[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figures 1 to 3 The gluing device includes: a frame 100, which is provided with a supporting roller 110; a driving mechanism, which is arranged on the frame 100, and includes a first linear module 210 and a sensing component, the sensing component is arranged at the movable end of the first linear module 210, and the sensing component is electrically connected to the first linear module 210; a glue rolling mechanism 300, which is arranged above the supporting roller 110, and the first linear module 210 drives the glue rolling mechanism 300 to move in a vertical direction; wherein, the sensing component includes a movable block 222 and a sensor 221, the movable block 222 is movably arranged in the glue rolling mechanism 300 along the vertical direction, the sensor 221 is arranged on the frame 100, and the movable block 222 can trigger the sensor 221.

[0029] The booklet is sent to the bottom of the glue rolling mechanism 300 via a conveyor. The first linear module 210 drives the glue rolling mechanism 300 to move downward. First, the movable block 222 contacts the booklet. After the movable block 222 contacts the booklet, the glue rolling mechanism 300 continues to move downward and contacts the booklet. The movable block 222 moves upward relative to the glue rolling mechanism 300 and triggers the sensor 221. The glue rolling mechanism 300 stops moving downward. The glue rolling mechanism 300 then applies glue to the booklet, automatically adapting to the thickness of the booklet, which is convenient and fast. It should be noted that by adjusting the trigger stroke of the movable block 222, the pressure applied by the glue rolling mechanism 300 to the booklet can be adjusted to achieve different glue rolling effects. It should be noted that the first linear module 210 is an electric linear slide module.

[0030] It is understandable that, referring to Figure 1 and Figure 2The glue rolling mechanism 300 includes a first glue box 310, a glue roller 330, and a glue coating roller 340. The glue roller 330 and the glue coating roller 340 abut against each other to form a glue storage position 360. The glue box delivers glue to the glue storage position 360. The glue roller 330 and the glue coating roller 340 are both arranged horizontally and rotatably disposed within the first glue box 310. After the glue is delivered from the first glue box 310 to the glue storage position 360, the glue is stored in the glue storage position 360. After the glue coating roller 340 and the glue rolling roller 330 rotate, the glue evenly adheres to the glue coating roller 340 and the glue rolling roller 330. The first glue box 310 continuously replenishes glue to the glue storage position 360, ensuring that the surfaces of the glue coating roller 340 and the glue rolling roller 330 are always coated with glue, thereby maintaining glue rolling stability.

[0031] Specifically, refer to Figures 1 to 3 Second glue boxes 320 are located on both sides of the first glue box 310. The first glue box 310 is provided with a first flow channel 311, both ends of which are connected to the second glue box 320. The sidewalls of the first flow channel 311 are provided with multiple glue outlets 315, which face the glue storage position. Consumed glue is replenished by pouring glue into the second glue box 320. The glue is then transported from the second glue box 320 to the first glue box 310, flows through the first flow channel 311, and then flows out of the glue outlets 315.

[0032] It is understandable that, referring to Figure 1 and Figure 3 The first glue box 310 is provided with a second flow channel 312. The second flow channel 312 is arranged in a vertical direction and is connected to the second glue box 320. The second flow channel 312 is also connected to the first flow channel 311. A baffle is provided between the second flow channel 312 and the first flow channel 311. The second flow channel 312 is provided to allow excess glue in the first flow channel 311 to flow back into the second glue box 320 through the second flow channel 312. The baffle is provided between the first flow channel 311 and the second flow channel 312. When the glue in the first flow channel 311 increases, the glue flows over the baffle and enters the second flow channel 312. This prevents the glue in the first flow channel 311 from being diverted by the second flow channel 312, thereby ensuring the glue quantity in the first flow channel 311.

[0033] It is understandable that, referring to Figures 1 to 3 Third flow channels 313 are defined on the symmetrical sidewalls of the first glue box 310. These channels are located at either end of the glue roller 330. One end of the third flow channel 313 corresponds to the glue storage area, while the other end communicates with the second glue box 320. The inlet of the third flow channel 313 is located above the glue roller 330 and the glue coating roller 340. As the glue in the glue storage area accumulates and the glue level exceeds the inlet of the third flow channel 313, it flows into the third flow channel 313 and then back into the second glue box 320. This prevents glue overflow and saves costs.

[0034] It is understandable that, referring to Figure 1 and Figure 3 A glue pump assembly is disposed within the second glue box 320. A first delivery channel 321 is defined in the sidewall of the second glue box 320. The first delivery channel 321 is vertically disposed, and the glue pump assembly delivers glue to the first flow channel 311 through the first delivery channel 321. The glue pump assembly actively delivers glue from bottom to top along the first delivery channel 321, filling the first delivery channel 321 with glue, thereby increasing the glue delivery flow rate and improving delivery efficiency.

[0035] It is understandable that, referring to Figure 1 and Figure 3 The glue pump assembly includes a motor and two meshing gears 323. The motor drives the two gears 323 to rotate. A second delivery channel 322 is defined on the bottom wall of the second glue box 320. The two gears 323 mesh within the second delivery channel 322, which communicates with the first delivery channel 321. The motor drives the two gears 323 to rotate, and the teeth of the two gears 323 move the glue, driving the glue from the second delivery channel 322 to the first delivery channel 321. This achieves rapid glue delivery and a simple and stable structure.

[0036] It is understandable that, referring to Figure 1 and Figure 2 A pressing paper plate 370 is provided on the lower side of the first glue box 310. When the booklet is glued, when the glue roller 330 presses down on the booklet, the end of the booklet away from the glue roller 330 will tilt up, causing the booklet to deviate. When glue is rolled, the pressing paper plate 370 presses down the booklet to prevent the booklet from tilting up and improve the stability of glue rolling.

[0037] It is understandable that, referring to Figure 2 The first glue box 310 is provided with a glue receiving plate 316, which is arranged below the glue coating roller 340. The glue receiving plate 316 receives the glue dripping from the glue coating roller 340 to prevent the glue from dripping directly onto the book and avoiding contamination of the book.

[0038] It is understandable that, referring to Figure 1 and Figure 2 The first glue box 310 can be provided with a plurality of scraping members 350, and the plurality of scraping members 350 are arranged along the axial direction of the glue coating roller 340. The scraping member 350 is provided with an arc surface matching the glue coating roller 340 at one end facing the glue coating roller 340, and a gap is formed between the arc surface and the glue coating roller 340. When the glue coating roller 340 rotates, if the thickness of the surface glue is greater than the gap, the excess part will be scraped away by the scraping member 350, thereby evenly controlling the thickness of the glue on the surface of the glue coating roller 340, so that the glue transferred to the surface of the rolling glue roller 330 remains stable.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
