Description

Bag sealing structure of pneumatic conveying system

Technical Field

The utility model relates to a pneumatic conveying technical field especially relates to a pneumatic conveying system sack seal structure.

Background

In the pneumatic conveying system, bag opening and blanking are carried out on bagged materials through a bag opening station, so that the materials in the bags enter a feeding cylinder and enter the pneumatic conveying system. In a common bag opening station, a bag forming material is usually cut, and then the cut is positioned corresponding to a feed port of the bag opening station, and the material falls into the feed port under the action of self gravity. In this operation, the cut of the bag is usually fitted to the inner peripheral surface of the feed inlet. If the blanking process is not smooth or gas backflushing occurs, the outlet (the cut) of the bag is blown up, so that the bag cannot be smoothly attached to the inner circumferential surface of the feed port, the outlet of the bag is not tightly attached to the feed port any more, the outlet is inclined outwards and turned over, and the leakage risk is caused.

Further, in order to stably lift the sealing pressure plate, the lifting device comprises a lifting cylinder and a guide device, the lifting cylinder is fixed on the fixed mounting plate, and the end part of a piston rod of the lifting cylinder is vertically fixed with the sealing pressure plate; the guide device comprises a guide sleeve fixed on the fixed mounting plate and a guide rod connected in the guide sleeve in a sliding manner, and the sliding direction of the guide rod is parallel to the telescopic direction of the piston rod of the lifting cylinder.

Furthermore, the end part of the guide rod corresponding to the vertical fixing side of the piston rod and the sealing pressure plate is also vertically fixed with the sealing pressure plate.

The beneficial effects of the utility model are that, the utility model provides a pneumatic conveyor system sack seal structure, structural design is reasonable, drives the sealed clamp plate oscilaltion through the lift cylinder, realizes the sealed process between filling up and the sealed pad of inner tube of sealed clamp plate and urceolus, but the sack export is followed the crimping and is sealed and sealed clamp plate between the inner tube, can not take place to blow up, outer oblique, turn over and roll over, effectively avoids the risk of revealing at the sack unloading.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the preferred embodiment of the present invention.

In the figure 1, a feeding cylinder 2, a discharging hole 3, a feeding hole 4, a sealing pressure plate 5, an inner cylinder 6, an outer cylinder 7, an inner cylinder sealing gasket 8, an outer cylinder sealing gasket 9, a fixed mounting plate 10, a lifting cylinder 11, a guide sleeve 12, a guide rod 13, a piston rod 14 and a bag.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The bag sealing structure of the pneumatic conveying system shown in fig. 1 is the best embodiment of the present invention, which comprises a feeding cylinder 1, wherein the feeding cylinder 1 has a feeding port 3 at the upper end and a discharging port 2 at the lower end. The feeding cylinder 1 comprises an outer cylinder 6 and an inner cylinder 5 which is sleeved in the outer cylinder 6, and the lower edge of the outlet of the bag is correspondingly placed into the feeding hole 3 of the feeding cylinder 1.

The 1 outer peripheral face of a feeding section of thick bamboo on be fixed with fixed mounting panel 9, the symmetry is equipped with two sets of elevating gear at least on the fixed mounting panel 9, elevating gear end connection has seal clamp plate 4, 6 outer wall upper ends of urceolus be fixed with sealed pad 8 of urceolus, 5 outer wall upper ends of inner tube are fixed with sealed pad 7 of inner tube, terminal surface respectively with sealed pad 8 of urceolus and the sealed 7 end face contact of inner tube under the seal clamp plate 4, along the crimping between sealed pad 7 of seal clamp plate 4 and inner tube under the export of sack.

In order to stably lift the sealing pressure plate 4, the lifting device comprises a lifting cylinder 10 and a guide device, the lifting cylinder 10 is fixed on the fixed mounting plate 9, and the end part of a piston rod 13 of the lifting cylinder 10 is vertically fixed with the sealing pressure plate 4; the guiding device comprises a guiding sleeve 11 fixed on the fixed mounting plate 9 and a guiding rod 12 connected in the guiding sleeve 11 in a sliding manner, and the sliding direction of the guiding rod 12 is parallel to the telescopic direction of a piston rod 13 of the lifting cylinder 10. The end of the guide rod 12 corresponding to the side where the piston rod 13 is vertically fixed to the sealing pressure plate 4 is also vertically fixed to the sealing pressure plate 4.

The bag sealing structure of the pneumatic conveying system is reasonable in structural design. The lifting cylinder 10 drives the sealing pressure plate 4 to move up and down, so that the sealing process between the sealing pressure plate 4 and the outer cylinder sealing gasket 8 and the inner cylinder sealing gasket 7 is realized. When the lifting cylinder 10 pushes the sealing pressing plate 4 to ascend, the lower edge of the outlet of the bag is sleeved outside the inner barrel sealing gasket 7, then the lifting cylinder 10 drives the sealing pressing plate 4 to press downwards, the lower end face of the sealing pushing plate is pressed on the outer barrel sealing gasket 8 and the inner barrel sealing gasket 7, the lower edge of the outlet of the bag is pressed between the inner barrel 5 and the sealing pressing plate 4, the lower edge of the outlet is located between the outer barrel 6 and the inner barrel 5, and blowing, outward inclining and turning over cannot occur. The material in the bag falls, can directly fall downwards from the inner cylinder 5 along the bag until the material is discharged from the discharge port 2, and can not fall back from the space between the bag outlet and the wall of the feeding cylinder 1, so that the leakage risk at the bag outlet is avoided.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
