Detailed Description
In order to more clearly illustrate the embodiments of the present invention, the following description will explain embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.
The first embodiment is as follows:
as shown in fig. 1, the glue applying device for a protective film of the present embodiment includes: the device comprises a support frame 1, a guide rail 2, a sliding block 3, a fixing plate 4, a sizing roller 5, a middle roller 6, a guide roller 7 and a rubber disc 8.
The two cylindrical guide rails 2 are respectively arranged on the support frames 1 on the two sides, and the two sliding blocks 3 are provided with circular through holes with the same diameter as the cylindrical guide rails and are used for adjustably arranging the sliding blocks on the two guide rails 2. The slide block adjusting mechanism can adopt various different forms, for example, a spring bolt connected with an adjusting button is arranged on the slide block, a plurality of jacks are arranged on the guide rail, when the position of the slide block needs to be adjusted, the adjusting button is pressed down to enable the spring bolt to leave the jacks, and when the slide block reaches a proper position, the adjusting button is loosened to enable the spring bolt to enter the jacks at the position.
The two fixing plates 4 are respectively and fixedly arranged on the two sliding blocks 3. As shown in fig. 2, each fixing plate is formed by vertically welding two flat steels, the flat steel at the side is provided with a mounting hole 12 for mounting a guide roller, and the flat steel at the bottom is used for welding the fixing plate to a slide block. Two guide rollers 7 are arranged between the two fixing plates 4 and arranged in parallel
As shown in fig. 2, the gluing device for protective film of the present invention further comprises a long hole member 9, a clamping bolt 10 and a bearing 11. The two long hole pieces 9 are welded at the bottoms of the two fixing plates 4 respectively, the two bearings 11 are clamped in the long holes of the two long hole pieces 9 respectively, and the two ends of the middle roller 6 are mounted on the two bearings respectively and arranged in parallel with the guide roller. The side of the long hole piece is provided with a screw hole for arranging a clamping bolt 10, and when the clamping bolt is loosened, the bearing 11 can freely adjust the height position in the long hole; when the clamping bolt is screwed down, the tail end of the clamping bolt props against the bearing, so that the bearing is locked by the clamping bolt and the wall of the long hole, the height position of the bearing in the long hole is limited, and the height position of the middle roller is adjusted. The height position of the middle roller is designed to be adjustable, so that the protective film which needs to be coated and glued can be replaced conveniently. As shown in fig. 3, after coating of one protective film is completed, the clamp bolt is loosened, the guide roller is placed on the upper table to increase the distance between the middle roller and the guide roller, then a new protective film without glue is replaced, the guide roller is placed downwards to enable the middle roller and the guide roller to be tightly attached to two sides of the protective film, and finally the clamp bolt is tightened. Another purpose of the clamping bolts is to prevent possible shaking of the intermediate roller rotating rapidly during gluing.
Two guide rollers 7 are the not co-altitude and arrange, arrange respectively in the top at middle roller 6 both sides, and middle roller and two guide roller dislocation coordination, after the protection film installation is gone into the position, lift and fixed middle roller, make the surface of guide roller and middle roller laminate in the both sides of protection film respectively to make the protection film keep certain tensile force when the coating rubberizing, effectively reduced product fold and the inhomogeneous risk of coating.
The gluing roller 5 and the middle roller 6 are arranged in parallel, and two ends of the gluing roller are rotatably arranged on the support frames 1 at two sides. Rubber layers are attached to the surfaces of the upper roller body and the middle roller body, so that the glue can be better adsorbed. The rubber plate 8 is fixed on the support frame 1 and filled with glue, and the surface of the rubber plate is in clearance fit with the surface of the upper rubber roller 5.
At the start of coating, the slide 3 is adjusted downwards, as shown in figure 4, so that the intermediate roller 6 is in tangential contact with the gumming roller 5. The guide rollers 7 rotate in the opposite direction to the intermediate roller 6, and move the protective film. Glue is dipped on the surface of the gluing roller, the glue is transferred to the middle roller along with the rotation of the gluing roller and the middle roller, and the middle roller coats the glue on the surface of the protective film.
As shown in fig. 5, when production is not needed, the slide block 8 moves up to the sizing device to be in a stop state, the sizing roller 1 stops moving, and the sizing roller 1 and the intermediate roller 2 are cleaned.
