[0002] The full name of melamine impregnated paper is melamine impregnated film paper, also known as "melamine" paper. It is a kind of plain base paper or printed decorative paper that has been impregnated with amino resin and dried to a certain degree. It has a certain resin content and volatile matter content. It can be glued to each other or to the artificial board substrate by hot pressing; the coating equipment of melamine impregnated paper is a key link in the manufacturing process, which can enhance the physical properties of paper such as wear resistance, pollution resistance and impact resistance, while improving its aesthetic effect.

[0003] In Chinese patent CN218880450U, a melamine impregnated paper secondary coating device is disclosed, which starts a dryer to generate hot air inside the installation cylinder and blows it toward the wind hood, so that the impregnated paper raw material is directly dried after the secondary coating; through the arrangement of the guide hood, air outlet pipe, chute, activated carbon filter and fan, most of the odor is absorbed, thereby preventing the odor from spreading into the air.

[0004] The above invention is combined with the existing technology. In the process of realizing this application, the inventor found that there are at least the following problems in this technology. When the existing melamine impregnated paper is transported to the coating equipment, its surface will inevitably be sticky with dust, but the coating equipment generally directly coats the surface of the paper, which may cause the flatness and aesthetics of the paper to be poor after the paper is coated, resulting in poor coating effect, so further improvement is needed. Utility Model Content

A wiping cloth layer is detachably installed on the right side of the pressure plate, and the dust removal rubber roller is in contact with the wiping cloth layer.

[0008] Furthermore, the adjustment mechanism includes a positioning slide rail and an adjusting cylinder. There are two positioning slide rails, and the front and rear positioning slide rails are respectively fixedly installed on the front and rear sides of the roller conveyor. A sliding support plate is slidably installed inside the positioning slide rail. There are two adjusting cylinders, and the two adjusting cylinders are respectively fixedly installed on the front and rear sides of the bracket.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 A coating device for melamine impregnated paper in this embodiment includes a coating and drying mechanism 3 and a roller conveyor 2 arranged at the bottom thereof, a bracket 1 is fixedly installed at the bottom of the roller conveyor 2, an adjusting mechanism is arranged outside the roller conveyor 2, and a cleaning mechanism is arranged inside the adjusting mechanism.

[0019] Among them, the coating and drying mechanism 3 is an existing known device, so it will not be described in detail in this article.

[0020] In this embodiment, the cleaning mechanism includes a servo motor 9, a dust removal rubber roller 12 and a spring telescopic rod 13. The servo motor 9 is fixedly installed on the front of the adjusting mechanism. The dust removal rubber roller 12 is fixedly installed on the output end of the servo motor 9. The dust removal rubber roller 12 penetrates and extends into the interior of the adjusting mechanism. The spring telescopic rod 13 is fixedly installed on the left side of the inner wall of the adjusting mechanism. A pressure plate 14 is fixedly installed on the right side of the overall output end of the spring telescopic rod 13. A wiping cloth layer 15 is detachably installed on the right side of the pressure plate 14, and the dust removal rubber roller 12 is in contact with the wiping cloth layer 15.

[0021] It should be noted that the wiping cloth layer 15 is fixedly connected to the pressure plate 14 by Velcro, so that the wiping cloth layer 15 can be easily disassembled for cleaning or replacement; the setting of the spring telescopic rod 13 allows the user to squeeze the pressure plate 14 to move to the left, so as to quickly replace the wiping cloth layer 15. After the replacement is completed, the spring telescopic rod 13 is restored to make the wiping cloth layer 15 continue to contact with the dust removal rubber roller 12 to ensure the cleaning effect.

[0022] The wiping cloth layer 15 is a cotton cloth moistened with a little cleaning liquid, so that the surface of the dust removal rubber roller 12 can be gently wiped to increase the service life.

[0023] Specifically, the paper is placed on the left side of the roller conveyor 2 for transportation, and the servo motor 9 is started to rotate the dust removal rubber roller 12, thereby electrostatically adsorbing the dust attached to the surface of the paper. At the same time, the dust removal rubber roller 12 contacts the wiping cloth layer 15 during rotation, so that the wiping cloth layer 15 wipes the dust on its surface, thereby ensuring the use effect of the dust removal rubber roller 12 for a longer time.

[0024] In this embodiment, the adjustment mechanism includes a positioning slide rail 4 and an adjusting cylinder 6. The number of the positioning slide rails 4 is two, and the front and rear positioning slide rails 4 are respectively fixedly installed on the front and rear sides of the roller conveyor 2. A sliding support plate 5 is slidably installed inside the positioning slide rail 4. The number of the adjusting cylinders 6 is two, and the two adjusting cylinders 6 are respectively fixedly installed on the front and rear sides of the bracket 1. The output end of the adjusting cylinder 6 is fixedly connected to the sliding support plate 5. A protective shell 7 is fixedly installed on the top of the sliding support plate 5 as a whole, and an infrared sensor 10 is fixedly installed on the bottom of the protective shell 7. A through hole 11 is opened at the bottom of the protective shell 7. A dust removal rubber roller 12 passes through the through hole 11 and extends to the bottom of the protective shell 7. The length of the infrared sensor 10 from the roller conveyor 2 is greater than the length of the dust removal rubber roller 12 from the roller conveyor 2. The spring telescopic rod 13 is fixedly installed on the left side of the inner wall of the protective shell 7, and a top cover 8 is embedded on the top of the protective shell 7.

[0025] Among them, the infrared sensor 10 is located on the left side of the dust removal rubber roller 12, so that the distance from the paper to the dust removal rubber roller 12 can be detected in advance, and the data can be transmitted to the external central control device, so that the external control device controls the adjustment cylinder 6 to operate.

[0026] Specifically, when the infrared sensor 10 detects the distance information between the paper and the dust removal rubber roller 12, the adjusting cylinder 6 is started through the external central control device to move the sliding support plate 5 downward inside the positioning slide rail 4, so that papers of different thicknesses contact the dust removal rubber roller 12, thereby avoiding the possibility of paper damage and improving the overall applicability of the device.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
