Abstract

PURPOSE:To enhance workability in the filling of a caulking agent to a large extent, by integrally forming the engaging part to a work groove surface part and the leveling surface of the caulking agent to the lower part of an emitting nozzle main body. CONSTITUTION:The nozzle main body 2 of the emitting nozzle 5 connected to the supply apparatus of a caulking agent C is formed into an almost rectangular parallelepiped shape and an emitting orifice 1 is provided to the nozzle main body 2 so as to pierce therethrough. Each of both lower side surface of the nozzle main bodies 2 is formed into a taper surface 6 of which the width becomes narrower toward the lower end side thereof and the engaging part 3 capable of being engaged with the surface part of the grove (d) provided to a work (a) is formed. Further, the lower surface of the engaging part 3 is formed into a flat leveling surface 4. In working, the engaging part 3 provided to the lower end part of the emitting nozzle 5 is engaged with the groove (d) of the work (a) and, if the emitting nozzle 5 is run while the caulking agent C is emitted and leveled by a leveling surface 4, finishing and filling can be performed without loozing of the caulking agent C from the groove (d).

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a discharge nozzle for filling caulking agent into grooves such as joint grooves, and more specifically, to greatly improve the workability of filling caulking agent into grooves. related to technology.

[Background technology] When filling a groove such as a grout with caulking agent, masking tape is pasted on both sides of the groove to prevent masking, and after filling the groove with caulking agent, The surface of the caulking agent is leveled with a leveler, the excess caulking agent is scraped off, and the masking tape is then removed.In this way, filling the grooves with caulking agent is complicated and there is a lot of material loss. There was a problem that occurred.

[Object of the Invention] The present invention has been made in view of these problems, and its purpose is to rationally configure the discharge nozzle so as to eliminate the need for masking work.
To provide a structure of a caulking agent discharge nozzle capable of filling grooves of a workpiece with the caulking agent while simultaneously performing surface finishing without protruding or causing material loss.

[Disclosure of the Invention] The present invention includes forming a fitting part 3 that fits into the groove surface of a workpiece a in the lower part of a nozzle body 2 having a discharge hole 1 therethrough, and a caulking agent discharged onto the lower surface of the fitting part 3. This relates to the structure of a caulking agent discharge nozzle formed by forming a leveling surface 4 for leveling the surface of C. By configuring it in this way, it has been possible to achieve the objective ``-2''. In other words, when the fitting part 3 is inserted into the groove light part and the caulking agent C is discharged, the masking work is performed by pressing the caulking agent C with the leveling surface 4 on the lower surface and discharging it while leveling it. The caulking agent C can be filled without causing the caulking agent C to protrude from the groove d and without causing material loss.

Embodiments of the present invention will be described in detail below based on the drawings.

A nozzle body 2 of a discharge nozzle 5 to which a supply device (not shown) for supplying caulking agent C is connected is formed into a substantially rectangular parallelepiped shape, and a discharge hole 1 is formed through the nozzle body 2. Both sides of the lower part of the nozzle body 2 are tapered surfaces 6 whose width becomes narrower toward the lower end, and a fitting part 3 is formed at the lower end of the nozzle body 2 to be able to fit into the surface of the groove d of the workpiece a. be.

Second, the lower surface of the front part 3 is formed into a flat leveled surface 1. According to this kind of 4()I friend 1, the 21st n1(2;
); [As above, the fitting part 3 at the lower end of the discharge nozzle 5 is fitted into the surface of the groove d of the workpiece a, and the caulking agent C is leveled by discharging the caulking agent (4). The discharge nozzle 5 is moved in 77 rows while pressing and leveling the caulking agent C. Since filling is performed while pressing the caulking agent C in this way, the caulking agent C does not protrude from the groove, and the caulking agent C is filled while finishing. It is something that can be filled.

In such a case, as shown in tjS3 to tpJ5,
The inclination angle θ of the groove d of the workpiece a and the insertion part 3 of the nozzle body 2
If the angle θ' of the tapered surface 6 is made substantially equal, the pressing effect of the leveling surface 4 will be high, and the protrusion of the caulking agent C can be more reliably suppressed. or,
As shown in FIGS. 6 to 8, by forming a chamfered circular arc surface 7 on the entire surface of the flat surface 4 of the nozzle body 2 and the tapered surface 6 of the fitting part 3 in the running direction, the workpiece a This can prevent damage to the trench horns 8. Furthermore, as shown in FIG. 9, by setting the angle of the tapered surface 6 to approximately 90° and forming the leveling surface 4 into a downwardly convex arc surface, the surface of the caulking agent C can be finished with a concave surface. It is something that can be done. Also, as shown in tpJ10 and 11,
If the inner peripheral surface of the discharge hole 1 and the leveled surface 4 are treated with fluororesin to form the coating film 9, the caulking agent C will not adhere to the discharge hole 1 and the leveled surface 4.

[Effects of the Invention] In summary, the present invention forms a fitting part that fits into the groove light part of the workpiece in the lower part of the nozzle body, and also forms a leveling surface for leveling the surface of the caulking agent discharged on the lower surface of the fitting part. Therefore, when the insertion part is inserted into the groove light part and the caulking agent is discharged, the caulking agent can be pressed down with the leveler on the lower surface and leveled while being discharged, without having to perform masking work. There is an advantage that the caulking agent can be filled without causing the caulking agent to protrude from the groove and without causing material loss.
