Description

Technical Field

[0001] This utility model belongs to the field of paper tube production technology and relates to a gluing device for paper tube production. Background Technology

[0002] Paper tubes are tubes made of rolled paper, frequently used for packaging and widely applied in various fields. During paper tube production, the paper needs to be coated with glue. Currently, the glue is typically applied from top to bottom during paper transport, allowing a large amount of glue to flow over the paper, after which excess glue is scraped off. However, since the paper is usually transported horizontally, the glue on the top of the paper is much more abundant than on the bottom, resulting in uneven coating. Furthermore, this method of application leads to the paper absorbing more glue, causing waste and increasing the subsequent drying time. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a gluing device for paper tube production. This device solves the problems of uneven gluing caused by more glue on the top of the paper than on the bottom, and the waste caused by excessive glue absorption by the paper due to the pouring method, which increases the subsequent drying time of the paper tube.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A gluing device for paper tube production, characterized in that it includes a glue tank, a support frame is fixedly connected in the middle of the glue tank, a plurality of glue spraying components are equidistantly arranged on the support frame, each glue spraying component includes two air vents, the two air vents are fixedly connected to the support frame, a plurality of mutually symmetrical nozzles are connected to the two air vents, and a glue delivery pipe connected to the air vents is provided on the support frame.

[0006] In the above-mentioned glue coating device for paper tube production, a scraper corresponding to the nozzle is provided on the upper right side of the glue tank.

[0007] In the above-mentioned glue coating device for paper tube production, several grooves corresponding to the glue spraying components are provided on the upper left side of the glue tank, and two guide rollers are rotatably connected in the grooves.

[0008] In the above-mentioned glue coating device for paper tube production, the nozzle is inclined downwards.

[0009] In the above-mentioned glue coating device for paper tube production, a stirring shaft is rotatably connected inside the glue tank, a stirring auger is provided on the stirring shaft, and a drive motor that drives the stirring shaft to rotate is provided on the glue tank.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] By spraying glue onto both sides of the paper through the nozzle, the glue can be applied evenly to both sides of the paper, and the appropriate amount of glue can be controlled to avoid glue waste and reduce the subsequent drying time of the paper tube. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 As shown,

[0017] A glue coating device for paper tube production, characterized in that it includes a glue tank 2, a support frame 3 fixedly connected in the middle of the glue tank 2, a plurality of glue spraying components equidistantly arranged on the support frame 3, each glue spraying component including two venting plates 4, the two venting plates 4 being fixedly connected to the support frame 3, a plurality of mutually symmetrical nozzles 5 being connected to the two venting plates 4, and a glue delivery pipe 6 connected to the venting plates 4 being provided on the support frame 3.

[0018] In this embodiment, the paper to be coated with glue is conveyed vertically, passing through the nozzle 5 between the two ventilation plates 4. The glue delivery pipe 6 delivers the glue from the glue tank 2 to the ventilation plates 4. The glue in the ventilation plates 4 is then sprayed from the nozzle 5 onto both sides of the paper. The glue that is not sprayed onto the paper falls back into the glue tank 2 for reuse. The paper coated with glue is then rolled into a paper tube. By spraying glue onto both sides of the paper through the nozzle 5, the glue is evenly applied to both sides of the paper, and the appropriate amount of glue can be controlled to avoid glue waste and reduce the subsequent drying time of the paper tube.

[0019] In this embodiment, a scraper 7 corresponding to the nozzle 5 is provided on the upper right side of the glue tank 2. Before the paper tube is wound, the scraper 7 scrapes off excess glue from the paper tube.

[0020] In this embodiment, the glue tank 2 has several grooves 8 on its upper left side corresponding to the glue spraying assembly, and two guide rollers 9 are rotatably connected within the grooves 8. The rotatable connection of the guide rollers 9 ensures that the paper tube remains taut during transport.

[0021] In this embodiment, the nozzle 5 is tilted downwards. The downward tilt of the nozzle 5 facilitates the discharge of excess glue into the glue tank 2.

[0022] In this embodiment, a stirring shaft 10 is rotatably connected inside the glue tank 2, and a stirring auger 11 is mounted on the stirring shaft 10. A drive motor 12 is mounted on the glue tank 2 to drive the stirring shaft 10 to rotate. By driving the stirring shaft 10 and the stirring auger 11 to rotate through the drive motor 12, the glue maintains good fluidity.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0024] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
