Basic Assembling Unit
Manual loading vertical standing pulp loader unit: 2 roll system, pulp width = 500 mm
Milling system: standing fluff pulp holder, using sliding motor auto-lifting unit, avoiding load and unload problems, maximum pulp diameter ≤1400 mm; capacity: 800 kgs/hour; teeth-like type high-speed crusher, with insulative system can take untreated pulp, semi-treated pulp and treated pulp, maximum pulp width ≤500 mm, crusher motor power: 30 kW, pulp bursting strength: ≤1200 kPa, crusher quantity: 800 kg/hour; pulp feeding is controlled by frequency motor, feeding amount can be set on screen according to request, feeding amount can be automatic adjusted on the same level as to different speed, it will alarm and stop when detecting lace materials
SAP applicator: servo motor control; SAP spray evenly, softly; SAP weight: 2 to 20 g, feeding amount can be set on the touch screen according to request; double-screw type SAP adding unit mix with pulp and are wrapped after mixing; with continuous adding with fix quantity, auto detect the adding amount; level checking and alarming; electric eye detecting and auto lifting SAP to tank
Cotton core net square embossing unit, air-cylinder press
Cotton core is wrapped: the lower ply of tissue paper wraps the upper ply of tissue paper and cotton core inside; lower tissue unit: two shafts alternative usage for auto splicing, with frequency motor control (A/B shaft individual control), tension control, auto rejecting, auto-slicing materials without stopping machine, auto alarm when material breaks, auto checking and rejecting the material jointer, with edge-rectifier; upper tissue paper unit: two shafts alternative usage for auto splicing, with frequency motor control (A/B shaft individual control), tension control, auto rejecting, auto-slicing materials without stopping machine, auto alarm when material breaks, auto checking and rejecting the material jointer, with edge-rectifier
Folding section fold tissue on to the core
Cotton core cut off unit
Three rollers pulling and compaction unit I
Poly film loading unit: two shafts alternative usage for auto splicing, with frequency motor control (A/B shaft individual control), tension control, auto rejecting, auto-slicing materials without stopping machine, auto alarm when material breaks, auto checking and rejecting the material jointer, with edge-rectifier
Non-woven loading unit: two shafts alternative usage for auto splicing, with frequency motor control (A/B shaft individual control), tension control, auto rejecting, auto-slicing materials without stopping machine, auto alarm when material breaks, auto checking and rejecting the material jointer, with edge-rectifier
Folding section
Back sheet flanging unit
Longitudinal folding unit
Three rollers pulling and compaction unit II
Products cutting unit
Products are horizontally tri-folded or two folded
Auto-reject unit
Products are vertically outputted in one-line, auto counting
Equipped with safety guard glass
The driving system is servo motor driving system
Dust-collect system: 4 stack (bags), 4 feet off the ground
Knife holder is driven by universal shafts
There are 6-7 pieces of urgent-stop buttons on back turning doors
Waste-collect box
Guard all moving parts with enclosure or expanded metal
Covers for all crushers and vacuums to ensure the noise level is between 85-130 dB
Other equipment: there are lighting lamps on the parts of spraying glue and fixing lamps on the back driving parts; there is accounting unit; can do without pulp product, just two (or three layers) of tissue paper
Automatic System
Four sets of tension control system: one set each for PE film, hydrophilic nonwoven, lower tissue paper and upper tissue paper; the central unwinding is conducted by frequency motor, constant tension control, auto-off materials, splicing the materials under the condition of not speed-down
Four sets of edge-rectifiers: one set for PE film, hydrophilic nonwoven, upper tissue paper and lower tissue paper
Computerized control system (PLC – touching screen – servo motor control system)
With temperature controller on embossing roller temperature
There is manual switch for H.M. applicator on the screener, meanwhile the H.M. applicator can auto stop spraying and scraping the glue when the main machine stops working
The amount of SAP can be set on the screener
The amount of wood pulp supplying can be set on the screener
The output for single shift or total output can be shown on the screener
Auto gets rid of rejected products during splicing material; auto inspection on the jointers (it demands that there is fixed color on the joints of materials); the number of get-rid-of rejects can be set on the screener
Auto inspects and stops machine when material is used up
Turning up or slowing down the speed of main machine can be set on the screener; the speed of main machine during working time can be shown on the screener (pieces/minute)
Machine Frame and Construction
Machine frame used rectangle-pipe
Knife holder used Φ45 steel adjusting
