Abstract

This invention relates to the machining of the surface of a sheet of rubber, namely pieces of sheet rubber. The goal is to ensure work efficiency by treating the entire surface of the material. For this, the processing drum is provided with an unbalancing element, and the table is spring-loaded and adjustable with respect to the bed frame. The pneumatic pressure piston is spring-loaded relative to the frame. In operation, the rubber piece is advanced and simultaneously processed by an eccentric beat of the processing drum. 1 il.

Description

This invention relates to the machining of the surface of a sheet of rubber, namely pieces of sheet rubber.

The purpose of the invention is to ensure operational efficiency by treating the entire surface of the material.

The drawing shows the device, a general view.

The device comprises a frame I, a processing drum 2, a feed unit 3 consisting of a stationary driving roller 4, kinematically connected with the processing drum 2, and a movable pressure roller 5, a table 6 with a guide platform 7 and a pneumatic clamp 8. The processing drum 2 of the device provided with an unbalancing element 9, and the table 6 is equipped with spring-loaded springs 10 and supports II that are adjustable relative to the base 1, while the pneumatic-pressing piston 12 is spring-loaded with the spring 13 relative to the base.

The handwheel 14 is mounted for movement by rotating the movable pressure roller 5 by means of a bevel gear and a screw nut (not shown).

The device works as follows.

The end of the treated I5 rubber sheet is guided into the free gap between the rollers 4 and 5 and pressed by the roller 5 by rotating the spindle 14. The required clearance between the processing drum 2 and the table 6 is set by adjusting the supports .11 at its raised position with compressed air fed into the pneumatic pressure chamber eight.

In the future, the device is ready for processing pieces of sheet rubber of the desired thickness without adjusting the gap between the rollers. From the drive (not shown), the roller 4 and the processing drum 2 begin to rotate. Subsequently, a piece of rubber 15 being processed enters the processing zone B, the gap between the table 6 and the machining table

The turning drum 2, which is applied (glued) on its surface with an abrasive, treats the surface of the rubber sheet 15 along its entire length. In this case, at the first moment, the rollers 4 and 5 keep the heel of the rubber sheet 15 from being caught and ejected without processing. Later, when a piece of sheet rubber is placed on table 6, it moves only forward due to the eccentric movement (beat) of the processing drum 2 due to the unbalanced element 9 and oscillatory movements of the table 6, also arising from the beat of the drum 2 and mutually compensating springs 10 and 13 compression, as well as compressed air pressure on the piston 12 of the pneumatic clamp 8. Next, the pressure on the piece of sheet rubber is weakened and its surface is processed. The oscillation of the table 6 also contributes to the advancement of the sheet rubber forward, as well as enhancing the quality of processing by removing the slit during the oscillation of the table while simultaneously resisting the resistance of the processing drum 2 with the surface of the rubber sheet 15 being processed. handle sheet rubber required thickness with the removal of thin sections.
