A kind of pressure setting
Technical field
The utility model relates to food processing field, is specifically related to a kind of pressure setting.
Background technology
Along with the development of society, the mankind improve constantly various food requirement, and demand continues to increase, and social industry divides the continuous refinement of worker, require the food-processing industry industrialization to produce, and promptly producing in enormous quantities is the developing direction of present stage food enterprise.Bean curd contains very high protein, and 10 multiple beneficial such as lower fat and iron, calcium are in the mineral element and the multivitamin of health.And bean curd has, and " beneficial gas and taste in wide, dissipate-swelling are full, the heat that disappears is loose blood etc., and health care is worth.As a kind of traditional food, the manufacturing of bean curd all is a family workshop type, and manufacturing equipment falls behind, and sanitary condition is relatively poor, and its health and quality safety mainly lean on practitioner's quality to control, and have the hidden danger of health and safe mass; And existing its pressing structure more complicated of gravity type press filtration bean curd machine, cost is higher, and processing bean curd is inconvenient.
Summary of the invention
The technical problem that the utility model solves provides a kind of pressure setting, and its simple and stable structure and cost are lower, are user-friendly to.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pressure setting comprises motor, shelf and guide post; Be fixed with output shaft on the motor, shelf is provided with the hole, and guide post passes the hole on the shelf; Wherein, the output shaft of described motor is connected with the pressing structure that is used to suppress the food moulding, and described pressing structure is connected with shelf; The output shaft rotating band dynamic pressure system structure motion of motor, pressing structure drive shelf makes it move along guide post.
Attach on the described motor reducing motor is arranged.The rotating ratio of motor output shaft is higher, through the effect of reducing motor, has reduced the output speed of motor.
Described pressing structure comprises shaft coupling, feed screw nut and screw mandrel, and shaft coupling one end is connected with the output shaft of motor, and the other end is connected with screw mandrel; External screw thread and feed screw nut that screw mandrel is provided with feed screw nut's screw-internal thread fit can move on screw mandrel.Thereby described feed screw nut moves up at screw mandrel and drives shelf and move up along guide post; When shelf moves down along guide post, can drive its whereabouts or drive its whereabouts through guide thing decline shelf deadweight whereabouts or by spring its whereabouts of pulling or feed screw nut by magnet.
Shaft coupling is that two axles that are used for connecting in the different institutions make it common rotation to transmit the machine components of moment of torsion.The mode of screw mandrel transmission mainly is that the output shaft of motor rotates; Driving screw mandrel through shaft coupling rotates; Because external screw thread and feed screw nut's screw-internal thread fit on the screw mandrel, the feed screw nut can move up and down on screw mandrel, and the shelf that is fixedly connected with the feed screw nut will move up and down along guide post.
Preferably, pressing structure can be belt transmission, comprises driving wheel, driving belt and driven pulley, and driving wheel and driven pulley are located at the driving belt two ends respectively, and driving wheel is fixed on the output shaft of motor and driving wheel drives driven pulley through driving belt and rotates.Described lower shelves is provided with fairlead, and the fairlead other end is fixed on the driving belt, and driving belt moves through fairlead drive shelf and moves up along guide post; When shelf moves down along guide post, can drive its whereabouts or drive its whereabouts through guide thing decline shelf deadweight whereabouts or by spring its whereabouts of pulling or fairlead by magnet.
Described shelf is a translation frame moving up and down.Can guarantee the object horizontal positioned on the shelf.
Compared with prior art, beneficial effect is: the output shaft of the motor of the utility model is connected with pressing structure, and described pressing structure is connected with shelf, and the output shaft rotating band dynamic pressure system structure motion of motor, pressing structure drive shelf makes it move along guide post.Adopt this structure can make overall structure simple and stable and cost lower, be user-friendly to and realize automation control.

The specific embodiment
Embodiment one
As shown in Figure 1, a kind of pressure setting comprises motor 10, shelf 20 and guide post 30; Be fixed with output shaft on the motor 10, shelf 20 is provided with the hole, and guide post 30 passes the hole on the shelf 20; Wherein, the output shaft of described motor 10 is connected with the pressing structure that is used to suppress the food moulding, and described pressing structure is connected with shelf 20; The output shaft rotating band dynamic pressure system structure motion of motor 10, pressing structure drive shelf 20 makes it move along guide post 30.Attach on the motor 10 reducing motor is arranged.
Pressing structure comprises shaft coupling 1, feed screw nut 2 and screw mandrel 3, and shaft coupling 1 one ends are connected with the output shaft of motor 10, and the other end is connected with screw mandrel 3; External screw thread and feed screw nut 2 that screw mandrel 3 is provided with feed screw nut's 2 screw-internal thread fit can move on screw mandrel 3.Thereby described feed screw nut 2 moves up at screw mandrel 3 and drives shelf 20 and move up along guide post 30; When shelf 20 moves down along guide post 30, can drive its whereabouts or drive its whereabouts through shelf 20 deadweight whereabouts or by spring its whereabouts of drive or feed screw nut 2 by magnet.
Operation principle is that the output shaft of motor 10 rotates; Driving screw mandrel 3 through shaft coupling 1 rotates; Because external screw thread and feed screw nut's 2 screw-internal thread fit on the screw mandrel 3; Feed screw nut 2 can move up and down on screw mandrel 3, thereby feed screw nut 2 moves up at screw mandrel 3 and drives shelf 20 and move up along guide post 30 during rising.During the whereabouts, when shelf 20 moves down along guide post 30, can drive its whereabouts or drive its whereabouts through shelf 20 deadweight whereabouts or by spring its whereabouts of drive or feed screw nut 2 by magnet.
Embodiment two
As shown in Figure 2; Pressing structure can comprise driving wheel 4, driving belt 5 and driven pulley 6; Driving wheel 4 is located at driving belt 5 two ends respectively with driven pulley 6, and driving wheel 4 is fixed on the output shaft of motor 10 and driving wheel 4 drives driven pulleys 6 through driving belt 5 and rotates.Shelf 20 bottoms are provided with fairlead, and the fairlead other end is fixed on the driving belt 5, and driving belt 5 moves through fairlead drive shelf 20 and moves up along guide post 30; When shelf 20 moves down along guide post 30, can drive its whereabouts or drive its whereabouts through shelf 20 deadweight whereabouts or by spring its whereabouts of drive or fairlead by magnet.
Operation principle is that the output shaft of motor 10 rotates 4 rotations of drive driving wheel, and driving wheel 4 drives driven pulleys 6 through driving belt 5 and rotates, and during rising, driving belt 5 moves through fairlead drive shelf 20 and moves up along guide post 30; During the whereabouts, can drive its whereabouts or drive its whereabouts through guide thing decline shelf 20 deadweight whereabouts or by spring its whereabouts of drive or fairlead by magnet.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the utility model principle, can do the improvement of some suitable actual conditions to the technical scheme of utility model.Therefore, the protection domain of the utility model is not limited thereto, and those of skill in the art are any to be included within the utility model protection domain based on non-material change on the utility model technical scheme.
