Abstract
Description
Technical Field
[0001] This utility model belongs to the field of natural plant extraction technology, specifically a camphor leaf pulverizing device. Background Technology
[0002] In the field of natural plant ingredient extraction, camphor leaves, rich in volatile oils, flavonoids, and other active ingredients, are an important raw material. The quality of their pulverization pretreatment directly affects the subsequent extraction efficiency and component utilization. Camphor leaves have a dense fibrous structure and high toughness. If pulverization is insufficient, it will not only hinder the dissolution of effective ingredients but may also cause blockages in subsequent separation equipment, affecting the continuity of the production line.
[0003] Currently, the pulverization of camphor tree leaves mostly employs traditional mechanical pulverizing devices. These devices typically rely on a single pulverizing mechanism, such as blades or grinding rollers, to crush the material in a single pass. Their structural design prioritizes one-time processing efficiency while neglecting the need for multiple shearing and grinding operations required for fibrous materials. As downstream industries demand higher purity and yield of camphor tree leaf extracts, the shortcomings of traditional pulverizing devices in terms of particle size uniformity and thorough crushing are becoming increasingly apparent, making it difficult to meet the demands of refined production.
[0004] Patent application CN202421163684.2 discloses a ginkgo leaf pulverizing device. This device includes a lifting pulverizing assembly, which comprises a lifting support unit mounted above the pulverizing cylinder. A telescopic part can move in and out of the pulverizing cylinder along its central axis. The telescopic part of the lifting support unit is connected to a mounting frame for supporting the rotation drive. This pulverizing device ensures sufficient contact between the pulverizing assembly and the leaves through its movable pulverizing component, thereby improving the pulverizing effect. However, due to the high fiber content in the leaves, this structure results in significant stress during pulverization, which can easily cause jamming. The pulverized leaves also tend to clump together, causing blockages. Utility Model Content

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0027] Example:
[0028] A camphor leaf pulverizing device, such as Figure 1 as well as Figure 2As shown, it includes an installation mechanism, a crushing mechanism, and a transfer mechanism; the installation mechanism is used to install the crushing mechanism and the transfer mechanism, and the crushing mechanism is used to crush camphor leaves; the installation mechanism includes a mounting frame 1 and a mounting shell 3, the mounting shell 3 is connected to the mounting frame 1, the crushing mechanism is connected to the mounting frame 1 and located at the bottom of the mounting shell 3, and a feed inlet 2 is provided on one side of the mounting shell 3; as shown Figure 4 As shown, the material transfer mechanism includes a material collection trough 15, a material transfer auger 14, a material transfer pipe 16, a blower 8, a discharge pipe 4, a discharge pipe 5, and a return pipe 6. The material collection trough 15 is connected to the mounting frame 1 and located at the bottom of the crushing mechanism. The blower 8 is connected to one side of the mounting frame 1. The material transfer pipe 16 is used to connect the blower 8 and the material collection trough 15. One side of the material transfer auger 14 is located inside the material transfer pipe 16, and the other side is located inside the material collection trough 15. The discharge pipe 4 is connected to the blower 8. The discharge pipe 5 and the return pipe 6 are both connected to the discharge pipe 4. The return pipe 6 is also connected to the mounting shell 3. Gate valves are installed on both the return pipe 6 and the discharge pipe 5.
[0029] The crushing mechanism, the blower 8, and the auger 14 are all driven by the drive motor 7. The drive motor 7 is connected to the crushing mechanism via a belt, the crushing mechanism is connected to the auger 14 via a belt, and the crushing mechanism is also connected to the blower 8 via a belt.
[0030] Specifically, in use, first close the gate valve on the discharge pipe 5 and open the gate valve on the return pipe 6. Feed camphor tree leaves through the inlet 2 on the mounting shell 3. The crushing mechanism crushes the leaves, and the crushed leaves fall into the collection trough 15 at the bottom. The auger 14 conveys the crushed leaves through the transfer pipe 16 to the blower 8. The blower 8 blows the crushed leaves to the discharge pipe 4, and then through the discharge pipe 4 into the return pipe 6. Finally, the crushed leaves enter the mounting shell 3 through the return pipe 6, where the crushing mechanism crushes the leaves again. After multiple crushing processes, close the gate valve on the return pipe 6 and open the gate valve on the discharge pipe 5 to discharge the fully crushed camphor tree leaves. This design allows for multiple crushing processes of the camphor tree leaves, ensuring they are thoroughly crushed. The design of the material transfer auger 14, blower 8, discharge pipe 4, return pipe 6 and discharge pipe 5 realizes the effect of automatic material return and automatic material discharge, effectively improving work efficiency.
[0031] In a preferred embodiment, such as Figure 3As shown, the crushing mechanism includes a fixed shaft 12, fixed teeth 11, a rotating shaft 9, and rotating teeth 13. The fixed shaft 12 is fixedly connected to the mounting frame 1, and several fixed teeth 11 are fixedly connected to the fixed shaft 12. The rotating shaft 9 is rotatably connected to the mounting frame 1, and the rotating teeth 13 are connected to the rotating shaft 9 via a connecting member. The rotation path of the rotating teeth 13 passes through the gaps between the fixed teeth 11. Further optimized, the connecting member is a mounting plate 10, which is fixedly connected to the rotating shaft 9. The rotating teeth 13 are symmetrically arranged on both sides of the mounting plate 10 and fixedly connected to it. Further optimized, two fixed teeth 11 are grouped together, and multiple groups of fixed teeth 11 are evenly spaced on the fixed shaft 12; two rotating teeth 13 are grouped together, and multiple groups of rotating teeth 13 are evenly spaced on the rotating shaft 9. Further optimized, fixed shafts 12 are provided on both the front and rear sides of the mounting frame 1, and fixed teeth 11 are provided on the fixed shafts 12.
[0032] The relative movement of the rotating teeth 13 and the fixed teeth 11 breaks the camphor leaves through shearing and tearing, resulting in higher efficiency and more uniform crushing compared to single-rotation crushing. The rotating teeth 13 are symmetrically installed on both sides of the mounting plate 10, which counteracts centrifugal force during rotation, reduces equipment vibration, and improves operational stability. Both the fixed teeth 11 and the rotating teeth 13 are arranged in groups at even intervals, ensuring that the broken leaves are subjected to continuous shearing by multiple groups of teeth as they pass through the crushing area, avoiding local overload or insufficient crushing. The fixed teeth 11 and rotating teeth 13 on the front and rear fixed shafts 12 form symmetrical shearing with each other. When the rotating teeth 13 rotate, they engage with the fixed teeth 11 on both sides with a clearance, achieving bidirectional shearing, improving crushing efficiency, and resulting in more thorough fiber breakage of the broken leaves.
[0033] In a preferred embodiment, the bottom of the collecting trough 15 has a U-shaped structure. The U-shaped bottom fits snugly against the spiral-structured auger 14, allowing the auger to fully push the broken leaves during rotation, preventing material residue and improving conveying efficiency. Simultaneously, the U-shaped curved surface guides the broken leaves towards the center of the trough bottom, facilitating gripping by the auger blades, making it particularly suitable for fine, easily agglomerated camphor leaf fragments, reducing the risk of clogging.
[0034] In a preferred embodiment, the mounting frame 1 is a frame structure. The frame structure achieves high rigidity with less material through the combination of profiles, which can withstand the vibration and load during crushing and conveying, while reducing the weight of the equipment.
[0035] In a preferred embodiment, such as Figure 1 or Figure 2 As shown, the connection point between the return pipe 6 and the mounting shell 3 is located on the rear side of the top center of the mounting shell 3. The connection point being on the rear side forms a diagonal circulation of front feeding and rear return, reducing the impact of new and old materials, preventing blockage of the feed inlet 2, and ensuring a continuous and stable crushing process.
[0036] In a preferred embodiment, such as Figure 5As shown, the blower 8 includes a housing 19 and fan blades 18, with the fan blades 18 rotatably connected inside the housing 19. The housing 19 is provided with an air inlet 17 and an air outlet 20, wherein the air outlet 20 is located tangentially to the housing 19. The air inlet 17 is connected to the material transfer pipe 16, and the air outlet 20 is connected to the discharge pipe 4. Specifically, during operation, when the fan blades 18 rotate, the broken blades are thrown towards the edge of the housing 19 by centrifugal force. The tangentially oriented air outlet 20 allows the airflow and material to be discharged at maximum speed, reducing energy loss. Simultaneously, the tangential airflow forms a directional thrust, preventing broken blades from stagnating or flowing back inside the blower 8, ensuring that the broken blades smoothly enter the return pipe 6 or the discharge pipe 5 along the discharge pipe 4, reducing the risk of blockage.
[0037] In a preferred embodiment, such as Figure 1 or Figure 2 As shown, the feed inlet 2 on the mounting shell 3 is tilted upwards. The tilt angle is suitable for manual pouring or mechanical feeding, reducing material jamming and improving feeding efficiency. The upward tilt of the feed inlet 2 also avoids the splashing of broken leaves, and at the same time, uses gravity to guide the material to fall quickly into the crushing area, preventing accumulation and blockage at the inlet.
