Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology in paper box production, and specifically to an automatic adhesive coating device for paper box edges. Background Technology

[0002] A cardboard box is a three-dimensional shape, which is composed of a number of facets that are moved, stacked, folded and surrounded. The facets in the body play a role in dividing space. In the cardboard box production process, in order to make the cardboard box form a whole, glue needs to be applied to the edges of the cardboard box. After applying glue, it is easy to connect two facets. Glue application equipment is used when applying glue.

[0003] Traditional cardboard box gluing equipment often results in glue tips and tails at both ends of the cardboard box after gluing. Excess glue can affect the subsequent adhesion of the cardboard box. To address this, we propose an automatic gluing device for cardboard box edges. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses an automatic glue application device for paper box edges, comprising:

[0031] Workbench 1, with a paper box conveying roller 2 installed on one side of the top of the workbench 1 for continuously conveying the paper boxes to be coated with glue, and a glue coating pad 3 symmetrically distributed with the paper box conveying roller 2 installed on the other side of the top of the workbench 1 for supporting the glue coating part of the paper box.

[0032] The glue scraping mechanism 5 includes a bracket 504 fixedly connected to the outside of the workbench 1. A cleaning plate 509 for cleaning residual glue on the scraper 501 is fixedly connected to the other side of the bracket 504. A drive motor 502 is provided above the workbench 1. A transmission rod 506 is fixedly connected to the drive motor 502 through an output shaft. An installation rod 511 is provided on the outside of the transmission rod 506. A scraper 501 for scraping off excess glue at the glue head and tail of the paper box is fixedly connected to the other end of the installation rod 511.

[0033] Specifically, a motor frame 503 is fixedly connected to the outside of the drive motor 502. The motor frame 503 is fixedly connected to the outside of the bracket 504, providing stable support for the drive motor 502.

[0034] Specifically, a mounting sleeve 508 is fixedly connected to the outside of the transmission rod 506, and an internal threaded cylinder 507 is fixedly connected to the outside of the mounting sleeve 508. The mounting rod 511 is threadedly connected to the inside of the internal threaded cylinder 507. This structure allows for convenient adjustment of the radial position and angle of the mounting rod 511 on the transmission rod 506, thereby adjusting the position and glue application angle of the scraper 501 relative to the cardboard box to adapt to cardboard boxes of different sizes or glue application requirements.

[0035] Specifically, a collection box 505 is provided on the outer side of the bracket 504. Two symmetrically distributed limiting blocks 510 are fixedly connected to the bottom of the collection box 505. The opposing surfaces of the two limiting blocks 510 are in contact with the outer side of the bracket 504 for positioning and detachable installation of the collection box 505. During the scraping process of the scraper 501, when the scraper 501 passes the cleaning plate 509, the cleaning plate 509 will scrape off the residual adhesive on the outside of the scraper 501. The residual adhesive scraped off by the cleaning plate 509 falls into the collection box 505 below under the action of gravity, which facilitates the periodic removal and cleaning of the accumulated adhesive residue inside, keeps the working environment clean and reduces waste.

[0036] Example 2:

[0037] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0038] The glue coating mechanism 4 includes a glue storage tank 403 set above the workbench 1. One end of the transmission rod 506 extends into the glue storage tank 403, and the outside is equipped with equally spaced stirring rods 407. When the transmission rod 506 rotates, it synchronously drives the stirring rods 407 to continuously stir the glue liquid in the glue storage tank 403 to prevent the glue liquid from settling or thickening, and to ensure the uniformity and fluidity of the glue liquid. A glue coating cylinder 401 is set above the glue coating pad 3. The glue outlet at the bottom of the glue coating cylinder 401 is rotatably connected to a glue coating roller 405 for uniformly coating the glue liquid onto the designated edge position of the paper box.

[0039] Specifically, a pump body 402 extending into the interior of the glue storage tank 403 is provided on the outside of the glue storage tank 403. The glue outlet of the pump body 402 is fixedly connected to a delivery pipe 406, which is used to pump out the stirred glue liquid in the glue storage tank 403 in a metered manner when the glue application process is started.

[0040] Specifically, the other end of the delivery pipe 406 is connected to the inside of the coating cylinder 401, which delivers the adhesive pumped out by the pump body 402 into the coating cylinder 401. The coating cylinder 401 is cone-shaped, which facilitates the adhesive to flow smoothly to the coating roller 405 at the bottom by gravity.

[0041] Specifically, a support plate 404 is fixedly connected to the top of the workbench 1, and a glue storage tank 403 is fixedly connected to the outside of the support plate 404, providing a stable installation base for the glue storage tank 403.

[0042] When the carton conveyor roller 2 transports the carton to a position above the glue-coating pad 3 and directly below the glue-coating roller 405, the pump 402 starts, drawing the glue solution stirred by the stirring rod 407 from the glue storage tank 403 and pumping it into the conical glue-coating cylinder 401 through the conveying pipe 406. The glue solution flows to the bottom of the glue-coating cylinder 401, wetting and driving the glue-coating roller 405 to rotate. The glue-coating roller 405 then contacts the moving edge of the carton, uniformly and quantitatively coating the carton with glue at the designated location.

[0043] The remaining structure is the same as that in Example 1.

[0044] The workflow of this utility model is as follows:

[0045] When applying glue to the cardboard box, the cardboard box conveying roller 2 conveys the cardboard box that needs to be glued. When the cardboard box moves to the bottom of the glue application roller 405, the pump body 402 draws the glue liquid from the glue storage tank 403 into the conveying pipe 406, and then into the glue application cylinder 401 through the conveying pipe 406. Finally, the glue application roller 405 applies glue to the part (edge) of the cardboard box to be glued.

[0046] After being coated with glue by the glue-coating roller 405, the cardboard box is continued to be conveyed by the cardboard box conveying roller 2. When the glue head of the cardboard box moves below the scraper 501, the drive motor 502 drives the transmission rod 506 to rotate through the output shaft. The rotation of the transmission rod 506 drives the scraper 501 to rotate. When the scraper 501 rotates, it can scrape off the glue head and glue tail of the cardboard box respectively.

[0047] When the scraper 501 rotates, the glue residue on its exterior can be scraped off by the cleaning plate 509 and fall into the collection box 505 below under the action of gravity. The collection box 505 is removed periodically to clean the glue residue inside.

[0048] In addition, the rotation of the transmission rod 506 drives the stirring rod 407 inside the glue storage tank 403 to rotate, and the rotation of the stirring rod 407 agitates the glue liquid inside the glue storage tank 403.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
