Abstract

The utility model provides a foam particle mixing device for even mixing and convenient adjustment, which comprises a first hopper, a second hopper, a first feeding device, a second feeding device, a feeding tube and a fan; wherein, the first hopper and the second hopper are respectively connected with the feeding inlet of the feeding tube, the air outlet of the fan is connected with the feeding inlet of the feeding tube, the first feeding device is arranged between the discharge outlet of the first hopper and the feeding inlet of the feeding tube, and the second feeding device is arranged between the discharge outlet of the second hopper and the feeding inlet of the feeding tube. So material in two hoppers can be quantitatively fed to feeding tube respectively through two feeding devices, and can be mixed in conveying process under the effect of the fan, so as to realize the even mixing effect.

Description

A kind of foam beads mixing arrangement

Technical field

The utility model relates to a kind of foamed plastics making apparatus, relates in particular to a kind of foam beads mixing arrangement.

Background technology

Known foamed plastics making apparatus generally comprises hopper, conveying pipeline, air blast, die cavity, heating pressue device etc.The Chinese patent CN1298339A that announces June 6 calendar year 2001 discloses a kind of interior foaming and forming apparatus of type and method that is used for synthetic resin and reaches foamed molded product in the type of making thus, this technical scheme relates to the feed particles feeding mechanism, it is will comprise that by means of air stream the feed particles of thermoplasticity synthetic resin is transported to the die cavity of core and swaging die composition through tucker from head tank, is exactly the foam beads shaped device in fact.In order to prevent that foam beads from stopping up in course of conveying, on August 29th, 2007, the Chinese patent CN200939668Y of bulletin disclosed a kind of foam beads charging gear, the conveying pipeline that it comprises hopper and connects the hopper discharging opening, conveying pipeline also connects the air outlet of air blast, be provided with a rotor between hopper discharging opening and the conveying pipeline, the rotor circumference lateral wall is provided with at least three feeding blades, and the vertical end of described rotor connects clutch end.The rotor of band feeding blade is set by the discharging opening at hopper, and blade end is provided with hairbrush, make foam beads enter conveying pipeline quantitatively by feeding blade, prevent that the air in the conveying pipeline from discharging from the hopper discharging opening, thereby in conveying pipeline, set up certain pressure, prevent that putty from taking place.Variation along with the market demand, sometimes need different types of foam beads mixed and produce foam plastic product, common way is to add material bin after manually mixing or directly two kinds of raw materials are added to same hopper, nationality is mixed by two kinds of material motions in conveyance conduit, the weak point of aforementioned two kinds of hybrid modes is that mixing is inhomogeneous, the foam plastic product quality instability that makes.

The utility model content

The purpose of this utility model provides a kind of foam beads mixing arrangement, and it is used for two kinds of different graininess or powdered substance are mixed, and requires easy to adjust.

The technical scheme that the utility model adopted is such: a kind of foam beads mixing arrangement; comprise first hopper, second hopper, first charging gear, second charging gear, feed pipe and blower fan; described first hopper and second hopper are connected with the charging aperture of feed pipe respectively; the air outlet of blower fan is connected with the charging aperture of feed pipe; first charging gear is located between the charging aperture of the feed opening of first hopper and feed pipe, and second charging gear is located between the charging aperture of the feed opening of second hopper and feed pipe.

Above-mentioned foam beads mixing arrangement; described first charging gear is made up of drive motors, rotating shaft and plurality of vanes; drive motors is located at first hopper outside; rotating shaft one end and drive motors are in transmission connection; the rotating shaft other end extends to the first hopper feed opening inboard; each blade along the circumferential direction evenly is located on the rotating shaft lateral wall of the first hopper feed opening inboard, and the structure of described second charging gear is identical with the structure of first charging gear.

An above-mentioned foam material mixing plant, described drive motors are electrically connected with asynchronous machine by frequency converter to be formed.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the material of two hoppers is rendered to quantitatively in the feed pipe by charging gear separately respectively and is carried the limit to mix to reach mixed uniformly effect in that the effect of blower fan is following, can adjust both relative input ratios as long as adjust the delivery rate of each hopper feed device simultaneously, easy to operate.

Description of drawings

Fig. 1 is the utility model example structure schematic diagram;

The specific embodiment

The utility model is the improvement of being done on the basis of the disclosed a kind of foam of a Chinese patent CN200939668Y material charging gear of on August 29th, 2007 bulletin, its objective is to be used for two kinds of foam beads are mixed before moulding.

With reference to figure 1; embodiment discloses a kind of foam beads mixing arrangement; comprise hopper 1; hopper 2; feed pipe 3; first charging gear 4; second charging gear 5 and blower fan (not shown); wherein hopper 1 is for having the bucket-shaped structure of a constant volume; which is provided with charge door and feed opening; hopper 2 structures are identical with hopper 1; first charging gear 4 comprises the threephase asynchronous machine (not shown); rotating shaft 41 and six blades 42; described threephase asynchronous machine is located at hopper 1 outside; the input of this threephase asynchronous machine is electrically connected with frequency converter so that adjust the rotating speed of threephase asynchronous machine; rotating shaft 41 1 ends and threephase asynchronous machine are in transmission connection; rotating shaft 41 other ends extend to hopper 1 feed opening inboard; six blades 42 along the circumferential direction evenly are located on the lateral wall of the described rotating shaft 41 that is positioned at hopper 1 feed opening inboard; second charging gear 5 is identical with the structure of first charging gear 4; the feed opening of the feed opening of hopper 1 and hopper 2 is connected with the charging aperture of feed pipe 3 respectively, and the air outlet of blower fan is connected with the charging aperture of feed pipe 3.

Need to prove, the utility model provides such enlightenment, when three kinds of materials need mix, can increase by cover the 3rd hopper and the 3rd charging gear, and then the third material dosing is delivered to feed pipe, it can reach mixed uniformly purpose equally.Blade size and corresponding feed opening size in described each rotating shaft simultaneously can be adjusted the purpose that changes proportioning to reach, and perhaps drive motors drives the proportioning that corresponding rotating shaft can change different material equally by the gear train of different drive ratios.
