Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a paper cup packaging machine. Background Art

[0002] After paper cups or paper bowls are processed and formed by a forming machine, multiple paper cups or paper bowls are sleeved and stacked together to form strips of paper cups or paper bowls, and then they are packaged with packaging bags.

[0003] The utility model patent with the application number CN202221428737.X discloses a vertical paper cup packaging machine, which includes a paper cup temporary storage cylinder assembly, an electrical control box, a plastic film placement assembly, a film pulling assembly, a film feeding assembly, a collar former assembly, a longitudinal sealing assembly, a deflector assembly, a transverse sealing and cutting assembly, a cup turning and discharging assembly, a labeling assembly, and a machine frame; the paper cups pass through the machine frame vertically in sequence and pass through the paper cup temporary storage cylinder assembly, the collar former assembly, the longitudinal sealing assembly, the deflector assembly, the transverse sealing and cutting assembly, the cup turning and discharging assembly, and the labeling assembly arranged from top to bottom in sequence to complete the packaging.

[0004] However, the above technical solution has the following technical problems: After the existing packaged paper cups fall into the cup turning and discharging assembly, the paper cups are limited by the right fixed plate and the left moving plate. The turning cylinder retracts, pulling the right fixed plate and the left moving plate to rotate around the bearing seat. After the turning cylinder retracts, the paper cups change from a vertical state to a horizontal state. The cup leaking cylinder retracts, driving the left moving plate to rotate and open at a certain angle. At this time, the paper cups will roll out due to gravity and become horizontal paper cups. At this time, the cup leaking cylinder and the turning cylinder return, and the horizontal paper cups are blocked by the blocking strip. At this time, the labeling assembly pushes the label towards the horizontal paper cups. After completion, the blocking strip opens, and the horizontal paper cups roll down. Thus, the discharging of the paper cups is completed. The structure is complex, the discharging steps are cumbersome, and the subsequent packaged paper cups need to wait for the previous paper cups to be discharged before they can be discharged, affecting the processing efficiency. Summary of the Utility Model

[0005] Based on the above problems, the utility model provides a paper cup packaging machine with a simple structure and improved processing efficiency.

[0006] To achieve the above object, the utility model provides the following technical solutions: A paper cup packaging machine, including a frame, on which a stacking mechanism, a pushing mechanism, a film feeding mechanism, a longitudinal sealing mechanism, a transverse sealing and cutting mechanism, a discharging mechanism, a collar former and a blanking cylinder are provided. The stacking mechanism is arranged at the top of the frame and is used for placing stacked paper cups. The blanking cylinder is vertically arranged and penetrates up and down below the stacking mechanism. The pushing mechanism is used to push the stacked paper cups from the stacking mechanism to the position of the blanking cylinder. The film feeding mechanism is used to convey the plastic film to the position of the collar former. The collar former is used for forming the plastic film into a tubular shape, and the formed plastic film is placed outside the blanking cylinder. On the left and right sides of the blanking cylinder and corresponding to the position below the collar former, a film pulling assembly is provided, and the film pulling assembly is used to pull the plastic film downward. The longitudinal sealing mechanism is arranged at the front end of the blanking cylinder for sealing the side edges of the plastic film. The transverse sealing and cutting mechanism is arranged below the blanking cylinder for sealing and cutting the ports of the plastic film. A blanking channel is arranged between the discharging mechanism and the blanking cylinder. The blanking channel is hollow and has openings at both the upper and lower ends. The upper opening of the blanking channel corresponds to the lower port of the blanking cylinder, and the lower opening of the blanking channel corresponds to the discharging mechanism. The discharging mechanism is used to discharge the paper cups after packaging is completed.

[0007] By adopting the above technical solution, the stacking mechanism cooperates with an external forming machine, so that the paper cups formed by the forming machine are placed into the stacking mechanism and stacked one by one into a row of paper cups. When the number of stacked paper cups reaches a certain amount, the pushing mechanism pushes the row of paper cups to the position of the blanking cylinder. Before the paper cups are pushed to the blanking cylinder, the film feeding mechanism conveys the plastic film to the position of the collar former. The plastic film is made into a cylindrical structure by the collar former and wrapped around the outside of the blanking cylinder. And through the longitudinal sealing mechanism and the transverse sealing and cutting mechanism, the side and bottom of the formed plastic film are sealed, so that the plastic film is in a bag shape. At this time, a row of paper cups fall from the upper port of the blanking cylinder to its lower port and are contained by the bag-shaped plastic film. The setting of the film pulling assembly pulls the plastic film along the direction of the discharging mechanism, and at the same time, the paper cups placed in the blanking cylinder move with the movement of the plastic film. After the paper cups in the blanking cylinder are completely separated from the blanking cylinder position, the transverse sealing and cutting mechanism seals and cuts the top of the blanking cylinder, thereby completing the packaging of a row of paper cups. After the packaging is completed, the paper cups directly fall to the discharging mechanism along the blanking channel and are directly discharged from the discharging mechanism, thereby completing the discharging of a row of paper cups without waiting. After the paper cup packaging is completed, it directly falls to the discharging mechanism along the blanking channel for discharging, simplifying the discharging steps and further improving the processing efficiency. The setting of the blanking channel plays a role in guiding the falling of the packaged paper cups. When the plastic film moves along the blanking channel direction, the setting that the lower port of the blanking cylinder corresponds to the upper opening position of the blanking channel makes the bottom end of the plastic film be pre-placed into the blanking channel in advance with the pulling of the film pulling assembly, realizing pre-guidance. When the paper cup packaging is completed, it is sealed and cut by the transverse sealing and cutting mechanism, and the paper cup directly falls to the discharging mechanism along the blanking channel position for discharging, and the discharging position is more accurate and the structure is more reliable. When the transverse sealing and cutting mechanism seals, the sealing position is the bottom of one plastic film and the top of the adjacent plastic film, and the cutting position is the middle of the two plastic films. When the transverse sealing and cutting mechanism cuts the plastic film placed below, the bottom of the plastic film above is simultaneously in a sealed state, saving time, facilitating the packaging of the next row of paper cups, and improving efficiency. The structures of the film feeding mechanism, the longitudinal sealing mechanism, the transverse sealing and cutting mechanism, the film pulling assembly and the collar former have been disclosed in the background art, so the above structures will not be described in detail.

[0008] The present utility model is further provided that: the stacking mechanism includes a stacking channel and a feeding channel that are both through at both ends. The feeding channel is arranged above the stacking channel. The pushing mechanism includes a pushing plate and a pushing cylinder. The pushing plate is connected to the stacking channel. The pushing cylinder moves towards the blanking cylinder direction to make the lower port of the stacking channel communicate with the blanking cylinder, or moves away from the blanking cylinder direction to make the upper port of the stacking channel communicate with the lower port of the feeding channel.

[0009] By adopting the above technical solution, paper cups are stacked in the pushing channel through the feeding channel. After the paper cups are stacked in the stacking channel, they are moved to the position of the blanking cylinder together with the pushing channel under the drive of the pushing cylinder. When the stacking channel is communicated with the blanking cylinder, the paper cups fall from the position of the blanking cylinder and are separated from the stacking channel. After the paper cups fall from the position of the blanking cylinder, the pushing cylinder resets, and the pushing channel is communicated with the feeding channel, and the paper cups continue to be stacked in the stacking channel through the feeding channel. One or more stacking mechanisms can be provided, and preferably two are provided in the present utility model. The two stacking channels are alternately matched with a blanking cylinder for blanking, further improving the processing efficiency.

[0010] The present utility model is further provided with: a material blocking component is arranged at the lower port of the feeding channel, and the material blocking component includes a material blocking cylinder and a material blocking plate. The material blocking cylinder can drive the material blocking plate to open or close the lower port of the feeding channel.

[0011] By adopting the above technical solution, when the number of paper cups stacked in the stacking channel reaches a certain amount, the pushing cylinder pushes the stacking channel to move along the position of the blanking cylinder. At this time, the material blocking cylinder drives the material blocking plate to move to close the lower port of the feeding channel to prevent the paper cups from leaking out of the feeding channel. When the pushing cylinder drives the stacking channel to reset, the material blocking cylinder also drives the material blocking plate to reset, opening the lower port of the feeding channel to communicate with the stacking channel, and the paper cups are stacked in the stacking channel again with the opening of the lower port of the feeding channel. The structure is reasonable. One or two material blocking components are provided, and preferably two are provided in the present utility model. The material blocking plates of the two material blocking components are arranged oppositely. When the material blocking cylinder is driven, the moving distance of the material blocking plate is shortened, and the lower port of the feeding channel can be opened or closed more quickly.

[0012] The present utility model is further provided with: a blanking seat is arranged at the upper end of the frame, the stacking channel is arranged in the blanking seat, the feeding channel is arranged at the upper end of the blanking seat, a guide rod is arranged on the side of the pushing plate facing the cylinder, and a guide sleeve adapted to the guide rod is arranged at the corresponding position of the blanking seat for the guide rod. The guide rod slides in cooperation with the guide sleeve under the drive of the pushing cylinder to drive the pushing rod.

[0013] By adopting the above technical solution, the arrangement of the guide sleeve and the guide rod plays a role in guiding the movement of the pushing rod. When the pushing cylinder expands and contracts, the guide rod also slides along the position of the guide sleeve, and the movement of the pushing plate is more stable. Preferably, the pushing cylinder is arranged in the middle of the pushing plate, and two guide rods are arranged. Each guide rod is arranged at the upper and lower ends of the pushing plate and is arranged in the same direction as the pushing cylinder, further improving the structural stability.

[0014] The present utility model is further configured as follows: The stacking channel includes a mounting ring and a retaining rod. The upper and lower ends of the pushing plate are respectively connected to the mounting ring by screws. A plurality of retaining rods are provided, and the retaining rods are circumferentially distributed along the inner cavity of the mounting ring and form a cavity for stacking paper cups.

[0015] By adopting the above technical solution, the mounting ring and the retaining rod cooperate to form a cavity for stacking paper cups. The structure is simple, which is convenient for the pushing air cylinder to push the stacking channel to drive the paper cups to move. The pushing plate is preferably a long rod arranged vertically, and the mounting rings are respectively arranged at the upper and lower ends of the pushing plate by screws. While being convenient for disassembly and assembly, the stress distribution is more uniform, which is convenient for stably pushing the movement of the stacked paper cups. A fixing ring is arranged between the two mounting rings and sleeved on the outer periphery of the retaining rod. One or more fixing rings can be provided to fix the retaining rod, making the structure of the retaining rod more stable and not easily deformed.

[0016] The present utility model is further configured as follows: The discharging mechanism includes a motor, a driving roller, and a driven roller. A discharging conveyor belt is arranged between the driving roller and the driven roller. A driving wheel is arranged at one end of the driving roller, and an output wheel at one end of the motor is connected to the driving wheel by a belt.

[0017] By adopting the above technical solution, the output wheel of the motor controls the driving wheel to rotate through the belt. The driving wheel is connected to the driving roller, so that the driving roller can drive the driven roller to rotate through the discharging conveyor belt. When the paper cups are packaged and dropped onto the discharging conveyor belt, the cyclic transmission of the discharging conveyor belt can drive the packaged paper cups to discharge from the frame. Preferably, the discharging direction of the discharging mechanism is set towards the film feeding mechanism, and the film feeding mechanism is arranged at the rear end of the blanking cylinder. The structure is more reasonable, reducing the floor area of the frame and saving space.

[0018] The present utility model is further configured as follows: Anti-falling partition plates are arranged on both sides of the discharging conveyor belt along the discharging direction.

[0019] By adopting the above technical solution, the anti-falling partition plates play a role in blocking the materials, avoiding the packaged paper cups from falling off along both sides of the discharging conveyor belt when moving through the discharging conveyor belt, and further improving the reliability of the structure.

[0020] The present utility model is further configured as follows: A buffer assembly is arranged at the lower opening of the blanking channel. The buffer assembly includes two buffer brushes arranged oppositely, and a buffer cavity for the packaged paper cups to pass through is formed between the brush heads of the two buffer brushes.

[0021] By adopting the above technical solution, when the paper cup after packaging falls along the blanking channel, the buffer brush is arranged to play a buffering role, avoiding damage to the paper cup. One or more buffer components can be arranged, and preferably two in the present utility model, which are arranged up and down at the lower opening of the blanking channel to further improve the buffering effect.

Detailed Embodiment

[0029] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation to the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0030] See the attached Figures 1-6, A paper cup packaging machine disclosed by the present utility model includes a frame 1. A stacking mechanism 2, a pushing mechanism 3, a film feeding mechanism 4, a longitudinal sealing mechanism 5, a transverse sealing and cutting mechanism 6, a discharging mechanism 7, a collar former 8 and a blanking cylinder 9 are arranged on the frame 1. The stacking mechanism 2 is arranged at the top of the frame 1 and is used for placing stacked paper cups. The blanking cylinder 9 is vertically arranged and penetrates up and down below the stacking mechanism 2. The pushing mechanism 3 is used for pushing the stacked paper cups from the stacking mechanism 2 to the position of the blanking cylinder 9. The film feeding mechanism 4 is used for conveying a plastic film to the position of the collar former 8. The collar former 8 is used for forming the plastic film into a tubular shape, and the formed plastic film is placed outside the blanking cylinder 9. Film pulling assemblies 10 are arranged on the left and right sides of the blanking cylinder 9 and corresponding to the position below the collar former 8. The film pulling assemblies 10 are used for pulling the plastic film downward. The longitudinal sealing mechanism 5 is arranged at the front end of the blanking cylinder 9 for sealing the side edges of the plastic film. The transverse sealing and cutting mechanism 6 is arranged below the blanking cylinder 9 for sealing and cutting the ports of the plastic film. A blanking channel 17 is arranged between the discharging mechanism 7 and the blanking cylinder 9. The blanking channel 17 is hollow and has openings at both the upper and lower ends. The upper opening of the blanking channel 17 corresponds to the lower port of the blanking cylinder 9, and the lower opening of the blanking channel 17 corresponds to the discharging mechanism 7. The discharging mechanism 7 is used for discharging the paper cups after packaging is completed.The stacking mechanism 2 cooperates with an external forming machine, so that the paper cups formed by the forming machine are placed into the stacking mechanism 2 and stacked one by one into a row of paper cups. When the number of stacked paper cups reaches a certain amount, the pushing mechanism 3 pushes the row of paper cups to the position of the blanking cylinder 9. Before the paper cups are pushed to the blanking cylinder 9, the film feeding mechanism 4 conveys the plastic film to the position of the collar former 8. The plastic film is made into a tubular structure through the collar former 8 and wrapped around the outside of the blanking cylinder 9. The side and bottom of the formed plastic film are sealed by the longitudinal sealing mechanism 5 and the transverse sealing and cutting mechanism 6, making the plastic film in a bag shape. At this time, a row of paper cups fall from the upper port of the blanking cylinder 9 to its lower port and are contained in the bag-shaped plastic film. The setting of the film pulling assembly 10 pulls the plastic film along the direction of the discharging mechanism 7, and the paper cups placed in the blanking cylinder 9 move with the movement of the plastic film. When the paper cups in the blanking cylinder 9 are completely separated from the position of the blanking cylinder 9, the transverse sealing and cutting mechanism 6 seals and cuts the top of the blanking cylinder 9, thus completing the packaging of a row of paper cups. The packaged paper cups directly fall to the discharging mechanism 7 along the blanking channel 17 and are directly discharged from the discharging mechanism 7, thus completing the discharging of a row of paper cups without waiting. After the paper cups are packaged, they directly fall to the discharging mechanism along the blanking channel 17 for discharging, simplifying the discharging steps and further improving the processing efficiency. The setting of the blanking channel 17 plays a role in guiding the falling of the packaged paper cups. When the plastic film moves along the direction of the blanking channel 17, the setting that the lower port of the blanking cylinder 9 corresponds to the upper opening position of the blanking channel 17 enables one end of the bottom of the plastic film to be pre-placed into the blanking channel 17 in advance with the pulling of the film pulling assembly 10 to achieve pre-guidance. When the paper cups are packaged, they are sealed and cut by the transverse sealing and cutting mechanism 6, and the paper cups directly fall to the discharging mechanism 7 along the position of the blanking channel 17 for discharging, and the discharging position is more accurate and the structure is more reliable. When the transverse sealing and cutting mechanism seals, the sealing position is the bottom of one plastic film and the top of the adjacent plastic film, and the cutting position is the middle of the two plastic films. When the transverse sealing and cutting mechanism cuts the plastic film placed below, the bottom of the plastic film above is simultaneously in a sealed state, saving time, facilitating the packaging of the next row of paper cups, and improving the efficiency. The structures of the film feeding mechanism 4, the longitudinal sealing mechanism 5, the transverse sealing and cutting mechanism 6, the film pulling assembly 10, and the collar former 8 have been disclosed in the background technology, so the above structures will not be described in detail here.

[0031] This embodiment is further configured as follows: the stacking mechanism 2 includes a stacking channel 201 and a feeding channel 202 which are connected at both ends; the feeding channel 202 is arranged above the stacking channel 201; the pushing mechanism 3 includes a pushing plate 301 and a pushing cylinder 302; the pushing plate 301 is connected to the stacking channel 201; the pushing cylinder 302 moves toward the lower barrel 9 to connect the lower port of the stacking channel 201 with the lower barrel 9, or moves away from the lower barrel 9 to connect the upper port of the stacking channel 201 with the lower port of the feeding channel 202. The paper cups are placed into the push channel through the feed channel 202 for stacking. After the stacking is completed in the stacking channel 201, the paper cups are driven by the push cylinder 302 and moved to the position of the lower barrel 9 together with the push channel. When the stacking channel 201 is connected with the lower barrel 9, the paper cups fall from the lower barrel 9 and separate from the stacking channel 201. After the paper cups fall from the lower barrel 9, the push cylinder 302 is reset, and the push channel is connected with the feed channel 202. The paper cups continue to be placed into the stacking channel 201 from the feed channel 202 for stacking. The stacking mechanism 2 can be provided with one or more, and the present embodiment is preferably two. The two stacking channels 201 and the lower barrel 9 alternately cooperate with the material drop to further improve the processing efficiency.

When the stacked paper cups in the stacking channel 201 reach a certain amount, the pushing cylinder 302 pushes the stacking channel 201 to move along the position of the lower barrel 9. At this time, the blocking cylinder 1101 drives the blocking plate 1102 to move to close the lower port of the feeding channel 202 to prevent the paper cups from leaking out of the feeding channel 202. When the pushing cylinder 302 drives the stacking channel 201 to reset, the blocking cylinder 1101 also drives the blocking plate 1102 to reset, opens the lower port of the feeding channel 202 to make it connected with the stacking channel 201, and the paper cups are placed in the stacking channel 201 again for stacking as the lower port of the feeding channel 202 is opened. The structure is reasonable. The blocking assembly 11 is provided with one or two, and the present embodiment is preferably two. The blocking plates 1102 of the two blocking assemblies 11 are arranged opposite to each other. When the blocking cylinder 1101 is driven, the movement of the blocking plate 1102 is shortened, so that the lower port of the feeding channel 202 can be opened or closed more quickly.

The arrangement of the guide sleeve 14 and the guide rod 13 serves to guide the movement of the pusher rod. When the pusher cylinder 302 expands and contracts, the guide rod 13 also slides along the position of the guide sleeve 14, making the movement of the pusher plate 301 more stable. Preferably, the pusher cylinder 302 is arranged in the middle of the pusher plate 301, and two guide rods 13 are provided. Each guide rod 13 is arranged at the upper and lower ends of the pusher plate 301 and is arranged in the same direction as the pusher cylinder 302, further improving the structural stability.

The upper and lower ends of the pusher plate 301 are respectively connected to the mounting ring 2011 by screws. A plurality of retaining rods 2022 are provided, and each retaining rod 2022 is circumferentially distributed along the inner cavity of the mounting ring 2011 to form a cavity 15 for stacking paper cups. The mounting ring 2011 and the retaining rod 2022 cooperate to form a cavity 15 for stacking paper cups, with a simple structure and facilitating the pusher cylinder 302 to push the stacking channel 201 to drive the paper cups to move. The pusher plate 301 is preferably a long rod arranged vertically, and the mounting rings 2011 are respectively arranged at the upper and lower ends of the pusher plate 301 by screws. While facilitating disassembly and assembly, the stress distribution is more uniform and it is convenient to stably push the movement of the stacked paper cups.

The output wheel 706 of the motor 701 controls the driving wheel 705 to rotate through a belt (not shown in the figure). The driving wheel 705 is connected to the driving roller 702, so that the driving roller 702 can drive the driven roller 703 to rotate through the output conveyor belt 704. When the paper cup is packaged and dropped onto the output conveyor belt 704, the cyclic transmission of the output conveyor belt 704 can drive the packaged paper cup to discharge from the frame 1. Preferably, the discharging direction of the discharging mechanism 7 is set towards the film feeding mechanism 4.

One or more buffer assemblies 18 can be provided. In this embodiment, preferably two are provided and arranged up and down at the lower opening of the blanking channel 17 to further improve the buffering effect.
