Description

The peculiarity of the described machine for grinding porcelain round products is the use of two oppositely moving with different speeds of endless elastic bands, set at an angle to each other and intended to impart simultaneous rotational and translational motion to the workpiece with respect to abrasive tiles, resulting in their longitudinal high-frequency vibrations . This embodiment of the device allows relatively simple means to automate the grinding of the lower annular protrusion of porcelain round products.

FIG. 1 shows the described machine, top view; in fig. 2 is a section along AA in FIG. one; in fig. 3 is a section through BB in FIG. one; in fig. 4 is a section along the explosive in FIG. one.

A workpiece located on a horizontally vibrating table / lined with abrasive tiles 2 is simultaneously rotated and translated in motion.

The product is pressed into the abrasive by two moving in opposite directions with different speeds endless elastic, for example rubber, ribbons 3, arranged at an angle to each other.

The abrasive tiles 2 are attached to the table / in the order of decreasing the size of the abrasive grain.

Water is supplied to the abrasives through a medium of two pipes 4 provided with openings and is discharged into the sewage system through a receiving funnel at the beginning of the table.

The amount of force applied to the abrasive is controlled by changing the angle of inclination of the endless belts to the abrasive table, and the direction of the angle of inclination of each belt depends on the direction of its movement.

The difference in speeds of moving in opposite directions to the endless ribbons provides the translational movement of the rotating product over the abrasive. The greater this difference, the higher the rate of translational movement of the workpiece.

In order to intensify the grinding process, longitudinal high-frequency vibration is attached to the abrasive table with an ultrasonic, electromechanical or some other vibrator 5.

For processing the plates and saucers of different diameters and heights, the abrasive table is made elevating or is changed by an appropriate amount to the angle of inclination between the endless belts.

The automatic feeding of products into the grinding unit can be carried out in different ways. For example, a product mounted on an inclined tray 6 is fed to the abrasive table / by the action of its own weight, where it is caught by the ribbons 3.

The processed product slides down an inclined plane 7 on

belt conveyor or other device that is transferred for further processing.

Subject invention

A machine for grinding porcelain round products, characterized by the use of two, moving in the opposite direction with different speeds, endless elastic bands, installed at an angle to each other, designed to communicate simultaneous rotational and translational motion of the workpiece to relatively abrasive tiles that receive longitudinal high-frequency vibrations, for the purpose of processing the lower annular protrusion (leg) of porcelain, round-shaped articles (plates, saucers, etc.).
