Description

one

A known pre-press dePstpn press for the manufacture of sheet wood-based materials of the plywood type contains a press chamber mounted on a station, sealed with end face and side seals, and also two parallelly arranged endless belts passing through this chamber feeding the pressed material into the working chamber. In such a press, significant leaks of the working fluid from the working chamber are observed.

In order to eliminate this drawback, the side seals are fixed on the outer sides of the tapes along the width of the chamber with the possibility of coupling into the lock by means of the slits Iirio iia bed frame at the entrance and exit of the working chamber on both sides of the tapes in the plane of their movement of two pairs of rollers.

FIG. 1 shows the proposed press, the longitudinal run; in fig. 2 shows sections along LA and BB in FIG. one.

On the frame (not shown in the figures) of the press, there are mounted drums that carry the upper and lower endless closed movable leites 1, whose working branches serve respectively the upper and lower plates of the press. The endless ribbons pass through the working chamber 2, which is a closed box, covering the branches

tapes with between them pressed material 3.

A working medium is fed into the chamber and the tubes. Elastic end 4 and side 5 seals are provided for sealing the chamber. The end seals have nipples 6 for supplying the working medium in order to adjust the contact pressure 1 and a tape depending on the thickness of the material to be pressed. Lateral angles are straightened on the outer sides of mites along the width of the chamber and can be locked in, for which at the entrance of the working chamber on both sides of the tapes p. the planes of their movement are mounted on a bed of a pair of rollers 7. A second pair of rollers S is installed on the outlet of the working chamber and prevents the opening of the seal. Inside the working chamber, the seals are held in a closed position by the pressure of the working medium, preventing it from reaching the compression material. The tapes with lateral seals have rounded edges in cross section, and the profile of the groove of the rollers has the shape corresponding to the shape of a closed lateral seal.

At a considerable length of the compressible material, supports 9 are provided inside the working chamber, which prevent the ribbons from sagging with the material enclosed between them.

The press works as follows.

Subject to be pressed, mate al podasts in the direction indicated in FIG. 1 arrow, and is fascinated by ribbons. The rollers 7 are connected to the locking of the incineration, in this form of tape with the material enclosed between them is pushed into the working chamber, where the material is pressed between the tape and the pressure of the working medium. After the rollers 8 are rolled, the tapes arrive at the second pair of cables and open the seals.

Subject matter

A continuous press for the manufacture of sheet wood-based materials such as plywood, containing an assembly-mounted pressure chamber, sealed with end seals and side seals, as well as two parallel-arranged endless tapes passing through this cadger, supplying press material to the working chamber, characterized in that , in order to increase the tightness of the working chamber, it is equipped with hingedly mounted on the inlet and outlet of the working chamber on both sides of the tapes in the iloskos of their displacement The rollers provide for the possibility of joining tank seals to the lock, made with the corresponding alignments and depressions and attached to the outer sides of the tapes along the width of the chamber.
