Abstract
The utility model discloses a feeding pressurization device. The feeding pressurization device comprises a primary pneumatic device formed by a main piston gas cylinder and a glue barrel; a secondary pressurization device is arranged on one side of the primary pneumatic device and comprises a gas cylinder; a piston rod is arranged in the gas cylinder; a piston rod platen is arranged at the top of the piston rod in a matching manner and extends into a pressurization chamber; a feeding port and a discharge port are conductively formed in the pressurization chamber; a one-way valve is arranged on a channel for the feeding port and the pressurization chamber, and glue only can flow into the pressurization chamber via the feeding port under the restraint of the one-way valve. Owing to the additionally added secondary pressurization device, the feeding pressurization device solves the existing problem that the glue can not be extruded under lower atmospheric pressure, and is improved in working stability and product qualification rate.
Description
Technical field
The utility model relates to a kind of glue injection equipment instrument field, is specifically related to a kind of supercharging device of the feed for glue injection equipment.
Background technology
In existing industrial production, often need to use glue filling device, by some gluey fluid injectings in working surface or gap that some are tiny, also have some traditional dual liquid type glue-injection machines, can make glue to solidify rapidly by injecting after glue and curing agent mixing in the process of work, play insulation, heat radiation or other physics and be used as, this class glue-injection machine is multiplex in the fields such as automotive electronics, low-voltage electrical, for example, with for the manufacture of encapsulated transformer.
In glue filling device, the glue feeding machanism is supplied glue to glue filling device at present, and by pressure mechanism, piston push rod, send glue into glue injection units, electromagnetic valve switch, and step motor control, metering is carried, and guarantees successively carrying out of injecting glue work.The feeding machanism generally used now is to use the cylinder pressure feed by packing element, and cylinder to external pressure, is delivered to glue injecting head to the glue of packing element.In use there is a larger deficiency in this structure: when the device air pressure inside is lower, when glue viscosity is higher, whole device just can't outwards extrude glue, thereby causes the carrying out that injecting glue work can't be good, has reduced the qualification rate of product.
Summary of the invention
The utility model purpose is to provide a kind of feed supercharging device, by the improvement to structure, has solved the low problem that can't extrude glue of air pressure in the past, has improved the job stability of device and the qualification rate of product.
The technical solution of the utility model is: a kind of feed supercharging device, comprise the pneumatic shuttle formed by main piston cylinder and glue barrel, a described pneumatic shuttle side is provided with the secondary booster device, described secondary booster device comprises a cylinder, be provided with piston rod in described cylinder, the top of described piston rod is equipped with the piston rod platen, described piston rod platen extend into a pumping chamber, with the conducting of described pumping chamber be provided with charging aperture and discharging opening, the path of described charging aperture and pumping chamber is provided with check valve, described check valve restriction glue only can flow in pumping chamber from charging aperture.
Preferably, the piston rod of the described cylinder outside is connected with inlet nozzle.
Preferably, coordinate and be provided with sealing ring with described check valve.
Preferably, the bore of described cylinder is greater than the bore of described main piston cylinder.
The utility model has the advantages that:
1. the utility model is by setting up the secondary booster device at a pneumatic shuttle side, when the device air pressure inside hour, glue is conveyed in supercharging device, through the secondary booster device, drive, and then extrusion glue, solved and installed internal pressure hour in the past, the problem that glue can't extrude, thereby improved the job stability of device, and improved the qualification rate of injecting glue product;
2. the utility model apparatus structure is simple, takes up room little, and noise is also less, and long service life is applicable to promoting the use of.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
The structural representation that Fig. 1 is the utility model embodiment mono-;
The schematic perspective view that Fig. 2 is the utility model embodiment mono-;
The structural representation that Fig. 3 is secondary booster device in the utility model embodiment mono-.
Wherein: 1, main piston cylinder; 2, glue barrel; 3, cylinder; 4, piston rod platen; 5, check valve; 6, charging aperture; 7, discharging opening; 8, inlet nozzle; 9, sealing ring; 10, pumping chamber.
The specific embodiment
Embodiment: referring to shown in Fig. 1 to Fig. 3, a kind of feed supercharging device, comprise the pneumatic shuttle formed by main piston cylinder 1 and glue barrel 2, a described pneumatic shuttle side is provided with the secondary booster device, described secondary booster device comprises a cylinder 3, be provided with piston rod in described cylinder, the top of described piston rod is equipped with piston rod platen 4, described piston rod platen 4 extend into a pumping chamber 10, with 10 conductings of described pumping chamber be provided with charging aperture 6 and discharging opening 7, described charging aperture 6 is provided with check valve 5 with the path of pumping chamber 10, described check valve 5 restriction glue only can flow in pumping chamber 10 from charging aperture 6, coordinate and be provided with sealing ring 9 with described check valve 5.The piston rod outside of described cylinder 3 is connected with inlet nozzle 8, for giving described piston rod, adds lubricating oil.The bore of described cylinder 3 is greater than the bore of described main piston cylinder 1, and the pressure of injecting glue can increase like this, reaches the function of secondary booster.
In use, glue feeding device is supplied glue to glue filling device to device, and by a pneumatic shuttle, piston push rod, send into glue injection units, electromagnetic valve switch, and step motor control, metering is carried, and guarantees the successive of injecting glue work.When pneumatic shuttle hour, by glue being sent in the secondary booster device, check valve is prevented backflow, by bigbore cylinder, carries out piston actuated, glue is transferred out, thereby complete injecting glue work.
Device is in concrete the use time, when air pressure is 5kgf/cm2, cylinder bore is 2cm, the power of theoretical output is 7.85kgf, be more than or equal to 7.85kgf when glue at the resistance of glue injecting head, can't effectively carry glue, and increase external secondary booster device, just can solve an original too small problem of pneumatic shuttle piston motive force.
Above-described embodiment is only explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
