Description

Technical Field

[0001] This utility model relates to the field of printing and binding equipment, and in particular to a dual-module collaborative book feeding mechanism for perfect binding machines. Background Technology

[0002] In the printing and binding industry, perfect binding machines are the core equipment for book and magazine binding. The efficiency and stability of their book feeding mechanism directly determine the overall production capacity and finished product quality of the production line.

[0003] A search of Chinese patents revealed publication number CN209552750U, which discloses an automatic book feeding mechanism for a spine gluing machine. The mechanism includes a frame with a book block conveying track, a book block spacing device, and a spacing ejection unit. The book block spacing device surrounds the outer periphery of the book block conveying track and includes a conveyor chain, a conveyor chain drive unit that drives the conveyor chain to rotate, and spacing units fixedly mounted on the conveyor chain. The book block conveying track continuously transports book blocks forward. Simultaneously, the conveyor chain drive unit drives the conveyor chain and the spacing units to rotate. Each time a book block passes by, the spacing ejection unit ejects the spacing unit, separating each book block. This invention separates each book block and ensures that each book block is neatly arranged, thus guaranteeing both production quality and efficiency.

[0004] Currently, most perfect binding machines on the market use a single-sided, single-module book feeding mechanism, which has a significant drawback: its operational efficiency is severely limited. Traditional single-sided feeding mechanisms can only transport and position one set of books at a time. There is a long idle waiting time between the feeding and handover to the next process, limiting the number of books the machine can process per unit time. This makes it difficult to meet the high-speed production demands of the modern printing industry, especially in mass production scenarios where the low production efficiency is even more pronounced. To address these issues, we propose a dual-module collaborative book feeding mechanism for perfect binding machines. Utility Model Content

[0005] The purpose of this invention is to provide a dual-module collaborative book feeding mechanism for perfect binding machines, which has the advantage of high book feeding efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A dual-module collaborative book-feeding mechanism for a perfect binding machine includes a fixed frame, a reducer bolted to the inner wall of the fixed frame, a first motor bolted to the surface of the reducer, a first rotating shaft bolted to the output end of the reducer, and the first rotating shaft rotatably sleeved with the inner wall of the fixed frame, a first sprocket fixedly sleeved on the surface of the first rotating shaft, a second rotating shaft rotatably sleeved between the inner walls of the fixed frame, and a second sprocket fixedly sleeved on the surface of the second rotating shaft, the surfaces of the first sprocket and the second sprocket transmitting power... The device is connected by a chain. Both ends of the second rotating shaft are fixedly sleeved with turntables. The surface of each turntable is provided with a transmission mechanism. The other end of each transmission mechanism is provided with a swing arm and a transmission rod. The swing arm is rotatably connected to the surface of the fixed frame. The other end of the transmission rod is bolted with a swing rod. The inner wall of the swing rod is fixedly sleeved with a third rotating shaft. The third rotating shaft is rotatably sleeved with the inner wall of the fixed frame. The other end of the swing arm and the swing rod is provided with an adjustment mechanism. The surface of the adjustment mechanism is provided with a book support arm. The inside of the fixed frame is equipped with a grid plate, and the grid plate and the book support arm are connected through each other.

[0007] By adopting the above technical solution, the coaxial drive transmission system drives the inner and outer book feeding modules to perform alternating phase drive, which improves the working efficiency by more than 40% compared with the traditional single-sided book feeding mechanism, and realizes zero-speed handover control of book transfer, thus improving the efficiency of book feeding. Each book support arm is equipped with a second motor, which can handle books with real-time changes in spine height to achieve diversified production.

[0008] The present invention is further configured such that: the transmission mechanism includes a first connecting rod, one end of the first connecting rod is rotatably connected to the surface of the turntable, and a second connecting rod is rotatably connected to both the surface of the swing arm and the surface of the transmission rod, and an adjusting screw is threadedly connected to the inner wall of the second connecting rod and the first connecting rod.

[0009] By adopting the above technical solution and setting up a transmission mechanism, the length can be adjusted, thus improving applicability.

[0010] The present invention is further configured such that: the adjustment mechanism includes two fixed seats, the surfaces of the two fixed seats are rotatably connected to one end of the swing arm and the transmission rod respectively, and the fixed seats are slidably sleeved with the book support arm; a second motor is bolted to the surface of the fixed seat; an adjustment rod is bolted to the output end of the second motor; a transmission ring is provided through the surface of the adjustment rod, and the transmission ring is fixedly sleeved with the surface of the book support arm.

[0011] By adopting the above technical solution, and by setting an adjustment mechanism, the rotation of the second motor drives the adjustment rod to rotate, and the rotation of the adjustment rod causes the transmission ring to move the book support arm, thereby adjusting the position of the book support arm.

[0012] The present invention is further configured such that: a slide is bolted to the bottom of the fixed base, and a slide rail is slidably connected to the inner wall of the slide, and the slide rail is bolted to the surface of the fixed base.

[0013] By adopting the above technical solution, the installation of slide blocks and slide rails prevents the fixed frame from shifting and improves stability.

[0014] The present invention is further configured such that a nut is threaded onto the surface of the adjusting screw.

[0015] By adopting the above technical solution, the adjusting screw is fixed by setting a nut, thereby improving stability.

[0016] The present invention is further configured such that a rotating groove is formed on the surface of the adjusting screw.

[0017] By adopting the above technical solution, the rotating groove is set to facilitate the rotation of the adjusting screw and make adjustment convenient.

[0018] In summary, this utility model has the following beneficial effects:

[0019] This invention uses a coaxial drive transmission system to drive two sets of book feeding modules, one inside and one outside, to perform alternating phase drive. Compared with the traditional single-sided book feeding mechanism, it improves the working efficiency by more than 40% and realizes zero-speed handover control of book transfer, which improves the efficiency of book feeding. Each book support arm is equipped with a second motor, which can handle books with real-time changes in spine height to achieve diversified production. Attached Figure Description
