Description

Technical Field

[0001] The utility model relates to the technical field of book block processing equipment, in particular to a book block side gluing mechanism. Background Art

[0002] During the book block processing, gluing the sides of the book block spine is a key step in the processing process. The gluing effect has a direct impact on the binding quality and appearance of the book block. The design of the gluing equipment needs to meet the requirements of uniform gluing, controllable gluing amount, and high production efficiency. However, the existing gluing equipment is as follows:

[0003] The Chinese patent document with announcement number CN214295170U discloses a book block side gluing mechanism suitable for a fully automatic binding machine, which specifically discloses: a gluing drive shaft and a support shaft are arranged in parallel on the two end plates of the side glue pot; a front driven frame and a rear transmission frame are movably mounted on the support shaft, and a pair of side glue rollers are arranged on the upper end thereof through a transmission vertical shaft; and a transmission bevel gear is arranged on the transmission vertical shaft; a gluing gear is provided on the gluing drive shaft, and a transmission sprocket is fixedly arranged at one end of the gluing drive shaft; the rear transmission frame is drive-connected to the rear frame adjustment screw, and an adjustment driven sprocket is fixedly arranged at one end of the rear frame adjustment screw; the front driven frame is drive-connected to the front frame adjustment screw on the side glue pot.

[0004] As can be seen from the above, existing gluing mechanisms apply glue to both sides of the book block spine using a pair of side glue rollers. Furthermore, the spacing between the side glue rollers can be adjusted, making them suitable for gluing the sidewalls of the spine of book blocks of varying thicknesses, while ensuring a stable glue layer thickness and width. However, existing gluing mechanisms lack a continuous glue supply during the gluing process, resulting in an unstable glue supply, prone to glue breakage, and uneven glue application, impacting both the gluing effect and the subsequent processing quality of the book block. Therefore, a book block side gluing mechanism is provided to address the aforementioned technical issues. Utility Model Content

[0030] The following is a detailed description of a book block side gluing mechanism of the present invention with reference to the accompanying drawings.

[0031] like Figure 1-2 As shown, an embodiment of a book block side gluing mechanism of the present invention includes a mounting seat 1 and a support frame 2 detachably mounted on the mounting seat 1, wherein a first movable seat 3 and a second movable seat 4 are mounted on the support frame 2 and can move toward or away from each other, the first movable seat 3 and the second movable seat 4 are movable laterally and the movable direction is perpendicular to the conveying direction of the book block, a first gluing wheel 5 is horizontally rotatably provided on the first movable seat 3, a second gluing wheel 6 is horizontally rotatably provided on the second movable seat 4 and the rotation direction is opposite to the rotation direction of the first gluing wheel 5, and a gap is provided between the first gluing wheel 5 and the second gluing wheel 6 for the book block to pass through; a conveying device (such as Figure 7As shown in the figure, the book block is transported horizontally so that the portion of the book block that needs to be glued (the side edge of the book block spine) passes through the gap between the first glue coating wheel 5 and the second glue coating wheel 6. Glue is attached to the circumferential sides of the first glue coating wheel 5 and the second glue coating wheel 6. When the book block passes through, the first glue coating wheel 5 is driven to rotate counterclockwise, and the second glue coating wheel 6 is driven to rotate clockwise, so that the first glue coating wheel 5 and the second glue coating wheel 6 roll on the two side edges of the bottom of the book block (the side edges of the book block spine) respectively, thereby coating glue on the two side edges of the bottom of the book block.

[0032] Furthermore, annular glue storage lines 62 are formed on the circumferential sides of the first and second gluing wheels 5, 6. By providing the glue storage lines 62, the glue can be fully adhered to the circumferential sides of the first and second gluing wheels 5, 6, avoiding the gluing effect being affected by the circumferential sides being too smooth. A vertically arranged rotating shaft 61 is installed on each of the first and second gluing wheels 5, 6. The rotating shaft 61 is rotatably mounted on the first and second movable seats 3, 4, respectively. The support frame 2 is equipped with a first transmission unit 10 for driving the rotating shaft 61 mounted on the first gluing wheel 5 to rotate, and a second transmission unit 11 for driving the rotating shaft 61 mounted on the second gluing wheel 6 to rotate. The first and second transmission units 10, 11 are operated simultaneously, and driven by the rotating shaft 61, thereby driving the first and second gluing wheels 5, 6 to rotate simultaneously in opposite directions, thereby achieving automatic gluing of the book block.

[0033] In addition, after controlling the first movable seat 3 and the second movable seat 4 to move closer to or away from each other, the spacing between the first gluing wheel 5 and the second gluing wheel 6 can be adjusted, so that book cores of different thicknesses can pass through the gap between the two to perform gluing on book cores of different thicknesses; and when adjusting the spacing between the first gluing wheel 5 and the second gluing wheel 6, the first transmission part 10 and the second transmission part 11 are always in transmission connection with the corresponding rotating shaft 61, so as to facilitate driving the first gluing wheel 5 and the second gluing wheel 6 in different positions. However, in order to control the first movable seat 3 and the second movable seat 4 to move closer to or away from each other, a forward and reverse threaded rod 18 is rotatably provided on the support frame 2, and the length direction of the forward and reverse threaded rod 18 is parallel to the sliding direction of the first movable seat 3 (or the second movable seat 4). The first movable seat 3 and the second movable seat 4 are respectively threadedly connected to different threaded portions on the forward and reverse threaded rod 18, and a hand wheel 19 is installed at the end of the forward and reverse threaded rod 18. When the distance between the first gluing wheel 5 and the second gluing wheel 6 needs to be adjusted, the staff shakes the hand wheel 19 to drive the forward and reverse screw rods 18 to rotate, thereby controlling the first movable seat 3 and the second movable seat 4 to move closer to or away from each other.

[0034] In order to ensure that there is always sufficient glue attached to the circumferential sides of the first and second gluing wheels 5, 6, a first glue supply unit 7 for supplying glue to the first gluing wheel 5 is installed on the first movable seat 3, and a second glue supply unit 8 for supplying glue to the second gluing wheel 6 is installed on the second movable seat 4. When the first and second gluing wheels 5, 6 are driven to rotate simultaneously in opposite directions, the first and second glue supply units 7, 8 are operated to continuously apply glue to the glue storage lines 62 of the first and second gluing wheels 5, 6. After the circumferential sides that have just been coated with glue come into contact with the sides of the book block, glue can be applied to the book block. In addition, a placement table 15 and a glue pump 9 are installed on the support frame 2. A glue storage barrel 16 for storing glue is placed on the placement table 15. The glue inlet end of the glue pump 9 is connected to the glue storage barrel 16, and the glue outlet end of the glue pump 9 is simultaneously connected to the first and second glue supply units 7, 8. While the first glue supply unit 7 and the second glue supply unit 8 are running, the glue pump 9 is run to extract the glue in the glue storage barrel 16 and then transport the glue to the first glue supply unit 7 and the second glue supply unit 8 respectively, thereby realizing automatic glue replenishment.

[0035] like Figure 3-5 As shown, the first glue supply part 7 and the second glue supply part 8 have the same structure and are arranged in a mirror image, wherein the second glue supply part 8 includes a movable block 81 arranged on the second movable seat 4 and movable in the direction of approaching or moving away from the second glue coating wheel 6, and the movable block 81 is equipped with a glue spreading member 83 for evenly spreading glue on the outer side of the circumference of the second glue coating wheel 6, and also includes a hose 84, one end of the hose 84 is connected to the glue spreading member 83, and the other end is connected to the glue pump 9; the glue pump 9 extracts the glue in the glue storage barrel 16 and supplies the glue to the glue storage barrel 16 through the hose 84. Water is transported to the gluing member 83, which then evenly applies glue to the outer circumference of the second gluing wheel 6. Furthermore, the movable block 81 is controlled to move on the second movable seat 4 toward or away from the second gluing wheel 6, thereby adjusting the distance between the gluing member 83 and the outer circumference of the second gluing wheel 6 to control the thickness of the glue applied (i.e., the amount of glue attached to the outer circumference of the second gluing wheel 6). The gluing member 83 is adjusted to a specified position according to the different amounts of glue required for different types of book blocks or book blocks of different thicknesses. An adjusting member 82 is also rotatably provided on the second movable seat 4 for controlling the movement of the movable block 81 on the second movable seat 4. The adjusting member 82 can be a small screw that is threadedly connected to the movable block 81. Rotating the small screw can control the movement of the movable block 81.

[0036] Furthermore, the second glue supply part 8 also includes a scraping part for scraping off excess glue on the outer side of the circumference of the second glue coating wheel 6. After the glue is applied to the outer side of the circumference of the second glue coating wheel 6 by the glue spreading part 83, the amount of glue on the outer side of the circumference of the second glue coating wheel 6 may be excess. Only adjusting the distance between the glue spreading part 83 and the outer side of the circumference of the second glue coating wheel 6 cannot achieve precise control of the glue application amount. After the glue spreading part 83 completes the glue application, the excess glue on the outer side of the circumference of the second glue coating wheel 6 is scraped off by the scraping part. After scraping off the excess glue, it contacts the side of the book block again. Under the action of the scraping part, the accuracy of the glue application is further improved, which not only saves costs but also improves the processing efficiency of the book block.

[0037] The scraping unit includes a fixed seat 85 mounted on the second movable seat 4. A movable rod 86 is slidably mounted on the fixed seat 85. A scraping member 87 is mounted on the movable rod 86 for contacting the outer circumference of the second glue-coating wheel 6. The movable rod 86 slides on the second movable seat 4 to drive the scraping member 87 toward or away from the second glue-coating wheel 6, thereby adjusting the amount of glue scraped. A scraping pattern 88 is formed on the side of the scraping member 87 to match the glue storage pattern 62. By providing the scraping pattern 88, the glue in the glue storage pattern 62 can be scraped off, thereby controlling the amount of glue in the glue storage pattern 62. A threaded rod 89 is rotatably provided on the movable rod 86, and its length direction is consistent with its sliding direction. The threaded rod 89 is threadedly connected to the fixed seat 85. By rotating the threaded rod 89, the movable rod 86 can be pulled or pushed to slide a specified distance on the fixed seat 85, thereby achieving precise control of the position of the scraper 87. Moreover, when the threaded rod 89 is not rotating, the scraper 87 can be placed in a position to move automatically.

[0038] In addition, a guide member 811 is installed below the glue spreading member 83 and the glue scraping member 87 for collecting and diverting the dripping glue, a funnel 17 is installed on the top of the glue storage barrel 16, and a gathering frame 14 is installed on the support frame 2 for collecting and diverting the glue flowing out of the guide member 811 into the funnel 17 for recovery; when the glue spreading member 83 applies glue to the outer side of the circumference of the second glue coating wheel 6, and the glue scraping member 87 scrapes glue to the outer side of the circumference of the second glue coating wheel 6, excess glue will drip down and then drip onto the guide member 811. A guide groove is formed on the guide member 811, and the glue is diverted into the gathering frame 14 through the guide groove, and then collected by the gathering frame 14, and finally diverted into the funnel 17 for recovery. The recycled glue flows back into the glue storage barrel 16, which is convenient for re-applying the recycled glue on the outer side of the circumference of the second glue coating wheel 6, saving the processing cost of the book core. The second movable seat 4 is provided with a protective frame 810 placed on the side of the second glue coating wheel 6. Under the action of the protective frame 810, the glue on the outer side of the circumference of the second glue coating wheel 6 is prevented from being thrown out during the process of driving the second glue coating wheel 6 to rotate, thereby improving the cleanliness of the glue coating machine.

[0039] like Figure 6 As shown, the first transmission part 10 includes a first universal joint 101 and a first gear 102 rotatably arranged on the support frame 2. The axis of rotation of the first gear 102 is arranged vertically. One end of the first universal joint 101 is fixedly connected to the center point of the first gear 102, and the other end is fixedly connected to the rotating shaft 61 arranged on the first rubber coating wheel 5. When the first gear 102 is driven to rotate, the rotating shaft 61 and the first rubber coating wheel 5 can be driven to rotate under the transmission action of the first universal joint 101.

[0040] Secondly, the second transmission part 11 includes a second universal joint 111 and a second gear 112 rotatably arranged on the support frame 2. The axis of rotation of the second gear 112 is arranged vertically. One end of the second universal joint 111 is fixedly connected to the center point of the second gear 112, and the other end is fixedly connected to the rotating shaft 61 arranged on the second glue coating wheel 6. The second gear 112 is engaged with the first gear 102; when the second gear 112 or the first gear 102 is driven to rotate, under the transmission action of the first universal joint 101 and the second universal joint 111, the first glue coating wheel 5 and the second glue coating wheel 6 are driven to rotate in opposite directions at the same time.

[0041] The support frame 2 is also equipped with a drive motor 12, and a third gear 13 is provided on the output shaft of the drive motor 12. The third gear 13 is engaged with the second gear 112 or the first gear 102. When the drive motor 12 is running, the third gear 13 is driven to rotate, thereby driving the second gear 112 or the first gear 102 to rotate.

[0042] like Figure 7 As shown, the conveying device includes a base 20, on which a first conveying portion 21 and a second conveying portion 22 cooperating with the first conveying portion 21 to press and convey the book core are installed. The first conveying portion 21 and the second conveying portion 22 are arranged side by side left and right or front and back, and a conveying track is formed between the first conveying portion 21 and the second conveying portion 22. The initial end of the conveying track is connected to a feeding device (not shown in the figure) for feeding the book core. The feeding device (not shown in the figure) intermittently conveys and feeds the book core, so that after the book core is conveyed to the initial ends of the first conveying portion 21 and the second conveying portion 22, the book core is clamped by the first conveying portion 21 and the second conveying portion 22. The first conveying portion 21 and the second conveying portion 22 are operated while clamping, and the clamped book core is conveyed and processed to realize the pressing and conveying of the book core. Moreover, during the conveying process, the bottom side edge of the book core (the side edge of the spine of the book core) passes between the first gluing wheel 5 and the second gluing wheel 6, and the sides of the first gluing wheel 5 and the second gluing wheel 6 roll on the bottom side edge of the book core to apply glue on the book core, and then the subsequent backing paper pasting process is carried out.

[0043] In addition, the gluing mechanism is placed directly below the first conveying portion 21 and the second conveying portion 22, and the mounting seat 1 is fixed on the base 20. By removing the support frame 2 from the mounting seat 1, the gluing mechanism can be repaired or maintained.

[0044] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0045] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
