Description

Technical Field

[0001] The present application relates to the technical field of plate processing, and in particular to a plate drying mechanism. Background Art

[0002] Wood, with its advantages of light weight, high strength-to-weight ratio, good elasticity, impact resistance, and rich, beautiful textures and tones, is widely used in a variety of furniture, ships, stationery, and other products. Wood processing plays a vital role in the national economy due to its low energy consumption, low pollution, and renewable nature. The board processing process includes multiple steps, such as cutting, sanding, painting, and final assembly.

[0003] When logs are being roughly processed, they need to be cut into pieces of wood. Since the logs usually contain water and moisture when they are not completely air-dried, each piece of wood needs to be dried after cutting. The patent document with the publication number CN115540556A currently discloses a board drying device, which sends the board into a drying box through a conveyor device, and then sprays the board with heated gas through multiple groups of nozzles arranged in a V shape in the drying area to dry the board. At the same time, the exhaust device extracts the water vapor in the drying area to ensure the moisture in the drying area and improve the drying effect; then the board is dissipated through the cooling area to avoid local damage. Finally, the board is dried.

[0004] However, for some wood, when drying, the difference in water evaporation rates between the surface and core of the board leads to uneven shrinkage, which ultimately generates internal stress. If these stresses are not effectively released, it will easily cause the board to crack, warp or deform, seriously affecting the appearance and functionality of the product. Summary of the Invention

[0005] In order to improve the drying effect of the board and reduce the internal stress of the board, the present application provides a board drying mechanism.

[0006] This application provides a plate drying mechanism, which adopts the following technical solutions: A plate drying mechanism includes a drying box, which is divided into a drying area, a sealing area, and a cooling area in sequence from the feed port to the discharge port. A conveying device for moving the plate is provided in the drying box. The characteristics are: a drying mechanism for blowing air to dry the plate is provided in the drying area, and a pressure reducing mechanism for reducing the stress of the plate is also provided in the drying area. The pressure reducing mechanism includes: a first sliding plate, the first sliding plate being slidably arranged on the drying box in a direction perpendicular to the moving direction of the plate and being located above the plate; A sliding drive member, the sliding drive member is provided on the drying box and is used to drive the first sliding plate to slide; An extrusion assembly is provided on the first sliding plate and performs rolling extrusion on the top of the plate as the first sliding plate slides; A heating component is provided on the first sliding plate and is used to heat the contact surface between the extrusion component and the plate.

[0007] By adopting the above technical solution, the conveying device drives the plate to move in the drying box, the drying area blows air to dry the plate through the drying mechanism, the sealing area isolates the cooling area and the drying area, and the cooling area cools the dried plate; the first sliding plate is driven to slide by the sliding drive member, the extrusion assembly slides with the first sliding plate and rolls and extrude the top of the plate, the heating assembly increases the temperature of the contact surface between the plate and the extrusion assembly, and ultimately improves the drying effect of the plate and reduces the internal stress of the plate.

[0008] Furthermore, the extrusion assembly includes: A mounting seat, the mounting seat being slidably disposed on the first sliding plate in a direction approaching or moving away from the plate; A lifting drive member, the lifting drive member is arranged on the first sliding plate and is used to drive the mounting seat to slide, and the lifting drive member is used to adjust the distance between the mounting seat and the plate; A squeezing roller, rotatably mounted on a mounting base and used for rolling and squeezing the top of the plate; A silicone layer is coated on the squeezing roller and enables the squeezing roller to flexibly abut against the plate.

[0009] By adopting the above technical solution, the lifting drive member drives the mounting seat to slide, thereby adjusting the extrusion force of the extrusion roller on the top of the plate. At the same time, the silicone layer makes the extrusion roller and the plate flexibly abut, reducing the probability of damage to the plate. When the first sliding plate slides, it drives the mounting seat to move, thereby causing the extrusion roller to roll and squeeze the plate. The rolling extrusion of the plate by the extrusion roller can squeeze and release the stress in the plate, thereby reducing the internal stress of the plate.

[0010] Furthermore, the mounting base is provided with a circular air inlet cavity, and the heating assembly includes: A heating plate, the heating plate being arranged in an extrusion roller, an annular cavity being provided inside the extrusion roller, and a guide fluid being provided in the annular cavity for guiding the heat of the heating plate to the outside of the extrusion roller; An air inlet pipe is provided on the first sliding plate and communicates with the air inlet cavity. The air inlet pipe is retractable in length and is used to discharge the heated gas in the drying mechanism into the air inlet cavity. The air outlet hood is arranged on the mounting seat and is located at the front end of the extrusion roller in the rolling direction. The air outlet hood is connected to the inside of the air inlet cavity and is used to discharge the gas in the air inlet cavity into the contact surface between the silicone layer and the plate. The air outlet hood is an arc-shaped structure close to the plate surface and allows the gas ejected from the air outlet hood to flow along the side wall of the silicone layer.

[0011] By adopting the above technical solution, the heating plate generates heat and evenly guides it to the squeezing roller through the guide liquid, thereby heating the contact surface between the squeezing roller and the plate. At the same time, the air inlet pipe discharges the heated gas in the drying mechanism into the air inlet chamber, and then blows the hot air to the contact surface between the plate and the squeezing roller in advance through the air outlet hood, and then is squeezed by the squeezing roller, thereby accelerating the drying efficiency of the plate.

[0012] Furthermore, an air suction hood is provided on the mounting seat, and the air suction hood is located at the rear end of the rolling forward direction of the extrusion roller and is used to absorb water vapor evaporated from the surface of the extruded plate. The mounting seat is provided with an inner tube connected to the interior of the air suction hood, and the inner tube coaxially passes through the air inlet cavity and extends into the air suction hood. The inner tube discharges the gas absorbed in the air suction hood into the air outlet hood. The mounting seat is provided with a power component for generating suction for the air suction hood.

[0013] By adopting the above technical solution, after the extrusion roller heats and squeezes the plate, the water vapor in the plate quickly appears on the surface of the plate under the action of pressure, and power is generated by the power component. Then, the suction hood quickly absorbs the evaporated water vapor and discharges it into the air outlet hood through the inner pipe, thereby ultimately improving the drying effect of the plate.

[0014] Furthermore, the power assembly includes: a rotating ring rotatably disposed on the inner tube; Outer rotating blades, multiple groups of the outer rotating blades are circumferentially spaced apart on the outer side of the rotating ring, and the multiple groups of the outer rotating blades are located between the outer side wall of the inner tube and the inner side wall of the air inlet chamber, and the gas in the air inlet chamber blows the multiple groups of the outer rotating blades and drives the rotating ring to rotate; Inner rotating blades, multiple groups of inner rotating blades are circumferentially spaced on the inner side of the rotating ring, multiple groups of inner rotating blades are located in the inner tube, the inclination direction of the inner rotating blades is opposite to that of the outer rotating blades, and when the rotating ring rotates, it drives the multiple groups of inner rotating blades to rotate and suck the gas in the suction hood.

[0015] By adopting the above technical solution, when the gas discharged from the air inlet pipe flows in the air inlet cavity, the gas blows multiple groups of outer rotating blades, thereby causing the multiple groups of outer rotating blades to drive the rotating ring to rotate, and the inner rotating blades rotate with the rotating ring, thereby generating suction in the inner tube, thereby facilitating the inner tube to extract the gas in the suction hood.

[0016] Furthermore, the air outlet hood is provided with a collection component for collecting condensed water generated inside the air outlet hood, and the collection component includes: A baffle, the baffle being tilted and arranged in the air outlet cover, and having a plurality of through holes spaced apart to facilitate the passage of gas, the baffle blocking some water molecules and directing the water to one side by being tilted; A collection box is provided on the air outlet cover and is used to collect water guided by the baffle.

[0017] By adopting the above technical solution, the baffle blocks the gas in the air outlet hood, so that part of the water vapor forms condensed water due to impact on the baffle, and the gas is discharged through the through hole. The condensed water on the baffle is guided to the bottom side by the inclined setting of the baffle. The conical hole facilitates the diversion of the condensed water on the inner wall of the through hole to the side of the baffle away from the plate, and finally enters the collection box for temporary storage, thereby reducing the water vapor content in the exhaust gas from the air outlet hood.

[0018] Furthermore, an extension pipe connected to the inner pipe is provided in the air outlet hood, and the extension pipe is coaxially arranged with the air outlet hood. Spiral guide grooves are provided on the inner and outer walls of the extension pipe. The spiral guide grooves enhance the heat exchange efficiency between the air outlet hood and the extension pipe and guide the airflow to rotate. The condensed water on the inner and outer walls of the extension pipe flows to the bottom along the spiral guide grooves. An annular water collecting trough is provided on the bottom of the extension pipe, and the annular water collecting trough is connected with the collection box. The annular water collecting trough collects the condensed water on the inner and outer walls of the extension pipe and discharges it into the collection box.

[0019] By adopting the above technical solution, due to the difference in gas temperature and humidity in the extension pipe and the air outlet hood, the spiral guide groove guides the gas, which makes it easier for condensed water to flow into the annular water collection tank under the guidance of the spiral guide grooves on the inner and outer walls of the extension pipe, and finally enter the collection box for temporary storage, thereby reducing the moisture content in the exhaust gas from the machine suction hood.

[0020] Furthermore, the collection box includes: A box body, which is arranged on the air outlet cover and is hollow inside, and a drain port is provided at the bottom of the box body; A sealing cover is slidably disposed in the box body and seals the liquid discharge port; A return spring is provided in the box body, and the return spring pushes the sealing cover to press against the box body and seal the liquid discharge port.

[0021] By adopting the above technical solution, when there is no external force, the return spring pushes the sealing cover tightly against the drain port and seals the drain port, so that the box body can store condensed water. When there is an external force, the sealing cover is pushed to slide and the return spring is squeezed, so that the drain port is opened, which facilitates the discharge of condensed water in the box body.

[0022] Furthermore, the drying box is provided with a drainage assembly for automatically draining the condensed water in the collection box, and the drainage assembly includes: A push rod is slidably arranged on the drying box and is used to push the sealing cover moved to a specified position and open the drain port; A push driving member, which is provided on the drying box and is used to drive the push rod to slide; A controller is provided on the drying box and is used to control the start and stop of the push drive member, and the controller is used to control the opening time of the drain port.

[0023] By adopting the above technical solution, when the first sliding plate moves to the specified position and the mounting seat rises to a safe position, the controller starts the push drive and drives the push rod to slide, so that the sealing cover slides and the drain port is opened for a certain period of time, so as to facilitate the timely discharge of condensed water in the box body.

[0024] Furthermore, a support assembly cooperating with the pressure reducing mechanism is provided in the drying box, and the support assembly includes: A second sliding plate is slidingly arranged on the drying box and located below the plate, wherein the sliding direction of the second sliding plate is parallel to the sliding direction of the first sliding plate, and the sliding drive member drives the first sliding plate and the second sliding plate to slide synchronously; A fixing seat, the fixing seat is arranged on the second sliding plate, and the interior of the fixing seat is hollow; The support roller is rotatably arranged on a fixed seat and is used for rolling support of the bottom of the plate. The support roller and the squeezing roller are symmetrically arranged on opposite sides of the plate. A heating plate is also arranged inside the support roller.

[0025] By adopting the above technical solution, the sliding drive member drives the first sliding plate and the second sliding plate to slide synchronously, thereby driving the fixed seat to slide, the support roller provides rolling support to the bottom of the plate, the heating plate increases the temperature of the support roller, and the support roller supports and fixes the side of the plate away from the extrusion roller, thereby reducing the probability of the plate being bent and deformed under the extrusion force of the extrusion roller.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The first sliding plate is driven to slide by the sliding drive member, and the lifting drive member adjusts the extrusion force of the extrusion roller on the plate. Then, the extrusion roller is driven by the first sliding plate to roll and extrude the plate, thereby reducing the stress of the plate. The support roller supports the side of the plate away from the extrusion roller, thereby reducing the probability of the plate bending and deformation under the action of the extrusion roller. At the same time, the temperature of the extrusion roller is increased by the heating plate, and the air outlet hood blows air to heat the contact surface between the plate and the pressure roller in advance, thereby improving the drying effect of the plate and reducing the internal stress of the plate.

[0027] 2. By setting up a suction hood on the mounting base, the water vapor generated by extrusion can be quickly sucked out, and by inserting the extension tube into the air outlet hood, part of the water vapor in the suction hood and the extension tube is converted into condensed water and temporarily stored in the collection box, thereby improving the drying effect of the board.

[0028] 3. By stopping the mounting base at the specified position, the push driving member drives the push rod to slide, thereby pushing the sealing cover to slide and opening the drain port to discharge the condensed water in the collection box, thereby realizing the automatic discharge of the condensed water in the collection box.

The second sliding plate 91 is slidably installed on the drying box 1, and the second sliding plate 91 is located under the plate. The sliding direction of the second sliding plate 91 is parallel to the sliding direction of the first sliding plate 21. The sliding drive 22 drives the first sliding plate 21 and the second sliding plate 91 to slide synchronously. Specifically, the sliding drive 22 includes a first screw rod 221, a second screw rod 222, a driving rod 223, a bevel gear set 224 and a driving motor 225. The first screw rod 221 is rotatably installed on the drying box 1 and is located above the plate. The first sliding plate 21 is threadedly connected to the first screw rod 221. When the first screw rod 221 rotates, it drives the first sliding plate 21 to slide; the second screw rod 222 is rotatably installed on the drying box 1 and is located under the plate. The second screw rod 222 and the first screw rod 221 are parallel to each other, and the second screw rod 222 is threadedly connected to the second sliding plate 91. When the second screw rod 222 rotates, it drives the second sliding plate 91 to slide; the driving rod 223 is rotatably installed on the drying box 1, and the driving rod 223 is perpendicular to the first screw rod 221 and the second screw rod 222. The bevel gear set 224 includes two sets of bevel gears that mesh with each other. The two ends of the driving rod 223 are respectively connected to the first screw rod 221 and the second screw rod 222 through a set of bevel gear sets 224, so that when the driving rod 223 rotates, it also drives the first screw rod 221 and the second screw rod 222 to rotate synchronously, thereby driving the first sliding and second sliding plates 91 to slide synchronously; the driving motor 225 is fixedly installed on the drying box 1, and the driving motor 225 drives the driving rod 223 to rotate through the gear, which ultimately makes it easy to drive the first sliding plate 21 and the second sliding plate 91 to slide at the same time.

[0048] Reference Figure 4 and Figure 5 The fixed seat 92 is fixedly installed on the surface of the second sliding plate 91. The fixed seat 92 is hollow inside. The support roller 93 is rotatably installed on the fixed seat 92. The support roller 93 is used to provide rolling support for the bottom of the plate. The support roller 93 and the extrusion roller 33 are symmetrically arranged on the opposite sides of the plate. A heating plate 41 is also provided inside the support roller 93. The support roller 93 of this embodiment is hollow inside, and a guide liquid is also provided inside the support roller 93 to heat the support roller 93.

[0049] Reference Figures 1-9In order to ensure the drying effect of the plate, the conveying speed of the conveying device 16 is slow, and the external air is sucked into the storage chamber 171 through the first blower 172, and the heater 173 heats the sucked air, and then the heated air is blown to the surface of the plate through the nozzle 1742 on the drying pipe 1741, thereby accelerating the drying effect of the plate; when the plate enters the designated position in the drying area 13, the driving motor 225 is started to drive the first sliding plate 21 and the second sliding plate 91 to move to the designated position, and then the lifting driving member 32 drives the mounting seat 31 to slide and makes the silicone layer 34 on the squeezing roller 33 press against the plate, and the squeezing force of the squeezing roller 33 on the plate can be adjusted by the lifting driving member 32; the driving motor 225 continues to drive the first sliding plate 21 and the second sliding plate 91 to slide synchronously, squeezing The roller 33 and the support roller 93 roll and extrude the opposite ends of the plate respectively. The squeezing roller 33 and the support roller 93 are heated by the heating plate 41, so as to facilitate the rapid drying of the moisture inside the plate; the air outlet hood 43 blows air to the contact surface between the squeezing roller 33 and the plate in advance to heat it, thereby improving the squeezing and drying effect of the squeezing roller 33 on the plate, and at the same time, the suction hood 5 is used to inhale the surface of the squeezed plate, thereby quickly sucking out the evaporated water vapor, further improving the drying effect of the plate; the condensation effect of water vapor in the gas is improved by the extension tube 52 and the spiral guide groove on the extension tube 52, and the condensed water is blocked by the baffle 71 and the collection box 72 and discharged into the collection box 72 for temporary storage, thereby reducing the water vapor content in the gas blown out by the air outlet hood 43; thereby improving the drying effect of the plate and reducing the internal stress of the plate.

[0050] The working principle of the embodiment of this application is as follows: The first sliding plate 21 is driven to slide by the sliding drive member 22, and the lifting drive member 32 adjusts the squeezing force of the squeezing roller 33 on the plate. Then, the squeezing roller 33 rolls and squeezes the plate under the drive of the first sliding plate 21, so as to reduce the stress of the plate. The support roller 93 supports the side of the plate away from the squeezing roller 33, thereby reducing the probability of the plate bending and deformation under the action of the squeezing roller 33. At the same time, the temperature of the squeezing roller 33 is increased by the heating plate 41, and the air outlet hood 43 blows air to heat the contact surface between the plate and the pressure roller in advance, thereby improving the drying effect of the plate and reducing the internal stress of the plate.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
