Name: CN300 High-Pressure Beam Rail Edge Banding Machine
Brand: CNSK
SKU: CN300

Overview

Sixteen cells in the order printed on the sheet: 21.5-inch industrial computer, high-pressure beam on a heavy steel rail, separating agent, pre-milling, heat lamp, 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 beam is a custom heavy section on a heavy steel rail: the load of a 60 mm door blank is carried by the rail rather than by the panel.
A two-colour PUR no-cleaning pot sits at station 06, and the heat lamp in front of it pre-heats the board and the glue.
Panels from 40 mm wide and 8 to 60 mm thick, band 0.4 to 3 mm thick and 12 to 65 mm wide.
16 to 23 m/min on a 9,280 mm frame, 950 mm wide and 1,800 mm high, with 22 kW installed.
The laser unit and its cooling head are optional on this frame: the sixteen cells above are the standard build, and the laser pair is quoted in addition.
Both scraping heads and the hinged flat scraper run ahead of the two polishing heads, so the edge comes off the line flat rather than merely trimmed.

Station sequence

Station 01 is the 21.5-inch computer and station 02 the high-pressure beam on its steel rail; the sixteen cells follow the order printed on the sheet. The sheet numbers the two scraping heads and the two polishing heads ① and ②, written here as 1 and 2.

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

Heavy-duty pressure beam

A custom heavy-section beam holds the panel flat while the band is pressed, which is what a door blank needs at 60 mm.

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

Heat lamp

The board and the glue are pre-heated before pressing, which keeps the bond even in cold weather.

06

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.

07

Swing-type pressing

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

08

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.

09

Scraping 1

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

10

Scraping 2

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

11

Hinged flat scraping

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

12

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.

13

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.

14

Cleaning

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

15

Polishing 1

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

16

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

High-pressure beam on a railThe beam is a custom heavy section carried on a heavy steel rail, so the panel is held flat while the band is pressed.
Two-colour PUR potThe no-cleaning pot switches between two adhesive colours without a solvent flush.
Double-stack disc trimmingTwo stacked discs trim the band top and bottom in one pass, which is what keeps a 60 mm edge square.
35° end trimming with evasionThe end heads cut at 35° and back off automatically on a thicker board or band, so corners are not chipped.
Hinged flat scrapingA hinged scraper follows the panel face and lifts surplus hot-melt off flat.
Two polishing headsPolishing 1 and 2 finish the edge, so the joint reads even against a lacquered door.
