Description

Technical Field

[0001] This utility model relates to the field of glue spraying equipment technology, and in particular to a glue spraying device for a two-component glue gun. Background Technology

[0002] A caulking gun is a tool for applying caulking agent. To improve the drying effect of polyurethane foam sealant, it can be mixed with a drying aid (curing agent).

[0003] Most caulking guns on the market for extruding polyurethane foam sealant are industrial products, inconvenient to operate, and some require electricity, making them unsuitable for simple household tasks. To better suit household use and reduce the professional requirements of operation, several caulking guns are now available that can mix foam adhesive and drying agent before spraying. For example, Chinese invention patent CN202510943447.0 discloses a spraying device and method for simultaneously mixing foam adhesive and drying agent. In this solution, during spraying, pressing down the wrench pushes the spraying block downwards through the extrusion block. The spraying block drives the first and second connecting pipes downwards simultaneously, allowing the foam adhesive and drying agent in the spraying can and auxiliary can to converge into the main spraying pipe through the first and second spraying pipes, mix in the discharge chamber, accelerate through the contraction orifice, and then pass through the spiral blades in the spraying chamber to form a uniformly mixed jet stream. However, in actual single-handed glue spraying operations, both the expanding foam can and the drying agent can need to be used upside down, with the wrench located below the expanding foam can. This means that the user's hand needs to grasp the expanding foam can while simultaneously pulling the trigger (for example, when the thumb and forefinger grasp the expanding foam can, the little finger needs to reach the trigger and pull the wrench), which is very inconvenient, does not conform to normal human hand operation logic, and is quite strenuous. Furthermore, when not in use, the fixing rod needs to be removed from the limiting hole to release the wrench, which is cumbersome and continues to spray glue during this process, causing unnecessary waste, and it is impossible to control and stop glue spraying at any time. In addition, in existing technologies, the expanding foam can and the drying agent can are directly fixed to the glue spraying device, making them impossible to disassemble and replace, or replacing them is very cumbersome. They are for single use only; once the expanding foam in the expanding foam can and the drying agent in the drying agent can are used up, they cannot be reused, resulting in resource waste.

[0050] Detailed implementation plan: See below Figures 1-12 This utility model is a two-component glue gun spraying device, comprising:

[0051] Mounting base 1, the upper end of which is provided with a first mounting port 15 for mounting the foam adhesive can 5 and a second mounting port 16 for mounting the drying agent can 6;

[0052] The sealing component 2 is installed in the mounting base 1, and the upper end of the sealing component 2 is provided with a first connecting pipe 21 and a second connecting pipe 22;

[0053] The adhesive spraying assembly 3 is installed on one side of the sealing component 2, and the first connecting pipe 21 and the second connecting pipe 22 are both connected to the adhesive spraying assembly 3.

[0054] The mounting base 1 has a handle 11 on one side, and the adhesive spraying device also includes:

[0055] The rotating component 4 includes an adapter plate 41 rotatably mounted below the mounting base 1, and a trigger 42 disposed on one side of the adapter plate 41. A handle 11 is disposed on one side of the trigger 42, and at least one flange 44 is provided on the upper end surface of the adapter plate 41.

[0056] The trigger 42 is in the dispensing state when pulled close to the handle 11. In the dispensing state, the flange 44 is used to cooperate to squeeze the sealing member 2 upward. The sealing member 2 moves upward and drives the first connecting pipe 21 to squeeze and open the valve of the foam can 5, and the second connecting pipe 22 to squeeze and open the valve of the drying agent can 6.

[0057] Note: Please refer to Figure 1 , Figure 3 and Figure 4 When performing the glue spraying operation, the foam glue can 5 and the drying agent can 6 need to be inverted. Therefore, at this time, the foam glue can 5 and the drying agent can 6 are both located above the mounting base 1, and the handle 11 and the trigger 42 are located below the mounting base 1.

[0058] As a preferred embodiment of this example, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As can be seen, there are two flanges 44. In the dispensing state, the two flanges 44 respectively push the sealing part 2 to the positions corresponding to the first connecting pipe 21 and the second connecting pipe 22.

[0059] In this embodiment, by providing a handle 11 on one side of the mounting base 1, the handle 11 can be grasped to pull the trigger 42 when performing glue spraying operations with one hand, making the operation more labor-saving and convenient to use.

[0060] Here, when the sealing component 2 moves upward, the two flanges 44 respectively press against the positions corresponding to the first connecting pipe 21 and the second connecting pipe 22, thereby ensuring uniform force and causing the first connecting pipe 21 to press upward and open the valve of the foam can 5, and causing the second connecting pipe 22 to press upward and open the valve of the drying agent can 6.

[0061] Then, please see Figure 7 and Figure 8 As can be seen, in this embodiment, one end of the mounting base 1 is provided with two mounting sleeves 14 for cooperating with the mounting shaft 46, and one end of the rotating member 4 is provided with a bushing 43 for rotatingly sleeved on the shaft 46. The bushing 43 is disposed between the two mounting sleeves 14.

[0062] In this embodiment, two mounting sleeves 14 are provided as a first mounting sleeve and a second mounting sleeve. When it is necessary to install the rotating part 4 on the mounting base 1, the bushing 43 is first placed between the first mounting sleeve and the second mounting sleeve, and then the shaft 46 passes through the first mounting sleeve, the bushing 43 and the second mounting sleeve in sequence. The end of the shaft 46 is screwed onto the second mounting sleeve, thus completing the installation of the rotating part 4.

[0063] Next, please refer to Figure 3 , Figure 7 and Figure 8 As can be seen, in this embodiment, the lower left and right sides of the mounting base 1 are respectively provided with positioning blocks 17, and the positioning blocks 17 are provided with positioning grooves. The left and right sides of the adapter plate 41 are respectively provided with positioning rods 45, which are placed in the positioning grooves and can move in the positioning grooves.

[0064] Here, the positioning groove and positioning rod 45 are used to position the left and right positions of the rotating part 4 during the rotation process, so that the rotating part 4 will not wobble in the left and right direction, thus enabling the trigger 42 to be pulled more stably.

[0065] Then, please see Figures 8-10As can be seen, in this embodiment, the mounting base 1 is provided with a sliding groove 12 for the sealing component 2 to be slidably installed in the vertical direction. A reset structure is provided between the sealing component 2 and the mounting base 1. The mounting base 1 is also provided with a clearance port 13, which is connected to the sliding groove 12. The adhesive spraying component 3 extends from the sliding groove 12 to the outside of the mounting base 1 through the clearance port 13.

[0066] In this embodiment, the sliding groove 12 allows the sealing component 2 to move up and down more smoothly along the sliding groove 12, and the opening 13 allows the adhesive spraying assembly 3 to be placed.

[0067] As another preferred embodiment of this example, please refer to Figure 11 and Figure 12 As can be seen, the adhesive spraying assembly 3 includes:

[0068] The first pipe 31 has one end connected to the first connecting pipe 21;

[0069] The second pipe 32 has one end connected to the second connecting pipe 22;

[0070] The drying agent tube 34 is connected at one end to the second pipe 32;

[0071] A branch pipe 331 is connected at one end to a first pipe 31 and at the other end to a main pipe 33. A first channel is provided in the branch pipe 331. The main pipe 33 is sleeved on the outside of the dryer pipe 34. A second channel is provided between the main pipe 33 and the dryer pipe 34. The first channel and the second channel are connected. Furthermore, a sealing section 341 for sealing one end of the main pipe 33 is provided at one end of the dryer pipe 34.

[0072] The mixing pipe 35 is connected at one end to the main pipe 33, and the dryer pipe 34 extends into the mixing pipe 35 at the end away from the second pipe 32.

[0073] Working principle of the adhesive spraying assembly 3: After grasping the handle 11 and pulling the trigger 42, the sealing member 2 can be driven to move upward. At this time, the first connecting pipe 21 and the second connecting pipe 22 located on the sealing member 2 will squeeze upward and open the valves of the foam adhesive can 5 and the drying agent can 6. The foam adhesive flows into the first pipe 31 through the first connecting pipe 21 and continues to flow into the first channel of the branch pipe 331. Since the first channel and the second channel are connected, it will continue to flow into the second channel. At the same time, the drying agent flows into the second pipe 32 through the second connecting pipe 22 and continues to flow into the drying agent pipe 34. Since the end of the drying agent pipe 34 away from the second pipe 32 extends into the mixing pipe 35, and one end of the mixing pipe 35 is connected to the main pipe 33, the foam adhesive flowing out of the second channel and the drying agent flowing out of the self-drying agent pipe 34 are mixed in the mixing pipe 35 (the mixing pipe 35 is long enough to allow the foam adhesive and the drying agent to be fully mixed). After mixing, it is sprayed out of the mixing pipe 35.

[0074] After releasing trigger 42, the reset structure can work together to reset the sealing part 2 downwards, thereby closing the valve of the foaming glue tank 5 and the valve of the drying agent. The glue spraying device will stop spraying glue, and the user can control the glue spraying time and glue spraying stop time at any time, making operation convenient.

[0075] Then, please see Figure 11 As can be seen, in this embodiment, the reset structure includes two annular cylinders 23 disposed at the lower end of the sealing member 2, and at least one screw hole 18 disposed at the bottom of the groove 12. The sealing member 2 is provided with at least one screw 24. After the screw 24 passes through the annular cylinder 23, one end is screwed into the screw hole 18. A spring 25 is sleeved on the outside of the screw 24. One end of the spring 25 abuts against the bottom of the groove 12, and the other end abuts against the sealing member 2.

[0076] Working principle of the reset structure: When the trigger 42 is pulled and the sealing member 2 is driven to move upward, the spring 25 is compressed and accumulates elastic force. After the trigger 42 is released, the spring 25 returns to its deformation and drives the sealing member 2 to reset downward.

[0077] In addition, please see Figure 4 As can be seen, in order to facilitate hand gripping, in this embodiment, the handle 11 is placed at an angle downwards, and the handle 11 and the mounting base 1 are integrally formed.

[0078] For more details, please see Figure 10 and Figure 11 In this embodiment, the clearance port 13 extends horizontally, the adhesive spraying assembly 3 is placed horizontally, and the end of the main pipe 33 used to connect to the mixing pipe 35 is provided with anti-slip texture 332. Here, the anti-slip texture 332 makes the mixing pipe 35 more securely installed on the main pipe 33.

[0079] It should be noted that in existing technologies, expanding foam cans and drying agent cans are generally directly fixed to the adhesive spraying device and are mostly for single use. Once the expanding foam in the expanding foam can and the drying agent in the drying agent can are used up, they cannot be reused. In this embodiment, by providing a first mounting port for mounting the expanding foam can and a second mounting port for mounting the drying agent can at the upper end of the mounting base, the expanding foam can and drying agent can be easily replaced, and the adhesive spraying device can be reused repeatedly.

[0080] The above description of the glue spraying device for a two-component glue gun of this utility model is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
