Description
Technical Field
The utility model relates to the field of powder filling, in particular to a vacuumizing device of a valve bag packaging machine.
Background
The valve bag packaging machine is modern packaging equipment suitable for powder and particles, the packaging efficiency is high, and the accuracy also meets the current industrial requirements. However, with the improvement of the industrial standard, higher requirements are provided for the fineness and the specific gravity of the powder, most of the previous powder with the size of about 10 microns can meet the industrial requirements, and in recent years, a plurality of powder with the size of less than 10 microns are emerged in the market, so that the fineness is higher, the activity of the powder is higher, and the fluidity is relatively increased, which provides higher requirements for the packaging machine industry.
Present current packagine machine uses screw rod or air to give as security mode realization packing such as send, but the higher powder of current fineness uses this kind of packagine machine packing difficulty, the reason is that most superfine powder is because the fineness is high, and there is a small part air to exist between the powder, the material is carried to the wrapping bag along with the air is extrudeed in the time of the packing, cause to get into between the material in the wrapping bag density less, initial packing speed can reach high speed high efficiency completely, increase along with material loading, the condition that the material can't get into the wrapping bag will appear when more and more near apart from the sack, just need extrude the interior powder of bag through patting repeatedly and shaking the wrapping bag, with realize continuing the filling behind the compression material volume, whole process must have artifical intervention, greatly reduced production efficiency.

Based on the above, the second material exhaust mechanism comprises a negative pressure fan and a screen, a cavity is arranged in the side wall of the packaging hopper, an air outlet communicated with the cavity is arranged on the packaging hopper, and the air outlet is communicated with the negative pressure fan; the side wall of the cavity close to the discharge port is communicated with the interior of the packaging hopper, and the screen is arranged at the communication position.
Based on the above, the packaging hopper is also provided with an air inlet corresponding to the cavity, and the air inlet is provided with a pressure regulating valve.
On the basis, first material exhaust mechanism includes the spiral auger of motor and tapered, the packing hopper corresponds for the tapered, the spiral auger is rotatory to be set up in the packing hopper, motor drive connects the spiral auger.
Compared with the prior art, the utility model has substantive characteristics and progress, and particularly, the utility model eliminates the air in the materials before the materials are filled through the mutual matching of the first material exhaust mechanism and the second material exhaust mechanism, so that the air among the materials entering the packaging bag is extremely little, the manual bag squeezing and exhaust are not needed, and the utility model has the advantages of simple structure, time saving, labor saving and convenient use.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Description of reference numerals: 1. a packing hopper; 2. a feed inlet; 3. a discharge port; 4. a motor; 5. a spiral auger; 6. a cavity; 7. an air inlet; 8. a pressure regulating valve; 9. an air outlet; 10. and (4) screening.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the vacuumizing device of the valve bag packing machine comprises a packing hopper 1, wherein a feeding hole 2 is formed in the top of the packing hopper 1, and a discharging hole 3 is formed in the bottom of the packing hopper 1; the packaging hopper 1 is internally provided with a first material exhaust mechanism and a second material exhaust mechanism respectively, and the second material exhaust mechanism is arranged corresponding to the tail end of the first material exhaust mechanism.
When the material discharging device is used, materials enter the packaging hopper 1 from the feeding hole 2, air in the materials is discharged through the first material exhaust mechanism, and then the air in the materials is discharged through the second material exhaust mechanism, and then the materials are discharged through the discharging hole 3. In reality, the discharge port 3 is used for butting the valve bag.
Specifically, first material exhaust mechanism includes motor 4 and the spiral auger 5 of tapered, packing hopper 1 corresponds for the tapered, spiral auger 5 is rotatory to be set up in the packing hopper 1, motor 4 drive connection spiral auger 5. Because the packing hopper 1 and the spiral auger 5 are conical, the space in the hopper from the feeding port 2 to the discharging port 3 is gradually reduced, and the spiral auger 5 extrudes the material while conveying the material, so that air is discharged out of the material.
The second material exhaust mechanism comprises a negative pressure fan and a screen 10, a cavity 6 is arranged in the side wall of the packaging hopper 1, an air outlet 9 communicated with the cavity 6 is formed in the packaging hopper 1, and the air outlet 9 is communicated with the negative pressure fan; the side wall of the cavity 6 close to the discharge hole 3 is communicated with the interior of the packaging hopper 1, and the communicated part is provided with the screen 10. The negative pressure fan performs negative pressure pumping operation in the cavity 6, sucks air discharged by materials extruded by the spiral auger 5, and simultaneously performs further negative pressure degassing treatment on the extruded materials by negative pressure. Preferably, the packaging hopper 1 is further provided with an air inlet 7 corresponding to the cavity 6, and a pressure regulating valve 8 is arranged at the air inlet 7. In the embodiment, the screen 10 adopts a needle felt filter cloth, the air holes are about 5-7 microns, trace powder can permeate out in the practical use, and the later process adopts a dust remover to filter the exhausted air.
The pressure regulating valve 8 is in a closed state when the air pressure range is preset, the negative pressure fan performs negative pressure pumping treatment on the cavity 6, when the negative pressure in the cavity 6 exceeds the preset value, the pressure regulating valve 8 is automatically opened, outside air enters the cavity 6, and the pressure regulating valve 8 is automatically closed after the preset pressure is reached.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
