Technical Field
The utility model relates to a device for coating the surface of liquid from an outlet contacted with a workpiece, in particular to a glass cement gun head.
Background
Glass cement is a material for bonding and sealing various kinds of glass with other base materials, and is widely used. The existing tools for coating glass cement comprise a glass cement gun, a glass cement bottle (i.e. a gun barrel) and a glass cement gun head, wherein the glass cement gun head is generally in a conical tube shape and is screwed on a glass cement bottle mouth when in use. When coating, the glass cement gun is used for pushing and pressing the glass cement from the bottle to extrude out of the glass cement gun head, the glass cement forms a linear cement flow to be filled in the gap, and a raised arc-shaped cement ridge is formed at the gap. Because the arc-shaped glue ridges affect the appearance, the glass cement is usually scraped off by a blade after the glass cement is solidified. Therefore, the existing glass cement gun head needs to be added with a construction procedure, and a large amount of glass cement materials are wasted.

Detailed Description
Example 1
Referring to fig. 1-4, the gun head body of the ball type glass cement gun head of the present invention comprises an extension section 1 and a coating nozzle 2, wherein the upper end of the extension section 1 is provided with a screw thread interface, and the outer wall of the lower end is contracted inwards to form a step; the upper head of the coating nozzle 2 is sleeved and fixed on the step of the lower head of the extension section 1 by an adhesive, and the lower head is contracted inwards to form a conical glue outlet 3; the coating nozzle 2 is internally provided with a coating ball 4 and a supporting device from bottom to top in sequence. The outer surface of the upper part of the extending section 1 of the gun head body is vertically and uniformly distributed with strip-shaped bulges 11 which are parallel to each other.
Referring to fig. 1 to 4, the supporting device includes a disc-shaped upper supporting plate 5 and a disc-shaped lower supporting plate 6, each of which has a glue outlet hole 10 at the middle part, wherein three spherical holes are symmetrically formed in the lower supporting plate 6, and each spherical hole is provided with a ball 7; three cylindrical compression springs 8 are arranged between the upper supporting plate 5 and the lower supporting plate 6, the lower head of each cylindrical compression spring 8 is sleeved on the spherical crown of one ball 7, exposed out of the ball 7 on the upper surface of the lower supporting plate 6, and the upper head of each cylindrical compression spring is sleeved on a positioning pin 9 arranged on the upper supporting plate 5; the tension of the cylindrical compression spring 8 is transmitted to the coating ball 4 through the three balls 7, confining it in the glue outlet 3 and exposing the spherical cap of the coating ball 4.
Referring to fig. 5 in combination with fig. 2 to 4, when the glass cement is coated, the glass cement is extruded from the cement bottle by the glass cement gun, and the gap in the gun head body at the upper part of the coating ball 4 is filled up through the extension section 1 and the glue outlet holes 10 on the upper supporting plate 5 and the lower supporting plate 6. When an operator extrudes the coating ball 4 to objects on two sides of the gap, the coating ball 4 compresses the cylindrical compression spring 8 through the ball 7 under the action of the reaction force of the objects on the two sides of the gap, the coating ball 4 moves upwards, the glue outlet 3 is opened, and the glass cement flows out; at this time, the glue gun continues to pressurize and move uniformly along the gap, and the coating ball 4 rolls along the gap to uniformly fill and coat the glue in the gap.
Referring to fig. 9, when the gap is formed by two objects a and B connected in a straight line, since the coating ball 4 rolls along the edges of the two objects a and B, the formed glue line C (shown by a solid line in fig. 9) is recessed without manual scraping.
