Description

Technical Field

[0001] The present invention relates to the technical field of glue application tools, in particular to a storage container and a projectile for polyurethane adhesive material. Background Art

[0002] In order to assemble two unconnected items together, in addition to using connectors to fix them, the two can also be bonded together by adhesives. Current gluing tools include glue guns and spray guns, but these tools cannot achieve remote gluing, for example, more than 10 meters, that is, the distance between the gluing operator and the gluing point is more than 10 meters, and remote gluing needs to consider the solidification of the adhesive material. If the adhesive material has been partially or completely solidified before reaching the gluing point, this will reduce the bonding force of the adhesive material, that is, the bonding strength. Therefore, in order to meet the requirements of remote gluing, either the distance between the glue outlet of the gluing tool and the gluing point is shortened, or the components of the adhesive material are mixed and glued at the gluing point. However, existing two-component or multi-component polyurethane adhesives are usually mixed with the components stored separately when gluing, and this storage method is not suitable for remote gluing.

DETAILED DESCRIPTION

[0028] Example 1

[0029] like Figures 1 to 3As shown, the storage container for polyurethane adhesive material in the present invention includes a brittle spacer structure, an agitator 33 and a cylinder with one end sealed. The brittle spacer structure includes a first brittle film layer 36, a second brittle film layer 37 and at least two brittle support layers 38. The brittle support layers 38 are evenly provided with tapered through holes 39 that penetrate the upper and lower surfaces of the brittle support layers 38. The tapered through holes 39 have a depth of 0.4 mm, a diameter of 1.6 mm at the expanded end, and a diameter of 1.6 mm at the expanded end. The diameter of the conical through hole 39 is 1.2 mm, and the distance between the central axes of two adjacent tapered through holes 39 is 2 mm; in the brittle spacer structure, the brittle support layer 38 is arranged between the first brittle film layer 36 and the second brittle film layer 37, and the flared ends of the tapered through holes 39 on different brittle support layers 38 in at least one pair of adjacent brittle support layers 38 are adjacent; the two brittle spacer structures divide the cylinder into a first storage area, a second storage area and a storage area along the axial direction of the cylinder. The material storage area and the agitator assembly area; the lower end of the agitator 33 is arranged in the agitator assembly area, the upper end of the agitator 33 passes through the cylinder cover of the cylinder and is arranged on the outside of the cylinder, and the agitator 33 is rotatably connected to the cylinder cover; when the agitator 33 rotates under the drive of an external force, the lower end of the agitator 33 breaks the brittle spacer structure, and the materials in the first material storage area and the second material storage area are mixed under the drive of the agitator 33; the cylinder is made of a brittle material, and the hole in the cylinder is A linear hole, an angle α between the outer wall of the cylinder and the bottom surface of the cylinder is 98°, the ratio of the wall thickness h1 of the expanded end of the cylinder to the wall thickness h2 of the indented end of the cylinder is 4:1, and the wall thickness h1 of the expanded end of the cylinder is 4 mm. This structure of the cylinder can ensure that the cylinder will not break when it is ejected with a large initial velocity, and when the cylinder hits the target object, the liquid in the cylinder can squeeze the cylinder wall at the end with the thinner wall of the cylinder, thereby realizing impact gluing.

[0030] When the barrel is made of a material that reacts with isocyanate, such as carbomer, a coating should be added to the inner wall of the barrel to prevent the barrel from reacting with the isocyanate when the polyurethane adhesive is stored in a storage container. In this embodiment, the barrel body is preferably made of polycarbonate, and a layer of polystyrene film is added to the inner wall of the barrel body.

[0031] In order to facilitate the transmission connection between the agitator 33 and the output shaft of the stirring drive device, a coupling is provided on the cylinder cover, and the upper end of the agitator 33 is transmission-connected to the coupling.

[0032] The stirring blade mounted on the lower end of the stirrer 33 is a blade with a toothed structure. When the stirrer 33 is rotated by an external force, the toothed structure breaks the brittle spacer structure, and the materials in the first and second storage areas are mixed under the drive of the stirrer 33. The presence of the toothed structure facilitates the blade to break the brittle spacer structure, thereby facilitating uniform mixing of the different components in a relatively short period of time.

[0033] The brittle spacer structure of the polyurethane adhesive storage container 32 in this embodiment ensures that different components stored in the same container are separated. During use, the brittle spacer structure can be broken and the different components can be mixed through stirring, reducing the trouble of injecting different components step by step and also reducing the trouble of measuring the dosage of different components. The cylinder made of brittle material can meet the requirements of remote impact glue application. The cylinder containing the polyurethane adhesive can be used for remote glue application at glue application sites in unknown or hazardous environments, reducing the risk of harm to construction workers due to dangerous factors, such as blocking leaks of toxic gases, fumes, and smoke.

[0035] like Figures 4-6 and Figure 8 As shown, the polyurethane adhesive material projectile includes a material container loading part 30, a launching part 10 and an intermediate part 20, wherein the first end of the material container loading part 30 is detachably connected to the second end of the intermediate part 20, the first end of the intermediate part 20 is detachably connected to the second end of the launching part 10, and the first end of the launching part 10 is detachably connected. A butt 12 is provided on the first end of the launching part 10; the material container loading part 30 is provided with a polyurethane adhesive material filling bin, which is used to load the above-mentioned polyurethane adhesive material storage container 32 storing polyurethane adhesive material; the intermediate part 20 is provided with a stirring motor 22, and when the polyurethane adhesive material storage container 32 is loaded into the polyurethane adhesive material filling bin, the stirring motor 22 is transmission-connected to the stirrer 33 on the polyurethane adhesive material storage container 32; when the launching switch 14 of the launching part 10 is turned, the launching part 10 drives the polyurethane adhesive material storage container 32 to move out of the polyurethane adhesive material filling bin, and the launching switch 14 is provided on the launching handle 11. The launching part 10 is provided with a pneumatic pressurizing device 13, and the pneumatic pressurizing device 13 is fluidically connected to the material container loading part 30 through an air pipeline; when the launching switch 14 of the launching part 10 is turned, the air pipeline between the pneumatic pressurizing device 13 and the material container loading part 30 is connected, and the gas in the pneumatic pressurizing device 13 flows out and drives the polyurethane adhesive material storage container 32 to be moved out of the polyurethane adhesive material filling bin.

[0036] In which, a first clamping structure is provided on the cylinder cover of the polyurethane adhesive material storage container 32, and a second clamping structure 23 is provided on the middle part 20; when the polyurethane adhesive material storage container 32 is loaded into the polyurethane adhesive material filling bin, the first clamping structure is clamped with the second clamping structure 23; when the launch switch 14 of the launch unit 10 is turned and the polyurethane adhesive material storage container 32 is driven by the launch unit 10 to be moved out of the polyurethane adhesive material filling bin, the first clamping structure and the second clamping structure 23 are separated under the action of external force.

The four spring leaves 23-2 are arranged at equal intervals along the circumference of the mounting plate 23-1 and one end of the spring leaf 23-2 is fixedly connected to the mounting plate 23-1. The other end of the spring leaf 23-2 is provided with a clamping protrusion 23-3; when the first clamping structure is clamped with the second clamping structure 23, the clamping protrusion 23-3 is arranged in the clamping groove 34.

[0038] The middle portion 20 is provided with a handheld handle 24, which contains a battery compartment and a stirring switch 25. The battery compartment is used to store the battery 21 that powers the stirring motor 22. Before ejecting the polyurethane adhesive material storage container 32, the stirring switch 25 is flipped, connecting the power supply circuit between the stirring motor and the battery 21. The stirring motor drives the stirrer 33 to rotate, and the paddles on the stirrer 33 break the brittle film, thereby mixing the polyurethane adhesive material components stored in the polyurethane adhesive material storage container 32, so that the polyurethane adhesive material forms a polyurethane with relatively uniform properties after curing.

[0039] The polyurethane adhesive material filling bin is provided with a bin cover 31 , and the bin cover 31 is used to block the polyurethane adhesive material filling bin outlet to prevent the polyurethane adhesive material storage container 32 from accidentally falling off from the polyurethane adhesive material filling bin.

[0040] When using the polyurethane adhesive material ejector of the present invention to apply glue to a remote glue application point, the polyurethane adhesive material storage container 32 is pressed into the polyurethane adhesive material filling bin, the stirring switch 25 is turned, and after stirring for a certain period of time, the stirring is stopped. Then, the launch switch 14 is turned, and the high-pressure gas of the pneumatic pressurizing device 13 launches the polyurethane adhesive material storage container 32 to the glue application point. The polyurethane adhesive material storage container 32 hits the glue application point and breaks into pieces. The mixed polyurethane adhesive material components in the polyurethane adhesive material storage container 32 cover the glue application point and then solidify, completing the glue application.

[0041] The present invention can be used to arrest people holding knives or similar objects to prevent the arresting persons from being injured, and can also be used to simply block cracks at a long distance.
