Description

Technical Field

[0001] The utility model relates to the technical field of plate processing equipment, in particular to an edge sealing device for plate production with a mildew-proof nano coating. Background Art

[0002] A board consists of three parts: base material, facing and edge banding.

[0003] A good edge banding has a smooth junction with the finish, no offset residue, and a good overall appearance after installation.

[0004] If the environmental protection level of the board is relatively high, the main function of edge sealing is to prevent moisture. Now the mainstream on the market is particle board. If the edge sealing is not done well, the board will easily peel and bulge, or even bend and other irreversible deformations in a humid environment for a long time.

[0005] Three edge banding processes: EVA edge banding, PUR edge banding and laser edge banding;

[0006] EVA stands for ethylene-vinyl acetate copolymer, a type of hot-melt adhesive. EVA edge banding involves applying high-temperature, liquefied EVA to the sides of the sheet. A pressure roller then presses the edge banding against the sheet. Once the EVA cools and solidifies, a strong bond forms between the two. This entire process is a physical reaction.

[0007] PUR stands for polyurethane reactive hot melt adhesive, a type of hot melt adhesive. The edge banding process is similar to EVA, where the sheet material is coated with high-temperature liquefied PUR material and then bonded with edge banding strips. However, PUR is a reactive adhesive. The isocyanate (-NCO) groups in it undergo a chemical cross-linking reaction with water molecules in the environment or the substrate, forming a moisture-curing process. This entire process is chemical and irreversible.

[0008] Laser edge banding is different from the above two hot melt adhesive edge banding technologies. No additional glue is required. The edge banding strip has its own coating. The functional layer of the edge banding strip is quickly melted by high-energy laser, and then the edge band is pressed tightly on the workpiece through the pressure wheel mechanism.

[0009] The curing process can be either a physical or chemical reaction, depending on the coating material.

[0010] However, in actual use, the existing technology still has the problem that if the edge sealing is not done well, the board will easily peel and bulge, or even bend and other irreversible deformations will occur in a humid environment for a long time. Utility Model Content

[0011] Therefore, in response to the above-mentioned problems, the present invention proposes an edge sealing device for board production with an anti-mildew nano-coating, which solves the technical problem that in the actual use of the existing technology, if the edge sealing is not done well, the board will easily peel and bulge, or even bend and other irreversible deformations in a humid environment for a long time.

[0012] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an edge banding device for producing plates with a mildew-proof nano-coating, the structure of which includes an edge banding device body, a supporting roller, a side positioning roller, a lower pressure plate, a lower pressure support spring, a lower pressure plate positioning wheel, an edge banding strip bonding wheel, an edge banding strip input positioning wheel, a nano-coating spray gun, a spray gun control valve, a nano-material tank, and a spray limit cover. The edge banding device body is provided with a supporting roller and a side positioning roller for supporting the plate, a lower pressure plate is provided between the two side positioning rollers, and the lower pressure plate A lower pressure plate positioning wheel is provided at the front end, and the lower pressure plate is connected to the edge banding device body through a lower pressure support spring, and an edge banding strip bonding wheel for bonding the edge banding strip to the plate is provided on the front side of the lower pressure plate positioning wheel, and an edge banding strip input positioning wheel is provided on the left side of the edge banding strip bonding wheel, and a nano-coating spray gun is provided at the front end of the edge banding strip bonding wheel, and a spray gun control valve is provided on the nano-coating spray gun, and the front part of the nano-coating spray gun is connected to the nano-material tank through a pipeline, and a spray limit cover is provided on the periphery of the nozzle of the nano-coating spray gun.

[0013] Furthermore, a glue coating roller for coating the edge banding strip with glue is provided at the front end of the edge banding strip input positioning wheel.

[0014] Furthermore, the front end of the nano-coating spray gun is connected to the output pipe of the air pump.

[0015] Furthermore, the upper and lower edges of the spray limiting cover correspond to the upper and lower surfaces of the plate.

[0016] Furthermore, the spray limit cover is made of metal.

[0017] Furthermore, baffles are also provided on the left and right sides of the spraying limit cover, and the left and right widths of the spraying limit cover are 3-5 cm.

[0018] Furthermore, an exhaust hood for discharging excess atomized paint is provided next to the spray limit hood.

[0019] By adopting the above-mentioned technical solution, the beneficial effect of the utility model is as follows: the edge sealing device for plate production with anti-mildew nano-coating improves the existing technology. In actual use, if the edge sealing is not done well, the plate will easily peel and bulge, or even bend or other irreversible deformations in a humid environment for a long time. By arranging an anti-mildew nano-coating on the inner side of the edge banding strip, even if the edge banding strip of the plate warps or breaks during long-term use, the main body of the plate will not be affected by moisture and mold, thereby ensuring the maximum service life of the plate and avoiding bending and deformation of the plate.
