Product Detail

Transformer Insulation Paperboard Hot Gluing & Hot Pressing Machine (Φ250-3500mm, 2-8mm Thickness)

YIBO Paperboard Hot Gluing & Hot Pressing Machine delivers precision bonding for transformer insulation paper tubes. Designed for post-milling/rounding lap joints, it applies thermal oil heating (±2℃ accuracy) and hydraulic compaction (12MPa) to maintain thick cardboard tubes in a uniform hot-pressing state. Processing 2~8mm thickness, Φ250~3500mm diameter, and 1500~4000mm height, with 150mm bonding width (customizable). The integrated thermal oil heater and robust roller/plate structure ensure consistent adhesion, reduced bonding time, and high-quality insulation cylinders. Backed by YIBO’s 23+ years of transformer machinery expertise.

Description

1. Core Features & Advantages

① Uniform Hot Pressing for Thick Tubes

Keeps thick cardboard tube adhesive in a uniform hot-pressing state, ensuring reliable bonding quality and significantly shortening bonding time.

② Precision Thermal Oil Heating

Electric heating via thermal oil with adjustable 50~150℃ temperature and ±2℃ control accuracy. Upper pressing roller/plate and lower pressing plate deliver consistent heat distribution.

③ Powerful Hydraulic Compaction

Hydraulic system (12MPa pressure) compacts the lap joint firmly. Oil cylinder-driven pressing ensures stable force for 2~8mm thickness tubes.

④ Wide Tube Size Capability

Handles insulation paper tubes Φ250~3500mm diameter, 1500~4000mm height, and 2~8mm thickness. Bonding surface width 150mm (customizable per customer requirements).

⑤ Robust Structure & Composition

Comprises upper pressing roller (plate), lower pressing plate, oil cylinder, frame, and thermal oil heater temperature control system. Built for continuous transformer insulation production.
