Description

Technical Field

[0001] The present application relates to the technical field of processing fir ecological board cores, and in particular to a hot pressing device for producing fir ecological board cores. Background Art

[0002] The wood of fir is yellow-white, and sometimes the heartwood is light reddish-brown. It is soft, delicate, fragrant, with straight texture and easy to process. It has a specific gravity of 0.38, is resistant to decay, and is not eaten by termites. It is used for construction, bridges, shipbuilding, mine pillars, wooden piles, electric poles, furniture and as raw materials for the wood fiber industry.

[0003] Chinese fir is sometimes processed into the core material of man-made boards. The core board, also known as the middle board or short middle board, is the inner layer of veneer with a grain perpendicular to the grain of the surface board. During processing, Chinese fir is hot-pressed to increase the density of the board.

[0004] When the fir ecological board core is hot-pressed, the board core to be processed is transported to the hot press, and the placed board core is hot-pressed by the upper and lower hot pressing plates in the hot press. When the hot pressing is completed, the lower hot pressing plate drives the board core to move downward until it is aligned with the board core on the input conveyor belt, and under the push of the subsequent board core input, the hot-pressed board core can be moved toward the end along the length direction of the lower pressing plate under the action of thrust.

[0005] During the hot pressing process of the fir ecological board core, workers often directly stack or transport the board cores output from the hot press, which can easily cause the fir ecological board core to crack or deform due to internal stress. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0022] In this embodiment, the hot pressing section 10 includes a frame 11, an upper hot pressing plate 12, a lower hot pressing plate 13 and a plurality of lifting hydraulic cylinders 14. The upper hot pressing plate 12 is supported and fixed at a certain height by the frame 11, and a plurality of lifting hydraulic cylinders 14 are installed at the bottom of the frame 11, and the plurality of lifting hydraulic cylinders 14 drive the lower hot pressing plate 13 to be movable below the upper hot pressing plate 12. The upper hot pressing plate 12 and the lower hot pressing plate 13 can be heated by steam, and the hot pressing plate and the oil inlet pipeline are connected by a high-pressure hose, and a temperature measuring device can also be installed on the hot pressing plate. The input conveyor belt can transport the fir ecological board core to be hot-pressed to the lower hot pressing plate 13 for support. Driven by the lifting hydraulic cylinders 14, the lower hot pressing plate 13 can make the fir ecological board core to be hot-pressed contact with the upper hot pressing plate 12 and the lower hot pressing plate 13 respectively for hot pressing treatment. After the hot pressing treatment is completed, the lower hot pressing plate 13 drives the fir ecological board core to move to the same horizontal plane as the board core on the input conveyor belt, and then the board core on the input conveyor belt can push the treated board core on the lower hot pressing plate 13 to be transported to the output cooling part 20 during input.

[0023] In this embodiment, the output cooling section 20 includes a support frame 21, two sets of conveyor belts 22, an air supply assembly 23 and at least one set of flap assemblies 24. The two sets of conveyor belts 22 are respectively installed on opposite sides of the support frame 21 and driven by a conveying motor. Support plates 211 for supporting the conveyor belts 22 are formed on the inner walls on both sides of the support frame 21. Each set of conveyor belts 22 is connected to a transmission wheel 221 at least at its inner ends. The two sets of conveyor belts 22 can support the board core and transport it to the end. At least one set of flap assemblies 24 is set between the two sets of conveyor belts 22, and the flap assemblies 24 are used to flip the board core during the transportation process of the two sets of conveyor belts 22. The air supply assembly 23 is installed on the inner bottom of the support frame 21, and the air supply assembly 23 can supply air to the board core transported by the two sets of conveyor belts 22, so that it is cooled during the transportation process.

[0024] See Figure 3 and Figure 4The flap assembly 24 includes a motor 241, a swing arm 242, a first drive arm 243, a second drive arm 244, a first core bracket 245, a second core bracket 246, and a positioning bracket 247.
