[0002] The book front edge trimming mechanism is an indispensable device in the process of book edge trimming after printing. Since the book front edge trimming is a key process for book edge trimming, it is directly related to the quality of the finished book. Therefore, there are very high requirements for the stability and cutting efficiency of the trimming mechanism.

[0003] The prior art uses a book delivery push rod in an intermittent stepping operation mode to deliver books and periodicals to a front edge trimming station, and when the books and periodicals stop running, a trimming mechanism trims the cover of the books and periodicals.

[0004] There are several disadvantages to this approach. One is that the intermittent stepping book feeding method requires frequent switching between the running and stopping states, which cannot effectively improve the efficiency of trimming the front edge of books and periodicals. Secondly, due to the start-stop inertia during the book and periodical transmission process, the trimming accuracy of books and periodicals decreases, increasing the scrap rate and reducing the quality of the finished books and periodicals.

[0027] The book front edge trimming mechanism is an indispensable device in the process of book edge trimming after printing. Since the book front edge trimming is a key process for book edge trimming, it is directly related to the quality of the finished book. Therefore, there are very high requirements for the stability and cutting efficiency of the trimming mechanism.

[0028] In the related art, the prior art is to use a book delivery push rod and an intermittent stepping operation mode to transport books and periodicals to a front edge trimming station, and when the books and periodicals stop running, a trimming mechanism is used to trim the cover of the books and periodicals.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a reverse trimming mechanism for the front edge of books and periodicals. When it is needed, it is only necessary to start the servo motor 12 to drive the eccentric disk 13 to rotate, thereby driving the movable plate 15 equipped with the eccentric cutter 18 to move forward and backward, and complete the forward and backward movements of the eccentric cutter 18, thereby realizing the trimming operation of the books and periodicals 19. The device drives the movable plate 15 to move forward and backward through the structure of the crank connecting rod, thereby driving the eccentric cutter to cut the books and periodicals 19, ensuring the trimming quality of the front edge of the books and periodicals 19, improving the trimming efficiency of the books and periodicals, and increasing the quality of the product.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 2 The embodiment of the present application provides a book front edge reverse trimming mechanism, including a cutting assembly 1; the cutting assembly 1 includes: a servo motor 12 is arranged at the bottom of a mounting plate 11; an eccentric disk 13 is arranged at the top of the mounting plate 11 and connected to the servo motor 12; an adjusting swing arm 131 is arranged at the top of the eccentric disk 13; a mounting frame 14 is arranged at the top of the mounting plate 11; a transfer swing arm 141 is rotatably arranged at the bottom of the mounting frame 14 and is rotatably connected to the adjusting swing arm 131; a movable plate 15 is arranged at the top of the mounting plate 11 and is rotatably connected to the transfer swing arm 141; a slider 16 is symmetrically arranged at the bottom of the movable plate 15; a slide seat 161 is symmetrically arranged at the top of the mounting plate 11 and is slidably connected to the slider 16; a mounting seat 17 is arranged on the movable plate 15; an eccentric cutter 18 is arranged on the mounting seat 17; and books 19 are arranged on the outside of the eccentric cutter 18.

[0032] The book 19 is conveyed to one side of the eccentric cutter 18 by the bottom book feeding belt, and the book 19 is clamped by the internal clamping mechanism. The working principle of the device refers to the paragraph

[0051] recorded in the specification of the utility model publication number "CN216099098U", which belongs to common knowledge and is not repeated here. The servo motor 12 is started by an external power supply to drive the eccentric disk 13 to rotate, thereby driving the crank connecting rod composed of the adjusting swing arm 131 and the switching swing arm 141 to work. Since the slider 16 arranged at the bottom of the movable plate 15 is slidably connected with the slide seat 161, the crank connecting rod drives the movable plate 15 to move forward and backward, and completes the forward and backward movement of the eccentric cutter 18, thereby realizing the cutting operation of the book 19. The device drives the movable plate 15 to work forward and backward through the structure of the crank connecting rod, thereby driving the eccentric cutter to cut the book 19, ensuring the cutting quality of the front edge of the book 19, improving the cutting efficiency of the book, and increasing the quality of the product.

[0033] In some embodiments, an auxiliary component 2 is disposed on the top of the mounting plate 11 , and the auxiliary component 2 includes a protective shell 21 disposed on the top of the mounting plate 11 .

[0034] A protective shell 21 is disposed on the top of the mounting plate 11 , which can shield and protect the eccentric disk 13 and increase the service life of the eccentric disk 13 .

[0035] In some embodiments, the mounting seat 17 is connected to the movable plate 15 by bolts.

[0036] The mounting seat 17 and the movable plate 15 are connected by bolts, so that it is convenient to disassemble the mounting seat 17 later so as to replace the eccentric cutter 18 and avoid affecting the cutting of the books and periodicals 19.

[0037] In some embodiments, the auxiliary component 2 further includes a docking groove 22 opened on the mounting seat 17 .

[0038] A docking groove 22 is provided on one side of the mounting seat 17 , so that when the mounting seat 17 is subsequently installed, the docking groove 22 provided on one side of the mounting seat 17 can be docked with the movable plate 15 , which makes it convenient to use bolts for fixed installation.

[0039] In some embodiments, the auxiliary component 2 further includes a stopper 23 symmetrically arranged on the mounting seat 17 .

[0040] Stoppers 23 are symmetrically arranged on both sides of the mounting seat 17 , so that when the docking groove 22 docks with the movable plate 15 , the movable plate 15 is restricted inside the two stoppers 23 , making it convenient for operators to use bolts for fixing and installation, thereby increasing operating efficiency.

[0041] In some embodiments, the auxiliary component 2 further includes: a plate body 24 disposed on the top of the mounting plate 11 and slidably connected to the movable plate 15 .

[0042] A plate body 24 is arranged on the top of the mounting plate 11 and is slidably connected to the movable plate 15 , which can increase the structural strength of the movable plate 15 and make the movable plate 15 move more smoothly, thereby increasing the stability of the device.

[0043] In some embodiments, the plate body 24 is connected to the mounting plate 11 by bolts.

[0044] The plate body 24 and the mounting plate 11 are connected by bolts, so that it is convenient to disassemble the plate body 24 later so as to maintain or disassemble the movable plate 15.

[0045] In some embodiments, the mounting bracket 14 is connected to the mounting plate 11 by bolts.

[0046] The mounting frame 14 and the mounting plate 11 are arranged to be connected by bolts, so that it is convenient to disassemble the mounting frame 14 later, thereby facilitating the disassembly of the transfer swing arm 141, so as to maintain or replace the parts.
