Abstract
The utility model discloses a forced feeding device of a hotly-feeding extruder. The forced feeding device comprises a forced feeding roller mounted at one side of an extruding screw rod at a feeding opening of the extruder, and a driving device, wherein the driving device drives the forced feeding roller to rotate; the forced feeding roller is provided with two or more than two pieces of material scraping sheets; and mounting angles of the adjacent two material scraping sheets are different. According to the forced feeding device disclosed by the utility model, the forced feeding roller is mounted at the feeding opening of the extruder, so that a fused material conveyed by a mixer is brought into a screw groove of the extruding screw rod to be pushed to move forwards; the feeding capability is improved; and the problems of unsmooth machining, material clamping of a machine, high rejection rate and the like can be avoided.
Description
Technical field
The utility model belongs to the extruder technology field, is specifically related to a kind of hot-feed extruder forced feed device.
Background technology
In the process of rubber or plastic or other material, mixing through mixing roll earlier, and then the fused materials that will be molten condition is sent into the screw rod of extruder, carry out extrusion molding by this extruder again, but when fused materials is sent into extruder, the extruder charging aperture does not have propulsion plant, is difficult to fused materials is pushed in the middle of the screw channel of extrusion screw rod fully, can cause just therefore that processing has some setbacks, a series of problems such as machine gets stuck, scrappage height.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, a kind of hot-feed extruder forced feed device is provided, fused materials that it can be sent into mixing roll is forced in the middle of the screw channel of feeding extruder screw, avoids occurring that processing has some setbacks, problems such as machine gets stuck, scrappage height.
The technical scheme that the utility model adopts is: a kind of hot-feed extruder forced feed device, comprise the forced feed roller and the drive unit that are installed on extruder charging aperture extrusion screw rod one side, described drive unit drives the running of forced feed roller, described forced feed roller is provided with the tablet of scraping more than two or two, and adjacent two to scrape the setting angle of tablet inequality.
As preferably, adjacent two scrape that setting angle differs 180 degree between tablet.
As preferably, adjacent two scrape that the gap is zero between tablet.
As preferably, the screw thread of the described movable end of scraping tablet and described extrusion screw rod is tangent.
As preferably, described drive unit is the gear synchronous with the screw drive wheel, and it drives described forced feed roller and extrusion screw rod run-in synchronism by the screw drive wheel.
As preferably, described drive unit is drive motors, and it drives described forced feed roller and extrusion screw rod antiport by belt pulley.
The beneficial effects of the utility model are: because the utility model is provided with the forced feed roller in extruder charging aperture position, it can be forced to the fused materials of being sent into by mixing roll bring among the screw channel of extrusion screw rod, promote forward, improved the feeding ability, avoided occurring that processing has some setbacks, problems such as machine gets stuck, scrappage height.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, charging aperture; 2, extrusion screw rod; 3, forced feed roller; 4, drive unit; 5, scrape tablet; 6, screw thread; 7, screw drive wheel.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of hot-feed extruder forced feed device, comprise the forced feed roller 3 and the drive unit 4 that are installed on extruder charging aperture 1 extrusion screw rod 2 one sides, described drive unit 4 drives 3 runnings of forced feed roller, described forced feed roller 3 is provided with scrapes tablet 5 more than two or two, adjacent two to scrape the setting angle of tablet 5 inequality, it can be to differ 90 degree, 180 degree or other angles, it can make forced feed roller 3 better fused materials to be pushed in the screw channel of extrusion screw rod 2, in the present embodiment adjacent two scrape 5 setting angles of tablet differ 180 the degree.
Because the utility model is provided with forced feed roller 3 in extruder charging aperture 1 position, it can be forced to the fused materials of being sent into by mixing roll bring among the screw channel of extrusion screw rod 2, promote to have improved the feeding ability forward, avoid occurring that processing has some setbacks, problems such as machine gets stuck, scrappage height.
Preferably, adjacent two to scrape 5 gaps of tablet be zero, avoids fused materials to scrape 5 leakages of tablet by two and go out.
Preferably, the screw thread 6 of the described movable end of scraping tablet 5 and described extrusion screw rod 2 is tangent, avoids fused materials by revealing away in the gap of scraping between tablet 5 and the extrusion screw rod 2.
In addition, described drive unit 4 is for to take turns 7 synchronous gears with screw drive, it drives described forced feed roller 3 and extrusion screw rod 2 run-in synchronisms by screw drive wheel 7, it adopts the power of screw drive wheel 7 to drive, need not to provide other power resources, rationally utilize power resource, saved a large amount of electric costs.But described drive unit 4 also can be drive motors independently, and it drives described forced feed roller 3 and extrusion screw rod 2 antiports by belt pulley, can better fused materials be forced push in the screw channel of extrusion screw rod 2.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
