1.1.2 Structure specification

1.1.2.1 framework

It adopts profiled jointing and has higher rigidity. The whole stand frame is made up of two wall planks, tip join

plank and pedestal. Each installment is passed machine process to ensure the precision of installment

1.1.2.2 Driving system

Gearbox adopts the skew gear worm-gear box(Redsun),smooth driving, Low noisy and high efficiency.

power:4.4kw/roller

1.1.2.3 Rollers

a) Roller diameter:φ420mm

b) Roller control warm water pass in and out caliber:11/4”

c) circularity:0.005mm

d) concentricity:φ0.012mm

e) surface roughness:Ra0.025μm

f) convex in the middle:none

g) Quench-hardening of roller top circle face is above HRC45, and the depth of quench-hardening is 3~5mm

h) The roller-edge face is plated hard chromium,t=0.10~0.15

i) Roller lined tank, rotating lined tank, 6 heads

j) Roller bearing set:adopt Double row cylindrical roller bearings-

k) bearing housing: adopt steel castings,after tempering treatment,high rigidity. It can change the roller

quickly. There is a lubrication hole in the lid, easy for Maintenance

l) Both side of roller provided with Retaining ring,used for removing the bearing

1.1.2.4 Distance-adjusted device for roller

a) Sloping block direct space-adjust

b) Distance between rollers is kept by hydraulic controlled system, and the pressure is stable and credible

1.1.2.5 Moving Units

The whole moving mould is made up of driven system,jack

a) units etc

b) Motor power:0.37kw

c) Adopt double reduction final drive,moving smooth

1.1.2.6 Hydraulic control system

The main function of the hydraulic system is to keep the distance of two rollers, make the plastic comes out from

mould stabilize molding in a certain pressure, and ensure the product surface cleanness and thickness

accordance

System max pressure:P=80kg/cm2

System Min. pressure:P=65kg/cm2

gas filled pressure:P=50 kg/cm2

oil pump displacement :4cm3/rev

1.1.2.7 Electric control box

a) Independent electric control box:Schneider AC contactor

b) Independent servo control for 3 rollers :AC servo control system,The rollers can be adjusted either as a

whole, or individually for mini-adjusting
