Description

Technical Field

[0001] This invention relates to the field of particleboard production equipment technology, specifically to a grid-adding device for particleboard production. Background Technology

[0002] Particleboard, also known as chipboard, is a type of engineered wood product made by cutting various branches, small-diameter timber, fast-growing wood, and wood chips into fragments of a certain size, drying them, mixing them with adhesives, hardeners, and waterproofing agents, and then pressing them under specific temperature and pressure. The particles are unevenly arranged. Although particleboard is called chipboard, it is not the same as solid wood particleboard. Solid wood particleboard only has a similar processing method to particleboard, but its quality is far superior.

[0003] In the production of particleboard, a crucial step is mixing the wood chips and adhesive. The mixed material is then conveyed and added to the laying equipment to form a lattice pattern on the surface of the board. However, under current technological conditions, the mixing process of wood chips and adhesive has significant shortcomings.

[0004] From the perspective of the physical structure of wood shavings, they are typically irregular, thin flakes cut from wood. These flakes have a certain thickness, and their surfaces are not completely smooth; instead, they contain many tiny bumps, textures, and fibrous structures. These microstructures give the shavings a certain roughness, but also create a complex physical barrier. When glue comes into contact with shavings, it initially adheres to the surface due to these tiny bumps and textures. However, the tightly packed and interwoven fibrous structure inside the shavings creates a barrier-like effect. Glue molecules are hindered by these fibrous structures when attempting to penetrate the shavings. The gaps between the fibers vary in size, and some gaps may be too narrow for glue molecules to pass through smoothly. Simultaneously, the texture and bumps on the shavings surface also cause uneven glue distribution, with glue accumulating in some areas and failing to reach others.

[0005] Furthermore, during the cutting process, wood shavings may contain tiny pores and channels within them. However, these pores and channels are not evenly distributed and vary in size and shape. As the glue flows, it is difficult for it to penetrate evenly into the wood shavings along these irregular channels. Moreover, wood shavings may agglomerate to some extent during mixing, with multiple shavings sticking together, further increasing the difficulty of glue penetration. This often results in the glue remaining only on the surface of the shaving clump, unable to penetrate deeply and make full contact with each individual shaving.

[0006] The inability of the adhesive to effectively penetrate the wood chips results in a limited contact area between the chips and the adhesive, leading to a low degree of mixing and consequently affecting the overall bonding strength and physical properties of the particleboard. This insufficient mixing not only may cause quality problems such as delamination and cracking during use, but also limits the development of particleboard in high-end applications, failing to meet the market's growing demand for high-quality engineered wood products. Therefore, to improve the mixing degree of wood chips and adhesive, this application provides a grid-addition device for particleboard production. Summary of the Invention

[0007] The purpose of this invention is to provide a grid-adding device for particleboard production to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A grid-adding device for particleboard production, comprising:

[0010] The feeding bin and the first mixing bin are connected through to the lower end of the feeding bin. The first mixing bin is open at one end away from the feeding bin and is fixedly connected to a first fixing plate.

[0011] Multiple support columns are horizontally fixed to the first fixed plate. The ends of the multiple support columns away from the first fixed plate are jointly fixed to a second fixed plate. A second mixing chamber is fixed to the end face of the second fixed plate. The second mixing chamber is coaxial with the first mixing chamber. An extrusion chamber is coaxially fixed to the end of the second mixing chamber away from the second fixed plate. A feeding pipe is connected through the end of the extrusion chamber away from the second mixing chamber. A conveying unit is installed in both the first mixing chamber and the second mixing chamber.

[0012] A receiving unit is provided between the first fixed plate and the second fixed plate, and a deformation unit for driving the receiving unit to deform is provided between the first fixed plate and the second fixed plate.

[0013] Furthermore, the receiving unit includes an adhesive tank fixed to the opposite sides of the first fixed plate and the second fixed plate. The number and position of the plurality of adhesive tanks correspond to the plurality of support columns. The interior of the adhesive tank is used to store adhesive. The two ends of the adhesive tank are respectively connected to the first fixed plate and the second fixed plate. A plurality of arc-shaped plates are also provided between the first fixed plate and the second fixed plate. The arc-shaped plates are engaged between two adjacent adhesive tanks, and the plurality of arc-shaped plates form a receiving cavity.

[0014] Furthermore, the deformation unit includes a rotating shaft that is horizontally rotatably connected to the first fixed disk and the second fixed disk. The number and position of the rotating shafts correspond to the support column. Multiple rotating shafts are connected by a transmission unit. A swing arm is integrally formed and fixed to the periphery of the rotating shaft. The swing arm is rotatably connected to a hinge rod. The end of the hinge rod away from the swing arm is hinged to the arc plate.

[0015] Furthermore, the transmission unit includes a synchronous pulley fixedly sleeved on one end of the rotating shaft, and a synchronous belt is wound around a plurality of the synchronous pulleys. One of the rotating shafts is driven to rotate by a servo motor mounted on the second fixed disk.

[0016] Furthermore, the first fixed plate and the second fixed plate each have multiple lugs fixed to their opposite surfaces, the outer edge of the arc plate is fixed to a guide post, and the lugs have through holes for the guide post to pass through freely.

[0017] Furthermore, the glue tank has an adhesive outlet on the outer wall of one side facing the radial inner side of the first mixing tank, the adhesive outlet communicating with the inner cavity of the glue tank, and the outer wall of the glue tank has an adhesive inlet.

[0018] Furthermore, an inlet tube is installed on the glue inlet, and an adjusting seat is fixedly connected to the glue inlet tube. The adjusting seat is hollow inside and communicates with the glue inlet. An interface is fixedly connected to the periphery of the adjusting seat, and the interface communicates with the inner cavity of the adjusting seat. An adjusting unit is provided inside the adjusting seat.

[0019] Furthermore, the adjustment unit includes a sliding part coaxially engaged with the inner cavity of the adjustment seat. A connecting hole is provided around the periphery of the sliding part. A drive rod is coaxially fixed to the sliding part. The drive rod slides out of the adjustment seat. A ball is rotatably embedded at the end of the drive rod away from the adjustment seat. A first gear is fixedly sleeved around the periphery of the rotating shaft. A second gear is rotatably sleeved around the periphery of the support column. The second gear meshes externally with the first gear. A rotating part is coaxially fixed to the end face of the second gear. A lever is fixedly attached around the periphery of the rotating part. The lever works in conjunction with the ball.

[0020] Furthermore, a stop ring is fixedly sleeved on one end of the drive rod that protrudes from the adjustment seat, and a spring is wrapped around the periphery of the drive rod. The two ends of the spring in the direction of its elastic force elastically abut against the stop ring and the outer wall of the adjustment seat, respectively.

[0021] Furthermore, the conveying unit includes a drive motor installed at the end of the first mixing chamber, and a spiral auger is provided in both the first and second mixing chambers, the spiral auger being driven connected to the motor shaft of the drive motor.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, by deforming the receiving unit, the wood shavings and glue can be fully mixed in the deformed receiving unit, and the glue can enter the interior of the wood shavings to improve the degree of mixing with the wood shavings. The mixed glue is transported to the extrusion chamber by the conveying unit, and the extrusion chamber extrudes the wood shavings after mixing with glue to further improve the degree of mixing between glue and wood shavings.

[0024] 2. In this invention, the rotating shaft rotates, causing the swing arm to drive the hinge rod to swing. When the hinge rod swings, it drives the arc plate to move radially along the first mixing chamber or the second mixing chamber, so that multiple arc plates are in a state of moving closer or further away from each other. This allows the internal volume of the receiving cavity formed by the multiple arc plates and the glue chamber to be adjusted. When the wood shavings are transported into the receiving cavity, the internal volume of the receiving cavity increases, and the wood shavings become loose, allowing the glue to enter the wood shavings. Then, the internal volume of the receiving cavity decreases, thereby squeezing the wood shavings and squeezing the glue, allowing the glue to penetrate into the wood shavings, so that the glue and wood shavings can be mixed better, and the degree of contact between the glue and wood shavings can be improved.

[0025] 3. In this invention, the rotation of the shaft causes the first gear and the second gear to mesh and drive the rotating part to rotate. When the rotating part rotates, the paddle block contacts the ball bearing and the drive rod moves away from the shaft. This causes the sliding part to slide in the inner cavity of the adjusting seat, increasing the overlap area between the connecting hole and the glue inlet and the interface. As the arc-shaped plates move away from each other, the flow rate of glue into the glue tank increases, so that when the wood shavings are in a loose state, the glue can quickly enter the wood shavings for mixing.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-10The present invention provides a lattice-adding device for particleboard production, comprising a feeding bin 1, a first mixing bin 2 horizontally connected to the lower end of the feeding bin 1, a first fixed plate 6 coaxially fixed to the end of the first mixing bin 2 away from the feeding bin 1, four support columns 15 horizontally fixed to the end face of the first fixed plate 6, a second fixed plate 13 fixed to the end face of the support column 15 away from the first fixed plate 6, the first fixed plate 6 and the second fixed plate 13 being coaxial, and a second mixing bin 11 coaxially fixed to the end face of the second fixed plate 13. The first mixing bin 2 and the second mixing bin 11 are coaxial, and the first mixing bin 2 and the second mixing bin 11 can be reliably connected together by the support of the four support columns 15.

[0039] The second mixing chamber 11 is coaxially fixed to an extrusion chamber 10 at the end away from the second fixed plate 13. The outer diameter of the extrusion chamber 10 increases sequentially towards the second mixing chamber 11. The end of the extrusion chamber 10 away from the second mixing chamber 11 is connected to a feeding pipe 9. The lower end of the feeding pipe 9 is connected to an external lattice paving device. A drive motor 3 is installed at the end of the first mixing chamber 2. The first mixing chamber 2 and the second mixing chamber 11 are both equipped with a spiral auger 28. The spiral auger 28 is driven by the motor shaft of the drive motor 3.

[0040] Four glue tanks 16 are fixedly connected to the opposing surfaces of the first fixed plate 6 and the second fixed plate 13. The number and position of the four glue tanks 16 correspond to the four support columns 15, and the four glue tanks 16 are arranged in an array along the axial direction of the first fixed plate 6. The glue tanks 16 are used to store glue. The two ends of the glue tanks 16 respectively abut against the first fixed plate 6 and the second fixed plate 13. Four arc-shaped plates 4 are also provided between the first fixed plate 6 and the second fixed plate 13. The arc-shaped plates 4 are engaged between two adjacent glue tanks 16, and the four arc-shaped plates 4 form a receiving cavity. Specifically, after the four arc-shaped plates 4 move into place in the radially inward direction of the first mixing chamber 2, the gap between the four arc-shaped plates 4 will be filled by the narrower end of the glue tank 16, so that the four arc-shaped plates 4 form a receiving cavity. The inner diameter of the receiving cavity is slightly smaller than the inner diameter of the first mixing chamber 2.

[0041] The above structure, through the deformation of the receiving unit, allows the wood shavings and glue to be fully mixed within the deformed receiving unit. The glue can penetrate into the wood shavings, improving the degree of mixing with them. The mixed glue is then conveyed to the extrusion chamber via the conveying unit, where the extrusion chamber extrudes the glue-mixed wood shavings, further improving the degree of mixing between the glue and wood shavings.

[0042] The first fixed plate 6 and the second fixed plate 13 are connected horizontally to four rotating shafts 14 by mounting bearings. The number and position of the rotating shafts 14 correspond to the support column 15. A swing arm 18 is integrally formed and fixed to the periphery of the rotating shaft 14. The swing arm 18 is rotatably connected to a hinge rod 17. The end of the hinge rod 17 away from the swing arm 18 is hinged to the arc plate 4. One end of the rotating shaft 14 passes through the first fixed plate 6 and is fixedly sleeved with a synchronous pulley. A synchronous belt is wound around the four synchronous pulleys. One of the rotating shafts 14 is driven to rotate by a servo motor 12 mounted on the second fixed plate 13. The servo motor 12 starts and drives one of the synchronous pulleys to rotate. Through the transmission of the synchronous belt, the four synchronous pulleys can rotate synchronously and drive the four rotating shafts 14 to rotate.

[0043] Multiple lugs 21 are fixed to the opposite surfaces of the first fixed plate 6 and the second fixed plate 13. A guide post 20 is fixed to the outer edge of the arc plate 4. The lugs 21 have through holes for the guide post 20 to pass through freely. The guide post 20 slides in the through holes, thereby guiding and limiting the arc plate 4 when it moves radially along the first mixing chamber 2. The rotating shaft causes the swing arm to swing the hinge rod. When the hinge rod swings, it drives the arc plate to move radially along the first or second mixing chamber, causing multiple arc plates to move closer or further apart. This allows the internal volume of the receiving cavity formed by the multiple arc plates and the glue chamber to be adjusted. When the wood shavings are conveyed into the receiving cavity, the internal volume of the receiving cavity increases, causing the wood shavings to become loose, allowing the glue to enter the wood shavings. Then, the internal volume of the receiving cavity decreases, which in turn compresses the wood shavings, causing the wood shavings to compress the glue, allowing the glue to penetrate into the wood shavings, so that the glue and wood shavings can be mixed better and the contact between the glue and wood shavings can be improved.

[0044] The glue tank 16 has a glue outlet 5 on its outer wall facing the radially inner side of the first mixing tank 2. The glue outlet 5 communicates with the inner cavity of the glue tank 16. The outer wall of the glue tank 16 has a glue inlet 27. A glue inlet pipe 26 is installed on the glue inlet 27. An adjusting seat 7 is fixedly connected to the glue inlet pipe 26. The adjusting seat 7 is hollow and communicates with the glue inlet 27. An interface 29 is fixedly connected to the periphery of the adjusting seat 7. The interface 29 communicates with the inner cavity of the adjusting seat 7. A cylindrical sliding part 32 is coaxially engaged in the inner cavity of the adjusting seat 7. A connecting hole 33 is opened on the periphery of the sliding part 32. A drive rod 8 is coaxially fixedly connected to the sliding part 32. The drive rod 8 slides through the adjusting part 32. The end of the drive rod 8 away from the adjusting seat 7 is rotatably fitted with a ball bearing 31. The first gear 19 is fixedly sleeved around the circumference of the rotating shaft 14. The second gear 22 is rotatably sleeved around the circumference of the support column 15. The second gear 22 meshes externally with the first gear 19, and a rotating part 23 is coaxially fixed to the end face of the second gear 22. A lever 24 is fixedly sleeved around the circumference of the rotating part 23. The lever 24 works in conjunction with the ball bearing 31. A stop ring 30 is fixedly sleeved at the end of the drive rod 8 that protrudes from the adjusting seat 7. A spring 25 is wrapped around the circumference of the drive rod 8. The two ends of the spring 25 elastically abut against the stop ring 30 and the outer wall of the adjusting seat 7, respectively. The rotation of the shaft causes the first and second gears to mesh and drive the rotating part to rotate. When the rotating part rotates, the paddle block contacts the ball bearing and the drive rod moves away from the shaft. This causes the sliding part to slide in the inner cavity of the adjusting seat, increasing the overlap area between the connecting hole and the glue inlet and interface. As the curved plates move away from each other, the flow rate of glue into the glue tank increases, so that when the wood shavings are in a loose state, the glue can quickly enter the wood shavings for mixing.

[0045] The working principle of this embodiment is as follows: the wood shavings in the feeding bin 1 fall into the first mixing bin 2, and then the drive motor 3 starts and drives the spiral auger 28 to rotate, so that the spiral auger 28 transports the wood shavings in the first mixing bin 2 to the receiving cavity surrounded by four arc plates 4. The servo motor 12 starts and drives the four rotating shafts 14 to rotate. When the rotating shafts 14 rotate, the swing arm 18 drives the arc plate 4 to move radially along the first mixing bin 2, so that the arc plate 4 slides between two adjacent glue bins 16. This increases the internal capacity of the receiving cavity, so that the wood shavings are in a loose state after entering the receiving cavity.

[0046] An external glue delivery pump delivers glue to interface 29, then from interface 29 into adjusting seat 7, then through connecting hole 33 into glue inlet 27, and then from glue inlet 27 into glue tank 16. The glue then enters the wood shavings through glue outlet 5, allowing the glue and wood shavings to mix. When the arc plate 4 moves radially outward toward the first mixing tank 2, the rotation of the shaft 14 causes the first gear 19 and the second gear 22 to mesh, and causes the rotating part 23 to rotate. When the rotating part 23 rotates, the paddle block 24 abuts against the ball 31, and the ball 31 squeezes the drive rod 8, causing the drive rod 8 to drive the sliding part 32 to slide in the inner cavity of adjusting seat 7. This increases the overlap area between the opening of connecting hole 33 and the openings of glue inlet 27 and interface 29, thereby increasing the flow rate of glue entering adjusting seat 7 and making the glue and wood shavings mix more thoroughly.

[0047] As the shaft 14 continues to rotate, the arc plate 4 moves in the opposite direction, reducing the internal capacity of the cavity formed by the arc plates 4. This allows for the compression of the wood shavings after mixing with the glue, resulting in a more compact mixture of wood shavings and glue. Then, as conveyed by the auger 28, the wood shavings are transported to the extrusion chamber 10, where the inner wall of the extrusion chamber 10 compresses the wood shavings, further compressing the wood shavings and glue. Finally, the wood shavings fall through the feeding pipe 9 into the external lattice paving equipment.
