For example, Chinese utility model patent CN215792133U discloses an integrated handle-attaching mechanism, which includes a frame, a tear-cutting assembly, a gluing assembly, a handle-attaching assembly, and a pressure roller assembly. The tear-cutting assembly includes a tear-cutting knife mounted on a mounting roller. The gluing assembly includes a gluing roller and a glue box. The handle-attaching assembly is mounted on a mounting frame. The pressure roller assembly includes a pressure roller mounted on a mounting shaft. Its features... The machine is characterized by the following: a movable frame is movably mounted on the frame, and the movable frame is connected to a movable adjustment component. The mounting roller, gluing roller, glue box, mounting frame, and mounting shaft are all connected to the movable frame. The sticking machine applies glue to the paper bag by rotating the gluing roller, which then applies glue from the glue box to the sticking position. This method has a complex structure. Furthermore, when the sticking machine is not in use, the glue box and gluing roller need to be cleaned promptly; otherwise, the glue will solidify on the roller and box, making them unusable and inconvenient to use.

[0021] See attached document Figures 1 to 5 The adhesive spraying mechanism of the sticking machine of this utility model will be described in further detail.

[0022] A glue spraying mechanism for a glue applicator includes a glue storage tank 2 for storing glue, a glue delivery pipe 3, and a nozzle 4 fixedly mounted on a frame 1; a screw pump 6 is provided on the glue storage tank 2, and the screw pump 6 delivers the glue in the glue storage tank 2 to the nozzle 4 through the glue delivery pipe 3; one end of the glue delivery pipe 3 is connected to the glue storage tank 2, and the other end is connected to the nozzle 4;

[0023] When the glue spraying mechanism applies glue to the paper 5, the nozzle sprays the glue delivered from the glue storage tank 2 to the nozzle 4 via the glue delivery pipe 3 onto the sticking position of the paper 5, replacing the method of brushing glue onto the paper 5 using a glue roller in the prior art. It eliminates the need to set up a glue box and glue roller in the frame 1, simplifying the mechanical structure of the sticking machine. At the same time, after the sticking process is completed, there is no need to clean the glue box and glue roller, saving cleaning time for the user. In addition, there is no need to add glue to the glue box in the frame 1 from time to time; only the glue storage tank 2 on one side of the frame 1 needs to be added, making the adding operation simpler and more convenient.

[0024] The frame 1 is provided with a mounting part 11 for mounting the nozzle 4. One end of the mounting part 11 is fixed to the frame 1, and the other end is provided with a mounting rod 111. The mounting block 41 at the upper end of the nozzle 4 is provided with a mounting hole 411 that matches the mounting rod 111. The mounting block 41 is sleeved on the mounting rod 111 through the mounting hole 411. The nozzle 4 can slide along the mounting rod 111 through the mounting hole 411, thereby adjusting the position of the nozzle aligned with the paper 5. This allows the glue spraying mechanism to perform glue application operations on paper bags of different specifications and different label positions, making it more versatile.

[0025] The mounting block 41 is provided with a plurality of set screw holes 412, which are connected to the mounting holes 411. The set screws pass through the set screw holes 412 and abut against the mounting rod 111 in the mounting holes 411, thereby locking the nozzle 4 onto the mounting rod 111. After the nozzle 4 has been adjusted in its installation position, the nozzle 4 can be installed and fixed simply by screwing the set screws into the set screw holes 412, which abut against the mounting rod 111.

[0026] The glue storage tank 2 is connected to two glue delivery pipes 3, and the frame 1 is equipped with two nozzles 4 that are respectively connected to the two glue delivery pipes 3. The two glue delivery pipes 3 simultaneously deliver glue to the corresponding nozzles 4, and the two nozzles 4 simultaneously spray glue on the two sticking positions of the paper 5, thereby improving the glue application efficiency of the paper 5 and increasing production efficiency.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
