It is a multi-purpose packaging machine integrating electronic weighing, automatic feeding, automatic bag removal, dust removal, and vibration. It boasts a high degree of automation, high packaging accuracy, and adjustable packaging speed. Its unique structure makes handling ton bag packaging particularly easy and facilitates subsequent processing. The simple ton bag packaging machine is suitable for ton bag packaging of materials in the mining, chemical, building materials, grain, and feed industries. Its simple structure ensures stable operation during packaging, guaranteeing long-term stable working conditions. Its simple operation greatly reduces manufacturing and maintenance costs.

[0003] A search revealed that CN211108116U discloses a ton bag packaging machine, including a support frame and a lifting cylinder located at the center of the upper part of the support frame. The lifting cylinder drives a lifting guide column to move. The lifting guide column is connected to a bag hanging bracket via upper and lower connecting accessories. A bag hanging assembly is located below the bag hanging bracket. The bag hanging assembly includes a bag clamp driven by a bag unloading cylinder for hooking the ton bag packaging bag. A lifting bellows tube surrounds the outer side of the upper and lower connecting accessories. The lower part of the lifting bellows tube is connected to a feeding nozzle. The feeding nozzle is fixedly connected to the upper and lower connecting accessories and moves up and down synchronously with the lifting cylinder. This ton bag packaging machine uses a vibration motor to compact the packaging bags, making it particularly suitable for packaging bags containing gaseous dust. The entire packaging machine integrates high and low speed feeding functions, effectively addressing the speed and accuracy requirements during the packaging process.

[0004] Existing ton bag packaging machine technology has the following problems: 1. The existing ton bag packaging machine has a weighing platform fixed to the equipment bracket and uses a weighing sensor connected by a bag clamp. The weighing process is easily affected by equipment vibration and lifting movements, and there is no special balance buffer design, which may affect the weighing accuracy. 2. The existing bag hanging device of the ton bag packaging machine relies on "the bag unloading cylinder to drive the bag hanging clamp to directly clamp the bag mouth". The structure is relatively simple, but the clamping stability depends on the clamping force, which may cause problems such as the lifting lug falling off or the bag unloading not being smooth. Utility Model Content

[0005] The purpose of this utility model is to provide a simple ton bag packaging machine to solve the problems mentioned in the background art, such as the impact of interference on weighing accuracy, the detachment of lifting lugs, or the unloading of bags.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a simple ton bag packaging machine, including a frame and ton bags. A feeding pipe is provided at the center of the top of the frame. A dust removal fan for sucking up dust generated during the packaging process is fixed on one side of the top of the frame. Four weighing sensors are rectangularly distributed on the top of the frame, and the four weighing sensors together suspend a weighing frame. Four balance rods are hinged to the outside of the weighing frame, and the bottoms of the four balance rods are connected to a pallet platform for supporting the ton bags through a balance buffer assembly. Vibrators are fixedly installed on both sides of the pallet platform. Bag hanging devices for hooking the ton bags are provided on both sides of the weighing frame. A feeding bag clamping device for clamping the ton bag opening to the feeding pipe is provided in the middle of the weighing frame.

[0007] Preferably, the top corner of the ton bag is provided with lifting lugs, and a flexible hose is connected to the center of the top of the ton bag, with an elastic band embedded at the top of the flexible hose.

[0008] Preferably, the bag hanging device includes a first cylinder and a hook rod. The piston rod of the first cylinder is hinged to a crank arm fixed to the hook rod, and the other end of the first cylinder is hinged to a weighing frame. Both ends of the hook rod are rotatably connected to bearing seats fixed to the weighing frame, and a fixed hook for hooking the lifting lug is fixed on the hook rod.

[0009] Preferably, the bottom of the weighing frame is fixed with a baffle for stopping the fixed hook in the closed state.

[0010] Preferably, the feeding bag clamping device includes two symmetrically arranged semi-clamping rings, and two bent clamps are fixed at both ends of the semi-clamping rings. The two bent clamps are fixedly connected to each other by a first crossbar and a second crossbar distributed vertically.

[0011] Preferably, the feeding bag clamping device further includes a second cylinder, the two ends of which are respectively hinged to two symmetrically arranged curved clamps.

[0012] Preferably, the balance buffer assembly includes a U-shaped support and a fixed seat. The U-shaped support is hinged to the lower end of the balance rod by a pin, and the fixed seat is fixed to the tray platform. A rubber pad that abuts against the fixed seat is fixed to the inner bottom of the U-shaped support.

[0013] Preferably, the feeding pipe has a dust suction port on its side, and the dust suction port is connected to the dust removal fan through a bellows pipe.

[0014] Compared with the prior art, this utility model provides a simple ton bag packaging machine, which has the following beneficial effects: 1. This utility model weighing frame connects the pallet platform with a balance buffer assembly via four balance rods. The rubber pads abut against the fixed base to absorb vibration impact, reducing interference with the weighing sensor when the pallet platform vibrator is working, ensuring weighing accuracy. The suspended design allows the weight to be fully borne by the weighing sensor. The balance rods and the buffer assembly form a "flexible connection," which not only ensures stable support for the ton bag but also filters vibration energy through the elastic buffer of the rubber pads, solving the problem of "conflict between vibration compaction and weighing accuracy." 2. The bag hanging device of this utility model consists of a first cylinder, a hook rod, a curved arm, a bearing seat, and a fixed hook: the first cylinder drives the hook rod to rotate around the bearing seat through the curved arm, and the fixed hook rotates with the hook rod to realize the "hooking-releasing" action of the bag lifting lug. It is more suitable for the force characteristics of the bag lifting lug than the "clamping type" in the prior art (the lifting lug is ring-shaped, and the hook hook is more stable).

[0016] 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.

[0017] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a simple ton bag packaging machine, including a frame 1 and ton bags 13. A feeding pipe 12 is provided at the center of the top of the frame 1. A dust removal fan 2 is fixed on one side of the top of the frame 1 to suck up the dust generated during the packaging process. Four weighing sensors 3 are rectangularly distributed on the top of the frame 1, and the four weighing sensors 3 are suspended together by a weighing frame 4. Four balance rods 8 are hinged to the outside of the weighing frame 4, and the bottom of the four balance rods 8 are connected to a pallet platform 10 for supporting the ton bags 13 through a balance buffer assembly 9. Vibrators 11 are fixedly installed on both sides of the pallet platform 10. Bag hanging devices 6 for hooking the ton bags 13 are provided on both sides of the weighing frame 4. A feeding bag clamping device 5 for clamping the bag opening of the ton bag 13 to the feeding pipe 12 is provided in the middle of the weighing frame 4.

[0018] Please see Figure 8 The top corner of the ton bag 13 is connected with lifting lugs 133. The top center of the ton bag 13 is connected to a flexible hose 131. The top of the flexible hose 131 is fitted with an elastic band 132. The ton bag 13 itself is designed with a flexible hose 131 with an elastic band 132. The elastic band 131 can be pre-shrinked and fitted to the outside of the feeding pipe 12. With the mechanical clamping of the feeding bag clamping device 5, a double seal is formed to prevent material leakage during feeding.

[0019] Please see Figure 4 , Figure 5 and Figure 6The bag-hanging device 6 includes a first cylinder 61 and a hook rod 62. The piston rod of the first cylinder 61 is hinged to a crank arm 65 fixed on the hook rod 62. The other end of the first cylinder 61 is hinged to the weighing frame 4. The two ends of the hook rod 62 are rotatably connected to bearing seats 63 fixed on the weighing frame 4. A fixed hook 64 for hooking the lifting lug 133 is fixed on the hook rod 62. The bag-hanging device 6 consists of a first cylinder 61, a hook rod 62, a crank arm 65, a bearing seat 63, and a fixed hook 64. The first cylinder 61 drives the hook rod 62 to rotate around the bearing seat 63 through the crank arm 65. The fixed hook 64 rotates with the hook rod 62 to realize the "hooking-releasing" action of the lifting lug 133 on the ton bag 13.

[0020] The bottom of the weighing frame 4 is fixed with a baffle 7 for stopping the fixed hook 64 in the closed state. The baffle 7 at the bottom of the weighing frame 4 can limit the closing angle of the fixed hook 64, prevent excessive rotation that would cause the ton bag 13 to be pulled up and detached from the pallet, and improve the safety of the hanging bag.

[0021] Please see Figure 4 , Figure 5 and Figure 7 The feeding bag clamping device 5 includes two symmetrically arranged semi-clamping rings 51, and two bent clamps 52 are fixed at both ends of the semi-clamping rings 51. The two bent clamps 52 are fixedly connected to each other by a first crossbar 53 and a second crossbar 54 distributed vertically. The semi-clamping rings 51 can fit against the outer wall of the feeding pipe 12, and the bent clamps 52 cooperate with the crossbars to form a stable frame.

[0022] Furthermore, the feeding bag clamping device 5 also includes a second cylinder 55, with its two ends hinged to two symmetrically arranged curved clamps 52. The second cylinder 55 drives the half clamping ring 51 to close, which can tightly clamp the hose 131 of the ton bag 13 onto the feeding pipe 12.

[0023] Please see Figure 1 and Figure 2 The balance buffer assembly 9 includes a U-shaped support 91 and a fixed seat 92. The U-shaped support 91 is hinged to the lower end of the balance rod 8 by a pin 94. The fixed seat 92 is fixed on the pallet platform 10. A rubber pad 93 is fixed on the inner bottom of the U-shaped support 91, which abuts against the fixed seat 92. The rubber pad 93 abuts against the fixed seat 92 to absorb vibration impact, reduce interference of the vibrator 11 on the pallet platform 10 with the weighing sensor 3 when it is working, and ensure weighing accuracy.

[0024] In a preferred embodiment, the feeding pipe 12 is provided with a dust suction port 121 on the side. The dust suction port 121 is connected to the dust removal fan 2 through a bellows tube. The dust suction port 121 and the feeding pipe 12 are integrated into one design, which shortens the dust diffusion path. The flexible connection of the bellows tube can adapt to the slight shaking of the weighing frame 4, ensuring that the dust suction is continuous and effective and improving the cleanliness of the working environment.

[0025] The working principle and usage process of this utility model are as follows: A pallet is manually placed on the pallet platform 10, and the ton bag 13 is placed on the pallet. The first cylinders 61 on both sides drive the hook rod 62 to rotate via the crank arm 65, causing the fixed hooks 64 on the hook rod 62 to rotate and open. The four lifting lugs 133 of the ton bag 13 are then hooked onto the fixed hooks 64 on the hook rods 62 on both sides. The hook rod 62 continues to rotate until the fixed hooks 64 contact the baffle plate 7. The second cylinder 55 then operates, pushing the two semi-clamping rings 51 open via the bending clamp 52. The elastic band 132 at the top of the hose 131 is then stretched open and placed over the lower opening of the feeding pipe 12. The elastic band 132 is then loosened. The bag is closed and then clamped by two half-clamping rings 51 to prevent the hose 131 from slipping down. After the bag opening of the ton bag 13 is sealed, the bag can be filled. At the same time as the filling, the dust removal fan 2 and the vibrator 11 work. The vibrator 11 vibrates and compacts the material, and the dust removal fan 2 sucks up the dust generated during the filling process to prevent dust from being raised. The weighing sensor 3 weighs and controls the filling amount. The filling stops when the required amount is reached. After the filling is completed, the first cylinder 61 pushes the hook rod 62 to rotate through the crank arm 65, so that the fixed hook 64 on the hook rod 62 rotates and opens, automatically removing the lifting lug 133. Then, the forklift equipment carries away the pallet and the ton bag 13 together, thus completing one packaging cycle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
