Abstract
The utility model discloses a powder feed-in screw rod device for a bag powder injection machine, which comprises a powder feed-in screw rod (2) and a forming tube (3), wherein the powder feed-in screw rod (2) is arranged in the forming tube (3), and the outer edge of a helical blade of the powder feed-in screw rod (2) is matched with the inner wall of the forming tube (3); and a plurality of radially-arranged fins (4) are uniformly arranged at the lower end of the powder feed-in screw rod (2). After being additionally arranged at the lower end of the powder feed-in screw rod, the fins play a role of disturbing the powder in the power feed-in process, so as to effectively control the density of the powder between the forming tube and the powder feed-in screw rod and the powder feed-in stability and reducing the density fluctuation of the powder and the fluctuation of the feeding amount, therefore, the stability of net weight is ensured, and the situation that the powder is excessively injected or is not enough is reduced. When the milk powder of 400 g per bag is produced, the net weight scope is controlled from 390-426 g to 393 g-412 g, so that the product qualification ratio is improved.
Description
Technical field
The utility model relates to milk powder in bags production facilities field, particularly relates to the following powder screw device that a kind of bag that is used for milk powder production is annotated the powder machine.
Background technology
At present, a bag notes powder machine that is used for milk powder production is made by German Rovema, its body is provided with hopper, be connected to down powder screw rod and forming tube under the hopper, following powder screw rod is arranged in the forming tube, match with the inwall of forming tube in the helicallobe outer of following powder screw rod, following powder screw rod is rotated by drive mechanism.In the production process, the volume under utilizing between the powder screw pitch turns an angle within a certain period of time and calculates the weight, and following powder screw rod turns an angle, and quantitative milk powder promptly flows down from hopper, forming tube, packs operation then.But because the density of the powder between forming tube and the following powder screw rod can not guarantee to be in a constant state, the stability that calculates the weight is not high, powder net weight range of control inaccuracy, as produce the milk powder of every bag of 400g, and its net weight range of control is in 390 ~ 426g, and product quality is not high.
Therefore, the bag that provides that a kind of net weight range of control is accurate, product quality is high annotates that the powder screw device becomes the industry technical issues that need to address under the powder machine.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and provides the bag that a kind of net weight range of control is accurate, product quality is high to annotate powder screw device under the powder machine.
The purpose of this utility model is achieved through the following technical solutions:
Provide a kind of bag to annotate powder screw device under the powder machine, include down powder screw rod and forming tube, following powder screw rod is arranged in the forming tube, matches with the inwall of forming tube in the helicallobe outer of following powder screw rod, and the described lower end of powder screw rod down evenly is provided with the fin of several radial arrangement.
Described fin radially is arranged on down the lower end of powder screw rod.
Match with the inwall of forming tube in the outer end of described fin.
The number of described fin is 9.
The number of described fin is 12.
Described fin is arranged on the periphery of a ring, and ring is by the lower end of fixed by nut at following powder screw rod.
The cross-sectional plane of described fin is a rectangle.
The beneficial effects of the utility model: the utility model is after powder screw rod lower end increases fin down, fin plays the effect of disturbance powder during following powder, the density that can be controlled to the powder between type tube and the following powder screw rod effectively reaches the stability of powder down, reduced the fluctuation of the density fluctuation and the amount of feeding of powder, thereby guaranteed the stable of net weight, reduced excessive notes powder or not enough situation.As produce the milk powder of every bag of 400g, the net weight range of control reaches 393g ~ 412g by 390 original ~ 426g, has improved product quality.
Description of drawings
Utilize accompanying drawing that utility model is described further, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to the following drawings.
Fig. 1 is the structural representation that bag is annotated powder screw device under the powder machine.
Fig. 2 is the structural representation that nine fins are arranged on the ring periphery.
Fig. 3 is the structural representation that 12 fins are arranged on the ring periphery.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, bag described in the utility model is annotated powder screw device under the powder machine, is arranged on the hopper 1 outlet below that bag is annotated powder machine body.Following powder screw device includes down powder screw rod 2 and forming tube 3, forming tube 3 is connected on below hopper 1 outlet, following powder screw rod 2 is arranged in the forming tube 3, matches with the inwall of forming tube 3 in the helicallobe outer of following powder screw rod 2, and following powder screw rod 2 is rotated by drive mechanism.Produce at present that the powder screw rod turns an angle, quantitative milk powder promptly flows down from hopper, forming tube, packs operation then.The described lower end of powder screw rod 2 down evenly is provided with the fin 4 of several radial arrangement.Described fin 4 is preferably the lower end that radially is arranged on down powder screw rod 2.Match with the inwall of forming tube 3 in the outer end of described fin 4, the cross-sectional plane of described fin 4 is a rectangle.During following powder, fin 4 can play the effect of disturbance powder, and the density that can be controlled to the powder between type tube and the following powder screw rod effectively reaches the stability of powder down, has reduced the fluctuation of the density fluctuation and the amount of feeding of powder, thereby guaranteed the stable of net weight, reduced excessive notes powder or not enough situation.The number of described fin 4 is 9, also can be 12.Described fin 4 is arranged on the periphery of a ring, and ring is convenient to the dismounting of fin 4 like this by the lower end of fixed by nut at following powder screw rod 2.
The utility model is produced the milk powder of every bag of 400g through the actual production experiment, and its net weight range of control reaches 393g ~ 412g by 390 original ~ 426g, has improved product quality.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
