Description

Technical Field

[0001] The present invention relates to the technical field of printing plates, and more particularly to a 3D wood grain printing plate and a production method thereof. Background Art

[0002] Currently, 3D wood-grain printed panels create a 3D visual effect by coating a 3D wood-grain layer on top of the printed layer. This effect is also enhanced by a convex structure on the printed layer, creating a stronger sense of three-dimensionality on the wall. To reduce production costs, the convex portions of the printed layer are formed with perforations on the reverse side. During production, before the glue is fully cured, the perforations in the printed layer are prone to debonding from the base board. Pressing at these locations can easily cause the convex structures of the printed layer to deform. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a 3D wood grain printed board and a production method thereof, which can reduce the degumming phenomenon and have a heat preservation effect.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a D wood grain printing board, comprising a substrate and a printing board layer, the substrate comprising an end face one, the printing board layer comprising an end face two, the end face one and the end face two being bonded and adhered, the printing board layer being provided with a plurality of protrusions on the side facing the end face two, the printing board layer being provided with a groove on the side away from the end face two, the groove and the protrusion being arranged correspondingly along the thickness direction of the printing board layer, an inserting plate being installed on the side of the substrate away from the printing board layer, the inserting plate being inserted into the substrate, the inserting plate comprising a raised portion close to the side of the printing board layer, the substrate being provided with a groove body two, the groove body two being connected to the groove, a sealing ring being installed on the circumferential side wall of the groove body two on the side away from the groove, the raised portion being inserted into the groove body two, a cushioning layer being installed on the side of the raised portion close to the printing board layer, the cushioning layer being partially inserted into the groove and filling the groove.

[0005] The present invention is further configured such that a groove body 1 is provided on a side of the substrate away from the end face 1, the groove body 1 is connected to the groove body 2, the inserting plate also includes a bottom plate on a side away from the end face 1, the bottom plate is inserted into the groove body 1, the groove body 1 is also inserted and installed with a pad, the pad is located at both ends of the groove body 1 in the length direction, the groove body 1 includes a wall surface located on a side close to the end face 1, the inserting plate includes an end face 4, and the end surfaces on both sides of the pad are respectively abutted against the end face 4 and the wall surface.

[0006] The present invention is further configured such that the length direction of the groove is arranged in the same direction as the length direction of the convex body, and the length of the groove is smaller than that of the convex body.

[0007] The present invention is further configured such that the protrusion passes through the sealing ring, and the inner peripheral wall surface of the sealing ring is in close contact with the outer peripheral wall surface of the protrusion.

[0008] The present invention is further configured such that the cushion layer is thermal insulation cotton.

[0009] The present invention is further configured such that the base plate further includes an end face three on a side away from end face one, and the end face three is flush with an end face of the inserting plate on a side away from end face one.

[0010] The present invention also adopts the following technical solution: a production method of a D wood grain printed board, comprising the following production steps:

[0011] ① Install a sealing ring on the outer periphery of the bottom of the second tank;

[0012] ②Insert the plug-in board into the base plate, insert the raised portion into the second groove, and ensure that the inner wall of the sealing ring is in close contact with the outer wall of the raised portion to form a seal;

[0013] ③ Bond the cushion layer to the raised portion, with the top of the cushion layer extending beyond the end face;

[0014] ④ After the end surface is coated with glue, the printing board layer is bonded, and the bottom surface of the printing board layer is bonded to the end surface. During the bonding process, the printing board layer presses the cushion layer, and the cushion layer is compressed;

[0015] ⑤ Insert pads on both sides of the trough body, and move the insert plate toward the side of end face three until the bottom plate is flush with end face three, and the pad layer rebounds to a free state.

[0016] The present invention is further configured such that, in step ②, the end face of the inserting plate on the side away from end face one extends into the slot body one.

[0017] The present invention is further configured such that the height of the cushion layer extending beyond the end surface 1 is greater than the depth of the groove.

[0018] In summary, the present invention has the following beneficial effects:

[0019] After the cushion layer expands, its internal pressure decreases, creating a pressure differential on both sides of the raised portion, tightening the bond between the printed board layer and the substrate and reducing the possibility of relative movement between the two. Any excess glue that can't be squeezed out is pressed into the grooves, resulting in a smoother surface after molding. Furthermore, because the raised portion has an arc-shaped cross-section, the pressure differential on both sides of the raised portion causes the raised portion to contract toward its rounded shape, reducing the risk of debonding between the two ends of the arc.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, this embodiment discloses a 3D wood grain printing plate, comprising a substrate 1 and a printing plate layer 2, wherein the printing plate layer 2 is a thin layer of aluminum plate. Figure 2 In the figure, the printed board layer 2 is located at the top of the substrate 1 and includes a second end surface 22 at the top, which is printed with 3D wood grain. The top of the printed board layer 2 is provided with multiple protrusions 21. The protrusions 21 have an arc-shaped cross-section and protrude upward along the second end surface 22. The protrusions 21 extend along the length of the second end surface 22 to form a long strip. The protrusions 21 are provided along the width of the second end surface 22 to create a more three-dimensional visual effect of the wood grain on the second end surface 22.

[0029] like Figure 2 As shown, the printing plate layer 2 is provided with a groove 211 on the side away from the second end surface 22, and the groove 211 and the protrusion 21 are arranged correspondingly along the thickness direction of the printing plate layer 2. Figure 2 In the figure, the groove 211 is located below the convex body 21, and the groove 211 extends upward along the bottom surface of the printing plate layer 2. The groove 211 is arranged one by one above and below the convex body 21. The length direction of the groove 211 is arranged in the same direction as the length direction of the convex body 21. The length of the groove 211 is smaller than the convex body 21, and the two ends of the length direction of the groove 211 do not pass through the printing plate layer 2.

[0030] like Figure 2As shown, the substrate 1 includes an end face 12 at the upper end and an end face 3 13 at the lower end. The end face 12 is attached to and bonded to the bottom surface of the printing plate layer 2. The substrate 1 is provided with a groove 11, which is recessed upward along the end face 3 13. The length direction of the groove 11 is in the same direction as the length direction of the protrusion 21. The two ends of the groove 11 in the length direction pass through the substrate 1. The substrate 1 is also provided with a groove 2 111, which is connected to the groove 2 111 and is combined with the groove 111. Figure 4 , the groove body 11 includes a wall surface 112, the wall surface 112 is the upper wall of the groove body 11, the groove body 2 111 extends upward along the groove body 11 and passes through the upper end of the substrate 1, and the groove body 2 111 is connected to the groove 211. Figure 5 As shown, the second slot 111 is a rectangular slot.

[0031] like Figure 2 、 Figure 3 、 Figure 4 As shown, a sealing ring 6 is installed on the circumferential side wall of the second tank body 111 away from the groove 211. The sealing ring 6 is a rubber sealing ring with a rectangular structure. Specifically, a recessed groove is provided on the circumferential side wall of the second tank body 111, and the sealing ring 6 is inserted into the recessed groove.

[0032] like Figure 2 As shown, an insert plate 3 is mounted on the side of the substrate 1 away from the printed board layer 2. The insert plate 3 is inserted into the substrate 1, with the third end surface 13 flush with the bottom surface of the insert plate 3. Specifically, the insert plate 3 includes a bottom plate 32 and a raised portion 31. The raised portion 31 extends upward from the upper end of the bottom plate 32. The bottom plate 32 is inserted into the first groove 11, and the raised portion 31 is inserted into the second groove 111. The raised portion 31 passes through the sealing ring 6, and the inner circumference of the sealing ring 6 is closely attached to the outer circumference of the raised portion 31.

[0033] like Figure 2 As shown, a cushion layer 5 is installed on one side of the raised portion 31 close to the printed board layer 2, and the bottom of the cushion layer 5 is bonded to the top of the raised portion 31. The cushion layer 5 is a thermal insulation cotton that plays a role in thermal insulation. The upper part of the cushion layer 5 is inserted into the groove 211 and fills the groove 211.

[0034] The trough body 11 is also inserted with a pad 4, which is located at both ends of the length direction of the trough body 11. The trough body 11 includes a wall 112 located on the side close to the end face 12. The insert plate 3 includes an end face 4 321 located at the upper end. The end faces on both sides of the pad 4 respectively abut the end face 4 321 and the wall 112.

[0035] The production method of the above-mentioned 3D wood grain printed board includes the following production steps:

[0036] ① A sealing ring 6 is installed on the outer periphery of the bottom of the second tank body 111.

[0037] ② Insert the insert plate 3 from the bottom of the base plate 1, insert the bottom plate 32 into the groove body 11, insert the raised portion 31 into the groove body 2 111, and fit the outer peripheral wall of the raised portion 31 with the circumferential wall of the groove body 2 111. The inner peripheral wall of the sealing ring 6 is in close contact with the outer peripheral wall of the raised portion 31 to form a seal. Figure 4 、 Figure 6 The upper end surface of the bottom plate 32 (i.e., the end surface 321) is close to but does not abut the upper wall surface of the trough body 11 (i.e., the wall surface 112). At this time, the lower end surface of the bottom plate 32 extends into the trough body 11.

[0038] ③ Bond the cushion layer 5 to the raised portion 31 , with the top of the cushion layer 5 extending beyond the end surface 12 , and the height of the cushion layer 5 extending beyond the end surface 12 being greater than the depth of the groove 211 .

[0039] ④ After the end surface 12 is coated with glue, it is bonded to the printed board layer 2. The bottom surface of the printed board layer 2 is bonded to the end surface 12. During the bonding process, the bottom surface of the printed board layer 2 presses down on the cushion layer 5. Because the cushion layer 5 has a honeycomb structure inside, after being squeezed by the printed board layer 2, some of the gas inside the cushion layer 5 is squeezed out from the upper end of the end surface 12, and the cushion layer 5 completely fills the groove 211. After the printed board layer 2 is bonded to the substrate 1, it needs to be leveled. Because the cushion layer 5 fills the groove 211, the cushion layer 5 provides support for the protrusion 21, allowing the protrusion 21 to withstand a certain amount of pressure and reducing the frequency of its deformation.

[0040] ⑤ If Figure 3 、 Figure 4 As shown, the two sides of the groove body 11 are inserted with the pad 4, and the end faces on both sides of the pad 4 are respectively against the end face 4 321 and the wall 112. The pad 4 moves the plugboard 3 toward the end face 3 13 side until the base plate 32 is flush with the end face 3 13 during the insertion process. In this process, the spacing between the raised portion 31 and the printing plate layer 2 increases, so that the cushion layer 5 that was originally squeezed expands and recovers the free state (that is, the cushion layer 5 is in a state not subjected to pressure). Before the glue is completely solidified, in order to prevent the glue from locally gathering and causing the printing plate layer 2 to solidify after local protrusion, it is necessary to press the printing plate layer 2 so that the glue is evenly distributed and the printing plate layer 2 is better bonded to the substrate 1. When pressing the printing plate layer 2, because the internal air pressure of the cushion layer 5 is reduced after expansion, the two sides of the raised portion 31 produce a pressure difference, so that the printing plate layer 2 and the substrate 1 are more tightly combined to reduce the possibility that the printing plate layer 2 and the substrate 1 are easily moved relative to each other. When excess glue cannot be squeezed out, it is pressed into the groove 211, thereby making the entire printed board layer 2 smoother after molding. At the same time, because the cross-section of the protrusion 21 is curved, the ends of the curved shape are prone to debonding from the end surface 12. The pressure difference between the two sides of the protrusion 31 causes the protrusion 31 to shrink toward its curved shape, thereby reducing the occurrence of debonding between the ends of the curved shape and the end surface 12.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
