Abstract
The utility model relates to the technical field of extruders, and in particular relates to a filtering plate of an extruder. The filtering plate of the extruder is installed between a machine cylinder and a machine head of the extruder and comprises an outer filtering plate edge and a filtering plate main body, wherein the outer filtering plate edge and the filtering plate main body are integrally formed; a filtering hole channel is formed in the filtering plate main body; the filtering hole channel is sequentially divided into a machine cylinder section, a middle section and a machine head section; as the diameter of the machine cylinder section is larger than the diameter of the middle section, molten materials can flow into the filtering hole channel easily; and as the diameter of the machine head section is larger than the diameter of the middle section, the molten materials can flow out of the filtering hole channel easily. Due to the filtering hole channel adopted by the filtering plate, the molten materials can smoothly flow in and flow out, so that the blocking caused when the molten materials flow through the filtering plate of the extrude is avoided.
Description
Technical field
The utility model relates to the extruder technology field, is specifically related to a kind of extruder filter plate.
Background technology
The effect of cross-head is that the plastic melt that will rotatablely move changes the parallel lines motion into, in the importing die sleeve of uniform and stable, and gives the briquetting pressure of plastics with necessity.Plastics plastify compacting in machine barrel, flow into head shaping mould along certain runner by the head neck through the porous filter plate.
Existing porous filter plate, the filter bores in it is cylindrical hole, some temperature-sensitive material easily stops up during the stream of plastic filter when extrusion temperature is too high.The patent No. is that the Chinese utility model patent of CN201020263758.1 discloses a kind of filter plate of screw extruder, described filter plate is arranged between the machine barrel and head of extruder, the filter plate main body that is provided with filter opening that described filter plate comprises the filter plate outer rim, links into an integrated entity with the filter plate outer rim, described filter opening is bellmouth, path is located at the machine barrel side, the head side is located in large footpath, though have some improvement, but the obstruction that causes can not avoid the flow of molten materials filter time.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of extruder filter plate, the obstruction that this kind extruder filter plate causes in the time of can effectively avoiding fused materials to flow through the extruder filter plate.
The utility model is realized by following technology:
A kind of extruder filter plate, described extruder filter plate is arranged between the machine barrel and head of extruder, described extruder filter plate comprises filter plate outer rim and filter plate main body, described filter plate outer rim and filter plate main body are one-body molded, described filter plate main body offers filters the duct, described filtration duct is divided into barrel section, interlude and head section successively, and the diameter of described barrel section is greater than the diameter of described interlude, and the diameter of described head section is greater than the diameter of described interlude.
Wherein, be connected for arc transition between described filter plate main body and filter plate outer rim.
Wherein, described barrel section, described interlude and the head section of being connected are that arc transition connects.
The beneficial effects of the utility model are: filtration of the present utility model duct is divided into barrel section, interlude and head section successively, the diameter of barrel section is greater than the diameter of interlude, fused materials is easily flow to filter the duct, the diameter of head section is greater than the diameter of interlude, can make the easy outflow filter of fused materials duct, the utility model adopts filtration duct can make fused materials flow to very swimmingly and flow out, the obstruction that causes when avoiding fused materials to flow through the extruder filter plate.

The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the utility model is further described, the content that embodiment is mentioned not is to restriction of the present utility model.
see Fig. 1 and Fig. 2, a kind of extruder filter plate, the extruder filter plate is arranged between the machine barrel 1 and head 2 of extruder, the extruder filter plate comprises filter plate outer rim 3 and filter plate main body 4, filter plate outer rim 3 and filter plate main body 4 are one-body molded, filter plate main body 4 offers filters duct 5, filter duct 5 and be divided into successively barrel section 6, interlude 7 and head section 8, the diameter of barrel section 6 is greater than the diameter of interlude 7, fused materials is easily flow to filter duct 5, the diameter of head section 8 is greater than the diameter of interlude 7, can make the easy outflow filter of fused materials duct 5, the utility model adopts filtration duct 5 can make fused materials flow to very swimmingly and flow out, the obstruction that causes when avoiding fused materials to flow through the extruder filter plate.
For arc transition is connected, make the fused materials of the junction ground that flows more smooth and easy between filter plate main body 4 and filter plate outer rim 3, avoid the dead angle to cause prolonged stay and the high temperature cabonization of fused materials.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
