Description

Technical Field

[0001] This utility model relates to the field of negative oxygen ion additive application technology for particleboard, specifically a device for quantitatively applying negative oxygen ion additives to particleboard. Background Technology

[0002] Currently, in the production process of particleboard, in order to give it the function of releasing negative oxygen ions, negative oxygen ion additives need to be applied to the surface or interior of the particleboard.

[0003] Current application methods mostly involve manual brushing or simple pipe pouring. Manual brushing is prone to uneven application due to operator differences, resulting in localized over- or under-application of additives, affecting the consistency of negative ion release from the particleboard. Simple pipe pouring lacks an effective mixing mechanism, causing negative ions and additives to separate, and making it impossible to accurately control the application amount, leading to material waste. Furthermore, existing equipment is difficult to adapt to the application requirements of different particleboard sizes, lacks adjustment flexibility, and some parts of the equipment that come into contact with the additives are susceptible to corrosion, not only contaminating the additives but also shortening the equipment's lifespan, making it difficult to meet the demands of large-scale, high-quality particleboard production. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to the following: Figure 1-3 , A device for quantitatively applying negative ion additives to particleboard, comprising: The base plate 1 and the L-shaped plate 2 are fixedly installed on the top of the base plate 1; Two hydraulic rods 3 are fixedly installed on the outside of the L-shaped plate 2; Fixed plate 4 is fixedly installed at the output end of hydraulic rod 3; The mixing tank 7 is fixedly installed at the bottom of the fixing plate 4 by two support rods; The motor is fixedly installed at the bottom of the fixing plate 4, and its output end extends into the interior of the mixing tank 7; The stirring shaft 9 is located inside the stirring tank 7 and is fixedly connected to the output end of the motor. The feed pipe 5 and the air inlet pipe 6 are both connected to the inside of the mixing tank 7. And the spray pipe 8 is connected to the bottom of the mixing tank 7, and the feed pipe 5, the air inlet pipe 6 and the spray pipe 8 are all equipped with solenoid valves. Specifically, the structural foundation is built as follows: the base plate 1 provides overall support for the equipment, the L-shaped plate 2 serves as the mounting carrier for the hydraulic rod 3, and the hydraulic rod 3 can adjust the height of the fixing plate 4 and the mixing tank 7 by telescopic adjustment, laying the foundation for subsequent spraying distance adjustment; Material injection and mixing: Open the solenoid valve of feed pipe 5, and the negative oxygen ion additive enters the mixing tank 7 through feed pipe 5. After closing the solenoid valve of feed pipe 5, start the motor. The motor drives the mixing shaft 9 to rotate in the mixing tank 7 to achieve uniform mixing of the additive and avoid component stratification that affects the spraying effect. Quantitative spraying drive: Place the particleboard on the base plate 1, connect an external air pump through the air inlet pipe 6, open the solenoid valve of the air inlet pipe 6 to pressurize the mixing tank 7, and then open the solenoid valve of the spray pipe 8. Use the pressure inside the tank to quantitatively deliver the mixed negative oxygen ion additive to the surface of the particleboard through the spray pipe 8 to complete the application process; the solenoid valves of each pipe can be independently controlled to ensure the accuracy of material delivery and pressure regulation; In this embodiment: the support rod is connected to the fixed plate 4 and the mixing tank 7 by welding, and the two support rods are symmetrically distributed about the central axis of the motor; Specifically, connection stability is ensured: the support rod is fixed to the fixing plate 4 and the mixing tank 7 by welding. Compared with bolt connection and other methods, welding can greatly improve the connection strength and prevent the mixing tank 7 from loosening or shifting when the mixing shaft 9 rotates at high speed or when the tank is pressurized, thus ensuring the stability of the mixing and spraying process. Optimized force balance: The two support rods are symmetrically distributed about the central axis of the motor, which can evenly transfer the weight of the mixing tank 7 to the fixed plate 4, avoiding the tilting of the fixed plate 4 due to uneven weight distribution, thereby preventing the mixing shaft 9 from rubbing against the inner wall of the mixing tank 7 and the spraying position of the spray pipe 8 from shifting, ensuring the mixing effect and spraying accuracy. In this embodiment: at least two sets of stirring blades are also fixedly sleeved on the outer wall of the stirring shaft 9, and the stirring blades are evenly distributed along the length direction of the stirring shaft 9. Specifically, the mixing efficiency is improved: at least two sets of stirring blades are fixed on the outer wall of the stirring shaft 9. When the stirring shaft 9 rotates, the blades can more fully stir the additives in the mixing tank 7. Compared with relying solely on the rotation of the stirring shaft 9 itself, the blades can expand the stirring range, break the agglomeration of additives, and make the negative oxygen ion components and other additive components mix more evenly. Uniform mixing is ensured: The mixing blades are evenly spaced along the length of the mixing shaft 9, which can cover materials at different heights in the mixing tank 7, avoiding the problem of sufficient mixing in the upper layer and insufficient mixing in the lower layer. This ensures that all additive components in the mixing tank 7 reach a consistent mixing state, thereby ensuring that the additive components sprayed onto the particleboard are uniform and improving the negative oxygen ion release effect of the particleboard. In the embodiment, it also includes: An air pump is detachably connected to the end of the air inlet pipe 6 away from the mixing tank 7 to deliver gas into the mixing tank 7 to achieve pressurization; Specifically, the booster power supply: the air pump and the end of the air inlet pipe 6 away from the mixing tank 7 can be detached. When in use, the air pump is connected to the air inlet pipe 6. After the air pump is started, high-pressure gas enters the mixing tank 7 through the air inlet pipe 6, making the air pressure inside the tank higher than the outside atmospheric pressure, thus forming a pressure difference. Quantitative spraying guarantee: The pressure difference inside the tank is the core driving force for pushing the additive through the spray pipe 8. The air pump can control the pressure inside the mixing tank 7 by adjusting the output air pressure, thereby controlling the speed and flow rate of the additive from the spray pipe 8 to achieve quantitative spraying on demand; The detachable connection design facilitates the maintenance and replacement of the air pump, and also makes it easy to store the equipment when not in use. In the embodiment: an atomizing nozzle is also provided at the end of the spray pipe 8 away from the mixing tank 7. The atomizing nozzle is threadedly connected to the spray pipe 8 so as to atomize the negative oxygen ion additive and spray it onto the particleboard surface. Specifically, the spraying pattern is optimized: the atomizing nozzle is threadedly connected to the spray pipe 8. The pressure inside the mixing tank 7 pushes the additive to the atomizing nozzle, and the nozzle disperses the additive into fine mist particles through its internal structure. Compared with columnar or flow-like additives that flow directly through the spray pipe 8, the mist particles can be more evenly dispersed on the particleboard surface. Uniform coverage is guaranteed: mist spraying avoids the problem of local accumulation or gaps of additives on the particleboard surface, ensuring that each unit area of ​​particleboard is covered with an equal amount of negative oxygen ion additives; the threaded connection design makes it easy to change the nozzle with different atomization effects according to the size and thickness of the particleboard, improving the adaptability of the equipment. In this embodiment: a positioning groove is also provided on the top of the base plate 1. The size of the positioning groove is adapted to the size of the particleboard and is used to position and place the particleboard. Specifically, the positioning reference is provided: the size of the positioning groove is adapted to the size of the particleboard. When placing the particleboard, the edge of the particleboard is aligned with the inner wall of the positioning groove, which can quickly determine the placement position of the particleboard and avoid the relative position shift between the particleboard and the spray pipe 8 due to manual placement deviation. Precision spraying is guaranteed: The positioning groove can limit the movement of the particleboard during the spraying process, prevent the particleboard from shifting due to equipment vibration or airflow, and ensure that the additive sprayed from the spray pipe 8 can accurately cover the target area of ​​the particleboard, avoiding waste caused by the additive being sprayed on the outside of the particleboard, while ensuring that the amount of additive applied to each area of ​​the particleboard is consistent. In the embodiment: the extension stroke range of the hydraulic rod 3 is 50-300mm, so that by adjusting the extension of the hydraulic rod 3, the fixed plate 4 and the mixing tank 7 can be moved up and down, thereby changing the distance between the spray pipe 8 and the particleboard. Specifically, the distance adjustment principle is as follows: the extension and retraction range of the hydraulic rod 3 is 50-300mm. When it is necessary to spray particleboard of different thicknesses or sizes, the extension or retraction of the hydraulic rod 3 can be controlled to drive the fixed plate 4 and the mixing tank 7 to move up and down synchronously, thereby changing the distance between the spray pipe 8 and the particleboard surface. Adaptability and coating effect guarantee: For thicker particleboard, the hydraulic rod 3 can be shortened to bring the spray pipe 8 closer to the particleboard, avoiding excessive diffusion of the mist additive during the fall; for thinner or larger particleboard, the hydraulic rod 3 can be lengthened to increase the spraying range and ensure that a larger area is covered in one spray; the reasonable stroke range can take into account the needs of various particleboard specifications, improve the versatility of the equipment, and at the same time ensure the uniformity of spraying in different scenarios; In the embodiment: the mixing tank 7 is made of stainless steel, and the inner wall of the mixing tank 7 is provided with an anti-corrosion coating, which is a polytetrafluoroethylene coating. Specifically, durability is guaranteed: the mixing tank 7 is made of stainless steel, which has high strength and corrosion resistance. It can withstand the impact of the rotating mixing shaft 9 and the internal pressure brought by the air pump, while avoiding long-term contact with additives that could cause the tank to rust and extending the service life of the equipment. Additive purity guaranteed: The inner wall of the mixing tank 7 is coated with a polytetrafluoroethylene (PTFE) anti-corrosion coating. PTFE has excellent chemical stability and will not react with the negative oxygen ion additives, thus preventing the tank material from leaching out and contaminating the additives. At the same time, the smooth surface of the coating can reduce the residue of additives on the tank wall, ensuring that the additive components are pure and the dosage is accurate each time they are sprayed, and preventing residual additives from deteriorating and affecting the subsequent use effect. Working principle: First, place the particleboard on the base plate 1, open the solenoid valve of the feed pipe 5 to allow the negative oxygen ion additive to enter the mixing tank 7, then close the solenoid valve and start the motor. The motor drives the mixing shaft 9 to rotate, uniformly mixing the additive. After mixing, connect the air inlet pipe 6 to an external air pump, open the solenoid valve of the air inlet pipe 6 to pressurize the mixing tank 7, and then open the solenoid valve of the spray pipe 8. The pressure inside the tank is used to spray the mixed additive onto the particleboard surface through the spray pipe 8 in a measured amount. During the process, the height of the fixing plate 4 and the mixing tank 7 can be adjusted by extending and retracting the hydraulic rod 3 to adapt to different spraying needs. Each pipe solenoid valve is independently controlled to ensure operational precision.
