TECHNICAL FIELD
[0001] The present application relates to the technical field of single-sided hot pressing of wood panel veneer, and in particular to a pressing plate structure of a wood panel veneer hot press. BACKGROUND
[0002] Veneered panels are panels made by attaching a decorative layer of the same or different material to one end face of a panel made of wood or bamboo material, etc. with varying thickness. They can be used in home decoration, commercial premises, medical and health care fields, and have the characteristics of beauty, environmental protection and cost savings.
[0003] In production, most enterprises use veneer hot presses to hot-press the veneer of wood panels. The structure of the veneer hot press generally consists of a fixed bottom plate and an upper and lower moving hot press plate. The wood panel is placed on the bottom plate, and then the top surface of the wood panel is placed on the fixed veneer to be hot-pressed. After a certain period of time, the hot press plate is moved upwards and separated from the wood panel, thereby achieving hot pressing of the veneer layer of the veneered panel, and the veneered panel is removed from the bottom plate.
[0004] Obviously, the veneer hot press described above has a relatively low hot pressing efficiency for veneer. Then, a veneer hot press similar to the patent with application number 202222649604.1 appeared on the market. It consists of multiple layers of hot press plates distributed above and below. The lowermost hot press plate is below the bottom plate. The hot press plates can move up and down. The wood panels are placed on the top surface of the adjacent hot press plate or the top surface of the bottom plate below each layer of hot press plate, and then the top surface of the wood panel is placed on the fixed veneer to be hot-pressed. Then, control the downward movement of each layer of hot press plate to hot-press the veneer of each layer of wood panel, thereby achieving hot pressing of the veneer layer of multiple veneered panels at a time, effectively improving the production efficiency.
[0005] Although the surface of the veneer layer hot-pressed by the current veneered panel has various wood grain patterns, since the veneer is usually rotary cut wood veneer or directly veneer decorative paper, after hot pressing, the wood grain of the rotary cut wood veneer is almost not felt, and the veneer decorative paper is completely flat and smooth, and the wood grain pattern printed on the veneer decorative paper has no real wood grain effect.
[0006] Therefore, in order to simulate the concave-convex feeling of the real wood panel surface texture, some veneered panels are pressed again after hot pressing to make the surface of the veneer layer have corresponding indentations according to the veneer layer pattern, so that the veneer layer of the veneered panel is closer to solid wood in terms of hand feeling.
[0007] Obviously, this requires an additional pressing process, which increases production costs and production cycle.
[0008] If the bottom surface of the hot press plate in the veneer hot press of the above patent with application number 202222649604.1 is directly set as a directly heated mold pressing plate, it is theoretically possible. However, if the enterprise produces more products and the texture changes more, it will lead to the enterprise needing to configure more hot press plates with different textures on the bottom surface to adapt to production. However, the cost of configuring more hot press plates with different textures is relatively high, and the hot press plate is generally heated with oil. When replacing, not only the disassembly and assembly of the plate body itself are involved, but also the disassembly and assembly connection of the heat conduction oil circuit are involved. The temperature of the heat conduction oil is very high (about 200 degrees Celsius). In order to improve the replacement efficiency as much as possible, the disassembly and assembly replacement can only be directly carried out without reducing the temperature of the heat conduction oil, but this will have safety hazards. If safety is to be ensured, the replacement needs to be carried out after the oil temperature of the heat conduction oil is reduced to a safe temperature (below 45 degrees Celsius), but this will obviously seriously affect the replacement efficiency, and after replacement, the oil temperature needs to be raised to the required temperature before continuing production, which will continue to prolong the replacement time and also cause additional energy consumption.
[0009] Therefore, only the structure of the hot press plate bottom detachably fixedly connected with the mold pressing plate can be adopted.
[0010] In addition, the technical solution of the above patent with application number 202222649604.1 also has the problem that the heat release of the hot press plate cannot be unidirectional to the veneer layer of the wood board below the hot press plate, but will be released upward and downward respectively, which leads to the fact that the heat of the hot press plate cannot be completely used for hot pressing of the veneer layer, resulting in relatively high unit energy consumption of the hot press veneer plate and the hot press plate. In addition, since the wood board of the veneer plate except the lowermost veneer plate is placed above the hot press plate, the heat of the hot press plate will directly act on the bottom surface of the wood board, thereby performing secondary hot pressing on the bottom of the wood board, further leading to the fact that the thickness of the wood board of the veneer plate as a whole becomes smaller, the strength structure of the end of the wood board away from the veneer layer changes and becomes more compact, and the overall strength balance of the wood board is destroyed. Moreover, the contact between the hot press plate or the bottom plate and the upper and lower end surfaces of the wood board in the above structure is direct and purely rigid contact, and the hot pressing of the veneer layer is indeed secondary hot pressing relative to the wood board of the veneer plate. Therefore, once the wood board is unevenly stressed or the top or bottom surface of the wood board is locally stressed too much, cracks or even fractures will occur in the base material originally hot pressed and fixed as a whole in the wood board, affecting the strength of the wood board.

[0042] The connecting vertical plate 10 is respectively provided with a vertical strip-shaped through hole 20 corresponding to the position of the connecting bolt C19.
[0043] The heat-conducting elastic layer 5 is a woven fabric woven by the heat-conducting rubber thread 21 in the warp direction and the heat-conducting fiber 22 in the weft direction.
[0044] The heat insulation layer 8 is an asbestos cloth.
[0045] The size of the die plate 4 and the size of the base plate 7 are matched with the size of the hot press plate 1; the size of the heat-conducting elastic layer 5 is larger than the size of the hot press plate 1 and completely covers the bottom surface of the hot press plate 1; and the size of the heat insulation layer 8 is larger than the size of the hot press plate 1 and completely covers the top surface of the hot press plate 1.
[0046] The left and right side walls of the hot press plate 1 are respectively provided with the lifting guide plate 2 connected with the hot press.
[0047] The left and right two side edges of the heat-conducting elastic layer 5 are located between the corresponding side edges of the hot press plate 1 and the side edges of the lifting guide plate 2 away from the hot press plate 1, and the front and rear two side edges of the heat-conducting elastic layer 5 are located between the corresponding side edges of the hot press plate 1 and the corresponding flange A12 of the connecting side plate 3.
[0048] The left and right side edges of the heat insulation layer 8 are located between the corresponding side edges of the hot press plate 1 and the side edges of the lifting guide plate 2 away from the hot press plate 1.
[0049] The base plate 7 comprises horizontal plates 16 arranged in parallel, and the horizontal plates 16 are connected and fixed by vertical studs 17 arranged in a crisscross manner. The vertical studs 17 are uniformly provided with a plurality of air holes 18 on the stud plates.
[0050] The top edge of the connecting vertical plate 10 is connected with the front and rear side edges of the horizontal plate 16 located at the bottom of the base plate 7.
[0051] The base plate 7 and the heat insulation layer 8 are further provided with an elastic buffer layer 9, and the material of the elastic buffer layer 9 is rubber pad.
[0052] When the elastic buffer layer 9 is compressed and deformed under pressure, the front and rear side edges of the elastic buffer layer 9 are within the range of the front and rear side edges of the base plate 7.
[0053] In combination Figure 2 And Figure 3 It can be seen that the heat-conducting elastic layer 5 is a woven fabric woven by the longitudinal heat-conducting rubber thread 21 and the weft heat-conducting fiber 22. The heat-conducting rubber thread 21 is arranged flat, and each heat-conducting fiber 22 is twisted up and down on the heat-conducting rubber thread 21.
[0054] The material of the heat-conducting rubber thread 21 is rubber added with boron nitride or aluminum oxide (for example, the rubber disclosed in the technical solution of the patent with the application number 201610580449.9 can be used).
[0055] The material of the heat-conducting fiber 22 is para-aramid fiber.
[0056] The heat-conducting rubber thread 21 is a tubular rubber thread 23, and a copper wire 24 is fixedly arranged in the tubular rubber thread 23.
[0057] The thickness of the tube wall of the tubular rubber thread 23 is greater than or equal to the radius of the copper wire 24.
[0058] The heat-conducting fiber 22 comprises heat-conducting fiber units A 221 twisted up and down on adjacent two heat-conducting rubber threads 21 and heat-conducting fiber units B 222 twisted up and down on adjacent two groups of heat-conducting rubber threads 21.
[0059] The adjacent two heat-conducting fiber units A 221 form a heat-conducting fiber group A, and the adjacent two heat-conducting fiber units B 222 form a heat-conducting fiber group B. The heat-conducting fiber group A and the heat-conducting fiber group B are arranged in a staggered manner along the extension direction of the heat-conducting rubber thread 21.
[0060] The heat-conducting fiber group A includes two heat-conducting fiber units A221, and the heat-conducting fiber units A221 in the same heat-conducting fiber group A are alternately wound on the adjacent two heat-conducting rubber wires 21.
[0061] The heat-conducting fiber group B includes two heat-conducting fiber units B222, and the two heat-conducting fiber units B222 in the same heat-conducting fiber group B are alternately wound on the adjacent two groups of heat-conducting rubber wires 21, and each group of heat-conducting rubber wires 21 includes two heat-conducting rubber wires 21.
[0062] The two heat-conducting rubber wires 21 wound by the heat-conducting fiber group B each time are the adjacent two heat-conducting rubber wires 21 belonging to different groups among the adjacent two groups of heat-conducting rubber wires 21 wound by the heat-conducting rubber wires 21 of another heat-conducting fiber group B adjacent to the heat-conducting fiber group B.
[0063] Through the weaving structure of the heat-conducting rubber wires 21 and the heat-conducting fibers 22 and the structure and material of each of them, the heat-conducting elastic layer 5 can not only have good heat-conducting performance, but also have good elastic effect.
[0064] The weaving structure of the heat-conducting rubber wires 21 and the heat-conducting fibers 22, because the heat-conducting fiber units A221 in the same heat-conducting fiber group A are alternately wound on the adjacent two heat-conducting rubber wires 21, can not only ensure that each adjacent heat-conducting rubber wire 21 in the warp direction can be woven and fixed, but also because the heat-conducting fiber units B222 are alternately wound on the adjacent two groups of heat-conducting rubber wires 21, so that the connection tightness of each heat-conducting rubber wire 21 in the corresponding area of each group of heat-conducting rubber wires 21 wound by the heat-conducting fiber units B222 is relatively looser and has a larger deformation allowance, which facilitates the relatively small force of the heat-conducting rubber wires 21 on the heat-conducting fiber units B222 after the heat-conducting rubber wires 21 are deformed under pressure, and avoids damage to the heat-conducting fiber units B222 due to excessive pressure.
[0065] The heat-conducting rubber wires 21 are in the structure of the tubular rubber wire 23 with the copper wire 24 fixedly arranged therein, so as to ensure that the heat-conducting rubber wires 21 have a certain rigid supporting force, and further improve the heat-conducting performance of the heat-conducting rubber wires 21.
[0066] The heat-conducting fibers 22 are alternately wound on each flatly arranged heat-conducting rubber wire 21, so as to further ensure the flatness of the woven fabric, which is conducive to heat conduction and reduces the gap formed by the bending of the heat-conducting rubber wires 21, so that the heat is retained in the gap and the heat-conducting performance is reduced.
[0067] The thickness of the tubular wall of the tubular rubber wire 23 is greater than or equal to the radius of the copper wire 24, so as to ensure the elastic effect of the heat-conducting elastic layer.
[0068] The heat-conducting fibers 22 are sequentially and alternately wound on the heat-conducting rubber bands 21, thereby further ensuring the flatness of the woven fabric, and further facilitating the heat conduction and reducing the heat retention in the gaps caused by the bending of the heat-conducting rubber bands 21, and thus reducing the heat conduction performance.
[0069] The two heat-conducting fiber units B222 of the adjacent heat-conducting fiber group B are wound on the heat-conducting rubber bands 21 in a staggered manner, so that the woven structure of the heat-conducting fibers and the heat-conducting rubber bands is more uniform, and the connection between the adjacent heat-conducting rubber bands is also more uniform and stable.
[0070] In the installation of the present application, the connecting side plate 3 is first connected and fixed with the side wall of the hot-pressing plate 1 through the connecting bolts A11; then the heat-conducting elastic layer 5 is laid on the top surface of the mold pressing plate 4, and the flange B14 of the mold pressing plate 4 is clamped and fixed with the flange A12 of the connecting side plate 3 through the connecting clamps 6, the connecting clamps 6 are sequentially and equidistantly arranged along the extension direction of the flange B14, and the both ends of the flange B14 are respectively provided with the connecting clamps 6; then the heat insulation layer 8 is laid on the top surface of the hot-pressing plate 1, and the elastic buffer layer 9 is laid thereon, the base plate 7 is then placed on the elastic buffer layer 9, and the connecting vertical plate 10 of the base plate 7 is connected and fixed with the connecting side plate 3 through the connecting bolts C19.
[0071] When the hot press is used, the hot press is provided with multiple layers of hot pressing plates 1, and the wood board is placed between two adjacent layers of hot pressing plates 1. When the wood board is placed, the end surface of the wood board away from the veneer layer is placed on the base plate 7 of the lower hot pressing plate 1 in the two adjacent layers of hot pressing plates 1, and the wood board is completely located within the range of the base plate 7, the veneer layer of the wood board faces upward and faces the mold pressing plate 4 of the upper hot pressing plate 1 in the two adjacent layers of hot pressing plates 1; after the wood board is placed between the two adjacent layers of hot pressing plates 1, the hot press performs hot pressing on the wood board between the hot pressing plates 1 through the hot pressing plates 1; during hot pressing, the mold pressing plate 4 of the upper hot pressing plate 1 presses downward relative to the wood board, and when the wood board is pressed by the mold pressing plate 4, the reaction force of the wood board on the mold pressing plate 4 will cause the heat-conducting elastic layer 5 to be deformed under pressure, and the wood board will also conduct the downward pressure of the mold pressing plate 4 to the base plate 7 below the wood board, causing the elastic buffer layer 9 below the base plate 7 to be deformed under pressure. Through the deformation of the heat-conducting elastic layer 5 and the elastic buffer layer 9 under pressure, the force exerted by the bottom surface of the mold pressing plate 4 and the top surface of the wood board and the top surface of the base plate 7 and the bottom surface of the wood board can always be uniformly exerted, and complete contact between them can also be ensured; further, the embossing layer 13 of the bottom surface of the mold pressing plate 4 can fully contact and press the veneer layer on the top surface of the wood board, so that the embossing layer 13 can fully press the veneer layer on the top surface of the wood board to form the texture effect that can be pressed. Through the action of the heat insulation layer 8, the heat released from the top surface of the hot pressing plate 1 below the wood board can be blocked from being conducted upward and insulated, so that the heat of the hot pressing plate 1 is conducted downward to the corresponding mold pressing plate 4 as much as possible; through the structure of the base plate 7, the vertical ribs 17 not only reduce the self-weight of the base plate 7, but also form multiple interconnected heat insulation cavities between the horizontal plates 16 of the base plate 7 through the air holes 18 provided on the rib plates of the vertical ribs 17, further blocking the heat of the hot pressing plate 1 below the wood board from being transmitted upward to the bottom surface of the wood board; through the structure of the heat-conducting elastic layer 5, the elastic layer is formed between the mold pressing plate 4 and the hot pressing plate 1 to ensure that the mold pressing plate 4 and the wood board can be safely and fully in contact, and more importantly, the heat-conducting elastic layer 5 is a woven fabric woven from the longitudinal heat-conducting rubber cord 21 and the weft heat-conducting fiber 22, especially the heat-conducting rubber cord 21 is a tubular rubber cord 23 with a copper wire 24 inside, which can also ensure the heat conduction effect between the hot pressing plate 1 and the mold pressing plate 4, so that the heat generated by the hot pressing plate 1 above the wood board can be conducted to the mold pressing plate 4 as much as possible, and the veneer layer on the top surface of the wood board is pressed by the embossing layer 13 of the mold pressing plate 4 to form the required texture, thereby improving the realism of the veneer layer of the wood board.
