[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a glue spray gun with an anti-blocking function, which includes a gun body 1 and a rotating assembly. A support plate 2 is fixedly connected to the side wall of the gun body 1. A first sliding plate 3 is slidably connected to the side wall of the support plate 2. A pushing plate 4 is fixedly connected to the upper surface of the first sliding plate 3. A support block 5 is fixedly connected to the side wall of the first sliding plate 3. A rotating plate 6 is rotatably connected to the side wall of the first sliding plate 3. The rotating plate 6 is rotatably connected inside the support plate 2. A clamping block 7 is fixedly connected to the upper surface of the support block 5. A fixed ring 13 is fixedly connected to the side wall of the support plate 2. A nozzle 14 is arranged on one side of the gun body 1. A clamping column 9 is fixedly connected to the side wall of the nozzle 14. The outer wall of the clamping column 9 fits inside the fixed ring 13. The rotating plate 6 is rotatably connected to the side wall of the lower first sliding plate 3. A sliding column 11 is fixedly connected inside the support block 5. A spring 12 is arranged on the outer wall of the sliding column 11. The spring 12 is fixedly connected to the lower surface of the support block 5 and the upper surface of the lower support block 5. The sliding column 11 is slidably connected inside the lower support block 5. The clamping block 7 is engaged with the inside of the clamping column 9. A conveying assembly is arranged inside the gun body 1;

[0024] Specifically, pressing the pushing plate 4 starts the entire replacement process. The movement of the pushing plate 4 is not isolated. It drives the first sliding plate 3 to slide on the side wall of the support plate 2. As the first sliding plate 3 moves, the support block 5 also moves accordingly. The support block 5 not only plays a supporting role, but more importantly, its movement drives the rotating plate 6 to rotate inside the support plate 2. The rotation of the rotating plate 6 further drives the lower first sliding plate 3 to slide. This action seems simple, but it is one of the key steps to realize the replacement of the nozzle 14. At the same time, the movement of the support block 5 also drives the sliding column 11 to slide inside the lower support block 5. This sliding makes the mechanical structure more stable and reliable when replacing the nozzle 14. In this series of actions, the upper and lower support blocks 5 compress the spring 12. The spring 12, as an elastic element, plays a buffering and resetting role here. When the clamping block 7 no longer fixes the clamping column 9, the nozzle 14 can be pulled to move. The movement of the nozzle 14 drives the clamping column 9 to leave the inside of the fixed ring 13. At this time, different nozzles 14 can be easily replaced. The entire replacement process is simple and efficient, greatly improving the production efficiency.

[0025] Refer to Figure 1 , Figure 2 and Figure 4 , the conveying assembly includes a connecting pipe 8. The connecting pipe 8 is fixedly connected inside the gun body 1. The nozzle 14 is slidably connected to the outer wall of the connecting pipe 8. The rotating assembly includes a rotating column 15. The rotating column 15 is rotatably connected inside the gun body 1. One end of the rotating column 15 is fixedly connected with a fixed column 16. A handle 17 is fixedly connected to the outer wall of the fixed column 16. The handle 17 is rotatably connected to the top of the gun body 1. A stirring blade 18 is fixedly connected to the outer wall of the rotating column 15. The stirring blade 18 is rotatably connected inside the gun body 1;

[0026] Specifically, when the operator applies a moderate torque to the handle 17, it will start a smooth rotation movement with the axis as the base point. This movement is not isolated but is closely connected to the fixed column 16. The fixed column 16 is cleverly combined with the handle 17. When the handle 17 starts to rotate, the fixed column 16 will rotate synchronously. The fixed column 16 not only serves as a medium for transmitting power but also has a stable supporting role, providing a solid structural foundation for the entire device. The rotating column 15 is the next link in this series of movements. When the fixed column 16 rotates, the rotating column 15 will rotate accordingly, and its rotation speed and direction are consistent with those of the fixed column 16. This step is a key link in the entire operation process because it will directly drive the mixing blades 18 to work. When the rotating column 15 drives the mixing blades 18 to rotate, these mixing blades 18 will cut and mix the glue at a very high speed, effectively dispersing the glue and making it reach an ideal mixed state.

[0027] Refer to Figure 1 and Figure 4 Inside the gun body 1, a starting block 19 is fixedly connected. The output end of the starting block 19 is fixedly connected with a heating ring 10. The outer wall of the heating ring 10 is fixedly connected with a heat sleeve 20. The heat sleeve 20 is fixedly connected inside the gun body 1. The starting block 19, the heating ring 10, and the heat sleeve 20 are all located on the left and right sides of the gun body 1.

[0028] Specifically, start the starting block 19 on the right side of the glue gun. This operation will trigger the right heating ring 10 to start working and generate heat. Since the glue is not easily solidified when it comes into contact with heat, this step can effectively prevent the glue from clogging inside the glue gun. Next, the glue will pass through the inner wall of the right heat sleeve 20. During this process, the glue will be continuously heated by the right heating ring 10. This heating effect not only keeps the glue in a flowing state but also makes it easier for the mixing blades 18 to disperse the glue. The mixing blades 18 are to ensure that the glue is fully mixed inside the glue gun, thus preventing it from forming lumps or clogging in a certain area. Once the glue is dispersed by the mixing blades 18, the staff will further start the starting block 19 on the left side. This operation will activate the left heating ring 10 and make it start to heat up. In this way, the glue passing through the left side will be heated again, further enhancing its fluidity and reducing the possibility of sticking to the gun body 1 or the nozzle. Finally, the glue that has undergone double heating and mixing treatment will be transported to the inside of the nozzle 14 through the connecting pipe 8. During this process, since the glue has been fully heated and dispersed, it is not likely to form a clog during transportation, thus ensuring the smooth progress of the glue spraying process.

[0029] Working principle: When it is necessary to replace the nozzle 14 of different types or sizes, first, the staff moves by pressing the push plate 4. The movement of the push plate 4 drives the first sliding plate 3 to slide on the side wall of the support plate 2. The sliding of the first sliding plate 3 drives the support block 5 to move. The movement of the support block 5 drives the rotating plate 6 to rotate inside the support plate 2. The rotation of the rotating plate 6 drives the first sliding plate 3 on the lower side to slide. At the same time, the movement of the support block 5 drives the sliding column 11 to slide inside the lower support block 5, and at the same time, the upper and lower support blocks 5 squeeze the spring 12. At this time, the clamping block 7 no longer fixes the clamping column 9, and then the nozzle 14 can be pulled to move. The movement of the nozzle 14 drives the clamping column 9 to leave the inside of the fixed ring 13, and then different nozzles 14 can be replaced. When the staff needs to prevent the inside of the gun body 1 from being blocked during glue spraying, first start the right starting block 19, which makes the right heating ring 10 start to heat up, making the glue not easy to solidify. Then, when the glue passes through the inner wall of the right heat sleeve 20, turn the handle 17. The rotation of the handle 17 drives the fixed column 16 to rotate. The rotation of the fixed column 16 drives the rotating column 15 to rotate. The rotation of the rotating column 15 drives the stirring piece 18 to rotate. The rotation of the stirring piece 18 breaks up the glue. After being heated by the right heating ring 10, it is easier for the stirring piece 18 to break up the glue. After the glue is broken up, start the left starting block 19 to make the left heating ring 10 heat up to heat the passing glue again, making it more fluid and reducing the possibility of sticking to the gun body 1 or the nozzle. Finally, the glue is transported to the inside of the nozzle 14 through the connecting pipe 8, and at this time, it can prevent the glue from causing blockage during transportation.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
