Abstract
This patent discloses a kind of automatic bag feeding asepwirator pump, realize twice adsorption operations in automatic bag feeding technique with an equipment.Comprise cylinder body, the first chamber and the second chamber is provided with in cylinder body, first chamber and the second chamber are connected outside cylinder body respectively by the first aspirating hole and the second aspirating hole, piston cylinder runs through the first chamber and the second chamber is slidably connected in cylinder body, the first piston and the piston rod that are arranged in the first chamber are affixed, the second piston and the piston rod that are arranged in the second chamber are slidably connected, piston rod is provided with boss, during piston rod first half forced stroke, during boss and the second piston forced stroke later half from, piston rod, boss promotes the second piston and to bleed acting.Piston rod in this device once promotes to realize the first aspirating hole and the second aspirating hole successively implements pumping action, can meet the needs of automatic bag feeding twice absorption of wrapping machine.
Description
Technical field
The utility model relates to a kind of asepwirator pump.
Background technology
Packaging industry generally claims 25kg-50kg material package to attach most importance to bag packaging, and state's packing inside bag mostly is uncovered woven bag, kraft paper bag, PP/PE bag etc., and the equipment realizing its automatic packaging is attached most importance to bag package machine.In heavy bag package machine, automatic bag feeding machinery hand is the functional mechanism of its indispensability, and the upper bag mode of automatic bag feeding machinery hand directly affects packing timber, upper bag fiduciary level and package speed; Packaging bag is delivered to out a bag discharge station by the upper bag mode of a current automatic bag feeding machinery hand mainly vacuum suction, and second adsorption opens the package sack; Packing timber is coated knitted bag, craft paper, PP/PE bag.
Have at present a kind of automatic bag feeding machinery of wrapping machine on hand bag mode be: one time packaging bag is delivered to out a bag discharge station by vacuum suction, and second adsorption opens the package sack blanking.To packing timber, the efficiency of packaging facilities is had higher requirement.Due to the absorption of needs secondary vacuum, usually need multiple vacuum pump cooperating to realize second adsorption, improve cost and the complexity of equipment.
Utility model content
The utility model is intended to provide a kind of automatic bag feeding asepwirator pump, realizes twice adsorption operations in automatic bag feeding technique with an equipment.
Automatic bag feeding asepwirator pump in this programme, comprise cylinder body, the first chamber and the second chamber is provided with in cylinder body, first chamber and the second chamber are connected outside cylinder body respectively by the first aspirating hole and the second aspirating hole, piston cylinder runs through the first chamber and the second chamber is slidably connected in cylinder body, the first piston and the piston rod that are arranged in the first chamber are affixed, the second piston and the piston rod that are arranged in the second chamber are slidably connected, piston rod is provided with boss, during piston rod first half forced stroke boss and the second piston from, during piston rod later half forced stroke, boss promotes the second piston and to bleed acting.
The working process of this device can be divided into front and back two halves forced stroke, and when first half forced stroke, the first aspirating hole is bled acting, and when later half forced stroke, the second aspirating hole starts acting of bleeding.Specifically, to advance roughly general distance at first half forced stroke piston rod, it drives affixed first piston to vacuumize in the first chamber, and device starts front boss and the second piston maintains certain distance, and when first half forced stroke, boss is gradually near the second piston.Represent later half forced stroke to start when boss touches the second piston, in this process, boss promotes the second piston and vacuumizes in the second chamber, and now first piston still can continue to bleed.Generally speaking, the piston rod in this device once promotes to realize the first aspirating hole and the second aspirating hole successively implements pumping action, can meet the needs of automatic bag feeding twice absorption of wrapping machine.
Further, bottom the piston position of the first chamber and the second chamber, air extractor vent is provided with.The resistance of gas to piston-advance can be reduced.
Further, spring coil is provided with between the second piston and the second cavity bottom.Spring coil can help the second piston to reset after the work of bleeding completes.
Further, the second piston and piston rod splined.Processing maintenance is more convenient.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the utility model embodiment.
Fig. 2 is the schematic diagram that the second aspirating hole of the utility model embodiment is about to when starting working.(boss starts to promote the second piston)
Fig. 3 is the schematic diagram of the utility model embodiment forced stroke when completing.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: cylinder body 1, first chamber 2, first aspirating hole 21, first air extractor vent 22, first piston 23, second chamber 3, second aspirating hole 31, second air extractor vent 32, second piston 33, piston rod 4, boss 5, slide opening 6, spring coil 7.
As shown in Figure 1, 2, 3: in cylinder body 1, be disposed with the first chamber 2 and the second chamber 3 from right to left, piston rod 4 runs through from the central horizontal of cylinder body, simultaneously through the first chamber and the second chamber.Left end (bottom) below being respectively equipped with the first aspirating hole 21 and the second aspirating hole 31, first chamber and the second chamber above the right-hand member of the first chamber and the second chamber is respectively equipped with the first air extractor vent 22 and the second air extractor vent 32.
In the first chamber, piston rod and first piston 23 key connecting, can be vacuumized by the first aspirating hole after piston rod drives first piston to move.
Be provided with the slide opening 6 of accommodating boss 5 in the right of the second chamber, boss fixes on the piston rod.By splined on the piston rod, the second piston and piston rod can axial relative movements, and be provided with spring coil 7 in the second chamber, the two ends of spring coil are connected in the bottom of the second chamber and the left side of the second piston respectively for the second piston 33 in second chamber.Start to promote the second piston at piston rod one end stroke rear boss that advances, thus the second piston is moved in the second chamber, and vacuumized by the second aspirating hole.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
