stirring frame is movably connected to the inner wall of the screening disc.

[0017] A further improvement of the present invention is that: a reinforcing side rod is fixedly connected to the outer wall of the screening disc, and a supporting base is fixedly connected to the bottom surface of the guide hopper.

[0018] A further improvement of this utility model is that the bottom end of the reinforcing side rod is fixedly connected to the upper surface of the supporting base frame.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. This utility model provides a multi-layer screening device for impurities in tea processing. The multi-layer screening structure improves efficiency: screening disc one and screening disc two are arranged sequentially from top to bottom, and the sieve aperture gradually decreases, realizing the layered screening of tea and impurities. It can accurately separate materials of different particle sizes, improve screening accuracy and efficiency, and meet the strict requirements for impurity removal in tea processing.

[0021] 2. This utility model provides a multi-layer impurity screening device for tea processing. The flexible stirring component protects the material: the stirring plate is connected to the crossbar by a torsion spring and can rotate around the crossbar. When it contacts the bottom of the screening plate or clumps of material, the elastic deformation of the torsion spring causes the stirring plate to adjust its angle adaptively, avoiding hard squeezing or damage to the tea, protecting the integrity of the tea, and effectively dispersing clumps and improving the uniformity of stirring.

[0022] 3. This utility model provides a multi-layer impurity screening device for tea processing, with a linkage drive that simplifies operation: the drive motor synchronously drives the stirring frame to rotate via a rotating rod, eliminating the need for an additional power source, simplifying the device structure, and reducing energy consumption. One end of the stirring frame is movably connected to the inner wall of the screening disc, ensuring that the stirring range covers the entire area of ​​the screening disc, avoiding dead corners, and improving the stirring effect.

[0023] 4. This utility model provides a multi-layer impurity screening device for tea processing, with a stable structure to ensure operation: the side rods connect the screening disc to the supporting base, enhancing the overall rigidity of the device, reducing vibration and shaking during the screening process, ensuring long-term stable operation of the equipment, and extending its service life.

[0024] 5. This utility model provides a multi-layer impurity screening device for tea production. The material guiding design optimizes the process: the inclined hopper is placed at an angle, and the screened material slides down automatically by gravity, reducing manual intervention, optimizing the production process, and improving the degree of automation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a multi-layer impurity screening device for tea processing, including a screening disc 1, a screening disc 2, and a guide hopper 3. The screening disc 1, the screening disc 2, and the guide hopper 3 are arranged in order from top to bottom. A drive motor 8 is fixedly connected to the bottom surface of the guide hopper 3. A rotating rod 4 is fixedly connected to the output end of the drive motor 8. The top end of the rotating rod 4 moves through the screening disc 2 and the screening disc 1 in sequence. A stirring assembly 5 is provided inside the screening disc 1.

[0034] The stirring assembly 5 includes a positioning sleeve 12, which is fixedly sleeved on the outer wall of the rotating rod 4 near the top end, and a stirring frame 9 is fixedly connected to the outer wall of the positioning sleeve 12.

[0035] A crossbar 11 is rotatably connected to the inner wall of the stirring frame 9, and a stirring plate 10 is fixedly connected to the outer wall of the crossbar 11.

[0036] A torsion spring 13 is fixedly connected to the center of one end of the stirring plate 10.

[0037] Example 2

[0038] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, one end of the stirring frame 9 is movably connected to the inner wall of the screening disc 1.

[0039] The outer wall of the screening disc 1 is fixedly connected with a reinforcing side rod 7, and the bottom surface of the guide hopper 3 is fixedly connected with a supporting base frame 6.

[0040] The bottom end of the reinforcing side rod 7 is fixedly connected to the upper surface of the supporting base frame 6.

[0041] The working principle of this multi-layer impurity screening device for tea production will be explained in detail below.

[0042] like Figure 1-4 As shown, when using this multi-layer impurity screening device for tea processing, the drive motor 8 is fixed to the bottom surface of the guide hopper 3, and its output end drives the rotating rod 4 to rotate. The top of the rotating rod 4 passes through the second screening plate 2 and the first screening plate 1 in sequence. The positioning sleeve 12 located inside the first screening plate 1 is fixedly sleeved on the outer wall of the rotating rod 4 and rotates synchronously with the rotating rod 4, thereby driving the stirring frame 9 on the outer wall of the positioning sleeve 12 to rotate around the axis of the rotating rod 4. The stirring plate 10 is fixedly connected to the crossbar 11 on the inner wall of the stirring frame 9. In the initial state, it is arranged parallel to the bottom of the inner wall of the first screening plate 1. When the stirring frame 9 rotates, the stirring plate 10 moves in a circular motion with the stirring frame 9 to stir the tea and impurities in the first screening plate 1.

[0043] Because one end of the stirring plate 10 is connected to the crossbar 11 via a torsion spring 13, when the stirring plate 10 contacts the bottom of the screening tray 1 or encounters clumps of tea leaves, the torsion spring 13 undergoes elastic deformation, allowing the stirring plate 10 to rotate around the crossbar 11, thus preventing hard collisions that could damage the tea leaves or cause the stirring components to jam. During the stirring process, the tea leaves and impurities are evenly dispersed under the push of the stirring plate 10. Smaller impurities or tea leaves fall through the sieve holes of the screening tray 1 into the lower screening tray 2, while larger particles remain in the screening tray 1. The sieve holes of the screening tray 2 are smaller than those of the screening tray 1, achieving a second layer of screening. Materials that meet the sieve size requirements fall into the guide hopper 3. The guide hopper 3 is placed at an angle, facilitating the material to slide down the slope to subsequent processing steps.

[0044] The support frame 6 is fixed to the bottom surface of the guide hopper 3, and the reinforcing side rod 7 connects the outer wall of the screening disc 1 to the support frame 6 to ensure the overall stability of the device and avoid component displacement caused by vibration during the screening process.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
