Description

Technical Field

[0001] This application belongs to the field of glue application machine devices, and specifically relates to a fixing structure for a glue application gun. Background Technology

[0002] When two components need to be connected, welding, riveting, and bonding are commonly used. For example, some components in passenger cars are often connected by bonding inner and outer panels due to functional and styling requirements. The adhesive used is a composite adhesive composed of A and B adhesives. Since the A and B adhesives only have adhesive properties after mixing and both A and B adhesives have good fluidity before mixing, the adhesive often hardens due to the long pause in dispensing during the mixing section. Therefore, a disassembled glue gun needs to be connected to one of the three-way connectors of the glue hose connector that connects to the A and B glue hoses. The glue gun contains a spiral core to stir and mix the A and B adhesives evenly. The glue gun can be set with a suitable glue outlet diameter, and it can be replaced in time if glue gun blockage occurs, avoiding production delays. The glue gun and the glue hose connector are usually connected by a pipe thread. The operation of installing and disassembling the glue gun is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a fixing structure for a glue applicator gun, which facilitates the quick replacement of the glue applicator gun and reliably fixes the connection and separation of the glue applicator gun and the glue hose connector.

[0004] To achieve the above objectives, this application provides the following technical solution: a fixing structure for a glue-applying gun, comprising a tapered cylindrical shape with a smaller upper end and a larger lower end on the outer wall of the glue inlet end of the gun body, or a flared hole with a larger upper end and a smaller lower end on the inner wall of the nozzle. The gun body has a variable diameter section on its tube body, and a U-shaped notch is located at the edge of a flat support plate. The U-shaped notch and the variable diameter section of the gun body form a sliding displacement along the direction of the U-shaped notch and a limiting fit along the length direction of the gun body. The support plate is connected to a lifting mechanism.

[0005] The above technical solution achieves the following effect: the conical outer wall or flared inner wall of the glue inlet end of the gun body connects to the end of the glue outlet connecting tube of the glue hose connector. This socket-fitting conical surface interaction effectively solves the sealing connection while improving connection efficiency. The U-shaped notch of the support plate, in conjunction with the diameter-changing part of the gun body, restricts the free displacement of the gun body relative to the support plate in the length direction. When the support plate moves, it drives the gun body to move, achieving mutual socketing and separation with the end of the glue outlet connecting tube. This improves the assembly and disassembly efficiency of the gun body and the glue outlet connecting tube, while ensuring the sealing stability of the assembled state of the gun body and the glue outlet connecting tube.

[0011] like Figure 1-7 As shown, a fixing structure for a glue-applying gun includes a glue inlet end of the gun body 10 with an outer wall that is conical with a smaller upper part and a larger lower part, or an inner wall that is flared with a larger upper part and a smaller lower part. The gun body 10 has a variable diameter section on its tube. A flat support plate 20 has a U-shaped notch 21 at its edge. The U-shaped notch 21 and the variable diameter section of the gun body 10 form a sliding displacement along the direction of the U-shaped notch 21 and a limiting fit along the length of the gun body 10. The support plate 20 is connected to a lifting mechanism.

[0012] In the above technical solution, there are two ways to connect the outer wall of the glue inlet end of the tube gun body 10 to the glue tube connector.

[0013] Reference Figure 5 As shown, in one embodiment, the outer wall of the glue inlet end of the glue gun body 10 is a conical shape with a smaller upper part and a larger lower part, and the inner edge of the glue outlet connection port of the glue tube A of the glue tube connector is a conical shape with a smaller lower part and a larger upper part. When the glue gun is connected to the glue tube connector, the outer wall of the glue inlet end of the glue gun body 10 fits against the inner wall of the glue outlet connection port of the glue tube A of the glue tube connector, which is simple to match, thereby reducing disassembly and assembly time and improving production efficiency.

[0014] Reference Figure 6 As shown, another embodiment is that the inner wall of the glue inlet end of the glue gun body 10 is a flared hole with a larger upper part and a smaller lower part. When the glue gun is connected to the glue tube connector, the inner wall of the glue inlet end of the glue gun body 10 fits against the outer wall of the glue outlet of the glue tube A of the glue tube connector. This embodiment is simple to use and avoids the glue from seeping into the body of the glue gun body 10.

[0015] In the above scheme, the glue inlet end of the tube gun body 10 and the glue outlet of the glue tube A of the glue tube connector are connected by a tapered surface, which is quick and reliable.

[0016] The U-shaped notch 21 at the edge of the support plate 20, together with the variable diameter section of the gun body 10, provides a limiting fit along the length of the gun body 10, thus supporting it. Simultaneously, the U-shaped notch 21 allows the variable diameter section of the gun body 10 to slide along its opening, facilitating the assembly and disassembly of the glue applicator. Since the U-shaped notch naturally positions the glue inlet of the gun body 10 against the connection port of the glue hose connector, and the support plate 20 is connected to a lifting mechanism, the connection and separation of the glue inlet of the gun body 10 from the glue hose connector is naturally achieved as the lifting mechanism moves.

[0017] The connection and separation of the fixed tube gun body 10 and the hose connector can be achieved in two ways.

[0018] One implementation method is as follows Figure 1 , 7 As shown, the U-shaped notch 21 has a groove 211 on its wall surface, and a protrusion 11a is provided on the upper middle section of the barrel body 10, which is fitted into the groove 211.

[0019] At this time, the upper surface of the support plate 20 supports the lower surface of the protrusion 11a. The slot 211 cooperates with the protrusion 11a to restrict the displacement of the tube gun body 10 in the length direction. When the glue gun is separated from the glue tube connector, the slot 211 blocks the upper surface of the protrusion 11a, thereby driving the tube gun body 10 to move to avoid the tube gun body 10 sticking to the glue tube connector, thus saving the amount of manual operation.

[0020] Another implementation method is as follows Figure 2 As shown, a groove 11b is provided on the upper middle section of the barrel of the gun body 10, which is engaged at the edge of the U-shaped notch 21 of the support plate 20.

[0021] The groove 11b and the U-shaped notch 21 provided on the upper middle section of the tube body 10 of the tube gun body support the tube gun body 10. The groove 11b restricts the displacement of the tube gun body 10 in the length direction, so that when the glue application tube gun is separated from the glue tube connector, the tube gun body 10 is moved to avoid it sticking to the glue tube connector.

[0022] Preferred, such as Figure 1 As shown, the protrusion 11a is an annular ring circumferentially placed around the barrel body 10 of the gun body.

[0023] The annular protrusion 11a provides uniform support to the tube gun body 10, and the smooth contour of the annular ring also facilitates the sliding of the protrusion 11a in the slot 211, making it easy to assemble and disassemble the glue application tube gun.

[0024] Preferred, such as Figure 2 As shown, the groove 11b is an annular groove that is circumferentially placed around the barrel of the barrel body 10.

[0025] The upper and lower openings of the annular groove 11b slide in conjunction with the upper and lower surfaces of the opening wall of the U-shaped notch 21, and are similar to the setting of the annular protrusion 11a. The annular groove shape facilitates the engagement and sliding of the groove 11b with the U-shaped notch 21, making it easy to replace the glue applicator gun.

[0026] like Figure 3 , 4 As shown, the lifting mechanism connected to the pallet 20 is a cylinder 30. The lower end of the piston rod 31 of the cylinder 30 is connected to the pallet 20 body on the side of the U-shaped notch 21. There are two cylinders 30 and they are symmetrically placed on the side of the side wall of the U-shaped notch 21. The cylinder body of the cylinder 30 is connected to the frame.

[0027] The support plates 20 on both sides of the U-shaped notch 21 are connected to the lower end of the piston rod of the cylinder 30, thus ensuring that the support plates 20 rise and fall and maintain a horizontal posture during the extension and retraction of the piston rod 31 of the cylinder 30. Since the width of the U-shaped notch 21 is greater than the diameter of the tube gun body 10, it is not necessary to strictly ensure that the tube gun body 10 is concentric with the glue outlet of the glue tube A of the glue tube connector in the initial state. Due to the fit between the conical head and the conical hole, even if there is a small range of concentricity error between the two, when the tube gun body 10 and the glue tube A of the glue tube connector approach each other, the conical mating surface has a guiding effect, that is, the tube gun body 10 has floating displacement in the depth direction and the width direction of the U-shaped notch 21, thereby ensuring the accurate docking of the tube gun body 10 and the glue tube A of the glue tube connector.
