Abstract
The utility model discloses a modified plastic extruder, which comprises an extruder cylinder provided with an exhaust tube. A glass fiber guide channel is arranged on the extruder cylinder, and an air tube communicated with the exhaust tube is disposed in the glass fiber guide channel. The modified plastic extruder resolves the problem that the occupied area of a production site is large and pretreatment process is complicated caused by the fact that a glass fiber preheating device needs to be independently arranged in order to heat glass fiber during production at present.
Description
Technical field
Technology for making field the utility model relates to plastics machinery system, especially a kind of machine barrel of extruder.
Background technology
At present in the production of modified plastics, frequent needs interpolation such as glass etc. improves the material of plastics performance, add in the modified plastics extruder of inlet having glass, often just being provided with glass simply on extruder barrel adds inlet, the modified plastics extruder of this structure is when producing, usually make moist because of glass, the moisture that moisture absorption brought and in extruder barrel, form aqueous vapor, the material modified performance that influence is produced, simultaneously owing to cold glass can cause the solution decrease of temperature to cause the melt flow variation after entering the extruder barrel inner chamber, be unfavorable for the dispersion of glass in material, the final modified plastics end properties that influences, thereby enter the machine barrel of extruder at glass and all preheat dry the processing as last, go up in order to preheat but produce at present to glass, often the glass preheating apparatus to be set separately, the easy like this production site that causes takies greatly the pretreating process complexity.
Summary of the invention
The utility model will provide a kind of modified plastics extruder, this modified plastics extruder can solve in the present production in order to preheat to glass, the glass preheating apparatus need be set separately, and cause production site to take greatly, the pretreating process complicated problems.
In order to address the above problem, the technical solution adopted in the utility model is: this modified plastics extruder, comprise the extruder barrel that is provided with exhaust tube, described extruder barrel is provided with the glass introduction channel, is provided with the tracheae that is communicated with described exhaust tube in the described glass introduction channel.More specifically scheme is, described glass introduction channel is made up of described extruder barrel and cover briquetting thereon, and the heater on the described extruder barrel heats the glass in the described glass introduction channel in to the heating of the plastics in the machine barrel inner chamber; The moisture that the tracheae that is communicated with described exhaust tube in the described glass introduction channel is produced after being heated by glass is able to rapid discharge, and the glass that assurance enters the machine barrel inner chamber is the dry glass with uniform temperature.
Owing to adopted such scheme, the utlity model has following effect: to have solved in the present production in order preheating, need the glass preheating apparatus to be set separately and to cause production site to take greatly, the pretreating process complicated problems to glass.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
As shown in Figure 1 be the extruder barrel part of this modified plastics extruder, other parts are identical with existing modified plastics extruder.On extruder barrel 1, be provided with exhaust tube 2; Glass introduction channel 3 is made of jointly pressing plate 4 and extruder barrel 1, and extruder barrel 1 is outside equipped with heater 5; Heater 5 heats the plastics in glass in the glass introduction channel 3 and the machine barrel 1 simultaneously; Bringing-up section and glass at glass introduction channel 3 enter between machine barrel 1 porch, by a conduit 6 glass introduction channel 3 is connected with exhaust tube 2 and is heated the moisture that produced of back in order to glass and is able to rapid discharge by glass introduction channel 3, the glass that assurance enters machine barrel inner chamber 5 is the dry glass with uniform temperature, thereby guarantees the quality of product.
