Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to a feeding mechanism and a packaging machine. Background Technology

[0002] Currently, packaged goods of various sizes have become ubiquitous in households, making it a significant industry influencing people's lives. Among the production equipment for bagged packaging, pre-packaging machines are a common type of packaging equipment.

[0003] Existing bag-feeding packaging machines, especially those for wide-width bags, require a dedicated feeding mechanism to remove the bags from the bag magazine and transfer them to the bag-grabbing position on the packaging machine due to the large bag width. The existing feeding mechanism consists of a horizontally moving guide rail and a vertically moving cylinder, forming an XY dual-axis motion that drives the bag-grabbing bracket and suction cups to remove the bags from the bag magazine and transfer them to the bag-grabbing position on the packaging machine. Because the bag-grabbing bracket has a certain mass, it requires multiple accelerations and decelerations during vertical and horizontal movements, resulting in a long process time and low efficiency. Furthermore, the presence of sliding and fixed guide rails, as well as transmission components, places certain demands on the structure and precision, leading to high maintenance costs and making it unsuitable for use in corrosive environments. Utility Model Content

[0027] Please combine them together Figures 1 to 5 The feeding mechanism provided by this utility model will now be described. The feeding mechanism is used in packaging machines.

[0028] The feeding mechanism includes a machine body 1 and a conveying component 2. The machine body 1 has a bag bin 11 and a positioning bin 12. The conveying component 2 is installed on the machine body 1 and is used to absorb and feed the material in the bag bin 11 to the positioning bin 12. Specifically, the packaging bag is placed in the bag bin 11 manually, and the conveying component 2 can absorb and transport the packaging bag in the bag bin 11 to the positioning bin 12, which is the gripping position of the packaging machine. The packaging machine then grips and packages the packaging bag in the positioning bin 12.

[0029] The conveying assembly 2 includes a first drive module 21, a second drive module 22, a first transmission link 23, a second transmission link 24, a boom 25, a forearm 26, and a conveying module 27. The first drive module 21 is fixed inside the body 1. The first transmission link 23 is rotatably connected to the body 1 and fixed to the boom 25. The first drive module 21 is connected to the first transmission link 23 and is used to drive the first transmission link 23 to reciprocate the boom 25. The second drive module 22 is fixed to the boom 25. The first transmission link 23 is hollow inside. The second transmission link 24 is disposed inside the hollow and is rotatably connected to the boom 25. The second drive module 22 is connected to the forearm 26 through the second transmission link 24 and is used to drive the second transmission link 24 to reciprocate the forearm 26. The conveying module 27 is installed on the forearm 26.

[0030] It is understood that the conveying component 2 of the feeding mechanism is installed on the machine body 1 and is used to absorb and feed the material in the bag hopper 11 to the positioning hopper 12. The first drive module 21 is fixed inside the machine body 1, and the first transmission link 23 is rotatably connected to the machine body 1 and fixed to the upper arm 25. The first drive module 21 is drive-connected to the first transmission link 23 and is used to drive the first transmission link 23 to reciprocate the upper arm 25. The second drive module 22 is fixed to the upper arm 25. The first transmission link 23 is hollow inside, and the second transmission link 24 is disposed inside the hollow and rotatably connected to the upper arm 25. The second drive module 22 is drive-connected to the lower arm 26 through the second transmission link 24 and is used to drive the second transmission link 24 to reciprocate the lower arm 26. The conveying module 27 is installed on the lower arm 25. Arm 26, thus, the first drive module 21 drives the first transmission link 23 to drive the upper arm 25 to swing back and forth. The upper arm 25 drives the second drive module 22, the second transmission link 24, the lower arm 26 and the conveying module 27 to move back and forth. At the same time, the second drive module 22 drives the second transmission link 24 to drive the lower arm 26 to swing back and forth. The lower arm 26 drives the conveying module 27 to swing back and forth, thus forming a coaxial double swing arm mode. The upper arm 25 and the lower arm 26 combine different angles and drive the conveying module 27 to transport the material from the bag bin 11 to the positioning bin 12, that is, to the bag gripping position of the packaging machine. Because there are no sliding parts, the transmission efficiency is high and the speed is fast. The first transmission link 23 and the second transmission link are located at the bottom of the machine body 1, which is small in size, easy to maintain, and can be used in corrosive environments.

[0031] In this embodiment, the first drive module 21 includes a first drive motor 211, a first sprocket 212, a chain 213, and a second sprocket 214. The output shaft of the first drive motor 211 is fixed to the first sprocket 212, and the second sprocket 214 is fixed to the first transmission link 23. The chain 213 surrounds the first sprocket 212 and the second sprocket 214. Specifically, the first drive motor 211 drives the first sprocket 212 to rotate, the first sprocket 212 drives the chain 213 to move, the chain 213 drives the second sprocket 214 to rotate, the second sprocket 214 drives the first transmission link 23 to rotate, the first transmission link 23 drives the upper arm 25 to swing back and forth, and the upper arm 25 drives the second drive module 22, the second transmission link 24, the lower arm 26, and the transport module 27 to swing back and forth.

[0032] Furthermore, the second drive module 22 includes a second drive motor 221, a commutator 222, a first synchronous pulley, a synchronous belt 223, and a second synchronous pulley 224. The commutator 222 is fixed to the upper arm 25, and the second drive motor 221 is connected to the commutator 222 in a transmission connection. The first synchronous pulley is fixed to the second transmission link 24, and the rotation shaft of the second synchronous pulley 224 is rotatably connected to the upper arm 25. The rotation shaft of the second synchronous pulley 224 is also fixed to the lower arm 26. The synchronous belt 223 surrounds the first synchronous pulley and the second synchronous pulley 224. Specifically, the first drive motor 211 drives the first sprocket 212 to rotate, the first sprocket 212 drives the chain 213 to move, the chain 213 drives the second sprocket 214 to rotate, the second sprocket 214 drives the first transmission link 23 to rotate, the first transmission link 23 drives the upper arm 25 to swing back and forth, and the upper arm 25 drives the second drive module 22, the second transmission link 24, the lower arm 26, and the transport module 27 to swing back and forth. At the same time, the second drive motor 221 drives the commutator 222 to rotate the second transmission link 24, the second transmission link 24 drives the first synchronous pulley to rotate (not shown in the figure), the first synchronous pulley drives the synchronous belt 223 to move, the synchronous belt 223 drives the second synchronous pulley 224 to rotate, the rotation shaft of the second synchronous pulley 224 drives the forearm 26 to swing back and forth, and the forearm 26 then drives the conveying module 27 to swing back and forth.

[0033] Furthermore, the transport assembly 2 also includes a first swing angle link 28, a first swing angle bracket 29, a second swing angle link 291, and a second swing angle bracket 292. The first swing angle bracket 29 is rotatably connected to the rotating shaft of the second synchronous pulley 224. One end of the first swing angle link 28 is rotatably connected to the machine body 1, and the other end is rotatably connected to one end of the first swing angle bracket 29. One end of the second swing angle link 291 is rotatably connected to the other end of the first swing angle bracket 29, and the other end is rotatably connected to one end of the second swing angle bracket 292. The other end of the second swing angle bracket 292 is rotatably connected to the forearm 26. Specifically, the first swing angle bracket 29 is V-shaped. The first swing angle link 28, the machine body 1, the upper arm 25, and the first swing angle bracket 29 form a parallelogram structure. When the upper arm 25 swings, the first swing angle bracket 29 and the machine body 1 always maintain a certain angle. The first swing bracket 29, the second swing link 291, the second swing bracket 292, and the forearm 26 form a parallelogram structure. When the forearm 26 swings, the first swing bracket 29 and the second swing bracket 292 always maintain a certain angle. Because the upper arm 25, the forearm 26, the first swing link 28, the second swing link 291, the first swing bracket 29, and the second swing bracket 292 maintain an interconnected parallelogram structure, regardless of the combined angle of the upper arm 25 and the forearm 26, the conveying module 27 always maintains a certain angle with the body 1, allowing the conveying module 27 to face the packaging bag and thus adsorb the packaging bag.

[0034] Furthermore, the transport module 27 includes a rotating shaft 271, a bracket 272, a mounting plate 273, and a suction cup 274. The suction cup 274 is mounted on the bracket 271 via the mounting plate 273, and the bracket 271 is fixed to the other end of the second swing angle bracket 292 via the rotating shaft 271. Specifically, when the upper arm 25 and the lower arm 26 swing, the first swing angle connecting rod 28, the first swing angle bracket 29, the second swing angle connecting rod 291, and the second swing angle bracket 292 move. The second swing angle bracket 292 drives the rotating shaft 271 to rotate, and the rotating shaft 271 drives the bracket 272, the mounting plate 273, and the suction cup 274 to rotate, so that the suction cup 274 is always kept at a certain angle with the body 1.

[0035] The above structure allows the suction cup to move at any position within a designated area above the bag compartment 11 and the positioning compartment 12, while maintaining a constant direction.

[0036] Furthermore, the bracket is provided with a slide groove 2721, and the mounting plate 273 is slidably connected to the slide groove 2721. In this way, the mounting plate 273 can move to an appropriate position within the slide groove 2721, thereby adjusting the position of the suction cup to accommodate packaging bags of different sizes.

[0037] Furthermore, the transport module 27 also includes a vacuum generator 275, which is fixed to the body 1 and connected to the suction cup. This allows the suction cup to create a vacuum, thereby adsorbing the packaging bag.

[0038] In one embodiment, such as Figure 1 As shown, the feeding mechanism also includes a first side baffle 3, a second side baffle 4, and a tail baffle 5. These three baffles form a bag compartment 11, and are slidably connected to the adjustment groove 13 of the machine body 1. When a packaging bag is placed in the bag compartment 11, the first side baffle 3, the second side baffle 4, and the tail baffle 5 can slide within the adjustment groove 13 of the machine body 1, thereby adjusting the size of the bag compartment 11 to accommodate packaging bags of different widths and lengths. After adjustment to the appropriate position, the locking mechanism is tightened.

[0039] like Figure 1 and Figure 4As shown, the feeding mechanism also includes a lead screw 6, a lead screw nut 7, a first cylinder 8, a first bag clamping plate 9, a second bag clamping plate 91, a second cylinder 92, a bag pushing bottom plate 93, a bag pushing plate 94, a third cylinder 95, and a stop plate 96. The first bag clamping plate 9, the second bag clamping plate 91, the bag pushing plate 94, and the stop plate 96 surround to form a positioning chamber 12. The lead screw 6 is rotatably connected to the machine body 1. The lead screw 6 has two threads, and the two threads rotate in opposite directions. There are two lead screw nuts 7, which are threadedly connected to the two threads respectively. There are two first cylinders 8, which are fixed to the two threads respectively. The nut 7 and the telescopic rods of the two first cylinders 8 are respectively fixed to the first bag clamping plate 9 and the second bag clamping plate 91, and are used to drive the first bag clamping plate 9 and the second bag clamping plate 91 to move closer or further apart. The second cylinder 92 is fixed to the machine body 1. The telescopic rod of the second cylinder 92 is fixed to the push bag plate 94 through the push bag bottom plate 93, and is used to drive the push bag bottom plate 93 to push the push bag plate 94 out and retract. The third cylinder 95 is fixed to the machine body 1. The telescopic rod of the third cylinder 95 is fixed to the stop plate 96, and is used to drive the stop plate 96 out and retract.

[0040] Specifically, rotating the lead screw 6 causes the two oppositely helical threads on the lead screw 6 to move the lead screw nut 7, which in turn moves the first cylinder 8. The first cylinder 8 then moves the first bag clamping plate 9 and the second bag clamping plate 91 closer together or further apart, thereby adjusting the width between the first bag clamping plate 9 and the second bag clamping plate 91 to accommodate packaging bags of different widths. After the packaging bag adsorbed by the suction cup is moved to the positioning chamber 12, the first cylinder 8 drives the first bag clamping plate 9 and the second bag clamping plate 91 to move closer together along the linear bearing to define the centerline and angle of the packaging bag. Next, the third cylinder 95 drives the stop plate 96 to push out to define the front end direction of the packaging bag. Then, the second cylinder 92 drives the pusher plate 93 and the pusher plate 94 to move along the linear bearing to press the packaging bag against the stop plate 96, thereby defining the front-back direction of the packaging bag.

[0041] The body 1 is provided with multiple clearance slots 14, each clearance slot 14 being used to avoid the movement of the first bag clamping plate 9, the second bag clamping plate 91, and the bag pushing plate 94. By setting the clearance slots 14, interference will not occur during the movement of the first bag clamping plate 9, the second bag clamping plate 91, and the bag pushing plate 94.

[0042] The pusher plate 94 is slidably connected to the pusher base plate 93. This allows the pusher plate 94 to be positioned at different locations on the pusher base plate 93 to accommodate packaging bags of different lengths. After adjusting to the appropriate position, the locking mechanism is tightened.

[0043] This utility model also provides a packaging machine, which includes the feeding mechanism of any of the above embodiments.

[0044] It is understood that the packaging machine of this utility model uses the aforementioned feeding mechanism, such that the conveying component 2 of the feeding mechanism is installed on the machine body 1 and is used to absorb and feed the material in the bag bin 11 to the positioning bin 12. The first drive module 21 is fixed inside the machine body 1, and the first transmission link 23 is rotatably connected to the machine body 1 and fixed to the upper arm 25. The first drive module 21 is drive-connected to the first transmission link 23 and is used to drive the first transmission link 23 to reciprocate the upper arm 25. The second drive module 22 is fixed to the upper arm 25. The first transmission link 23 is hollow inside, and the second transmission link 24 is disposed inside the hollow and rotatably connected to the upper arm 25. The second drive module 22 is drive-connected to the lower arm 26 through the second transmission link 24 and is used to drive the second transmission link 24 to reciprocate the lower arm 26. The conveying module 27 is installed on the forearm 26, so that the first drive module 21 drives the first transmission link 23 to drive the upper arm 25 to swing back and forth. The upper arm 25 drives the second drive module 22, the second transmission link 24, the forearm 26 and the conveying module 27 to move back and forth. At the same time, the second drive module 22 drives the second transmission link 24 to drive the forearm 26 to swing back and forth. The forearm 26 drives the conveying module 27 to swing back and forth, thus forming a coaxial double swing arm mode. The upper arm 25 and the forearm 26 combine different angles and drive the conveying module 27 to transport the material from the bag bin 11 to the positioning bin 12, that is, to the bag gripping position of the packaging machine. Because there are no sliding parts, the transmission efficiency is high and the speed is fast. The first transmission link 23 and the second transmission link are located at the bottom of the machine body 1, which is small in size, easy to maintain, and can be used in corrosive environments.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
