Abstract
Description
Technical Field
[0001] This utility model relates to the bag feeding structure of a ton bag machine, specifically the bag feeding structure of a fully automatic ton bag machine. Background Technology
[0002] A ton bag machine is a device that automatically packages large quantities of bulk materials using ton bags. It is widely used in industries such as chemical, building materials, grain, feed, and mining for packaging materials in powder, granular, and flake forms.
[0003] In the ton bag feeding mechanism, the entire roll of ton bags is usually placed on the transmission roller. One end of the ton bag in the roll is conveyed to the bottom of the suction cup via the conveying device. At this time, the suction cup adsorbs the ton bag with the double-layer film structure, and then separates the double-layer film. The separated ton bag is conveyed to the filling area for subsequent processing by the bag feeding and lateral movement mechanism in the ton bag machine.
[0004] During the bag feeding process, before the ton bag enters the suction cup for separation after being conveyed, the position of the ton bag may sometimes shift. This will affect the subsequent separation effect of the suction cup on the double-layer film in the ton bag, thereby affecting the production progress of subsequent products. Utility Model Content
[0005] In order to solve the problems in related technologies, this utility model provides a bag feeding structure for a fully automatic ton bag machine. This device solves the problem that the position of the existing ton bags is offset after being conveyed, thus affecting the production progress.
[0006] To solve the above problems, the following technical solutions are provided:
[0007] The bag feeding structure of the fully automatic ton bag machine includes a support frame, a conveying mechanism for conveying ton bags is provided on the support frame, and a support plate is provided on the support frame corresponding to the end point of the conveying mechanism. The feature is that the support frame is provided with an automatic correction mechanism, which includes a detection component and an execution component.
[0008] The detection components are disposed at the bottom of the support plate. There are no fewer than three sets of detection components. Each set of detection components includes two position detection photoelectric sensors. The three sets of detection components are arranged in a symmetrical straight line around the center of the width direction of the support plate, forming a two-layer surrounding structure with the first set of detection components as the center. The width between the two position detection photoelectric sensors in the second set of detection components is the width value of the ton bag. Each position detection photoelectric sensor is provided with a first through hole on the support plate.
[0009] The execution component includes two push plates respectively disposed in the width direction of the conveying end point in the conveying mechanism. Each push plate is slidably engaged with the conveying mechanism. Two drive components are fixedly disposed on the conveying mechanism for driving the two push plates to move.
[0010] When the detection component detects a positional shift in the opening of the ton bag, the drive component that is closer to the ton bag in the width direction of the conveying mechanism drives the corresponding push plate to move and push the ton bag, so that the opening of the ton bag is in the middle position of the conveying mechanism.
[0011] Through the above technical solution, and with the automatic correction mechanism, six photoelectric sensors in three groups can detect the position of the bag opening on the support plate. When the detection finds that the position of the bag opening has shifted, the appropriate drive component is selected to push the push plate to adjust the position of the bag opening, thereby adjusting the position of the bag opening to the correct position. This facilitates the subsequent separation of the bag opening, thereby speeding up the work and ensuring the quality of bag opening separation.
[0012] Furthermore, two positioning and opening photoelectric sensors are also provided on the bottom side of the support plate away from the position detection photoelectric sensor, and a second through hole is provided on the support plate corresponding to each of the two positioning and opening photoelectric sensors.
[0013] Through the above technical solution, by setting up the photoelectric sensor for bag opening, it is possible to detect whether the position of the bag opening has been adjusted correctly, thereby ensuring that the separation mechanism is accurately started to separate the bag opening, thus ensuring the accuracy and quality of the separation action.
[0014] Furthermore, the conveying mechanism includes a conveyor frame, a conveyor belt, and a drive motor. The conveyor frame is inclinedly arranged on the support frame, with one end of the conveyor frame closer to the support plate being higher than the end farther from the support plate. On both sides of the width direction of the end of the conveyor frame closer to the support plate, there are drive wheels, which are connected by a drive roller. One of the drive wheels is fixedly connected to the output shaft of the drive motor. On both sides of the width direction of the end of the conveyor frame farther from the support plate, there are driven wheels, which are connected by a driven roller. The driven roller is connected to the drive roller via the conveyor belt in a transmission manner. Guard plates are respectively provided on both sides of the conveyor belt in the width direction. The bottom of each guard plate has a gap with the top of the conveyor belt. The length of each guard plate is set along the conveying direction of the conveying mechanism. Adjusting members for adjusting the corresponding guard plates are respectively provided on the conveyor frame on the side of the two guard plates that are farther apart from each other.
[0015] Through the above technical solution, by setting the first pulley, the driven roller can synchronously drive the first pulley to rotate when it rotates. The first pulley drives the second pulley to rotate synchronously through the first synchronous belt. After the second pulley rotates, it drives the third pulley to rotate through the second synchronous belt. After the third pulley rotates, it drives the idler roller to rotate, thereby providing a conveying action from the other side of the ton bag, improving the conveying effect of the ton bag, and thus speeding up the efficiency of ton bag delivery.
[0016] By setting up the guard plate, when the ton bag is running on the conveyor belt, the guard plate can accurately limit and guide it, and help correct the ton bag deviation. This ensures that when the ton bag is conveyed to the support plate, it can arrive at a precise and stable position, which greatly reduces the possibility of difficulty in opening the bag or failure to open the bag due to position deviation, thereby improving the efficiency of opening difficulties or failures.
[0017] Furthermore, roller assemblies are respectively provided on both sides of the width direction of the conveying starting point of the conveying mechanism; each roller assembly includes a roller bracket, a swing arm and a first cylinder, each roller bracket is mounted on the corresponding conveying frame, each first cylinder is fixedly mounted on the corresponding roller bracket, each swing arm includes an integrally formed straight section and a bent section, each first cylinder is used to drive the corresponding straight section to move, each bent section is located on the side of the driven roller away from the support plate, and rollers are provided on the top of the side facades of the two bent sections that are close to each other, and each roller is rotatably connected to the corresponding bent section;
[0018] Each of the driven pulleys has a first pulley on the side away from the conveyor belt, and each first pulley is fixedly connected to the corresponding driven roller; each of the two straight sections has a second pulley on the side surfaces away from each other, each second pulley is rotatably connected to the corresponding straight section, each second pulley is a double-row pulley, and each second pulley is connected to the corresponding first pulley in a transmission manner through a first synchronous belt;
[0019] A third pulley is fixedly installed on the mutually distant side surfaces of the two bending sections. Each third pulley is rotatably connected to the corresponding bending section. Each third pulley is connected to the corresponding second pulley via a second synchronous belt in a transmission manner. Furthermore, each third pulley is fixedly connected to the corresponding idler roller.
[0020] Through the above technical solution, by setting up the idler rollers, during the conveying of the ton bag, the idler rollers are adjusted to press against the surface of the ton bag, which can play a role in pressing the bag roll, preventing the bag roll from loosening, and thus avoiding the initial deviation of the ton bag conveying, thereby reducing the subsequent workload and improving efficiency.
[0021] By setting up the swing arm and the first cylinder, the position of the swing arm can be adjusted by extending and retracting the output shaft in the first cylinder, which in turn can adjust the position of the idler roller on the swing arm. This ensures that the outer curved surface of the idler roller can abut against the surface of the ton bag, providing support and limiting for the conveying of the ton bag, thereby ensuring the stable delivery of the ton bag.
[0022] Furthermore, the support frame also includes two second support columns with identical structures, the two second support columns are arranged on opposite sides, and each second support column is arranged on the same side as the corresponding first support column, and a second connecting beam is fixedly arranged between the tops of the two second support columns;
[0023] A separation mechanism for separating two layers of film in a ton bag is provided on the support frame above the support plate. The separation mechanism includes a fourth cylinder, a second fixing member, and a third fixing member. The fourth cylinder is fixedly mounted on the second connecting beam. The second fixing member is fixedly connected to the output shaft of the fourth cylinder. Multiple first pneumatic suction cups are provided on the second fixing member. Each first pneumatic suction cup is connected to a first air pipe. A strip-shaped notch penetrating the support plate is provided. The strip-shaped notch corresponds to the position of the first pneumatic suction cup. The third fixing member is fixedly mounted on the support frame below the support plate. Multiple second pneumatic suction cups are provided on the third fixing member. Each second pneumatic suction cup is connected to a second air pipe. Each second pneumatic suction cup corresponds to the position of one of the first pneumatic suction cups.
[0024] When the fourth cylinder drives the second fixing member to move multiple first pneumatic suction cups downwards and press against the corresponding second pneumatic suction cup, each first pneumatic suction cup is located between the position detection photoelectric sensor and the positioning bag opening photoelectric sensor.
[0025] Through the above technical solution, by setting up multiple first pneumatic suction cups and multiple second pneumatic suction cups, each first pneumatic suction cup can adsorb the upper film in the ton bag, and each second pneumatic suction cup can adsorb the lower film in the ton bag, thereby improving the separation effect of the two films in the ton bag and ensuring subsequent production.
[0026] Furthermore, it also includes two rope-pulling mechanisms, each mounted on one of the second support columns. The two rope-pulling mechanisms have the same structure. Each rope-pulling mechanism includes a rotating shaft and a pneumatic motor. Each pneumatic motor is fixedly mounted on the second support column. The output shaft of each pneumatic motor is fixedly connected to the corresponding rotating shaft. The length direction of each rotating shaft is set along the conveying direction of the conveying mechanism. Two limiting plates are concentrically fixed on each transmission shaft.
[0027] Two through holes are provided on the side of the support plate away from the conveying mechanism. Each through hole extends through the thickness direction of the support plate. A lip-shaped sealing ring is provided on each through hole. A rope-retracting screw is provided on the support frame below each through hole. Each rope-retracting screw is arranged along the conveying direction of the conveying mechanism.
[0028] With the above technical solution, by setting up two rope-pulling mechanisms, two ropes can be set on one side of each layer of the ton bag in the whole roll, and the two ropes are fixed on two drive shafts. During the process of the conveyor belt conveying the ton bag, the pneumatic motor drives the drive shaft, and each rope is also continuously wound, thereby ensuring the conveying effect of the ton bag.
[0029] Furthermore, a support mechanism is provided on the support frame corresponding to the conveying starting point of the conveying mechanism. The support mechanism includes an unwinding shaft and two tilting arms. The lower ends of the two tilting arms are rotatably connected to the support frame. The unwinding shaft is located between the two tilting arms, and both ends of the unwinding shaft are detachably connected to the corresponding tilting arm. Two chucks are spaced apart on the unwinding shaft, and each chuck is detachably connected to the unwinding shaft. The unwinding shaft between the two chucks is used to mount the entire roll of ton bag.
[0030] The support frame includes two identical first support columns, which are respectively disposed on both sides of the conveyor belt in the width direction.
[0031] Each of the first support columns has a second cylinder fixedly installed on its side face away from the conveying mechanism, and the output shaft of each second cylinder is fixedly connected to the corresponding tilting arm.
[0032] A first connecting beam is fixedly installed between the tops of the two first support columns. Two third cylinders with identical structures are installed on the first connecting beam. The output shaft of each third cylinder is fixedly connected to both sides of the conveyor frame in the width direction.
[0033] One of the first support columns is equipped with a first manual valve, a second manual valve, and a pressure regulating valve. The first manual valve and the pressure regulating valve are connected. The first manual valve is used to control the third cylinder, and the second manual valve is used to control the second cylinder.
[0034] The above technical solution, through the setting of the third cylinder, ensures that the conveyor belt is always in contact with the ton bag, increases the bag feeding friction, and prevents the ton bag from shifting due to looseness at the beginning of the conveying process, thereby improving the efficiency of the subsequent ton bag separation process.
[0035] With the setting of the first manual valve and the pressure regulating valve, the user can manually adjust the operating status of the conveying mechanism according to the actual operating needs. The user can precisely control the air pressure value of the conveying mechanism through the pressure regulating valve. When adjusting the angle of the bag feeding mechanism, the conveyor belt is always in close contact with the ton bag roll, which prevents the ton bag from shifting due to the initial looseness of the ton bag during feeding. It also prevents the conveyor belt from being too tightly attached to the ton bag roll due to excessive pressure of the third cylinder, which would increase the load on the conveyor and affect the life of the conveyor motor. This ensures that the power output during the conveying process is stable and adjustable.
[0036] By setting up a second cylinder and a second manual valve, when changing a full roll of ton bags, the extension of the second cylinder can be adjusted by the second manual valve, and then the position of the two tilting arms can be adjusted so that the top of the two tilting arms gradually lowers, making it easier for users to change ton bags, thereby reducing the difficulty of changing ton bags and speeding up the replacement rate.
[0037] Furthermore, it also includes a forklift component fixedly mounted on the support frame. The forklift component includes two hollow square tubes and multiple lifting components fixedly mounted on the support frame. The two hollow square tubes are spaced apart at the bottom of both sides of the center of the support frame, and the two lifting components are spaced apart on both sides of the center of the support frame, and are respectively located on both sides of the width direction of the conveying mechanism.
[0038] Through the above technical solution, and with the forklift attachment, when users have lifting equipment, they can easily lift and transfer the equipment using the two dedicated lifting attachments provided on the equipment. For users with forklifts, the forklifts can directly insert the forklift attachments to quickly and smoothly lift and transfer the equipment. This dual transfer method design not only meets the usage needs of different users in different scenarios, but also greatly improves the versatility and flexibility of the equipment, thereby significantly improving work efficiency and bringing users a more convenient and efficient user experience.
[0039] The above solution has the following advantages:
[0040] 1. Through the automatic correction mechanism, six photoelectric sensors in three groups can detect the position of the bag opening on the support plate. When the detection finds that the position of the bag opening has deviated, the appropriate drive component is selected to push the push plate to adjust the position of the bag opening according to the position of the bag opening deviation, thereby adjusting the position of the bag opening to the correct position. This will facilitate the subsequent separation of the bag opening, thereby speeding up the work efficiency and ensuring the separation quality of the bag opening.
[0041] 2. By setting up the photoelectric sensor for bag opening, it is possible to detect whether the position of the bag opening has been adjusted correctly, thereby ensuring that the separation mechanism is started accurately to separate the bag opening, thus ensuring the accuracy and quality of the separation action.
[0042] 3. By setting the first pulley, the driven roller can synchronously drive the first pulley to rotate when it rotates. The first pulley drives the second pulley to rotate synchronously through the first synchronous belt. After the second pulley rotates, it drives the third pulley to rotate through the second synchronous belt. After the third pulley rotates, it drives the idler roller to rotate, thereby providing a conveying action from the other side of the ton bag, improving the conveying effect of the ton bag, and thus speeding up the efficiency of ton bag delivery.
[0043] 4. By setting up the idler rollers, during the conveying of the ton bags, adjusting the idler rollers to press against the surface of the ton bags can effectively compress the bag roll, preventing it from becoming loose and thus avoiding initial deviation during ton bag conveying. This reduces subsequent workload and improves efficiency. The swing arm and first cylinder, through the extension and retraction of the output shaft in the first cylinder, adjust the position of the swing arm, which in turn adjusts the position of the idler rollers on the swing arm. This ensures that the outer curved surface of the idler rollers presses against the surface of the ton bags, providing support and limiting for the conveying of the ton bags, thereby ensuring stable ton bag feeding.
[0044] 5. When the ton bag is running on the conveyor belt, the guard plate can accurately limit and guide it, and help correct the ton bag's deviation. This ensures that when the ton bag is conveyed to the support plate, it can arrive at a precise and stable position, which greatly reduces the possibility of difficulty in opening the bag or failure to open the bag due to position deviation, thereby improving the efficiency of opening difficulties or failures.
[0045] 6. By setting up multiple first pneumatic suction cups and multiple second pneumatic suction cups, each first pneumatic suction cup can adsorb the upper film in the ton bag, and each second pneumatic suction cup can adsorb the lower film in the ton bag, thereby improving the separation effect of the two films in the ton bag and ensuring subsequent production.
[0046] 7. By setting up two rope-pulling mechanisms, two ropes can be set on one side of each layer of ton bags in the whole roll, and the two ropes are fixed on two drive shafts. During the process of the conveyor belt conveying the ton bags, the pneumatic motor drives the drive shafts, and each rope is also continuously wound, thus ensuring the conveying effect of the ton bags.
[0047] 8. The third cylinder ensures the conveyor belt remains in contact with the ton bag, increasing friction during bag feeding and preventing initial bag shift due to looseness, thus improving efficiency in subsequent bag separation. The first manual valve and pressure regulating valve allow users to manually adjust the conveyor's operating status according to actual needs. The pressure regulating valve precisely controls the air pressure, ensuring the conveyor belt remains in contact with the ton bag roll during adjustment. This prevents initial bag shift due to looseness and avoids excessive pressure from the third cylinder, which could increase the load on the conveyor and affect the motor's lifespan. This ensures stable and adjustable power output during the conveying process.
[0048] By setting up a second cylinder and a second manual valve, when changing a full roll of ton bags, the extension of the second cylinder can be adjusted by the second manual valve, and then the position of the two tilting arms can be adjusted so that the top of the two tilting arms gradually lowers, making it easier for users to change ton bags, thereby reducing the difficulty of changing ton bags and speeding up the replacement rate.
[0049] 9. With the forklift attachment, when users have lifting equipment, they can easily lift and transfer the equipment using the two dedicated lifting attachments provided with the equipment. For users with forklifts, the forklift can directly insert the forklift attachment to quickly and smoothly lift and transfer the equipment. This dual transfer method design not only meets the usage needs of different users in different scenarios, but also greatly improves the versatility and flexibility of the equipment, thereby significantly improving work efficiency and bringing users a more convenient and efficient user experience.

[0062] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0063] In a specific embodiment, such as Figures 1-10 As shown, the bag feeding structure of the fully automatic ton bag machine includes a support frame 1, a conveying mechanism for conveying ton bags, a support plate 2 on the support frame 1 corresponding to the end point of the conveying mechanism, and an automatic correction mechanism 3 on the support frame 1. The automatic correction mechanism 3 includes a detection component 301 and an execution component 302.
[0064] The detection component 301 is disposed at the bottom of the support plate 2. The detection component 301 includes no less than three sets, each set of which includes two position detection photoelectric sensors 4. The three sets of detection components are arranged symmetrically in a straight line around the center of the width direction of the support plate 2, forming a two-layer surrounding structure with the first set of detection components as the center. The width between the two position detection photoelectric sensors 4 in the second set of detection components is the width of the ton bag. Each position detection photoelectric sensor 4 is provided with a first through hole 52 on the support plate 2. In this specific embodiment, the detection component 301 is provided with three sets, for a total of six position detection photoelectric sensors 4. Each first through hole 52 is an oblong hole, which can be applied to ton bags of different widths.
[0065] The execution component 302 includes two push plates 3021 respectively disposed at the end point of the conveying mechanism in the width direction. The two push plates 3021 are symmetrically disposed along the center line of the width direction in the conveying mechanism. Each push plate 3021 is slidably engaged with the conveying mechanism. Two drive components 3022 are fixedly disposed on the conveying mechanism for driving the two push plates 3021 to move.
[0066] When the detection component 301 detects a positional shift in the opening of the ton bag, the drive component 3022, which is closer to the ton bag in the width direction of the conveying mechanism, drives the corresponding push plate 3021 to move and push the ton bag, so that the opening of the ton bag is in the middle position of the conveying mechanism.
[0067] The three sets of six-position photoelectric sensors 4 can detect the position of the bag opening on the support plate 2. When the detection finds that the position of the bag opening has shifted, the appropriate drive component 3022 is selected to push the push plate 3021 to adjust the position of the bag opening according to the position of the shift. This will adjust the position of the bag opening to the correct position, which will facilitate the subsequent separation of the bag opening, thereby speeding up the work efficiency and ensuring the separation quality of the bag opening.
[0068] A support mechanism is provided on the support frame 1 corresponding to the starting point of the conveying mechanism. The support mechanism includes an unwinding shaft 6 and two tilting arms 7. The lower ends of the two tilting arms 7 are rotatably connected to the support frame 1. The unwinding shaft 6 is located between the two tilting arms 7, and both ends of the unwinding shaft 6 are detachably connected to the corresponding tilting arms 7. Two chucks 9 are spaced apart on the unwinding shaft 6. Each chuck 9 is detachably connected to the unwinding shaft 6. The unwinding shaft 6 between the two chucks 9 is used to fit the whole roll of ton bag.
[0069] The unwinding shaft 6 has fixed rods 8 at both ends along its length, and the outer periphery of the two fixed rods 8 is set in a regular polygon shape. The end of the fixed rod 8 away from the unwinding shaft 6 along its length is provided with threads. The two chucks 9 are threadedly connected to the threaded section of the fixed rod 8. The two chucks 9 are fixedly provided with handles 10 on their mutually distant side surfaces.
[0070] Each flipping arm 7 is fixedly provided with a support shaft seat 11 at its top. Each support shaft seat 11 is hollow. Opening clamps 12 are fixedly provided on the side surfaces of the two support shaft seats 11 that are close to each other. Each opening clamp 12 has a hollow fixed plate 13 at one end away from the corresponding support shaft seat 11. Each support shaft seat 11 has a connector 14 in the hollow section. The other end of each connector 14 extends into the hollow section of the corresponding fixed plate 13. Each connector 14 has a first notch on the section of the connector 14 located on the corresponding fixed plate 13. The other ends of the two fixing rods 8 are adapted to be placed in the corresponding first notch. In this specific embodiment, the opening clamp 12 is a leather cup.
[0071] Each time a roll of ton bags is replaced, simply press and hold the fixing plate 13 and manually pry it open. At this time, the opening clamp 12 is compressed, and the user can remove the fixing rod 8 from the first notch. Similarly, when installing a new roll of ton bags, simply pry the fixing plate 13 open again to compress the opening clamp 12 and then insert the fixing rod 8 into the first notch. This speeds up the installation and removal of the roll of ton bags, thereby increasing bag feeding efficiency. Users can adjust the position of the two chucks 9 by turning them separately, thereby quickly achieving the limiting and fixing effect of the roll of ton bags. The structure is simple and the operation is quick, thus speeding up bag feeding efficiency. The handle 10 allows the operator to easily rotate the chucks 9. The structure is simple and easy to operate, thereby speeding up the rotation of the chucks 9, thus speeding up bag feeding efficiency and reducing labor costs. After inserting the square-shaped fixing rod 8 into the first notch, the unwinding shaft 6 will not rotate, thus preventing the roll of ton bags from rotating. The simple structure ensures the stability of the roll of ton bags after installation.
[0072] Two positioning and opening photoelectric sensors 5 are also provided on the bottom side of the support plate 2 away from the position detection photoelectric sensor 4. Each of the two positioning and opening photoelectric sensors 5 has a second through hole on the support plate 2. The positioning and opening photoelectric sensor 5 can detect whether the position of the bag opening of the ton bag has been adjusted correctly, thereby ensuring that the separation mechanism is started accurately to separate the bag opening of the ton bag, thus ensuring the accuracy and quality of the separation action.
[0073] Two first mounting members 53 are fixedly installed on the support frame 1. The two first mounting members 53 are respectively installed on the support frames 1 on both sides of the width direction in the conveying mechanism. Each drive component 3022 is fixedly installed on the corresponding first mounting member 53, and the output shaft of each drive component 3022 is fixedly connected to the corresponding push plate 3021. Each push plate 3021 is slidably connected to the corresponding first mounting member 53. Each drive component 3022 is used to drive the corresponding push plate 3021 to move toward or away from the ton bag conveyed on the conveying mechanism. After the ton bag is deviated, the drive component 3022 starts to push the push plate 3021 toward the ton bag. The push plate 3021 pushes the ton bag to adjust the position of the ton bag, thereby achieving the accuracy of the ton bag position and ensuring the accuracy and separation quality of subsequent separation actions.
[0074] The conveying mechanism includes a conveyor frame 15, a conveyor belt 16, and a drive motor 17. The conveyor frame 15 is inclined and mounted on the support frame 1, with the end of the conveyor frame 15 closer to the support plate 2 being higher than the end farther from the support plate 2. On both sides of the width direction of the end of the conveyor frame 15 closer to the support plate 2, there are drive wheels 18, which are connected by a drive roller. One of the drive wheels 18 is fixedly connected to the output shaft of the drive motor 17. On both sides of the width direction of the end of the conveyor frame 15 farther from the support plate 2, there are driven wheels 19, which are connected by a driven roller. The driven roller is connected to the drive roller via the conveyor belt 16 in a transmission manner. The conveyor belt 16 has a width... Guard plates 20 are respectively installed on the conveyor belts 16 on both sides of the direction. The bottom of each guard plate 20 has a gap with the top of the conveyor belt 16. The length of each guard plate 20 is set along the conveying direction of the conveying mechanism. The conveyor frame 15 corresponding to the two guard plates 20 that are far apart from each other is respectively provided with adjusting parts 21 for adjusting the corresponding guard plate 20. When the ton bag is running on the conveyor belt 16, the guard plate 20 can accurately limit and guide it and help correct the ton bag deviation. This ensures that when the ton bag is conveyed to the support plate 2, it can arrive at a precise and stable position, which greatly reduces the possibility of difficulty in opening the bag or failure in opening the bag due to position deviation, thereby improving the efficiency of opening difficulty or failure in opening the bag.
[0075] The conveying mechanism has roller assemblies on both sides of the width direction at the starting point of the conveying mechanism. Each roller assembly includes a roller bracket 22, a swing arm 23, and a first cylinder 24. Each roller bracket 22 is mounted on a corresponding conveying frame 15, and each first cylinder 24 is fixedly mounted on the corresponding roller bracket 22. Each swing arm 23 includes an integrally formed straight section and a bent section. Each first cylinder 24 is used to drive the corresponding straight section to move. Each bent section is located on the side of the driven roller away from the support plate 2. Rollers 25 are provided on the top of the adjacent side facades of the two bent sections, and each roller 25 is rotatably connected to the corresponding bent section. A first pulley 26 is provided on the side of each driven wheel 19 away from the conveyor belt 16, and each first pulley 26 is fixedly connected to the corresponding driven roller. Second pulleys 27 are provided on the adjacent side facades of the two straight sections, and each second pulley 27 is rotatably connected to the corresponding straight section. Each second pulley 27 is in double rows. Each second pulley 27 is connected to its corresponding first pulley 26 via a first synchronous belt 28 in a transmission manner. A third pulley 29 is fixedly installed on the mutually distant side surfaces of the two bent sections. Each third pulley 29 is rotatably connected to its corresponding bent section, and each third pulley 29 is connected to its corresponding second pulley 27 via a second synchronous belt 30 in a transmission manner. Each third pulley 29 is also fixedly connected to its corresponding idler roller 25. During the conveying of the ton bag, adjusting the idler roller 25 to press against the surface of the ton bag helps to tighten the bag roll, preventing it from shifting due to loosening and thus avoiding initial deviation during ton bag conveying, thereby reducing subsequent workload and improving efficiency. The position of the swing arm 23 is adjusted by extending and retracting the output shaft in the first cylinder 24, which in turn adjusts the position of the idler roller 25 on the swing arm 23. This ensures that the outer curved surface of the idler roller 25 presses against the surface of the ton bag, providing support and limiting for ton bag conveying, thereby ensuring stable ton bag feeding.
[0076] When the driven roller rotates, it can synchronously drive the first pulley 26 to rotate. The first pulley 26 drives the second pulley 27 to rotate synchronously through the first synchronous belt 28. After the second pulley 27 rotates, it drives the third pulley 29 to rotate through the second synchronous belt 30. After the third pulley 29 rotates, it drives the idler roller 25 to rotate, thereby providing a conveying action from the other side of the ton bag, improving the conveying effect of the ton bag, and thus speeding up the efficiency of ton bag delivery.
[0077] The support frame 1 includes two identical first support columns 31, which are respectively located on both sides of the conveyor belt 16 in the width direction. A second cylinder 32 is fixedly installed on the side of each first support column 31 away from the conveying mechanism, and the output shaft of each second cylinder 32 is fixedly connected to the corresponding tilting arm 7. A first connecting beam 33 is fixedly installed between the tops of the two first support columns 31, and two identical third cylinders 34 are installed on the first connecting beam 33. The output shaft of each third cylinder 34 is fixedly connected to both sides of the conveyor frame 15 in the width direction. The installation of the third cylinders 34 ensures that the conveyor belt 16 is always in contact with the ton bag, increasing bag feeding friction and preventing the ton bag from shifting due to looseness at the beginning of the conveying process, thereby improving the efficiency of the subsequent ton bag separation process.
[0078] One of the first support columns 31 is equipped with a first manual valve 47, a second manual valve 48 and a pressure regulating valve 49. The first manual valve 47 and the pressure regulating valve 49 are connected. The first manual valve 47 is used to control the third cylinder 34, and the second manual valve 48 is used to control the second cylinder 32.
[0079] Users can manually adjust the operating status of the conveying mechanism through the first manual valve 47 according to actual operating needs. Users can precisely control the air pressure value of the conveying mechanism through the pressure regulating valve 49. When adjusting the angle of the bag feeding mechanism, the conveyor belt 16 is always in close contact with the ton bag roll to prevent the ton bag from shifting due to the initial looseness of the ton bag during bag feeding. It also prevents the conveyor belt from being too tightly attached to the ton bag roll due to excessive pressure from the third cylinder 34, which would increase the load on the conveyor and affect the life of the conveyor motor. This ensures that the power output during the conveying process is stable and adjustable.
[0080] By setting the second cylinder 32 and the second manual valve 48, when changing a whole roll of ton bag, the extension of the second cylinder 32 can be adjusted by the second manual valve 48, and then the position of the two tilting arms 7 can be adjusted so that the top of the two tilting arms 7 gradually lowers, which makes it easier for users to change the ton bag, thereby reducing the difficulty of changing the ton bag and speeding up the replacement rate.
[0081] The support frame 1 also includes two identical second support columns 35, which are arranged opposite each other, and each second support column 35 is arranged on the same side as the corresponding first support column 31. A second connecting beam 36 is fixedly arranged between the tops of the two second support columns 35. A separation mechanism for separating the two layers of film in the ton bag is provided on the support frame 1 above the support plate 2. The separation mechanism includes a fourth cylinder 37, a second fixing member 38, and a third fixing member 39. The fourth cylinder 37 is fixedly arranged on the second connecting beam 36. The second fixing member 38 and the output shaft of the fourth cylinder 37 are fixedly connected. A plurality of first pneumatic suction cups 40 are provided on the second fixing member 38. Each suction cup 40 is connected to a first air pipe. A strip-shaped notch is provided on the support plate 2, and the strip-shaped notch corresponds to the position of the first pneumatic suction cup 40. The third fixing member 39 is fixedly installed on the corresponding support frame 1 below the support plate 2. Multiple second pneumatic suction cups 41 are provided on the third fixing member 39. Each second pneumatic suction cup 41 is connected to a second air pipe, and each second pneumatic suction cup 41 corresponds to the position of a first pneumatic suction cup 40. When the fourth cylinder 37 drives the second fixing member 38 to move multiple first pneumatic suction cups 40 downward and press against the corresponding second pneumatic suction cup 41, each first pneumatic suction cup 40 is located between the correction photoelectric and the positioning bag opening photoelectric 5.
[0082] Each first pneumatic suction cup 40 can adsorb the upper film layer in the ton bag, and each second pneumatic suction cup 41 can adsorb the lower film layer in the ton bag, thereby improving the separation effect of the two films in the ton bag and ensuring subsequent production.
[0083] The bag feeding structure of the fully automatic ton bag machine also includes two rope pulling mechanisms, each set on one of the second support columns 35. The two rope pulling mechanisms have the same structure. Each rope pulling mechanism includes a rotating shaft 42 and a pneumatic motor 43. Each pneumatic motor 43 is fixedly set on the second support column 35. The output shaft of each pneumatic motor 43 is fixedly connected to the corresponding rotating shaft 42. The length direction of each rotating shaft 42 is set along the conveying direction of the conveying mechanism. Two limit plates 44 are concentrically fixed on each drive shaft.
[0084] Two through holes are provided on the side of the support plate 2 away from the conveying mechanism. Each through hole penetrates the thickness direction of the support plate 2. A lip seal ring 45 is provided on each through hole. A lip seal ring 46 is provided on the corresponding support frame 1 below each through hole. Each lip seal ring 46 is set along the conveying direction of the conveying mechanism. Two ropes are provided on one side of each layer of the ton bag in the whole roll, and the two ropes are fixed on two drive shafts. During the process of the conveyor belt 16 conveying the ton bag, the pneumatic motor 43 drives the drive shaft, and each rope is also continuously wound, thereby ensuring the conveying effect of the ton bag.
[0085] The bag-feeding structure of the fully automatic ton bag machine also includes a forklift assembly fixedly mounted on the support frame 1. The forklift assembly comprises two hollow square tubes 50 and multiple lifting components 51 fixedly mounted on the support frame 1. The two hollow square tubes 50 are spaced apart at the bottom of the center sides of the support frame 1, and the two lifting components 51 are spaced apart on both sides of the center of the support frame 1, respectively positioned on both sides of the width direction of the conveying mechanism. With the forklift assembly, when a user has lifting equipment, they can easily lift and transfer the equipment using the two dedicated lifting components 51. For users with forklifts, the forklift can directly insert into the forklift assembly to quickly and smoothly lift and transfer the equipment. This dual-transfer design not only meets the needs of different users in different scenarios but also greatly improves the versatility and flexibility of the equipment, thereby significantly improving work efficiency and providing users with a more convenient and efficient user experience.
[0086] Operating Procedure: The second cylinder starts, driving the two tilting arms to rotate until they reach an angle convenient for the user to operate on the unwinding shaft. The fixed plate is then moved to remove the unwinding shaft from the first notch, and one of the chucks on the corresponding side is removed. The entire roll of ton bag is then placed onto the unwinding shaft. The removed chuck is reinstalled, and the unwinding shaft is reinstalled into the first notch. At this point, the chucks are manually turned to adjust their positions, so that one end of each chuck is positioned relative to the entire roll of ton bag. After turning the chucks, the fastening bolts are tightened on the unwinding shaft corresponding to the side of the two chucks that is furthest apart. The entire roll of ton bag is then placed onto the unwinding shaft. Two ropes, wound around the bag, are pulled along the conveyor belt and bag-placement plate, passing through the corresponding two first through holes and then tied to the corresponding conveyor shaft. At this time, all structures are activated. When the ton bag leaves the roll of ton bags and enters the conveyor belt, the first cylinder pushes the swing arm to rotate, so that the roller on the swing arm abuts against the side of the ton bag. Then, the ton bag is gradually moved closer to the support plate by the conveyor belt. After the ton bag enters the support plate, two sets of correction photoelectric sensors begin to detect the ton bag opening. When the position of the ton bag opening is found to be off, two sets of automatic correction mechanisms are activated, and the push plate is pushed by the drive component to adjust the position of the ton bag opening.
