Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a pneumatic sealing machine. Background Art

[0002] A loading device is a device used to transport materials or items to a specific location or equipment. When selecting a suitable loading device, it is necessary to consider the properties of the material, such as size, shape, and weight, the requirements of the production process, such as speed and accuracy, and the conditions of the working environment, such as space limitations and hygiene requirements. For application scenarios such as pneumatic sealing machines, since different sealing machines are required to encapsulate different materials, the loading device to be selected should also match them, so as to increase the sealing efficiency of the sealing machine.

[0003] Existing sealing machines for packaging granular materials often need to be matched with a feeding device that can conveniently transport granular materials. However, the existing feeding devices for granular materials lack a quantitative conveying structure, resulting in the feeding process requiring manual monitoring and operation of the starting and stopping of the feeding device, which is time-consuming and labor-intensive.

[0004] Therefore, those skilled in the art provide a pneumatic sealing machine feeding device to solve the problems raised in the above background technology. Utility Model Content

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A pneumatic sealing machine feeding device comprises a storage bin, and a quantitative conveying mechanism is provided below the storage bin;

[0008] The quantitative conveying mechanism includes a feeding pipe, the bottom end of the feeding pipe is fixedly connected to a weighing cylinder, the outer surface of the weighing cylinder is fixedly connected to a button controller and a support frame, the inner wall of the support frame is fixedly connected to an electric telescopic rod, the inner wall of the feeding pipe is fixedly connected to a driving motor, the output end of the driving motor is fixedly connected to an active rod, the outer surface of the active rod is fixedly connected to a butterfly valve core, the inside of the weighing cylinder is slidably connected to a baffle, and the inner wall of the baffle is fixedly connected to a pressure sensor.

[0009] As a further solution of the present invention: the top end of the feeding pipe is fixedly connected to the bottom end of the storage bin, the back end of the baffle is fixedly connected to the telescopic end of the electric telescopic rod, the electric telescopic rod, pressure sensor and drive motor are all electrically connected to the button controller through wires, the outer surface of the storage bin is fixedly connected to a support ring frame, and two groups of support legs are provided on the outside of the storage bin, and the top end of each group of support legs is fixedly connected to the bottom surface of the support ring frame.

[0010] As a further solution of the present invention: the bottom end of the weighing cylinder is fixedly connected to the discharge cylinder, a feeding hose is provided below the weighing cylinder, and the top end of the feeding hose is fixedly connected to the bottom end of the discharge cylinder.

[0011] As a further solution of the present invention: a coupling is fixedly connected to the outer surface of the output end of the driving motor, and the inner wall of the coupling is fixedly connected to the outer surface of the active rod.

[0012] As a further solution of the present invention: two auxiliary bearings are fixedly connected to the inner wall of the feeding pipe, and the inner ring of each auxiliary bearing is fixedly connected to the outer surface of the active rod.

[0013] As a further solution of the present invention: a dust plug is clamped inside the storage bin, and a plurality of identical air-permeable cavities are opened inside the dust plug.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model cooperates with a storage bin, a feeding pipe, a weighing cylinder, a button controller, a support frame, an electric telescopic rod, a baffle, a pressure sensor, a driving motor, an active rod and a butterfly valve core. Small granular materials can be stored in the storage bin. The speed of the driving motor and the weight required to be monitored by the pressure sensor can be controlled by operating the button controller. Then, the button controller is operated to control the driving motor to drive the active rod and the butterfly valve core to rotate after power is turned on. The small granular materials in the storage bin are slowly turned over by the butterfly valve core through the feeding pipe and enter the weighing cylinder until the weight of the small granular materials on the pressure sensor reaches the set value of the button controller. The button controller automatically controls the driving motor to cut off power and stop rotation. The button controller then controls the electric telescopic rod to contract and take the baffle and the pressure sensor away from the inside of the weighing cylinder. The small granular materials on the pressure sensor pass through the bottom of the weighing cylinder and finally flow into the packaging inside the pneumatic sealing machine, thereby quantitatively conveying small granular materials to the pneumatic sealing machine, avoiding the problem that the loading process requires manual monitoring and operation of the start and stop of the loading device due to the lack of a quantitative conveying structure, which is time-consuming and labor-intensive.

By providing the discharge cylinder 9, the weighed material in the weighing cylinder 202 can be discharged downward. By providing the feeding hose 10, it is convenient to discharge the material coming out from the bottom of the discharge cylinder 9 in multiple directions.

By providing the coupling 5, the connection between the output end of the driving motor 208 and the active rod 209 can be strengthened, thereby increasing the rotational stability of the active rod 209.

[0026] The outer surface of the active rod 209 is fixedly connected to the butterfly valve core 210, the inside of the weighing cylinder 202 is slidably connected to the baffle 206, the back of the baffle 206 is fixedly connected to the telescopic end of the electric telescopic rod 205, and the inner wall of the feeding tube 201 is fixedly connected to two auxiliary bearings 6.

The dust plug 7 can effectively prevent external impurities of the storage bin 1 from entering the interior of the storage bin 1. At the same time, the breathable cavity 8 is provided to balance the air pressure inside and outside the storage bin 1, thereby increasing the material below.

[0028] The working principle of the present invention is: when in use, take out the dust plug 7 from the storage bin 1 and introduce a sufficient amount of granular material into the storage bin 1, then operate the button controller 203 to adjust the speed of the drive motor 208 and the weight required for weighing and monitoring by the pressure sensor 207, then place the feeding hose 10 on or in the package on the pneumatic sealing machine, then operate the button controller 203 to start the drive motor 208 and start to drive the active rod 209 and the butterfly valve core 210 to rotate and the pressure monitoring of the pressure sensor 207, then the granular material in the storage bin 1 is gradually driven by the flipping of the butterfly valve core 210 through the feeding pipe 201 and placed on the pressure sensor 207 in the weighing cylinder 202, until the weight of the granular material on the pressure sensor 207 reaches the set value of the button controller 203, the button controller 203 will automatically control the drive The motor 208 is powered off to stop the butterfly valve core 210 from lowering the material in the storage bin 1, and then the button controller 203 controls the electric telescopic rod 205 to be powered on and start to retract until the baffle 206 completely leaves the inside of the weighing cylinder 202.
