Description

Technical Field

[0001] The invention relates to the technical field of book production, in particular to a book core shaping and multiple compacting mechanism and system. Background Art

[0002] In the book binding production process, the compaction of the book core is a crucial link. The quality of the book core compaction directly affects the overall quality, appearance and durability of the book. Good compaction can ensure that the paper inside the book core is tightly combined, reduce the problems of loose pages and deformation during the use of the book, and improve the stability and service life of the book.

[0003] At present, the existing book block compaction technology mainly has the following problems: 1. Limitations of one-time compaction Most traditional book core compaction methods use one-time compaction, that is, compacting the book core to the required thickness at one time. However, this method has obvious disadvantages. On the one hand, it is difficult to achieve the ideal compaction effect with one-time compaction. Due to differences in factors such as the material, thickness and number of layers of the paper inside the book core, applying a large pressure at one time may cause uneven compaction of parts of the book core, some paper may not be fully compacted, and some paper may be damaged due to excessive pressure. On the other hand, one-time compaction takes a long time. In order to achieve the required degree of compaction, it is necessary to apply a large pressure and maintain it for a long time, which not only reduces production efficiency, but also increases energy consumption and equipment wear.

[0004] 2. Inaccurate compaction pressure control In the process of compacting book cores, the control of compaction pressure is crucial. If the pressure is too small, the book core cannot be fully compacted, the sheets are not tightly bonded, and loose pages are likely to appear; if the pressure is too large, the book core paper may be deformed or damaged, affecting the appearance and quality of the book. Existing compaction equipment often has the problem of insufficient precision in pressure control. It is difficult to accurately adjust the compaction pressure according to different book core types and thicknesses, and thus cannot meet the needs of high-quality book production.

[0005] 3. Lack of effective book block position detection and conveying control During the book core compaction process, the position detection and conveying control of the book core are also important factors affecting the compaction effect. If the position of the book core is inaccurate during the conveying process, it may cause the compaction position to shift, affecting the compaction quality. At the same time, unreasonable conveying control may also cause the book core to move or shake during the compaction process, further affecting the compaction effect. Existing compaction equipment has deficiencies in book core position detection and conveying control, and cannot achieve accurate positioning and stable conveying of the book core.

[0006] 4. Difficult to adapt to mass production needs With the continuous expansion of the book market, higher requirements are put forward for the production efficiency and quality of books. Most of the existing book core compaction equipment cannot achieve efficient mass production and cannot meet the needs of large-scale production. During the mass production process, the equipment is required to be able to process a large number of book cores quickly and accurately and ensure that the compaction quality of each book core is consistent. However, the existing equipment has deficiencies in terms of automation level, production speed, and stability, making it difficult to meet this demand. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a book core shaping and multi-stage compaction mechanism and system, which solves the problems raised in the above background art.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: A book core shaping and multi-stage compaction mechanism, comprising: An equipment frame, on both sides of which an inlet conveyor belt and an outlet conveyor belt are respectively installed. The conveying end of the inlet conveyor belt and the conveying start end of the outlet conveyor belt both extend towards the interior of the equipment frame and are connected to each other; A primary compaction module, a secondary compaction module, and a tertiary compaction module, all installed on the top of the equipment frame; A first compaction drive module and a second compaction drive module, respectively installed inside the equipment frame; Among them, the first compaction drive module can drive the primary compaction module and the secondary compaction module to synchronously compact the spine of the book core, and the second compaction drive module can drive the tertiary compaction module to compact the entire book core.

[0009] Furthermore, the primary compaction module, the secondary compaction module, and the tertiary compaction module all include: A fixed pressure table, fixedly installed on the upper part of the equipment frame; A movable pressure table, movably installed on the upper part of the equipment frame, capable of moving towards the direction of the fixed pressure table to compact the book core and resetting after compaction.

[0010] Furthermore, the movable pressure table includes: A pedestal, installed on the upper part of the equipment frame; A small pressure plate, slidably arranged on the upper part of the pedestal; A limit runway, in a "U" shape, installed on both sides of the pedestal, with the opening facing the small pressure plate; A plurality of rollers, rotatably connected to both sides of the small pressure plate and rolling inside the limit runway; An inner frame, in a "U" shape, installed inside the small pressure plate; A boss is mounted on the upper part of the pedestal and on a side opposite to the small pressing plate; The first deflection frame and the second deflection frame are rotatably connected between the inner frame and the boss.

[0011] Furthermore, the two sides of the boss are rotationally connected to the No. 2 deflection frame via a convex shaft, the inner side of the inner frame is rotationally connected to the No. 1 deflection frame via a No. 1 connecting rod, and the No. 1 deflection frame and the No. 2 deflection frame are rotationally connected via a No. 2 connecting rod; so that the No. 1 deflection frame and the No. 2 deflection frame as a whole can bulge upward or sink downward after being subjected to force in the middle, forming a "∧" shape or a "∨" shape.

[0012] Furthermore, adjacent ends of the constant pressure platform and the small pressure plate are both installed with protective plates, and the protective plates are made of rubber or silicone.

[0013] Furthermore, when the middle part of the No. 1 deflection frame and the No. 2 deflection frame as a whole is subjected to an upward or downward force, the No. 1 deflection frame and the No. 2 deflection frame as a whole become a "∧" shape or a "∨" shape, and pull the small pressure plate to move toward the direction of the boss, and at the same time the roller rolls inside the limiting runway; when transitioning from the "∧" shape or the "∨" shape to a straight state, the small pressure plate moves away from the boss to compact the book core.

[0014] Furthermore, the first compaction drive module includes: A base, mounted inside the device frame; A bearing seat, mounted inside the equipment frame; A hydraulic cylinder rotatably connected to the upper portion of the base; A linkage shaft, rotatably connected to the interior of the bearing seat; A first swing arm is connected between the telescopic end of the hydraulic cylinder and the linkage shaft rod, the telescopic end of the hydraulic cylinder and the first swing arm are rotationally connected, and the linkage shaft rod and the first swing arm are fixedly connected; A second swing arm, symmetrically fixed on the outside of the linkage shaft; A push-pull rod is rotatably connected to the end of the No. 2 swing arm, and the top end of the push-pull rod is rotatably connected to the No. 2 connecting rod.

[0015] Furthermore, the hydraulic cylinder extends or shortens, driving the linkage shaft, the first swing arm, and the second swing arm to deflect upward or downward as a whole, thereby driving the push-pull rod to move up or down.

[0016] In a second aspect, the present invention further proposes a control system, which is used to control the above-mentioned book block shaping multiple compaction mechanism, comprising: A control unit, for receiving input signals and issuing control instructions; A drive control module, electrically connected to the first compaction drive module and the second compaction drive module, for controlling the actions of the hydraulic cylinder of the first compaction drive module and the drive components of the second compaction drive module according to a control instruction issued by the control unit; A conveying control module, electrically connected to the driving motors of the feed conveyor belt and the discharge conveyor belt, and used to control the start and stop and intermittent conveying of the feed conveyor belt and the discharge conveyor belt according to the control instructions issued by the control unit; The sensor group includes a position sensor and a pressure sensor arranged near the feed conveyor belt, the discharge conveyor belt and the compaction module, and is used to detect the position and compaction pressure of the book block and feed back the detection signal to the control unit.

[0017] Furthermore, it is characterized in that the control unit controls the conveying control module according to the book block position signal fed back by the sensor group so that the feed conveyor belt and the discharge conveyor belt stop conveying when the book block reaches the compaction module position, and continue conveying after the compaction is completed; The control unit controls the drive control module to sequentially drive the first compaction drive module to drive the primary compaction module and the secondary compaction module according to a preset compaction program, so that the dynamic pressure platform moves toward the fixed pressure platform to compact the spine of the book block, and resets after compaction; and drives the second compaction drive module to drive the tertiary compaction module, so that the dynamic pressure platform compacts the entire book block with the help of the large pressure plate; The pressure sensor detects the compaction pressure in real time. When the compaction pressure reaches a preset value, the control unit controls the drive control module to stop the drive component and complete the compaction process. The position sensor is used to detect the position of the book block on the conveyor belt and whether it has reached the correct position of the compaction module. If the position of the book block is abnormal, the control unit sends an alarm signal and controls the conveyor belt to stop running.

[0018] The present invention provides a book block shaping multiple compaction mechanism and system. Compared with the prior art, it has the following beneficial effects: 1. The book core shaping multiple compaction mechanism of the present invention adopts a relay compaction method, and the book core compaction process is divided into three times. Taking actual production as an example, the first compaction module can change the thickness of the book core spine from the initial 10mm to 9mm, the second compaction module further compacts it to 8mm, and the third compaction module uses a large pressing plate to exhaust and compact the entire book core. This gradual compaction method ensures the book pressing effect and also has a protective effect on some large ink books and dictionaries; 2. The pressure sensor in the control system can detect the compaction pressure in real time. When the compaction pressure reaches the preset value, the control unit will promptly control the drive control module to stop the drive components. This precise pressure control method ensures that appropriate pressure can be applied at each compaction stage, and neither insufficient compaction due to too little pressure nor damage to the book core paper due to too much pressure, thus ensuring the quality of book core compaction.

[0019] 3. Compared with the traditional one-time compaction which takes 50 seconds to make the book block reach 6mm thickness, the three-time compaction of the present invention only takes 30 seconds in total. Through phased relay compaction, the time and pressure required for each compaction are relatively small, which greatly shortens the time of a single compaction and improves the production rhythm.

[0020] 4. The compaction mechanism can realize continuous batch processing of book blocks through intermittent conveying of the feed conveyor belt and the discharge conveyor belt during the process of compacting the book blocks by the primary compaction module, the secondary compaction module and the tertiary compaction module at the same time. While a book block is being compacted at a certain stage, a new book block can be moved to the next compaction position, so that the equipment can continue to operate efficiently and meet the needs of large-scale production.

[0021] 5. The control system receives the detection signal of the sensor group through the control unit and automatically issues control instructions according to the preset program. The drive control module accurately controls the actions of the first compaction drive module and the second compaction drive module according to the instructions, and the conveying control module is responsible for the start and stop and intermittent conveying of the feed conveyor belt and the discharge conveyor belt. The entire compaction process is automated, reducing manual intervention and improving the accuracy and stability of production.

[0022] 6. The position sensor in the sensor group can detect the position of the book core on the conveyor belt and whether it has reached the correct position of the compaction module in real time. When the position of the book core is abnormal, the control unit will send out an alarm signal and control the conveyor belt to stop running, avoiding the compaction position deviation problem caused by the book core position deviation. At the same time, the conveying control module can accurately control the start and stop and intermittent conveying of the conveyor belt according to the position and compaction status of the book core, ensuring that the book core remains stable during the compaction process, further improving the stability and reliability of the equipment.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0026] See also Figure 1-5 The present invention provides a technical solution: a book block shaping multiple compaction mechanism, comprising an equipment frame 1, a feeding conveyor belt 2 and a discharging conveyor belt 3 are respectively installed on both sides of the equipment frame 1, the conveying end of the feeding conveyor belt 2 and the conveying start of the discharging conveyor belt 3 both extend toward the inside of the equipment frame 1, and the two are connected to each other, a primary compaction module 4, a secondary compaction module 5, and a tertiary compaction module 6 are respectively installed on the top of the equipment frame 1, a first compaction drive module 7 and a second compaction drive module 8 are respectively installed inside the equipment frame 1, the first compaction drive module 7 can drive the primary compaction module 4 and the secondary compaction module 5 to compact the spine of the book block synchronously, and the second compaction drive module 8 can drive the tertiary compaction module 6 to compact the entire book block; The primary compaction module 4, the secondary compaction module 5, and the tertiary compaction module 6 all include a fixed-pressure table 51 and a moving-pressure table 52 installed on the upper part of the equipment frame 1. The fixed-pressure table 51 is set to be stationary, while the moving-pressure table 52 can move towards the fixed-pressure table 51 to compact the book core. After compaction, the moving-pressure table 52 can reset; The moving-pressure table 52 includes a pedestal 521 installed on the upper part of the equipment frame 1. A small pressing plate 522 is slidably arranged on the upper part of the pedestal 521. "U"-shaped limiting runways 523 are installed on both sides of the pedestal 521. A plurality of rollers 524 are rotatably connected to both sides of the small pressing plate 522. The openings of the limiting runways 523 face the small pressing plate 522, and a plurality of rollers 524 all roll inside the limiting runways 523. An inner frame 525 with a "U" shape is installed on the inner side of the small pressing plate 522. On the upper part of the pedestal 521 and on the side opposite to the small pressing plate 522, a convex platform 526 is installed. A first deflecting frame 527 and a second deflecting frame 528 are rotatably connected between the inner frame 525 and the convex platform 526; The two sides of the convex platform 526 and the second deflecting frame 528 are rotatably connected through a convex shaft 529. The inner side of the inner frame 525 and the first deflecting frame 527 are rotatably connected through a first connecting rod 5210. The first deflecting frame 527 and the second deflecting frame 528 are rotatably connected through a second connecting rod 5211; such that the whole of the first deflecting frame 527 and the second deflecting frame 528 can bulge upward or sink downward in the middle after being stressed in the middle, that is, the whole of the first deflecting frame 527 and the second deflecting frame 528 will form a "∧" shape or a "∨" shape after being stressed in the middle; Protective plates 5212 are installed at the adjacent ends of the fixed-pressure table 51 and the small pressing plate 522. The protective plates 5212 are preferably made of rubber or silica gel and can protect the pressed parts of the books; When the moving-pressure table 52 is working, if an upward pushing or downward pulling force is applied to the middle of the whole of the first deflecting frame 527 and the second deflecting frame 528, then the whole of the first deflecting frame 527 and the second deflecting frame 528 will become a "∧" shape or a "∨" shape. During this process, the small pressing plate 522 will be pulled to move towards the convex platform 526, and at the same time, the rollers 524 roll inside the limiting runways 523. Only when transitioning from a "∧" shape or a "∨" shape to a straight state, the small pressing plate 522 will move away from the convex platform 526, that is, the book core is compacted; The first compaction drive module 7 includes a base 71 and a bearing seat 72 installed inside the equipment frame 1. The upper part of the base 71 is rotatably connected to the hydraulic cylinder 73. The inside of the bearing seat 72 is rotatably connected to the linkage shaft 74. The telescopic end of the hydraulic cylinder 73 and the linkage shaft 74 are commonly connected to a No. 1 swing arm 75. The telescopic end of the hydraulic cylinder 73 is rotatably connected to the No. 1 swing arm 75. The linkage shaft 74 is fixedly connected to the No. 1 swing arm 75. The outside of the linkage shaft 74 is also symmetrically fixed to a No. 2 swing arm 76. The end of the No. 2 swing arm 76 is rotatably connected to a push-pull rod 77. The top of the push-pull rod 77 is rotatably connected to the No. 2 connecting rod 5211. When the first compaction drive module 7 is working, the hydraulic cylinder 73 extends or shortens, driving the linkage shaft 74, the first swing arm 75, and the second swing arm 76 to deflect upward or downward as a whole, thereby driving the push-pull rod 77 to push up or sink.

[0027] The first compaction drive module 7 and the second compaction drive module 8 have the same principle and similar structure. The specific difference is that the first compaction drive module 7 needs two driving ends to be connected to the dynamic pressure platform 52 of the primary compaction module 4 and the secondary compaction module 5 respectively, while the second compaction drive module 8 only needs one driving end to be connected to the tertiary compaction module 6 and the dynamic pressure platform 52. Therefore, the first compaction drive module 7 is provided with two push-pull rods 77, while the second compaction drive module 8 only needs one push-pull rod 77. In addition, because the primary compaction module 4 and the secondary compaction module 5 only need to compact the spine of the book core, and the tertiary compaction module 6 needs to compact the entire book core, the primary compaction module 4 and the secondary compaction module 5 are only provided with a small pressing plate 522 adapted to the area of ​​the spine of the book core, and in the tertiary compaction module 6, a large pressing plate 9 needs to be provided at the adjacent ends of the fixed pressure platform 51 and the dynamic pressure platform 52, and the area of ​​the large pressing plate 9 is larger than the area of ​​the entire book core, so the entire book core can be compacted; In order to prevent the book block from tilting when compacting the spine, a conveying limit guardrail 10 is set just above the primary compacting module 4 and the secondary compacting module 5. However, because of the large pressing plate 9 of the tertiary compacting module 6, the conveying limit guardrail 10 does not need to extend to just above the tertiary compacting module 6; The conveying sections of the feed conveyor belt 2 and the discharge conveyor belt 3 are both located below the small pressure plate 522, and the feed conveyor belt 2 and the discharge conveyor belt 3 can intermittently convey the book core, so that the book core can be compacted in cooperation with the primary compaction module 4, the secondary compaction module 5, and the tertiary compaction module 6. That is to say, in the process of the primary compaction module 4, the secondary compaction module 5, and the tertiary compaction module 6 compacting the book core at the same time, the feed conveyor belt 2 and the discharge conveyor belt 3 are in a stopped state, and after the compaction is completed, the feed conveyor belt 2 and the discharge conveyor belt 3 continue to convey the book core; When the compacting mechanism is working, the book core to be compacted is conveyed by the feed conveyor belt 2. When the book core is conveyed to the position of the primary compacting module 4, the first compacting driving module 7 drives the dynamic pressure platform 52 of the primary compacting module 4 to move toward the fixed pressure platform 51, until the fixed pressure platform 51 and the dynamic pressure platform 52 compact the spine of the book core together. Then, the first compacting driving module 7 drives the dynamic pressure platform 52 of the primary compacting module 4 away from the fixed pressure platform 51, and then the book core after the first compaction continues to follow the feed conveyor belt 2 to move to the position of the secondary compacting module 5. At this time, the new book core will also move to the position of the primary compacting module 4. At this time, the first compacting driving module 7 drives the dynamic pressure platform 52 of the primary compacting module 4 to move away from the fixed pressure platform 51. The movable module 7 drives the primary compaction module 4 and the secondary compaction module 5 to perform the first and second compaction treatments on the book core respectively. After the second compaction, the book core is conveyed by the feed conveyor belt 2 to the discharge conveyor belt 3 and arrives at the position of the tertiary compaction module 6. At the same time, the book core originally at the position of the primary compaction module 4 will also move to the secondary compaction module 5. This reciprocating process can be used to compact the book core in batches. During the compaction process of the tertiary compaction module 6, the second compaction driving module 8 drives the tertiary compaction module 6, and then uses the large pressing plate 9 to compact the entire book core. After compaction, it is output through the discharge conveyor belt 3. The reason for compacting the book core three times is that if the book core is compacted in place at one time, the compaction effect is not good and time is wasted. Now a book core is compacted three times. For example, the first compaction of the primary compaction module 4 can make the thickness of the book core spine become 9mm, and the second compaction of the secondary compaction module 5 can make the thickness of the book core spine become 8mm. Similarly, the third compaction of the tertiary compaction module 6 can exhaust the entire book core. The disadvantage of compacting in place at one time is that excessive pressure may damage the ink of the pattern inside the book, and low pressure cannot achieve the ideal effect. It takes a long time to achieve the ideal effect. Therefore, the relay compaction method of the book core is not only efficient, but also has a better compaction effect. Example 2

[0028] See also Figure 6 , a control system, which is used to control the book block shaping multiple compaction mechanism of embodiment 1, comprising: A control unit 11, for receiving input signals and issuing control instructions; The drive control module 12 is electrically connected to the first compaction drive module 7 and the second compaction drive module 8, and is used to control the hydraulic cylinder 73 of the first compaction drive module 7 and the drive components of the second compaction drive module 8 according to the control instructions issued by the control unit 11; The conveying control module 13 is electrically connected to the driving motors of the feed conveyor belt 2 and the discharge conveyor belt 3, and is used to control the start and stop and intermittent conveying of the feed conveyor belt 2 and the discharge conveyor belt 3 according to the control instructions issued by the control unit 11; The sensor group 14 includes position sensors and pressure sensors arranged near the feed conveyor belt 2 , the discharge conveyor belt 3 and the compaction module, and is used to detect the position and compaction pressure of the book block and feed back the detection signal to the control unit 11 .

[0029] Further, it is characterized in that the control unit 11 controls the conveying control module 13 to make the feeding conveyor belt 2 and the discharging conveyor belt 3 stop conveying when the book block reaches the compaction module position according to the book block position signal fed back by the sensor group 14, and continue conveying after the compaction is completed; The control unit 11 controls the driving control module 12 to sequentially drive the first compaction driving module 7 to drive the primary compaction module 4 and the secondary compaction module 5 according to the preset compaction program, so that the dynamic pressure table 52 moves toward the fixed pressure table 51 to compact the spine of the book block and resets after compaction; and drives the second compaction driving module 8 to drive the tertiary compaction module 6, so that the dynamic pressure table 52 compacts the entire book block with the help of the large pressure plate 9; The pressure sensor detects the compaction pressure in real time. When the compaction pressure reaches a preset value, the control unit 11 controls the drive control module 12 to stop the drive component and complete the compaction process. The position sensor is used to detect the position of the book block on the conveyor belt and whether it has reached the correct position of the compaction module. If the position of the book block is abnormal, the control unit 11 sends an alarm signal and controls the conveyor belt to stop running.
