Description

Technical Field

[0001] The invention relates to the technical field of yogurt filling, in particular to a sweet embryo yogurt filling device and a filling method thereof that prevents blockage. Background Art

[0002] Tianbizi yogurt is a special drink that combines yogurt and sweet dough. Its appearance is attractive, and the white and delicate yogurt forms a sharp contrast with the brown of the sweet dough. In terms of taste, the mellow and smooth yogurt and the chewy texture of the sweet dough complement each other. The sweet dough exudes a unique wheat aroma, and the grains are full and elastic, bringing rich layers and changes to the taste buds. In addition, Tianbizi yogurt is not only delicious, but also rich in protein, calcium and dietary fiber, which is a double enjoyment of nutrition and deliciousness. In summer, it is a good product for cooling off and quenching thirst, and is deeply loved by consumers.

[0003] After the production of sweet yogurt, it will be poured into a temporary storage barrel before filling. There are multiple pipes connected to the bottom of the barrel. The pipes can guide the finished yogurt into the filler through a pump or other power equipment, and the filler will pour the yogurt into the yogurt packaging shell. However, the filler itself is not always in use. When a single batch of yogurt is filled, the next batch of yogurt will enter the filler for a short wait, and then be poured into the yogurt packaging shell. Since the yogurt will be stored in a storage barrel before filling, although the external settings of the storage barrel However, after shutdown, due to the complexity of cleaning the inside of the filler, the small part of yogurt remaining in the filler will gradually solidify, especially when the sweet dough is missed during homogenization. The solidified yogurt will repeatedly wrap the missed sweet dough. When the machine is started next time, the solidified yogurt will block the filler and cause the subsequent yogurt that has not solidified to be washed into the yogurt packaging shell together with the solidified yogurt, which will reduce the quality of the finished yogurt with the sweet dough and cause consumers' doubts.

[0014] Preferably, a slide groove is provided on the inner side of the protection frame, a directional rail is fixedly installed on the outer surface of the stamping shell, and the inner surface of the protection frame located in the slide groove is slidably connected to the outer surface of the directional rail.

[0015] A method for preventing clogging of sweet embryo yogurt filling:

[0016] S1: The yogurt is introduced into the liquid storage shell through the liquid inlet pipe until the liquid storage shell, the stamping shell and the interior of the isolation shell are all filled with yogurt, and the cylinder pushes the yogurt in the isolation shell downward through the push rod, so that the yogurt in the isolation shell quickly enters the space between the isolation shell and the stamping shell, and enters the space between the rubber piston and the closing cover;

[0017] S2: The cylinder then pulls the rubber piston back again, causing negative pressure to appear under the rubber piston, thereby forcing the filling plug to move upward to block the passage of the yogurt into the negative pressure space under the rubber piston. Since the rubber piston can squeeze the yogurt when moving upward, the yogurt flows downward through the liquid flow channel;

[0018] S3: When the rubber piston moves to the initial state, the yogurt in the liquid storage shell will be quickly filled due to the negative pressure in the isolation shell, pushing the filling plug back to its original position.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present application, the yogurt is filled into the liquid storage shell through the cooperation among the stamping shell, the liquid storage shell, the isolation shell, the push rod, the rubber piston, the closing cover, the electromagnet, the limit ring and the filling plug. When the cylinder pulls up the rubber piston upwards through the push rod, the yogurt is filled into the isolation shell. Then the cylinder can push the rubber piston downwards, and the rubber piston can slide downwards into the isolation shell, thereby pushing the yogurt in the isolation shell into the space between the stamping shell and the isolation shell. As the rubber piston moves downwards, a negative pressure space is formed in the space between the rubber piston and the closing cover, which can suck the yogurt between the stamping shell and the liquid storage shell into the gap between the rubber piston and the closing cover. When the cylinder drives the push rod to move upwards, it can drive the rubber piston to squeeze the yogurt between the rubber piston and the closing cover, so that the yogurt returns to its original path. The electromagnet is turned on, which can attract the closing cover so that the closing cover can be tightly attached to the outer surface of the stamping shell. Therefore, the pressure generated when the rubber piston moves upwards is not enough to push the closing cover, so that the rubber piston and the closing cover can be smoothly connected. The yogurt between the rubber piston and the sealing cover is squeezed into the space between the isolation shell and the stamping shell. When the rubber piston moves downward and then upward, due to the poor fluidity of the yogurt, a negative pressure space will be formed under the rubber piston. Before most of the yogurt has time to flow back into the isolation shell, the filling plug will move upward due to the negative pressure until it contacts the bottom surface of the limiting ring. At this time, due to the blocking of the limiting ring and the filling plug, the space between the rubber piston and the filling plug always maintains a negative pressure state. Subsequently, the yogurt between the rubber piston and the closing cover enters the position between the isolation shell and the stamping shell due to the upward lifting of the rubber piston. Because the isolation shell leaves a smaller channel for the yogurt to pass through, it is equivalent to homogenizing the yogurt again. This time, the homogenization can break up the solidified yogurt in the stamping shell and mix it into the liquid yogurt. At this time, due to the adsorption of negative pressure, the liquid flow channel of the filling plug can be aligned with the channel reserved for the yogurt in the isolation shell. Therefore, the yogurt after the second homogenization can be filled downward through the liquid flow channel, thereby solving the problem that the solidified yogurt will block the filler.

[0021] 2. The cooperation between the stamping shell, the threaded channel and the isolation shell of the present application is that the threaded channel can separate the stamping shell and the isolation shell into channels above and below the threads. Such channels can extend the flow distance of the yogurt in the isolation shell and the stamping shell, but the pressure and suction on the yogurt remain unchanged. Therefore, the homogenization quality of the yogurt during flow can be improved, so that the yogurt can be integrated with the broken yogurt solids, thereby reducing the probability of obvious solids appearing in the yogurt.

[0022] 3. The isolation shell, the square narrow channel and the circular narrow channel of the present application cooperate with each other. When the yogurt in the isolation shell is subjected to pressure, the yogurt will be forced to flow into the square narrow channel due to the pressure. Thanks to the principle that liquid cannot be compressed, when the pressure increases in a short period of time, the yogurt will also increase the flow rate. The flowing yogurt can wash away all or most of the yogurt solidified on the surface of the isolation shell or the stamping shell. Thanks to the high flow rate and high pressure, the solidified yogurt is broken up by the square narrow channel and the circular narrow channel and merged with the flowing yogurt, which also improves the quality of homogenization before filling.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution of a sweet embryo yogurt filling device and a filling method thereof for preventing blockage, comprising a stamping shell 1, a liquid storage shell 2 is fixedly installed on the upper surface of the stamping shell 1, an isolation shell 3 is arranged inside the stamping shell 1, and the top and bottom ends of the isolation shell 3 are respectively fixedly installed with the inner top surface and the inner bottom surface of the stamping shell 1, a cylinder 4 is arranged above the stamping shell 1, an inlet push rod 22 is fixedly installed at the output end of the cylinder 4, a rubber piston 5 is fixedly installed at the bottom end of the inlet push rod 22, and a closing cover 6 is slidably connected to the outer surface of the inlet push rod 22. When the cylinder 4 pulls up the rubber piston 5 through the inlet push rod 22, the yogurt will be filled. Entering the isolation shell 3, the cylinder 4 can then push the rubber piston 5 downward, and the rubber piston 5 can slide downward into the isolation shell 3, thereby pushing the yogurt in the isolation shell 3 into the space between the stamping shell 1 and the isolation shell 3. As the rubber piston 5 moves downward, a negative pressure space is formed in the space between the rubber piston 5 and the closing cover 6, which can suck the yogurt between the stamping shell 1 and the isolation shell 3 into the space between the rubber piston 5 and the closing cover 6. When the cylinder 4 drives the push rod 22 to move upward, it can drive the rubber piston 5 to squeeze the yogurt between the rubber piston 5 and the closing cover 6, so that the yogurt returns to its original path.

[0035] An electromagnet 7 is installed inside the rubber piston 5. The outer surface of the rubber piston 5 is slidably connected to the inner wall of the isolation shell 3. When the electromagnet 7 is turned on, it can tightly absorb the closing cover 6. When the rubber piston 5 enters the isolation shell 3, the electromagnet 7 is turned on, and at this time it can attract the closing cover 6, so that the closing cover 6 can be tightly attached to the outer surface of the stamping shell 1. Therefore, the pressure generated when the rubber piston 5 moves upward is not enough to push the closing cover 6, so that the yogurt between the rubber piston 5 and the closing cover 6 can be smoothly squeezed into the space between the isolation shell 3 and the stamping shell 1. The rubber piston 5 is made of rubber sponge. Sponge rubber is a kind of rubber with a porous structure, which has excellent elasticity and flexibility. It can be compressed and restore its original shape after the pressure stabilizes. The surface of the rubber piston 5 is provided with a plurality of annular grooves, which can reduce the contact area between the rubber piston 5 and the isolation shell 3. Thanks to the strong elasticity of the rubber piston 5 itself, when the rubber piston 5 moves downward and is subjected to high pressure, the yogurt can squeeze the rubber piston 5, causing the rubber piston 5 to be deformed at the position of the annular groove and produce a gap, and a small amount of yogurt can flow upward through the gap into the liquid storage shell 2 until the yogurt below returns to normal pressure.

[0036] A sealing ring 8 is fixedly installed on the bottom surface of the closing cover 6, and the outer surface of the sealing ring 8 is in close contact with the inner wall of the isolation shell 3 and the outer surface of the stamping shell 1. The sealing ring 8 itself is made of EPDM rubber and has excellent high-pressure resistance. It can reduce the wear of the closing cover 6 on the surface of the stamping shell 1 and increase the airtightness between the stamping shell 1 and the closing cover 6.

[0037] A limit ring 9 is fixedly installed on the inner wall of the isolation shell 3, and a filling plug 10 is slidably connected to the inner wall of the stamping shell 1 below the limit ring 9. A number of liquid flow channels 11 are provided on the inner side of the filling plug 10. When the rubber piston 5 moves downward and then upward, a negative pressure space is formed below the rubber piston 5 due to the poor fluidity of the yogurt. Before most of the yogurt has time to flow back into the isolation shell 3, the filling plug 10 will move upward due to the negative pressure until it contacts the bottom surface of the limit ring 9. At this time, due to the blocking of the limit ring 9 and the filling plug 10, the space between the rubber piston 5 and the filling plug 10 always maintains a negative pressure state, and then the rubber piston 5 and the sealing cover The yogurt between 6 is pushed upward by the rubber piston 5 and enters the position between the isolation shell 3 and the stamping shell 1. When the yogurt passes through the circular narrow channel 15 and the square narrow channel 14, the circular narrow channel 15 and the square narrow channel 14 reduce the flow space, which is equivalent to homogenizing the yogurt again. This time the homogenization can break up the solidified yogurt in the stamping shell 1 and mix it into the liquid yogurt. At this time, due to the adsorption of negative pressure, the liquid flow channel 11 of the filling plug 10 can be aligned with the channel reserved for the yogurt in the isolation shell 3. Therefore, the yogurt after the second homogenization can be filled downward through the liquid flow channel 11, thereby solving the problem that the solidified yogurt will block the filler.

[0038] The inner wall of the stamping shell 1 is fixedly installed with a threaded channel 12, and the outer surface of the threaded channel 12 is fixedly installed with the outer surface of the isolation shell 3. When the yogurt enters the interior of the stamping shell 1 and the space between the stamping shell 1 and the isolation shell 3, the threaded channel 12 can separate the stamping shell 1 and the isolation shell 3 into a threaded channel above and below. This channel can extend the flow distance of the yogurt in the isolation shell 3 and the stamping shell 1, but the pressure and suction on the yogurt remain unchanged. Therefore, the homogenization quality of the yogurt during flow can be improved, so that the yogurt can be integrated with the broken yogurt solid, thereby reducing the probability of obvious solids appearing in the yogurt.

[0039] The isolation shell 3 is located on the inner side near the filling plug 10 and is provided with several square narrow channels 14. The isolation shell 3 is located on the inner side near the liquid storage shell 2 and is provided with several circular narrow channels 15. When the yogurt in the isolation shell 3 is subjected to pressure, the yogurt will be forced to flow into the square narrow channels 14 due to the pressure. Benefiting from the principle that liquid cannot be compressed, when the pressure increases in a short time, the yogurt will also increase the flow rate. The flowing yogurt can wash away all or most of the yogurt solidified on the surface of the isolation shell 3 or the stamping shell 1. Benefiting from the high flow rate and high pressure, the solidified yogurt is broken up by the square narrow channels 14 and the circular narrow channels 15 and merged with the flowing yogurt, and the quality of homogenization before filling is also improved.

[0040] A closed cover 16 is fixedly installed on the outer surface of the liquid storage shell 2 by bolts, a liquid inlet pipe 17 is provided on the inner side of the closed cover 16, the inner wall of the closed cover 16 is slidably connected to the outer surface of the push rod 22, a one-way valve is provided inside the liquid inlet pipe 17 to ensure that the liquid inlet pipe 17 maintains a one-way flow, the closed cover 6 and the liquid storage shell 2 can form a sealed space to ensure that there is no air inside the equipment, so as to reduce the shelf life of the yogurt after production to a level not much different from the expected shelf life.

[0041] A mounting frame 18 is fixedly installed on the outer surface of the cylinder 4, and a mounting frame 2 19 is fixedly installed on the outer surface of the liquid storage shell 2. The mounting frame 18 and the mounting frame 2 19 are both fixed to the external support surface by bolts. The mounting frame 18 and the mounting frame 2 19 are installed with the external supporting equipment so that the distance between the cylinder 4 and the liquid storage shell 2 will not change.

[0042] An extension tube 20 is fixedly installed at the bottom end of the filling plug 10, and a protective frame 21 is fixedly installed on the outer surface of the extension tube 20. The inner wall of the protective frame 21 is slidably connected to the outer surface of the stamping shell 1. When the filling plug 10 is moved up and down due to suction from above or its own gravity, it can synchronously drive the protective frame 21 to move together, so as to reduce the occurrence of misalignment and tilt of the filling plug 10 when moving, thereby preventing external air from entering the equipment.

[0043] A slide groove is provided on the inner side of the protection frame 21, and a directional rail 13 is fixedly installed on the outer surface of the stamping shell 1. The inner surface of the protection frame 21 located in the slide groove is slidably connected to the outer surface of the directional rail 13. The protection frame 21 can move up and down in the direction given by the directional rail 13 through the slide groove. The inner surface of the slide groove is inlaid with balls. When the directional rail 13 moves up and down, the balls themselves will also rotate, which can ensure that the filling plug 10 will not be misplaced when moving up and down, while reducing the friction between the protection frame 21 and the stamping shell 1, so that the protection frame 21 is more flexible when moving up and down.

[0044] The yogurt is introduced into the liquid storage shell 2 through the liquid inlet pipe 17 until the liquid storage shell 2, the stamping shell 1 and the interior of the isolation shell 3 are all filled with yogurt. The cylinder 4 pushes the yogurt in the isolation shell 3 downward through the push rod 22, so that the yogurt in the isolation shell 3 quickly enters the space between the isolation shell 3 and the stamping shell 1, and enters the space between the rubber piston 5 and the closing cover 6. There are two liquid inlet pipes 17, one of which can input yogurt into the liquid storage shell 2, and the other liquid inlet pipe 17 can be interconnected with the container for storing yogurt at the upper level, so that the liquid in the liquid storage shell 2 can flow to each other, reduce the coagulation phenomenon and reduce the air in the liquid storage shell 2.

[0045] Then the cylinder 4 pulls back the rubber piston 5 again, so that negative pressure is present under the rubber piston 5, thereby forcing the filling plug 10 to move upward to block the passage of the yogurt into the negative pressure space under the rubber piston 5. Since the rubber piston 5 can squeeze the yogurt when moving upward, the yogurt flows downward through the liquid flow channel 11. Since the electromagnet 7 is installed inside the rubber piston 5, the electromagnet 7 can attract the closing cover 6, forcing the closing cover 6 and the rubber piston 5 to squeeze the yogurt against each other, so that the yogurt can flow quickly between the isolation shell 3 and the stamping shell 1. The principle that liquid cannot be compressed is utilized, and because the yogurt has poor fluidity, the yogurt is forced to be homogenized again to break up or disperse the solidified solid yogurt, and at the same time, the negative pressure generated under the rubber piston 5 is utilized to pull up the filling plug 10, so that the yogurt can be filled downward through the liquid flow channel 11 inside the filling plug 10.

[0046] When the rubber piston 5 moves to the initial state, the yogurt in the liquid storage shell 2 will be quickly filled due to the negative pressure in the isolation shell 3, pushing the filling plug 10 back to its original position. When the rubber piston 5 moves upward and is about to leave the isolation shell 3, the negative pressure between the rubber piston 5 and the filling plug 10 is the largest. After the rubber piston 5 leaves the isolation shell 3, the strong negative pressure will cause the yogurt in the liquid storage shell 2 to be quickly filled into the isolation shell 3, and the strong impact brought by the yogurt can press the filling plug 10 back to its original position.

[0047] During normal use, yogurt can be filled into the equipment, so that the stamping shell 1, the liquid storage shell 2 and the isolation shell 3 are all filled with yogurt. When filling is required, the cylinder 4 drives the push rod 22 to push the rubber piston 5 downward. During this period, the electromagnet 7 inside the rubber piston 5 is started at a low power, so that the closing cover 6 can move downward together with the rubber piston 5. Since the downward movement of the rubber piston 5 is bound to squeeze the yogurt in the liquid storage shell 2, according to the principle that liquid cannot be compressed, a small amount of yogurt located in the liquid storage shell 2 will flow back from another liquid inlet pipe 17 to the upper-level container for storing yogurt, so that the yogurt pressure in the liquid storage shell 2 remains stable. When the rubber piston 5 is pressed down to the isolation shell 3 but has not yet reached the circular narrow channel 15, When the rubber piston 5 is in the isolation shell 3, the yogurt below it, including the inside of the isolation shell 3 and between the stamping shell 1 and the isolation shell 3, can generate high pressure due to extrusion. The yogurt close to the rubber piston 5 will squeeze the rubber piston 5. The rubber piston itself is subject to its own excellent elasticity and compressibility, so that a small part of the yogurt can squeeze the edge of the rubber piston 5 to deform the rubber piston 5, thereby causing a gap between the rubber piston 5 and the isolation shell 3, and then a small part of the yogurt flows back into the liquid storage shell 2 through the gap until the rubber piston 5 reaches the bottom of the circular narrow channel 15. When the yogurt pressure below tends to be stable, the rubber piston 5 will rebound to its original shape and fit completely with the inner wall of the isolation shell 3 again. When the rubber piston 5 reaches the position located at the circular narrow channel At the same time, the power of the electromagnet 7 inside it increases, so that the closing cover 6 can drive the sealing ring 8 to isolate the yogurt inside the stamping shell 1 from the yogurt in the liquid storage shell 2. As the rubber piston 5 continues to push downward, the yogurt below the rubber piston 5 and in the isolation shell 3 is pressurized and quickly enters the space between the isolation shell 3 and the stamping shell 1 from the square narrow channel 14. During this period, the space between the rubber piston 5 and the closing cover 6 becomes larger and larger, generating a strong negative pressure, so that the yogurt between the isolation shell 3 and the stamping shell 1 enters the rubber piston 5 and the closing shell through the circular narrow channel 15. When the rubber piston 5 moves downward to the bottom, the electromagnet 7 inside the rubber piston 5 turns on the maximum function, and then the piston pushes back. , cooperating with the magnetic attraction force, drives the rubber piston 5 to move upward quickly, thereby pushing the yogurt above to return along the original path, but the yogurt liquid is relatively viscous, so the upward movement of the rubber piston 5 will cause a strong negative pressure vacuum state to be generated below. Before the yogurt has time to enter under the rubber piston 5, the filling plug 10 will move upward due to the attraction of the negative pressure and cling to the bottom surface of the limiting ring 9, so that the liquid flow channel 11 can be aligned with the square narrow channel 14, so that the yogurt can be normally filled downward through the liquid flow channel 11. Subsequently, when the rubber piston 5 is able to upwardly detach from the isolation shell 3, a large vacuum is generated in the isolation shell 3, so that the yogurt in the liquid storage shell 2 can be refilled into the isolation shell 3.

The anti-clogging sweet embryo yogurt filling device according to claim 4, characterized in that: A slide groove is provided on the inner side of the protection frame (21), a directional rail (13) is fixedly mounted on the outer surface of the stamping shell (1), and the inner surface of the protection frame (21) located in the slide groove is slidably connected to the outer surface of the directional rail (13).

6. A method for preventing clogging of sweet embryo yogurt filling, characterized in that The filling device according to any one of claims 1 to 5 is used, comprising the following steps: S1: Yogurt is introduced into the liquid storage shell (2) through the liquid inlet pipe (17) until the liquid storage shell (2), the punching shell (1) and the interior of the isolation shell (3) are all filled with yogurt, and the cylinder (4) pushes the yogurt in the isolation shell (3) downwards through the push rod (22), so that the yogurt in the isolation shell (3) quickly enters the space between the isolation shell (3) and the punching shell (1), and enters the space between the rubber piston (5) and the closing cover (6); S2: The cylinder (4) then pulls back the rubber piston (5) again, causing negative pressure to appear below the rubber piston (5), thereby forcing the filling plug (10) to move upward to block the passage of the yogurt into the negative pressure space below the rubber piston (5). Since the rubber piston (5) can squeeze the yogurt when moving upward, the yogurt flows downward through the liquid flow channel (11); S3: When the rubber piston (5) moves to the initial state, the yogurt in the liquid storage shell (2) is quickly filled due to the negative pressure in the isolation shell (3), pushing the filling plug (10) back to its original position.
