Detailed implementation mode

[0023] The following combines the attached Figures 1 to 6 to describe the present utility model in detail.

[0024] The present utility model is a label laminating machine with an automatic glue coating function, including a machine base 1, and the machine base 1 is further provided with: a first material unwinding device 2 for unwinding printed paper; a glue coating device 3 for automatically coating glue on the material unwound by the first material unwinding device 2; a second material unwinding device 4 for unwinding label base paper; a film laminating device 5 for pressing and bonding the side of the printed paper coated with glue to the material unwound by the second material unwinding device 4 into one body; and a winding device 6 for automatically winding the laminated material. In addition to the film laminating function, this technical solution also has an automatic glue application function, so that the printed label material roll can directly complete the glue application and film laminating processes after unwinding through this equipment, realizing in-line production and effectively improving the forming efficiency of the label.

[0025] Preferably, the glue coating device 3 includes a glue injection device 31, a drive device 32, and a first rubber roller 33, a second rubber roller 34, and a third rubber roller 35 arranged in sequence from top to bottom; the first rubber roller 33 and the third rubber roller 35 are both in contact with the surface of the second rubber roller 34, and a glue injection position 36 is formed between the first rubber roller 33 and the second rubber roller 34; the drive device 32 drives the second rubber roller 34 to move, and the glue injection device 31 injects glue into the glue injection position 36. When the first roll of material passes between the second rubber roller 34 and the third rubber roller 35, the drive device 32 drives the second rubber roller 34 to rotate, and the second rubber roller 34 brings the glue stored in the glue injection position 36 onto the first roll of material, thereby realizing the automatic glue application function. The overall structure of this embodiment is novel, flexible and simple, and the automatic glue application of the label is realized at low cost.

[0026] As shown Figure 2 in FIG. 2, the driving device 32 includes a servo motor 321 and a gear a322. A gear b323 and a gear c324 are coaxially assembled at the end of the second rubber roller 34, and a gear d325 is assembled at the end of the third rubber roller 35. The gear a322 meshes with the gear b323, and the gear c324 meshes with the gear d325. This structure enables the driving device 32 to drive the first rubber roller 33 and the second rubber roller 34 to move synchronously at the same time.

[0027] Preferably, the glue injection device 31 includes a glue injector 311. The cross-section of the glue injector 311 is an inverted triangle. A glue inlet 312 is provided at the top of the glue injector 311, and a plurality of glue outlets 313 are evenly distributed at the bottom of the glue injector 311. The inverted triangle-shaped glue injector 311 enables a small amount of the accumulated glue inside to be evenly discharged from the glue injector 311 each time, preventing too much glue from being discharged at a single time.

[0028] When the glue injection device 31 injects glue into the glue injection position 36, the excess glue will flow out from both ends of the second rubber roller 34 under the action of gravity. To avoid wasting this part of the glue, a recovery device 7 for recovering the excess glue is further provided below the glue coating device 3.

[0029] As an embodiment, the recovery device 7 includes a material receiving tray 71. The material receiving tray 71 is arranged below the glue coating device 3. The material receiving tray 71 directly receives the excess glue. At the same time, the material receiving tray 71 is connected with a discharge nozzle 72, and the received glue can be directly recovered and reused through the discharge nozzle 72.

[0030] To further improve the technical solution, the recovery device 7 further includes a spiral deflector 73, a funnel 74 and a confluence trough 75 which are connected in sequence. The confluence trough 75 is connected with the discharge nozzle 72; the spiral deflector 73 is assembled at both ends of the second rubber roller 34. The above components have a guiding function to facilitate the full recovery and utilization of the glue.

[0031] In the present utility model, the film laminating device 5 includes an upper film laminating roller 51 and a lower film laminating roller 52 which are arranged opposite to each other up and down; wherein, the lower film laminating roller 52 is connected with a driver 53. During the film laminating process, the lower film laminating roller 52 can drive the upper film laminating roller 51 to rotate, so that the film material is continuously conveyed forward.

[0032] Preferably, lifting adjustment devices 8 are further provided at both ends of the upper film laminating roller 51. The lifting adjustment devices 8 enable the upper film laminating roller 51 to move up and down, so as to adjust the gap between the upper and lower film laminating rollers 52, and at the same time, it is also convenient for manual pre-threading of the film material before the machine starts.

[0033] As shown Figure 4As shown in the figure, the machine base 1 is provided with a sliding groove 11 corresponding to the lifting and adjusting device 8; the lifting and adjusting device 8 includes a slider 81 and an adjusting handwheel 82. The slider 81 is movably sleeved on the end of the upper film covering roller 51, and the slider 81 is slidably connected to the sliding groove 11. The bottom end of the adjusting handwheel 82 is connected to the slider 81. A threaded portion is provided in the middle of the adjusting handwheel 82. The adjusting handwheel 82 is threadedly connected to the machine base 1 through the threaded portion. Rotating the adjusting handwheel 82 can drive the slider 81 to move up and down along the sliding groove 11, so as to realize the up and down displacement of the upper film covering roller 51.
