Technical Field

The invention belongs to the technical field of furniture boards, and particularly relates to a zero-clearance sealing decoration technology for peripheral end faces of the furniture boards.

Background

Chinese patent 200920264993.8 "Panel bordure bender" discloses a panel bordure bender, including convex module, die block, offer the trough as die on the said concave module, the cross section of the bottom of the said trough is a circular arc; and the convex module is provided with a bulge matched with the groove in shape and used as a convex die. According to the plate edge covering bending die, the convex module and the concave module are arranged, the strip-shaped groove with the arc-shaped cross section is formed in the concave module, and the convex die with the corresponding shape is arranged on the convex module, so that when the edge covering plate is placed between the concave and convex modules, the bending machine is started, the edge covering plate can be processed into the edge covering strip with the required shape, the use is convenient, and the small-batch production can be realized at lower cost.

At present, the decoration surface layer wrapped on the surface of furniture or other plates is mainly of two types, the first type is soft gummed paper or film, etc., the paper is easy to bend and deform, and easy to wrap edges of the adhered plates, but the gummed paper or film is not durable and easy to damage, and can not be well adhered to the plates, especially the rough end surfaces of the newspaper board for a long time, after the gummed paper or film is used for a period of time due to the elastic action, the gummed paper or film is degummed from the rough end surfaces of the newspaper board, the gummed paper or film on the end surfaces of the newspaper board is easy to damage, loses the decoration effect and becomes the rotten furniture. The Chinese patent 'plate edge-covering bending die' is a die for the edge-covering end face of a plate with gummed paper or a film, and after the edge-covering end face of the plate with the die is used, the problem that the gummed paper or the film is weak due to thinness is still not solved.

The second is to use thick plastic decorative surface material, in order to solve the problem that the decorative layer on the surface of the plate is durable, the thick plastic decorative surface material of PVC or other materials with the thickness of 1.5-2.5 is widely used at present, but all the thick plastic decorative surface materials have the problems of difficult bending and accurate modeling, unattractive edge-covered corner and poor long-term adhesion with the rough end surface of the newspaper board. The existing method for solving the two problems is to use a PVC thick decorative strip which is as wide as the end face of the plate to be stuck on the end face of the plate in a long way without corner edge wrapping. The PVC thick decorative strip adhered to the end face of the board is not durable, the strip adhered to the end face cannot be completely sealed for a long time, and after the periphery of the strip enters air, the end face of the board and the adhesive absorb water, mildew and deform, so that the thick decorative strip gradually separates from the end face of the board, the attractive decorative effect of the thick decorative strip is lost, and the thick decorative strip becomes old rotten furniture.

Therefore, the technical scheme that the end face of the plate is wrapped by the glue-coated paper or the thin film is not durable, but the end face of the plate is pasted and sealed by the PVC thick decorative strip and cannot be completely sealed around for a long time and is not durable, the thick plastic decorative surface material pasted on the surface of the plate is directly bent and wrapped, the bending modeling is inaccurate and not attractive, and the thick plastic decorative surface material is not firmly adhered to the end face of the plate is expected in the technical aspect, the thick plastic decorative surface material on the surface of the plate can be directly bent and wrapped without gaps, the bending modeling is accurate and attractive, and the thick plastic decorative surface material is firmly adhered to the end face.

Disclosure of Invention

The invention aims to provide an end face gapless edge-covered plate which is easy to bend and accurately shape a thick plastic decorative surface material and can be firmly adhered to the end face of the plate when the end face of the plate is directly bent and gapless edge-covered by using a process operation.

The conception of the invention is as follows: two or more geometric bar-shaped members are adhered to the thick plastic decorative surface material used for the local position of the edge of the substrate, the bending of the members is used for forcing the thick plastic decorative surface material to be bent according to the specified shape and angle of the member edge, the members are solid wood or multilayer plates, and the members can be well adhered to the thick plastic decorative surface and the substrate. The bar-shaped members with the geometric shapes of the materials are used for carrying the bending and pasting of the thick plastic decorative surface material, so that the problems that the corner of the thick plastic decorative surface material is irregular and can rebound and be separated from the base plate by degumming due to the direct bending and direct pasting of the thick plastic decorative surface material are solved, and the problems that the direct bending and modeling of the thick plastic decorative surface material are not good and attractive and the adhesion with the end surface of the newspaper board is not firm are solved.

The structure of the invention is as follows:

the panel terminal surface carries out the terminal surface zero-clearance panel that turn bordures with geometry and decorative layer, including base plate 1 and paste at 1 positive decorative layer 2 of base plate, at the terminal surface 3 of the base plate 1 that needs bordure, still include that decorative layer 2 extends base plate 1 and is used for borduring of borduring to use decorative plane materiel 4, its characterized in that: a strip-shaped combined component is arranged on the end surface 3 of the substrate 1 and comprises two or more auxiliary turning component strips 5;

two or more auxiliary turning member strips 5 for turning the decorative surface material 4 for auxiliary edge covering are arranged on the surface of the decorative surface material 4 for edge covering, which is adhered with the surface of the substrate 1, the auxiliary turning member strips 5 are parallel to each other, and the auxiliary turning member strips 5 are parallel to the end surface 3 of the substrate 1;

the end surface 3 of the substrate 1 is adhered with each auxiliary turning component strip 5, and the contact between the auxiliary turning component strips 5 is mutually adhered; the same edge covering decorative surface material 4 is bonded outside each auxiliary turning member strip 5, and the edge covering decorative surface materials 4 are different parts of the same material of the decorative layer 2;

at least one auxiliary folding member strip 5 has one surface parallel to or in the same plane with the back surface of the base plate 1, and the surface of the auxiliary folding member strip 5 is adhered with a decorative surface material 4 for edge covering.

In terms of manufacturing process, two or more auxiliary turning member strips 5 of strip-shaped combination members are arranged on the edge-covering decorative surface material 4 extending from the front edge of the base plate 1, and the two or more auxiliary turning member strips 5 are firstly arranged on the edge-covering decorative surface material 4 extending from the front edge of the base plate 1 in a separated parallel and side-by-side mode. The auxiliary turning member strips 5 can be made of wood or plastic with strength, the hardness and the strength of the auxiliary turning member strips 5 are higher than those of the decorative surface material 4 for edge covering, and the auxiliary turning member strips 5 are made of materials which can be firmly adhered to the decorative surface material 4 for edge covering and the end face 3 of the base plate 1. The same layer of decorative covering material 4 is wrapped outside between the two auxiliary turning member strips 5 and between the auxiliary turning member strips 5 and the edge of the front surface of the base plate 1.

The hardness strength of the complex of the auxiliary folding member strips 5 to which the edge covering decorative surface material 4 is attached is higher than that of one layer of the edge covering decorative surface material 4, so that when two or more of the complex of the auxiliary folding member strips 5 to which the edge covering decorative surface material 4 is attached are folded from the front side to the back side of the substrate 1, the edge covering decorative surface material 4 can be folded only in order and accurately according to the edge lines of the auxiliary folding member strips 5. Therefore, after the auxiliary turning member strip 5 is adhered to the edge covering decorative surface material 4, the auxiliary turning member strip 5 has the characteristic of higher hardness and strength than the edge covering decorative surface material 4, the three corners of the edge covering decorative surface material 4 adhered together are forced to be in a seamless edge covering structure by the high-hardness corners of the auxiliary turning member strip 5, and the three corners are bent from the front surface to the back surface 12 of the substrate 1 to form ends orderly and accurately, so that the aim of completely performing seamless edge covering on the end surface 3 of the substrate 1 is fulfilled.

Two methods are adopted for arranging two or more auxiliary turning member strips 5 on the edge-covering decorative surface material 4 extending from the edge of the front surface of the substrate 1 in parallel, wherein the first method is to use a mould to fix the position on the edge-covering decorative surface material 4 and then paste the manufactured auxiliary turning member strips 5 at the set position; secondly, the area of the base plate 1 is increased, and two or more auxiliary turning member strips 5 are cut on the base plate with the increased area by a cutting machine, the method is easy to realize automation, and the position of each auxiliary turning member strip 5 on the decorative surface material 4 for edge covering is more accurate.

Before bending and edge covering, a line type local heating method such as infrared rays or laser can be used for locally heating a line to be bent of a decorative surface material 4 for edge covering, then glue is applied to each pasting part, and finally the decorative surface material 4 for edge covering and two or more auxiliary turning member strips 5 pasted on the decorative surface material are bent and pasted by a bent mechanical handle to prepare an end face gapless plate with a turning and edge covering decorative layer.

So that after bending, the non-adhered surface of the rectangular auxiliary turning member strip 5 is adhered to the edge-covering decorative surface material 4 with the same length and space distance, and one surface of the rectangular auxiliary turning member strip 5 can be just contacted with the end surface 3 of the substrate 1 so as to be adhered to the end surface 3. [2] The lower rectangular auxiliary turning member strip 5 is arranged, namely, the rectangular auxiliary turning member strip 5 with one surface in the same plane with the back surface of the substrate 1 is firstly adhered to the edge-covering decorative surface material 4 by one surface, the position of the rectangular auxiliary turning member strip 5 which is firstly adhered to the edge-covering decorative surface material 4 is separated from the rectangular auxiliary turning member strip 5 at the upper position by a space distance, and the length of the space distance is equal to the length of the surface of the rectangular auxiliary turning member strip 5 which is not adhered yet. After bending, the non-adhered surface of the rectangular auxiliary turning member strip 5 is adhered to the edge-covering decorative surface material 4 with the same length and space distance, so that one surface of the rectangular auxiliary turning member strip 5 can be adhered to the rectangular auxiliary turning member strip 5 at the upper position in a contact manner, the length of the rectangular auxiliary turning member strip 5 at the lower position is equal to or greater than the length of the rectangular auxiliary turning member strip 5 at the upper position, the rectangular auxiliary turning member strip 5 at the lower position can be in contact with the end surface 3 of the substrate 1, and the rectangular auxiliary turning member strip 5 at the lower position can be adhered to the end surface 3. Thus, the upper rectangular auxiliary turning member strip 5 and the lower rectangular auxiliary turning member strip 5 can be pasted in a contact manner, the two are pasted with the end surface 3 of the substrate 1 respectively to form a new end surface, the same edge covering decorative surface material 4 is pasted outside the two, and the new end surface is seamlessly edged by the same edge covering decorative surface material 4 to form an end surface gapless plate with two rectangular auxiliary turning member strips 5 matched with the decorative layer of the strip-shaped combined member for turning and edging.

In the second fig. 3 and 4, two triangular end face non-gap plates are matched to form the end face non-gap plates of the strip-shaped combined member.

One triangular auxiliary turning member strip 5 is close to the position angle of the end face 3, and no gap is left between the auxiliary turning member strip and the end face 3 or a small amount of gap is left according to the thickness turning requirement of the edge covering decorative surface material 4. Because the hardness strength of the auxiliary turning member strip 5 is greater than that of the edging decorative surface material 4, when the auxiliary turning member strip 5 adhered with the edging decorative surface material 4 is rotated, the softer edging decorative surface material 4 can only bend the outer corner of the three triangular auxiliary turning member strips 5 after the seamless edging is rotated and contacted with the adhered three triangular auxiliary turning member strips 5 according to the gap between the three triangular auxiliary turning member strips 5. When the auxiliary turning member strip 5 near the end face 3 is turned, the decorative surface material 4 for edge covering also seamlessly edges the corner formed by the auxiliary turning member strip 5 and the end face 3.

one side of the fourth triangular auxiliary turning member strip 5 is bonded with a decorative surface material 4 for edge covering, and the decorative surface material 4 for edge covering of the fourth triangular auxiliary turning member strip and the decorative surface material 4 for edge covering of the third triangular auxiliary turning member strip 5 form a corner structure; the fourth triangular edge-covering decorative surface material 4 and the decorative layer 2 on the front surface of the substrate 1 are made of the same material; the fourth decorative surface material 4 for triangle edge covering is in the same plane or parallel with the back of the base plate 1.

In terms of manufacturing process, as in the second operation, four triangular auxiliary folding member strips 5 are firstly pasted on the edge-covering decorative surface material 4 of the end surface 3 of the substrate 1 in parallel side by side, and no gap is left between two adjacent triangular auxiliary folding member strips 5 or a small amount of gap is left according to the thickness folding requirement of the edge-covering decorative surface material 4. One triangular auxiliary turning member strip 5 is close to the position angle of the end face 3, and no gap is left between the auxiliary turning member strip and the end face 3 or a small amount of gap is left according to the thickness turning requirement of the edge covering decorative surface material 4. Because the hardness strength of the auxiliary turning member strip 5 is greater than that of the decorative surface material 4 for edge covering, when the auxiliary turning member strip 5 adhered with the decorative surface material 4 for edge covering is rotated, the softer decorative surface material 4 for edge covering can only bend the outer corner of the seamless edge covering of the four triangular auxiliary turning member strips 5 after the rotation contact and adhesion according to the gaps between the four triangular auxiliary turning member strips 5. The end polygon assembly 11 formed by pasting the four triangular auxiliary turning member strips 5 is pasted with the end face 3 of the substrate 1 to form a polygon as a new end face of the substrate 1, three corners of the new end face are covered by the same edge covering with a decorative surface material 4 in a seamless edge covering manner, and the substrate 1 becomes an end face gapless plate for turning and edge covering of the decorative layer of the polygonal strip-shaped assembly member.

The invention has the advantages that: the patent uses a plurality of auxiliary turning component strips to help the decorative surface material with certain thickness, generally 0.5-2.5 mm thickness, to solve the problem that the end face of the plate can not be beautifully, directly and accurately bent into a seamless edge covering, and only can be additionally adhered to the end face of the plate by a decorative strip, so that the decorative strip adhered to the end face of the plate is lack of beauty, easy to fall off and not durable.

The durability of the end face of the plate is increased: compared with the prior art that paper or film is used as a thin decoration layer, the decoration surface material with the thickness of 0.5-2.5 mm is used as the surface thick decoration layer of the substrate and used as the end surface of the substrate, the decoration surface material is smooth and better and is more wear-resistant, the end surface corner is seamlessly wrapped by the thick decoration layer, the whole plate can be made into a totally-enclosed plate without air, and the plate is not affected with damp and is durable.

The attractiveness of the plate is improved: compared with the prior method of adhering the end face by using the edge strips, the seamless edge covering of the end face is more beautiful and has smoother corners.

The manufacturing process is simpler: the auxiliary turning member strip can be directly cut on the peripheral substrate part by a cutting machine at the periphery of the substrate adhered with the thick decorative surface material, the shape of the cut auxiliary turning member strip is accurate, the position is accurate, and the process of positioning and adhering the auxiliary turning member strip is not needed to be added, so that the processes of adhering the thick decorative surface material to the plate, cutting the auxiliary turning member strip and directly bending the auxiliary turning member strip with the thick decorative surface material to seamlessly edge the end surface of the plate are finished on a machine adhered with a surface layer at one time, and the seamless edge covering is simpler, the production quality is high, and the cost is low.

The existing process for positioning and adhering the edge banding on the end face of the plate needs to move the plate to another machine for adhering the edge banding to position and then adhere the edge banding after the surface decoration layer is adhered, the edge banding which is adhered to one end face needs to rotate one end face again to position and then adhere the edge banding on the machine, and the positioning of the end face is very time-consuming and requires accurate operation of a person, so that the old art is complex, the quality is not high, and the cost is high.
