Description

Technical Field

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

[0002] In the existing technology, packaging bag processing equipment forms individual packaging bags by cutting and hot-pressing them during processing. In order to stack the packaging bags better, a bag sorting machine is needed to stand up the horizontally transported packaging bags so that multiple bags can be stacked. However, maintaining their continuous stacking and preventing the packaging bags from falling over is a challenge that needs to be overcome. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a packaging bag sorting machine, which adopts the movable cooperation of the storage plate and the abutment, so that the stacked packaging bags can be abutted to prevent them from tipping over, and does not affect the normal backward movement of the pusher plate. Its stacking stability structure is reasonably laid out.

[0004] This utility model discloses a packaging bag sorting machine, including a frame, which includes a conveying station, a stacking station and a bag pushing station. The conveying station is characterized by having a first conveyor belt and a second conveyor belt, which are partially joined together to form a packaging bag clamping section for clamping and transporting packaging bags. The packaging bag clamping section is partially tilted and extends above the bag pushing station. The first conveyor belt has a feeding section at the other end of the packaging bag clamping section for transporting packaging bags to the packaging bag clamping section.

[0005] The stacking station is equipped with a storage plate and abutment components. The storage plate is guided and slid on the frame in the front-to-back direction. The frame is also equipped with a retaining component for keeping the storage plate pressed against the abutment components. The abutment components include side abutment components and top abutment components. The side abutment components are provided with a squeezing surface for squeezing the sides of the packaging bag to align them. There are two sets of side abutment components that slide laterally on the frame. The frame is also equipped with a first driving component for driving the two sets of side abutment components to slide towards or away from each other. The top abutment components are lifted and lowered on the frame. The frame is also equipped with a second driving component for driving the top abutment components to lift and lower.

[0006] The bag pushing station is equipped with a bag pushing plate and a third driving component that drives the bag pushing plate to slide back and forth. When the top edge abutment descends, the third driving component can drive the bag pushing plate out of the stacking station.

[0007] Using the above technical solution, during use, the packaging bag can be transported to the packaging bag clamping section through the feeding section of the first conveyor belt. Because the packaging bag clamping section is partially tilted and extends above the bag pushing station, the packaging bag will be in an upright state after being transported through the packaging bag clamping section and will eventually fall in front of the bag pushing plate. At this time, the third drive component on the bag pushing station drives the bag pushing plate to move forward. When it is about to pass the side abutment and the top abutment, the first drive component drives the side abutment to separate, and the second drive component drives the top abutment to rise, so that the bag pushing plate pushes the packaging bag to the stacking station and presses it onto the storage plate. At this time, the second drive component drives the top abutment to reset. At the same time, due to the function of the holding component, the storage plate will press the packaging bag onto the top abutment. Furthermore, the bag pushing plate can be directly retracted, and the first drive component drives the side abutment to reset and squeeze the side of the stacked packaging bag, thereby making it neat, which can facilitate subsequent bundling and increase the abutment area.

[0008] A further detail of this invention: The first drive assembly includes a first drive motor, a first eccentric wheel, and a first connecting rod. The side abutment slides laterally on the frame. The first eccentric wheel is linked to the output shaft of the first drive motor. One end of the first connecting rod is hinged to the side abutment, and the other end is linked to the first eccentric wheel. The second drive assembly includes a second drive motor, a second eccentric wheel, and a second connecting rod. The top abutment slides vertically on the frame. The second eccentric wheel is linked to the output shaft of the second drive motor. One end of the second connecting rod is hinged to the top abutment, and the other end is linked to the second eccentric wheel.

[0009] The above technical solution involves a relatively high energy consumption during the production of packaging bags. The first and second drive components use motors, eccentric wheels, and connecting rods, which can significantly reduce energy consumption compared to cylinder-driven systems, thus aligning with the concept of sustainable development.

[0010] A further feature of this invention is that the retaining assembly includes a fixed pulley and a counterweight on the frame, and a hanging rope is provided on the storage plate, with the hanging rope passing through the fixed pulley and connected to the counterweight.

[0011] Using the above technical solution, the counterweight moves downward by gravity and can pull the storage plate by pulling the rope, so that the storage plate always has a backward force, thus pressing the stacked packaging bags against the abutment.

[0012] A further feature of this invention is that a lifting platform and a lifting drive component for driving the lifting platform to move up and down are provided on the frame at the stacking station, and a counting sensor for detecting the number of packaging bags falling is also provided on the frame.

[0013] Using the above technical solution, when the counting sensor detects the corresponding number of bags passing by, the lifting drive unit drives the lifting platform to rise, thereby raising the packaging bags at the corresponding positions. At this time, employees can take out the corresponding packaging bags according to the raised positions and tie them up. With intelligent counting, employees do not need to keep an eye on the number of bags falling, making it more convenient to use. One employee can work with multiple machines.

[0014] A further feature of this invention is that a baffle plate is rotatably mounted on the frame at the position corresponding to the side abutment, and a sensing sensor is mounted on the frame at the position corresponding to the baffle plate.

[0015] By adopting the above technical solution, the use of a baffle can prevent employees from putting their hands into the bag pushing station during operation. When the baffle rotates and is lowered, it can trigger the sensor, thereby stopping the machine from working. This not only improves safety performance but also makes it easier for employees to handle malfunctions. Attached Figure Description

[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] This utility model discloses a packaging bag sorting machine, including a frame 1. The frame 1 includes a transmission station 2, a stacking station 3, and a bag pushing station 4. In an embodiment of this utility model, the transmission station 2 is provided with a first conveyor belt 21 and a second conveyor belt 22. The first conveyor belt 21 and the second conveyor belt 22 are partially attached to form a packaging bag clamping section 23 for clamping and transporting packaging bags. The packaging bag clamping section 23 is partially tilted and extends above the bag pushing station 4. The first conveyor belt 21 is provided with a feeding section 211 at the other end of the packaging bag clamping section 23 for transporting packaging bags to the packaging bag clamping section 23.

[0028] The stacking station 3 is equipped with a storage plate 31 and abutment 32. The storage plate 31 is guided and slidably moved on the frame 1 in the front-back direction. The frame 1 is also equipped with a retaining assembly for keeping the storage plate 31 pressed against the abutment 32. The abutment 32 includes a side abutment 321 and a top abutment 322. The side abutment 321 is provided with a squeezing surface 3211 for squeezing the side of the packaging bag to align it (preferably, the side abutment 321 is provided with an L-shaped squeezing plate, which can squeeze the packaging bag). The side abutment can also serve as a rear support, and the side abutment 321 is preferably adjustable in the vertical direction (and can be locked with bolts after adjustment). The side abutment 321 includes two sets that slide laterally on the frame 1. The frame 1 is also provided with a first drive assembly 6 for driving the two sets of side abutment 321 to slide towards or away from each other. The top abutment 322 is lifted and lowered on the frame 1. The frame 1 is also provided with a second drive assembly 7 for driving the top abutment 322 to lift and lower.

[0029] The bag pushing station 4 is equipped with a bag pushing plate 41 and a third driving component 42 that drives the bag pushing plate 41 to slide back and forth. When the top edge abutment 322 descends, the third driving component 42 can drive the bag pushing plate 41 out of the stacking station (the top edge abutment 322 can descend to the lowest position and still be higher than the bag pushing plate 41, or the top edge abutment 322 can be provided with a clearance area). Preferably, the bag can be detected by a sensor, and then the third driving component 42 can drive the bag pushing plate 41 to work. The third driving component 42 is preferably driven by a synchronous belt to drive the bag pushing plate 41 to move. Of course, it can also be driven by a cylinder or an electric cylinder.

[0030] Using the above technical solution, during use, the packaging bag can be transported to the packaging bag clamping section 23 via the feeding section 211 on the first conveyor belt 21. Because the packaging bag clamping section 23 is partially tilted and extends above the bag pushing station 4, the packaging bag will be in an upright state after being transported by the packaging bag clamping section 23 and will eventually fall in front of the bag pushing plate 41. At this time, the third drive component 42 on the bag pushing station 4 drives the bag pushing plate 41 to move forward. When it is about to pass the side abutment 321 and the top abutment 322, the first drive component 6 drives the side abutment 321 to separate. When the second drive assembly 7 drives the top edge abutment 322 to rise, the pusher plate 41 pushes the packaging bag to the stacking station 3 and presses it onto the storage plate 31. At this time, the second drive assembly 7 drives the top edge abutment 322 to reset. At the same time, due to the function of the holding assembly, the storage plate 31 will press the packaging bag onto the top edge abutment 322. Furthermore, the pusher plate 41 can be directly retracted, and the first drive assembly 6 drives the side abutment 321 to reset and squeeze the side of the stacked packaging bag, thereby straightening the edge, which can facilitate later bundling and increase the abutment area.

[0031] The first drive assembly 6 includes a first drive motor 61, a first eccentric wheel 62, and a first connecting rod 63. The side abutment 321 slides laterally on the frame 1. The first eccentric wheel 62 is linked to the output shaft of the first drive motor 61. One end of the first connecting rod 63 is hinged to the side abutment 321, and the other end is linked to the first eccentric wheel 62 (the connection between the first connecting rod 63 and the first eccentric wheel 62 can be through an eccentric shaft or by directly sleeved on the first eccentric wheel 62). The second drive assembly 7 includes a second drive motor 71, a second eccentric wheel 72, and a second connecting rod 73. The top abutment 322 slides vertically on the frame 1. The second eccentric wheel 72 is linked to the output shaft of the second drive motor 71. One end of the second connecting rod 73 is hinged to the top edge abutment 322, and the other end is linked to the second eccentric wheel 72. The packaging bag manufacturing process itself consumes a lot of energy. The first drive assembly 6 and the second drive assembly 7 use a motor, eccentric wheel and connecting rod, which can reduce a lot of energy consumption compared with the cylinder drive, which is in line with the concept of sustainable development. Of course, the first drive assembly 6 and the second drive assembly 7 can also be driven by an electric cylinder or a pneumatic cylinder, but the corresponding energy consumption will increase. The guide sliding of the top edge abutment 322 can be achieved by the cooperation of a guide block and a guide rail, or by the use of a guide hole and a guide rod.

[0032] The retaining assembly includes a fixed pulley 5 and a counterweight on the frame 1. The storage plate 31 is provided with a hanging rope (the counterweight and hanging rope are not shown in the figure. The counterweight and hanging rope are common knowledge and do not involve material or structural innovation, so they will not be described in detail here). The hanging rope passes through the fixed pulley 5 and is connected to the counterweight. The counterweight moves downward by gravity and can pull the storage plate 31 by pulling the rope, so that the storage plate 31 always has a backward force, thereby pressing the stacked packaging bags against the abutment 32. Of course, the retaining assembly can also be a tension spring or a torsion spring, etc. The storage plate 31 can be guided and slid by a guide rod and a guide block, or it can be guided and slid by a guide hole and a guide rod.

[0033] The frame 1 is equipped with a lifting platform 81 and a lifting drive 82 (preferably driven by an electric cylinder, but can also be driven by a motor or pneumatic cylinder) at the stacking station 3. The frame 1 is also equipped with a counting sensor 9 for detecting the number of packaging bags falling (preferably a photoelectric sensor, but can also be other sensors with counting functions, which can be purchased directly from the market). When the counting sensor 9 detects the corresponding number passing by, the lifting drive 82 drives the lifting platform 81 to rise, thereby raising the packaging bags at the corresponding position. At this time, the employee can take out the corresponding packaging bag according to the raised position and tie it up. With intelligent counting, the employee does not need to keep watching the number of packaging bags falling, making it more convenient to use. One employee can be responsible for multiple machines.

[0034] A baffle plate 10 is rotatably mounted on the frame 1 at the position corresponding to the side abutment 321, and a sensor 20 is mounted on the frame 1 at the position corresponding to the baffle plate 10. The baffle plate 10 can prevent employees from putting their hands into the bag pushing station 4 during operation. When the baffle plate 10 is rotated down, it can trigger the sensor 20 (the sensor 20 is preferably an infrared sensor, which can be purchased directly from the market and will not be described in detail in this article), thereby stopping the machine from working, which not only improves safety performance, but also makes it easier for employees to handle faults.
