Abstract

The utility model discloses an EPS foam plate appliance, in particular to an EPS plate molding machine. The utility model comprises a mold cavity; the periphery thereof consists of a hollow cavity steam chamber, vent holes provided on cavity boards of the steam chamber and the mold cavity, a movable base mold with the vent holes, a steam inlet of each steam chamber and a steam outlet of each steam chamber. Separating boards are provided in four vertical steam chambers of the mold cavity, and a through pipeline with a valve is provided between a main steam chamber and a sub steam chamber which are formed on the two sides of the separating board. The vent hole is provided within a distance on the upper part of the cavity board of the sub steam chamber. With the sub steam chamber additionally provided in the utility model, foam particles in the mold cavity can fully contact steam and evenly be heated when the plate in big size is manufactured; furthermore, a non-resistance passage of the steam can not be formed and hence the waste of the steam is avoided. The quality evenness, combination and hand feeling of the plate in big size manufactured by the EPS plate molding machine in the utility model is remarkably better than the quality evenness, combination and hand feeling of the products manufactured by the prior model.

Description

The EPS sheet-forming machine

Technical field

The utility model relates to a kind of plant equipment of processing eps foam sheet material, refers in particular to a kind of make-up machine of EPS sheet material.

Background technology

At the eps foam plastic industry, the EPS sheet-forming machine is the plant equipment that the eps foam particle is processed into foam board.It is that the eps foam particle is put in the die cavity of a moulding, and the steam that feeds certain hour then coheres the eps foam particle and is integral, and forms the section bar of certain size.Its die cavity is made up of six faces, and each face all is the interlayer of hollow, and the interlayer of this hollow is a steam chest.All be provided with passage on the chamber plate of the side that each steam chest and die cavity are adjacent, the arranged outside of each steam chest has air intake or venthole.Steam enters from the steam chest of certain several times, and discharges from other steam chest.In order to go out the sheet material of different size with a device fabrication, all be provided with movable bed die in the die cavity inside of sheet-forming machine, be used for adjusting die cavity inner height size, thereby can mould board product with the bubble of a device fabrication different size.Also be provided with passage on the movable counterdie; But in the activity interval of the bottom of four of die cavity vertical chamber plates, movable counterdie is that passage is not set, because when the position that movable counterdie rises is higher, if below the movable counterdie passage is arranged, can form unresisted passage with the exhaust hole of exhaust hood, steam can directly be discharged, and no longer enters die cavity eps foam is heated.Not only can not produce qualified product, and can cause a large amount of losses of steam, form serious waste.And when producing large-sized goods, movable bed die need be dropped to bottom near die cavity, this moment, the eps foam particle of bottom just can not be added thermal break-through fully, thereby bonding strength is herein reduced, and goods can not be guaranteed on quality.

Summary of the invention

It is that energy savings has the EPS sheet-forming machine that can guarantee the EPS board quality that the utility model technical issues that need to address provide a kind of.

The utility model is achieved in that

Its main body is a die cavity, the steam chest that six faces of die cavity all are made up of cavity, chamber plate between each steam chest and the die cavity is provided with passage, is provided with the movable bed die of band passage in die cavity, all is provided with air intake or steam drain in the outside of each steam chest; In four vertical steam chests around the die cavity dividing plate is set respectively also, these dividing plates are divided into major and minor two steam chests to four steam chests respectively, are communicated with the pipeline of band valve between main steam chest and secondary steam chest.In a segment distance on the top of secondary steam chest chamber plate, be provided with passage, when movable bed die rises near the passage of secondary steam chest,, make and no longer advance steam in the secondary steam chest valve closing; If the position of movable bed die is lower than the passage of secondary steam chest, then when heating, open valve and make steam also enter secondary steam chest, the passage by secondary steam chest enters die cavity again, thereby the eps foam particle of die cavity bottom also can fully be heated.

Further improvement of the utility model is: the passage section of secondary steam chest and the ratio of not establishing the length of passage section are between 1/2 to 2/1.

Further improvement of the utility model is: on the lowering or hoisting gear of movable bed die, add link to each other with control system, can real-time tracking the residing position coder of movable bed die; Control system is connected with valve, and control system can open or close valve automatically according to the residing position of movable bed die.

The technological progress that the utility model is obtained is:

Because the utility model has increased a secondary steam chest, when producing large-sized sheet material, movable bed die drops to the bottom near die cavity, this moment main steam chest is led to the valve open of secondary steam chest, major and minor steam chest communicates and forms the steam chest of a connection, steam leads in the die cavity through the passage of major and minor steam chest respectively, and the eps foam of the bottom of large-sized sheet material is also fully heated; Need when producing undersized sheet material the lifting that make progress of movable bed die, can lead to main steam chest the valve closing of secondary steam chest this moment, steam do not arranged in the secondary steam chest, and steam leads in the die cavity from main steam chest.After entering steam all foam beads in penetrating die cavity of die cavity, a part is discharged through the passage and the steam drain on die cavity top, a part through the passage on the movable bed die enter lower floor die cavity, discharging by the steam chest of die cavity bottom.So no matter to be to produce undersized sheet material or produce large-sized sheet material, die cavity inner foam particle can both fully contact with steam, obtains uniform heating; And can not form the non-resistance passage of steam, cause the waste of steam.Adopt quality uniformity, associativity, the feel of the large size plate that EPS sheet-forming machine of the present utility model produces obviously to be better than the goods that existing type is produced.

The passage section of secondary steam chest is to be a proper ratio between 1/2 to 2/1 with the ratio of not establishing the distance of passage section, and the particle bottom it promptly can guarantee can be penetrated fully by steam, does not stay the dead angle, can save steam to greatest extent again.

Whether the valve that links to each other with control system that the utility model is provided with and the encoder of tracking activity bed die position can realize in the secondary steam chest the automatic control with steam, the automation that helps producing.
