Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and specifically relates to a binding device for printed publications. Background Technology

[0002] Perfect binding is the process of using adhesives to hold the pages of printed materials together and bond them to the cover to form a complete book, magazine, etc. During perfect binding, paper needs to be cut to the required size and shape, and then the cut sheets are arranged neatly according to the designed layout, ensuring even spacing. A suitable amount of adhesive is then evenly applied to the spine. The glued paper is then heated and pressed to completely bond it together. Finally, the bonded paper is hot-pressed to form a complete printed product, and then trimmed according to the finished size. However, in actual processing, existing perfect binding equipment cannot provide sufficient clamping force to ensure tightness. Furthermore, in continuous perfect binding processes, existing equipment has a slow response rate, making it unable to quickly press or detach from the book.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a pressing device for perfect binding production in book printing [202420373260.2], which includes a base plate; a back plate, the back plate being fixedly installed on top of the base plate; a conveyor belt, the conveyor belt being disposed on the base plate; multiple positioning boxes, the multiple positioning boxes being disposed on the conveyor belt; a perfect bound book, the perfect bound book being disposed on the positioning boxes; a displacement mechanism, the displacement mechanism being disposed on the back plate, the displacement mechanism being used to drive the pressing mechanism to move; and a pressing mechanism, the pressing mechanism being disposed on the displacement mechanism, the pressing mechanism being used to press the perfect bound book.

[0004] The above solution has solved the problem of insufficient clamping force in adhesive binding equipment to some extent, but it still has many shortcomings, such as slow response rate. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a reasonably designed and fast-responding threading and binding device for printed publications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a printing publication thread binding device, comprising a pair of vertically adjacent pressing strips, an adjusting component between the pressing strips, a pressing roller rotatably mounted on the opposite side of the pressing strips, an electric opening and closing component between the pressing roller and the pressing strips, and a transfer component on the pressing strips.

[0007] In the above-mentioned printing publication thread binding device, the pressing strip is made of stainless steel. An installation groove is opened on the opposite side of the pressing strip for the pressing roller to be inserted. Movable blocks are slidably installed at both ends inside the installation groove. The pressing roller is rotatably installed between the movable blocks. A support rod is connected between the movable blocks. An electric opening and closing component is installed between the support rod and the pressing strip.

[0008] In the above-mentioned printing publication thread binding device, the electric opening and closing component includes an electric push rod installed inside the pressing strip, a push block connected to the telescopic end of the electric push rod, a linkage block installed on the support rod, and a guide slope that fits between the push block and the linkage block.

[0009] In the above-mentioned thread binding device for printed publications, the linkage block is slidably connected to the support rod, and a buffer spring is sleeved on the support rod, which is connected to the linkage block.

[0010] In the above-mentioned thread binding device for printed publications, an elastic reset element is installed between the movable block and the mounting groove.

[0011] In the above-mentioned printing publication thread binding device, the spacing adjustment component includes a spacing adjustment screw movably connected to the pressing bar, and a spacing adjustment knob is installed on the pressing bar. The spacing adjustment knob is driven by the adjusting screw through a speed change gear set.

[0012] In the above-mentioned printing publication thread binding device, the adapter component includes an adapter hole provided at the upper end of the pressing bar, an adapter seat inserted into the inner side of the adapter hole, and a quick-release component provided between the pressing bar and the adapter seat.

[0013] In the above-mentioned printing publication thread binding device, the upper end of the adapter is provided with an adapter tube, the adapter tube has adapter grooves arranged in a centrally symmetrical manner, the inner side of the adapter groove is provided with an adapter buckle, and the side of the adapter tube has adapter interfaces arranged in a centrally symmetrical manner.

[0014] In the above-mentioned printing publication thread binding device, the quick-release component includes a limiting strip disposed inside the adapter hole, and a limiting groove is left between the limiting strips for the limiting head at the lower end of the adapter to be inserted. The limiting head rotates and fits against the lower end of the limiting strip. The limiting head is in a plum blossom shape, and a repulsive magnet is disposed between the limiting head and the bottom of the adapter hole.

[0015] In the above-mentioned binding device for printed publications, the outer side of the pressing roller is covered with a piezoelectric film.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: the pressing roller is quickly clamped or separated under the action of the electric opening and closing component, which improves the response rate of the binding device and facilitates continuous binding operations; the transfer component facilitates the rapid connection between the pressing strip and the binding system, thereby adjusting the specifications of the pressing strip and the internal pressing roller in a timely manner to adapt to the binding needs of different publications; the pressing roller surface is covered with a piezoelectric film, thereby detecting the clamping force in a timely manner and ensuring the stability of the publication.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a binding device for printed publications includes a pair of vertically adjacent pressing strips 1. An adjusting component 2 is provided between the pressing strips 1 to adjust their maximum relative distance. A pressing roller 3 is rotatably mounted on the opposite side of the pressing strips 1. An electrically operated opening and closing component 4 is provided between the pressing roller 3 and the pressing strips 1. A transfer component 5 is provided on the pressing strips 1. The electrically operated opening and closing component 4 provides rapid response adjustment to the pressing roller 3, ensuring that the pressing roller 3 can quickly press against the publication. The transfer component 5 allows for the overall specification switching of the pressing strips 1 as needed.

[0024] Specifically, similar to conventional pressing structures, the pressing strip 1 in this embodiment is made of stainless steel. An installation groove 6 is provided on one side of the pressing strip 1 for the pressing roller 3 to be inserted. Movable blocks 7 are slidably installed at both ends inside the installation groove 6. The pressing roller 3 is rotatably mounted between the movable blocks 7. A support rod 8 connects the movable blocks 7 to ensure synchronous lifting and lowering of the movable blocks 7. An electric opening and closing assembly 4 is installed between the support rod 8 and the pressing strip 1. The central axis of the pressing roller 3 is parallel to the support rod 8, and the electric opening and closing assembly 4 provides sufficient driving force to the support rod 8.

[0025] Furthermore, to further improve the response rate, the electric opening and closing assembly 4 includes an electric push rod 41 installed inside the pressing strip 1. The telescopic end of the electric push rod 41 is connected to a push block 42, and a linkage block 43 is installed on the support rod 8. A guide ramp 44 that fits between the push block 42 and the linkage block 43 is provided. When the electric push rod 41 drives the push block 42 to slide, the guide ramp 44 between the linkage block 43 also comes into contact, thereby driving the linkage block 43 and the support rod 8 to move as a whole.

[0026] Furthermore, to achieve compression and buffering, the linkage block 43 is slidably connected to the support rod 8, and a buffer spring 9 is sleeved on the support rod 8, which is connected to the linkage block 43. When the linkage block 43 is compressed, it slides along the support rod 8 until the buffer spring 9 is fully compressed, at which point the pressing roller 3 moves closer.

[0027] Furthermore, a resilient reset element is installed between the movable block 7 and the mounting groove 6. When the electric push rod 41 resets, the resilient reset element applies a top pressure to the movable block 7, causing the pressing roller 3 between the movable blocks 7 to separate.

[0028] In addition, the adjusting assembly 2 includes an adjusting screw 21 that is movably connected to the pressing bar 1. An adjusting knob 22 is installed on the pressing bar 1. The adjusting knob 22 is driven by the adjusting screw 21 through a gear set. The rotation of the adjusting knob 22 drives the adjusting screw 21 to rotate. The gear set enables the adjusting screws 21 at both ends of the pressing bar 1 to rotate synchronously, thereby ensuring that the pressing roller 3 always remains parallel.

[0029] Meanwhile, unlike conventional threaded adapter structures, the adapter component 5 in this embodiment adopts a quick-release structure, specifically including an adapter hole 51 located at the upper end of the pressing strip 1, an adapter seat 52 inserted into the inner side of the adapter hole 51, and a quick-release component between the pressing strip 1 and the adapter seat 52. The adapter seat 52 can be quickly replaced through the quick-release component, thereby enabling the adapter to be connected to different pressing strips 1.

[0030] As can be seen, the upper end of the adapter 52 is provided with an adapter cylinder 53, the adapter cylinder 53 has adapter grooves 54 arranged in a centrally symmetrical manner, the inner side of the adapter grooves 54 is provided with an adapter buckle 55, and the side of the adapter cylinder 53 has adapter interfaces 56 arranged in a centrally symmetrical manner. The upper end of the adapter 52 is provided with a toothed structure, which can simultaneously achieve circumferential and axial limiting.

[0031] Clearly, the quick-release assembly includes a limiting strip 57 located inside the adapter hole 51. Limiting grooves 59 are provided between the limiting strips 57 for the limiting head 58 at the lower end of the adapter seat 52 to insert into. The limiting head 58 rotates and fits against the lower end of the limiting strip 57. The limiting head 58 is shaped like a quincunx, and a repulsive magnet is provided between the limiting head 58 and the bottom of the adapter hole 51. Magnetic repulsion provides sufficient pushing force to the limiting head 58, ensuring a tight fit between the limiting head 58 and the limiting strip 57. When separation is required, simply rotating the adapter seat 52 will release the assembly.

[0032] Preferably, the outer side of the pressing roller 3 is covered with a piezoelectric film, and the clamping force of the pressing roller 3 is controlled by negative feedback adjustment. The piezoelectric film also adapts to the rolling of the pressing roller 3, which facilitates continuous monitoring of the clamping force.

[0033] In summary, the principle of this embodiment is as follows: the relative distance between the pressing strips 1 is limited by the adjusting component 2, and the pressing rollers 3 between them move closer or further apart under the drive of the electric opening and closing component 4, thereby applying sufficient fixing force to the publication, and achieving continuous clamping operation through rolling transmission and opening and closing motion.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as pressing strip 1, adjusting assembly 2, adjusting screw 21, adjusting knob 22, pressing roller 3, electric opening and closing assembly 4, electric push rod 41, pushing block 42, linkage block 43, guide slope 44, adapter assembly 5, adapter hole 51, adapter seat 52, adapter cylinder 53, adapter groove 54, adapter buckle 55, adapter interface 56, limiting strip 57, limiting head 58, limiting groove 59, mounting groove 6, movable block 7, support rod 8, and buffer spring 9, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
