The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figures 1 to 3, a kind of feeding hopper of extruder, comprise bucket body, and bucket body comprises the storing section 2 of back taper and the discharging section 3 of annular, and storing section 2 is coaxial setting with discharging section 3, the top of storing section 2 is provided with cover plate 4, cover plate 4 is provided with charging aperture 41, the top of cover plate 4 is provided with drive motors 5, drive motors 5 connects one and stretches into the inner main shaft 6 arranged of bucket body, be arranged at intervals with the loose blade construction of many groups on main shaft 6, loose blade construction is arranged in storing section 2, every group of loose blade construction comprises at least 4 loose blades 62 that annular is uniform, each loose blade 62 is for being obliquely installed, and the blade face of each loose blade 62 is towards the rotation direction setting of main shaft 6, the end of main shaft 6 is provided with helical blade 63, helical blade 63 is arranged in discharging section 3.
The feeding hopper of extruder of the present invention, by the storing section 2 of employing back taper and the combining structure of columniform discharging section 3, can be so that material slides along the back taper sidewall under the effect of inverted cone-shaped structure and material deadweight, enter in discharging section 3, in discharging section 3, the helical pressure effect general material wherein of recycling helical blade 63 is by force to lower nip, the assurance material can be sent in the barrel of extruder in time, guarantees the normal operation of extruder; And at material during in storing section 2, rotation by the loose blade construction on main shaft 6 realizes repeatedly loosening to material, avoid material to pile up for a long time and impact enters the discharging after discharging section 3, the pressure of material in the time of also can reducing helical blade 63 force feed material in storing section 2 to the material formation of discharging section 3, avoid occurring " bridge formation " phenomenon, make the feeding hopper feeding of this extruder easy, and only at 3 pairs of materials of discharging section, carry out force feed by force, can greatly reduce the power consumption of feeding.In addition, the force feed of the helical blade 63 by discharging section 3, the deal of the material of sending is more prone to be consistent, can not cause the burden that the charging barrel charge door of extruder is formed to material moment accumulation, more can guarantee the mass transport quality of extruder, contribute to improve the quality of the extruded product of extruder.
For the loose blade construction that makes differing heights place on main shaft 6 can coordinate well with the inboard of storing section 2, to reach the purpose of bulk material preferably, in the present embodiment, the appearance and size of every group of loose blade construction adapts with the size of corresponding storing section 2.And every group of loose blade construction comprises 4 loose blades 62.Like this, at main shaft 6, drive in the process of loose blade construction rotation, loose blade 62 in every group of loose blade construction will intermittently loosen to the material around it repeatedly, avoid solid accumulation, and then avoid temperature in storing section 2 to rise, thereby guarantee that material can store well in storing section 2 and for the discharging of discharging section 3.
Concrete, after loose blade 62 is obliquely installed, and face of blade is towards the direction setting of main shaft 6 rotations, like this, when loose blade 62 rotates at main shaft 6, minimum point 622 places on it will be positioned on the lower material bed upper, and the peak 621 on this its will be positioned at top material bed upper, like this, material in the aspect space formed at minimum point 622 and peak 621 blade 62 that all can be loosened when main shaft rotates digs, reach loose purpose, also can dispel the heat, avoid material bonding.Thereby, by the differing heights at main shaft 6, loose blade construction is set, can realize the loose of material in the certain altitude space.
The feeding hopper of extruder of the present invention, be provided with the feed zone 1 of annular at the top of storing section 2, the dismountable opening part that is arranged at feed zone 1 of cover plate 4, increased greatly the storing space of bucket body inside, each feeding in raw material can add more material in feeding hopper, avoid repeatedly feeding in raw material, reduce labour intensity.
Further, in the present embodiment, the epimere of feed zone 1 is provided with upper limit site, upper limit site is provided with upper limit sensor 7, the hypomere of storing section 2 is provided with the lower limit site, the lower limit site is provided with lower limit sensor 8, the alarm that bucket body also is provided with controller and is connected with controller, and upper limit sensor 7 all is connected with controller with lower limit sensor 8; Material position in bucket body is during lower than the lower limit site, and lower limit sensor 8 sends to controller by this signal, and controller is controlled the alarm alarm that feeds in raw material; Material position in bucket body is during higher than upper limit site, and upper limit sensor 7 sends to controller by this signal, and controller is controlled alarm and stopped reinforced alarm.Be no matter Artificial Control to reinforced in feeding hopper, or, by auto feed, feeding hopper of the present invention can play regularly punctual prompting, to avoid in feeding hopper lacking, expects and causes the idle running of extruder.
Wherein, alarm is buzzer siren or polychrome signal lamp.
When material when the charging aperture 41 of cover plate 4 enters bucket body, because the speed of giving the feeding hopper charging generally can be greater than the rate of feeding of feeding hopper to extruder, thereby material can be from discharging section 3 until feed zone 1 starts to pile up increases, but, overflow bucket body for avoiding material excessively to pile to press under charging aperture 41, also avoid material too much can make heap pressure exceed helical blade 63 and can rotate born pressure, also be provided with a plurality of cross bars 61 of annular arrangement on main shaft 6, and, the position of cross bar 61 on main shaft 6 and the position in upper limit site adapt, at material, enter in the process of bucket body, utilize cross bar 61 to follow the material promotion of the rotation of main shaft 6 to charging aperture 41 belows, so that material is dispersed in whole feed zone 1, and then also can make upper limit sensor 7 can detect more exactly material whether to reach this upper limit site, to send accurately signal to controller, and then make controller control alarm send alarm signal accurately.
Wherein, the end of cross bar 61 approaches the inboard setting of feed zone 1.
Wherein, be provided with 4 cross bars 61 of annular arrangement on main shaft 6.
Wherein, 2/3 of the diameter of bore that the external diameter of helical blade 63 is discharging section 3.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present invention, within these modes all will fall into protection scope of the present invention.
