Description

Technical Field

[0001] This application relates to the technical field of packaging equipment, and in particular to a fully automatic bag-feeding packaging machine. Background Technology

[0002] In today's booming health food market, various snack products are highly favored by consumers. As consumers' pursuit of a higher quality of life continues to increase, they are placing more diverse demands on food packaging. They not only expect packaging to effectively guarantee product freshness and safety, but also increasingly value ease of use and visual appeal. As a crucial piece of equipment in the food packaging industry, optimizing the performance of pre-packaging machines is essential to meeting market demands and improving packaging efficiency.

[0003] Currently, a common bag-packing machine mainly consists of a base, a rotating sleeve, and a rotating disk. The rotating sleeve is rotatably mounted on the base, and the rotating disk is fixed to the upper end of the rotating sleeve. A drive assembly inside the base drives the rotating sleeve to rotate. The rotating disk is equipped with a clamping assembly for holding the packaging bags. Around the base, bag-feeding, bag-opening, filling, bag-sealing, and discharging assemblies are arranged in sequence. The bag-feeding assembly includes a feeding conveyor belt and a feeding negative pressure suction cup. The feeding conveyor belt is inclined downwards for stacking packaging bags, and the feeding negative pressure suction cup can move up and down under the action of a cylinder to suction the topmost packaging bag.

[0004] However, problems arise when feeding larger, softer bags. Due to static electricity, when using the negative pressure suction cup to grip a bag on the top side of the feed nozzle, another bag on the bottom side may adhere tightly, resulting in two bags being gripped simultaneously. The subsequent gripping components can only grip one bag at a time, unable to handle two bags at once. Furthermore, bags attracted by static electricity may detach during gripping, scattering the originally tightly arranged bags on the feed conveyor belt and affecting subsequent gripping. Both situations require manual intervention, severely impacting packaging efficiency and indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a fully automatic bag feeding and packaging machine to solve the problem in the above-mentioned related technologies that when feeding large and soft packaging bags, static electricity may cause two packaging bags to be clamped at the same time, which requires manual intervention to sort them and ultimately affects the overall packaging efficiency.

[0006] The fully automatic bag-feeding packaging machine provided in this application adopts the following technical solution:

[0007] A fully automatic bag-feeding packaging machine includes a base, a rotating disk rotatably mounted on the upper surface of the base, and a drive component that drives the rotating disk to rotate. Several clamping components for holding packaging bags are arranged on the outer periphery of the rotating disk. A bag-feeding assembly, a bag-opening assembly, a filling assembly, a heat-sealing assembly, and a discharging assembly are sequentially arranged around the rotating disk on the base. The bag-feeding assembly includes a clamping component, two vertical plates fixed side-by-side on the upper surface of the base, and a lifting component located between the two vertical plates that can move up and down. A barrier plate is fixed on the same vertical side of the two vertical plates, and a limiting component is provided on the vertical side away from the barrier plate. The lifting component is inclined downwards towards the barrier plate and can provide support. Packaging bags stacked between two vertical plates; the clamping component includes a connector, a horizontal bar above the vertical plates, and a first power component mounted on a base. A fixing block is fixed on the horizontal bar between the two vertical plates, and a clamping suction cup and a pressing part are fixed on the fixing block. An output shaft is fixed on the first power component, and the first power component drives the fixing block to rotate around the output shaft through the connector. When the fixing block rotates downward, the clamping suction cup clamps the uppermost packaging bag, and when it rotates upward, the pressing part presses the upper side of the packaged bag to bend it. The base is provided with a clamping component to clamp the packaging bag clamped by the clamping suction cup onto the clamping component.

[0008] By adopting the above technical solution, the lifting component in the upper bag assembly tilts to support the stacked packaging bags. When the gripping suction cup of the clamping component grips the top packaging bag, the pressing part can press the upper side of the packaging bag to bend it, reducing the situation where two packaging bags are gripped at the same time due to electrostatic adsorption. It also prevents the packaging bags from falling off during the gripping process and causing the stack to scatter. This design eliminates the need for manual intervention to organize the packaging, greatly improving packaging efficiency and meeting the market demand for efficient and stable packaging equipment.

[0009] Optionally, the connecting component includes a connecting plate, a transmission rod fixed to the outer periphery of the output shaft, and a connecting rod fixedly connected to the end of the transmission rod away from the output shaft; the end of the connecting rod away from the transmission rod is rotatably connected to one end of the connecting plate; a pressing rod located above the connecting rod is rotatably sleeved on the outer periphery of the output shaft; an elastic element that drives the pressing rod to rotate downward is provided above the base; a connecting shaft rotatably connected to the middle of the connecting plate is fixed on the pressing rod; the end of the crossbar near the output shaft is fixedly connected to the end of the connecting plate away from the connecting rod; a limiting wheel is fixedly provided on the bottom surface of the pressing rod; a limiting protrusion is fixedly provided above the base located below the limiting wheel; the axes of the crossbar, the output shaft, and the connecting shaft are parallel to each other; the first power element drives the pressing rod and the crossbar to rotate around the axis of the output shaft; when the limiting wheel and the upper surface of the limiting protrusion are pressed together, the output shaft drives the crossbar to rotate around the axis of the connecting shaft.

[0010] By adopting the above technical solution, the connecting component, through the coordinated operation of components such as the connecting plate, transmission rod, connecting rod, and extrusion rod, utilizes the elastic element to drive the extrusion rod to rotate downwards. Combined with the clamping action of the limiting wheel and the limiting protrusion plate, the first power component, while driving the extrusion rod and crossbar to rotate around the output shaft, can also drive the crossbar to rotate around the connecting shaft under specific conditions. This composite motion allows the gripping suction cup and pressing part in the gripping component to more accurately and flexibly complete the gripping and pressing actions of the packaging bag, effectively reducing gripping abnormalities caused by electrostatic adsorption, improving the accuracy and stability of packaging feeding, and ensuring the overall operating efficiency and packaging quality of the fully automatic bag packaging machine.

[0011] Optionally, a limiting gap is provided between the barrier plate and the vertical plate, and a pressing rod located within the limiting gap is rotatably mounted on the barrier plate. The pressing rod is used to limit the side edge of the uppermost packaging bag near the barrier plate. A proximity switch located below the pressing rod and capable of controlling the operation of the first power component is fixed on the barrier plate. After the clamping suction cup clamps the uppermost packaging bag, the pressing rod rotates downward and abuts against the upper surface of the proximity switch. When the lifting plate moves up, the pressing rod can rotate upward and separate from the upper surface of the proximity switch.

[0012] By adopting the above technical solution, the proximity switch on the barrier plate is cleverly designed. When the suction cup grips the topmost packaging bag, the pressing rod rotates downwards to engage with the proximity switch, controlling the operation of the first power component and achieving automated operation. Conversely, when the lifting plate moves upwards, the pressing rod rotates upwards to disengage from the proximity switch, ensuring the orderly operation of each component. This design effectively improves the automation level and operational accuracy of the packaging machine, reduces manual intervention, and guarantees packaging efficiency and quality.

[0013] Optionally, an inclined support platform is fixed on the upper surface of the base, the upper surface of the support platform is parallel to the upper surface of the lifting plate, and an adjusting member is provided on the support platform to adjust the distance between the two vertical plates.

[0014] By adopting the above technical solution, the support platform is tilted and parallel to the upper surface of the lifting plate, providing stable support for the packaging bags, ensuring good stacking, and facilitating subsequent clamping operations. The bottom side of the barrier plate is fixedly connected to the upper surface of the support platform, enhancing the structural stability. Furthermore, the adjustable component that allows for adjusting the distance between the two vertical plates can flexibly adjust the distance according to different sizes of packaging bags, giving the packaging machine greater versatility and adaptability. It can meet the packaging needs of various specifications of packaging bags, eliminating the need for frequent replacement of equipment parts, effectively reducing production costs, and improving the efficiency and flexibility of the packaging machine.

[0015] Optionally, the fixing block can slide back and forth along the length of the crossbar, and the pressing part has a limiting notch on the side facing the base for the upper edge of the vertical plate to be inserted. When the pressing part rotates, the upper edge of the vertical plate rotates synchronously relative to the limiting notch.

[0016] By adopting the above technical solution, the fixing block can slide back and forth along the length of the crossbar, allowing the positions of the gripping suction cup and the pressing part to be flexibly adjusted. This better adapts to packaging bags of different sizes and stacking states, improving the accuracy of gripping and pressing. A limiting notch is provided on the side of the pressing part facing the base for the upper edge of the vertical plate to be inserted. When the pressing part rotates, the upper edge of the vertical plate rotates synchronously relative to the limiting notch. This cooperation method further enhances the stability of the pressing part in pressing the packaging bag.

[0017] Optionally, the limiting component includes a limiting rod that slides on the inner walls of the two vertical plates close to each other. The installation direction of the limiting rod is perpendicular to the upper surface of the lifting plate, and the sliding direction is parallel to the upper surface of the lifting plate. A locking component is provided on the outside of the vertical plate to fix the sliding state of the limiting rod.

[0018] By adopting the above technical solution, this setup allows for flexible adjustment of the limit rod position, adapting to the stacking requirements of packaging bags of different widths, effectively limiting the packaging bags and preventing them from scattering. The locking mechanism on the outside of the vertical plate fixes the sliding state of the limit rod, ensuring its stability after adjustment to the appropriate position. This prevents the limit rod from affecting the stacking and gripping of packaging bags during the packaging process, ensuring the stable and efficient operation of the fully automatic bag-feeding packaging machine.

[0019] Optionally, the bag opening assembly includes a vertical rod fixed to a base, a support plate fixed vertically to the upper part of the vertical rod, an extension plate fixed to one vertical surface of the support plate, two suction cup holders opposite each other arranged below the extension plate, negative pressure suction cups fixed to the sides of the two suction cup holders that are close to each other, and a first driving source provided on the extension plate to drive the two suction cup holders to slide back and forth in the direction of closeness; a fixed rod is slidably provided on the side of the support plate away from the vertical rod, and a second power component is installed to drive the fixed rod to slide, the length direction of the fixed rod is perpendicular to the axis of the vertical rod, and the sliding direction is parallel to the axis of the vertical rod; a bag opening component is provided on the fixed rod between the two suction cup holders.

[0020] By adopting the above technical solution, the vertical rod, support plate, etc. form a stable frame. The two suction cup frames and negative pressure suction cups arranged opposite each other under the extension plate can slide back and forth in the direction of mutual approach under the drive of the first drive source, accurately adsorbing both sides of the packaging bag to realize the bag opening action. At the same time, the sliding fixed rod on the support plate and the second power component that drives its sliding, together with the bag opening component located between the two suction cup frames on the fixed rod, can further assist in opening the bag after adsorbing it, ensuring that the packaging bag is fully opened.

[0021] Optionally, the bag opening component includes two inner clamping rods rotatably mounted on a fixed rod, and a first power source that drives the two inner clamping rods to rotate towards and away from each other. The two inner clamping rods are located between two suction cup frames. A vertically downward outer clamping rod is rotatably mounted on the opposite sides of the two inner clamping rods. A second power source is provided on the inner clamping rods to drive the outer clamping rods to reciprocate towards the inner clamping rods.

[0022] By adopting the above technical solution, two inner clamping rods are rotatably mounted on a fixed rod, driven by a first power source to rotate in opposite directions. Located between two suction cup frames, they further assist in opening the packaging bag, ensuring a better opening effect. Simultaneously, the vertically downward-facing outer clamping rods, rotatably mounted on the opposite sides of the inner clamping rods, can reciprocate towards the inner clamping rods under the action of a second power source, better gripping the packaging bag and enhancing the stability of the opening process. This design makes the bag opening process more precise and reliable, effectively improving the efficiency and success rate of the bag opening stage of the fully automatic bag-feeding packaging machine, and ensuring the smooth progress of subsequent packaging processes.

[0023] Optionally, an arc-shaped plate is installed above the base. The heat-sealing assembly includes a first heat-sealing component and a second heat-sealing component fixed on the arc-shaped plate. The first heat-sealing component is located on the side near the filling assembly, and the second heat-sealing component is located on the side near the upper bag assembly. The discharging assembly includes a guide plate located below the second heat-sealing component and a conveyor belt fixed on the base. The lower edge of the guide plate is fixed to the upper side edge of the conveyor belt near the rotating disk, and the guide plate is inclined upward in the direction near the rotating disk.

[0024] By adopting the above technical solution, a first heat-sealing element and a second heat-sealing element are set on the arc-shaped plate, close to the filling component and the bag feeding component, respectively. This reasonable layout realizes the heat-sealing operation of the packaging bag at different stages. During heat sealing, the packaging bag passes through the first and second heat-sealing elements sequentially. The first heat-sealing element acts on the packaging bag earlier than the second heat-sealing element, and the heat-sealing temperature of the first heat-sealing element is higher than that of the second heat-sealing element. The packaging bag undergoes two heat seals, which not only improves the heat seal strength but also allows the temperature of the bag opening to be rapidly reduced during the second heat seal, thus reducing the probability of deformation. In the discharge component, the guide plate located below the second heat-sealing element is inclined upwards, and its lower edge is fixed to the upper side edge of the conveyor belt near the rotating disk. This structure allows the sealed packaging bag to smoothly slide onto the conveyor belt through the guide plate, achieving orderly discharge and preventing the packaging bags from scattering or piling up. This ensures that the entire packaging process of the fully automatic bag packaging machine is efficient and continuous, improving production efficiency and packaging quality.

[0025] Optionally, a first column near the upper bag assembly and a second column near the filling assembly are fixedly provided on the base. The bottom surfaces of both ends of the arc-shaped plate are fixedly connected to the upper parts of the first and second columns, respectively. The clamping component includes a clamping claw for clamping the packaging bag on the suction cup and a third power source installed in the first column. A conveying shaft extending to the outside of the first column is fixedly provided on the third power source. The third power source is used to drive the clamping claw to rotate around the conveying shaft. The clamping claw can rotate from the vertical plate towards the clamping component on the rotating disk.

[0026] By adopting the above technical solution, a first column and a second column are respectively set on the base near the bag opening component and the filling component, and the bottom surfaces of both ends of the arc-shaped plate are fixedly connected to them, providing stable support for the heat sealing component and ensuring stable heat sealing operation. The clamping component is ingeniously designed. The clamping claw rotates around the conveyor shaft under the drive of the third power source, and can flexibly rotate from the vertical plate towards the clamping component on the rotating disk, accurately clamping the packaging bag on the suction cup, realizing the smooth transfer of the packaging bag between the components, improving the automation level and smooth operation of the fully automatic bag packaging machine, and effectively improving packaging efficiency and quality.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] During operation, the lifting components in the bag-feeding packaging machine tilt to support the stacked packaging bags. When the gripping suction cups of the clamping components grip the topmost packaging bag, the pressing part can press down on the upper side of the packaging bag to bend it, reducing the possibility of electrostatic adsorption causing two packaging bags to be gripped simultaneously. It also prevents packaging bags from falling off during the gripping process and causing the stack to scatter. This design eliminates the need for manual intervention, greatly improving packaging efficiency and meeting the market demand for efficient and stable packaging equipment.

Detailed Implementation

[0046] The present application will be further described in detail below with reference to all the accompanying drawings.

[0047] Example:

[0048] Reference Figure 1 A fully automatic bag packaging machine includes a base 1, a rotating disk 11 rotatably mounted on the upper surface of the base 1, and a driving component (not shown in the figure) that drives the rotating disk 11 to rotate. The rotating disk 11 has a number of clamping components 12 that clamp the packaging bags evenly distributed on its outer periphery. The base 1 is arranged around the rotating disk 11 in sequence as a bag feeding assembly 2, a bag opening assembly 3, a material injection assembly 13, a heat sealing assembly 4, and a material discharge assembly 5.

[0049] The driving component is a conventional motor fixed on the lower side of the base 1, and the clamping component 12 is a conventional clamping structure. The clamping component 12 is mainly used to clamp the two opposite edges of the opening of the packaging bag. The specific structures of the driving component and the clamping component 12 will not be described in detail here.

[0050] The pre-stacked packaging bags are automatically fed onto the clamping member 12 on the rotating disk 11 via the bag loading component 2. Then, the rotating disk 11 drives the clamping member 12 holding the packaging bags to rotate. The clamped packaging bags pass through the opening component to open the bag mouth, the material on the filling component 13 to inject material into the packaging bag, the heat sealing component 4 to seal the bag mouth, and the discharging component 5 to remove the packaged packaging bags from the base 1.

[0051] Reference Figure 2 , Figure 3 and Figure 4 The upper bag assembly 2 includes a clamping component 21, a gripping component 22, two vertical plates 23 fixed side by side on the upper surface of the base 1, and a lifting component 24 located between the two vertical plates 23 that can move up and down; a barrier plate 25 is fixed on the same vertical side of the two vertical plates 23, and a limiting component 26 is provided on the vertical side away from the barrier plate 25.

[0052] The lifting member 24 is inclined downward toward the barrier plate 25 and can support the packaging bags stacked on the two vertical plates 23; the clamping member 22 is used to clamp the packaging bag on the receiving plate and between the two vertical plates 23 at the top; and the clamping member 21 is used to clamp the packaging bag clamped by the clamping member 22 onto the clamping member 12.

[0053] Reference Figure 3 and Figure 4 The lifting component 24 includes a lifting plate 241 that can slide up and down and a second drive source 242 fixed on the base 1. The lifting plate 241 is inclined downward towards the direction of the barrier plate 25. The second drive source 242 is a drive cylinder 2421 fixed on the lower side of the base 1. The end of the telescopic rod of the drive cylinder 2421 is fixedly connected to the bottom surface of the lifting plate 241. When the bag-loading mechanism is running, each time the uppermost packaging bag is gripped by the clamping component 22, the cylinder returns to drive the lifting plate 241 to move upward a certain height, lifting the packaging bag to a position that is easy for the clamping component 22 to grip.

[0054] Reference Figure 4 and Figure 5 The clamping component 22 includes a connector 221, a horizontal bar 222 located above the vertical plate 23, and a first power component 223 mounted on the base 1. A fixing block 224 located between the two vertical plates 23 is fixed on the horizontal bar 222. A clamping suction cup 226 and a pressing part 225 are fixed on the fixing block 224. An output shaft 2231 is fixed on the first power component 223. The first power component 223 drives the fixing block 224 to rotate around the output shaft 2231 through the connector 221. When the fixing block 224 rotates downward, the clamping suction cup 226 clamps the uppermost packaging bag. When it rotates upward, the pressing part 225 presses the upper side of the packaging bag to bend it.

[0055] A frame 14 is fixed on the upper surface of the base 1. The first power component 223 is a combination structure of a power motor and a reducer fixed in the frame 14. This is a conventional drive structure used to drive the output shaft 2231 extending to the outside of the frame 14 to rotate, which will not be described in detail here.

[0056] Reference Figure 6 and Figure 7 The connecting member 221 includes a connecting plate 2211, a transmission rod 2212 fixed on the outer periphery of the output shaft 2231, and a connecting rod 2213 fixedly connected to the end of the transmission rod 2212 away from the output shaft 2231; the end of the connecting rod 2213 away from the transmission rod 2212 is rotatably connected to one end of the connecting plate 2211.

[0057] An extrusion rod 2214 located above the connecting rod 2213 is rotatably sleeved on the outer periphery of the output shaft 2231. An elastic element 2215 that drives the extrusion rod 2214 to rotate downward is provided above the base 1. The elastic element 2215 is specifically a tension spring, wherein the upper end of the tension spring is fixedly connected to the bottom surface of the extrusion rod 2214, and the lower end of the tension spring is fixedly connected to the lower part of the frame 14.

[0058] A connecting shaft 22141, which is rotatably connected to the middle of the connecting plate 2211, is fixed on the extrusion rod 2214. The end of the crossbar 222 near the output shaft 2231 is fixedly connected to the end of the connecting plate 2211 away from the connecting rod 2213. A limiting wheel 22142 is fixed on the bottom surface of the extrusion rod 2214. A limiting protrusion 141 located below the limiting wheel 22142 is fixed on the top of the base 1. The axes of the crossbar 222, the output shaft 2231, and the connecting shaft 22141 are parallel to each other.

[0059] The rotation of the gripping suction cup 226 is divided into two steps: First, the first power component 223 drives the squeezing rod 2214, connecting rod 2213, connecting plate 2211 and crossbar 222 to rotate around the axis of the output shaft 2231. At this time, the limiting wheel 22142 is still not in contact with the upper surface of the limiting protrusion 141. Second, the output shaft 2231 continues to drive the transmission rod 2212 and connecting rod 2213 to rotate downward. At this time, the connecting plate 2211 can no longer rotate around the output shaft 2231, but the connecting plate 2211 can rotate around the axis of the connecting shaft 22141, further driving the gripping suction cup 226 to rotate, so that the gripping suction cup 226 can fully clamp and hold the packaging bag at the top.

[0060] Reference Figure 8 and Figure 9 An inclined support platform 15 is fixed on the upper surface of the base 1. The upper surface of the support platform 15 is parallel to the upper surface of the lifting plate 241. The bottom side of the barrier plate 25 is fixedly connected to the upper surface of the support platform 15. An adjustment member 16 that can adjust the distance between the two vertical plates 23 is provided on the support platform 15.

[0061] The adjusting component 16 includes an adjusting screw 161 rotatably mounted on the support platform 15 and an adjusting block 162 fixed on the bottom side of the vertical plate 23. The adjusting block 162 is slidably mounted on the upper side of the support platform 15, and the two adjusting blocks 162 can slide back and forth along the length of the adjusting screw 161.

[0062] A handwheel 163 is fixed at one end of the adjusting screw 161. The outer circumferences of the two ends of the adjusting screw 161 are respectively formed with threads in opposite directions. The two adjusting blocks 162 are provided with adjusting screw holes (not shown in the figure) for the adjusting screw 161 to be screwed in and pass through. The operator can drive the adjusting screw 161 to rotate by the handwheel 163, which can then drive the two adjusting blocks 162 to slide towards and away from each other, thereby adjusting the distance between the two vertical plates 23.

[0063] Reference Figure 8 The limiting member 26 includes a limiting rod 261 that slides on the inner walls of the two vertical plates 23 close to each other. The installation direction of the limiting rod 261 is perpendicular to the upper surface of the lifting plate 241, and the sliding direction is parallel to the upper surface of the lifting plate 241. The outside of the vertical plate 23 is provided with a locking member 262 to fix the sliding state of the limiting rod 261. The locking member 262 is a similar butterfly bolt fastening structure, which will not be described in detail here.

[0064] Reference Figure 9 The fixing block 224 can slide back and forth along the length of the crossbar 222, and the pressing part 225 has a limiting notch 2251 on the side facing the base 1 for the upper edge of the vertical plate 23 to be inserted; and when the pressing part 225 rotates, the upper edge of the vertical plate 23 rotates synchronously relative to the limiting notch 2251, that is, the opening of the limiting notch 2251 will not interfere with the rotation of the clamping suction cup 226;

[0065] When the distance between the two vertical plates 23 is adjusted synchronously, the upper edge of the vertical plate 23 is always inserted into the corresponding limiting notch 2251, so that the distance between the two fixed plates is adjusted synchronously; this can not only enhance the installation stability between the two vertical plates 23, but also slide and fix the fixed plates.

[0066] Reference Figure 9 and Figure 10 A limiting gap is provided between the barrier plate 25 and the vertical plate 23. A pressing rod 27 is rotatably mounted on the barrier plate 25 within the limiting gap. The pressing rod 27 is used to limit the side edge of the uppermost packaging bag near the barrier plate 25. A proximity switch 28 is fixed on the barrier plate 25 below the pressing rod 27 and can control the operation of the first power component 223. After the clamping suction cup 226 clamps the uppermost packaging bag, the pressing rod 27 rotates downward and abuts against the upper surface of the proximity switch 28. When the lifting plate 241 moves upward, the pressing rod 27 can rotate upward and separate from the upper surface of the proximity switch 28.

[0067] The lifting plate 241 moves upward, causing the topmost packaging bag to rise, which in turn pushes the pressing rod 27 to rotate upward and separate from the proximity switch 28. At this time, the proximity switch 28 detects the signal change and immediately controls the first power component 223 to operate, so that the clamping suction cup 226 can clamp the topmost packaging bag in time. After clamping, the pressing rod 27 rotates downward under its own gravity and abuts against the proximity switch 28 again, preparing for the next cycle. The lifting plate 241 continues to move upward, pushing the subsequent packaging bags to rise, and so on.

[0068] Reference Figure 11 The bag opening assembly 3 includes a vertical rod 31 fixed on the base 1 and a support plate 32 fixed on the upper part of the vertical rod 31. An extension plate 321 is fixed on one vertical surface of the support plate 32. Two suction cup frames 33 are arranged opposite each other below the extension plate 321. A negative pressure suction cup 331 is fixed on the side of the two suction cup frames 33 that are close to each other. The extension plate 321 is provided with a first driving source 34 that drives the two suction cup frames 33 to slide back and forth in the direction of closeness. The first driving source 34 is a structure similar to a pneumatic finger, which will not be described in detail here.

[0069] A fixed rod 35 is slidably provided on the side of the support plate 32 away from the vertical rod 31, and a second power component 36 is installed to drive the fixed rod 35 to slide up and down. The second power component 36 is a combination structure of a motor and a cam-like structure, which will not be described in detail here. The length direction of the fixed rod 35 is perpendicular to the axis of the vertical rod 31, and the sliding direction is parallel to the axis of the vertical rod 31. A bag opening component 37 is provided on the fixed rod 35 between the two suction cup frames 33.

[0070] Reference Figure 12 The bag opening component 37 includes two inner clamping rods 371 that are rotatably mounted on the fixed rod 35, and a first power source 372 that drives the two inner clamping rods 371 to rotate towards and away from each other. The two inner clamping rods 371 are both located between the two suction cup frames 33. A vertically downward outer clamping rod 373 is rotatably mounted on the opposite sides of the two inner clamping rods 371, and a second power source 374 is provided on the inner clamping rods 371 to drive the outer clamping rods 373 to reciprocate towards the inner clamping rods 371.

[0071] Reference Figure 12 and Figure 13 The first power source 372 includes a linkage 3721, a first cylinder 3722, and a first connecting rod 3723 coaxially and fixedly connected to the hydraulic rod of the first cylinder 3722. A first protrusion 351 is fixedly provided on the lower side of the fixed rod 35, and the side of the first cylinder 3722 away from the first connecting rod 3723 is rotatably connected to the first protrusion 351.

[0072] The upper ends of the two inner clamping rods 371 are rotatably connected to the fixed rod 35. The end of the first connecting rod 3723 away from the first cylinder 3722 is rotatably connected to the middle part of one of the two inner clamping rods 371 away from the vertical rod 31. The linkage 3721 is specifically a linkage rod 37211, which is used to connect the two inner clamping rods 371. The two ends of the linkage rod 37211 are rotatably connected to the upper parts of the two inner clamping rods 371 respectively. When the inner clamping rod 371 away from the vertical rod 31 rotates, the inner clamping rod 371 close to the vertical rod 31 is driven to rotate through the linkage 3721.

[0073] Reference Figure 12 and Figure 13 The second power source 374 includes a second cylinder 3741 and a second connecting rod 3742 coaxially fixed with the hydraulic rod of the second cylinder 3741. The outer clamping rod 373 has an integrally formed protrusion 3731 on the side away from the inner clamping rod 371. The protrusion 3731 is rotatably connected to the end of the second connecting rod 3742 away from the second cylinder 3741. The side of the second cylinder 3741 away from the second connecting rod 3742 is rotatably connected to the inner clamping rod 371.

[0074] Reference Figure 14 An arc-shaped plate 17 is installed above the base 1. The heat sealing assembly 4 includes a first heat sealing element 41 and a second heat sealing element 42 fixed on the arc-shaped plate 17. The first heat sealing element 41 is located on the side closer to the filling assembly 13, and the second heat sealing element 42 is located on the side closer to the upper bag assembly 2. Both the first heat sealing element 41 and the second heat sealing element 42 include a heat sealing strip disposed above the base 1 and a cylinder for driving the heat sealing strip to move. This is a conventional heat sealing structure. In addition, the filling assembly 13 is also a conventional structure. Both will not be described in detail here.

[0075] During heat sealing, the packaging bag undergoes heat sealing treatment sequentially through a first heat sealer 41 and a second heat sealer 42. The first heat sealer 41 acts on the packaging bag before the second heat sealer 42, and the heat sealing temperature of the first heat sealer 41 is higher than that of the second heat sealer 42. This double heat sealing process not only improves the heat seal strength but also allows for a rapid reduction in the temperature of the bag opening during the second heat sealing, thus decreasing the probability of deformation.

[0076] The discharge assembly 5 includes a guide plate 51 located below the second heat sealer 42 and a conveyor belt 52 fixed on the base 1. The conveyor belt 52 is driven by a common motor, and its specific structure will not be described in detail here. The lower edge of the guide plate 51 is fixed to the upper side edge of the conveyor belt 52 near the rotating disk 11, and the guide plate 51 is inclined upward along the direction near the rotating disk 11.

[0077] Reference Figure 14 and Figure 15The base 1 is fixedly provided with a first column 18 near the upper bag assembly 2 and a second column 19 near the filling assembly 13. The bottom surfaces of both ends of the arc plate 17 are fixedly connected to the upper parts of the first column 18 and the second column 19, respectively. The clamping component 21 includes a clamping claw 211 for clamping the packaging bag on the clamping suction cup 226 and a third power source 212 installed in the first column 18. The clamping claw 211 is a conventional clamping structure driven by a small cylinder, which will not be described in detail here.

[0078] The third power source 212 is a small motor installed inside the first column 18, and a conveying shaft 2121 extending to the outside of the first column 18 is fixed on the third power source 212. The third power source 212 is used to drive the clamping claw 211 to rotate around the conveying shaft 2121. The clamping claw 211 can rotate from the vertical plate 23 toward the clamping member 12 on the rotating disk 11.

[0079] The implementation principle of this application embodiment is as follows:

[0080] The pre-stacked packaging bags are placed between the two vertical plates 23 of the upper bag assembly 2, and the lifting member 24 supports the packaging bags. After the proximity switch 28 detects that the packaging bags are in place, it controls the operation of the power component. The gripping suction cup 226 of the gripping member 22 first rotates around the output shaft 2231, and then rotates around the connecting shaft 22141 to fully press and grip the uppermost packaging bag. At the same time, the pressing part 225 presses the packaging bag to make it bend. The clamping member 21 clamps the packaging bag gripped by the gripping suction cup 226 onto the clamping member 12 of the rotating disk 11.

[0081] The rotating disk 11 drives the packaging bag to pass through the bag opening component 3 in sequence. The suction cup frame 33 and the inner and outer clamping rods 373 work together to open the bag mouth. The material injection component 13 injects the material into the packaging bag. Then it reaches the heat sealing component 4, where the first and second heat sealing parts 42 seal the bag mouth. Finally, the guide plate 51 of the discharge component 5 guides the packaged packaging bag to the conveyor belt 52 and removes it, completing the entire packaging process. This cycle is repeated to achieve fully automatic bag feeding and packaging.
