Abstract
The uninterrupted net replacer for screw extruder in plastic board producing line is used for rubber and plastic material filtering. It includes one hydraulic station, one net replacer and connecting pipeline. The net replacer includes an oil cylinder, a net replacing board, a connector and a rack, and the net replacing board has two, one upper and one lower, net holes and filter net inside the holes, and is set in the pipeline. During the production, the filter net may be replaced through converting the state of the net replacer with the hydraulic system conveniently and effectively without need of stopping the screw extruder.
Description
Technical field:
The present invention relates to a kind of XPS extrusion moulding type warming plate apparatus for production line.Be specifically related to a kind of uninterrupted net replacer for screw extruder in plastic board producing line.Be used for the charging of high molecular plastics and rubber glue and filter operation.Belong to the forming machine technical field.
Background technology:
XPS extrusion moulding type warming plate production line is that the rubber and plastic glue material is made one of main forming machine of various templates.Rubber-plastics material stirs and adopts spiral the mixing up and down to stir, and will heat rubber and plastic glue melt again and be pushed through the special-purpose runner of mould by screw rod, by the control to hot melt rheology behavior, makes different size model warming plate section bar.Therebetween in feed process, impurity in the rubber and plastic glue melt must be cleaned out, net-changing device is used for clearing up impurity exactly, to guarantee the inherent quality of heat preservation plate material, guarantee that its quality meets standard-required, comprise physical property and the chemical property and the uniformity thereof of extrudate rubber and plastic sizing material.
Common extrusion board production line screw extruder filters operation in the charging of rubber and plastic glue and adopts a screen pack, along with the gathering of impurity, contaminant filter must be removed in the production process, and screen pack also must be cleaned and changed.At this moment production line just should be put stopped status, to finish the removing of impurity safely.Because raw material place of production difference, inherent quality differs greatly, and impurity is cleared up frequently for a long time, and screen pack is changed also frequent.Make production line stop also frequent, greatly reduce extruded sheet Production Line efficient, the time-consuming production cost that also increases warming plate.Therefore, the major defect of extruded sheet production line screw extruder is exactly that operant level is low usually, and production efficiency is low.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of uninterrupted net replacer for screw extruder in plastic board producing line that draping is uninterrupted draping of can realizing not shutting down is provided.
The object of the present invention is achieved like this: a kind of uninterrupted net replacer for screw extruder in plastic board producing line, it is characterized in that it comprises: Hydraulic Station, net-changing device and left and right connecting pipe, net-changing device comprises oil cylinder, draping plate, connector and support, cylinder apparatus is on support, draping plate top is connected with the oil cylinder piston bar through connector, and upper and lower two opening of sieves are arranged on the draping plate, lets slip filter screen in the hole, the draping plate places between the left and right connecting pipe, and oil cylinder links to each other with Hydraulic Station.Like this, when changing filter screen in process of production, just can change easily, need not shut down and efficient quick, robust operation with two states in the HYDRAULIC CONTROL SYSTEM net-changing device.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present invention.
Fig. 2 is the left side view of Fig. 1.
Fig. 3 is a draping plate structure schematic diagram of the present invention.
Fig. 4 is the left side view of Fig. 3.
Among the figure: oil cylinder 1, connector 2, draping plate 3, left and right connecting pipe 4, support 5, opening of sieve 3.1, screen pack 3.2.
The specific embodiment
Referring to Fig. 1～2, uninterrupted net replacer for screw extruder in plastic board producing line of the present invention mainly is made up of Hydraulic Station (not shown), net-changing device and connecting pipe 4.Net-changing device is made up of oil cylinder 1, draping plate 3, connector 2 and support 5.Oil cylinder 1 is installed on the support 5, and draping plate 3 tops are connected with oil cylinder 1 piston rod through connector 2, and upper and lower two opening of sieves 3.1 are arranged on the draping plate 3, lets slip filter screen 3.2 (Fig. 3,4) in the hole.Oil cylinder 1 piston moves upward, and following hole and left and right connecting pipe 4 are connected, and rubber and plastic glue filters uses hole filter screen down, simultaneously can be to last hole screen replacing; Otherwise oil cylinder 1 piston moves downward, and last hole and left and right pipeline 4 are connected, and rubber and plastic glue filters just uses the hole filter screen, and to following hole screen replacing.Like this, XPS extrusion moulding type warming plate production line screw extruder has realized not stopping production draping.Under the not good enough situation of raw material quality, less than 2 hours must draping, now do not shut down, produce the production efficiency that uninterrupted draping has improved warming plate production line screw extruder greatly, draping time abundance has also been guaranteed the inherent quality of rubber and plastic offset plate.
