Twin screw host SHJ-75-132kw—40:1

The sheet extruder is composed of extrusion, calendaring, traction and rolling. The main parts are abrasion resistant, resistant to corrosion, high-temperature resistant by high quality specially-treated. Low resistance force in die head extruding channel makes sheet thickness evenly, the internal spiral tank in three rollers ensures an effective cooling and it is easy to change and install net changer with the hydraulic pressure unit, no need to stop machine. The machine extrudes PP/PS/PET thermoforming machines, like cups, food container, trays, dishes, bowls, lids, etc.

Drive motor  qingdao cuishi plastic machinery ( www.cuishimachine.com )

Adopt variable frequency motor, with power of 132kw; Governor:

Select frequency converter;

Screw speed:30–300rpm; Power transmission:

coupling

Gearbox:High torque reducer.

Speed reduction and torque distribution are integrated to strengthen the design of bearing capacity;

The gear is made of high-quality alloy steel. After carburizing and quenching, the gear is precisely ground. The machining accuracy is above grade 5. The tooth surface hardness reaches hrc60-65. The tooth profile and helix are modified to ensure the perfect engagement of the gear under load, with low noise and large transmission torque;

The bearings are generally world-famous brands, such as NSK, FAG, TWB, SKF, ZWZ and HRB;

The oil lubrication system mainly adopts oil immersion lubrication and multi-point spray lubrication to ensure that all moving pairs are always lubricated;

New designed sealing structure and imported brand sealing ring ensure excellent sealing performance of input and output shafts;

Lubricating oil cooling: plate heat exchanger, circulating water cooling; Lubricating oil pump: built-in;

For the Pet electric drive system

62

Qingdao cuishi plastic machinery used Pet electric drive system is used to provide driving devices for various pet divisions, including main extrusion unit, cooling roller, traction unit and turnover double position winder. When the encoder feedback is adopted for the transmission device, the speed stability accuracy can reach 0.1%. Speed control and pressure control shall be realized for the transmission device of the extruder. High transmission accuracy is required for the main extruder and cooling roller,

3. to ensure the uniformity of longitudinal tolerance of PET sheet. Floating rolls or tension sensors are used for speed coordination between the three roll calender and the tractor.

4. the speed setting from the cooling roller to the traction unit is in a speed chain relationship to ensure that the linear speed of the production line is coordinated, and the linear speed of the production line can be given by the cooling roller according to the product specification, and can be set arbitrarily.

63

Vacuum pumping system two × 7.5kw 1 set (external structure) vacuum pump: water ring vacuum pump + roots pump, power 5.5 + 7.5kW;

Vacuum condensing tank: stainless steel vacuum condensing separation tank, equipped with tower plate filter water grid to facilitate the filtration of impurities and volatiles.

The two-stage structure of vacuum condensing tank can automatically control the removal of water, volatile matter and waste. The vacuum degree can be hardly affected during the removal process.

Hydraulic screen changer and gear pump system
