Abstract

The invention provides an adaptive three-roller machine used for grinding liquid daily chemicals. The adaptive three-roller machine comprises a machine body, wherein a discharge bucket is arranged in front of the machine body, three press rollers which lean against one another are arranged above the machine body, the three press rollers are respectively driven by a driving motor by virtue of rotating shafts arranged at the end parts of the three press rollers, the rotating shaft of each press roller is pivoted with a bearing movably connected with the machine body, an electromagnet is arranged in each press roller, and each electromagnet is electrically connected with a controller. The three-roller machine has the advantages that the position of each press roller can be adjusted according to the heat expansion of the press roller so as to keep inter-roller pressure, no complicated feedback circuit is used, the structure is simple and the performance is stable.

Description

A kind of self adaptation three-roller

Technical field

The present invention relates to a kind of mechanical grinding device, especially, is a kind of three-roller that is used for the grinding liquid cosmetics of everyday use, comprises three by motor-driven pressure roller.

Background technology

[0002] present cosmetics of everyday use is of a great variety; Wherein bigger one type belongs to the liquid cosmetics of everyday use; Like shampoo, shower cream, hand cleanser, washing agent or the like, such cosmetics of everyday use needs uniformity requirement in process of production usually, in order to improve the uniformity of liquid cosmetics of everyday use; Usually need to stir through mixer earlier, handle by three-roller then.

Present three-roller mainly comprises body and by three pressure rollers of drive motor drives, and near, reverse rotation, viscous liquid flows through between each pressure roller each pressure roller, can realize the grinding to liquid small particles or little solid piece each other; According to the difference of the required uniformity, can through regulate parts regulate between three pressure rollers near degree, normally, lean on tightly more, then grinding precision is high more, but roll gap pressure is bigger, energy consumption is bigger, and it is dead that pressure roller is expanded; Generally speaking, pressure roller inside also is provided with cooling water recirculation system, and the cooling water circulation rate that control feeds can be controlled the heat expansion degree of pressure roller, can realize regulating between pressure roller near degree; Yet above-mentioned regulative mode all needs a series of feedback circuits to be achieved, and the adjusting program is complicated, and occurs mistake easily.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of self adaptation three-roller, this kind three-roller can expand with the heating of pressure roller and regulate each pressure roller position automatically, thereby keeps roll gap pressure, need not complicated feedback circuit, and is simple in structure, stable performance.

The technical solution adopted for the present invention to solve the technical problems is: this self adaptation three-roller comprises body; Said body the place ahead is provided with discharge bucket; Said body top is provided with three pressure rollers close to each other, and said three pressure rollers rely on the rotating shaft of end driven by drive motors separately; The rotating shaft of each said pressure roller is articulated on the bearing that flexibly connects with said body; Each said pressure roller inside is provided with electromagnet; Each said electromagnet and controller are electrically connected.

As preferably, said pressure roller is made up of hollow iron pipe, its chrome-faced; The inwall of each said pressure roller is provided with strain gauge, is used for sensing pressure roller body stress, the reaction pressure roll gap pressure, and said strain gauge is electrically connected said controller.

As preferably, said electromagnet is made up of iron core and the coil that is around on the iron core, and said iron core is straight circular cylinder type, is fixed on the axis of said pressure roller.

As preferably, the movable connection method between said bearing and the said body is: said bearing below is provided with slide block, and said body and said bearing cooperation place are provided with chute, said slide block can be in said chute slip before and after the straight line.

Beneficial effect of the present invention is: this self adaptation three-roller in use; According to needing and regulating the electromagnet current in each said pressure roller through said controller; Thereby regulate the gravitation between each pressure roller; Under the interaction of deformation elastic force between gravitation and pressure roller, regulate the position of each pressure roller on said body by said bearing; Thus, only need to regulate each electromagnet current, can realize the pressure adjustment between each pressure roller through controller; Satisfy various grinding demands, and, according to the reaction force principle; Pressure between pressure roller equals the gravitation of each pressure roller all the time; Do not receive the influence of pressure roller thermal expansion, therefore need not water-cooling system, the dead problem that expands also can not take place in pressure roller; This self adaptation three-roller need not complicated reponse system, and is simple in structure, stable performance.

Fig. 1 is the structural representation of an embodiment of this self adaptation three-roller;

Fig. 2 is the sectional view of pressure roller among Fig. 1 embodiment;

Fig. 3 is the explosive view of pressure roller and body mating part among Fig. 1 embodiment.

Among the figure: 1, three pressure rollers; 10, hollow iron pipe; 11, electromagnet; 13, chromium; 2, bearing; 21, slide block; 3, chute; 4, body; 40, discharge bucket.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In the embodiment shown in fig. 1; This self adaptation three-roller comprises body 4, and said body 4 the place aheads are provided with discharge bucket 40, and said body top is provided with three pressure rollers 1 close to each other; Said three pressure rollers 1 rely on the rotating shaft of end to receive drive motors (non-improvement part separately; Not shown) drive, the type of drive that is adopted can be the band transmission to have bigger adjustable space; The rotating shaft of each said pressure roller 1 is articulated on the bearing that flexibly connects with said body 4; Specifically as shown in Figure 3: said bearing 2 belows are provided with slide block 21; Said body and said bearing 2 cooperation places are provided with chute 3, and said slide block 21 can slide before and after straight line in said chute 3.

Like Fig. 1, shown in Figure 2, said pressure roller 1 is made up of hollow iron pipe 10, its chrome-faced 13; Each pressure roller 1 inside is provided with electromagnet 11; Said electromagnet 11 is made up of iron core and the coil that is around on the iron core, and said iron core is straight circular cylinder type, is fixed on the axis of said pressure roller 1; Each said electromagnet 11 is electrically connected with controller (not shown).

Above-mentioned self adaptation three-roller, the inwall of each said pressure roller 1 can also be provided with strain gauge, is used for the body stress of sensing pressure roller 1, the reaction pressure roll gap pressure, said strain gauge is electrically connected said controller.

Above-mentioned self adaptation three-roller in use; According to needing and regulating electromagnet 11 electric currents in each said pressure roller 1 through said controller; Thereby regulate the gravitation between each pressure roller 1; Under the interaction of gravitation and 1 deformation elastic force of pressure roller, regulate the position of each pressure roller 1 on said body 4 by said bearing 2; Thus, only need to regulate each electromagnet 11 electric current, can realize the pressure adjustment of 1 of each pressure roller through controller; Satisfy various grinding demands, and, according to the reaction force principle; The pressure that pressure roller is 1 equals the gravitation of each pressure roller 1 all the time; Do not receive the influence of pressure roller 1 thermal expansion, therefore need not water-cooling system, the dead problem that expands also can not take place in pressure roller 1; This self adaptation three-roller need not complicated reponse system, and is simple in structure, stable performance.
