Abstract
The utility model relates to an improved structure of a connection joint for sealing an injecting adhesive valve stem with frequent motion, which comprises a joint axis and a valve stem sleeve. A joint mouth is arranged on the joint axis and a main axis is arranged on the valve stem sleeve. A joint cover is arranged between the joint axis and the valve stem sleeve. A bearing is arranged at the outer side of the joint cover, and the joint axis is fixed on the bearing sleeve. As the bearing is arranged at the outer side of the joint cover and the joint axis is arranged on the bearing sleeve, the joint axis dose not contact with the bearing sleeve. When rotating, friction and wear of the parts are very low, so whole service life of the connection joint is long. As a wear washer and a wear spacing ring with sealing and pressure keeping function are arranged between the joint cover and the joint axis, the divulging and divulging pressure phenomenon can be prevented effectively, and the rotating speed of the rotating device can be improved according to requirements completely. The utility model has the advantages of low cost of whole making, convenient usage, and flexible rotation, and is also suitable for being used as a rotating sealing joint in other situation.
Description
Technical field
The utility model relates to a kind of parts of glue-injection machine, especially relates to a kind of structure improvement of the jointing that the injecting glue valve rod of frequent motion is sealed.
Background technique
Glue-injection machine is in when work, need provide continual in the valve rod of rotation and have the glue of certain pressure, and this just need connect the SEALING FITTING that can do relative movement on valve rod.Patent retrieval is found, someone has applied for the patent (number of patent application: 98229436.0) of " liquid in rotation SEALING FITTING " by name, the overcoat of the turnover of its tool oilhole, draining hole and annular oil groove is contained on the mandrel by bearing, have on the mandrel wear-resisting spacer ring and with the corresponding oilhole of annular oil groove, mandrel is fixedly connected by gland and outer buttons rotation mechanism and is integral, rotate with external agency during work, and overcoat does not change.But this class device is complex structure often, and fabricating cost is higher, uses inconvenience, and component wear is big, and deficiencies such as leakage and pressure release take place easily.
Summary of the invention
The utility model mainly is that to solve the existing in prior technology structure comparatively complicated, rotates very not flexibly, and component wear is bigger, and the technical problem of leakage and pressure release etc. takes place easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise nozzle connecting axis and valve stem casing, be provided with on the nozzle connecting axis and connect mouth, main shaft is set on the valve stem casing, between described nozzle connecting axis and valve stem casing, nozzle connecting cover is set, the arranged outside bearing of described nozzle connecting cover, described nozzle connecting axis is fixed on the bearing housing.
As preferably, described nozzle connecting cover and valve stem casing are fixed into one, constitute a cavity therebetween, and the multiple filtration net is set in cavity, intercept blob of viscose and enter nozzle, guarantee that injecting glue is unimpeded.
As preferably, described nozzle connecting axis and nozzle connecting cover inside are provided with and connect the plastic pipe of leading that mouth links up mutually.
As preferably, between described nozzle connecting axis and the nozzle connecting cover gap is set, and wear-resisting spacer ring is set in the nozzle connecting axis lower end, in the nozzle connecting cover upper end wear washer is set, wear-resisting spacer ring matches with wear washer, and the sealing spacer ring also is set between nozzle connecting axis and bearing.
As preferably, described filter screen is set to two-layer usually, and is fixed on the described valve stem casing by punch holder and die holder.
As preferably, on the valve stem casing below the described filter screen internal projecting ring is set, be connected with main shaft under it, and between is provided with seal washer.
Therefore, the utlity model has simple and reasonable, nozzle connecting cover arranged outside bearing, nozzle connecting axis is arranged on the bearing housing, both non-contacts, and when rotating, it is very little to rub, and component wear is little, and whole service life is long, the wear washer and the wear-resisting spacer ring of sealing and pressurize effect between nozzle connecting cover and nozzle connecting axis, have been provided with, can effectively prevent to reveal the generation with the pressure release phenomenon, can improve the rotating speed of rotating machinery fully as required, integral manufacturing is with low cost, easy to use, rotate characteristics such as flexible.Also go for other occasion and do the usefulness of rotary seal joint.
