Description

Technical Field

[0001] The present invention relates to the technical field of particle board processing, and specifically to a particle board paving device with uniform paving. Background Technique

[0002] Particle board, also known as bagasse board or chipboard, is a kind of artificial board made of wood or other lignocellulosic materials. After applying adhesives, it is glued under the action of heat and pressure. The structure of particle board is relatively uniform, with good processing performance, and can be processed into large-size boards according to needs. Its main characteristics include: uniform structure: The structure of particle board is relatively uniform, which is beneficial to processing. Good processing performance: It can be processed into boards of different specifications and styles according to needs. Good sound absorption and sound insulation performance: It has good sound absorption and sound insulation effects. Rough edges: The edges are prone to moisture absorption, so the edge sealing process is very important. Larger density: Compared with other boards, furniture made of particle board is heavier.

[0003] After retrieval, a continuous paving device for plain boards used in the production of formaldehyde-free and flame-retardant particle boards, disclosed in Chinese Patent Publication No. CN218802930U, includes a conveying frame and a film frame. A conveyor belt is arranged in the conveying groove of the conveying frame, and the film frame is placed on the conveyor belt. By setting a feeding hopper on the conveying frame, the sliding side plates on the left and right sides of the feeding hopper are inserted between the left and right chute grooves of the feeding hopper in a vertical sliding manner. By sliding the sliding side plates, the distance between the bottom of the sliding side plates on the left and right sides of the bottom of the feeding hopper and the conveyor belt can be adjusted, which is convenient for adjusting the paving height of particle boards of different sizes. The sliding side plate on the right side of the feeding hopper can be used as a scraping plate to scrape off excess particles. When the frame at the left end of the mold frame touches the contact plate, the PLC controller controls the opening and closing plate to rotate counterclockwise to close the feeding chute of the feeding hopper, completing the particle paving for one mold frame. This device can achieve continuous paving of multiple particle boards, with good paving effect and uniform feeding.

[0004] In the prior art with the above structure, the particles in the feeding hopper mainly fall into the mold frame from the discharge port by the action of gravity. Due to the physical properties of the particles themselves, such as irregular shape, light texture and certain fluidity, as well as the design limitations of the discharge port of the feeding hopper, when the particles fall from the discharge port, they will show a natural tendency to concentrate. Specifically, a large number of particles will preferentially accumulate in the middle position of the mold frame during the falling process, while the edge area of the mold frame is relatively lacking in particle filling. This uneven accumulation phenomenon gradually intensifies during the movement of the mold frame because the particles at the edge of the mold frame are difficult to be replenished in time like those in the middle position.

[0005] As the paving operation continues, the problem of uneven distribution of wood chips in the formwork frame becomes increasingly serious. The amount of wood chips at the edges of the formwork frame is significantly less than that in the middle position, resulting in significant differences in key performance indicators such as the thickness and density of the finally formed particleboard. This uneven paving of wood chips not only affects the overall quality of the particleboard, making the particleboard prone to quality problems such as warping, deformation, and delamination during subsequent processing and use, reducing the service life and safety of the product; moreover, due to the different requirements for paving uniformity of particleboards of different sizes and specifications, the existing technology is difficult to flexibly adapt to various production needs, resulting in limitations in production efficiency and product quality.

[0006] In addition, the paving equipment of the existing technology also has certain limitations in adjusting the paving height and paving amount. Although the distance between the bottom of the hopper and the conveyor belt can be changed to a certain extent by adjusting the distance between the sliding side plates, thus affecting the paving height, for particleboards of different sizes and specifications, this adjustment method is often difficult to achieve precise control, easily resulting in too much or too little paving amount, further exacerbating the problem of uneven paving of wood chips.

[0007] In summary, the existing plain board continuous paving equipment for the production of formaldehyde-free flame-retardant particleboards has obvious deficiencies in the paving uniformity of wood chips, and it is difficult to meet the requirements of modern wood-based panel industry for high-quality and high-efficiency production. Therefore, it is necessary to improve and innovate the existing technology, and develop a new type of paving equipment that can effectively solve the problem of uneven paving of wood chips, so as to improve the production quality and production efficiency of particleboards and promote the sustainable development of the wood-based panel industry. Summary of the Invention

[0008] The purpose of the present invention is to provide a paving equipment for particleboards with uniform paving to solve the problems proposed in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solutions: A paving equipment for particleboards with uniform paving, comprising: A conveyor for conveying the formwork frame; A frame installed on the top of the conveyor, and a mounting plate is horizontally and fixedly connected to the upper side of the frame; A hopper installed on the top of the mounting plate, and a through groove communicating with the lower opening of the hopper is provided on the surface of the mounting plate; A discharging mechanism rotatably connected to the bottom of the mounting plate, and the discharging mechanism is communicated with the through groove; A discharging cylinder horizontally slidably connected to the discharging mechanism, and a discharging port is provided on the lower side of the periphery of the discharging cylinder, and the length direction of the discharging port is parallel to the axial direction of the discharging cylinder; A conveying mechanism arranged in the discharging cylinder; The profiling mechanism is arranged on the mounting plate and is used to make the inner wall of one side of the discharge port away from the discharge mechanism flush with the inner wall of the mold frame when the discharge mechanism rotates.

[0010] Further, the conveying mechanism includes a spiral auger coaxially and rotatably connected inside the discharge cylinder, and the spiral auger is driven to rotate by a reduction motor installed on the outer wall of one axial end of the discharge cylinder.

[0011] Further, the discharge mechanism includes a bearing mounting seat fixedly connected to the bottom of the mounting plate. A transition bin is rotatably connected inside the bearing mounting seat through a bearing, and the lower side of the transition bin is communicated with the inner cavity of the discharge cylinder through a hose.

[0012] Further, an annular rack is coaxially and fixedly sleeved at the lower end of the transition bin. A motor is installed on the top of the mounting plate, and a gear is fixedly sleeved on the motor shaft of the motor. The gear is externally meshed with the annular rack.

[0013] Further, a clamping ring is fixedly connected to the outer wall of the transition bin through a column, and the discharge cylinder is coaxially and slidably engaged with the clamping ring.

[0014] Further, a convex strip is horizontally and fixedly connected to the inner wall of the clamping ring, and a sliding groove for the convex strip to slide and engage is formed on the periphery of the discharge cylinder.

[0015] Further, a guide plate is rotatably connected to the discharge port through a mounting pivot, and a rotating assembly is arranged on the column for driving the guide plate to rotate when the discharge cylinder moves horizontally relative to the clamping ring.

[0016] Further, the rotating assembly includes a swing arm fixedly connected to the end of the pivot. A hinge rod is hinged on the swing arm, and the end of the hinge rod away from the swing arm is hinged to the outer wall of the column.

[0017] Further, the profiling mechanism includes a profiling frame fixedly connected to the frame and hollow in the middle. The contour of the hollow part of the profiling frame is adapted to the contour of the inner cavity of the mold frame. One end of the discharge cylinder is connected to a roller support, and a roller is rotatably connected to the roller support. The roller is in rolling contact with the inner side wall of the hollow part of the profiling frame.

[0018] Further, ear blocks are fixedly connected to the outer wall of the clamping ring and the outer wall of the discharge cylinder respectively, and a spring is fixedly connected between the two corresponding ear blocks. The spring gives the discharge cylinder the potential energy to move away from the clamping ring.

[0019] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, through a carefully designed conveying mechanism, the shavings material freely falling from the discharge barrel can be efficiently and accurately spread evenly and orderly into the internal cavity of the mold frame. This process not only ensures the uniform distribution of the shavings in the mold frame, but also lays a solid foundation for the subsequent molding process. In the complex operation of rotating the discharge barrel to spread the material, the flow direction of the shavings at the discharge port is accurately controlled, which effectively prevents the shavings from scattering due to the centrifugal force generated by the rotation, ensuring that each piece of shavings can accurately fall into the designated area of ​​the mold frame and never cross the boundary to the outside. Therefore, the spreading process is guaranteed to be highly flexible and uniform, and the shavings can be spread evenly and delicately in both the corners and the center area of ​​the mold frame, providing a strong guarantee for the molding quality of subsequent products. 2. In the present invention, by using a reduction motor as a driving source, the speed of the reduction motor is precisely controlled to drive the spiral auger to perform a stable and continuous rotational motion. This mechanical transmission method can effectively guide the shavings to form a uniform flow state in the conveying channel; the unique structural design of the spiral auger can not only push the shavings to be conveyed in a predetermined direction during rotation, but also use the gap between the spiral blades to perform fine diversion and combing of the shavings, ensuring that each piece of shavings can move along a preset trajectory; with the continuous rotation of the spiral auger, the shavings are gradually pushed to the discharge port position, and fall freely from the discharge port at a uniform rate under the action of gravity, thereby completely avoiding the phenomenon of shavings being accumulated in a local area of ​​the inner cavity of the mold frame due to uneven conveying, and ensuring the smoothness and efficiency of the production process; 3. In the present invention, when the discharge barrel gradually moves toward the corner position of the profiling frame during the operation of the equipment, its motion trajectory interacts with the special geometric shape of the profiling plate; in this process, the displacement of the discharge barrel drives the hinge rod connected to it, and the hinge rod deforms due to the force and generates tension, thereby pulling the swing arm hinged to it; under the action of the tension, the swing arm swings regularly around its fixed axis, and this swinging action has clear directionality and amplitude control; As the swing arm swings, the guide plate connected to it also produces a linkage effect. Driven by the swing arm, the guide plate tilts and swings toward the outside of the contour plate, forming a specific angle and posture. The adjustment of this angle and posture allows some of the shavings originally in the discharge port to slide smoothly along the carefully designed smooth surface of the guide plate; these slid shavings, under the dual effects of gravity and the guidance of the guide plate, fall accurately into the corner of the mold frame cavity. This process effectively solves the problem of less shavings at the corner of the mold frame cavity due to structural design or material flow characteristics, ensuring that the shavings in various parts of the mold frame cavity are more evenly distributed, thereby improving the overall processing quality and production efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0023] See also Figures 1-8 The present invention provides a technical solution: a uniformly paved particle board paving device, comprising a conveyor 1, which can be a belt-type conveying device, and is used to convey a mold frame 5, the mouth of the inner cavity of the mold frame 5 faces upward, a frame 2 is installed on the top of the conveyor 1, a mounting plate 3 is horizontally fixed on the upper side of the frame 2, a hopper 4 is installed on the top of the mounting plate 3, and a through groove that penetrates the lower side of the hopper 4 is opened on the surface of the mounting plate 3; A bearing mounting seat is fixedly connected to the bottom of the mounting plate 3. A transition bin 13 is rotatably connected inside the bearing mounting seat through a bearing. A clamping ring 9 is fixedly connected to the outer wall of the transition bin 13 through a column 16. The clamping ring 9 is in the structure form of an open ring. In addition, a discharge tube 7 is coaxially and slidably engaged inside the clamping ring 9. The discharge tube 7 can freely slide along the axial direction of the discharge tube 7 inside the clamping ring 9. The outlet on the lower side of the transition bin 13 is communicated with the inner cavity of the discharge tube 7 through a hose 21. In addition, a discharge port 10 is integrally and fixedly connected to the outer wall on the lower side of the periphery of the discharge tube 7. The length direction of the discharge port 10 is parallel to the axial direction of the discharge tube 7. In this way, under the action of its own weight, the wood shavings in the hopper 4 will enter the hose 21 from the transition bin 13 and enter the discharge tube 7 from the hose 21. In addition, a spiral auger 22 is rotatably connected coaxially inside the discharge tube 7 through a mounting bearing. A reduction motor 15 is mounted on the outer wall at one end in the axial direction of the discharge tube 7. The motor shaft of the reduction motor 15 is connected to the end of the spiral auger 22. Furthermore, it can drive the spiral auger 22 to rotate by rotating the motor shaft of the reduction motor 15, and then can produce a stirring and conveying effect on the wood shavings falling into the discharge tube 7, and make the wood shavings fall evenly along the mouth of the discharge port 10. In addition, a convex strip is horizontally and fixedly connected to the inner wall of the clamping ring 9. A sliding groove for the convex strip to slide and engage is formed on the periphery of the discharge tube 7. The convex strip slides in the sliding groove, so that the discharge tube 7 will not generate circumferential deflection inside the clamping ring 9.

[0024] In the above structure, through the carefully designed conveying mechanism, the wood shaving materials freely falling from the discharge tube can be efficiently and accurately paved into the inner cavity of the mold frame in a uniform and orderly manner. This process not only ensures the uniformity of the distribution of wood shavings in the mold frame, but also lays a solid foundation for the subsequent forming process. In the complex operation of rotating and paving by the discharge tube, the flow direction of the wood shavings at the discharge port is accurately controlled, effectively preventing the scattering of wood shavings caused by the centrifugal force generated by rotation, ensuring that each piece of wood shaving can accurately fall into the designated area of the mold frame and never cross the boundary to the outside; Therefore, it ensures the paving process with high flexibility and uniformity. Whether it is the corner or the central area of the mold frame, the wood shavings can be evenly and carefully sprinkled, providing a strong guarantee for the forming quality of the subsequent products. By using a reduction motor as the driving source and precisely regulating its rotation speed to drive the spiral auger to perform a stable and continuous rotational motion, this mechanical transmission method can effectively guide the wood shavings to form a uniform flow state in the conveying channel; The unique structural design of the spiral auger enables it to not only push the wood shavings to be conveyed along the established direction during rotation, but also use the gaps between the spiral blades to conduct a detailed diversion and combing of the wood shavings, ensuring that each piece of wood shaving can move along the preset trajectory; With the continuous rotation of the spiral auger, the wood shavings are gradually pushed to the position of the discharge port and freely fall from the discharge port at a uniform rate under the action of gravity, thus completely avoiding the phenomenon of the accumulation of wood shavings in the local area of the inner cavity of the mold frame caused by uneven conveying, and ensuring the smoothness and high efficiency of the production process.

[0025] An annular rack 12 is coaxially and fixedly sleeved on the lower end of the transition bin 13, and a motor 14 is installed on the top of the mounting plate 3. The motor shaft of the motor 14 is fixedly sleeved with a gear 8, and the gear 8 is externally meshed with the annular rack 12. The motor 14 is started to drive the gear 8 to rotate. When the gear 8 rotates, it will mesh with the annular rack 12, thereby driving the transition bin 13 to rotate. When the transition bin 13 rotates, the clamping ring 9 and the discharge barrel 7 are driven to rotate around the axis of the transition bin 13 through the column 16; The discharge port 10 is rotatably connected with a guide plate 19 by installing a pivot, and a swing arm 20 is fixedly connected to the end of the pivot. The upper end of the swing arm 20 in the length direction extends upward and has an angle with the axial direction of the discharge barrel 7. A hinge rod 18 is hinged on the swing arm 20, and one end of the hinge rod 18 away from the swing arm 20 is hinged to the outer wall of the column 16. When the discharge barrel 7 moves in the direction away from the clamping ring 9, since the upper end of the hinge rod 18 does not change its position, when the discharge barrel 7 moves, it will drive the swing arm 20 to move, so that the lower end of the hinge rod 18 pulls the swing arm 20 to move, thereby enabling the swing arm 20 to drive the pivot. When the pivot rotates, it can drive the guide plate 19 to rotate, thereby playing a guiding effect on the falling of the shavings; when the discharge cylinder gradually moves toward the corner position of the profiling plate during the operation of the equipment, its motion trajectory interacts with the special geometric shape of the profiling plate; in this process, the displacement of the discharge cylinder drives the hinge rod connected to it, and the hinge rod is deformed due to the force and generates tension, thereby pulling the swing arm hinged to it; under the action of the tension, the swing arm swings regularly around its fixed axis, and this swinging action has clear directionality and amplitude control; As the swing arm swings, the guide plate connected to it also produces a linkage effect. Driven by the swing arm, the guide plate tilts and swings toward the outside of the contour plate, forming a specific angle and posture. The adjustment of this angle and posture allows some of the shavings originally in the discharge port to slide smoothly along the carefully designed smooth surface of the guide plate; these slid shavings, under the dual effects of gravity and the guidance of the guide plate, fall accurately into the corner of the mold frame cavity. This process effectively solves the problem of less shavings at the corner of the mold frame cavity due to structural design or material flow characteristics, ensuring that the shavings in various parts of the mold frame cavity are more evenly distributed, thereby improving the overall processing quality and production efficiency.

[0026] On the frame 2, a profiling frame 6 with a hollow middle is fixedly connected by a suspension rod. The contour of the hollow part of the profiling frame 6 is adapted to the contour of the inner cavity of the mold frame 5. One end of the discharge cylinder 7 is connected to a roller support 11. A roller 23 is rotatably connected to the roller support 11. The roller 23 is in rolling contact with the inner side wall of the hollow part in the middle of the profiling frame 6. Ear blocks are fixedly connected to the outer wall of the clamping ring 9 and the outer wall of the discharge cylinder 7 respectively, and a spring 17 is fixedly connected between two corresponding ear blocks. The spring 17 imparts potential energy to the discharge cylinder 7 to move away from the clamping ring 9.

[0027] The working principle of the present invention: The mold frame 5 is placed flat on the belt body of the conveyor 1 at equal intervals by an external manipulator or other tool equipment. The conveyor 1 is started and the mold frame 5 is alternately conveyed under the hopper 4. When it is conveyed under the hopper 4, the conveyor 1 stops briefly, and the external control cabinet controls the reduction motor 15 to work. When the reduction motor 15 works, it can drive the spiral auger 22 to rotate. When the spiral auger 22 rotates, it can evenly stir the wood shavings falling into the discharge cylinder 7 and make the wood shavings spread from the discharge port 10 into the inner cavity of the mold frame 5; When the reduction motor 15 is started, the synchronous motor 14 is started at the same time. The motor shaft of the motor 14 rotates, and then drives the gear 8 to rotate. When the gear 8 rotates, it will engage with the annular rack 12, and then can drive the transition bin 13 to rotate. When the transition bin 13 rotates, it drives the clamping ring 9 and the discharge cylinder 7 to rotate around the axis of the transition bin 13 through the column 16. During the rotation of the discharge cylinder 7, the spring 17 generates an elastic abutting force on the ear block on the outer wall of the discharge cylinder 7, so that the roller 23 can maintain a rolling contact state with the inner side wall of the hollow part of the profiling frame 6. In addition, in order to enable the roller 23 to smoothly roll from one inner wall of the profiling frame 6 to the adjacent inner wall, an arc-shaped chamfer can be set at the corner of the inner wall of the profiling frame 6, so that the roller 23 can smoothly roll to the other inner wall through the chamfer; As the roller 23 approaches the corner of the inner side wall of the hollow part of the profiling frame 6, since a chamfer is provided at the corner of the inner side wall of the profiling frame 6 while no chamfer is provided at the corner of the inner cavity of the mold frame 5, the wood shavings falling from the discharge port 10 may not be able to be sprinkled on the corner of the inner cavity of the mold frame 5 at this time, or the wood shavings at the corner of the inner cavity of the mold frame 5 are less than those at other parts. Therefore, in this embodiment, when the discharge cylinder 7 moves towards the corner of the profiling frame 6, since the upper end position of the hinge rod 18 remains unchanged, when the discharge cylinder 7 moves, it will drive the swing arm 20 to move, so that the lower end of the hinge rod 18 pulls the swing arm 20 to move, and then the swing arm 20 can drive the pivot to rotate. When the pivot rotates, it can drive the deflector 19 to rotate towards the outer side of the profiling frame 6, and the wood shavings will slide down along the surface of the deflector 19 to the corner of the inner cavity of the mold frame 5, thus playing a role in guiding the falling of the wood shavings.
