Equipped with pneumatic mechanical mechanism to ensure perfect clamping of the core, safe operation, durable and flexible. Pneumatic mechanical chuck is usually used in industries with large roll diameter and high load, such as corrugated board production.
The front face of the chuck is rotated to a certain angle by a rotating torque, and the key bar expands outward and compresses the coiled tube. After the rotation torque is released, the key bar automatically returns to its position.
Advantages: strong bearing capacity, not easy to loosen, no coiling, saving time.
The rotary core clamp uses the torque generated by the braking force and the coil tension reaction force (coupled with the brake or motor) to expand the sector parts, automatically locate and lock the core.
The fan-shaped part with large contact surface ensures the maximum control of the roll and reduces the damage to the core of the cardboard roll, so that the core can be reused.
In the rewinding equipment, the cone-shaped base paper chuck used in the base paper rack of the corrugated cardboard production line has the disadvantage of breaking the base paper core and inner edge paper during use, which makes it difficult to use the tail paper and the tail paper is scrapped. The rate exceeds two per thousand. The automatic expansion type base paper chuck does not require power assistance. After the paper is successfully threaded, the chuck sliding plate will automatically expand and expand in the base paper core with the gravity rotation of the base paper to support the paper core or automatically contract to remove the paper core, which completely solves the problem of cone The shape-shaped base paper chuck breaks the disadvantages of the tail paper and improves the utilization rate of base paper.
1. It is suitable for various rewinding shafts of slitting machine, printing machine, rewinder, bag blowing machine, bag making machine…etc.
2. According to customer needs, professional evaluation, design and manufacture [size from 1″(25mm)~12″(300mm)], special specifications, special tension, and special surface treatment can be produced.
3. All kinds of special environments (dust-free, corrosive, high temperature environment) are applicable.
NEB type side push mechanical chuck, the most suitable side push chuck for hydraulic paper holder. When the hydraulic support arm moves and pushes sideways, the fan-shaped structure expands and fixes the material pipe and automatically centers it. Larger contact area damages the material pipe. Multiple specifications, high load-bearing capacity, maintenance-free, long life, simple operation, and reduce the risk caused by heavy handling.
Equipped with pneumatic mechanical mechanism to ensure perfect clamping of the core, safe operation, durable and flexible. It can be designed and manufactured into single diameter and double diameter, both of which are suitable for 70mm to 12 “diameter cores and loads up to 40000N. Pneumatic mechanical chucks are usually used in industries with large coil diameters and high loads, such as corrugated board production.
The axial thrust mechanical core chucks has a spring system, which expands a series of keys and locks the core. Mechanical chucks are designed as single diameter and double diameter types, both suitable for 3 “to 12” cores and up to 150000 N loads. There are also special models with center positioning hole and pop flange. The center positioning hole is used for roll alignment and positioning.
