Description
Technical field
The utility model belongs to injection point gluing equipment field, particularly relates to a kind of precise pump glue device.
Background technology
In the prior art, the glue amount of point gum machine control, especially during the residue glue quantitative change in the container, the control of required glue amount is difficult for realizing, if with pressure control, then can be subjected to the influence of air feed stability again.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of precise pump glue device, with the problem of the glue amount control that solves point gum machine in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of precise pump glue device is provided, comprise air inlet pipe (5), pressure pot (1), pressure sensor (3), liquid valve (4), electromagnetic proportional valve (6) and drain pipe (2), described air inlet pipe (5) one ends link to each other with air inlet, the other end is connected pressure pot (1) loam cake place, described drain pipe (5) one ends are inserted into pressure pot (1) bottom, described electromagnetic proportional valve (6) is connected on the air inlet pipe (5), described pressure sensor (3) is arranged on the drain pipe (2), and be connected with electromagnetic proportional valve (6) by holding wire, described liquid valve (4) is connected drain pipe (2) exit.
Beneficial effect
The do not originated influence of air pressure change, residue glue quantitative changeization of native system, the utmost point can be adjusted the pressure of outlet automatically in the short time.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of precise pump glue device, comprise air inlet pipe 5, pressure pot 1, pressure sensor 3, liquid valve 4, electromagnetic proportional valve 6 and drain pipe 2, described air inlet pipe 5 one ends link to each other with air inlet, the other end is connected pressure pot 1 loam cake place, described drain pipe 5 one ends are inserted into pressure pot 1 bottom, described electromagnetic proportional valve 6 is connected on the air inlet pipe 5, described pressure sensor 3 is arranged on the drain pipe 2, and be connected with electromagnetic proportional valve 6 by holding wire, described liquid valve 4 is connected drain pipe 2 exits.
Compressed air is by electromagnetic proportional valve 6, gas pressure acts on the liquid surface of pressure pot 1, impel the liquid in the pressure pot 1 to be pressed into drain pipe 2, liquid is flowed through when being arranged on pressure sensor 3 on the drain pipe 2, fluid pressure acts on the sensing head part of pressure sensor 3, and pressure sensor 3 produces voltage signal and feeds back to electromagnetic proportional valve 6; The signal that electromagnetic proportional valve 6 is passed back according to pressure sensor 3 is adjusted its gas outlet pressure constantly, so that the fluid pressure in the drain pipe 2 is in steady state.
Claims (2)
1. precise pump glue device, comprise air inlet pipe (5), pressure pot (1), pressure sensor (3), liquid valve (4), electromagnetic proportional valve (6) and drain pipe (2), it is characterized in that: described air inlet pipe (5) one ends are connected pressure pot (1) loam cake place, described drain pipe (5) one ends are inserted into pressure pot (1) bottom, described electromagnetic proportional valve (6) is connected on the air inlet pipe (5), described pressure sensor (3) is arranged on the drain pipe (2), and be connected with electromagnetic proportional valve (6) by holding wire, described liquid valve (4) is connected drain pipe (2) exit.
