Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5As shown, the utility model provides a kraft paper coating production equipment, including a frame 1, a feeding system 2, a first kraft paper processing system 3 and a second kraft paper processing system 4 sequentially arranged on the frame 1, the feeding system 2 includes a feeding frame 201 movably arranged on the frame 1, a feeding drive module 205 arranged on the feeding frame 201, a track 104 and an ejection mechanism 101 are provided at the connection between the feeding frame 201 and the frame 1, and the feeding frame 201 is further provided with a wear-resistant layer feeding roller 202, a waterproof layer feeding roller 203 and a base paper layer feeding roller 204;

[0026] The first kraft paper processing system 3 includes a coating cabin 301, which is sequentially provided with a coating chamber 302, a first drying chamber 305, a cooling chamber 307 and a conveying channel 309. The coating chamber 302 is sequentially connected to the first drying chamber 305 and the cooling chamber 307. The coating chamber 302 is provided with a plurality of coating rollers 304 and an immersion tank 303 at the bottom of the coating chamber 302. The first drying chamber 305 is provided with a plurality of drying transmission rollers 306, and the cooling chamber 307 is provided with a plurality of cooling transmission rollers 308. The immersion tank 303 is also provided with a first pressing assembly 310, which is used to merge the material layers of the wear-resistant layer loading roller 202, the waterproof layer loading roller 203 and the base paper layer loading roller 204.

[0027] In this embodiment, a wet strength agent is added during the pulp preparation process, thoroughly stirred and mixed, and then papermaking is performed to form a base paper. The base paper is then surface-saturated with sizing agent and then combined with a waterproof layer and a wear-resistant layer to form a waterproof and wear-resistant protective layer. The base paper roll is placed on the base paper layer loading roller 204, while the wear-resistant layer loading roller 202 and the waterproof layer loading roller 203 are loaded with corresponding protective rolls. The material layers are initially laminated by a first laminating assembly 310. During the laminating process, the adhesive layer in the soaking tank 303 ensures that the waterproof and wear-resistant layers adhere tightly to the base paper layer. The base paper layer is also processed by a sizing machine before production. After the base paper is dried in a drying cylinder for the first time, a double-sided coating is applied using a sizing machine. After being saturated with the surface sizing machine, the base paper is dried in a drying cylinder for a second time, cooled, and rolled up to form masking paper.
