Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, specifically to a fully automatic non-destructive quantitative filling device for pickled vegetables. Background Technology

[0002] In the pickled vegetable processing industry, especially for the automated filling of shredded or strip-shaped pickled vegetables, existing technologies generally face two major technical challenges.

[0003] Firstly, regarding the challenge of filling fibrous materials: Traditional measuring cup filling machines struggle with this type of material because pickled vegetables are often loose and disorganized, with strands easily protruding irregularly from the top of the measuring cup. As the measuring cup moves horizontally to the filling position, these protruding portions come into contact with other parts of the equipment, disrupting production continuity and leading to filling failures. Furthermore, even if filling is successful, the disordered shape of the pickled vegetables inside the container affects the product's appearance and makes subsequent sealing of packaging bags or boxes difficult.

[0004] Secondly, since pickled vegetable products are sold as a solid-liquid mixture, current filling methods typically involve weighing or measuring the solid and liquid components together before filling the container. This method results in the sauce filling the spaces between the pickled vegetables and overflowing before the vegetables themselves. This leads to a higher sauce content in the initial stages of filling, causing significant sauce overflow when the solid pickled vegetables enter the measuring cup. Furthermore, it can also lead to a higher proportion of pickled vegetables in the later stages of filling, resulting in inconsistent solid-liquid ratios within the same batch and severely impacting product quality stability.

[0005] Therefore, how to achieve precise, non-destructive quantitative filling of shredded or strip-shaped pickles and ensure a constant solid-liquid ratio is a technical bottleneck that urgently needs to be solved in the field of automated pickle production. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a fully automatic non-destructive quantitative filling device for pickled vegetables, which solves the problems of orderly filling of shredded or strip-shaped pickled vegetables and the different solid-liquid ratios after filling.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic non-destructive quantitative filling device for pickled vegetables, comprising a base and an infeed section and a discharge section disposed on the base. The infeed section is provided with a hopper, and a feeding nozzle is disposed below the hopper. The discharge section is provided with a pushing piston and a second propulsion cylinder that drives the pushing piston to move up and down. It also includes a feeding measuring cup, which can be driven by a first propulsion cylinder to reciprocate between the infeed section and the discharge section. A third propulsion cylinder is vertically disposed on one side of the hopper. A bracket is disposed at the output end of the third propulsion cylinder, and a motor is disposed on the bracket. A main shaft inserted into the hopper is disposed at the output end of the motor, and a claw penetrating the feeding nozzle is disposed at the bottom of the main shaft.

[0008] The bottom of the feed nozzle is connected to a material feeding cup located in the feeding section. The material feeding cup has openings at both the top and bottom ends corresponding to the feed nozzle and the feeding cup. The inner cavity of the material feeding cup is provided with a clamping cylinder, which is a multi-lobed plate with equal divisions. When the inserter is inserted into the clamping cylinder, a gap cavity is formed between the two. At least one of the plates is movably arranged. When the inserter rotates in the clamping cylinder, the movably arranged plate can move relative to the inserter to adjust the size of the gap cavity.

[0009] Preferably, the inner cavity of the feed cup is an elliptical cavity in the top view projection; the clamping cylinder includes a first half-clamping cylinder fixedly disposed on one side of the elliptical cavity and a second half-clamping cylinder movably disposed on the other side of the elliptical cavity opposite to the first half-clamping cylinder; a fourth propulsion cylinder for driving the displacement of the second half-clamping cylinder is provided on the outer side of the feed cup; wherein, when the second half-clamping cylinder is away from the first half-clamping cylinder, a material receiving cavity is formed between it and the insert claw; when the second half-clamping cylinder is close to the first half-clamping cylinder, they can be interlocked to form a complete circle.

[0010] Preferably, a back plate fixed to the material handling measuring cup is provided on the back side of the second half clamping cylinder. A plurality of comb teeth are provided on the front side of the back plate. The comb teeth penetrate the second half clamping cylinder, and the comb teeth are hidden in the second half clamping cylinder after the second half clamping cylinder is attached to the first half clamping cylinder.

[0011] Preferably, the inserter includes a disk connected to the main shaft, and a plurality of inserting teeth are arranged circumferentially opposite to each other on the lower part of the disk, with gap grooves formed between the oppositely arranged inserting teeth.

[0012] Preferably, a piston cylinder is arranged parallel to one side of the first push cylinder, and a piston is arranged in the inner cavity of the piston cylinder. One end of the piston is connected to the first push cylinder through a first pull rod, and the other end is connected to the feeding cup through a second pull rod.

[0013] The top of the piston cylinder front end is connected to the bottom of the hopper via a liquid guide pipe, and a liquid delivery pipe is connected to the bottom of the front end. A nozzle is provided at the end of the liquid delivery pipe, and the nozzle is located below the feeding section.

[0014] Preferably, a second check valve is provided at the connection between the liquid guide tube and the piston cylinder, and a first check valve is provided at the connection between the liquid delivery tube and the piston cylinder.

[0015] Preferably, the top of the feeding cup is fixed with a platform, and the platform has an opening and a closing part on both sides, wherein when the feeding cup moves to the unloading section, the closing part blocks the bottom of the feeding cup.

[0016] Preferably, the inner cavity of the hopper is provided with a mesh plate inclined from the inlet to the nozzle, the mesh plate dividing the inner cavity of the hopper into an upper cavity for placing solid materials and a lower cavity for placing sauce materials, and the liquid guide tube is connected to the lower cavity.

[0017] Preferably, a baffle plate is inclinedly arranged in the upper cavity, the bottom of the baffle plate is facing the mesh plate, and a material passage gap is formed between the baffle plate and the mesh plate.

[0018] Preferably, the inner wall of the hopper is provided with a retaining sleeve for stabilizing the main shaft, the retaining sleeve is penetrated by the main shaft, and a linear bearing that slides with the main shaft is provided inside the retaining sleeve.

[0019] The beneficial effects of this invention are as follows: By using the fully automatic non-destructive quantitative filling device for pickled vegetables provided by this invention, compared with the prior art, the device, through the cooperation of the claw and the clamping cylinder, can pre-wrap loose and messy filamentous or strip-shaped pickled vegetables into a regular cylindrical shape through rotation, extrusion, and combing operations. This solves the problem of inaccurate quantitative filling caused by the uncertain shape of the material, ensures that the pickled vegetables can enter the feeding cup completely and smoothly, avoids interference and jamming caused by the pickled vegetables protruding from the cup opening, and guarantees the stability and reliability of the equipment operation.

[0020] The piston cylinder synchronizes the processing, conveying, and sauce extraction of solid pickles. When the feeding cup moves to pick up material, it simultaneously extracts a fixed amount of sauce; when the feeding cup moves to fill, the system simultaneously pushes a fixed amount of sauce, ensuring a consistent solid-liquid ratio in each product and greatly improving the stability of product quality.

[0031] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation schemes as long as the effects of the present invention can be achieved.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] like Figure 8 As shown, the pickled vegetable filling machine proposed in the prior art specifically includes a base 1 and an infeed section and a discharge section located on the base 1. A hopper 3 is provided at the infeed section, and a nozzle 24 is provided below the hopper 3; a pusher piston 5 and a second pusher cylinder 4 that drives the pusher piston 5 to move up and down are provided at the discharge section; it also includes a feeding measuring cup 6, which can be driven by the first pusher cylinder 2 to move back and forth between the infeed section and the discharge section, so that after the feeding measuring cup 6 receives the pickled vegetables falling from the hopper 3 at the infeed section, it is pushed by the first pusher cylinder 2 to the discharge section. At this time, the second pusher cylinder 4 drives the pusher piston 5 to descend and push the pickled vegetables in the feeding measuring cup 6 into the container.

[0035] Based on the aforementioned prior art, this embodiment discloses a fully automatic non-destructive quantitative filling device for pickled vegetables. Its purpose is to provide a filling equipment capable of filling shredded or strip-shaped pickled vegetables. Specifically, as follows... Figures 1-7 As shown, a frame is provided on the top of one side of the hopper 3. A third propulsion cylinder 21 is vertically mounted on the frame. A bracket is provided at the output end of the third propulsion cylinder 21, and a motor 22 is mounted on the bracket. A main shaft inserted into the hopper 3 is provided at the output end of the motor 22, and a claw 25 penetrating the feed nozzle 24 is provided at the bottom of the main shaft. In implementation, the third propulsion cylinder 21 is used to drive the motor 22, the main shaft, and the claw 25 to rise and fall, and the motor 22 is used to drive the main shaft and the claw 25 to rotate.

[0036] Furthermore, to ensure the stability of the claw 25 during rotation, this embodiment provides a retaining sleeve 34 for stabilizing the main shaft on the inner wall of the hopper 3, such as... Figure 1 , Figure 2 and Figure 7 As shown, the retaining cylinder 34 is penetrated by the main shaft, and a linear bearing 35 that slides with the main shaft is installed inside. The retaining cylinder 34 limits the middle position of the main shaft, ensuring that the main shaft can rise and fall while also rotating stably.

[0037] Furthermore, in this embodiment, the inserter 25 is as follows: Figures 3-4 Or such as Figures 5-6 As shown, the inserter 25 includes a disc connected to the main shaft. The outer diameter of the disc is smaller than the inner diameter of the feed nozzle 24, so that the inserter 25 can move freely up and down within the feed nozzle 24. Several inserting teeth 32 are arranged circumferentially opposite each other on the lower part of the disc, and gap grooves 33 are formed between the oppositely arranged inserting teeth 32.

[0038] In addition, a feeding measuring cup 23 located in the feeding section is connected to the bottom of the nozzle 24. The feeding measuring cup 23 has openings at both its upper and lower ends corresponding to the nozzle 24 and the feeding measuring cup 6. The inner cavity of the feeding measuring cup 23 is provided with a clamping cylinder, which is composed of equally divided multi-lobed plates. At least one plate is movably disposed, and a gap cavity is formed between the inserter 25 and the clamping cylinder when the inserter 25 is inserted into the clamping cylinder. In an exemplary embodiment, when the inserter 25 descends, it carries shredded or strip-shaped pickled vegetables into the clamping cylinder within the feeding measuring cup 23. At this time, the disc of the inserter 25 and the clamping cylinder form a volumetric cavity for quantitatively measuring the pickled vegetables, and the pickled vegetables being filled at one time are pressed down into this space. When the motor 22 drives the inserter 25 to rotate inside the clamping cylinder, the rotating inserter 32 carries the filamentous or strip-shaped pickled vegetables in a rotary motion. At this time, the movable plate can move relative to the inserter 25 to adjust the size of the gap cavity. When the movable plate moves, it squeezes the pickled vegetables, causing the filamentous or strip-shaped pickled vegetables to rotate under the squeezed state. The filamentous or strip-shaped pickled vegetables located outside the inserter 25 are wrapped around the inserter 25 to form a regular cylindrical shape. At this time, the filamentous or strip-shaped pickled vegetables are constrained by the inserter 25 into a ring-shaped cylinder, which facilitates the filamentous or strip-shaped pickled vegetables to enter the feeding cup 6 during feeding. It also prevents the pickled vegetables, due to their filamentous or strip-shaped shape, from irregularly protruding from the top of the feeding cup 6, avoiding interference or jamming of other parts when the cup moves, which would affect the conveying of the feeding cup 6, and facilitating the subsequent sealing of the pickled vegetable packaging bags or boxes.

[0039] In this embodiment, as Figure 4 and Figure 6 As shown, the inner cavity of the feed cup 23 is an elliptical cavity in the top view projection; the clamping cylinder includes a first half clamping cylinder 26 fixedly disposed on one side of the elliptical cavity and a second half clamping cylinder 27 movably disposed on the other side of the elliptical cavity opposite to the first half clamping cylinder 26; a fourth propulsion cylinder 29 for driving the displacement of the second half clamping cylinder 27 is provided on the outside of the feed cup 23.

[0040] For example, such as Figure 3 and Figure 4 As shown, when the second half of the clamping cylinder 27 moves away from the first half of the clamping cylinder 26, a material receiving cavity 28 is formed between it and the insert claw 25, as follows. Figure 5 and Figure 6As shown, when the second half-clamping cylinder 27 is close to the first half-clamping cylinder 26, they can interlock to form a complete circle. Specifically, in the first usage state of the feeding cup 23, the second half-clamping cylinder 27 is away from the first half-clamping cylinder 26. At this time, a receiving cavity 28 is formed between the first half-clamping cylinder 26 and the inserter 25, increasing the internal receiving space of the feeding cup 23 so that it can accommodate more fluffy and messy shredded or strip-shaped pickles. As the inserter 25 rotates, the second half-clamping cylinder 27 is driven by the fourth pusher cylinder 29 to fit against the first half-clamping cylinder 26 to form a complete circle. The feeding cup 23 then changes to the second usage state, squeezing the receiving cavity 28 out of existence, so that the shredded or strip-shaped pickles are placed tightly and neatly inside the clamping cylinder.

[0041] Furthermore, to ensure the orderly winding of the shredded or strip-shaped pickled vegetables in the circumferential direction, a back plate 31, fixed to the measuring cup 23, is provided on the back of the second half-clamping cylinder 27. Several comb teeth 30 are provided on the front side of the back plate 31, penetrating the second half-clamping cylinder 27. After the second half-clamping cylinder 27 is fitted with the first half-clamping cylinder 26, the comb teeth 30 are hidden within the second half-clamping cylinder 27. With this design, when the rotating insert 32 carries the shredded or strip-shaped pickled vegetables in a rotary motion, the contact between the circumferential pickled vegetables and the comb teeth 30 is confined to the space between adjacent comb teeth 30, ensuring that the circumferential winding portion of the pickled vegetables is evenly distributed by the comb teeth 30, forming a more uniform and orderly shape within the clamping cylinder.

[0042] Based on the above embodiments, this embodiment also discloses a second embodiment, specifically: a piston cylinder 8 is arranged parallel to one side of the first propulsion cylinder 2, and a piston 9 is arranged inside the piston cylinder 8. One end of the piston 9 is connected to the first propulsion cylinder 2 through a first pull rod 7, and the other end is connected to the feeding cup 6 through a second pull rod 10. The top of the front end of the piston cylinder 8 is connected to the bottom of the hopper 3 through a liquid guide pipe 15, and a liquid delivery pipe 12 is connected to the bottom of the front end. A nozzle 13 is arranged at the end of the liquid delivery pipe 12, and the nozzle 13 is located below the feeding section.

[0043] In actual operation, piston 9 is initially positioned at the front end of piston cylinder 8. The first push cylinder 2 advances, driving piston 9, the second push rod 10, and the feeding cup 6 to move backward synchronously via the first pull rod 7. At this time, the feeding cup 6 is below the sorting cup 23, and piston 9 is behind piston cylinder 8. The displacement of piston 9 creates negative pressure at the front end of piston cylinder 8, drawing sauce from hopper 3 through the liquid guide pipe 15. After the solid pickled vegetables in sorting cup 23 fall into feeding cup 6, the first push cylinder 2 retracts, moving feeding cup 6 to the unloading section. The sauce in piston cylinder 8 is pushed by piston 9, guided by the liquid delivery pipe 12, and sprayed out through nozzle 13 to the unloading section, allowing the solid pickled vegetables and sauce to be filled together in the filling container. This configuration allows for the separate filling of solid pickled vegetables and sauce, achieving quantitative separation and one-time filling of solids and sauce.

[0044] Furthermore, a second one-way valve 14 is provided at the connection between the liquid guide pipe 15 and the piston cylinder 8 to prevent the sauce from flowing back into the hopper 3 through the liquid guide pipe 15 during the piston 9 pushing phase. A first one-way valve 11 is provided at the connection between the liquid delivery pipe 12 and the piston cylinder 8 to prevent the piston 9 from drawing in excess gas through the liquid delivery pipe 12 during the pull-back phase.

[0045] Furthermore, a platform 16 is fixed to the top of the feeding measuring cup 6. An opening and a closing part are respectively provided on both sides of the platform 16. When the feeding measuring cup 6 moves to the unloading section, the closing part blocks the bottom of the material handling measuring cup 23.

[0046] In this embodiment, the hopper 3 is as follows: Figure 1 and Figure 2 As shown, a mesh plate 17 is inclinedly installed in the inner cavity of the hopper 3 from the inlet to the spout 24. The mesh plate 17 divides the inner cavity of the hopper 3 into an upper cavity 18 for placing solid materials and a lower cavity 19 for placing sauce materials. After the materials are poured into the hopper 3, the solid pickles are blocked in the upper cavity 18 by the mesh plate 17, while the sauce passes through the mesh plate 17 into the lower cavity 19, thus separating the solid pickles and the sauce. It should be noted that the liquid guide pipe 15 is connected to the lower cavity 19.

[0047] An inclined baffle plate 20 is provided in the upper cavity 18, with the bottom of the baffle plate 20 facing the mesh plate 17, and a material passage gap is formed between the baffle plate 20 and the mesh plate 17. When the pickled vegetables are poured in, the solid pickled vegetables are blocked between the baffle plate 20 and the mesh plate 17. As the pickled vegetables are continuously filled, this part of the pickled vegetables slides down the mesh plate 17 towards the nozzle 24 along the material passage gap.

[0048] The working principle of the device is as follows: when the pickled vegetables are poured into the hopper 3, the solid filamentous / strip-shaped pickled vegetables are blocked in the upper cavity 18 when the material passes through the inclined mesh plate 17, while the sauce flows through the mesh plate 17 into the lower cavity 19, thus achieving solid-liquid separation. At this time, the pickled vegetables in the upper cavity 18 are guided by the baffle plate 20 and slide along the mesh plate 17 towards the feed nozzle 24.

[0049] The third propulsion cylinder 21 drives the inserter 25 to descend and insert into the pile of pickled vegetables in the hopper 3, carrying the fluffy pickled vegetables through the feed nozzle 24 into the sorting cup 23. At this time, the sorting cup 23 is in its first use state. The motor 22 starts, driving the inserter 25 to rotate inside the clamping cylinder. The rotating inserter teeth 32 drive the filamentous or strip-shaped pickled vegetables to rotate. While the inserter 25 is rotating, the fourth propulsion cylinder 29 drives the second half of the clamping cylinder 27 to move towards the first half of the clamping cylinder 26, causing the containing cavity 28 to gradually shrink. During this process, the second half of the clamping cylinder 27 squeezes the pickled vegetables, and at the same time, the comb teeth 30 extending from its back side comb the pickled vegetables circumferentially, making them evenly distributed. When the second half of the clamping cylinder 27 and the first half of the clamping cylinder 26 are engaged, the messy pickled vegetables are squeezed and wrapped around the inserter 25, forming a regular cylindrical column of pickled vegetables.

[0050] The first propulsion cylinder 2 is activated, which, via the first pull rod 7 and the second pull rod 10, moves the feeding measuring cup 6 horizontally to directly below the sorting measuring cup 23. Simultaneously, the piston 9, linked to it, moves from the rear end to the front end within the piston cylinder 8, creating a negative pressure at the front end of the piston cylinder 8. This negative pressure draws a measured amount of sauce from the lower cavity 19 of the hopper 3 into the front end of the piston cylinder 8 through the liquid guide pipe 15. Once the feeding measuring cup 6 is in place, the insert claw 25 descends again, pushing the formed pickled vegetable column into the feeding measuring cup 6.

[0051] The first propulsion cylinder 2 retracts, moving the feeding cup 6 containing the pickled vegetable column to the discharging section. Simultaneously, the piston 9 is pushed back by the liquid in the piston cylinder 8, spraying the sauce at the front end of the piston cylinder 8 through the liquid delivery pipe 12 from the nozzle 13 into the container. At the same time, the second propulsion cylinder 4 drives the pushing piston 5 to descend, pushing the pickled vegetable column in the feeding cup 6 into the container.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
