Definitions
- the invention relates to a pressing device for a double belt press according to the preamble of claim 1.
- Such pressing devices are used for double belt presses, in particular in the production and / or coating of single or multilayer webs of different materials.
- the double-belt presses have a circulating upper press belt and a circulating lower press belt, between which the material to be pressed is taken up, conveyed in the conveying direction and in this case pressed and then output.
- the compression takes place between the lower run of the upper and the upper run of the lower press belt by a contact pressure device, which bears slidably against the steel belts and compresses them with a predetermined pressure.
- the pressing device in this case has pressurizable, temperature-controlled heating plates, on which a plurality of adjacent in the transport direction pad inserts are added, each pad insert has a support plate and a slide made of, for example, plastic.
- the supply of the lubricant is generally under pressure, wherein the lubricant can distribute over the feed holes and formed on the sliding surfaces grooves in the transverse direction over the entire pressing surface or sliding surface and the material thereby experiences relatively uniform pressing conditions.
- the discharge of the lubricant takes place on the one hand via the Ab technologicalbohronne, which extend in accordance with the Zu Industriesbohronne, and on the other via lateral edges of the sliding surfaces or pressing surfaces. The discharged lubricant is returned to the lubricant circuit.
- the lubricant - generally oil - between the sliding surface and the steel strip Due to the even distribution of the lubricant - generally oil - between the sliding surface and the steel strip, direct contact between these components can be largely avoided, so that a low coefficient of friction and low wear is achieved.
- a uniform distribution is important here in order to obtain a uniform pressure and a uniform temperature during the transport of the material between the pressing surfaces and thus a homogeneous starting material.
- the pressing pressure of the lubricant is in the immediate vicinity of the atmospheric pressure of the surrounding atmosphere and of the laterally emerging lubricant. Accordingly, it is difficult to maintain the uniform pressure in the lubricant even in the lateral edge portions.
- EP 0 491 972 A1 shows a pressing device for a double-belt press, in which transversely extending grooves are formed in the sliding surface of the sliding lining in order to swirl the sliding medium, in particular in the outer regions.
- the uniformity achievable thereby is not sufficient in the processing of certain materials, so that the use of such presses limited and their efficiency is significantly impaired, and in particular materials that require a uniform compression across their transverse extent, therefore, are generally processed in other pressing devices which do not allow continuous feeding and compression.
- DE 197 30 152 A1 shows a double-belt press of the type mentioned in the opening paragraph.
- different grooves and blind grooves are formed in the sliding surfaces, wherein grooves formed in main areas are arranged in feed channels. and slip-off passages for the lubricant pass, grooves formed in outer areas for swirling, for pressure reduction and for collecting laterally emerging from a pressing region lubricant, and are formed in arranged between the main areas and outer areas transition areas blind grooves.
- DE 44 14 957 C2 shows a double belt press with a pressing device, in the sliding lining grooves are asbilet, wherein some of the grooves lubricant is supplied, which forms a sliding film on the sliding coating, and is discharged via other grooves of this lubricant again.
- US 2 909 804 discloses a press machine for a double belt press, in which an upper and a lower steel strip are first guided between rollers for pressing a molding compound and subsequently guided between a row of upper plates and lower plates.
- the lower plates have cavities and upwardly leading openings, with steam and compressed air being introduced into the cavities, which flow up through the openings against the lower metal strip.
- the upper plates have upper portions and lower portions sealed to them, with compressed air and steam being added between the portions and pressing against the upper steel band through openings in the lower portions.
- GB 2 091 165 A shows a pressing device for the manufacture or coating of boards of wood fibers, wood chips or the like, in which the material to be pressed is pressed between an upper, endlessly circulating steel strip and a lower, endlessly circulating steel strip.
- a suitable sealing of the steel bands is provided.
- the invention has for its object to provide over conventional pressing devices for double belt presses improvements and in particular to provide a pressing device for a double-belt press and a double-belt press with such a pressing device, which allow uniform contact pressure conditions, in particular over their transverse extent, with continuous material supply. This should advantageously be possible with relatively little effort, in particular low additional expenditure on equipment.
- the invention is based on the finding that irregularities in the lubricant flow on the sliding surfaces are essentially caused by lubricant leakage currents between the pressure-transmitting elements.
- lubricant leakage currents between the pressure-transmitting elements.
- a non-negligible proportion of the lubricant between the heating plate and carrier plate and carrier plate and sliding linings and flows between the sliding linings resulting in irregularities of the pressure distribution and pressure medium supply and - discharge on the sliding surfaces.
- Such leaks occur in particular due to the different thermal expansion coefficients of Plastic material of the sliding linings and the metal parts and the high temperature differences between idle state and various operating conditions.
- both additional seals and grooves may be provided in the surfaces of the components in the respective spaces. Additional sealing elements block or hinder this directly a leakage of the lubricant through the gap in question.
- the grooves or surface profiles increase the flow resistance in particular by local turbulence; Furthermore, a lateral discharge of the lubricant can be achieved at the relevant points.
- lubricant can flow between the individual sliding linings and form, for example, a flow between the sliding linings and the carrier plate or between the carrier plate and the heating plate.
- Local turbulences which lead to a significant increase in the flow resistance, can be achieved in particular by a plurality of grooves or Verwirbelungsnuten arranged on a two-dimensional surface whose groove start and groove end lie on the relevant surface.
- a corresponding seal in particular over the entire width of the respective surface extending grooves and annular grooves may be provided, wherein in the transverse grooves and grooves a corresponding seal can be used.
- Leakage of lubricants between the sliding liners may be at least compromised by a suitable tongue and groove engagement between two adjacent sliding liners.
- On the front or top of the heating plate provided strips for receiving the carrier plate and sliding coating existing lining inserts can at least in places - for example in lateral strip areas - are formed by sealing elements of, for example, plastic or other elastic material.
- According to the invention can also be advantageously conducted atmospheric pressure between the support plate and the sliding coating by z. B. in one, several or all carrier plates as flow resistance increasing means extending from the side transverse grooves on the underside of the carrier plates and pass in vertical holes through the carrier plates.
- the atmospheric pressure effectively affects the lubricant flow in this area;
- a dimensioning of the compound is such that an oil passage is thereby low. If necessary, leaking oil can be collected.
- the flow of the lubricant and the lubricant conditions on the sliding surface can be smoothed out in a surprisingly simple manner by preventing or impairing lubricant leaks and a lubricant flow below the sliding surface, thereby achieving uniform environmental conditions during the pressing operation.
- a high uniformity of the pressing conditions is achieved in particular in lateral marginal areas, a uniform processing of the input materials can be achieved and the possibility of using the cost-effective double belt presses with continuous feed to be extended to additional materials.
- Exchanging the friction linings subject to wear can be achieved in a simple manner by a positive reception, in particular a dovetail guide of the sliding linings on the support plates.
- the dovetail guide is in this case formed at one end by a corresponding Schugreifung the support plate and another, for example, rear or front end, by a end strip with a corresponding Schugreifung, the end strip is fixed to the support bar, for example by a screw connection.
