In the description of the present invention, it should be understood that the terms "inside", "outside", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The utility model discloses a press from both sides tight structure for felt area feeder as shown in fig. 1-3, this structrual installation is as felt area feeder indispensable partly on current felt area feeder, installation cylinder block 1 on the crossbeam of felt area feeder, cylinder block below installation cylinder 2, the cylinder stroke is 5mm, the output of cylinder is connected with top board 4, process a plurality of screw holes at the top board, a plurality of screw hole arrangement modes can be rectangular array and arrange, also can be circular array equipartition, all connect one in every screw hole and compress tightly post 3, the preferred circular cone end holding screw of post that should compress tightly, the bottom surface of circular cone end is the sphere, the sphere design both can take the felt area to press tightly warp and be unlikely to take the puncture destruction with the felt again. The side surface of the cylinder is provided with an L-shaped lower pressing plate 5, the cylinder is connected with the vertical plate part of the L-shaped lower pressing plate, the transverse plate of the L-shaped lower pressing plate is positioned below the upper pressing plate 4, and the upper plane of the transverse plate is provided with a plurality of grooves matched with the compression columns. The arrangement form of the grooves corresponds to the arrangement form of the compression columns, if the compression columns are arranged in a rectangular shape, the grooves are vertical straight grooves, and a plurality of grooves are arranged in parallel; if the compaction columns are circularly and uniformly distributed, the grooves are circular grooves, and a plurality of grooves are also circularly and uniformly distributed.

The utility model discloses the post that compresses tightly of circular cone sphere in the top board installation, set up the recess at the holding down plate, felt itself is flexible, the circular cone sphere that compresses tightly the post after the cylinder pushes down impresses the felt in the recess, greatly increased the frictional force between clamp plate and the felt, lift when normal during operation the cylinder, the bottom that compresses tightly the post this moment apart from the distance of 3 millimeters on the felt upper surface, after material processing on the mesa finishes, the pay-off begins, the cylinder pushes down this moment, only need 0.35 MPa's pressure to compress tightly the felt this moment, pressure supply can be accomplished to conventional compressor, and need not open the pump all the time and inflate, press from both sides tight felt, the crossbeam antedisplacement.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.
