Abstract
The utility model discloses a rubber-cap dropper for adding an adhesive and belongs to the technical field of instruments used in chemical production. The rubber-cap dropper comprises a glass suction tube, an end cover and a rubber airbag; a conical dropper is arranged at the front end of the glass suction tube; the end cover is connected with the terminal end of the glass suction tube by threads, and a circular hole is formed in the centre of the end cover; the rubber airbag is in a semispherical structure, an annular groove is outwards formed at an open end of the rubber airbag, the groove is sleeved in the circular hole of the end cover, and the inner end of the groove is fixed between the glass suction tube and the end cover. The rubber-cap dropper disclosed by the utility model is reasonable in structure and easy to operate, the adhesive can be weighed precisely, and the rubber-cap dropper can be reused.
Description
Technical field
The utility model belongs to the technical field of used utensil in the Chemical Manufacture, especially relates to a kind of glue head dropper that binding agent is used that adds.
Background technology
Often need to use the binding agents such as polyvinyl alcohol, polyvinyl butyral resin in chemical industry and powder metallurgy industry, binding agent can be sticked together loose solid powder or particle, is pressed into the product of required form through mould.All be to adopt bulk container to pour little volume at present in laboratory or industrial production, pour in the vessel that batch mixing uses by little volume again and carry out weighing.Because binding agent is thick liquid state, bring difficulty for the required deal of accurate weighing, in addition, binding agent very easily with the chamber wall adhesion, so that the container that filled has a large amount of glue residue, solidify easily after these residual binding agents are placed, just anchor in the container, cause the significant wastage of raw material and vessel.
Summary of the invention
The glue head dropper that the purpose of this utility model has been to provide a kind of interpolation binding agent rational in infrastructure, practical, simple to operate to use.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: this is a kind of to add the glue head dropper that binding agent is used, mainly formed by glass pipette, end cap and rubber pneumatic bag, wherein, described glass pipette front end is the taper dropper, described end cap is connected with the glass pipette end thread, manhole is set in the middle of the end cap, described rubber pneumatic bag is hemispherical structure, openend outwards arranges annular groove, groove is enclosed within the circular hole of end cap, and the inner end of groove is fastened between glass pipette and the end cap.
As preferably, described glass pipette wall is marked with tag line one, surpasses this tag line when drawing binding agent, in order to avoid binding agent sticks on end cap or the rubber pneumatic bag.
As preferably, described rubber pneumatic bag groove outer diameter R equates with the end cap internal diameter, so that the groove inner end of rubber pneumatic bag can be fastened between glass pipette and the end cap, whole glue head dropper has better air-tightness when guaranteeing the extruding rubber pneumatic bag.
As preferably, described rubber pneumatic bag wall thickness is about 1～4mm.
This is a kind of to add the glue head dropper that binding agent is used, adopt the dropper mode to draw binding agent, can realize accurate weighing, simultaneously, be in sealing state in the whole glue head dropper, can avoid solidifying in the binding agent short time, be convenient to the interior binding agent of glue head dropper and extrude easily, namely can save material and realize the recycling of glue head dropper.
