SU100154A1 - Paint registration mechanism - Google Patents

Description

The invention relates to devices used, for example, in fabric printing or back-printing machines for registering paints by displacing the form cylinder relative to the leading gear.

In the su: 1 procession of cich machines, the registering of paints (“weaving”) is carried out by a mechanism that is polished in) 5Ide fortified-south on the screw gear of the screw, interacting with the worm gear rigidly connected to the plate cylinder. Worm scattering is done by the worker manually.

In the proposed device, in order to increase safety and convenience of operation, a second worm gear is used to rotate the screw, the movement of which is communicated by means of a differential gear mechanism.

FIG. Figure 1 shows a schematic diagram of the paint register mechanism (the position of the friction wheels is shown conventionally); in fig. 2 is a section along AA in FIG. one; in fig. 3 - view of the mechanism from the side of the plate cylinder.

On the spindle of the plate cylinder / fixed on the key an elongated sleeve 2, is fastened securely with a worm gear 3. On the sleeve there is a loose gear 4 that carries a worm to 5, which interacts with a worm gear 3. At one end, the worm 5 is fixed a friend of the worm gear 6, interacting with the screw 7. Last fit on one shaft with a planetary wheel 8 coupled with a parasitic pair of gears 9. The driver of gear wheels 8 VI 9 is served by a gear 4. The central gear 10 differential toothed fur the bottom is freely seated on the hub 2. The wheel is paired with the end clutch. The undercut between the clutch and the wheel 10 includes a flywheel shoulder 12. The latter is equipped with a disk 13 mounted on compression springs 14.

In order to displace the plate cylinder relative to the reporting gear and thereby implement the paint register, the worker presses the disk 13. At the same time, the end clutch // slows down the central wheel 10. The planetary wheels begin to run in the central wheel, turning the worm to 7. Afterwards through the wheel 6 and a red heart 3,

5, moves the plate cylinder 1 relative to the report of gear. One or another direction of displacement is achieved by alternating coupling of the central wheel 10 to the planetary wheels 8 or 9. The wheel 10 can be moved along the hub 2 using the flywheel 12 (the extreme right position of the flywheel is shown in fig. 1). At the end of the registration, the pressure on the disk 13 is stopped. At the same time, under the action of the springs 14, the frontal L-coupling L opens, and the movement of the planetary wheels around its own axes is transformed.

Subject invention

Paint registration mechanism, for example, for fabric printing machines,

consisting of a screw nesterni rigidly fastened to the cylinder and a leading shear chain connected by a screw that can rotate in both directions, changing the position of the worm gear relative to the report gear while the machine is running, characterized in that it can increase safety and convenience of operation, for rotation of the worm, a second gearwheel was used, the movement of which is communicated from one of the two planetary gear wheels, alternately meshed with the central wheel and running around this wheel, if the latter It is braked with the help of a face friction clutch, and the report gear serves as a carrier for the hoses.
