Description

Technical Field

[0001] This utility model relates to the field of printing and binding equipment, and in particular to a clamping mechanism for perfect binding book covers. Background Technology

[0002] Perfect binding, as an efficient and robust bookbinding method, is widely used in the post-processing of various printed materials such as books, magazines, and albums. The precise fit between the cover and the book block is a crucial factor in determining the quality of perfect-bound books, and the cover clamping mechanism is the core component for achieving this. Its performance directly affects the sealing accuracy, binding efficiency, and final product quality.

[0003] Currently, the cover clamping mechanism of perfect binding equipment on the market adopts an independent drive mode for the left and right clamping plates and the support plate, which requires multiple power sources and transmission devices. This not only increases the manufacturing cost and maintenance difficulty of the equipment, but also easily leads to timing misalignment between the clamping action of the clamping plate, the supporting action of the support plate, and the movement of the book block due to the output deviation of multiple power sources. In actual production, this misalignment will cause the cover to be unstable during the support stage and the force imbalance at the moment of clamping, which will lead to quality problems such as cover wrinkles and poor adhesion between the spine and the cover, thus reducing the production quality. In order to solve the above problems, we propose a perfect binding book cover clamping mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a book cover clamping mechanism for perfect binding, which has the advantage of high synchronization between the clamping plate and the support plate, and can meet the needs of high production.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a book cover clamping mechanism for perfect binding, including a fixed base, a reducer mounted on the surface of the fixed base, a motor mounted on the surface of the reducer, a drive shaft mounted on the output end of the reducer, and the other end of the drive shaft rotatably connected to the inner wall of the fixed base, two first gears and two first bevel gears mounted on the surface of the drive shaft, with the two first gears located inside the two first bevel gears, two bases mounted on the top of the fixed base, a clamping mechanism provided on the top of the bases, and a book-supporting mechanism provided on the inner side of the bases.

[0006] By adopting the above technical solution, the left and right clamping plates are linked through the same power-driven spindle gear transmission system. With the synchronous drive of the left and right clamping plates and the tray, the cover clamping action and the book block movement maintain synchronous linear speed and the synchronization time is minimized. This achieves precise forming of the cover, improves binding quality and efficiency, meets the needs of high-speed production, and maximizes production capacity output.

[0007] The present invention is further configured such that: the clamping mechanism includes two second bevel gears, the two second bevel gears meshing with the surfaces of two first bevel gears respectively; a first rotating shaft is fixedly sleeved at the axis of the second bevel gear, and the first rotating shaft is rotatably sleeved with the inner wall of the fixed base; a second gear is fixedly sleeved on the surface of the first rotating shaft; two third gears mesh with the surface of the second gear; a second rotating shaft is fixedly sleeved at the axis of the third gear, and the second rotating shaft is rotatably sleeved with the inner wall of the base; a first support arm is bolted to the top of the second rotating shaft; and a clamping plate is bolted to the top of the first support arm.

[0008] Using the above technical solution, by setting up a clamping mechanism, the rotation of the second bevel gear drives the first rotating shaft to rotate the second gear, the rotation of the second gear drives the third gear to rotate the second rotating shaft, and the second rotating shaft drives the first support arm to make the clamping plate rotate horizontally to clamp the book block cover.

[0009] The present invention is further configured such that: the book-supporting mechanism includes two fourth gears, the two fourth gears respectively mesh with the surfaces of two first gears, and the fourth gears are rotatably connected to the surface of the base; the surfaces of the fourth gears mesh with two fifth gears; a third rotating shaft is fixedly sleeved at the axis of the fifth gears, and the third rotating shaft is rotatably connected to the surface of the fixed seat; a second support arm is fixedly sleeved on the surface of the third rotating shaft; and a support plate is installed between the tops of the second support arms.

[0010] Using the above technical solution, by setting up a book-supporting mechanism, the rotation of the fourth gear drives the rotation of the fifth gear, the rotation of the fifth gear causes the rotation of the third shaft, and the rotation of the third shaft drives the second support arm to move the support plate up and down to support the book block.

[0011] The present invention is further configured such that: a clamp is provided on the surface of the clamping plate, and a bolt is threadedly connected between the clamp and the inner wall of the clamping plate.

[0012] By adopting the above technical solution, the chuck and bolts are designed to facilitate chuck replacement and reduce maintenance costs.

[0013] The present invention is further configured such that: a fixing block is bolted to the inner wall of the fixing seat, and the fixing block is rotatably sleeved with the surface of the transmission shaft.

[0014] By adopting the above technical solution, the transmission shaft is fixed by setting a fixing block, thereby improving stability.

[0015] The present invention is further configured such that the surface of the fixing base is provided with mounting holes.

[0016] The above technical solution, with its mounting holes, facilitates installation and use.

[0017] In summary, this utility model has the following beneficial effects:
