Guolian High Speed ??Slitting Rewinder Technical Description ---
Part II: Hydraulic and pneumatic parts:
1. Hydraulic part:
The local hydraulic system consists of a hydraulic pump station and a valve station. System control and transmission components use world famous brand products. All hydraulic lines of the winder are supplied.
The hydraulic pump station uses three oil pumps to provide pressure oil source. The hydraulic station has safety facilities such as liquid level alarm, temperature control, filter blockage alarm, and a set of circulating filtration and cooling system. The valve station control section includes:
1) Ejection shaft ejection and locking device 2) Ejection frame movement 3) Ejection shaft clutch
4) Hook protection device 5) Paper core plug locking device 6) Press roller load reducing device
7) Unloader unit 8) Push roller unit 9) Stop roller holder lifting device
10) Ejection shaft hydraulic disc brake 11) Guide roller hydraulic disc brake
12) Front and rear bottom roller hydraulic disc brakes 13) Head lifting device.
14) Paper core positioning device 15) Paper head clamping lifting device
16) Automatic paper changer lifting device
The hydraulic circuit has the following features:
A. This system adopts superimposed valve, which is simple and compact in structure, convenient in maintenance and installation, and strong in work reliability;
B. The paper return shaft, the guide roller and the two bottom rollers are equipped with hydraulic disc brakes, which assist the brake during emergency braking and share part of the braking torque. Reduce the braking load of the motor, increase reliability, and install an accumulator;
Belt rewinding machine design and working principle ---
6 nipple guardrail
The nip guard is a sturdy mesh protector located between the belt roller and the unloader. The nipple guardrail acts as a protective device during the rewinding process. It prevents contact with rotating sticks.
The vertically moving fence is controlled by hydraulics. In the upper position, the safety lock prevents the fence from falling. When the guardrail falls, the cylinder compression safety lock opens.
The nipple is in the upper position when the reel is stopped. When rewinding, it must fall or the winder cannot be turned on.
7 paper feed roller
The reel is moved from the roll to the unloading station by a hydraulically controlled ejector mounted on the frame.
The minimum roll diameter that the pusher roll can be pushed open but cannot be pushed open with the smallest roll is 400 mm (15.7 in)
