Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of copying paper production, and particularly relates to an improved coating machine doctor blade device. BACKGROUND

[0002] Common types of copying paper include B5, A4, B4, A3, 16K, 8K, etc. Among them, A4 is the most commonly used type, and its specifications are 210mm x 297mm. The specifications of A3 are 297mm x 420mm, and the area of A3 paper is equal to that of two A4 papers. In addition, the specifications of 8K are generally 290mm x 370mm, and the specifications of 16K are generally 185mm x 260mm or 185mm x 290mm.

[0003] The coating machine, also known as a brush coater, a doctor coater, a spray coater, etc., is a mechanical device driven by a motor or an engine, which is used to uniformly coat glue, paint, or ink with specific functions on the surface of a substrate, and then roll or cut it into pieces after drying. It is widely used in the surface coating processing of various materials such as film, paper, cloth, leather, aluminum foil, and plastic film to increase the properties or improve the performance of the materials, such as waterproof, fireproof, wear-resistant, and aesthetic.

[0004] After the doctor blade is damaged, its maintenance is usually difficult, and the main reasons are as follows: difficult to disassemble: the doctor blade is usually installed on the coating machine through fastening screws or pins, and specific tools and techniques are required for disassembly. If disassembled improperly, it may cause damage to the doctor blade or other parts of the coating machine, replacement is complex: when replacing the doctor blade, it is necessary to ensure that the size, model, and material of the new doctor blade are consistent with those of the old one, so that it can be smoothly installed and work normally. In addition, the doctor blade needs to be accurately adjusted to ensure that the gap and angle between the doctor blade and the coating roller reach the best state. The replacement and maintenance of the doctor blade usually takes a lot of time, and the preparation work is tedious: before replacing the doctor blade, the power of the coating machine needs to be turned off and the connection of related parts needs to be disconnected. At the same time, necessary cleaning and inspection of the coating machine are also required to ensure the smooth progress of the replacement process. The replacement process takes time: the disassembly, installation, and adjustment of the doctor blade usually take a certain amount of time, especially when the doctor blade is severely damaged or the coating machine structure is complex, the replacement process may take even more time. Testing and debugging: after replacing the doctor blade, the coating machine needs to be tested and debugged to ensure that the new doctor blade can work normally and achieve the expected coating effect. This process also takes a certain amount of time to complete. SUMMARY
