Abstract
The utility model discloses an ejection type glue gun and belongs to a part of a gluing machine. An existing valve rod type glue gun is complex in structure and easy to damage. The ejection type glue gun comprises a gun body and a gun head. The gun head is fixedly connected with the gun body. A glue outlet hole is disposed inside the gun head. A cavity is disposed inside the gun body. The cavity is communicated with the glue outlet hole. A glue inlet connector is arranged on the gun body. A glue inlet hole of the glue inlet connector is communicated with the cavity. The inner diameter of a section of the glue outlet hole close to an outer orifice gradually becomes smaller from inside to outside so that the section of the glue outlet hole is in a circular truncated cone shape. A plugging head is arranged at the outer orifice of the glue outlet hole. The plugging head is provided with a portion with bigger outer diameters and a portion with smaller outer diameters. The maximum outer diameter of the portion with the bigger outer diameters is bigger than the minimum inner diameter of the glue outlet hole close to the outer orifice so that the plugging head can stay in the glue outlet hole and the portion with the smaller outer diameters extends out of the orifice of the glue outlet hole. Through adoption of the glue outlet hole provided with the outer orifice section with gradually smaller inner diameters and the pressing movable plugging head matched with the glue outlet hole, the ejection type glue gun decreases structural parts and is simple in structure and convenient to use, and moreover the glue outlet hole is not prone to be blocked and damaged.
Description
Technical field
The utility model belongs to the adhesive supplier part apparatus, and especially to make the glue rifle relevant with a kind of top-opening type.
Background technology
Adhesive supplier is a kind of fluid glue to be transported to the equipment that workpiece is subjected to Jiao Chu, is widely used in building trade, automobile making maintenance, Glass Curtain Wall Projects, photovoltaic industry etc., is a kind of high efficiency glue instrument of beating.The glue rifle of beating of existing adhesive supplier mainly is comprised of a rifle body and rifle head, in the rifle head plastic hole is set, be provided with glue chamber and the valve pocket of separation in the rifle body, be communicated with by valve opening between glue chamber and the valve pocket, glue chamber front end arranges the plastic hole and is communicated with the rifle head, glue chamber sidewall connects into cemented joint as glue input source, be provided with the piston type valve rod in the valve pocket, valve rod passes valve opening and faces the plastic hole, insert or extract the plastic hole and realize closing and opening of plastic hole by valve rod, the front-end and back-end of valve pocket sidewall connect respectively a gas-tpe fitting as pressed gas input source, move to realize the valve rod insertion or extract the plastic hole by the pressed gas actuate valve stem, sealing ring sealed valve stem and valve opening hole wall are set in the valve opening.The glue rifle valve rod in beating the glue process of beating like this moves in glue, makes it be stained with glue, and glue easily is solidificated on the valve rod, when moving, valve rod will damage sealing ring, glue easily enters valve pocket, even causes valve rod to move in valve opening, causes beating the glue rifle and scraps.Like this to beat glue rifle structure also relatively complicated, manufacturing cost is relatively high.
The utility model content
The purpose of this utility model is exactly to beat glue rifle complex structure, to hold flimsy defective in order to solve existing valve rod type, provides a kind of simple in structure, easy to use and do not allow flimsy top-opening type to make the glue rifle.
For this reason, the utility model is by the following technical solutions: top-opening type is made the glue rifle, comprise rifle body and rifle head, the rifle head is fixedly connected with the rifle body, be provided with the plastic hole in the rifle head, it is characterized in that, be provided with the cavity for accommodating glue in the described rifle body, cavity is communicated with described plastic hole, be provided with into cemented joint on the rifle body, the glue feeding opening that advances cemented joint is communicated with described cavity, and the plastic hole dwindles from inside to outside gradually near the internal diameter in one section in outer aperture, makes this section plastic hole become truncated cone-shaped, the aperture is provided with block head outside the plastic hole, block head has external diameter major part and external diameter smaller portions, and the maximum outside diameter of external diameter major part is greater than the plastic hole minimum diameter near one section in outer aperture, makes block head stay in the plastic hole and the external diameter smaller portions are stretched out the aperture, plastic hole.
When the utility model uses, make the glue rifle and drive lifting by lowering or hoisting gear, drop to block head and press against when treating dozen glue workpiece when making the glue rifle, block head is headed on the indentation plastic hole, opens the plastic hole, and glue is gone out from the plastic hole, finishes dozen glue; After playing the rising of glue rifle, block head leaves workpiece, stretches out the plastic hole under glue pressure, with the plastic hole shutoff.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described block head external diameter smaller portions external diameter dwindles gradually.
Described block head becomes spheroidal.
Described block head is divided into the upper and lower two parts that are connected as a single entity, and top is divided into cylinder, and the bottom divides external diameter to dwindle gradually from top to bottom.
Described rifle head and the employing of rifle body are threaded fixing.
Be provided with sealing ring between described rifle head and the rifle body connecting portion, prevent that glue from oozing out from connecting portion.
Use the utility model can reach following beneficial effect: the utility model is pressed portable block head by the top of adopting the diminishing plastic hole of section internal diameter, outer aperture and cooperate with it, reduced constitutional detail, make dozen glue rifle simple in structure, easy to use, the plastic hole is not easy to stop up and damages.
