Abstract
The utility model relates to a handpiece of a rubber sheet extruder. The handpiece comprises an extruder barrel with a feeding hole, wherein an extrusion runner is arranged at the end part of the extruder barrel; an extrusion screw is axially arranged inside the extruder barrel; a die plate communicated with the extrusion runner is arranged at the end part of the extruder barrel; a porous baffle plate is arranged between the part of the extruder barrel, near the end part, and the extrusion runner; a filter mesh is arranged between the baffle plate and the end part of the extrusion screw. The handpiece of the rubber sheet extruder provided by the utility model is simple in structure. The filter mesh is arranged in front of the porous baffle plate, thus impurities in a sizing material can be filtered out, and the quality of the rubber sheet is ensured. The filter mesh is added to the handpiece of the extruder, so that the operation is relatively simple, the requirements that the sheet is uniform in thickness, compact, free of bubbles, smooth and free of impurities can be met, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of parts of rubber sheet extruder, relates in particular to a kind of head of rubber sheet extruder.
Background technology
In the time manufacturing rubber diaphragm, because diaphragm thickness is thinner, must the certain thickness sizing material thin slice of preformed.And rubber diaphragm is had relatively high expectations, except thickness requirement, product is also wanted the air pressure of bearing certain pressure, and can not have impurity.Be generally that mill regulates the thickness of thin slice by roll spacing by mill roll extrusion preformed slice, make the rubber sheet that rolls out in uneven thickness, production efficiency is low.Sizing material is brought air in the time of roll extrusion simultaneously, makes rubber sheet surface have minute bubbles, affects product quality.In elastomeric compound, itself also have in addition some impurity and exist, finally affect rubber diaphragm quality and air-tightness.
Utility model content
The utility model has overcome the deficiencies in the prior art, provide a kind of simple in structure, can guarantee rubber sheet even thickness, the closely knit head without bubble, smooth pure extruder.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rubber sheet cross-head, comprise the extruder barrel that is provided with spout, the end of described machine barrel is provided with extrusion channel, in described machine barrel, be axially arranged with extrusion screw rod, described machine barrel end is provided with the die panel communicating with its extrusion channel, it is characterized in that: described machine barrel, near being provided with cavernous baffle plate between its end and described extrusion channel, is provided with filtering net plate between described baffle plate and described extrusion screw rod end.
In preferred embodiment of the utility model, the shape that further comprises that the cross section of described baffle plate is " recessed ", the equal diameters of the diameter of described filtering net plate and described baffle plate recess is also fastened on the recess of described baffle plate.
In preferred embodiment of the utility model, further comprise that described machine barrel end is provided with a pair cross-section for " that arrange and that one end is hinged the in opposite directions holding section of (" shape, described baffle wedge is located in described holding section, and the other end of described two holding sections is locked by steady pin.
In preferred embodiment of the utility model, further comprise that described die panel is cuboid, described die panel is provided with the outlet that runs through its rectangular bar shaped in both sides.
In preferred embodiment of the utility model, further comprise that described outlet both sides are equipped with the fixing hole that several run through described die panel both sides.
The utility model has solved the defect existing in background technology, and a kind of rubber sheet cross-head of the present utility model is simple in structure, by filtering net plate being set before cavernous baffle position, can filter out impurity in sizing material, has guaranteed the quality of rubber sheet; By installing filtering net plate additional at cross-head, also simpler in operation, can meet sheet thickness even, closely knit without bubble, smooth pure requirement, greatly improve production efficiency.

Detailed description of the invention
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 4, a kind of rubber sheet cross-head, comprise the extruder barrel 10 that is provided with spout 11, the end of machine barrel 10 is provided with extrusion channel 12, in machine barrel 10, be axially arranged with extrusion screw rod 20, machine barrel 10 ends are provided with the die panel 30 communicating with its extrusion channel 12, and machine barrel 10, near being provided with cavernous baffle plate 40 between its end and extrusion channel 12, is provided with filtering net plate 50 between baffle plate 40 and extrusion screw rod 20 ends.Concrete, the cross section of baffle plate 40 is " recessed " shape, and the equal diameters of the diameter of filtering net plate 50 and baffle plate 40 recess is also fastened on filtering net plate 50 recess of baffle plate 40.
Baffle plate 40 can be fixed by mode as shown in Figure 3, a pair cross-section is set in opposite directions for " holding section 60 (" shape and that one end is hinged, is fastened on baffle plate 40 in holding section 60, and the other end of two holding sections 60 is locked by steady pin 70 in machine barrel 10 ends.
Further, die panel 30 in the utility model is cuboid, as shown in Figure 4, die panel 30 is provided with the outlet 31 that runs through its rectangular bar shaped in both sides, export the fixing hole 32 that 31 both sides are equipped with several impenetrating mouth template 30 both sides, convenient by die panel 30 by screw fastening on extrusion channel 12.
When use, filtering net plate 50 is placed on before perforated baffle 40 positions in advance, and die panel 30 is fixed on to extrusion channel 12 places, open extruder main motor, rectangular elastomeric compound is entered to machine barrel 10 from spout 11, through shearing and the stirring mineralization pressure of screw rod 20, when extruding, can not bring air into, guarantee that rubber sheet surface can not produce minute bubbles, sizing material is squeezed to machine barrel 10 ends, after prepositioned filtering net plate impurity screening, through die panel 30 extruded rubber thin slices, the thickness that the rotating speed control rubber sheet of adjustable screw 20 is extruded, after dimensionally stable, extruding severing collects, can complete the preformed of rubber sheet.
