Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to an automatic assembly machine for ton bags that is easy to bag. Background Technology

[0002] A ton bag assembly machine, also known as a ton bag packaging machine or ton bag machine, is an automated piece of equipment used for large-scale material packaging. It is widely used in many industries such as chemical, building materials, food, and mining to automatically complete the ton bag packaging process, enabling the packaging of powdery, granular, and lumpy materials. The packaging capacity is generally between 500 and 2000 kg.

[0003] Traditional ton bag machines require manual binding of the bag opening with rope to prevent material from falling off during loading. This method has several drawbacks in practice. For example, it is inefficient. Manual binding involves multiple steps, including taking the rope, wrapping it around the bag opening, tying a knot, and untying after loading, which is time-consuming and labor-intensive. For larger diameter discharge openings, one person often cannot complete the binding work, requiring multiple workers to work together to keep up with the machine's pace. Furthermore, manual binding cannot completely seal the bag opening and discharge opening, leaving gaps. During loading, especially when powdered fertilizer falls at high speed from the discharge opening, the air inside the bag is impacted, creating airflow. Some fine particles escape from these gaps, causing dust to adhere to the equipment surface and floor, increasing cleaning burden. This dust can also be inhaled by workers operating nearby, potentially leading to respiratory illnesses over time, thus limiting the machine's effectiveness. Utility Model Content

[0004] One of the technical problems this application aims to solve is that, in the use of traditional ton bag machines, the bag opening needs to be manually tied with ropes to the outside of the material opening to prevent the material from falling off during loading, which has many shortcomings in actual use.

[0005] To solve the above-mentioned technical problems, this application provides an automatic ton bag assembly machine that facilitates bagging, including a frame. A binding mechanism is fixedly installed in the middle of the frame. The binding mechanism includes two horizontal plates, and a fixing plate is fixedly installed in the middle of the two horizontal plates. A cylinder 1 and a cylinder 2 are fixedly installed in the middle of the upper end of the fixing plate, respectively. The cylinder 1 and cylinder 2 face opposite directions. Guide rods are fixedly installed on both sides of the middle of the upper end of the fixing plate. A push plate is fixedly installed at the output end of cylinder 2. Push rods are fixedly installed at both ends of the push plate. U-shaped plates are fixedly installed at one end of the two push rods and the output end of cylinder 1, respectively. Columns are fixedly installed on both sides of the upper end of the two U-shaped plates. Arc-shaped clamps are rotatably engaged at the upper ends of the two sets of columns. A spring is fixedly installed between every two arc-shaped clamps located on one side. Brackets are fixedly installed on both sides of the upper end of the fixing plate. A collar is fixedly installed at one end of the two brackets. An air bladder is fixedly installed on the inner wall of the collar.

[0006] In some embodiments, a base plate is fixedly installed at the lower end of the frame, a pallet is placed at the upper end of the base plate, and a square ton bag is provided at the upper end of the pallet.

[0007] In some embodiments, pull strips are fixedly connected to the four corners of the square ton bag, and an extendable bag opening is fixedly connected to the middle of the upper end of the square ton bag.

[0008] In some embodiments, a hopper is fixedly installed in the middle of the upper end of the frame, a feeding pipe is fixedly connected to the lower end of the hopper, a feeding pipe is fixedly connected to one side of the upper end of the hopper, and the extendable bag opening is sleeved on the outside of the feeding pipe.

[0009] In some embodiments, telescopic rods are fixedly installed at the four corners of the upper end of the frame, and hooks are fixedly installed at the output ends of the four telescopic rods. The four hooks are respectively hooked to the pull strips at the four corners of the square ton bag.

[0010] In some embodiments, one end of the airbag is connected to a connecting air tube through a collar, the collar and a plurality of arc-shaped clamps are respectively located above and below the middle of the feed tube, the airbag on the inner wall of the collar abuts against the outer wall of the feed tube when inflated, and the collar is located above the plurality of arc-shaped clamps.

[0011] In some embodiments, the two cylinders are respectively slidably engaged below the middle of both sides of the U-shaped plate connected to the cylinders, and the two push rods respectively pass through the upper part of the middle of both sides of the U-shaped plate connected to the cylinders, with one end of each cylinder passing through the upper part of the middle of both sides of the U-shaped plate connected to the two push rods.

[0012] In some embodiments, a locking groove is provided above one end and below the other end of the plurality of arc-shaped clamps, and the ends of the plurality of arc-shaped clamps can be spliced ​​together through the corresponding locking grooves.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. This utility model enables rapid binding and effective sealing of the bag opening of a ton bag. Through the coordinated action of the arc-shaped clamping plate and the airbag driven by a cylinder, the bag opening can be quickly fixed without manual rope binding, significantly improving binding efficiency. Simultaneously, the arc-shaped clamping plate clamps tightly from below, while the airbag inflates and seals from above, forming a double-sealed structure that greatly reduces dust leakage. This avoids the uneven tightness problem of traditional manual binding and effectively prevents dust diffusion during material filling, while also ensuring ease of operation and environmental friendliness in production.

[0015] 2. This utility model is highly adaptable and environmentally friendly in use. By adjusting the elasticity of the arc-shaped clamp and the inflation volume of the airbag, it can be adapted to different diameter bag openings and feed tube sizes, making the device more practical.

[0022] 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.

[0023] Reference Figures 1 to 5As shown, one embodiment of this utility model includes a frame 1. A binding mechanism 2 is fixedly installed in the middle of the frame 1. The binding mechanism 2 includes two horizontal plates 21. A fixing plate 22 is fixedly installed in the middle of the two horizontal plates 21. A cylinder 1 23 and a cylinder 24 are fixedly installed in the middle of the upper end of the fixing plate 22, respectively. The cylinder 1 23 and the cylinder 24 face opposite directions. Guide rods 25 are fixedly installed on both sides of the middle of the upper end of the fixing plate 22. A push plate 26 is fixedly installed at the output end of the cylinder 24. Push rods 27 are fixedly installed at both ends of the push plate 26. U-shaped plates 28 are fixedly installed at one end of the two push rods 27 and the output end of the cylinder 1 23, respectively. Columns 29 are fixedly installed on both sides of the upper end of the two U-shaped plates 28. Arc-shaped clamps 30 are rotatably engaged at the upper ends of the two sets of columns 29. A spring 31 is fixedly installed between every two arc-shaped clamps 30 located on one side. Supports are fixedly installed on both sides of the upper end of the fixing plate 22. The frame 33 has a collar 34 fixedly installed at one end of each of the two supports 33. An air bladder 35 is fixedly installed on the inner wall of the collar 34. One end of the air bladder 35 passes through the collar 34 and is connected to a connecting air pipe 36. The collar 34 and multiple arc-shaped clamps 30 are located above and below the middle of the feed pipe 20, respectively. When the air bladder 35 on the inner wall of the collar 34 is inflated, it abuts against the outer wall of the feed pipe 20. The collar 34 is located above the multiple arc-shaped clamps 30. Two cylinders 23 are slidably engaged. Below the middle of both sides of the U-shaped plate 28 connected to cylinder 23, two push rods 27 pass through the upper part of the middle of both sides of the U-shaped plate 28 connected to cylinder 23. One end of each of the two cylinders 23 passes through the upper part of the middle of both sides of the U-shaped plate 28 connected to the two push rods 27. The upper part of one end of the multiple arc-shaped clamping plates 30 and the lower part of the other end are respectively provided with locking grooves 32. The ends of the multiple arc-shaped clamping plates 30 can be spliced ​​through the corresponding locking grooves 32.

[0024] In this embodiment, the extendable bag opening 14 on the top of the square ton bag 13 can be quickly tied. During use, simply pull the extendable bag opening 14 on the top of the unfilled square ton bag 13 upwards, raising it above the height of the collar 34. Then, driven by cylinders 23 and 24, the two sets of arc-shaped clamping plates 30 automatically engage. The reverse movement of the output ends of cylinders 23 and 24 is transmitted to the column 29 via push rod 27 and U-shaped plate 28, causing the arc-shaped clamping plates 30 to close around the rotation point. Combined with the splicing and positioning of the locking groove 32, this quickly completes the initial fixation with the feeding pipe 20. After the arc-shaped clamping plates 30 close, they can encircle the bag opening from below, using the elastic potential energy of the spring 31 to maintain a stable clamping force, preventing the bag opening from loosening due to material impact during filling. Simultaneously, the air bladder on the inner wall of the collar 34... After being inflated through the connecting air pipe 36, the air bladder 35 fits tightly against the outer wall of the discharge pipe 20, further sealing and fixing the bag opening from above, forming a coordinated fixing effect from top to bottom. The arc-shaped clamping plate 30 is connected by a spring 31, providing a certain amount of elastic adjustment space. Combined with the flexible splicing of the locking groove 32, it can adapt to the opening of ton bags of different diameters. The air bladder 35 adjusts the inflation volume through the connecting air pipe 36, and can adjust the clamping force according to the change of the outer wall size of the discharge pipe 20. After the arc-shaped clamping plate 30 is closed, it fits tightly against the bag opening. After the air bladder 35 is inflated, it can fill the gap between the collar 34 and the discharge pipe 20, and the two together form a nearly sealed space. This can effectively limit the airflow generated by the falling material during loading to inside the bag, thereby effectively reducing the amount of dust overflowing from the gap between the bag opening and the material outlet, improving the working environment and protecting the health of operators.

[0025] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, a base plate 11 is fixedly installed at the lower end of the frame 1, a tray 12 is placed at the upper end of the base plate 11, a square ton bag 13 is provided at the upper end of the tray 12, and a pull strip 15 is fixedly connected to each of the four corners of the square ton bag 13. An extendable bag opening 14 is fixedly connected to the middle of the upper end of the square ton bag 13. A hopper 18 is fixedly installed at the middle of the upper end of the frame 1, a discharge pipe 20 is fixedly connected to the lower end of the hopper 18, and an inlet pipe 19 is fixedly connected to one side of the upper end of the hopper 18. The extendable bag opening 14 is fitted onto the outside of the discharge pipe 20. Telescopic rods 16 are fixedly installed at each of the four corners of the upper end of the frame 1, and hooks 17 are fixedly installed at the output ends of the four telescopic rods 16. The four hooks 17 are respectively hooked to the pull strips 15 at the four corners of the square ton bag 13.

[0026] In this embodiment, the base plate 11 at the lower end of the frame 1 provides a stable placement platform for the pallet 12, which can evenly transfer the weight of the pallet 12, the square ton bag 13 and the internal materials to the ground, avoiding damage to the workshop floor due to excessive local pressure, and ensuring that the pallet 12 carrying the square ton bag 13 will not shift or shake during the loading process. At the same time, the telescopic rods 16 at the four corners of the upper end of the frame 1 are hooked to the pull strips 15 at the four corners of the square ton bag 13 through hooks 17, which can pull and position the ton bag from four directions. This positioning method can accurately guide the extendable bag opening 14 to the outside of the discharge pipe 20, ensuring the coaxiality of the bag opening and the discharge pipe 20, avoiding loading misalignment caused by ton bag offset, reducing the situation of material spilling outside the bag, and improving the accuracy of loading. As materials are continuously loaded into the square ton bag 13, its weight gradually increases, and the four telescopic rods 16 can adjust the extension length according to the load-bearing capacity of the ton bag, and provide continuous and balanced tension to the four corners of the ton bag through the pull strips 15. This not only prevents the ton bags from tipping over due to a shift in the center of gravity during the filling process, but also keeps the ton bags in a stable square shape, ensuring that the material is filled evenly and avoiding damage to the bag caused by local over-expansion. After the filling is completed, the pallet 12 carries the full square ton bags 13, which can be directly removed from the base plate 11 by forklifts or other handling equipment and put into storage or transportation.

[0027] Working principle: In use, first place the empty square ton bag 13 on the tray 12 on the base plate 11, ensuring the ton bag is placed stably. Then, activate the telescopic rods 16 at the four corners of the upper part of the frame 1, so that the hooks 17 at their output ends hook onto the ends of the pull strips 15 at the four corners of the square ton bag 13. By adjusting the extension length of the telescopic rods 16, apply a balanced pulling force to the ton bag from four directions, positioning the ton bag in the middle of the frame 1. Then, manually pull the extendable bag opening 14 upwards, raising it above the height of the collar 34, and place it on the outside of the feed tube 20. At this time, the bag opening is in a waiting-to-be-fixed state, waiting for the binding mechanism 2 to act.

[0028] During binding, cylinders 23 and 24 are activated, with their output ends moving in opposite directions. This pushes the U-shaped plates 28 on both sides to move towards each other via push rod 27, causing the column 29 and the arc-shaped clamping plate 30 to close around the rotation point. The arc-shaped clamping plates 30 on both sides are precisely spliced ​​through the locking grooves 32 at the ends, encircling the extendable bag opening 14 from below. At the same time, the spring 31 between the clamping plates is compressed, using elastic potential energy to provide a stable clamping force, preventing the bag opening from loosening due to material impact during loading. Subsequently, air is inflated into the air bladder 35 on the inner wall of the collar 34 through the connecting air pipe 36. After the air bladder 35 expands, it can fit tightly against the outer wall of the feeding pipe 20, further sealing the gap between the bag opening and the feeding pipe 20 from above, forming a double fixing effect of clamping from below and sealing from above, ensuring that the bag opening is completely fixed and sealed. Material enters the hopper 18 through the feed pipe 19 and is continuously injected into the square ton bag 13 through the discharge pipe 20. As the amount of material increases, the weight of the ton bag gradually increases. The four telescopic rods 16 automatically adjust their telescopic length according to the load. The pull strips 15 continuously pull the four corners of the ton bag to prevent the center of gravity of the ton bag from shifting and tipping over, while maintaining its square shape to ensure that the material is filled evenly and to prevent local over-expansion that could cause the bag to break. During the filling process, the sealed space formed by the arc-shaped clamp 30 and the airbag 35 restricts the airflow generated by the falling material inside the bag, greatly reducing dust spillage and protecting the working environment.

[0029] Once the ton bag is filled to the preset weight, the feeding pipe 19 stops feeding, completing the filling process. The air bladder 35 releases air through the connecting air pipe 36, and the cylinders 23 and 24 move in opposite directions, causing the arc-shaped clamp 30 to loosen and release the fixation on the extendable bag opening 14. After the hook 17 is separated from the pull strip 15, the telescopic rod 16 retracts, and the bag opening can be closed manually or mechanically. Finally, the pallet 12 carrying the full ton bag is removed from the base plate 11 by a forklift or other equipment and enters the warehousing or transportation stage, completing the entire packaging process.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
