Description

Technical Field

[0001] This invention relates to the field of book and periodical flattening technology, and more specifically to a flattening device for book and periodical production. Background Technology

[0002] A flattening machine is a specialized piece of equipment mainly used to flatten thin paper, leather, and corrugated paper after they have been coated with glue.

[0003] A mechanically automated flattening device is disclosed in patent CN114261807B, including a worktable with a groove in the worktable and a conveying mechanism in the groove. A guide hopper for use with the conveying mechanism is provided on one side of the worktable. A symmetrically arranged material placement frame is fixedly installed on the upper end of the side of the worktable away from the guide hopper, and symmetrically arranged push grooves are provided through the lower ends of both sides of the material placement frame.

[0004] The aforementioned technologies have the following drawbacks: First, they only level the top of the books and periodicals, without leveling the bottom. Unevenness is likely to occur at the bottom of the books and periodicals, and it is difficult to detect. This can lead to wrinkles at the bottom after flattening. In addition, when flattening the books and periodicals, the pressure is applied directly to the conveyor belt. The conveyor belt is not a rigid structure and cannot provide stable support, making it difficult to guarantee the flattening effect of the books and periodicals and easily causing damage to the conveyor belt.

[0054] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0055] Example 1: Please refer to Figure 1 - Figure 7 A book and magazine production flattening device includes a conveyor 1 and a flattening mechanism. The flattening mechanism includes a support 3 installed on the top of the conveyor 1, a plurality of hydraulic cylinders 4 installed on the top of the support 3, and a pressure plate 5 installed on the extended end of the plurality of hydraulic cylinders 4. The pressure plate 5 is located inside the support 3. The conveyor 1 is a belt conveyor. By controlling the hydraulic cylinders 4 to extend downward, the pressure plate 5 is driven to move downward, which can flatten the books and magazines. In addition, a drying mechanism (existing technology) can also be set on the conveyor 1 to dry the books and magazines, and a leveling mechanism (existing technology) can also be set to level the top of the books and magazines.

[0056] Also includes:

[0057] There are multiple feeding frames 2, all of which are installed outside the conveyor belt of the conveyor 1. The horizontal distance between two adjacent feeding frames 2 is the same. The upper edge of the feeding frame 2 is at the same horizontal height as the upper edge of the conveyor 1 frame. The conveyor 1 is controlled to drive the feeding frames 2 to move at equal distances, and the feeding frames 2 move in segments. After moving a certain distance, they stop for a while.

[0058] A positioning mechanism is installed on the top of the feeding frame 2 to position the books and periodicals. The positioning mechanism includes a limiting frame 6 installed on the top of the feeding frame 2 and a limiting plate 7 slidably connected inside the limiting frame 6. The side of the limiting frame 6 near the directional feeding mechanism has an open structure. The bottom of the limiting plate 7 has a structural groove. When the leveling strip 16 is detached from the bottom of the books and periodicals, it moves into the structural groove. A plurality of first springs 8 are fixedly connected to the outer wall of one side of the limiting plate 7. The other end of the plurality of first springs 8 is fixedly connected to the inner wall of the limiting frame 6. A first limiting block 9 is also fixedly connected inside the limiting frame 6. The first limiting block 9 is used to limit the position of the limiting plate 7.

[0059] The books are guided into the limiting frame 6 by the directional feeding mechanism along the top of the feeding frame 2 and the bottom support plate 15. The limiting frame 6 prevents the books from tilting during movement until one end of the books abuts against the limiting plate 7, thus completing the positioning of the books before flattening after feeding.

[0060] An directional feeding mechanism is installed on the top of the conveyor 1 and is used to directionally feed the books and periodicals to be flattened into the positioning mechanism. The directional feeding mechanism includes a feeding frame 10 installed on the top of the conveyor 1 and two first cylinders 11 respectively installed on the outer walls of both sides of the feeding frame 10. Both ends of the feeding frame 10 are provided with guide ports 12. The extended ends of the two first cylinders 11 are fixedly connected to connecting blocks 13, and L-shaped feeding plates 14 are fixedly connected to the outer wall of the connecting blocks 13 near the feeding frame 10.

[0061] By controlling the first cylinder 11 to shorten, the connecting block 13 is moved toward the feeding frame 10, which in turn drives the feeding plate 14 to guide some of the books and periodicals inside the feeding frame 10 into the top of the feeding frame 2 through the guide port 12, and at the same time enter the limiting frame 6. Then, the first cylinder 11 is controlled to extend, and the feeding plate 14 is reset through the connecting block 13, ready for the next feeding.

[0062] A bottom-leveling mechanism, installed inside the feeding frame 2, is used to level the bottom of the books and periodicals conveyed to the positioning mechanism. The bottom-leveling mechanism includes a bottom support plate 15 slidably mounted inside the feeding frame 2, two hidden slots on the top of the bottom support plate 15, leveling strips 16 respectively disposed within the two hidden slots, and two linkage components for driving the two leveling strips 16 to move vertically and horizontally. Before flattening, the upper edges of the leveling strips 16, the upper edges of the bottom support plate 15, and the upper edges of the feeding frame 2 are at the same horizontal level, and the thickness of the leveling strips 16 is 1 mm. The outer walls of the two leveling strips 16 on opposite sides are provided with inclined grooves. The linkage assembly includes two first transmission cylinders 17 installed on the inner wall of the bottom of the feeding frame 2 and a second transmission cylinder 21 installed inside the feeding frame 2. A first piston 18 is installed inside the first transmission cylinder 17. A driven rod 19 is installed on the top of the first piston 18. The top of the driven rod 19 is fixed to the bottom of the bottom support plate 15. A second spring 20 is fixed to the bottom of the first piston 18. A second limiting block 42 is installed inside the first transmission cylinder 17 to limit the first piston 18. The position is such that the first piston 18 will not block the first conduit 22; the second transmission cylinder 21 is located between the two first transmission cylinders 17, and the second transmission cylinder 21 is connected to the first transmission cylinder 17 through the first conduit 22. The second piston 23 is installed inside the second transmission cylinder 21, and a second conduit 24 is fixedly connected to one side of the outer wall of the second piston 23. The other end of the second conduit 24 extends to the outside of the second transmission cylinder 21 and is fixedly connected to the first telescopic rod 25; multiple oil guide ports 26 are opened on the outer wall of the second conduit 24, and the oil guide ports 26 are located in the second Inside the transmission cylinder 21; the first telescopic rod 25 is set along the height direction of the feeding frame 2, the top of the first telescopic rod 25 is fixedly connected to the third transmission cylinder 27, the third transmission cylinder 27 is installed inside the third transmission cylinder 27, the top of the third piston 28 is fixedly connected to the lifting rod 29, the top of the lifting rod 29 is fixedly connected to the bottom of the leveling strip 16, the bottom support plate 15 has a sliding groove 31 inside, and the lifting rod 29 is located inside the sliding groove 31; the second conduit 24 is connected to the third transmission cylinder 27 through the third conduit 30, which is a metal braided hose;

[0063] When the pressure plate 5 moves down and contacts the top of the book, it begins to move the bottom support plate 15 downward through the book. The bottom support plate 15 moves the driven rod 19 downward, which in turn moves the first piston 18 downward along the inner wall of the first transmission cylinder 17. This allows the hydraulic oil inside the first transmission cylinder 17 to be input into the second transmission cylinder 21 through the first conduit 22. At the same time, the second conduit 24 and the third conduit 30 first move the third piston 28 upward, which in turn moves the leveling strip 16 upward by 1 mm through the lifting rod 29, disengaging it from the hidden groove. As the hydraulic oil continues to be injected into the two second transmission cylinders 21, the two second pistons 23 inside the two second transmission cylinders 21 move away from each other. This, in turn, moves the two leveling strips 16 away from each other through the second conduit 24, the first telescopic rod 25, the third transmission cylinder 27, and the lifting rod 29, and completely detaches the two leveling strips 16 from the bottom of the book. In this process, the bottom of the book is leveled, solving the problem that the bottom of the book is a blind spot that cannot be leveled before flattening, and further avoiding the problem that wrinkles easily appear on the bottom of the book after flattening.

[0064] When the pressure plate 5 moves upward, the rebound force of the second spring 20 will drive the first piston 18 to move upward and reset, and the second guide tube 24, the third transmission cylinder 27, the lifting rod 29 and the leveling bar 16 will also reset accordingly.

[0065] An auxiliary connecting mechanism is respectively installed on the feeding frame 2 and the conveyor 1 to establish a connection between the feeding frame 2 and the frame of the conveyor 1. The auxiliary connecting mechanism includes two insert blocks 32 that slide inside the feeding frame 2 and two slots 33 that are respectively opened on the inner walls of the frame on both sides of the conveyor 1. The top of each of the two insert blocks 32 on opposite sides is provided with a sloping groove 34. When the bottom support plate 15 moves downward and abuts against the sloping groove 34, it drives the insert block 32 to move into the slot 33. Both sides of the insert block 32 are provided with movable grooves. Both movable grooves are set inside the feeding frame 2. A slider is slidably connected inside the two movable grooves. The slider is fixedly connected to the insert block 32. A return spring is fixedly connected to the outer wall of one side of the slider. The other end of the return spring is fixedly connected to the inner wall of the movable groove.

[0066] When the feeding frame 2 moves to the inside of the support 3, the conveyor 1 stops running. At this time, the insert block 32 is aligned with the slot 33. When the pressure plate 5 moves down and drives the bottom support plate 15 to move down, the bottom support plate 15 abuts against the inclined grooves 34 on both sides, driving the two insert blocks 32 to move away from each other and insert into the two slots 33 respectively. At the same time, the slider moves along the inner wall of the movable groove, the return spring is compressed, and the bottom support plate 15 moves down to the top of the first transmission cylinder 17 and stops moving. At this time, the two ends of the bottom support plate 15 abut against the opposite ends of the two insert blocks 32 respectively, so that the insert blocks 32 are always inserted into the slots 33. Therefore, when the pressure plate 5 flattens the books and magazines, the pressure on the feeding frame 2 will act on the frame of the conveyor 1, rather than on the conveyor belt of the conveyor 1. This avoids the problem that the conveyor belt is easily deformed and affects the flattening effect of the books and magazines, reduces the wear on the conveyor belt, and plays a role in protecting the conveyor belt.

[0067] During the upward reset process of the bottom support plate 15, the rebound force of the reset spring drives the slider to reset, thereby causing the two insert blocks 32 to move closer to each other and move out of the slot 33, thus disconnecting the feeding frame 2 from the frame, so that the feeding frame 2 can continue to be conveyed.

[0068] An directional feeding mechanism is installed on the top of the conveyor 1 to orient the flattened books and periodicals. The directional feeding mechanism includes a receiving platform installed on one side of the top of the conveyor 1 and a second cylinder 35 installed on the other side of the top of the conveyor 1. The upper edge of the receiving platform is at the same level as the upper edge of the frame of the conveyor 1. A push block is fixedly connected to the extended end of the second cylinder 35. A through slot 36 is opened on the other side of the limiting frame 6. When the second cylinder 35 extends, it drives the push block to pass through the through slot 36 and drives the limiting plate 7 to move.

[0069] When the conveyor 1 drives the feeding frame 2 to move to the middle of the second cylinder 35 and the receiving platform, the conveyor 1 stops running. At this time, the push block is aligned with the through groove 36. By controlling the extension of the second cylinder 35, the push block is driven through the through groove 36 to drive the limiting plate 7 to move. The first spring 8 is stretched accordingly. When the limiting plate 7 moves, it drives the books inside the limiting frame 6 to the top of the receiving platform. When the second cylinder 35 retracts, the rebound force of the first spring 8 drives the limiting plate 7 to move back until it abuts against the first limiting block 9.

[0070] Example 2: Please refer to Figure 8This embodiment provides a technical solution based on embodiment 1: the inside of the feeding frame 2 is also provided with a compensation mechanism, which includes a third cylinder 37 fixed to the inner wall of the feeding frame 2, a displacement block 41 fixed to the extended end of the third cylinder 37, a fourth cylinder 38 installed on the top of the displacement block 41, and compensation strips 39 installed on the extended ends of the multiple fourth cylinders 38; multiple second telescopic rods 40 are also fixed to the outer wall of one side of the displacement block 41, and the other end of the multiple second telescopic rods 40 is fixed to the inner wall of the feeding frame 2; the compensation strips 39 are adapted to the slide groove 31;

[0071] After the two leveling strips 16 are moved away from each other and the bottom of the book is leveled, the third cylinder 37 is controlled to move the displacement block 41 and the compensation strip 39 on its top to the bottom of the slide 31. Then, the fourth cylinder 38 is controlled to extend and move the compensation strip 39 into the interior of the slide 31, so that the upper edge of the compensation strip 39 is at the same level as the upper edge of the bottom support plate 15.

[0072] Working principle: During use, the control conveyor 1 moves the unloading frame 2 until it aligns with the loading frame 10 and then stops. The first cylinder 11 is then shortened, causing the connecting block 13 to move towards the loading frame 10. This, in turn, causes the loading plate 14 to guide some books from inside the loading frame 10 through the guide port 12 to the top of the unloading frame 2. Simultaneously, the books enter the limiting frame 6, where the limiting frame 6 prevents the books from tilting during movement. The books continue to be positioned before being flattened after loading until one end abuts against the limiting plate 7. The conveyor 1 then continues to move the unloading frame 2 to the right. When the unloading frame 2 moves into the support 3 and the insert block 32 aligns with the slot 33, the conveyor 1 stops. The control hydraulic cylinder 4 extends downwards, causing the pressure plate to... 5. Moving downwards, when the pressure plate 5 contacts the top of the book, it begins to move the bottom support plate 15 downwards via the book. The bottom support plate 15 moves the driven rod 19 downwards, which in turn moves the first piston 18 downwards along the inner wall of the first transmission cylinder 17. This allows the hydraulic oil inside the first transmission cylinder 17 to be input into the second transmission cylinder 21 through the first conduit 22. Simultaneously, the third piston 28 is moved upwards via the second conduit 24 and the third conduit 30, which in turn moves the leveling bar 16 upwards by 1 mm via the lifting rod 29, disengaging it from the hidden groove. As hydraulic oil continues to be injected into the two second transmission cylinders 21, the two second pistons 23 inside the two second transmission cylinders 21 move away from each other, and then move through the second conduit 24 and the first telescopic rod 25... The third transmission cylinder 27 and the lifting rod 29 drive the two leveling strips 16 away from each other, and completely detach the two leveling strips 16 from the bottom of the book. In this process, the bottom of the book is leveled, solving the problem that the bottom of the book is a blind spot that cannot be leveled before flattening, and further avoiding the problem that the bottom of the book is prone to wrinkles after flattening. At the same time, when the pressure plate 5 moves down and drives the bottom support plate 15 to move down, when the bottom support plate 15 abuts against the inclined grooves 34 on both sides, it drives the two insert blocks 32 away from each other and inserts them into the two slots 33 respectively. At the same time, the slider moves along the inner wall of the movable groove, the return spring is compressed, and the bottom support plate 15 moves down to the top of the first transmission cylinder 17 and stops moving. At this time, the two ends of the bottom support plate 15 are respectively opposite to the two insert blocks 32. The end abuts, ensuring that the insert block 32 remains inserted inside the slot 33. Therefore, when the pressure plate 5 flattens the books, the pressure on the feeding frame 2 acts on the frame of the conveyor 1, not on the conveyor belt. This avoids the problem of the conveyor belt easily deforming and affecting the flattening effect, reduces wear on the conveyor belt, and protects it. Then, the hydraulic cylinder 4 moves the pressure plate 5 upwards to reset, and the conveyor 1 continues to move the feeding frame 2. When the feeding frame 2 moves to the middle between the second cylinder 35 and the receiving platform, the conveyor 1 stops. At this point, the push block aligns with the slot 36. By controlling the extension of the second cylinder 35, the push block passes through the slot 36, driving the limit plate 7 to move. The first spring 8 is then stretched.When the limiting plate 7 moves, it drives the books and periodicals inside the limiting frame 6 to the top of the receiving platform.
