Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a food filling device. Background Technology

[0002] In the food processing industry, food is usually packaged into packaging materials. Take mustard greens as an example. Mustard greens are a common pickled vegetable. When pickled mustard greens are sold in the market, each head of pickled mustard greens needs to be cut open and packaged in a fixed quantity according to specifications. After the cut mustard greens are put into the packaging bag, they need to be squeezed into a ball and not scattered at the back of the packaging bag. The core of the mustard greens must be displayed in the transparent part of the packaging bag.

[0003] Chinese patent document CN112193518A discloses a sauerkraut bottle filling device. In this device, a conveyor belt moves the sauerkraut bottles as a whole. After the sauerkraut is fed in through the top opening of the hopper, a stirring motor drives a stirring paddle to break up any clumps of sauerkraut. Simultaneously, a positioning claw, driven by the extension and retraction of a telescopic rod, positions the sauerkraut bottles directly below the discharge port. The stirred sauerkraut is then filled through the discharge port. The applicant has discovered some defects in this technical solution:

[0004] 1) After the material is discharged from the hopper, the pickled cabbage needs to be manually added back into the hopper and broken up before the filling can continue. The filling is not continuous, the production efficiency is low, and the degree of automation is low.

[0005] 2) Multiple portions of sauerkraut are added to the hopper at one time, broken up, and then filled one portion at a time by controlling the valve. This cannot guarantee that each portion of sauerkraut contains the heart of the cabbage, resulting in poor filling uniformity. Furthermore, it is also impossible to precisely control the weight of each portion of sauerkraut, resulting in low filling accuracy. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a food filling device with simple and compact structure, high filling continuity, good filling uniformity, high filling accuracy and high production efficiency.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A food filling device includes a feeding conveyor, a filling conveyor, and a recycling conveyor. The feeding conveyor, filling conveyor, and recycling conveyor form a circulating conveyor line to circulate and transport material barrels. The filling conveyor is provided with a plurality of spaced filling ports and filling port baffles for opening and closing the filling ports. A material feeding mechanism is provided above the filling port and a filling hopper assembly is provided below it.

[0009] As a further improvement to the above technical solution:

[0010] The filling and conveying mechanism includes a filling circulation line and a conveying guide trough located on the outer periphery of the filling circulation line. The filling circulation line is provided with a plurality of spaced-apart paddles. The filling port is opened on the conveying guide trough. The inlet of the conveying guide trough is connected to the outlet of the feeding conveying mechanism, and the outlet of the conveying guide trough is connected to the inlet of the recycling conveying mechanism.

[0011] The conveying guide groove is U-shaped.

[0012] The feeding conveying mechanism includes a feeding conveyor line, the outlet of which is higher than the inlet, the outlet of which is connected to the inlet of the conveying guide trough, and the inlet of which is connected to the outlet of the recycling conveying mechanism.

[0013] The feeding conveyor line is equipped with multiple baffles arranged at intervals.

[0014] The recycling conveying mechanism includes a recycling guide trough, the inlet of which is connected to the outlet of the conveying guide trough, and the outlet of the recycling guide trough is connected to the inlet of the feeding conveyor line.

[0015] The recycling guide trough is equipped with an interval pushing component, which includes a pushing drive and a dial wheel. The pushing drive drives the dial wheel to rotate to periodically push the material bucket.

[0016] The filling hopper assembly includes a fixed filling hopper connected below the filling port and a lifting filling hopper that is lifted and lowered on the fixed filling hopper.

[0017] The material-poke mechanism includes a material-poke drive component, a material-poke rod, and a timing belt assembly. The material-poke drive component is connected to the material-poke rod via the timing belt assembly to drive the material-poke rod to rise and fall.

[0018] The filling port, filling hopper assembly, and shovel rod are arranged in a concentric structure.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This invention relates to a food filling device. A feeding conveyor, a filling conveyor, and a recycling conveyor form a circulating conveyor line to circulate the material barrels, separating the feeding and filling stations. The feeding mechanism can continuously fill, resulting in high filling continuity, high production efficiency, and a high degree of automation. Furthermore, the material barrels can be repeatedly recycled, reducing redundancy in the device. The structure is simple and compact. During feeding, the sauerkraut can be pre-cut, weighed, and kneaded. The feeding conveyor can then feed the sauerkraut portion by portion, ensuring good filling uniformity and high filling accuracy. By setting a filling port baffle, the baffle covers the filling port when the first material barrel passes the first and second filling ports, preventing the sauerkraut from falling into the filling port. This allows for multiple filling ports to be set up simultaneously, resulting in a reasonable structure and high production efficiency.

[0021] The food filling device of this utility model has a feeding conveyor mechanism that transports the material barrels to the conveying guide trough. The filling circulation line drives the moving plates to move, and each material barrel is sequentially inserted into each moving plate. The moving plates transport the material barrels evenly and orderly, so that each material barrel is aligned with each filling port. This prevents the material barrels from being too scattered or piled up during the conveying process, simplifies the positioning process of the material barrels and filling ports, and has high reliability and high production efficiency.

[0022] The food filling device of this utility model has a U-shaped conveying guide trough with parallel inlet and outlet, which allows the feeding conveying mechanism and the recycling conveying mechanism to be arranged in parallel, resulting in a compact structure and reasonable layout.

[0023] The food filling device of this utility model has an outlet height that is higher than the inlet height of the feeding conveyor line, that is, the height of the filling conveyor mechanism is also higher than the inlet height of the feeding conveyor line. This provides operating space for the packaging, conveying and sealing processes of the packaging bags after filling, and the layout is more reasonable.

[0024] The food filling device of this utility model has higher reliability by setting baffles to prevent the material barrel from sliding down or tilting backward and tipping over during the lifting process.

[0025] This invention relates to a food filling device. During filling, the packaging bag is placed below the filling hopper assembly, and the lifting filling hopper descends and extends into the packaging bag before filling. This prevents vegetable leaves from remaining at the opening of the packaging bag, which could cause the seal to be loose, resulting in air leakage or juice leakage.

[0026] The food filling device of this utility model has a concentric arrangement of the filling port, the filling hopper assembly and the feeding rod, so that the feeding rod, the filling port and the filling hopper assembly are aligned during each filling. Accurate filling can be achieved simply by positioning the outer packaging bag with the filling hopper assembly. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figures 1 to 7 As shown, the food filling device of this embodiment includes a feeding conveying mechanism 1, a filling conveying mechanism 2 and a recycling conveying mechanism 3. The feeding conveying mechanism 1, the filling conveying mechanism 2 and the recycling conveying mechanism 3 form a circulating conveying line to circulate the material barrel 9. The filling conveying mechanism 2 is provided with a plurality of spaced filling ports 21 and filling port baffles 22 for opening and closing the filling ports 21. A material feeding mechanism 4 is provided above the filling port 21 and a filling hopper assembly 5 is provided below it.

[0040] In this embodiment, sauerkraut is used as an example to illustrate the filling process. In this embodiment, the food filling device, during filling, adds the sauerkraut, processed through cutting, weighing, and kneading, to the material buckets 9. Each material bucket 9 contains one portion of sauerkraut to be filled. The feeding conveying mechanism 1 transports the material buckets 9 to the filling conveying mechanism 2 to complete the feeding. The filling conveying mechanism 2 transports the three material buckets 9 to the three filling ports 21, opens the filling port baffle 22, and the sauerkraut falls from the bottom of the material buckets 9 into the filling hopper assembly 5. The material-pushing mechanism 4 pushes the material, filling the sauerkraut in the filling hopper assembly 5 into the packaging bag (not shown in the figure) below the filling hopper assembly 5. The filling conveying mechanism 2 continues to transport the material buckets 9 to the recycling conveying mechanism 3 to complete the filling. The recycling conveying mechanism 3 collects the empty material buckets 9, adds new sauerkraut to the collected perforated material buckets 9, and the recycling conveying mechanism 3 continues to transport the material buckets 9 to the feeding conveying mechanism 1 for a new round of feeding, filling, and recycling. In this embodiment, the food filling device comprises a feeding conveyor 1, a filling conveyor 2, and a recycling conveyor 3, forming a circulating conveyor line to circulate the material barrel 9. This separates the feeding and filling stations, allowing the material feeding mechanism 4 to continuously fill the material, resulting in high filling continuity, high production efficiency, and a high degree of automation. Furthermore, the material barrel 9 can be repeatedly recycled, reducing redundancy in the device and creating a simple and compact structure. During feeding, the sauerkraut can be pre-cut, weighed, and kneaded. The feeding conveyor 1 can feed the sauerkraut portion by portion, resulting in good filling uniformity and high filling accuracy. By setting a filling port baffle 22, when the first material barrel 9 passes the first and second filling ports 21, the baffle 22 covers the filling port 21, preventing the sauerkraut in the material barrel 9 from falling out of the filling port 21. This allows for the simultaneous filling of multiple filling ports 21, resulting in a reasonable structure and high production efficiency.

[0041] In this embodiment, the bottom of the material bucket 9 has an opening, and the material bucket 9 forms a receiving space with the conveying surfaces of the feeding conveying mechanism 1, the filling conveying mechanism 2, and the recycling conveying mechanism 3, so that the sauerkraut will not leak out of the material bucket 9 during conveying. Of course, in other embodiments, the bottom of the material bucket 9 can also be provided with an openable and closable bottom baffle. When the material bucket 9 is conveyed to the filling port 21, the bottom baffle can be opened to allow the material to fall. Preferably, in this embodiment, the filling port baffle 22 is connected to a cylinder (not shown in the figure) for opening and closing, which is simple and reliable in structure.

[0042] Furthermore, such as Figure 4 As shown, in this embodiment, the filling and conveying mechanism 2 includes a filling circulation line 23 and a conveying guide trough 24 located on the outer periphery of the filling circulation line 23. The filling circulation line 23 is provided with multiple spaced-apart paddles 221. A filling port 21 is opened on the conveying guide trough 24. The inlet of the conveying guide trough 24 is connected to the outlet of the feeding conveying mechanism 1, and the outlet of the conveying guide trough 24 is connected to the inlet of the recycling conveying mechanism 3. After the feeding conveying mechanism 1 conveys the material bucket 9 into the conveying guide trough 24, the filling circulation line 23 drives the paddles 221 to move. Each material bucket 9 is sequentially inserted into each paddle 221, and the paddles 221 convey the material bucket 9 evenly and orderly, aligning each material bucket 9 with each filling port 21. This prevents the material buckets 9 from being too dispersed or piled up during the conveying process, simplifies the positioning process between the material buckets 9 and the filling ports 21, and ensures high reliability and high production efficiency.

[0043] Furthermore, such as Figure 4 As shown, in this embodiment, the conveying guide trough 24 is U-shaped. The inlet and outlet of the U-shaped conveying guide trough 24 are parallel, which allows the feeding conveying mechanism 1 and the recycling conveying mechanism 3 to be arranged in parallel, resulting in a compact structure and reasonable layout.

[0044] In this embodiment, the filling circulation line 23 is a synchronous belt pulley structure. The two straight sections of the U-shaped conveying guide trough 24 correspond to the two sides of the synchronous belt, and the arc section of the U-shaped conveying guide trough 24 corresponds to a synchronous pulley. The filling port 21 is opened on a straight section of the conveying guide trough 24, making the structure more compact.

[0045] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the feeding conveying mechanism 1 includes a feeding conveyor line 11. The height of the outlet of the feeding conveyor line 11 is higher than the height of the inlet. The outlet of the feeding conveyor line 11 is connected to the inlet of the conveying guide trough 24, and the inlet of the feeding conveyor line 11 is connected to the outlet of the recycling conveying mechanism 3. The height of the outlet of the feeding conveyor line 11 is higher than the height of the inlet, meaning the height of the filling conveying mechanism 2 is also higher than the height of the inlet of the feeding conveyor line 11. This provides operating space for the packaging, conveying, and sealing processes of the filled bags, resulting in a more rational layout. Preferably, in this embodiment, the feeding conveyor line 11 is a lifting chain conveyor belt.

[0046] Furthermore, such as Figure 3 As shown in this embodiment, the feeding conveyor line 11 is provided with multiple baffles 12 arranged at intervals. Since the material bucket 9 needs to be lifted upwards when it is conveyed on the feeding conveyor line 11, the baffles 12 are provided to prevent the material bucket 9 from sliding down or tilting backwards and tipping over during the lifting process, thus improving reliability.

[0047] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the recycling conveying mechanism 3 includes a recycling guide trough 31. The inlet of the recycling guide trough 31 is connected to the outlet of the conveying guide trough 24, and the outlet of the recycling guide trough 31 is connected to the inlet of the feeding conveyor line 11. Since the outlet height of the feeding conveyor line 11 is higher than the inlet height, the feeding conveyor line 11 lifts the material bucket 9, making the inlet height of the recycling guide trough 31 higher than the outlet height. The material bucket 9 entering the recycling guide trough 31 can fall and be recycled under the action of gravity. The structure is simple and reasonable.

[0048] In this embodiment, both the conveying guide trough 24 and the recycling guide trough 31 are guide trough structures, and baffles are provided on both sides of the feeding conveyor line 11, which can limit the displacement of the material barrel 9 in the non-working direction during the conveying process, making the conveying more stable.

[0049] Furthermore, such as Figure 7 As shown, in this embodiment, the recycling guide trough 31 is provided with an interval pushing component 32. The interval pushing component 32 includes a pushing drive component 321 and a dial wheel 324. The pushing drive component 321 drives the dial wheel 324 to rotate, thereby periodically pushing the material buckets 9. Specifically, the interval pushing component 32 also includes a connecting rod 322 and a rotating shaft 323. The pushing drive component 321 is disposed on the recycling guide trough 31. One end of the connecting rod 322 is hinged to the pushing drive component 321, and the other end is connected to the rotating shaft 323. The dial wheel 324 is mounted on the rotating shaft 323. The material buckets 9 falling from the recycling guide trough 31 are blocked by the dial wheel 324. The pushing drive component 321 drives the dial wheel 324 to rotate back and forth. The reciprocatingly rotating dial wheel 324 periodically pushes the material buckets 9 downward, preventing the material buckets 9 from accumulating during the falling recycling process, thus ensuring an orderly recycling process.

[0050] Furthermore, such as Figure 5 As shown, in this embodiment, the filling hopper assembly 5 includes a fixed filling hopper 51 connected below the filling port 21 and a lifting filling hopper 52 that is lifted and lowered on the fixed filling hopper 51. During filling, the packaging bag is placed below the filling hopper assembly 5, and the lifting filling hopper 52 descends and extends into the packaging bag before filling. This prevents vegetable leaves from remaining at the opening of the packaging bag, which could cause the seal to be loose, resulting in air leakage or juice leakage.

[0051] Furthermore, such as Figure 6As shown, in this embodiment, the material-pumping mechanism 4 includes a material-pumping drive component 43, a material-pumping rod 45, and a synchronous belt assembly. The material-pumping drive component 43 is connected to the material-pumping rod 45 via the synchronous belt assembly to drive the material-pumping rod 45 to rise and fall. Driving the material-pumping rod 45 to rise and fall via the synchronous assembly results in a simple structure and stable transmission. Specifically, the synchronous belt assembly includes a drive pulley 41, a driven pulley 42, and a synchronous belt 44 wound between the drive pulley 41 and the driven pulley 42. The material-pumping drive component 43 is connected to the drive pulley 41, and the material-pumping rod 45 is connected to one side of the synchronous belt 44 for rising and falling. In this embodiment, the material-pumping mechanism 4 also includes a guide sleeve 46, in which the material-pumping rod 45 slides. The guide sleeve 46 guides the material-pumping rod 45, preventing it from deviating during the material-pumping process, resulting in good material-pumping and filling effects.

[0052] Furthermore, such as Figure 2 As shown, in this embodiment, the filling port 21, the filling hopper assembly 5, and the material-push rod 45 are arranged concentrically. This concentric arrangement ensures that during each filling operation, the material-push rod 45, the filling port 21, and the filling hopper assembly 5 are aligned. Accurate filling can be achieved simply by positioning the outer packaging bag with the filling hopper assembly 5.

Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model using the methods and techniques disclosed above, or modify it into equivalent embodiments with equivalent changes, without departing from the spirit and technical solution of the present utility model.
