Description

Technical Field

[0001] The present invention relates to the field of food packaging equipment, in particular to an automatic food bagging packaging machine. Background Art

[0002] In traditional food packaging machines, the food packaging process generally includes the supply of pre-made bags, the insertion of food into the bags, and the heat-sealing of the bag openings. Because traditional bag production does not unfold the bag openings during pre-formation, resulting in flat bags, the pre-made bags must be opened wide before the food can be inserted. Traditional bag handling and turnover between these steps is primarily manual, such as bagging and sealing food by hand. This results in low efficiency, inconsistent product quality, and excessively high labor costs.

[0003] In response to traditional manual food packaging, the prior art discloses a food packaging machine that can automatically bag food. The existing automatic bagging food packaging machine is provided with a bag supply device, a bag opening device and a food feeding device. Several flat packaging bags are placed in the bag supply device, and the bag opening device mainly uses a spring and a paddle to open the bag opening of the packaging bag, and then the packaging bag is put on the food feeding device. Specifically, the two paddles are first closed by a robotic arm and inserted into the bag opening of the packaging bag. Then, the two paddles are separated from each other by the pull of the spring and the bag opening is fully opened. Then, the packaging bag is put on the discharge port of the food feeding device, and the subsequent food is pushed into the packaging bag through the food feeding device.

[0004] However, during use, it was discovered that due to the high flexibility of the packaging bag, the two paddles sometimes could not be accurately inserted into the flat opening of the packaging bag when opening the bag mouth, resulting in failure of the automatic bag removal, bag opening, or bagging processes, and the inability to properly carry out the subsequent food bagging processes. When the spring is deformed or fatigued, the two paddles cannot fully open the bag mouth to the specified size, resulting in a smaller opening when the food is bagged. This sometimes prevents the packaging bag from being properly inserted into the discharge port of the feeding device; or when the food is loaded, the edges of the packaging bag are pushed in together and folded, affecting the packaging effect. In addition, the opening is too small to properly push the food into the packaging bag, and when the food is loaded, the food can push the packaging bag directly out of the discharge port of the food feeding device, preventing the bag from being properly sealed and causing packaging failure. Therefore, existing automatic bagging food packaging machines are still unstable in many aspects of the automatic bag removal, automatic bag opening, bagging, and food bagging processes, with a high defective rate, resulting in poor food bagging effect and low packaging efficiency. Summary of the Invention

[0005] In order to improve the packaging method of the existing automatic bagging food packaging machine, optimize the process steps of automatic food bag taking, bag opening and bagging, food bagging and bag sealing, reduce the defective rate of food bag packaging, and improve the food bag packaging effect and bag packaging efficiency, the present application provides an automatic food bag packaging machine.

[0006] The automatic food bagging packaging machine provided in this application adopts the following technical solutions: An automatic food bagging packaging machine, comprising: frame; The bag supply mechanism includes a bag supply rack and a bag taking module. The bag taking module is arranged directly below the bag supply rack and is used to take out a packaging bag separately from the bag supply rack.

[0007] A bag opening mechanism, comprising a bag opening fixed frame, and a bag opening module and a bag transfer module mounted on the bag opening fixed frame; the bag opening module comprising a bag opening movable plate, two sets of bag opening arms, and a bag opening drive component for driving the two sets of bag opening arms to close or open; the bag opening movable plate is slidably connected to the bag opening fixed frame, and the two sets of bag opening arms are both mounted on the bag opening movable plate and arranged in an upper and lower distribution manner; the bag transfer module is used to drive the bag opening movable plate to slide along the bag opening fixed frame to the food conveying mechanism; A food conveying mechanism, comprising an input belt line for inputting food, a feeding module for pushing the input food into packaging bags, and an output belt line for outputting the packaged packaging bags; A corner-stiffening bag mechanism, comprising a bag-stiffening base frame, a bag-stiffening movable plate, a bag-stiffening pushing module, a four-corner-stiffening bag module, and an inward-folding module; the bag-stiffening movable plate is slidably arranged on the bag-stiffening base frame; the bag-stiffening pushing module is used to drive the bag-stiffening movable plate to slide back and forth between the feeding module and the heat-sealing mechanism; the four-corner-stiffening bag module and the inward-folding module are arranged on the bag-stiffening movable plate; the four-corner-stiffening bag module is used to keep the packaging bag fully opened when food is pushed into the packaging bag, and the inward-folding component is used to cooperate with the four-corner-stiffening bag component to fold the packaging bag inward; A heat sealing mechanism is used to perform heat-pressure sealing on the packaging bag, and a discharge end of the heat sealing mechanism is connected to the output belt line.

[0008] By adopting the above technical solution, during the bag opening and bagging process, two sets of bag opening suction cups are used to respectively absorb the upper and lower sides of the packaging bag. The bag opening drive component then closes or opens the two sets of bag opening arms, thereby achieving the process of opening the packaging bag mouth. Compared with existing spring paddles, this can greatly improve the success rate of opening the packaging bag mouth. Moreover, in the subsequent food bagging process, the bag can be continuously and fully opened by the gusseted bag-holding mechanism, which helps prevent food bagging failure caused by the bag mouth not being opened. Through the orderly connection between the various mechanisms, the automatic bag removal, bag opening and bagging, food bagging, and bag sealing process steps are jointly completed, further optimizing the packaging process of the food bagging packaging machine, which not only helps reduce the defective rate of food bagging packaging, but also helps improve the food bagging effect and efficiency.

[0009] Optionally, the bag supply rack includes a bag supply base plate and several bag supply baffles vertically arranged on the bag supply base plate, a bag supply opening is opened on the bag supply base plate, the bag supply baffles are arranged around the bag supply opening and form a bag supply channel, the picking module is arranged directly below the bag supply rack, and the inclination angle of the bag supply base plate to the horizontal plane is 10°-30°.

[0010] By adopting the above technical solution, a bag supply channel is formed around the bag supply opening using the bag supply baffle, allowing multiple bags to be stored on the bag supply rack simultaneously, eliminating the need for frequent manual replenishment. Furthermore, the inclined bag supply bottom plate significantly reduces the impact of accumulated bags on the bottom layer of bags, making it easier to remove the bottom layer of bags from the bag supply opening.

[0011] Optionally, the bag taking module includes a bag taking arm, one end of the bag taking arm is rotatably connected to the frame, and the other end of the bag taking arm is provided with a bag taking suction cup, and the bag taking suction cup is a negative pressure suction cup.

[0012] By adopting this technical solution, the bag-retrieving arm can remove a single bag from the bag supply rack above by simply rotating. This simplifies the bag-retrieving process compared to existing technologies and helps improve bag-retrieving efficiency. Secondly, the use of negative pressure suction cups to absorb the bag not only ensures 100% suction and grasping of the bag, but also does not affect the next bag during suction, ensuring that the bag-retrieving module only removes a single bag at a time. Furthermore, the suction method does not damage the bag's appearance, which helps to ensure the bag's appearance.

[0013] Optionally, the bag opening arm includes a bag opening swing arm, a bag opening cantilever and a bag opening suction cup, one end of the bag opening swing arm is rotatably connected to the bag opening movable plate, and the other end is rotatably connected to the bag opening cantilever, the bag opening cantilever is perpendicular to the bag opening swing arm and extends in a direction away from the bag opening movable plate, the bag opening suction cup is arranged on the bag opening cantilever, and the bag opening suction cups of the two groups of bag opening arms are arranged opposite to each other, and the bag opening suction cups are all negative pressure suction cups.

[0014] By adopting the above technical solution and using a negative pressure suction cup to adsorb the packaging bag, it can achieve 100% adsorption and grasping of the packaging bag, and will not damage the appearance of the packaging bag, which is conducive to ensuring the appearance of the packaging bag.

[0015] Optionally, the bag opening module also includes a suction cup leveling component, which includes a leveling connecting rod and a leveling connecting block. One end of the leveling connecting rod is rotatably connected to the bag opening movable plate, and the other end is rotatably connected to the end of the leveling connecting block. The end of the bag opening cantilever passes through the bag opening swing arm and is fixedly connected to the end of the leveling connecting block.

[0016] By adopting the above technical solution, the bag opening cantilever is limited by the leveling connecting rod and the leveling connecting block, so that the bag opening cantilever does not rotate with the swing of the bag opening swing arm, thereby effectively keeping the suction cup mouth of the bag opening suction cup horizontal, which is beneficial to preventing creases in the packaging bag due to the rotation of the bag opening suction cup and is beneficial to improving the appearance of the packaging bag.

[0017] Optionally, the bag opening driving component includes a bag opening driving member, a first bag opening gear and a second bag opening gear, the axes of the first bag opening gear and the second bag opening gear are respectively passed through by a first bag opening rotating shaft and a second bag opening rotating shaft, one end of the first bag opening rotating shaft is fixedly connected to the driving end of the bag opening driving member, and the other end is fixedly connected to the bag opening swing arm, one end of the second bag opening rotating shaft is fixedly connected to another group of the bag opening swing arms, and the first bag opening gear and the second bag opening gear are engaged with each other.

[0018] By adopting the above technical solution, utilizing the mutual meshing transmission between the first bag opening gear and the second bag opening gear, the bag opening drive component only needs to drive any one gear to rotate, so that the two sets of bag opening swing arms can rotate in different directions, so that the bag opening suction cups on the two sets of bag opening arms can move closer to or away from each other, and then cooperate with the two sets of bag opening suction cups to adsorb the upper and lower sides of the packaging bag to realize the process of opening the packaging bag.

[0019] Optionally, the feeding module includes a turntable and a pushing component, the turntable is rotatably connected to the frame, the turntable is evenly provided with several groups of feeding ports along the circumference, and feeding guide plates are provided along the circumference of the feeding ports, the feeding guide plates are located on the side of the turntable facing the bag opening mechanism, the feeding port and the feeding guide plate form a feeding channel, and the pushing component is used to push the food into the packaging bag through the feeding channel.

[0020] By adopting the above technical solution, multiple feeding channels are evenly arranged on the turntable. By rotating the disc, different feeding channels can be rotated and switched to correspond to the bag opening mechanism, which is beneficial to improving the continuity of the bag opening mechanism in placing the packaging bag on the feeding channel, and is beneficial to improving food packaging efficiency.

[0021] Optionally, the four-corner bag-stretching module includes two groups of longitudinal connecting plates slidably connected to the bag-stretching movable plate in the horizontal direction, two groups of longitudinal bag-stretching components respectively provided on the two groups of longitudinal connecting plates, and a transverse bag-stretching driving component for driving the two groups of longitudinal connecting plates to move closer to or away from each other; The longitudinal bag-supporting component includes a first support plate and a second support plate, and the first support plate and the second support plate are both slidably connected to the longitudinal connecting plate.

[0022] By adopting the above technical solution, the longitudinal drive gear is linked to the first rack and the second rack. When the longitudinal drive member drives the longitudinal drive gear to rotate, the first rack and the second rack can simultaneously drive the first support plate and the second support plate to slide in different directions, so that the upper and lower bag support bars can move closer to or farther away from each other, thereby achieving longitudinal expansion of the packaging bag. In addition, the transverse bag expansion drive member drives the two sets of longitudinal connecting plates to slide closer to or farther away from each other, so that the two sets of longitudinal bag expansion members can achieve transverse expansion of the packaging bag, thereby facilitating the packaging bag to remain fully expanded when food is pushed in, and preventing the food pushing process from being affected by the bag opening not being fully expanded.

[0023] Optionally, the transverse bag-stretching driving component includes a transverse bag-stretching driving member, two bag-stretching pulleys and a bag-stretching transmission belt. The two bag-stretching pulleys are rotatably arranged at the two ends of the bag-stretching movable plate, and the driving end of the transverse bag-stretching driving member is connected to the bag-stretching pulleys. The bag-stretching transmission belt is sleeved on the two bag-stretching pulleys, one group of the longitudinal connecting plates is connected to the upper bag-stretching transmission belt, and the other group of the longitudinal connecting plates is connected to the lower bag-stretching transmission belt.

As the bag-opening transmission belt moves, the two sets of longitudinal connecting plates can slide in opposite directions, thereby allowing the two sets of longitudinal bag-opening components to move closer or farther away from each other, and achieve horizontal expansion of the packaging bag through the upper and lower bag-opening bars. Secondly, the longitudinal connecting plates are driven to slide by the pulleys, which helps to improve the sliding stability of the longitudinal connecting plates, making the longitudinal bag-opening components more stable when expanding the packaging bag horizontally.

[0026] By adopting the above technical solution, the two groups of inward folding parts driven by the inward folding driving parts are moved closer to each other, and the relatively arranged inward folding push rods can push the packaging bag from the outside to fold inward, thereby realizing the folding of the packaging bag, which is beneficial to improving the appearance of the packaging.

[0027] In summary, the present invention has the following advantages: 1. By using two sets of bag opening suction cups to absorb the upper and lower sides of the packaging bag respectively, and then cooperating with the bag opening drive component to close or open the two sets of bag opening arms, the process of opening the packaging bag can be realized. Compared with the existing spring picks, it can greatly improve the success rate of opening the packaging bag mouth.

[0045] The following is combined with Figure 1-13 This application is described in further detail.

[0046] The embodiment of the present application discloses an automatic food bagging packaging machine. Figure 1 and Figure 2 An automatic food bagging packaging machine includes a frame 1, a bag supply mechanism 2, a bag opening mechanism 3, a food conveying mechanism 4, a gusseted bag mechanism 5, and a heat-sealing mechanism 6, all of which are mounted on the frame 1. The bag supply mechanism 2 is used to store and supply packaging bags; the bag opening mechanism 3 is used to open the bag opening of the packaging bag and convey it from the bag supply mechanism 2 to the food conveying mechanism 4; the food conveying mechanism 4 is used to convey the food to a designated location and push the food into the packaging bag; the gusseted bag mechanism 5 is used to keep the packaging bag fully open when pushing the food in, and after the food is pushed in, fold the bag opening inward and convey the folded packaging bag and the food to the heat-sealing mechanism 6; the heat-sealing mechanism 6 is used to heat-press and seal the folded packaging bag. Finally, the packaged food is conveyed out of the food bagging packaging machine via the food conveying mechanism 4.

[0047] Reference Figure 1 and Figure 3 The bag supply mechanism 2 includes a bag supply rack 21 and a bag taking module 22 , wherein the bag supply rack 21 is used to store and place a plurality of packaging bags, and the bag taking module 22 is used to take out a packaging bag from the bag supply rack 21 alone.

[0048] Specifically, the bag supply rack 21 includes a bag supply base plate 211 and several bag supply baffles 212. The bag supply base plate 211 is fixed to the frame 1 and defines a bag supply opening 2111. The bag supply baffles 212 are vertically disposed on the top side of the bag supply base plate 211 and surround the bag supply opening 2111 to form a bag supply channel. The width of the bag supply channel matches the width of the packaging bag, while the edge length of the bag supply opening 2111 is 10 mm shorter than that of the packaging bag. This allows multiple packaging bags to be stably placed on the bag supply base plate 211 and stacked upward along the bag supply baffles 212 without falling out of the bag supply opening 2111 due to their own weight.

[0049] Reference Figure 1 and Figure 3Furthermore, the bag supply bottom plate 211 is tilted. Specifically, in this embodiment, the angle of inclination of the bag supply bottom plate 211 relative to the horizontal plane is 20°. In other embodiments, the angle of inclination of the bag supply bottom plate 211 relative to the horizontal plane can be adjusted within a range of 10°-30° depending on the weight of the packaging bags. Thus, the tilted bag supply bottom plate 211 can greatly reduce the impact of accumulated packaging bags on the bottom layer of packaging bags, making it easier to remove the bottom layer of packaging bags from the bag supply opening 2111.

[0050] Reference Figure 3 The bag taking module 22 is arranged directly below the bag supply rack 21. Specifically, the bag taking module 22 includes a bag taking arm 221 and a bag taking drive. One end of the bag taking arm 221 is hinged to the frame 1. The bag taking drive is used to drive the bag taking arm 221 to rotate back and forth in a horizontal direction parallel to the bag supply base plate 211 around the hinge point. The specific bag taking drive can be a drive that can drive the bag taking arm 221 to rotate. In this embodiment, the bag taking drive is a servo motor. A plurality of bag taking suction cups 222 are provided on the bag taking arm 221. In this embodiment, the bag taking suction cups 222 are negative pressure suction cups. When it is necessary to take a bag, the bag taking drive drives the bag taking arm 221 to rotate until it is parallel to the bag supply base plate 211. At this time, the bag taking suction cups 222 contact and absorb the packaging bags on the bottom layer of the bag supply rack 21. Then the bag taking drive drives the bag taking arm 221 to rotate to a horizontal position, completing the bag supply process.

[0051] Reference Figure 4 、 Figure 5 and Figure 6 The bag opening mechanism 3 includes a bag opening fixed frame 31, a bag opening module 32 and a bag transferring module 33, wherein the bag opening fixed frame 31 is fixedly installed on the frame 1, the bag opening module 32 is slidably set on the bag opening fixed frame 31, and is used to open the bag mouth of the packaging bag taken out by the bag taking module 22, and the bag transferring module 33 is fixedly set on the bag opening fixed frame 31, and is used to drive the bag opening module 32 to slide along the bag opening fixed frame 31.

[0052] Reference Figure 4 、 Figure 5 and Figure 6 The bag opening module 32 includes a bag opening movable plate 321, two sets of bag opening arms 322, and a bag opening drive component 323. Specifically, the bag opening movable plate 321 includes a first movable plate 3211 and a second movable plate 3212. The bag opening fixed frame 31 is provided with a bag opening movable chute 311 and a bag opening movable slide rail 312. The first movable plate 3211 is connected to the second movable plate 3212 through the bag opening movable chute 311, and the bag opening outer plate is slidably connected to the bag opening movable slide rail 312. The two sets of bag opening arms 322 are rotatably mounted on the first movable plate 3211 and arranged in an upper and lower arrangement. The bag opening drive component 323 is mounted on the second movable plate 3212 and is used to drive the two sets of bag opening arms 322 to close or open.

[0053] Reference Figure 4 The bag opening arm 322 includes a bag opening swing arm 3221, a bag opening cantilever 3222 and a bag opening suction cup 3223, wherein the bag opening swing arm 3221 is rotatably connected to the first movable plate 3211, and the other end is rotatably connected to the bag opening cantilever 3222, the bag opening cantilever 3222 is perpendicular to the bag opening swing arm 3221 and extends in a direction away from the first movable plate 3211, and the bag opening suction cup 3223 is arranged on the bag opening cantilever 3222, wherein the suction cup mouth of the bag opening suction cup 3223 is arranged opposite to the suction cup mouth of the bag opening suction cup 3223 on the other group of bag opening arms 322. In this embodiment, the bag opening suction cup 3223 also uses a negative pressure suction cup, so that the upper and lower sides of the packaging bag can be vacuum adsorbed by the bag opening suction cups 3223 on the two groups of bag opening arms 322.

[0054] Reference Figure 4 Furthermore, to keep the suction cup opening of the bag opening suction cup 3223 always horizontal, the bag opening module 32 is further provided with a suction cup leveling component 324. Specifically, the suction cup leveling component 324 includes a leveling link 3241 and a leveling connection block 3242. One end of the leveling link 3241 is rotatably connected to the first movable plate 3211, and the other end is rotatably connected to the end of the leveling connection block 3242. The end of the bag opening cantilever 3222 passes through the bag opening swing arm 3221 and is fixedly connected to the other end of the leveling connection block 3242. When the bag opening swing arm 3221 swings, the bag opening cantilever 3222 is limited by the leveling connecting rod 3241 and the leveling connecting block 3242, so that the bag opening cantilever 3222 does not rotate with the swing of the bag opening swing arm 3221, thereby effectively keeping the suction cup mouth of the bag opening suction cup 3223 horizontal, which is beneficial to prevent the packaging bag from being creased due to the rotation of the bag opening suction cup 3223, thereby affecting the appearance of the packaging bag.

[0055] Reference Figure 5 and Figure 6The bag opening drive component 323 includes a bag opening drive member 3231, a first bag opening gear 3232, and a second bag opening gear 3233. A first bag opening rotating shaft 3234 and a second bag opening rotating shaft 3235 are respectively passed through the axes of the first bag opening gear 3232 and the second bag opening gear 3233. Specifically, the bag opening drive member 3231 is disposed on the side of the second movable plate 3212 facing away from the bag fixing frame 31. The first bag opening gear 3232 and the second bag opening gear 3233 are respectively mounted between the second movable plate 3212 and the bag fixing frame 31 via the first bag opening rotating shaft 3234 and the second bag opening rotating shaft 3235. One end of the first bag-opening rotating shaft 3234 passes through the second movable plate 3212 and is connected to the driving end of the bag-opening driving member 3231. The other end of the first bag-opening rotating shaft 3234 passes through the movable bag-opening chute 311 of the bag-opening fixed frame 31 and is fixedly connected to the bag-opening swing arm 3221. One end of the second bag-opening rotating shaft 3235 is rotatably connected to the second movable plate 3212, and the other end also passes through the movable bag-opening chute 311 of the bag-opening fixed frame 31 and is fixedly connected to the other set of bag-opening swing arms 3221. The first bag-opening gear 3232 and the second bag-opening gear 3233 mesh with each other. In this embodiment, the bag-opening driving member 3231 is specifically a servo motor.

[0056] Reference Figure 4 、 Figure 5 and Figure 6 When the bag opening drive component 3231 is started, it drives the first bag opening shaft 3234 and the bag opening swing arm 3221 to start rotating clockwise or counterclockwise, and drives the second bag opening shaft 3235 and the other set of bag opening swing arms 3221 to rotate in the opposite direction through the transmission of the first bag opening gear 3232 and the second bag opening gear 3233. At this time, the two sets of bag opening cantilevers 3222 and the bag opening suction cups 3223 can approach or move away from each other, and cooperate with the two sets of bag opening suction cups 3223 to adsorb the upper and lower sides of the packaging bag, thereby realizing the process of opening the packaging bag.

[0057] Reference Figure 5 and Figure 6 The bag transfer module 33 includes a bag transfer driver 331, two bag transfer pulleys 332, and a bag transfer belt 333. The two bag transfer pulleys 332 are rotatably mounted on either end of the bag opening fixed frame 31. The driving end of the bag transfer driver 331 is connected to the axis of one of the bag transfer pulleys 332. Specifically, the bag transfer driver 331 utilizes a servo motor. The bag transfer belt 333 is mounted on the two bag transfer pulleys 332, and the second movable plate 3212 is fixedly connected to the bag transfer belt 333. Thus, the bag transfer driver 331, through the transmission of the bag transfer pulleys 332 and the bag transfer belt 333, drives the bag opening movable plate 321 to slide along the bag opening movable slide rail 312, thereby transporting the opened packaging bag from the bag supply mechanism 2 to the food conveying mechanism 4.

[0058] Reference Figure 1The food conveying mechanism 4 includes an input belt line 41, a feeding module 42, and an output belt line 43. The input belt line 41 is arranged on one side of the frame 1. The output end of the input belt line 41 is connected to the feeding module 42 and is used to input food into the feeding module 42; the feeding module 42 is used to feed an appropriate amount of food into the packaging bag. The output belt line 43 is arranged at the output end of the heat sealing mechanism 6. When the heat sealing mechanism 6 completes the heat-pressure sealing of the packaging bag, the output belt line 43 can output the heat-sealed packaging bag.

[0059] Reference Figure 2 and Figure 7 The feeding module 42 includes a turntable 421 and a pushing component 422. The turntable 421 is provided with a plurality of feeding channels evenly arranged along its circumference. The pushing component 422 is used to push the food on the input belt line 41 into the packaging bag through the feeding channels. Specifically, the turntable 421 is rotatably connected to the frame 1. The turntable 421 is provided with a plurality of feeding ports 4211 evenly arranged along its circumference. Feeding guide plates 4212 are provided around the feeding ports 4211. The feeding guide plates 4212 are located on the side of the turntable 421 facing the bag opening mechanism 3. The feeding ports 4211 and the feeding guide plates 4212 form a feeding channel. Furthermore, the opening of the feed channel is larger than the cross-sectional area of ​​the food but smaller than the open area of ​​the bag opening. Thus, when the bag opening module 32 opens the bag and is moved to the feed module 42 via the bag transfer module 33, the opened bag can be placed on the feed guide plate 4212, and the feed opening 4211 corresponds to the bag opening. At this point, the food can be fed into the bag through the feed opening 4211 along the feed channel. At the same time, the turntable 421 can be rotated to switch between different feed channels corresponding to the bag opening mechanism 3, thereby facilitating the continuous placement of the bag on the feed channel and improving food packaging efficiency.

The pushing drive assembly 4223 includes a pushing drive member, a pushing pulley, and a pushing transmission belt. The pushing frame 4221 is fixedly connected to the pushing transmission belt. The pushing drive member drives the pushing pulley and the pushing transmission belt to move, thereby driving the pushing frame 4221 to slide along the pushing slide 11, so that the pushing rod 4222 can slide back and forth along the feeding channel.

[0061] Reference Figure 8 and Figure 9The corner pouch-stiffening mechanism 5 includes a pouch-stiffening base frame 51, a pouch-stiffening movable plate 52 mounted on the pouch-stiffening base frame 51, and a pouch-stiffening push module 53.

The pouch-stiffening base frame 51 is provided with a base frame slide 511, which extends horizontally from the feeding module 42 toward the heat-sealing mechanism 6. The pouch-stiffening movable plate 52 is slidably connected to the pouch-stiffening base frame 51 via the base frame slide 511. The pouch-stiffening push module 53 is used to drive the pouch-stiffening movable plate 52 to slide along the base frame slide 511. The four-corner pouch-stiffening module 54 is used to keep the package fully open when food is pushed into the package, while the inward-folding module 55 cooperates with the four-corner pouch-stiffening module 54 to fold the package inward.

The two sets of longitudinal bag-stretching components 542 are respectively provided on the two sets of longitudinal connecting plates 541 and arranged opposite each other. Specifically, the longitudinal bag-stretching components 542 include a first support plate 5421 and a second support plate 5422. The longitudinal connecting plates 541 are provided with a connecting plate slide rail 5411 extending longitudinally. The first support plate 5421 and the second support plate 5422 are both slidably connected to the longitudinal connecting plate 541 via the connecting plate slide rail 5411. An upper bag-supporting bar 54211 is provided at the top of the first support plate 5421, and a lower bag-supporting bar 54221 is provided at the top of the second support plate 5422.

The first rack 54212 and the second rack 54222 are meshed and linked to each other via a longitudinal drive wheel. The axis of the longitudinal drive gear 5423 is connected to a longitudinal bag-supporting drive member. In this embodiment, the longitudinal bag-supporting drive member uses a servo motor. When the longitudinal bag-supporting driving member drives the longitudinal driving gear 5423 to rotate, through the linkage of the first rack 54212 and the second rack 54222, the first support plate 5421 and the second support plate 5422 will drive the upper bag-supporting strip 54211 and the lower bag-supporting strip 54221 to move closer to or away from each other in the longitudinal direction, thereby realizing the longitudinal opening or closing of the packaging bag.

[0063] Reference Figure 8 、 Figure 9 and Figure 10The transverse bag-supporting drive assembly 543 includes a transverse bag-supporting drive element 5431, two bag-supporting pulleys 5432, and a bag-supporting transmission belt 5433. The two bag-supporting pulleys 5432 are rotatably mounted on both ends of the bag-supporting movable plate 52. The driving end of the transverse bag-supporting drive element 5431 is connected to the axis of one of the bag-supporting pulleys 5432. Specifically, a servo motor is used for the transverse bag-supporting drive element 5431. The bag-supporting transmission belt 5433 is mounted on the two bag-supporting pulleys 5432. One set of longitudinal connecting plates 541 is connected to the upper bag-supporting transmission belt 5433, while the other set of longitudinal connecting plates 541 is connected to the lower bag-supporting transmission belt 5433. When the transverse bag-stretching driving member 5431 drives the bag-stretching pulley 5432 to rotate, the bag-stretching transmission belt 5433 will make a circular motion around the two sets of bag-stretching pulleys 5432. Since the two sets of longitudinal connecting plates 541 are respectively connected to the upper and lower sides of the bag-stretching transmission belt 5433, the bag-stretching transmission belt 5433 can drive the two sets of longitudinal connecting plates 541 to slide closer to or away from each other along the first transverse slide rail 521, thereby realizing the transverse expansion of the packaging bag.

[0064] Reference Figure 8 、 Figure 9 and Figure 11 The inward folding module 55 includes two sets of inward folding components 551 and an inward folding drive component 552. The inward folding components 551 include an inward folding connector 5511. The bag-supporting movable plate 52 is provided with a second transverse slide rail 522. The inward folding connector 5511 is slidably connected to the bag-supporting movable plate 52 via the second transverse slide rail 522. The top of the inward folding connector 5511 is provided with an inward folding push rod 5512. The inward folding push rod 5512 is "L"-shaped, and the inward folding push rods 5512 of the two sets of inward folding components 551 are arranged opposite each other. Specifically, the inward folding push rod 5512 is located between the upper bag-supporting bar 54211 and the lower bag-supporting bar 54221. The inward folding push rod 5512 is used to push the middle part of the side of the packaging bag to form an inward fold.

[0065] Reference Figure 8 and Figure 9 The inward folding drive component 552 includes an inward folding drive member 5521, two inward folding pulleys 5522, and an inward folding transmission belt 5523. The two inward folding pulleys 5522 are rotatably disposed at both ends of the bag-supporting movable plate 52. The driving end of the inward folding drive member 5521 is connected to the axis of one of the inward folding pulleys 5522.

[0066] When the inward folding driving member 5521 drives the inward folding pulley 5522 to rotate, the inward folding transmission belt 5523 will make a circular motion around the two inward folding pulleys 5522. Since the two groups of inward folding connecting members 5511 are respectively connected to the upper and lower sides of the inward folding transmission belt 5523, the inward folding transmission belt 5523 can drive the two groups of inward folding connecting members 5511 to slide closer to or away from each other along the second transverse slide rail 522, thereby pushing the side of the packaging bag and folding it inward.

[0067] Reference Figure 12 and Figure 13 The heat sealing mechanism 6 includes a heat sealing frame 61, a heat sealing module 62 and a heat sealing driving module 63, wherein heat sealing guide rods 611 are provided on both sides of the heat sealing frame 61, and the heat sealing guide rods 611 extend upward in the vertical direction. The heat sealing module 62 includes a heat sealing fixed component 621 and a heat sealing movable component 622, and the heat sealing fixed component 621 is fixedly arranged on the top of the heat sealing guide rod 611, and the heat sealing movable component 622 is slidably connected to the heat sealing guide rod 611. The heat sealing driving module 63 is used to drive the heat sealing movable component 622 to slide along the heat sealing guide rod 611.

[0068] Reference Figure 12 and Figure 13 The heat-sealing fixed component 621 includes a heat-sealing fixed plate and a fixed heat-pressing block 6212, while the heat-sealing movable component 622 includes a heat-sealing movable plate 6221 and a movable heat-pressing block 6222.

The ends of the heat-sealing movable plate 6221 are respectively sleeved around the sides of the heat-sealing guide rods 611 on either side and slidably connected to the heat-sealing guide rods 611. The fixed heat-pressing block 6212 and the movable heat-pressing block 6222 are arranged in correspondence with each other. When the heat-sealing drive module 63 drives the heat-sealing movable component 622 to slide upward, the movable heat-pressing block 6222 and the fixed heat-pressing block 6212 are pressed against each other, achieving heat-sealing sealing of the packaging bag.

[0069] Reference Figure 12 and Figure 13 The heat sealing drive module 63 includes a heat sealing drive member 631 and a heat sealing connecting rod 632, wherein the middle part of the heat sealing connecting rod 632 is rotatably fixed to the middle part of the heat sealing frame 61, and the two ends of the heat sealing connecting rod 632 are movably connected to the bottom top side of the heat sealing frame 61 and the bottom side of the heat sealing movable plate 6221 respectively.

[0070] The implementation principle of an automatic food bagging packaging machine in the embodiment of the present application is as follows: First, the bag taking arm 221 rotates to make the bag taking suction cup 222 contact with the bottom packaging bag on the bag supply rack 21, and the bag taking suction cup 222 absorbs a single packaging bag through negative pressure. The bag taking arm 221 rotates to a horizontal position again, and now a single packaging bag is taken out from the bag supply rack 21, completing the bag taking action.

[0071] The bag opening driving component 323 drives the two bag opening arms 322 to approach each other, and enables the bag opening suction cups 3223 on the upper and lower sides to fully adsorb the upper and lower sides of the packaging bag. Then the bag opening driving component 323 drives in the opposite direction to move the two bag opening arms 322 away from each other, completing the bag opening action. Then, the bag opening module 32 is moved together with the packaging bag to the feeding module 42 through the bag moving module 33, and is mounted on the feeding guide plate 4212 to complete the bag opening and bagging actions.

[0072] The food is input into the packaging machine through the input belt line 41. As the turntable 421 rotates, the feeding channel with the packaging bag rotates to a specified position, and the food on the input belt line 41 is pushed into the packaging bag by the pushing module.

[0073] Before the food is pushed into the packaging bag, the bag-supporting movable plate 52, through the push of the bag-supporting pushing module 53, drives the upper bag-supporting bars 54211 and the lower bag-supporting bars 54221 of the four-corner bag-supporting module 54 to be inserted into the packaging bag. Then, through the drive of the longitudinal bag-supporting driving member and the transverse bag-supporting driving member 5431, the two sets of upper bag-supporting bars 54211 and the two sets of lower bag-supporting bars 54221 are fully separated, thereby supporting the four corners of the packaging bag and allowing the food to be pushed in smoothly. After the food is pushed into the packaging bag, the longitudinal bag-supporting driving member and the transverse bag-supporting driving member 5431 simultaneously drive the two sets of upper bag-supporting bars 54211 and the two sets of lower bag-supporting bars 54221 to close together. At the same time, the inward folding driving member 5521 drives the two sets of inward folding components 551 toward each other, thereby folding the packaging bag containing the food inward.

[0074] While the packaging bag is folded inward, the pushing module cooperates with the gusset bag insertion mechanism 5 to push the packaging bag into the heat sealing mechanism 6. Finally, the packaging bag is heat-pressed and sealed by the heat sealing mechanism 6, and then output by the output belt line 43, thereby realizing the packaging and output action of the packaging bag.

[0075] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
