Description

TECHNICAL FIELD

[0001] The utility model relates to printing equipment technical field, specifically a book binding glue scraping device. BACKGROUND

[0002] The book binding glue scraping device is a very important part of printing equipment, and is widely used in the printing industry. The book binding glue scraping device needs to scrape the glue on the spine after the glue device glues the spine of the book, so as to avoid overflow caused by too much glue or poor adhesion caused by too little glue, thereby ensuring the binding effect of the book. Therefore, the book binding glue scraping device is mainly used to control the uniformity of glue spreading and thickness, ensure the firm adhesion of the book core and cover, and improve the binding quality.

[0003] The prior art also has the following disadvantages:

[0004] 1. The existing book binding glue scraping device has the problem that the hot melt glue on the glue roller solidifies on the surface of the glue roller during long-time operation, which causes the distance between the glue roller and the spine to become short, the glue application effect to become poor, and the binding quality to be affected.

[0005] 2. The existing book binding glue scraping device also has the problem that the glue scraping effect is not ideal when scraping the glue on the spine. After the hot melt glue is applied to the spine by the glue roller, the hot melt glue needs to be scraped off by the scraper to ensure firm adhesion and avoid overflow. The existing technology has poor glue scraping effect. UTILITY MODEL CONTENTS

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution:

[0026] A bookbinding glue scraping device includes a base (1), a transmission box 2 fixedly connected to the top of the base 1, a slide groove 3 opened inside the transmission box 2, a movable rod 4 slidably connected inside the slide groove 3, a spine scraper 5 fixedly connected above the movable rod 4, an upper glue roller scraper 6 fixedly connected to one side of the movable rod 4, a glue trough 7 fixedly connected above the base 1, an upper glue roller 8 rotatably connected to the inner side of the glue trough 7, the upper glue roller scraper 6 being in contact with the surface of the upper glue roller 8, and a motor 9 fixedly connected to one side of the glue trough 7. The output end is coaxially and fixedly connected to the glue roller 8. The bottom of the glue tank 7 is equipped with an electric heating wire. When the motor 9 is started, the glue roller 8 is driven to rotate. The lower part of the glue roller 8 is immersed in the hot melt glue in the glue tank 7. When the glue roller 8 rotates, it carries out the hot melt glue and applies it to the spine. The movable rod 4 reciprocates inside the slide groove 3, driving the spine scraper 5 to scrape off the glue applied to the spine. When the movable rod 4 moves, it also drives the glue roller scraper 6 to move synchronously, and the glue roller scraper 6 scrapes off the surface of the glue roller 8.

[0027] A pulley 10 is rotatably connected to the side of the glue tank 7 away from the motor 9. The pulley 10 is fixedly connected to the upper glue roller 8. A pulley 21 is rotatably connected to one side of the transmission box 2. A belt is fitted between the pulley 10 and the pulley 21. A double-acting screw 12 is rotatably connected inside the transmission box 2. One end of the double-acting screw 12 is fixedly connected to the pulley 21. When the upper glue roller 8 rotates, it drives the pulley 10 to rotate. The pulley 10 drives the double-acting screw 12 inside the transmission box 2 to rotate through the belt and the pulley 21. When the double-acting screw 12 rotates, it drives the movable rod 4, which is threaded to it, to reciprocate.

[0028] An upper glue roller scraper 13 is provided on the inner side of the glue tank 7. Both ends of the upper glue roller scraper 13 are fixedly connected to connecting blocks 14. Adjustment grooves 15 are provided on both sides of the glue tank 7. The connecting blocks 14 are located inside the adjustment grooves 15 and are slidably connected to them. Two mounting plates 16 are fixedly connected to both sides of the glue tank 7. The two mounting plates 16 are located on both sides of the adjustment grooves 15. An adjustment screw 17 is rotatably connected between the two mounting plates 16. The adjustment screw 17 passes through the connecting block 14 and is threadedly connected to it. An adjustment knob 18 is fixedly connected to one end of the adjustment screw 17. When it is necessary to adjust the thickness of the hot melt adhesive on the surface of the upper glue roller 8, the adjustment knob 18 is rotated, which drives the adjustment screw 17 to rotate. The adjustment screw 17 drives the connecting block 14 threadedly connected to it to move, thereby driving the upper glue roller scraper 13 to move closer to or away from the upper glue roller 8, so as to achieve the thickness of the hot melt adhesive on the surface of the upper glue roller 8.

[0029] The working principle of this utility model is as follows:

[0030] The motor 9 is started, driving the gluing roller 8 to rotate. The lower part of the gluing roller 8 is immersed in hot melt adhesive in the glue tank 7. When the gluing roller 8 rotates, it carries out the hot melt adhesive and applies it to the spine. As the gluing roller 8 rotates, it drives the pulley 10 to rotate. The pulley 10 drives the double-acting screw 12 inside the transmission box 2 to rotate via a belt and pulley 11. When the double-acting screw 12 rotates, it drives the movable rod 4, which is threaded to it, to reciprocate. The movable rod 4 drives the spine scraper 5 to scrape off the glue applied to the spine, which can make the adhesion firm and prevent glue overflow. During the movement of the movable rod 4, it also drives the gluing roller scraper 6 to move synchronously. The gluing roller scraper 6 scrapes off the surface of the gluing roller 8, which can effectively prevent the hot melt adhesive from solidifying on the surface of the gluing roller 8, ensuring the gluing effect and thus improving the binding quality. When it is necessary to adjust the thickness of the hot melt adhesive on the surface of the glue roller 8, turn the adjustment knob 18 to drive the adjustment screw 17 to rotate. The adjustment screw 17 drives the connecting block 14 connected to it to move, thereby driving the glue roller scraper 13 to move closer to or further away from the glue roller 8, so as to adjust the thickness of the hot melt adhesive on the surface of the glue roller 8 to adapt to different glue application requirements.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
