Description

Technical Field

[0001] The invention relates to the technical field of material pouring, and in particular to a high-viscosity material pouring mechanism. Background Art

[0002] When high viscosity materials are poured, due to their high viscosity, low fluidity and strong adhesion, when the valve stem drives the valve body to push the material out along the pouring nozzle, due to the small diameter of the pouring nozzle pipe, when the high viscosity material passes through a narrow space, due to the adhesion of the material to the inner wall of the pouring nozzle and the force between molecules when the material flows, the resistance when pushing the material is large. When pushing, the material is easily discharged, resulting in a jamming phenomenon. Moreover, due to the large resistance of the valve body and valve stem during the advancement process and frequent jamming, the valve stem is unevenly stressed when jamming occurs, and the internal stress surges, which makes the valve stem and valve body easily damaged. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-viscosity material filling mechanism, which is used to solve the technical problems in the prior art, such as the large resistance when pushing the material due to the adhesion of the inner wall of the material filling nozzle and the intermolecular force when the material flows, which easily leads to uneven discharge of the material and thus a blocking phenomenon. In addition, since the valve body and the valve stem have large resistance during the advancement process and frequently block the valve stem, when the blocking phenomenon occurs, the valve stem is unevenly stressed and the internal stress surges, which leads to the technical problems that the valve stem and the valve body are easily damaged.

[0004] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a high-viscosity material pouring mechanism, comprising:

[0005] A filling cylinder connected to the material barrel;

[0006] A protective shell is fixedly mounted on the top of the filling cylinder, and a driving mechanism is arranged in the protective shell;

[0009] The elastic member is arranged in an array on the inner wall of the filling nozzle. The elastic member has a cavity inside and is connected to the air cavity. The piston reciprocates and adjusts the air pressure inside the cavity to deform the elastic member.

[0010] The elastic member includes an elastic arc plate in contact with the material. When the air pressure in the air cavity expands, the elastic arc plate convexly deforms toward the material. When the air pressure in the air cavity contracts, the elastic arc plate concavely deforms toward the air cavity, thereby achieving a bionic breathing dynamic response.

[0011] Preferably, the elastic member is arranged in an arc-shaped plate shape, and a splicing block and a splicing groove are provided on the side. A plurality of the elastic members are spliced together to achieve full coverage of the inner wall of the pouring nozzle.

[0012] Preferably, the elastic arc-shaped plates are deformed to convexly face the material, and V-shaped gaps are formed between the edges of adjacent elastic arc-shaped plates, so that the cross-section of the material channel becomes smaller.

[0013] Preferably, the elastic arc-shaped plate is deformed concavely toward the air cavity, and the cross-section of the material channel becomes larger.

[0014] Preferably, a rubber pad is provided in the inner cavity of the elastic member.

[0015] Preferably, a unit cavity communicating with the air cavity is opened in the middle of the rubber pad, the unit cavity and the elastic arc-shaped plate form a regular hexagonal honeycomb cavity, and a steel plate is fixedly provided on the inner wall of the unit cavity.

[0018] Preferably, a gear is rotatably provided inside the protective shell, and a transmission connection is formed between the edge of the gear and the piston.

[0019] Preferably, a rack is provided in the protective shell so as to move along the moving direction of the piston, and the rack is meshed with the gear.

[0020] In the above technical solution, the present invention provides a high-viscosity material pouring mechanism, which has the following beneficial effects:

[0021] The present invention provides an elastic member and an elastic arc plate, wherein the elastic member includes an elastic arc plate in contact with the material. When the air pressure in the air cavity expands, the elastic arc plate convexly deforms toward the material, and when the air pressure in the air cavity contracts, the elastic arc plate concavely deforms toward the air cavity, so as to achieve a bionic breathing-like dynamic response. Through the precise coordination of the positive and negative pressures, the elastic arc plate is repeatedly concave and convexly deformed, so that when the infusion is carried out, the infusion nozzle contacts the inner wall of the material to achieve a bionic breathing-like dynamic response. The positive and negative pressures are alternately driven to drive the micro-mechanical vibration, so as to peel off the adhesion layer on the wall of the infusion nozzle tube, reduce the adhesion force between the material and the wall of the infusion nozzle tube, thereby reducing the resistance when pushing the material, effectively avoiding the occurrence of the blocking phenomenon, making the material infusion smoother, thereby avoiding uneven force on the valve stem, resulting in a surge in internal stress, effectively protecting the valve stem and the valve body, and extending the service life of the valve stem and the valve body.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-11 As shown, a high viscosity material pouring mechanism includes:

[0038] Filling cylinder 1, which is connected to the material barrel;

[0039] A protective shell 2 is fixedly mounted on the top of the infusion cylinder 1, and a driving mechanism is arranged inside the protective shell 2;

[0040] A piston cylinder 9 is provided at the top of the infusion cylinder 1, and a piston 8 is provided in the piston cylinder 9 and is driven to move back and forth by a driving mechanism;

[0041] The pouring nozzle 3 is connected to the discharge port of the pouring barrel 1. An air cavity is opened in the wall of the pouring nozzle 3, and the air cavity is connected to the piston cylinder 9;

[0042] The elastic member 6 is arranged in an array on the inner wall of the filling nozzle 3. The interior of the elastic member 6 is arranged as a cavity and is connected to the air cavity. The piston 8 reciprocates and adjusts the air pressure inside the cavity to cause the elastic member 6 to deform.

[0043] 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 convexly deforms toward the material. When the air pressure in the air cavity contracts, the elastic arc plate 11 concavely deforms toward the air cavity, thereby achieving a bionic breathing dynamic response.

[0044] Specifically, the material barrel is connected to the filling cylinder 1 and the pressure cylinder through a three-way pipe. During filling, the first valve at the material barrel outlet and the second valve provided on the air inlet pipe of the pressure cylinder are opened, and the cylinder is started to drive the pressure block provided in the pressure cylinder to move toward the cylinder, so that the pressure cylinder is in a negative pressure state, and the material in the material barrel is drawn into the main pipe horizontally provided by the three-way pipe for temporary storage through the three-way pipe, and then the first valve is closed, and the third valve provided at the feed pipe of the filling cylinder 1 is opened, and the cylinder is started to drive the pressure block to move in the opposite direction, thereby pushing the material temporarily stored in the main pipe horizontally provided by the three-way pipe into the filling cylinder 1, thereby realizing quantitative material extraction.

[0045] Furthermore, during infusion, the hydraulic rod 4 fixedly mounted on the top of the protective shell 2 is started, thereby driving the valve stem 7 at the output end of the hydraulic rod 4 to move toward the infusion cylinder 1, thereby driving the valve body 10 fixedly connected to the end of the valve stem 7 to move synchronously, thereby pushing the material in the infusion cylinder 1 along the infusion nozzle 3 for infusion.

[0046] Furthermore, due to the high viscosity of the material, 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, due to the small diameter of the filling nozzle 3 pipe, when the high viscosity material passes through a narrow space, due to the adhesion of the inner wall of the material filling nozzle 3 and the force between molecules when the material flows, the resistance when pushing the material is large. When pushing, it is easy to cause the discharge to be not smooth, thereby causing the blocking phenomenon. Moreover, due to the large resistance between the valve body 10 and the valve stem 7 during the pushing process, the blocking phenomenon occurs frequently. When the blocking phenomenon occurs, the valve stem 7 is unevenly stressed, and the internal The stress surges, which makes the valve stem 7 and the valve body 10 susceptible to damage. Therefore, an air cavity connected to the piston cylinder 9 and an elastic member 6 arrayed on the inner wall of the filling nozzle 3 are opened in the tube 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 set on the top of the piston 8 to pass through the top of the piston cylinder 9 and reciprocate along the central axis 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 elastic member 6 undergoes the following deformation:

[0047] When the piston 8 moves from the top to the bottom of the piston cylinder 9 in the piston cylinder 9, the piston 8 adjusts the internal air pressure compression of the piston cylinder 9 and squeezes the gas in the piston cylinder 9 into the air cavity opened in the 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, so that the gas is introduced into the cavity of the elastic member 6 through the through hole connected to 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 continues to increase, thereby causing the elastic member 6 to inflate and deform. 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 continues to increase, the elastic arc plate 11 is deformed from being concave toward the cavity to being convex toward the material, thereby performing a slight radial squeezing on the material in the flow channel of the filling nozzle 3.

[0048] When the piston 8 moves from the bottom to the top of the piston cylinder 9 in the piston cylinder 9, the piston 8 adjusts the internal air pressure of the piston cylinder 9 to a negative pressure, and draws the air in the air cavity back into the piston cylinder 9 through the connecting pipe 5. As the gas in the air cavity is continuously drawn out, the air pressure in the air cavity gradually decreases to a negative pressure state, thereby allowing the gas in the cavity of the elastic member 6 to be drawn back into the air cavity through the through hole arranged between the elastic member 6 and the cavity. As the gas in the elastic member 6 is drawn out, the internal air pressure of the elastic member 6 continues to decrease, causing the elastic member 6 to shrink and deform due to air extraction. 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 shrinks and deforms, as the internal air pressure of the elastic member 6 continues to decrease, and under the action of the elastic arc plate 11's own recovery of deformation, the elastic arc plate 11 recovers its deformation from being convex in the direction of the material to being concave in the direction of the cavity.

[0049] Therefore, through the precise coordination of the above-mentioned positive and negative pressures, the elastic arc plate 11 is repeatedly concave and convex and deformed, so that during infusion, the infusion nozzle 3 contacts the inner wall of the material to achieve a bionic breathing dynamic response, and the positive and negative pressures are alternately driven to drive the micro-mechanical vibration, thereby peeling off the adhesion layer on the tube wall of the infusion nozzle 3, reducing the adhesion between the material and the tube wall of the infusion nozzle 3, thereby reducing the resistance when pushing the material, effectively avoiding the occurrence of the obstruction phenomenon, making the material infusion smoother, thereby avoiding uneven force on the valve stem 7, resulting in a surge 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.

[0050] Furthermore, a rubber layer is provided on the edge of the valve body 10 so that the valve body 10 can produce adaptive deformation when it moves with the elastic member 6. It should be noted that the above-mentioned driving mechanism can be an electric push rod driving the piston 8 to move back and forth along the central axis of the piston cylinder 9, or a motor driving the screw rod to drive the piston 8 to move back and forth along the central axis of the piston cylinder 9, or technical means known to those skilled in the art can be used to realize the reciprocating movement of the piston 8 along the central axis of the piston cylinder 9.

[0051] As a further embodiment of the present invention, the elastic member 6 is arranged in an arc-shaped plate shape, and a splicing block and a splicing groove are provided on the side. Multiple elastic members 6 are spliced together to achieve full coverage of the inner wall of the pouring nozzle 3.

[0052] Specifically, the elastic member 6 has two sides along the horizontal direction, one side of which is fixed 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 together, thereby surrounding the inner wall of the filling nozzle 3 at the corresponding position so that the elastic member 6 is spliced into a complete ring and covers the inner wall of the filling nozzle 3 in this area.

[0053] Furthermore, the elastic member 6 has two sides along the vertical direction, one side of which is fixed with a splicing block, and the other side is provided with a splicing groove, so that multiple groups of elastic members 6 spliced in a circular ring are spliced along the vertical direction of the inner wall of the filling nozzle 3, so that the elastic members 6 are spliced to cover the entire inner wall of the filling nozzle 3, thereby achieving full coverage of the inner wall of the filling nozzle 3, avoiding large gaps between adjacent elastic members 6, which causes the material to adhere to the gaps and cannot be discharged cleanly, affecting the accuracy of the discharge amount, thereby achieving full coverage of the filling nozzle 3 tube wall by alternating positive and negative pressure driving while ensuring the accuracy of the discharge amount, thereby achieving comprehensive and dead-angle-free stripping of the adhesion layer on the tube wall of the filling nozzle 3, reducing the adhesion force between the material and the tube wall of the filling nozzle 3, thereby reducing the resistance when pushing the material, effectively avoiding the occurrence of obstruction, making the material filling smoother, thereby avoiding uneven force on the valve stem 7, resulting in a surge 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.

[0054] As a further embodiment of the present invention, the elastic arc plates 11 are deformed to convexly face the material, and V-shaped gaps are formed between the edges of adjacent elastic arc plates 11, so that the cross section of the material channel becomes smaller.

[0055] Specifically, the elastic members 6 are spliced to achieve full coverage of the inner wall of the filling 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, when the elastic member 6 is inflated and deformed, as the internal air pressure of the elastic member 6 continues to increase, the elastic arc plate 11 is deformed from being concave toward the cavity to being convex toward the material, thereby performing a slight radial extrusion on the material in the flow channel of the filling nozzle 3, and forming a V-shaped gap at the joint between the two adjacent elastic arc plates 11. As the elastic arc plate 11 is deformed from being concave toward the cavity to being convex toward the material, the material in the V-shaped gap is squeezed toward the middle by the two sides of the V-shaped gap, and the angle between the V-shaped gaps gradually becomes smaller, so that the material in the V-shaped gap is squeezed toward the middle of the filling nozzle 3, further avoiding the material from being stuck in the V-shaped gap and affecting the discharge amount.

[0056] Furthermore, by splicing the elastic members 6 to achieve full coverage of the inner wall of the filling nozzle 3, as the elastic arc-shaped plate 11 deforms from being concave toward the cavity to being convex toward the material, the cross-sectional area of the material channel of the filling nozzle 3 becomes smaller. According to the principle that the flow velocity is low at a large cross-section and high at a small cross-section, the material in the filling nozzle 3 is squeezed to accelerate the flow, further making the material discharge smoother, further avoiding the occurrence of obstruction, and improving the accuracy and efficiency of the filling.

[0057] As a further embodiment provided by the present invention, the elastic arc-shaped plate 11 is deformed concavely toward the air cavity, and the cross-section of the material channel becomes larger.

[0058] 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 shrinks and deforms when air is evacuated. 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 shrinks and deforms, as the internal air pressure of the elastic member 6 continues to decrease, and under the action of the elastic arc plate 11's own deformation recovery, 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.

[0059] Furthermore, by fully covering the equivalent local turbulence, dead angles are achieved to prevent materials from adhering to the inner wall of the filling nozzle 3, further improving the filling effect and the smoothness of discharge. By the continuous protrusion and depression of the elastic arc plate 11, surrounding vibrations and local vortices are formed on the inner wall of the filling nozzle 3, and a shear layer is formed by generating a flow velocity difference through the sudden change of the flow channel cross-sectional area, which effectively eliminates bubbles in the discharge process and further improves the filling effect.

[0060] As a further embodiment of the present invention, a rubber pad is provided in the inner cavity of the elastic member 6 .

[0061] 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.

[0062] 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. A steel plate is fixed on the inner wall of the unit cavity.

[0063] 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 form a regular hexagonal honeycomb cavity. A steel plate is fixed 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 convex deformation or concave deformation, thereby realizing a bionic breathing 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.

[0064] 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 the side close to the material.

[0065] Specifically, a gap is provided between the elastic arc plate 11 and the surface of the rubber pad close to the material, thereby providing deformation space for the elastic arc plate 11 .

[0066] As a further embodiment provided by the present invention, elastic microspheres are provided in the unit cavity, and the diameter of the elastic microspheres is larger than the diameter of the air inlet of the unit cavity.

[0067] Specifically, elastic microspheres are arranged in the unit cavity. Since the unit cavity and the elastic arc plate 11 form a regular hexagonal honeycomb cavity, a steel plate is fixedly arranged on the inner wall of the unit cavity. As the honeycomb cavity is inflated or deflated, the elastic member 6 is inflated and deformed or deflated, so that the elastic arc plate 11 is convexly deformed or concavely deformed. As the gas continuously alternates in and out of the honeycomb cavity, the elastic microspheres continuously gain speed in the honeycomb cavity and move, and rebound irregularly in the honeycomb cavity. The vibration wave is transmitted to the flow channel through the honeycomb wall. The movement trajectory of the small ball covers the cavity surface. The shape of the honeycomb cavity is optimized through simulation, so that the collision of the small balls presents chaotic characteristics to achieve irregular rebound motion. Through the gradient depth of the hexagonal unit and the chaotic cavity design, the random collision energy is converted into directional mechanical waves to achieve directional energy concentration. The vibration mechanical wave is transmitted to the flow channel and the material through the honeycomb wall, further increasing the shear rate, effectively reducing the adhesion of the material and the viscosity between the material molecules, so that the material flow is smoother, further improving the infusion efficiency and infusion effect, and effectively reducing material residue.

[0068] As a further embodiment of the present invention, a gear is rotatably provided inside 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 move back and forth in the piston cylinder 9 to adjust the internal air pressure of the piston cylinder 9 .

[0069] As a further embodiment of the present invention, a rack is provided in the protective shell 2 along the moving direction of the piston 8, and the rack is meshed with the gear.

[0070] Specifically, the rack is fixedly connected to the valve stem 7. When the valve stem 7 moves, the rack moves synchronously with the valve stem 7, thereby driving the gear to rotate synchronously, and the hinged rod hinged between the edge of the gear and the piston rod of the piston 8 drives the piston rod to move back and forth, thereby driving the piston 8 to reciprocate in the piston cylinder 9, so that there is no need for an additional drive source to drive the piston 8 to move back and forth, thereby saving production costs and failure rate, and enabling the piston 8 to respond synchronously when extruding and discharging.

[0071] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various 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.
