Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a wood preservation treatment device. Background Technology

[0002] Wood gradually rots over time, affecting the lifespan and safety of wooden buildings. To extend the lifespan of building timber, preservative-treated wood has been developed. Preservative-treated wood is made by artificially adding chemical preservatives to ordinary wood, giving it properties such as corrosion resistance, moisture resistance, fungal resistance, insect resistance, mildew resistance, and water resistance. Currently, some wood preservation treatments generally involve manually applying preservative paint to the surface of the wood to achieve the purpose of preservation. However, in actual operation, the preservative paint is not applied evenly, resulting in low treatment efficiency.

[0003] For example, a wood preservation treatment device disclosed in Chinese patent literature (publication number: CN221951486U) improves the efficiency of preservation treatment by setting paint delivery pipes and nozzles on both sides of the wood body and by setting up a pump body and delivery pipes to facilitate the pumping of preservative paint from the paint storage tank to the paint delivery pipes and nozzles, thus facilitating spraying on both sides of the wood. Furthermore, by setting up a clamping mechanism, the clamping plate can be moved by rotating a lever to clamp and fix the wood body, improving stability. The moving mechanism allows for the even movement of the paint delivery pipes and nozzles, resulting in more uniform spraying and improved preservation effect. This solves the problem that existing wood preservation treatments generally rely on manual application of preservative paint to the wood surface, which often results in uneven paint application, low processing efficiency, and difficulty in simultaneously treating both sides of the wood, leading to poor treatment effect and slow processing speed.

[0004] However, after the spray nozzle applies the anti-corrosion paint to both sides of the board, the excess paint will slide down the vertical edge of the board onto the processing table due to the imbalance of surface tension, resulting in waste and pollution. Furthermore, the anti-corrosion paint needs to wait for natural drying after spraying, which takes a long time and seriously affects the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the waste that easily occurs when spraying anti-corrosion paint onto boards, and the long natural drying time that affects processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wood preservation treatment device includes a processing table with a paint tank at the upper end. Placement plates are fixedly connected to the inner walls of both sides of the paint tank. Servo electric cylinders are fixedly installed on both sides of the processing table in a symmetrical arrangement. One end of the piston rod of the servo electric cylinder passes through the interior of the paint tank and is fixedly connected to a clamping plate.

[0008] A moving mechanism is provided above the processing table. The moving mechanism includes guide rails. The lower ends of the two guide rails are symmetrically distributed and fixedly connected to the upper end of the processing table. A moving sleeve is slidably sleeved on the outside of the guide rails. A mounting plate is fixedly connected to the upper end of the moving sleeve. A servo motor is fixedly installed on the front of the processing table.

[0009] A spray drying mechanism is provided above the mounting plate.

[0010] Preferably, the output shaft of the servo motor is fixedly mounted with a lead screw via a coupling, and one end of the lead screw is rotatably connected to a fixing block via a bearing. The back of the fixing block is fixedly connected to the front of the processing table.

[0011] Preferably, the lead screw is externally threaded with a threaded block, one end of which is fixedly connected to the front of one of the movable sleeves.

[0012] Preferably, the spraying and drying mechanism includes a linkage frame, the two ends of which are fixedly connected to the upper ends of the two mounting plates respectively, and the opposite ends of the two mounting plates are respectively fixedly connected to symmetrically distributed spraying square tubes and drying square tubes.

[0013] Preferably, the two spraying square tubes are equipped with spray nozzles arranged in a linear array on their opposite surfaces, and the two drying square tubes are provided with air outlets arranged in a linear array on their opposite surfaces. A booster pump is fixedly installed at the upper end of the mounting plate.

[0014] Preferably, one end of the booster pump is fixedly connected to an extraction pipe, one end of which extends into the interior of the paint tank, and the other end of the booster pump is fixedly connected to a delivery pipe, one end of which is fixedly connected to the front of the spraying square tube. A heating box is fixedly installed on the upper end of the mounting plate.

[0015] Preferably, a blower is fixedly installed on the front of the heating box, a temperature sensor is fixedly installed on the inner top wall of the heating box, heating rods arranged in a linear array are fixedly installed on the inner walls of both sides of the heating box, and a connecting pipe is fixedly connected to the back of the heating box, with one end of the connecting pipe fixedly connected to the front of the drying square tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the servo electric cylinder can stably clamp wood of different sizes through the synergistic effect of clamping and fixing, moving spraying, and drying and recycling, ensuring that the wood does not shift during spraying. The moving mechanism drives the spraying and drying components to move at a uniform speed, achieving uniform spraying and drying on both sides of the wood. The nozzle of the spraying square tube ensures that the anti-corrosion paint is evenly covered. The heating box, together with the drying square tube, can greatly accelerate the drying speed of the paint. Excess paint is guided back to the paint tank through the inclined surface of the placement plate, reducing waste and pollution, and also reducing costs. This invention solves the problems of paint waste, pollution, and slow drying in traditional devices. Attached Figure Description

[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a wood preservation treatment device, including a processing table 1. The processing table 1 serves as the basic carrier of the entire device, providing a stable installation platform for each component. The paint tank 2 opened at its upper end is used to store the preservative paint for easy extraction and use later.

[0029] The placement plates 3 fixed to the inner walls on both sides of the paint tank 2 not only support the wood to be treated, but also have sloping designs on both sides at the top, which allow excess anti-corrosion paint to flow along the sloping surfaces during the spraying process and be eventually recycled back into the paint tank 2. This effectively reduces paint waste, lowers production costs, and prevents excess paint from accumulating and polluting the processing table 1 and the surrounding environment. It also prevents paint from corroding the metal parts of the processing table 1, ensuring the long-term stable operation of the device.

[0030] The servo electric cylinders 4, which are symmetrically distributed and fixedly installed on both sides of the processing table 1, have piston rods that penetrate into the paint tank 2 and are fixedly connected to the clamping plate 5. The servo electric cylinders 4 can precisely control the extension and retraction of the piston rods according to the different sizes of the wood, thereby driving the clamping plate 5 to move towards both ends of the wood. This achieves stable clamping of wood of different sizes, ensuring that the wood does not shift or shake during subsequent spraying and drying processes. This provides a stable and reliable foundation for the uniform spraying of anti-corrosion paint and guarantees the quality of the anti-corrosion treatment.

[0031] The moving mechanism above the processing table 1 consists of a guide rail 6, a moving sleeve 61, a mounting plate 62, a servo motor 63, a lead screw 64, a fixing block 65, and a threaded block 66.

[0032] The lower ends of the two guide rails 6 are symmetrically fixed to the upper end of the processing table 1, providing guiding support for the sliding of the movable sleeve 61. The output shaft of the servo motor 63 drives the lead screw 64 to rotate through the coupling. The threaded block 66 connected to the external thread of the lead screw 64 moves with the rotation of the lead screw 64. Since one end of the threaded block 66 is fixed to the front of one of the movable sleeves 61, the movable sleeve 61 is driven to slide smoothly along the guide rail 6. The mounting plate 62 at the upper end of the movable sleeve 61 also moves accordingly. The two mounting plates 62 can be driven to move synchronously through the linkage frame 7.

[0033] This moving method ensures that the spraying and drying components move at a uniform speed and stably, allowing both sides of the wood to be evenly sprayed with preservative paint and dried, thus improving the uniformity and efficiency of the preservative treatment.

[0034] The spraying and drying mechanism above the mounting plate 62 connects the two mounting plates 62 through the linkage frame 7, ensuring the synchronicity of the movement of the spraying square tube 71 and the drying square tube 72.

[0035] The spray nozzles 73, which are linearly arrayed and installed on the opposite surfaces of the two spray tubes 71, can be evenly sprayed onto both sides of the wood by the booster pump 75. This ensures that the anti-corrosion paint drawn from the paint tank 2 through the extraction pipe 76 and transported through the delivery pipe 77, and that the anti-corrosion paint is evenly covered on the wood surface without any missed spraying or accumulation, thus improving the adhesion of the anti-corrosion paint.

[0036] The air outlets 74, which are arranged in a linear array on the opposite surfaces of the two drying square tubes 72, cooperate with the heating box 78, the blower 79, the heating rod 711 and the connecting pipe 712.

[0037] The heating rod 711 inside the heating chamber 78 generates heat when powered on, which can heat the air inside the heating chamber 78 to a suitable temperature. The temperature sensor 710 can monitor the temperature in real time, making it easy to control.

[0038] When the blower 79 is working, it blows flowing air into the heating box 78, mixes with the heated air to form hot air, and the hot air is delivered to the drying square tube 72 through the connecting pipe 712, and then blown onto the surface of the wood that has been painted through the air outlet 74. This can greatly accelerate the drying and curing speed of the anti-corrosion paint. Compared with natural drying, it greatly improves the processing efficiency and allows the wood to enter the next process faster.

[0039] It should be noted that the electrical equipment mentioned above is all programmed and controlled using existing PLC controllers. Since this is a mature technology, it will not be described in detail.

[0040] The working process of this utility model:

[0041] Step 1: Place the wood to be treated with preservative above the placement plates 3 on both sides of the paint tank 2 on the processing table 1. Start the servo electric cylinder 4, and its piston rod extends, driving the clamping plate 5 to move towards both ends of the wood until the clamping plate 5 is tightly attached to both ends of the wood, clamping and fixing the wood. The clamping force can be adjusted according to the size of the wood to ensure that the wood does not shift or shake during the subsequent spraying and drying process, providing a stable foundation for the uniform spraying of the preservative paint. Start the servo motor 63, and its output shaft drives the lead screw 64 to rotate through the coupling. The threaded block 66 connected to the external thread of the lead screw 64 moves with the rotation of the lead screw 64. Since one end of the threaded block 66 is fixed to one of the moving sleeves 61, it drives the moving sleeve 61 to slide along the guide rail 6. The mounting plate 62 at the upper end of the moving sleeve 61 moves accordingly, and the two mounting plates 62 move synchronously through the linkage frame 7.

[0042] Step two: Simultaneously, the booster pump 75 is started. The booster pump 75 extracts the anti-corrosion paint from the paint tank 2 through the extraction pipe 76, and delivers it to the spraying square tube 71 through the delivery pipe 77. Finally, the anti-corrosion paint is evenly sprayed on both sides of the wood through the nozzles 73 arranged in a linear array on the surface of the spraying square tube 71. During the movement, the nozzles 73 sweep across the surface of the wood at a uniform speed to ensure that the anti-corrosion paint is evenly covered on both sides of the wood without any missed spraying or accumulation. At the same time as spraying, the heating rod 711 and the blower 79 in the heating box 78 are started. The heating rod 711 is energized and heats up the air inside the heating box 78 to a suitable temperature. The blower 79 works and blows the flowing air into the heating box 78, which mixes with the heated air to form hot air. The hot air is delivered to the drying square tube 72 through the connecting pipe 712, and then blown onto the wood surface that has been painted through the air outlets 74 arranged in a linear array on the surface of the drying square tube 72, accelerating the drying and curing of the anti-corrosion paint.

[0043] Step 3: During the spraying process, excess anti-corrosion paint will slide off the wood surface onto the placement board 3. Since the upper sides of the placement board 3 are designed with slopes, the sliding paint will be guided along the slopes and eventually recycled into the paint tank 2. This not only reduces paint waste and lowers production costs, but also avoids pollution caused by excess paint accumulating on the processing table 1 and the rusting effect on the metal parts of the processing table 1, thus ensuring the long-term stable operation of the device.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
