Description

Technical Field

[0001] The invention relates to the technical field of particleboard production equipment, in particular to a grid adding device for particleboard production. Background Art

[0002] Particleboard, also known as particle board, is a man-made board made by cutting various branches, small-diameter wood, fast-growing wood, and sawdust into pieces of a certain size. These pieces are then dried, mixed with glue, hardener, and waterproofing agents, and pressed under a certain temperature and pressure. The particles are unevenly arranged. Although particleboard is also called particle board, it is not the same as solid wood particle board. Solid wood particle board uses a similar processing technique, but its quality is far superior to particleboard.

[0003] A key step in particleboard production is mixing the wood chips and glue. This mixture is then conveyed and added to the paving equipment to create the checkered pattern on the board surface. However, existing technology has significant shortcomings in this mixing process.

[0004] Wood shavings, based on their physical structure, are typically irregular, thin flakes formed from wood chips. These flakes are of varying thickness, and their surfaces are not completely smooth, but rather feature numerous microscopic bumps, textures, and fibrous structures. This microstructure imparts a certain degree of roughness to the shavings' surface, while also forming a complex physical barrier. When glue comes into contact with wood shavings, the tiny bumps and textures on the shavings' surface allow the glue to initially adhere to the surface. However, the dense and interwoven fibers within the shavings create a barrier-like effect. These fibers hinder the glue molecules from penetrating the shavings. The gaps between the fibers vary in size, and some gaps may be too narrow for glue molecules to pass through. Furthermore, the texture and bumps on the shavings' surface can lead to uneven glue distribution, resulting in glue accumulation in some areas and difficulty reaching others.

[0005] Furthermore, during the cutting process, the wood shavings may develop tiny pores and channels within them, but these pores and channels are unevenly distributed and vary in size and shape. This makes it difficult for the glue to flow through these irregular channels and evenly penetrate the wood shavings. Furthermore, the wood shavings may aggregate to a certain degree during the mixing process, with multiple shavings clinging together, further complicating the glue's penetration. This often forces the glue to remain on the surface of the shavings, preventing it from penetrating deeply enough to fully contact the individual shavings.

[0006] This difficulty in effectively penetrating the wood particles results in a limited contact area between the wood particles and the glue, resulting in a low degree of mixing, which in turn affects the overall bonding strength and physical properties of the particleboard. This insufficient mixing can not only lead to quality issues such as delamination and cracking during use, but also restrict the development of particleboard in high-end applications, making it impossible to meet the growing market demand for high-quality artificial boards. Therefore, in order to improve the degree of mixing between the wood particles and the glue, the present application provides a grid-adding device for particleboard production.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-10 The present invention provides: a grate adding device for particleboard production, comprising a feeding bin 1, wherein the lower end of the feeding bin 1 is horizontally connected to a first mixing bin 2, the end of the first mixing bin 2 away from the feeding bin 1 is coaxially fixed with a first fixed plate 6, four support columns 15 are horizontally fixed to the end surface of the first fixed plate 6, the end of the support column 15 away from the first fixed plate 6 is fixed to a second fixed plate 13, the first fixed plate 6 and the second fixed plate 13 are coaxial, the end surface of the second fixed plate 13 is coaxially fixed with a second mixing bin 11, the first mixing bin 2 and the second mixing bin 11 are coaxial, and are supported by the four support columns 15, so that the first mixing bin 2 and the second mixing bin 11 can be more firmly connected together; The extrusion bin 10 is coaxially fixed to one end of the second mixing bin 11 away from the second fixed disk 13, and the outer diameter of the extrusion bin 10 increases successively in the direction approaching the second mixing bin 11. The feeding pipe 9 is connected to the end of the extrusion bin 10 away from the second mixing bin 11, and the lower pipe mouth of the feeding pipe 9 is connected to the external lattice paving equipment. A drive motor 3 is installed at the end of the first mixing bin 2, and a spiral auger 28 is provided in the first mixing bin 2 and the second mixing bin 11. The spiral auger 28 is driven and connected to the motor shaft of the drive motor 3.

[0023] Four glue bins 16 are fixedly connected to the opposite surfaces of the first fixed disk 6 and the second fixed disk 13. The number and position of the four glue bins 16 correspond to the four support columns 15, and the four glue bins 16 are arranged in an axial array along the first fixed disk 6. The inside of the glue bin 16 is used to store glue. The two ends of the glue bin 16 are respectively in contact with the first fixed disk 6 and the second fixed disk 13. Four curved plates 4 are also provided between the first fixed disk 6 and the second fixed disk 13. The curved plates 4 are engaged between two adjacent glue bins 16, and a accommodating cavity is formed between the four curved plates 4. Specifically, after the four curved plates 4 move into place in the radial inner direction of the first mixing bin 2, the gaps between the four curved plates 4 will be filled by the narrower ends of the glue bin 16, and the four curved plates 4 will form a accommodating cavity. The inner diameter of the accommodating cavity is slightly smaller than the inner diameter of the first mixing bin 2.

[0024] The above structure deforms the containing unit so that the wood shavings and glue can be fully mixed in the deformed containing 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 bin through the conveying unit, and the extrusion bin extrude the wood shavings mixed with the glue to further improve the degree of mixing of the glue and wood shavings.

[0025] The first fixed plate 6 and the second fixed plate 13 are connected to four rotating shafts 14 for horizontal rotation together through the installation bearings. The number and position of the rotating shafts 14 correspond to the support columns 15. The periphery of the rotating shaft 14 is fixedly connected with a swing arm 18 in an integral manner. The swing arm 18 is rotatably connected with 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 commonly installed around the four synchronous pulleys. One of the rotating shafts 14 is driven to rotate by the servo motor 12 installed on the second fixed plate 13. The servo motor 12 is started, which in turn drives one of the synchronous pulleys to rotate. Then, through the transmission of the synchronous belt, the four synchronous pulleys can rotate synchronously and drive the four rotating shafts 14 to rotate. A plurality of ear blocks 21 are fixedly connected to the opposite surfaces of the first fixed plate 6 and the second fixed plate 13, and a guide column 20 is fixedly connected to the outer edge of the arc plate 4. The ear blocks 21 are provided with through holes for the guide columns 20 to pass freely. The guide columns 20 slide in the through holes, thereby providing guidance and limitation for the arc plate 4 when it moves radially along the first mixing bin 2. By rotating the rotating shaft and causing the swing arm to swing the hinge rod, when the hinge rod swings, it will drive the arc plate to move radially along the first mixing chamber or the second mixing chamber, so that the multiple arc plates are in a moving state of approaching or moving away from each other, thereby making the internal volume of the accommodating cavity surrounded by the multiple arc plates and the glue chamber adjustable. When the wood chips are transported into the accommodating cavity, the wood chips will become loose due to the increase in the internal volume of the accommodating cavity, allowing the glue to enter the wood chips. Then the internal volume of the accommodating cavity is reduced, thereby squeezing the wood chips, causing the wood chips to squeeze the glue, and causing the glue to penetrate into the wood chips, so that the glue and wood chips are better mixed and the contact degree between the glue and wood chips is improved.

[0026] The glue bin 16 is provided with a glue outlet 5 on the outer wall of one side facing the radial inner side of the first mixing bin 2, and the glue outlet 5 is connected to the inner cavity of the glue bin 16. The outer wall of the glue bin 16 is provided with a glue inlet 27, and a glue inlet pipe 26 is installed on the glue inlet 27. The glue inlet pipe 26 is fixedly connected with the adjustment seat 7. The interior of the adjustment seat 7 is hollow and connected with the glue inlet 27. The peripheral edge of the adjustment seat 7 is fixed with an interface 29, which is connected with the inner cavity of the adjustment seat 7. A cylindrical sliding part 32 is coaxially mounted on the inner cavity of the adjustment seat 7. A communicating hole 33 is provided on the peripheral edge of the sliding part 32. The sliding part 32 is coaxially fixed with a driving rod 8, and the driving rod 8 slides out of the adjustment seat 7. The joint seat 7 and the end of the driving rod 8 away from the adjusting seat 7 are rotatably embedded with a ball 31, the periphery of the rotating shaft 14 is fixedly sleeved with a first gear 19, the periphery of the support column 15 is rotatably sleeved with a second gear 22, the second gear 22 is externally meshed with the first gear 19, and the end face of the second gear 22 is coaxially fixed with a rotating part 23, the periphery of the rotating part 23 is fixedly connected with a shift block 24, the shift block 24 is used in conjunction with the ball 31, and the end of the driving rod 8 passing through the adjusting seat 7 is fixedly sleeved with a stop ring 30, and the periphery of the driving rod 8 is wrapped with a spring 25, and the two ends of the spring 25 in the elastic direction elastically press against the stop ring 30 and the outer wall of the adjusting seat 7 respectively. Through the rotation of the rotating shaft, the first gear and the second gear are engaged and transmitted, thereby driving the rotating part to rotate. When the rotating part rotates, the shift block will contact the ball, and the driving rod will move in the direction away from the rotating shaft, thereby causing the sliding part to slide in the inner cavity of the adjustment seat, thereby increasing the overlapping area between the communicating hole and the mouth of the glue inlet and the interface, thereby increasing the flow rate of glue entering the glue bin in the process of the arc plates moving away from each other, so that when the wood chips are in a loose state, the glue can quickly enter the wood chips for mixing.

[0027] 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 is started and drives the spiral auger 28 to rotate, so that the spiral auger 28 conveys the wood shavings in the first mixing bin 2 to the accommodating chamber surrounded by the four curved plates 4. The servo motor 12 is started and drives the four rotating shafts 14 to rotate. When the rotating shafts 14 rotate, the swing arm 18 drives the curved plates 4 to move along the radial direction of the first mixing bin 2, so that the curved plates 4 slide between the two adjacent glue bins 16, thereby increasing the internal capacity of the accommodating chamber and making the wood shavings loose after entering the accommodating chamber. The external glue delivery pump delivers glue to the interface 29, and then enters the adjustment seat 7 through the interface 29, and then enters the glue inlet 27 through the connecting hole 33, and then enters the glue bin 16 through the glue inlet 27. The glue then enters the wood shavings through the glue outlet 5, so that the glue and wood shavings are mixed. When the curved plate 4 moves in the radially outer direction of the first mixing bin 2, the rotation of the rotating shaft 14 will cause the first gear 19 and the second gear 22 to engage, and the rotating part 23 to rotate. When the rotating part 23 rotates, the shift block 24 will press against the ball 31, and the ball 31 will squeeze the driving rod 8, so that the driving rod 8 drives the sliding part 32 to slide in the inner cavity of the adjustment seat 7, so that the overlapping area between the mouth of the connecting hole 33 and the mouths of the glue inlet 27 and the interface 29 is increased, thereby increasing the flow rate of glue entering the adjustment seat 7, so that the glue and wood shavings are mixed to a greater extent; The rotating shaft 14 continues to rotate, which will cause the curved plate 4 to move in the opposite direction, so that the internal capacity of the accommodating cavity surrounded by the curved plates 4 is reduced, thereby being able to squeeze the wood chips mixed with glue, so that the wood chips and glue are mixed more tightly, and then with the conveying of the spiral auger 28, the wood chips are transported to the squeezing bin 10, and the inner wall of the squeezing bin 10 squeezes the wood chips, so that the wood chips and glue are mixed more tightly, and then fall into the external grid paving equipment through the feeding pipe 9.
