Background technology

Cold drawn production line of existing double screw extruder, owing to adopt loading hopper, operator's labour intensity is big, is easy to generate the problem of meropodium material screen choosing difficulty; In addition, because the wire drawing bar does not separate, entrapped moisture causes the product moisture content higher easily, is easy to generate the moisture filamentary silver when injection moulding, has had a strong impact on the outward appearance of plastic products; In addition, because the product moisture content is higher, inventory time is shorter, baking material difficulty when injection moulding, the output of plastic products when having had a strong impact on injection moulding.

The utility model content

In view of this, the utility model provides a kind of double screw extruder cold drawn dry separation of produced line, by on existing production line, increasing dry separation equipment, can realize the drying of cold drawn of double screw extruder is separated, its automaticity height, operation is provided with rationally, and the finished particle quality is good.

The purpose of this utility model provides cold drawn dry separation of produced line of a kind of double screw extruder, cold drawn dry separation of produced line of double screw extruder, comprise screw extruder, the exit position of described screw extruder is equipped with a mouthful mould, also comprise the draw-gear, the granulate equipment that set gradually along cold drawn shaping direction, cold drawn dry separation of produced line of described double screw extruder also comprises dry piece-rate system, described dry piece-rate system is arranged on after the granulate equipment, is used for that cold drawn particle after the pelletizing carried out drying and separates;

Described dry separation equipment comprises the one-level blower fan, conveyance conduit I, cyclone separator I, drying machine, vibratory sieve, the secondary blower fan, conveyance conduit II, cyclone separator II and cooling storehouse, the corresponding setting of the charging aperture of described conveyance conduit I with the discharging opening of granulate equipment, described one-level blower fan is arranged near the charging aperture of conveyance conduit I, the discharging opening of described conveyance conduit I is connected with the charging aperture of cyclone separator I, the discharging opening of described cyclone separator I and the feeding inlet of drying machine, cold drawn particle after pelletizing is blown into cyclone separator I by the one-level blower fan via conveyance conduit I, enters drying machine by cyclone separator II again; The corresponding setting of the discharging opening of described drying machine with the charging aperture of vibratory sieve, the charging aperture of described conveyance conduit II is arranged on the discharging opening below of vibratory sieve, described secondary blower fan is arranged near the charging aperture of conveyance conduit II, the discharging opening of described conveyance conduit II is connected with the charging aperture of cyclone separator II, the discharging opening of described cyclone separator II and the feeding inlet of cooling off the storehouse, garbled cold drawn particle is blown into cyclone separator II by the secondary blower fan via transfer passage II, enters the cooling storehouse by cyclone separator II again.

Further, described cyclone separator I, one-level blower fan, drying machine, vibratory sieve, secondary blower fan and cyclone separator II all are electrically connected with control module and realize control automatically by control module.

The beneficial effects of the utility model are:

The utility model automaticity is higher, has promoted production efficiency, has alleviated operative employee's labour intensity simultaneously, has improved the quality of product, and finished particle is even, in addition, has also prolonged the inventory time of product.When this finished particle was used for the product injection moulding, the product appearance quality that obtains obviously promoted.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
