Description

Technical Field

[0001] This utility model relates to the field of friction plate processing technology, specifically a friction plate adhesive coating device. Background Technology

[0002] Friction pads are components consisting of a chip and a friction liner or friction material layer, widely used in mechanical engineering, mechanical parts, and clutches. Grinding pads utilize a high-voltage electrostatic field to embed fine abrasive grains, specifically alumina or silicon carbide particles, onto a high-strength polyester film, ensuring all grains point outwards for sharp cutting, resulting in higher grinding efficiency and a bright, fine finish. They are then processed through backing and cutting. The friction pads and horseshoes require adhesive bonding, necessitating the use of an adhesive applicator.

[0003] For example, Chinese Patent Publication No. CN217857019U discloses the following technical solution: a friction pad coating device, including a support base, a rotating column rotatably mounted on the support base, a pad at the upper end of the rotating column, and several sets of sleeve rods rotatably mounted on the pad, with a placement plate fixed to each set of sleeve rods; a fixed frame is provided on one side of the support base, a transverse cylinder is installed on the inner side wall of the fixed frame, a connecting plate is provided at the movable end of the transverse cylinder, and a sprayer is installed on the connecting plate; a crossbeam is connected to the upper end of the fixed frame, an electrically controlled push rod is installed at the upper end of the crossbeam, and a scraper is connected to the movable end of the electrically controlled push rod; a first motor is installed at the lower end of the support base, the output shaft of the first motor is driven and connected to the rotating column, and several sets of second motors are installed at the lower end of the pad, each second motor corresponding to a sleeve rod, and the output shaft of the second motor is driven and connected to the sleeve rod. This utility model makes the coating of the friction pad surface uniform and consistent, and effectively improves the coating efficiency.

[0004] The above-mentioned technology requires a separate motor to drive the rotation of each placement plate during the glue application process, which increases the glue application cost. Therefore, a friction plate glue application device is proposed to solve the above problems. Utility Model Content
