Description

Technical Field

[0001] This utility model relates to the field of book binding equipment technology, and in particular to a vertical lifting device for a binding machine trolley clamping mechanism. Background Technology

[0002] A perfect binding machine is a device that clamps the book block and sequentially performs spine milling, glue application, and cover covering to complete the perfect binding of a book. In existing technology, the clamping mechanism of the carriage usually uses symmetrical clamping plates that synchronously close towards the center to clamp the book. However, this type of clamping mechanism has significant drawbacks: First, due to insufficient synchronization accuracy of the drive components or uneven distribution of clamping force, the clamping plates are prone to asynchronous movement, resulting in insecure book clamping or tilting and deformation under force, which in turn affects the uniformity of spine milling and glue application, ultimately reducing the quality of the finished perfect bound book; Second, the lifting mechanism of the clamping station often relies on four cams to control the lifting of the clamping platform, but because cam machining and assembly errors are difficult to eliminate, the lifting stroke of the four cams is prone to deviation, causing the clamping platform to be partially suspended, resulting in uneven force during book cover covering, leading to inconsistent square and round corners on the front and back sides of the perfect bound book, seriously affecting the uniformity of appearance and glue layer thickness.

[0003] Furthermore, existing clamping mechanisms lack precise control over clamping thickness and lifting height. The clamping plate is susceptible to deformation under radial loads during lifting, further exacerbating clamping misalignment. These technical deficiencies not only hinder the improvement of perfect binding efficiency but also increase the rate of defective books. Therefore, a new clamping mechanism capable of high-precision synchronous clamping, uniform force application, and stable lifting is urgently needed to solve these problems. Summary of the Invention

[0026] Example, refer to Figure 1-6 A vertical lifting device for a clamping mechanism of a binding machine trolley includes a first clamping plate 1 and a second clamping plate 2, and further includes...

[0027] The driving assembly 3 is used to drive the second clamping plate 2 to move closer to or further away from the first clamping plate 1. The driving assembly 3 includes four support rods 301 mounted on the first clamping plate 1 and slidably connected to the second clamping plate 2, a fixed plate 302 connected to the ends of the support rods 301, and a clamping power unit 305 for driving the first push-pull part 303 and the second push-pull part 304 to move the second clamping plate 2. The clamping power unit 305 drives the first and second push-pull parts 303 / 304 to drive the second clamping plate 2 to slide along the support rods 301, thereby clamping or releasing the book.

[0028] The lifting assembly 4 is used to drive the first clamping plate 1 to rise and fall. The lifting assembly 4 includes a base 401, a guide rod seat 402 connecting the base 401 and the first clamping plate 1, a linkage block 403 fixed on the first clamping plate 1 and slidingly engaged with the base 401, a lifting screw 404 screwed to the linkage block 403, a first bevel gear 405 provided at one end of the lifting screw 404, a second bevel gear 406 meshing with the first bevel gear 405, and a lifting motor 407 for driving the second bevel gear 406 to rotate. The lifting motor 407 drives the second bevel gear 406 to rotate, thereby causing the lifting screw 404 to rotate, so that the linkage block 403 moves along the lifting screw 404, thereby realizing the lifting and falling of the first clamping plate 1.

[0029] This invention uses a clamping power unit 305 to drive the first and second push-pull units 303 / 304, causing the second clamping plate 2 to slide along the support rod 301, so that the second clamping plate 2 moves closer to or away from the first clamping plate 1, thereby clamping the book, ensuring the consistency of synchronous clamping and the uniformity of clamping force, thus improving the binding effect; the lifting motor 407 drives the second bevel gear 406 to rotate, which drives the lifting screw 404 to rotate, so that the linkage block 403 moves along the lifting screw 404, realizing the lifting and lowering of the first clamping plate 1 and the second clamping plate 2, thereby controlling the thickness of the book's adhesive layer.

[0030] In an optional embodiment of this utility model, the first push-pull part 303 includes an anti-collision plate 3031 provided on the second clamping plate 2, a first lead screw 3032 screwed to the second clamping plate 2 and the anti-collision plate 3031, a limiting sleeve 3033 provided on the fixed plate 302 corresponding to the anti-collision plate 3031, and a first extension rod 3034 provided at the end of the first lead screw 3032 and rotatably connected to the limiting sleeve 3033. Preferably, a bearing can be provided on the fixed plate 302 in this embodiment, and the first extension rod 3034 is fixedly connected to the inner ring of the bearing. After the first lead screw 3032 rotates, it drives the second clamping plate 2 to move. The setting of the limiting sleeve 3033 can limit the second clamping plate 2, preventing the second clamping plate 2 from moving too far away from the first clamping plate 1. The anti-collision plate 3031 reduces the impact on the second clamping plate 2. The limiting sleeve 3033 and the bearing ensure that the first extension rod 3034 rotates smoothly, improving the clamping accuracy and the durability of the mechanism.

[0031] In an optional embodiment of this utility model, the second push-pull part 304 includes a sleeve 3041 disposed on the second clamping plate 2, a second lead screw 3042 screwed to the sleeve 3041, a positioning ring 3043 disposed on the fixed plate 302, and a second extension rod 3044 disposed at one end of the second lead screw 3042 and rotatably connected to the positioning ring 3043. Preferably, a bearing may be disposed on the fixed plate 302 in this embodiment, and the second extension rod 3044 is fixedly connected to the inner ring of the bearing. The second lead screw 3042 is screwed to the sleeve 3041, and the second extension rod 3044 is synchronously driven to rotate by the chain, thereby pushing the second clamping plate 2 to move. The coordinated work of the first and second push-pull parts 303 / 304 enhances the uniformity of the clamping force, and the placement of the positioning ring 3043 and the bearing reduces lead screw deviation and avoids jamming.

[0032] In an optional embodiment of this utility model, the clamping power unit 305 includes a first sprocket 3051 disposed at the end of the first extension rod 3034, a second sprocket 3052 disposed at the end of the second extension rod 3044, a chain 3053 connecting the first sprocket 3051 and the second sprocket 3052, a drive rod 3054 disposed at the other end of the first lead screw 3032 and rotatably connected to the first clamping plate 1, a driven gear 3055 connected to the drive rod 3054, and a driving gear 3056 meshing with the driven gear 3055 for driving the driving gear. The clamping motor 3057 rotates. Preferably, in this embodiment, a bearing can be provided on the first clamping plate 1, and the drive rod 3054 is fixedly connected to the inner ring of the bearing. The clamping motor 3057 is fixedly connected to the first clamping plate 1. The clamping motor 3057 drives the drive gear 3056 to drive the driven gear 3055, so that the drive rod 3054 rotates. The screw movement of the first and second push-pull parts 303 / 304 is synchronously controlled by the sprocket and chain. The chain drive realizes the synchronous action of the first and second push-pull parts 303 / 304, ensuring clamping symmetry.

[0033] In an optional embodiment of this utility model, a weight-reducing groove 201 is provided on the second clamping plate 2, and the sleeve 3041 is fixed at the bottom of the weight-reducing groove 201. The weight-reducing groove reduces the weight of the second clamping plate 2, reduces the overall weight, and increases the lifting speed.

[0034] In an optional embodiment of this utility model, a guide rod 306 is provided in the weight-reducing groove 201. The guide rod 306 and the fixing plate 302 are slidably engaged. The guide rod 306 can limit the movement trajectory of the second clamping plate 2, prevent deviation, enhance the stability during the clamping process, and avoid damage to the book due to clamping tilt.

[0035] In an optional embodiment of this utility model, the lifting assembly 4 further includes two lifting guide rods 408 that slide in cooperation with the linkage block 403. The two ends of the lifting guide rods 408 are fixedly connected to the guide rod seats 402 respectively. The lifting guide rods 408 cooperate with the linkage block 403 to constrain the force direction of the lifting screw 404, reduce the radial load of the lifting screw 404, prevent bending deformation, and extend the service life of the lifting screw 404.

[0036] In an optional embodiment of this utility model, the lifting assembly 4 further includes a hanging plate 409 vertically connected to the base 401. An adjusting plate 411 is fixedly connected to the hanging plate 409 by a first bolt 410. The adjusting plate 411 is provided with a mounting plate 412 for supporting the lifting motor 407. Preferably, the adjusting plate 411 in this embodiment can be provided with a waist hole. The adjusting plate 411 can adjust the height of the mounting plate 412 to adapt to lifting motors of different sizes, which facilitates maintenance and motor replacement and enhances the adaptability of the mechanism.

[0037] In an optional embodiment of this utility model, the drive assembly 3 further includes a transverse plate 307 arranged along the length direction of the fixed plate 302, a second bolt 308 fixing the transverse plate 307 to the fixed plate 302, a longitudinal plate 309 connecting the transverse plate 307 and the first clamping plate 1, and a thickness scale 310 provided on the longitudinal plate 309. The transverse plate 307 is fixed by the second bolt 308, the longitudinal plate 309 is connected to the first clamping plate 1, and the thickness scale 310 displays the clamping thickness and provides an intuitive reference for the clamping thickness. The arrangement of the transverse plate 307 and the longitudinal plate 309 can enhance the structural rigidity and prevent the assembly from deforming.
