Further improvement of the utility model is that the macropore and aperture alternate intervals are arranged.
Further improvement of the utility model is that one end of the porous plate is equipped with groove.
Further improvement of the utility model is that the groove, described hole are in the surface of the end of the porous plate
It is straight.
Further improvement of the utility model is that the base diameter increase of the groove is formed with installation end, described recessed
The top of slot is formed with leading-in end.
Further improvement of the utility model is that the leading-in end is formed with transition with the installation end equipped with slope
End.
The beneficial effects of the utility model compared with the prior art lie in：
The hole that the utility model is differed by the way that diameter is arranged on porous plate, expanding the diameter of hole can be turned up in height
When fast-growing is produced in the unit interval plastic raw materials throughput, and some perforations diameter is reduced, is avoided since hole diameter becomes
Extrusion pressure is caused to become smaller greatly.Make porous plate under the premise of not destroying chemical plastic product plasticizing capacity (in extruder barrel
Need that certain pressure is kept to ensure the plasticizing capacity of plastic product), improve in high-speed production plastic raw materials in the unit interval
Throughput.And the hole that diameter differs is uniformly distributed, and be ensure that the uniformity of the extrusion capacity in high-speed production, is avoided
It is plasticized the backflow phenomenon and plugging phenomenon of raw material, ensure that the quality of product, can ensure that steady and continuous produces 10-12 days.

Specific implementation mode
Below in conjunction with attached drawing, technical characteristic above-mentioned to the utility model and other and advantage carry out clearly and completely
Description, it is clear that described embodiment is only the section Example of the utility model, rather than whole embodiments.
The utility model provides a kind of porous plate.The diameter of the hole of traditional porous plate is certain, and the production of extruder
The space that can be still improved, if but increase extrusion capacity, the pressure in machine barrel will be caused to greatly improve, and connect for a long time
Continuous production, it is uneven to be easy to cause plastic product runner, influences product quality.The utility model passes through the providing holes on porous plate
The hole that diameter does not wait does not increase the pressure in machine barrel again while improving production capacity, and extrusion capacity is uniform, ensure that the quality of product
Stablize.The structure of the porous plate of the utility model is illustrated below in conjunction with the accompanying drawings.
Refering to fig. 1,2, the utility model is a kind of porous plate, and multiple holes 1 to differ in size, hole are equipped on porous plate
Hole 1 is uniformly arranged on the surface of porous plate.Wherein, macropore 11 is the extrusion capacity for plastic raw materials, improves the production of production line
Can, and aperture 12 is to ensure the pressure in entire machine barrel in the tolerance range of machine barrel.
Because the cross section of porous plate is circular, in order to ensure the uniformity and stability that squeeze out.So hole 1 be
It is arranged in a ring on porous plate.The hole 1 that will be close to the axis of porous plate is set as inner collar, will be close to the edge of porous plate
Cyclic annular hole formation external toroidal ring is equipped with Raschig ring between inner collar and outer ring.Wherein, external toroidal ring and inner collar are by macropore 11
Composition, existing macropore 11 has aperture 12 again on Raschig ring, and on Raschig ring, macropore 11 and aperture 12 are to alternate to set
