Description

Technical Field

[0001] This utility model belongs to the field of plastic container bag processing, and specifically relates to a flattening device for processing plastic container bags. Background Technology

[0002] FIBCs, also known as flexible container bags, ton bags, or space bags, are a type of unitized transport equipment. When used with cranes or forklifts, they enable unitized transport of bulk, granular, or powdery materials. FIBCs are flexible transport packaging containers widely used for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. Developed countries commonly use FIBCs as packaging for transportation and warehousing.

[0003] Chinese Patent No. CN216782855U discloses a plastic FIBC (Flexible Intermediate Bulk Container) processing and flattening device, belonging to the field of plastic FIBC processing technology. It solves the problems of current flattening devices being unable to limit the position of the FIBC and being inconvenient for collection. This plastic FIBC processing and flattening device includes a first body and a second body, with a conveyor belt between them. A fixed block is located on the left side of the top of both the first and second bodies, and a movable rod is movably connected inside the fixed block. The movable rod has several limiting holes on its surface. A limiting pin is located on the top of the fixed block, and the other end of the limiting pin passes through the fixed block and engages with the limiting hole. A pull plate is fixedly connected to one end of the movable rod, and a limiting plate is fixedly connected to the other end. This invention can limit the position of the FIBC during the conveying process and also facilitates the collection of the flattened FIBC.

[0004] As can be seen from the above structure, by moving the movable rod back and forth with the pull plate, the distance of the limiting plate on the conveyor belt can be adjusted, which is convenient for limiting the position of FIBCs of different sizes and preventing the position of the FIBCs from shifting during transportation, which would cause deviation in flattening and affect the flattening effect. However, as can be seen from the above figure and text, the two limiting plates need to be adjusted separately during use, which leads to waste and reduces the flattening efficiency of the equipment. In addition, the bottom of the limiting plate is in contact with the surface of the conveyor belt for a long time, which may cause wear on the conveyor belt or the limiting plate, resulting in the inability to effectively limit the position. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a flattening device for processing plastic bulk bags, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A flattening device for processing plastic container bags includes a conveyor belt body. A flattening structure is fixedly connected to one side of the upper end of the conveyor belt body, and an installation assembly is fixedly connected to the other side of the upper end of the conveyor belt body. A pressure application assembly is fixedly connected to the other end of each installation assembly. A limit assembly is fixedly connected to the opposite side of each pressure application assembly. The limit assembly includes an adjusting rod disposed on the opposite side of the pressure application assembly. An adjusting groove is formed at the lower end of the adjusting rod. Adjusting screws are rotatably connected to both sides of the inner side of the adjusting groove. Threaded parts are threaded onto the outer surface of each adjusting screw. A limit plate is fixedly connected to the other end of each threaded part. The limit plate is slidably connected to the conveyor belt body. A driven bevel gear is fixedly connected to the other end of each adjusting screw. A driving bevel gear is rotatably connected to the inner side of the adjusting groove. The driving bevel gear and the driven bevel gear are meshed with each other.

[0008] As a preferred technical solution, the installation component includes installation plates disposed on both sides of the conveyor belt body, with a snap-fit ​​block fixedly connected to the upper end of the installation plate, and a snap-fit ​​frame fixedly connected to the outer side of the pressure application component, the snap-fit ​​frame and the snap-fit ​​block being interlocked.

[0009] As a preferred technical solution, the outer side of the snap-fit ​​frame is provided with snap-fit ​​holes, the outer side of the snap-fit ​​block is provided with a circular groove, a snap-fit ​​spring is fixedly connected inside the circular groove, and the other end of the snap-fit ​​spring is fixedly connected with a snap-fit ​​connector, which snaps into the snap-fit ​​holes.

[0010] As a preferred technical solution, the pressure application component includes a movable frame disposed at the other end of the mounting component. The movable frame is slidably connected to a movable slider. The opposite sides of the movable slider are fixedly connected to a limiting component. A pressure spring is fixedly connected to the lower end of the movable frame. The other end of the pressure spring is fixedly connected to the movable slider.

[0011] As a preferred technical solution, the movable slider and the interior of the movable frame are slidably inserted into each other, the outer surface of the movable slider is provided with a guide hole, and the interior of the movable frame is fixedly connected with a guide rod, which is slidably inserted into the guide hole.

[0012] As a preferred technical solution, the other end of the active bevel gear is fixedly connected to a turntable through the adjustment frame, the other end of the turntable is fixedly connected to the outer ring of a bearing, and the inner ring of the bearing is fixedly connected to a handle.

[0013] As a preferred technical solution, the lower end of the limiting plate is evenly provided with multiple rolling grooves, and rolling balls are rotatably connected inside the rolling grooves. The limiting plate is slidably connected to the conveyor belt body through the rolling balls.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, through the setting of the limiting component, can limit the plastic container bag through the two limiting plates of the limiting component during use, thereby preventing the plastic container bag from shifting position when moving. When it is necessary to adjust the distance between the two limiting plates, the driving bevel gear is rotated to drive the driven bevel gear to rotate. The rotation of the driven bevel gear drives the adjusting screw to rotate. The rotation of the adjusting screw causes the threaded part connected to it to move. The limiting plates are all fixedly connected to the threaded part, so the movement of the threaded part drives the movement of the limiting plates. This allows for flexible adjustment of the limiting plates during use, making it more convenient to limit different plastic container bags.

[0016] Secondly, the installation components of this utility model, when used, involve installing the limiting component to the conveyor belt body. First, the snap-fit ​​block is inserted into the snap-fit ​​frame. During insertion, the snap-fit ​​connector is squeezed into the circular groove. Then, after the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the snap-fit ​​hole aligns with the circular groove. At this point, the snap-fit ​​connector pops out of the circular groove under the action of the snap-fit ​​spring, allowing it to snap into the snap-fit ​​hole, thus achieving a snap-fit ​​effect. This facilitates the installation of the limiting component, and the snap-fit ​​method makes installation and disassembly of the limiting component more convenient. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a flattening device for processing plastic container bags includes a conveyor belt body 1. A flattening structure 2 is fixedly connected to one side of the upper end of the conveyor belt body 1. An installation component 3 is fixedly connected to the other side of the upper end of the conveyor belt body 1. A pressure application component 4 is fixedly connected to the other end of the installation component 3. A limit component 5 is fixedly connected to the opposite side of the pressure application component 4. The limit component 5 includes an adjusting rod 51 disposed on the opposite side of the pressure application component 4. An adjusting groove 52 is opened at the lower end of the adjusting rod 51. An adjusting screw 53 is rotatably connected to both sides of the inner side of the adjusting groove 52. A threaded part 54 is threadedly connected to the outer surface of the adjusting screw 53. A limit plate 55 is fixedly connected to the other end of the threaded part 54. The limit plate 55 is slidably connected to the conveyor belt body 1. A driven bevel gear 56 is fixedly connected to the other end of the adjusting screw 53. A driving bevel gear 57 is rotatably connected to the inner side of the adjusting groove 52. The driving bevel gear 57 and the driven bevel gear 56 are meshed with each other.

[0024] refer to Figures 1-4 The mounting assembly 3 includes mounting plates 33 disposed on both sides of the conveyor belt body 1. A snap-fit ​​block 34 is fixedly connected to the upper end of the mounting plate 33. A snap-fit ​​frame 31 is fixedly connected to the outer side of the pressure application assembly 4. The snap-fit ​​frame 31 and the snap-fit ​​block 34 are interlocked. Snap-fit ​​holes 32 are provided on the outer side of each snap-fit ​​frame 31. A circular groove 35 is provided on the outer side of each snap-fit ​​block 34. A snap-fit ​​spring 36 is fixedly connected inside the circular groove 35. A snap-fit ​​connector 37 is fixedly connected to the other end of the snap-fit ​​spring 36. The snap-fit ​​connector 37 is engaged with the snap-fit ​​hole 32. Interlocking; by inserting the snap-fit ​​block 34 into the snap-fit ​​frame 31, the snap-fit ​​connector 37 is squeezed into the circular groove 35 during insertion. After the snap-fit ​​block 34 is fully inserted into the snap-fit ​​frame 31, the position of the snap-fit ​​hole 32 is consistent with the position of the circular groove 35. At this time, the snap-fit ​​connector 37 will pop out of the circular groove 35 under the action of the snap-fit ​​spring 36, so that the snap-fit ​​connector 37 and the snap-fit ​​hole 32 can be snapped together, thereby achieving the snap-fit ​​effect and making it convenient to install the limiting component 5.

[0025] refer to Figures 1-3The pressure-applying component 4 includes a movable frame 41 disposed at the other end of the mounting component 3. Movable sliders 42 are slidably connected inside the movable frame 41. The opposite sides of the movable sliders 42 are fixedly connected to the limiting component 5. A pressure-applying tension spring 43 is fixedly connected to the lower end of the movable frame 41. The other end of the pressure-applying tension spring 43 is fixedly connected to the movable sliders 42. In use, the pressure-applying tension spring 43 can pull the movable sliders 42. Since the limiting component 5 is fixedly connected to the movable sliders 42, the pressure-applying tension spring 43 can pull the limiting component 5, thereby allowing the limiting component 5 to fit tightly against the conveyor belt body 1. This prevents gaps from appearing at the bottom of the limiting component 5, which could cause the plastic container bag to get stuck in the gaps.

[0026] refer to Figure 3 The movable slider 42 and the movable frame 41 are slidably inserted into each other. A guide hole 44 is provided on the outer surface of the movable slider 42. A guide rod 45 is fixedly connected inside the movable frame 41. The guide rod 45 and the guide hole 44 are slidably inserted into each other. The guide rod 45 and the guide hole 44 provide a limiting and guiding effect for the movable slider 42 during use, thereby making the movable slider 42 move more stably during use.

[0027] refer to Figure 3 The other end of the drive bevel gear 57 is fixedly connected to the turntable 6 through the adjustment frame. The other end of the turntable 6 is fixedly connected to the outer ring of the bearing 7, and the inner ring of the bearing 7 is fixedly connected to the handle 8. First, hold the handle 8 and then rotate the turntable 6. The rotation of the turntable 6 can rotate the drive bevel gear 57 fixedly connected to it, so that the drive bevel gear 57 can be rotated under the action of the turntable 6 and the handle 8.

[0028] refer to Figure 2 The lower end of the limiting plate 55 is evenly provided with multiple rolling grooves 58, and rolling balls 59 are rotatably connected inside the rolling grooves 58. The limiting plate 55 is slidably connected to the conveyor belt body 1 through the rolling balls 59. The rolling balls 59 can reduce the friction between the limiting plate 55 and the conveyor belt body 1, thereby increasing the service life of the conveyor belt body 1 and the limiting plate 55 during use.

[0029] Operating principle and advantages: First, by moving the device to a suitable position, installing the limiting component 5, and inserting the snap-fit ​​block 34 into the snap-fit ​​frame 31, the snap-fit ​​connector 37 is squeezed into the circular groove 35 during insertion. Then, after the snap-fit ​​block 34 is fully inserted into the snap-fit ​​frame 31, the position of the snap-fit ​​hole 32 aligns with the position of the circular groove 35. At this point, the snap-fit ​​connector 37 will pop out of the circular groove 35 under the action of the snap-fit ​​spring 36, allowing the snap-fit ​​connector 37 to snap into the snap-fit ​​hole 32, thus achieving the snap-fit ​​effect. This facilitates the installation of the limiting component 5. Then, by placing the plastic container bag on the upper end of the conveyor belt body 1 for conveying, the two limiting plates 55 of the limiting component 5 limit the plastic container bag during conveying, preventing positional deviation during movement. Simultaneously, under the action of the pressure spring 43, the moving slider 42 can be pulled. Since the limiting component 5 and the moving slider 42 are fixedly connected, this ensures that under pressure... The tension spring 43 can pull the limiting component 5, allowing it to fit tightly against the conveyor belt body 1. This prevents gaps at the bottom of the limiting component 5 from causing the plastic container bag to get stuck. The plastic container bag can then accurately enter the flattening structure 2 for flattening. When adjusting the distance of the limiting plate 55, the driving bevel gear 57 is rotated to drive the driven bevel gear 56. The driven bevel gear 56 rotates, which in turn drives the adjusting screw 53. The adjusting screw 53 moves the threaded part 54, which is fixedly connected to the limiting plate 55. The movement of the threaded part 54 moves the limiting plate 55, allowing for flexible adjustment of the limiting plate 55. This makes it easier to limit different plastic containers. The rolling ball 59 reduces the friction between the limiting plate 55 and the conveyor belt body 1, increasing the service life of both.
