[0002] The glue gun is a tool commonly used to apply glue. It is widely used in many industries such as building decoration, electronic products, automobile manufacturing, ships and containers. When using the glue gun, you first need to pull the pusher to the last position, then put the mixing tube filled with glue into the fixing groove of the glue gun and replace the appropriate mixing nozzle. After that, you only need to operate the wrench to start the dispensing operation.

[0003] In industries such as automobile manufacturing, glue guns are important equipment. However, after a period of use, the nozzle may be clogged due to the drying of glue. These dried glues are usually hard and sticky, making them difficult to remove. The current cleaning method is mainly to disassemble the glue gun and soak and rinse the barrel and nozzle separately, which not only increases the workload of cleaning, but also prolongs the cleaning time. In addition, traditional cleaning methods are usually done manually, and the cleaning agents used are formulated with chemical substances, and long-term contact may cause harm to the health of workers. This method can only remove larger pieces or residual glue with lower hardness, and it is difficult to completely clean residual glue with higher hardness. As the residual glue accumulates in the glue gun, it may eventually cause the glue gun to be unusable and scrapped, which greatly increases production costs. Summary of the invention

[0024] In order to make the technical personnel in this field better understand the present application scheme, the following will be combined with the attached Figure 1-6 , a clear and complete description of the technical solutions in the embodiments of the utility model is given.

[0025] An automatic induction glue gun nozzle cleaning device comprises a housing 1, a cleaning box 2, a driving member 5, and a driving motor 6. A motor control board is placed in the housing 1, and the motor control board is electrically connected to the driving motor 6. Figure 1 As shown;

[0026] The cleaning box 2 is provided with a cleaning chamber 22, in which two cleaning brush heads 4 are arranged, a rotating member 3 is rotatably arranged in the cleaning chamber 22, a receiving chamber for receiving the cleaning brush head 4 is arranged at the center of the rotating member 3, a mounting seat 41 of the cleaning brush head 4 comprises a fixed shaft 411 and a movable shaft 412, the rotating member 3 is rotatably connected to the fixed shaft 411 of the cleaning brush head 4, the movable shaft 412 of the cleaning brush head is rotatably slidably connected to the connecting groove 51 of the driving member 5, and the rotating member 3 is also provided with a limiting structure for limiting the rotation angle of the cleaning brush head 4 around the axis of the fixed shaft 411, such as Figure 2 As shown;

[0027] The rotating member 3 includes an upper rotating member 31 and a lower rotating member 32. A connecting rod 34 is provided between the upper rotating member 31 and the lower rotating member 32 to connect the two members into a whole, so that the upper rotating member 31 and the lower rotating member 32 rotate synchronously. A deep groove ball bearing 30 is connected between the upper rotating member 31 and the cleaning box 2. The outer wall of the upper rotating member 31 and the inner wall of the deep groove ball bearing 30 are interference fit. The outer wall of the deep groove ball bearing 30 and the inner wall of the cleaning chamber 22 are interference fit to prevent the rotating member 3 from shaking when rotating. The upper rotating member 31 is provided with a limiting groove 33 as a limiting structure. The limiting groove 33 includes a first limiting edge 331 and a second limiting edge 332. The middle part of the upper rotating member 31 is also provided with an upper through hole 35 for the glue nozzle of the glue gun to enter the accommodating cavity. The upper rotating member 31 is detachably connected to a fixed shaft mounting plate 39 by bolts, such as Figure 3 , Figure 4 The lower rotating member 32 is provided with a cleaning brush head mounting groove 37 adapted to the size of the cleaning brush head 4 to ensure the stability of the cleaning brush head 4 during the closing and separation movement, the lower rotating member 32 is also provided with a lower through hole 36 for accommodating the driving member 5, such as Figure 5 shown.

[0028] The fixed shaft mounting plate 39 and the lower rotating member 32 are both provided with a fixed shaft mounting hole 38 .

[0029] Before cleaning, add a certain amount of cleaning liquid into the cleaning chamber 22. The motor control board starts the driving motor 6, and first the driving motor 6 drives the driving member 5 to rotate in a clockwise direction. Since the movable shaft 412 of the cleaning brush head 4 is rotatably slidably connected to the connecting groove 51 of the driving member 5, the upper end of the fixed shaft 411 is rotatably connected to the fixed shaft mounting hole 38 of the fixed shaft mounting plate 39, and the lower end of the fixed shaft 411 of the cleaning brush head 4 is rotatably connected to the fixed shaft mounting hole 38 of the lower rotating member 32. When the driving member 5 rotates, the movable shaft 412 slides inward in the connecting groove 51 and the two movable shafts 412 approach each other, so that the mounting seat 41 rotates around the axis of the fixed shaft mounting hole 38 toward the center of the rotating member 3, and then the two cleaning brush heads 4 approach each other and can clamp the glue nozzle of the glue gun entering the cleaning box 2. Then the driving motor 6 drives the driving member 5 to continue rotating. When the mounting seat 41 abuts against the first limiting edge 331, the rotational force of the driving motor 5 is transmitted to the rotating member 3. When the rotational force is greater than the friction between the rotating member 3 and the inner wall of the cleaning chamber 22, the rotating member 3 begins to rotate clockwise around its axis, thereby driving the cleaning brush head 4 on the rotating member 3 to rotate clockwise together, thereby realizing the closing of the cleaning brush head 4 and the rotation of the rotating member 3.

[0030] When cleaning is finished, the motor control board controls the drive motor 6 to rotate counterclockwise, and the drive motor 6 drives the drive member 5 to rotate counterclockwise. When the drive member 5 rotates, the movable shaft 412 slides outward in the connecting groove 51, so that the movable shafts 412 move away from each other, thereby driving the mounting seat 41 to rotate around the axis of the fixed shaft mounting hole 38 in a direction away from the center of the rotating member 3, thereby increasing the distance between the two cleaning brush heads 4 and releasing the glue gun nozzle. The drive motor 6 drives the drive member 5 to continue rotating. When the mounting seat 41 abuts against the second limiting edge 332, the rotational force of the drive motor 5 is transmitted to the rotating member 3. When the rotational force is greater than the friction between the rotating member 3 and the inner wall of the cleaning chamber 22, the rotating member 3 begins to rotate counterclockwise around its axis, thereby realizing the separation of the cleaning brush head 4 and the rotation of the rotating member 3.

[0031] In some embodiments, the motor control board is installed inside the housing 1, responsible for receiving the sensing signal of the sensing member 7 and controlling the start and stop of the driving motor 6. The sensing member 7 is used to sense the position of the glue gun. A cleaning program is preset in the motor control board, and the operations of keeping the cleaning brush head 4 separated and rotating the rotating member 3, and closing the cleaning brush head 4 and rotating the rotating member 3 are performed multiple times to ensure that the glue nozzle of the glue gun is fully cleaned. When the cleaning brush head 4 is kept separated and the rotating member 3 rotates, the hardened residual glue on the scrubbing head 43 is taken away by the water flow to maintain the cleaning effect.

[0032] In addition, in order to improve the sealing and waterproof properties of the device, the drive motor 6 is connected to the drive member 5 through the transmission shaft 61, and the cleaning box 2 is provided with a sealing sleeve adapted to the size of the transmission shaft 61. The upper and lower ends of the inner surface of the sealing sleeve are provided with sealing ring installation grooves, and an O-ring is provided in the sealing ring installation groove. The transmission shaft 61 is installed in the sealing sleeve. These designs ensure that the cleaning liquid will not leak during the cleaning process, and also protect the drive motor 6 from moisture.

[0033] In some embodiments, the cleaning brush head 4 in the cleaning chamber 22 is composed of a mounting seat 41, a mounting seat 42 and a scrubbing head 43, and the scrubbing head 43 is detachably connected to the mounting seat 41 by bolts from the mounting seat 42. Figure 6 As shown, it is convenient to replace and clean. The scrubbing head 42 is made of a brush or a sponge to adapt to different glue types and glue nozzle styles.

[0034] In some embodiments, a bracket 8 is also provided, the housing 1 is provided on one side of the bracket 8, and the cleaning box 2 is provided near the other side of the bracket 8, which is convenient for wiring and makes the structure compact. At the same time, in order to avoid splashing of the cleaning liquid during the cleaning process, a cleaning box cover 21 is also provided above the cleaning box.

[0035] The cleaning box cover 21 is provided with a through hole for accommodating the glue nozzle of the glue gun. The inlet and outlet of the housing 1 are both equipped with waterproof connectors.

[0036] In some embodiments, the housing 1 is a sheet metal part, and a waterproof rubber strip is installed at the position where the sensing part 7 is installed in the housing 1 to effectively prevent dust and water vapor from penetrating.

[0037] In some embodiments, a drain port is provided below the cleaning box 2, and the drain port is externally connected to a ball valve 9. After the ball valve 9 is opened, the cleaning liquid is discharged through the drain port of the cleaning box 2. It is convenient to replace the cleaning liquid and maintain a good cleaning effect.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
