Extrusion pumping module according to the invention can be carried out as will be described below.

As shown in Figure 3 to 5, the extrusion pumping module according to an embodiment of the present invention may be implemented by combining a plurality of pumping unit 300.

Pumping unit 300 is a plate-like member is provided with a flow hole 314 open in the center, the plate member 310 is formed to be inclined toward one side toward the outside with respect to the flow hole 314, a pair of plates The member 310 is overlapped to form a space therein, and the coupling member 330, the coupling member 330 and the pair of plate members 310 provided to fasten the outer circumference of the pair of plate members 310 to each other. The sealing member 320 may be disposed to be buffered and sealed.

In the pumping unit 300, the space between the pair of plate members 310 is narrowed with each other, and the accommodation accommodated in the inner side is extruded through the flow hole 314, and the space between the pair of plate members 310 is far from the inner side. The space of the space can be widened and the contents can be introduced.

The plurality of pumping units 300 are coupled to each other so that the flow holes communicate with each other to form the pumping module 30.

Hereinafter, each configuration described above will be described in detail.

The pumping unit 300 has a pair of plate members 310 formed to overlap each other, and a space is formed therein.

The space formed inside the pumping unit 300 is exposed to the outside through the flow hole 314 provided in the pair of plate members 310 coupled to each other.

Since the pair of plate members 310 are coupled along the outer circumference, two flow holes 314 may be included in one pumping unit 300, and two flow holes 314 may be disposed opposite to each other. have.

The unit plate member 310 and one plate member 310 are formed by the flow hole 314 through the center, and is a plate-shaped member having a constant inclination toward the outside with respect to the flow hole 314.

Therefore, one surface of the plate member 310 protrudes in a convex shape, and the other surface has a concave shape in a concave shape, as shown in FIG. 3.

When a pair of plate members 310 are coupled to each other adjacent to the outer periphery thereof, respectively, the concave surfaces are coupled to face each other, and thus, the pumping unit 300 to which the pair of plate members 310 are coupled is predetermined inside thereof. Space may be formed.

Each plate member 310 may be implemented in the form of a disc with a flow hole 314 in the center, which is to have a variety of shapes, such as a disc shape, a rectangular plate shape according to the embodiment to which the present invention is applied It may be implemented, in one embodiment of the present invention will be described by way of example in the form of a disc.

In addition, a first elastic section 312 continuously formed around the flow hole 314 in a predetermined width may be further included between the flow hole 314 and the outer circumference of the plate member 310.

The first elastic section 312 may have a modulus of elasticity smaller than the modulus of elasticity of the material of the plate member 310, so that the first elastic section 312 may be more fluidly deformed.

Specifically, the first elastic section 312 may be formed to be a part of the plate member 310 corrugated, which is shown in Figures 3 to 5, the flow hole 314 of the plate member 310 It may be arranged outside the flow hole 314 to form a closed curve surrounding the flow hole 314.

The first elastic section 312 is formed in a corrugated form is provided so that a portion of the plate member 310 is wrinkled has the effect that the deformation can occur more flexibly due to the bending caused by the external force, which is the plate member 310 The pressure is applied to the inner receiving material of the pumping unit 300 and the pumping module 30, which is formed by coupling, and increases the amount of the extruded material through a large volume change per unit time.

As another example, the first elastic section 312 is all made of a metal material having the same elastic modulus of the plate member 310, the relative thickness is formed thicker toward the flow hole 314 and the outer circumference, the flow hole Since the thickness is thinner toward the stop portion between the 314 and the outer periphery, it can be implemented.

At this time, the deformation is more flexible due to the relatively thin thickness, thereby obtaining the same effect as in the case of having a low elastic modulus value in China.

The outer circumference of the plate member 310 may be processed by folding in the direction of the convex surface along the circumference, and the coupling member 330 may be fastened around the outer surface of the folded portion.

In addition, the sealing member 320 may be inserted between the plate member 310 and the coupling member 330 to be fastened together through the fastener 340.

The sealing member 320 is continuously disposed along the outer circumference of the plate member 310, and serves as a buffering role and a sealing role between the plate member 310 and the coupling member 33.

The sealing member 320 may be implemented as a spacer for performing a buffering role and a sealing member for performing a sealing role, which may be implemented in a variety of ways for the cushioning and sealing according to the embodiment to which the present invention is applied. will be.

Coupling member 330 is a thin plate-like member is formed long to the length enough to surround the outer periphery of the plate member 310.

Coupling member 330 may also be implemented in a metal material in one embodiment of the present invention.

In addition, the coupling member 330 may further include a second elastic section 332 which is continuously formed in the left and right directions at the stop portion of the vertical direction when the longitudinal direction is assumed to be the left and right directions.

The second elastic section 332 may be implemented to have an elastic modulus value lower than the inherent elastic modulus value of the coupling member 330, as in the first elastic section 312 described above.

Alternatively, the thickness may be formed thinner than the periphery, and as shown in FIGS. 6 and 7, it may be formed by being folded to protrude a part of the surface toward one surface.

At this time, the coupling member 330 coupled around the outer circumference of the pair of plate members 310 has at least a portion of the second elastic section 332 which is folded and protruded between the outer circumferences of the plate member 310 to be coupled to each other. Can be combined to be inserted without interference.

In another embodiment, the pair of plate members 310 may be bonded to the coupling member 330 around the outer circumference thereof.

Bonding processing may be utilized by fusion welding to heat and melt the metal material, or welding by applying a strong physical pressure, which may be implemented by various welding methods according to the embodiment to which the present invention is applied. .

In addition, the first elastic section 312 of the plate member 310 described above may be provided over the entire region, not a partial section of the plate member 310, as shown in Figure 8, the elastic section 312 ) Is provided over a portion or all sections of the plate member 310 may be appropriately determined and implemented according to the embodiment to which the present invention is applied.

This has the effect that the volume of the internal space can be changed more flexibly in response to external forces in the process of changing the volume of the space provided inside the pumping module 30 is compressed or expanded, this effect is further pumped per unit time It serves to increase the amount of receptacle that can be made.
