Description

Technical Field

[0001] This utility model relates to the technical field of notebook production equipment, and in particular to a cold glue backing machine that provides uniform glue application. Background Technology

[0002] There are generally two ways to bind exercise books: one is to sew the cover and the inner pages together, leaving the stitching exposed; the other is to bind the cover and the inner pages together with cold glue.

[0003] To improve the automation and production efficiency of cold glue binding, I previously applied for a Chinese utility model patent with patent number CN202220545117.8, entitled "A Cold Glue Backing Production Line for Sheet-to-Sheet Workbooks." In practical application, I found that the cold glue backing machine uses three sets of gluing devices to apply glue to the back edges of each stacked inner page and cover. During the gluing process, because the back edges of the inner pages and cover are milled and roughened, the amount of glue absorbed by the inner pages varies at different locations. When the amount of glue provided to the same location is constant, it leads to uneven and non-linear glue adhesion on the cover. If this area is not subsequently covered by a paper strip, the appearance of the workbook will be poor, requiring improvement. Utility Model Content

[0056] Detailed implementation plan: See below Figures 1-8 This utility model is a cold glue backing machine for uniform glue application.

[0057] The machine includes a frame 1, on which a first pushing mechanism 2 and a second pushing mechanism 11 are provided. The first pushing mechanism 2 is used to transport notebooks to be bound, which include stacked inner pages and a top cover and a bottom cover placed on the top and bottom sides of the inner pages, respectively. The second pushing mechanism 11 is used to receive the notebooks to be bound from the first pushing mechanism 2 and continue to transport them forward. The portion of the frame 1 corresponding to the second pushing mechanism 11 is provided sequentially from upstream to downstream as follows:

[0058] The paper suction device 3 is used to suction the end of the top cover upwards and the end of the bottom cover downwards, and to detach the ends of both the top cover and the bottom cover from the inner pages.

[0059] Paper separating device 4 is used to cooperate with the continued forward conveying of the top cover and bottom cover after the inner pages are separated at the ends;

[0060] The first gluing device 5 is installed on one side of the paper separating device 4 and is used to apply glue to the upper and lower covers at their ends.

[0061] Several second gluing devices 6, spaced apart from each other along the conveying direction of the second pushing mechanism 11, are used to apply adhesive to the inner pages, as well as to the ends of the top and bottom covers that are repositioned on the upper and lower sides of the inner pages.

[0062] As a preferred embodiment of this example, please refer to Figure 6 As can be seen, the paper suction device 3 includes:

[0063] Mounting bracket 31 is fixed on frame 1;

[0064] The first cylinder 32 is mounted on the mounting bracket 31 and is used to drive the lower suction nozzle 33 to rise and fall.

[0065] The second cylinder 34 is mounted on the mounting bracket 31 and is used to drive the upper suction nozzle 35 to rise and fall. The upper suction nozzle 35 is positioned directly above the lower suction nozzle 33.

[0066] The working principle of the paper suction device 3 is as follows: First, based on the thickness of the notebook, the initial positions of the upper suction nozzle 35 and the lower suction nozzle 33 are adjusted by driving the lower suction nozzle 33 to rise and fall using the first cylinder 32 and the upper suction nozzle 35 to rise and fall using the second cylinder 34. When the notebook to be bound is conveyed to the paper suction device 3 via the second conveying mechanism, the lower suction nozzle 33 absorbs the end of the bottom cover and the upper suction nozzle 35 absorbs the end of the top cover. The first cylinder 32 drives the lower suction nozzle 33 to rise and the second cylinder 34 drives the upper suction nozzle 35 to fall, thereby detaching the ends of the bottom cover and the top cover from the inner pages. Note that at this time, the inner pages, the top cover, and the bottom cover are all conveyed forward normally.

[0067] Next, please continue reading. Figure 6 As can be seen in this embodiment, a brush holder is fixed on the mounting bracket 31, and brush bristles are installed on the brush holder. The brush bristles are used to clean the dust located at the ends of the inner pages, the upper cover and the lower cover.

[0068] Then, please see Figure 7 and Figure 8 As can be seen, the paper separating device 4 includes:

[0069] The first fixed seat 41 is fixed on the frame 1;

[0070] The first connecting bar 42 is fixed on the first fixing seat 41;

[0071] The lower paper separating assembly 43 is installed on the first connecting strip 42. The lower paper separating assembly 43 includes first paper separating plates 431 arranged vertically and vertically, and a first channel for the bottom cover to pass through is formed between the two first paper separating plates 431.

[0072] The second mounting base 44 is fixed on the frame 1;

[0073] The second connecting bar 45 is fixed to the second fixing seat 44;

[0074] The upper paper separating assembly 46 is mounted on the second connecting strip 45. The upper paper separating assembly 46 includes two second paper separating plates 461 arranged vertically and vertically, and a second channel is formed between the two second paper separating plates 461 for the upper cover to pass through.

[0075] Furthermore, in this embodiment, one end of each of the two first dividing plates 431 expands outward to the upper and lower sides respectively, forming a first inlet 433, and one end of each of the two second dividing plates 461 expands outward to the upper and lower sides respectively, forming a second inlet 463. A first pad is provided between the two first dividing plates 431, and a second pad 462 is provided between the two second dividing plates 461.

[0076] The working principle of the paper separating device 4: When the inner pages, top cover and bottom cover that have been separated at the ends are conveyed to the paper separating device 4 via the second conveying mechanism, the end of the bottom cover enters the first channel through the first inlet 433, and the end of the top cover enters the second channel through the second inlet 463, thereby ensuring that the ends of the top cover and bottom cover are separated from the inner pages in the paper separating device 4.

[0077] Next, please refer to Figure 4 and Figure 5 As can be seen, the first gluing device 5 includes:

[0078] Mounting plate 51 is fixed on frame 1;

[0079] At least one fixed shaft seat 52 is fixed on the mounting plate 51. A first shaft 53 is passed through the fixed shaft seat 52. The lower end of the first shaft 53 is linked to the main drive source. A drive gear 54 is fixed on the first shaft 53.

[0080] The second shaft 56 has a driven gear 55 fixed on it, and the driven gear 55 meshes with the driving gear 54.

[0081] The support frame is fixed on the mounting plate 51 or the fixed bearing 52. The first shaft 53 and the second shaft 56 are both mounted on the support frame through several bearings.

[0082] Rubber wheel 57 is fixed to the upper end of the second shaft 56;

[0083] The glue box 510 is mounted on the support frame, and the glue wheels 57 are arranged inside the glue box 510.

[0084] Then, in this embodiment, the first adhesive applicator 5 further includes:

[0085] A centering sleeve 58 is fitted onto a rubber wheel 57. The centering sleeve 58 is provided with a support block 581 that engages with or is fixed to the frame 1.

[0086] The scraping assembly 59 includes a fixing block 594 fixed to one side of the centering sleeve 58, a scraper seat 591 slidably disposed on the fixing block 594, and a scraper 592 fixed on the scraper seat 591. The scraper seat 591 is provided with an adjusting member 593 for adjusting the relative position of the fixing block 594 and the scraper seat 591.

[0087] The working principle of the first gluing device 5: The glue supply equipment injects cold glue into the glue tank 510 through the conduit. The first shaft 53 is driven to rotate by the main drive source, which in turn drives the drive gear 54 fixed on the first shaft 53 to rotate. Since the driven gear 55 fixed on the second shaft 56 meshes with the drive gear 54, it drives the second shaft 56 and the glue wheel 57 fixed on the second shaft 56 to rotate. The design of the centering sleeve 58 is to increase the rotational stability of the glue wheel 57 and to provide a place for the glue scraping assembly 59 to be installed. Regarding the glue scraping assembly 59, the relative position of the fixing block 594 and the scraper seat 591 can be adjusted by adjusting the adjusting part 593, thereby adjusting the scraping amplitude of the scraper blade 592 fixed on the scraper seat 591 on the glue wheel 57. The design of the scraper blade 592 can precisely control the amount of glue and adjust the uniformity of the glue layer to ensure that the glue adheres efficiently and evenly to the ends of the upper and lower cover surfaces.

[0088] Since the first gluing device 5 is arranged on one side of the paper separating mechanism, during the process of conveying the end of the bottom cover along the first channel and the end of the top cover along the second channel, the first gluing device 5 can apply side glue to the ends of the top cover and the bottom cover separately, and ensure that the side glue is uniform and straight.

[0089] After the first gluing device 5 completes the individual top and bottom covers with glue, the top and bottom covers are conveyed forward by the second conveying mechanism and leave the paper separating device 4. Then, the top and bottom covers fall back onto the inner pages and are conveyed forward together with the inner pages. The three second gluing devices 6 work together to apply back glue to the inner pages, as well as to the ends of the top and bottom covers that have been repositioned on the top and bottom sides of the inner pages. Since the working principle of the second gluing devices 6 is the same as that of the first gluing device 5, it will not be described in detail here.

[0090] More specifically, the portion of the frame 1 corresponding to the second feeding mechanism 11 is further provided with:

[0091] The drying mechanism 7 is arranged downstream of the second gluing device and is used to dry the side adhesive and back adhesive on the notebook.

[0092] The third gluing device 8 is located downstream of the drying mechanism 7 and is used to apply glue to the spine of the book again.

[0093] The spine-covering mechanism is used to supply the paper strips and attach them to the spine of the notebook.

[0094] The cutting mechanism 10 is used to cut the paper strips.

[0095] The installation positions and working principles of the drying mechanism 7, the third gluing device 8, the backing wrapping mechanism, and the cutting mechanism 10 are all conventional technologies of existing cold glue backing machines and are existing technologies. They will not be explained in detail here. For details, please refer to the Chinese utility model patent with patent number CN202220545117.8.

[0096] The above description of a cold glue backing machine for uniform glue application is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
