Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane manufacturing technology, specifically to an adhesive coating device for the production of polymer self-adhesive film membranes. Background Art

[0002] In the production of polymer self-adhesive film rolls, a glue coating machine is required. The main function of the glue coating machine is to apply glue to the pre-impregnated and dried roll material (such as paper rolls) to increase the glue content. The roll material (e.g., paper rolls) enters the glue coating machine after impregnation and drying. Traditional glue coating equipment typically consists of a coating unit, a glue tank, and a scraper. Figure 1 As shown, the gluing unit includes a gluing roller (A) and a pressure roller (B). The pressure roller is positioned above the gluing roller, and the two surfaces rotate in contact. The roll / paper roll to be glued (C) passes through the gap between them. Pressure-sensitive adhesive (E) is placed in the glue tank (D). A scraper (F) is positioned on one side of the glue tank, and then the scraper contacts the surface of the gluing roller. During the rotation of the gluing roller, after the gluing roller passes through the adhesive, some excess adhesive remains. The excess adhesive is blocked by the scraper. A common design feature is that the surface of the gluing roller has a horizontal adhesive storage groove (a) extending along its length. Figure 2 As shown. Traditional equipment produces polymer self-adhesive films, such as... Figure 3 As shown, horizontally spaced adhesives (G) are formed on the surface of the roll / paper roll (C), with the length direction of the adhesives perpendicular to the length direction of the roll / paper roll. However, a drawback of this paper bag is that the gaps between the adhesives are thinner than the overall thickness, which refers to the thickness of the adhesives and the roll / paper roll. Assuming that the force is perpendicular to the length direction of the paper roll between two adhesives, as shown at point b in the figure, it is easily broken and cannot withstand the force. The typical spacing between the adhesives is 0.3mm to 0.4mm. Therefore, as a technical improvement, this invention is hereby applied for. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a coating device for producing polymer self-adhesive film rolls, which can improve the above deficiencies.

[0004] This utility model relates to a coating device for producing polymer self-adhesive film rolls, including an input conveyor roller and an output conveyor roller. An upper coating unit and a lower coating unit are arranged between the input and output conveyor rollers. The corneal tape / paper strip bag to be coated passes through the input conveyor roller, the output conveyor roller, and the coating unit and the lower coating unit, and moves through them. A lifting adjustment device is connected to the input conveyor roller to change the tension of the tape. The upper coating unit includes a first extrusion roller, a first coating roller, and a glue-spraying pipe. A melting tank is set at the roller gap between the first extrusion roller and the first coating roller. The glue-spraying pipe transports the glue to the melting tank. The lower coating unit includes a second coating roller and a glue storage tray. The surface of the second coating roller is close to that of the first coating roller. A glue storage tray containing adhesive liquid is provided at the lower part of the second coating roller. Glue storage grooves are engraved on the smooth circumferential surface of the second coating roller, evenly distributed at an angle to the left or right along the axis centerline.

[0005] Furthermore, the top surface of the glue storage tray is provided with a glue storage trough, the adhesive liquid is placed inside the glue storage tray, and the glue storage trough is provided with return grooves around its perimeter.

[0006] Furthermore, the glue storage tray is rectangular, and arc-shaped sliding plates are provided on both sides of its top surface along the length direction. The arc-shaped sliding plates are fixed to the outside of the return groove.

[0007] Furthermore, an installation plate is provided on the side of the glue storage tray, an adjustment rod is provided on the installation plate, and a glue scraping device is provided on the adjustment rod.

[0008] Furthermore, the adhesive scraping device is a blade, which is close to the surface of the second adhesive roller.

[0009] Furthermore, the blade tip has a chamfer, and an arc-shaped curved edge is provided at the connection point with the chamfer.

[0010] Furthermore, the scraping device includes a scraper roller, blades evenly distributed on the scraper roller, and a telescopic device, wherein the scraper roller is connected to the telescopic device.

[0011] Furthermore, the lifting adjustment includes a worm gear adjustment device, a lead screw motor adjustment device, or a cylinder adjustment device.

[0013] Furthermore, the glue storage tray has multiple inclined partitions in the glue storage groove, and the multiple partitions are arranged to cross each other to form a grid structure.

[0014] This invention features a simple yet ingenious design that can be processed into a double-sided adhesive tape. The increased thickness enhances the tape's load-bearing capacity. The key lies in the coating roller. On the second coating roller, smooth circular surfaces are engraved with evenly distributed adhesive storage grooves arranged at an angle to the left or right along the axis centerline. Using this equipment, a polymer self-adhesive film product is produced, in which the adhesive on one side of the surface is distributed in an inclined manner, with the length direction of the adhesive inclined to the length direction of the self-adhesive film product, rather than perpendicular to it. This structure provides greater stress resistance when the applied force is perpendicular to the product direction. Attached Figure Description

[0035] Example 2, as Figure 8 , 4As shown in Figure 5, this utility model relates to a coating device for producing polymer self-adhesive film rolls, including an input conveyor roller 1 and an output conveyor roller 2. An upper coating unit and a lower coating unit are arranged between the input and output conveyor rollers, both mounted on a frame. The polymer self-adhesive film roll / paper strip 101 passes through the input conveyor roller, the output conveyor roller, and between the coating unit and the lower coating unit, moving via the two conveyor rollers and the upper and lower coating units. A lifting adjustment device 13 is connected to the input conveyor roller to change the tension of the paper strip. The upper coating unit includes a first extrusion roller 3, a first coating roller 4, and a glue-spraying pipe 14. A melting tank 141 is provided at the roller gap between the first extrusion roller and the first coating roller. The adhesive tube delivers the adhesive to the melting tank.

The smooth circumferential surface of the second coating roller is engraved with glue storage grooves 53 evenly distributed along the axis centerline at an angle to the left or right. The angle can be selected within the range of 4 to 10° as required by the product. In this embodiment, the angle C is 8° or 7°. Smooth support surfaces 52 are provided at both ends of the second coating roller. The distance between adjacent glue storage grooves is less than 0.3 mm, and is generally 0.2 mm.

[0036] like Figure 5 As shown, as a technical improvement, a glue storage tank 7 is provided on the top surface of the glue storage tray, the adhesive liquid is placed in the glue storage tray, and a return groove 71 is provided around the glue storage tank. The return groove is used for excess adhesive to drip here and flow into the glue storage tank.

[0037] To facilitate the collection of adhesive, as a technical improvement, the adhesive storage tray is rectangular, with arc-shaped sliding plates 8 on both sides of its top surface along the length direction. The arc-shaped sliding plates are fixed to the outside of the return groove by bolts. The arc-shaped sliding plates are turned outward, and their exposed width is greater than the side wall of the adhesive storage tray.

[0041] As a technological improvement, the lifting adjustment includes a worm gear adjustment device, a lead screw motor adjustment device, or a cylinder adjustment device.

[0042] Both embodiments of this solution design products in the form of double-sided adhesive tape, specifically, such as Figure 10 As shown, the formed self-adhesive film product includes a paper roll, denoted as film strip g, and an inclined adhesive h on one side of the film strip. Under the same force applied at the same position as in the prior art, at point b in the figure, the design of this product ensures that the force does not pass through the adhesive. In other words, the inclined adhesive design increases strength compared to the vertical design. Furthermore, this design uses double-sided adhesive, which further increases strength. In addition, since the spacing between adjacent adhesive storage grooves in this design is less than 0.3 mm, typically 0.2 mm, this spacing is smaller than the adhesive spacing of polymer self-adhesive films produced by equipment in the prior art, which also increases the density of the inclined adhesive.
