Description

Technical Field

[0001] This utility model belongs to the field of ton bag unloading technology, specifically involving a novel ton bag clamping mechanism. Background Technology

[0002] Against the backdrop of rapid development in modern industry, the application of large-ton bag packaging is becoming increasingly widespread, and enterprises are gradually replacing traditional manual unpacking and unloading with machinery.

[0003] However, the ton bag unloading stations currently on the market have obvious shortcomings. The design defects of the bag clamping mechanism result in the bag opening not being clamped securely, which easily leads to material leakage during unloading, causing waste and environmental pollution. The lack of dust removal devices results in serious dust problems during the unpacking process, which damages the production environment and threatens the health of workers. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a novel ton bag clamping mechanism is provided, including a frame, a clamping mechanism, a ton bag body, a winch, and a dust removal mechanism;

[0005] The lower surface of the ton bag body is provided with a ton bag outlet. A first crossbar is fixedly connected to one side surface of the upright frame, and a second crossbar is fixedly connected to the other side surface of the upright frame. A second cylinder is rotatably connected to the upper surface of the second crossbar, and a side support frame is rotatably connected to the side surface of the first crossbar.

[0006] The bag clamping mechanism includes two symmetrically arranged third cylinders and a clamping plate fixedly connected to the output end of the third cylinders. The dust removal mechanism includes a feeding cylinder, a connecting pipe, a dustproof box, a connecting pipe, a motor, and a rotating fan.

[0007] Through the above technical solution, the symmetrically arranged third cylinder drives the clamping plates to clamp the ton bag outlet, and the side support frame dynamically adjusts the support angle through the second cylinder to form a double-stabilized structure of "clamping + support". This effectively prevents leakage caused by uneven force on the bag opening. Moreover, the clamping response is faster when the two clamping plates move simultaneously. The side support frame supports the ton bag body and can prevent the ton bag body from falling from a height when the hoisting of the ton bag body fails, effectively ensuring the safety of the operator below. The dust removal mechanism creates negative pressure in the dust box by driving the rotating fan with a motor. The dust in the lower cylinder is adsorbed in real time through the connecting pipe, solving the problem of dust pollution from unpacking from the source.

[0008] The present invention is further configured such that a slide rail is provided on the lower surface of the upright frame, a hook is fixedly connected to the output end of the winch, a cross-shaped hanging plate is provided inside the hook, a first limiting plate is fixedly connected to the side surface of the cross-shaped hanging plate, and a second limiting plate is fixedly connected to the upper surface of the cross-shaped hanging plate.

[0009] Through the above technical solution, the slide rail allows the winch to move horizontally and accurately move the ton bag body directly above the feeding cylinder, avoiding misalignment between the bag opening and the clamping plate caused by manual alignment deviation, ensuring accurate clamping position, and the cross hanging plate is used to suspend the ton bag body.

[0010] The present invention is further configured such that the upper surface of the ton bag body is provided with an array of ton bag hanging rings, the ton bag hanging rings being located between the first limiting plate and the second limiting plate, and there is a 2 cm height difference between the first limiting plate and the second limiting plate.

[0011] The present invention is further configured such that a reinforcing rod is fixedly connected to the side surface of the upright, and an L-shaped support rod is fixedly connected to the side surface of the reinforcing rod. The upper surface of the L-shaped support rod is in contact with the dustproof box, and the L-shaped support rod and the dustproof box are fixedly connected by bolts.

[0012] Through the above technical solution, the reinforcing rod and the L-shaped support rod form a rigid support structure, which securely installs the dust box on the stand, avoiding the vibration generated when the motor drives the rotating fan, which may cause the parts to loosen or fall off. This ensures the long-term stable operation of the negative pressure dust removal system, guarantees the continuity of the dust removal effect, and avoids the dust collection efficiency being affected by equipment shaking.

[0013] The present invention is further configured such that the output end of the second cylinder is rotatably connected to the side support frame, the upper surface of the second crossbar is fixedly connected to the mounting frame, the side surface of the mounting frame is fixedly connected to the connecting frame, the inner side wall of the connecting frame is provided with a limiting groove, the lower surface of the connecting frame is fixedly connected to the feeding cylinder, the third cylinder is fixedly connected to the side surface of the connecting frame, and the clamping plate is located in the limiting groove.

[0014] Through the above technical solution, the second cylinder drives the side support frame to rotate, and the support angle can be adjusted in real time according to the weight of the ton bag and the unloading status to counteract the lateral tension of the ton bag during unloading. The limiting groove constrains the movement trajectory of the clamping plate, avoiding insufficient local clamping force at the bag mouth caused by the clamping plate being tilted, making the bag mouth seal more uniform and further enhancing the anti-leakage effect.

[0015] The present invention is further configured such that a mounting plate is fixedly connected to the side surface of the support frame, a first cylinder is fixedly connected to the side surface of the mounting plate, and a semi-circular push head is fixedly connected to the output end of the first cylinder.

[0016] Through the above technical solution, the semi-circular push head strikes the ton bag body, breaking up material clumps and adsorption to the bag wall, ensuring smooth material discharge. At the same time, the rapid material discharge can shorten the unloading time, reduce the duration of continuous dust generation, and indirectly improve dust removal efficiency.

[0017] The present invention is further configured such that the feeding cylinder is fixedly connected to the connecting frame, a protective door is provided on the side surface of the feeding cylinder, the connecting pipe is provided on the side surface of the feeding cylinder, and the dustproof box is connected to the connecting pipe through the connecting pipe.

[0018] With the above technical solution, the protective door can be opened to facilitate personnel to remove the cable ties on the ton bag outlet, and when closed, it forms a closed dust removal space, and the negative pressure airflow directly introduces the dust into the dust box through the connecting pipe.

[0019] The present invention is further configured such that the motor is fixedly connected to the upper surface of the dustproof box, the rotating fan is fixedly connected to the output end of the motor, a mesh is fixedly connected to the inner side wall of the dustproof box near the rotating fan, a door is provided on the side surface of the dustproof box, and a controller is fixedly connected to the side surface of the upright.

[0020] The beneficial effects of this utility model are as follows:

[0021] The structure, which uses two third cylinders to drive two clamping plates, clamps the ton bag outlet evenly in opposite directions. Combined with the dynamic support adjustment of the side support frame, a multi-angle stable clamping system is formed, which effectively prevents material leakage during unloading, reduces material waste and environmental pollution. At the same time, the motor drives the rotating fan to create negative pressure inside the dustproof box, and the dust in the discharge cylinder is adsorbed in real time through the connecting pipe, achieving the dust removal effect. This solves the problem of dust from unpacking at the source, maintaining a clean production environment and protecting the respiratory health of workers. Attached Figure Description

The ton bag hanging ring 61 is located between the first limiting plate 51 and the second limiting plate 52. There is a height difference of 2 cm between the first limiting plate 51 and the second limiting plate 52.

A semi-circular push head 81 is fixedly connected to the output end of the first cylinder 8. The semi-circular push head 81 can continuously knock the ton bag body 6 under the drive of the first cylinder 8, breaking the internal material clumps and adsorption to the bag wall, helping the material to be discharged smoothly. At the same time, the rapid discharge of material can shorten the unloading time, reduce the duration of continuous dust generation, and indirectly improve dust removal efficiency.

[0033] The lower surface of the ton bag body 6 is provided with a ton bag outlet 62. A first crossbar 101 is fixedly connected to one side surface of the upright frame 1, and a second crossbar 102 is fixedly connected to the other side surface of the upright frame 1. A second cylinder 9 is rotatably connected to the upper surface of the second crossbar 102. A side support frame 10 is rotatably connected to the side surface of the first crossbar 101. The output end of the second cylinder 9 is rotatably connected to the side support frame 10. The second cylinder 9 drives the side support frame 10 to rotate, and the support angle can be adjusted in real time according to the weight of the ton bag body 6 and the unloading status to counteract the lateral tension of the ton bag body 6 during unloading.

[0034] The upper surface of the second crossbar 102 is fixedly connected to the mounting bracket 11, the side surface of the mounting bracket 11 is fixedly connected to the connecting frame 12, the inner side wall of the connecting frame 12 is provided with a limiting groove 13, the lower surface of the connecting frame 12 is fixedly connected to the feeding cylinder 16, the third cylinder 14 is fixedly connected to the side surface of the connecting frame 12, the clamping plate 15 is located in the limiting groove 13, the limiting groove 13 constrains the movement trajectory of the clamping plate 15, avoids insufficient local clamping force at the bag opening caused by the clamping plate 15 being tilted, makes the bag opening seal more uniform, and further enhances the anti-leakage effect.

[0035] The bag clamping mechanism includes two symmetrically arranged third cylinders 14 and a clamping plate 15 fixedly connected to the output end of the third cylinders 14. The dust removal mechanism includes a feeding cylinder 16, a connecting pipe 162, a dustproof box 17, a connecting pipe 18, a motor 19, and a rotating fan 20. A reinforcing rod 103 is fixedly connected to the side surface of the upright frame 1. An L-shaped support rod 104 is fixedly connected to the side surface of the reinforcing rod 103. The upper surface of the L-shaped support rod 104 contacts the dustproof box 17. The L-shaped support rod 104 and the dustproof box 17 are fixedly connected by bolts. The reinforcing rod 103 and the L-shaped support rod 104 form a rigid support structure. The dustproof box 17 is securely installed by bolts.

[0036] The feeding cylinder 16 is fixedly connected to the connecting frame 12. A protective door 161 is provided on the side surface of the feeding cylinder 16. After the protective door 161 is opened, it is convenient for personnel to remove the cable ties on the ton bag outlet 62. After closing, a closed dust removal space is formed. The negative pressure airflow directly introduces the dust into the dustproof box 17 through the connecting pipe 162. The connecting pipe 162 is located on the side surface of the feeding cylinder 16. The dustproof box 17 and the connecting pipe 162 are connected through the connecting pipe 18. The motor 19 is fixedly connected to the upper surface of the dustproof box 17, and the rotating fan 20 is fixedly connected to the motor 19. At the output end, a mesh 21 is fixedly connected to the inner side wall of the dust box 17 near the rotating fan 20. The motor 19 drives the rotating fan 20 to rotate at high speed, creating a negative pressure inside the dust box 17. The dust in the feed cylinder 16 is strongly adsorbed through the connecting pipe 162. The mesh 21 intercepts the dust and prevents the rotating fan 20 from being entangled by foreign objects, ensuring continuous and efficient dust removal. A door is provided on the side surface of the dust box 17. After the dust in the dust box 17 has been collected for a long time, the door can be opened for cleaning. A controller is fixedly connected to the side surface of the stand 1.

[0037] The symmetrically arranged third cylinder 14 drives the clamping plate 15 to clamp the ton bag outlet 62 in opposite directions. Together with the side support frame 10, the support angle is dynamically adjusted by the second cylinder 9 to form a "clamping + support" double stable structure, which effectively prevents leakage caused by uneven force on the bag opening. Moreover, the clamping response is faster when the two clamping plates 15 move at the same time. The side support frame 10 supports the ton bag body 6 and can prevent the ton bag body 6 from falling from a height when the hoisting of the ton bag body 6 fails, effectively ensuring the safety of the operator below. The dust removal mechanism drives the rotating fan 20 through the motor 19 to form a negative pressure in the dust box 17. The dust in the discharge cylinder 16 is adsorbed in real time through the connecting pipe 162, solving the problem of dust pollution from unpacking from the source.

[0038] The working principle of this utility model is as follows: When the ton bag body 6 is suspended above the connecting frame 12, the winch 3 is started to lower the ton bag body 6 and place the ton bag outlet 62 into the feeding cylinder 16. The second cylinder 9 is started to rotate the side support frame 10 and adjust the support angle of the side support frame 10 on the ton bag body 6. The third cylinder 14 is started to push out the clamping plate 15. The two opposing clamping plates 15 clamp the ton bag outlet 62. At this time, the operator opens the protective door 161 to release the cable ties on the ton bag outlet 62 located below the clamping plate 15, and then closes the protective door 161. 61. When unloading is required, simply activate the third cylinder 14 to move the two clamping plates 15 away from the outlet 62 of the ton bag, and the material inside the ton bag body 6 will be discharged. During the discharge process, the first cylinder 8 can be activated continuously to make the semi-circular push head 81 knock on the ton bag body 6, helping the material inside the ton bag body 6 to be completely discharged. During the unloading process, the motor 19 is activated to make the rotating fan 20 rotate, creating a negative pressure inside the dustproof box 17. The dust in the discharge cylinder 16 is sucked into the dustproof box 17 through the connecting pipe 162. After the dust in the dustproof box 17 has accumulated for a period of time, the box door can be opened for cleaning.
