Embodiment Construction

[0028] Such as figure 1 As shown, the device for coating liquid viscous materials of the present invention includes a control unit and an unwinding unit 1 , a tension control unit 2 , a coating and printing unit 3 and a follow-up unit 4 arranged in sequence along the moving direction of the substrate 5 .

[0029] 1. Unwinding unit

[0030] The unwinding unit 1 includes an unwinding wheel 11, a tension control sensor 12, a deviation correction device 13, and several rollers 6. The power unit drives the unwinding wheel 11 under the action of a magnetic powder brake, so that the base material 5 is unrolled, and the base material 5 is provided with The tension sensor 12, the tension controller 12 and the magnetic powder brake of the unwinding unit 1 form a closed-loop control to ensure that the tension of the base material 5 remains constant, and can be regarded as set. A deviation correcting device 13 is also provided at the position of the unwinding unit 1 of the base material ...

Abstract

The invention discloses a three-roller coating printing unit for continuously coating the surface of a base material with a viscous material. The unit comprises a pressing roller, a driving silica gel roller and a driving steel roller which are stacked from top to bottom. The driving silica gel roller and the driving steel roller rotate in opposite directions, and a micron order gap is kept; the driving steel roller is soaked with a colloid pond containing the viscous material, the base material is arranged between the pressing roller and the driving silica gel roller, and the base material is supported on the supporting roller and moves in the centrifugal force direction of the top vertex of the driving silica gel roller under power traction. Under the effect that the viscous material is extruded, stretched and extended through rotating rollers with the two different rotating speeds and the opposite directions, a rubber layer of the certain thickness is formed on the surface of the rubber covered roller, the material is transferred to the surface of the continuously running base material by means of the pressing roller, the thin and uniform coating is formed, and materials of the micro order and submicron order thickness and thinner materials can be uniformly sprayed to the surface of the base material.

Description

technical field [0001] The invention belongs to the technical field of printing machinery, in particular to a device for spraying a thin layer of viscous material on a base material, in particular to a coating and printing unit for continuously coating the viscous material on the surface of a base material. Background technique [0002] Coating machines are widely used in the tobacco industry, packaging industry and energy manufacturing industry. In these industries, hot melt adhesive or other liquid viscous materials need to be sprayed onto the substrate or the surface of the substrate, and combined with subsequent processes to achieve moisture-proof or Manufacture the pole pieces of the battery. According to the process and product quality requirements, it is necessary to spray a thin and uniform layer of colloid on the surface of the rolled substrate material. For example, high-end environmentally friendly cigarettes in the tobacco industry often use polyethylene film co...
