Description

Technical Field

[0001] This utility model relates to the field of industrial laminating machine technology, and in particular to an adjustable solventless laminating machine gluing structure. Background Technology

[0002] Laminating machines bond two or more layers of materials together using adhesives. This gives existing materials new functions; for example, aluminum foil, film, paper, and non-woven fabrics are frequently used. They can also be laminated with films, sponges, and fabrics. Most common flexible packaging materials are laminated products. Each material has a different width, but most existing equipment uses either a glue roller that directly contacts the glue tank or a moving glue nozzle that reciprocates by spraying glue onto the roller. Both methods share the characteristic that the glue roller is always fully coated with glue, regardless of the material's width. This leads to continuous waste of glue on areas not in contact with the material, especially if the material is small. Improvements are urgently needed. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an adjustable solvent-free laminating machine gluing structure, including a mounting frame, a gluing roller, a coating roller, a mounting roller for material mounting, and a gluing device. The gluing roller, coating roller, and mounting roller are all mounted on the mounting frame and their circumferential surfaces are sequentially attached. The gluing device is mounted on the mounting frame and located on one side of the gluing roller. The gluing device includes a glue tank, an electric slide, a mounting platform, a transfer pipe, a spray nozzle, and a liquid pump. The glue tank is located below the gluing roller, the electric slide is mounted on the mounting frame and located above the glue tank, the mounting platform is fixedly mounted on the slide of the electric slide, and the liquid pump and spray nozzle are both fixedly mounted on the mounting platform. One end of the delivery pipe is connected to the glue spraying pipe, and the other end is located in the glue tank. The mounting frame is equipped with a stroke adjustment device, which includes a pair of mounting rods, a wiring mounting slot, a pair of movable mounting blocks, a pair of limit switch groups, and a pair of proximity switch groups. The pair of mounting rods and the wiring mounting slot are fixedly mounted on the mounting frame and located above the connection between the glue roller and the glue coating roller. The pair of movable mounting blocks are all mounted on the pair of mounting rods and slide in cooperation with the mounting rods. The glue spraying pipe is equipped with a mounting plate. The pair of limit switch groups and the pair of proximity switch groups are respectively mounted on the pair of movable mounting blocks and the mounting plate. The pair of limit switch groups and the pair of proximity switch groups are respectively connected to the electric slide and the liquid pump through a control circuit.

[0004] Using the above technical solution, a gluing device including a glue tank, electric slide, mounting platform, transfer pipe, glue spraying pipe with nozzle, and liquid pump can be used for mobile gluing. A stroke adjustment device including a pair of mounting rods, wiring mounting slots, a pair of movable mounting blocks, a pair of limit switch groups, and a pair of proximity switch groups is installed on the mounting frame above the connection between the gluing roller and the coating roller. The spacing of the pair of movable mounting blocks is adjusted according to the specific dimensions of the material to match the spacing and position of the material roller. After starting the gluing device, when the glue spraying pipe moves to the position of the pair of movable mounting blocks, the limit switch groups and proximity switch groups are activated sequentially. When the proximity switch group is triggered, the liquid pump starts, controlling the glue spraying tube to spray glue. When the limit switch group is triggered, it controls the electric slide to move a certain distance. When it moves to the position of another movable mounting block and triggers the limit switch, it controls the electric slide to move in the opposite direction. Then the electric slide can drive the glue spraying tube to move back and forth between the pair of movable mounting blocks and spray glue at the same time. To apply glue to materials of different sizes, only the pair of movable mounting blocks need to be adjusted in advance. After the glue application device is started, it can automatically adjust according to the position of the pair of movable mounting blocks and reciprocate between the pair of movable mounting blocks to avoid glue waste.

[0005] A further feature of this invention is that each of the pair of movable mounting blocks has a threaded hole, and each threaded hole contains a limiting screw.

[0006] By adopting the above technical solution, since each of the pair of movable mounting blocks has a threaded hole and a limiting screw is provided in each threaded hole, the pair of movable mounting blocks can be completely limited on the mounting rod by the limiting screw.

[0007] A further feature of this invention is that each of the pair of movable mounting blocks is provided with a pair of indicator plates for material size comparison.

[0008] By adopting the above technical solution, since each of the pair of movable mounting blocks is provided with a pair of indicator plates for material size comparison, the position of the movable mounting block on the mounting rod can be better determined according to the indicator plates, so as to align it with the two ends of the material on the mounting roller.

[0009] A further feature of this invention is that a notch is provided on the mounting frame below the upper rubber roller.

[0010] By adopting the above technical solution, since there is a notch on the mounting frame located below the glue roller, the glue that naturally drips from the glue roller can drip from the notch and fall back into the glue tank. Attached Figure Description

Detailed Implementation

[0015] like Figure 1-3 As shown, an adjustable solventless laminating machine gluing structure includes a mounting frame 1, a gluing roller 2, a coating roller 3, a mounting roller 4 for material mounting, and a gluing device 5. The gluing roller, coating roller, and mounting roller are all mounted on the mounting frame and their circumferential surfaces are sequentially attached. The gluing device is mounted on the mounting frame and located on one side of the gluing roller. The gluing device includes a glue tank 6, an electric slide 7, a mounting platform 8, a transmission pipe 9, a spray pipe 11 with a nozzle 10, and a liquid pump 12. The glue tank is located below the gluing roller, the electric slide is mounted on the mounting frame and located above the glue tank, the mounting platform is fixedly mounted on the slide of the electric slide, and the liquid pump and spray pipe are both fixedly mounted on the mounting platform. One end of the transmission pipe is connected to the spray pipe. The tube is connected at one end and the other end is located in the glue tank. The mounting frame is equipped with a stroke adjustment device 13. The stroke adjustment device includes a pair of mounting rods 14, a wiring mounting groove 15, a pair of movable mounting blocks 16, a pair of limit switch groups 17, and a pair of proximity switch groups 18. The pair of mounting rods and the wiring mounting groove are fixedly set on the mounting frame and located above the connection between the glue roller and the glue applicator roller. The pair of movable mounting blocks are set on the pair of mounting rods and slide in cooperation with the mounting rods. The glue spray tube is equipped with a mounting plate 19. The pair of limit switch groups and the pair of proximity switch groups are respectively set on the pair of movable mounting blocks and the mounting plate. The pair of limit switch groups and the pair of proximity switch groups are respectively connected to the electric slide table and the liquid pump through the control circuit.

[0016] A gluing device, including a glue tank, electric slide, mounting platform, transfer pipe, glue spraying pipe with nozzles, and liquid pump, allows for mobile gluing. A stroke adjustment device, consisting of a pair of mounting rods, wiring mounting slots, a pair of movable mounting blocks, a pair of limit switch groups, and a pair of proximity switch groups, is installed on the mounting frame above the connection between the gluing roller and the coating roller. The spacing of the pair of movable mounting blocks is adjusted according to the specific dimensions of the material to match the spacing and position of the material roller. After starting the gluing device, when the glue spraying pipe moves to the position of the pair of movable mounting blocks, the limit switch groups and proximity switch groups are triggered sequentially. After the switch group is triggered, the liquid pump starts and controls the glue spraying tube to spray glue. After the limit switch group is triggered, it controls the electric slide to move a certain distance. When it moves to the position of another movable mounting block and triggers the limit switch, it controls the electric slide to move in the opposite direction. Then the electric slide can drive the glue spraying tube to move back and forth between the pair of movable mounting blocks and spray glue at the same time. To apply glue to materials of different sizes, only the pair of movable mounting blocks need to be adjusted in advance. After the glue application device is started, the glue application device can automatically adjust according to the position of the pair of movable mounting blocks and reciprocate to spray glue between the pair of movable mounting blocks, avoiding glue waste.

[0017] Each of the pair of movable mounting blocks has a threaded hole 20, and each threaded hole is provided with a limiting screw 21.

[0018] Since each of the pair of movable mounting blocks has a threaded hole and a limiting screw is provided in each threaded hole, the pair of movable mounting blocks can be completely limited on the mounting rod by the limiting screw.

[0019] Each of the pair of movable mounting blocks is equipped with a pair of indicator plates 22 for material size comparison.

[0020] Since each of the pair of movable mounting blocks is equipped with a pair of indicator plates for material size comparison, the position of the movable mounting block on the mounting rod can be better determined according to the indicator plates, so as to align it with the two ends of the material on the mounting roller.

[0021] A notch 23 is provided on the mounting frame below the top roller.

[0022] Because there is a notch on the mounting frame located below the top glue roller, the glue that naturally drips from the top glue roller can drip from the notch and fall back into the glue tank.
