Three layer corrugated paperboard production line

Structural feature：

• adopt hydraulic drive to complete the paper clamping, loosen, remove for the medium, translation left and right and others，the lifting of the paper adopts hydraulic drive
• brake adjustable adopts multipoint braking system.
• every stand matched two sets paper car , and they can paper on the both sides at the same time.

Technical parameters：

Hydraulic system parameters：

Structural feature：

• the whole track buried . The main frame of the 14th Channel steel with ¢ 20mm cold drawn welded round，length of track6000mm
• each paper holder matched two sets paper trolley, and paper on both sides at the same time.pull the roller paper to the right place.

Structural features：

• The use of suction hood structure, with high – pressure strong fan. The air suction is equippe with sound attenuation device, and the air source and electrical control are concentrated in the same operating cabinet. The distance from the main machine is not less than 1.5m.
• The operating side is fully closed and covered.Machine base and wallboard cast iron structure, wallboard thickness of 130mm. Universal joint drive.
• The corrugated roller material is made of 48 crmo alloy steel, after tempering, medium frequency quenching, surface polishing, corrugated roller diameter ¢293 mm, surface hardness above HRC60 degrees (optional, tungsten carbide roll and surface hardness HV1400). Key parts of the tile roller, pressure roller bearings using wafangdian high temperature bearings.
• The pressure roller ¢320 mm, surface grinding and chrome plated treatment; The cylinder is controlled to move up and down, and the material is medium carbon steel no.45, tempering and tempering treatment (with buffer device).
• The pneumatic control to glue back glue, glue spreader with 25 ￠215 mm diameter surface after polishing line after pit type checker processing hard chromium plating processing, scraping the rubber roller surface after grinding hard chromium plating processing.
• Raw materials of corrugated roller and pressure roller are provided by zhongyuan special steel co., LTD. The corrugated roller has a top middle height of 0.15mm on one side and a middle height of 0.075mm on the other side. Add limit device.
• The preheat roll ¢diameter of 600 mm.

Roller diameter parameter：

1. corrugated roller diameter:   ￠293 mm
2. pressure roller:                       ￠320 mm
3. glue roller diameter:              ￠215 mm
4. preheater diameter:               ￠600 mm

Structural features：

1. Preheat roller accord with the national standard of the pressure vessal , and enclosed the pressure container certificate and inspection certificate.
2. Each roller surface after grinding precision grinding and dealing with hard chrome plating, Surface friction is small, durable.
3. Electric adjustable angle, it can rotated adjust the paper preheat area in the range of 360°.

Technical parameters：

Structural features：

1. After quenched of the glue roller surface,the hole machining, surface grinding and doing balancing engraved anilox pit type, coating evenly, less consumption of plastic
2. Glue roller turns is controlled by the frequency motor，by inverter control ensures glue roller line speed synchronous machine with double machine，they can operate independently
3. Electric adjustment display the glue amount。Automatic cycle for glue, glue avoid sedimentation, viscosity stability
4. Pneumatic structure platen gap by electric tuning. On the next floor are made independent variable frequency motor drive.
5. Take the speed signal of the double facer,so as to synchronous operation with it. Man-machine interface display, easy operation
6. Amount of glue automatic adjustment control ， amount of glue automatic adjustment with the produce speed, in automatic mode, you can also get in manual tuning.
