Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, specifically referring to a visual, dust-free, quick-disassembly crusher. Background Technology

[0002] In the field of cosmetic manufacturing, pulverizers are core equipment for the pretreatment of powder raw materials, undertaking the crucial task of processing various initial raw materials to a suitable particle size distribution. Their applications are wide-ranging, including primary crushing of mineral blocks such as talc and mica to obtain coarse particles; and deagglomerating and finely classifying dried and agglomerated plant extracts (such as green tea extract and centella asiatica extract) or aggregated color powders to prepare powder compositions suitable for products such as foundation, eyeshadow, face masks, and serums. During the pulverization process, these materials not only generate coarse particles but also produce a large amount of fine powder and even micron-sized dust, posing unique challenges to equipment efficiency and the production environment. Existing pulverizer technology struggles to meet the complex demands of the modern cosmetic industry for graded pulverization, clean production, and efficient maintenance, specifically in the following three aspects: Firstly, disassembly and maintenance are cumbersome, posing a high risk of cross-contamination and incurring significant downtime costs. Existing pulverizers often use multiple sets of bolts to rigidly connect the pulverizing chamber to the frame. When cleaning residual materials of different particle sizes, replacing screens, or overhauling the pulverizing blade assembly, operators must use specialized tools for tedious disassembly. This process is not only time-consuming and labor-intensive, affecting production continuity, but more seriously, frequent disassembly and assembly can lead to wear on connecting parts and failure of sealing surfaces. Consequently, when processing mixed coarse and fine powders, fine powder can easily escape from the failed seals, causing cross-contamination between different batches and color grades of raw materials, posing a serious threat to product quality consistency.

[0003] Secondly, the grading efficiency is low, dust dispersion is serious, and the recovery of high-value fine powder is difficult. Traditional pulverizers often lack effective internal grading and real-time dust collection mechanisms. During the pulverization process, the coarse and fine materials are mixed and tumble together under the turbulence of airflow inside the machine, making it difficult to separate and discharge the fine powder in time. Not only is it prone to over-pulverization, but it will also settle with the coarse powder or escape through unreasonable suction methods. For cosmetic fine powder raw materials with light density and easy dispersion, the design of a single dust inlet far away from the pulverization area cannot achieve efficient capture, resulting in the loss of a large amount of high-value fine powder with dust dispersion, increasing production costs and polluting the cleanroom environment.

[0004] Thirdly, the operational status is not visible, making it difficult to control the degree of crushing and the grading effect. Most existing crushers have fully enclosed metal crushing chambers, preventing operators from observing the crushing progress, particle size distribution, and grading status of the materials inside in real time. For production processes that require simultaneous control of the ratio of coarse to fine powder output, the only way to assess the effect is through frequent shutdowns to open the lid for sampling and sieving, making it impossible to adjust crushing parameters in a timely manner or detect grading anomalies. This passive approach easily leads to uneven particle size distribution in the product, excessive fine powder mixed in with coarse powder, or low fine powder collection efficiency, severely affecting the application performance and quality stability of the final product. Utility Model Content

[0005] To address the aforementioned problems of existing pulverizers, such as "cumbersome disassembly and maintenance, serious dust emission, and uncontrollable operating conditions," this utility model provides a visual, dust-free, quick-disassembly pulverizer.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: a visual dust-free quick-release shredder, including a support frame, a feeding box, a shredding chamber and a collection drawer, wherein a drive assembly is provided on the outer wall of the shredding chamber, and the output shaft of the drive assembly passes through the side wall of the shredding chamber and is connected to the shredding blade assembly disposed inside the shredding chamber; the shredding chamber is detachably installed on the support frame through a plug-in assembly; The pulverizing chamber is also equipped with a dust collection component; The bottom of the feeding box is fixedly installed on the support frame, and a rotating feeding assembly is provided inside it; The collection drawer is movably mounted on the bottom of the support frame; When the crushing chamber is pressed and closed onto the support frame, the outlet of the rotating feeding assembly is directly opposite the crushing blade assembly.

[0007] Furthermore, the plug-in assembly includes positioning grooves evenly formed on the inner wall of the support frame, and positioning strips evenly fixed to the outer wall of the crushing chamber and adapted to the positioning grooves.

[0008] Furthermore, the pulverizing chamber is a rectangular frame structure that runs vertically through the interior and exterior, and multiple sets of transparent observation windows are provided on the side wall of the pulverizing chamber.

[0009] Furthermore, the inside of the crushing chamber is equipped with an inclined feeding plate with a preset tilt angle of 30°-45°.

[0010] Furthermore, the vacuuming assembly includes a rectangular vacuuming pipe with multiple sets of through holes evenly distributed at the bottom, a pipe fixing clamp sleeved on the rectangular vacuuming pipe, and a dust passage pipe connected to the rectangular vacuuming pipe; The rectangular suction pipe is located below the inclined feed plate; The pipe fixing clamps secure the rectangular suction pipe to the inner wall of the pulverizing chamber using fasteners. The dust vent pipe extends through one of the sets of transparent observation windows to the outside of the crushing chamber, and is used to connect to an external collection device.

[0011] Furthermore, the feeding box consists of a conical hopper, a rectangular cylinder connected to the lower end of the conical hopper, and a pressure cap; The pressure cap is fixed to the support frame by bolts, and the crushing chamber is tightly pressed into the support frame; The rotary feeding assembly is located inside the rectangular tube.

[0012] Furthermore, the rotary feeding assembly includes a rotary motor fixed to the outer wall of the rectangular cylinder, a drive shaft horizontally mounted inside the rectangular cylinder, and multiple sets of feeding fan blades uniformly fixed to the drive shaft along the axial direction. The output shaft of the rotary motor rotates through the rectangular tube and is fixed to the drive shaft.

[0013] Furthermore, a pull-out filter plate is movably inserted into the collection drawer.

[0014] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure: 1. The system enables rapid assembly and disassembly of the grinding chamber and ensures reliable sealing, effectively preventing cross-contamination. Through the coordinated operation of the support frame, pressure cap, and plug-in components, initial positioning and guidance are achieved via the insertion of positioning strips and positioning slots. The pressure cap is then tightened with bolts to form a stable and reliable mechanical lock and seal. This structure allows for rapid assembly and disassembly of the grinding chamber without tools, greatly simplifying cleaning, maintenance, screen replacement, and blade assembly overhaul processes, significantly reducing equipment downtime. Simultaneously, the reliable sealing effectively prevents leakage of coarse and fine powders, especially highly active and high-value fine powders, fundamentally eliminating the risk of cross-contamination between different batches and formulations, meeting the stringent cleanliness requirements of cosmetic production. 2. It achieves efficient dust collection at the source and effective separation of coarse and fine powders during the crushing process. A rectangular suction pipe located below the crushing blade assembly and with multiple evenly spaced through-holes creates a negative pressure suction zone immediately upon dust generation, efficiently capturing micron-sized fine powders at the source. Combined with external dust collection equipment, these high-value-added fine powder materials (such as nano-titanium dioxide and mica) can be effectively recovered, significantly improving material utilization, reducing production costs, and completely solving the problem of dust dispersion in the cleanroom, creating a dust-free working environment.

[0015] 3. Real-time visual monitoring of the crushing and grading process has been achieved, improving product quality controllability. Multiple transparent observation windows installed on the side wall of the crushing chamber allow operators to observe the crushing status of the materials inside, the distribution of coarse and fine powders, and the working status of the blade assembly in real time. This enables operators to intuitively judge the degree of crushing, adjust parameters in a timely manner to optimize the ratio of coarse to fine powders, and immediately detect and address material jamming, agglomeration, or abnormal wear, thereby ensuring the stability and consistency of the product particle size distribution and improving the controllability of the production process and product quality.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-7 As shown, the present invention provides a visual dust-free quick-release shredder, including a support frame 1, a feeding box 2, a shredding chamber 3, and a collection drawer 4. The outer wall of the shredding chamber 3 is provided with a drive assembly 31, the output shaft of which passes through the side wall of the shredding chamber 3 and is connected to the shredding blade assembly 32 disposed inside the shredding chamber 3. The shredding chamber 3 is detachably installed on the support frame 1 through a plug-in assembly 33. A dust collection assembly 34 is also provided on the shredding chamber 3. The bottom of the feeding box 2 is fixedly installed on the support frame 1, and a rotating feeding assembly 24 is disposed inside it. The collection drawer 4 is movably installed at the bottom of the support frame 1; the collection drawer 4 has an insertion slot, and a pull-out filter plate 41 can be movably inserted into the insertion slot. The movable collection drawer 4 is convenient to be quickly pulled out and transferred after the material is full, avoiding the disassembly of other components and improving the material collection efficiency. The pull-out filter plate 41 is easy to remove for cleaning and replacement. It can collect finished materials and further block large particles and filter dust, achieving effective separation of materials and dust, improving the quality of finished products and recycling efficiency. When the crushing chamber 3 is pressed and closed onto the support frame 1, the outlet of the rotating feeding component 24 is directly opposite the crushing blade assembly 32. Through modular structural design, the crushing chamber 3 and the support frame 1 are detachably connected, and the dust collection function and the rotating feeding component 24 are integrated, realizing the rapid assembly, disassembly and maintenance of the equipment. At the same time, the alignment design of the rotating feeding component 24 and the crushing blade assembly 32 ensures that the material is accurately fed into the crushing area, improving crushing efficiency and operational continuity.

[0022] like Figure 4-6 As shown, the plug-in assembly 33 includes positioning grooves 331 evenly opened on the inner wall of the support frame 1, and positioning strips 332 evenly fixed on the outer wall of the crushing chamber 3 and adapted to the positioning grooves 331. By adopting the plug-in structure of positioning grooves 331 and positioning strips 332, the crushing chamber 3 can be quickly positioned and mechanically locked. Installation and disassembly can be completed without additional tools, which significantly improves the equipment maintenance efficiency and operation convenience.

[0023] like Figure 1-5 As shown, the crushing chamber 3 is a rectangular frame structure that runs vertically through the interior. Multiple transparent observation windows 35 are installed on the side walls of the crushing chamber 3. These windows are made of polycarbonate (PC) or wear-resistant acrylic glass (PMMA), providing high wear resistance. The inner walls are coated with an anti-stick coating (such as Teflon). The rectangular structure provides an unobstructed path for material to fall, reducing material stagnation points and preventing clumping or dust accumulation. It also facilitates compatibility with the rectangular interfaces of the feeding box 2 and the collection drawer 4. The transparent observation windows 35 allow for real-time observation of the material crushing status and the operation of the blade assembly, enabling timely detection of problems such as material jamming and blade malfunctions, thus improving operational safety and process controllability. Inside the crushing chamber 3, an inclined feed plate 36 with a preset tilt angle of 30°-45° is installed. The inclined feed plate 36 guides the material to flow towards the crushing area, preventing material splashing or accumulation and improving crushing efficiency and material utilization.

[0024] like Figure 1-4 As shown in Figure 7, the dust collection assembly 34 includes a rectangular dust collection pipe 341 with multiple sets of through holes evenly distributed at the bottom, a pipe fixing clamp 342 fitted onto the rectangular dust collection pipe 341, and a dust venting pipe 343 connected to the rectangular dust collection pipe 341. The rectangular dust collection pipe 341 is located below the inclined feed plate 36 and is situated in the core dust-generating area of ​​the crushing operation. The through holes face downwards, and the diameter, number, and distribution of the through holes can be optimized according to the dust properties and system air pressure and volume to form an effective negative pressure coverage area, ensuring that dust is captured immediately after it is generated, and minimizing dust diffusion. The dust venting pipe 343 passes through a transparent observation window 35 on one side and extends outside the chamber for connecting to external collection equipment (this equipment typically includes a dust pump that provides power and a dust collection bag for collecting light fine powder, not shown in the figure). A sealing structure is provided at the penetration point of the dust venting pipe 343 to prevent air leakage and ensure dust collection efficiency. During operation, the external collection device is activated, creating a stable negative pressure within the rectangular suction pipe 341. Fine powder generated during the crushing process enters the rectangular suction pipe 341 through the through-holes under the influence of airflow, and is then discharged to the external collection device via the dust removal pipe 343. This achieves efficient recovery and resource utilization of the fine powder, reducing material loss. Simultaneously, by promptly removing light fine powder, the system reduces airflow disturbance within the chamber, facilitating the rapid settling of coarser particles and indirectly improving the separation effect between coarse and fine powders.

[0025] like Figure 1-4 As shown, the feeding box 2 consists of a conical hopper 21, a rectangular cylinder 22 connected to the lower end of the conical hopper 21, and a pressure cover 23. The pressure cover 23 is fixed to the support frame 1 by bolts 231, and tightly presses the crushing chamber 3 into the support frame 1. A silicone sealing gasket is provided between the pressure cover 23 and the support frame 1 to prevent dust leakage from the support frame 1. The rotating feeding assembly 24 is located inside the rectangular cylinder 22. The conical hopper 21 facilitates the concentrated falling of materials. The structure of the pressure cover 23, while fixing the feeding box 2, also presses the crushing chamber 3, assisting in the quick fixing or disassembly of the crushing chamber 3, enhancing the overall structural stability, and preventing dust. To prevent overflow and ensure sealing, the rotary feeding assembly 24 includes a rotary motor 241 fixed to the outer wall of the rectangular cylinder 22, a drive shaft 242 horizontally rotatably installed inside the rectangular cylinder 22, and multiple sets of feeding fan blades 243 uniformly fixed axially on the drive shaft 242. The output shaft of the rotary motor 241 rotates through the rectangular cylinder 22 and is fixed to the drive shaft 242. The rotary motor 241 drives the drive shaft 242 to rotate the fan blades. The material falling amount can be controlled and adjusted through the intermittent pushing of the fan blades, avoiding the accumulation of material in the bin or equipment overload caused by excessive material input, and ensuring the continuity and stability of the crushing process.

[0026] In practical use 1. Equipment preparation: Align the positioning strip 332 on the outer wall of the crushing chamber 3 with the positioning groove 331 on the inner wall of the support frame 1, insert it along the groove until the chamber body fits against the bottom of the support frame 1, then fix the cover 23 of the feeding box 2 to the top of the support frame 1 with bolts 231, and use the cover 23 to tightly press the crushing chamber 3 (ensure sealing and rotate the outlet of the feeding component 24 so that it faces the crushing blade assembly 32 inside the crushing chamber 3), and then connect the dust pipe 343 of the dust collection component 34 to the external dust collection device to complete the equipment assembly.

[0027] 2. Material feeding and feeding: Open the feed port of the conical hopper 21 at the top of the feeding box 2, pour the material to be crushed into the hopper, and then start the rotary motor 241 of the rotary feeding assembly 24. The motor drives the drive shaft 242 to drive the feeding fan blade 243 to rotate. Through the intermittent pushing of the fan blade, the material is conveyed from the outlet of the rectangular cylinder 22 to the crushing chamber 3 at a controllable speed.

[0028] 3. Crushing Operation Stage: Start the drive assembly 31 on the outer wall of the crushing chamber 3. The output shaft of the drive assembly 31 drives the internal crushing blade assembly 32 to rotate at high speed. At the same time, the external collection device is turned on, so that the rectangular dust suction pipe 341 in the crushing chamber 3 forms a negative pressure. The material is guided to the core area of ​​the crushing blade assembly 32 through the inclined feed plate 36 and is quickly crushed. The fine powder generated during the crushing process is sucked in through multiple sets of through holes at the bottom of the dust suction pipe and then discharged to the external collection device through the dust vent pipe 343. The coarse powder quickly settles into the collection drawer 4. The operator can monitor the crushing status of the material (such as particle size and accumulation) and the operation of the crushing blade assembly 32 in real time through the transparent observation window 35 on the side wall of the crushing chamber 3. If the material is stuck or the blade assembly is abnormal, the equipment can be shut down immediately for handling.

[0029] 4. Finished Product Collection and Equipment Maintenance: After the crushing operation is completed, turn off the drive assembly 31, rotary motor 241, and external dust collection device in sequence. After the crushing blade assembly 32 has completely stopped operating, pull out the collection drawer 4 from the bottom of the support frame 1. The pull-out filter plate 41, which is movably inserted inside the drawer, receives the crushed finished material and filters out residual dust. The filter plate can be directly removed to collect the finished product. During regular cleaning, the filter plate can be pulled out for cleaning or replacement. When maintenance is required inside the crushing chamber 3, simply loosen and remove the fixing bolts 231 of the pressure cover 23, and the crushing chamber 3 can be pulled vertically upward along the positioning groove 331. This allows for quick inspection and cleaning of the crushing blade assembly 32 without disassembling other parts, greatly improving the maintainability of the equipment.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
