Description

Technical Field

[0001] This utility model relates to a printing device, specifically a book edge printing machine. Background Technology

[0002] When printing a book, the edges of the book block are usually cut to the original color of the paper. To further enhance the appearance of the edges, techniques such as gold trim and full-page colored edges were later developed. To print patterns and designs on the edges, a common method is edge overprinting, where different colors are applied to the edges to create colorful patterns. Alternatively, existing UV digital inkjet printing can be modified for color printing of the edges.

[0003] Existing book edge printing machines use the spine as the positioning surface for printing book edges. However, when printing the edges of multiple book blocks of different heights simultaneously, the unevenness of the printing surface can easily lead to unstable and inconsistent printing quality, severely affecting the overall quality of the book edge printing. Therefore, Chinese utility model application CN111572213A provides a book edge printing device, which effectively solves the problem of unstable printing quality when printing multiple books simultaneously. However, this device still has the following drawbacks:

[0004] 1. When placing large books, the rotating mechanism located in the center will interfere with the books, making it impossible to print these large books.

[0005] 2. To avoid this interference, the diameter of the turntable needs to be designed to be larger. However, a larger diameter leads to greater centrifugal force, which has an adverse effect on the secure installation of the equipment. In addition, the power output will also increase significantly. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a book edge printing machine, aiming to at least partially solve one of the technical problems in the prior art.

[0007] The book edge printing machine according to this utility model includes a turntable driven by a power unit and a multi-station clamping assembly mounted on the turntable. The multi-station clamping assembly includes a chassis and multiple clamping assemblies connected to the chassis, with the multiple clamping assemblies distributed around the center of the chassis. Each clamping assembly includes a fixed clamping plate, a push plate, and a linear drive mechanism. The fixed clamping plate is perpendicular to and fixedly connected to the chassis. The push plate is parallel to the fixed clamping plate. The center of the chassis is located on the same side of the plane where the fixed clamping plate is located and the plane where the push plate is located. The plane where the push plate is located is closer to the center of the chassis than the plane where the fixed clamping plate is located. The push plate is located between the linear drive mechanism and the fixed clamping plate. The linear drive mechanism is close to the edge of the chassis and connected to the push plate. The linear drive mechanism can drive the push plate away from or towards the fixed clamping plate.

[0008] In some embodiments, the chassis includes four base plates, each base plate having a clamping assembly; the base plates are L-shaped and include connecting portions and cantilever portions, the four connecting portions are distributed around the center of the base plates and adjacent connecting portions are connected to each other, a fixed clamping plate is fixedly connected to the connecting portions, and a linear drive mechanism is provided on the cantilever portion.

[0009] In some embodiments, the connecting portion is provided with a plurality of elongated holes, at least some of which are located between the fixing clamp and the push plate.

[0010] In some embodiments, a bridging plate is provided at the end of the connecting portion away from the cantilever portion, and the bridging plate is detachably connected to the adjacent connecting portion by fasteners.

[0011] In some embodiments, the multi-station fixture assembly further includes transverse reinforcing ribs and longitudinal reinforcing ribs connected to the base plate. The transverse reinforcing ribs and the linear drive mechanism are located on opposite sides of the base plate, and the longitudinal reinforcing ribs and the transverse reinforcing ribs are located on the same side of the base plate and perpendicular to each other.

[0012] In some embodiments, the linear drive mechanism includes a mounting plate, a linear module, and a connector. The mounting plate is fixedly connected to the chassis, the linear module is disposed on the mounting plate, one end of the connector is connected to the push plate, and the other end of the connector is connected to the linear module.

[0013] In some embodiments, the linear drive mechanism further includes a first slide rail and a second slide rail that are parallel to each other. A slider is provided on both the first slide rail and the second slide rail. Both the first slide rail and the second slide rail are connected to the mounting plate. The linear module is located between the first slide rail and the second slide rail. The connector is connected to the slider.

[0014] In some embodiments, the linear drive mechanism further includes a first side plate and a second side plate that are parallel to each other, and the first slide rail, the linear module and the second slide rail are both located between the first side plate and the second side plate. The first side plate and the second side plate are both fixedly connected to the connector and / or the slider.

[0015] In some embodiments, the clamping assembly further includes a grating ruler sensor, which is fixedly connected to the chassis and used to measure the displacement of the push plate.

[0016] Compared with existing technologies, this invention optimizes the layout of the push plate and the fixed clamping plate. This optimization reduces the overall size of the multi-station fixture assembly by approximately 25%, significantly improving space utilization and facilitating equipment miniaturization. Furthermore, the space between the push plate and the fixed clamping plate for placing books can be fully utilized, no longer constrained by the rotating mechanism. This multi-station fixture assembly can be used for printing larger books. Attached Figure Description

[0034] Figure 1 In the illustrated embodiment, the multi-station fixture assembly of this utility model includes a chassis 100 and four clamping assemblies 200 connected to the chassis 100. The four clamping assemblies 200 are distributed around the center of the chassis 100, as shown below. Figure 1 As shown in the figure, point O is the center of chassis 100. The clamping assembly 200 includes a fixed clamping plate 2, a push plate 3, and a linear drive mechanism 4. The fixed clamping plate 2 is perpendicular to chassis 100 and can be integrally formed with chassis 100 or fixedly connected to chassis 100 by fasteners. To enhance the deformation resistance of the fixed clamping plate 2, a rib can be provided on the side of the fixed clamping plate 2 opposite to the push plate 3. The push plate 3 is parallel to the fixed clamping plate 2, and the center of chassis 100 is located on the same side of the plane containing both the fixed clamping plate 2 and the plane containing the push plate 3. The plane containing the push plate 3 is closer to the center of chassis 100 than the plane containing the fixed clamping plate 2. Figure 1 As shown, a space for placing books 13 is formed between the fixed clamping plate 2 and the push plate 3. This space extends toward the center of the turntable 9, avoiding the center hole of the chassis 100, allowing the height of this book-placing space to exceed the height of the center O. The push plate 3 is driven by the linear drive mechanism 4 to reciprocate relative to the fixed clamping plate 2.

[0035] In this utility model, it can be a single, integral piece. Figure 1 In the illustrated embodiment, the chassis 100 is composed of four base plates 1 connected together, each base plate 1 having a clamping assembly 200. The base plates 1 are cut from sheet metal and are L-shaped along the front view direction. Each base plate 1 includes interconnected connecting portions 101 and cantilever portions 102. The four base plates 1 have a total of four connecting portions 101, which are distributed around the center of each base plate 1, and adjacent connecting portions 101 are interconnected. A fixing clamp 2 is bolted to the connecting portions 101, and a linear drive mechanism 4 is mounted on the cantilever portion 102. The multi-station clamping assembly in this embodiment is easy to manufacture.

[0036] like Figure 2 and 3As shown, the base plate 1 has a plurality of elongated holes 1011, at least some of which are located in the connecting portion 101. These elongated holes 1011 reduce the weight of the chassis 100 while ensuring that the base plate 1 has the required structural strength.

[0037] like Figure 3 and 5 As shown, a bridging plate 5 is provided at the end of the connecting part 101 away from the cantilever part 102. The bridging plate 5 is detachably connected to the adjacent connecting part 101 by fasteners. Each connecting part 101 is provided with two bridging plates 5 at the end away from the cantilever part 102, and the connecting parts 101 on two adjacent base plates 1 are connected by the two bridging plates 5.

[0038] like Figures 4 to 6 As shown, the back side of the base plate 1 is provided with a transverse reinforcing rib 6 and a longitudinal reinforcing rib 7. The transverse reinforcing rib 6 is located on the opposite side of the linear drive mechanism 4, and the longitudinal reinforcing rib 7 is located on the same side of the base plate 1 and perpendicular to each other. The linear drive mechanism 4, the push plate 3, and the fixing clamp 2 are all located on the front side of the base plate 1, and the transverse reinforcing rib 6 and the longitudinal reinforcing rib 7 are all located on the rear side of the base plate 1. The transverse reinforcing rib 6 and the longitudinal reinforcing rib 7 can improve the structural strength of the base plate 1. Several through holes can also be provided in the reinforcing ribs, through which fasteners connect the chassis 100 and the turntable 9, which can provide a stronger locking force.

[0039] In this invention, the linear drive mechanism 4 includes a mounting plate 401, a linear module 402, and a connecting member 403. The mounting plate 401 can be made from a sheet metal, perpendicular to the chassis 100, and fixedly connected to the chassis 100 by bolts; alternatively, it can be integrally formed. The linear module 402 is mounted on the mounting plate 401. One end of the connecting member 403 is connected to the push plate 3, and the other end is connected to the linear module 402. The linear module 402 drives the connecting member 403 to move, thereby causing the push plate 3 to move. Figure 5 As shown, the linear module 402 consists of a motor 4021, a coupling 4022, a lead screw 4023, a first bearing housing 4024, a second bearing housing 4025, and a slide 4026. Both the first and second bearing housings 4024 and 4025 are mounted on a mounting plate 401. One end of the lead screw 4023 is rotatably connected to the first bearing housing 4024, and the other end is rotatably connected to the second bearing housing 4025. The slide 4026 is mounted on the lead screw 4023. The motor 4021 is connected to the mounting plate 401 and / or the base plate 1 via a bracket. The lead screw 4023 is connected to the shaft of the motor 4021 via the coupling 4022. The connecting piece 403 is fixedly connected to the slide 4026 by bolts. When the motor 4021 drives the lead screw 4023 to rotate, the slide 4026 slides on the lead screw 4023, thereby moving the connecting piece 403.

[0040] See Figure 5 As shown, the linear drive mechanism 4 also includes a first slide rail 404 and a second slide rail 405 that are parallel to each other. A slider 406 is provided on both the first slide rail 404 and the second slide rail 405. Both the first slide rail 404 and the second slide rail 405 are connected to the mounting plate 401. The linear module 402 is located between the first slide rail 404 and the second slide rail 405. The connecting piece 403 is connected to the slider 406. The stability of the push plate 3 when it moves can be improved by setting the first slide rail 404 and the second slide rail 405.

[0041] See Figure 5 As shown, the linear drive mechanism 4 also includes a first side sealing plate 407 and a second side sealing plate 408 that are parallel to each other. The first slide rail 404, the linear module 402, and the second slide rail 405 are all located between the first side sealing plate 407 and the second side sealing plate 408. The first side sealing plate 407 and the second side sealing plate 408 are both fixedly connected to the connecting member 403 and / or the slider 406. Figure 2 As shown, the first slide rail 404, the second slide rail 405 and the linear module 402 are enclosed in a closed space composed of the connector 403, the first side sealing plate 407 and the second side sealing plate 408. This can effectively prevent dust from adhering to the first slide rail 404, the second slide rail 405 and the lead screw 4023, which helps to extend the service life of the equipment and reduce maintenance costs.

[0042] See Figure 5 As shown, the clamping assembly 200 also includes a grating ruler sensor 8, which is fixedly connected to the chassis 100 and used to measure the displacement of the push plate 3. The aforementioned grating ruler sensor 8 can also be replaced by other distance measuring sensors.

[0043] See Figure 7 As shown, the chassis 100 is perpendicular to the horizontal plane. The rear of the chassis 100 is fixed to the turntable 9, which drives the chassis 100 to rotate. Around the chassis 100, in a counter-clockwise direction, are arranged a lifting platform 10, a cleaning device 11, and a printing device 12, with the lifting platform 10 located below the chassis 100. See again. Figure 7 At this point, the positions of the four clamping components 200 in the figure correspond to the four stations in the book edge printing process. The position of the bottom clamping component 200 is the material feeding station. The positions of the other three clamping components 200 along the counterclockwise direction are the cleaning station, the printing station, and the unloading station, respectively. Each time the chassis 100 rotates 90 degrees counterclockwise, the clamping component 200 can move to the next station.

[0044] The working process of the material unloading station is as follows: First, the lifting platform 10 rises a certain distance, and then the books 13 to be printed are placed between the push plate 3 and the fixed clamping plate 2, with the edge of the book to be printed facing the lifting platform 10. Under the action of gravity, the lower end of the book falls on the lifting platform 10. The lifting platform 10 can ensure that the edges of multiple books are aligned. Then, the linear drive mechanism 4 pushes the push plate 3 toward the fixed clamping plate 2 until the book 13 is stably clamped between the push plate 3 and the fixed clamping plate 2. Finally, the lifting platform 10 descends and returns to its original position. By lowering the lifting platform 10, it is prevented that the multi-station fixture assembly will collide with the lifting platform 10 during operation.

[0045] The cleaning station works as follows: The cleaning device 11 cleans the printing surface of the books to ensure that the printing surface is clean.

[0046] The working process of the printing station: The printing device 12 prints the required pattern on the edge of the book.

[0047] The unloading station works as follows: The linear drive mechanism 4 drives the push plate 3 away from the fixed clamping plate 2. Under the action of gravity, the books are stably stacked on the fixed clamping plate 2. Finally, the printed books can be removed by a robotic arm or manually.

[0048] Compared with the prior art, this utility model optimizes the layout of the push plate 3 and the fixed clamping plate 2 on the chassis 100, so that the book placement space is offset from the center of the chassis 100. This allows the diameter of the multi-station clamping assembly to be significantly reduced while maintaining the same book placement space, which is conducive to the miniaturization of the equipment and also greatly reduces the centrifugal force and power consumption during equipment operation.

[0049] In other aspects of the above embodiments, the device of this utility model has the advantages of being easy to manufacture, assemble, and securely assembled.
