Description
Technical field
The utility model belongs to spining technology field, more particularly, to a kind of glue metering pump.
Background technology
Metering pump be it is a kind of can meet various stringent technological process needs, flow can within the scope of 0-100% nothing
Grade is adjusted, for conveying a kind of liquid (especially corrosive liquids) special positive displacement pump.Metering pump is also referred to as constant displacement pump or proportioning pump.
Metering pump belongs to reciprocating displacement pump, is used for accurate measurement.As modernization industry is towards automation mechanized operation, far distance automatic control
Make the continuous development of this situation, the matching of metering pump is strong, it is particularly evident to adapt to the extensive advantage of medium, so industrially
It finds broad application.
Spinning pump in the prior art is to use gear structure mostly, it includes cover board and sealing as shown in Fig. 1
Seat (60), cover plate includes being sequentially connected outer cover plate (10), intermediate plate (20) and inner cover plate (30) from the bottom to top, in cover board
Driving shaft (40) and driven shaft (50) are installed, driving gear (41) is equipped on driving shaft (40), is set on driven shaft (50)
Have with driving gear (41) intermeshing driven gear (51), when being rotated by gear, gap between tooth and tooth quantifies
Medium (chemical fibre, glue, finish of spinning etc.) is transported to the other side from the side of gear.Wherein driving gear (41) and
Driven gear (51) is located in intermediate plate (20), and wherein inner cover plate, wherein seal receptacle (60) are stretched out in the end of driving shaft (40)
It is sleeved on driving shaft (40) top and is fixed in inner cover plate (30), be equipped in seal receptacle (60) and the junction of driving shaft (40)
Gasket (61), wherein outer cover plate (10) are equipped with inlet and liquid outlet；Existing glue metering pump at runtime, glue by
When inlet is entered in metering pump, can to the lower part of driving shaft, there are one surges, make driving shaft play up and down, cause actively
Axis and abrasion with driving gear connecting key, eventually lead to driving shaft and are disconnected with driving gear, and metering pump is made to stop fortune
Row.And the worn metals ground off fall into glue the pollution for causing glue, it is therefore necessary to be improved.
Invention content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of glue metering pump, it has
It avoids wearing between driving shaft and driving gear connecting key caused by driving shaft play, and then improves entire metering pump and use
The characteristics of service life.
To achieve the goals above, technical solution used by the utility model is：A kind of glue metering pump, including cover board
And seal receptacle, the cover board include being sequentially connected outer cover plate, intermediate plate and inner cover plate from the bottom to top, and master is equipped in the cover board
Moving axis and driven shaft, the driving shaft be equipped with driving gear, the driven shaft be equipped with driving gear it is intermeshing from
Moving gear, the driving gear and driven gear are located in intermediate plate, and inner cover plate is stretched out in the end of the driving shaft, described close
Envelope cover for seat is mounted in driving shaft top and is fixed in inner cover plate, and the junction of the seal receptacle and driving shaft is equipped with gasket, institute
It states outer cover plate and is equipped with inlet and liquid outlet；The seal receptacle is equipped with gland, and the driving shaft is equipped with groove, the pressure
Cavity is equipped between lid and seal receptacle, it is two mutually kisses that adapter sleeve described in the adapter sleeve engaged with groove is equipped in the cavity
The fastener of conjunction is constituted, and the fastener is that arc panel and straight panel are constituted, and the straight panel is equipped with threaded hole.
Further, the cover board height is higher than the height of driven shaft.
Further, the outer cover plate, seal receptacle are connected with gland by bolt.
With the above structure, the utility model is compared to the prior art advantageously：The application is in cavity
The adapter sleeve that uses of groove on cooperation driving shaft is set, prevents the play of driving shaft, driving shaft and driving gear connecting key it
Between abrasion, improve the service life of entire metering pump, cover plate height higher than the height of driven shaft be avoided that in this way from
Moving axis play.
Description of the drawings
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is adapter sleeve and driving shaft connection status schematic diagram.
Specific implementation mode
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment is shown in shown in Fig. 2 to Fig. 3：Gland 70 is equipped on seal receptacle 60 compared with prior art, in driving shaft 40
It is equipped with groove 42, cavity is equipped between gland 70 and seal receptacle 60, the adapter sleeve engaged with groove 42 is equipped in cavity
