internal cam design to ensure stable high-speed operation.
Thickened wall panel, dual bearing transmission, large diameter stainless steel+45 # carbon steel composite coating roller, high-speed operation without glue throwing.
Advantages of stainless steel+45 # carbon steel composite drum: deep mesh pattern, uniform coating, more adhesive saving, therefore higher mounting flatness, good drum strength, no deformation, and never corrosion.
Peer merchants all use pure stainless steel rollers or chrome plated steel rods, with the following advantages and disadvantages:
Pure stainless steel roller: Good corrosion resistance, but insufficient strength and easy deformation.
Chromium plated steel rod: High strength, not easily deformed, but limited by the chrome plating process, the depth of the mesh is shallow, resulting in poor uniformity of the adhesive coating and easy
corrosion of the drum.
Servo rotary control valve
The bottom paper feeding section adopts a roller type leading edge feeding system, combined with a servo rotary control valve, which has a large air volume and is more stable for feeding curved cardboard and thick cardboard.
Disadvantages ofhigh-frequency electromagnetic valves: small air volume, high requirements for workshop environment, and long
term high-speed operation can easily cause electromagnetic valvejamming, resulting in unsmooth paper output, and difficult to
troubleshoot.
Shaftless transmission
The calibration channel for paper lamination adopts servo shaftless transmission, which has low vibration and higher lamination accuracy and low failure rate under high-speed operation.
At present, peers and friends all use shaft drive (one-way bearing structure or keyway shaft),
Disadvantages ofshaft transmission: high failure rate ofone-way bearing transmission structure, large shaking ofkeyway transmission structure, and poor fitting accuracy.
Adopting the principle structure ofdouble roller soaking and hanging water, ensuring uniform water supply and equipped with a water tray lifting structure,
it can be quickly disassembled and cleaned.
The single roller soaking water transfer type has uneven water supply, with a large amount ofwater at the front end and a small amount ofwater at the end,
which is very uneven.
