It features a four\u2011head winding system and a touchscreen PLC-based control system for fully automatic operation from feeding and gluing to winding, cutting, and discharge.<\/p>\n<h3><strong>Q2:How does the four\u2011head winding system improve production?<\/strong><\/h3>\n<p>A2:The machine uses four synchronized winding heads that simultaneously wind the glued paper strips around a rotating mandrel, providing balanced force distribution, higher speed, and improved stability. This design yields significantly higher output compared to traditional two\u2011head systems.<\/p>\n<h3><strong>Q3:What are the key components and structure of the machine?<\/strong><\/h3>\n<p>A3:The main modules are the paper unwinding stand, automatic gluing unit, four\u2011head winding host, servo cutting system, and PLC control cabinet. Each module is designed for efficient feeding, precise gluing, multi\u2011head winding, accurate cutting, and automated control and monitoring.<\/p>\n<h3><strong>Q4:What is the range of applications and specifications of tubes produced by this machine?<\/strong><\/h3>\n<p>A4:The machine can produce paper tubes with inner diameters from 50 to 500 mm and tube thicknesses from 2 to 20 mm, with 3 to 35 layers of paper. It supports winding speeds up to 0\u201330 m\/min, cutting lengths from 300 to 5000 mm, and a cutting precision of \u00b10.5 mm, making it suitable for textile, film, plastic, paper, packaging, and construction industries.<\/p>\n<h3><strong>Q5:What are the notable advantages and operational benefits of this machine?<\/strong><\/h3>\n<p>A5:Notable advantages include high efficiency from multi\u2011station winding, precision PLC control with a memory capable touchscreen, durable construction for long service life, fully automatic production from feeding to discharging, wide application range, energy savings through frequency conversion (30\u201360% reduction in power usage), and easy maintenance with self\u2011diagnostic capabilities.<\/p>","protected":false},"featured_media":6817,"template":"","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center

with Four Heads PLC Control and what is its main purpose?","answer":"The Automatic 500mm Inner Diameter Spiral Paper Tube Making Machine with Four Heads PLC Control is a high\u2011volume, high\u2011precision industrial machine designed to produce spiral\u2011wound paper tubes. It features a four\u2011head winding system and a touchscreen PLC-based control system for fully automatic operation from feeding and gluing to winding, cutting, and discharge."},{"question":"How does the four\u2011head winding system improve production?","answer":"The machine uses four synchronized winding heads that simultaneously wind the glued paper strips around a rotating mandrel, providing balanced force distribution, higher speed, and improved stability. This design yields significantly higher output compared to traditional two\u2011head systems."},{"question":"What are the key components and structure of the machine?","answer":"The main modules are the paper unwinding stand, automatic gluing unit, four\u2011head winding host, servo cutting system, and PLC control cabinet. Each module is designed for efficient feeding, precise gluing, multi\u2011head winding, accurate cutting, and automated control and monitoring."},{"question":"What is the range of applications and specifications of tubes produced by this machine?","answer":"The machine can produce paper tubes with inner diameters from 50 to 500 mm and tube thicknesses from 2 to 20 mm, with 3 to 35 layers of paper.
