Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a special glue gun for non-cleaning foam glue. Background Art

[0002] Polyurethane caulk is a product that combines aerosol and polyurethane foam technologies. It's a special polyurethane product containing a polyurethane prepolymer, a blowing agent, and a catalyst in a pressure-resistant aerosol can. It can be used for sealing leaks, filling gaps, fixing bonds, and providing thermal insulation and sound insulation. It's particularly suitable for sealing and waterproofing between plastic-steel or aluminum alloy doors and windows and walls. Its surface drying time is generally around 10 minutes (at 20°C), but the drying time varies with ambient temperature and humidity. Generally, it takes 4-6 hours in summer and 24 hours or more in winter at temperatures around freezing. Under normal operating conditions (and with a covering), its service life is estimated to be at least ten years. The cured foam maintains excellent elasticity and adhesion within a temperature range of -10°C to 80°C. The cured foam performs as a caulk, bond, and seal. Flame-retardant polyurethane caulks can achieve Class B and C flame retardancy ratings.

[0003] At present, it is known through searching that the Chinese patent number is: CN202222525302.3, which is a special glue gun for polyurethane foam sealant, including a glue gun body and an adapter mechanism, wherein the adapter mechanism is located on the right side of the bottom of the glue gun body; the adapter mechanism includes a connecting block fixedly installed on the right side of the bottom of the glue gun body, a connecting groove is provided at the bottom of the connecting block, and movable grooves are provided on the left and right sides of the connecting block, a fixed block is fixedly installed in the middle of the movable groove, a threaded rod with both ends penetrating and extending to the outside of the fixed block is movably installed inside the fixed block, the front and back sides of the outer surface of the threaded rod are threadedly connected to a connecting rod with one end penetrating the connecting block and extending to the inside of the connecting groove, and a clamping block is fixedly installed between the opposite sides of the connecting rod, This polyurethane foam sealant is applied with a special glue gun. By setting an adapter mechanism, the distance between the two clamping blocks can be adjusted by twisting the threaded rod until it contacts and fixes the bottle mouth of the glue jar. This completes the fixation of the glue jar, making it suitable for glue jars of different sizes. The anti-slip pad strengthens the firmness of the connection and can effectively prevent the glue jar from falling off. The limit block can prevent the threaded rod from deflecting or shaking, thereby enhancing the stability of the overall structure.

[0004] However, when constructing in a confined space close to the top, the bottle will hit the ceiling, causing a gap close to the top, making it impossible to complete the gluing construction smoothly. At the same time, due to the lack of an independent switch, a special cleaning agent must be used to clean the colloid residue in the glue gun barrel after each use. If it is not cleaned, the colloid will dry and block the glue gun, making the glue gun unusable. Utility Model Content

[0024] Specifically, by providing a connection control component, the storage component is placed under the glue gun body 1. The storage component is at the bottom. When constructing in a confined space close to the ceiling, the gluing construction can still be completed smoothly. At the same time, the connection control component is used to connect the storage component and the glue gun body 1. An independent ball valve switch is set in the middle of the connecting pipe 19. In this way, each time the gluing is completed, the ball valve can be operated to close the connection between the storage component and the glue gun body 1, and the remaining glue in the glue gun body 1 can be cleaned. In this way, the colloid inside the glue gun body 1 can be cleaned without residual colloid, and there is no need to clean the glue gun additionally. At the same time, the ball valve switch also has the function of controlling the glue output flow rate. Using this glue gun can save glue, save time, and save construction costs.

[0025] In this embodiment, the glue gun body 1 also includes a connecting frame 2, a glue discharge pipe 4, a glue discharge head 5, a flow switch 6, a push rod 7, a short shaft 8, a grip 9 and a glue gun wrench 10. The grip 9 is fixedly installed at the bottom of the connecting frame 2, and the other end of the connecting frame 2 is fixedly connected to the outer wall of the colloid cylinder 3. One end of the push rod 7 is fixedly connected to the flow switch 6, and one end of the push rod 7 is partially threadedly connected to the connecting frame 2. The middle section of the push rod 7 is limited and movably inserted into the interior of the glue gun wrench 10. The top of the glue gun wrench 10 is movably connected to the connecting frame 2 through the short shaft 8. The other end of the push rod 7 is movably inserted into the interior of the colloid cylinder 3. One end of the colloid cylinder 3 is connected to the glue discharge pipe 4, and the other end of the glue discharge pipe 4 is fixedly connected to the glue discharge head 5.

[0026] Specifically, when in use, hold the handle 9 of the glue gun body 1 with your hand, and then press the glue gun wrench 10 with your finger, so that the push rod 7 moves, so that the colloid can be pushed to the colloid cylinder 3 and the glue outlet pipe 4 and then sprayed out through the glue outlet head 5. The flow rate of the colloid can be controlled by adjusting the flow switch 6. The flow switch 6 can be turned to make the push rod 7 threadedly connected to the connecting frame 2, thereby limiting the movement of the push rod 7. When the push rod 7 needs to be opened and moved, the flow switch 6 is turned to disengage the push rod 7 from the connecting frame 2. The use technology is the existing technology, such as glue guns and other equipment.

The card joint 14 is limitedly inserted into the inside of the card groove 21, and the limiting ring 13 is in contact with the bottom of the threaded seat 15.

[0028] Specifically, a glue bottle body 12 with a threaded seal is used, which facilitates the rapid replacement of the glue bottle body 12 and is more convenient and quick to use. At the same time, a snap-on card joint 14 and a snap-on slot 21 are used to make the connection between the storage component and the connection control component more sealed, less prone to leakage, and improve the sealing performance of the device. A limit ring 13 is used to facilitate judgment of whether the threaded seat 15 is rotated to the appropriate position.

[0029] In summary, compared with the existing technology, the special glue gun for washing foam glue has at least the following beneficial effects: by providing a connection control component, the storage component is placed under the glue gun body 1, and the storage component is at the bottom. When constructing in a confined space close to the ceiling, the gluing construction can still be completed smoothly. At the same time, the connection control component is used to connect the storage component and the glue gun body 1, and an independent ball valve switch is set in the middle of the connecting pipe 19. In this way, each time the gluing is completed, the ball valve can be operated to close the connection between the storage component and the glue gun body 1, and the remaining glue in the glue gun body 1 can be cleaned. In this way, the colloid inside the glue gun body 1 can be cleaned without residual colloid, and there is no need to clean the glue gun additionally. At the same time, the ball valve switch also has the function of controlling the glue output flow rate. Using this glue gun can save glue, save time, and save construction costs.
