Description

Technical Field

[0001] This utility model relates to the field of conveying and packaging equipment technology, and specifically to a bulk-to-ton-bag switching device. Background Technology

[0002] Existing equipment typically only supports bulk packaging and lacks ton bag functionality. When the demand requires the use of ton bags (large container bags) for packaging resin paste, it cannot directly meet the customer's needs. Manual packaging is usually used, which is inefficient. Moreover, traditional ton bag operation may face problems such as material blockage, insufficient weighing accuracy, and excessive manual intervention. This utility model proposes a new solution to the above problems. Utility Model Content

[0003] To overcome at least one of the aforementioned drawbacks, this utility model provides a bulk-package to ton-package switching device. The objective of this utility model can be achieved by adopting the following technical solution:

[0004] This application provides a bulk-to-ton-bag switching device, comprising:

[0005] Main feed pipe, the main feed pipe being used to transport paste resin material;

[0006] Branch pipe, which is connected to the main material pipe, is used to divert material to ton bags;

[0007] A hopper, which is connected to the outlet of the branch pipe, is used to temporarily store materials;

[0008] A blower, which is connected to the silo, uses airflow to fluidize the material;

[0009] A ton bag, the open end of which is connected to the outlet of the hopper;

[0010] Hooks, used to secure ton bags;

[0011] A weighing scale, which is connected to the hook, monitors the weight of the ton bag in real time;

[0012] A conveying device is located below the ton bag and automatically transports the ton bag after packaging is completed.

[0013] In one possible implementation, a gate valve is provided downstream of the connection between the main material pipe and the branch pipe, as well as on the branch pipe, for switching the material flow direction.

[0014] In one possible implementation, the main material pipe includes a bulk packaging outlet, and the bulk packaging mode and ton packaging mode are quickly switched through the gate valve.

[0015] In one possible implementation, the inlet and outlet of the silo are equipped with pneumatic regulating valves.

[0016] In one possible implementation, the fan's air pressure is adjustable to adapt to the fluidization requirements of different materials.

[0017] In one possible implementation, the length of the hook is adjustable to accommodate ton bags of different sizes.

[0018] In one possible implementation, the conveying device includes several conveyor belts connected end to end.

[0019] In one possible implementation, it further includes:

[0020] The outer shell can be a frame, which is fitted over the outside of the ton bag, and the hook and the weighing scale are both mounted on the frame.

[0021] The beneficial technical effects of this utility model are as follows: According to the present disclosure, the bulk-to-ton-bag switching device includes a main material pipe, a branch pipe, a hopper, a blower, ton bags, hooks, a weighing scale, and a conveying device. Through the coordinated design of the main material pipe and the branch pipe, seamless switching between bulk and ton bag functions is achieved. While retaining the original bulk bag capacity, the ton bag loading capacity is expanded to meet diverse packaging needs.

[0028] This application provides a device for switching from bulk packages to ton packages, such as... Figure 1 As shown, the system includes a main material pipe 1, a branch pipe 2, a hopper 4, a blower 5, a ton bag 10, a hook 7, a weighing scale 9, and a conveying device 11. The main material pipe 1 is used to transport the paste resin material. The branch pipe 2 is connected to the main material pipe 1 and is used to divert the material to the ton bags. The hopper 4 is connected to the outlet of the branch pipe 2 and is used to temporarily store the material. The blower 5 is connected to the hopper 4 and uses airflow to fluidize the material. The open end of the ton bag 10 is connected to the outlet of the hopper 4. The hook 7 is used to fix the ton bag 10. The weighing scale 9 is connected to the hook 7 to monitor the weight of the ton bag 10 in real time. The conveying device 11 is located below the ton bag 10 and automatically transports the ton bag 10 after packaging.

[0029] The bulk-to-ton-bag switching device provided in this embodiment achieves seamless switching between bulk and ton-bag functions through the coordinated design of the main material pipe 1 and the branch pipe 2. It retains the original bulk capacity while expanding the ton-bag loading function to meet diverse packaging needs. On the basis of retaining the original bulk function, it adds ton-bag loading capacity, realizing dual-purpose functionality and meeting the diverse needs of customers for different packaging forms.

[0030] The bulk-to-ton-bag switching device provided in this embodiment forms a fluidized processing system through the linkage of the hopper 4 and the fan 5, which effectively prevents material bridging and ensures continuous and stable feeding. The hook 7 and the weighing scale 9 realize dynamic monitoring and adjustment of the ton-bag weight. No manual intervention is required throughout the process, which improves packaging accuracy. The automatic conveying function of the conveying device 11 is seamlessly connected with the packaging process, reducing material transfer time and forming an integrated closed loop of packaging-weighing-conveying.

[0031] In one possible implementation, a gate valve 3 is provided downstream of the connection between the main material pipe 1 and the branch pipe 2, and on the branch pipe 2, for switching the material flow direction.

[0032] Among them, the downstream of the connection between the main material pipe 1 and the branch pipe 2 and the branch pipe 2 are both equipped with a double layout design of gate valve 3. The dual valves work together to ensure that the material flows only to the designated pipe branch, preventing backflow or chaotic flow, improving the controllability of switching operations, retaining the original bulk packaging capacity while expanding the ton packaging capacity, and meeting the diverse needs of customers for different packaging forms.

[0033] In one possible implementation, the main material pipe 1 includes a bulk package outlet, and a slide gate valve 3 enables rapid switching between bulk package mode and ton package mode.

[0034] Among them, the slide gate valve 3 ensures that there is no material residue or cross-contamination between the bulk package outlet and the ton package branch through a physical shut-off mechanism. When the valve is closed, it forms multiple sealing barriers, effectively blocking the mutual seepage of materials between the main / branch pipes 2, ensuring purity during mode switching, and maintaining a high-cleanliness production environment.

[0035] In one possible implementation, the inlet and outlet of the silo 4 are equipped with pneumatic regulating valves 6, which can precisely adjust the valve core opening to achieve dynamic control of the material inlet and outlet rate and avoid overfilling or emptying the silo 4.

[0036] In one possible implementation, the air pressure of the blower 5 is adjustable, dynamically matching the critical fluidization pressure threshold of materials with different particle sizes, adapting to the fluidization requirements of different materials, adjusting the output pressure according to material characteristics (density, humidity, etc.), eliminating ineffective energy loss, avoiding under-fluidization (material deposition) or over-fluidization (material splashing) phenomena, and ensuring uniform conveying.

[0037] In one possible implementation, the length of the hook 7 is adjustable to fit ton bags 10 of different sizes. Multiple hooks 7 are used to hook onto multiple points at the opening of the ton bag 10 to achieve fixation, ensuring the stability of the opening of the ton bag 10 and allowing materials to enter the ton bag 10 through the opening.

[0038] The hook 7 can be a remote control switch or an automatic switch based on the weighing scale 9. When the ton bag 10 is filled with material, that is, when the weighing scale 9 detects that the weight of the ton bag 10 meets the standard, the hook 7 can be operated to automatically release the ton bag 10 and place it on the conveying device 11.

[0039] In one possible implementation, the conveying device 11 includes a plurality of conveyor belts connected end to end.

[0040] The ton bag 10 is located above the conveyor belt, and after the ton bag 10 is filled, it is placed on the conveyor belt for transportation.

[0041] In one possible implementation, the bulk-to-ton-bag switching device also includes a housing 8, which can be a frame that is fitted over the outside of the ton-bag 10. The hook 7 and the weighing scale 9 are both mounted on the frame.

[0042] The frame, as a rigid carrier, integrates the lifting load of hook 7 with the force path of the weighing sensor, eliminating the measurement reference error caused by vibration in the split structure.
