Description

Technical Field

[0001] This utility model relates to the field of fiberboard processing, and in particular to a fiberboard processing crusher. Background Technology

[0002] Fiberboard is a type of engineered wood product made primarily from wood fibers or other plant fibers through processes such as crushing, separating, drying, gluing, molding, and hot pressing. During the production process, the raw materials need to be crushed to form a fibrous structure, which facilitates the processing of the fiber materials.

[0003] Currently, a Chinese patent application with publication number CN 220261332 U and publication date of December 29, 2023, proposes a shredder for fiberboard processing, including a shredder box. The shredder box has a rotating shaft and a connecting rod rotatably connected inside. The outer surface of the rotating shaft is fixedly fitted with several cutting blades. One end of the connecting rod passes through the shredder box and extends to the outside of the shredder box. The end of the connecting rod extending to the outside of the shredder box is fixedly connected to a knob. The outer surface of the connecting rod has several sets of threads. The outer surface of each set of threads is threadedly connected to a fixing plate. A grinding disc is provided on one side of each pair of fixing plates.

[0004] When in use, the structure of cutting blades, crushing components, transmission components and motors allows larger waste materials to be cut into sizes that are easy for the crushing rollers to crush before crushing.

[0005] Regarding the aforementioned technologies, when the crushing component processes and crushes the cut raw materials, it uses two rotating crushing rollers to break the materials. However, the crushing rollers crush the materials by squeezing, which easily produces flakes of different sizes when crushing fiberboard. The crushed fibers are prone to having problems such as excessively large particles and uneven particle size. Utility Model Content

[0006] In order to make the particles of fiberboard more uniform after crushing and improve the crushing quality of fiberboard, this utility model provides a fiberboard processing crusher.

[0007] This utility model provides a fiberboard processing pulverizer, which adopts the following technical solution:

[0008] A fiberboard processing crusher includes: a casing, a crushing component, and a drive component. The casing has a feed inlet and a discharge outlet. The crushing component is located inside the casing, below the feed inlet. The drive component is located outside the casing and is drively connected to the crushing component. A grinding component is also located inside the casing, below the crushing component. The grinding component includes a grinding roller and a grinding plate. Both the grinding roller and the grinding plate have grinding teeth. The grinding plate is fixedly located inside the casing and is inclined. The grinding roller is rotatably located above the grinding plate. A discharge gap is left between the grinding roller and the grinding plate. The grinding roller is drively connected to the drive component.

[0009] By adopting the above technical solution, a grinding component is set below the crushing component. The crushing component breaks larger fiberboard pieces into smaller chunks. The crushed chunks fall from the crushing component into the grinding area. The grinding roller rotates under the drive of the drive component, causing the grinding teeth on the grinding roller to engage with the grinding teeth on the grinding plate to rub against the small fiberboard pieces, performing fine grinding and breaking the fiberboard into fine particles. By setting the grinding plate to an inclined position, the material can slide down under gravity to the position between the grinding roller and the grinding plate for friction crushing. Finally, the crushed material passes through the gap between the grinding roller and the grinding plate and is discharged from the outlet of the machine. In this way, by setting grinding rollers and grinding plates to break the fiberboard, the crushed fiberboard particles are smaller and more uniform, improving the crushing quality and product uniformity.

[0010] Optionally, the chassis is also provided with an adjustment component for adjusting the height of the grinding roller.

[0011] By adopting the above technical solution, the adjustment component can adjust the height of the grinding roller, thereby changing the size of the discharge gap between the grinding roller and the grinding plate, and thus adjusting the size of the particles after the fiberboard is ground. When it is necessary to adjust the particle size of the fiberboard after crushing, the adjustment component is operated to drive the grinding roller to rise or fall, thereby increasing or decreasing the gap between the grinding roller and the grinding plate to adapt to different materials or crushing requirements, ensuring that the degree of grinding is controllable, enabling the equipment to flexibly adapt to various crushing needs, and improving the versatility of the equipment and the stability of product quality.

[0012] Optionally, the adjustment assembly is provided in two sets, with the two sets of adjustment assemblies respectively disposed on both sides of the grinding roller. The adjustment assembly includes a fixed block and a lead screw pair. The fixed end of the lead screw pair is fixedly disposed on the outside of the machine housing in the vertical direction, and the fixed block is fixedly disposed on the movable end of the lead screw pair. The grinding roller is rotatably disposed on the fixed block.

[0013] By adopting the above technical solution, the adjustment component uses a lead screw pair structure. When adjusting the height, the lead screw in the lead screw pair is driven to rotate, so that the moving end of the lead screw pair drives the fixed block and the grinding roller to rise and fall smoothly, accurately controlling the gap between the grinding roller and the grinding plate. The two sets of opposite lead screw pairs work simultaneously, which can reduce the probability of the grinding roller deviating on one side and improve the accuracy of the grinding roller movement. At the same time, the unidirectional driving characteristic of the lead screw pair is also used to reduce the probability of the fixed block of the grinding roller moving when not actively adjusted, so as to achieve uniform and reliable gap control, improve the grinding effect and facilitate operation.

[0014] Optionally, the grinding roller is connected to the drive assembly via a belt drive, and a tensioning wheel is also provided on the chassis for tensioning the belt.

[0015] By adopting the above technical solution, when the adjustment component adjusts the position of the grinding roller, the distance between the grinding roller and the drive component will change relatively. Using a belt as the power transmission component between the grinding roller and the drive component, and using a tensioning pulley to maintain belt tension, stable power transmission can be maintained even when the position of the grinding roller changes. During operation, the drive component drives the belt to rotate, and the tensioning pulley can be automatically adjusted by a spring or manually adjusted to keep the belt taut during transmission, ensuring stable power transmission between the drive component and the grinding roller. Thus, by using a belt to transmit power and setting a tensioning pulley to maintain belt tension, stable power transmission can be maintained even when the position of the grinding roller changes, improving the reliability and continuity of equipment operation.

[0016] Optionally, a guide plate is provided inside the chassis, which is located between the crushing component and the grinding component, and is used to limit the drop position of the material.

[0017] By adopting the above technical solution, the guide plate is set between the crushing component and the grinding component to guide the falling trajectory of the material. After crushing, the material is guided by the guide plate and falls into the center of the grinding area of ​​the grinding roller and grinding plate. This reduces the probability of material scattering or deviating, makes the material enter the grinding area more evenly, and improves the grinding efficiency and particle uniformity of the material.

[0018] Optionally, the inner wall of the chassis is also provided with a mounting platform, which is located below the guide plate and is inclined. The grinding plate is detachably fixed on the mounting platform, and the grinding teeth are located on the side of the grinding plate away from the mounting platform.

[0019] By adopting the above technical solution, the mounting platform is tilted and fixed to the inner wall of the machine box, and the grinding plate is detachably mounted on the mounting platform. During operation, the grinding plate is fixed on the mounting platform, and the grinding teeth of the grinding plate grind the grinding roller. After the grinding plate is worn, it can be easily removed from the mounting platform for replacement, which facilitates quick replacement and maintenance, extends the equipment life and reduces downtime.

[0020] Optionally, a brush is also provided inside the chassis, the brush being positioned above the grinding roller and in contact with the grinding roller.

[0021] By adopting the above technical solution, the brush is set above the grinding roller and in contact with the grinding roller to clean the roller surface and reduce the fiberboard particles adhering to the grinding roller. When the grinding roller rotates, the brush continuously sweeps away the adhering material debris, keeping the roller surface smooth. This can reduce the problem of reduced crushing efficiency caused by material adhering to the grinding roller, making the grinding process smoother and more stable.

[0022] Optionally, a vibrating motor, a screen, and a powder hopper are also provided. The screen is fixedly installed on the machine casing near the discharge port, the vibrating motor is fixedly installed on the screen, and the powder hopper is fixedly installed on the machine casing below the screen.

[0023] By adopting the above technical solution, the screen is set at the discharge port, and the vibrating motor drives the screen to vibrate. The powder falls from the screen mesh and is collected in the powder bin below. The ground material is screened by the screen, so that the dust generated during grinding is collected in the powder bin below the screen, and the broken fiberboard particles slide down the screen and are discharged from the discharge port. On the one hand, this can reduce the pollution caused by dust scattered in the surrounding environment, and on the other hand, it can screen out excessively small fiberboard dust and improve the consistency of fiberboard crushed particles.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0025] This application uses grinding rollers and grinding plates to break down fiberboard, which results in smaller and more uniform fiberboard particles after crushing, thus improving the crushing quality and product uniformity.

[0026] By setting the adjustment component, the height of the grinding roller can be adjusted, thereby changing the size of the discharge gap between the grinding roller and the grinding plate, and thus adjusting the particle size after the fiberboard is ground to adapt to different materials or crushing requirements, ensuring that the degree of grinding is controllable, enabling the equipment to flexibly adapt to various crushing needs, and improving the versatility of the equipment and the stability of product quality.

[0027] A brush is installed on the outside of the grinding roller to clean the roller surface and reduce the fiberboard particles adhering to the grinding roller. When the grinding roller rotates, the brush continuously sweeps away the adhering material debris, keeping the roller surface smooth. This reduces the problem of reduced crushing efficiency caused by material adhering to the grinding roller, making the grinding process smoother and more stable. Attached Figure Description

Detailed Implementation

[0032] The following combination Figures 1 to 3 The present invention will be described in further detail below.

[0033] This utility model discloses a fiberboard processing pulverizer. (Refer to...) Figures 1 to 2 A fiberboard processing crusher mainly includes a casing 100, a crushing component 200, a drive component 300, and a grinding component 400. The casing 100 has a feed inlet 101 at the top and a discharge outlet 102 at the bottom. The crushing component 200 is installed inside the casing 100 below the feed inlet 101 and is used to perform preliminary crushing on the fed fiberboard. The grinding component 400 is located below the crushing component 200 and is used to perform fine friction grinding on the material after preliminary crushing by the crushing component 200. The drive component 300 is located outside the casing 100 and provides power to the crushing component 200 and the grinding component 400.

[0034] During operation, fiberboard material is fed into the machine housing 100 through the feed port 101. After being crushed into appropriately sized blocks by the crushing component 200, the material falls into the grinding area under the action of gravity and then falls into the grinding component 400 for fine grinding. The material is finally crushed into fine and uniform particles and discharged from the gap to the discharge port 102. By using friction grinding instead of simple extrusion crushing, the uniformity and fineness of the fiberboard crushed particles are significantly improved, thus enhancing the crushing quality.

[0035] Reference Figure 1 and Figure 2 The chassis 100 is the main support and housing for the entire equipment. The chassis 100 consists of three parts: an upper cover, a middle frame, and a bottom frame. The middle frame and the bottom frame are fixedly connected by rubber sealing gaskets and bolts. The upper cover has a semi-circular structure, and the feed port 101 is located on the upper cover. One end of the upper cover is rotatably connected to the upper part of the middle frame, so that the upper cover can be opened for cleaning and maintenance. The middle frame and the bottom frame are both square frame structures, and the discharge port 102 is the opening position below the bottom frame. The crushing component 200 is installed on the middle frame, and the grinding component 400 is installed on the bottom frame.

[0036] Reference Figure 2 The crushing assembly 200 is installed inside the middle frame of the housing 100 and is located below the feed inlet 101. The crushing assembly 200 includes two crushing jaws that rotate relative to each other. One end of each crushing jaw is equipped with a drive motor, and the other end is equipped with a gear. The drive motor is connected to one of the crushing jaws, so that when the drive motor rotates, it can directly drive one of the crushing jaws to rotate, and drive the other crushing jaw to rotate relative to it through the gear.

[0037] After the material is fed into the feed inlet 101, it falls between the two crushing jaws of the crushing component 200. The material is initially cut and crushed by the two relatively rotating crushing jaws, breaking it into smaller pieces.

[0038] Reference Figure 2 and Figure 3The grinding assembly 400 includes a grinding roller 410 and a grinding plate 420. An inclined mounting platform 130 is installed inside the lower frame of the housing 100, located below the crushing assembly 200. One side of the grinding plate 420 has grinding teeth 411, and the other side is fixed to the mounting platform 130 by bolts. The grinding roller 410 is mounted on the lower frame of the housing 100 via an adjusting assembly 500, and its surface is also provided with grinding teeth 411. The grinding roller 410 is positioned above the grinding plate 420, and a one-millimeter gap is maintained between the grinding roller 410 and the grinding plate 420. This ensures that when the grinding roller 410 and the grinding plate 420 work together to grind the material, the ground material particles are limited to within one millimeter. When the material size needs to be adjusted, the grinding roller 410 can be moved upwards or downwards by the adjusting assembly 500, thereby adjusting the gap between the grinding roller 410 and the grinding plate 420.

[0039] In order to ensure that the material falling from the crushing component 200 can fall more accurately into the grinding area, a guide plate 120 is also provided inside the housing 100. The two ends of the guide plate 120 are fixed to the inner wall of the middle frame of the housing 100 by bolts. The guide plate 120 is inclined so that the material falling from the crushing component 200 can fall on the guide plate 120 and slide down the guide plate 120 into the grinding area.

[0040] To improve grinding efficiency and reduce the probability of crushed fiber particles adhering to the grinding roller 410 and causing blockage in the gap between the grinding roller 410 and the grinding plate 420, a brush 140 is also provided inside the machine housing 100. A support plate is provided inside the machine housing 100, and the brush 140 is vertically mounted on the support plate by bolts. The brush head of the brush 140 contacts the outer surface of the grinding roller 410 and can sweep off the particles attached to the surface of the grinding roller 410 when the grinding roller 410 rotates.

[0041] Reference Figure 1 The adjusting assembly 500 includes a lead screw pair 520 and a fixing block 510. A support is fixedly installed on the outer wall of the lower frame of the housing 100. Two lead screw pairs 520 are provided and fixedly installed on the support in the vertical direction. The two ends of the fixing block 510 are respectively installed on the slides of the two lead screw pairs 520. A bearing seat is provided above the fixing block 510, and the bearing in the middle of the grinding roller 410 is rotatably installed inside the bearing seat. When the lead screw pair 520 drives the fixing block 510 to rise, it can drive the grinding roller 410 to move upward, and vice versa.

[0042] To increase the stability of the movement of the grinding roller 410, adjustment components 500 are provided on both sides of the grinding roller 410, and the adjustment components 500 on both sides of the grinding roller 410 work synchronously.

[0043] In this embodiment, the drive assembly 300 is driven by a three-phase motor. Both the output shaft of the three-phase motor and the middle roller shaft of the grinding roller 410 are provided with pulleys, so that the drive assembly 300 drives the grinding roller 410 to rotate via the belt.

[0044] To ensure the belt remains tensioned when the adjusting component 500 moves the grinding roller 410, a tensioning wheel 110 is provided on the outer wall of the housing 100. The tensioning wheel 110 is rotatably mounted on the outside of the housing 100 via a slide support. The slide support has a slot, and the corresponding outer wall of the housing 100 has a mounting hole. Bolts are inserted into the slot and the corresponding mounting hole to fix the position of the tensioning wheel 110. Adjusting the position of the slot relative to the mounting hole and fixing it with bolts can adjust the position of the tensioning wheel 110. Thus, when the grinding roller 410 moves, adjusting the position of the tensioning wheel 110 can maintain belt tension, thereby enabling the drive component 300 to stably drive the grinding roller 410 to rotate.

[0045] Reference Figure 2 To ensure more uniform fiber particles discharged from outlet 102 and reduce dust pollution around the pulverizer, a vibrating motor 150, a screen 160, and a powder hopper 170 are installed below the grinding assembly 400. The screen 160 is inclined and located at the lower end of the grinding plate 420. The vibrating motor 150 is fixedly mounted on the screen 160, and the powder hopper 170 is placed below the screen 160. After the grinding assembly 400 grinds the material into particles, the fiber particles... The material will pass through the gap between the grinding roller 410 and the grinding plate 420, and slide down the grinding plate 420 to the screen 160. Since wood fibers have a certain toughness, most of the wood fibers will be fibrous or fluffy after grinding, and a small part will form powder. After the ground material falls on the screen 160, the powder will fall through the screen holes of the screen 160 and be collected in the powder hopper 170, while the fibrous particles will slide down the screen 160 and be discharged from the discharge port 102.

[0046] The implementation principle of the fiberboard processing pulverizer of this utility model embodiment is as follows:

[0047] After the fiberboard raw material is fed into the feed inlet 101 of the casing 100, it first falls into the working area of ​​the crushing component 200. The crushing component 200 rotates and squeezes the raw material to cut it into smaller pieces. The crushed material then falls downwards and is guided by the guide plate 120 to the central area of ​​the grinding component 400, where it falls onto the inclined grinding plate 420. Under the action of gravity, the material slides along the inclined surface of the grinding plate 420 towards the discharge gap between the grinding roller 410 and the fixed grinding plate 420. At the same time, the drive component 300 drives the material through a belt (the belt is made of tension). The tensioning wheel 110 keeps the grinding roller 410 taut, driving it to rotate at high speed. The grinding teeth 411 on the grinding roller 410 mesh and rub against each other with the grinding teeth 411 on the fixed grinding plate 420, which strongly crushes, shears, and rubs the material falling into the gap, achieving fine grinding and further crushing small pieces of material into fine and uniform particles. Finally, the ground mixture falls onto the vibrating screen 160. The vibrating motor 150 drives the screen 160 to vibrate, and the fibrous particles slide along the screen 160 to the discharge port 102 for discharge. The dust particles pass through the mesh of the screen 160 and fall into the powder hopper 170 below for collection.

[0048] During the grinding process, the brush 140 located above the grinding roller 410 works continuously to sweep off the debris adhering to the roller surface and keep the grinding roller 410 clean.

[0049] When it is necessary to adjust the particle fineness, the height of the grinding roller 410 is precisely adjusted by the adjustment components 500 (screw pair 520 and fixed block 510) on both sides of the grinding roller 410, thereby changing the gap between the grinding roller 410 and the grinding plate 420.

[0050] Thus, through the preliminary processing of the crushing component 200 and the fine friction grinding of the grinding component 400, combined with subsequent screening, a fiberboard pulverized product with fine and uniform particles and effective dust collection is finally obtained, which significantly improves the pulverization quality and product consistency.

[0051] In summary, this application breaks down fiberboard by setting up a grinding roller 410 and a grinding plate 420, resulting in smaller and more uniform fiberboard particles after crushing, thus improving the crushing quality and product uniformity. By setting up an adjustment component 500, the height of the grinding roller 410 can be adjusted, thereby changing the discharge gap between the grinding roller 410 and the grinding plate 420, and further adjusting the particle size of the ground fiberboard to adapt to different materials or crushing requirements. This ensures that the degree of grinding is controllable, allowing the equipment to flexibly adapt to various crushing needs, and improving the versatility of the equipment and the stability of product quality.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
