Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the technical solution adopted by the utility model is as follows: the utility model provides a dispensing valve for dispensing machine, includes lower valve body 1 and the last valve body 2 of tubbiness structure, goes up valve body 2 and threaded connection between the valve body 1 down, go up one side of valve body 2 and seted up into jiao kou 3, wear to be equipped with the little dispensing tube 4 of the big one end of cavity and one end down in the valve body 1, the big footpath section of dispensing tube 4 is located valve body 2, and valve body 1 is down worn out to the path section of dispensing tube 4, be provided with the adjusting part 5 that can make dispensing tube 4 longitudinal movement down in the valve body 1, the one end that dispensing tube 4 stretches out down valve body 1 is provided with heating jacket 6, and heating jacket 6 can in time heat dispensing tube 4, avoids dispensing tube 4 internal diameter less, the lower stop up point rubber tube 4 of room temperature.
The small diameter section of the dispensing tube 4 extends out of one end thread of the lower valve body 1 or is integrally formed with a dispensing head, a plurality of openings are arranged on one side surface of the large-diameter section facing the lower valve body 1, the dispensing head is hemispherical, a plurality of glue outlets 7 are arranged on the peripheral side surface of the glue dispensing head, concretely, five glue outlets 7 are uniformly arranged along the glue dispensing pipe 4, the outer diameter of the large-diameter section is smaller than the inner diameter of the upper valve body 2, the periphery of the dispensing tube 4 is arranged at a certain distance from the inner wall of the upper valve body 2, so that the flow of the colloid is convenient, a hemispherical dispensing head is adopted, when the valve body contacts with a workpiece, the extrusion to the workpiece is reduced, a sealing gasket 8 is arranged between the upper valve body 2 and the lower valve body 1, a convex block matched with the opening is integrally formed on the sealing gasket 8, when the large diameter section of the dispensing tube 4 contacts with the sealing gasket 8, the glue solution in the upper valve body 2 is further prevented from flowing into the dispensing tube 4.
The adjusting component 5 comprises a groove arranged in the lower valve body 1, a spring 51 and an adjusting block 52 arranged in the groove, the groove is a rectangular groove, the adjusting block 52 is in threaded sleeve connection with the dispensing tube 4, the adjusting block 52 is matched with the groove, the spring 51 is in sleeve connection with the dispensing tube 4, two ends of the spring 51 are in butt connection with the inner wall of the groove and the adjusting block 52, the adjusting block 52 can move longitudinally in the groove, the elastic force of the spring 51 enables the large-diameter section of the dispensing tube 4 to be attached to the sealing gasket 8, when a dispensing head of the dispensing tube 4 is extruded with a workpiece, a gap is generated between the large-diameter section of the dispensing tube 4 and the sealing gasket 8, a convex block on the sealing gasket 8 is separated from an opening, glue liquid in the upper valve body 2 flows into the dispensing tube 4 through the opening and finally flows onto the workpiece through the glue outlet 7, one end of the heating sleeve 6 is clamped on the adjusting block 52, specifically, the heating sleeve 6 is a heating ring and is sleeved on the small-diameter section of, the heating ring heats after being electrified, so that the glue solution in the dispensing tube 4 is heated, the length of the large-diameter section of the dispensing tube 4 is smaller than the height of the inner cavity of the upper valve body 2, and the large-diameter section of the dispensing tube 4 can move in the upper valve body 2 conveniently.
When the dispensing device is used, a dispensing head of the dispensing tube 4 is in contact with a workpiece and extrudes, the acting force of the workpiece on the dispensing tube 4 is greater than the elastic force of the spring 51 on the dispensing tube 4, the large-diameter section of the dispensing tube 4 is far away from the sealing gasket 8, a glue supply device arranged at the glue inlet supplies glue to the dispensing device, the glue solution enters the upper valve body 2 through the glue inlet 3, then enters the dispensing tube 4 through an opening on the large-diameter section, and finally flows into the workpiece from the glue outlet 7 of the dispensing head; after the required glue solution flows out, the dispensing head is far away from the workpiece, and because the acting force of the workpiece on the dispensing head is gradually reduced, the spring 51 extrudes the adjusting plate, the large-diameter section of the dispensing tube 4 is in close contact with the sealing gasket 8, and the glue solution cannot enter the dispensing tube 4, no redundant glue solution is generated on the workpiece, and the precision of glue discharging is effectively ensured.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
