Utilize the difference of pressure between vacuum packing chamber and the feed bin powder product to be sucked the packaging bag that places vacuum packing chamber, be implemented under the enclosed vacuum state powder is packed, baffle plate in the packer's bay can be adjusted according to the packaging bag size, in the later stage of packing, carry out dedusting by dust collecting, whole packaging process also can be controlled package weight by weighting apparatus, therefore pack and weigh and finish simultaneously, the package weight that has overcome the conventional bag installation is little, the dust pollution important disadvantages, packaging efficiency and measuring accuracy height, the packing of product is closely knit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model vacuum packing chamber;
Fig. 3 is the structural representation of middle feed nozzle shown in Figure 2.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment is made of support, feeding device, vacuum packing chamber, dust collecting and weighting apparatus.Vacuum-pumping tube 2, vacuum releasing tube 3 and feed nozzle 25 are installed in the vacuum packing chamber 1, and vacuum-pumping tube is connected to vacuum pump, and a valve 13 is installed on vacuum-pumping tube 2, and during wrapping machine work, valve 13 is opened, and vacuum packing chamber 1 is vacuumized; Vacuum releasing tube 3 communicates with atmosphere and a valve 12 also is installed in pipe, the vacuum releasing tube is the stability that is used for guaranteeing vacuum-packed indoor degree of vacuum, when the indoor degree of vacuum of vacuum packaging is too high, valve 12 is opened the degree of vacuum that makes in the vacuum packing chamber 1 and is descended, then close when degree of vacuum is low, guarantee the stable of vacuum-packed room pressure like this.
Feed nozzle 25 is positioned at the top of the above-mentioned tetragonal body that is surrounded by baffle plate and bracing frame and is fixed on the seal chamber, feed nozzle 25 is arranged in a vacuum-packed outdoor end and is connected with the feed pipe 4 of feed arrangement, it is that powder enters the inlet of packaging bag and is used to hitch packaging bag that feed nozzle is positioned at a vacuum-packed indoor end, when laying packaging bag the valve port of valve port packaging bag is inserted in feed nozzle and gets final product.As shown in Figure 3, the middle part of feed nozzle is provided with expandable rubber ring 26, has aperture 27 on the nozzle barrel that rubber ring 26 is wrapped up, and aperture can link to each other with compressed air inlet 29 through connecting tubule 28.When wrapping machine was worked, the compressed air inlet entered pressurized air, and rubber ring then expands, and played the effect of fixing and sealing bags, prevented that powder from leaking from the packaging bag valve port; After having packed, do not enter pressurized air and link to each other with atmosphere, this moment, rubber ring shrank, and packaging bag can be taken off from feed nozzle.
Dust collecting is made up of dust removing tube 14 and dust excluding hood 10, dust removing tube and dust excluding hood all are connected to air extracting pump, mounted valve 15 on the dust removing tube 14, dust removing tube be positioned at the bottom of vacuum packing chamber and stretch into vacuum-packed indoor, dust excluding hood 10 be positioned at the vacuum packing chamber top directly over.In packaging process, dust removing tube valve 15 is closed, and after stopping charging, dust removing tube valve 15 is opened, and the dust of vacuum packing chamber the inside is extracted.The dust excluding hood at top is to be used for removing the dust that waves when vacuum packing chamber's door is opened, to prevent the pollution of dust to the workshop.The powder that dust collecting is extracted out can be reclaimed, avoid waste.
Feeding device is made of feed pipe 4 and feed bin 5, feed bin 5 is fixed on the support 9, one-level inlet valve 6 and secondary inlet valve 7 and nozzle purge valve 8 are installed on the feed pipe 4, and one-level inlet valve 6 and secondary inlet valve 7 all are the dish valve, and nozzle purge valve 8 is connected with pressurized air.When beginning to pack, two inlet valves are opened, and the nozzle purge valve is closed, package weight reach setting near target weight the time, close the one-level inlet valve, feed rate reduces, and carries out accurate charging; When package weight reaches target weight, close the secondary inlet valve and stop charging, the nozzle purge valve is opened 0.1-0.5 second then, and pressurized air blows into the product that remains in the nozzle in the packaging bag, to guarantee the precision of package weight.Feed pipe 4 is connected with feed nozzle 25 through rubber bush 16, and the vibrations of feed bin are passed to vacuum packing chamber and influenced weighting apparatus when being used to prevent wrapping machine work.
Weighting apparatus can be that the elastic force that has scale claims, vacuum packing chamber hangs on the bracing frame 9 by check rod, constitutes " pan of a steelyard " of weighting apparatus, claims the weight that shows to come the manual opening-closing inlet valve according to elastic force; Weighting apparatus also can be made up of load transducer 11 and control circuit, and load transducer is fixed on the bracing frame, and the weight of induction is transferred to control circuit, and the output signal of control circuit is used to control the keying of one-level inlet valve and secondary inlet valve; Package weight in all right display packing machine working process of control circuit, average feed rate etc. realize the automatic monitoring of packaging process.
The employed packaging bag of vacuum packing machine is multiwall kraft or stretchable paper valve port bag, and the packaging bag interlayer can be for crossing film punching or non-film punching or the non-porous structure of crossing, and innermost layer is a non-porous structure.Cross the film perforation structure and make packaging bag have certain permeability to air, certain moisture resistance is arranged again simultaneously.Because packaging bag has permeability to air, the interior gas of packaging bag can be drawn out of and prevent that product is drawn out of, and the packing of product is closely knit, is very suitable for the packing of powder.
