Description

Granular machines for processing flat-plate printing plates are known, made in the form of a suspension frame, for example, on four cables with a device for fixing the plate, as well as upper and lower bins for granular balls.

The described machine differs from the known ones in that the plate mounting device is made in the form of two elastic bars rotated around horizontal axes with the help of a handle with locks, one of the bars being mounted on a movable carriage moved from the flywheel by an endless chain.

Cables attached to the front of the frame are rigidly connected to. pistons of cylinders connected by pipelines with a hydraulic pump, and the lower and upper bunkers are connected by a pipeline connected to the water supply network.

These distinctive features of the machine allow to improve the quality of granulation and reduce noise when the machine is running.

FIG. 1 shows the general view of the machine; in fig. 2 - frame, plan view; in fig. 3 - device for inclining the frame.

The vortex machine is a skeleton / suspended from two front cables 2 and two rear cables 3. The frame includes a device for fastening the plate plate, which consists of two elastic bars 4 and 5 that can be turned with help; and the handle 6 with clamps 7 around the horizontal axes 8 n 9. To fasten the plates of various sizes, the bar 5 with the axis 9 is made movable, shuffled along the frame / using the flywheel 10, sprockets // and endless chains 12. The frame is also provided with side elastic clamps 13.

To tilt the frame 1, the front cables 2 are rigidly connected by means of hooks} 4 to the pistons 15 hydraulic cylinders 16. The latter are connected by pipes 17 to the hydraulic pump 18 via a distribution valve 19. The hydraulic pump 18 is turned on by starting button 20, mounted 126502

a bath on the guides 21 of the upper receiving hopper 22. Castor oil was used as the fluid supplied by the pump to the hydraulic cylinders 16.

The lower hopper 23 is connected by a pipe 24 to a water supply network. At the junction, a crane 25 and an injector 26 are mounted. The lower bunker 23 is also connected by a pipeline 27 to an upper bunker 22, the perforated bottom 28 of which is folding. Under the hopper 22 mounted drain funnel 29, connected to the sewer network.

The operation of the granulating machine is carried out in the following order.

The prepared plate plate is secured in the frame (using elastic bars 4 and 5. The upper hopper 22 moves along the guides 2} to the frame zone /. The bottom of the 28 bunker is tilted; the balls in the hopper are poured onto the plate, after which the hopper 22 returns to its original position. After the granulation process, open the rear beam 5 and turn on the hydraulic pump 18 using the button 20; the distribution valve 19 is turned into a position in which the liquid from the hydraulic pump 18 enters the hydraulic cylinders 16 and lifts the pistons 15 with the leading edge of the frame, which has been passed to them by means of cables 2. The latter takes an inclined position, and the balls are poured through the funnel 30 into the lower bunker 23. The valve 25 is opened. Water flows from the water supply network to the injector 26, which washes the balls and lifts them through the pipeline 27 to the upper bunker 22. Water from the bunker 22 passes through perforated bottom 28 into the sewer network. At the same time, water from the water supply system enters a perforated tube fixed on the front edge of the frame / (not shown) and rinses the plate and the bottom of the frame, after which the granular plate is dredged.
