Extrusion device for tubes

Abstract

An extrusion device, for tubes, includes: an accommodation member having pushing holes formed through both sides facing each other and a discharge hole formed in the upper end thereof and connected to an internal space thereof; and a pressing member installed inside the internal space and having a pair of pressing bodies arranged symmetrically with each other, each including a compression portion provided on the opposite side of a pushing portion exposed through each pushing hole to discharge contents in the deformable tube accommodated between the compression portions through the discharge hole by pressing of the pushing portions, wherein a plurality of fine adjustment pieces that protrude from the compression surfaces of the compression portions may vary in the degree of elastic deformation according to the pressing force of the pushing portions, thus adjusting the surface of contact with the tube and adjusting the discharge amount of the tube contents.

1 . A tube extrusion device comprising:
 an accommodation member ( 100 ) having pushing holes ( 102 ) formed through both sides facing each other and a discharge hole ( 103 ) formed in the upper end thereof and connected to an internal space ( 101 ) thereof; and a pressing member ( 200 ) installed inside the internal space ( 101 ) of the accommodation member ( 100 ) and having a pair of pressing bodies ( 201 ), which are arranged symmetrically with each other and each of which includes a pushing portion ( 211 ) exposed through each pushing hole ( 102 ) and a compression portion ( 212 ) provided on the opposite side of the pushing portion ( 211 ) and having a plurality of fine adjustment pieces ( 213 ) protruding thereon, wherein a deformable tube (T) accommodated between the pair of pressing bodies ( 201 ) adjust the discharge amount of contents by the fine adjustment pieces ( 213 ) varying contact surfaces thereof through elastic deformation depending on pressing force of the pushing portion ( 211 ),   wherein the bottom of the internal space ( 101 ) has a sliding portion ( 104 ) formed as a V-shaped inclined guide surface, which slopes upward from the center toward both ends, and each pressing body ( 201 ) includes an elastic leg ( 220 ) having a sliding support ( 221 ), which is provided at the lower end thereof and on which the sliding portion ( 104 ) slides, to enable elastic operation, and   wherein the pressing member ( 200 ) is guided downward toward the lower end of the tube (T) along the inclined guide surface of the sliding portion ( 104 ) from both ends toward the center to compress the tube (T).   
     
     
         2 . The tube extrusion device according to  claim 1 , wherein the fine adjustment pieces ( 213 ) are formed on the compression surface of the compression portion ( 212 ) in a linear pattern at predetermined intervals or in a dot-shaped pattern at predetermined intervals. 
     
     
         3 . The tube extrusion device according to  claim 1 , wherein the elastic leg ( 220 ) comprises:
 an intermediate connector ( 222 ) arranged transversely at the middle of the elastic leg ( 220 ); an upper connector ( 223 ) alternately bent on both sides of the intermediate connector ( 222 ); a sliding support ( 221 ) integrally connected above and below the intermediate connector ( 222 ) in a transverse direction; and an upright connector ( 224 ) extending longitudinally from an end portion of the upper connector ( 223 ), and integrally connected to the lower end of the pressing body ( 201 ).
