Abstract
The invention discloses a pneumatic core shaft gas-filling device of a sleeve type flexo printing machine, comprising a motor bracket, wherein one end of the motor bracket is fixedly connected with a shell of a servo motor; the other end of the motor bracket is fixedly connected with a frame; a gas inlet is formed in the motor bracket in the radial direction; the radial direction of the gas inlet is aligned with a gas-filling mouth on a printing roller pneumatic core shaft; two groups of seal rings are installed on the contact face between the internal circular surface of the motor bracket and the external circular surface of the printing roller pneumatic core shaft; and the seal rings are distributed on two sides of each of the gas inlet and the gas-filling mouth. With the adoption of the device disclosed by the invention, the printing roller pneumatic core shaft can be driven by the servo motor to freely rotate, and the alignment of the radial direction with the gas-filling mouth is unnecessary, so that the filled-gas leakage problem caused by the alignment error of the gas-filling mouth is thoroughly solved; and therefore, the axial direction and the peripheral direction of the printing roller pneumatic core shaft unnecessarily return to zero positions during the gas filling.
Description
Technical field
The invention belongs to the printing machine equipment technical field, relate to a kind of telescopic flexible printing machine inflatable mandrel aerating device.
Background technology
The maximum difference of telescopic flexible printing machine and common flexible printing machine is that telescopic flexible printing machine has adopted version to roll and the anilox roll sleeve technology, is one of key mechanism of telescopic flexible printing machine, is to realize the flexibly key mechanism of plug of version roll sleeve cylinder.Adopt the largest benefit of this technology to be that version is rolled, anilox roll exchanging is convenient, be provided with one deck elastic layer at sleeve lining, can small swell under gas pressure, roll as example with version, version roll sleeve cylinder inwall elastic layer swell when the inflatable mandrel is ventilated can realize flexible plug; The sleeve lining elastic layer shrinks when dying, and sleeve can be held tightly on mandrel.
Existing version is rolled mandrel and is inflated structure, sees Fig. 1, in inflatable mandrel side charging connector being set, with the rotation of servomotor band moving mandrel, charging connector is aimed at charging connector, and charging connector rises to mandrel and inflates.Such structure, when inflating at every turn, version roll the inflatable mandrel to and circumferentially all must return zero, make charging connector aim at charging connector, but usually because a variety of causes is aimed at small error arranged, cause the problem that leaks air when inflating for the inflatable mandrel.
Summary of the invention
The purpose of this invention is to provide a kind of telescopic flexible printing machine inflatable mandrel aerating device, it is unreasonable to have solved in the prior art structural design, and the valve alignment error is large, the problem of gas leakage when causing inflating.
The technical solution used in the present invention is, a kind of telescopic flexible printing machine inflatable mandrel aerating device, comprise an electric machine support, electric machine support one end is fixedly connected with the shell of servomotor, the electric machine support other end is fixedly connected with frame, on electric machine support, radially have an air inlet, air inlet radially rolls charging connector on the inflatable mandrel to legal copy, the contact-making surface place of rolling inflatable mandrel outer round surface in electric machine support internal circular surfaces and version is equipped with two groups of sealing rings, and two groups of sealing rings are distributed in air inlet and charging connector both sides.
The invention has the beneficial effects as follows, at electric machine support air admission hole is set, and sealing ring is installed in the air admission hole both sides, version is rolled inflatable mandrel charging connector to be placed between two sealings, this example edition rolls the inflatable mandrel and can rotate freely under servomotor drives, can directly inflate by the enterprising pore of electric machine support when rolling the inflation of inflatable mandrel for version, and needn't radially align again charging connector, thereby thoroughly solved the inflation gas leakage problem that the charging connector alignment error causes, no longer needed version to roll the inflatable mandrel when making inflation and circumferentially all get back to zero-bit to reaching.
Description of drawings
Fig. 1 is the existing inflatable mandrel inflation mechanism structural scheme of mechanism that rolls.
Fig. 2 is the structural representation of telescopic flexible printing machine inflatable mandrel aerating device of the present invention;
Fig. 3 is the local enlarged diagram among Fig. 2;
Among the figure, 1. servomotor, 2. electric machine support 3. edition rolls inflatable mandrel, 4. sealing ring, 5. edition roll sleeve cylinder, 6. air admission hole, 7. charging connector, 8. frame.
The specific embodiment
With reference to Fig. 1, the structure that existing version is rolled inflatable mandrel aerating device is, version on the frame 8 is rolled inflatable mandrel 3 and servomotor 1(and subsidiary reductor thereof) the coaxial connection, version is rolled and is set with an edition roll sleeve cylinder 5 on the inflatable mandrel 3, rolls inflatable mandrel 3(towards servomotor 1 one ends in version) radially (side) be provided with charging connector 7.During inflation, the gas-charging connection of below moves up, and version is rolled inflatable mandrel 3 and must be aligned by radial rotating, could realize inflating.
With reference to Fig. 2; Fig. 3; the structure of telescopic flexible printing machine inflatable mandrel aerating device of the present invention is; comprise an electric machine support 2; electric machine support 2 one ends are fixedly connected with the shell of servomotor 1; electric machine support 2 other ends are fixedly connected with frame 8; on electric machine support 2, radially have an air inlet 6; air inlet 6 radially rolls charging connector 7 on the inflatable mandrel 3 to legal copy; the contact-making surface place of rolling inflatable mandrel 3 outer round surface in electric machine support 2 internal circular surfaces and version is equipped with two groups of sealing rings 4; two groups of sealing rings 4 are distributed in air inlet 6 and charging connector 7 both sides; so that the cavity between two sealing rings 4 consists of the gas-filled protective passage of air inlet 6 and charging connector 7, the sealing when realizing air inlet 6 to charging connector 7 inflation.
With reference to Fig. 3, electric machine support 2 is inner circle step circular ring structure, and the thin wall circular at two ends is respectively arranged with flange and connects dish, is respectively applied to be fixedly connected with shell, the frame 8 of servomotor 1; The inner circle step surface of middle inner chamber rolls inflatable mandrel 3 outer round surface with the version at charging connector 7 places and contacts by two groups of sealing ring 4 slipper seals.
During telescopic flexible printing machine inflatable mandrel aerating device work of the present invention, version is rolled inflatable mandrel 3 rotation under servomotor 1 power transmission shaft drives, but no matter version is rolled inflatable mandrel 3 how to rotate, charging connector 7 always can be by the airtight cavity of formation and air inlet 6 UNICOMs on the electric machine support 2 between two sealing rings 4, therefore can when version is rolled inflatable mandrel 3 and is in arbitrary phase, roll the inflation of inflatable mandrel 3 inner chambers to version, thereby fundamentally solve the inflation gas leakage problem that the valve alignment error causes.
