Problems solved by technology

However, the extrusion of the mold will cause the deformation of the steel roller, resulting in jumping on the roller surface. If the runout exceeds 0.05mm, use a press to correct it to less than 0.03mm, and then use the cylindrical grinder to finely grind the outer circle to 0.02mm. within
Then carry out electroplating, because of the high temperature of electroplating, it will cause jumping, so the jumping of the actual factory-made glue rollers is generally between 0.02-0.03mm
In the process of cardboard production, in order to meet the basic bonding strength, it is necessary to ensure that the amount

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] During the specific implementation of the present invention, a 0.1mm nickel-chromium alloy primer layer is sprayed on the surface of the steel roller to prevent the iron core from being corroded by glue and rust; Ceramic surface, the accuracy can reach within 0.01mm. Laser engraving machine is used to engrave the texture on the surface of the ceramic. The amount of glue required by the customer of the network cable is different. It can engrave 20-60 lines of pyramid-shaped concave-point texture, honeycomb-shaped concave-point texture, pyramid-shaped convex-point texture, and honeycomb shape. Convex dot texture, used for glue transfer.

[0018] The high-precision gluing roller is guaranteed. At the same time, according to the viscosity of the glue, anti-sticking coatings such as Teflon can also be sprayed on the surface of the ceramic gluing roller to ...

Abstract

The invention discloses a ceramic glue spreader for paper packaging. The ceramic glue spreader comprises a steel roller arranged on the middle part of the ceramic glue spreader, nichrome priming coatof 0.15 mm is sprayed on the surface of the steel roller to protect an iron core from long-term corrosion by glue, a ceramic coating of 0.3-0.4 mm is sprayed on the outer layer of the nichrome primingcoat, a non-contact and pressureless laser engraving process is used on the ceramic coating to carry out net pattern carving on the ceramic surface, according to the difference of the viscosity of the glue, a Teflon anti-stick coating is sprayed on the surface of the ceramic coating, and the ceramic glue spreader is prepared. The roller surface accuracy, circular runout and roundness of the laserengraved ceramic glue spreader can finally reach within 0.005 mm, the glue spreading gap can be controlled within 0.05 mm, glue loss is reduced by about 20%, the spreading amount of the glue is moreeconomical, only a shorter drying time is required, energy consumption and carbon emission are reduced, the service life of the ceramic glue spreader can reach more than 6 times that of a chrome plated glue spreader, and meanwhile, environmental pressure caused by hard chromium electroplating is not caused.

Description

technical field [0001] The invention relates to the technical field of gluing rollers, in particular to a ceramic gluing roller for paper packaging. Background technique [0002] At present, on the single-sided machine of the corrugated cardboard production line, a set of rubber coating rollers and uniform rubber rollers are used to control the thickness of the glue by the surface texture of the rubber coating rollers and the gap between the rubber coating rollers and the rubber uniform rollers. After the corrugated paper is formed, pass The gluing roller applies a layer of glue on the top of the corrugated paper and combines it with the inner paper to form a single-sided corrugated paper. In addition, on the composite machine, there is the same set of glue rollers and cot rollers. Glue is applied to the top of another layer of single-sided corrugated paper, and then compounded with face paper or different types of single-sided corrugated paper to form three or five layers. ...
