Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fiberboard production, and in particular to a fiberizing and gluing unit, a fiberizing and gluing device provided with the fiberizing and gluing unit, and a fiberboard production system provided with the fiberizing and gluing device. Background Art
[0002] The existing defibration and gluing equipment has a defibration and gluing unit which basically includes a sealing drum body and multiple groups of defibration knife groups. A rotating shaft is provided at both axial ends of the sealing drum body, and the rotating shafts at both ends are coaxially arranged, so that the defibration and gluing unit can be rotatably installed in the chassis of the defibration and gluing equipment through the rotating shafts at both ends. The multiple groups of defibration knife groups are distributed along the circumference of the sealing drum body, and the defibration knife groups are welded and fixed to the outer circumferential surface of the sealing drum body; in addition, a glue powder applying point is provided on the outside of the defibration and gluing unit in the chassis, so that the glue powder can be mixed into the fibers after the fiber clusters are broken up by the defibration and gluing unit, so as to ensure the strength of the fiberboard produced subsequently.
[0003] However, the shortcomings of existing fiberizing and sizing equipment are:
[0004] First, during the production and operation of the fiberizing and gluing equipment, the interior of the machine box is relatively closed and has poor ventilation, which makes it very easy for heat accumulation to cause fire accidents;
[0005] Second, since the rubber powder is applied at a single point, it is not evenly mixed with the dispersed fibers. To ensure that the strength of the fiberboard produced later meets the requirements, the amount of rubber powder applied needs to be increased, which increases production costs.
[0006] Third, the fiber disassembly knife group is mostly made of ordinary carbon steel, which makes the fiber disassembly knife group wear quickly, resulting in insufficient fiber disassembly. Therefore, the entire fiber disassembly and gluing unit must be replaced frequently, which reduces production efficiency and increases construction costs. Summary of the Invention
[0007] In order to solve the above problems, the main purpose of the present invention is to provide a defiberizing and sizing unit that can improve production quality, reduce production costs and ensure production safety.
[0008] Another object of the present invention is to provide a defibrination and sizing device provided with the above-mentioned defibrination and sizing unit.
[0009] Another object of the present invention is to provide a fiberboard production system equipped with the above-mentioned defiberizing and sizing device.
[0010] The cam is secured to the outside of the unit and has a plurality of slots for securing the cam, the slots for securing the cam to the outside of the unit and the plurality of slots for securing the cam to the outside of the unit.
[0011] As can be seen from the above, through the design of the fiber disintegration and gluing unit, glue powder can be added through the hollow cavity of the rotating shaft, so that when the fiber disintegration and gluing unit rotates, the glue powder is thrown into the interior of the cylinder by centrifugal force, so that the glue powder can enter the cylinder in a dispersed manner, and the glue powder is evenly moved out of the cylinder from the glue slurry slot of the cylinder to be mixed with the fiber clusters, thereby reducing the amount of glue powder applied and saving production costs; and during the rotation of the fiber disintegration and gluing unit, the air inlet impeller rotates to supply air to the inside of the cylinder, thereby reducing the temperature inside the chassis of the fiber disintegration and gluing equipment and the temperature of the blade head of the fiber disintegration knife group, avoiding fire accidents caused by heat accumulation in the chassis, and ensuring production safety. At the same time, the air supply of the air inlet impeller also helps to move the glue powder out of the glue slurry slot into the chassis, and can further improve the dispersion of the fiber clusters, so that the glue powder and the broken fibers are evenly and fully mixed.
[0012] A preferred solution is that the drum frame also includes multiple groups of spoiler units, which are distributed axially. The spoiler units are located in the cylinder. The spoiler units include more than two spoiler plates, which are distributed circumferentially along the rotating shaft and are connected to the rotating shaft.
[0013] As can be seen from the above, the spoiler unit can perform secondary dispersion on the rubber powder dispersed into the cylinder, and cooperate with the wind sent in by the air inlet impeller to make the rubber powder better move out of the rubber dispersion tank to mix with the broken fiber clusters, thereby further improving the mixing uniformity of the rubber powder and the broken fibers, so as to better reduce the amount of rubber powder applied while ensuring that the strength of the subsequently produced fiberboard remains unchanged, so as to further save production costs.
[0014] A further solution is that the cylinder is formed with a guide plate at each glue trough, and the guide plate extends axially. In the rotation direction of the fiber decomposition and gluing unit, the guide plate is inclined from the upstream end of the glue trough to the downstream end of the glue trough and extends obliquely toward the interior of the cylinder; the guide plate has a windward side and a leeward side, and in the rotation direction, the windward side is located at the downstream end of the leeward side, and a glue guiding channel is formed between the windward side and the leeward side of a guide plate located at the downstream end of the windward side.
[0015] As can be seen from the above, the guide plate is used to cooperate with the turning direction of the fiber disintegration and gluing unit, and the wind sent in by the air inlet impeller enables the glue powder to be better moved from the inside of the cylinder to the outside of the cylinder through the glue dispersing groove to mix with the broken fibers.
[0016] Another preferred solution is that a plurality of mounting grooves are formed on the outer peripheral wall of the cylinder, and the plurality of mounting grooves extend axially, and the mounting grooves are recessed from the outer peripheral wall of the cylinder into the cylinder. The plurality of mounting grooves and the plurality of bulk glue grooves are spaced apart in the circumferential direction of the cylinder, and the plurality of groups of defibrillating knife groups correspond one-to-one to the plurality of mounting grooves; the defibrillating knife group includes a knife holder and a plurality of knife heads, and the knife holder is detachably mounted in a corresponding mounting groove, and the plurality of knife heads are distributed axially, and the plurality of knife heads are mounted on the knife holder.
[0017] As can be seen from the above, the above design enables each set of defibrillating cutters to be replaced individually, thereby extending the overall service life of the defibrillating and gluing unit and reducing the maintenance and use costs of the defibrillating and gluing unit.
[0018] A further solution is that the cutter heads are made of alloy material; and the cutter heads of two adjacent defibration knife groups are staggered in the circumferential direction of the cylinder.
[0019] As can be seen from the above, the use of alloy materials to make the cutter head can improve the wear resistance of the cutter head, thereby extending the service life of the defibrillating knife group and reducing the full-cycle use cost of the defibrillating and gluing unit; and by designing the relative positions of the cutter heads of two adjacent defibrillating knife groups, the effect of the defibrillating and gluing unit on breaking up the fiber clusters can be improved, so as to improve the dispersion of the broken fiber clusters, so that the broken fibers can be more evenly and fully mixed with the glue powder.
[0020] Another preferred solution is that the air inlet impeller includes a wheel frame and multiple blades. The wheel frame is detachably connected to the cylinder. The multiple blades are distributed along the circumference of the wheel frame. The blades are installed on the wheel frame. When the defibrillation and gluing unit rotates, the blades supply air to the inside of the cylinder.
[0021] As can be seen from the above, the connection between the air inlet impeller and the cylinder is designed to be detachable, so that the air inlet impeller is replaceable, so that the air inlet impeller can be replaced according to different processing objects and processing requirements of the fiber disintegration and gluing unit, so as to adjust and change the air flow rate, temperature and the mixing state of the glue powder and the broken fibers in the box of the fiber disintegration and gluing equipment.
[0022] A further solution is that the number of the air inlet impellers is more than two, the inclination angles of the blades of the same air inlet impeller are equal, and the inclination angles of the blades of each air inlet impeller are not equal.
[0023] As can be seen from the above, by directly configuring multiple air inlet impellers with different design parameters, users can directly select corresponding air inlet impellers according to different processing objects and different processing requirements of the defibration and gluing unit without having to make or purchase additional air inlet impellers, which enables users to use the defibration and gluing unit more conveniently and is also helpful in guiding users on how to select a matching air inlet impeller.
[0024] In order to achieve another object of the present invention, the present invention provides a fiber defibrination and gluing device, including a chassis, a mixing bin inside the chassis, and the chassis also having a feed port and a discharge port, which are respectively connected to the mixing bin, wherein the fiber defibrination and gluing device also includes the above-mentioned fiber defibrination and gluing unit; a vent is provided on the chassis, the vent is connected to the mixing bin, the fiber defibrination and gluing unit is rotatably arranged in the mixing bin around its own rotation axis, the air inlet impeller is docked in the vent, and the two ends of the rotating shaft extend out of the chassis respectively.
[0025] As can be seen from the above, the defibrillating and gluing equipment equipped with the above-mentioned defibrillating and gluing unit can cool the chassis and the blade heads of the defibrillating knife group, and avoid fire accidents caused by heat accumulation in the chassis, thereby ensuring production safety; in addition, it also allows the glue powder and the broken up fibers to be evenly and fully mixed, reducing the amount of glue powder and reducing production costs; furthermore, each group of defibrillating knives can be replaced individually to extend the overall service life of the defibrillating and gluing unit and reduce the maintenance and use costs of the defibrillating and gluing unit.
[0026] A further solution is that the number of ventilation holes is more than two; the number of fiberizing and gluing units is more than two, and the more than two fiberizing and gluing units correspond one-to-one to the more than two ventilation holes; in the material moving direction of the fiberizing and gluing equipment, the two adjacent fiberizing and gluing units rotate toward each other, so that the blades of the fiberizing knife groups of the two adjacent fiberizing and gluing units rotate toward each other.
[0027] As can be seen from the above, the above design enables the fiber clusters to be fully broken up, thereby improving the dispersion of the broken fibers, thereby enabling the rubber powder to be more evenly and fully mixed with the broken fibers.
[0028] In order to achieve another object of the present invention, the present invention provides a fiberboard production system, which includes the above-mentioned fiberizing and sizing equipment.
[0029] As can be seen from the above, the fiberboard production system equipped with the above-mentioned fiberizing and gluing equipment can ensure that the chassis of the fiberizing and gluing equipment and the blade heads of the fiberizing knife group are well cooled, so as to avoid fire accidents caused by heat accumulation in the chassis and ensure production safety; in addition, the glue powder and the broken up fibers are evenly and fully mixed to reduce the amount of glue powder while ensuring that the strength of the produced fiberboard remains unchanged, thereby reducing production costs; furthermore, each group of fiberizing knives can be replaced individually to extend the overall service life of the fiberizing and gluing unit and reduce the maintenance and use costs of the fiberizing and gluing unit.

[0039] Fiber disintegration and sizing equipment embodiment
[0040] Reference Figure 1 and Figure 2The defibrination and gluing device 100 includes a defibrination and gluing unit 101, a chassis 102, and a bearing seat 103. The chassis 102 includes a mixing chamber 1021, and further includes a feed port 1022 and a discharge port 1023. Both the feed port 1022 and the discharge port 1023 are connected to the mixing chamber 1021. Preferably, in the height direction of the defibrination and gluing device 100, the feed port 1022 is located above the mixing chamber 1021, and the discharge port 1023 is located below the mixing chamber 1021. The feed port 1022 is used to receive fiber agglomerates to be processed and allow the fiber agglomerates to enter the mixing chamber 1021. The mixing chamber 1021 is used to provide the space required for mixing the dispersed fibers and the rubber powder. The discharge port 1023 is used to allow the mixed material of the dispersed fibers and the rubber powder to be discharged from the chassis 102, so that the discharged mixed material can be transferred to the subsequent equipment.
[0041] Combine Figure 3 and Figure 4 The defiberizing and gluing unit 101 includes a drum frame 1 and a plurality of defiberizing knife groups 2. The drum frame 1 includes a cylinder 11, an air inlet impeller 12, a sealing plate 13, a rotating shaft 14 and a plurality of flow-disturbing units 15.
[0042] Combine Figures 5 to 7 The outer peripheral wall of the cylinder 11 is provided with a plurality of adhesive dispersing grooves 111. The adhesive dispersing grooves 111 extend along the axial direction of the cylinder 11 and do not penetrate the cylinder 11 in the axial direction of the cylinder 11. That is, the first end of the adhesive dispersing groove 111 is provided near the first end of the cylinder 11, and the second end of the adhesive dispersing groove 111 is provided near the second end of the cylinder 11. In addition, the adhesive dispersing grooves 111 penetrate the cylinder wall of the cylinder 11 in the thickness direction of the cylinder wall of the cylinder 11, so that the interior of the cylinder 11 and the exterior of the cylinder 11 are in communication through the adhesive dispersing grooves 111, thereby allowing the adhesive powder inside the cylinder 11 to move to the exterior of the cylinder 11 through the adhesive dispersing grooves 111.
[0043] In addition, multiple bulk glue grooves 111 and multiple groups of defibrillating knife groups 2 are spaced apart in the circumferential direction of the cylinder 11, and the defibrillating knife groups 2 are connected to the cylinder 11. Preferably, multiple mounting grooves 112 are also formed on the outer peripheral wall of the cylinder 11, and the multiple mounting grooves 112 and the multiple bulk glue grooves 111 are spaced apart in the circumferential direction of the shaft. The mounting grooves 112 extend along the axial direction of the cylinder 11, and the mounting grooves 112 preferably pass through the cylinder 11 in the axial direction of the cylinder 11. The multiple groups of defibrillating knife groups 2 correspond one-to-one to the multiple mounting grooves 112. Among them, the defibrillating knife group 2 preferably includes a knife holder 21 and multiple knife heads 22, and the knife holder 21 is detachably mounted in a corresponding mounting groove 112; for example, the knife holder 21 can be detachably fixedly connected to the cylinder 11 by bolts, and for another example, the knife holder 21 can also be detachably fixedly connected to the cylinder 11 by a snap-fit structure. The plurality of blade heads 22 are distributed along the axial direction of the cylinder 11 and are all mounted on the blade holder 21. This design allows each set of defibration blades to be replaced individually. When the blade heads 22 of a defibration blade set 2 become blunt due to wear, the defibration blade set 2 can be replaced individually, eliminating the need to replace the entire defibration unit. This extends the overall service life of the defibration and gluing unit 101 and reduces the maintenance and operating costs of the defibration and gluing unit 101.
[0044] Furthermore, the cutter head 22 is preferably made of alloy material to improve the wear resistance of the cutter head 22, thereby extending the service life of the fiber removal knife group 2 and reducing the full cycle use cost of the fiber removal and gluing unit 101. Figure 8 In the axial direction of the cylinder 11, the blade heads 22 of the two adjacent groups of defibrillating knife groups 2 are preferably staggered with each other to improve the effect of the defibrillating and gluing unit 101 on breaking up the fiber clusters, thereby improving the dispersion of the broken fiber clusters and allowing the broken fibers to be more evenly and fully mixed with the glue powder.
[0045] The air inlet impeller 12 is mounted on the first end of the cylinder 11. Preferably, the air inlet impeller 12 includes a wheel frame 121 and a plurality of blades 122. The wheel frame 121 is detachably connected to the cylinder 11, making the air inlet impeller 12 replaceable. This allows the air inlet impeller 12 to be replaced according to the different processing objects and processing requirements of the defibrination and gluing unit 101, thereby adjusting and changing the air flow rate, temperature, and the mixing state of the rubber powder and the broken fibers within the housing of the defibrination and gluing device 100. The plurality of blades 122 are distributed circumferentially along the wheel frame 121. The blades 122 are mounted on the wheel frame 121 so that when the defibrination and gluing unit 101 rotates about its own rotation center, the blades 122 of the air inlet impeller 12 can supply air to the interior of the cylinder 11.
[0046] Furthermore, the defibrination and gluing unit 101 can be configured with more than two air inlet impellers 12. The blades 122 of the same air inlet impeller 12 have the same inclination angle, while the blades 122 of each air inlet impeller 12 have different inclination angles. By directly configuring multiple air inlet impellers 12 with different design parameters, users can directly select the appropriate air inlet impeller 12 based on the different processing objects and processing requirements of the defibrination and gluing unit 101, without having to manufacture or purchase additional air inlet impellers 12. This makes it more convenient for users to use the defibrination and gluing unit 101 and also helps guide users in selecting a matching air inlet impeller 12.
[0047] Of course, as another possible implementation method, the fan blades 122 can also be rotatably connected to the wheel frame 121 so that the opening of the fan blades 122 can be adjusted, thereby eliminating the need to replace the impeller to adjust the air flow rate, temperature, and the mixing state of the rubber powder and the broken fibers in the box. For example, a shaft and a screw can be provided on the fan blades 122, and the shaft and the screw can be coaxially arranged. When the fan blades 122 are mounted on the wheel frame 121, the rotating shaft 14 can be rotatably connected to the outer frame of the wheel frame 121. After the screw passes through the inner frame of the wheel frame 121, it is threadedly connected to the screw through a nut and the nut is adjacent to the wheel frame 121, thereby making the opening of the fan blades 122 adjustable. Preferably, a first clamping block can be provided on the shaft of the fan blades 122, and a first gear structure (such as a plurality of first clamping teeth distributed along the circumference of the shaft) can be provided on the outer frame of the wheel frame 121. ), so that the opening of the fan blade 122 can be adjusted by engaging the first block with different first teeth, and the opening of each fan blade 122 can be kept consistent; and / or, a second block can be provided at the screw of the fan blade 122, and a second gear structure (such as a plurality of second teeth distributed circumferentially along the shaft portion) can be provided at the outer frame of the wheel frame 121, so that the opening of the fan blade 122 can be adjusted by engaging the second block with different second teeth; wherein, as a variation of the design, the block can be provided on the wheel frame 121, and correspondingly, the gear structure can be provided on the fan blade 122.
[0048] The sealing plate 13 is installed at the second end of the cylinder 11, and the sealing plate 13 seals the second end of the cylinder 11 to prevent the wind sent in by the air inlet impeller 12 from being directly discharged from the second end of the cylinder 11 to the chassis 102 instead of entering the mixing bin 1021 of the chassis 102, thereby ensuring that the rubber powder can accurately enter the mixing bin 1021 of the chassis 102 and be evenly and fully mixed with the broken fibers.
[0049] The rotating shaft 14 passes through the air inlet impeller 12, the cylinder 11, and the sealing plate 13. The rotating shaft 14 has a hollow cavity 141. The hollow cavity 141 is recessed from the first end of the rotating shaft 14 to the second end of the rotating shaft 14 in the axial direction of the cylinder 11. The opening of the hollow cavity 141 is formed at the first end of the rotating shaft 14, and the hollow cavity 141 does not pass through the rotating shaft 14 in the axial direction of the cylinder 11. In addition, a plurality of hole groups are provided on the rotating shaft 14, and the plurality of hole groups are distributed along the axial direction of the cylinder 11. The hole groups include a plurality of through holes 142, and the plurality of through holes 142 are distributed along the circumference of the rotating shaft 14, and one through hole 142 penetrates the rotating shaft 14 along a radial direction of the rotating shaft 14, so that the through hole 142 connects the hollow cavity 141 and the glue trough 111, so that the glue powder put into the hollow cavity 141 can move through the through hole 142 and the glue trough 111 to the mixing bin 1021 of the chassis 102 under the action of the centrifugal force generated when the fiber decomposition and gluing unit 101 rotates, and then be evenly and fully mixed with the broken fibers.
[0050] It can be seen that, by designing the defibrination and gluing unit 101, glue powder can be added through the hollow cavity 141 of the rotating shaft 14, so that when the defibrination and gluing unit 101 rotates, the glue powder is thrown into the cylinder 11 by centrifugal force, so that the glue powder can be dispersed into the cylinder 11, and the glue powder is evenly moved out of the cylinder 11 from the glue dispersing groove 111 of the cylinder 11 to be mixed with the fiber mass, thereby reducing the amount of glue powder applied and saving production costs; and during the rotation of the defibrination and gluing unit 101, the air inlet blade The wheel 12 rotates accordingly to supply air to the interior of the cylinder 11, thereby reducing the temperature inside the chassis 102 of the fiber disintegration and gluing equipment 100 and the temperature of the blade head 22 of the fiber disintegration knife group 2, avoiding fire accidents caused by heat accumulation in the chassis 102, and ensuring production safety. At the same time, the air supply of the air inlet impeller 12 also helps to move the glue powder from the glue dispersing tank 111 into the chassis 102, and can further improve the dispersion of the fiber clusters, so that the glue powder and the broken fibers are evenly and fully mixed.
[0051] Multiple groups of flow-disrupting units 15 are distributed along the axial direction of the cylinder 11, and the flow-disrupting units 15 are located inside the cylinder 11. The flow-disrupting units 15 include two or more flow-disrupting plates 151, which are distributed along the circumference of the rotating shaft 14 and are fixedly connected to the rotating shaft 14. The flow-disrupting units 15 can perform a secondary dispersion on the rubber powder dispersed into the cylinder 11, and cooperate with the air supplied by the air inlet impeller 12 to better move the rubber powder out of the rubber dispersing tank 111 so as to mix with the dispersed fiber clumps, thereby further improving the mixing uniformity of the rubber powder and the dispersed fibers, thereby better reducing the amount of rubber powder applied while ensuring the strength of the subsequently produced fiberboard remains unchanged, thereby further saving production costs.
[0052] In addition, if Figure 6As shown, the cylinder 11 is formed with a guide plate 113 at each glue dispensing groove 111. The guide plate 113 extends axially along the cylinder 11. Preferably, in the axial direction of the cylinder 11, the length of the guide plate 113 is equal to the length of the glue dispensing groove 111. In the rotation direction R of the defiberizing and gluing unit 101, the guide plate 113 extends obliquely from the upstream end of the glue dispensing groove 111 toward the downstream end of the glue dispensing groove 111 and obliquely toward the interior of the cylinder 11. The guide plate 113 has a windward surface 1131 and a leeward surface 1132. On the upper side, the windward surface 1131 is located at the downstream end of the leeward surface 1132, and a glue guide channel 1130 is formed between the windward surface 1131 and the leeward surface 1132 of a guide plate 113 located at the downstream end of the windward surface 1131. The guide plate 113 is used to cooperate with the turning direction of the fiber disintegrating and gluing unit 101 and the wind sent in by the air inlet impeller 12 to make the glue powder better move from the inside of the cylinder 11 to the outside of the cylinder 11 through the glue dispersing groove 111 to mix with the broken fibers.
[0053] like Figure 1 and Figure 2 As shown, the chassis 102 is also provided with a vent 1024 that extends through the wall of the chassis 102, connecting the vent 1024 with the mixing chamber 1021. The defiberizing and gluing unit 101 is rotatably disposed within the mixing chamber 1021 about its own rotating shaft 14. The air inlet impeller 12 is docked within the vent 1024, with both ends of the rotating shaft 14 extending outside the chassis 102.
[0054] Preferably, the number of ventilation openings 1024 on the chassis 102 is two or more; correspondingly, the number of fiber disintegration and gluing units 101 is two or more, and the two or more fiber disintegration and gluing units 101 correspond one-to-one with the two or more ventilation openings 1024. In the material transfer direction of the fiber disintegration and gluing device 100, two adjacent fiber disintegration and gluing units 101 preferably rotate toward each other [i.e., the two adjacent fiber disintegration and gluing units 101 rotate in opposite directions (the axial ends of the two adjacent fiber disintegration and gluing units 101 can be arranged 180 degrees apart)], so that the blades of the fiber disintegration knife groups 2 of the two adjacent fiber disintegration and gluing units 101 rotate toward each other. This design allows the fiber clumps to be more thoroughly broken up, thereby improving the dispersion of the broken fibers and allowing the glue powder to be more evenly and thoroughly mixed with the broken fibers.
[0055] In this embodiment, bearing seats 103 are respectively provided at both ends of the rotating shaft 14 extending out of the chassis 102, so that the rotating shaft 14 can rotate more smoothly around its own axis, and a pulley 104 is provided at the second end of the rotating shaft 14, so that the fiber decomposition and gluing equipment 100 can rotate by driving the rotating shaft 14 through a motor with a pulley provided on the motor shaft and a transmission belt.
[0056] The following briefly describes the working process of the fiberizing and sizing device 100:
[0057] First, the fiberizing and gluing device 100 is started, so that the plurality of fiberizing and gluing units 101 of the fiberizing and gluing device 100 are all rotated.
[0058] Next, glue powder is added to the hollow cavity 141 of the rotating shaft 14, so that the glue powder can be evenly dispersed into the mixing chamber 1021 of the chassis 102 through the through hole 142 and the powder dispersing groove under the centrifugal force of the rotating fiber dispersing and gluing unit 101 and the wind sent in by the air inlet impeller 12. Subsequently, fiber clumps can be added to the feed port 1022 of the chassis 102, so that after entering the mixing chamber 1021, the fiber clumps can be broken up by the blade head 22 of the fiber dispersing and gluing unit 101, and the broken fibers are evenly and fully mixed with the glue powder dispersed in the mixing chamber 1021. During the rotation of the fiber dispersing and gluing unit 101, the air inlet impeller 12 draws air into the mixing chamber 1021 through the vents 1024 on the chassis 102, thereby effectively reducing the temperature in the mixing chamber 1021 and the temperature of the blade head 22.
[0059] Then, the mixture of the rubber powder and the broken-up fibers is discharged from the discharge port 1023 of the chassis 102 .
[0060] In summary, it can be seen that the fiber disintegration and gluing equipment 100 is provided with a fiber disintegration and gluing unit 101, so that the fiber disintegration and gluing unit 101 can cool the mixer to avoid fire accidents caused by heat accumulation in the chassis 102, thereby ensuring production safety; at the same time, the fiber disintegration and gluing unit 101 can also cool the blade head 22 of the fiber disintegration knife group 2 during operation, thereby extending the service life of the blade head 22; in addition, the glue powder in the mixing bin 1021 and the broken up fibers can be evenly and fully mixed to reduce the amount of glue powder and reduce production costs; furthermore, since each group of fiber disintegration knives of the fiber disintegration and gluing unit 101 can be replaced individually, the overall service life of the fiber disintegration and gluing unit 101 is effectively extended, and the maintenance and use costs of the fiber disintegration and gluing unit 101 are reduced.
[0061] Fiberboard production system embodiment
[0062] The fiberboard production system includes the fiberizing and gluing device described in the above-mentioned embodiment of the fiberizing and gluing device; preferably, the fiberboard production system may further include a fiber lump feeding device and a conveying device. The fiber lump feeding device is used to feed the fiber lump into the feed port of the chassis of the fiberizing and gluing device, so that the fiber lump is broken up by the fiberizing and gluing unit after entering the mixing chamber of the chassis, and at the same time, the glue powder fed from the hollow cavity of the rotating shaft of the fiberizing and gluing unit can be evenly and fully mixed with the broken-up limiter; the conveying device is used to receive the mixed material containing fiber and glue powder discharged from the discharge port of the chassis and transfer the mixed material to the subsequent equipment for recovery or further processing.
[0063] It can be seen that by setting up the above-mentioned fiber disintegration and gluing equipment, the chassis of the fiber disintegration and gluing equipment and the blade heads of the fiber disintegration knife group can be well cooled during the production process to avoid fire accidents caused by heat accumulation in the chassis, thereby ensuring the safety of production; in addition, it can also ensure that the glue powder and the broken up fibers are evenly and fully mixed during the production process, so that the strength of the produced fiberboard remains unchanged and the amount of glue powder can be better reduced, thereby reducing production costs; furthermore, since each group of fiber disintegration knives can be replaced separately, the overall service life of the fiber disintegration and gluing unit can be effectively extended, and the maintenance and use costs of the fiber disintegration and gluing unit can be reduced.
[0064] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
