[0031] Please refer to Figure 1 - Figure 7 This utility model provides a cutting device for a chopsticks machine, including a frame 1, a mounting base 2, a blade holder 3, a cutting blade 30, an XY drive module 4, an adjusting rod 5, a fixed base 6, and a fixing block 7. The cutting blade 30 is mounted on the blade holder 3, which is mounted on the mounting base 2. The XY drive module 4 is mounted on the frame 1 and drivenly connected to the mounting base 2. The XY drive module 4 drives the mounting base 2 to move along the horizontal X-axis and horizontal Y-axis directions.
[0032] Reference Figure 7The XY drive module 4 includes an X drive module 40 and a Y drive module 41. The X drive module 40 is mounted on the frame 1 and drivenly connected to the Y drive module 41, used to drive the Y drive module 41 to move along the horizontal X-axis. The Y drive module 41 is drivenly connected to the mounting base 2, used to move the mounting base 2 along the horizontal Y-axis. Both the X drive module 40 and the Y drive module 41 can be linear drive modules. In other embodiments, the X drive module 40 can be an electric push rod or a linear drive motor, and the Y drive module 41 can be a linear drive module.
[0033] Reference Figure 1 - Figure 6 A fixing seat 6 is mounted on a mounting base 2. A T-slot 60 is provided on the fixing seat 6, communicating with the upper surface of the fixing seat 6. The T-slot 60 extends along the horizontal X-axis and passes through both ends of the fixing seat 6. A fixing block 7 is fixed within the T-slot 60, and a first threaded hole 70 is provided on the fixing block 7 along the horizontal X-axis. One end of the tool holder 3 is slidably connected to the T-slot 60, and the other end of the tool holder 3 extends vertically out of the T-slot 60. The cutting tool 30 is located outside the T-slot 60 and extends along the horizontal Y-axis. A second threaded hole 32, coaxial with the first threaded hole 70, is provided on the tool holder 3. Furthermore, an adjusting rod 5 is provided with a first thread 50 and a second thread 51. The pitches of the first thread 50 and the second thread 51 are different. The first thread 50 is threadedly connected to the first threaded hole 70, and the second thread 51 is threadedly connected to the second threaded hole 32. The end of the adjusting rod 5 facing away from the fixing block 7 is located outside the tool holder 3.
[0034] In summary, it can be understood that the XY drive module 4 drives the mounting base 2 to move the cutting blade 30 on the blade holder 3 along the horizontal X-axis and horizontal Y-axis directions, so as to adjust the position of the cutting blade 30 in cutting the chopsticks. However, since the XY drive module 4 cannot achieve precise fine-tuning of the cutting tool 30, in order to achieve precise fine-tuning of the cutting tool 30, the tool holder 3 is slidably connected to the T-slot 60 on the fixed seat 6, and the first thread 50 and the second thread 51 on the adjusting rod 5 are threadedly connected to the first threaded hole 70 on the fixed block 7 and the second threaded hole 32 on the tool holder 3, respectively. Since the pitches of the first thread 50 and the second thread 51 on the adjusting rod 5 are different, the first thread 50 and the second thread 51 on the adjusting rod 5, the first threaded hole 70 on the fixed block 7 and the second threaded hole 32 on the tool holder 3 will form a differential screw drive mechanism. Since the fixed block 7 is fixed and the pitches of the first thread 50 and the second thread 51 are different, when the adjusting rod 5 is rotated, the cutting tool 30 will move slightly along the axial direction of the adjusting rod 5 with the tool holder 3, thereby achieving the precise fine-tuning effect of the cutting tool 30.
[0035] It should be noted that the principle of differential screw drive is as follows:
[0036] The differential screw drive mainly consists of three components: a screw (equivalent to the adjusting rod 5 mentioned above), a fixed nut (equivalent to the fixed block 7 mentioned above), and a movable nut (equivalent to the tool holder 3 mentioned above). The screw typically has two threads with different leads (the lead of a thread is determined by its pitch; different pitches result in different leads) or directions of rotation, forming two helical pairs with the fixed nut and the movable nut respectively. When the threads of the two helical pairs have the same direction of rotation, the movement distance of the movable nut decreases because the two helical pairs produce movement in opposite directions, thus canceling out some of the movement distance. When the threads of the two helical pairs have opposite directions of rotation, the movement distance of the movable nut increases because the two helical pairs produce movement in the same direction, thus adding up the movement distance. Assuming that the fixed nut and the movable nut both have right-hand (or both have left-hand) rotation, when the screw is rotated, the screw moves to the left (or right) relative to the fixed nut, while the movable nut moves in the opposite direction relative to the screw. In this way, the movable nut achieves differential movement relative to the fixed nut. For every one revolution of the screw, the actual distance the movable nut moves is the difference between the lead of the two thread segments.
[0037] In one embodiment, reference is made to Figure 1 - Figure 6 In one embodiment, the first thread 50 and the second thread 51 on the adjusting rod 5 have the same direction of rotation. Therefore, when the adjusting rod 5 is rotated, the tool holder 3 moves less axially along the adjusting rod 5. In another embodiment, the first thread 50 and the second thread 51 have opposite directions of rotation. Therefore, when the adjusting rod 5 is rotated, the tool holder 3 moves more axially along the adjusting rod 5. In summary, regardless of whether the first thread 50 and the second thread 51 on the adjusting rod 5 have the same or opposite directions of rotation, precise fine-tuning of the cutting tool 30 can be achieved.
[0038] In one embodiment, reference is made to Figure 1 - Figure 6 The adjusting rod 5 has a knob 52 located outside the tool holder 3 at one end facing away from the fixing block 7. The knob 52 is used to rotate the adjusting rod 5. Specifically, the knob 52 can be configured as an external hexagonal knob 52 adapted to an internal hexagonal wrench, so that the knob 52 can be driven by the internal hexagonal wrench, thereby driving the adjusting rod 5 to rotate. Of course, in other embodiments, the knob 52 can also be configured as a manual knob.
[0039] Based on the above structure, referring to Figure 1 - Figure 6A locking component 8 is provided on the fixing block 7. The locking component 8 is used to lock or unlock the sliding of the blade holder 3 relative to the T-slot 60. That is, when the blade 30 needs to cut chopsticks fixed on the clamp 91 of the chopstick machine, the locking component is in the locked state, pressing the blade holder 3 tightly into the T-slot 60; when the blade 30 needs to be fine-tuned, the locking component is in the unlocked state. Specifically, the locking component includes an adjusting bolt 81 and a clamping block 80. The clamping block 80 is placed on the upper surface of the blade holder 3. The adjusting bolt 81 passes vertically through the clamping block 80 and is threadedly connected to the fixing block 7, so that the clamping block 80 can lock or unlock the sliding of the blade holder 3 relative to the T-slot 60. When the blade 30 needs to be fine-tuned, the adjusting bolt 81 is loosened to unlock the clamping block 80 and press the blade holder 3; when the blade 30 needs to cut chopsticks, the adjusting bolt 81 is tightened to lock the clamping block 80 onto the blade holder 3.
[0040] In one embodiment, reference is made to Figure 1 - Figure 6 The tool holder 3 has a receiving groove 31 extending along the horizontal Y-axis. The cutting tool 30 is slidably connected to the receiving groove 31. The tool holder 3 also has a locking element 9, which is a locking bolt, used to lock the sliding of the cutting tool 30 relative to the receiving groove 31. Specifically, the tool holder 3 has a third threaded hole (not shown), extending along the horizontal X-axis and communicating with the receiving groove 31. The locking element 9 is threadedly connected to the third threaded hole. Thus, by tightening the locking element 9, the sliding of the cutting tool 30 relative to the receiving groove 31 can be locked. When it is necessary to replace a different cutting tool 30, simply loosen the locking element 9. In addition, a fourth threaded hole (not shown) is provided on the tool holder 3. The fourth threaded hole extends vertically and passes through the receiving groove 31. The fourth threaded hole is also threadedly connected to a locking member 9, which can further lock the cutting tool 30 to slide relative to the receiving groove 31. It can be seen that the solution of locking the cutting tool 30 to slide relative to the receiving groove 31 by locking the cutting tool 30 can replace cutting tools 30 of different specifications.
[0041] To achieve batch cutting of chopsticks, multiple fixed seats 6 are provided, spaced apart along the horizontal X-axis. Each fixed seat 6 has at least one cutter holder 3, with two cutter holders on each fixed seat 6. Correspondingly, an adjusting rod 5 is threadedly connected to each cutter holder 3. The first threaded holes 70 on both sides along the horizontal X-axis of each fixed block 7 are respectively connected to the first thread 50 on the two adjusting rods 5. Each cutter holder 3 is provided with a cutting blade 30. A fixed block 7 is fixed in the receiving groove on each fixed seat 6. The locking components on each fixed block 7 lock or unlock the cutter holders 3 on each fixed seat 6 to slide relative to the T-slots 60 on each fixed seat 6. Of course, multiple chucks 91 are also provided on the chopstick machine. Each chuck 91 is driven to rotate by the drive structure on the chopstick machine. Naturally, the multiple chucks 91 correspond one-to-one with the multiple fixed seats 6. In this way, the knife holders 3 on each fixed seat 6 can move synchronously along the horizontal X-axis or synchronously along the horizontal Y-axis with the mounting seat 2, and can also be independently fine-tuned, so that the cutting effect of the cutting device of the chopstick machine is better.
[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
