Abstract
The utility model provides a powder split-charging screw rod which is combined by an inverted tapered helix at the upper part and a column-shaped helix at the lower part. A screw rod stud is one, two or three combinations of a cylinder, a prism, a cone column or a pyramid column. The powder split-charging screw rod can increase the split-charging speed, improve the charging precision, widen the charging range, enhance the adaptability to powder, and ensure the split-charging quality of various kinds of powder.
Description
Technical field
The utility model relates to a kind of powder and divides loading screw, belongs to food, chemical industry, pharmaceutical equipment technical field.
Background technology
The screw racking machine is widely used in the powder packing of industries such as food, chemical industry, pharmacy, improve separate-loading packaging and loading amount precision, enlarge the loading amount scope and to the comformability of powder, the special difference of bigger and easy conglomeration grain of viscosity or flowing power bulk density apparent gravity being differed greatly or the special good and bigger smooth packing of powder of proportion of flowing power, is powder dispensing apparatus problem demanding prompt solution for a long time.The screw type sub packaging machine screw rod of Shi Yonging generally is the equidistant screw rod of cylinder in the market because the unicity of its structure is difficult to satisfy above-mentioned different physical behavior powder and divides reload request accurately at a high speed, can not guarantee the graininess powder in packing not by breakage.Especially run into the special difference of bigger and easy conglomeration grain of viscosity or flowing power and the bulk density apparent gravity differs greatly or flowing power is special good and proportion is big or the special little and very irregular powder that is suspension of powder shape of density, or special hour of loading amount, the packing operation can not be carried out smoothly.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of powder and divides loading screw, to improve separate-loading packaging and loading amount precision, enlarges the loading amount scope and to the comformability of powder with guarantee the packing requirements for quality of various powders.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of powder divides loading screw, and screw rod is that inverted upper cone-type spiral and the combination of bottom cylindricality spiral are provided with; Screw column is wherein a kind of, two or three combination of cylinder, prism, circular cone post or pyramid post.
In the utility model, the limit number of the prism of described screw column or pyramid post is 4,5,6,8 or 12.
In the utility model, the top spiral extension of described screw rod is provided with the involute scraper plate.
In the utility model, the afterbody of the bottom spiral of described screw rod can be made into single head, double end or bull.
In the utility model, be hollow under the described screw rod.
Adopt the beneficial effect that technique scheme produced to be: the technical solution adopted in the utility model can be passed through combined transformation cone-type spiral and cylindricality spiral, cylindrical screw column and prismatic screw column, a number of afterbody, and height of spiral, pitch etc. are made serial profiled screw product; In actual applications,, select different screw rods, with branch packing quality that guarantees powder and the complete machine performance that improves racking machine according to the specific requirement of different powder packing; In industries such as food, chemical industry, pharmacy wide application market is arranged.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
1,2,4, screw column 3, scraper plate 5, inverted upper cone-type spiral 6, bottom cylindricality spiral among the figure:
The specific embodiment
The instantiation that the utility model provides shown in Fig. 1,2, a kind of embodiment that provides among the figure are inverted upper cone- type spiral 5 and 6 combinations of bottom cylindricality spiral.The upper screw post is a pyramid post 1, and the bottom screw column is for being cylinder 4, and profiled screw array mode of the present utility model comprises that also screw column is cylinder, prism, circular cone post, pyramid post and zero wherein a kind of, two or three combination.The limit number of the prism of above-mentioned screw column or awl post is 4,5,6,8 or 12.The afterbody of above-mentioned screw rod can be made into single head, double end or bull.
One of purpose of the utility model array mode is that the volume that powder is passed through diminishes gradually, allows the density of powder strengthen gradually in minute process of assembling and apparent gravity is tending towards homogeneous, so that raising separate-loading packaging and loading amount precision; Two of purpose is prismatic or pyramid cylindricality screw column can be realized the bump function to powder in screw propulsion.Be particularly useful for the powder packing of the bigger and easy conglomeration grain of the special difference of flowing power viscosity; Three of purpose is that cored screw can prevent that the graininess powder is damaged in packing.Except above-mentioned example, in actual applications, the utility model can also be combined as under the epicone cylindricality spiral or be the cylindricality spiral up and down, last pyramid screw column, the following prismatic cylindrical screw column that adds; Or be prismatic screw column up and down; Or upward being conical screw column, the bottom screw column is zero; Or be the pyramid screw column up and down and add cylindrical screw column; Or top is the back taper screw column, and the middle part is positive taper screw column, and the bottom is a cylindrical screw column etc.; Screw rod tail can be made into single head, double end or bull according to actual needs, and spiral height and pitch also can equate or not wait.
With the powder cutting, the utility model also can be provided with involute scraper plate 3 in 5 extensions of the top of screw rod spiral for better.
Foregoing description only proposes as several enforceable technical scheme of the utility model powder packing profiled screw, not as the single limiting condition to its structure itself.
