Technical Field

[0001] This utility model relates to the field of three-sided book cutter technology, and more specifically, to a quick-release three-sided cutting mechanism. Background Technology

[0002] The three-sided book cutter is a core piece of equipment used for the finishing of books in the post-printing process. It is mainly used to cut the three sides of bound books simultaneously to achieve neat pages, uniform size, and improve the appearance and quality of the finished product. Its design combines mechanical precision and automated control and is widely used in book publishing, commercial printing, packaging printing and other fields.

[0003] However, existing technologies have some problems: existing three-sided knife book cutters require the operator to hold the cutting blade while cutting, and then loosen the fixing bolts one by one for disassembly. However, during the disassembly process, it is not convenient to loosen the fixing bolts while constantly holding the cutting blade, which makes the cutting blade easy to fall during disassembly, causing damage or even injury to the operator, posing a significant safety hazard. Therefore, we propose a quick-release three-sided knife cutting mechanism. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a quick-release three-sided blade cutting mechanism.

[0005] According to a first aspect of this utility model, a quick-release three-sided blade cutting mechanism is provided, including a mounting base and a cutting blade. The cutting blade is detachably connected to the mounting base, and a hanging rod is movably connected to the mounting base. The cutting blade has a hanging hole, and the hanging rod is disposed in the hanging hole. An adjustment component is provided on the mounting base for driving the hanging rod to slide. A correction component is provided on the mounting base for correcting the cutting blade. A positioning component is provided in the middle of the mounting base.

[0006] Optionally, it also includes a fixing bolt, wherein the mounting base has a mounting hole, the cutting blade has a fixing hole, and the fixing bolt passes through the mounting hole and is threaded into the fixing hole.

[0007] Optionally, the mounting base is provided with a sliding groove, and an adjusting rod is slidably connected in the sliding groove, with the hanging rod fixedly connected to one end of the adjusting rod.

[0008] Optionally, the adjusting assembly includes a lead screw, which is rotatably connected in a slide groove, and the adjusting rod has a threaded hole, in which the lead screw is threadedly connected.

[0009] Optionally, one end of the lead screw is provided with a thread, and a locking nut is threadedly connected to the threaded end of the lead screw, the locking nut being used to fix the lead screw.

[0010] Optionally, the adjustment assembly further includes a rotating shaft rotatably connected to a mounting base. A first bevel gear is fixedly connected to one end of the rotating shaft, and a second bevel gear is fixedly connected to the lead screw. The first bevel gear meshes with the second bevel gear, and a drive knob is fixedly connected to the other end of the rotating shaft.

[0011] Optionally, the calibration assembly includes a calibration plate, a guide rod is fixedly connected to the calibration plate, a guide groove is provided on the mounting base, and the guide rod is slidably connected in the guide groove.

[0012] Optionally, a spring is fitted on the guide rod, with one end of the spring fixedly connected to the correction plate and the other end of the spring fixedly connected to the inner wall of the guide groove.

[0016] This utility model is equipped with a correction component. When the cutting blade is moved upward by adjusting the component, the cutting blade will contact the correction plate. Continuing to move upward will push the correction plate to compress the spring and move it upward. At the same time, the guide rod on the correction plate will slide in the guide groove. The guide rod makes the correction plate move horizontally in the vertical direction, thereby keeping the cutting blade horizontal and eliminating the need to calibrate the cutting blade.

[0017] This utility model is equipped with a positioning component. After the cutting blade is installed, the fixing nut is loosened, and then the adjustment knob is turned to make the positioning rod rotate. After the positioning rod rotates, it will move under the thread engagement with the mounting base, thereby driving the positioning block to move, so that the positioning block is in close contact with the correction plate. This allows the cutting blade to be quickly positioned when it needs to be replaced due to wear during the same batch of production, so that the distance of the cutting blade extending out of the mounting base is the same as before, without the need for measurement.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figure 1-6 As shown, a quick-release three-sided blade cutting mechanism includes a mounting base 1 and a cutting blade 2. The mounting base 1 is made of stainless steel, and its main function is to connect the device and fix the cutting blade 2.

[0031] Furthermore, the cutting blade 2 is detachably connected to the mounting base 1. The device also includes a fixing bolt 8. The mounting base 1 has a mounting hole 9, and the cutting blade 2 has a fixing hole 10. The fixing bolt 8 passes through the mounting hole 9 and is threaded into the fixing hole 10. The fixing bolt 8 is used to fix the cutting blade 2.

[0032] Furthermore, a hanging rod 3 is movably connected to the mounting base 1, a hanging hole 4 is provided on the cutting blade 2, the hanging rod 3 is set in the hanging hole 4, a sliding groove is provided on the mounting base 1, an adjusting rod 11 is slidably connected in the sliding groove, and the hanging rod 3 is fixedly connected to one end of the adjusting rod 11.

[0033] Furthermore, the mounting base 1 is provided with an adjustment component 5, which is used to drive the hanging rod 3 to slide. The adjustment component 5 includes a lead screw 51, which is rotatably connected in the slide groove. The adjustment rod 11 has a threaded hole, and the lead screw 51 is threadedly connected in the threaded hole.

[0034] Specifically, one end of the lead screw 51 is threaded, and a locking nut 53 is threadedly connected to the threaded end of the lead screw 51. The locking nut 53 is used to fix the lead screw 51.

[0035] Furthermore, the adjustment assembly 5 also includes a rotating shaft 54, which is rotatably connected to the mounting base 1. A first bevel gear 55 is fixedly connected to one end of the rotating shaft 54, and a second bevel gear 56 is fixedly connected to the lead screw 51. The first bevel gear 55 meshes with the second bevel gear 56, and a drive knob 52 is fixedly connected to the other end of the rotating shaft 54.

[0036] Specifically, when installing the cutting blade 2, the cutting blade 2 is suspended on the hanging rod 3 through the hanging hole 4. Then, by loosening the locking nut 53, the drive knob 52 is rotated. After the drive knob 52 rotates, it will drive the first bevel gear 55 to rotate through the rotating shaft 54. After the first bevel gear 55 rotates, it will drive the second bevel gear 56 to rotate, thereby driving the lead screw 51 to rotate. After the lead screw 51 rotates, it will move under the thread engagement with the adjusting rod 11, thereby driving the hanging rod 3 and the cutting blade 2 on it to move. After the cutting blade 2 moves to the appropriate position, the locking nut 53 is tightened to fix the cutting blade 2 in the current position, and then it is fixed to the mounting base 1 by the fixing bolt 8.

[0037] Furthermore, when disassembling the cutting blade 2, the fixing bolt 8 is loosened, and then the locking nut 53 is loosened. The drive knob 52 is rotated to lower the hanging rod 3, which in turn lowers the cutting blade 2, making it easier to remove the cutting blade 2. By adjusting the component 5, when installing or removing the cutting blade 2, the operator does not need to support the cutting blade 2. The hanging rod 3 will support the cutting blade 2. The operator only needs to tighten or loosen the fixing bolt 8 to complete the installation or removal. This facilitates the operation of the staff and avoids the cutting blade 2 from falling during the installation and removal process, which could damage the cutting blade 2 or even injure the operator.

[0038] Furthermore, a correction component 6 is provided on the mounting base 1. The correction component 6 is used to correct the cutting blade 2. The correction component 6 includes a correction plate 61. A guide rod 62 is fixedly connected to the correction plate 61. A guide groove is provided on the mounting base 1. The guide rod 62 is slidably connected in the guide groove.

[0039] Furthermore, a spring 63 is fitted onto the guide rod 62, with one end of the spring 63 fixedly connected to the correction plate 61 and the other end of the spring 63 fixedly connected to the inner wall of the guide groove.

[0040] Specifically, when the cutting blade 2 is moved upward by the adjusting component 5, the cutting blade 2 will contact the correction plate 61. Continuing to move upward will push the correction plate 61 to compress the spring 63 and move it upward. At the same time, the guide rod 62 on the correction plate 61 will slide in the guide groove. The guide rod 62 makes the correction plate 61 move horizontally in the vertical direction, so that the cutting blade 2 remains horizontal and there is no need to calibrate the cutting blade 2.

[0041] Furthermore, a positioning component 7 is provided in the middle of the mounting base 1. The positioning component 7 includes a positioning rod 71. An adjustment hole is provided on the mounting base 1. The positioning rod 71 is threaded into the adjustment hole. A fixing nut 72 is threaded onto the positioning rod 71. The fixing nut 72 is used to fix the positioning rod 71.

[0042] Furthermore, one end of the positioning rod 71 is fixedly connected to an adjustment knob 73, and the other end of the positioning rod 71 is rotatably connected to a positioning block 74, which is positioned above the calibration plate 61.

[0043] Specifically, after the cutting blade 2 is installed, the fixing nut 72 is loosened, and then the adjusting knob 73 is turned to make the positioning rod 71 rotate. After the positioning rod 71 rotates, it will move under the thread engagement with the mounting base 1, thereby driving the positioning block 74 to move, so that the positioning block 74 is in close contact with the correction plate 61. This allows the cutting blade 2 to be quickly positioned when it needs to be replaced due to wear during the same batch of production, so that the distance of the cutting blade 2 extending out of the mounting base 1 is the same as before, without the need for measurement.

[0044] The aforementioned quick-release three-sided blade cutting mechanism allows for easy removal of the cutting blade 2 by loosening the fixing bolt 8, then loosening the locking nut 53, and rotating the drive knob 52 to lower the hanging rod 3, thereby lowering the cutting blade 2. The adjustment component 5 ensures that the cutting blade 2 can be installed or removed without operator support, as the hanging rod 3 provides support. Operators only need to tighten or loosen the fixing bolt 8 to complete the installation or removal. This facilitates operation and prevents the cutting blade 2 from falling during installation or removal, thus avoiding damage or injury to the operator.

[0045] This utility model is equipped with a correction component 6. When the cutting blade 2 is moved upward by the adjustment component 5, the cutting blade 2 will contact the correction plate 61. If it continues to move upward, it will push the correction plate 61 to compress the spring 63 and move upward. At the same time, the guide rod 62 on the correction plate 61 will slide in the guide groove. The guide rod 62 makes the correction plate 61 move horizontally in the vertical direction, so that the cutting blade 2 remains horizontal and there is no need to calibrate the cutting blade 2.

[0046] This utility model is equipped with a positioning component 7. After the cutting blade 2 is installed, the fixing nut 72 is loosened, and then the adjusting knob 73 is turned to make the positioning rod 71 rotate. After the positioning rod 71 rotates, it will move under the thread engagement with the mounting base 1, thereby driving the positioning block 74 to move, so that the positioning block 74 is in close contact with the correction plate 61. This allows the cutting blade 2 to be quickly positioned when it needs to be replaced due to wear during the same batch of production, so that the distance of the cutting blade 2 extending out of the mounting base 1 is the same as before, without the need for measurement.
