Description

  By taking a lump of rubber into a rubber sheet and evenly dusting (powdering) it onto the upper surface of the sheet, it prevents sticking of the overlapping rubber sheets and efficiently packs, transports, cuts and separates the next process. The present invention relates to a dusting device to be performed.

  Japanese Laid-Open Patent Publication No. 7-214639, which is known in the art, is a mechanism for controlling the amount of powder falling in the container by gravity between the container and the rotating body. Stable powder supply is not possible, and the clogging of the powder in the container and the uneven flow of the powder in the container are still used depending on the adjustment of the worker under the supervision of the worker.

  In order to drop the powder cut out from the powder cutting roll 23 in a uniform amount, it is uniform to break the powder into a container and make it uniform and to have the function of completely dropping the powder discharged by the powder cutting roll. Necessary for stable dusting.

  The unstable function using the natural falling of the conventional dusting device enables stable dropping and stable cutting, contributing to the improvement of the demolding work by uniform powdering and the production of high quality products.

  By making the work process an easy work that does not depend on skills, the supply work is simplified and the labor of the worker is reduced.

Means for trying to solve the invention

  As shown in FIG. 1, the powder density on the powder cutting roll 23 is made uniform by disintegrating the powder so that the powder in the container can be stably supplied to the powder cutting roll 23, and equipped with a rotating bar 21 and stirring. Put it in a state.

  As shown in FIG. 1, by adjusting the gap between the surface of the powder cutting roll 23 and the powder container 20, a powder gate 22 is provided to prevent the powder from falling down due to the nature of the powder, and the gap can be adjusted. To.

  A groove of 2 to 10 mm (determined according to the particle size of the powder) on the surface circumference of the powder cutting roll 33 so that the powdering amount can be easily adjusted by changing the speed of the electric motor. A fixed amount of continuous discharge by rotation is performed.

  As shown in FIG. 1, when powdering work is performed, powder is scattered around the apparatus and the environment is deteriorated. Therefore, the environment is prevented from being deteriorated due to the scattering of the powder by being stored in the case of the internal dust collection.

Effect of the invention

  Equipped with the powder breaker rotation bar 31, the powder 36 on the powder cutting roll 33 can be maintained in a state where the powder density is applied with high precision over the entire width of the powder cutting roll 33, and stable supply can be achieved. The shape of the bar of the dust breaker rotation bar 31 is selected in accordance with the properties of the powder to realize continuous and stable supply. (FIG. 4A is a flat bar B is a square bar C is a round bar)

  By providing the powder gate 32, the dripping from the gap between the powder container 14 and the surface of the previous powder discharge roll 22 depending on the type of the powder 26 is adjusted by adjusting the particle size of the powder 36, so that the powder is replenished. I was able to prevent drowning.

  As shown in FIG. 1, it is possible to adjust the discharge amount of the powder 36 by the uniform volume in the groove of 2 to 10 mm on the circumference and the increase / decrease of the rotation speed on the surface of the powder cutting roll 33. done.

  After carrying out the powder cutting roll 33, a stable discharge amount could be maintained by completely removing the adhered powder by the powder dropping brush roll 34.

As shown in FIG. 1, the powder having a high specific gravity is collected and collected in the collection tank 18, and the others are sucked into the dust collector, resulting in a good working environment with no powder scattering.
By supplying an even amount of powder, it was possible to save excess powder without applying excessive powder, and to reduce powder and operation costs even during recovery.

As shown in Fig. 1 and Fig. 2, this is an example of equipment for powdering only the top surface and powdering the top and bottom surfaces. In FIG. 1, the powder cut out from the powder cutting machine 14 is rubbed with the rotary brush 15 on the upper surface of the rubber sheet 11 conveyed from right to left, and unnecessary powder is scattered and dropped to the lower part of the roller.
In Fig. 2, it is conveyed from the right, passed through the lower part after top surface dusting, and conveyed from left to right.

  The content described in [0010] and [0011] could be smoothly continued by setting the powder breaker rotating bar and the dust falling brush roll to a speed of about 150% with respect to the surface peripheral speed of the rotating feed roll.

Japanese Patent Laid- Open No. 7-214638 , in which powder in a container is wound up by a rotating roller and powder mixed with air is attached, and the amount of attachment of the rotating body varies greatly depending on the season and is unstable. and in possible mechanism, it can not supply continuous stable powder considering the fluidity of the powder, yet the operator of the operator to flow like unequal powder in clogging or containers powder in the container under surveillance Used depending on the adjustment.

In order to drop the powder cut out from the powder cutting roll 33 in a uniform amount, the powder in the powder container 14 is broken and equalized, and the powder discharged from the powder cutting roll 33 has a function of dropping completely. Is necessary for uniform and stable dusting.

As described in FIG. 1, the powder density on the powder cut roll 33 in that the powder in the container is stirred equipped with powder loosened powder break rotating bar 31 so that it can be stably supplied to the powder cut roll 33 To a uniform state.

As shown in FIG. 1, by adjusting the gap between the surface of the powder cutting roll 33 and the powder container 14 , a powder gate 32 is provided to prevent the powder from falling through the gap due to the properties of the powder, and the gap can be adjusted. To.

By providing the powder gate 32, the dripping from the gap between the powder container 14 depending on the type of the powder 36 and the surface of the previous powder cutting roll 33 is adjusted to match the particle size of the powder 36 so that the powder 36 can be repelled by impact at the time of powder replenishment. I was able to prevent it.
