Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a toothed cutter for tea processing. Background Technology

[0002] In the deep processing of tea, such as tea bags and tea powder, it is usually necessary to break the tea leaves into small, uniform particles in order to increase the dissolution area and improve extraction efficiency. A toothed crusher is a key piece of equipment for this process, using a high-speed rotating toothed disc to cut and pulverize the tea leaves.

[0003] Currently, common toothed crushers typically have a simple discharge chute directly below the outlet. Operators place collection containers (such as woven bags or collection boxes) under the chute to collect the material. This collection method has significant drawbacks: First, when a collection container is full, the machine must be stopped to replace it; otherwise, the tea leaves will scatter on the ground, causing production interruptions and severely impacting processing efficiency, which is extremely inconvenient, especially for scenarios with high requirements for continuous production. Second, the particle size of the tea leaves processed by the toothed crusher may be uneven, with some large, substandard tea leaves mixed in with the finished product and discharged along with it. These large particles affect the quality, uniformity, and appearance of the final product.

[0004] Therefore, we propose a toothed cutter for tea processing. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a toothed cutting machine for tea processing. Through reversible conveying and symmetrically arranged vibration filtering units, it enables continuous tea processing and online screening without stopping the machine, thereby improving production efficiency while effectively ensuring the quality of the finished tea and effectively solving the problems in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a toothed cutting machine for tea processing, including a toothed crusher, wherein a flat belt conveyor is provided below the discharge chute of the toothed crusher, and the discharge end of the discharge chute extends to the upper part of the middle of the conveyor belt of the flat belt conveyor. Both ends of the flat belt conveyor are provided with a feeding filter structure. The feeding filter structure includes a rectangular frame, a vibrating motor, a fixed block, a support column, a base block, a helical spring, a guide rod, a screen plate, an annular fixed frame, a handle, an annular support magnet, a collection trough, and a guide ring. Support plates are fixedly installed on the front and rear sides of the upper part of the frame of the flat belt conveyor, and a guide plate is fixedly installed on the side of the support plate near the conveyor belt of the flat belt conveyor.

[0007] Preferably, the rectangular frame is located below the discharge port of the flat belt conveyor. In one set of the discharge filtering structure, there are two sets of the fixing block, support column, base block, helical spring, guide rod and guide ring. The two sets of fixing blocks are fixed in the middle of the outer surface at both ends of the rectangular frame. In one set of the discharge filtering structure, there are four sets of vibration motors. The four sets of vibration motors are fixed at the front and rear ends of the outer surface on both sides of the rectangular frame. The annular support magnet is fixed in the upper part of the inner cavity of the rectangular frame.

[0008] Preferably, the annular fixing frame is disposed within the rectangular frame, the screen plate is fixed to its inner wall, and the handles are fixed to both ends of its upper outer surface; the annular fixing frame is magnetically attached to the annular support magnet.

[0009] Preferably, the support column is fixed to the upper outer surface of the base block, the storage groove is opened on the upper outer surface of the support column, the guide ring is fixed to the upper part of the storage groove, the guide rod passes through the guide ring, and the upper outer surface of the guide rod is fixedly connected to the lower outer surface of the fixing block.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a toothed cutter for tea processing, which has the following beneficial effects: 1. This toothed tea processing machine, by setting up a flat belt conveyor and symmetrically distributed feeding and filtering structures, achieves uninterrupted and continuous collection of tea leaves. Specifically, when the collection container below the feeding and filtering structure at one end of the flat belt conveyor is about to be full, the flat belt conveyor can be started in reverse to transport the material to the other end for collection, thus completing the replacement of the collection container without stopping the machine. This effectively solves the problem of low production efficiency caused by machine stoppage for material replacement in the prior art, and improves the overall efficiency of tea processing.

[0013] 2. This toothed tea processing machine integrates a vibrating filter structure below the feed inlet, enabling real-time online screening of crushed tea leaves. The screen can intercept large tea particles that do not meet specifications, while qualified small particles fall into the collection container. The vibrating motor effectively prevents screen blockage, improves screening efficiency and effect, and overcomes the defect of existing equipment where large particles are mixed in the finished product, affecting quality.

[0014] 3. This toothed cutter for tea processing uses a screen plate that is fixed by magnetic adsorption between a ring-shaped fixing frame and a ring-shaped supporting magnet, making the disassembly, cleaning, and replacement of the screen extremely simple and quick; it is convenient to regularly clean large particles of debris remaining on the screen or replace the screen with a different mesh size to adapt to different process requirements.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a toothed cutting machine for tea processing. The toothed cutting machine includes a conventional toothed crusher 1, with a discharge chute 2 at its front end. The end of the discharge chute 2 away from the main body of the toothed crusher 1 extends downwards and reaches the middle of the upper conveyor belt surface of a flat belt conveyor 3. The conveyor belt of the flat belt conveyor 3 runs in a reversible direction, meaning it can be controlled to rotate forward or backward (as per existing technology) via a control system (not shown in the figure).

[0023] Support plates 5 are fixedly installed on the front and rear sides of the upper part of the frame of the flat belt conveyor 3. A guide plate 6 is fixedly installed on the side of the support plate 5 near the conveyor belt of the flat belt conveyor 3. The guide plate 6 is arranged along both sides of the conveyor belt to guide the tea leaves discharged from the discharge chute 2.

[0024] At the lower part of both ends of the flat belt conveyor 3, two sets of identical feeding filter structures 4 are symmetrically arranged. The feeding filter structure 4 mainly includes a rectangular frame 7, a vibrating motor 8, a fixing block 9, a support column 10, a base block 11, a helical spring 12, a guide rod 13, a screen plate 14, an annular fixing frame 15, a handle 16, an annular support magnet 17, a collection trough 18, and a guide ring 19.

[0025] The rectangular frame 7 is located below the end of the flat belt conveyor 3, directly opposite the material discharge area at the end of the conveyor belt, and is used to receive tea leaves falling from the flat belt conveyor 3. In a set of material discharge and filtration structures 4, there are two sets of fixing blocks 9, support columns 10, base blocks 11, helical springs 12, guide rods 13, and guide rings 19, symmetrically arranged at both ends of the rectangular frame 7. The two sets of fixing blocks 9 are fixed to the middle of the outer surface at both ends of the rectangular frame 7. The lower end of the support column 10 is fixed to the upper surface of the base block 11, which is fixed to the ground by anchor bolts or other means, providing stable support for the entire material discharge and filtration structure 4. A cylindrical receiving groove 18 is opened on the upper outer surface of the support column 10. The guide ring 19 is fixedly installed at the upper opening of the receiving groove 18. The lower part of the guide rod 13 passes through the guide ring 19 and can move up and down within the receiving groove 18, while the upper end of the guide rod 13 is fixedly connected to the lower end face of the fixing block 9 on the rectangular frame 7. The outer wall of the guide rod 13 and the inner wall of the guide ring 19 are slidably connected with clearance fit. The helical spring 12 is movably sleeved on the outer periphery of the upper part of the guide rod 13, and its upper and lower ends are respectively fixed to the lower surface of the fixing block 9 and the upper surface of the support column 10, thus forming an elastic vibration damping system, enabling the rectangular frame 7 to elastically vibrate relative to the base block 11.

[0026] In a set of feeding and filtering structures 4, there are four sets of vibrating motors 8, which are fixedly installed at the front and rear ends of the outer surfaces on both sides of the rectangular frame 7. When the vibrating motors 8 are working, they drive the rectangular frame 7 and its internal components to generate high-frequency micro-amplitude vibrations.

[0027] A ring-shaped support magnet 17 is fixed to the upper part of the inner cavity of the rectangular frame 7. The screen plate 14 is placed inside the rectangular frame 7 via a ring-shaped fixing frame 15 on its outer edge. The ring-shaped fixing frame 15 is made of a material that can be attracted by magnets (such as low carbon steel), and it is fixed to the ring-shaped support magnet 17 by magnetic attraction, thereby realizing the quick installation and fixation of the screen plate 14 inside the rectangular frame 7. Handles 16 are fixed at both ends of the upper outer surface of the ring-shaped fixing frame 15, which facilitates the operator to lift or lower the screen plate 14 assembly for cleaning or replacement.

[0028] Working principle: After being crushed by the toothed crusher 1, the tea leaves fall directly into the middle of the upper belt surface of the flat belt conveyor 3 through its discharge chute 2. Initially, the flat belt conveyor 3 runs in the forward direction (e.g., conveying to the left), and the tea leaves move to the left with the conveyor belt and fall into the left-side discharge filter structure 4. The tea leaves fall into the left-side rectangular frame 7 and onto the screen plate 14. At this time, the vibration motor 8 of the left-side discharge filter structure 4 is started, and the vibration is transmitted to the screen plate 14 through the rectangular frame 7. Qualified fine tea leaves fall through the mesh of the screen plate 14 under the action of vibration and enter the collection container placed below it; while large tea leaves that do not meet the particle size requirements are intercepted on the screen plate 14. The elastic support system effectively buffers and maintains the vibration process, preventing the vibration from being directly transmitted to the ground.

[0029] When the left-side collection container is nearly full, there is no need to stop the toothed crusher 1. Simply switch the running direction of the flat belt conveyor 3 via the control system, making it run in reverse (to the right). The tea leaves falling from the discharge chute 2 are then conveyed to the right and fall into the right-side discharge filter structure 4 for the same screening and collection process. At this time, the operator can safely replace the full left-side collection container and hold the handle 16 to lift the left-side screen plate 14 along with the annular fixing frame 15 to clean up the large particles accumulated on it. When the right-side collection container is nearly full, the conveying direction can be switched back to the left, and so on, achieving uninterrupted continuous production and improving production efficiency and product quality.
