[0002] Solid wood boards are widely used in building construction fields such as home decoration due to their environmental protection performance, natural texture, and durability. However, due to the uneven internal structure of wood and the differences in radial and tangential shrinkage rates, solid wood boards will deform when soaked or dehydrated, easily causing the boards to fall off or shift, affecting the safe use of the boards.

[0003] In the prior art, to ensure the safe use of boards, hot presses are usually used to press the boards into the form of multi-layer solid wood. The invention patent with the authorization announcement number CN116985503B provides a hot pressing and cooling integrated composite machine, including a main body component, a hot pressing structure, and a cooling structure; the hot pressing structure is fixedly arranged inside the main body component, the cooling structure is fixedly arranged on the right side of the main body structure and is opposite to the hot pressing structure; through the hot pressing structure of the present invention, multiple boards can be pressed and formed at one time, improving the overall pressing efficiency; the pressed boards can be moved to the cooling structure for cooling and heat dissipation, avoiding scalding and the influence of stacking on heat dissipation and adhesion quality; and double-sided heat dissipation of the boards can be achieved; with the help of the cooling structure, cooling can be achieved simply by blowing air with a fan, and double-sided accelerated cooling and temperature reduction of the boards can be realized by flipping the boards; cold water supply equipment can also be connected to cool the cooling box, and the cooling effect can be enhanced by blowing air and contacting the boards.

[0004] In the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: Although the multi-layer solid wood boards produced by the patented technology improve the moisture-proof performance of the boards, thin boards need to be made first, and then the thin boards are glued and spliced and then pressed, with complex processes and environmental protection hazards. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention develops a safe board pressing device, which can perform moisture-proof treatment on single-layer solid wood boards, omitting complex processes such as making thin boards, splicing, applying adhesives, and pressing, reducing costs, and being more environmentally friendly without using adhesives.

[0006] The technical solution for the present invention to solve the technical problem is as follows: An embodiment of the present invention provides a safe plate pressing device, which includes a hydraulic cylinder, a top plate, a base plate, a lower plate, an upper plate, a pressing die, and columns. The top plate is arranged above the base plate. The columns are vertically arranged between the top plate and the base plate, with one column respectively arranged at the four corners of the top plate. The upper end of the column is connected to the bottom surface of the top plate, and the lower end of the column is connected to the top surface of the base plate. The hydraulic cylinder is installed upside down on the top plate, and the telescopic rod of the hydraulic cylinder passes through the top plate and is connected to the upper plate. The lower plate is arranged on the base plate, and the lower plate is directly below the upper plate. The pressing die is arranged on the lower plate.

The cushion frame is a square frame shape and is arranged between two die boxes. The pressing plate is arranged on the top of the uppermost die box. The lowermost die box is connected to the pressing plate by bolts. An interface is arranged on the side surface of the die box. Grooves are arranged on the bottom surface and side surface of the inner cavity of the die box, the bottom surface of the die box, the inner side of the cushion frame, and the bottom surface of the pressing plate. The interface on the side surface of the die box is communicated with the grooves on the side surface and bottom surface of the inner cavity of the die box. The groove on the side surface of the inner cavity of the die box is communicated with the groove on the pressing plate or the bottom surface of the die box above this die box. The interface on the side surface of the die box is connected to a high-pressure water source or a hot gas source through a pipeline, and a valve is arranged on the pipeline connecting the interface and the high-pressure water source or the hot gas source.

[0007] As an optimization, the size of the cushion frame corresponds to the size of the top frame of the die box.

[0008] As an optimization, a pressure gauge is arranged on the pipeline connecting the valve and the high-pressure water source or the hot gas source. The valve is a manual control valve. After the numbers on the pressure gauge are stable, it indicates that the resistance of the solid wood to the water pressure reaches stability, and it is speculated that the solid wood is saturated by soaking.

The upper top block is installed on the bottom surface of the upper plate, the lower top block is installed on the top surface of the lower plate, the spring is installed on the top of the lower top block, and the upper top block corresponds to the lower top block.

[0012] As an optimization, a pressing block is further arranged on the bottom surface of the upper plate, and the size of the pressing block corresponds to the size of the top surface of the pressing die. The pressing block only contacts the top surface of the pressing die and can avoid the bolts and pipelines around the pressing die.

[0013] As an optimization, a plurality of interfaces are evenly arranged on both sides of the die box, and a plurality of bolt connection holes are arranged at the front and rear ends of the die box.

[0014] As an optimization, the cushion frame includes a right cushion frame and a left cushion frame. Both the right cushion frame and the left cushion frame are U-shaped. The connection part of the right cushion frame and the left cushion frame is an insertion interface. A bolt connection hole is respectively arranged on the right side of the right cushion frame and the left side of the left cushion frame. Each left cushion frame is connected into one body by bolts, and each right cushion frame is connected into one body by bolts.

[0015] The effects provided in the invention content are only the effects of the embodiments, rather than all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0016] 1. The device can perform moisture-proof treatment on single-layer solid wood boards. By setting a pressing die, and the thickness of the single-layer solid wood board is less than or equal to the depth of the inner cavity of the die box plus the thickness of the cushion frame. After putting the single-layer solid wood board into the pressing die for shaping and then soaking it in water, the force causing the wood board to deform is released into its own interior, promoting uniform dry shrinkage rate inside the wood board. Then the wood board is compressed and dried to make its internal structure dense and improve the strength. Then soak and dry it several times to release the internal stress. Obtain solid wood boards with high strength and uniform internal dry shrinkage rate, omitting complex processes such as making thin boards, splicing, applying adhesives, and pressing, reducing costs, and being more environmentally friendly without using adhesives.

[0017] 2. By setting the cushion frame, it can not only realize the shaping of the single-layer solid wood board by the pressing die, but also, after removing the cushion frame, shape the solid wood board when compressing it. One-time fixation can complete the treatment of the solid wood board, without the need to replace the mold and disassemble and assemble repeatedly, improving work efficiency.

[0018] 3. By setting the upper ejector rod and the lower ejector rod, the maximum downward pressing depth of the hydraulic cylinder can be limited to ensure the safety of the pressing die.

[0019] 4. By setting the upper top block, spring, and lower top block, the descending speed of the upper plate can be buffered to avoid impact damage to the equipment.

[0020] 5. By setting the cushion frame in the combined form of a right cushion frame and a left cushion frame, and arranging bolt connection holes on its side, multiple right cushion frames or left cushion frames can be disassembled at one time to achieve rapid removal of the cushion frame. By setting the connection part of the right cushion frame and the left cushion frame as an insertion interface, the sealing performance of the cushion frame can be improved.
