Description

Technical Field

[0001] This invention relates to the field of exercise book production equipment technology, and more specifically to a high-precision cutting device for exercise book production. Background Technology

[0002] In the production of printed materials such as exercise books and books, the cutting process is a key step to ensure that the finished products are uniform in size and neat in appearance. Existing technologies include some notebook and book cutting machines; for example, "Application No.: CN202122135631.2", which uses an electric push rod to drive a pusher plate to push the notebook and uses a hydraulic cylinder to drive a cutter for cutting. However, in this solution, the pusher plate only has a unidirectional pushing function and lacks an effective lateral positioning and stacking mechanism for the books. It is difficult to ensure the neatness of stacked books before pushing, and cutting deviations are easily caused by paper misalignment. At the same time, its cutting platform width is fixed, and it cannot flexibly adjust the support area according to different sizes of notebooks, resulting in poor adaptability. Existing cutting machines also include three-way cutting of exercise books and books, which can speed up the process and achieve high precision, such as "Application No.: CN202120172154.4". It uses multiple cylinders and motor-driven book clamping plates and sliding plates to tap and stack books. Although this solution achieves multi-directional positioning, its support plate and overall structure are still fixed, lacking stable support for the suspended part of the paper during the cutting process. When cutting exercise books and books of different sizes, rough edges or tears are easily produced during the cutting process. At this time, although different specifications of equipment can be used or a large number of equipment parts can be replaced, the cost is high and the operation is inconvenient. Therefore, there is an urgent need to propose a high-precision cutting device that can achieve rapid positioning, accurate and easy adjustment, and stably support various sizes of workbooks. Summary of the Invention

[0003] The purpose of this invention is to provide a high-precision cutting device for notebook production in order to solve the above-mentioned technical problems.

The longitudinal adjustment assembly is used to longitudinally displace the multiple sets of pads on the same horizontal plane to expand or contract and adjust the top fabric surface of the multiple sets of pads. The output end of the first telescopic device is fixed to the longitudinal adjustment assembly for left and right adjustment. The lateral adjustment mechanism has an adjustable longitudinal stop and is close to and located at the top of the pads. The limiting assembly has an adjustable lateral stop.

The bottom end of each set of side moving plates is fixed to the first slider of one set, and each set of first sliders is threaded through by the first threaded rod of one set. The top end of the first housing is fixed to the central fixed plate. The first slider part moves out of the first housing. The first threaded rod is rotatably connected to the first housing. The output end of the first forward and reverse motor passes through the first housing and is fixed to the first threaded rod. When there are two or more sets of the first threaded rod, the lead of the first threaded rod further away from the center rod is larger; a fifth rangefinder is installed inside the frame to detect the movement position of the side moving plate during the expansion and contraction process.

[0009] As a preferred embodiment of the present invention, the clamping device includes a second housing, a second guide bar fixedly installed inside the second housing, a second threaded rod rotatably connected inside the second housing, a second forward and reverse motor fixedly installed outside the second housing, and a second slider slidably connected to the second guide bar. The outer side of the second housing is fixed to the output end of the inclined push mechanism. The threads on the second threaded rod are symmetrical in front and back at the center. Two sets of second sliders are symmetrically arranged in front and back at the center end of the second threaded rod. The second slider passes through the thread of the second threaded rod. The second slider part is exposed outside the second housing and moves, and it is fixed to the transverse cutter. A third rangefinder is fixed inside the frame to detect the displacement of the transverse cutter adjustment.

[0010] As a preferred embodiment of the present invention, the longitudinal side cutting mechanism includes a fifth telescopic device and a longitudinal cutter fixed at its output end; The push-adjustment assembly includes a sixth expansion joint fixed to the outside of the frame and an opening on the frame. The output end of the sixth expansion joint is fixed to the fifth expansion joint, and part of the fifth expansion joint moves within the opening. A fourth distance measuring device is fixed to the outside of the sixth expansion joint to detect the displacement of the fifth expansion joint adjusted by the operation of the sixth expansion joint. The output end of the sixth expansion joint faces to the left.

Detailed Implementation

[0017] like Figures 1-5 As shown, the present invention proposes a high-precision cutting device for workbook production, comprising a frame 1 and a book-supporting mechanism 2, a book-pressing mechanism 3, a longitudinal side-cutting mechanism 4, and a transverse side-cutting mechanism 5 disposed on the frame 1; the device can realize the pressing of stacked workbooks in one step and then the subsequent cutting, significantly improving the cutting accuracy and production efficiency.

[0018] The tray support mechanism 2 includes a tray assembly a, a longitudinal adjustment assembly b disposed at the bottom of the tray assembly a, a first telescopic device c and a limiting assembly g fixed on the frame 1, and a transverse adjustment mechanism e disposed at the top of the tray assembly a. The tray assembly a consists of multiple sets of pads arranged longitudinally (front and back) with their tops on the same horizontal plane, used to support stacked workbooks; The longitudinal adjustment component b is used to drive multiple sets of pads to move longitudinally on the same horizontal plane, thereby expanding or shrinking the support fabric at the top of the pads to accommodate workbooks of different sizes. The output end of the first telescopic device c is fixedly connected to the longitudinal adjustment component b, which can drive the entire pallet assembly a to move left and right to achieve alignment adjustment with the cutter; and can be used to pick up and put down stacked workbooks at fixed points, with high safety. The horizontal adjustment mechanism e has an adjustable longitudinal stop (i.e., the stop extends in the left and right direction), located at the top of the pad and close to the pad, to limit the left and right position of the workbook; the limiting component g has an adjustable transverse stop (i.e., the stop extends in the front and back direction), to limit the front and back position of the workbook; through the above multi-directional adjustable structure, the workbook support mechanism 2 can quickly adapt to the stable support requirements of various sizes of workbooks.

[0019] Furthermore, more specifically: The tray assembly a includes a central fixed plate a1 and several sets of side movable plates a2. The sets of side movable plates a2 are symmetrically distributed on the front and rear sides of the central fixed plate a1, and the tops of the central fixed plate a1 and all the side movable plates a2 are kept on the same horizontal plane. In use, the central fixed plate a1 serves as a reference support, and the side movable plates a2 on the front and rear sides can move towards or away from the central fixed plate a1 synchronously, thereby changing the total support length of the tray, so that the suspended part of the exercise book is effectively supported, and avoids rough edges or tears caused by the paper being suspended during cutting.

[0020] The longitudinal adjustment component b includes a first housing b1, a first guide bar b2 fixedly installed in the first housing b1, a middle rod b3, several sets of first threaded rods b4 symmetrically distributed at both ends of the middle rod b3, a first forward and reverse motor b5 fixedly installed on the outside of the first housing b1, and a first slider b6 slidably connected to the first guide bar b2. The rotation axes of the central rod b3 and the first threaded rod b4 are collinear. The first slider b6, the first threaded rod b4, and the side moving plate a2 are in one-to-one correspondence and have the same number of groups. The bottom end of each group of side moving plates a2 is fixed to a group of first sliders b6. Each group of first sliders b6 is threaded through by a group of first threaded rods b4, so that they can be threaded together. The top end of the first housing b1 is fixed to the central fixed plate a1. The first slider b6 extends out of the first housing b1 to connect with the side moving plate a2. The first threaded rod b4 is rotatably connected to the first housing b1. The output end of the first forward and reverse motor b5 passes through the first housing b1 and is fixed to the first threaded rod b4.

[0021] When the first forward and reverse motor b5 starts, it drives the first threaded rod b4 to rotate. Since the first slider b6 is restricted from rotating by the first guide bar b2, the first slider b6 can only move along the axial direction of the first threaded rod b4, thereby driving the side moving plate a2 to move synchronously. When there are two or more sets of the first threaded rod b4, the lead of the first threaded rod b4 further away from the central rod b3 is larger, which makes the side moving plate a2 further away from the central fixed plate a1 move faster. This can realize that all side moving plates a2 move the same distance in the same time, ensuring the symmetrical expansion and contraction of the pallet assembly a.

[0022] In addition, a fifth rangefinder is installed inside the frame 1. This fifth rangefinder is electrically connected to the PLC controller and is used to detect the movement position of the side moving plate a2 during the expansion and contraction process. It feeds the position signal back to the controller and forms a closed-loop control with the first forward and reverse motor b5 to ensure the displacement accuracy and symmetry of each side moving plate a2.

[0023] Before cutting, the operator or control system drives the side plate a2 to move according to the actual length of the workbook through the first forward and reverse motor b5, so that the total length of the support plate assembly a is suitable for the length of the workbook being used, ensuring that the workbook is stably supported as a whole without any suspended parts. This structure solves the problem in the prior art that the fixed support plate causes the edges of the workbook to be suspended, and cutting is prone to producing rough edges or tears.

[0024] The horizontal adjustment mechanism e includes a third telescopic device e2 fixed to the top of the middle plate a1 and a first baffle e1 fixed to its output end. The bottom end of the first baffle e1 is close to the top end of the middle plate a1. The output end of the third telescopic device e2 is set to the left. A first rangefinder is fixed to the outside of the third telescopic device e2 for detecting the adjustment displacement of the first baffle e1. In use, depending on the width of the exercise book, the third telescopic device e2 drives the first baffle e1 to move to the left or right to the set position. The first rangefinder feeds back the displacement signal to achieve precise lateral positioning. The longitudinal baffle of the first baffle e1 can abut against the unbound side of the exercise book to ensure consistent cutting width.

[0025] The limiting component g includes a fourth telescopic member g1 fixedly mounted inside the frame 1 and a second baffle g2 fixed at its output end. The second baffle g2 is positioned close to the side moving plate a2, and the output end of the fourth telescopic member g1 faces forward. A second rangefinder is fixedly mounted on the outside of the fourth telescopic member g1 for detecting the forward and backward displacement of the second baffle g2. In use, depending on the length of the workbook, the fourth telescopic device g1 drives the second baffle g2 to move forward or backward, cooperating with the horizontal adjustment mechanism e to limit the front and rear positions of the workbook; through the combined action of the horizontal adjustment mechanism e and the limiting component g, the workbooks can be stacked quickly and accurately without the need for repeated manual tapping and adjustment, which greatly improves production efficiency.

[0026] The pressing mechanism 3 includes a second telescopic device 31 fixedly mounted on the frame 1 and a pressing plate 32 detachably fixed to the output end of the second telescopic device 31; the second telescopic device 31 is a cylinder or a hydraulic cylinder, and its output end is set vertically downward; in use, after the workbooks are stacked and positioned on the pallet assembly a, the second telescopic device 31 drives the pressing plate 32 to move downward and press the top of the stacked workbooks. The pressure plate 32 and the output end of the second telescopic device 31 can be detachably fixed, which makes it easy to replace the pressure plate 32 of different sizes or shapes according to different specifications of exercise books. This pressing mechanism 3 can keep the paper stacked tightly during the cutting process and prevent cutting deviation caused by paper slippage or warping. Specifically, the detachable fixing can be achieved using a bolt assembly: the output end face of the second expansion joint 31 is provided with a threaded hole or a flange, and the pressure plate 32 is provided with a corresponding through hole or countersunk hole. After several sets of bolts pass through the pressure plate 32, they are locked and fixed with the threaded hole at the output end, thereby realizing the quick assembly and disassembly of the pressure plate 32; in addition, a slot-type quick-change structure or a magnetic chuck structure can also be used to facilitate the flexible replacement of pressure plates 32 of different sizes or shapes according to different specifications of workbooks; the whole process only requires manual operation and adjustment here.

[0027] The transverse trimming mechanism 5 includes a slanted pushing mechanism 51 and a double-cutting assembly 52 mounted on the frame 1. The slanted pushing mechanism 51 can be a cylinder or an electric push rod, and its output end is fixedly connected to the double-cutting assembly 52 for driving the double-cutting assembly 52 along an oblique direction (e.g., ...). Figure 1 Move in the direction of lower left; the output end of the double-cut component 52 or the oblique push mechanism 51 can be equipped with guide components (such as the existing guide rod and guide sleeve structure) to improve displacement stability; The dual-cutting assembly 52 includes a clamping and adjusting device h and a transverse cutter i fixed on its output end. The clamping and adjusting device h has two sets of output ends that are close to or far apart from each other, which are used to adjust the distance between the two transverse cutters i. Specifically, the clamping device h includes a second housing h1, a second guide bar h2 fixedly installed inside the second housing h1, a second threaded rod h3 rotatably connected inside the second housing h1, a second forward and reverse motor h4 fixedly installed outside the second housing h1, and a second slider h5 slidably connected to the second guide bar h2.

[0028] The outer side of the second housing h1 is fixed to the output end of the inclined push mechanism 51. The threads on the second threaded rod h3 are symmetrically arranged with its center position as the boundary (that is, when one end is a left-hand thread, the other end is a right-hand thread). There are two sets of second sliders h5, which are symmetrically threaded to the front and rear sides of the second threaded rod h3. Each set of second sliders h5 is partially exposed outside the second housing h1 and fixed to a transverse cutter i. A third rangefinder is fixed inside the frame 1 to detect the adjustment displacement of the transverse cutter i. In use, the second forward and reverse motor h4 drives the second threaded rod h3 to rotate. Due to the symmetrical arrangement of the threads on the second threaded rod h3, the two sets of second sliders h5 drive the two transverse cutters i to move closer or further apart synchronously. The third distance measuring device provides real-time feedback of displacement signals to achieve precise adjustment of the distance between the two cutters. The oblique push mechanism 51 pushes the entire double-cutting assembly 52 to move, so that the transverse cutter i can simultaneously cut the front and back sides of the workbook. This structure achieves transverse bilateral synchronous cutting, which is not only highly efficient, but also ensures that the cut edges on both sides are of consistent size and high precision.

[0029] The longitudinal side cutting mechanism 4 includes a fifth telescopic device 41 and a longitudinal cutter 42 fixed at its output end. The fifth telescopic device 41 is a cylinder or hydraulic cylinder with its output end facing downward. The push-adjustment assembly 6 includes a sixth telescopic device 61 fixed to the outside of the frame 1 and an opening 62 opened on the frame 1. The output end of the sixth telescopic device 61 is fixed to the fifth telescopic device 41 and is used to drive the fifth telescopic device 41 to move left and right. Part of the structure of the fifth telescopic device 41 moves within the opening 62. A fourth distance measuring device is fixed to the outside of the sixth telescopic device 61 and is used to detect the displacement of the fifth telescopic device 41 adjusted by the operation of the sixth telescopic device 61. To improve the movement stability of the longitudinal side cutting mechanism 4, a guide assembly 7 is also included. The guide assembly 7 includes a guide rod 71 fixed in the opening 62 and a guide sleeve 72 slidably connected to the outside of the guide rod 71. The outer side of the guide sleeve 72 is fixed to the fifth telescopic device 41. In use, according to the width of the exercise book, the sixth telescopic device 61 drives the fifth telescopic device 41 and the longitudinal cutter 42 to move to the set position. The fourth distance measuring device feeds back the displacement signal, and then the fifth telescopic device 41 drives the longitudinal cutter 42 to move downward to cut the left side of the exercise book longitudinally. Through the precise control of the push-adjustment component 6, it can quickly adapt to exercise books of different widths and achieve precise adjustment of the longitudinal cutting edge.

[0030] Regarding all the telescopic joints used in this device: the first telescopic joint c, the second telescopic joint 31, the third telescopic joint e2, the fourth telescopic joint g1, the fifth telescopic joint 41, the sixth telescopic joint 61, and the oblique pushing mechanism 51 are all pneumatic cylinders or hydraulic cylinders; in order to further improve the cutting accuracy and the stability of position control, this embodiment preferably uses a servo electric cylinder (i.e., a servo electric cylinder), which has a built-in position sensor and communicates directly with the PLC controller. With the help of various rangefinders, it can achieve displacement adjustment with millimeter-level or even higher precision.

[0031] The support mechanism 2 also includes a stabilizing component d; The stabilizing assembly d includes a base d1 fixed to the bottom of the first housing b1, a support platform d2 located at the lower end of the base d1, a ball groove d3 formed at the top of the support platform d2, and universal balls d4 fixed to the bottom of the base d1; the rolling end of the universal ball d4 extends into the ball groove d3 and moves in contact with it; multiple ball grooves d3 are provided and are evenly distributed from front to back at the top of the support platform d2, and each ball groove d3 corresponds to a set of universal balls d4; the outer side of the support platform d2 is fixed to the frame 1; as Figure 1 As shown, each ball groove d3 is fitted with multiple universal ball bearings d4; In use, when the first telescopic component c drives the longitudinal adjustment component b and the entire pallet assembly a to move left and right, the universal ball bearing d4 at the bottom of the base d1 rolls along the ball groove d3 at the top of the support platform d2. This stabilizing component d not only bears the weight of the pallet assembly a and the workbook, reducing the load on the first telescopic component c, but also ensures the straightness and stability of the pallet assembly a when moving left and right through the guiding effect of the ball groove d3, avoiding shaking or skewing during the movement, thereby improving the cutting accuracy.

[0032] The tray mechanism 2 also includes a chip collection component f; The chip collection assembly f includes a connecting plate f1 fixed to the outside of the first housing b1, a guide plate f2 fixed to the outside of the connecting plate f1, and a collection trough f3 fixed to the guide plate f2. The collection trough f3 is located above the support platform d2 and is movably disposed. The projection of the outer periphery of the side moving plate a2 falls on the top of the guide plate f2. During the cutting process, the paper scraps generated by the cutter cutting the edge of the workbook fall down under the action of gravity. Since the guide plate f2 is located directly below the outer periphery of the side moving plate a2, the paper scraps fall directly onto the guide plate f2 and slide down the inclined surface of the guide plate f2 into the collection tank f3. The operator can periodically remove the collection tank f3 for cleaning. This scrap collection component f effectively avoids the accumulation of paper scraps on the workbench surface, which affects the cutting accuracy, while keeping the equipment clean and reducing the frequency of manual cleaning.

[0033] The first, second, third, fourth, and fifth rangefinders mentioned above all use laser displacement sensors [such as the Keyence IL-300 laser displacement sensor]. The IL-300 laser displacement sensor can achieve high-precision detection of displaced components under non-contact conditions, ensuring accurate and rapid position feedback signals from each moving component, thereby providing a reliable positioning basis for the closed-loop control system and significantly improving the consistency and stability of the cutting dimensions.

[0034] This also includes a controller fixed to the outside of the frame 1. The controller is preferably a PLC controller. All the above-mentioned electrical components are electrically connected to the PLC controller. Through the program control of the PLC controller, the automatic expansion and contraction of the pallet assembly a (with closed-loop feedback from the fifth rangefinder), the multi-directional automatic stacking of workbooks, the automatic pressing of the pressure plate, the automatic alignment and cutting of the longitudinal and transverse cutters can be realized, thereby achieving fully automatic or semi-automatic high-precision cutting operations.

[0035] In use: First, according to the size of the workbook to be cut, the parameters are set through the PLC controller. The first forward and reverse motor b5 drives the side plate a2 to move (the fifth distance measuring device provides real-time feedback on the position), so that the support length of the pallet assembly a adapts to the length of the workbook. The third telescopic device e2 drives the first baffle e1 to move to the set width position, and the fourth telescopic device g1 drives the second baffle g2 to move to the set length position. The stacked workbooks are placed on the pallet assembly a, so that one side abuts against the first baffle e1 and one end abuts against the second baffle g2, so as to achieve quick stacking. For the workbooks to be processed, the corresponding pressure plate 32 is installed and used. Then, the second telescopic device 31 drives the pressure plate 32 to press the top of the workbook. The sixth telescopic device 61 drives the longitudinal cutter 42 to move to the set longitudinal cutting position. The fifth telescopic device 41 drives the longitudinal cutter 42 to fall to complete the longitudinal cutting. The oblique push mechanism 51 pushes the double cutting assembly 52 to the cutting station. The second forward and reverse motor h4 drives the two transverse cutters i to adjust to the set spacing. Then, the double cutting assembly 52 moves to complete the transverse double-sided cutting. Paper scraps generated during the cutting process fall into the collection tank f3 via the guide plate f2. The first telescopic device c can drive the tray assembly a to move left and right to facilitate alignment with the cutter. Throughout the process, each rangefinder provides real-time feedback of position signals to ensure cutting accuracy control.

[0036] In summary, this invention effectively solves the technical problems in the prior art, such as paper suspension due to tray fixing, easy burrs during cutting, inconvenient specification switching, and low positioning accuracy, through the longitudinally adjustable structure of the tray assembly a, the multi-directional alignment structure of the lateral adjustment mechanism e and the limiting assembly g, the stable support structure of the stabilizing assembly d, and the synchronous centering adjustment structure of the double-cutting assembly 52. ​​Meanwhile, the inclusion of the chip collection assembly f facilitates equipment cleaning. This device is compact, easy to adjust, and has high cutting accuracy, making it widely applicable to high-precision batch cutting production of workbooks of different specifications.
