Description

Technical Field

[0001] This utility model relates to a crusher. Background Technology

[0002] Currently, food processing and snack food production often generate sheet-like wet materials, such as potato chip wrappers or leftover wrapper scraps containing moisture. To achieve resource recycling and reuse, these sheet-like wet materials usually need to be crushed into granules for further processing or use.

[0003] Most existing crushing equipment adopts a guillotine or large cutting structure, which crushes materials by cutting them with blades. While this type of structure can perform basic crushing functions, it still has the following shortcomings: Traditional cutting tools mainly rely on shearing or cutting action, which makes them less adaptable to sheet-like wet materials, and they are prone to problems such as incomplete crushing or uneven particle size.

[0004] To ensure cutting force, traditional equipment is generally bulky and takes up a lot of space, which is not conducive to small-scale production lines or decentralized applications.

[0005] Guillotine cutting generates significant impact during operation, which can produce high noise levels and negatively impact the production environment. Utility Model Content

[0006] The purpose of this invention is to provide a pulverizer with a compact structure, low noise, and excellent pulverizing effect.

[0007] The purpose of this utility model is achieved as follows: A pulverizer includes a motor and a pulverizing device. The pulverizing device includes a housing and a pulverizing assembly. The housing is provided with a pulverizing chamber and has an inlet and an outlet communicating with the pulverizing chamber. The pulverizing assembly is movably placed inside the pulverizing chamber. The crushing assembly includes a base, a scraper component, and impact blocks. The impact blocks are rotatably spaced on the base, and the scraper component is detachably fixed to the base. The motor's shaft passes through the housing and extends into the crushing chamber to connect with the base. The motor drives the base to rotate, and the scraper component rotates with the base. During the rotation of the base, centrifugal force is generated and acts on the striking block, causing it to unfold and rotate synchronously with the base.

[0008] By setting rotatable striking blocks on the base, and using the centrifugal force generated during the rotation of the base to unfold the striking blocks for striking, combined with the scraper component that rotates with the base to scrape the material, the flaky wet material can be effectively struck, turned over and fully contacted with the scraper, achieving a synergistic effect of crushing and scraping. This not only improves crushing efficiency, but also makes the granular material more uniform. The equipment has a compact structure and low noise, making it suitable for the recycling and reuse of wet material residue.

[0009] When the discharge port is equipped with a screen or mesh structure, the material must pass through the mesh to be discharged after crushing, which can effectively limit the size of the discharged particles, making the crushed particles more uniform and controllable, avoiding the mixing of excessively large particles, improving product quality and consistency, and realizing the integration of crushing and screening, simplifying the subsequent processing flow.

[0010] The objective of this utility model can also be achieved by the following technical measures: Furthermore, it also includes a screen, which is disposed inside the grinding chamber, and the grinding component is placed inside the screen.

[0011] By installing a screen inside the crushing chamber, the material must pass through the screen before it can be discharged when the crushing components are working. This effectively limits the particle size, ensures that the output particles are uniform, integrates crushing and screening, improves product quality, and simplifies subsequent processes.

[0012] Furthermore, the outer wall of the seat is spaced apart with connecting cavities, the connecting cavities contain connecting columns, the striking block has a connecting hole larger than the connecting column, one end of the striking block extends into the connecting cavity, the connecting column passes through the connecting hole, and the striking block rotates around the connecting column as the rotation center.

[0013] By setting a connecting cavity on the outer wall of the seat and arranging a connecting column inside the cavity, one end of the striking block is inserted into the connecting cavity and the connecting column is used as the center of rotation, so that the striking block has a reliable rotating installation structure, which can smoothly unfold under the action of centrifugal force and maintain stable rotation, thus improving the reliability of crushing.

[0014] Furthermore, the base includes at least two pressure plates and a connecting post. The pressure plates are stacked together, and an installation area is formed between adjacent pressure plates. Each pressure plate has a through hole along its circumference. The connecting post passes through the through hole of the pressure plate and is locked to form the base. The installation area forms the connecting cavity corresponding to the position of the connecting post.

[0015] This type of base is composed of multiple pressing plates and connecting columns stacked and locked together. The installation area between adjacent pressing plates naturally forms a connecting cavity, which allows the striking blocks to be easily inserted and rotated with the connecting column as the rotation center. This structure not only simplifies the installation and disassembly process of the striking blocks and improves assembly efficiency, but also allows multiple striking blocks to be installed at the same time, increasing the effective number of strikes, thereby expanding the crushing range, enhancing the striking force, and significantly improving the overall crushing effect.

[0016] Furthermore, the scraper component is fixed to the front end face of the base.

[0017] The scraper component is fixed on the front end face of the seat body, so that the scraper preferentially contacts materials during rotation, which can scrape and turn the materials, ensure that the materials are fully exposed to the action range of the beating blocks, and improve crushing uniformity and efficiency.

[0018] Further, the scraper component comprises a bottom plate and scrapers, connecting portions are arranged at intervals along the circumferential direction of the bottom plate, and the scrapers are arranged on the connecting portions.

[0019] The scraper component adopts a combined structure of the bottom plate and the scrapers, a plurality of connecting portions are uniformly distributed along the circumferential direction of the bottom plate, and the scrapers are mounted on the connecting portions, which can form a multi-point scraping effect during rotation, expand the scraping range, enhance the sufficiency of material turning and crushing, and meanwhile has flexible disassembly and assembly and convenient maintenance.

[0020] Further, one end of the beating block is a "convex"-shaped end portion.

[0021] The end portion of the beating block is designed in a "convex" shape, which contacts materials through the corner positions of the protruding portion to achieve multi-angle beating, expand the beating range, enhance impact force, and thus achieve a better crushing effect.

[0022] Further, steps are arranged at intervals on the side wall of the "convex"-shaped end portion.

[0023] Steps are arranged on the side wall of the "convex"-shaped end portion, so that the corner positions of the steps can also participate in beating during rotation, further increasing the beating range and the number of contact points, and improving the uniformity and completeness of crushing.

[0024] Further, the housing comprises a bottom shell, a face cover, a lock and a feeding hopper, the bottom shell is provided with the crushing cavity, the face cover is rotatably arranged on the bottom shell, and the face cover can be rotated to open or close the bottom shell; the lock is arranged on the bottom shell, and the lock locks or unlocks the face cover; the face cover is provided with the feeding port, the feeding hopper is arranged on the face cover, the feeding hopper communicates with the feeding port, and the bottom of the bottom shell is provided with the discharging port.

[0025] The housing adopts a combined structure of the bottom shell and the face cover, the face cover can be rotated to open or close and is reliably locked by the lock. Meanwhile, the feeding port and the feeding hopper are arranged on the face cover, and the discharging port is arranged at the bottom of the bottom shell. This design not only facilitates feeding and discharging, but also facilitates cleaning and maintenance of the equipment, improving the convenience and safety of use.

[0026] Further, a frame is further comprised, and the housing and the motor are fixed on the frame.

[0027] By fixing the housing and the motor on the frame, the overall structure of the whole machine is stable, which can effectively reduce vibration and displacement during operation and ensure long-term stable operation of the equipment.

[0028] The beneficial effects of this utility model are as follows: This invention utilizes a rotating striking block mounted on a base, along with a scraper component fixed to the front end of the base. During high-speed rotation of the base, the striking block unfolds under centrifugal force, delivering high-frequency impacts, while the scraper component scrapes and tumbles the material, achieving coordinated crushing through impact and scraping. This design avoids the shortcomings of a single cutting method, ensuring that flaky wet materials are thoroughly crushed and dispersed, resulting in high crushing efficiency and more uniform particle size.

[0029] In this invention, the crushing component is placed inside a screen, and the material must be screened through the screen before it can be discharged, thereby effectively limiting the size of the discharged particles and ensuring that the crushed particles are uniform. Unqualified large particles are continued to be struck and scraped inside the screen until they meet the requirements, avoiding the mixing of large particles and improving product quality. At the same time, crushing and screening are integrated, reducing subsequent processing steps.

[0030] This invention features a base structure with multiple stacked pressure plates locked together by connecting posts. The striking blocks are reliably rotatably connected to the connecting posts via connecting holes. This design not only facilitates the quick installation and disassembly of the striking blocks, reducing assembly difficulty and maintenance costs, but also increases the number of striking blocks, thereby expanding the striking range and further improving the crushing effect.

[0031] This invention features a "convex" shaped structure at the end of the striking block, with steps spaced at intervals on its sidewalls. This allows the striking block to make multi-point, multi-angle impact contact with the material through the convex and step corners during rotation, thereby significantly expanding the impact range and enhancing the impact force and crushing ability. This structure not only improves the uniformity and thoroughness of the material being struck, but also increases the crushing efficiency without increasing the motor power, further improving particle uniformity and resulting in better crushing effect.
