Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an adhesive tape used for sealing upper and lower molds for making eyeglass lenses. Background Art

[0002] In the process of making eyeglasses, eyeglass molds are usually used. After the molds are filled with liquid eyeglass materials, the upper and lower molds are sealed with tape. After the tape is sealed, the eyeglasses are baked at high temperature to complete the production process and finally obtain the finished eyeglasses. However, during the process of using tape to seal the upper and lower molds of eyeglasses, the liquid eyeglass materials may seep through the tape to the edge or other areas of the eyeglasses, resulting in adverse effects of the produced eyeglasses.

[0003] For example, the Chinese patent CN207581722U discloses a tape for sealing the upper and lower molds of eyeglass lenses. The device includes a mesh layer, a lower soft rubber layer, a canvas layer, a wear-resistant layer, an upper soft rubber layer, an adhesive primer layer and other components. The tape can seal the upper and lower molds well, avoiding the occurrence of cracking of the upper and lower molds during high-temperature baking. However, when the tape is used to seal the upper and lower molds, the liquid material for making the eyeglass lens may penetrate through the tape to the edge of the eyeglass lens or other areas, thereby resulting in defective eyeglass lenses and reducing the production quality of the device.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0011] Furthermore, in order to effectively prevent the liquid material of the lens from leaking through the gap between the upper and lower molds of the lens to the edge of the lens or other areas, and avoid adverse effects of the manufactured lenses, the waterproof layer is sequentially arranged from top to bottom with an adhesive layer, a waterproof isolation layer and a waterproof coating.

[0012] Furthermore, in order to make the tape body have higher wear resistance and prevent the upper and lower molds of the eyeglass lens from being worn or damaged during the manufacturing process, the wear-resistant layer is made of polyurethane or acrylic material.

[0026] According to an embodiment of the utility model, an adhesive tape for sealing upper and lower molds for manufacturing eyeglass lenses is provided.

[0027] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 5 The tape for sealing the upper and lower molds of eyeglass lenses according to the embodiment of the utility model includes a tape body 1, and a mounting seat 2 is arranged inside the tape body 1; the tape body 1 is provided with an adhesive layer 3, a reinforcement layer 4, a high temperature resistant layer 5, a waterproof layer 6 and a wear-resistant layer 7 from the inside to the outside.

[0028] With the aid of the above technical solution of the utility model, by setting the waterproof layer 6, the upper and lower molds can be tightly sealed during the production of the eyeglasses, effectively preventing the liquid material of the eyeglasses from leaking through the gap between the upper and lower molds of the eyeglasses to the edge or other areas of the eyeglasses, avoiding the adverse effects of the produced eyeglasses, thereby improving the quality and accuracy of the eyeglasses. By setting the high temperature resistant layer 5, the stability and performance can be maintained in a high temperature environment, preventing the deformation, melting or loss of adhesion of the tape due to high temperature during the production process. At the same time, the upper and lower molds of the eyeglasses are protected to prevent the upper and lower molds of the eyeglasses from being damaged or deformed under high temperature conditions, which helps to maintain the accuracy of the mold and extend the life of the mold. By setting the wear-resistant layer 7 and the reinforcing layer 4, the durability of the tape body 1 can be increased, with higher strength and tensile strength, and the upper and lower molds of the eyeglasses can be protected to prevent the upper and lower molds of the eyeglasses from being worn or damaged during the production process, thereby improving the quality and efficiency of the sealed production of eyeglasses.

[0029] In one embodiment, for the adhesive layer 3, a rubber layer 8 is provided between the adhesive layer 3 and the reinforcing layer 4, so as to increase the toughness and tensile strength of the tape body 1 and help prevent the mold from moving or deforming during the manufacturing process.

[0030] In one embodiment, for the above-mentioned reinforcing layer 4, the reinforcing layer 4 includes an inner skeleton layer 401, a polyester film layer 402 and an outer skeleton layer 403 arranged in sequence from top to bottom, so that the tape body 1 has higher strength and provides additional strength and support for the upper and lower molds of the lens.

[0031] In addition, it should be noted that the material of the inner skeleton layer 401 can be glass fiber cloth, which is a high temperature resistant and wear-resistant material used to enhance the tensile strength and durability of the tape; the material of the outer skeleton layer 403 can be polymer fiber, such as polyamide fiber nylon or polyethylene fiber, used to enhance the strength and stability of the tape.

[0036] In one embodiment, the wear-resistant layer 7 is made of polyurethane or acrylic material, so that the tape body 1 has high wear resistance and prevents the upper and lower molds of the eyeglass lens from being worn or damaged during the manufacturing process.

[0037] In addition, it should be noted that polyurethane or acrylic has high wear resistance, which can protect the tape from being worn during the production process.

[0038] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0039] In actual application, the liquid material for the glasses is filled into the upper and lower molds of the glasses, and the upper and lower molds of the glasses are wrapped and sealed with the tape body 1, wherein the waterproof layer 6 can effectively prevent the penetration and leakage of the liquid material for the glasses. After the sealing is completed, the lens mold and the tape body 1 are baked at high temperature, wherein the wear-resistant layer 7, the high temperature resistant layer 5 and the reinforcing layer 4 can protect the upper and lower lens molds to ensure that the production process in a high temperature environment proceeds smoothly. After the high-temperature baking is completed, the lens mold is taken out, the sealed tape body 1 is untied, and the lens production is completed.

By setting the high temperature resistant layer 5, the stability and performance can be maintained in a high temperature environment, preventing the deformation, melting or loss of adhesion of the tape due to high temperature during the production process. At the same time, the upper and lower molds of the eyeglasses are protected to prevent the upper and lower molds of the eyeglasses from being damaged or deformed under high temperature conditions, which helps to maintain the accuracy of the mold and extend the life of the mold.
