[0034] (Example)

[0035] See Figure 1 A fully automatic upper weighing filling machine comprises a machine frame 1, a material tank 2 fixed on the upper part of the machine frame 1, a control cabinet 3 fixed on the side of the machine frame 1, a plurality of quantitative filling mechanisms 4 fixed inside the machine frame 1, a material barrel conveyor 5 passing through the machine frame 1, and a material unloading control device 6 installed inside the machine frame 1;

[0036] See Figure 2, the quantitative filling mechanism 4 includes a weighing sensor 4-1 and a buffer tank 4-2, a pump 4-3 and a discharge nozzle 4-4 which are connected in sequence through pipelines. The buffer tank 4-2 is connected to the material tank 2 through a pipeline, and a pneumatic valve 2-1 is arranged between the material tank 2 and the buffer tank 4-2. The weighing sensor 4-1 is fixedly connected to the bottom of the buffer tank 4-2, and the pipelines connecting the buffer tank 4-2 and the pump 4-3 are both hoses, and a manual valve 4-5 is arranged in front of the pump, and the barrel conveyor 5 is located below the discharge nozzle 4-4; wherein the pump 4-3 can adjust the speed, and can be a rotor pump, a gear pump or a centrifugal pump; a plurality of shock absorbers (not shown in the figure) are arranged between the pump 4-3 and the machine frame 1, and the shock absorber model is a bell-shaped rubber shock-absorbing pad 60kg-M12304.

[0037] See Figure 3 and Figure 4 The material discharge control device 6 includes a motor 6-1 fixed on the top of the machine frame 1, a driving shaft 6-2 that passes through the motor 6-1 and is parallel to the conveying direction of the bucket conveyor 5, a lifting mechanism 6-3 located below the driving shaft 6-2 and symmetrically connected to both ends of the driving shaft 6-2, a cross bar 6-4 located above the material discharge nozzle 4-4 and fixedly connected to the lifting mechanisms 6-3 at both ends, and a plurality of material discharge control rods 6-5 vertically fixed to the cross bar 6-4; upper gears 6-2-1 are fixed at both ends of the driving shaft 6-2, and the lifting mechanism 6-3 includes a gear 6-2-1 fixed to the machine frame 1 and perpendicular to the driving shaft The sliding bar 6-3-1 of 6-2, the sliding block 6-3-2 movably connected with the sliding bar 6-3-1, the lower gear 6-3-3 fixed on the sliding bar 6-3-1, and the chain 6-3-4 sleeved on the upper gear 6-2-1 and the lower gear 6-3-3; the chain 6-3-4 is fixedly connected with the sliding block 6-3-2, and the sliding block 6-3-2 is fixedly connected with one end of the cross bar 6-4; the material discharge control rod 6-5 penetrates the material discharge nozzle 4-4 along the inner hole direction of the material discharge nozzle 4-4, and a blocking ball 6-5-1 is provided at one end of the material discharge control rod 6-5 penetrating the material discharge nozzle 4-4.

[0038] The unloading control device 6 drives the upper gear 6-2-1 of the driving shaft 6-2 to rotate through the motor 6-1, and the upper gear 6-2-1 drives the chains 6-3-4 on both sides to move upward or downward synchronously, and further drives the cross bar 6-4 fixed on the chain 6-3-4 to move up and down, and drives multiple unloading control rods 6-5 fixed on the cross bar to move up and down synchronously, and synchronously controls the switches of multiple unloading nozzles.

[0039] In this embodiment, the pneumatic valve 2-1, the weighing sensor 4-1, the pump 4-3, the barrel conveyor 5 and the motor 6-1 are all electrically connected to the control cabinet 3, which can automatically control the filling work and improve the work efficiency and accuracy.

[0040] For ease of understanding, the filling action of this embodiment is as follows:

[0041] Step 1: The control cabinet 3 opens the pneumatic valve 2-1 to allow the material in the material tank 2 to flow into the buffer tank 4-2;

[0042] Step 2: When the material in the buffer tank 4-2 reaches the set value of the weighing sensor 4-1, the weighing sensor 4-1 sends a signal, and the control cabinet 3 controls the pneumatic valve 2-1 to close;

[0043] Step 3, the motor 6-1 is started, and the material discharge control rod 6-5 is controlled to descend to the position, and then the material discharge nozzle 4-4 is opened, and at the same time, the pump 4-3 is started to enter the fast mode and start filling;

[0044] Step 4: When the weighing sensor 4-1 is close to the set value, the weighing sensor 4-1 sends a signal, and the control cabinet 3 controls the pump to enter the slow mode to control the flow rate of the material to be stable;

[0045] Step 5, when the weighing sensor 4-1 reaches the set value, the discharge nozzle 4-4 is closed, and the pump 4-3 is closed at the same time, the motor 6-1 controls the discharge control rod 6-5 to rise, and the blocking ball blocks the outlet of the discharge nozzle 4-4.

[0046] In this embodiment, the high flow rate of the filling machine is controlled by a pump. Depending on the material, the pump can be a rotor pump, a gear pump, or a centrifugal pump. Before the weighing sensor approaches the set value, the control cabinet controls the pump to switch to slow mode, which can control the flow rate of the material to be stable, thereby achieving accurate measurement. A manual valve is added in front of the pump to control the flow rate of the pump. Furthermore, multiple sections of flexible hoses are used between the pump and the sensor, and multiple shock absorbers are used between the motor and the entire machine frame to prevent vibration, which can effectively ensure that the accuracy of the sensor is not affected by the pump motor, thereby improving the accuracy.

[0047] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
