Description

Technical Field

[0001] This utility model belongs to the technical field of sulfur processing equipment, specifically relating to a device for sulfur packaging. Background Technology

[0002] Sulfur is an important chemical raw material, widely used in chemical, agricultural, and pharmaceutical fields. In the production and processing of sulfur, granules or powder need to be packaged in bags for storage and transportation. Currently, this is mainly done by workers weighing the sulfur, pouring the weighed sulfur into packaging bags, and finally sealing them. This manual packaging of sulfur requires long hours of repetitive work, leading to fatigue, high labor intensity, and low packaging efficiency. Furthermore, the accuracy and stability of manual operation are poor, easily resulting in inconsistent bag weights and affecting product quality. Utility Model Content

[0003] The problem solved by this utility model is to provide a sulfur packaging device to address the issues of high labor intensity, low packaging efficiency, and inconsistent bag weights in existing manual sulfur bagging methods.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a hopper, a weighing hopper, a hook-off device, a packaging bag, and a PLC controller. The bottom of the hopper is connected to the weighing hopper. A feed control valve is provided at the lower part of the hopper. The hook-off device is located below the weighing hopper. The packaging bag is hooked onto the hook-off device. The outlet of the weighing hopper extends into the packaging bag. A bag clamping device is provided below the hook-off device. The feed control valve, the weighing hopper, the hook-off device, and the... All the bag clamping devices are connected to the PLC controller. The PLC controller is used to control the feed control valve, the weighing hopper, the unhooking device, and the bag clamping device. The hopper is used to buffer the material before it enters the weighing hopper. The feed control valve is used to control the amount and accuracy of the material falling from the hopper into the weighing hopper. The weighing hopper is used to weigh the material before it enters the packaging bag to ensure that the weight of each bag is consistent. The bag clamping device is used to clamp the filling port of the packaging bag for sealing.

[0005] A more specific technical solution in the above technical solution is as follows: the upper part of the silo is connected to the material pipe, the material pipe is equipped with a gate valve, the silo is equipped with a material level sensor, the material level sensor and the gate valve are both connected to the PLC controller, and the PLC controller is used to receive the signal from the material level sensor and control the gate valve.

[0006] Furthermore, it also includes a dust collector, a dust cover, and a fan. The dust cover is located between the weighing hopper and the silo. The dust collector is connected to the dust cover and the fan. The fan is connected to the PLC controller, which controls the fan. The dust collector collects the dust generated during the process of material falling from the silo into the weighing hopper.

[0007] Furthermore: the dust collector and the dust cover are connected by a dust collection pipe, and the dust collector and the fan are connected by an exhaust pipe.

[0008] Furthermore, it also includes an indoor silencer connected to the fan, which is used to reduce the noise generated by the fan when it is operating indoors.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: It receives signals from the weighing hopper via a PLC controller and controls the material discharge from the hopper, then controls the bag clamping device to seal the packaging bags containing the material, thus achieving automatic weighing and packaging of sulfur. This significantly reduces manual labor intensity and the direct contact time between operators and sulfur, thereby reducing the harm to operators' health, while ensuring the consistency of the weight of each bag of sulfur. It features low manual labor intensity, high packaging efficiency, and consistent bag weight. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and examples:

[0013] like Figure 1The sulfur packaging device shown includes a hopper 1, a weighing hopper 2, a hook release device 3, packaging bags 9, and a PLC controller. The bottom of the hopper 1 is connected to the weighing hopper 2. A feed control valve 11 is located at the bottom of the hopper 1. The hook release device 3 is located below the weighing hopper 2. The packaging bags 9 are hooked onto the hook release device 3. The outlet of the weighing hopper 2 extends into the packaging bags 9. A bag clamping device 4 is located below the hook release device 3. The feed control valve 11, weighing hopper 2, hook release device 3, and bag clamping device 4 are all connected. All four components are connected to a PLC controller. The PLC controller controls the feed control valve 11, weighing hopper 2, unhooking device 3, and bag clamping device 4. The hopper 1 serves as a buffer before material enters the weighing hopper 2. The feed control valve 11 controls the amount and accuracy of material falling from the hopper 1 into the weighing hopper 2. The weighing hopper 2 weighs the material before it enters the packaging bag 9 to ensure consistent bag weight. The bag clamping device 4 clamps and seals the filling port of the packaging bag 9. The upper part of the hopper 1 is connected to the material pipe 8, which is equipped with a gate valve 81. The hopper 1 is equipped with a level sensor. Both the level sensor and the gate valve 81 are connected to the PLC controller, which receives signals from the level sensor and controls the gate valve 81. It also includes a dust collector 5, a dust cover 51, and a fan 6. The dust cover 51 is located between the weighing hopper 2 and the silo 1. The dust collector 5 is connected to the dust cover 51 and the fan 6. The fan 6 is connected to a PLC controller, which controls the fan 6. The dust collector 5 collects the dust generated during the process of material falling from the silo 1 into the weighing hopper 2. The dust collector 5 and the dust cover 51 are connected by a dust collection pipe 52, and the dust collector 5 and the fan 6 are connected by an exhaust pipe 61. It also includes an indoor silencer 7, which is connected to the fan 6 and is used to reduce the noise generated by the fan 6 during indoor operation.

[0014] In use, the worker hooks the packaging bag 9 onto the unhooking device 3, turns on the PLC controller to open the gate valve 81 and start the fan 6, and the sulfur falls from the feed pipe 8 into the hopper 1. When the level sensor senses that the hopper is almost full of sulfur, the PLC controller closes the gate valve 81 and then controls the feed control valve 11 to open. The dust collector 5 collects the dust from the sulfur falling into the weighing hopper 2. When the weight of the sulfur in the weighing hopper 2 reaches the set parameter, the PLC controller closes the feed control valve 11 and then controls the weighing hopper 2 to unload all the sulfur into the packaging bag 9. Then, the bag clamping device 4 clamps the filling port of the packaging bag 9 to seal it. Then, the unhooking device 3 releases the hook and lowers the packaging bag 9 containing sulfur. Finally, the worker can use a cantilever crane or conveyor belt to transport the packaged sulfur to another location.

[0015] It should be noted that the PLC controller, weighing hopper 2, unhooking device 3, bag clamping device 4, dust collector 5, and indoor silencer 7 provided in this utility model are all common devices in the prior art. They only need to be connected according to the connection relationship given in the embodiment of this utility model, and the technical solution of this utility model can be obtained by conventionally setting up the PLC controller. It does not involve any improvement in control methods or software. As for the parameter setting and usage method of the PLC controller, those skilled in the art can purchase the PLC controller and refer to the accompanying instruction manual to set up the corresponding control, and will not be described in detail here.
