Description

Technical Field

[0001] The invention relates to the technical field of material packaging, in particular to a multi-state material automatic filling system and method. Background Art

[0002] With the booming development of the catering industry, hot pot, as a popular delicacy, continues to see a rising market demand. In this context, the centralized processing of pre-made hot pot base by condiment processing plants has become the mainstream production model, and the packaging of hot pot base plays a key role in its shelf life, which is directly related to the quality and shelf life of the product.

[0003] In the current hot pot base filling process, there are mainly two methods: semi-automatic filling and fully automatic filling. Semi-automatic packaging mainly uses semi-automatic sauce packaging machines for packaging. Its operation process requires the preparation of individual packaging bags in advance, and the subsequent material receiving and sealing processes are all completed manually. This manual operation mode has many disadvantages. On the one hand, the operator is prone to fatigue due to long-term and high-intensity repetitive material receiving and sealing actions, and it is difficult to maintain an efficient working state. It is not suitable for long-term and large-scale production tasks; on the other hand, manual operation is greatly affected by subjective factors. Different operators have differences in the control of material receiving quantity and sealing tightness, which makes it difficult to ensure product quality consistency, resulting in an increase in the number of defective products.

[0004] The existing fully automatic filling method usually uses a conveying mechanism to transport the packaging bag, and combines it with the upper filling head for automatic filling, such as the device shown in patent publication number CN216862003U. However, when applied to the filling of hot pot soup base, due to the special composition of hot pot soup base, it contains at least oil and sauce. This type of device cannot separate the two during filling. If mixed filling is used, the oil is more fluid than the sauce. During filling, the oil falls into the packaging bag first. When the heavier sauce falls later, the impact force easily causes the oil that falls in first to splash, causing the soup base to overflow the packaging bag, which not only causes a waste of raw materials, but also seriously affects the filling accuracy and product quality, and cannot meet the growing demand for high-quality prefabricated hot pot soup base production. Summary of the invention

[0005] Therefore, in order to solve the above-mentioned deficiencies, the present invention provides a multi-state material automatic filling system and method, which can clamp the packaging bag and open the bag mouth through a multi-station rotating mechanism, and then rotate it to the lower end of the material filling mechanism, and then fill the solid material, semi-solid material and liquid material into the packaging bag in turn, and then seal it through the bag closing mechanism. This filling method not only realizes the automatic filling of multi-state materials, reduces the large amount of labor intensity and errors in manual operation caused by manual filling or semi-automatic filling, but also avoids the liquid material falling into the packaging bag first, causing the liquid material to splash outward when the subsequent solid material or semi-solid material falls, thereby effectively ensuring the filling quality. Therefore, through this automatic filling system and method, not only the filling efficiency is improved, but also the filling quality is guaranteed.

[0006] On the one hand, the present invention provides a multi-state material automatic filling system, the filling system comprises a frame, the frame is rotatably mounted with a multi-station rotating mechanism, the multi-station rotating mechanism comprises at least a fixed disk and a rotating disk, the fixed disk is provided with a bag taking station, a bag supporting station, a material filling station, a bag closing station and a material discharging station in sequence along the rotating direction of the rotating disk, the rotating disk is provided with a clamping assembly for clamping a packaging bag, and the clamped packaging bag is transported to a corresponding station by the rotation of the rotating disk;

[0007] The bag taking station is equipped with a bag taking mechanism for placing a single packaging bag on the multi-station rotating mechanism;

[0008] The bag-holding station is equipped with a bag-holding mechanism for holding open the bag opening of the packaging bag located on the multi-station rotating mechanism;

[0009] The material filling station is equipped with a material filling mechanism, which is used to sequentially fill solid, semi-solid and liquid materials into the packaging bag with the bag opening opened;

[0010] The bag closing station is equipped with a bag closing mechanism, which is used to seal the packaging bag containing the material;

[0011] The discharging station is provided with a discharging conveying mechanism for discharging the sealed packaging bags.

[0012] In order to ensure that materials in different states are filled separately during filling, so as to facilitate the storage and transportation of materials in different states, the material filling station specifically includes a solid material filling area, a semi-solid material filling area and a liquid material filling area arranged in sequence along the rotation direction of the rotating disk, and the material filling mechanism is arranged as a solid material filling mechanism, a semi-solid material filling mechanism and a liquid material filling mechanism corresponding to the position of each filling area. The solid material filling mechanism is an intermittent feeding mechanism, and the semi-solid material filling mechanism is a spiral feeding mechanism. When the multi-station rotating machine When the structure is rotating, the material filling mechanism stops feeding, and keeps feeding when the multi-station rotating mechanism stops. By setting the solid material filling mechanism as an intermittent feeding mechanism, it is convenient to carry out quantitative filling of solid materials, thereby ensuring the quality of filling. By setting the semi-solid material filling mechanism as a spiral feeding mechanism, the sauce can be automatically and evenly conveyed by spiral rotation, further realizing quantitative filling. The liquid material filling mechanism can use a conventional hose plus a liquid pump for conveying and filling because the liquid material has good fluidity, and quantitative filling can also be realized.

[0013] In order to ensure that the bag opening can be sealed after the filling is completed, the bag closing station specifically includes a heat sealing area and a cold sealing area arranged in sequence along the rotation direction of the rotating disk. The bag closing mechanism is configured as a heat sealing mechanism and a cold sealing mechanism corresponding to the positions of the heat sealing area and the cold sealing area. The heat sealing position of the bag opening can be further pressed by the setting of the cold sealing mechanism to avoid the bag opening from separating in the hot melting state, thereby ensuring the sealing effect.

[0014] In order to ensure that the multi-station rotating mechanism is in the correct position during the rotation process, so as to facilitate the clamping, opening, filling and sealing of the packaging bags, the multi-station rotating mechanism is driven by a groove wheel mechanism, and the number of grooves of the groove wheel in the groove wheel mechanism is consistent with the number of stations of the multi-station rotating mechanism. When the multi-station rotating mechanism stops rotating, each station on the multi-station rotating mechanism corresponds to the bag taking mechanism, the bag supporting mechanism, the solid material filling mechanism, the semi-solid material filling mechanism and the liquid material filling mechanism, the heat sealing mechanism, and the cold sealing mechanism.

[0015] In order to facilitate the removal of the packaging bags clamped on the multi-station rotating mechanism, and thus facilitate the bag clamping and bag dropping operations of the multi-station rotating mechanism, a pushing part is provided at the corresponding positions of the fixed plate and the bag taking station and the material discharging station. The pushing part pushes the clamping components of the bag taking station and the material discharging station to move to clamp or release the packaging bags.

[0016] In order to prevent the residual liquid on the outlet of the semi-solid material filling mechanism and the liquid material filling mechanism from dripping into the frame or the outer surface of the packaging bag during the rotation of the multi-station rotating mechanism, thereby affecting the subsequent cleaning and sealing of the packaging bag, a gap is provided between the material filling station and the outlet of the material filling mechanism, and a protective mechanism is movably arranged in the gap to prevent the residual material on the material filling mechanism from dripping onto the packaging bag when the multi-station rotating mechanism is rotating.

[0017] In order to facilitate the discharge of dripping liquid and prevent the liquid from accumulating in the protective mechanism and causing overflow, one end of the protective mechanism is fixedly installed on the fixed plate, and the other end of the protective mechanism is fixedly installed on the material filling mechanism. A movable part for maintaining linear extension and retraction is arranged in the protective mechanism on the fixed plate. When the multi-station rotating mechanism stops, the movable part is in a retracted state, and when the multi-station rotating mechanism rotates, the movable part is in an extended state. When the movable part is in the retracted state, the material filling station remains connected with the discharge port of the material filling mechanism, and the movable part remains disconnected from the protective mechanism installed on the material filling mechanism. When the movable part is in the extended state, the material filling station remains disconnected from the discharge port of the material filling mechanism, and the movable part remains connected with the protective mechanism installed on the material filling mechanism.

[0018] In order to facilitate the staff to control the filling system to control the filling amount of the liquid, the frame is also provided with a controller and a control panel display screen for controlling the start and stop time of the multi-station rotating mechanism and the filling time of the material filling mechanism.

[0019] On the other hand, the present invention also provides a multi-state material automatic filling method, which is implemented by the above-mentioned automatic filling system and includes the following steps:

[0020] S100: The packaging bags conveyed by the bag conveying mechanism are individually taken and placed on the multi-station rotating mechanism by the bag taking mechanism and clamped;

[0021] S200: the multi-station rotating mechanism moves for the first time, moves the clamped packaging bag to the position of the bag support mechanism, and opens the bag opening through the bag support mechanism;

[0022] S300: the multi-station rotating mechanism moves for the second time, and moves the packaging bag with the bag opening opened to the solid material filling mechanism for feeding the solid material;

[0023] S400: the multi-station rotating mechanism moves for the third time, and moves the packaging bag with solid materials to the semi-solid material filling mechanism for the semi-solid material to be added;

[0024] S500: the multi-station rotating mechanism moves for the fourth time, and moves the packaging bag with the semi-solid material to the liquid material filling mechanism for liquid material feeding;

[0025] S600: the multi-station rotating mechanism moves for the fifth time, and moves the packaging bag with the liquid material to the heat sealing mechanism for heat pressure sealing;

[0026] S700: The multi-station rotating mechanism moves for the sixth time, moving the heat-sealed packaging bag to the cold-sealing mechanism for cold-pressing sealing;

[0027] S800: The multi-station rotating mechanism moves for the seventh time. After the cold-sealed packaging bag is moved to the discharge conveying mechanism, the multi-station rotating mechanism releases the bag opening, and the bag naturally falls to the discharge conveying mechanism and is transported out.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. Realize automatic filling of multi-state materials: The automatic filling system can clamp, open and rotate the packaging bags through the multi-station rotation mechanism, bag taking mechanism and bag supporting mechanism. Combined with the material filling mechanism, it can automatically complete the filling of solid materials, semi-solid materials and liquid materials in sequence. There is no need to manually switch materials or operate the filling process, which greatly improves the degree of production automation and adapts to the complex production needs of hot pot base.

[0030] 2. Reduce labor intensity: The automatic filling system and automatic filling method can replace manual filling or semi-automatic filling, reduce long-term repetitive labor, reduce the burden on workers, reduce labor costs, and save labor expenses for enterprises.

[0031] 3. Reduce manual operation errors: The automatic filling system and automatic filling method can avoid problems such as inaccurate material filling volume and loose bag sealing caused by factors such as manual operation proficiency and fatigue, improve product consistency and stability, and ensure product quality.

[0032] 4. Avoid material splashing: The automatic filling system and automatic filling method effectively prevent the liquid material from splashing after being impacted by the subsequent solid or semi-solid material after entering the bag, through the filling order of solid and semi-solid materials first and then liquid materials, ensuring that the materials can fall accurately into the packaging bag, reducing material waste and improving the neatness and accuracy of filling.

[0033] 5. Improve filling efficiency: The automatic filling system and automatic filling method use a multi-station rotating mechanism to quickly circulate packaging bags, the material filling mechanism to efficiently unload materials, and the bag closing mechanism to seal in time. The overall process is coherent and smooth, which greatly shortens the filling time of a single packaging bag and produces more qualified products per unit time.

[0034] 6. Ensure filling quality: The automatic filling system and the specific structure of the solid material filling mechanism and the semi-solid material filling mechanism can quantitatively fill solid and semi-solid materials. Combined with the heat sealing mechanism and the cold sealing mechanism, it can effectively ensure the sealing of the bag mouth, comprehensively guarantee product quality, ensure that the weight, ingredient ratio and packaging appearance of each bag of hot pot base meet high standards, and enhance product market competitiveness.

[0035] 7. Easy to promote in the industry: With its high efficiency and high quality, the automatic filling system and method are in line with the needs of large-scale industrial production of hot pot base, reducing the production cost and management difficulty of the enterprise, and are easy to popularize and apply in the entire hot pot base industry, thus promoting industrial upgrading.

[0072] The technical solution of the present invention is further described in detail below through specific embodiments and in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0073] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0074] As described in the background technology, the existing hot pot base filling adopts a semi-automatic filling method, which is time-consuming and labor-intensive, and the efficiency and quality cannot be guaranteed. Some fully automatic filling equipment usually mixes the sauce and oil of the hot pot base for filling. This method is not conducive to the storage and transportation of the sauce and oil. At the same time, it is easy to cause oil splashing during the filling process, which not only causes waste but also affects the subsequent sealing, making it difficult to ensure the quality of the filling.

[0075] Based on the above reasons, the present invention provides the following embodiments.

[0076] Embodiment 1:

[0077] Please see attached Figure 1 ~Attached Figure 5 A multi-state material automatic filling system includes a frame 100, on which a multi-station rotating mechanism 300 is rotatably mounted, and the multi-station rotating mechanism 300 includes at least a fixed disk 305 and a rotating disk 304, on which a bag taking station, a bag supporting station, a material filling station, a bag closing station and a material discharging station are sequentially arranged along the rotation direction of the rotating disk 304, and the rotating disk 304 is provided with a clamping assembly 306 for clamping a packaging bag, and the clamped packaging bag is transported to a corresponding station by the rotation of the rotating disk 304;

[0078] The bag taking station is equipped with a bag taking mechanism 500 for placing a single packaging bag 1400 on the multi-station rotating mechanism 300;

[0079] The bag-opening station is equipped with a bag-opening mechanism 1200 for opening the bag opening of the packaging bag 1400 on the multi-station rotating mechanism 300;

[0080] The material filling station is equipped with a material filling mechanism, which is used to sequentially fill solid, semi-solid and liquid materials into the packaging bag 1400 with the bag opening opened;

[0081] The bag closing station is equipped with a bag closing mechanism, which is used to seal the packaging bag 1400 containing the material;

[0082] The discharging station is provided with a discharging conveying mechanism 1100 for discharging the sealed packaging bags 1400 .

[0083] In this embodiment, the bag closing station specifically includes a heat sealing area and a cold sealing area arranged in sequence along the rotation direction of the rotating disk 304. The bag closing mechanism is configured as a heat sealing mechanism 900 and a cold sealing mechanism 1000 corresponding to the positions of the heat sealing area and the cold sealing area. Through the setting of the cold sealing mechanism 1000, the heat sealing position of the bag opening can be further pressed to avoid the bag opening from separating in the hot melting state, thereby ensuring the sealing effect.

[0084] The frame 100 is also provided with a controller and a control panel display screen 200 for controlling the start and stop time of the multi-station rotating mechanism 300 and the filling time of the material filling mechanism.

[0085] The controller is equipped with a conventional PLC control system, which is convenient for overall control of the entire filling system and for staff to adjust at any time. This control method refers to the existing PLC control principle and will not be repeated here.

[0086] Embodiment 2:

[0087] Please refer to the attached Fig. 9 Based on the first embodiment, in order to facilitate the individual conveyance of the stacked packaging bags, so that the bag taking mechanism can take the individually conveyed packaging bags and place them on the multi-station rotating mechanism 300 for filling, the material bag conveying mechanism 400 is also included. The material bag conveying mechanism 400 is arranged outside the bag taking mechanism 500. The material bag conveying mechanism 400 specifically includes a first support body 401, one end of which is close to the multi-station rotating mechanism 300;

[0088] Two clamping plates 402 are arranged opposite to each other on one side above the first support body 401 and away from the multi-station rotating mechanism 300, and are used to limit and clamp the stacked packaging bags 1400;

[0089] The conveying belt 405 is rotatably disposed above the first support body 401 to keep in contact with the bottom packaging bag 1400 and convey it;

[0090] The inclined plate 404 is obliquely disposed above the first support body 401 to maintain a gap with the top of the first support body 401 for a single packaging bag 1400 to pass through;

[0091] The pressing roller 406 is rotatably disposed on one side of the first support body 401 close to the multi-station rotating mechanism 300 and is used to press the packaging bag 1400 for transportation.

[0092] Furthermore, the conveyor belt 405 adopts a conventional belt conveyor structure, and is used to horizontally convey horizontally placed packaging bags.

[0093] The method for conveying stacked packaging bags in this embodiment is as follows:

[0094] The staff places the stacked packaging bags 1400 on the first support body 401 between the two pallets 402 and keeps the bottom in contact with the conveyor belt 405. When the multi-station rotating mechanism 300 moves, the conveyor belt 405 moves at the same time, driving the bottom packaging bag 1400 to pass through the gap of the inclined plate 404 and move to the other end of the inclined plate 404. After being compressed and conveyed to the end position by the clamping roller 406, it waits for the bag picking mechanism 500 to pick up the bag, completing the single conveying process of the packaging bag.

[0095] Embodiment 3:

[0096] Based on Example 2, in order to facilitate the adjustment of the distance between the two card plates 402, thereby facilitating the placement of packaging bags of different sizes, the bottom of the two card plates 402 passes through the first support body 401 to maintain linear sliding, and a screw is rotatably arranged inside the first support body 401. The threads at both ends of the screw are reverse threads and are respectively threadedly connected to the two card plates 402. Either end of the screw passes through the outside of the first support body 401 and a handwheel 403 is arranged at the end. The screw is driven to rotate by the handwheel 403 to achieve the adjustment of the distance between the two card plates 402. This is a conventional connection structure in the mechanical field, and the specific structure and transmission method are not shown in detail in this application.

[0097] Embodiment 4:

[0098] Please see attached Fig.10 Based on Example 2, in order to facilitate the single conveyed packaging bag to be taken and placed on the multi-station rotating mechanism for clamping, so as to facilitate the subsequent filling operation, the bag taking mechanism 500 includes a support plate 501, which is arranged between the bag conveying mechanism 400 and the multi-station rotating mechanism 300;

[0099] A first driving cylinder 502, one end of which is rotatably connected to the support plate 501, and the other end of which is rotatably connected to the middle of the swing arm 503;

[0100] A swing arm 503, one end of which is rotatably mounted on the support plate 501, and the other end of which is connected to one end of the connecting arm 504;

[0101] A support arm 506, one end of which is fixed to the other end of the connecting arm 504, and the other end of which is fixed with a fixing clamp 508;

[0102] The second driving cylinder 505 has one end rotatably mounted on the support arm 506, and the other end is hinged to a movable clamp 507 rotatably arranged on the outer end of the support arm 506. When the second driving cylinder 505 is extended or retracted, it drives the movable clamp 507 to move closer to or away from the fixed clamp 508, thereby clamping the packaging bag 1400.

[0103] The method for clamping and placing the packaging bag in this embodiment is as follows:

[0104] The first driving cylinder 502 extends out, driving the two clamps on the swing arm 503 and the support arm 506 to be at both ends of the bag opening of a single packaging bag 1400 at the end of the bag conveying mechanism 400, and then the second driving cylinder 505 retracts, driving the movable clamp 507 to approach the fixed clamp 508, thereby clamping the bag opening of the packaging bag 1400, and finally the first driving cylinder 502 retracts, driving the swing arm 503 and the clamped packaging bag 1400 to move to the clamping claws of the corresponding station on the multi-station rotating mechanism 300, and the second driving cylinder 505 extends out to release the packaging bag 1400, and the packaging bag can be clamped by the clamping assembly of the corresponding station on the multi-station rotating mechanism 300, thereby realizing the clamping and placement of a single packaging bag.

[0105] Embodiment 5:

[0106] Please see attached Figure 6 Based on the fourth embodiment, in order to facilitate the clamping and opening of the packaging bag clamped and placed by the bag taking mechanism 500, and to facilitate the rotation to the material filling mechanism and the bag closing mechanism for material filling and sealing, the multi-station rotating mechanism 300 specifically includes a supporting column 303, the bottom of which is installed in the frame 100 and a rotatable shaft is provided inside the supporting column 303;

[0107] The first driving motor 301 is disposed in the frame 100 and drives the shaft inside the supporting column 303 to rotate through the transmission mechanism 302;

[0108] The rotating disk 304 is disposed on the top of the supporting column 303 and is driven to rotate by a rotating shaft;

[0109] The fixed disk 305 is coaxially arranged above the rotating disk 304 and remains fixed;

[0110] A plurality of clamping assemblies 306 are installed in a circumferential distribution above the rotating disk 304 for clamping and releasing the packaging bag 1400 .

[0111] Furthermore, the rotating shaft can be a hollow rotating shaft, in which a support rod is fixed by a bearing, the fixed disk 305 is fixed to the top of the support rod, and the rotating disk 304 is arranged on the outer surface of the top of the hollow rotating shaft, and the rotating disk 304 is driven to rotate by the rotation of the hollow rotating shaft.

[0112] In this embodiment, the transmission mechanism 302 is a sheave mechanism, and the number of notches of the sheave in the sheave mechanism is consistent with the number of workstations. When the multi-station rotating mechanism 300 is stopped, each clamping assembly 306 corresponds to a workstation position.

[0113] Please see attached Figure 7 and attached Figure 8In this embodiment, the clamping assembly 306 is composed of two groups of fixed clamping blocks 3061 which are symmetrically arranged in the left and right directions. One end of the two fixed clamping blocks 3061 is respectively connected to the telescopic part of the cylinder 3062, and the other end is arranged opposite to each other and maintains the outer end to form a clamping part. When the cylinder 3062 is extended or retracted, the two fixed clamping blocks 3061 remain away from or close to each other. Movable clamping blocks 3063 are hinged above the two fixed clamping blocks 3061, and one end of the two movable clamping blocks 3063 is extended upward to provide a pushing head, and the other end is provided with a clamping head that is combined with and separated from the clamping part of the fixed clamping block 3061. The movable clamping block 3063 keeps the middle part hinged on the fixed clamping block 3061 and is provided with a torsion spring at the hinge. The torsion spring is used to make the clamping part of the fixed clamping block 3061 and the clamping head of the movable clamping block 3063 in a clamping state.

[0114] In this embodiment, in order to facilitate the clamping and loosening of the packaging bags at the corresponding stations, a pushing part is provided at the corresponding positions of the fixed plate 305 and the bag taking station and the material discharging station. The pushing part pushes the clamping assembly 306 of the bag taking station and the material discharging station to move to clamp or loosen the packaging bags.

[0115] For further information, please see the attached Figure 6 The pushing part is a driving arm 307 and a pushing plate 308 fixedly arranged on the fixed plate 305. The driving arm 307 maintains linear extension and retraction to drive the pushing plate 308 to push the pushing head of the movable clamping block 3063 to move, so that the movable clamping block 3063 can be rotated to realize the taking and placing of the packaging bag.

[0116] The specific method is: the driving arm 307 in the pushing part extends out, driving the pushing plate 308 to move, thereby pushing the pushing head of the movable clamping block 3063, causing the movable clamping block 3063 to rotate, thereby squeezing the torsion spring to make the clamping part of the fixed clamping block 3061 and the clamping head of the movable clamping block 3063 in a loose state, so as to facilitate the taking and placing of the packaging bag.

[0117] By the attached Figure 6 It can be seen that there are 8 clamping assemblies 306 in total, thus forming 8 workstations, each of which corresponds to a bag taking mechanism 500, a bag supporting mechanism 1200, a solid material filling mechanism 600, a semi-solid material filling mechanism 700, a liquid material filling mechanism 800, a heat sealing mechanism 900, a cold sealing mechanism 1000, and a material discharging and conveying mechanism 1100.

[0118] The method for clamping and placing the packaging bag in this embodiment is as follows:

[0119] The pusher at the corresponding station of the bag taking mechanism 500 moves, and the push plate 308 is extended through the driving arm 307, thereby pushing the movable clamping block 3063 to rotate, so that the clamping assembly is in a loose state (see the attached Figure 8), and then the bag taking mechanism 500 moves the clamped packaging bag 1400 to the position of the clamping assembly (this clamping movement method can be referred to Example 4), keeping the two sides of the bag opening between the two clamping blocks, and then the driving arm 307 retracts, the movable clamping block 3063 loses the thrust of the push plate 308, and the movable clamping block 3063 rotates in the opposite direction under the elastic action of the torsion spring, so that the packaging bag 1400 can be clamped, and finally the bag taking mechanism 500 releases the packaging bag 1400, and the packaging bag can be driven to move by the rotation of the multi-station rotating mechanism 300, so as to facilitate the subsequent bag opening, filling and sealing.

[0120] Embodiment 6:

[0121] Please see attached Fig.13 and attached Fig.14 Based on Example 5, in order to facilitate opening the bag mouth of the packaging bag on the clamping assembly for subsequent filling, the bag support mechanism 1200 specifically includes a second support rod 1201, the bottom of which is fixed in the frame 100;

[0122] The second protection box 1202 is arranged on the top of the second support rod 1201;

[0123] Two second sliding rods 1203 are arranged in parallel and vertically distributed and pass through the second protection box 1202 to keep sliding in a straight line;

[0124] The negative pressure heads 1204 are respectively arranged on the inner sides of the ends of the two second sliding rods 1203 and are arranged opposite to each other;

[0125] Two second sleeves 1205 are arranged in the second protection box 1202 to facilitate the second sliding rod 1203 to pass through and maintain linear sliding;

[0126] The second rotating head 1206 is rotatably disposed in the second protection box 1202 and between the two second sliding rods 1203;

[0127] A gear is disposed on the second rotating head 1206 , and a rack is disposed on the surface of the second sliding rod 1203 facing the second rotating head 1206 , and the gear and the rack are meshed.

[0128] Furthermore, the negative pressure head 1204 may be a vacuum suction cup, which is convenient for adsorbing a packaging bag with a smooth surface and pulling it outward to open the bag opening.

[0129] The method for opening the packaging bag in this embodiment is as follows:

[0130] First, the cylinder 3062 in the clamping assembly 306 retracts, driving the two fixed clamping blocks 3061 to move closer, thereby squeezing the clamped packaging bag inward to facilitate the opening of the bag. Then, the second rotating head 1206 rotates, driving the two second sliding rods 1203 to slide, so that the two negative pressure heads 1204 move closer, maintain contact with and adsorb on the outer side of the bag opening of the packaging bag 1400, and finally, the second rotating head 1206 rotates in the opposite direction, and the two negative pressure heads 1204 move away and drive the bag opening of the packaging bag to open outward. Under the clamping force of the clamping assembly 306, the negative pressure head 1204 separates from the packaging bag, thereby achieving the opening of the bag.

[0131] Embodiment 7:

[0132] Please see attached Fig.11 and attached Fig.12 , based on Example 5, in order to facilitate sealing of the packaging bag, the heat sealing mechanism 900 includes a first support rod 901, the bottom of which is fixed in the frame 100;

[0133] A first protection box 902 is disposed on the top of the first support rod 901;

[0134] Two first sliding rods 903 are arranged in parallel and vertically distributed and pass through the first protection box 902 to maintain linear sliding;

[0135] The hot pressing sealing heads 904 are respectively arranged on the inner sides of the ends of the two first sliding rods 903 and are arranged opposite to each other;

[0136] Two first sleeves 907 are arranged in the first protection box 902 to facilitate the first sliding rod 903 to pass through and maintain linear sliding;

[0137] A first rotating head 908 is rotatably disposed in the first protection box 902 and between the two first sliding rods 903;

[0138] A gear is disposed on the first rotating head 908 , and a rack is disposed on the surface of the first sliding rod 903 facing the first rotating head 908 , and the gear and the rack are meshed.

[0139] In this embodiment, a flow channel is provided in the hot pressing sealing head 904, and the flow channel facilitates the connection of the steam pipes 905 at both ends.

[0140] In this embodiment, the first rotating head 908 in the first protective box 902 is also connected to a control circuit 906 , and the control circuit 906 facilitates the controller to control the first rotating head 908 to rotate forward and reverse.

[0141] The structures of the heat sealing mechanism 900, the cold sealing mechanism 1000 and the bag-holding mechanism 1200 are similar, and the only difference is that the parts in contact with the packaging bag are different, wherein the heat sealing mechanism 900 is a hot pressure sealing head 904, the cold sealing mechanism 1000 is a cold pressure sealing head with an arc surface, and the bag-holding mechanism 1200 is a negative pressure head 1204, and the sealing process is the same as the operating principle of the bag-holding mechanism 1200, which will not be repeated here.

[0142] Embodiment 8:

[0143] Please see attached Fig.15 and attached Fig.16 Based on Example 1, in order to ensure that materials in different states are filled separately during filling, so as to facilitate the storage and transportation of materials in different states, in this embodiment, the material filling station specifically includes a solid material filling area, a semi-solid material filling area and a liquid material filling area arranged in sequence along the rotation direction of the rotating disk, and the material filling mechanism is configured as a solid material filling mechanism 600, a semi-solid material filling mechanism 700 and a liquid material filling mechanism 800 corresponding to the positions of each filling area. The solid material filling mechanism 600 is an intermittent feeding mechanism, and the semi-solid material filling mechanism 700 is a spiral feeding mechanism. The feeding mechanism, when the multi-station rotating mechanism 300 is rotating, the material filling mechanism stops feeding, and keeps feeding when the multi-station rotating mechanism 300 stops. By setting the solid material filling mechanism as an intermittent feeding mechanism, it is convenient to quantitatively fill the solid material, thereby ensuring the quality of filling. By setting the semi-solid material filling mechanism as a spiral feeding mechanism, the sauce can be automatically and evenly conveyed by spiral rotation, further realizing quantitative filling. The liquid material filling mechanism can use a conventional hose plus a liquid pump for conveying and filling because the liquid material has good fluidity, and quantitative filling can also be achieved.

[0144] In this embodiment, the solid material filling mechanism 600 includes a third driving cylinder 601, which is fixed in the frame 100 to maintain a vertical installation;

[0145] The feeding cone 602 is fixed on the outer side of the telescopic part of the third driving cylinder 601 to keep moving up and down;

[0146] The material distributing barrel 603 is arranged above the frame 100 and has a material distributing plate 604 rotatably mounted inside;

[0147] The conical hopper 605 is arranged at the top of the frame 100 and is coaxial with the feeding conical cylinder 602 .

[0148] Furthermore, the bottom of the feeding cone 602 is a small end. When the feeding cone 602 moves to the lowermost end, its bottom is inserted into the open packaging bag. When the feeding cone 602 moves to the uppermost end, the top is sleeved on the outside of the conical hopper 605.

[0149] A through hole 607 connected to the conical hopper 605 is formed at the bottom of one end of the dividing barrel 603, and the dividing disc 604 is rotatably set at the center of the dividing barrel 603 and is provided with a plurality of circumferentially distributed dividing plates on the outside, and the dividing barrel 603 is divided into a plurality of equal-sized placement areas by the dividing plates, so as to facilitate the quantitative placement of solid materials (such as dried chilies). At the same time, combined with the rotation of the dividing disc 604, the solid materials in the placement areas are pushed to the through hole 607, and finally fall into the conical hopper 605 to realize the quantitative unloading and filling of the solid materials.

[0150] Furthermore, in order to increase the discharge speed of the solid material, a lifting cylinder 606 is provided at the top center of the conical hopper 605. The solid material in the conical hopper 605 can be quickly pushed into the packaging bag by extending the lifting cylinder 606, thereby realizing a fast discharge process.

[0151] It is worth noting that the solid material filling mechanism 600 can also be set as other feeding mechanisms, such as a bucket elevator, a groove wheel feeding mechanism, etc., which can realize intermittent quantitative feeding.

[0152] At the same time, the solid material filling mechanism 600 can also be externally connected to a lifting conveyor or a bucket elevator to facilitate automatic feeding into the material distribution barrel 603.

[0153] In this embodiment, the semi-solid material filling mechanism 700 is two vertically distributed spiral tubes (i.e., a rotating spiral is provided in the tube, and feeding is achieved by the rotation of the spiral), and the connection between them is maintained by an inclined tube. Any one of the spiral tubes is kept vertically placed and fixed by a support column in the frame 100. Its bottom is open and corresponds to the station of the multi-station rotating mechanism 300. The other spiral tube can be arranged horizontally to facilitate connection with an external mixer or mixing tank or hopper, thereby continuously conveying semi-solid material (i.e., sauce) into the spiral tube.

[0154] In this embodiment, the liquid material filling mechanism 800 can be a liquid adding hose, which is fixed by a support column in the frame 100, keeping the liquid outlet of the hose above the station of the multi-station rotating mechanism 300, and the other end of the liquid adding hose is connected to an external oil container and a pump body is set to facilitate automatic control for automatic liquid addition.

[0155] Since oil and sauce will solidify at room temperature, a heating device needs to be arranged outside the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 to avoid blockage caused by solidification and to ensure the fluidity of the liquid.

[0156] In this embodiment, when the solid material filling mechanism 600 is an intermittent feeding mechanism, the time required for the solid material filling mechanism 600 to fill the material isT 1 Since the solid material filling mechanism 600 fills the material with solid material and the filling amount is fixed (determined by the actual filling amount), T 1 The most influential factors are the rotation speed of the material distribution plate 604, the falling speed of the solid material from the material distribution barrel 603 to the conical hopper 605, and the extension speed of the lifting cylinder 606 to quickly push the material in the conical hopper 605 into the package. T 1 The controllable factors are the driving motor and its transmission mechanism for driving the rotation speed of the material distribution plate 604 and the extension speed of the lifting cylinder 606.

[0157] When the semi-solid material filling mechanism 700 is a spiral feeding mechanism, the time required for the semi-solid material filling mechanism 700 to fill the material is T 2 ,in T 2 It is mainly determined by the following formula:

[0158] ;

[0159] in, M It is the filling volume of semi-solid materials, which is determined by the staff according to the actual filling volume, and the unit is m 3 ;

[0160] Q 2 is the conveying volume of the spiral tube per unit time, in m 3 / h;

[0161] When the spiral feeding mechanism feeds, its conveying capacity can be calculated by the following formula:

[0162] ;

[0163] in, D is the spiral diameter, in m, S is the pitch, in m, n Indicates the speed in r / min. ρ Indicates the bulk density of the material in t / m 3 , v Indicates the average linear speed of material during transportation, in m / s;

[0164] From the above formula, it can be concluded that when the semi-solid material filling mechanism 700 conveys the semi-solid material, the influence T 2 The controllable factor is the speed of the screw. n .

[0165] The time required for the liquid material filling mechanism 800 to fill the material is T 3 ,in T 3 It is mainly determined by the following formula:

[0166] ;

[0167] in, K It is the filling volume of liquid materials, which is determined by the staff according to the actual filling volume, and the unit is m 3 , Q 3 is the flow rate, in m 3 / s,

[0168] When the liquid flows in the pipe, its flow rate is calculated by the following formula:

[0169] ;

[0170] in, u is the flow velocity in m / s, A is the cross-sectional area of ​​the pipe, in m 2 ;

[0171] From the above formula, it can be concluded that when the liquid material filling mechanism 800 conveys semi-solid materials, the influence T 3 The controllable factor is the flow rate of the liquid u , and the factors that affect the liquid flow rate are the output power of the liquid pump and the viscosity of the liquid.

[0172] Furthermore, when T 1 ≈ T 2 ≈ T 3 and as small as possible, the material filling mechanism has the highest filling efficiency, and the method of improving the filling efficiency can refer to the above T 1 , T 2 , T 3 controllable factors.

[0173] Embodiment 9:

[0174] Please see attached Fig.17 ~Attached Fig.19Based on Example 8, since there is a gap between the material filling station and the discharge port of the material filling mechanism, especially when the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 stop filling, the residual liquid at the pipe mouth may fall onto the rotating disk, that is, the liquid may fall onto the outside of the packaging bag or into the frame. Therefore, a protective mechanism 1300 is movably arranged in the gap to prevent the residual material on the material filling mechanism from dripping onto the packaging bag 1400 when the rotating disk rotates.

[0175] In this embodiment, one end component of the protective mechanism 1300 is fixedly installed on the fixed plate 305, and the other end component of the protective mechanism 1300 is fixedly installed on the material filling mechanism. A movable part for maintaining linear extension is provided on the protective mechanism 1300 on the fixed plate 305. When the multi-station rotating mechanism 300 stops, the movable part retracts, and when the multi-station rotating mechanism 300 rotates, the movable part extends. When the movable part retracts, the material filling station and the discharge port of the material filling mechanism remain connected, and the movable part remains disconnected from the protective mechanism 1300 installed on the material filling mechanism. When the movable part extends, the material filling station is separated from the discharge port of the material filling mechanism, and the movable part remains connected to the protective mechanism 1300 installed on the material filling mechanism.

[0176] Furthermore, the components of the protection mechanism 1300 installed on the fixed plate 305 include a fourth driving cylinder 1301, which is installed on the fixed plate 305 and keeps the telescopic direction pointing to the middle position between the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800;

[0177] The receiving plate 1302 is installed on the telescopic end of the fourth driving cylinder 1301 and has a receiving groove 1303 at the top corresponding to the discharge port of the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800;

[0178] A water-absorbing material (such as a sponge) is placed in the receiving groove 1303 .

[0179] The components of the protection mechanism 1300 installed on the material filling mechanism include a support plate 1304 and an oil drain pipe 1305. The support plate 1304 is fixed on the support columns of the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800. The oil drain pipe 1305 is arranged on the side wall of the support plate 1304. A through hole for the oil drain pipe 1305 to pass through is opened on the inner wall of the accommodating groove 1303 of the receiving plate 1302. The oil drain pipe 1305 is kept in communication with the oil drain pipe preset at the bottom of the support plate 1304.

[0180] Furthermore, in order to prevent the fourth driving cylinder 1301 from colliding with the dripping liquid during the extension process, thereby knocking the liquid into the frame 100, a visual detection device is provided on the opposite surfaces of the receiving plate 1302 and the support plate 1304. The visual detection device is adapted to the path of the liquid drop and keeps the detection direction perpendicular to the liquid drop direction. When the liquid is falling, the light emitted by the visual detection device is blocked by the liquid, indicating that the liquid is dripping. When the liquid stops falling, the light emitted by the visual detection device is not blocked, indicating that the liquid is not dripping.

[0181] Because the protection mechanism 1300 is installed on both sides of the lower ends of the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800, when the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 are in the filling time T 2 , T 3 When the light emitted by the visual detection device is always blocked by the liquid, the fourth driving cylinder 1301 is controlled by the control system to be in a retracted state. When the filling time is reached T 2 , T 3 (the time after that shall prevail), the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 both stop feeding, and the light emitted by the visual detection device is in the time period t When the fourth driving cylinder 1301 is not blocked by the dripping liquid within a period of time (determined by the time required for the fourth driving cylinder 1301 to be fully extended, such as the time required for the fourth driving cylinder 1301 to be fully extended is 1 second, then the time period is 1 second), after the next dripping of the liquid at the bottom material port of the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 (the subsequent dripping time shall prevail), the fourth driving cylinder 1301 is quickly extended to push the receiving plate 1302 to move to the gap between the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 and the bag opening of the packaging bag 1400, and keep the oil drain pipe 1305 inserted into the water-absorbing material placed in the receiving groove 1303, thereby achieving the purpose of protection and effectively avoiding the fourth driving cylinder 1301 from colliding with the dripping liquid during the extension process.

[0182] The protection process of this embodiment is as follows:

[0183] When the multi-station rotating mechanism 300 is pre-rotated after filling is completed, the fourth driving cylinder 1301 extends out to push the receiving plate 1302 to move, so that the receiving tank 1303 is below the discharge port of the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800. At this time, the oil discharge pipe 1305 passes through the through hole of the receiving tank 1303 and is inserted into the receiving tank 1303 to squeeze the water-absorbing material. During the squeezing process, the liquid in the water-absorbing material enters the oil discharge pipe 1305 and is discharged from the oil discharge pipe. At the same time, the semi-solid material filling mechanism 700 and the liquid material filling mechanism 800 are The material dripping from the state material filling mechanism 800 drops on the water-absorbing material in the receiving tank 1303 to avoid splashing outward. When filling is carried out, the multi-station rotating mechanism 300 stops. At this time, the fourth driving cylinder 1301 retracts to drive the receiving plate 1302 to retract, and the oil drain pipe 1305 is separated from the water-absorbing material in the receiving tank 1303. The water-absorbing material returns to its original position under the action of elasticity. This process can absorb the liquid at the end of the oil drain pipe 1305 to prevent the liquid that has not flowed into the pipe at the end of the oil drain pipe 1305 from dripping into the frame 100.

[0184] Embodiment 10:

[0185] Please see attached Fig. 20 This embodiment provides a method for automatically filling multi-state materials, which uses the multi-state material automatic filling system described in Embodiments 1 to 9 for filling, and includes the following steps:

[0186] S100: The bag taking mechanism 500 takes and places the packaging bags 1400 conveyed by the bag conveying mechanism 400 individually onto the multi-station rotating mechanism 300 and clamps them.

[0187] Specifically:

[0188] The pusher at the bag taking station moves, and the push plate 308 is extended through the driving arm 307, thereby pushing the movable clamping block 3063 to rotate, so that the clamping assembly is in an open state (see the attached Figure 8 ), the first driving cylinder 502 extends out, driving the two clamping plates on the swing arm 503 and the support arm 506 to be at both ends of the bag opening of a single packaging bag 1400 at the end of the bag conveying mechanism 400, and the second driving cylinder 505 retracts, driving the movable clamping plate 507 to approach the fixed clamping plate 508, thereby clamping the bag opening of the packaging bag 1400, and the first driving cylinder 502 retracts, driving the swing arm 503 and the clamped packaging bag 1400 to move to the clamping assembly of the corresponding station on the multi-station rotating mechanism 300, keeping the two sides of the bag opening between the two clamping blocks, and then the driving arm 307 retracts, the movable clamping block 3063 loses the thrust of the push plate 308, and the movable clamping block 3063 rotates in the opposite direction under the elastic action of the torsion spring, so that the packaging bag 1400 can be clamped, and the second driving cylinder 505 extends out and releases the packaging bag 1400.

[0189] S200: The multi-station rotating mechanism 300 moves for the first time, moves the packaging bag after the bag grabbing and clamping to the position of the bag supporting mechanism 1200, and opens the bag opening through the bag supporting mechanism 1200.

[0190] Specifically:

[0191] The first driving motor 301 is started for a predetermined time, driving the transmission mechanism 302 to move once, and driving the rotating disk 304 to move synchronously once under the transmission action of the internal rotating shaft of the supporting column 303, so that the packaging bag 1400 at the bag taking station moves to the bottom of the bag supporting mechanism 1200;

[0192] Subsequently, the cylinder 3062 in the clamping assembly 306 retracts, driving the two fixed clamping blocks 3061 to move closer, thereby squeezing the clamped packaging bag inward to facilitate the opening of the bag. The second rotating head 1206 rotates, driving the two second sliding rods 1203 to slide, so that the two negative pressure heads 1204 move closer, maintain contact with and adsorb on the outer side of the bag opening of the packaging bag 1400, and finally the second rotating head 1206 rotates in the opposite direction, and the two negative pressure heads 1204 move away and drive the bag opening of the packaging bag to open outward. Under the clamping force of the clamping assembly 306, the negative pressure head 1204 separates from the packaging bag, thereby achieving the opening of the bag.

[0193] S300: the multi-station rotating mechanism 300 moves for the second time, and moves the packaging bag with the bag opening opened to the solid material filling mechanism 600 for feeding the solid material.

[0194] Specifically:

[0195] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0196] When solid materials are added, the third driving cylinder 601 extends out, driving the feeding cone 602 to descend and keep the bottom inserted into the opening of the packaging bag 1400, and then the dividing plate 604 is driven by the external groove wheel mechanism to move once, so that the area of ​​the two adjacent dividing plates of the dividing plate 604 is at the position of the through hole 607 of the dividing barrel 603. At this time, the solid material between the two adjacent dividing plates of the dividing plate 604 loses its supporting force, passes through the through hole 607 and falls into the conical hopper 605, and falls into the feeding cone 602 under the action of gravity. The lifting cylinder 606 extends out to quickly push the solid material in the feeding cone 602 into the packaging bag, and then the lifting cylinder 606 retracts to realize the delivery of the solid material.

[0197] S400: The multi-station rotating mechanism 300 moves for the third time, and moves the packaging bag with solid materials added thereto to the semi-solid material filling mechanism 700 for adding the semi-solid materials.

[0198] Specifically:

[0199] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0200] When the semi-solid material is put in, the protection mechanism 1300 is kept in a retracted state by the drive of the fourth driving cylinder 1301, and then the spiral shaft inside the semi-solid material filling mechanism 700 rotates, driving the semi-solid material inside to flow downward and fall into the packaging bag 1400 under the action of gravity until the time T 2 The rear spiral shaft stops rotating, i.e. stops dropping the material, and the delivery of the semi-solid material is completed. After the delivery is completed, the protection mechanism 1300 is driven by the fourth driving cylinder 1301 to maintain the extended state.

[0201] S500: The multi-station rotating mechanism 300 moves for the fourth time, and moves the packaging bag with the semi-solid material added thereto to the liquid material filling mechanism 800 for adding the liquid material.

[0202] Specifically:

[0203] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0204] When the liquid material is put in, the protection mechanism 1300 is kept in the retracted state by the drive of the fourth driving cylinder 1301, and then the liquid pump inside the liquid material filling mechanism 800 is started, driving the liquid material to flow in the hose until it falls into the packaging bag from the end of the hose. T 3 The liquid pump then stops running, i.e. stops dropping the material, and the delivery of the liquid material is completed. After the delivery is completed, the protection mechanism 1300 is driven by the fourth driving cylinder 1301 to maintain the extended state.

[0205] S600: The multi-station rotating mechanism 300 moves for the fifth time, and moves the packaging bag into which the liquid material has been added to the heat sealing mechanism 900 for heat-pressing sealing.

[0206] Specifically:

[0207] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0208] The controller controls the first rotating head 908 to rotate forward, and drives the first sliding rod 903 to move in the opposite direction through the gear rack transmission, so that the hot pressing head 904 approaches and contacts the bag opening of the packaging bag 1400 and squeezes them together. At this time, the hot steam flowing inside the hot pressing head 904 heats the bag opening of the packaging bag, causing them to fuse and adhere together to achieve hot pressing sealing. After completion, the controller controls the first rotating head 908 to reverse, so that the hot pressing head 904 is separated from the packaging bag 1400.

[0209] S700: The multi-station rotating mechanism 300 moves for the sixth time, and moves the heat-sealed packaging bag to the cold-sealing mechanism 1000 for cold-pressing sealing.

[0210] Specifically:

[0211] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0212] The movement mode of the cold sealing mechanism can refer to step S600, the only difference is that the hot pressing head 904 is replaced by an arc-shaped cold pressing head.

[0213] S800: The multi-station rotating mechanism 300 moves for the seventh time. After the cold-sealed packaging bag is moved to the discharging conveying mechanism 1100, the multi-station rotating mechanism 300 releases the bag opening, and the bag naturally falls to the discharging conveying mechanism 1100 and is conveyed out.

[0214] Specifically:

[0215] The movement mode of the multi-station rotating mechanism 300 can refer to step S200;

[0216] The pusher at the discharging station moves, and the push plate 308 is extended through the driving arm 307, thereby pushing the movable clamping block 3063 to rotate, so that the clamping assembly is in an open state (see the attached Figure 8 ), the packaging bag in the clamping assembly loses its clamping force and falls directly onto the discharge conveying mechanism 1100 under the action of gravity and can be transported out.
