Description

Technical Field

[0001] This utility model relates to the field of book cover adhesive coating technology, and in particular to a book cover adhesive coating device. Background Technology

[0002] The book cover is the outermost layer of a book or other publication. It usually contains the book title, author, publisher's name, and decorative patterns or images, and is part of the book's binding design. To protect the book cover, a protective film is typically applied during production to ensure its quality and aesthetic appeal.

[0003] However, traditional coating equipment mostly uses simple roller coating or nozzle spraying methods. These methods often struggle to achieve optimal coating when dealing with covers of different materials and thicknesses, resulting in uneven glue distribution. These technical problems not only affect the protective effect of book covers but also increase the difficulty and cost of subsequent processing, reducing production efficiency. Utility Model Content

[0004] Based on this, the present invention provides a book cover glue coating device with a simple structure and convenient use. By using the adjustment mechanism of the arc-shaped slot, the glue coating angle can be changed by simply adjusting the position of the bolts to meet the leveling requirements of high viscosity glue. Furthermore, by cooperating with the moving gantry and the linear module, the glue applicator and the glue roller can move synchronously, ensuring the timing of glue spraying and rolling processes and greatly improving the uniformity of coating.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0006] A book cover adhesive coating device, comprising:

[0007] The glue-spreading roller assembly includes a material loading platform, linear modules mounted on opposite sides of the material loading platform, a moving gantry connecting the two linear modules, bushings slidably connected to the bottom ends of the inner walls on opposite sides of the moving gantry, a glue-spreading roller rotatably connected to the two bushings, and lifting cylinders respectively mounted on the top ends of the inner walls on opposite sides of the moving gantry; the lifting cylinders are downwardly connected to the bushings; and

[0008] A coating assembly is installed on one side of the glue-spreading roller assembly. The coating assembly includes a bracket connected to the top of the movable gantry, corner brackets connected to opposite ends of the bracket, and a glue applicator connected between the two corner brackets. The corner brackets have multiple evenly spaced arc-shaped slots on one end for connecting the glue applicator. The opposite ends of the glue applicator have assembly holes, which correspond to the arc-shaped slots. Bolts are used to pass through the arc-shaped slots and connect to the inside of the assembly holes to achieve the assembly of the glue applicator and the corner brackets.

[0009] The aforementioned book cover glue coating device has a simple structure and is easy to use. By adjusting the arc-shaped slot adjustment mechanism, the glue coating angle can be changed by simply adjusting the bolt position to meet the leveling requirements of high-viscosity glue. Furthermore, by cooperating with the moving gantry and the linear module, the glue applicator and the glue roller can move synchronously, ensuring the timing of glue spraying and rolling processes and greatly improving the uniformity of coating.

[0010] In one embodiment, the number of arc-shaped slots is four, and the number of assembly holes is two.

[0011] In one embodiment, the length direction of the applicator is aligned with the axis of the glue-spreading roller.

[0012] In one embodiment, the glue applicator has a plurality of glue spray holes evenly spaced along the length of the glue applicator on the side facing the material loading platform.

[0013] In one embodiment, the spacing between adjacent spray nozzles is 10-18 mm.

[0014] In one embodiment, the movement direction of the bushing is perpendicular to the material loading platform; the movement direction of the lifting cylinder is perpendicular to the material loading platform.

[0015] In one embodiment, the distance between the spreading roller and the material loading platform is adjustable from 3 to 15 mm. Attached Figure Description

[0027] Please see Figures 1 to 5 The present invention provides a book cover adhesive coating device, which includes a glue-spreading roller assembly 10 and a coating assembly 20 installed on one side of the glue-spreading roller assembly 10.

[0028] The glue-coating roller assembly 10 includes a material-carrying platform 11, linear modules 12 mounted on opposite sides of the material-carrying platform 11, a movable gantry 13 connecting the two linear modules 12, bushings 14 slidably connected to the bottom ends of the inner walls on opposite sides of the movable gantry 13, a glue-coating roller 15 rotatably connected to the two bushings 14, and lifting cylinders 16 respectively mounted on the top ends of the inner walls on opposite sides of the movable gantry 13. The material-carrying platform 11 is used to support the book cover to be coated, and the glue-coating roller 15 is used to evenly coat the glue onto the surface of the book cover.

[0029] Specifically, such as Figure 2 As shown, the lifting cylinder is connected downward to the bushing 14 to drive the bearing 14 to slide, thereby adjusting the distance between the glue-spreading roller 15 and the material-carrying platform 11 to accommodate book covers of different thicknesses. Furthermore, the distance between the glue-spreading roller 15 and the material-carrying platform 11 can be adjusted from 3 to 15 mm.

[0030] In this embodiment, the movement direction of the bushing 14 is perpendicular to the material loading platform 11; the movement direction of the lifting cylinder 16 is perpendicular to the material loading platform 11.

[0031] The coating assembly 20 includes a bracket 21 connected to the top of the movable gantry 13, corner brackets 22 connected to opposite ends of the bracket 21, and an applicator 23 connected between the two corner brackets 22. The length direction of the applicator 23 is consistent with the axis of the glue-spreading roller 15. On the side of the applicator 23 facing the material platform 11, a plurality of glue spray holes 230 are evenly spaced along the length direction of the applicator 23. The spacing between adjacent glue spray holes 230 is 10-18mm, and glue can be sprayed onto the surface of the book cover through the glue spray holes 230.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the corner bracket 22 is provided with a plurality of arc-shaped slots 220 evenly spaced on one end of the glue applicator 23. The two opposite end faces of the glue applicator 23 are respectively provided with assembly holes (not shown in the figure). The assembly holes correspond to the arc-shaped slots 220. After the bolts are inserted through the arc-shaped slots 220, they are connected to the inside of the assembly holes, so that the glue applicator 23 and the corner bracket 22 can be assembled.

[0033] In this embodiment, there are four arc-shaped slots 220 and two assembly holes. In actual use, by selecting different arc-shaped slots 220 or adjusting the installation position of the bolts within the arc-shaped slots 220, the tilt angle of the applicator 23 can be easily changed to meet different adhesive application requirements.

[0034] Furthermore, such as Figure 4 and Figure 5 As shown, one end of the glue applicator 23 is connected to a glue feeder (not shown) via a glue tube 24 to supply glue to the glue applicator 23.

[0035] The aforementioned book cover glue coating device has a simple structure and is easy to use. By adjusting the arc-shaped slot 220, the glue coating angle can be changed by simply adjusting the bolt position to meet the leveling requirements of high-viscosity glue. Furthermore, by cooperating with the moving gantry 13 and the linear module 12, the glue applicator 23 and the glue roller 15 can move synchronously, ensuring the timing of glue spraying and rolling processes and greatly improving the uniformity of coating.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
