Description

Technical Field

[0001] This utility model relates to the field of panel furniture processing, and in particular to an environmentally friendly, glue-free laser hot melt edge sealing strip. Background Technology

[0002] The main function of hot melt edge banding is to prevent the edges of boards from being damaged by moisture, collision or friction, and to extend their service life. Therefore, it is very common and widely used in the furniture industry. Chinese patent application number CN201920476767.X provides a laser hot melt sealing strip. The "n"-shaped groove of the anti-collision block of this solution will bend and spring back after a strong impact. Moreover, it uses laser hot melt sealing method to seal the edge, and the glue line is invisible after sealing, achieving a truly seamless edge sealing.

[0003] Existing hot melt edge sealing strip processes generally involve applying hot melt adhesive and then attaching the edge sealing strip, which has problems such as poor adhesion, release of harmful substances, and cumbersome processing. Although laser edge sealing technology has emerged, the edge sealing strip structure still needs to be improved to adapt to laser energy absorption and bonding efficiency. Therefore, we propose an environmentally friendly, glue-free laser hot melt edge sealing strip. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an environmentally friendly, glue-free laser hot-melt edge banding strip. By setting a laser absorption layer between the substrate body and the hot-melt layer of the edge banding strip, the laser absorption layer material can be carbon black polymer, metal oxide, or infrared absorber. Its function is to absorb laser energy and quickly convert it into heat, thereby enabling the edge banding strip to achieve efficient energy conversion, ensuring rapid activation of the hot-melt layer, shortening processing time, and eliminating the need for a glue machine during use. Only a laser device is required to complete the edge banding. It can be applied to furniture boards, cabinet boards, and various composite material edge banding, improving the practicality and environmental protection effect of the laser hot-melt edge banding strip.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An environmentally friendly, glue-free laser hot-melt sealing strip includes a sealing strip body and a hot-melt layer. A laser absorption layer is provided at the inner end of the sealing strip body, and a laser absorption layer is embedded in the interlayer between the sealing strip body and the hot-melt layer.

[0006] By adding a laser absorption layer, the practicality and environmental friendliness of this laser hot melt sealing strip are improved.

[0007] Furthermore, a hot-melt layer is adhesively bonded to the outer end of the seal body.

[0008] By adding a hot-melt layer, the hot-melt edge banding strip can be connected more conveniently.

[0009] Furthermore, the seal body includes a substrate body.

[0010] By setting a substrate body, which is made of PVC material, it is easy to process, has good flexibility, can adapt to complex shapes, has a moderate cost, and can be thermoformed, thus improving the performance of the edge banding strip.

[0011] Furthermore, the inner end of the seal body is provided with a connecting groove, and the connecting grooves are symmetrically distributed.

[0012] By incorporating a connecting groove, the connection performance of this hot-melt edge banding strip is further improved.

[0013] Furthermore, a decorative layer is provided on the outer surface of the seal body.

[0014] The use effect of this hot-melt edge banding strip is improved by adding a decorative layer.

[0015] Furthermore, a reinforcing layer is provided at the bottom end of the seal body, and the reinforcing layer is connected to the decorative layer.

[0016] By adding a reinforcing layer, the structural strength of the edge banding strip can be improved.

[0017] In summary, this utility model has the following beneficial effects: 1. By setting a laser absorption layer, a laser absorption layer is set between the substrate body and the hot melt layer of the sealing strip. The laser absorption layer material can be carbon black polymer, metal oxide or infrared absorber. Its function is to absorb laser energy and quickly convert it into heat, so that the edge sealing strip can achieve efficient energy conversion, ensure the rapid activation of the hot melt layer, shorten the processing time, and when in use, no glue machine is required, only a laser device is needed to complete the edge sealing. It can be applied to furniture board, cabinet board and various composite material edge sealing, which improves the practicality and environmental protection effect of the laser hot melt edge sealing strip. 2. By setting a connecting groove, the connecting groove can improve the bonding effect between the edge banding strip and the board and functional layer. After the hot melt layer is activated by laser, the connecting groove provides a "accommodating space" for the hot melt functional layer, allowing the molten material to flow into the groove to form an "interlocking" state, improving the bonding strength and further improving the connection effect of the hot melt edge banding strip. 3. By setting a decorative layer, which is located on the outer surface of the edge banding strip, the decorative layer can be made of PVC, PP, melamine film or wood grain paper, providing both aesthetic appeal and wear resistance, thus improving the performance of the hot melt edge banding strip.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0022] Reference Figure 1-5 As shown, an environmentally friendly, glue-free laser hot-melt sealing strip is provided in a preferred embodiment of the present invention. It includes a sealing strip body 1 and a hot-melt layer 2. A laser absorption layer 5 is provided at the inner end of the sealing strip body 1, and a laser absorption layer 5 is embedded in the interlayer between the sealing strip body 1 and the hot-melt layer 2.

[0023] Reference Figure 1-2 As shown, a hot melt layer 2 is glued to the outer end of the seal body 1.

[0024] By installing a laser absorption layer 5 between the substrate body 101 and the hot melt layer 2 of the sealing strip body 1, the laser absorption layer 5 can be made of carbon black polymer, metal oxide or infrared absorber. Its function is to absorb laser energy and quickly convert it into heat, so that the edge sealing strip can achieve efficient energy conversion, ensure the rapid activation of the hot melt layer 2, shorten the processing time, and complete the edge sealing without the need for a glue machine. It can be applied to furniture boards, cabinet boards and various composite material edge sealing. The function of the hot melt layer 2 is to contact the board. It is made of polyester hot melt material, which melts instantly under laser irradiation. The molten hot melt layer 2 contacts the edge surface of the board and is firmly bonded after cooling, making the connection of the hot melt edge sealing strip more convenient.

[0025] Reference Figure 1 , Figure 2 and Figure 4 As shown, the seal body 1 includes a substrate body 101.

[0026] Reference Figure 1-5As shown, the inner end of the seal body 1 is provided with a connecting groove 102, and the connecting grooves 102 are symmetrically distributed.

[0027] The substrate body 101 is made of PVC material, which is easy to process, has good flexibility, can adapt to complex shapes, has moderate cost, and can be hot-pressed. The connecting groove 102 can improve the bonding effect between the edge banding strip and the board and functional layer. After the hot melt layer 2 is activated by laser, the connecting groove 102 provides "accommodation space" for the hot melt functional layer, allowing the molten material to flow into the groove to form an "interlocking" state, thereby improving the bonding strength.

[0028] Reference Figure 3-5 As shown, a decorative layer 3 is provided on the outer surface of the seal body 1.

[0029] Reference Figure 4-5 As shown, a reinforcing layer 4 is provided at the bottom of the seal body 1, and the reinforcing layer 4 is connected to the decorative layer 3.

[0030] The decorative layer 3 is installed on the outer surface of the edge banding strip. It can be made of PVC, PP, melamine film or wood grain paper, which has both aesthetic appeal and wear resistance. The reinforcing layer 4 is located below the decorative layer 3 and is made of ABS or PET rigid plastic. It provides structural strength and support, thereby improving the structural strength of the edge banding strip.

[0031] Specific implementation process: When the edge banding strip is used, the decorative layer 3 is located on the outer surface of the edge banding strip. It can be made of PVC, PP, melamine film or wood grain paper, which has aesthetic and wear-resistant properties. The laser passes through the decorative layer 3 and the substrate body 101 and acts on the laser absorption layer 5. The laser absorption layer 5 converts light energy into heat energy, and the local temperature rises rapidly. The heat energy is conducted to the hot melt layer 2, which melts instantly. The molten hot melt layer 2 contacts the edge surface of the board and penetrates the microporous structure. The connecting groove 102 can improve the bonding effect between the edge banding strip and the board and functional layer. After the hot melt layer 2 is activated by the laser, the connecting groove 102 provides "accommodation space" for the hot melt functional layer, allowing the molten material to flow into the groove to form an "interlocking" state, improving the bonding strength. As it cools, the hot melt layer 2 solidifies, achieving a strong glue-free and environmentally friendly bond.
