Definitions
- the present invention relates to continuous presses for the manufacture of sheets by pressing of a corresponding material, in particular wood-based panels or laminate panels.
- the present invention relates to an improvement on the rolling plates used in such continuous presses.
- Continuous presses are used for the production of boards such as wood board, laminate board, chipboard, fiberboard and the like.
- the inserted material to be compacted is pressed continuously between a press upper part and a press lower part by means of an upper steel press belt and a lower pressed steel press belt.
- the steel press belts run endlessly around deflection and drive rollers.
- the steel strips in the pressing area are supported on rolling plates with the interposition of rolling bodies.
- the rolling elements may, for example, be rod bearings, as described, for example, in DE 31 17 778 C2.
- These rolling plates normally have heating channels with which the material to be pressed is heated.
- a heat transfer element is passed through the heating channels, such as a heat transfer oil, hot water or steam, which can be provided by a heating system arranged outside of the rolling plate.
- a pressure is exerted on the rolling plates, which is passed on to the pressed material via the rolling elements and the pressed steel strip.
- an arrangement of press cylinders is used for this purpose.
- the present invention therefore has the object to improve the known continuous presses with simple means such that oil residues do not damage the insulation and that the risk of fire is reduced.
- the continuous press for making sheets by pressing a corresponding material comprises upper and lower continuous steel sheet press belts which are supported by rolling bodies on upper and lower rolling plates.
- the lower unrolling plate in the vicinity of at least one lateral edge on means which forces a dripping of on the outside of the lower Abrollplatte along running liquid.
- liquids such as used oil are prevented from running from the upper rolling plate, the rolling elements and the steel press belts to the lower rolling plate and then collecting there, for example together with other residues.
- the means according to the invention ensures that the liquid running along the outside of the lower rolling plate drips off, in the vicinity of the lateral edge of the lower rolling plate. The dripping liquid at this point can then be collected, for example, in appropriate containers or channels and transported out of the continuous press.
- the means is arranged in the vicinity of both lateral edges of the lower rolling plate. This will ensure that no liquid collects from beneath the bottom plate from both sides.
- the means can basically be arranged at two points of the lower rolling plate. One spot is the outside of the lower rolling plate. The other place is the bottom of the lower roll plate. In this case, the agent can either be attached to the lower Abrollplatte or be part of the lower Abrollplatte.
- the means has a nearly vertical section which forces the liquid to drip off.
- This almost vertical right section is formed in one embodiment by machining, eg milling a groove in the bottom of the lower roll plate.
- Fig. 1 is a sketch of the structure of a continuous press as may be used in the present invention
- Fig. 2 is a plan view and a side view of a lower rolling plate according to the present invention.
- FIG 3 shows a section of a lower rolling plate according to the present invention.
- Figure 1 shows in outline the construction of a continuous press 1, as it can be used in connection with the present invention.
- the press 1 contains a press upper part and a press lower part, in each of which there is a circulating steel press belt 2, which is guided by means of corresponding deflection rollers.
- the two steel press belts 2 in a pressing area form a gap in which the pressed material is pressed.
- rolling elements 3 are arranged on the back of the steel strips.
- these are steel rods that are guided by means of a chain or another suitable rod circulating device via a circulation path (not shown).
- the press upper part and the press lower part also have an upper rolling plate 4 and a lower rolling plate 5.
- These rolling plates 4, 5 are
- Heating channels with which the material to be pressed can be heated.
- the rolling plates 4, 5 also exert pressure on the pressed material via the rolling elements 3 and the steel sheet strips 2.
- FIG. 2a shows a plan view and FIG. 2b shows a side view of the lower rolling plate 5 according to the present invention.
- the top view in Figure 2a shows the bottom 8 of the lower Abrollplatte 5.
- Right and left in the picture the side edges of the lower Abrollplatte 5 can be seen.
- a groove is indicated along the lateral edge, which in this embodiment forms the means 6 which forces a dripping of the liquid.
- FIG. 2b shows a side view of the lower rolling plate 5.
- the means 6 according to the invention, for example on the outside 7 or on the underside 8 of the lower rolling plate 5.
- the means 6 is arranged on the underside 8. It is, as in Figure 2a, a gutter, which is arranged along the lateral edge of the lower rolling plate 5.
- FIG. 3 shows the section of the lower rolling plate 5 indicated by a circle in FIG. 2b.
- the channel used as means 5 the almost vertical section 9 is shown, which can be used within the scope of the invention in order to force the liquid to drip off.
- a continuous press is provided by the present invention for the first time, is prevented by simple means that oil residues, the insulation on the bottom of the lower roll plate are damaged and in which the risk of fire is reduced.
