Description
Technical Field
[0001] The present invention relates to the field of paste filling, and particularly to a high-hardness filling process. Background Art
[0002] In industries such as chemical engineering, food, and medicine, it is often necessary to perform paste filling operations. However, due to their special physical properties, such as poor fluidity and high viscosity, high-hardness pastes pose great challenges to filling;
[0003] When traditional filling processes and equipment handle high-hardness pastes, the following situations occur. High-hardness pastes are difficult to flow smoothly like ordinary liquids or low-viscosity pastes, resulting in a large deviation between the actual filling volume and the preset volume during metering and filling, affecting product quality and cost control; In order to enable high-hardness pastes to enter the filling container, a large amount of time and relatively high pressure are often required, making the filling speed slow and unable to meet the needs of large-scale production. Summary of the Invention
[0004] The main purpose of the present invention is to provide a high-hardness filling process. The synergistic effect of the inclined-angle fan-shaped blades and the spiral propeller blades realizes the efficient homogenization and directional flow of the paste, improving both the filling accuracy and ensuring the continuity and stability of the conveying process.
[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:
[0006] A high-hardness filling process includes a base. A vertical frame is fixedly connected to the top of the base, and a top plate is fixedly connected to the top of the vertical frame. A multi-stage stirring structure is arranged at the bottom of the top plate. The multi-stage stirring structure includes two inclined-angle fan-shaped blades and a spiral propeller blade. A fixed cylinder is arranged at the bottom of the top plate. Two connecting rings are fixedly connected to the outer surface of the fixed cylinder, and the connecting rings are fixedly connected to the side surface of the vertical frame. A main shaft is rotatably connected to the inside of the fixed cylinder. The two inclined-angle fan-shaped blades are equidistantly located inside the fixed cylinder and fixedly connected to the outer surface of the main shaft. A feed pipe is fixedly connected to the top of the fixed cylinder, and a discharge slot is opened at the bottom of the fixed cylinder.
[0007] As a further solution of the present invention, a motor is fixedly connected to the top of the top plate, and the output shaft of the motor penetrates the bottom of the top plate and is fixedly connected to the top of the main shaft.
[0008] As a further solution of the present invention, the upper half of the fixed cylinder is cylindrical, the lower half of the fixed cylinder is conical, and the spiral propeller blade is also conical.
[0009] As a further solution of the present invention, a pulse-driven delivery pump is fixedly connected to the top of the base. The receiving end of the pulse-driven delivery pump is connected to the bottom of the fixed cylinder. A pipe valve is fixedly connected to the output end of the pulse-driven delivery pump and located at the top of the base. One end of the pipe valve is fixedly connected to a filling cylinder. A connecting pipe is fixedly connected to the bottom of the outer surface of the filling cylinder in a communicating manner. The bottom of the connecting pipe is fixedly connected to a filling head.
[0010] As a further solution of the present invention, a buffer structure is fixedly connected inside the connecting pipe. The buffer structure includes a conical shunt block and three buffer plates. The conical shunt block is fixedly connected inside the connecting pipe. Three support blocks are fixedly connected to the inner wall of the connecting pipe at equal intervals inside the conical shunt block. Both sides of the buffer plate are fixedly connected with rotating shafts. The buffer plate is rotatably connected to the support block through the rotating shafts.
[0011] As a further solution of the present invention, the buffer plate is triangular. The conical shunt block is composed of three triangular prisms. The top of the support block is provided with an inclined surface. The side surface of the buffer plate is arc-shaped. The buffer plate fits the side surface of the conical shunt block.
[0012] As a further solution of the present invention, three connecting seats are fixedly connected to the outer surface of the connecting pipe at equal intervals. A fixed box is fixedly connected to the side surface of the connecting seat. A disc spring is arranged inside the fixed box. One end of the disc spring is connected to the inner wall of the fixed box. One end of the rotating shaft penetrates through the inside of the fixed box and is fixedly connected to the other end of the disc spring.
[0013] The above embodiments of the present invention can achieve the following beneficial effects: The beveled fan-shaped blade applies a transverse shear force to the paste through its inclination angle and rotational movement, squeezes the material from top to bottom, effectively breaks up lumps and removes the air mixed in the stirring process, ensuring uniform dispersion of the paste. The spiral propeller blade uses the spiral structure to generate a continuous downward propelling force in the vertical direction, stably conveys the paste from the top of the fixed cylinder to the discharge chute at the bottom, overcomes the flow resistance of the high-hardness paste, and prevents material retention or blockage. The synergistic effect of the two realizes the high-efficiency homogenization and directional flow of the paste, improves the filling accuracy, and ensures the continuity and stability of the conveying process;
[0014] When the spiral propeller blade rotates, its pitch and diameter gradually change, forming a gradually compressed space from wide to narrow. The paste is forced to be squeezed in the spiral channel, and the internal air gathers towards the low-pressure area due to volume compression and finally is discharged through the discharge chute. At the same time, after the air is removed, the density of the paste tends to be uniform, avoiding the filling volume fluctuation caused by bubble residue. The residual air may form cavitation during high-pressure conveying, accelerating the wear of the pipeline and the filling head. After the air is discharged, the material flow is more stable, reducing the risk of cavitation;
[0015] The pulse-driven transfer pump pushes the paste through intermittent high pressure. The high-hardness paste will cause a violent impact on the filling head during the transfer process. Through the rotational design of the rotating shaft, the buffer plate converts the paste impact force into the kinetic energy of the buffer plate rotating downward, avoiding the direct action of high pressure on the internal structure of the filling head. The conical shunt block divides the paste into three independent flow channels. Combining with the synchronous action of the three buffer plates, it forces the paste to flow downward along a symmetrical path, eliminating the uneven local pressure caused by single-point concentrated filling and ensuring that the flow rate of each portion of the paste is consistent.
[0016] When the buffer plate rotates downward, it drives the rotating shaft to rotate counterclockwise, which in turn drives the disc spring to contract. Through the contraction of the disc spring, the buffering of the paste filling is further enhanced. And when the equipment is no longer in use, the buffer plate is no longer stressed, and the disc spring rebounds, driving the buffer plate to reset. Brief Description of the Drawings

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0026] As Figure 1 - Figure 7 shown, a high-hardness filling process includes a base 1. A vertical frame 2 is fixedly connected to the top of the base 1. A top plate 3 is fixedly connected to the top of the vertical frame 2. A multi-stage stirring structure 7 is arranged at the bottom of the top plate 3. The multi-stage stirring structure 7 includes two bevel-sector blades 8 and a screw-propelling blade 9. A fixed cylinder 5 is arranged at the bottom of the top plate 3. Two connecting rings 4 are fixedly connected to the outer surface of the fixed cylinder 5. The connecting rings 4 are fixedly connected to the side surface of the vertical frame 2. A main shaft 11 is rotatably connected to the inside of the fixed cylinder 5. The two bevel-sector blades 8 are equidistantly located inside the fixed cylinder 5 and are fixedly connected to the outer surface of the main shaft 11. A feed pipe 6 is fixedly connected to the top of the fixed cylinder 5. A discharge chute 12 is opened at the bottom of the fixed cylinder 5.
[0027] In specific implementation, the high-hardness paste to be filled is put into the inside of the fixed cylinder 5 through the feed pipe 6. Then, the motor 10 is started to drive the main shaft 11 to rotate synchronously, and further drive the two bevel-sector blades 8 and the screw-propelling blade 9 to rotate synchronously. The bevel-sector blade 8 applies a transverse shear force to the paste through its inclination angle and rotational movement, extruding the material from top to bottom, effectively breaking up lumps and removing the air mixed in the stirring process, ensuring the uniform dispersion of the paste. The screw-propelling blade 9 uses the spiral structure to generate a continuous downward propelling force in the vertical direction, stably transporting the paste from the top of the fixed cylinder 5 to the discharge chute 12 at the bottom, overcoming the flow resistance of the high-hardness paste and preventing material retention or blockage. The synergistic effect of the two realizes the high-efficiency homogenization and directional flow of the paste, improving the filling accuracy and ensuring the continuity and stability of the transportation process.
[0028] In this embodiment, a motor 10 is fixedly connected to the top of the top plate 3. The output shaft of the motor 10 penetrates the bottom of the top plate 3 and is fixedly connected to the top of the main shaft 11.
[0029] In this embodiment, the upper half of the fixed cylinder 5 is cylindrical, the lower half of the fixed cylinder 5 is conical, and the screw-propelling blade 9 is also conical.
[0030] When the screw-propelling blade 9 rotates, its pitch and diameter gradually change, forming a gradually compressed space from wide to narrow. The paste is forced to be extruded in the spiral channel, and the internal air gathers towards the low-pressure area due to volume compression and is finally discharged through the discharge chute 12. At the same time, after the air is discharged, the density of the paste tends to be uniform, avoiding the filling volume fluctuation caused by bubble residue. The residual air may form cavitation during high-pressure transportation, accelerating the wear of the pipeline and the filling head 17. After discharging the air, the material flow is more stable, reducing the cavitation risk.
[0031] In this embodiment, a pulse-driven transfer pump 13 is fixedly connected to the top of the base 1. The receiving end of the pulse-driven transfer pump 13 is connected to the bottom of the fixed cylinder 5. The output end of the pulse-driven transfer pump 13 and located at the top of the base 1 is fixedly connected with a pipe valve 14. One end of the pipe valve 14 is fixedly connected with a filling cylinder 15. The outer surface of the filling cylinder 15 near the bottom is communicated and fixedly connected with a connecting pipe 16. The bottom of the connecting pipe 16 is fixedly connected with a filling head 17.
[0032] In this embodiment, a buffer structure 18 is fixedly connected inside the connecting pipe 16. The buffer structure 18 includes a conical flow splitter 19 and three buffer plates 21. The conical flow splitter 19 is fixedly connected inside the connecting pipe 16. Three support blocks 20 are equidistantly fixedly connected to the inner wall of the connecting pipe 16 and inside the conical flow splitter 19. Both sides of the buffer plate 21 are fixedly connected with rotating shafts 24. The buffer plate 21 is rotationally connected to the support block 20 through the rotating shaft 24.
[0033] The paste after stirring and conveying is discharged through the discharge chute 12, and then conveyed by the pulse-driven transfer pump 13. At this time, the pipe valve 14 is opened, and the paste enters the inside of the filling cylinder 15, and then passes through the connecting pipe 16 and through the filling head 17 to complete the filling operation of the paste;
[0034] When the paste enters the inside of the connecting pipe 16, it will pass through the conical flow splitter 19, and then the paste will be split into three parts. These three parts of the paste will respectively squeeze the three buffer plates 21, and then the three buffer plates 21 will rotate downward. Then the three parts of the paste can move downward, and then complete the filling work through the filling head 17. The pulse-driven transfer pump 13 pushes the paste by intermittent high pressure. The high-hardness paste will generate a strong impact on the filling head 17 during the conveying process. The rotational design of the buffer plate 21 through the rotating shaft 24 converts the paste impact force into the kinetic energy of the buffer plate 21 rotating downward, avoiding the high pressure directly acting on the internal structure of the filling head 17. The conical flow splitter 19 divides the paste into three independent flow channels. Combining with the synchronous action of the three buffer plates 21, it forces the paste to flow downward along a symmetrical path, eliminating the local pressure unevenness caused by single-point concentrated filling, and ensuring that the flow rate of each part of the paste is consistent.
[0035] In this embodiment, the buffer plate 21 is triangular, the conical flow splitter 19 is composed of three triangular prisms, the top of the support block 20 is arranged in an inclined plane, the side surface of the buffer plate 21 is arc-shaped, and the buffer plate 21 fits the side surface of the conical flow splitter 19.
[0036] In this embodiment, three connecting seats 22 are fixedly connected to the outer surface of the connecting pipe 16 at equal intervals. A fixing box 23 is fixedly connected to the side surface of the connecting seat 22. A disc spring 25 is arranged inside the fixing box 23. One end of the disc spring 25 is connected to the inner wall of the fixing box 23, and one end of the rotating shaft 24 penetrates through the inside of the fixing box 23 and is fixedly connected to the other end of the disc spring 25.
[0037] When the buffer plate 21 rotates downward, it drives the rotating shaft 24 to rotate counterclockwise, thereby driving the disc spring 25 to contract. Through the contraction of the disc spring 25, the buffering of the paste filling is further improved. And when the device is no longer in use, the buffer plate 21 is no longer stressed, and the disc spring 25 rebounds, driving the buffer plate 21 to reset.
[0038] It should be noted that the present invention is a high-hardness filling process. When in use, the high-hardness paste to be filled is put into the inside of the fixed cylinder 5 through the feed pipe 6, and then the motor 10 is started to drive the main shaft 11 to rotate synchronously, thereby driving the two bevel sector blades 8 and the screw propeller blade 9 to rotate synchronously. The bevel sector blade 8 applies a transverse shear force to the paste through its inclination angle and rotational movement, extruding the material from top to bottom, effectively breaking up lumps and removing the air mixed in during the stirring process, ensuring the uniform dispersion of the paste. The screw propeller blade 9 uses the screw structure to generate a continuous downward propelling force in the vertical direction, stably transporting the paste from the top of the fixed cylinder 5 to the discharge chute 12 at the bottom, overcoming the flow resistance of the high-hardness paste, preventing material retention or blockage. The synergistic effect of the two realizes the high-efficiency homogenization and directional flow of the paste, not only improving the filling accuracy, but also ensuring the continuity and stability of the conveying process;
[0039] When the screw propeller blade 9 rotates, its pitch and diameter gradually change, forming a gradually compressed space from wide to narrow. The paste is forced to be extruded in the screw channel, and the internal air gathers towards the low-pressure area due to volume compression and finally is discharged through the discharge chute 12. At the same time, after the air is discharged, the density of the paste tends to be uniform, avoiding the filling volume fluctuation caused by bubble residue. Residual air may form cavitation during high-pressure conveying, accelerating the wear of the pipeline and the filling head 17. After the air is discharged, the material flow is more stable, reducing the risk of cavitation;
[0040] The paste that has completed stirring and conveying is discharged through the discharge chute 12, and then is conveyed by the pulse-driven delivery pump 13. At this time, the pipe valve 14 is opened, and the paste enters the inside of the filling cylinder 15, and the filling operation of the paste can be completed by passing through the connecting pipe 16 and the filling head 17;
[0041] When the paste enters the inside of the connecting pipe 16, it will pass through the conical shunt block 19, and then the paste will be divided into three parts. These three parts of the paste will respectively squeeze the three buffer plates 21, and then the three buffer plates 21 will rotate downward. Thus, the three parts of the paste can move downward, and then the filling work is completed through the filling head 17. The pulse-driven delivery pump 13 pushes the paste through intermittent high pressure. The high-hardness paste will generate a strong impact on the filling head 17 during the conveying process. Through the rotational design of the buffer plate 21 around the rotating shaft 24, the impact force of the paste is converted into the kinetic energy of the downward rotation of the buffer plate 21, avoiding the direct action of high pressure on the internal structure of the filling head 17. The conical shunt block 19 divides the paste into three independent flow channels. Combined with the synchronous action of the three buffer plates 21, the paste is forced to flow downward in a symmetrical path, eliminating the local pressure unevenness caused by single-point concentrated filling and ensuring that the flow rate of each portion of the paste is consistent.
[0042] When the buffer plate 21 rotates downward, it drives the rotating shaft 24 to rotate counterclockwise, thereby driving the disc spring 25 to contract. Through the contraction of the disc spring 25, the buffering of the paste filling is further enhanced. And when the equipment is no longer in use, the buffer plate 21 is no longer stressed, and the disc spring 25 rebounds, driving the buffer plate 21 to reset.
