During the injection, it is easy to have unsmooth discharge, resulting in a blocking phenomenon. Moreover, due to the large resistance during the advancement of the valve body and the valve stem and the frequent occurrence of blocking phenomena, when the valve stem has a blocking phenomenon, the force is uneven and the internal stress surges, resulting in easy damage to the valve stem and the valve body. Summary of the Invention

[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the drawings.

[0019] As Figure 1-11 shown, a high-viscosity material filling mechanism includes: A filling cylinder 1, which is connected to the material barrel; A protective shell 2, which is fixedly arranged at the top of the perfusion cylinder 1, and a driving mechanism is arranged inside the protective shell 2; A piston cylinder 9, which is arranged at the top of the perfusion cylinder 1, and a piston 8 driven to reciprocate by a driving mechanism is arranged inside the piston cylinder 9; A perfusion nozzle 3, which is communicatively arranged at the discharge port of the perfusion cylinder 1, and an air cavity is formed inside the wall of the perfusion nozzle 3, and the air cavity is communicated with the piston cylinder 9; Elastic members 6, which are arranged in an array on the inner wall of the perfusion nozzle 3, the inside of the elastic members 6 is provided with a cavity and is communicated with the air cavity, and the piston 8 reciprocates to adjust the air pressure inside the cavity so that the elastic members 6 are deformed; The elastic member 6 includes an elastic arc plate 11 in contact with the material. When the air pressure in the air cavity expands, the elastic arc plate 11 bulges and deforms towards the material direction. When the air pressure in the air cavity contracts, the elastic arc plate 11 depresses and deforms towards the air cavity direction, so as to achieve bionic breathing-type dynamic response.

[0020] Specifically, the material barrel is communicatively connected with the perfusion cylinder 1 and the pressure cylinder through a three-way pipeline. During perfusion, the first valve at the discharge port of the material barrel and the second valve arranged on the intake pipe of the pressure cylinder are opened, and the air cylinder is started to drive the pressure block arranged inside the pressure cylinder to move towards the air cylinder, so that the inside of the pressure cylinder is in a negative pressure state, and the material in the material barrel is pumped into the horizontally arranged main pipeline of the three-way pipeline for temporary storage through the three-way pipeline. Then the first valve is closed, and the third valve arranged at the feed pipe of the perfusion cylinder 1 is opened, and the air cylinder is started to drive the pressure block to move in the reverse direction, so as to push the material temporarily stored in the horizontally arranged main pipeline of the three-way pipeline into the perfusion cylinder 1, thereby realizing quantitative material taking.

[0021] Further, during perfusion, the hydraulic rod 4 fixedly installed at the top of the protective shell 2 is started, so as to drive the valve rod 7 at the output end of the hydraulic rod 4 to move towards the perfusion cylinder 1, thereby driving the valve body 10 fixedly connected to the end of the valve rod 7 to move synchronously, so as to push the material in the perfusion cylinder 1 out along the perfusion nozzle 3 for perfusion.

[0022] Furthermore, due to the high viscosity of the material, it has high stickiness, low fluidity, and strong adhesion. When the valve stem 7 drives the valve body 10 to push the material out along the filling nozzle 3, since the pipe diameter of the filling nozzle 3 is small, when the high-viscosity material passes through the narrow space, due to the adhesion of the material to the inner wall of the filling nozzle 3 and the intermolecular force during the flow of the material, the resistance during pushing the material is large. During the injection process, it is easy to have unsmooth discharging, resulting in a jamming phenomenon. Moreover, due to the large resistance during the advancement of the valve body 10 and the valve stem 7 and the frequent occurrence of jamming phenomena, when the valve stem 7 has a jamming phenomenon, the force is uneven and the internal stress surges, which easily causes damage to the valve stem 7 and the valve body 10. Therefore, an air cavity communicating with the piston cylinder 9 is opened in the inner wall of the filling nozzle 3 and elastic members 6 are arranged in an array on the inner wall of the filling nozzle 3. When the valve stem 7 drives the valve body 10 to push the material out along the filling nozzle 3, the driving mechanism is synchronously started to drive the piston rod arranged on the top of the piston 8 to penetrate through the top of the piston cylinder 9 and reciprocate along the central axis direction of the piston cylinder 9, thereby driving the piston 8 to reciprocate in the piston cylinder 9, thereby adjusting the internal air pressure of the piston cylinder 9. During the reciprocating movement of the piston 8 in the piston cylinder 9, the following deformation occurs to the elastic member 6: When the piston 8 moves from the top of the piston cylinder 9 to the bottom in the piston cylinder 9, the piston 8 adjusts the internal air pressure of the piston cylinder 9 to be compressed, and squeezes the gas in the piston cylinder 9 into the air cavity opened in the inner wall of the filling nozzle 3 through the connecting pipe 5. As the gas is continuously introduced into the air cavity, the air pressure in the air cavity gradually increases, and thus, through the through hole communicated with the cavity of the elastic member 6, the gas is introduced into the cavity of the elastic member 6. As the gas is continuously introduced into the elastic member 6, the internal air pressure of the elastic member 6 continuously increases, thereby causing the elastic member 6 to be inflated and deformed. Since the side of the elastic member 6 in contact with the material is the elastic arc plate 11 and the rest of the parts are rigid structures, when the elastic member 6 is inflated and deformed, as the internal air pressure of the elastic member 6 continuously increases, the elastic arc plate 11 deforms from being concave towards the cavity to being convex towards the material, thereby performing a micro radial extrusion on the material in the flow channel of the filling nozzle 3.

[0023] When the piston 8 moves from the bottom to the top of the piston cylinder 9, the piston 8 adjusts the air pressure inside the piston cylinder 9 to be negative pressure, and draws the air in the air chamber back into the piston cylinder 9 through the connecting pipe 5. As the gas in the air chamber is continuously drawn away, the air pressure in the air chamber gradually decreases to a negative pressure state. Thus, through the through-hole provided for communication with the cavity of the elastic member 6, the gas in the cavity of the elastic member 6 is drawn back into the air chamber. As the gas inside the elastic member 6 is drawn away, the air pressure inside the elastic member 6 continuously decreases, causing the elastic member 6 to contract and deform by pumping air. Since one side of the elastic member 6 in contact with the material is the elastic arc plate 11, and the rest are rigid structures, when the elastic member 6 contracts and deforms, as the air pressure inside the elastic member 6 continuously decreases, and under the action of the self-restoring deformation of the elastic arc plate 11, the elastic arc plate 11 bulges from the material direction and restores deformation to concave towards the cavity direction.

[0024] Thus, through the precise coordination of the positive and negative pressures above, the elastic arc plate 11 repeatedly deforms by concave and convex, so that during perfusion, the inner wall of the perfusion nozzle 3 in contact with the material realizes bionic breathing-like dynamic response. By alternately driving micro mechanical vibrations with positive and negative pressures, the adhesion layer attached to the wall of the perfusion nozzle 3 is peeled off, reducing the adhesion between the material and the wall of the perfusion nozzle 3, thereby reducing the resistance when pushing the material, effectively avoiding the occurrence of jamming phenomena, making the material perfusion smoother, thus avoiding uneven stress on the valve stem 7, resulting in a sharp increase in internal stress, effectively protecting the valve stem 7 and the valve body 10, and extending the service life of the valve stem 7 and the valve body 10.

[0025] Further, a rubber layer is provided at the edge of the valve body 10 to enable the valve body 10 to generate adaptive deformation when moving with the elastic member 6. It should be noted that the above driving mechanism can be an electric push rod driving the piston 8 to reciprocate along the central axis direction of the piston cylinder 9, or a motor driving a lead screw to drive the piston 8 to reciprocate along the central axis direction of the piston cylinder 9, or other well-known technical means in the art to achieve the reciprocating movement of the piston 8 along the central axis direction of the piston cylinder 9.

[0026] As a further embodiment provided by the present invention, the elastic member 6 is arranged in an arc plate shape, and splicing blocks and splicing grooves are provided on the side edges, and a plurality of elastic members 6 are spliced to achieve full coverage of the inner wall of the perfusion nozzle 3.

[0027] Specifically, on the two side edges of the elastic member 6 along the horizontal direction, one side edge is fixedly provided with a splicing block, and the other side is provided with a splicing groove, so that two adjacent elastic members 6 along the horizontal direction are spliced, so that the elastic members 6 are spliced into a complete ring around the inner wall of the perfusion nozzle 3 at the corresponding position and cover the inner wall of the perfusion nozzle 3 in this area.

[0028] Furthermore, on both vertical sides of the elastic member 6, a splicing block is fixedly arranged on one side, and a splicing groove is formed on the other side. Thus, multiple elastic members 6 spliced into a ring are spliced along the vertical direction of the inner wall of the pouring nozzle 3, so that the elastic member 6 is spliced to cover the entire inner wall of the pouring nozzle 3, thereby achieving full coverage of the inner wall of the pouring nozzle 3, avoiding large gaps between adjacent elastic members 6, resulting in material adhesion in the gaps and being unable to be discharged completely, affecting the accuracy of the discharge amount. Thus, under the condition of ensuring the accuracy of the discharge amount, full-coverage micro-mechanical vibration of the tube wall of the pouring nozzle 3 is realized through alternating positive and negative pressure driving, so as to achieve full-angle dead-angle-free peeling of the adhesion layer on the tube wall of the pouring nozzle 3, reduce the adhesion force between the material and the tube wall of the pouring nozzle 3, thereby reducing the resistance when pushing the material, effectively avoiding the occurrence of jamming phenomena, making the material pouring smoother, thereby avoiding uneven force on the valve stem 7, resulting in a sharp increase in internal stress, effectively protecting the valve stem 7 and the valve body 10, and extending the service life of the valve stem 7 and the valve body 10.

[0029] As a further embodiment provided by the present invention, the elastic arc plate 11 bulges and deforms towards the material direction, and a V-shaped gap is formed between the edges of adjacent elastic arc plates 11, and the cross-section of the material passage becomes smaller.

[0030] Specifically, by splicing the elastic members 6 to achieve full coverage of the inner wall of the pouring nozzle 3, when the elastic member 6 is inflated and deformed, since the side of the elastic member 6 in contact with the material is the elastic arc plate 11, and the rest of the parts are rigid structures, so when the elastic member 6 is inflated and deformed, as the internal air pressure of the elastic member 6 continuously increases, the elastic arc plate 11 deforms from being concave towards the cavity direction to bulging towards the material direction, thereby performing a micro radial extrusion on the material in the flow channel of the pouring nozzle 3, and forming a V-shaped gap at the splicing position between two adjacent elastic arc plates 11. As the elastic arc plate 11 deforms from being concave towards the cavity direction to bulging towards the material direction, the material in the V-shaped gap is squeezed from both sides of the side of the V-shaped gap towards the middle, and the included angle between the V-shaped gaps gradually becomes smaller, so that the material in the V-shaped gap is squeezed towards the middle of the pouring nozzle 3, further avoiding the material being stuck in the V-shaped gap and affecting the discharge amount.

[0031] Furthermore, by splicing the elastic members 6 to achieve full coverage of the inner wall of the pouring nozzle 3, as the elastic arc plate 11 deforms from being concave towards the cavity direction to bulging towards the material direction, the cross-sectional area of the material passage of the pouring nozzle 3 becomes smaller. According to the principle that the flow rate is small at the large cross-section and large at the small cross-section, the material in the pouring nozzle 3 is squeezed to accelerate the flow, further making the material discharge smoother, further avoiding the occurrence of jamming phenomena, and improving the accuracy and efficiency of pouring.

[0032] As a further embodiment provided by the present invention, the elastic arc plate 11 deforms in a concave shape towards the air cavity direction, and the cross-section of the material passage becomes larger.

[0033] Specifically, the elastic member 6 is spliced ​​to achieve full coverage of the inner wall of the filling nozzle 3, and the elastic member 6 is evacuated and shrinks and deforms. Since the side of the elastic member 6 that contacts the material is the elastic arc plate 11, and the rest of the parts are rigid structures, when the elastic member 6 shrinks and deforms, as the air pressure inside the elastic member 6 continues to decrease, and under the action of the elastic arc plate 11 restoring its own deformation, the elastic arc plate 11 recovers and deforms from being convex in the direction of the material to being concave in the direction of the cavity, thereby increasing the cross-sectional area of ​​the material channel of the filling nozzle 3, thereby forming local turbulence, removing particle deposition, and further reducing the adhesion of the material.

[0034] Furthermore, by fully covering the equivalent local turbulence, a dead angle is achieved to prevent the material from adhering to the inner wall of the filling nozzle 3, further improving the filling effect and the smoothness of the discharge. By the continuous protrusion and depression of the elastic arc plate 11, a surrounding vibration and a local vortex are formed on the inner wall of the filling nozzle 3, and a shear layer is formed by the sudden change of the flow channel cross-sectional area to generate a flow velocity difference, which effectively eliminates bubbles in the discharge process and further improves the filling effect.

[0035] As a further embodiment of the present invention, a rubber pad is arranged in the inner cavity of the elastic member 6 .

[0036] Specifically, a rubber pad is provided in the cavity of the elastic member 6 to elastically support the interior of the elastic member 6, and the elastic arc plate 11 is elastically supported by the rubber pad to avoid excessive deformation of the elastic arc plate 11 when the elastic arc plate 11 is squeezed during the movement of the piston 8.

[0037] As a further embodiment of the present invention, a unit cavity connected to the air cavity is opened in the middle of the rubber pad, and the unit cavity and the elastic arc plate 11 form a regular hexagonal honeycomb cavity, and a steel plate is fixedly arranged on the inner wall of the unit cavity.

[0038] Furthermore, a unit cavity connected to the air cavity is opened in the middle of the rubber pad, and the unit cavity and the elastic arc plate 11 constitute a regular hexagonal honeycomb cavity. A steel plate is fixedly arranged on the inner wall of the unit cavity. By inflating or exhausting air into the honeycomb cavity, the elastic member 6 is inflated and deformed or exhausted and contracted, so that the elastic arc plate 11 undergoes a convex deformation or a concave deformation, thereby realizing a bionic breathing-like dynamic response. As the gas continuously alternates in and out of the honeycomb cavity, the steel plate resonates and transmits the vibration to the elastic arc plate 11, thereby forming a vibration shear between the elastic arc plate 11 and the material, further reducing the adhesion between the material and the elastic arc plate 11, and improving the fluidity of the material, thereby making the discharge smoother and further improving the infusion effect.

[0039] As a further embodiment of the present invention, a gap is provided between the elastic arc plate 11 and the surface of the rubber pad on one side close to the material.

[0040] Specifically, a gap is provided between the elastic arc plate 11 and the surface of the rubber pad close to the material, so as to provide a deformation space for the elastic arc plate 11.

[0041] As a further embodiment provided by the present invention, elastic microspheres are arranged in the unit cavity, and the diameter of the elastic microspheres is larger than the diameter of the air inlet of the unit cavity.

[0042] Specifically, by arranging elastic microspheres in the unit cavity, since the unit cavity and the elastic arc plate 11 form a regular hexagonal honeycomb-shaped cavity, a steel plate is fixedly arranged on the inner wall of the unit cavity. As the honeycomb-shaped cavity is inflated or deflated, the elastic member 6 is inflated and expanded or deflated and contracted, so that the elastic arc plate 11 bulges or concaves, and as the gas continuously alternates in and out of the honeycomb-shaped cavity, the elastic microspheres continuously obtain speed and move in the honeycomb-shaped cavity, and rebound irregularly in the honeycomb-shaped cavity. The vibration wave is conducted to the flow channel through the honeycomb wall, the movement track of the small balls covers the surface of the cavity, and by simulating and optimizing the shape of the honeycomb cavity, the collision of the small balls presents chaotic characteristics to realize irregular rebound movement. Through the gradient depth of the hexagonal unit, the random collision energy is converted into directional mechanical waves through the chaotic cavity design to realize the directional aggregation of energy. The vibration mechanical wave is conducted to the flow channel and the material through the honeycomb wall, further improving the shear rate, effectively reducing the adhesion of the material and the viscosity between the material molecules, so that the material flows more smoothly, further improving the perfusion efficiency and perfusion effect, and effectively reducing the material residue.

[0043] As a further embodiment provided by the present invention, a gear is rotatably arranged in the protective shell 2, and a transmission connection is provided between the edge of the gear and the piston 8. The rotation of the gear drives the piston 8 to reciprocate in the piston cylinder 9 to adjust the internal air pressure of the piston cylinder 9.

[0044] As a further embodiment provided by the present invention, a rack is movably arranged in the protective shell 2 along the moving direction of the piston 8, and the rack is meshed with the gear.

[0045] Specifically, the rack is fixedly connected to the valve rod 7. When the valve rod 7 moves, the rack moves synchronously with the valve rod 7, thereby driving the gear to rotate synchronously. Thus, the piston rod is driven to reciprocate through the hinge rod hinged between the edge of the gear and the piston rod of the piston 8, thereby driving the piston 8 to reciprocate in the piston cylinder 9. Thus, there is no need for an additional driving source to drive the piston 8 to reciprocate, thereby saving the manufacturing cost and the failure rate, and being able to make the piston 8 respond synchronously when squeezing and discharging materials.

[0046] Only certain exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
