Name: CN380 CN380 Skeleton - line Door Panel Edger
Brand: CNSK
SKU: CN380

Overview

Fifteen cells in the order printed on the sheet: 21.5-inch industrial computer, track conveyor, separating agent, pre-milling, two-colour PUR no-cleaning pot, swing-type pressing, double-stack disc trimming, scraping 1, scraping 2, hinged flat scraping, 35° end and tail trimming, four-head tracking, cleaning, polishing 1 and polishing 2.
The crawler conveyor carries the panel, which is what keeps a 9400 mm door blank square through fifteen cells at 25 m/min.
A two-colour PUR no-cleaning pot at station 05 is the only glue station on this build; the EVA furnace and the laser pair are not in the fifteen cells.
Panels from 50 mm wide and 8 to 60 mm thick, band 0.4 to 3 mm thick and 12 to 65 mm wide.
16 to 25 m/min, the fastest feed in the CN group, on a 9,400 mm frame at 950 mm wide and 1,800 mm high.
22 kW installed, 380 V, 0.7 MPa air, electric lift on the pressure beam.
The laser operating system and its cooling unit are listed as optional on this frame, so a laser build is quoted on top of the fifteen cells.

Station sequence

Station 01 is the 21.5-inch computer and station 02 the track conveyor; the fifteen cells follow the order printed on the sheet, with the 35° end trimming at station 11.

01

21.5-inch control screen

Industrial-grade 21.5-inch screen with a large graphical interface; parameters set by touch or input box, changes shown live.

02

Track conveyor

A crawler conveyor supports the panel and drives it through every cell at constant speed.

03

Separating agent

A fine spray separates surplus glue from the panel face, so hot-melt does not mark the board after pressing.

04

Pre-milling

Two milling cutters re-finish the saw marks, burrs and out-of-square edges left by the panel saw, so the band seats on a clean face.

05

Two-colour PUR no-cleaning pot

The pot holds two PUR colours and switches between them without a solvent flush, and it sits outside the machine so the melt is kept apart from the EVA furnace.

06

Swing-type pressing

The pressure roller swings on an arc and cushions the load at the joint instead of hitting the band flat.

07

Double-stack disc trimming

Two stacked disc heads trim the band top and bottom in one pass, so the overhang comes off square to the panel face.

08

Scraping 1

The first scraping head takes the trim-knife marks and surplus glue off the upper edge of the band.

09

Scraping 2

The second scraping head repeats the pass on the lower edge, so both faces come off the band clean.

10

Hinged flat scraping

A hinged scraper follows the panel face and lifts surplus hot-melt off flat, with the angle set on the hinge.

11

35° end and tail trimming

The end heads cut at 35° and back off on their own when a thicker board or band comes through, so corners are not chipped.

12

Four-head corner tracking

Four driven heads round the corners at the leading and trailing ends, so the band follows the panel radius instead of cutting it square.

13

Cleaning

Residual hot-melt is diluted and isolated before polishing, so it lifts off instead of being smeared along the edge.

14

Polishing 1

Cotton wheels clean the finished edge on the first pass, taking the dust and the last of the glue off.

15

Polishing 2

The second pass finishes the edge after the first, for a higher sheen on the joint.

What the machine is built to do

Built around the door panelThe station list is sized for skeleton-line and framed doors: a wide pot, a heavy disc trim and ends that clear a grille.
Crawler bedA track conveyor drives the panel at constant speed, so a long door blank does not drift between the trimming and tracking heads.
Two-colour PURThe no-cleaning pot switches between two adhesive colours without a solvent flush, for doors where EVA fails or the joint must stay invisible.
Double-stack disc trimmingTwo discs trim the band top and bottom in one pass, which is what a 60 mm edge needs.
35° end trimmingThe end heads cut at 35° with automatic evasion, so a grille corner is not chipped.
Four-head trackingFour motors turn both corners, so the band follows the radius of the door edge.
