Abstract
Description
Technical Field
[0001] This application relates to the field of coating roller technology, and in particular to a coating roller for making spacer tape. Background Technology
[0002] Currently, a glue-applying roller is a type of roller used for applying adhesives, commonly found in industries such as printing, packaging, and textiles. Its main function is to evenly coat the adhesive onto the material surface, ensuring a good bonding effect.
[0003] In existing technology, spacer tapes are divided into adhesive and non-adhesive areas. The adhesive area is coated with adhesive, making it sticky and able to adhere to surfaces for fixing the tape or attaching it to components requiring separation. The non-adhesive area contains no adhesive and is used to isolate or protect surfaces, preventing adhesion or unnecessary sticky contact. When manufacturing spacer tapes, specialized adhesive rollers are required to process the substrate.
[0004] Regarding the aforementioned technologies, the inventors believe that the special rubber rollers used to make spacer tapes are expensive, the process is complex, and the maintenance costs after the coating rollers are damaged are high, which affects the processing efficiency of spacer tapes. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a coating roller for making spacer tape, which solves the technical problems that the special coating roller used for making spacer tape is expensive, the process is complicated, the maintenance cost after the coating roller is damaged is high, and the processing efficiency of spacer tape is affected.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A coating roller for producing spacer tape includes a coating roller body with glue outlet holes spaced apart on the roller body. The roller body is characterized by having a barrier film attached to it; a coating port spaced apart on the barrier film; one side of the barrier film containing the coating port forming a glued area, and the other side forming a non-glue area; and a connecting assembly connecting the barrier film to the roller body.
[0008] Furthermore, a sealing gasket is provided on the side of the barrier film near the coating roller body, and the sealing gasket is pressed between the barrier film and the coating roller body.
[0009] Furthermore, a sealing protrusion is formed on the sealing gasket, and the sealing protrusion protrudes inward toward the adhesive applicator.
[0010] Furthermore, a buffer layer is provided between the sealing gasket and the barrier membrane, and the thickness of the buffer layer is 0.5mm-5mm.
[0011] Furthermore, the coating roller body has an installation groove, the two ends of the barrier film are embedded in the installation groove, and the connecting component includes a pressure strip, which is snapped into the installation groove.
[0012] Furthermore, a guide slope is formed on the body of the coating roller, and the guide slope is inclined toward the inner side close to the mounting groove.
[0013] Furthermore, limit rings are provided at both ends of the coating roller body, and the limit rings abut against the barrier film.
[0014] In summary, this application includes at least one of the following beneficial technical effects of the coating roller for producing spacer tape:
[0015] The barrier film is cut to form a glue application port according to the design requirements. The barrier film is located on one side of the glue application port to form a glue-covered area, and the side of the barrier film adjacent to the glue application port forms a glue-free area. Then the barrier film is connected to the glue application roller body through a connecting component. When in use, the glue flows out from the glue outlet on the glue application roller body, eliminating the need for a special glue roller for making spacer tape. The process is simple, the maintenance cost after the glue application roller is damaged is low, and the processing efficiency of spacer tape is improved.
[0016] By setting up sealing gaskets and buffer layers, the coating effect of the coating roller on the substrate is improved;
[0017] The stability of the barrier film installed on the coating roller body is improved by setting the guide slope and pressure strip. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0026] This application discloses an adhesive roller for making spacer tape.
[0027] Reference Figure 1 A coating roller for producing spacer tape includes a coating roller body 1 with glue outlet holes 11 evenly spaced on the body. A barrier film 2 is attached to the coating roller body 1. The barrier film 2 has a coating port 21, which is a glued area 22, and the side of the barrier film 2 adjacent to a glue-free area 23 is a glue-free area 23. A connecting assembly 3 is provided on the coating roller body 1, and the barrier film 2 is connected to the coating roller body 1 via the connecting assembly 3.
[0028] Reference Figure 2 The glue outlet holes 11 are evenly spaced on the glue coating roller body 1. When in use, the glue flows out through the glue outlet holes 11 on the glue coating roller body 1. When the substrate passes under the glue coating roller body 1, the glue flowing out from the glue outlet holes 11 of the glue coating roller body 1 is coated on the substrate.
[0029] Several glue-applying nozzles 21 are evenly spaced on the barrier film 2. Since the barrier film 2 wraps around the glue-applying roller body 1, the glue outlets 11 on the glue-applying roller body 1 covered by the barrier film 2 cannot dispense glue. During use, glue will flow out through the glue-applying nozzles 21. Therefore, several glue-applying nozzles 21 of the barrier film 2 form glue-covered areas 22, and several glue-free areas 23 are formed between several adjacent glue-applying nozzles 21. As the glue-applying roller body 1 rotates, the substrate passes through the underside of the glue-applying roller body 1, thereby forming a spacer tape.
[0030] Reference Figure 3Furthermore, a sealing gasket 24 is provided between the coating roller body 1 and the barrier film 2. The sealing gasket 24 is adhered to the side of the barrier film 2 near the coating roller body 1. When the barrier film 2 is wrapped around the coating roller body 1, the sealing gasket 24 presses against the coating roller body 1. In addition, a sealing protrusion 241 is formed on the sealing gasket 24, which corresponds to the glue outlet 11. When the barrier film 2 is attached to the coating roller body 1, the sealing protrusion 241 protrudes into the corresponding glue outlet 11, thereby reducing excess glue entering between the coating roller body 1 and the barrier film 2.
[0031] Furthermore, a buffer layer 25, made of rubber, is provided between the barrier film 2 and the sealing gasket 24. When the coating roller body 1 is used to apply adhesive to the substrate, the coating roller body 1 contacts the substrate through the buffer layer 25, which improves the coating effect of the coating roller body 1 on the substrate surface. Further, the thickness of the buffer layer 25 is 0.5mm-5mm, preferably 2mm.
[0032] Furthermore, due to the provision of the buffer layer 25, after the barrier film 2 is adhered to the glue coating roller body 1, the buffer layer 25 and the sealing gasket 24 can further reduce the flow of excess glue from the glue coating port 21 at the area covered by the barrier film 2.
[0033] Because the spacing between the adhesive area 22 and the non-adhesive area 23 of different spacer tapes is different, and the barrier film 2 needs to be replaced periodically, in order to improve the convenience of barrier film 2 replacement, an installation groove 12 is provided on the coating roller body 1. The length direction of the installation groove 12 is parallel to the axial direction of the coating roller body 1. In use, both ends of the barrier film 2 are embedded into the installation groove 12 of the coating roller body 1. Furthermore, the connecting component 3 includes a pressure strip 31. After both ends of the barrier film 2 are embedded into the installation groove 12 of the coating roller body 1, the pressure strip 31 is pressed tightly into the installation groove 12 of the coating roller body 1.
[0034] Reference Figures 4-5 Furthermore, to facilitate the insertion of the pressure strip 31 into the mounting groove 12, a guide slope 13 is formed on the coating roller body 1. The guide slope 13 is located on both sides of the mounting groove 12 and is arranged opposite to each other, with the two guide slopes 13 inclined towards the inner side of the mounting groove 12. In use, the pressure strip 31 is inserted into the mounting groove 12 through the guide slope 13. A connecting bolt 32 is provided on the pressure strip 31, with one connecting bolt 32 at each end of the pressure strip 31. One end of the connecting bolt 32 passes through the pressure strip 31 and connects to the coating roller body 1.
[0035] Reference Figure 1Limiting rings 14 are provided at both ends of the glue coating roller body 1 along the axial direction. The limiting rings 14 are coaxially arranged with the glue coating roller body 1. Nuts 33 are provided on the glue coating roller body 1. The nuts 33 are threadedly connected to the glue coating roller body 1. One end of the nut 33 is pressed against the limiting ring 14. As the nut 33 rotates, the limiting ring 14 is pressed against both ends of the glue coating roller body 1, thereby reducing the amount of glue flowing out from both ends of the glue coating roller body 1 along the axial direction when the glue coating roller body 1 is applying glue.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
