Description

Technical Field

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

[0002] With the booming health food market, a wide variety of snack products are gaining popularity among consumers. As consumers' pursuit of a higher quality of life continues to improve, they are placing increasingly diverse demands on food packaging. They not only expect packaging to effectively guarantee product freshness and safety, but also increasingly prioritize ease of use and visual aesthetics. As a crucial piece of equipment in the food packaging industry, optimizing the performance of bagging machines is crucial to meeting market demands and improving packaging efficiency.

[0003] Currently, a common bag-feeding packaging machine primarily consists of a base, a rotating sleeve, and a rotating disc. The rotating sleeve is rotatably mounted on the base, while the rotating disc is fixed to the upper end of the rotating sleeve. A drive assembly within the base drives the rotating sleeve. The rotating disc houses a clamping assembly for holding the bags. Components for bag placement, bag opening, filling, sealing, and discharging are arranged around the base. The bag placement assembly includes a feed conveyor belt and a negative pressure suction cup. The feed conveyor belt is tilted downward to stack the bags. The negative pressure suction cup, driven by a pneumatic cylinder, moves up and down to hold the topmost bag.

[0004] However, problems arise when feeding larger, softer bags. Due to static electricity, when using a negative pressure suction cup to clamp a bag on the upper side of the feed spout, another bag on the bottom side may be tightly attached to it, resulting in two bags being clamped simultaneously. However, the subsequent clamping components can only clamp bags one by one and cannot handle two bags. At the same time, bags adsorbed by static electricity may fall off during the clamping process, causing the tightly arranged bags on the feed conveyor belt to become scattered, affecting subsequent clamping. Both situations require manual intervention and sorting, which seriously affects packaging efficiency and leaves 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 packaging bags with a large area and soft material, two packaging bags may be clamped at the same time due to the effect of static electricity, which requires manual intervention and sorting, and ultimately affects the overall packaging efficiency.

[0006] The fully automatic bag-feeding and packaging machine provided in this application adopts the following technical solutions: A fully automatic bag feeding and packaging machine comprises a base, a rotating disk rotatably mounted on the upper surface of the base, and a driving member that drives the rotating disk to operate; a plurality of clamping members for clamping the packaging bags are arranged on the outer circumference of the rotating disk; a bag loading assembly, a bag opening assembly, a material injection assembly, a heat sealing assembly and a material discharge assembly are sequentially arranged on the base around the rotating disk; the bag loading assembly comprises a clamping member, two vertical plates fixed side by side on the upper surface of the base, and a lifting member that can move up and down between the two vertical plates; a blocking plate is fixed on the vertical sides of the same side of the two vertical plates, and a limiting member is provided on the vertical side away from the blocking plate, and the lifting member is inclined downward in the direction close to the blocking plate and can support The packaging bags are stacked between the two vertical plates; the clamping member includes a connecting member, a horizontal bar located above the vertical plate, and a first power member installed on the base, the horizontal bar is fixed with a fixed block located between the two vertical plates, and the fixed block is fixed with a clamping suction cup and a pressing part; the first power member is fixed with an output shaft, and the first power member drives the fixed block to rotate around the output shaft through the connecting member, when the fixed block rotates downward, the clamping suction cup clamps the top packaging bag, and when it rotates upward, the pressing part presses the upper side of the packaging bag to bend it; the base is provided with a clamping member for clamping the packaging bag clamped by the clamping suction cup to the clamping member.

[0007] By adopting this technical solution, the lifting member in the bag-loading assembly tilts and supports the stacked bags. When the gripping member's suction cup grasps the top bag, the pressing portion bends the bag's upper side, reducing static electricity that can cause two bags to be clamped simultaneously. It also prevents bags from falling off during the gripping process, causing the stack to become disorganized. This design eliminates the need for manual intervention and significantly improves packaging efficiency, meeting market demand for efficient and stable packaging equipment.

[0008] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is, for example, that of an automobile sprocket, an older boy is mounted on a motorcycle, and the motorcycle is’s motorcycle.

[0009] By adopting the above technical solution, the connecting member, through the coordinated cooperation of the connecting plate, transmission rod, connecting rod, and extrusion rod, utilizes the elastic member to drive the extrusion rod to rotate downward. Combined with the tight contact between the limiting wheel and the limiting convex plate, the first power member can simultaneously drive the extrusion rod and crossbar to rotate around the output shaft and, under certain conditions, also drive the crossbar to rotate around the connecting shaft. This composite motion method allows the gripping suction cup and pressing part of the gripping member to more accurately and flexibly complete the gripping and pressing actions of the packaging bag, effectively reducing gripping anomalies 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 feeding packaging machine.

[0010] Optionally, a limiting gap is provided between the blocking plate and the vertical plate, and a pressing rod located in the limiting gap is rotatably mounted on the blocking plate, and the pressing rod is used to limit the side edge of the top packaging bag close to the blocking plate; a proximity switch is fixed on the blocking plate and is located below the pressing rod, which can control the operation of the first power part. After the clamping suction cup clamps the top packaging bag, the pressing rod rotates downward and abuts against the upper surface of the proximity switch. When the pressing rod moves up on the lifting plate, it can rotate upward and separate from the upper surface of the proximity switch.

[0011] By adopting this technical solution, the proximity switch on the barrier plate is cleverly positioned. When the gripping suction cup grabs the top bag, the pressing rod rotates downward to contact the proximity switch, controlling the first power element and achieving automated operation. When the lifting plate moves upward, the pressing rod rotates upward to disengage the proximity switch, allowing all components to operate in an orderly manner. This design effectively improves the packaging machine's automation level and operating accuracy, reduces manual intervention, and ensures packaging efficiency and quality.

[0012] 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 capable of adjusting the distance between the two vertical plates is provided on the support platform.

[0013] By adopting this 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 a good stacking state 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 stability of the structure. The installation of an adjustment member that can adjust the spacing between the two vertical plates can flexibly adjust the spacing between the two vertical plates according to the different sizes of packaging bags, making the packaging machine more versatile and adaptable, and able to meet the packaging needs of various specifications of packaging bags without the need for frequent replacement of equipment components, effectively reducing production costs and improving the efficiency and flexibility of the packaging machine.

[0014] Optionally, the fixed block can slide back and forth along the length direction of the cross bar, and a limiting notch is provided on the side of the pressing portion facing the base for inserting the upper edge of the vertical plate. When the pressing portion rotates, the upper edge of the vertical plate rotates synchronously relative to the limiting notch.

[0015] By adopting this technical solution, the fixed block can slide back and forth along the length of the crossbar, allowing the position of the clamping suction cup and the pressing portion to be flexibly adjusted, better accommodating packaging bags of varying sizes and stacking conditions, and improving the accuracy of clamping and pressing. The pressing portion has a retaining notch on the side facing the base for the upper edge of the riser to insert into. As the pressing portion rotates, the upper edge of the riser rotates synchronously with the retaining notch relative to the retaining notch. This coordination further enhances the stability of the pressing portion's pressure on the packaging bag.

[0016] Optionally, the limiting member includes a limiting rod slidably arranged 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 member is provided on the outside of the vertical plate to fix the sliding state of the limiting rod.

[0017] By adopting the above technical solution, this arrangement can flexibly adjust the position of the limit rod to meet the stacking requirements of bags of different widths, effectively limiting the bags and preventing them from scattering. The locking member provided on the exterior of the vertical plate can fix the sliding state of the limit rod, ensuring that the limit rod remains stable after being adjusted to the appropriate position. This prevents the limit rod from moving during the packaging process and affecting the stacking and clamping of bags, thus ensuring the stable and efficient operation of the fully automatic bag feeding and packaging machine.

[0018] Optionally, the bag opening assembly includes a vertical rod fixed on the base, a support plate fixed vertically on the upper part of the vertical rod, an extension plate fixed on a vertical surface of one side of the support plate, two suction cup frames are relatively arranged below the extension plate, and negative pressure suction cups are fixed on the sides of the two suction cup frames close to each other, and a first driving source is provided on the extension plate to drive the two suction cup frames to slide back and forth in the direction of approaching each other; a fixed rod is provided on the side of the support plate away from the vertical rod, and a second power part 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; the fixed rod is provided with a bag opening component located between the two suction cup frames.

[0019] By adopting this technical solution, the vertical rods, support plate, and other components form a stable frame. Two opposing suction cups and negative pressure cups, positioned beneath the extension plate, are driven by a first drive source to slide back and forth toward each other, precisely adhering to both sides of the bag and opening it. Furthermore, a slidable fixed rod on the support plate and a second power element driving its movement, combined with a bag opening element located between the two suction cups on the fixed rod, further assist in opening the bag after adsorption, ensuring it is fully opened.

[0020] Optionally, the bag opening part includes two inner clamping rods arranged on a fixed rod for relative rotation, and a first power source for driving the two inner clamping rods to rotate toward and away from each other, and the two inner clamping rods are located between two suction cup frames; an outer clamping rod is rotatably installed vertically downward on the opposite sides of the two inner clamping rods, and a second power source is provided on the inner clamping rod to drive the outer clamping rod to rotate back and forth toward the inner clamping rod.

[0021] By adopting this technical solution, two inner clamping rods are mounted on a fixed rod and rotate relative to each other. Driven by a first power source, they rotate toward and away from each other. Positioned between the two suction cup frames, they further assist in opening the bag opening, ensuring a more effective bag opening. Simultaneously, a vertically downward outer clamping rod, mounted on opposite sides of the inner clamping rods, rotates back and forth toward the inner clamping rods under the action of a second power source, better gripping the bag and enhancing bag opening stability. This design makes the bag opening process more precise and reliable, effectively improving the efficiency and success rate of the bag opening process in the fully automatic bag-feeding packaging machine, and ensuring the smooth progress of subsequent packaging processes.

[0022] Optionally, an arc-shaped plate is installed above the base, and the heat sealing assembly includes a first heat sealing part and a second heat sealing part fixed on the arc plate, the first heat sealing part is close to the side of the injection assembly, and the second heat sealing part is located on the side close to the upper bag assembly; the discharge assembly includes a guide plate located below the second heat sealing part 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 close to the rotating disk, and the guide plate is arranged to be inclined upward in the direction close to the rotating disk.

[0023] By adopting the above technical solution, a first and second heat-sealing element are arranged on the curved plate, adjacent to the injection assembly and bagging assembly, respectively. This rational layout enables heat-sealing operations at different stages of the packaging bag. During heat sealing, the packaging bag passes through the first and second heat-sealing elements sequentially, with the first heat-sealing element acting on the packaging bag before 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. This double heat-sealing of the packaging bag not only improves the heat seal strength but also rapidly reduces the temperature of the bag opening during the second heat-sealing process, thereby reducing the probability of deformation. In the discharge assembly, a guide plate positioned below the second heat-sealing element is tilted upward, with its lower edge fixed to the upper side edge of the conveyor belt near the rotating disk. This structure allows the sealed bags to slide smoothly through the guide plate onto the conveyor belt, achieving orderly discharge and preventing bags from scattering or accumulating. This ensures an efficient and continuous packaging process for the entire fully automatic bag-feeding packaging machine, improving production efficiency and packaging quality.

[0024] Optionally, a first column close to the upper bag assembly and a second column close to the injection assembly are fixed on the base, and the bottom surfaces at both ends of the arc plate are fixedly connected to the upper parts of the first column and the second column respectively; the clamping part includes a clamping claw for clamping the packaging bag on the clamping suction cup and a third power source installed in the first column; the third power source is fixed with a conveying shaft extending to the outside of the first column, and the third power source is used to drive the clamping claw to rotate around the conveying shaft, and the clamping claw can rotate from the upper side of the vertical plate to the direction of the clamping part on the rotating disk.

[0025] By adopting this technical solution, a first column and a second column are respectively installed on the base near the bag opening assembly and the injection assembly, and the bottom surfaces of the curved plates at both ends are fixedly connected to them, providing stable support for the heat sealing assembly and ensuring stable heat sealing operation. The clamping parts are cleverly designed. The clamping claws rotate around the conveyor shaft driven by a third power source. They can flexibly rotate from the upper part of the vertical plate toward the clamping parts on the rotating disk, accurately grasping the packaging bag on the clamping suction cup, and realizing smooth transfer of packaging bags between various components. This improves the automation level and operational smoothness of the fully automatic bag feeding and packaging machine, effectively improving packaging efficiency and quality.

[0026] In summary, this application has the following beneficial technical effects: During operation, the lifting element in the bag-feeding packaging machine tilts and supports the stacked bags. When the gripper's suction cup grasps the top bag, the pressing portion bends the bag's upper side, reducing static electricity that can cause two bags to be clamped simultaneously. It also prevents bags from falling during the gripping process and causing the stack to become disorganized. This design eliminates the need for manual intervention and significantly improves packaging efficiency, meeting market demand for efficient and stable packaging equipment.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] Example: Reference Figure 1 A fully automatic bag-feeding packaging machine includes a base 1, a rotating disk 11 rotatably mounted on the upper surface of the base 1, and a driving member (not shown in the figure) that drives the rotating disk 11.

The clamping member 12 is mainly used to clamp the two opposite edges of the packaging bag opening. The specific structures of the driving member and the clamping member 12 are not repeated here. The pre-stacked packaging bags are automatically loaded onto the clamping parts 12 on the rotating disk 11 through the bag loading assembly 2, and then the rotating disk 11 drives the clamping parts 12 holding the packaging bags to rotate.

[0034] Reference Figure 4 and Figure 5 The clamping member 22 includes a connecting member 221, a cross bar 222 located above the vertical plate 23, and a first power member 223 installed on the base 1. A fixed block 224 located between the two vertical plates 23 is fixed on the cross bar 222, and a clamping suction cup 226 and a pressing portion 225 are fixed on the fixed block 224; an output shaft 2231 is fixed on the first power member 223, and the first power member 223 drives the fixed block 224 to rotate around the output shaft 2231 through the connecting member 221.

The axes of the crossbar 222, the output shaft 2231, and the connecting shaft 22141 are parallel to each other. The rotation of the clamping suction cup 226 is divided into two steps: the first step is that the first power member 223 drives the extrusion rod 2214, the connecting rod 2213, the connecting plate 2211 and the cross bar 222 to rotate around the axis of the output shaft 2231. At this time, the limiting wheel 22142 has not yet abutted against the upper surface of the limiting convex plate 141; the second step, the output shaft 2231 continues to drive the transmission rod 2212 and the connecting rod 2213 to rotate downward. At this time, the connecting plate 2211 cannot continue to rotate around the output shaft 2231, but the connecting plate 2211 can rotate around the axis of the connecting shaft 22141, further driving the clamping suction cup 226 to rotate, so that the clamping suction cup 226 can fully abut against the topmost packaging bag for clamping.

A locking member 262 is provided on the outside of the vertical plate 23 to fix the sliding state of the limiting rod 261. The locking member 262 is a similar butterfly bolt fastening structure and will not be repeated here.

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; The lifting plate 241 moves upward to drive the top packaging bag to rise, and then 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 part 223 to operate, so that the clamping suction cup 226 can clamp the top packaging bag in time; after the clamping is completed, the pressing rod 27 rotates downward under the action of its own gravity and abuts against the proximity switch 28 again, preparing for the next cycle. The lifting plate 241 continues to move upward to push the subsequent packaging bags to rise, and this cycle repeats.

In addition, the injection assembly 13 is also a conventional structure, and the two are not described in detail here; When heat-sealing the bag, it passes through the first heat-sealing element 41 and the second heat-sealing element 42 in sequence. The first heat-sealing element 41 acts on the bag before the second heat-sealing element 42, and the heat-sealing temperature of the first heat-sealing element 41 is higher than that of the second heat-sealing element 42. Heat-sealing the bag twice not only improves the heat seal strength, but also quickly reduces the temperature of the bag opening during the second heat-sealing process, reducing the possibility of deformation.

The clamping claw 211 can rotate from the upper part of the vertical plate 23 toward the clamping member 12 on the rotating disk 11.

[0045] The implementation principle of the embodiment of this application is: The pre-stacked bags are placed between the two vertical plates 23 of the upper bag assembly 2, supported by the lifting member 24. When the proximity switch 28 detects the bags are in place, it controls the power member 22 to operate. The gripping suction cup 226 of the gripping member 22 first rotates around the output shaft 2231, then around the connecting shaft 22141, fully pressing against and gripping the topmost bag. Simultaneously, the pressing portion 225 presses the bag, causing it to bend. The clamping member 21 then clamps the bag held by the gripping suction cup 226 onto the clamping member 12 of the rotating disk 11. The rotating disk 11 drives the packaging bag to pass through the bag opening assembly 3 in sequence, and the bag opening is opened by the suction cup frame 33 and the inner and outer clamping rods 373; the injection assembly 13 injects the material into the packaging bag; then it reaches the heat sealing assembly 4, and the bag opening is sealed by the first and second heat sealing members 42; finally, the guide plate 51 of the discharge assembly 5 guides the packaged packaging bag to the conveyor belt 52 for removal, completing the entire packaging process. This cycle is repeated to achieve fully automatic bag feeding and packaging.
