High-speed wax coating apparatus

Abstract

The present invention relates to a high-speed wax coating apparatus, which comprises a base paper pre-heating assembly for carrying out a pre-heating treatment on base paper before wax coating, a wax melting chamber assembly arranged on the rear portion of the base paper pre-heating assembly and holding a wax liquid for wax coating of the pre-heated base paper conducted to the chamber, a wax feeding assembly having a disk type structure, a wax rubbing roller arranged on the rear portion of the wax melting chamber assembly and used for avoiding wax liquid temperature reduction when contacting the paper surface wax liquid, and a cooling roller arranged on the rear portion of the wax rubbing roller, wherein the lower half portion of the wax feeding assembly is soaked into the wax melting chamber assembly and coats the wax liquid onto the base paper in a rotating manner, and the wax liquid coated on the base paper is cooled in a rapid cooling manner through the cooling roller. Compared with the apparatus in the prior art, the apparatus of the present invention can ensure the stability and the uniformity of the wide-width high-speed wax coating.

Description

technical field [0001] The invention relates to a waxing device, in particular to a high-speed waxing device which ensures the stability and uniformity of wide-width high-speed waxing. Background technique [0002] Waxed paper is widely used in food, medicine, sanitary products, stationery, measuring tools, knives and other packaging. With the continuous improvement of people's living standards and the increasing emphasis on food hygiene and safety, the quality requirements for paper-based waxed products are also continuously increasing. The traditional wax paper production technology mainly includes: immersion waxing method, this method is to completely immerse the paper into the molten wax, and then squeeze the excess wax off the surface of the paper through a pair of extrusion rollers. Its biggest disadvantage is that it is impossible to control the coating amount of wax. Too much wax on the wax paper is easy to gather and fall off locally during the packaging process, c...

Its biggest disadvantage is that it is impossible to control the amount of wax coating. Too much wax on the wax paper is easy to gather and fall off locally during the packaging process, causing pollution to the packaged food

[0003] The Chinese patent application number 201120569182.6 discloses a waxing device that can control the coating amount and coating position. The anilox roller is fixed on the main drive shaft, and the glue roller is arranged in parallel above the anilox roller. The roller is fixed on the rotating shaft, and the two ends of the rotating shaft are installed in two rotating shaft bearings, each rotating shaft bearing is installed in a rotating shaft bearing seat, and each pressing roller cylinder corresponds to a rotating shaft bearing seat, and the pressing The piston rod on the cylinder of the roller is connected with the bearing seat of the rotating shaft, the cylinder of the press roller is connected through the frame, the tip of the scraper is located on the anilox roller on the input side of the anilox roller, the scraper is installed on the knife holder, and the knife holder is connected with the anilox roller. The scraper lifter is connected, the scraper lifter goes up and down along the frame, the wax tank is set under the anilox roller, the wax tank is installed on the wax tank lifter, and the wax tank lifter goes up and down along the frame, but the operating speed of the device is only It can be around 60 meters. If the speed goes up, the amount of wax applied will be unstable, the phenomenon of wax flying, the wax layer will be reversed, etc. The phenomenon of ignoring the product will be exposed, and there is also a lack of wax rubbing rollers, which use cold air for cooling The effect is limited, which is one of the reasons why the device cannot achieve high-speed operation
