Gum coating machines is an automated device that uniformly coats liquid adhesives, sealants, or coatings onto the surface of materials. Its main types and technical characteristics include:

1. Classification by Coating Method

Roller Coating

Structure: Adhesive is uniformly transferred to the material surface through the rotation of upper and lower coating rollers.

Features: Uniform coating, suitable for large-area or continuous production (e.g., plywood, textiles).

Adhesive application rate: The amount of adhesive applied is controlled by the roller gap and pressure, with an accuracy of ±0.01mm.

Representative Model: Four-roller gum coating machine (each roller has an extrusion roller, independently controlling the amount of adhesive applied to both sides).

Spray Coating

Structure: Adhesive is atomized and sprayed onto the material surface using air pressure or an electric spray gun.

Features: Suitable for complex shapes or localized coating (e.g., electronic components, automotive parts).

Spray thickness and time are programmable, supporting three-axis linkage path planning.

Representative Model: UV adhesive coating machine (employs UV curing technology for rapid positioning and miniaturized design). Dip Coating

Structure: After the material is dipped in adhesive, excess adhesive is removed by a scraper or pressure roller.

Features: Suitable for thin-layer coating (e.g., webbing, elastic bands).

The amount of adhesive applied is affected by the level of the adhesive tank and the scraper gap.

2. Classification by Automation Level

Manual Gum Coating Machine: Relies on manual operation, suitable for small batches or simple scenarios.

Automatic Gum Coating Machine: Integrates modules for feeding, coating, and curing, supporting mass production.

Intelligent Gum Coating Machine: Employs a six-axis articulated robot or a three-axis linear robot, combined with a vision system to achieve coating on spatial curved surfaces. Features constant temperature control, automatic cleaning, and logic algorithms to solve the problem of coating complex parts.
