Abstract

The invention relates to a pumping type valve bag packing machine. The pumping type valve bag packing machine is composed of a diaphragm pump, a stop valve, a weighing device, an air control box and a control cabinet. The diaphragm pump and the stop valve are fixedly mounted on a machine frame of the packing machine. A feeding opening is formed in the upper end of the diaphragm pump, a discharging opening is formed in the lower end of the diaphragm pump, and the discharging opening is connected with the stop valve. The weighing device is connected to the side face of the machine frame, and the air control box and the control cabinet are connected to the lower portion of the machine frame. Compared with the prior art, materials can be actively filled into a valve bag through the diaphragm pump, so that energy consumption is low, precision is high, the outer surface of the bag is clean, and full-automatic packing can be realized.

Description

technical field

[0001] The invention relates to the packaging industry, in particular to a pumping valve bag packaging machine. Background technique

[0002] As packaging machines are used more and more widely, there are thousands of materials in the packaging industry. For unused materials, packaging machines need to adopt different conveying forms. Especially some lightweight materials are difficult to pack in valve pockets. Most of the lightweight powder packaging machines on the market now use vacuum packaging technology. Vacuum packaging requires a lot of energy consumption, low packaging capacity, poor precision, high air permeability of the packaged valve pockets, and it is difficult to achieve fully automatic packaging.

[0003] Chinese patent CN 103496456A discloses a valve bag packaging machine, which includes a frame with a storage bin, a feed hopper is provided at the inlet of the storage bin, and a valve bag filler is provided at the outlet of the storage bin....

Embodiment

[0021] A pumping type valve bag packaging machine, its structure is as follows figure 1 As shown, it consists of a diaphragm pump 1, a stop valve 2, a weighing device 4, an air control box 5 and a control cabinet 6. The diaphragm pump 1 and the stop valve 2 are fixedly installed on the frame 3 of the packaging machine. The upper end of the diaphragm pump 1 It is the material inlet, the lower end is the material outlet, the material outlet is connected with the shut-off valve 2, the weighing device 4 is connected to the side of the frame 3, and the air control box 5 and the control cabinet 6 are connected to the bottom of the frame 3. The cut-off valve 2 is controlled by a double-stroke cylinder to perform coarse feeding and fine feeding respectively.

[0022] The weighing device 4 is provided with a feeding nozzle, and the feeding nozzle is covered with a valve pocket. The shut-off valve 2 controls the delivery of the material delivered by the diaphragm pump 1 to the valve po...
