[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution: a gluing device for the production of cardboard packaging boxes.

[0027] Example 1: As Figures 1-4The present invention provides the following technical solution: a gluing device for producing cardboard packaging boxes, comprising a limiting roller 8 and a limiting wheel 9, including a hydraulic cylinder 4 fixedly connected to the top surface of a support frame 3, a piston rod 5 inserted into the bottom of the hydraulic cylinder 4, the bottom end of the piston rod 5 fixedly connected to a mounting frame 6, a guide rail fixedly connected to one side surface of the mounting frame 6, and a glue spray head 7 provided at the bottom of the guide rail, a limiting roller 8 rotatably connected to one end of the mounting frame 6, and a limiting wheel 9 rotatably connected to the other end of the mounting frame 6, as shown. Figure 2 As shown, the mounting bracket 6 and the spray nozzle 7 form a telescopic mechanism with the hydraulic cylinder 4 via the piston rod 5, as... Figure 1 As shown, there are two limit wheels 9, and the limit wheels 9 are located on both sides of the inner wall of the mounting bracket 6.

[0028] In operation, the hydraulic cylinder 4 is connected to an oil pump and an oil storage tank via pipelines. The oil pump delivers hydraulic oil from the storage tank to the hydraulic cylinder 4 via pipelines, causing the piston rod 5 to extend. This allows adjustment of the height of the mounting frame 6, which in turn allows adjustment of the height of the limiting rollers 8 and 9. Depending on the thickness of the cardboard packaging, the limiting rollers 8 and 9, in conjunction with the conveyor belt 2 of the frame 1, vertically limit the cardboard packaging. The glue spray head 7 is connected to a gear pump and a glue tank via pipelines. The gear pump delivers glue from the glue tank to the glue spray head 7 via pipelines for glue application. Simultaneously, the horizontal position of the glue spray head 7 is adjusted via guide rails. The limiting rollers 9 and 8 effectively limit the cardboard packaging, preventing the cardboard packaging from shifting during glue application and affecting the accuracy of the glue application, thus effectively improving the glue application quality of the cardboard packaging.

[0029] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, also discloses a quick-release scraper assembly 10, including an insert 1001 mounted on the top surface of the mounting bracket 6. The external dimensions of the insert 1001 are consistent with the internal dimensions of the slot 11, such as... Figure 5 As shown, an adjusting disc 1002 is rotatably connected to one side surface of the insert block 1001, and a scraper body 1003 is fixedly connected to one side surface of the adjusting disc 1002. Figure 6 As shown, a fixing hole 1004 is provided on one side surface of the adjusting plate 1002, and the fixing holes 1004 are symmetrically distributed about the central axis of the adjusting plate 1002. The internal dimensions of the fixing holes 1004 are consistent with the external dimensions of the fixing rod 12.

[0030] In use, the scraper assembly 10 can be vertically inserted into the slots 11 on the top surface of the mounting frame 6 via the inserts 1001 at both ends, according to the need for flipping. The adjusting disc 1002 is rotatably connected to the inserts 1001. The adjusting disc 1002 can be rotated to a suitable angle as needed, and the scraper body 1003 will rotate accordingly. The tilt angle of the scraper body 1003 can be quickly adjusted as needed, effectively improving the uniformity and precision of glue application, ensuring that the glue is evenly applied to the surface of the cardboard packaging box, avoiding problems such as excessive glue layer or missed application, thereby improving the bonding strength and sealing performance of the cardboard packaging box. Figure 5 As shown, a through hole is provided on one side surface of the insert 1001, such as... Figure 6 As shown, when the fixing hole 1004 is aligned with the through hole of the insert 1001, rotate the fixing rod 12, as follows. Figure 4 As shown, the outer wall of the fixing rod 12 is provided with external threads, and the inner wall of the mounting bracket 6 is provided with internal threads. The fixing rod 12 generates linear displacement through the constraint of the threads, inserts into the through hole and the fixing hole 1004, and realizes the synchronous fixing of the plug block 1001 and the adjusting plate 1002. Conversely, the scraper assembly 10 can be quickly disassembled, effectively shortening the maintenance time of the scraper assembly 10 and improving maintenance efficiency.
