[0056] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0057] Embodiment 1 of the multi-pack packaging machine provided by this utility model:

[0058] like Figures 1 to 14 As shown, this utility model provides a multi-pack packaging machine, including a standing mechanism 1, a feeding mechanism 2, a sorting mechanism 3, and a sealing mechanism 4. The standing mechanism 1 is used to stand up packages 5, the feeding mechanism 2 is used to transport multiple standing packages 5, the sorting mechanism 3 extends in the front-to-back direction, and is used to press the multiple standing packages 5 from the feeding mechanism 2 and transport the packages 5 to the inlet end of the sealing mechanism 4. The sealing mechanism 4 is used to bag and seal the multiple standing packages 5. For ease of description, this utility model is referred to as... Figure 1 The length of the feeding mechanism 3 extends in the front-to-back direction, which is perpendicular to the paper surface. The width of the feeding mechanism 3 extends in the left-to-right direction, and the front-to-back direction is perpendicular to the left-to-right direction.

[0059] In this invention, the flat material package 5 is placed upright after passing through the uprighting mechanism 1. The feeding mechanism 2 transports multiple upright material packages 5 to the sorting mechanism 3. The sorting mechanism 3 can compress the multiple material packages 5 and transport them to the sealing mechanism 4, thus realizing the bagging and sealing of the material packages 5. Because the sorting mechanism 3 is provided, multiple material packages 5 can be compressed, reducing the gap between adjacent material packages 5, thereby reducing the volume of the material packages 5 and facilitating the bagging of multiple material packages 5. This invention is particularly suitable for the use of material packages 5 made of soft and fluffy materials such as wet wipes and tissues.

[0060] As Figure 3 and Figure 7 shown, the material sorting mechanism 3 includes a material sorting support 31 connecting the discharge end of the feeding mechanism 2 and the feeding end of the packaging mechanism 4, a horizontal support plate 32 slidingly arranged above the material sorting support 31 in the front-rear direction, a moving clamp plate 33 and a turnover clamp plate 34 oppositely arranged on the horizontal support plate 32. The moving clamp plate 33 is movably arranged relative to the turnover clamp plate 34 to clamp or release the material package 5. The turnover clamp plate 34 is arranged close to the packaging mechanism 4, and the turnover clamp plate 34 is rotatably arranged relative to the horizontal support plate 32 about an axis in the left-right direction.

[0061] In the utility model, the moving clamp plate 33 is driven to move away from the turnover clamp plate 34, so that the multiple material packages 5 from the feeding mechanism 2 enter between the moving clamp plate 33 and the turnover clamp plate 34, and then the moving clamp plate 33 is driven to move close to the turnover clamp plate 34, so that the multiple material packages 5 are compressed under the clamping action of the moving clamp plate 33 and the turnover clamp plate 34. The horizontal support plate 32 drives the moving clamp plate 33, the turnover clamp plate 34 and the material package 5 to the packaging mechanism 4, and the packaging mechanism 4 can push the material package 5 out of the moving clamp plate 33 and the turnover clamp plate 34. During the pushing process, the turnover clamp plate 34 is rotated to a horizontal state, and since the packaging mechanism 4 no longer hinders the turnover clamp plate 34, the horizontal support plate 32 can be reset at this time to continue receiving the material package 5 from the feeding mechanism 2. The arrangement of the turnover clamp plate 34 enables the horizontal support plate 32 to be reset without waiting for the material package 5 to be pushed out when the material package 5 is pushed in the packaging mechanism 4, so that the next group of material packages 5 can be clamped and transported, thereby saving time and improving production efficiency.

[0062] As Figure 7 shown, the material sorting mechanism 3 further includes a first driving cylinder 36, a second driving cylinder 37 and a third driving cylinder 38. The first driving cylinder 36 is arranged at the bottom of the material sorting support 31 and is used to drive the horizontal support plate 32 to move in the front-rear direction. The material sorting support 31 is further provided with a first sliding rail, and the horizontal support plate 32 is provided with a first sliding block matched with the first sliding rail. The second driving cylinder 37 is arranged on the horizontal support plate 32, and the end of the output shaft of the second driving cylinder 37 is connected to the moving clamp plate 33 to drive the moving clamp plate 33 to move. The third driving cylinder 38 is arranged at the bottom of the material sorting support 31 and is used to drive the turnover clamp plate 34 to rotate relative to the horizontal support plate 32. Specifically, the turnover clamp plate 34 is rotatably arranged on the horizontal support plate 32 through a rotating block 35, the upper end of the rotating block 35 is connected to the turnover clamp plate 34, the lower end of the rotating block 35 is rotatably connected to the end of the output shaft of the third driving cylinder 38, and the middle part of the rotating block 35 is arranged at the edge of the horizontal support plate 32 through a rotating shaft. The end of the output shaft of the first driving cylinder 36 is connected to the horizontal support plate 32 through a floating joint, which can prevent the output shaft of the first driving cylinder 36 from being parallel to the first sliding rail, causing the movement of the horizontal support plate 32 to be blocked, or even causing the first driving cylinder 36 to stop and be damaged.

[0063] The first driving cylinder 36, the second driving cylinder 37 and the third driving cylinder 38 in the embodiment can be replaced by linear motion mechanisms such as hydraulic cylinders and linear motors, or can be driven by rotating mechanisms through mechanisms such as ball screws, and the present application is not limited in this regard.

[0064] As shown in the drawings, Figure 2 The vertical material mechanism 1 includes a first belt conveyor 11 arranged in the left-right direction, a second belt conveyor 12 arranged on both sides of the first belt conveyor 11, and a twisted belt 13. The second belt conveyor 12 is arranged vertically. One end of the twisted belt 13 is coaxially arranged with the corresponding end of the first belt conveyor 11, and the other end is arranged in parallel with the corresponding end of the second belt conveyor 12. In the direction from the horizontal end of the twisted belt 13 to the vertical end of the twisted belt 13, the distance between the twisted belt 13 and the first belt conveyor 11 gradually decreases.

[0065] In the present application, the material bag 5 is horizontally placed at the feeding end of the vertical material mechanism 1, and the material bag 5 is gradually changed from a horizontal state to a vertical standing state under the driving of the first belt conveyor 11, the second belt conveyor 12 and the twisted belt 13, realizing the vertical material function.

[0066] In some other embodiments, the distance between the first belt conveyor 11 and the twisted belt 13 is adjustable, so that it can be applied to material bags 5 of different sizes, thereby enhancing the versatility of the packaging machine.

[0067] As shown in the drawings, Figures 3 to 6 The feeding mechanism 2 includes a feeding support arranged in the front-rear direction, a driving sprocket and a driven sprocket arranged at both ends of the feeding support respectively, a chain cooperating with the driving sprocket and the driven sprocket, a plurality of chain plates arranged on the chain in the length direction of the chain, and a plurality of partition plates respectively connected to the chain plates. Two partition plates are used to place a single vertical material bag 5. The partition plate is an L-shaped plate.

[0068] In the present application, the vertical material mechanism 1 delivers the single material bag 5 between the two partition plates, the driving sprocket rotates to drive the chain, the driven sprocket, the chain plate and the partition plate to rotate synchronously, and the distance between the two partition plates is then changed, and then the next single material bag 5 enters the next pair of partition plates, until the group of material bags 5 reaches the specified number of material bags 5, and then the group of material bags 5 is delivered to the discharge end of the feeding mechanism 2. For example, the number of a group of material bags 5 is ten, five, etc., which can be set as needed. The feeding mechanism 2 of the present embodiment can realize the placement and delivery of the vertical material bag 5, and is convenient for subsequent material sorting and bagging processes.

[0069] As shown in the drawings, Figures 4 to 6As shown, the driving sprocket, driven sprocket, chain, chain plate and partition plate are two groups. The first group of driving sprocket 211 is fixedly sleeved on the first rotating shaft 231 at one end of the feeding support, and the first group of driven sprocket 212 is rotatably sleeved on the second rotating shaft 232 at the other end of the feeding support. The second group of driving sprocket 221 is fixedly sleeved on the second rotating shaft 232, and the second group of driven sprocket 222 is rotatably sleeved on the first rotating shaft 231. The first group of partition plate 261 is connected to the first group of chain 241 through the first group of chain plate 251. The second group of partition plate 262 is connected to the second group of chain 242 through the second group of chain plate 252. The first group of chain 241 is correspondingly sleeved on the first group of driving sprocket 211 and the first group of driven sprocket 212, and the second group of chain 242 is correspondingly sleeved on the second group of driving sprocket 221 and the second group of driven sprocket 222. The first group of partition plate 261 and the second group of partition plate 262 are arranged at intervals.

[0070] In this embodiment, the first rotating shaft 231 is driven to rotate, driving the first group of driving sprocket 211, the first group of chain 241, the first group of driven sprocket 212, the first group of chain plate 251 and the first group of partition plate 261 to rotate synchronously, realizing the placement and conveying of the first group of material package 5. When the first group of material package 5 is being conveyed and unloaded, the second rotating shaft 232 is driven to rotate, driving the second group of driving sprocket 221, the second group of chain 242, the second group of driven sprocket 222, the second group of chain plate 252 and the second group of partition plate 262 to rotate synchronously, realizing the placement of the second group of material package 5. By setting two groups of partition plates and corresponding driving structures, one group of partition plate can realize feeding and unloading while the other group of partition plate can realize loading, thereby saving time and improving production efficiency.

[0071] As shown in the figure, Figures 4 to 6 The first rotating shaft 231 is driven by the first motor 271 through the first belt transmission structure, and the second rotating shaft 232 is driven by the second motor 272 through the second belt transmission structure. The first motor 271 and the second motor 272 are driven respectively. The first group of driving sprocket 211, the first group of driven sprocket 212, the first group of chain 241, the second group of driving sprocket 221, the second group of driven sprocket 222 and the second group of chain 242 are two, so that the first group of chain plate 251 and the second group of chain plate 252 are evenly stressed, and the material package 5 is conveyed stably.

[0072] In some embodiments, the distance between the adjacent two partition plates or the thickness of the partition plate can be adjusted, so that it can be applied to material packages 5 of different thickness sizes, enhancing the versatility of the packaging machine.

[0073] As shown in the figure, Figure 3As shown, the feeding mechanism 2 further comprises a pushing assembly arranged at the tail end of the feeding support. The pushing assembly comprises a pushing support 27 arranged above the feeding support, a toothed pushing plate 28 arranged to move in the left-right direction to push the plurality of packs 5 into the moving clamp plate 33 and the turnover clamp plate 34, and a lifting structure 29 arranged to drive the toothed pushing plate to slide up and down.

[0074] In this embodiment, when the packs 5 are conveyed to the tail end of the feeding support, the lifting mechanism drives the toothed pushing plate 28 to descend to a position at the same height as the packs 5, and then the pushing plate moves towards the packs 5 in the left-right direction to push the packs 5 into the moving clamp plate 33 and the turnover clamp plate 34, and then the pushing plate is reset. Since the toothed pushing plate 28 has a plurality of toothed plates, each toothed plate corresponds to push one pack 5, and interference with the partition plate will not occur when the packs 5 are pushed.

[0075] As shown, Figure 8 The packaging mechanism 4 comprises a support seat 41 arranged at the front side of the sorting mechanism 3 and extending in the left-right direction, a bagging module 42, a bag sleeving module 43, and a sealing module 44 arranged on the support seat 41. The bagging module 42 comprises a rotating seat 421 arranged vertically and rotating around an axis in the left-right direction, two duckbill-shaped dies 422 for opening the packaging bag, and a pushing assembly. The rotating seat 421 can be driven to rotate by a bagging driving motor 428. The upper and lower ends of the rotating seat 421 are respectively provided with mounting holes penetrating in the left-right direction, and the two duckbill-shaped dies 422 are respectively arranged at the two mounting holes. The pushing assembly comprises a pushing head 423 arranged to move in the left-right direction to push the packs 5 between the moving clamp plate 33 and the turnover clamp plate 34 into the opened packaging bag through the corresponding mounting hole. The bag sleeving module 43 is used to sleeve the packaging bag on the duckbill-shaped die 422. The sealing module 44 is used to seal and cut the edges of the packaging bag containing the packs 5. The pushing head 423 is connected with a pushing rod, and the pushing rod is driven by a belt machine to realize reciprocating motion in the left-right direction.

[0076] In this embodiment, the first driving cylinder 36 drives the packs 5 on the horizontal support plate to move to the tail end of the sorting support 31 and directly face the inlet of the duckbill-shaped die 422. The duckbill-shaped die 422 is sleeved with a packaging bag by the bag sleeving module 43, the pushing head 423 pushes the packs 5 into the duckbill-shaped die 422, i.e. into the packaging bag, the pushing head 423 continues to push to make the packaging bag containing the packs 5 separate from the duckbill-shaped die 422 and enter the sealing module 44 to realize sealing and edge cutting. Since the packs 5 have been compressed, the packs 5 are more convenient to pack into the packaging bag. And since there are two duckbill-shaped dies 422, one duckbill-shaped die 422 can perform bagging work while the other duckbill-shaped die 422 is used for bagging work, and through the rotation of the rotating seat 421, the positions of the two duckbill-shaped dies 422 can be switched, thereby saving time and improving work efficiency.

[0077] AsFigure 9 and Figure 10 As shown, the duckbill-shaped mold head 422 includes horizontal fixing plates 4221 fixed to the upper and lower edges of the mounting hole, and C-shaped plates 4222 rotatably disposed on both sides of the mounting hole about a vertical axis. The bagging module 42 also includes a bagging drive cylinder 424 disposed on the side of the rotating seat 421 opposite to the duckbill-shaped mold head 422, a push plate 425 connected to the output shaft end of the bagging drive cylinder 424, two top posts 426 disposed on the push plate 425, and an L-shaped rotating bar 427 rotatably disposed on the side edge of the mounting hole about a vertical axis. One end of the L-shaped rotating bar 427 is connected to the C-shaped plate 4222, and the other end is correspondingly disposed with respect to the top post 426. The rotating seat 421 has clearance holes for the top post 426 to pass through. A torsion spring for resetting is provided at the pivot of the L-shaped rotating bar 427. To facilitate the top post 426 abutting against the L-shaped rotating bar 427, the L-shaped rotating bar 427 is also provided with a column with a ball head that cooperates with the top post 426.

[0078] In this embodiment, when bagging the duckbill-shaped die 422, the output shaft of the bagging drive cylinder 424 extends, driving the push plate 425 and the two top posts 426 to move. The top posts 426 pass through the clearance hole and push the L-shaped rotating bar 427 to rotate, causing the two C-shaped plates 4222 to move closer to each other, thus narrowing the outlet of the duckbill-shaped die 422, making it easier for the packaging bag to be placed on the duckbill-shaped die 422. After bagging is completed, the output shaft of the bagging drive cylinder 424 retracts, causing the push plate 425 and the two top posts 426 to retract synchronously. At this time, the torsion spring drives the L-shaped rotating bar 427 to rotate in the opposite direction, and the two C-shaped plates 4222 move away from each other, thus widening the outlet of the duckbill-shaped die 422, tightening the packaging bag, and making it easier for the material bag 5 to be put into the packaging bag.

[0079] like Figure 11 and Figure 12 As shown, the bagging module 43 includes a bag storage element, a bag retrieval element located below the bag storage element, and a bagging element. The bag storage element includes a storage frame 431 with an open bottom and an inclined arrangement for holding packaging bags. The bag retrieval element includes a rotating plate 432 rotatably arranged about an axis in the front-back direction, and a bag retrieval suction cup 433 on the rotating plate 432 for adsorbing packaging bags. The bagging element includes an upper suction cup structure 434, a lower suction cup structure 435, and a bagging drive structure. The bagging drive structure is used to drive the upper suction cup structure 434 and the lower suction cup structure 435 to move closer or further apart, and to drive the upper suction cup structure 434 and the lower suction cup structure 435 to move in the left-right direction, so as to open the packaging bag and fit it onto the duckbill-shaped mold head 422. The upper suction cup structure 434 includes an L-shaped upper connecting rod and an upper suction cup arranged on the L-shaped upper connecting rod, and the lower suction cup structure 435 includes an L-shaped lower connecting rod and a lower suction cup arranged on the L-shaped lower connecting rod. The bag-removing suction cup 433, the upper suction cup, and the lower suction cup are all connected to a negative pressure device.

[0080] In the embodiment, a plurality of stacked packaging bags are stored in the storage frame 431. The rotating plate 432 is rotated upward, and the bag taking suction cup 433 adsorbs the bottom of the packaging bag. The rotating plate 432 is rotated downward, and the bag taking suction cup 433 takes out the packaging bag from the bottom opening of the storage frame 431. The bag sleeving driving structure drives the upper suction cup and the lower suction cup to approach each other, and adsorbs the upper part and the lower part of the opening of the packaging bag, respectively. The bag sleeving driving structure drives the upper suction cup and the lower suction cup to move away from each other, so that the opening of the packaging bag is stretched, and at the same time, the bag sleeving driving structure drives the upper suction cup and the lower suction cup to move and drive the stretched packaging bag to be sleeved on the duckbill-shaped die 422, thereby realizing the bag sleeving function.

[0081] As shown in Figure 11 and Figure 12 , the bag sleeving driving structure includes a vertical mounting plate 4361 slidably arranged on the support seat 41 along the left-right direction, an upper rotating shaft 4362 and a lower rotating shaft 4363 rotatably arranged on the upper and lower ends of the vertical mounting plate 4361 along the front-rear direction, an upper connecting plate 4364, a lower connecting plate 4365, a connecting rod 4366, a rotating plate 4367, and a sliding groove 4368 arranged on the support seat 41. One end of the upper rotating shaft 4362 is connected to the upper suction cup structure 434, and the other end is connected to the upper connecting plate 4364. One end of the lower rotating shaft 4363 is connected to the lower suction cup structure 435, and the other end is connected to the lower connecting plate 4365. The connecting rod 4366 connects the upper connecting plate 4364 and the lower connecting plate 4365. The sliding groove 4368 is arranged along the movement direction of the vertical mounting plate 4361, and the sliding groove 4368 includes a first horizontal groove, a second horizontal groove located obliquely below the first horizontal groove, and an inclined groove connecting the first horizontal groove and the second horizontal groove. The upper end of the rotating plate 4367 is fixedly arranged on the end of the lower rotating shaft 4363 away from the lower suction cup structure 435, and the lower end is slidably arranged in the sliding groove 4368.

[0082] In the embodiment, the vertical mounting plate 4361 slides along the left-right direction, drives the upper suction cup structure 434 and the lower suction cup structure 435 to move close to the duckbill-shaped die 422, and at the same time, drives the lower end of the rotating plate 4367 to slide from the first horizontal groove into the inclined groove, so that the rotating plate 4367 rotates, drives the lower rotating shaft 4363 to rotate, drives the upper rotating shaft 4362 to rotate in the opposite direction through the lower connecting plate 4365, the connecting rod 4366 and the upper connecting plate 4364, and further drives the upper suction cup structure 434 and the lower suction cup structure 435 to separate, so as to stretch the packaging bag and sleeve it on the duckbill-shaped die 422. When the vertical mounting plate 4361 slides in the opposite direction along the left-right direction, the working process is similar to the above, and the upper suction cup structure 434 and the lower suction cup structure 435 are retracted at the same time.

[0083] As shown in Figure 11 and Figure 12As shown, the bag driving structure further comprises a bag driving motor arranged on the support base 41, and the bag driving motor drives the vertical mounting plate 4361 to slide on the support base 41 through a belt transmission mechanism. The support base 41 is further provided with a second sliding rail, and the vertical mounting plate 4361 is provided with a second sliding block matched with the second sliding rail. The upper end of the connecting plate is connected with the L-shaped upper connecting rod through the upper damping structure, and the lower end of the connecting plate is connected with the L-shaped lower connecting rod through the lower damping structure, thereby improving the stability of the upper suction disc structure 434 and the lower suction disc structure 435 during the bag supporting process.

[0084] As shown in Figure 13 and Figure 14 , the sealing module 44 comprises a third belt conveyor 441 arranged at one end of the duckbill-shaped die head 422 along the left-right direction, a first clamping element 442 arranged above the third belt conveyor 441, an abutting plate 444 movably arranged at the discharge end of the third belt conveyor 441, a second clamping element 443 arranged on both sides of the third belt conveyor 441 respectively, two heating conical blocks 445, two cutting knives 446, and a waste suction bucket 447. The two heating conical blocks 445 are arranged at the feeding end of the third belt conveyor 441 along the up-down direction, and the two heating conical blocks 445 can approach or move away from each other to heat the opening of the packaging bag. The two cutting knives 446 are arranged along the up-down direction and located between the heating conical blocks 445 and the duckbill-shaped die head 422, and the two cutting knives 446 can approach or move away from each other to cut the burrs of the packaging bag. The waste suction bucket 447 is arranged below the two cutting knives 446 for suction of the cut burrs.

[0085] In this embodiment, the material pushing head 423 pushes the packaging bag containing the material bag 5 onto the third belt conveyor 441, and the abutting plate 444 stops the packaging bag. The first clamping element 442, the second clamping element 443, and the third clamping element are respectively clamped and fixed to the top and both sides of the packaging bag. The two heating conical blocks 445 approach each other to heat the opening of the packaging bag to achieve sealing. The two cutting knives 446 approach each other to cut the excess burrs at the sealing position of the packaging bag. The waste suction bucket 447 sucks away the cut burrs. The third belt conveyor 441 can output the finished product. The sealing module 44 can realize the functions of sealing, cutting, and waste suction of the packaging bag, has high automation degree, and has high production efficiency.

[0086] As shown in Figure 13As shown in the drawings, the top surface of one of the two heating conical blocks 445 has a protrusion, and the top surface of the other heating conical block 445 has a groove matched with the protrusion, so that the clamping effect on the packaging bag is better when sealing, and the sealing quality is better. The heating conical block 445 is provided with a heating pipe to heat the heating conical block 445. The waste bucket 447 can be connected with a negative pressure device to realize the adsorption of the cut edge.

[0087] As shown in the drawings, Figure 14 The sealing module 44 further comprises a sealing driving structure for driving the two heating conical blocks 445 and the two cutting knives 446 to approach and move away from each other, respectively. The sealing driving structure comprises a sealing support, the sealing support is provided with a third sliding rail 4481 arranged vertically, and an upper sliding block structure 4482 and a lower sliding block structure 4483 matched with the third sliding rail 4481, the upper heating conical block 445 and the cutting knife 446 are arranged on the upper sliding block structure 4482, and the lower heating conical block 445 and the cutting knife 446 are arranged on the lower sliding block structure 4483. The bottom of the sealing support is further provided with a sealing driving motor, and the end of the output end of the sealing driving motor is provided with a rotating rod 4484, the two ends of the rotating rod 4484 are connected with the upper sliding block structure 4482 and the lower sliding block structure 4483 through a first connecting rod 4485 and a second connecting rod 4486 respectively. When the sealing driving motor rotates, the rotating rod 4484 rotates, and the upper sliding block structure 4482 and the lower sliding block structure 4483 are driven to move close to or away from each other along the length direction of the third sliding rail 4481 through the first connecting rod 4485 and the second connecting rod 4486 respectively, thereby realizing sealing and edge cutting.

[0088] As shown in the drawings, Figure 13 And 14 The sealing module 44 further comprises a lifting adjusting assembly for driving the third belt conveyor 441 to adjust up and down, so that it can be suitable for material bags 5 of different heights.

[0089] The total working process of the utility model is as follows:

[0090] The horizontal material package 5 is gradually changed from horizontal state to vertical state by the first belt conveyor 11, the second belt conveyor 12 and the twisting belt 13 of the vertical material mechanism 1, and is conveyed between two separation plates of the feeding mechanism 2. When the group of separation plates reaches the specified number of material packages 5, it is conveyed to the tail end of the feeding mechanism 2. The tooth-shaped material pushing plate 28 of the material pushing assembly pushes the group of material packages 5 into the moving clamping plate 33 and the turnover clamping plate 34, and clamps the material package 5. Then the clamped material package 5 is conveyed to the position corresponding to the duckbill-shaped die 422, and the pushing head 423 pushes the material package 5 into the packaging bag of the duckbill-shaped die 422. The turnover clamping plate 34 can be turned to the horizontal state and returned to the reset position. The pushing head 423 continues to push the material package 5 sleeved with the packaging bag into the third belt conveyor 441 to the abutting plate 444, and the first clamping element 442 and the second clamping element 443 clamp the material package 5. At this time, the two heating conical blocks 445 and the two cutting knives 446 correspond to the close extrusion, heat sealing and edge cutting of the packaging bag, and the cut-off burr is discharged through the waste suction barrel 447. The packaged material package 5 is output through the third belt conveyor 441.
