Description
Technical field
The utility model relates to industrial cutting mechanics field, relates in particular to a kind of shaftless blowing rocking arm set.
Background technology
Realize by cutting machine for the bundling of the long coiled material of length such as film etc. at present, after the blowing unit feed, batch through winding unit the bundling work of completing again after a minute cut unit cuts into several parts.The blowing process of blowing unit is by handbarrow, stock roll to be transported to the scene, then through wearing axle, lifting, the step such as fixing is completed.
For larger stock roll, the stock roll that surpasses 1000mm such as diameter, and when wanting to higher bundling speed, will higher requirement be proposed to the rotating shaft of stock roll, when bundling speed reached 300 meters of per minutes, the vibration that the degree of eccentricity of rotating shaft produces made the bundling material production fold of pulling out on stock roll.Therefore can't reach the effect of high speed bundling, can only be controlled at 250 meters of per minutes to bundling speed.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of shaftless blowing rocking arm set to be provided, not affecting the quality of bundling to the flutter rate of stock roll when unreeling at a high speed.
The technical scheme that the utility model is taked is:
a kind of shaftless blowing rocking arm set, comprise machine frame at two sides, chucking device, it is characterized in that, described chucking device is arranged on a upset screw rodb base, described upset screw rodb base is rotatable to be fixed on machine frame at two sides, described chucking device comprises the first be installed head and second head that is installed, described two heads that are installed can be around its axis rotation, two coaxial screw mandrels are housed on described upset screw rodb base, described two heads that are installed coordinate respectively and are arranged on two rhizoid bars, two described two rhizoid bars of motor-driven are installed respectively at the two ends of described upset screw rodb base, arrange two and lift the material cylinder in the mechanism of both sides, described two rotatable being fixed on machine frame at two sides of cylinder body one end of lifting the material cylinder, described two rotatable being fixed on described upset screw rodb base of piston rod of lifting the material cylinder.
Further, described second head that is installed connects a propulsion source.
Further, at the centre portion of described upset screw rodb base, dust boot is installed.
Further, the rotation direction of described two rhizoid bars is opposite, and described two motor steerings are identical.
Further, the rotation direction of described two rhizoid bars is identical, and described two motor steerings are opposite.
The beneficial effect of the shaftless blowing rocking arm set of the utility model is:
The be installed mode of head chucking stock roll of bilateral reduces the degree of eccentricity of stock roll;
Stock roll is lifted the material cylinder and is realized convenient and swift blowing.
