Description

TECHNICAL FIELD

[0001] The present application relates to the field of food conveying, in particular to a food packaging device containing soup. BACKGROUND

[0002] In the food processing and packaging industry, solid-liquid mixed instant food is favored by consumers due to its rich taste and convenience, such as sour radish old duck soup, shiitake mushroom chicken soup, and braised pork. The packaging process of this type of food has strict requirements on the accuracy of the quantity, which directly affects the consistency of product quality and market reputation. If a solid-liquid mixed synchronous conveying packaging method is used, due to factors such as irregular shape of solid materials, density difference, and fluid entrapment, it is easy to have a large deviation in the amount of solid food in each bag of finished product. Some bags may only contain soup and very little solid, while others may have too much solid accumulation. This not only fails to meet the standardization requirements of food production, but also reduces the eating experience of consumers. Therefore, the industry generally uses a process scheme in which solid food and liquid soup are separately quantified and conveyed. The accurate quantification of solid food is completed first, and then the corresponding proportion of liquid soup is injected to ensure the uniformity of the amount of solid food in each bag of finished product. To meet the needs of solid food quantification and conveying, reciprocating quantitative bowl quantification and conveying systems are widely used in existing technologies. The core principle of this system is that a drive mechanism drives the quantitative bowl to move reciprocally between a feeding station and a discharging station. The solid food conveyed from the upstream is received at the feeding station and quantified. Then, the quantitative bowl moves to the discharging station, and the solid food inside the quantitative bowl is poured into the packaging bag through the overturning action of the quantitative bowl, achieving the quantitative distribution of solid food. However, the existing reciprocating quantitative bowl quantification and conveying scheme gradually exposes many technical defects in actual application, which seriously restricts production efficiency and quantification accuracy. The specific problems are as follows: The replacement operation of the quantitative bowl is complex and time-consuming: different specifications of solid-liquid mixed food have different quantitative requirements for solid food, and the corresponding volume of the quantitative bowl needs to be replaced to adapt to production. The existing quantitative bowl adopts fixing methods such as bolt fastening and buckle nesting. When replacing, special tools are needed to disassemble the original parts, and the new quantitative bowl needs to be positioned and calibrated. The entire process requires downtime, and the professional proficiency of the operator is required. Not only does it greatly prolong the downtime of the equipment, reduce the overall production efficiency of the production line, but also increase the labor cost of operation, which is difficult to meet the flexible production needs of the food processing industry in multiple batches and small batches. Solid food material is easy to adhere to the wall and cause uneven quantification: solid food materials (such as cooked pickled radish slices / strips, mushroom blocks, kelp segments, etc.) have a certain moisture content and viscosity. In the process of receiving material in the quantification bowl and turning off the material, it is easy to adhere to the wall of the quantification bowl due to molecular adsorption force, surface tension and other effects, especially on the bottom wall and the downward side wall during turning. Food material residues are more common. These adhered residues cannot be easily poured into the packaging bag along with the quantification bowl, on the one hand, the actual amount of solid food material in the single discharge is less than the calibrated volume of the quantification bowl, causing insufficient solid content in some bags; on the other hand, the residual food material will move to the next station with the quantification bowl in the subsequent circulation process, and will be discharged with the newly received food material, resulting in excessive solid content in some bags, ultimately causing fluctuations in the solid content of the entire line product, destroying the consistency of product quality, and even causing product scrap due to quantification deviation exceeding industry standards. SUMMARY

[0003] The present application aims to provide a food packaging equipment containing soup to solve the problems of uneven solid food content and complex operation of the quantification bowl in the existing food packaging method.

[0004] To achieve the above-mentioned purpose, the application adopts the following technical scheme: a food packaging equipment containing soup, comprising a soup filling device and a solid material filling device, the solid material filling device comprising a conveying mechanism, a filling cylinder and a material carrying mechanism driven on the conveying mechanism, the conveying mechanism comprising a conveying frame and a transmission chain circulatingly driven along the conveying frame, the material carrying mechanism comprising a material carrying container and a material carrying plate hinged at one end of the transmission chain, the material carrying plate being provided with a bottom cleaning unit and a clamping unit for clamping the material carrying container, the bottom cleaning unit being used for cleaning food attached to the bottom of the material carrying container, and the filling cylinder being arranged at the lower side of one end of the conveying mechanism for receiving the material in the material carrying container. Preferably, as an improvement, the clamping unit comprises two arc-shaped clamping plates, one end of the two arc-shaped clamping plates being rotatably connected to the material carrying plate, and the other end of the two arc-shaped clamping plates being close to each other under the action of elastic tension.

[0005] Preferably, as an improvement, the material carrying plate is provided with arc-shaped adjusting holes corresponding to each arc-shaped clamping plate, the arc-shaped adjusting holes being coaxially arranged with the rotation points of the arc-shaped clamping plates, and the arc-shaped clamping plates being provided with sliding columns sliding in the arc-shaped adjusting holes.

[0006] Preferably, as an improvement, one side of the material carrying plate away from the arc-shaped clamping plates is provided with a roller, and the conveying frame is provided with a conveying guide rail for the movement of the roller.

[0007] Preferably, as an improvement, the bottom cleaning unit comprises support plates arranged outside the clamping unit, the top of one support plate is hinged with a cover plate, and the free end of the cover plate is lapped on the other support plate.

[0008] Preferably, as an improvement, the height of the support plate overlapping with the free end of the cover plate is less than the height of the material loading container.

[0009] Preferably, as an improvement, a bottom cleaning assembly is arranged on the cover plate for extending into the interior of the material loading container, the bottom cleaning assembly comprising a support rod arranged on the cover plate and a scraper plate fixed on the support rod, the scraper plate being arranged obliquely and one side of the scraper plate being in contact with the inner bottom surface of the material loading container when the cover plate is in the closed state.

[0010] Preferably, as an improvement, the lower part of the material loading container is provided with an annular groove for cooperating with the arc-shaped clamping plates, and the inner cavity of the material loading container is in a square structure, and the high side of the scraper plate is in contact with the side wall of the material loading container when the cover plate is in the closed state.

[0011] Preferably, as an improvement, an oil collecting groove is arranged below the conveying mechanism, the width between the two groove walls of the oil collecting groove is less than the width of the cover plate, and the cover plate slides on the upper edge of the oil collecting groove when the opening of the material loading container faces downward.

[0012] Preferably, as an improvement, a tension spring is connected between the slide columns on the two arc-shaped clamping plates, or a torsion spring is arranged at the rotating connection between the arc-shaped clamping plates and the material loading plate.

[0013] The advantages of the present scheme are as follows: 1. Effectively reducing food residues in the material loading container: The present scheme cooperates the design of the bottom cleaning assembly and the gravity driving of the cover plate itself, without configuring an additional power drive, and can scrape most of the solid food materials adhering to the wall. When the material loading plate enters the turning section and the return section, the cover plate remains naturally downward under the gravity of the counterweight support block, drives the bottom cleaning assembly to separate from the material loading container quickly, and effectively scrapes the solid food materials originally adhering to the bottom surface and the pouring surface (the side away from the hinge point of the cover plate) of the container to the target packaging bag, thereby effectively controlling the solid food content in each bag within the allowable error range. 2. The present scheme cleverly designs the cover plate to achieve two effects: 1. The solid food materials are always in a closed space during the conveying process, effectively isolating impurities, dust and external environmental pollutants in the air, and cutting off food safety hazards from the conveying link. 2. The bottom cleaning assembly is powered by the structure design of the cover plate, which is always downward in the turning section and the return section under the gravity of the cover plate, thereby providing a power source for the bottom cleaning assembly. Therefore, the present case does not need to set an additional power source, simplifies the device structure, reduces energy consumption, and reduces the risk of failure of electronic components such as motors and sensors.

[0014] 3. Multiple anti-detachment mechanisms: The interlocking state between the arc-shaped clamp and the arc-shaped groove of the material container forms the first mechanical anti-detachment mechanism; while the continuous clamping force provided by the elastic element ensures that the material container is always under stable radial constraint during lifting and conveying, effectively resisting vibration and impact, forming the second dynamic anti-detachment mechanism. This dual anti-detachment protection greatly improves the reliability and safety of equipment operation. Furthermore, the cooperation between the arc-shaped groove and the arc-shaped clamp ensures that the material container will not detach even when inverted.

[0015] 4. Automatic Centering and Rapid Clamping: Compared to traditional methods that rely on bolts for individual tightening or manual pin insertion, this device achieves automatic centering and rapid clamping through its arc-shaped clamping plates and elastic element design. When the material container is placed into the receiving hole formed by the two sets of pressure plates, the container itself compresses the arc-shaped clamping plates, forcing the locking elements at the ends of the plates to slide along the adjusting groove. This overcomes the tension of the elastic element, allowing the receiving hole to expand adaptively. Under the restoring force of the elastic element, the two sets of arc-shaped clamping plates can evenly and synchronously grip the material container, achieving automatic centering and stable clamping, significantly improving loading and unloading efficiency.

[0016] In summary, this solution achieves a comprehensive effect of "precise quantitative control, convenient operation, safety and cleanliness, and stability and reliability" through the solid conveying method of "material carrier + cover plate + bottom cleaning component". It is fully adapted to the solid conveying needs of solid-liquid mixed foods (such as pickled radish and old duck soup) and has high industry application value. Attached Figure Description

DETAILED DESCRIPTION

[0030] The following is further described in detail through specific embodiments: Example 1 A food packaging device containing soup, including a soup filling device and a solid material filling device, substantially as shown in the accompanying drawings Figures 1-10 The solid material filling device includes a transport mechanism, a filling cylinder 5, and a material loading mechanism 2 driven on the transport mechanism. The transport mechanism includes a transport frame 1 and a transmission chain 15 circulatingly driven along the transport frame 1. The transport frame 1 includes a translation section 11, a lifting section 12, a turning section 13, and a return section 14. The transport frame 1 is provided with a sliding groove on both left and right sides. The transmission chain 15 is slidingly connected in the sliding groove and is driven by a motor. The motor is installed on the outside of the translation section 11. The translation section 11 and the turning section 13 are both provided with a rotating shaft, and the rotating shaft is provided with a gear engaged with the transmission chain 15. The motor drives the rotating shaft to rotate, thereby realizing the circulating transportation of the transmission chain 15.

[0031] The loading mechanism 2 comprises a loading container 21 and a loading plate 23 hinged at one end of the transmission chain 15. Specifically, a plurality of connecting pieces are welded on the transmission chain 15, and the loading plate 23 extends downward on both sides to form mounting portions 22, and the connecting pieces are rotationally connected with the mounting portions 22. A pouring cylinder is arranged at the lower side of the left end of the conveying mechanism and used for receiving food in the loading container 21.

[0032] As shown in Figures 3-5 The loading plate 23 is provided with a clamping unit for clamping the loading container 21. Specifically, the clamping unit comprises two arc-shaped clamping plates 231, the upper ends of the two arc-shaped clamping plates 231 are rotationally connected with the loading plate 23, and the lower ends of the two arc-shaped clamping plates 231 are close to each other under the action of elastic tension. The loading plate 23 is provided with arc-shaped adjusting holes 233 corresponding to the arc-shaped clamping plates 231, the arc-shaped adjusting holes 233 are coaxially arranged with the rotation points of the arc-shaped clamping plates 231, the arc-shaped clamping plates 231 are provided with slide columns 232 sliding in the arc-shaped adjusting holes 233, the two slide columns 232 extend downward out of the arc-shaped adjusting holes 233, and a tension spring 234 is fixedly connected between the two slide columns 232. By arranging the tension spring 234 and the arc-shaped adjusting holes 233, loading containers 21 of different sizes and dimensions can be clamped and fixed. In addition, in order to avoid the loading container 21 from being separated from the clamping unit due to external force during conveying, a locking assembly is arranged on each slide column 232. The locking assembly comprises a compression nut and a gasket coaxially connected with the slide column 232, and the locking assembly and the tension spring 234 are both located below the loading plate 23.

[0033] Sliding blocks (not shown in the figure) are fixedly installed at the outer sides of the middle portions of the loading plate 23, and the conveying frame 1 is provided with guide grooves for the sliding blocks to slide at the two side edges of the turnover section 13 and the return section 14, so that the middle portions of the loading plate 23 are limited by the guide grooves at the turnover section 13 and the return section 14, and the turnover is avoided. In addition, the holes for installing the sliding blocks on the loading plate 23 are strip-shaped holes, and the sliding blocks slide on the strip-shaped holes, so as to adapt to the movement space of the conveying frame 1 at different positions. Meanwhile, the entrances of the guide grooves are flared, so that the sliding blocks can more efficiently and accurately enter the guide grooves.

[0034] In addition, the pull plate 235 is fixedly installed on the two arc-shaped clamping plates 231, which can provide clear force points for the operator, so that the pressing plate can be easily and labor-savingly pulled open when the load container 21 needs to be taken out or installed, thereby simplifying the clamping and dismounting steps, shortening the operation time, and being conducive to improving the overall production rhythm. The side of the load plate 23 away from the arc-shaped clamping plate 231 is provided with a roller 236, and the conveying frame 1 is provided with a conveying rail 237 for the movement of the roller 236. Through the design, on the one hand, the wear of the load plate 23 with other components in the conveying process is reduced; on the other hand, the load plate 23 is always in a horizontal state whether it is in the translation section 11 or the lifting section 12, avoiding the food in the load container 21 from being poured out. In order to avoid the interference between the load plate 23 and the conveying rail 237 when the load plate 23 is in the lifting section 12, the load plate 23 located on one side of the conveying rail 237 is provided with a first avoiding opening 31, and the conveying rail 237 is located in the first avoiding opening 31 when conveying in the lifting section 12.

[0035] It is also found in actual use that after the load container 21 turns the food into the pouring cylinder, the food is still attached to the inner wall of the load container 21. For example, when packaging sour radish old duck soup material, part of the inner wall of the load container 21 will still be attached to the sour radish strips / blocks, which will cause the solid content in each food bag to be uneven. In order to solve this problem, the applicant designs the following structure: The load plate 23 is provided with a bottom cleaning unit 3, such as Figures 6-10As shown, the bottom cleaning unit 3 is used to clean the food attached to the bottom of the material container 21, and specifically, the bottom cleaning unit 3 includes two support plates 31 arranged outside the clamping unit. When the material plate 23 is in the translation section 11, the two support plates 31 are respectively located on the left and right sides of the clamping unit. The top of the right support plate 31 is hingedly connected with a cover plate 32, and the cover plate 32 includes a connecting plate 321 and a driving plate 322 which are rotatably connected with each other. The bottom of the connecting plate 321 is provided with a limiting plate, and the free end of the limiting plate is supported on the lower surface of the driving plate 322, so that the driving plate 322 can be flipped upward horizontally without being flipped downward horizontally. The free end of the driving plate 322 is lapped on the left support plate 31. The height of the left support plate 31 is less than one fifth of the height of the material container 21, so as to avoid the food entering between the support plate 31 and the material container 21 during the flipping section 13. In order to enable the left support plate 31 to support the cover plate 32, a counterweight support block 33 is arranged on the free end of the cover plate 32 and lapped on the left support plate 31. Meanwhile, the height of the counterweight support block 33 should not be too long, otherwise the food will be hung on the counterweight support block 33 during the food pouring. Therefore, the height of the counterweight support block 33 and the height of the left support plate 31 need to be within a reasonable range. Through multiple simulation analysis experiments, the height of the left support plate 31 is between 0.2-0.25 of the height of the material container 21, and the counterweight support block 33 is designed as an inclined structure, and the included angle between the counterweight support block 33 and the cover plate 32 is 110°-150°, so as to avoid the food entering between the support plate 31 and the material container 21 and the food being hung on the counterweight support block 33.

[0036] The cover plate 32 is provided with a bottom cleaning assembly 34 for extending into the inside of the material container 21. The bottom cleaning assembly 34 includes a support rod 341 and a scraper 342 fixed on the support rod 341. The support rod 341 is arranged on the cover plate 32, and the scraper 342 is arranged obliquely. When the cover plate 32 is in the closed state, the two ends of the scraper 342 are in contact with the inner wall of the material container 21, the bottom edge of the scraper 342 is in contact with the inner bottom surface of the material container 21, and the high side of the scraper 342 is in contact with the side wall of the material container 21. More preferably, the scraper 342 includes an inclined plate and a vertical plate, and the included angle between the two plates is 20 to 45°. The vertical plate is made of a material containing iron elements, and the right support plate 31 is magnetic. Therefore, when the cover plate 32 is closed, the vertical plate is tightly attached to the right side wall of the material container 21 under the magnetic force of the right support plate 31, so as to reduce the food entering between the scraper 342 and the inner wall of the material container 21.

[0037] As Figure 3As shown, the lower part of the loading container 21 is provided with an annular groove for matching the arc-shaped clamping plate 231 clamping, the inner cavity of the loading container 21 is square structure, and the bottom surface and the left inner wall of the loading container 21 are designed as a circular arc surface, the curvature of the circular arc surface is consistent with the curvature of the bottom edge rotating path of the scraper 342 (i.e. when the cover plate 32 drives the bottom cleaning assembly 34 to rotate around the hinge point, the virtual circumferential surface formed by the movement track of the bottom edge of the scraper 342), which ensures that the scraper 342 is always in contact with the inner wall of the loading container 21 during movement, thereby effectively scraping the food attached to the inner wall.

[0038] When in the turnover section 13 and the return section 14, the loading container 21 is turned over with the transmission chain 15, and the cover plate 32 remains in a natural drooping state under its own weight, so that the bottom cleaning assembly 34 is pulled by the cover plate 32 to overcome the adhesion of the food to the loading container 21, thereby scraping all the food mainly adhered to the bottom surface and the pouring surface (the surface away from the hinge point of the cover plate 32) of the loading container 21.

[0039] In the present scheme, the cover plate 32 and the support plate 31 can effectively cooperate to form a shielding effect on the food through the ingenious design of the counterweight support block 33, and the local pressure of the cover plate 32 and the bottom cleaning assembly 34 on the bottom of the loading container 21 is reduced during the food conveying stage, thereby avoiding local deformation and affecting the bottom cleaning effect. More importantly, the counterweight support block 33 also effectively improves the bottom cleaning efficiency of the bottom cleaning assembly 34, specifically: if the counterweight support block 33 is not set, the cover plate 32 is relatively light, and at the same time the bottom cleaning assembly 34 is pressed by the food, so that in the turnover section 13, the cover plate 32 and the loading container 21 are not easy to separate, and only when the opening of the loading container 21 is large downward, the gravity of the food on the cover plate 32 is applied, and then the two are separated and pull the bottom cleaning assembly 34 to work, although the effect of no residual food in the loading container 21 can be achieved, the response is slow, and occasionally there is still food residue on the cover plate 32. Therefore, by setting the counterweight support block 33, the weight of the free end of the cover plate 32 is increased, and when in the turnover section 13 and the return section 14, the cover plate 32 always remains in a natural drooping state under the action of the gravity of the counterweight support block 33, so that the free end of the cover plate 32 is quickly separated from the loading container 21, which on the one hand reduces the contact between the food and the cover plate 32, and on the other hand reduces the probability of food residue on the cover plate 32, and the cover plate 32 pulls the bottom cleaning assembly 34 to quickly respond, thereby greatly improving the wall scraping efficiency.

[0040] In addition, the lower part of the conveying mechanism is provided with a liquid collecting tank for collecting the liquid dripping from the loading container 21 in the return section 14, the width between the two tank walls of the liquid tank is less than the width of the cover plate 32, and when the opening of the loading container 21 is downward, the cover plate 32 slides on the upper edge of the oil collecting tank.

[0041] The specific implementation method is as follows: The clamping unit clamps and fixes the loading container 21 installed on the loading plate 23, and the transmission chain 15 is started to circulate. The operator covers the connecting plate 321 of the cover plate 32 at the feeding port of the right translation section 11, so that the bottom cleaning assembly 34 enters the loading container 21 and is close to it, and then the operator pours the quantitatively weighed solid food into the loading container 21 and rotates the driving plate 322 to cover the support plate 31, so that the probability of impurities in the air entering the food during the food conveying process can be effectively reduced. When the loading plate 23 enters the lifting section 12, the rollers 236 on the loading plate 23 form an angle with the inclined conveying guide rail 237, the rollers 236 support the loading plate 23 to keep it in a horizontal state, and prevent the food from falling out. When the loading plate 23 enters the turnover section 13 and the return section 14, the cover plate 32 always keeps a natural downward state under the action of the gravity of the counterweight support block 33, so that the free end of the cover plate 32 is quickly separated from the loading container 21, and the bottom cleaning assembly 34 overcomes the adhesion of the food to the loading container 21 under the pulling of the cover plate 32, so that all the food mainly adhered to the bottom surface and the pouring surface (the surface away from the hinge point of the cover plate 32) of the loading container 21 is scraped off.

[0042] Embodiment 2 In order to further improve the scraping rate of the loading container 21, the device is also provided with an auxiliary wall cleaning mechanism 4, and the specific structure is as follows: Figure 11 、 Figure 12 As shown in the figure, the end of the cover plate 32 close to the hinge point is integrally formed with a driving arm 41, the driving arm 41 is hingedly connected with a driving connecting rod 42, the lower end of the driving connecting rod 42 is fixedly connected with a telescopic shaft 43, the telescopic shaft 43 is transversely fixedly connected with a driving sliding block 44, the support plate 31 is vertically provided with a strip hole 45 for sliding of the telescopic shaft 43, and in order to avoid the problem that the driving connecting rod 42 pushes the driving sliding block 44 to swing left and right during driving, vertical through grooves are formed on the front and rear sides of the driving sliding block 44, two slide rails 46 are fixedly installed on the left side wall of the support plate 31, and each slide rail 46 is slidingly connected in the vertical through groove. A support is fixedly installed on the left side wall of the support plate 31 above the vertical through groove, a wall cleaning rod 47 for knocking the upper part of the loading container 21 is rotatably connected to the support, the lower end of the wall cleaning rod 47 is in contact with the driving sliding block 44, and a return spring 48 is fixedly installed between the wall cleaning rod 47 and the support plate 31. In this embodiment, the return spring 48 is a compression spring, and is installed on the upper part of the hinge point of the wall cleaning rod 47.

[0043] The driving surface of the driving slider 44 comprises, from bottom to top, a sliding wedge surface 441, a driving wedge surface 442 and a retaining wedge surface 443. The inclination angle of the sliding wedge surface 441 is consistent with the inclination angle of the upper end of the wall cleaning rod 47 when the upper end is in contact with the support plate 31, so that the two are in surface contact sliding when sliding relative to each other, reducing the degree of wear of point contact sliding. The inclination angle of the driving wedge surface 442 needs to be relatively flat, and the inclination angle is controlled within 5-15°. Within this angle range, on the one hand, during the driving process, the lower end of the wall cleaning rod 47 quickly enters the retaining wedge surface 443 from the sliding wedge surface 441, so that the upper end of the wall cleaning rod 47 is quickly and powerfully impacted by the compression spring to the load container 21, so that the food materials that may be attached to the container wall are loosened and fall out under the action of gravity. On the other hand, when the cover plate 32 is gradually closed, the wall cleaning rod 47 smoothly slides from the retaining wedge surface 443 to the sliding wedge surface 441 through the inclination angle of the driving wedge surface 442. The preferred inclination angle of the embodiment is 8°. The inclination angle of the retaining wedge surface 443 is between 80° and 90°, and the wall thickness is relatively thin, so that the wall cleaning rod 47 has a larger swinging space. In addition, when the cover plate 32 is opened and rotated to the end point (i.e., the driving slider 44 is slid downward to the end point), the top end of the retaining wedge surface 443 is higher than the lower end of the wall cleaning rod 47, so that the wall cleaning rod 47 is always in contact with the retaining wedge surface 443 to avoid disengagement, which is conducive to the successful driving of the wall cleaning rod 47 when the driving slider 44 moves upward.

[0044] The sum of the gravity of the counterweight support block 33, the driving plate 322 and the bottom cleaning assembly 34 is greater than the sum of the gravity of the wall cleaning mechanism 4 and its friction, so that the driving plate 322 smoothly pulls the connecting plate 321 to rotate to drive the wall cleaning mechanism 4 to work during the overturning process.

[0045] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the patent. The protection scope claimed in this application should be subject to the content of its claims, and the specific embodiments described in the specification can be used to explain the content of the claims.
