Description

Technical Field

[0001] This utility model relates to the technical field of adhesive coating mechanisms, specifically an adhesive coating mechanism for soft and durable sandpaper. Background Technology

[0002] Sandpaper is a tool used for grinding and polishing material surfaces. It is typically made of a paper or fiber cloth substrate and covered with abrasive particles of varying coarseness. These abrasive particles can be natural minerals such as corundum and quartz sand, or synthetic materials such as silicon carbide and alumina. Sandpaper has a wide range of applications, including woodworking, metalworking, automotive repair, and furniture manufacturing. During the sandpaper processing, it needs to be coated with adhesive, requiring a soft, foldable adhesive coating mechanism.

[0003] Chinese Patent Publication No. CN218132893U discloses a decorative paper coating mechanism, belonging to the field of decorative paper processing technology. It includes a tension adjusting frame and a coating assembly. The tension adjusting frame includes a frame, a first guide roller, a transmission assembly, two rotating shafts, two gear discs, two tension rollers, and multiple mounting rods. The two ends of the first guide roller are rotatably mounted on the frame via bearings. The two rotating shafts are symmetrically mounted on the frame via bearings and fixedly connected to the multiple mounting rods. Both ends of the two tension rollers are mounted on the mounting rods. This reduces surface relaxation, minimizes wrinkles, and improves coating quality. Two contact rollers mounted on the lifting frame, along with a brush plate, allow the glue to drip from the drip tube onto the coating hollow rollers for even coating, facilitating uniform application of the glue to the decorative paper surface while minimizing contact with the paper and preventing damage.

[0004] Although the above-mentioned glue application mechanism can evenly apply glue to the hollow glue application roller by dripping glue from the drip tube through the brush plate, making it easier for the glue to be evenly applied to the surface of the decorative paper and reducing contact with the decorative paper to avoid damage, the glue application mechanism is generally a relatively fixed structure, which makes it inconvenient to replace the glue roller and glue box according to the work needs, resulting in inconvenience in use. Therefore, we propose a glue application mechanism for soft and fold-resistant sandpaper. Utility Model Content

[0005] The purpose of this utility model is to provide a gluing mechanism for soft and durable sandpaper, so as to solve the problem mentioned in the background art that the general gluing mechanism has a relatively fixed structure, which makes it inconvenient to replace the glue roller and glue box according to the work needs, resulting in inconvenience in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gluing mechanism for soft, fold-resistant sandpaper, comprising:

[0007] A processing table, wherein positioning plates are installed on both sides of the processing table, and paper rolls are installed on the inner side of the positioning plates;

[0008] A limiting frame is disposed above the paper roll. A glue storage mechanism is installed inside the limiting frame, and an elastic pressure plate is disposed above the glue storage mechanism. A telescopic spring is connected above the elastic pressure plate.

[0009] A clamping plate is installed on one side of the limiting frame. A drive motor is installed at one end of both the clamping plate and the paper roll. A glue-spreading roller is installed on the inner side of the clamping plate, and a linkage block is connected above the glue-spreading roller. A bidirectional push rod is connected to the inner side of the linkage block.

[0010] Preferably, the positioning plate further comprises:

[0011] A positioning plate is connected to the outside below the positioning plate, and a fixing pin is installed inside the positioning plate.

[0012] Preferably, the drive motor and the paper roll form a rotating structure, and the paper roll and the positioning post are detachably connected.

[0013] Preferably, the glue storage mechanism and the limiting frame are engaged with each other, and the elastic pressure plate forms an elastic structure with the glue storage mechanism through the telescopic spring.

[0014] Preferably, the limiting frame further includes:

[0015] Nut blocks are installed on both sides of the limiting frame. A conveying screw is installed inside the nut block, and one end of the conveying screw is connected to a conveying motor. The nut blocks are fixedly connected to the limiting frame, and the glue storage mechanism is perpendicular to the processing table.

[0016] Preferably, the bidirectional push rod forms a telescopic structure with the clamping plate through the linkage block, and the drive motor forms a rotating structure with the glue-spreading roller.

[0017] Preferably, the coating roller is further provided with:

[0018] A drying mechanism is installed on one side of the glue-spreading roller, and the drying mechanism is parallel to the processing table.

[0019] Compared with the prior art, this utility model provides a glue-applying mechanism for soft and fold-resistant sandpaper, which has the following beneficial effects:

[0020] This invention uses a limiting frame to limit the position of the glue storage mechanism. The telescopic spring allows the elastic pressure plate and the glue storage mechanism to extend and retract relative to each other, thus facilitating the installation and positioning of the glue storage mechanism. The bidirectional push rod can drive the linkage block and the clamping plate to extend and retract relative to each other, thus facilitating the loading and unloading of the glue-spreading roller. This avoids the problem of the relatively fixed structure of general glue-spreading mechanisms, which makes it inconvenient to replace the glue roller and glue box according to work needs, causing inconvenience in use.

The installation and positioning of the glue storage mechanism 8; the clamping plate 11 is installed on one side of the limiting frame 7, and a drive motor 6 is installed at one end of both the clamping plate 11 and the paper roll 5. The drive motor 6 and the paper roll 5 form a rotating structure, and the paper roll 5 is detachably connected to the positioning post 2. The drive motor 6 can drive the paper roll 5 to rotate, so that the paper rolls on both sides can be unwound and rewound synchronously. A glue-spreading roller 12 is installed on the inner side of the clamping plate 11, and a linkage block 13 is connected above the glue-spreading roller 12. A bidirectional push rod 14 is connected to the inner side of the linkage block 13. The bidirectional push rod 14 forms a telescopic structure with the clamping plate 11 through the linkage block 13, and a rotating structure with the glue-spreading roller 12. The bidirectional push rod 14 can drive the linkage block 13 and the clamping plate 11 to extend and retract relative to each other, so as to facilitate the loading and unloading of the glue-spreading roller 12. The drive motor 6 can drive the glue-spreading roller 12 to rotate, so as to facilitate the even application of glue on the sandpaper.

[0028] Please see Figure 1 and 4 A gluing mechanism for soft, fold-resistant sandpaper includes: a nut block 16, which is installed on both sides of a limiting frame 7; a conveying screw 17 is installed inside the nut block 16, and one end of the conveying screw 17 is connected to a conveying motor 18; the nut block 16 is fixedly connected to the limiting frame 7; and a glue storage mechanism 8 is perpendicular to the processing table 1. The conveying motor 18 can drive the conveying screw 17 to rotate, and the rotating conveying screw 17 can vertically move the nut block 16, the limiting frame 7, and the glue storage mechanism 8, thereby sending the glue storage mechanism 8 to the sandpaper outlet for easy application of glue to the sandpaper; and a drying mechanism 15, which is installed on one side of a glue-spreading roller 12 and is parallel to the processing table 1. The drying mechanism 15 can dry the evenly applied glue to prevent glue from overflowing during subsequent winding.

[0029] Working principle: When using the soft and durable sandpaper coating mechanism, first install the paper roll 5 inside the positioning post 2, then insert the fixing pin 4 into the positioning plate 3 to position it relative to the processing table 1, thus fixing the positioning post 2. Then pull out the sandpaper and fix one end to the paper roll 5 on the other side. Next, install the glue storage mechanism 8 inside the limiting frame 7. The telescopic spring 10 causes the elastic pressure plate 9 and the glue storage mechanism 8 to extend and retract relative to each other, thus facilitating the installation and positioning of the glue storage mechanism 8. Then install the glue spreading roller 12 inside the clamping plate 11. Start the bidirectional push rod 14. The bidirectional push rod 14 drives the linkage block 13 and the clamping plate 11 to extend and retract relative to each other until the glue spreading roller 12 is clamped and positioned by the clamping plate 11. Then start the transmission motor 18. The transmission motor 18 drives the transmission screw 17 to rotate, and the rotating transmission... The lead screw 17 can vertically move the nut block 16, the limit frame 7, and the glue storage mechanism 8, thereby sending the glue storage mechanism 8 to the sandpaper. Opening the glue storage mechanism 8 allows glue to be applied to the sandpaper. Then, the drive motor 6 is started, which drives the paper roll 5 to rotate, so that the paper rolls 5 on both sides can be unwound and rewound synchronously. Finally, the drive motor 6 can drive the glue spreading roller 12 to rotate, which facilitates the even application of glue on the sandpaper. At this time, abrasive is added to the glue, and the abrasive will adhere to the glue. Then, the drying mechanism 15 is started, which blows out a small amount of hot air, which can dry the evenly applied glue without blowing away the abrasive. At the same time, it can accelerate the adhesion between the abrasive and the glue, and also prevent the glue from overflowing when it is not dry during subsequent rewinding. This is the working principle of the glue application mechanism for soft and durable sandpaper.
