Description

Technical Field

[0001] The invention relates to the technical field of wood component surface aging processing, and specifically refers to a wood component surface aging drying device, which mainly performs aging processing on the surface of the wood component by fire baking. Background Art

[0002] The methods of aging the surface of wooden components mainly include using professional aging paint, water grinding, fire drying, or directly using paint to age, and using old processing techniques. Among them, fire drying is to reduce the surface moisture of the wooden components, so that the surface texture of the wooden components is clearer, and then after a slight grinding, the sense of age of the wooden components will be revealed.

[0003] The existing wood component surface aging and drying equipment mainly includes a conveyor belt for transmitting wood components, and a fire-baking burning nozzle arranged on the upper part of the conveyor belt. During the process of the wood component transmission mechanism using the fire-baking burning nozzle, the surface of the wood component is directly dried by the flame generated by the fire-baking burning nozzle. Such wood component surface aging and drying equipment has the following defects in actual use: 1) The concave and convex textures on the surface of the wood component are not clear enough, resulting in insufficient clarity of the surface texture of the wood component after fire-baking and drying; 2) Although the concave and convex textures on the surface of the wood component are not clear enough, they still cause differences in the contact rate of the surface of the wood component when it contacts the flame. In addition, the fire-baking and drying time should not be too long, which can easily lead to insufficient uniformity of the fire-baking and drying, resulting in the problem of insufficient uniformity of the surface aging effect of the wood component.

[0004] Therefore, the research purpose of the present invention is to design a wood component surface aging drying equipment that can effectively and significantly improve the clarity of the concave and convex texture on the surface of the wood component, and can effectively improve the surface fire baking and drying uniformity of the wood component, thereby greatly improving the surface aging effect of the wood component. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a device for drying the surface of a wooden component for aging, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A wood component surface aging drying device, comprising:

[0008] A workbench, on which a corresponding cover is fixedly mounted, a feed inlet is provided on the front side of the cover, and a discharge outlet is provided on the rear side of the cover;

[0009] A material transfer mechanism, used for transferring the wood component from the feed port of the cover to the discharge port leaving the cover;

[0010] The surface polishing mechanism comprises a polishing shaft rotatably arranged on one side of the feed end of the cover, the polishing shaft is transmission-connected to the output shaft end of the corresponding driving motor, and a plurality of corresponding polishing bristles are evenly distributed and fixed on the polishing shaft;

[0011] The surface fire roasting mechanism comprises a fuel feed pipe arranged in a cover at the rear side of the surface polishing mechanism, a plurality of corresponding fire roasting nozzles are installed side by side downward on the inner side of the fuel feed pipe, and the outer side of the fuel feed pipe is connected to an external fuel source through a corresponding fuel valve;

[0012] A material blocking mechanism is arranged between the surface polishing mechanism and the surface roasting mechanism, and is used to block the wood chips formed by the surface polishing mechanism from falling back to the surface of the wood component;

[0013] The smoke exhaust mechanism comprises an air collecting hood arranged on the upper side of the fire roasting nozzle, and the air collecting hood is connected to the feed end of the external exhaust gas treatment system through a corresponding exhaust pipe and an exhaust fan.

[0014] The material baffle mechanism includes a material baffle plate obliquely arranged between the surface polishing mechanism and the surface roasting mechanism, the front end of the material baffle plate is located at the rear side of the polishing shaft and abuts against the polishing bristles located at the rear side of the polishing shaft, and the rear end of the material baffle plate is arranged with a gap between it and the surface of the wooden component.

[0015] The baffle plate is fixedly connected to the cover, and a group of side baffles located at both sides of the wooden component are arranged on the bottom side of the baffle plate.

[0016] A group of lifting cylinders are fixedly connected to the cover on the upper side of the polishing shaft. The piston rod ends of the lifting cylinders are arranged downward and fixedly connected to corresponding mounting seats. The two ends of the polishing shaft are rotatably mounted on the mounting seats respectively, and the driving motor is fixedly mounted on one of the mounting seats.

[0017] A corresponding smoke concentration sensor is fixedly installed on the exhaust pipe. During the roasting process of the wooden component surface, when the concentration value detected by the smoke concentration sensor is lower than the set value P1, the piston rod of the lifting cylinder extends to increase the contact amount between the polishing bristles and the wooden component surface.

[0018] When the concentration value detected by the smoke concentration sensor is higher than a set value P2, the piston rod of the lifting cylinder retracts to reduce the contact amount between the polishing bristles and the surface of the wooden component, and P2>P1.

[0019] The material transmission mechanism comprises a driving cylinder fixedly mounted on the rear side of the material discharging end of the cover, and the piston rod end of the driving cylinder is arranged forward and fixedly connected with a clamping claw for fixing the wood component.

[0020] The polishing bristles are made of elastic metal wires.

[0021] The workbench is supported and installed by corresponding supporting feet.

[0022] Advantages of the present invention:

[0023] 1) The present invention adds a surface polishing mechanism to effectively perform surface polishing on the wood component before it enters the fire drying, thereby effectively improving the clarity of the concave and convex texture on the surface of the wood component; on this basis, the present invention further adds a material blocking mechanism to block the wood chips formed by the polishing of the wood component from falling back to the surface of the wood component, so that most of the wood chips are stored in the concave parts of the concave and convex texture on the surface of the wood component. In this way, when it enters the surface fire drying mechanism for fire drying, the wood chips on the surface of the wood component can be ignited simultaneously during the fire drying, so that the concave parts of the concave and convex texture on the surface of the wood component can also be fully fire dried, thereby effectively improving the surface fire drying uniformity of the wood component, and greatly improving the surface aging effect of the wood component.

[0024] 2) The material baffle mechanism of the present invention includes a material baffle plate obliquely arranged between the surface polishing mechanism and the surface roasting mechanism, the front end of the material baffle plate is located on the rear side of the polishing shaft and abuts against the polishing bristles located on the rear side of the polishing shaft, and the rear end of the material baffle plate is arranged with a gap between the surface of the wooden component. In this way, the wood chips formed by polishing can be concentrated and effectively fall back to the surface of the wooden component, and the wood chips remaining on the polishing bristles can be blocked, thereby ensuring the concentrated reflux effect of the wood chips formed by polishing, thereby ensuring the practical effect of the present invention.

[0025] 3) The present invention further fixes a set of lifting cylinders on the cover on the upper side of the polishing shaft. The height of the surface polishing mechanism is controlled by the lifting cylinders, and the smoke concentration generated by the surface fire drying operation is detected by the smoke concentration sensor. When the concentration value detected by the smoke concentration sensor is lower than the set value P1, it can be judged that the amount of sawdust generated by polishing is small. At this time, the piston rod of the lifting cylinder is controlled to extend to increase the contact amount between the polishing bristles and the surface of the wooden component, thereby improving the polishing effect; conversely, when the concentration value detected by the smoke concentration sensor is higher than the set value P2, it can be judged that the amount of sawdust generated by polishing is large. At this time, the piston rod of the lifting cylinder is controlled to retract to reduce the contact amount between the polishing bristles and the surface of the wooden component, thereby reducing the polishing effect. In this way, the polishing effect can be reasonably controlled to ensure the controllability of the surface aging effect of the wooden component.

[0026] 4) The material conveying mechanism of the present invention includes a driving cylinder fixedly installed on the rear side of the discharge end of the cover, and the piston rod end of the driving cylinder is arranged forward and fixedly connected with a wooden component fixing clamp, and the wooden component is fixed laterally by the wooden component fixing clamp to realize the transmission of the wooden component without causing mechanical damage to the surface of the wooden component, thereby further ensuring the practical effect of the present invention.

[0038] The material blocking mechanism 8 is arranged between the surface polishing mechanism and the surface roasting mechanism, and is used to block the wood chips formed by the surface polishing mechanism 5 polishing the wood component 4 and then fall back to the surface of the wood component 4;

[0039] The smoke exhaust mechanism 9 includes an air collecting hood 901 arranged on the upper side of the fire-roasting nozzle 602, and the air collecting hood 901 is connected to the feed end of the external exhaust gas treatment system through the corresponding exhaust pipe 902 and the exhaust fan 903.

[0040] By adding a surface polishing mechanism 5, the surface of the wood component 4 can be effectively polished before it enters the fire baking and drying, thereby effectively improving the clarity of the concave and convex texture on the surface of the wood component 4; on this basis, the present invention further adds a material blocking mechanism 8 to block the wood chips formed by the polishing of the wood component 4 from falling back to the surface of the wood component 4, so that most of the wood chips are stored in the concave parts of the concave and convex texture on the surface of the wood component 4. In this way, when it enters the surface baking mechanism 6 for fire baking and drying, the wood chips on the surface of the wood component 4 can be ignited simultaneously during the fire baking and drying, so that the concave parts of the concave and convex texture on the surface of the wood component 4 can also be fully formed by fire baking and drying, thereby effectively improving the surface baking and drying uniformity of the wood component, so as to greatly improve the surface aging effect of the wood component.

[0041] The material blocking mechanism 8 comprises a material blocking plate 801 obliquely arranged between the surface polishing mechanism 5 and the surface roasting mechanism 6, the front end of the material blocking plate 801 is located at the rear side of the polishing shaft 501 and abuts against the polishing bristles 503 located at the rear side of the polishing shaft 501, and the rear end of the material blocking plate 801 is arranged with a gap between the surface of the wooden component 4.

[0043] A group of lifting cylinders 10 are fixedly connected to the cover 2 on the upper side of the polishing shaft 501.

When the concentration value detected by the smoke concentration sensor 12 is lower than the set value P1, it can be judged that the amount of sawdust generated by polishing is small. At this time, the piston rod of the lifting cylinder 10 is controlled to extend to increase the contact amount between the polishing bristles 503 and the surface of the wooden component 4, thereby improving the polishing effect; conversely, when the concentration value detected by the smoke concentration sensor 12 is higher than the set value P2, it can be judged that the amount of sawdust generated by polishing is large. At this time, the piston rod of the lifting cylinder 10 is controlled to retract to reduce the contact amount between the polishing bristles 503 and the surface of the wooden component 4, thereby reducing the polishing effect. In this way, the polishing effect can be reasonably controlled to ensure the controllability of the surface aging effect of the wooden component.
