[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] An embodiment of the present invention provides an intelligent single board drying production line, which includes: an insulation board support frame 1; the outer side of the insulation board support frame 1 is covered with an insulation board 11, and the cavity formed inside the insulation board 11 is a drying chamber; wherein, a single board drying bracket 2 is installed in the drying chamber, and a chain transmission assembly is arranged on the single board drying bracket 2, and the single board can circulate in the drying chamber through the chain transmission assembly; a plurality of groups of single board drying support assemblies for placing single boards are arranged in the drying chamber, and each group of single board drying support assemblies is connected to the chain transmission assembly; a driving assembly is installed on one side of the insulation board 11, and the chain transmission assembly can be driven to move through the driving assembly; a hot air inlet 12 and a hot air outlet 13 are respectively opened on the front surface of the insulation board 11, and the hot air inlet 12 is located above the hot air outlet 13, and insulation doors 14 are installed at both ends of the other side of the insulation board 11.

[0023] It should be noted that the insulation board support frame 1, as the core support structure of the intelligent veneer drying production line, plays an important role in fixing and supporting other components. The insulation board 11 tightly wrapped on the outside can not only effectively maintain the temperature of the drying chamber, but also significantly reduce heat loss. The cavity formed inside the insulation board 11 is the drying chamber, which is used to accommodate the veneer drying bracket 2 and other related components. The veneer drying bracket 2 is equipped with a chain transmission assembly, which achieves a uniform drying effect by allowing the veneer to circulate in the drying chamber. Multiple groups of veneer drying support assemblies arranged inside the chamber are used to place the veneer, and each group of support assemblies is connected to the chain transmission assembly to ensure that the veneer can circulate smoothly. In order to drive the movement of the chain transmission assembly, a drive assembly is installed on one side of the insulation board 11. At the same time, a hot air inlet 12 and a hot air outlet 13 are opened on the front surface of the insulation board 11 to ensure that the hot air can circulate in the drying chamber, thereby improving the drying efficiency. On the other side of the insulation board 11, insulation doors 14 are installed at both ends to open or close the drying chamber when needed, so as to facilitate the entry and exit of single boards or maintenance operations.

[0024] In an embodiment of the present invention, the chain transmission assembly includes bearing seats 21 respectively installed at both ends of the top of both sides of the single board drying bracket 2, and a bearing 22 is installed on the inner side of the bearing seat 21, and two sides relatively close to the two bearings 22 are connected with double-row sprockets 23, and the inner sides of the two relatively double-row sprockets 23 are commonly connected with a transmission shaft 24, and the two ends of the transmission shaft 24 extend to the inner side of the bearing 22 respectively, and two transmission shaft support seats 25 are installed on the outer side of the two transmission shafts 24, and each transmission shaft support seat 25 is connected to the single board drying bracket 2 on one side close to the single board drying bracket 2, and the inner top ends of the single board drying bracket 2 are rotatably connected with auxiliary Auxiliary double-row sprocket 26, two double-row sprockets 23 located on the same side in the length direction of the single board drying bracket 2 are meshed with the outer sides of the two auxiliary double-row sprockets 26 and are connected with a double-row chain 27. The driving assembly includes a motor bracket 4 installed on one side of the insulation board 11, and the motor bracket 4 is located on the side close to the hot air inlet 12. A support frame 41 is installed on the top of the motor bracket 4. The inner side of the support frame 41 is rotatably connected with a coupling 42. The side of the coupling 42 away from the support frame 41 penetrates the insulation board 11 and is connected to one end of the transmission shaft 24. A driving member for driving the coupling 42 to rotate is installed on the side of the support frame 41 away from the coupling 42.

[0025] It should be noted that the bearing seat 21 is installed at both ends of the top of both sides of the veneer drying bracket 2, and its function is to support and fix the bearing 22, thereby providing rotation support for the transmission shaft 24. The double-row sprocket 23 is connected to the inner side of the two opposite bearings 22, and realizes synchronous rotation through the transmission shaft 24. In order to further support and fix the transmission shaft 24 and ensure the stability of the entire structure, the transmission shaft support seat 25 is installed on the outer side of the transmission shaft 24 and connected to the veneer drying bracket 2. The auxiliary double-row sprocket 26 is rotatably connected to the inner top ends of the veneer drying bracket 2, and works together with the double-row sprocket 23 to drive the movement of the double-row chain 27. The double-row chain 27 is meshed and connected to the outer sides of the two double-row sprockets 23 and the two auxiliary double-row sprockets 26 located on the same side of the length direction of the veneer drying bracket 2, and the cyclic movement of the chain is realized by the rotation of the sprocket, thereby driving the veneer to circulate in the drying chamber. The motor bracket 4 is installed on one side of the insulation board 11, close to the hot air inlet 12, for supporting and fixing the support frame 41. The support frame 41 is installed on the top of the motor bracket 4 to provide support for the coupling 42. The coupling 42 is rotatably connected to the inner side of the support frame 41, and the side away from the support frame 41 passes through the insulation board 11 and is connected to one end of the transmission shaft 24, thereby realizing power transmission. The driving member is a combination of an electric motor and a reducer, which is installed on the side of the support frame 41 away from the coupling 42, and is used to drive the coupling 42 to rotate. The rotation of the coupling 42 then drives the transmission shaft 24 and the double-row sprocket 23 to rotate, and finally drives the movement of the double-row chain 27 to realize the circulation drying of the single board in the drying chamber.

[0026] In an embodiment of the present invention, guide rails 3 are provided on the outer bottom and inner top of the outer chain of the double-row chain 27, the relatively distant sides of the two guide rails 3 are connected to the inner side of the single board drying bracket 2, the top of the guide rail 3 is located between the inner chain plates of the chain, and top guide rod support seats 31 are installed on the top side of both sides of the single board drying bracket 2, and the relatively close sides of the two top guide rod support seats 31 are installed with rail top guide rods 32, and the bottom of the rail top guide rod 32 is located between the inner chain plates of the chain.

[0027] It should be noted that the guide rail 3 is arranged at the outer bottom and inner top of the outer chain of the double-row chain 27. The two guide rails 3 are relatively far from each other and are connected to the inner side of the single board drying bracket 2 to provide guidance and support for the chain. The top of the guide rail 3 is located between the inner chain plates of the chain to ensure the stability of the chain during operation. The top guide rod support seat 31 is installed on the top side of both sides of the single board drying bracket 2 to support the top guide rod 32. The top guide rod 32 is installed on the side relatively close to the two top guide rod support seats 31, and its bottom is located between the inner chain plates of the chain. The top guide rod 32 works together with the guide rail 3 to provide additional guidance and support for the chain to ensure that the chain does not deviate or jump during operation. By setting the guide rail 3 and the top guide rod 32, the present invention can effectively improve the operating stability of the double-row chain 27, reduce the wear and failure rate of the chain, and thus extend the service life of the equipment. At the same time, the stable chain operation can also ensure the smooth transportation of the single board in the drying chamber, and improve the drying efficiency and quality.

[0028] In an embodiment of the present invention, the single board drying support assembly includes a connecting cross bar 5, and the connecting cross bar 5 is located above the two double-row sprockets 23, and chain link plates 51 are connected to both ends of the connecting cross bar 5, and the relatively far sides of the two chain link plates 51 are respectively connected to the outer sides of the two double-row chains 27, and connecting vertical rods 52 are connected to both ends of the connecting cross bar 5, and the bottoms of the two connecting vertical rods 52 relatively close to one side are rotatably connected to support frames 53, and the bottoms of the two support frames 53 relatively close to one side are commonly connected to a supporting steel grid 54, and the top sides between the two support frames 53 are commonly connected to a supporting cross bar 55, and a plurality of single board partition frames 56 are connected to one side of the supporting cross bar 55, and the single board partition frame 56 has a bending portion, and the end of the single board partition frame 56 away from the supporting cross bar 55 is connected to the top side of the supporting steel grid 54.

[0029] It should be noted that the connecting crossbar 5 is located above the two double-row sprockets 23, and serves as a transverse connector of the entire support assembly, playing a key connecting and supporting role. The chain link plate 51 is connected to both ends of the connecting crossbar 5, and its relatively distant side is respectively connected to the outer sides of the two double-row chains 27. Through this connection method, the entire support assembly can circulate with the movement of the double-row chains 27, so as to achieve uniform heating and drying of the single board in the drying chamber. The support frame 53 is installed at the bottom of the relatively close side of the two connecting vertical rods 52 by a rotational connection. The support frame 53 is allowed not to flip when the support assembly rotates with the double-row chains 27. Due to the rotational connection between the support frame 53 and the connecting vertical rod 52, when the chain drives the entire support assembly to circulate, the support frame 53 can remain stable under the action of its own gravity. The support frame 53 can also automatically adjust its posture through the action of gravity to ensure that the supporting steel grid 54 always remains in a horizontal state. In this way, the veneers placed on the supporting steel grid 54 will not move or fall due to the flipping or tilting of the supporting assembly, thereby ensuring the stability and safety of the drying process. The supporting crossbar 55 is connected to one side of the top between the two supporting frames 53 to provide support for the veneer separator 56. The veneer separator 56 is connected to one side of the supporting crossbar 55 and has a bending portion. Its end away from the supporting crossbar 55 is connected to one side of the top of the supporting steel grid 54. The main function of the veneer separator 56 is to separate the veneers to ensure that each veneer can be placed independently to avoid mutual contact and adhesion, thereby improving the drying effect and quality.

[0030] In an embodiment of the present invention, a plurality of single board partition frames 56 are evenly distributed on the supporting steel grid frame 54 , and a single board is placed between every two adjacent supporting steel grid frames 54 .

[0031] It should be noted that the evenly spaced single board partitions 56 can evenly space the single boards, ensuring that the same spacing is maintained between each single board. This can avoid contact and adhesion between single boards, and improve the drying effect. Due to the evenly spaced single board partitions 56, each single board can be stably placed on the supporting steel grid 54, and will not be unstable or tilted due to inconsistent spacing. The evenly spaced single board partitions 56 provide a uniform channel for hot air, ensuring that hot air can evenly pass through each single board, improving the uniformity and efficiency of drying.

[0032] The working principle of the intelligent veneer drying production line provided by the present invention is as follows: the supporting foundation of the production line is an insulation board support frame 1, and the insulation board 11 coated on the outside thereof effectively maintains the temperature of the drying chamber and reduces heat loss. High-temperature air is continuously blown into the hot air inlet 12 through an external device. The veneer drying bracket 2 installed in the drying chamber is equipped with a chain transmission assembly. By starting the driving assembly (including a motor, a reducer and a coupling), the transmission shaft 24 drives the double-row sprocket 23 to rotate, thereby driving the double-row chain 27 to circulate. The veneer drying support assembly (including the connecting cross bar 5, the chain link plate 51, the connecting vertical rod 52, etc.) can be circulated to ensure that the veneer is evenly heated in the drying chamber. The veneer is placed on the supporting steel grid 54 and separated by the equidistantly distributed veneer partition frames 56 to ensure that each veneer is independently and evenly heated. The rotating connection design of the support frame 53 ensures that the supporting steel grid 54 always remains horizontal to prevent the veneer from moving or falling. The guide rail 3 and the guide rod 32 at the top of the rail provide guidance and support for the double-row chain 27, ensuring stable operation of the chain and reducing wear and failure.

[0033] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0034] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
