Technical Field

[0001] The utility model relates to a plate paving device, more specifically, it relates to a wooden inorganic composite board paving device. Background Art

[0002] Wood inorganic composite board is a kind of board made of wood fiber or wood shavings as raw materials and inorganic cementitious materials as adhesives. It has the advantages of formaldehyde-free, flame retardant, and good water resistance, and has gradually attracted more and more consumers' attention. However, its raw materials have high density and moisture content. Unlike existing particleboards and fiberboards, it is difficult to lay them evenly by conventional mechanical paving or airflow paving. The existing technology has carried out a series of modifications on the artificial board paving equipment, but there are still problems such as the difficulty of evenly dispersing the clumped materials and the long transportation route leading to material aggregation and blockage.

[0003] For example: Chinese patent announcement number CN215202497U, announcement date December 17, 2021, the name of the utility model is a new type of bulk material paving device suitable for processing multifunctional wood boards. The application discloses a wood board paving equipment, including a bulk material device, the bulk material device is composed of six groups of coniferous rollers, and the bulk material device is installed at the upper end of the frame; a paving device, the paving device is composed of three groups, and the three groups of paving devices are all installed on the transportation device at the end; the utility model realizes the full dispersion of bulk materials, the agglomeration of depolymerized materials and other problems, but its material transportation route is too long, which inevitably causes leakage problems and causes material waste, and the paving devices at both ends are prone to material transportation dead corners, causing some materials to accumulate and solidify for a long time, causing blockage. Utility Model Content

[0004] The utility model overcomes the problem of too long material transportation route of existing wood board paving equipment, and provides a wood inorganic composite board paving equipment. This scheme greatly shortens the material transportation path of the wood board paving equipment, avoids or reduces material leakage, and improves work efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: a wood-inorganic composite board paving equipment, including a bulking device, the bulking device including a vibrating screen assembly and a bulking barrel, the vibrating screen assembly and the bulking barrel are arranged in a vertical direction and the vibrating screen assembly is arranged above the bulking barrel, and a bulking roller and a scattering roller are arranged horizontally from top to bottom and rotatably connected in the bulking barrel, and a paving conveying device is also arranged at the bottom of the scattering roller. In this scheme, the vibrating screen assembly and the bulking barrel structure are arranged together, and the bulking roller and the scattering roller are arranged in the bulking barrel, so that the material directly enters the bulking process after passing through the vibrating screen assembly, so that the material transportation path is shortened. At the same time, after passing through the bulking process, the material directly enters the paving conveying device below to form a more uniform material layer. The structure inside the entire device is relatively compact, which greatly shortens the material transportation path of the wood board paving equipment, reduces the leakage of materials during long-distance transportation, and improves work production efficiency.

[0006] Preferably, an elastic member is provided between the vibrating screen assembly and the bulk barrel, and a first driver is provided on the bulk barrel or the vibrating screen assembly. Since the vibrating screen assembly and the bulk barrel are arranged in a vertical relationship, the elastic member can produce an up-and-down shaking effect on the vibrating screen assembly, thereby screening the material in the vibrating screen assembly, and the material falls into the bulk barrel after the screening process. The first driver is used to make the vibrating screen assembly vibrate up and down, and in cooperation with the elastic member, the screening effect of the vibrating screen assembly is better.

[0007] Preferably, the vibrating screen assembly comprises a hopper and a screen disposed in the hopper, and a discharge port is disposed on the side wall of the hopper, and the position of the discharge port is flush with the screen. The hopper is used to put materials, and the screen is used to screen materials and retain the agglomerated materials above the screen, and then the agglomerated material particles are discharged from the discharge port through the vibration of the vibrating screen assembly. In order to enable the material to be discharged smoothly, the position of the discharge port needs to be flush with the position of the screen to prevent the hopper side wall from hindering the discharge of materials.

[0008] Preferably, the bulking roller and the scattering roller are both needle-leaf rollers. The bulking roller and the scattering roller are used to evenly disperse the material screened out by the screen, and the needle-leaf roller is more conducive to the scattering and dispersion of the material.

[0009] Preferably, the bulking roller and the scattering roller are hollow inside. The bulking roller and the scattering roller are hollow inside, which reduces the weight of the whole equipment on the one hand, and makes it easier to drive the bulking roller and the scattering roller to rotate on the other hand, and can also reduce the inertia of the bulking roller and the scattering roller.

[0010] Preferably, the bottom of the bulk material barrel is provided with an inclined material retaining wall, which is arranged obliquely and inclined toward the moving direction of the material spreading conveying device to prevent part of the material from being thrown too far by the throwing roller and causing material leakage.

[0011] Preferably, the material spreading and conveying device is a conveyor belt, and a first bracket is provided at the position of the conveyor belt outside the bulk material barrel, and a thickness-fixing sweeping roller with adjustable height in the vertical direction is rotatably connected to the first bracket. The material is transported by the conveyor belt, and first brackets are provided on both sides of the conveyor belt in the direction of movement to install the thickness-fixing sweeping roller, so as to sweep and level the material on the conveyor belt to make the material more uniform; and the height of the thickness-fixing sweeping roller can also be adjusted to change the thickness of the material swept and leveled.

[0012] Preferably, the thickness-fixing sweeping roller is a triangular roller, and the triangular teeth are distributed along the axial strip of the thickness-fixing sweeping roller, so as to flatten the material on the conveyor belt.

[0013] Preferably, a second bracket is provided on the side of the first bracket away from the bulk material barrel, and a pre-pressing sweeping roller with adjustable vertical height is rotatably connected to the second bracket. The second bracket is located below the first bracket and is used to install the pre-pressing sweeping roller, which can pre-tighten the material.

[0014] Preferably, the pre-pressing sweeping roller is a flat-tooth roller. The surface of the pre-pressing sweeping roller has long flat teeth distributed axially, which can increase the pre-pressing area of ​​the pre-pressing sweeping roller on the material and exert the pre-pressing effect.

[0015] Compared with the prior art, the utility model has the following beneficial effects: (1) The utility model adopts four groups of rollers with different functions, namely, a bulk roller, a scattering roller, a thickness-fixing sweeping roller and a pre-pressing sweeping roller, to achieve the dispersion, scattering, thickness-fixing and leveling of wood composite board materials; (2) The agglomerated material particles are screened out by a vibrating screen to avoid clogging of subsequent distribution equipment, and the screened materials are dispersed and transported by free fall, and there are no dead corners in the conveying process, avoiding the accumulation and solidification of materials, thereby causing the problem of conveying blockage; (3) The bulk roller and the scattering roller adopt needle-blade rollers, which are convenient for the full scattering and dispersion of materials. The thickness-fixing sweeping roller adopts triangular teeth to play a scraping effect.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0021] Example 1: Figure 1 and Figure 2 A wood-based inorganic composite board paving equipment shown in the figure includes a bulk material device and a paving conveying device, wherein the bulk material device is arranged directly above the paving conveying device, wherein the bulk material device includes a vibrating screen assembly and a bulk material barrel 1, wherein the vibrating screen assembly includes a hopper 6 and a screen 7, wherein the hopper 6 is in a square cone shape, with a large mouth facing upward and a conical mouth facing downward, wherein a screen 7 is fixedly connected to the interior of the hopper 6, wherein the screen 7 is arranged horizontally and can screen the material, wherein a horizontal discharge port 8 is provided on a side wall of the hopper 6, wherein the position of the discharge port 8 is flush with that of the screen 7, and the opening is located on the upper side of the screen 7, thereby preventing the side wall of the hopper 6 from obstructing the discharge of the material.

[0022] The bulk material barrel 1 is arranged below the vibrating screen assembly, and an elastic member 4 is provided between the hopper 6 in the vibrating screen assembly and the bulk material barrel 1. Specifically, the elastic member 4 is a telescopic spring structure, and a plurality of spring structures are provided. Specifically, spring fixing plates 15 are fixedly connected below the hopper 6 and above the bulk material barrel 1. The size of the spring fixing plate 15 is slightly larger than the cross-sectional size of the side wall of the hopper 6 and the side wall of the bulk material barrel 1. Both ends of the telescopic spring are fixedly connected to the upper and lower spring fixing plates 15. On the one hand, the connection strength of the telescopic spring is increased, and on the other hand, the hopper 6 is made more stable in the horizontal direction. At least two telescopic springs are arranged along the length direction of the spring fixing plate 15, so that the screening effect of the vibrating screen assembly is more stable. Two motor mounting plates 16 are also provided on the outer wall of the bulk material barrel 1, and the motor mounting plates 16 are fixedly connected to the outer wall of the bulk material barrel 1. A first driver 5 is provided on the two motor mounting plates 16. Specifically, the first driver 5 is a vibration motor, which is used to drive the vibration screen assembly to vibrate up and down in the vertical direction, and cooperate with the elastic effect of the elastic member 4 to make the screening effect of the vibration screen assembly better.

[0023] When the first driver 5 is started, the vibrating screen assembly as a whole vibrates up and down, and with the elastic effect of the elastic member 4, the material produces a vibrating screening effect on the screen 7, and agglomerated materials and particles that are difficult to disperse remain on the screen 7. Under the vibration action of the vibrating screen assembly, the agglomerated materials that are difficult to disperse will also move toward the discharge port 8 on the hopper 6, and be discharged from the hopper 6 and enter the material recovery device (not shown in the figure), thereby completing the material screening work.

[0024] A bulking roller 2 and a scattering roller 3 are arranged in sequence from top to bottom in the bulking barrel 1. The bulking roller 2 and the scattering roller 3 are arranged in parallel, and the installation distance between the bulking roller 2 and the scattering roller 3 is 20 cm to 30 cm. Both ends of the bulking roller 2 and the two ends of the scattering roller 3 are rotatably connected to the side wall of the bulking barrel 1, and the bulking roller 2 and the scattering roller 3 are both located below the screen 7. When the material is screened by the screen 7, it directly falls into the position of the bulking roller 2, and the material is dispersed by the bulking roller 2 to make the material more uniform. After passing through the bulking roller 2, it falls into the position of the scattering roller 3, and the scattering roller 3 can scatter and disperse the material.

[0025] It should be noted that the upper half of the bulk material barrel 1 is in the shape of a right prism (cube), and one side wall of the lower half is inclined to form a material retaining wall 9, which is arranged in a position in the material scattering direction and inclined in the direction of the material paving and conveying device; the bulk material roller 2 is arranged in the cubic structure of the upper half of the bulk material barrel 1, and the scattering roller 3 is arranged in the lower half of the bulk material barrel 1. When the material falls into the scattering roller 3, the material retaining wall 9 can prevent part of the material from being thrown too far by the scattering roller 3 and causing leakage.

[0026] The inside of the bulking roller 2 and the scattering roller 3 are both cylindrical hollow structures, so that the overall mass of the bulking roller 2 and the scattering roller 3 is lighter, the inertia effect is smaller, and the bulking roller 2 and the scattering roller 3 are easier to drive, which reduces the energy consumption of the equipment. A bulking roller drive motor 17 and a scattering roller drive motor 18 are respectively arranged at the positions corresponding to the bulking roller 2 and the scattering roller 3 on the outside of the bulking barrel 1. The bulking roller drive motor 17 and the scattering roller drive motor 18 are respectively arranged on two mounting seats 19 fixed on the outer wall of the bulking barrel 1. At the same time, an equipment bracket 20 is also arranged at the bottom of the mounting seat 19 of the scattering roller drive motor 18. The equipment bracket 20 surrounds the periphery of the bulking barrel 1 and is used to support and fix the bulking device as a whole.

[0027] Both the bulk material roller 2 and the scattering roller 3 are needle-shaped rollers, that is, needle columns 21 are arranged on the outer surfaces of the bulk material roller 2 and the scattering roller 3, and the needle columns 21 are vertically fixed to the outer surfaces of the bulk material roller 2 and the scattering roller 3 along the radial direction of the bulk material roller 2 and the scattering roller 3, and eight rows of needle columns 21 are distributed axially of the bulk material roller 2 and the scattering roller 3. The needle column 21 structure on the bulk material roller 2 and the needle column 21 structure on the scattering roller 3 are staggered, which is more conducive to the dispersion of the material and makes the material more evenly distributed.

[0028] A material spreading and conveying device is provided below the scattering roller 3, that is, below the bulk material barrel 1. Specifically, the material spreading and conveying device adopts a conveyor belt 10 structure, which is mainly used to convey dispersed materials. After passing through the bulk material roller 2 and the scattering roller 3, the materials can be evenly distributed on the conveyor belt 10. The width of the conveyor belt 10 is slightly larger than the width of the bulk material barrel 1 to prevent the materials from leaking from the edge of the conveyor belt 10. In addition, it should be noted that the movement direction of the conveyor belt 10 is toward the location of the material retaining wall 9. At the same time, the movement direction of the conveyor belt 10 is opposite to the movement direction of the bottom of the scattering roller 3, that is, as shown in FIG. Figure 1 As shown, the blocking wall 9 is located on the right side of the bulk barrel 1, the transmission direction of the conveyor belt 10 is rightward, and the rotation direction of the scattering roller 3 is clockwise, so that the movement direction of the bottom of the scattering roller 3 is leftward. This is more conducive to the dispersion of materials on the conveyor belt 10.

[0029] A first bracket 11 and a second bracket 13 are also provided on both sides of the conveyor belt 10. The first bracket 11 and the second bracket 13 are both provided on the outside of the bulk barrel 1, and the first bracket 11 is closer to the bulk barrel 1 than the second bracket 13. A thickness-fixing sweeping roller 12 and a pre-pressing sweeping roller 14 are rotatably connected to the first bracket 11 and the second bracket 13 respectively. The thickness-fixing sweeping roller 12 is used to limit the thickness of the material on the conveyor belt 10, and the pre-pressing sweeping roller 14 is used to pre-press the material of the fixed thickness. The surface of the thickness-fixing sweeping roller 12 is provided with a triangular rack distributed along the axial direction of the thickness-fixing sweeping roller 12. The triangular rack can play a role in scraping and leveling the material on the conveyor belt 10, so that the material is relatively flat on the conveyor belt 10, and the long triangular rack can cover the width of the conveyor belt 10 in the entire range; and the surface of the pre-pressing sweeping roller 14 is provided with a flat rack (trapezoidal rack) distributed along the axial direction of the pre-pressing sweeping roller 14. The flat tooth structure can increase the contact area with the material on the conveyor belt 10 and improve the pre-pressing effect.

[0030] It should be noted that the height of the thickness-fixing sweeping roller 12 and the pre-pressing sweeping roller 14 can be adjusted. Specifically, the first bracket 11 and the second bracket 13 can be designed as liftable brackets, and the drive motor of the thickness-fixing sweeping roller 12 (not shown in the figure) and the drive motor of the pre-pressing sweeping roller 14 (not shown in the figure) are respectively arranged in the upper part of the first bracket 11 and the second bracket 13, and are aligned with the two roller shafts. In this way, when the height of the first bracket 11 and the second bracket 13 is adjusted, it will not affect the rotation of the thickness-fixing sweeping roller 12 and the pre-pressing sweeping roller 14, and can work normally.

[0031] It should also be noted that the flat tooth structure at the bottom of the pre-pressing sweeping roller 14 is slightly lower than the triangular teeth at the bottom of the thickness-fixing sweeping roller 12. The above requirements can be met by adjusting the height of the first bracket 11 and the second bracket 13. After the thickness-fixing sweeping roller 12 limits the material thickness on the conveyor belt 10, the material is not compacted and remains in a fluffy state. The flat teeth at the bottom of the pre-pressing sweeping roller 14 are slightly lower, which can produce a pre-pressing effect on the fluffy material.

[0032] Example 2: Figure 2 and Figure 3 A wood-based inorganic composite board paving equipment shown in the figure includes a bulk material device and a paving conveying device, wherein the bulk material device is arranged directly above the paving conveying device, wherein the bulk material device includes a vibrating screen assembly and a bulk material barrel 1, wherein the vibrating screen assembly includes a hopper 6 and a screen 7, wherein the hopper 6 is in a square cone shape, with a large mouth facing upward and a conical mouth facing downward, wherein a screen 7 is fixedly connected to the interior of the hopper 6, wherein the screen 7 is arranged horizontally and can screen the material, wherein a horizontal discharge port 8 is provided on a side wall of the hopper 6, wherein the position of the discharge port 8 is flush with that of the screen 7, and the opening is located on the upper side of the screen 7, thereby preventing the side wall of the hopper 6 from obstructing the discharge of the material.

[0033] The bulk material barrel 1 is arranged below the vibrating screen assembly, and an elastic member 4 is provided between the hopper 6 in the vibrating screen assembly and the bulk material barrel 1. Specifically, the elastic member 4 is a telescopic spring structure, and a plurality of spring structures are provided. Specifically, spring fixing plates 15 are fixedly connected below the hopper 6 and above the bulk material barrel 1. The size of the spring fixing plate 15 is slightly larger than the cross-sectional size of the side wall of the hopper 6 and the side wall of the bulk material barrel 1. Both ends of the telescopic spring are fixedly connected to the upper and lower spring fixing plates 15. On the one hand, the connection strength of the telescopic spring is increased, and on the other hand, the hopper 6 is made more stable in the horizontal direction. At least two telescopic springs are arranged along the length direction of the spring fixing plate 15, so that the screening effect of the vibrating screen assembly is more stable. Two motor mounting plates 16 are also provided on the outer wall of the bulk material barrel 1, and the motor mounting plates 16 are fixedly connected to the outer wall of the bulk material barrel 1. A first driver 5 is provided on the two motor mounting plates 16. Specifically, the first driver 5 is a vibration motor, which is used to drive the vibration screen assembly to vibrate up and down in the vertical direction, and cooperate with the elastic effect of the elastic member 4 to make the screening effect of the vibration screen assembly better.

[0034] When the first driver 5 is started, the vibrating screen assembly as a whole vibrates up and down, and with the elastic effect of the elastic member 4, the material produces a vibrating screening effect on the screen 7, and agglomerated materials and particles that are difficult to disperse remain on the screen 7. Under the vibration action of the vibrating screen assembly, the agglomerated materials that are difficult to disperse will also move toward the discharge port 8 on the hopper 6, and be discharged from the hopper 6 and enter the material recovery device (not shown in the figure), thereby completing the material screening work.

[0035] In this embodiment, the screen 4 can be provided with two layers to improve the screening effect. Correspondingly, the discharge opening 8 is also provided with two layers, and is aligned with the positions of the two layers of screen 7 respectively.

[0036] A bulking roller 2 and two scattering rollers 3 are arranged in order from top to bottom in the bulking barrel 1. The bulking roller 2 and the two scattering rollers 3 are arranged in parallel, and the installation distance between the bulking roller 2 and the scattering roller 3 in the vertical direction is 20 cm to 30 cm, and the distance between the two scattering rollers 3 is set to 10 cm to 20 cm. The overall size of the scattering roller 3 is smaller than the overall size of the bulking roller 2. Both ends of the bulking roller 2 and the two ends of the scattering roller 3 are rotatably connected to the side wall of the bulking barrel 1, and the bulking roller 2 and the scattering roller 3 are both located below the screen 7. After the material is screened by the screen 7, it directly falls into the position of the bulking roller 2, and the material is dispersed by the bulking roller 2 to make the material more uniform. After passing through the bulking roller 2, it falls into the position of the two scattering rollers 3, and the scattering rollers 3 can scatter and disperse the material. Among them, the two scattering rollers 3 can scatter the material more evenly, so that the material is more evenly distributed on the conveyor belt 10.

[0037] It should be noted that the upper half of the bulk material barrel 1 is in the shape of a right prism (cube), and one side wall of the lower half is inclined to form a material retaining wall 9, which is arranged in a position in the material scattering direction and inclined in the direction of the material paving and conveying device; the bulk material roller 2 is arranged in the cubic structure of the upper half of the bulk material barrel 1, and the two scattering rollers 3 are arranged in the lower half of the bulk material barrel 1. When the material falls into the scattering roller 3, the material retaining wall 9 can prevent part of the material from being thrown too far by the scattering roller 3 and causing leakage.

[0038] The inside of the bulking roller 2 and the scattering roller 3 are both cylindrical hollow structures, so that the overall mass of the bulking roller 2 and the scattering roller 3 is lighter, the inertia effect is smaller, and the bulking roller 2 and the scattering roller 3 are easier to drive, which reduces the energy consumption of the equipment. A bulking roller drive motor 17 and a scattering roller drive motor 18 are respectively arranged at the positions corresponding to the bulking roller 2 and the scattering roller 3 on the outside of the bulking barrel 1. The bulking roller drive motor 17 and the scattering roller drive motor 18 are respectively arranged on two mounting seats 19 fixed on the outer wall of the bulking barrel 1. At the same time, an equipment bracket 20 is also arranged at the bottom of the mounting seat 19 of the scattering roller drive motor 18. The equipment bracket 20 surrounds the periphery of the bulking barrel 1 and is used to support and fix the bulking device as a whole.

[0039] Both the bulk material roller 2 and the scattering roller 3 are needle-shaped rollers, that is, needle columns 21 are arranged on the outer surfaces of the bulk material roller 2 and the scattering roller 3, and the needle columns 21 are vertically fixed to the outer surfaces of the bulk material roller 2 and the scattering roller 3 along the radial direction of the bulk material roller 2 and the scattering roller 3, and eight rows of needle columns 21 are distributed axially of the bulk material roller 2 and the scattering roller 3. The needle column 21 structure on the bulk material roller 2 and the needle column 21 structure on the scattering roller 3 are staggered, which is more conducive to the dispersion of the material and makes the material more evenly distributed.

[0040] A material spreading and conveying device is provided below the scattering roller 3, that is, below the bulk material barrel 1. Specifically, the material spreading and conveying device adopts a conveyor belt 10 structure, which is mainly used to convey dispersed materials. After passing through the bulk material roller 2 and the scattering roller 3, the materials can be evenly distributed on the conveyor belt 10. The width of the conveyor belt 10 is slightly larger than the width of the bulk material barrel 1 to prevent the materials from leaking from the edge of the conveyor belt 10. In addition, it should be noted that the movement direction of the conveyor belt 10 is toward the location of the material retaining wall 9. At the same time, the movement direction of the conveyor belt 10 is opposite to the movement direction of the bottom of the scattering roller 3, that is, as shown in FIG. Figure 1 As shown, the blocking wall 9 is located on the right side of the bulk barrel 1, the transmission direction of the conveyor belt 10 is rightward, and the rotation direction of the scattering roller 3 is clockwise, so that the movement direction of the bottom of the scattering roller 3 is leftward. This is more conducive to the dispersion of materials on the conveyor belt 10.

[0041] A first bracket 11 and a second bracket 13 are also provided on both sides of the conveyor belt 10. The first bracket 11 and the second bracket 13 are both provided on the outside of the bulk barrel 1, and the first bracket 11 is closer to the bulk barrel 1 than the second bracket 13. A thickness-fixing sweeping roller 12 and a pre-pressing sweeping roller 14 are rotatably connected to the first bracket 11 and the second bracket 13 respectively. The thickness-fixing sweeping roller 12 is used to limit the thickness of the material on the conveyor belt 10, and the pre-pressing sweeping roller 14 is used to pre-press the material of the fixed thickness. The surface of the thickness-fixing sweeping roller 12 is provided with a triangular rack distributed along the axial direction of the thickness-fixing sweeping roller 12.

[0042] It should be noted that the height of the thickness-fixing sweeping roller 12 and the pre-pressing sweeping roller 14 can be adjusted. Specifically, the first bracket 11 and the second bracket 13 can be designed as liftable brackets, and the drive motor of the thickness-fixing sweeping roller 12 (not shown in the figure) and the drive motor of the pre-pressing sweeping roller 14 (not shown in the figure) are respectively arranged in the upper part of the first bracket 11 and the second bracket 13, and are aligned with the two roller shafts. In this way, when the height of the first bracket 11 and the second bracket 13 is adjusted, it will not affect the rotation of the thickness-fixing sweeping roller 12 and the pre-pressing sweeping roller 14, and can work normally.

[0043] It should also be noted that the flat tooth structure at the bottom of the pre-pressing sweeping roller 14 is slightly lower than the triangular teeth at the bottom of the thickness-fixing sweeping roller 12. The above requirements can be met by adjusting the height of the first bracket 11 and the second bracket 13. After the thickness-fixing sweeping roller 12 limits the material thickness on the conveyor belt 10, the material is not compacted and remains in a fluffy state. The flat teeth at the bottom of the pre-pressing sweeping roller 14 are slightly lower, which can produce a pre-pressing effect on the fluffy material.
