Abstract
The utility model discloses a feeding device in an extruding machine, which can ensure the feed quantity of material. The feeding device comprises a feeding hopper, a pair of mutually parallel feeding rollers is arranged in the feeding hopper, the both ends of the feeding rollers are respectively movably supported on the side walls at the both sides of the feeding hopper, and one of the feeding rollers is connected with a driving device. The feeding device is mainly used in the extruding machine for waste plastic recycling and granulating.
Description
Technical field
The utility model relates to and is used for extruder for pelletizing recovered waste plastic, refers more particularly to the drawing-in device in the extruder.
Background technology
At present, be used for the structure of the drawing-in device of extruder for pelletizing recovered waste plastic all very simply, this drawing-in device is exactly a feeding hopper that is provided with " loudspeaker " shape spout.This drawing-in device is when running into the lighter material of some bulk densities such as plastic sheeting, since material under feeding hopper to the barrel of extruder unusual difficulty, make to feed to the inventory of barrel to can not get fine assurance, thereby cause the production efficiency of extruder to reduce greatly from feeding hopper; And above-mentioned feeding hopper and discharging opening thereof are all narrow, and the length of discharging opening is usually all less than two pitch sums of the screw rod in the extruder.
The utility model content
Technical problem to be solved in the utility model is: the drawing-in device in a kind of extruder that can guarantee the material feed quantity is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the drawing-in device in the extruder, comprise: feeding hopper, be provided with a pair of feeding roller that is parallel to each other in the feeding hopper, expansion bearing is on the sidewall of the both sides of feeding hopper respectively at the two ends of feeding roller, and wherein a feeding roller is connected with drive unit.
The roll surface of above-mentioned feeding roller is provided with some pointed tooth bars.
The length of the discharging opening of above-mentioned feeding hopper is not less than three pitch sums of the screw rod in the extruder, and the diameter of the barrel in width and the extruder is suitable.
A kind of concrete structure of above-mentioned drive unit comprises: motor and speed reducer, and the output shaft of motor links to each other with the power shaft of reductor, and the output shaft of reductor is connected with a feeding roller.
The beneficial effects of the utility model are: drawing-in device described in the utility model has guaranteed the feed quantity of material, thereby has also just guaranteed the production efficiency of extruder owing to be provided with a pair of feeding roller.In addition, the discharging opening of the feeding hopper in this drawing-in device is more a lot of greatly than the discharging opening of conventional feeding hopper, has improved the feed quantity of material in the unit interval significantly, thereby has improved the production efficiency of extruder significantly.

The specific embodiment
As shown in Figure 1 and Figure 2, drawing-in device in the extruder described in the utility model, comprise: feeding hopper 4, be provided with a pair of feeding roller that is parallel to each other 6 in the feeding hopper 4, the roll surface of feeding roller 6 is provided with some pointed tooth bars 61, expansion bearing is on the sidewall of the both sides of feeding hopper 4 respectively in the rotating shaft 62 at feeding roller 6 two ends, and the rotating shaft 62 of a side of one of them feeding roller 6 links to each other with the output shaft of reductor 3, and the power shaft of reductor 3 links to each other with the output shaft of motor 2.In the present embodiment, for convenience of feeding, the top of described feeding hopper 4 is " loudspeaker " shape.As shown in Figure 3, barrel 8 is installed on the frame 1, be provided with screw rod 7 in the barrel 8, described drawing-in device is arranged on the top of barrel 8, the discharging opening of its feeding hopper 4 is corresponding with the charging aperture on the barrel 8, the length L of the discharging opening of feeding hopper 4 is not less than three pitch sums of screw rod 7, and the diameter of width and barrel 8 is suitable.
In practical work process, driving reductor 3 by motor 2 rotates, reductor 3 drives feeding roller 6 again and rotates, send into material in the feeding hopper 4 under the drive of the pointed tooth bar 61 on the roll surface of feeding roller 6, between a pair of feeding roller 6, be forced to send into the barrel 8, so just guarantee the feed quantity of material, thereby also just guaranteed the production efficiency of extruder.In addition, the discharging opening of the feeding hopper 4 in this drawing-in device is more a lot of greatly than the discharging opening of conventional feeding hopper, has improved the feed quantity of material in the unit interval significantly, thereby has improved the production efficiency of extruder significantly.
