Description

Technical Field

[0001] The utility model relates to the technical field of alloy scrapers, and more specifically to an alloy scraper with a prolonged service life. Background Art

[0002] In the process of producing multi-layer products, there is a mismatch between the efficiency of conventional alloy scrapers and actual needs. Taking a four-layer product as an example, its structure may include two layers of surface paper and two layers of middle paper. The key is that the usage ratio of the surface paper and the middle paper needs to be matched to ensure product quality and cost control. There are significant differences in the durability of scrapers when processing different materials. The processing capacity of conventional alloy scrapers for surface paper can last for about 10 hours, while the processing capacity for middle paper can reach 30 hours. In theory, if the scraper is used to process both surface paper and middle paper, its combined use time can reach more than 40 hours. However, in actual production, this time is shortened to more than 20 hours due to material matching and production needs. In actual production, not so much middle paper may be needed, resulting in the high durability of the scraper in processing middle paper cannot be fully utilized. The mismatch between production planning or product design and scraper performance limits the actual utility of the scraper. Utility Model Content

[0016] 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.

[0017] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0018] Combination Figure 1-Figure 2The utility model discloses an alloy scraper with extended service life. The alloy scraper has a width of 114-115mm, a water absorption of 0, a bending inner diameter of ≥80cm, and includes a blade base and a blade edge. The blade base and the blade edge are fixedly connected. The blade edge directly acts on the drying cylinder and the paper surface. The thickness of the blade base is 1.2mm, the thickness of the blade edge is 1.3mm, the blade edge is heat-resistant to 500℃, the hardness of the blade edge is 1000-1100HV, and the straightness of the blade edge is 0.02mm / m. The straightness of the blade edge determines the uniformity of the alloy coating. The blade edge is provided with two use surfaces, A use surface 1 and B use surface 2, wherein A use surface 1 is the main use surface, and B use surface 2 is The alloy coating applied on the top of the blade and on the surface opposite to the A use surface 1 has a thickness of 0.1mm and a thickness error within ±0.05mm. The alloy coating thickens the blade and makes the blade more stable during use. The cross-section of the B use surface 2 is an inverted L-shaped structure, and the surface of the B use surface 2 is provided with texture. The setting of the texture is controlled by the thickness and density of the alloy coating. The concept of angle is eliminated and it is actually close to 0°. Due to the small contact angle, the friction between the blade and the material surface is reduced, which can reduce the heat generated by the scraper during operation and extend the life of the scraper. Through trial, on the premise of reaching a qualified feel, the starting degree is good.

[0019] Working process: The drying cylinder rotates at high speed, driving the paper on the drying cylinder to rotate and move toward the A use surface 1 of the blade. When the paper rotates to the A use surface 1 and comes into contact with the A use surface 1, the paper is separated from the drying cylinder and surface texture is generated under the wrinkling effect of the A use surface 1. During the use of the scraper, the alloy coating of the B use surface 2 makes the blade thicker, making the blade more stable during use.

[0020] In summary: the blade of the utility model is provided with two use surfaces, A use surface 1 and B use surface 2. A use surface 1 is the main use surface, and B use surface 2 is the auxiliary use surface with thickened blade. This design increases the service life of the scraper, and can make more fine lines. The fine line duration is increased by about 50% compared with conventional alloy scrapers. Since the matching fine line duration is increased, the actual comprehensive production time can be increased proportionally. The thickness density of the top main alloy coating is used to control the texture feel of the scraper, and actually achieves an angle close to 0°. This design helps to improve the use effect of the scraper and can significantly reduce the wrinkling rate of paper by up to 5-10 percentage points, which directly improves production efficiency and increases production capacity by at least 5 percentage points. On the premise of achieving the ideal paper feel, this scraper can also provide a good starting degree. The design of this scraper helps to more accurately control the weight of paper and avoid overweight.
