Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and in particular relates to an automatic gluing device for bookbinding. Background Technology

[0002] Automatic gluing devices play a crucial role in the bookbinding process. Traditional bookbinding methods mainly rely on manual gluing, which is not only inefficient but also prone to uneven gluing, affecting the binding effect. In addition, manual operation also suffers from insufficient precision and inconsistent speed, which not only increases the workload of workers but also limits the improvement of binding efficiency. To address this, a device that can automatically and efficiently apply glue has been developed, which improves gluing efficiency and precision to a certain extent.

[0003] Existing automatic gluing devices for bookbinding require workers to smooth the glue after application. When gluing manually, it is difficult to ensure that the glue quality of each book is ideal. Uneven glue application will lead to inconsistent bookbinding results, thus affecting the quality and appearance of the finished product.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] This utility model addresses the problem in existing technologies where workers are required to smooth out the glue, which makes it difficult to ensure that the glue application quality is ideal for every book. Uneven glue application leads to inconsistent bookbinding results, affecting the quality and aesthetics of the finished product. The following technical solution is proposed:

[0008] The glue application assembly includes a roller, a mounting component, a glue storage tank, a drive rod, a moving component, and a barrier component. The roller is connected to the body of the glue application equipment via the mounting component. The glue storage tank is connected to the mounting component. The drive rod, the moving component, and the barrier component are vertically installed inside the glue storage tank. Through the cooperation of the drive rod, the moving component, and the barrier component, the glue inside the glue storage tank flows to the outer surface of the roller.

The ball valve is connected to the mounting bracket via the elastic element, and the mounting bracket is connected to the barrier component. A groove is provided inside the barrier component, and the outer surface of the ball valve fits into the groove.

[0010] As a preferred embodiment of the above technical solution, the moving part is provided with a connecting rod at the top, an elastic element two at the bottom, and a cam on the driving rod. Through the cooperation of the connecting rod, the elastic element two, and the cam, the moving part can reciprocate in a vertical direction.

[0011] As a preferred embodiment of the above technical solution, the mounting component is provided with multiple positioning blocks, and the body of the adhesive applicator is provided with multiple sliding grooves, and the positioning blocks move horizontally within the sliding grooves.

[0012] As a preferred embodiment of the above technical solution, the surfaces of the drive rod and one of the positioning blocks are provided with a movable rod, and the end of the movable rod away from the drive rod and the positioning block is provided with a slider. The slider drives the movable rod to move horizontally within the outer shell of the glue coating equipment and the machine body of the glue coating equipment.

[0013] As a preferred embodiment of the above technical solution, multiple mounting brackets are provided, and the multiple mounting brackets are distributed in a ring on the barrier.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This utility model provides an automatic gluing device for bookbinding, such as... Figures 1 to 6As shown, it includes: a glue-applying equipment housing 1 and a glue-applying assembly. The glue-applying equipment housing 1 houses the glue-applying equipment body 2, and the housing is located on both sides of the body 2 to protect it. The glue-applying assembly includes rollers 3, mounting parts 4, a glue storage tank 5, a drive rod 6, a moving part 7, and a barrier part 8. The rollers 3 are glue-applying rollers. The glue storage tank 5 stores the glue used in bookbinding. The glue-applying equipment housing 1 and the body 2 are mounted together with screws. The two parts are disassembled to facilitate the addition of adhesive to the glue storage tank 5 and the cleaning of the roller 3 and the interior of the glue coating equipment body 2. Gears are provided at both ends of the drive rod 6, and a rack meshing with the gears is located inside the glue coating equipment body 2. When the drive rod 6 moves, the meshing of the gears and rack drives the drive rod 6 to rotate. The surface of the moving part 7 is in contact with the inner wall of the glue storage tank 5. The roller 3 is connected to the glue coating equipment body 2 via the mounting part 4, and the glue storage tank 5 is connected to the mounting part. 4. The drive rod 6, the moving part 7, and the blocking part 8 are installed vertically inside the glue storage tank 5. Through the cooperation of the drive rod 6, the moving part 7, and the blocking part 8, the glue inside the glue storage tank 5 flows to the outer surface of the roller 3. The moving part 7 has a connecting rod 12 at the top and an elastic element 13 at the bottom. Both the elastic element 13 and the elastic element 10 are springs. The drive rod 6 has a cam 14. The top of the connecting rod 12 always keeps in contact with the surface of the cam 14. Through the connecting rod 12 and the elastic element 14, the glue flows to the outer surface of the roller 3. The cooperation of cam 13 and cam 14 causes the moving part 7 to reciprocate vertically; the mounting part 4 is provided with multiple positioning blocks 15, and multiple sliding grooves are opened inside the glue coating equipment body 2, and the positioning blocks 15 can move horizontally inside the sliding grooves; the drive rod 6 and the positioning blocks 15 are rotatably connected to the moving rod 16, and the end of the moving rod 16 away from the drive rod 6 and the positioning blocks 15 is provided with a slider 17, which drives the moving rod 16 to move horizontally inside the glue coating equipment shell 1 and the glue coating equipment body 2.

[0031] The adhesive liquid applied to the body 2 of the adhesive applicator is smoothed by the cooperation between the adhesive storage tank 5 and the roller 3, making the adhesive application inside the body 2 more uniform. This effectively avoids the problem of air bubbles forming inside the adhesive layer, thereby improving the quality and appearance of the finished binding product.

[0032] In use, when staff need to apply glue to books, the slider 17 first pushes two moving rods 16 to move. During the movement, the two moving rods 16 drive the positioning block 15 and the drive rod 6 to move synchronously. The positioning block 15 drives the mounting part 4 to move, and the drive rod 6 drives the glue storage tank 5 to move synchronously with the mounting part 4, rotating along the rack inside the glue application equipment body 2. When the drive rod 6 rotates, it drives the cam 14 to rotate. When the cam 14 rotates, it pushes the moving part 7 downward through the connecting rod 12. After the moving part 7 moves downward, it compresses and deforms the elastic element 13. The reaction force generated by the deformed elastic element 13 pushes the connecting rod 12 through the moving part 7 to always keep it in contact with the surface of the cam 14. Through the cooperation between the connecting rod 12 and the cam 14, the moving part 7 is kept in contact with the surface of the cam 14. The glue tank 5 moves vertically back and forth inside, squeezing the glue inside. The glue is then discharged from the tank onto the surface of the roller 3. During this movement, the roller 3 spreads the glue onto the inside of the glue applicator body 2. The roller 3 stops moving from one side of the body 2 to the other. The operator then places the side of the book to be glued inside the body 2, allowing the book pages to adhere to the glue. This completes the glue application process. The cooperation between the glue tank 5 and the roller 3 smooths the glue applied to the body 2, resulting in a more even application and effectively preventing air bubbles from forming within the glue layer. This improves the quality and appearance of the finished binding.

[0033] Specifically, the glue coating equipment housing 1 houses the glue coating equipment body 2, and the housing 1 is mounted on both sides of the body 2 with screws. A mounting component 4 is slidably connected inside the body 2, and a roller 3 is rotatably connected inside the mounting component 4. A glue storage tank 5 is fixedly connected to the top of the mounting component 4, and a drive rod 6 is rotatably connected inside the glue storage tank 5. A cam 14 is located at the center of the surface of the drive rod 6. A barrier 8 is fixedly connected inside the glue storage tank 5 below the cam 14, and the top of the barrier 8 is secured by an elastic element 13. A movable part 7 is fixedly connected, and a connecting rod 12 is fixedly connected to the top of the movable part 7. The connecting rod 12 and the surface of the cam 14 are in contact with each other. Multiple positioning blocks 15 are fixedly connected to the mounting part 4, and the mounting part 4 slides inside the glue coating equipment body 2 through the positioning blocks 15. One of the positioning blocks 15 and one end of the drive rod 6 are rotatably connected to a movable rod 16. The other ends of the two movable rods 16 are fixedly connected to the same slider 17, and the slider 17 drives the two movable rods 16 to move simultaneously inside the glue coating equipment shell 1 and the glue coating equipment body 2.

[0034] To address the issue of preventing the adhesive discharged from the adhesive storage tank 5 from being sucked in when the moving part 7 moves upward, as described in the above example, the following solution is proposed: Figure 5 and Figure 6 As shown, it also includes a barrier assembly, which includes a mounting bracket 9, an elastic element 10, and a ball valve 11. The ball valve 11 is connected to the mounting bracket 9 through the elastic element 10. The mounting bracket 9 is connected to the barrier assembly 8. The barrier assembly 8 has a groove inside, and the outer surface of the ball valve 11 fits into the groove. There are multiple mounting brackets 9, which are arranged in a ring on the barrier assembly 8. The number of elastic elements 10 and ball valves 11 corresponds one-to-one with the number of mounting brackets 9.

[0035] By cooperating with the mounting bracket 9, the elastic element 10 and the hemispherical valve 11, the problem of the adhesive being sucked into the glue tank 5 when the moving part 7 moves upward is avoided, thereby improving the stability of the glue tank 5 when applying adhesive to the surface of the roller 3, and thus reducing the unstable factors in the adhesive application process.

[0036] In use, when the moving part 7 moves downward, it pushes the airflow between the blocking part 8 and the moving part 7 along the gap between the hemispherical valve 11 and the blocking part 8 into the glue storage tank 5, and pushes the hemispherical valve 11 into the glue storage tank 5. When the hemispherical valve 11 moves, it causes the elastic part 10 to stretch. When the moving part 7 moves upward, it is impossible to push the hemispherical valve 11 to move through the gas between the moving part 7 and the blocking part 8. At this time, the elastic part 10 rebounds and causes the hemispherical valve 11 to move in the opposite direction until the surface of the hemispherical valve 11 is in contact with the inner wall of the blocking part 8, at which point the movement stops. Through the cooperation between the hemispherical valve 11 and the blocking part 8, the problem of the glue discharged from the glue storage tank 5 being sucked in when the moving part 7 moves upward is avoided, thereby improving the stability of the glue storage tank 5 when applying glue to the surface of the roller 3, and reducing the unstable factors in the glue application process.

[0037] Specifically, a mounting bracket 9 is fixedly connected to the surface of the barrier 8, and an elastic element 10 is fixedly connected to the bottom of the mounting bracket 9. A hemispherical valve 11 is fixedly connected to the other end of the elastic element 10, and the other end of the hemispherical valve 11 is in contact with the barrier 8. There are multiple mounting brackets 9, which are arranged in a circular array around the axis of the barrier 8, and a mounting bracket 9 is also provided at its center. The number of elastic elements 10 and hemispherical valves 11 corresponds one-to-one with the number of mounting brackets 9.

[0038] Working Principle: When the device is in use, if the operator needs to apply glue to the book, the slider 17 first pushes the two moving rods 16 to move. During the movement, the two moving rods 16 drive the positioning block 15 and the drive rod 6 to move synchronously. The positioning block 15 drives the mounting part 4 to move, and the drive rod 6 drives the glue storage tank 5 to move synchronously with the mounting part 4, rotating along the rack inside the glue application equipment body 2. When the drive rod 6 rotates, it drives the cam 14 to rotate. When the cam 14 rotates, it pushes the moving part 7 downward through the connecting rod 12. After the moving part 7 moves downward, it compresses and deforms the elastic element 13. The reaction force generated by the deformed elastic element 13 pushes the connecting rod 12 to always be in contact with the surface of the cam 14 through the moving part 7. Through the cooperation between the connecting rod 12 and the cam 14, the moving part 7 moves downward. The component 7 moves vertically back and forth inside the glue storage tank 5, squeezing the glue inside the tank. The glue storage tank 5 then discharges the glue onto the surface of the roller 3. During this movement, the roller 3 spreads the glue onto the inside of the glue coating equipment body 2. The roller 3 stops moving after moving from one side to the other inside the glue coating equipment body 2. Then, the staff places the side of the book that needs to be coated with glue inside the glue coating equipment body 2, allowing the book pages to adhere to the glue, thus completing the glue coating process. Through the cooperation between the glue storage tank 5 and the roller 3, the glue applied to the glue coating equipment body 2 is smoothed out, making the glue coating inside the glue coating equipment body 2 more uniform. This effectively avoids the problem of air bubbles forming inside the glue layer, thereby improving the quality and appearance of the finished binding product.

[0039] When the moving part 7 moves downward, it pushes the airflow between the blocking part 8 and the moving part 7 along the gap between the hemispherical valve 11 and the blocking part 8 into the glue storage tank 5, and pushes the hemispherical valve 11 into the glue storage tank 5. When the hemispherical valve 11 moves, it causes the elastic element 10 to stretch. When the moving part 7 moves upward, it is impossible to push the hemispherical valve 11 to move through the gas between the moving part 7 and the blocking part 8. At this time, the elastic element 10 rebounds and causes the hemispherical valve 11 to move in the opposite direction until the surface of the hemispherical valve 11 is in contact with the inner wall of the blocking part 8, and then stops moving. Through the cooperation between the hemispherical valve 11 and the blocking part 8, the problem of sucking in the glue discharged from the glue storage tank 5 when the moving part 7 moves upward is avoided, thereby improving the stability of the glue storage tank 5 when applying glue to the surface of the roller 3, and reducing the unstable factors in the glue application process.
