Abstract
The utility model discloses a glue coating gun with a sucking-back function. The glue coating gun comprises a glue coating gun body, a sprayer head and a control valve for controlling a fluid channel of the glue coating gun body to be opened or closed, wherein the control valve comprises a valve seat, a valve core and a control device, and the valve core is in piston type sliding fit with the valve seat and is driven by the control device to slide out of the valve seat along the flowing direction of fluid to open the fluid channel or to slide into the valve seat along the direction opposite to the flowing direction of fluid to close the fluid channel. The glue coating gun with the sucking-back function has the advantages that the valve core is in piston type connection with the valve seat and is arranged at a glue discharging hole of the valve seat, and at the moment of closing the gun, the valve core slides into the valve seat along the direction opposite to the flowing direction of fluid to ensure that glue fluid remained in a glue coating nozzle can be sucked back under a negative pressure function, so that residual glue liquid can be prevented from flowing out of or leaking along the glue coating nozzle, parts are prevented from being polluted, material waste is also prevented, the spraying quality is ensured, and the cost is saved.

The utility model content
In view of this, the purpose of this utility model provide a kind of coating gun with resorption function close the glue that residues in the gluing mouth behind the rifle can retreating with spool by resorption, can prevent that remaining glue from flowing out or water clock along the gluing mouth, avoid polluting part and waste material, guarantee coating quality, save cost.
Coating gun with resorption function of the present utility model comprises coating gun body, shower nozzle and is used to control the control valve of described coating gun bulk fluid passage opening and closing; Described control valve comprises valve seat, spool and control device, and described spool and valve seat are that piston type is slidingly matched and drive the longshore current direction of flow by described control device and skid off and open the fluid passage and oppositely slipping into of longshore current direction of flow closed the fluid passage.
Further, the rear end face of described spool cooperates by inverted cone surface with valve seat;
Further, described valve seat fluid passage front end is provided with chamfering;
Further, described shower nozzle comprises gluing mouth, adapter sleeve and is used for the nut that is fixedly connected on the adapter sleeve front end that described gluing mouth is coaxial; Described adapter sleeve rear end is by being threadedly connected to the coating gun body and compressing valve seat, adapter sleeve endoporus and the coaxial setting in valve seat fluid passage;
Further, described adapter sleeve endoporus is bigger shoulder hole in aperture, rear end and aperture, adapter sleeve endoporus rear end are formed for holding spool and resorption fluid and confession direction of flow adapter sleeve endoporus front end greater than valve core diameter a cavity volume;
Further, described gluing mouth endoporus is consistent with adapter sleeve endoporus aperture.
The beneficial effects of the utility model are: the coating gun with resorption function of the present utility model, spool and valve seat are that piston type is connected and spool is located at the gum outlet of valve seat, close rifle moment spool and oppositely slip into valve seat along what glue flowed to, make the glue that residues in the gluing mouth can be at resorption under the suction function, can prevent that remaining glue from flowing out or water clock along the gluing mouth, avoid polluting part and waste material, guarantee coating quality, save cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, and as shown in the figure: the coating gun with resorption function of present embodiment comprises coating gun body 1, shower nozzle 2 and is used to control the control valve of described coating gun body 1 fluid passage opening and closing; Described control valve comprises valve seat 3, spool 4 and control device 5, described spool 4 and valve seat 3 are that piston type is slidingly matched and drive the longshore current directions of flow by described control device 5 and skid off and open the fluid passage and oppositely slipping into of longshore current direction of flow closed the fluid passage, valve seat 3 is fixed in coating gun body 1 fluid passage, valve seat 3 endoporus form the part of fluid passage, spool 4 is located at valve seat 3 gum outlets, piston type is slidingly matched and refers to that spool 4 and valve seat 3 are slidingly connected and interference fits, make and close rifle moment and in shower nozzle 2, produce negative pressure, can make the glue resorption that residues in shower nozzle 2.
In the present embodiment, the rear end face of described spool 4 and valve seat 3 cooperate by inverted cone surface, make spool 4 slide spacing by valve seat 3, be beneficial to the slip control of spool 4, increase the composition surface of spool 4 and valve seat 3 simultaneously, good seal performance, the easy machine-shaping of inverted cone surface, before in the present embodiment being, after a reverse side of direction of flow is with a side towards direction of flow.
In the present embodiment, described valve seat 3 fluid passage front ends are provided with chamfering, can carry out correcting to spool 4, and spool 4 can slip into valve seat 3 smoothly when making closed control valve.
In the present embodiment, described shower nozzle 2 comprises gluing mouth 21, adapter sleeve 22 and is used for the nut 23 that is fixedly connected on adapter sleeve 22 front ends that described gluing mouth 21 is coaxial; Described adapter sleeve 22 rear ends are by being threadedly connected to coating gun body 1 and compressing valve seat 3, adapter sleeve 22 endoporus and the coaxial setting in valve seat 3 fluid passages, corresponding valve seat 3 places, the fluid passage of coating gun body 1 are stepped, can carry out axial limiting to valve seat 3, after being installed, adapter sleeve 22 can effectively locate valve seat 3 by adapter sleeve 22 and cascaded surface, and removing adapter sleeve 22 can carry out dismounting to spool 4, is convenient to the maintenance and the replacing of spool 4; The length of gluing mouth 21 and dimensional structure can use and need design by reality, flexibly connect by nut 23 with adapter sleeve 22, are convenient to change and cleaning.
