Description

Technical Field

[0001] The utility model relates to the technical field of boxboard paper gluing process, in particular to a boxboard paper gluing device. Background Art

[0002] The main purpose of sizing cardboard is to improve the surface strength, control the penetration of water and ink, and prevent hair loss and powder loss during printing. The sizing process usually uses two rollers to squeeze the glue to make the paper adhere to the glue to complete the sizing process.

[0003] Conventionally, when the rotation speed of the glue roller is relatively fast, the glue liquid is likely to cause glue throwing on both sides of the glue roller, causing excessive glue liquid to adhere to the paper surface near the two ends of the glue roller, and the paper is likely to break and roll during the paper rolling process, thereby producing unqualified paper, increasing the product unqualified rate, and affecting the quality of paper. Therefore, someone has proposed a boxboard paper gluing device, such as a boxboard paper gluing device with a publication number of CN217289037U, comprising a support frame, a glue roller with an end rotatably arranged on the support frame, and a paper roller; the length direction of the paper roller and the glue roller is The paper roller and the glue roller rod are parallel, and the roller surfaces close to each other are used to abut the paper surface at the same time; it also includes two side baffles fixed on the support frame, and the two side baffles are located on both sides of the length direction of the glue roller rod; one end of the side baffle is close to the rotating shaft of the glue roller rod, and the end of the side baffle away from the rotating shaft of the glue roller rod extends to the outside of the glue application surface away from the glue roller rod; it also includes two positive baffles, and the two positive baffles are located on the outside of the glue application surface of the glue roller rod, and the ends of the positive baffles are fixed to the side baffles, and there is a gap between the positive baffles and the glue application surface of the glue roller rod to accommodate the glue liquid. By setting the side baffles, the side baffles block the glue liquid thrown out from the two ends of the glue roller rod, thereby reducing the phenomenon of paper breaking and paper rolling during the paper rolling process, reducing the product unqualified rate, and ensuring the quality of paper;

[0004] However, during use, the device is provided with a scraper, which scrapes off excess glue to ensure an appropriate amount of glue on the glue roller. At the same time, the scraper can also level the glue on the glue roller to make the glue on the paper surface more evenly spread. However, the scraper is arranged in a straight strip shape, which easily causes the glue to gather at both ends when scraping the glue, resulting in excessive glue at both ends of the glue roller, affecting the use of glue, and making it inconvenient to use.

[0025] Example 1

[0026] See also Figure 1 , Figure 2 and Figure 3 A boxboard gluing device shown in the figure includes a workbench 1, and also includes a support frame 5 fixedly installed on both sides of the surface of the workbench 1, a glue roller rod 9 is fixedly installed on the top inner side of the support frame 5, a side plate body 11 is fixedly installed on one side of the glue roller rod 9 installed on the top of the support frame 5, a rotating drum 10 is fixedly installed on the inner side of the side plate body 11, one end of the rotating drum 10 is fixedly connected to a servo motor 8, and scrapers 17 are fixedly installed around the surface of the rotating drum 10, and the scrapers 17 are arranged to be S-shaped, and the scrapers 17 are arranged in a plurality of groups.

[0027] It should be noted that: in this solution, a glue roller rod 9 is installed on the top of the inner side of the support frame 5, and a rotating drum 10 is connected to the glue roller rod 9 at a lower position on one side through two groups of side plates 11 and a servo motor 8. A plurality of groups of S-shaped scrapers 17 are arranged on the outer side of the rotating drum 10, which can facilitate the rotation of the rotating drum 10, thereby cooperating with the S-shaped scraper 17 to scrape the outer side of the glue roller rod 9 and evenly distribute the glue on the outer side of the glue roller rod 9 for gluing.

[0028] Among them, see Figure 1 , Figure 2 and Figure 3 In the figure, an inclined plate 12 is installed under the rotating drum 10, and the inclined plate 12 is fixedly installed on the inner side of the glue storage tank 7, and the glue storage tank 7 is fixedly installed under the side plate 11.

[0029] It should be noted that the inclined plate 12 is installed under the rotating drum 10, and the inclined plate 12 is installed on the inner side of the glue storage tank 7 in an inclined shape, so that the excess glue scraped by the scraper 17 can be discharged into the glue storage tank 7 through the inclined plate 12 for storage, so as to facilitate the recycling of the glue.

[0030] It is worth noting that during use, the glue roller rod 9 rotates to apply glue to the surface of the boxboard paper. The surface of the drum 10 is provided with an S-shaped scraper 17 to scrape the glue on the surface of the glue roller rod 9 while guiding and evenly distributing the scraped excess glue on the surface of the glue roller rod 9, thereby facilitating the glue roller rod 9 to apply glue to the boxboard paper. The spacing between the scraper 17 and the glue roller rod 9 can facilitate guiding the excess glue downward to the surface of the inclined plate 12, thereby guiding the excess glue into the glue storage tank 7, thereby facilitating the storage of the excess glue and facilitating the recycling of the glue. When the glue roller rod 9 rotates counterclockwise, the drum 10 rotates clockwise, thereby scraping the glue upward and conveying it to the surface of the inclined plate 12 and into the glue storage tank 7 through the scraper 17. The servo motor 8 drives the drum 10 to slow down its rotation speed, so that the glue will not be thrown out, and the glue will flow to the surface of the inclined plate 12 after the scraper 17 drives the glue to rotate.

[0031] Example 2

[0032] See also Figure 1 , Figure 2 and Figure 3 This embodiment further explains Example 1. A paper roller 13 is installed below the glue roller rod 9 in the figure. One end of the paper roller 13 is fixedly connected to the top power output end of the transmission motor 15 through a transmission shaft 16. A screw block 14 is fixedly installed at the bottom end of the transmission motor 15 and the other end of the paper roller 13. The screw block 14 is slidably connected to the sliding rail 6.

[0033] It should be noted that: the designed glue roller rod 9 is equipped with a paper roller 13 under it and a transmission shaft 16 is inserted into the center of the paper roller 13, one end of the transmission shaft 16 is connected to the transmission motor 15, and a screw block 14 is connected to the bottom end of the transmission motor 15 and the other end of the transmission shaft 16. The screw block 14 is slidably connected to the sliding rail 6, and the screw block 14 can slide up and down in the sliding rail 6 to drive the paper roller 13 to slide up and down, thereby adjusting the distance between the paper roller 13 and the glue roller rod 9, so as to facilitate the clamping and gluing of boxboard paper of different thicknesses.

[0034] Also, see Figure 1 , Figure 2 and Figure 3 The sliding rail 6 shown in the figure is opened at the middle end of the bottom of the support frame 5, and a synchronous servo motor 2 is fixedly installed at the bottom end of the sliding rail 6. The top power output end of the synchronous servo motor 2 is fixedly connected to the bottom power input end of the threaded rod 4, and the surface of the threaded rod 4 is threadedly connected with the screw block 14.

[0035] It should be noted that: the designed sliding rail 6 is opened at the middle end position of the bottom of the support frame 5, and a synchronous servo motor 2 is installed at the bottom of the sliding rail 6 and connected to the threaded rod 4, and the surface of the threaded rod 4 is threadedly connected to the screw block 14, which can facilitate the synchronous servo motor 2 to drive the two groups of threaded rods 4 to rotate synchronously, so that the screw block 14 can slide up and down synchronously with the rotation of the threaded rod 4 in the sliding rail 6 under the restriction of the sliding rail 6, thereby driving the paper roller 13 to slide up and down to adjust the distance between it and the glue roller rod 9.

[0036] It is worth noting that: during use, the synchronous servo motor 2 is started according to the thickness of the boxboard paper that needs to be glued. The synchronous servo motor 2 starts to drive the two groups of threaded rods 4 to rotate synchronously, so that the screw block 14 threadedly connected to the surface of the threaded rod 4 is received under the restriction of the sliding rail 6, so that the screw block 14 slides up and down in the sliding rail 6, thereby driving the distance between the paper roller 13 and the glue roller rod 9, so as to clamp and glue the boxboard paper of different thicknesses.

[0037] Example 3

[0038] See also Figure 1 , Figure 2 and Figure 3 This embodiment further illustrates other embodiments. The top end of the screw block 14 in the figure is fixedly connected to the limit plate 3. The glue storage tank 7 is opened in a U shape and the inclined plate 12 is installed on the inner side. The inclined plate 12 is inclined upward near one end of the glue roller rod 9. The sliding rail 6 is opened in an inclined shape and is consistent with the inclination between the glue roller rod 9 and the paper roller 13.

[0039] It should be noted that: a limit plate 3 is installed on the top of the designed screw block 14, and the size of the limit plate 3 is larger than the size of the sliding rail 6, which can provide protection and restriction on the outside of the screw block 14. The designed glue storage tank 7 is U-shaped and an inclined plate 12 is installed on the inside. The inclined plate 12 is tilted upward near the end of the glue roller rod 9, so that the excess glue scraped off the surface of the glue roller rod 9 can be guided to the glue storage tank 7 through the inclined plate 12 for recycling. The designed sliding rail 6 is inclined and keeps the same inclination as the glue roller rod 9 and the paper roller 13, which can facilitate the adjustment of the distance between the paper roller 13 and the glue roller rod 9.

[0040] It is worth noting that: in order to facilitate the scraping of the surface of the glue roller rod 9, the distance between the scraper 17 and the glue roller rod 9 is small. At the same time, the glue roller rod 9 will rotate counterclockwise when in use, while the rotating drum 10 equipped with the scraper 17 will rotate clockwise, which can scrape the glue and slowly rotate upwards and guide it to the surface of the inclined plate 12 to flow into the glue storage tank 7 for storage and recycling.
