Description

The processing unit (plant) of decorative plastic sheets/plates

Technical field

The utility model relates to decorative plastic sheet material, sheet material, more particularly, relates to a kind of processing unit (plant) of decorative plastic sheets/plates.

Background technology

In the decorative plastic sheet material of making at screw extruder, sheet material, when decorative plastic sheet material, two needs different colours of sheet material, one well matched two screw rod extruders (Fig. 1) are made sheet material or three screw rod extruders (Fig. 2) making sheet material.

Take Fig. 2 as example, specifically, in decorative plastic sheet material, board production equipment, realize in the following manner:

In vertical frame 1 inboard, three tangent felt wrapped rolls 2, felt wrapped roll 3 and the felt wrapped roll 4 from bottom to top arranged:

At a side screw extruder 11 of frame 1, enter the middle entrance of proportioning valve 9 through runner 12, constant displacement pump 13;

Surperficial demand color layers screw extruder 6 and screw extruder 14 are set respectively in the above and below of screw extruder 11; Screw extruder 6, enter an entrance of proportioning valve 9 through runner 7, constant displacement pump 8, screw extruder 14 enters another entrance of proportioning valve 9 through runner 15, constant displacement pump 16; Flat mouth mould 10 is connected in the outlet of proportioning valve 9; The outlet of flat mouth mould 10 is over against the entry entered between felt wrapped roll 2 and felt wrapped roll 3.

Proportioning valve 9 is for regulating three flow proportionals that entrance is different.

Three screw extruders respectively adjust its rotating speed to carry out coarse adjustment material extrusion capacity separately, then realize regulating the accurate quantity delivered of material separately by entering allocation proportion valve 9 after constant displacement pump, thereby realize the allocation proportion of materials demand; After being extruded into wide square-section in allocation proportion valve 9, three kinds of materials enter flat mouth mould 10, be flowed to together and extrude after launching in the cavity volume separately of material in mould, if during three making sheet material, material is in centre, top and bottom need the different colours aesthetic layer, material 5 after extruding, by the extrusion modling of felt wrapped roll 2,3,4, is sent to cooling cutting back segment, realizes whole process production.

In this production process, it is the new product raw material that top and bottom need the materials of different colours aesthetic layer, and intermediate layer can be reclaimed materials or new and old batch mixing or virgin material.Top and bottom need the different colours aesthetic layer because device relationships thickness is larger, generally are greater than more than 0.25.There are three weak points in the decorative plastic sheet material of making of the screw rod extruder like this, sheet material: one. and top and bottom need different colours aesthetic layer virgin material consumption large, and decorative plastic sheet material, sheet material cost of material are high; Two. use equipment is many, increases cost, unfavorable equipment promotion to user's purchase of equipment; Three. need different colours aesthetic layer dullness, single face can only be homochromy, can not the many variety popularizations of satisfying the market.

Therefore, minimizing raw material of fabric cost, reduction equipment price, increase decorative plastic sheet material, sheet material designs and varieties are key to the issue places.

The utility model content

For the defect existed in prior art, the purpose of this utility model is to provide a kind of processing unit (plant) of decorative plastic sheets/plates.

For achieving the above object, the utility model adopts following technical scheme:

A kind of processing unit (plant) of decorative plastic sheets/plates, comprise frame, and the arranged vertically felt wrapped roll group be comprised of three the first tangent felt wrapped rolls, the second felt wrapped roll and the 3rd felt wrapped roll from bottom to top on described frame also comprises:

Screw extruder, runner, flat mouth mould, the first aesthetic layer coiled strip and the second aesthetic layer coiled strip, the input port of described runner communicates with the delivery outlet of described screw extruder, and the input port of described flat mouth mould communicates with the delivery outlet of described runner; On entry between described the first felt wrapped roll and the second felt wrapped roll and the delivery outlet same level of described flat mouth mould;

The coiled strip opening of described the first aesthetic layer coiled strip enters the second felt wrapped roll along the rotation direction of the second felt wrapped roll from the entry front of the first felt wrapped roll and the second felt wrapped roll;

The coiled strip opening of described the second aesthetic layer coiled strip enters the 3rd felt wrapped roll along the rotation direction of the 3rd felt wrapped roll from the entry front of the second felt wrapped roll and the 3rd felt wrapped roll.

The thickness range of described the first aesthetic layer coiled strip or the second aesthetic layer coiled strip is 0.1-0.15mm.

Described the first aesthetic layer coiled strip or the second aesthetic layer coiled strip lay respectively at the both sides of felt wrapped roll group.

Compared with prior art, adopt the processing unit (plant) of a kind of decorative plastic sheets/plates of the present utility model, only need a screw extruder to make decorative plastic sheet material, the middle base-material of sheet material, reduced by two screw rod extruders, thereby reduced the cost of user's purchase of equipment.The first aesthetic layer coiled strip and the second aesthetic layer coiled strip are all the finished products of buying, and market is by the additive method batch making, and color is various, thereby make decorative plastic sheet material, sheet material kind also become diversified.

As further improved plan, the first aesthetic layer coiled strip and the second aesthetic layer coiled strip general thickness be at 0.1-0.15, and its thickness is directly to extrude half of thickness in prior art, so raw material has also been saved half.In sum, the novel processing unit (plant) of this reality is of value to the cost that reduces user's purchase of equipment; Be of value to the variation that becomes of decorative plastic sheet material, sheet material kind; Be of value to the saving of surface aesthetic layer new product raw material.

The accompanying drawing explanation

The structural representation of the processing unit (plant) that Fig. 1 is the first decorative plastic sheets/plates of the prior art;
