Multistage gear-driven container for ejecting paste material

Abstract

The present invention relates to a multistage gear-driven container for ejecting a paste material, which can control the ejection of paste by means of the operation of multistage drive gears so as to enable a stable ejection control, controls the ejection of the paste by means of the operation of the multistage drive gears, thereby exhibiting an effect of being able to perform more stable driving than the conventional lift screw, and forms an assembly-type structure having a removable container body, thereby providing an advantage of replacing only the container body storing paste products and enabling a lower driver to be reused.

1 . A multistage gear-driven container for ejecting a paste material, comprising:
 a container body ( 10 ) having an inner space configured to accommodate a paste material.   a main body pressing plate ( 20 ) lifted and lowered in the container body ( 10 );   a gear driver ( 30 ) detachably coupled to a lower portion of the container body ( 10 ); and   a motor driver ( 40 ) installed under the gear driver ( 30 ) and including a driving motor ( 41 ) configured to transmit a driving force to a drive gear ( 31 ) formed in the gear driver ( 30 ).   
     
     
         2 . The multistage gear-driven container of  claim 1 , wherein the container body ( 10 ) includes:
 a partition wall ( 11 ) which divides an inner space thereof into a plurality of spaces; and   the main body pressing plate ( 20 ) lifted and lowered in each of the divided spaces of the container body ( 10 ).   
     
     
         3 . The multistage gear-driven container of  claim 2 , wherein the gear driver includes:
 the drive gear ( 31 ) formed in the gear driver ( 30 );   a driven gear ( 32 ) configured to receive a rotational force from the drive gear ( 31 );   a lower pressing plate ( 33 ) formed above the driven gear ( 32 ) and configured to lift the main body pressing plate ( 20 );   a multistage lifting and lowering gear ( 34 ) in which a plurality of lifting and lowering gears having different diameters are connected by screw-coupling to receive the rotational force from the driven gear ( 32 ) and to lift and lower the lower pressing plate ( 33 ), wherein an upper end of a lifting and lowering gear located at a center thereof is fixed to the lower pressing plate ( 33 ); and   an inner housing ( 35 ) configured to support the driven gear ( 32 ) in the gear driver ( 30 ).   
     
     
         4 . The multistage gear-driven container of  claim 3 , wherein:
 a male screw ( 16 ) is formed on an outer surface of the lower portion of the container body ( 10 ); and   a female screw ( 36 ) corresponding to the male screw ( 16 ) is formed in an inner circumferential surface of an upper portion of the gear driver ( 30 ) such that a detachable structure for the container body ( 10 ) and the gear driver ( 30 ) is formed.   
     
     
         5 . The multistage gear-driven container of  claim 4 , wherein:
 the lifting and lowering gears included in the multistage lifting and lowering gear ( 34 ) have a structure in which diameters (d) of the lifting and lowering gears gradually increase from a bottom lifting and lowering gear to a top lifting and lowering gear;   an outer screw thread ( 34   a ) is formed on an outer wall surface of each of the lifting and lowering gears;   an inner screw thread ( 34   b ) is formed on an inner wall surface of only an upper end portion of each of the lifting and lowering gears;   a stopper ( 34   c ) configured to prevent deviation is formed at a lower portion of each of the lifting and lowering gears; and   a lower screw thread ( 32 ′) screw-coupled to the multistage lifting and lowering gear ( 34 ) is formed on an inner wall surface of the driven gear ( 32 ).   
     
     
         6 . The multistage gear-driven container of  claim 5 , wherein a protrusion insertion groove ( 34   a ′) into which a lower protrusion ( 33 ′), which protrudes from a center of a bottom surface of the lower pressing plate ( 33 ), is fixedly inserted is formed in the lifting and lowering gear located at the center of the multistage lifting and lowering gear ( 34 ). 
     
     
         7 . The multistage gear-driven container of  claim 6 , wherein:
 an elastic spring ( 50 ) configured to elastically support lifting and lowering is formed in the multistage lifting and lowering gear ( 34 );   an insertion groove ( 51 ) into which an upper end of the elastic spring ( 50 ) is inserted and to be supported is formed in the lifting and lowering gear located at the center of the multistage lifting and lowering gear ( 34 );   a guide plate ( 52 ) in a circular plate form is connected to a lower end of the elastic spring ( 50 ); and   a seating groove ( 53 ) in which the guide plate ( 52 ) is seated is formed in a bottom surface of the driven gear ( 32 ).
