Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically a circular track food processing line. Background Technology

[0002] In the food processing and packaging industry, automated bagging equipment is widely used in the packaging of various materials. With increasing demands for production efficiency, companies are placing higher requirements on the stability, bagging accuracy, and coordination of equipment during high-speed operation. Traditional bagging equipment often employs linear conveying and intermittent bagging methods, resulting in problems such as disjointed process connections, large footprint, and limited bagging efficiency. Especially during the transfer of materials from the conveyor line to the packaging bag, factors such as mismatched action timing, unstable material posture changes, insufficient bag opening, or inaccurate dynamic alignment often lead to material jamming, bagging failures, or substandard packaging quality, affecting overall production line efficiency and product qualification rate.

[0003] In recent years, bagging systems combining circular conveyor lines with multi-station rotary receiving mechanisms have gradually attracted attention. This type of equipment achieves continuous material feeding through circular conveying, and works in conjunction with the rotary bag receiving mechanism to complete processes such as bag opening, filling, and unloading. It boasts advantages such as compact structure, small footprint, and high operating efficiency. However, existing circular bagging equipment still faces the following technical challenges in practical applications: First, each execution unit (such as pushing, flipping, bag opening, and material handling) often uses an independent power source, making it difficult to achieve high-precision linkage in the action sequence, easily leading to action delays or interference; second, when the material transitions from a horizontal conveying state to a vertical bagging state, the attitude conversion mechanism is complex, and the coordination between flipping and material handling actions is insufficient, affecting bagging stability; third, the bag opening mechanism has poor adaptability to bag openings, making it difficult to accommodate various bag types or opening sizes, and lacks dynamic tracking functionality during the bagging process, easily leading to misalignment between the material and the bag opening.

[0004] Therefore, it is necessary to provide a compact, coordinated, and highly accurate circular track food processing line to solve the problems existing in the prior art. Summary of the Invention

[0005] The technical problem to be solved by this application is to overcome the existing defects and provide a circular track food processing line that can effectively solve the problems in the background art.

The flipping connecting bracket is connected to the flipping intermediate connecting rod. The end of the flipping intermediate connecting rod is connected to the flipping side bracket. The rotating gear shaft is rotatably connected inside the flipping side bracket.

[0016] As a preferred technical solution of this application, the bag support assembly includes a chute plate and a flared part. The chute plate is located on the lower surface of the connecting frame in the end connector. A sliding guide groove is provided on the chute plate, and a flared part is provided in the sliding guide groove.

The transverse pusher plate is connected to the pusher connecting seat.

[0018] As a preferred technical solution of this application, the annular conveyor line includes a support frame, an arc-shaped slide rail, a guide chute, a material box, a gear transmission assembly, and a sprocket assembly. The support frame is provided with an arc-shaped slide rail, and the arc-shaped slide rail and the guide chute are correspondingly arranged. The material box is disposed on the arc-shaped slide rail and the guide chute. The sprocket assembly is disposed between the arc-shaped slide rail and the guide chute. The gear transmission assembly is located on the lower surface of the support frame and transmits power to the sprocket assembly, thereby driving the material box to move on the guide member formed by the arc-shaped slide rail and the guide chute.

[0019] As a preferred technical solution of this application, the receiving mechanism includes a bag clamping component, a bag opening component, and a main rotating component. The main rotating component is the main mechanism, and a bag clamping component is provided on its outer circumference. The bag opening component is provided on the main rotating component and is used to open the bag held by the bag clamping component.

[0020] As a preferred technical solution of this application, the gear transmission assembly adopts a helical gear transmission group, wherein the first gear in the helical gear transmission group is coaxially arranged with the sprocket in the sprocket assembly.

[0021] Compared with existing technologies, the beneficial effects of this application are as follows: This application uses a power system as a single power source, employing a combination of cam transmission and linkage mechanisms to synchronously transmit power to execution units such as the circular conveyor line, horizontal pushing components, flipping components, material tracking group, bag supporting group, and vertical material ejection group. Through precise design of the phase angle of each cam, strict timing linkage between multiple actions such as material conveying, horizontal pushing, 90° flipping, dynamic tracking, bag opening, and vertical material ejection is achieved. Seamless connection between each process effectively avoids action delays, interference, or timing errors caused by using multiple independent power sources, significantly improving the coordination and stability of the entire line operation and ensuring the continuity and reliability of the bagging process.

[0022] By setting up a material transfer group and a vertical material ejection group, and using an ejection drive cam to simultaneously drive the flipping component and the ejection drive group, high-precision matching of the flipping and ejection actions is achieved. When the transfer box completes a 90° flip driven by the flipping component, changing the material's horizontal posture to a vertical posture, the ejection plate immediately presses down to eject the material vertically, making the entire process smooth and continuous. This structure avoids the problems of material stagnation, jamming, or unstable posture in the transfer box caused by asynchronous flipping and ejection actions, ensuring that the material falls accurately into the bag in a vertical posture, thus improving the bagging success rate.

[0023] The bag-supporting assembly incorporates an elastic flaring structure, utilizing springs to provide elastic pre-tension. This allows the guide rollers to adapt to different sized food bags during the bag-supporting process, ensuring uniform and stable bag opening and preventing bagging obstruction caused by incomplete opening. Simultaneously, a material tracking assembly drives the bag-supporting assembly to move synchronously along the material's descent direction during material tumbling, ensuring the opened bag opening always follows the material's falling position, achieving dynamic alignment during bagging. This effectively prevents material from colliding with the bag edge or falling out due to a fixed bag opening position, further improving bagging accuracy and reliability.

[0024] The circular conveyor line employs a drive system combining helical gear transmission and sprocket assembly. The helical gear transmission converts vertical rotational motion into horizontal rotation, offering advantages such as smooth meshing, high load-bearing capacity, and low noise. This effectively reduces vibration of the material container during high-speed operation, ensuring the positional stability of the material during conveying. Simultaneously, the dual-guide structure, formed by the arc-shaped slide rail and guide chute, ensures the material container maintains a stable posture during circular motion, providing a precise material positioning basis for subsequent pushing actions.

[0025] The circular conveyor line enables continuous material feeding, and in conjunction with the rotary multi-station receiving mechanism, the overall structure is compact and occupies a small area. The receiving mechanism, through its main rotating component, drives the bag clamping component through the bag loading, bag supporting, bag filling, and bag unloading stations in sequence, realizing continuous bagging operations. It works efficiently with the circular conveyor and feeding unit of the loading mechanism, significantly improving the overall production efficiency of the line and making it suitable for large-scale automated production scenarios.

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0046] Please see Figure 1-18This application provides a technical solution: a circular track food processing line, including a receiving mechanism 1 and a feeding mechanism 2. The feeding units 22 in the receiving mechanism 1 and the feeding mechanism 2 are spatially corresponding, so that the feeding mechanism 2 can accurately feed the material into the food bag held by the receiving mechanism 1.

[0047] The feeding mechanism 2, as the core feeding and loading unit of the entire processing line, mainly consists of three parts: the power system 21, the circular conveyor line 23, and the feeding unit 22.

[0048] The power system 21 serves as the power source for the entire feeding mechanism 2, and is connected to the circular conveyor line 23 and the feeding unit 22 respectively. Specifically, the power system 21 includes a drive motor, the output of which transmits power to the drive end of the circular conveyor line 23 and each cam mechanism in the feeding unit 22 via a drive shaft, gear set, or synchronous belt, thereby realizing the continuous operation of the circular conveyor line 23 and the sequential linkage of each moving part in the feeding unit 22.

[0049] The feeding unit 22, as a module that realizes the transformation of materials from conveying state to bagging state, integrates a horizontal pushing component 225, a material transfer group 224, a bag supporting group 223, a material tracking group 222, and a vertical material pushing group 221. Under the unified drive of the power system 21, the above components operate sequentially according to a preset timing sequence, jointly completing the processes of material pushing, flipping, bag opening, dynamic tracking, and material pushing and bagging.

[0050] The circular conveyor line 23 is arranged in a circular shape, and its structure includes a support frame 231, an arc-shaped slide rail 232, a guide chute 233, a material box 234, a gear transmission assembly 235, and a sprocket assembly 236.

[0051] The support frame 231 serves as the mounting base for the entire circular conveyor line 23, and its upper surface is fixedly equipped with an arc-shaped slide rail 232 and a guide groove 233. The arc-shaped slide rail 232 and the guide groove 233 are arranged parallel to each other and maintain a certain distance, together forming the sliding guide structure of the material container 234. The material container 234 is used to carry the material to be bagged. Its bottom is slidably mounted on the arc-shaped slide rail 232, while the side of the material container 234 cooperates with the guide groove 233, thereby ensuring that the material container 234 maintains a stable posture during movement.

[0052] The sprocket assembly 236 is disposed between the arc-shaped slide rail 232 and the guide groove 233, and is arranged along a circular path. The gear transmission assembly 235 is disposed on the lower surface of the support frame 231, with its input end connected to the output end of the power system 21 and its output end connected to the sprocket assembly 236. When the power system 21 drives the gear transmission assembly 235 to rotate, the gear transmission assembly 235 drives the sprocket assembly 236 to rotate in a circular direction, and the sprocket assembly 236 further drives the material box 234 to move along the circular track formed by the arc-shaped slide rail 232 and the guide groove 233.

[0053] In a preferred embodiment, the gear transmission assembly 235 employs a helical gear transmission group, in which the first gear is coaxially arranged with the sprocket in the sprocket assembly 236. This converts vertical rotational motion into horizontal rotation. Helical gear transmission offers advantages such as smooth meshing, high load-bearing capacity, and low noise, effectively improving the operational stability of the circular conveyor line 23, reducing vibration of the material container 234 during high-speed operation, and ensuring the positional stability of the material during conveying.

[0054] When the circular conveyor line 23 is in operation, the material carrier 234 carries the material and moves continuously along the circular track. When the material carrier 234 moves to the discharge end of the circular conveyor line 23, its position corresponds to the transverse pusher 225, preparing for the subsequent pushing action.

[0055] The transverse pusher 225 is located at the discharge end of the circular conveyor line 23. Its structure includes a pusher cam 2251, a pusher connecting frame 2252, a sliding guide rail 2253, a connecting groove plate 2254, a transverse pusher plate 2255, and a pusher connecting seat 2256.

[0056] The pusher cam 2251 is connected to the power system 21, and its outer contour has a cam curve with a specific trajectory. One end of the pusher connecting frame 2252 mates with the cam groove or cam surface of the pusher cam 2251, and the other end is fixedly connected to the connecting groove plate 2254. The sliding guide rail 2253 is fixedly set in the horizontal direction, and the connecting groove plate 2254 is slidably set on the sliding guide rail 2253. The pusher connecting seat 2256 is set at the front end of the connecting groove plate 2254, and the transverse pusher plate 2255 is fixedly installed on the pusher connecting seat 2256. The pushing direction of the transverse pusher plate 2255 is directly opposite to the material box 234 at the discharge end of the circular conveyor line 23.

[0057] When the power system 21 drives the pusher cam 2251 to rotate, the pusher cam 2251 drives the pusher connecting frame 2252 to reciprocate in the horizontal direction through the cam mechanism. The pusher connecting frame 2252 drives the connecting slot plate 2254 to slide linearly back and forth along the sliding guide rail 2253, and then drives the transverse pusher plate 2255 to move closer to or away from the material box 234 through the pusher connecting seat 2256.

[0058] During the pushing action phase, the horizontal pusher plate 2255 moves towards the material carrier 234, pushing the material in the material carrier 234 horizontally into the transfer material carrier 2242 of the material transfer group 224. After the pushing action is completed, the horizontal pusher plate 2255 returns to its original position under the drive of the pusher cam 2251, waiting for the next push.

[0059] The transverse pusher 225 is driven by a cam, which has the advantages of fast action speed, high position accuracy and smooth reciprocating motion. It can ensure the accurate transfer of materials from the circular conveyor line 23 to the material transfer group 224 and avoid the materials from shifting or falling during the transfer process.

[0060] The material transfer unit 224 is used to collect materials from the circular conveyor line 23 and complete the attitude change before the materials are transferred to the bagging position. The material transfer unit 224 mainly includes a flipping component 2241 and a transfer box 2242.

[0061] The transfer box 2242 has a trough-shaped structure, and its opening direction is opposite to the pushing direction of the transverse pusher 225 in the initial state, and is used to receive the material pushed out from the loading box 234. At this time, the material is in a horizontal position in the transfer box 2242.

[0062] The flipping component 2241 is driven to connect with the transfer box 2242, and is used to drive the transfer box 2242 to flip 90° around the horizontal axis.

[0063] Specifically, the flipping component 2241 includes a rotating gear shaft 22411, a flipping connecting bracket 22412, a flipping intermediate connecting rod 22413, and a flipping side bracket 22414.

[0064] One end of the flipping connecting bracket 22412 is connected to the guide groove on the other side of the material-push driving cam 22111, meaning the power for the flipping component 2241 comes from the material-push driving cam 22111. Driven by the power system 21, the material-push driving cam 22111 rotates, with one guide groove driving the material-push action and the other guide groove driving the flipping action, achieving a time-series linkage between material-push and flipping. The other end of the flipping connecting bracket 22412 is connected to the flipping intermediate connecting rod 22413, and the end of the flipping intermediate connecting rod 22413 is connected to the flipping side frame 22414. The rotating gear shaft 22411 is rotatably mounted within the flipping side frame 22414, and the intermediate material box 2242 is fixedly connected to the rotating gear shaft 22411.

[0065] When the material-pushing drive cam 22111 rotates, its other side guide groove drives the tilting side bracket 22414 to swing through the tilting connecting bracket 22412 and the tilting intermediate connecting rod 22413. The tilting side bracket 22414 further drives the rotating gear shaft 22411 to rotate, thereby driving the transfer box 2242 to complete a 90° tilt. After tilting, the material in the transfer box 2242 changes from a horizontal posture to a vertical posture, with its lower opening facing the already opened food bag opening, preparing for subsequent vertical material feeding.

[0066] The flipping mechanism adopts a combination of cam drive and linkage transmission, which is compact in structure and has a crisp and clean flipping action. It also shares the same power source with the material feeding action, ensuring precise timing matching between flipping and material feeding.

[0067] The specific structure of the sinking assembly includes a sinking cam component 22311, a sinking cam connector 22312, a lifting connecting rod 22313, and a nozzle support plate 22314.

[0068] The guide groove of the sinking cam component 22311 is connected to the sinking cam connector 22312, and the end of the sinking cam connector 22312 is connected to the lifting connecting rod 22313. The nozzle support plate 22314 is located on the top of the lifting connecting rod 22313. When the power system 21 drives the sinking cam component 22311 to rotate, its guide groove drives the lifting connecting rod 22313 to move up and down through the sinking cam connector 22312, thereby driving the nozzle support plate 22314 and the sliding guide wheel component 2232 installed on it to rise and fall synchronously.

[0069] When the bag-supporting action begins, the guide wheel 2232 of the chute sinks to the preset position under the action of the lifting drive unit. At this time, the material nozzle slides into the opening of the food bag held by the receiving mechanism 1, ensuring that the material can completely enter the food bag.

[0070] The bag-opening assembly 223 is used to open the food bag to be filled, so that the bag opening is large enough to receive the material. The bag-opening assembly 223 mainly includes a chute plate 2235 and a flaring component, wherein the chute guide wheel 2232 of the flaring component is located in the sliding guide groove of the chute plate 2235, and the bag-opening assembly 223 is correspondingly arranged with the material transfer assembly 224.

[0071] As a further improvement, the bag support assembly 223 also includes a flared member disposed within the sliding guide groove of the slide plate 2235. The flared member includes a slide guide wheel 2232, a spring 2233, and a guide wheel mounting base 2234. The slide guide wheel 2232 is mounted on the guide wheel mounting base 2234 and slidably disposed within the sliding guide groove on the slide plate 2235. The spring 2233 is disposed between the guide wheel mounting base 2234 and the material transfer assembly 224 to provide elastic preload.

[0072] During the bag-opening process, the sliding guide wheel 2232 moves outward along the sliding guide groove within the sliding plate 2235, at which point the food bag is opened. After resetting, the sliding guide wheel 2232 returns to its original position along the sliding guide groove under the action of the spring 2233. This elastic flaring structure can adapt to food bags of different sizes, ensuring the uniformity and stability of the bag opening and avoiding obstruction of material filling due to incomplete bag opening.

[0073] The material tracking group 222 is used to drive the bag support group 223 to move along the direction of material falling during the material flipping process, so that the bag opening and the material are dynamically aligned and the material can be accurately dropped into the bag.

[0074] The material tracking assembly 222 includes a drive component 2221, a connector 2222, and a guide component 2223. The drive component 2221 has a guide groove that is connected to the power system 21. The connector 2222 is disposed within the guide groove of the drive component 2221 and connects to the guide component 2223. A connecting support 24 is also provided on the outer side of the connector 2222, which connects to the material tracking assembly 222 and provides support for it.

[0075] The specific structure of connector 2222 includes a guide shaft 22221, a transfer swing arm 22222, a swing arm mounting bracket 22223, and a movable wheel 22224. The upper end of the guide shaft 22221 is rotatably mounted with the transfer swing arm 22222, and the movable wheel 22224 is connected to a slot at the end of the transfer swing arm 22222. The swing arm mounting bracket 22223 is slidably mounted on a sliding guide rail 22225 and can slide along the sliding guide rail 22225. The swing arm mounting bracket 22223 is also provided with an end connecting bracket 22226 for connecting other components.

[0076] The guide component 2223 includes a lateral mounting guide shaft 22231, a central guide rod 22232, and a lateral pull rod 22233. The lateral pull rod 22233 is connected to the swing arm placement frame 22223, and the central guide rod 22232 is positioned between the lateral pull rod 22233 and the material transfer assembly 224. The flipping component 2241 is coaxially arranged with the central guide rod 22232, ensuring that the movement of the material tracking assembly 222 and the movement of the flipping component 2241 are coordinated.

[0077] When the drive component 2221 rotates under the drive of the power system 21, its guide groove drives the transfer swing arm 22222 to swing through the movable wheel 22224. The transfer swing arm 22222 further drives the swing arm placement frame 22223 to slide along the sliding guide rail 22225. The movement of the swing arm placement frame 22223 is transmitted to the bag support assembly 223 through the end connecting frame 22226, thereby driving the bag support assembly 223 to rise and fall synchronously during the material flipping process.

[0078] Specifically, when the material transfer group 224 begins to flip, the material tracking group 222 moves simultaneously, driving the bag-supporting group 223 to move as well, ensuring that the opened bag opening always follows the falling position of the material. When the material is completely flipped to a vertical position, the bag-supporting group 223 also moves synchronously to a position aligned with the bottom of the material, ensuring that the material can enter the bag without obstruction. This dynamic tracking function effectively avoids the problem of material colliding with the edge of the bag opening or falling out due to the fixed position of the bag opening during the material's fall, thus improving the success rate of bagging.

[0079] The vertical material ejector assembly 221 is used to vertically eject the material from the material transfer assembly 224 and allow it to enter the food bag in the receiving mechanism 1. The vertical material ejector assembly 221 consists of an ejector drive assembly 2211 and a vertical material ejector frame 2212.

[0080] The material-pumping drive assembly 2211 includes a material-pumping drive cam 22111, a material-pumping connecting rod 22112, a material-pumping support frame 22113, and a material-pumping hinge frame 22114. The material-pumping connecting rod 22112 is disposed within the guide groove of the material-pumping drive cam 22111, and is connected to the material-pumping hinge frame 22114. The middle portion of the material-pumping hinge frame 22114 is hinged to the material-pumping support frame 22113, and the end of the material-pumping hinge frame 22114 is connected to the vertical material-pumping guide plate 22122 in the vertical material-pumping frame 2212 via a connector.

[0081] The vertical material feeding frame 2212 includes a guide frame 22121, a vertical material feeding guide plate 22122, and a feeding plate 22123. The guide frame 22121 is vertically arranged and has a linear slide rail mounted on it. The vertical material feeding guide plate 22122 is slidably disposed on the linear slide rail of the guide frame 22121, and the feeding plate 22123 is connected to the lower end of the vertical material feeding guide plate 22122. The feeding plate 22123 is positioned opposite to the top opening of the transfer box 2242.

[0082] When the material-pumping drive cam 22111 rotates under the drive of the power system 21, its guide slide groove drives the material-pumping hinge frame 22114 to swing around its hinge point with the material-pumping support frame 22113 via the material-pumping connecting rod 22112. The end of the material-pumping hinge frame 22114 drives the vertical material-pumping guide plate 22122 to slide downward along the linear slide rail of the guide frame 22121 via the connector, thereby driving the material-pumping plate 22123 to move vertically downward. The material-pumping plate 22123 passes downward through the top opening of the transfer box 2242, vertically pucking out the material inside. Under the combined action of gravity and the material-pumping force, the material falls into the opened food bag.

[0083] After the material-push action is completed, the material-push drive cam 22111 continues to rotate, driving the vertical material-push frame 2212 to reset upwards through the material-push connecting rod 22112 and the material-push hinge frame 22114, waiting for the next material-push command.

[0084] The vertical material-push assembly 221 is driven by a cam-linkage mechanism, which has the advantages of large material-push force, rapid action, and precise stroke. Since the material-push driving cam 22111 simultaneously drives the flipping component 2241 and the material-push driving assembly 2211, the flipping action and the material-push action are precisely coordinated in timing: after the intermediate material box 2242 completes a 90° flip, the material-push plate 22123 immediately presses down to push out the material. The whole process is smooth and continuous, avoiding material retention or jamming in the intermediate material box 2242.

[0085] The receiving mechanism 1 is used to clamp the food bag and open the bag opening before bagging. It is set in correspondence with the feeding unit 22 in the feeding mechanism 2 to receive the material pushed from the vertical feeding group 221.

[0086] The receiving mechanism 1 includes a bag clamping component 11, a bag opening component 12, and a main rotating component 13. The main rotating component 13 serves as the main structure of the receiving mechanism 1 and can rotate intermittently around its axis under power drive. Multiple bag clamping components 11 are evenly distributed circumferentially on the outer side of the main rotating component 13, each clamping component 11 being used to clamp one food bag. The bag opening component 12 is located on the main rotating component 13, corresponding to the position of the bag clamping component 11, and is used to open the opening of the food bag clamped by the bag clamping component 11.

[0087] In use: The main rotating component 13 drives the bag clamping component 11 to pass sequentially through the bag loading station, bag opening station, bag filling station, and bag unloading station. At the bag loading station, the bag clamping component 11 holds the edge of the food bag opening. When rotating to the bag opening station, the bag opening component 12 actuates, opening the bag opening to a predetermined size. Subsequently, the main rotating component 13 continues to rotate, sending the opened food bag to the bag filling station corresponding to the feeding unit 22 of the feeding mechanism 2. At this time, the sliding guide wheel component 2232 of the bag opening assembly 223 further inserts into the bag opening and assists in opening it, the material tracking assembly 222 drives the bag opening assembly 223 to dynamically follow, and the vertical material pushing assembly 221 pushes the material into the bag. After bagging is completed, the main rotating component 13 rotates the food bag containing the material to the bag unloading station, where it is removed by subsequent equipment or manually.

[0088] The receiving mechanism 1 adopts a rotary multi-station structure, which can realize continuous bagging operation. It works in high efficiency with the circular conveyor line 23 and feeding unit 22 of the feeding mechanism 2, which significantly improves the production efficiency of the whole line.

[0089] The power system 21 serves as the core power source for the entire circular food processing line. Its output end is connected to components such as the circular conveyor line 23, the horizontal pusher 225, the tilting component 2241, the material tracking group 222, the vertical pusher group 221, and the chute plate 2235 through multiple transmission branches.

[0090] Specifically, the drive motor of the power system 21 is connected to multiple cam mechanisms via the main drive shaft, including a pusher cam 2251, a pusher drive cam 22111, a sinker cam 22311, and a drive component 2221. Each cam mechanism, according to its contour curve design, drives the corresponding actuator to perform reciprocating, oscillating, or lifting movements according to a preset timing sequence.

[0091] By precisely designing the phase angle of each cam, a strict time-series linkage is formed between the intermittent feeding of the circular conveyor line 23, the horizontal pushing of the transverse pusher 225, the 90° flipping of the tilting component 2241, the dynamic movement of the material tracking group 222, the flaring of the bag support group 223, and the vertical material ejection group 221. For example, when the material container 234 moves to the discharge end, the transverse pusher 225 starts pushing; after the material enters the transfer container 2242, the tilting component 2241 starts flipping; during the flipping process, the material tracking group 222 drives the bag support group 223 to descend synchronously; after the flipping is in place, the vertical material ejection group 221 immediately starts ejecting; after the material ejection is completed, all components reset synchronously and enter the next cycle.

[0092] This timing linkage ensures seamless connection between various actions, avoiding problems such as material jamming, misalignment, or equipment interference caused by asynchronous actions, thus improving the overall operational stability and bagging success rate of the line.

[0093] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
