Equal RE CX250 multiple caliper disc brake for packing machine

Equal RE CX250 multiple caliper disc brake for packing machine

Handong made DBK250 full set of pneumatic multiple caliper disc brake can completely replace RE CX200, CX250, CX300, CX400, CX500 combiflex modular pneumatic brake. DBK250 CX250 is made of some modulars for produce different braking force. Full quantity is six, it max braking force is 960N.m.

DBK pneumatic caliper disc brake is a special air shaft friction brake, it can be composed of several pieces of points, such as one, two, four and six points. Different point quantity, its braking force is different. More points, braking force is larger, too. Handong made DBK250 cooling brake can well replace RE CX250 pneumatic caliper disc brake completely. This DBK250.6 pneumatic caliper disc brake can be used for braking and tension control as needed.

DBK model air applied caliper disc brake is composed of braking pads, piston, air chamber, fan cover, braking disc, fixed bolt, fixed frame and so on. This brake relies on air pressure to brake, return springs for release. After supplying air pressure, piston pushes friction pads moved toward to and compressed braking disc, producing resisting torque, until disc and other rotating parts stopped, brake linked. When exhausting air pressure, piston and friction pads back and separated with braking disc by return springs, brake released. 

Its response is sensitive, torque control precise. Piston sealing part is without oil. Lining thickness is 10mm, max abrasion is 6mm. When lining abrasion reached to 4mm, using screwdriver to take out head inside screw through hole of disc with hub to replace lining.  

This pneumatic points caliper disc brake is equiped with a cooling fan on the top of brake, it is good for heat dissipation. With this structure, it can reduce friction pads' surface temperature, so as to prolong DBK250 pneumatic caliper disc brake's service life.

This point pneumatic caliper disc brake is widely applied in aluminum foil, tissue, carton board, paper, plastic film, wire & cable and other industries. DBK air brake can be used as a brake and tension controller as needed. When DBK250 worked as a tension controller, it is usually matched with air expanding shaft, mechanical chuck or safety chuck together, like this:

In above case, full modular DBK250.6 multiple caliper disc brake is applied in paper packing machine, it is matched with mechanical chuck for large and heavy paper roller unwinding. In this situation, mechanical chuck is used to load and unload paper roller, and DBK250 multiple caliper disc brake is used for paper roller unwinding tension control, so as to make rolled and unrolled paper roller tension smooth and tidy.

This DBK250.6 pneumatic caliper disc brake, air shaft, steel bar, safety chuck together unit is widely applied in packing and printing machine, textile machine, non-woven fabric making machine, face mask machine, melt-blown fabric making machine and etc.
