DBK250 air disc brake use in high accuracy tension control situation, can provides many kinds of torque control, has a great ability of radiation, can have a widely application in processing of industries, as the packing, tissue paper and corrugated paper.
According to the use, it can be divided into: papermaking rubber roller, printing and dyeing rubber roller, printing rubber roller, grain hulling rubber roller, metallurgical rubber roller and mimeograph rubber roller, etc.; The rubber roller is generally composed of outer layer rubber, hard rubber layer, metal core, roller neck and vent hole. Its processing…
The inflating operation time of the air expanding shaft is short. It takes only 2 seconds to separate and place the inflatable shaft from the paper tube to complete the inflation and deflation, and it does not need to separate any parts at the end of the shaft to tightly engage with the paper tube; The paper tube is placed simply: with the action of inflation and deflation, it can move and fix any position of the paper tube on the shaft surface.
NAB (miniature) air pressure through shaft brake miniaturizes NAB (standard type), saving resources and space. The micro air brake absorbs all the advantages of the standard air clutch, and then further reduces the weight and size. It is a necessary product for all mechanical miniaturization design.
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.
The slip shaft enables the slitter to be designed into automatic roll unloading, user-friendly operation, greatly improving the slitting and winding accuracy, running speed, and production efficiency. The slip shaft can improve the yield and reduce costs. Precious materials (metal foil, lithium battery separator, lithium battery pole piece, photo paper, etc.) must be used; The slip shaft makes it easier to cut narrow coils.
The top roller with excellent performance should not only have excellent elasticity, vibration absorption, small compression deformation, excellent wear resistance, good anti-static property, moisture absorption and desorption, anti winding property, oil resistance, but also have stable and uniform hardness, strong spinning performance, ozone resistance, aging resistance and other characteristics.
The magnetic particle clutch and brake have the above characteristics, and are now widely used in the unwinding and winding tension control in papermaking, printing, plastic, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related coiling processing industries. In addition, the magnetic particle clutch can also be used for buffer starting, overload protection, speed regulation, etc. Magnetic powder brake is also often used for dynamometer loading and braking of transmission machinery
The power amplifier is used in combination with the closed-loop type tension control unit to amplify the output signal or such control unit, and to apply the power source to the excitation coil of clutch / brake.
The power amplifier is used in combination with the closed-loop type tension control unit to amplify the output signal or such control unit, and to apply the power source to the excitation coil of clutch / brake.
The air inflation shaft air bag has the function of balancing the force pressure, so that it can evenly distribute the pressure. It usually takes only about 2 seconds to complete the inflation and deflation process, and the steps to place the coil are very simple and practical, not dangerous.
It has the characteristics that the excitation current and the transmission torque are basically linear. It can transmit a certain torque when it is independent of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact and vibration, energy saving, etc.
Silicon rubber roller can be selected in white, black, green, red, yellow, translucent, blue, etc.
At the same time, it is resistant to ozone, oxygen, light, weather and other aging factors, has excellent insulation, good water resistance, no odor in natural state, no gas damage to human body, is not easy to react with solvents, and has the characteristics of oil resistance, acid and alkali resistance, and corrosion resistance.
Technical parameters of expansion hose:
Sealing hole directly 30-120mm (can be processed according to user requirements)
Working pressure 1-8MPa (can be processed according to user requirements)
Starting pressure of safety valve 0.4-0.5MPa
Working flow: 4-4.5 tons of water can be injected per hour
Sealing depth 1-8m
Hose expansion coefficient 60%
The air expansion shaft is driven by high pressure gas. It controls the surface bulged shaft by inflating and deflating air to achieve the control of the surface expansion and tension of the shaft. The air expansion shaft is used in the special reeling and unwinding equipment to facilitate loading and unloading, save time and improve work efficiency. Also called air pressure shaft, expansion shaft, inflation shaft, inflation roll, inflation shaft, pressure shaft, inflation roll, etc.
