Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating technology for impregnated paper, specifically a device for uniformly coating the back of impregnated paper with adhesive. Background Technology
[0002] Resin coating is a process in which resin or other adhesives are evenly coated onto the surface of paper to give it specific properties, such as improved strength, abrasion resistance, and insulation. It is commonly used in the field of engineered wood panel finishing.
[0003] The existing Chinese patent publication number CN215354388U, entitled "A Device for Uniformly Coating the Back of Impregnated Paper," explicitly states in its abstract that "This utility model relates to the field of impregnated paper coating technology, and in particular to a device for uniformly coating the back of impregnated paper, comprising a work panel, an adhesive coating mechanism disposed on the top of the work panel, a uniform coating mechanism disposed on the top of the work panel and in front of the adhesive coating mechanism, and a control panel disposed on the right side of the work panel. In this utility model, the device for uniformly coating the back of impregnated paper can uniformly coat the impregnated paper, improving the production efficiency of impregnated paper, reducing the rework rate of the paper, and collecting excess adhesive generated during the coating process, facilitating collection and processing, and reducing production steps and labor intensity."
[0004] However, this technology requires the use of a coating roller and a shaft to move the impregnated paper, and the coating roller to evenly apply the adhesive to the impregnated paper. However, the thickness of different impregnated papers is usually different. For example, furniture veneers may be thinner, while those used for architectural decoration may be thicker. This means that when the current device uses a shaft to transport the impregnated paper, if the impregnated paper is thin, the coating roller may not be able to contact the impregnated paper. As a result, the adhesive cannot be evenly applied to the impregnated paper, and excess adhesive cannot be squeezed out. If the impregnated paper is thick, it may not be able to pass between the coating roller and the shaft. This results in poor applicability of the existing device. Utility Model Content
[0005] The purpose of this invention is to provide a device for uniformly coating the back of impregnated paper, so as to solve the problem mentioned in the background art that the current devices have poor applicability due to the different thicknesses of the impregnated paper.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] Please refer to Figures 1-5 This utility model discloses a device for uniformly applying adhesive to the back of impregnated paper, including a mounting frame 1. The mounting frame 1 is the mounting structure of the device and is used to install other structures. A roller 11 is rotatably arranged on the bottom inner side of the mounting frame 1. Sliding grooves 14 are provided on both sides of the mounting frame 1. Sliding parts 2 are slidably arranged inside the sliding grooves 14. The sliding parts 2 are locked in the sliding grooves 14 and slide. An adhesive roller 12 is rotatably arranged inside the two sliding parts 2. The adhesive roller 12 and the roller 11 are the adhesive roller and roller structure in the background technology patent. That is, the impregnated paper is transported by the roller 11 and the adhesive is uniformly applied to the paper by the adhesive roller 12. A receiving groove 52 is slidably and detachably arranged at the bottom of the roller 11. Excess adhesive squeezed out will drip into the receiving groove 52.
[0028] The mounting bracket 1 is equipped with a second motor 22 at the top, and a screw 23 is installed on the drive shaft at the bottom of the second motor 22. The two sliding parts 2 are equipped with internal threaded strips 21 at the top. The screw 23 and the internal threaded strips 21 are threadedly connected. That is, the second motor 22 drives the screw 23 to rotate. Through the threaded transmission, the internal threaded strips 21 drive the sliding parts 2 on both sides and the glue coating roller 12 to rise and fall, thereby adjusting the distance between the glue coating roller 12 and the roller shaft 11, so as to evenly coat the glue-impregnated paper of different thicknesses.
[0029] A drive assembly is provided on one side of the mounting bracket 1. The drive assembly includes a driven gear 31 and a slide groove 24. A slider 33 is slidably disposed inside the slide groove 24. The slider 33 is engaged inside the slide groove 24 and slides. A synchronous pulley 32 is provided on one side of the slider 33, the driven gear 31, and the glue roller 12. A first motor 13 is provided on the other side of the mounting bracket 1. The drive shaft of the first motor 13 is connected to a roller 11. A drive gear 3 is provided on one side of the roller 11. The drive gear 3 meshes with the driven gear 31. The drive gear 3 and the driven gear 31 are of the same specification. The synchronous pulley 32 is located on the outer side of the slider 33. 2 is a rotating installation, while the driven gear 31 and the synchronous pulley 32 on the outer side of the glue-applying roller 12 are fixedly installed, that is, they rotate together with the driven gear 31 and the glue-applying roller 12. The driven gear 31 is a rotating installation, and the three synchronous pulleys 32 are meshed by a synchronous belt. The three synchronous pulleys 32 are of the same specification. That is, the first motor 13 drives the roller 11 to rotate, which can transport the glue-impregnated paper. At this time, through the drive gear 3 and the driven gear 31 on the other side, the outer synchronous pulley 32 is rotated, that is, the glue-applying roller 12 is rotated, and the rotation direction is opposite to that of the roller 11.
[0030] A rotating component 4 is rotatably mounted on the outside of the slide groove 24. The rotating component 4 is locked on the outside of the slide groove 24 and rotates. The rotating component 4 has a threaded opening 44 inside. A threaded rod 34 is mounted on one side of the slider 33. The threaded opening 44 and the threaded rod 34 are threadedly connected. A first gear 41 is mounted on the outside of the rotating component 4. A third motor 42 is mounted below the outside of the first gear 41. A second gear 43 is mounted on the drive shaft of the third motor 42. The second gear 43 meshes with the first gear 41. When the glue roller 12 moves up and down to a certain extent, the third motor 42 drives the second gear 43 to rotate, thereby causing the first gear 41 and the rotating component 4 to rotate. Through internal thread transmission, the slider 33 drives the synchronous pulley 32 on one side to slide, so that the synchronous belt of the meshing synchronous pulley 32 is in a taut state to ensure the transmission effect.
[0031] A rectangular groove 45 is provided on the upper outer side of the first gear 41. A retaining tooth 5 is slidably arranged inside the rectangular groove 45. The retaining tooth 5 meshes with the first gear 41. An electric push rod 51 is provided on the top of the rectangular groove 45. The telescopic end of the electric push rod 51 is connected to the retaining tooth 5. By pushing the retaining tooth 5 with the electric push rod 51, the bottom of the retaining tooth 5 is inserted into the first gear 41. Even if it cannot be inserted, the first gear 41 can be slightly rotated. At this time, the first gear 41 and the rotating part 4 can be fixed so that they cannot rotate, that is, the slider 33 cannot slide, ensuring that the timing belt of the meshing timing pulley 32 is always in a taut state.
[0032] The working principle of this utility model is as follows: The first motor 13 drives the roller 11 to rotate, which conveys the glue-impregnated paper. At the same time, the drive gear 3 and driven gear 31 on the other side drive the outer synchronous wheel 32 to rotate, which drives the glue-applying roller 12 to rotate in the opposite direction to the rotation of the roller 11. The roller 11 conveys the glue-impregnated paper, and the glue-applying roller 12 evenly applies glue to the paper. Excess glue squeezed out drips into the receiving groove 52. The second motor 22 drives the screw 23 to rotate. Through the threaded transmission, the internal threaded bar 21 drives the sliding parts 2 on both sides and the glue-applying roller 12 to rise and fall, thereby adjusting the distance between the glue-applying roller 12 and the roller 11. When the glue-applying roller 12 has risen and fallen to a certain extent, the third motor 42 drives the second gear 43 to rotate, which causes the first gear 41 and the rotating part 4 to rotate. Through the internal threaded transmission, the slider 33 drives the synchronous wheel 32 on one side to slide, so that the synchronous belt of the meshing synchronous wheel 32 is in a taut state to ensure the transmission effect.
