Description

Technical Field

[0001] This utility model relates to the field of printing post-processing equipment technology, and in particular to a cutter holder with an angle fine-tuning mechanism. Background Technology

[0002] In the book printing and binding industry, cutting is an essential process. Whether it's a single sheet of paper or a book before binding, it needs to be precisely cut using a cutter to ensure neat edges and dimensions that meet specifications.

[0003] Most existing cutter stands adopt a vertical cutting design. These devices typically include a fixed frame and a pressure plate for pressing the paper. Driven by a drive mechanism (such as a hydraulic cylinder or motor), the cutter moves up and down along a fixed vertical guide rail to cut the pressed paper.

[0004] However, in the aforementioned cutter holder, the movement trajectory of the cutter is fixed, typically allowing only parallel (90-degree) cuts to the base plate. While this design can meet the requirements for conventional book cutting, it lacks flexibility.

[0005] In actual production, especially when dealing with designs of different formats, production of irregularly shaped books, or certain special binding processes, it is often necessary to cut paper at a specific angle. Existing fixed cutter holders cannot achieve this function, thus limiting their application range and failing to meet diverse printing and cutting needs.

[0006] Therefore, this utility model proposes a cutter holder with an angle fine-tuning mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of fixed cutting angle and single function of existing cutter holders, which cannot meet the needs of different book sizes or irregular shapes, this utility model aims to provide a cutter holder with an angle fine-tuning mechanism that has been improved in structure and can effectively solve the above problems.

[0008] This utility model provides a cutter holder with an angle fine-tuning mechanism, including: a base plate, a mounting plate, and a cutter; the cutter holder also includes an adjustment component and a drive component.

[0009] One side of the mounting plate is rotatably connected to the base plate, and the other side of the mounting plate is slidably connected to an arc-shaped groove in the base plate. The adjustment assembly includes a threaded seat rotatably connected to the base plate, an adjusting screw threadedly engaged with the threaded seat, and a handwheel fixed to one end of the adjusting screw; the other end of the adjusting screw is rotatably connected to the other side of the mounting plate. This structure is used to change the tilt angle of the mounting plate by rotating the handwheel, which pushes the mounting plate to swing around its rotation connection point via the adjusting screw.

[0010] The drive assembly includes a fixing plate fixed to the top of the mounting plate and a second hydraulic rod fixed to the top of the fixing plate. The telescopic end of the second hydraulic rod is connected to the cutter and is used to drive the cutter to perform a cutting action. A sliding groove is provided on the mounting plate, and the cutter slides within the sliding groove. This structure ensures that the cutter always follows the adjusted angle of the mounting plate to perform a smooth linear cutting motion.

[0011] Preferably, the drive assembly further includes a second guide rod, and the cutter is fixedly connected to one end of the second guide rod. The second guide rod provides additional rigid constraint to the cutter when performing the cutting action, and together with the slide groove, ensures that the cutter will not deviate or vibrate under force, thereby improving cutting accuracy.

[0012] Preferably, the cutter holder with angle fine-tuning mechanism further includes a support plate and a pressing assembly. The support plate is fixedly disposed on the base plate to provide a positioning reference for the workpiece. The pressing assembly is mounted on the support plate and is used to independently press and fix the workpiece before cutting.

[0013] Furthermore, the pressing assembly includes a first hydraulic rod fixed to the top of the support plate and a pressure plate fixedly connected to the telescopic end of the first hydraulic rod. The first hydraulic rod provides the pressure plate with a smooth downward pressing force and a lifting force.

[0014] Preferably, the pressing assembly further includes a first guide rod, and the pressure plate is fixedly connected to the first guide rod. The first guide rod ensures that the pressure plate can smoothly and vertically rise and fall under the drive of the first hydraulic rod, preventing uneven pressing force or jamming.

[0015] In one specific implementation, the first guide rod is slidably connected to the support plate and arranged parallel to the first hydraulic rod. This parallel arrangement ensures optimal guiding effect and the most stable structure.

[0016] Preferably, a flexible rubber pad is fixed to the bottom of the pressure plate. This flexible rubber pad provides sufficient friction while buffering the clamping force, preventing indentations or damage to the surface of the workpiece (such as paper books).

[0017] Preferably, the cutter holder with angle fine-tuning mechanism further includes a base, and the base plate is fixed to the base. The base is used to raise the entire operating platform and provide stable ground support.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting an adjustment component, drives the mounting plate that carries the cutter and the drive component to swing. One side of the mounting plate is rotatably connected to the base plate, and the other side slides along the arc groove of the base plate. This solves the problem that the existing cutter holder has a fixed cutting angle and cannot meet diverse cutting needs. It achieves the technical effect of being able to precisely adjust the cutting angle of the cutter and improve the adaptability of equipment specifications.

[0019] 2. This utility model solves the problem of easy shaking or skewing of the cutter when it is under the force of cutting in an inclined state by opening a sliding groove on the mounting plate and setting a second guide rod. This achieves the technical effect of ensuring accurate cutting trajectory and smooth operation of the cutter, and ensuring neat and burr-free edges after cutting.

[0020] 3. This utility model solves the problems of low adjustment accuracy of the angle adjustment mechanism or the angle deviation caused by vibration after adjustment by using a threaded engagement of handwheel, adjusting screw and threaded seat in the adjustment component. It achieves the technical effect of labor-saving adjustment operation, precise fine adjustment, and ensuring stable and reliable cutting angle by utilizing the self-locking property of the screw.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 5 This utility model provides a cutter holder with an angle fine-tuning mechanism, which aims to solve the problem that the cutting angle of the cutter holder in the prior art is fixed and cannot be adjusted, resulting in the inability to adapt to different book sizes or irregular cutting needs.

[0025] like Figure 1 and Figure 2 As shown, the cutter holder with an angle fine-tuning mechanism includes a base 9 and a base plate 1 fixedly connected to the base 9. The base 9 supports the entire cutter holder and improves the stability of the equipment placement. The base plate 1 serves as a mounting platform, supporting the other components of the cutter holder. A support plate 2 is fixedly mounted on the base plate 1 and is used to mount the pressing assembly 3. One side of the mounting plate 4 is rotatably connected to the base plate 1, and the other side of the mounting plate 4 is slidably connected to the arc-shaped groove 704 opened on the base plate 1. The mounting plate 4 is used to support the cutter 6 and the drive assembly 8. The cutter 6 is mounted on the mounting plate 4. The drive assembly 8 is mounted on the mounting plate 4 and is used to drive the cutter 6 to perform the cutting action. An adjustment assembly 7 is connected between the base plate 1 and the mounting plate 4 and is used to drive the mounting plate 4 to swing around the side of the base plate 1 that is rotatably connected to it. The pressing assembly 3 is mounted on the support plate 2 and is used to press the workpiece before cutting.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the mechanism of this embodiment lies in the adjustable-angle cutting assembly, which includes a mounting plate 4, an adjustment component 7, and a drive component 8. The adjustment component 7 includes a threaded seat 703, an adjusting screw 702, and a handwheel 701. The threaded seat 703 is rotatably connected to the base plate 1. The adjusting screw 702 is threadedly engaged with the threaded seat 703, and one end of the adjusting screw 702 is rotatably connected to the other side of the mounting plate 4. The handwheel 701 is fixed to the other end of the adjusting screw 702. This structure allows the handwheel 701 to rotate when it is turned, causing the adjusting screw 702 to rotate. The adjusting screw 702 screws in or out of the threaded seat 703, thereby pushing the mounting plate. The other side of the mounting plate 4 is rotatably connected to one side of the base plate 1 and swings around it, while the other side of the mounting plate 4 slides along the arc groove 704, realizing precise fine-tuning of the angle of the mounting plate 4; the drive assembly 8 includes a fixing plate 5 fixed to the top of the mounting plate 4 and a second hydraulic rod 801 fixed to the top of the fixing plate 5; the telescopic end of the second hydraulic rod 801 is connected to the cutter 6 to provide cutting power; a sliding groove 803 is provided on the mounting plate 4, and the cutter 6 slides in the sliding groove 803. This structure ensures that the cutter 6 always follows the angle adjusted by the mounting plate 4 in a linear motion when cutting down and lifting up; in order to further improve the stability of the movement of the cutter 6, such as Figure 3 As shown, the drive assembly 8 also includes a second guide rod 802. The cutter 6 is fixedly connected to one end of the second guide rod 802. The second guide rod 802 and the slide 803 together constrain the movement trajectory of the cutter 6 to ensure the smoothness and accuracy of the cutting. To ensure stable fixation of the paper book for adjustments to the cutting angle and the cutting process, please refer to the following instructions. Figure 1 , Figure 2 and Figure 5 The cutter holder with the angle fine-tuning mechanism also includes a pressing assembly 3 mounted on the support plate 2; The pressing assembly 3 includes a first hydraulic rod 301 and a pressure plate 303; The first hydraulic rod 301 is fixed to the top of the support plate 2. The telescopic end of the first hydraulic rod 301 is fixedly connected to the pressure plate 303. The first hydraulic rod 301 is used to drive the pressure plate 303 to press down or lift up, thereby realizing the fixing and loosening of the workpiece. To ensure the stability of the pressure plate 303 during its up-and-down movement and to prevent skewing during pressing, the pressing assembly 3 also includes a first guide rod 302. The first guide rod 302 is slidably connected to the support plate 2 and is set parallel to the first hydraulic rod 301; the pressure plate 303 is slidably connected to the first guide rod 302. Driven by the first hydraulic rod 301, the pressure plate 303 will slide along the length of the first guide rod 302. The first guide rod 302 provides guidance for the pressure plate 303 to ensure a smooth pressing process. To further protect the paper products, a flexible rubber pad is fixed to the bottom of the pressure plate 303. The flexible rubber pad provides sufficient friction to prevent the workpiece from sliding while avoiding pressure damage to the surface of the paper products caused by the pressure plate 303.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to improve the cutting stability of the cutter 6, please refer to... Figure 3 The drive assembly 8 also includes a second guide rod 802, and the cutter 6 is fixedly connected to one end of the second guide rod 802. The second guide rod 802 and the slide groove 803 on the mounting plate 4 together constrain the movement trajectory of the cutter 6 to ensure the smoothness and accuracy of the cutting. As a preferred embodiment, to ensure the best guiding effect of the first guide rod 302, please refer to... Figure 5 The first guide rod 302 is slidably connected to the support plate 2 and is set parallel to the first hydraulic rod 301; As a preferred embodiment, to improve the placement stability and load-bearing capacity of the entire device, please refer to... Figure 1 The cutter holder also includes a base 9, and the base plate 1 is fixed on the base 9.

[0028] The working principle of the cutter holder with angle fine-tuning mechanism of this utility model is as follows: First, place the workpiece on the base plate 1 and make its edge close to the support plate 2 to achieve initial positioning. Then, start the pressing assembly 3. The first hydraulic rod 301 fixed to the top of the support plate 2 extends and drives the pressure plate 303 fixedly connected to its telescopic end to move downward. During the movement, the pressure plate 303 is simultaneously guided by the sliding of the first guide rod 302 to ensure that it presses down smoothly. The flexible rubber pad at the bottom of the pressure plate 303 firmly presses the workpiece onto the base plate 1 to prevent the workpiece from shifting during subsequent adjustment and cutting.

[0029] When the cutting angle needs to be adjusted, the handwheel 701 of the adjusting assembly 7 is rotated. The handwheel 701 drives the adjusting screw 702 to rotate. The adjusting screw 702 is threadedly engaged with the threaded seat 703 rotatably connected to the base plate 1, thereby generating axial displacement. The end of the adjusting screw 702 rotatably connected to the other side of the mounting plate 4 pushes the mounting plate 4. The mounting plate 4 pivots about the side rotatably connected to the base plate 1. At the same time, the other side of the mounting plate 4 slides along the arc groove 704 on the base plate 1. This structure allows the tilt angle of the mounting plate 4 and the entire drive assembly 8 and the cutter 6 fixed on it to be precisely changed.

[0030] After the angle adjustment is completed, the drive assembly 8 is activated, and the second hydraulic rod 801, which is fixed to the top of the fixed plate 5, extends. Its telescopic end drives the cutter 6 to move downward. When the cutter 6 moves, one side of it slides into the groove 803 opened in the mounting plate 4. At the same time, the cutter 6 is fixedly connected to one end of the second guide rod 802. Under the dual constraints of the groove 803 and the second guide rod 802, the cutter 6 descends smoothly according to the adjusted angle to cut the pressed workpiece. After the cutting is completed, the second hydraulic rod 801 retracts and drives the cutter 6 to reset. The first hydraulic rod 301 retracts and drives the pressure plate 303 to lift, so that the workpiece can be removed. Throughout the process, the base 9 provides stable support for the base plate 1.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
