Description

Technical Field

[0001] This utility model relates to the field of automotive sealant coating, specifically to a manual glue application gun nozzle. Background Technology

[0002] In the modern automotive painting and adhesive application process, adhesive needs to be applied to areas such as the door frames of the four doors to achieve sealing, bonding, filling gaps, or repairing leaks. Typically, this is done manually using a hand-applied adhesive gun, with nozzles shaped like cones or fans. However, using existing hand-applied adhesive guns can lead to problems such as insufficient filling of the sheet metal, causing air bubbles to form at the adhesive application points after the car body passes through the oven. Additionally, excessive adhesive overflow in some areas can push up the sealant, creating wrinkles on the surface. Utility Model Content

[0038] This utility model provides a manual glue application gun nozzle 100. Please refer to [link / reference]. Figure 1 It includes a connecting section 1 and a glue dispensing nozzle 2. The glue dispensing nozzle 2 is connected to the connecting section 1 in the axial direction. The glue dispensing nozzle 2 is a flat nozzle, and a nozzle step 21 protrudes from one side of the glue dispensing nozzle in the axial direction, and the glue dispensing nozzle 2 protrudes in an arc in the radial direction. The axial direction is the glue dispensing direction of the manual glue dispensing nozzle, and the radial direction is the direction perpendicular to the glue dispensing nozzle.

[0039] The manual glue-applying nozzle of this invention can be used for manual glue application in areas such as the four doors of a car body. Using the manual glue-applying nozzle of this invention can solve the problem of wrinkles easily forming in the glue-applying area, and can also basically solve the problem of glue bubbles easily forming in the glue-applying area, greatly saving the repair time required to repair the appearance defects of the sealant.

[0040] This invention does not specifically limit the connecting section 1, which is connected to a manual glue gun. This invention also does not specifically limit the manual glue gun; any commonly used manual glue gun in the art can be used. Please also refer to... Figure 4 A manual glue application gun may include, for example, a connecting nut 41, a connecting rod 42, a manual glue application nozzle 100, and a positioning rod 43. The connecting nut 41 connects to the glue dispensing device. The connecting rod 42 connects to the connecting nut and is used to apply glue to different vehicle models. The style of the connecting rod can be adjusted according to the vehicle model. The manual glue application nozzle 100 connects to the connecting rod 42. The positioning rod 43 connects to the manual glue application nozzle 100 to control the positioning of the manual glue application gun and ensure stable glue dispensing. In one embodiment, the connecting section 1 of this invention is threadedly connected to the manual glue application gun. For example, the connection between the manual glue application gun and the manual glue application nozzle 100 of this invention has an external thread, and the connecting section 1 has an internal thread, thus achieving a threaded connection between the manual glue application gun and the manual glue application nozzle. However, this invention is not limited to this.

[0041] This invention does not impose any particular limitation on the shape of the connecting section 1, as long as it is compatible with conventional manual glue application guns in the art. In one embodiment, the connecting section 1 of this invention is cylindrical.

[0042] In this invention, the glue nozzle 2 is connected to the connecting section 1 along the axial direction, which is the glue dispensing direction of the manual glue gun nozzle, i.e. Figure 1 The X-axis direction is specified in the model. This invention does not impose any particular limitation on the connection method between the connecting section 1 and the dispensing nozzle 2; it can be a movable connection or a fixed connection, such as integral molding. The dispensing nozzle 2 is a flat nozzle, so the connecting section 1 and the dispensing nozzle 2 can be connected through the transition section 3.

[0043] In this invention, the glue dispensing nozzle 2 is shaped like a platypus, with an arc protruding radially, the radial direction being perpendicular to the nozzle 2. Figure 1 The Z-axis direction is perpendicular to the X-axis direction. In one embodiment, the glue dispensing nozzle 2 of this utility model includes an upper edge 22 and a lower edge 23. The direction perpendicular to the glue dispensing nozzle 2 is the direction perpendicular to the upper edge 22 and the lower edge 23. That is, the glue dispensing nozzle 2 protrudes along the arc direction perpendicular to the upper edge 22 and the lower edge 23. Furthermore, the arc protrudes from the lower edge 23 toward the upper edge 22.

[0044] In one embodiment, the upper edge 22 and the lower edge 23 have the same curvature, thus ensuring that the distance between the upper edge 22 and the lower edge 23 is always the same. In another embodiment, the distance between the upper and lower edges is 2.9-3.1 mm. In yet another embodiment, please refer to... Figure 2 The height h of the arc is 2.5-3.5mm. The height of the arc refers to the distance between the highest and lowest points of the lower edge 23 along the Z-axis.

[0045] In one embodiment, the two sides of the upper edge 22 and the lower edge 23 are connected respectively. For example, one side of the upper edge 22 is connected to one side of the lower edge 23, and the other side of the upper edge 22 is connected to the other side of the lower edge 23. Further, the above connection is a smooth connection. Figure 1 As shown, the Y-axis direction is perpendicular to the X-axis and Z-axis directions. "One side" and "the other side" refer to the two sides of the upper or lower edge along the Y-axis direction.

[0046] In one embodiment, in the axial direction, i.e. along the X-axis, the lower edge 23 protrudes a distance from the upper edge 22, i.e., the size of the lower edge 23 is larger than that of the upper edge 22 in the X-axis direction; in another embodiment, in the axial direction, i.e. along the X-axis, the lower edge 23 and the upper edge 22 have the same size, i.e., when viewed from the Z-axis direction, the lower edge 23 and the upper edge 22 are flush.

[0047] This invention alters the glue dispensing arc by making the glue nozzle protrude radially, thus ensuring a smooth and flat glue surface without bubbles after applying glue to manually applied areas such as the four doors of the car body, especially to the folded edges of the car body.

[0048] In this invention, a nozzle step 21 protrudes axially from one side of the dispensing nozzle 2. Here, "one side" refers to one end of the dispensing nozzle 2 along the Y-axis. In one embodiment, the nozzle step 21 is simultaneously located on the same side of both the upper edge 22 and the lower edge 23, and smoothly connects to that side of the dispensing nozzle 2. In another embodiment, the nozzle step 21 is only located on one side of the lower edge 23, with a smooth transition between the lower edge 23 and the nozzle step 21.

[0049] Please also see Figure 3 Viewed radially (i.e., along the Z-axis), the nozzle step 21 of this invention is rectangular. This rectangle has a width *b* in the axial direction (X-axis) and a length *a* in the Y-axis direction. Therefore, the width *b* is 0.9-1.1 mm, and the length *a* is 3.5-4 mm. In one embodiment, the straight-line distance *c* from one side of the nozzle 2 to the other along the Y-axis is 10-12 mm.

[0050] By setting a step on the nozzle, this utility model allows the nozzle of a manual glue applicator to be a certain distance away from the glue application position when applying glue, thereby preventing foreign objects or welding adhesive from affecting the glue applied and avoiding wrinkles.

[0051] This utility model of a manual glue application nozzle can be applied to manual glue application in areas such as car doors in paint shops, reducing sealant bubbles by at least 80% and solving the problem of sealant wrinkles caused by uneven glue application.

[0052] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the claims of this utility model.
