Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 , figure 2 It is a schematic diagram of the structure of the existing coating head, and the components 15-20 are the existing structures.

[0019] Such as figure 1 As shown, a coating roller 20 is included, and the coating substrate 15 moves around the coating roller 20, and a comma scraper 17 and a material blocking plate 19 are correspondingly arranged above the coating roller 20, and the comma scraper 17 is installed on the scraper swing arm 16, Slurry 18 is contained in the triangular area that cooperates between the coating roller 20 and the baffle plate 19 .

[0020] The action process under normal conditions is that when the coating roller 20 rotates, the slurry 18 passes through the pre-adjusted uniform gap between the comma scraper 17 and the coating roller 20 under the guidance of the coating substrate 15, and th...

Abstract

The invention discloses a wallpaper coating adsorption mechanism. The wallpaper coating adsorption mechanism is characterized in that a cylinder support is fixedly installed on a scraper swing arm; a rodless cylinder is fixedly installed on the cylinder support and is communicated with a gas inlet and outlet pipe and a gas outlet and inlet pipe; a transition pipe is installed at the upper end of the rodless cylinder; an adsorption pipe is communicated with one end of the transition pipe; the front end of the adsorption pipe extends into a remainder region; the other end of the transition pipe is communicated with one end of a three-way cavity; the lower end of the three-way cavity is communicated with a collection cavity; the other end of the three-way cavity is connected with an air suction device. The device has the beneficial effects that the coated substrate is not affected by remainders by adding the adsorption mechanism to existing coating heads of coating machines, so that the problem of coated substrate waste caused by the remainders after coating is thoroughly solved, and the whole coating process is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of printing machinery and equipment, and relates to a wallpaper coating and adsorption mechanism. Background technique [0002] At present, in the wallpaper production process, the coating method mostly uses a comma scraper to coat the wallpaper substrates, which include paper, non-woven fabrics, natural plants and other materials. Throughout its production process, no matter what substrate is used, coating is inseparable. [0003] When the comma scraper is coating many substrates, due to the high-precision coating requirements and the structure of the comma scraper itself, the scraper is fixed and does not rotate when scraping glue on the knife edge, so the coating thickness can be well controlled. However, as time goes by, some tiny, irregularly shaped lumps of excess will slowly accumulate on the back of the comma scraper. These excesses will be transformed into a solid state after a period of time when ...
