Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and specifically to a high-speed spout bag packaging machine. Background Technology

[0002] With the rapid development of industries such as food, daily chemicals, and pharmaceuticals, spout bags are widely used for packaging materials such as granules, liquids, pastes, and powders due to their advantages such as easy pouring, good sealing, and convenient use. The corresponding spout bag packaging process typically includes core steps such as material filling, lid assembly, and sealing. The degree of automation, operational stability, and processing efficiency of packaging equipment directly affect the company's production efficiency and product packaging quality. Currently, existing spout bag packaging equipment has many shortcomings: On the one hand, most equipment adopts a linear conveying structure, with a fixed conveying path and a large space occupation. At the same time, the layout of each process device is scattered, resulting in a long transfer distance between processes. This not only reduces packaging efficiency but also easily leads to problems such as spout bag positioning deviation and material spillage during transfer. On the other hand, the conveying mechanism of existing equipment is mostly belt conveyor or chain conveyor, lacking a dedicated positioning station for spout bags. This causes spout bags to easily shift or tip over during transport, which in turn affects the accuracy of subsequent cap sorting and tightening, resulting in problems such as insecure cap assembly and poor sealing performance. In addition, the coordination between the functional modules of existing packaging equipment is poor, which affects the stability of equipment operation and makes it difficult to meet the needs of large-scale and high-speed production.

[0003] Therefore, developing a high-speed spout bag packaging machine that is compact, highly automated, stable in operation, and highly efficient in packaging has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Compared to traditional linear conveyor structures, this significantly shortens the conveying path, making the equipment more compact and effectively saving production space. Simultaneously, the circular rotary conveyor enables continuous and uninterrupted transport of spout bags.

The walking station ensures the positioning accuracy of the spout bags during each processing step. For example, during the weighing and feeding process, precise positioning prevents material spillage and improves weighing accuracy; during cap sorting and screwing, it ensures precise alignment between the cap and the spout, guarantees uniform screwing torque, and improves the robustness of the cap assembly; during the electromagnetic sealing process, precise positioning ensures accurate sealing position, improves sealing performance, and thus improves the consistency and pass rate of product packaging.

[0017] III. Simplify equipment structure and improve operational stability: The tracked circular rotary conveyor provides power to the plate chain conveyor through a cyclic drive mechanism. Each subsequent processing device can rely on this conveyor to achieve synchronous coordination with the conveying action, which significantly improves the operational stability of the equipment, meets the needs of large-scale and high-speed production, and effectively improves the production efficiency of enterprises.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example 1:

[0022] This invention provides a high-speed spout bag packaging machine, referenced Figures 1 to 36 As shown, the high-speed spout bag packaging machine includes a machine body 1, on which a chain-track type circular rotary conveyor 2, a feeding device 3, a cap sorting device 4, a cap screwing device 5, and an electromagnetic sealing device 6 are installed.

[0023] The tracked circular rotary conveyor 2 includes a circulating drive mechanism 23 and a plate chain conveyor mechanism 21. The plate chain conveyor mechanism 21 is connected to the circulating drive mechanism 23, and a walking station for conveying the spout bag is provided on the plate chain conveyor mechanism 21.

[0024] The feeding device 3, the capping device 5, and the electromagnetic sealing device 6 are arranged sequentially along the conveying direction of the plate chain conveyor 21, and the cap sorting device 4 is set at the position corresponding to the capping device 5.

[0025] During operation, a spout bag is fixed on the walking station. The circulating drive mechanism 23 drives the plate chain conveyor mechanism 21 to move, thereby conveying the spout bag to the feeding device 3, the capping device 5 (cap sorting device 4), and the electromagnetic sealing device 6 in sequence. The feeding device 3 places the material to be packaged into the spout bag. After sorting the spout caps, the cap sorting device 4 conveys the spout caps to the capping device 5. The capping device 5 tightens the spout caps onto the opening of the spout bag. Then, the electromagnetic sealing device 6 seals the bag opening and the spout caps.

[0026] In the above process, the present invention uses a tracked circular rotary conveyor to drive the walking station to move in a cycle. This not only stabilizes the conveying of spout bags and improves conveying efficiency, but also enables precise positioning to ensure conveying effect. At the same time, the cyclic conveying method can effectively improve space utilization.

[0027] The chain-track circular rotary conveyor 2, feeding device 3, cap sorting device 4, cap screwing device 5, and electromagnetic sealing device 6 work together to form an automated circular packaging production line for spout bags, which can effectively improve the coordination of each process and the processing accuracy. Example 2:

[0028] Example 2 is based on Example 1: like Figures 3 to 11 As shown, the tracked circular rotary conveyor 2 includes a ring guide mechanism 22, and a plate chain conveyor 21 is movably arranged around the outside of the ring guide mechanism 22.

[0029] The plate chain conveying mechanism 21 includes multiple mounting plate chain links 211 evenly distributed along the circumference. Each mounting plate chain link 211 is provided with the traveling station. Adjacent mounting plate chain links 211 are connected by chain group connecting links 212. The mounting plate chain links 211 and the chain group connecting links 212 are rotatably connected and form a ring.

[0030] Specifically, the chain link 212 includes two horizontally arranged connecting rods 2121, which are arranged in a hierarchical manner. The two ends of the connecting rods 2121 are respectively hinged to two adjacent mounting plate links 211.

[0031] This design offers several advantages. First, it allows the plate chain conveyor mechanism 21 to flexibly adapt to the turning requirements of the circular track, especially ensuring a smooth transition in the curved sections of the circular track, preventing jamming or concentrated stress during transport and improving the smoothness of the conveying process. Second, the modular splicing design facilitates the disassembly, replacement, and maintenance of individual mounting plate chain links 211. When a mounting plate chain link 211 or the fixing mechanism 24 malfunctions, only targeted repairs are required, reducing maintenance costs. Third, the number of mounting plate chain links 211 can be flexibly increased or decreased according to production needs, further enhancing the flexibility of equipment capacity expansion and process adjustment, and adapting to different batch production requirements.

[0032] A conveying roller 2112 is rotatably mounted on the mounting plate chain link 211. The conveying roller 2112 is a rolling wheel. A first track groove 223 is provided on the outer side of the ring gauge guide mechanism 22. The conveying roller 2112 and the first track groove 223 are in rolling cooperation.

[0033] The conveying rolling element 2112 and the first track groove 223 cooperate with each other. On the one hand, rolling friction is adopted, which has low frictional resistance and can effectively reduce component wear and extend component service life. On the other hand, the mounting plate chain link 211 moves along a fixed track, and the movement process is smooth and reliable.

[0034] To further improve the installation stability of the mounting plate chain link 211, each mounting plate chain link 211 is equipped with two conveying rollers 2112.

[0035] As an optional implementation, the cyclic drive mechanism 23 includes a cyclic power component 231 and a ring gauge drive wheel 232.

[0036] The circulating power assembly 231 uses an electric power unit, including a motor and a reducer. Its output end is connected to the ring gauge drive wheel 232 and can drive the ring gauge drive wheel 232 to rotate. A second track groove 2322 is provided circumferentially on the wheel wall of the ring drive wheel 232. The conveying rolling element 2112 rolls in cooperation with the second track groove 2322. The second track groove 2322 is tangent to and connected with the first track groove 223. The first track groove 223 and the second track groove 2322 form an annular track groove. The annular track groove provides stable guidance for the conveying rolling element 2112 throughout its entire journey, ensuring the continuity and stability of the cyclic motion.

[0037] The ring drive wheel 232 has multiple transmission grooves 2321 evenly spaced along the circumference on its wheel wall. The mounting plate chain link 211 is provided with a transmission shaft 2111 that is compatible with the transmission grooves 2321. The transmission shaft 2111 can mesh with the transmission grooves 2321. The meshing transmission structure ensures stable and reliable transmission and can effectively transmit the output power of the circulating power component 231 to the plate chain conveyor mechanism 21.

[0038] The ring gauge drive wheel 232 has two layers of transmission grooves 2321 arranged vertically on its wheel wall; the mounting plate chain link 211 has an upper transmission shaft and a lower transmission shaft arranged opposite each other vertically, the upper transmission shaft and the lower transmission shaft corresponding to the upper and lower layers of transmission grooves 2321 respectively.

[0039] The double-layer meshing transmission structure serves several purposes. First, it ensures more even force distribution between the ring gauge drive wheel 232 and the mounting plate chain link 211, avoiding localized force concentration caused by single-layer transmission. This reduces wear on the drive shaft 2111 and the transmission groove 2321, extending the service life of the transmission components. Second, the double-layer limiting fit further enhances the connection stability between the mounting plate chain link 211 and the ring gauge drive wheel 232, preventing risks such as tilting or detachment of the mounting plate chain link 211 during transport. This is especially beneficial in high-speed transport scenarios, effectively ensuring equipment safety. Third, it enhances the redundancy of power transmission. Even if a minor fault occurs in one layer of the transmission components, the other layer can temporarily maintain basic transmission functionality, reducing the impact of sudden shutdowns on production and improving the equipment's fault tolerance.

[0040] As an optional implementation, the walking station includes multiple fixed mechanisms 24.

[0041] Thus, a single mounting plate link 211 can transport multiple spout bags simultaneously.

[0042] Preferably, two fixing mechanisms 24 are provided on a mounting plate link 211.

[0043] As an optional implementation, the fixing mechanism 24 includes a fixing base 241 and a spout clamp 242.

[0044] The fixing base 241 is fixedly mounted on the mounting plate link 211. The fixing base 241 is provided with a mounting groove. The spout clamp 242 includes a movable clamping claw and a fixed clamping claw arranged opposite to each other. The movable clamping claw and the fixed clamping claw are inserted into the mounting groove. The middle position of the movable clamping claw is movably connected to the fixing base 241 through a cylindrical pin. The fixed clamping claw is fixedly connected to the fixing base 241 through two fixing pins. The movable clamping claw and the fixed clamping claw cooperate with each other to clamp the spout of the spout bag. When clamping the spout of the spout bag, the movable clamping claw can rotate at a small angle to adapt, making the spout bag assembly and disassembly more convenient without affecting the clamping stability.

[0045] As an optional implementation, the ring gauge guide mechanism 22 includes a linear guide rail 221 and a semicircular guide rail 222. The number of linear guide rails 221 is set to two, and the two linear guide rails 221 are arranged in parallel. The number of semicircular guide rails 222 is set to one, and the two ends of the opening of the semicircular guide rail 222 are respectively connected to the first ends of the two linear guide rails 221, and the second end of the linear guide rail 221 is tangent to the ring gauge drive wheel 232. In this way, a ring-shaped guide rail mechanism is formed to ensure the cyclic conveying effect.

[0046] As an optional implementation, the ring gauge guide mechanism includes a tensioning component 224, which is disposed between the linear guide rail 221 and the semi-circular guide rail 222.

[0047] The tensioning component 224 achieves tensioning of the plate chain conveyor mechanism 21 through the tensioning linear guide 221 and the semi-circular guide 222.

[0048] As an optional implementation, the tensioning assembly 224 includes a first mounting base 2241, a second mounting base 2242, a tensioning bolt 2243, a tensioning nut 2244, and a tensioning elastic element 2245. The first mounting base 2241 is disposed on the inner wall surface of the linear guide rail 221; the second mounting base 2242 is disposed on the inner wall surface of the semi-circular guide rail 222; the tensioning nut 2244 is fixedly disposed on the first mounting base 2241; the tensioning bolt 2243 passes through the tensioning nut 2244 and is threadedly connected to the second mounting base 2242, and the tensioning bolt 2243 and the tensioning nut 2244 are threadedly engaged; the tensioning elastic element 2245 is a flat wire spring, which is sleeved on the tensioning bolt 2243, and its two ends abut against the first mounting base 2241 and the second mounting base 2242 respectively.

[0049] This design offers several advantages. First, the threaded engagement of the tensioning bolt 2243 and the tensioning nut 2244 allows for precise fine-tuning of the tension, enabling accurate control of the track tension according to actual needs and ensuring optimal operating conditions. Second, the tensioning elastic element 2245 forms a buffer compensation structure, absorbing vibrations during equipment operation, reducing impact damage to the guide rail connection points, and automatically compensating for gaps during temperature changes or minor wear, maintaining track tension stability and avoiding frequent manual adjustments. Third, the first mounting base 2241 and the second mounting base 2242 are fixedly connected to the linear guide rail 221 and the semi-circular guide rail 222, respectively, ensuring a robust connection structure and stable installation of the tensioning assembly 224. Furthermore, the modular design facilitates the disassembly, replacement, and maintenance of the tensioning assembly 224, improving the ease of equipment maintenance.

[0050] As an optional implementation method, such as Figures 12 to 21 As shown, the feeding device 3 includes a weighing mechanism 32 and a cam-type rotary lifting feeding mechanism 31.

[0051] The cam-type rotary lifting and unloading mechanism 31 includes a lifting cam 311 and a lifting and unloading hopper 312. The lifting cam 311 is located above the ring gauge drive wheel 232. The top of the lifting cam 311 is provided with an annular cam rail surface. The lifting and unloading hopper 312 is movably arranged in the vertical direction. The lifting and unloading hopper 312 rotates synchronously with the ring gauge drive wheel 232. The lifting and unloading hopper 312 is connected to a moving part, which can move along the annular cam rail surface to drive the lifting and unloading hopper 312 to lift and lower.

[0052] During operation, the circulating power component 231 is activated, and the lifting hopper 312 rotates synchronously. The moving part moves along the annular cam rail surface at the top of the lifting cam 311. As the relative position of the moving part on the annular cam rail surface changes, the moving part rises and falls, thereby realizing the lifting and lowering of the lifting hopper 312.

[0053] The lifting cam 311 and the lifting hopper 312 with a movable part cooperate to form a cam mechanism, which can effectively convert the rotational motion of the output end of the circulating power component 231 into the lifting motion of the lifting hopper 312. This not only makes the lifting motion of the lifting hopper 312 mechanically linked with the conveying rhythm of the spout bag, ensuring precise synchronization and stability of continuous production, but also ensures a smooth lifting process, guaranteeing the service life of the components, while greatly improving efficiency and making it suitable for high-speed production.

[0054] The weighing mechanism 32 is located above the cam-type rotary lifting and unloading mechanism 31 and is used to weigh the materials to be packaged. The lifting and unloading hopper 312 below the weighing mechanism 32 is connected to the bottom discharge port of the weighing mechanism 32.

[0055] As an optional implementation, the annular cam track surface includes a feeding section 3111, a first transition section 3112, a waiting section 3113, and a second transition section 3114 connected end to end in the circumferential direction, and the height of the feeding section 3111 is less than the height of the waiting section 3113.

[0056] This configuration achieves a closed-loop cycle of "waiting for material - smooth transition - discharging - smooth reset" for the lifting hopper 312. The higher height of the waiting section 3113 provides ample space for the precise delivery of the spout bags, preventing interference between the lifting hopper 312 and the spout bags that are not yet in place; the lower height of the discharging section 3111 ensures that the material can be accurately injected into the bag opening, reducing spillage; the first transition section 3112 and the second transition section 3114 achieve a smooth connection between the high and low positions, avoiding sudden stops or jerks in the lifting action, further improving the stability of the discharging process, while reducing mechanical wear and adapting to long-term continuous production.

[0057] As an optional implementation, a lifting seat 313 is connected to the side wall of the lifting hopper 312. The moving component is a roller, which is rotatably mounted on the lifting seat 313 and rolls in contact with the annular cam track surface.

[0058] The roller and the annular cam track surface form rolling friction, which not only reduces frictional resistance and effectively reduces the driving load of the circulating power component 231, achieving energy saving and consumption reduction, but also makes the lifting response of the lifting hopper 312 more sensitive due to the rotation characteristics of the roller. Combined with the trajectory design of the annular cam track surface, it further improves the accuracy and stability of the lifting action and reduces the probability of jamming failure.

[0059] As an optional implementation, the cam-type circulating lifting and unloading device includes a buffer mechanism 316, which includes a buffer elastic element 3161. The buffer elastic element 3161 is connected and disposed between the ring gauge drive wheel 232 and the lifting seat 313.

[0060] The number of buffer elastic elements 3161 is set to multiple, and all the elastic elements are evenly arranged in the circumferential direction. The buffer elastic elements 3161 are tension springs, and their two ends are respectively connected to the ring gauge drive wheel 232 and the corresponding lifting seat 313.

[0061] The buffer mechanism 316 serves two purposes: firstly, it buffers the lifting and lowering motion; secondly, it has a pre-tightening function to ensure that the rolling elements are always in close contact with the annular cam rail surface, preventing disengagement due to vibration or high-speed operation and ensuring motion synchronization.

[0062] As an optional implementation, the cam-type rotary lifting and unloading mechanism 31 includes an unloading guide mechanism 317, which includes a guide post 3171 and a sliding sleeve 3172. The guide post 3171 is fixedly mounted on the top surface of the ring gauge drive wheel 232; the sliding sleeve 3172 is slidably mounted on the guide post 3171 and is fixedly mounted on the lifting seat 313.

[0063] The guide column 3171 and the sliding sleeve 3172 work together to effectively constrain the lifting and lowering movement of the lifting hopper 312, so that it can only move up and down in the vertical direction, avoiding tilting or deviation during the lifting and lowering process, and ensuring that the lifting hopper 312 can be accurately aligned with the spout bag mouth.

[0064] As an optional implementation, the cam-type rotary lifting and unloading mechanism 31 includes a support mechanism 318, which is fixedly mounted on the top of the guide column 3171. A guide groove 3184 is provided on the support mechanism 318 in the vertical direction. One end of the lifting seat 313 is connected to the outer wall of the lifting and unloading hopper 312, and the other end passes through the guide groove 3184 and is connected to the rolling element. The lifting seat 313 and the guide groove 3184 are adapted to each other and slide together in the vertical direction.

[0065] The guide groove 3184 further limits the vertical movement accuracy of the lifting hopper 312. Especially under the drive of the high-speed rotating ring gauge drive wheel 232, it can effectively resist the influence of centrifugal force on the hopper posture and avoid swaying or deviation.

[0066] As an optional implementation, the support mechanism 318 includes a lower mounting plate 3181, an upper mounting plate 3182, and an outer cover 3183. The lower mounting plate 3181 is fixedly mounted on the top of the guide column 3171; the upper mounting plate 3182 is located above the lower mounting plate 3181; the outer cover 3183 covers the outer side of the upper mounting plate 3182 and the lower mounting plate 3181, and the guide groove 3184 is arranged vertically on the outer cover 3183; the lifting hopper 312 is located outside the outer cover 3183, and the lifting cam 311 is located inside the outer cover 3183.

[0067] The lower mounting plate 3181, the upper mounting plate 3182, and the outer protective cover 3183 form a closed protective structure, which encapsulates the core transmission components such as the lifting cam 311 and the rolling parts inside the outer protective cover 3183, while the lifting hopper 312 is located on the outside, thus achieving physical isolation between the transmission mechanism and the material filling area.

[0068] The outer protective cover 3183 can effectively block dust and debris from entering the transmission components in the production environment, avoiding accelerated wear or movement jamming, while preventing debris generated during transmission from contaminating the materials and ensuring packaging cleanliness.

[0069] As an optional implementation, the cam-type rotary lifting and unloading mechanism 31 includes a buffer hopper 314, which is located above the lifting and unloading hopper 312.

[0070] The buffer hopper 314 serves to buffer materials and stabilize pressure. The buffer hopper 314 can pre-store a certain amount of material to avoid interruption of feeding or unstable flow caused by fluctuations in upstream material supply, thus ensuring the continuity of filling. At the same time, the material in the buffer hopper 314 forms a certain level pressure, which enables the material to maintain a stable flow rate during the feeding process, avoiding problems such as flow interruption and material slugging, and improving the uniformity of filling volume.

[0071] As an optional implementation, the cam-type rotary lifting unloading mechanism 31 includes a flow control port 315, which includes an unloading port body 3151 and a flow control plate 3152.

[0072] The discharge port body 3151 is fixedly installed at the bottom of the buffer hopper 314. The discharge port body 3151 is inserted into the lifting discharge hopper 312, which can shorten the material falling path and reduce dust and spillage.

[0073] The flow control plate 3152 is slidably inserted into the discharge port body 3151 and can control the flow area of ​​the discharge port body 3151. In actual application, the flow area can be adjusted by adjusting the depth of the flow control plate 3152 inserted into the discharge port body 3151, thus adapting to different materials and particles of different diameters, and has a wide range of applications.

[0074] The flow control plate 3152 is tilted, which not only ensures the flow control effect but also has a guiding function, effectively guiding the material to move downward and ensuring the feeding effect.

[0075] As an optional implementation, the number of lifting hoppers 312 and buffer hoppers 314 is the same, and multiple lifting hoppers 312 and buffer hoppers 314 are provided. All lifting hoppers 312 are arranged at intervals around the lifting cam 311.

[0076] This setup enables multi-station cyclic feeding, significantly improving feeding efficiency per unit time and adapting to the capacity requirements of high-speed spout bag packaging production lines.

[0077] As an optional implementation, the lid sorting device 4 includes a lid sorting frame 41, a material box 42, a plate chain lid sorting mechanism 43, an air blowing feeding mechanism 44, a lid sorting channel 45, and a lid mounting mechanism 46.

[0078] The material box 42 is set on the lid sorting machine frame 41 and is used to hold the spout lids.

[0079] The plate chain lid sorting mechanism 43 is installed inside the lid sorting frame 41. The plate chain lid sorting mechanism 43 includes a plate chain that moves in the circumferential direction. Multiple spout partitions 431 are arranged on the plate chain along its circulating conveying direction. The space between two adjacent spout partitions 431 is adapted to the diameter of the spout lid. This space forms a positioning groove 432 for positioning the spout lid. Each positioning groove 432 can position multiple spout lids in a row in the horizontal direction.

[0080] The air blowing and feeding mechanism 44 includes multiple air nozzles, which are installed inside the cap sorting frame 41. The air outlets face the inlet end of the cap sorting channel 45. When the positioning groove 432, which is positioned with a spout cap, moves to the air blowing and feeding mechanism 44, the gas blown out by the air nozzles pushes the cap from the inlet end into the cap sorting channel 45.

[0081] The outlet end of the lid channel 45 is connected to the upper cover mechanism 46, and the width of the lid channel 45 is adapted to the diameter of the spout cover.

[0082] The plate chain cap sorting mechanism 43, the air blowing feeding mechanism 44, and the cap sorting channel 45 work together to effectively sort the messy bottle caps in the material box 42 and transport them to the capping mechanism 46 in an orderly and stable manner.

[0083] The cover mechanism 46 includes a cover pushing component 461 and a cover support 462. The cover pushing component 461 is a cylinder, and its telescopic end is connected to the cover support 462. The cover support 462 is located below the outlet end.

[0084] During the capping process, the bottle cap output from the outlet end of the cap channel 45 falls onto the cap holder 462. The cap pushing component 461 pushes the cap holder 462 to move in a straight line, thereby pushing the spout cap on the cap holder 462 to below the cap screwing device 5, resulting in a significant cap pushing effect.

[0085] As an optional implementation, the cap screwing device 5 includes a cap screwing lifting assembly 51 and a cap screwing execution assembly 52. ​​The cap screwing lifting assembly 51 is connected to the cap screwing execution assembly 52 and can drive the cap screwing execution assembly 52 to rise and fall.

[0086] Preferably, the cap-tightening device 5 includes a support frame, and the cap-tightening lifting assembly 51 is an electric lifting assembly, including a lead screw and a lifting frame with a threaded hole. The lifting frame is threadedly connected to the lead screw through the threaded hole. The support frame is provided with a guide rod, which passes through the lifting frame and slides with the lifting frame.

[0087] The cap screwing execution assembly 52 includes a cap screwing power assembly 521 and a spout cap clamping assembly 522. The output end of the cap screwing power assembly 521 is connected to the spout cap clamping assembly 522 and can drive the spout cap clamping assembly 522 to rotate. The spout cap clamping assembly 522 is used to clamp the spout cap supplied by the cap feeding device 4.

[0088] When tightening the cap, the cap tightening lifting component 51 drives the cap tightening execution component 52 to move down until the cap is located inside the spout cap clamping component 522. Then the cap tightening power component 521 drives the spout cap clamping component 522 to rotate, thereby tightening the cap.

[0089] To further improve the capping effect, a spout locking mechanism is also provided below the cap holder 462. The spout locking mechanism includes a locking telescopic component and a spout fixing clip. The spout telescopic component is connected to the spout fixing clip and can drive the spout fixing clip to move, thereby fixing the spout bag on the corresponding walking station. As an optional implementation, the electromagnetic sealing device 6 includes a sealing lifting assembly 61 and an electromagnetic sealing machine 62.

[0090] The sealing lifting assembly 61 uses a vertically arranged cylinder, whose telescopic end is connected to the electromagnetic sealing machine 62 and can drive the electromagnetic sealing machine 62 to lift and lower. The electromagnetic sealing machine 62 is used to seal the spout and spout cap.

[0091] The electromagnetic sealing machine 62 is used for sealing, which features fast sealing speed, good sealing performance and uniform heating. It can complete the sealing of the spout and the lid in a short time, which is suitable for the pace of high-speed packaging production lines.

[0092] As an optional implementation, the high-speed spout bag packaging machine further includes a bag-vibrating device 7, which is located downstream of the feeding device 3 and upstream of the cap-sorting device 4.

[0093] The bag-vibrating device 7 includes a bag-vibrating lifting assembly 71 and a bag-patting extension plate 72, with the bag-vibrating lifting assembly 71 connected to the bag-patting extension plate 72.

[0094] After the material is unloaded, the plate chain conveyor moves the spout bag to the bag vibrating device 7. The bag vibrating lifting component 71 drives the bag-tapping extension plate 72 to rise and fall, thereby repeatedly tapping the bottom of the corresponding spout bag. This makes the material inside the bag evenly spread out, avoiding the material from concentrating at the spout, which would prevent the cap from accurately aligning with the spout during subsequent cap sorting and tightening. At the same time, it ensures that the bag body is regular in shape and improves the product's appearance quality.

[0095] The bag-tapping extension plate 72 is designed in a two-wing shape, which can simultaneously tap and vibrate multiple spout bags, making it suitable for high-speed conveying.

[0096] The bag-vibrating device 7 also includes a height adjustment component 73 for adjusting the height of the bag-vibrating lifting assembly 71 and the bag-patting extension plate 72. The height adjustment component 73 adopts a screw and nut assembly, and when adjusting the height, the screw is rotated by a handwheel.

[0097] As an optional implementation, the high-speed spout bag packaging machine includes an air blowing device 8 located upstream of the feeding device 3. The device blows air onto the spout bag before feeding, which on the one hand supports the spout bag to facilitate subsequent feeding, and on the other hand has a cleaning function, blowing out dust, impurities, etc.

[0098] The high-speed spout bag packaging machine includes a nitrogen blowing device 9 located between the cap feeding device 4 and the bag shaking device 7. Nitrogen is blown into the spout bag before the cap is screwed on, which can expel the air inside the bag and use inert gas to isolate the air, thereby extending the product's shelf life.

[0099] As an optional implementation, the high-speed spout bag packaging machine includes a bag body coding device 10 disposed between the bag shaking device 7 and the nitrogen blowing device 9; the bag body coding device 10 includes a coding panel and a coding back plate disposed opposite to each other, a laser printhead is disposed on the coding panel, and the inlet ends of the coding panel and the coding back plate are configured as an angle structure. When the spout bag passes through the bag body coding device 10, the bag body coding device 10 prints information such as production date, shelf life, and batch number on the body of the spout bag.

[0100] The high-speed spout bag packaging machine includes a cap coding device 11 located downstream of the electromagnetic sealing device 6. The cap coding device 11 can print product codes, anti-counterfeiting labels and other information on the surface of the sealed spout cap, realizing dual information marking of "bag body-cap". This makes it convenient for consumers to view product information and also facilitates production traceability and quality control for enterprises. It is especially suitable for large-scale, multi-batch production scenarios.

[0101] As an optional implementation, the high-speed spout bag packaging machine includes a bag-removing device 12, which includes a bag-removing telescopic assembly 121 and a top bag assembly 122 connected to the bag-removing telescopic assembly 121. The bag-removing telescopic assembly 121 is a cylinder, and the top bag assembly 122 includes a top plate connected to the telescopic end of the cylinder and a top block disposed on the top plate.

[0102] When the bag-removing telescopic component 121 can drive the top bag component 122 to extend, the top block pushes the spout bag away from the corresponding fixing mechanism 24, thus completing the unloading of the spout bag.
